Discussion of Environmental Evaluation (Narrative description of environmental impacts.) 1 ' IV. Determination On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant ' effect on the environment, and a NEGATIVE DECLARATION WILL BE 0 PREPARED. I find that although the proposed project could have a signif- icant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE DECLARATION WILL BE PREPARED. ' I find the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IHPACT REPORT is required. 0 Date Signature ' C\PLT\EIRLIST.FRM For -7 1 ' ATTACHMENT A ' CASTAWAYS MARINA PROJECT DESCRIPTION ' The California Recreation Company, a subsidiary of The Irvine Company, proposes to ' construct a 125-slip marina within a coastal area of Newport Beach (see Figure 1). The site is located on the northwestern portion of the Newport backbay in an area ' previously utilized as a disposal site for Newport Bay dredge spoils. The site, known as lower Castaways, is adjacent to the Newport backbay (see Figure 2). ' The proposed Castaways Marina site consists of land and open -water areas totaling approximately 4.0 acres. The 2.5 acre land portion is bordered on the east by the ' Newport backbay, on the west by Dover Drive, on the south by Coast Highway, and on the north by a 60 foot natural and man-made bluff. Access from land to the proposed marina will be from Dover Drive via Coast Highway. Boats will pass under ' the Coast Highway bridge to gain access to the slips. ' The marina will consist of floating and pile supported facilities; no hotels, restaurants or snack facilities will be constructed as part of the project. A sanitary ' pump station will be located onsite. No fueling stations will be located in the marina. Two onsite fire hydrants and a fire hose cabinet with 75 foot hoses will provide fire protection for the floating structures and boats. Restrooms, showers, utilities, trash_ containers and storage facilities will be located in a 50 x 20 feet ' building at the northwest end of the marina basin. A public viewing area will be located near the building and landscaping will be provided in the circular areas near ' the viewing area and parking areas. A total of 108 parking spaces will be provided at the east and north sides of the basin. ' An 880-foot long concrete pile -supported floating pier will provide access to the slips in the bay. The pier will be constructed of pressure -treated wood framing and will ' support 73 slips or tie-up locations. Two floating main walkways will provide access to the marina basin slips. Each walkway will be 6 feet wide and will be constructed ' of precast concrete floats, glue laminated wood stringers, wood plank decking and wood fascias. The floating slip fingers will be 4 feet wide in width. Piers will be stabilized with approximately 162 concrete or steel pilings. 1 JBX/0640007B1 A 20-foot high steel sheet pile bulkhead with a concrete cap and deadman will be ' located along the east, north and south ends of the marina basin. Antifouling coating.and cathotic protection will be required for that bulkhead. Rock rip -rap will , be placed at the toe of the bluff, at the northwest and southwest corners of the marina basin. Two retaining walls along the north side of the basin, inboard of the bulkhead, will also be constructed. The Castaways Marina will consist of 125 slips of four sizes as shown in Figure 3 and ' described below: • Fifty-two, 45-foot slips • Thirty-nine, 42-foot slips , • Nineteen, 38-foot slips • Eight, 35-foot slips , • Seven side tie locations. ' The slips are designed for power boats and small sailboats capable of passing under the limited vertical clearance beneath the Coast Highway. Construction will consist of dredging, removal of existing bulkheads and installation ' of onshore and over -water structures. Dredging of approximately 769000 cubic yards (cy) will be required to create the , marina basin and access channel to the floating pier and slips. Maximum dredge depth will be to -10.75 feet (mean sea level). Approximately 56,000 cy of material ' will be removed from behind the existing bulkhead and 20,000 cy from the bay (see Figure 4). Bulldozers will excavate the surficial, dry sediments behind the bulkhead, while sediments below the water table behind the bulkhead will be removed by clamshell dredge. Waterside dredging will be completed by hydraulic, diesel -driven ' equipment. Disposal of all dredge materials will be at the Upper Castaways site ` shown in Figure 5. The proposed disposal site is an open, flat area located off Dover Drive, northwest of the marina site. Access to the disposal site would be along 2 JBX/0640007B1 ' Regional Map Castaways Marina o j.

The reader is requested to refer to the numbering sequence on the forms which correspond to the numbered items in the left column of this document. Environmental Information Form Page 2 Item 21: Removal of approximately 76,000 cubic yards of dry fill and bay material will be completed in order to provide the main boat basin and access channel. Item 22: The existing vacant land will be altered to a 125-slip marina; public viewing areas are also planned around the marina. Item 23: The existing vacant land, which supports ruderal vegetation, will be altered to an open water marina. Item 24: No significant volumes of waste materials are expected. Item 25: During construction some dust could be generated; dredging of bay sediments could result in short-term increases in odors. Item 26: The marina basin will increase the surface area of Newport Bay by approximately 2.5 acres. Preliminary sediment and water quality studies of the dredge area indicate no significant pollutant levels are present. Drainage patterns will be altered due to the reduction of land at the site. Item 27: Construction noise and vibration levels will result in short-term increased levels from existing conditions; noise from the additional boats would also result in minor noise increases. Item 28: The Castaways Marina is proposed for an area that was created from dredged material. Slopes are less than 10 percent. JBX/0640007B1 1 I u Item 29: No fuel facilities or hazardous materials will be present at the marina. t Item 30: No substantial increases in municipal services are expected although security, fire protection and utilities will be required. ' Item 31: No substantial increases in fuel usage is expected; motorized boats will utilize fuel obtained elsewhere in ' Newport Bay. Construction activities will use minor amounts of fuel. Item 32: The proposed marina (125 slips) is a single project and is not related to any others. Environmental Checklist Form Page 1 Item i(a): No unstable earth conditions are known to exist in the , project area; bluffs to the north of the site will be secured by low retaining walls along the marina property boundary. Rip -rap will be placed at corners of the marina basin to reduce erosion. ' Item 1(b): Removal of approximately -172,000 cubic yards of dry and wet sediment is proposed. , Item 1(c): Existing flat fill areas will be removed through dredging; disposal of the dredge material will add approximately 1.5 feet of height to the Upper Castaways disposal site. ' Item 1(d): No unique geological features (bluffs, etc.) will be altered, ' Item 1(e): Potential erosion of the dredge area will be reduced through the use of bulkheads and retainer walls. Reduced erosion of the site will result from the removal of erosive soils. Item 1(f): Increased water depths within the basin and along the ' detached slip pier could result in increased flows within Newport Bay. Decreased siltation into the Bay is expected due to the removal of the existing fill material. Item 1(g): No increases in exposure to geologic hazards are expected as no onshore amenities are proposed at the marina. , Page 2 Item 2(a): No significant increases in air emissions are expected; short-term increases in emissions from construction are expected to be insignificant. 2 JBX/0640007131 I C' 1 'J Item 2(b): Dredging of bay sediments could result in short-term increases in odors. Item 2(c): The proposed marina will not alter existing climatic conditions. Item 3(a): Dredging of the main basin and channel may alter local current flow within the area; ongoing engineering studies will analyze these potential changes. Item 3(b): Reduced absorption and surface runoff will result from the removal of existing fill material; reduced siltation into the Bay is also expected. Item 3(c): No significant alteration of flood waters is expected from the dredged basin. Item 3(d): An additional 2.5 acres of surface water in Newport Bay is expected from dredging of the main basin. Item 3(e): Dewatering of the wet materials will result in discharge into the Bay. Previous sediment and water chemistry analyses indicate no significant water quality impacts are likely. Item 3(f): Ground water flow is not expected to be altered by proposed activities. Item 3(g): Freshwater sources (groundwater) are distant from the proposed marina; saltwater intrusion is not expected to result from the increased area of the Bay. Item 3(h): Water for boat washdown and drinking sources will be available at the marina. No significant increases in usage is expected. Item 3(i): The marina will be exposed to flooding or tidal waves, similar to other facilities within the Bay. The exposure is expected to be minor and ample warning of such occurrences from existing information sources is expected to reduce the potential for significant impact. Page 3 Item 4(a): A biological survey of the disposal site has been conducted; no unique habitats exist at either the proposed marina site or disposal area. A wetland area on the west side of the disposal area will not be impacted. Eucalyptus trees and other perennial plants maybe impacted by the disposal of the material. Changes in the existing plant life could result from dredge disposal and removal of existing vegetation within the dredge area will occur. JBX/0640007B1 3 Item 4(b): No unique or rare plant species exist at the project sites, although several stands of perennial trees are present ' around the periphery of the disposal site. Impacts to those resources are possible. Item 4(c): New plant species could be expected to occur in the ' disposal area due to the presence of different soils from those naturally occurring. Landscape vegetation around the marina will differ from existing plants. Item 4(d): No agricultural activities currently exist within either the marina or dredge disposal sites. Item 5(a): Loss of existing habitats could result in reduction of existing animal life. No sensitive species are known to inhabit the site areas. ' Item 5(b): No unique, rare or endangered animal species are known to occur at the sites, although the California least tern , does utilize Upper Newport Bay for feeding. This species is not expected to be affected by the proposed activities. Item 5(c): No new animal species are expected to inhabit the area; , an increased water area could provide additional habitat for bay fishes. ' Item 5(d): No significant deterioration of existing habitats is expected. Alteration of existing fill area and disposal of dredge materials at Upper Castaways will reduce the non -unique ruderai habitats. Increased water areas will ' increase the habitat for aquatic organisms. Item 6(a): Short-term, construction -related noise increases could ' result from dredging, disposal and pile driving activities. Item 6(b): No significant increases in noise levels to residential , areas are expected due to the distance from the site and buffers between source and receptors. Disposal - generated noise at Upper Castaways is expected to be minor and short-term. , Item 7: Possible increases in lighting around the marina is expected to be minor and localized. ' Item 8: The site and the Upper Castaways disposal area are currently unoccupied; the marina site is zoned marine recreational and commercial, thus no conflicts with ' existing land use are expected. Page 4 Item 9(a): No significant increase in the use of natural resources is expected from the proposed project. Fuel will not be , 4 JBX/0640007131 ' available at the site and the increased boat slips and resulting boat usage is expected to be minor. ' Item 10(a): Accidents related to boat traffic could result in the release of minor amounts of fuel; however, no refueling services will be available at the marina and no hazardous ' materials will be stored. The chances of significant boat accidents occurring are considered unlikely. Item 10(b): No interference with evacuation/response plans is ' expected. The marina is "self-contained" and is not expected to impact the orderly evacuation of the area. ' Item 11(a): No increase in population is expected from the project. Mooring facilities will be limited to small vessels and no food, fuel or service facilities are planned for the marina. Construction crews are expected to be from ' local sources. ' Item 12: No additional housing is required for construction or operation personnel. Item 13(a): Traffic counts for similar marinas within Newport Beach have been conducted. These data indicate that vehicle ' traffic generated by the operation of the project• may approach the level which will necessitate a traffic study. In addition, truck traffic generated• during ' construction may reach potentially significant levels for a short period of time. ' Item 13(b): Parking requirements for the marina will be less than the proposed number of parking areas. Item 13(c): Truck traffic along Dover Drive may impact existing ' levels of service; a separate traffic lane for trucks transporting dredged material is planned to minimize ' such impacts. No final decision on the need for a specific traffic study has been made. Item 13(d): Alterations of existing traffic patterns are not expected due to the proposed parallel truck lane. Entrance to the ' marina will be via Dover Drive through an existing driveway. ' Item 13(f): Increased hazards to bicycle, motor vehicle or pedestrian traffic are not anticipated. Further analysis and locations of cross walks and/or turning lanes will be ' completed prior to project initiation. Item 14(a): Additional service for fire protection will be required, although onsite fire fighting equipment (e.g. hydrants, ' fire extinguishers) will be included in final design. J JBX/0640007B1 F Item 14(b): Increased patrolling of the area will be required. Item 14(c): No additional schools will be required due to the insignificant increase in population related to the marina (see 11 above). Item 14(d): The facility will increase available recreation facilities including public viewing areas and recreational boat slips. No additional facilities within the city will be required. Item 14(e): Responsibility for maintenance of the facilities will be determined prior to initiation of the project. Item 14(f): No other government services would be required by the marina. Page 5 Item 15(aft): No substantial increase in energy (fuel or electricity) is required, as no substantial public facilities or fuel stations are planned for the marina. Item 16(a-f): With the exception of the proposed sewage pumpout station, utilities for the marina will be hooked into existing sources. Removal of grey water and bilge waste from the pumpout station and sanitary waste from the restrooms will require hookup to existing facilities. Item 17(a6cb): No increase in health hazards are expected from the marina. Existing boat traffic within the Bay may be locally impacted by the expected insignificant increase in the chance for a boating accident. Page 6 Item 18: The existing vistas of the site are limited to those from Dover Drive and Coast Highway. The aesthetics of the site are expected to be significantly improved over the existing vacant land with ruderal plants. Increased viewing area from the marina will provide increase opportunities for the public to observe Upper Newport Bay. Item 19: Recreational opportunities, including access to a currently restricted area, are expected to significantly Increase with the marina providing opportunities for recreational boating. Item 20(a-d): Although no buildings currently exist onsite, the Upper Castaways disposal area was the previous site of the Castaways commercial buildings. No archaeological or cultural surveys are known to have been recently conducted at the marina site or proposed dredge disposal area. The church and parking lot that currently exists on 6 JBX/0640007B1 I J I 11 u H I F F C I 1 fl 1 I 1 1 1 i 1 I 1 1 1 J 1 H a portion of the disposal site will not be affected by the proposed action. Item 21(a): Dredging of bay sediments and disposal of dredge materials will alter the current habitats and species. Significance of the resources are, however, not completely known at this time. Item 21(b): No long-term detrimental impacts are anticipated from the proposed project. Alteration of existing, nonunique habitats will result in long-term increases in available recreational facilities and water -related habitat for aquatic species. Item 21(c): With the exception of potentially minor traffic increases, no cumulative impacts are currently anticipated. Item 21(d): No substantial, unmitigable impacts are expected from construction and/or operation of the marina. Increases in public access, aquatic habitat, recreational facilities and aesthetic quality balance the short-term traffic and noise increases previously discussed. Page 7 Item III: Summarizing the issues discussed above, the following impacts could be expected for the proposed marina: JBX/0640007131 • Displacement of soil and alteration of existing topography related to dredging and disposal of dredge material. - • Potential changes in erosion potential of exposed soils. • Alteration of existing channels within the Bay. • Potential short-term increase in odors due to highly organic soil conditions within the dredge area. • Changes in water runoff and absorption due to decreased land and increased water surface areas. • Discharges of some dredge material water into the Bay during dewatering of wet sediments. A sediment chemistry and elutriate study of samples taken from within the offshore dredge area was conducted in January, 1988. Results of that analysis indicate no significantly elevated levels of pollutants in the dredge material. • Positive impacts to aquatic biota are expected due to the increase in water area. 7 1 I L� Alteration or loss of existing terrestrial habitats is expected to result from removal of existing soil and deposition of dredge material on existing ruderal habitats. Likewise, alteration of aquatic habitats will result from dredging activities within the Bay. , A biological survey of the proposed dredge disposal area at Upper Castaways was conducted in February, 1988. A potentially sensitive wetland area was Identified within the 57 acre site. No disposal of r dredge materials into that habitat will occur. • Short-term increases in noise generated by construction equipment is expected. Sensitive ' receptors north and northwest of the Upper Castaways disposal site could be subjected to Increased noise from trucks. Other noise generators would be located at the dredge site including the dredges graders, pile drivers and trucks. • Potential traffic and circulation increases could result from the construction and operation of the marina. Three traffic counts were conducted at the Bayshores Marina and a single three-day count was also conducted at Newport Dunes Marina, both within the City of Newport Beach. Results of these counts Indicate the potential for traffic generated by Castaways Marina to approach the limit that would Initiate. the City's Traffic Phasing Ordinance. However, it should be noted that both of the surveyed marinas are larger than the proposed Castaways Marina and both have other amenities (e.g., public phones, restaurants) that will not be present at Castaways. Final analysis of the traffic , count data will determine the need for a traffic study. Potential increases in the construction - related traffic would result from trucks traversing Dover Drive to the Upper Castaways disposal site. A ' parallel roadway is proposed along Dover Drive to accommodate that truck traffic. ; • Some additional services, in the form of security and fire, may be required for the marina. Onsite fire -protection equipment (hoses and extinguishers) will , augment the City's existing equipment. Final determination and limitation of fireboat access to the marina will be made during the EIR process. • The facility will provide for increased public access to the Bay and increased recreational opportunities. The current limited access will be replaced by an open space, water views and recreational boating facilities. , JBX/0640007B1 ' NOTICE OF PREPARATION Dept. of Army CalTrans - DOTP L.A. Dist.

An NOP for the proposed marina ' was originally distributed by the City of Newport Beach in August 1988 (SCH# 88081016). An environmental impact report (EIR) was never completed for the project addressed in the original NOP. Due ' to revisions to elements of the proposed project, the NOP is hereby revised and redistributed. This NOP addresses a marina of the same size and location as was ' addressed in the original NOP. The primary difference between the originally -proposed project and the currently -proposed project is the revised set of dredged material -disposal site alternatives. ' The previously -evaluated disposal site alternatives included 4 offsite parcels located adjacent to Upper Newport Bay. The current proposal is considering 2 different alternative disposal sites: (1) ' Coyote Canyon Landfill, and (2) an ocean disposal site (to be approved by the U.S. Environmental Protection Agency and U.S. Army Corps of Engineers).

The site is located in the southwestern portion of the Upper Newport Bay in an area previously utilized as a disposal site for Newport Bay dredge spoils. The land portion of the site is known as the "Lower Castaways" site (see Exhibit 2). PROJECT ELEMENTS The proposed Castaways Marina site consists of land and open -water areas totaling approximately 8.0 acres. The 4.0-acre land portion ("Lower Castaways") is bordered on the east by the Upper Newport Bay, on the west by Dover Drive, on the south by Coast Highway and the Coast Highway Bridge, and on the north by a 60-foot-high natural and man-made bluff. Automobile access to the -proposed marina will be from Dover Drive via Coast Highway. Boats will pass under the Coast Highway Bridge to gain access to the slips. The marina will consist of floating and pile -supported facilities; no fueling stations, hotels, restaurants, or snack facilities will be constructed as part of the project. A sanitary pump station will be located onsite. Two onsite fire hydrants and fire hose cabinets with 75-foot hoses will provide fire protection for the floating structures and boats. Restrooms, showers, utilities, trash containers and storage facilities will be located at the northeast corner of the marina basin. A public viewing area will be located at the end of the paved parking area and landscaping will be provided in the circular areas near the viewing area and parking areas. A total of 106 parking spaces will be provided at the west and north sides of the basin. 1 JBX/0640007B1 I The Castaways Marina is proposed to consist of seven side tie locations and 118 slips of four sizes as shown in Exhibit 3 and described below: ' • Flfty-twos 45-foot slips ' • Thirty-nine, 42-foot slips • Nineteen, 38-foot slips • Eight, 35-foot slips The slips are designed for power boats and small sailboats capable of passing under the limited vertical clearance beneath the Coast Highway Bridge. ' An 880-foot-long concrete pile -guided floating mainwalk will provide access to a , portion of the slips. This mainwalk will be constructed of pressure -treated wood framing and will support 64 slips or side tie-up locations. Two additional floating main walkways will provide access to the 61 marina basin slips and side tie-ups. Construction is expected to occur over a 12- to 16-month period and will consist of ' removal of the existing bulkhead, installation of new bulkheads, dredging and disposal of dredged material, and installation of onshore and over -water structures. ' Installation of new bulkhead walls is expected to occur in the first 2 to 3 months of , the construction phase. Bulkheads will consist of a tie -back system utilizing steel sheetpiles with reinforced concrete cap, cathodically protected tie rods, and t reinforced concrete deadmen. Steel sheetpiles will have both a protective coating as well as an impressed cathodic protection system for corrosion protection. Exhibit 4 presents the proposed dredge operation plan. Dredging of approximately 80,000 cubic yards (cy) will be required to create the marina basin and access channel to the floating pier and slips. Approximately 56,000 cy of material will be removed from behind the existing bulkhead and 24,000 cy from the bay. Dredging is expected to occur over 3 to 4 month, following bulkhead installation. It is expected that bulldozers will excavate the surficial dry sediments behind the , bulkhead, while sediments below the water table will be removed by clamshell dredge. Waterside dredging will be completed by hydraulic, diesel -driven equipment.

These options are described below and shown on Exhibit 5. ' (1) 100% Disposal to Coyote Canyon Landfill — Disposal to Coyote Canyon Landfill would commence once the landfill is reconvened from the County of Orange to The Irvine Company. Drying of wet materials to acceptable ' levels would occur on the Lower Castaways site. It is estimated that approximately 49000 truckloads of material would be transported to the disposal site. The truck route to and from the landfill is proposed to include the following streets: 16th Street, Dover Drive, Coast Highway, Jamboree Road, Bison Avenue, MacArthur Boulevard, Bonita Canyon Road, and Coyote Canyon Road (see Exhibit 5). ' Haul trucks for the dredged material would enter the site from northbound Dover Drive with a right -turn, movement. To provide an exit or egress route for the loaded haul trucks, it is proposed that a temporary (dirt) haul road be provided from the Lower Castaways site to the ' easternmost (dead) end of 16th Street via the property directly north of the site, referred to as the "Upper Castaways" site. This road, which would be approximately 29100 feet in length, would begin along the Dover ' Drive side of the Upper Castaways site (utilizing a portion of an existing dirt road), then would turn northward around the back (easternmost) side of the church located on the Upper Castaways site. Trucks would then enter 16th Street at its dead-end and turn left at the Dover Drive ' intersection to begin -their trip to the landfill (as depicted on Exhibit 5). Preparation of this temporary road, all on private property, would require ' grading along approximately half its length. As proposed, it would be designed for one-way (outbound) traffic only, and would avoid areas of sensitive habitat on the Upper Castaways site. (2) 100% Disposal to Approved Ocean Site — Disposal at an ocean site is ' dependent upon a formal bioassay and approval by the U.S. Environmental Protection Agency and U.S. Army Corps of Engineers. The proposed site, ' referred to as "LA-3," is a site off the coast of Newport Beach which has previously received U.S. Army Corps of Engineers' certification for dredged material disposal. Ocean disposal of the dredged material could include as few as 25 and as many as 80 barge (or scow) loads of material, ' depending on the contractor's equipment and methods. These methods JB%/0640007B1 LI are yet to be determined, but may include the use of tugs and barges (or scows) to transport the dredged material under the Coast Highway Bridge to a scow marshelling area in Newport Bay (location to be determined). Filled scows would be exchanged for empty scows at this point and ocean- going tugboats would transport the material to the approved ocean disposal site. (3) Combined Landfill and Oeean Disposal — If approval of an ocean site is secured, some combination of the two alternative disposal sites methods would be likely. Therefore, this option would include some truck loads (1,250 to 3,000 is estimated) and some barge (or scow) loads (8 to 5o is estimated). Following the dredge operation, construction of the marina and guide piles is expected to take approximately 5 months. The marina dock framing system will. be composed of preserved wood framing members connected by galvanized metal angles, bent plates, and through -bolts. Framing for the slip fingers will include torsion bars to resist potentially excessive twist caused by tidal action and currents at and near the Coast Highway Bridge. Guide piles shall be designed to support the floating dock system, and shall include composite pre -stressed concrete piles with steel driving tip, or round steel pipe piles. Piles will be cathodically protected. Depending on the bay bottom conditions, piles will be either jetted into place or driven into place using a barge -mounted diesel pile driver. Dock flotation will be composed of a combination of foam -filled concrete and rotationally molded polyethylene plastic pontoons —both methods being widely used in Newport Bay. Landside improvements, such as the restrooms, showers, and storage facilities, will be constructed over a 2- to 3-month period concurrent with the marina construction. Paving of the parking areas and landscaping will occur during the final phase. Utilities serving the proposed marina will include one sewage pump -out station -- centrally located on the docks. Sewage will be pumped to a City of Newport Beach sewer line in Dover Drive. Water will be supplied to the marina for both domestic uses and fire protection. These systems will be designed to meet City of Newport Beach Fire Department requirements. 1 I u I II 4 JB%/0040007B1 Pr:�� r, , •, V , y r S'' ♦ Fr�� � ,• �O� � /' Y"F�,1 1>;'('i �•a",/,i•�'f"*yM`.++�f>�'l 'fi.6%� ♦ �V`.� j(j�� Coyote Canyon Landfill ,OOQ /°�� �':/; i'--�� �,T\�,��1�1��1"' �'"•�=^- - Disposal Site (A4ernacive#I) yam^//\���� rxJ_tttrrl' ^-��, i• �Z>.\ r }\_ Project Site A4k-� o PP /i y)' (r�r. / jjfl4ti . w l /� '$�'I1„ �� `�\/�/I:r.✓;,>j/ >7>y �``►ChSi�fr; � i �N\��i 1 a � • �L Y ,4 L1�Mr ��j�'�,a-42Q, �Q•", �. � -£ f., rrtii .-- . • -e : ! y'�m _t a LC�, n aFie.�.jIPI t.• ..

Does the project have the potential to degrade ' the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population , to drop below self sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate t important examples of the major periods of X California history or prehistory2 _ — ' .6_ ' LI F L I 1 1 1 1 Yes Maybe No b. Does the project have the potential to achieve short-term, to the disadvantage of long-term, environmental goals? (A short-term impact on the environment is one which occurs in a rela- tively brief, definitive period of time while long-term impacts will endure well into the future.) X C. Does the project have impacts which are individually limited, but cumulatively con- siderable? (A project may impact on two or more separate resources where the impact on each resource is relatively small, but where the effect of the total of those impacts on the environment is significant.) X d. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?_ X III. Discussion of Environmental Evaluation (Narrative description of environmental impacts.) (See Attachment B) IV. Determination On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION WILL BE PREPARED. I find that although the proposed project could have a signif- icant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE DECLARATION WILL BE PREPARED. Q ' I find the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. Date Signature ' C\PLT\EIRLIST.FRM For z.e ' - 7 1 ' ATTACHMENT B ADDITIONAL INFORMATION CASTAWAYS MARINA ENVIRONMENTAL INFORMATION FORM ' The following discussions provide clarification and additional supporting information ' for those items checked on the Environmental Information Form and Initial Study/Environmental Checklist Form for the proposed Castaways Marina. The reader is requested to refer to the numbering sequence on the forms which ' correspond to the numbered items in the left column of this document. ' Environmental Information Form Page 2 Item 21: Removal of approximately 80,000 cubic yards of dry fill ' and bay material will be completed in order to provide the main boat basin and access channel. Item 22: The existing vacant land will be altered to a 125-slip ' marina; public viewing areas are also planned around the marina. ' Item 23: The existing vacant land, which supports ruderal vegetation, will be altered to an -open water marina. ' Item 24: No significant volumes of waste materials are expected. Item 25: During construction some dust could be generated; dredging of bay sediments could result in short-term increases in odors. Item 26: The marina basin will increase the surface area of Upper Newport Bay by approximately 2.5 acres. Preliminary sediment and water quality studies of the dredge area indicate no significant pollutant levels are present. Drainage patterns will be altered due to the reduction of ' land at the site. ' Item 27: Construction activities will result in short-term increases in noise and vibration levels over existing condi*ions; long-term noise from the operation of additional boats may also result in minor noise increases. ' Item 28: The Castaways Marina is proposed for an area that was created from dredged material. Slopes are less than 10 percent. 1 I JB%/0640007B1 Item 28: No fuel facilities or hazardous materials will be present at the marina. Item 30: No substantial Increases in municipal services are , expected although security, fire protection and utilities will be required. ' Item 31: No substantial increases in fuel usage are expected; motorized boats will utilize fuel obtained elsewhere in Newport Bay. Construction activities will use minor amounts of fuel. Item 32: The proposed marina (125 slips) is a single project and is not related to any others. ' Environmental Checklist Form Page 1 Earth Item 1(a): No unstable earth conditions are known to exist in the , project area; bluffs to the north of the site will be secured by low retaining walls along the marina property boundary. Rip -rap will be placed at corners of the , marina basin to reduce erosion. Item l(b): Removal of approximately 80,000 cubic yards of dry and wet sediment is proposed. In addition, if any dredged , material is to be disposed of at the county 1'andfill, then a dirt road will be graded from the Lower Castaways site to the Upper Castaways site to provide an egress route to 16th Street for the haul trucks Item 1(c): Existing flat fill areas will be removed through dredging; possible disposal of the dredge material at the Coyote ' Canyon Landfill would alter the topography at the landfill. ' Item l(d): No unique geological features (bluffs, etc.) will be altered. ' Item 1(e): Soil erosion from Lower Castaways may increase during the construction/dredging phase. In addition, if a dirt road Is required up to the Upper Castaways site, erosion may increase along this road surface during its use. ' Potential short-term increases in erosion from the dredge area (Lower Castaways) will be reduced through the use of bulkheads and retainer walls. In the long-term, ' reduced erosion of the site will result due to the removal or paving of erosive soils. 2 1 JB%/0640007131 1 LI t 1 Item 1(f): Increased water depths within the basin and along the detached slip pier could result in increased flows within Newport Bay. Decreased siltation into the Bay is expected due to the removal of the existing fill material. Possible disposal of dredged material into the ocean would modify a portion of the ocean bed. Item It): No increases in exposure to geologic hazards are expected as no onshore amenities are proposed at the marina. Page 2. Air Item 2(a): A short-term increase in air pollutant emissions from construction equipment would occur during the dredging and dredged material disposal activities. Item 2(b): Dredging of bay sediments could result in short-term increases in odors. Item 2(c):' The proposed marina will not alter existing climatic conditions. Water Item 3(a): Dredging of the main basin and channel and possible disposal of dredged material nto the ocean may alter local current flow within tt e• affected• areas; ongoing engineering studies will analyze these potential changes. Item 3(b): Reduced absorption and surface runoff will result from the removal of existing fill material; reduced siltation into the Bay is also expected. Item 3(c): No significant alteration of flood waters is expected from the dredged basin. Item 3(d): An additional 2.5 acres of surface water in Newport Bay is expected from dredging of the main basin. Item 3(e): Dewatering of the wet materials for possible landfill' disposal would result in discharge into the Bay. Sediment and water chemistry analyses completed to date indicate no significant water quality impacts in Upper Newport Bay are likely. Potential effects of possible ocean disposal of dredged materials are under study. Approval of this alternative by the U.S. Environmental Protection Agency and U.S. Army Corps of Engineers will be dependent on study results and a finding by these agencies that no significant impacts to water quality would occur. 3 JBX/0640007B1 Item 3(f): Ground water flow is not expected to be altered by proposed activities. Item 3(g): Freshwater sources (groundwater) are distant from the proposed marina; saltwater Intrusion is not expected to result from the increased area of the Bay. D Item 3(h): Water for boat washdown and drinking sources will be available at the marina. No significant increases in usage ' Is expected. Item 30): The marina will be exposed to flooding or tidal waves, similar to other facilities within the Bay. The exposure is expected to be minor ,and ample warning of such occurrences from existing information sources is expected to reduce the potential for significant impact. Page 3 Plant Life Item 4(a): Removal of existing terrestrial or benthic vegetation within the marina site/dredge area will occur; however, no significant changes in the diversity of plant species in the area are expected. Potential effects at the possible ocean disposal site are currently under study. Item 4(b): Biological surveys of the marina site and Upper Castaways site have been conducted; no unique, rare, or endangered terrestrial or benthic• plant species are known to exist at these sites. Item 4(c): Landscape vegetation around the marina will differ from existing plants. Effects at the possible ocean disposal site are currently under study. Item 4(d): No agricultural activities currently exist within either the marina or dredge disposal sites. Animal Life Item 5(a): Loss of existing terrestrial and benthic habitats at the marina site could result in reduction of existing animal life; however, no significant changes in diversity of species is expected. Potential effects at the possible ocean disposal site are currently under study. Item 5(b): No unique, rare, or endangered terrestrial or benthic animal species are known to occur at the marina site or Upper Castaways site, although four sensitive bird species feed or nest in the upper reaches of Upper Newport Bay. J I 4 dB%/0640007B1 Item 5(c): No new animal species are expected to inhabit the area; an increased water area could provide additional habitat ' for bay fishes. Potential, effects at the ocean disposal site are under study. ' Item 5(d): No significant deterioration of existing habitats is expected. Alteration of the marina site will reduce the non -unique ruderal habitats on the Lower Castaways site. Increased water areas will increase the habitat for aquatic organisms. Potential impacts at the possible ocean disposal site are under study. Approval of this alternative by the U.S. EPA and U.S. Army Corps of ' Engineers will be dependent on study results and a finding by these agencies that no significant deterioration to habitat would result. Noise Item 6(a): Short-term, construction -related noise increases could ' result from dredging, disposal (hauling of dredged material) and pile -driving activities. ' Item 6(b): No significant increases in noise levels to residential areas are expected due to the distance from the site and buffers between source and receptors. Light and Glare Item 7: Possible increases in lighting around the marina is ' expected to be minor and localized. Land Use Item 8: The marina site is currently unoccupied and is zoned for ' marine recreational and commercial uses, thus no conflicts with existing or planned land uses are expected. ' Page 4 Natural Resources Item 9(a): No significant increase in the use of natural resources is expected from the proposed project. Fuel will not be ' available at the site and the increased boat slips and resulting boat usage is expected to be minor. Risk of Upset Item 10(a): Accidents related to boat traffic could result in the ' release of minor amounts of fuel; however, no refueling services will be available at the marina and no hazardous materials will be stored. The chance of significant boat taccidents occurring is considered unlikely. n JBX/0640007B1 I Item 10(b): No interference with evacuation/response plans is expected. The marina is "self-contained" and is not expected to impact the orderly evacuation of the area. Population Item 11(a): No increase in population is expected from the project. Mooring facilities will be limited to small vessels and no food, fuel or service facilities are planned for the marina. Construction crews are expected to be from local areas. Housing Item 12: No additional housing is required for construction or operation personnel. Transportation/Circulation Item 13(a): A traffic study (1% Traffic Analysis) conducted for the proposed marina concluded that this project will not generate a significant amount of traffic. during its operation and that most traffic would be generated during non -peak traffic periods. However, truck traffic generated during construction (especially for possible hauling of .dredged material to the Coyote Canyon Landfill) may reach potentially significant levels for a short period of time. I I P Item 13(b): The proposed number of parking areas is greater than the ' minimum parking requirements for the marina. Item 13(c): During the dredged material disposal and construction phases, truck traffic along Dover Drive, and other City of , Newport Beach and regional roadways, may impact existing levels of service. Item 13(d): No long-term alteration of traffic patterns is anticipated. ' Item 13(f): Increased hazards to bicycle, motor vehicle or pedestrian traffic are not anticipated. Further analysis and locations of cross walks and/or turning lanes will be completed prior to project initiation. Public Services Item 14(a): Additional service for fire protection will be required, although onsite fire fighting equipment (e.g. hydrants, fire extinguishers) will be included in final design. Item 14(b): Increased patrolling of the area will be required. I JBX/0640007131 J tItem 14(c): No additional schools will be required since no additional population will be generated. ' Item 14(d): The facility will increase available recreation facilities including public viewing areas and recreational boat slips. No additional recreational facilities within the city ' will be required to support this facility. Item 14(e): Responsibility for maintenance of the facilities will be ' determined prior to initiation of the project. Item 14(f): No other government services would be required by the ' marina. Page 5 Energy ' Item 15(a&b): No substantial increase in energy (fuel or electricity) is required, as no substantial public facilities or fuel stations are planned for the marina. ' Utilities Item 16(a-f): With the exception of the proposed sewage pumpout ' station, utilities for the marina will be connected to existing facilities. Removal of grey water and bilge waste from the pumpout station and sanitary waste from ' the restrooms will require hookup to existing facilities. Human Health ' Item 17(a&b): No increase in health hazards are expected from the marina. Existing boat traffic within the Bay may be locally impacted by the expected insignificant increase in ' the chance for a boating accident. Page 6 Aesthetics Item 18: The aesthetics of the site are expected to be improved over the existing vacant land with ruderal plants. Increased viewing area from the marina will provide ' increase opportunities to observe Upper Newport Bay. Recreation ' Item 19: Recreational opportunities, including access to a currently restricted area, are expected to significantly ' increase with the marina providing opportunities for recreational boating. I 1 7 JBX/0640007131 I Cultural Resources Item 20(a-d): The northernmost end of the proposed access (haul) road may infringe on a portion of an archaeological site on the Upper Castaways site. Test excavation will determine the significance of any potential impacts to this site. The proposed project would not impact any known religious or sacred uses of the study area. Mandatory Findings of Significance Item 21(a): Development of the marina, dredging and disposal of dredged materials will habitats. The significance of these study. I I of bay sediments, ' alter the existing effects is under Item 21(b): No long-term detrimental impacts are anticipated from , the proposed project. Alteration of existing, non -unique habitats will result In long-term increases in available ' recreational facilities and water -related habitat for aquatic species. Item 21(e): With the exception of potentially minor traffic increases, ' no cumulative impacts are currently anticipated. Item 21(d): No substantial, unmitigable impacts are expected from construction and/or operation of the marina. Increases in public access, aquatic habitat*. recreational facilities, and aesthetic quality balance the short-term construction impacts discussed above.

A description of existing terrestrial and aquatic biological resources and habitats within and adjacent to the project area. This description should include amounts of intertidal, subtidal and terrestrial habitat types and major forms of associated flora and fauna within the project and adjacent areas including the proposed dredge disposal site. Areas of particular interest are intertidal mud flats and shallow subtidal areas which may be lost or severely degraded as a result of dredging and dock construction activities. Also, the relationship of the proposed project to the Departments Upper Newport Bay Ecological Reserve needs to be included. 2. A description of existing water quality conditions including, but not necessarily limited to, circulation and tidal flushing rates, oil and grease levels, presence of heavy metals such as lead, zinc, copper, etc. within sediments and water column and existing problems related to surface runoff. 3. Impacts, both short and long term as well as cumulative, to biological resources and habitats as a result of project implementation. We are especially concerned with impacts which would result from: a) Loss of intertidal and subtidal habitats and associated resources as a result of dredging and possible slope protection. b) Increased boating activities, especially power boats which could result in an increase in the rate off small oil spills in the upper bay. 2— c) Increased vessel activities within Upper Newport Bay could result c) Increased vessel activities within Upper Newport Bay could result in impacts to the Ecological Reserve. The reserve provides critical habitat for several endangered species. These species include the California least tera, light—footed clapper rail, California black rail and Belding�s Savannah sparrow. 4. Mitigation -measures which will either offset or minimize identified , impacts. Measures such as directing surface runoff away from bay waters, providing pumpout facilities, minimizing loss of productive intertidal and subtidal habitats as well as maintaining the productivity of existing habitats and other appropriate measures to , offset impacts should be included in the document. 5. Alternatives, including the no project alternative, to the proposed project should also be included in the document. Should you have any questions, please contact Richard Nitsos, Environmental Services Division, 330 Golden Shore, Suite 50, Long Beach, California 90802. The phone number is (213) 590-5174.

Temple: Jr•;- C . r. September 15, 1988 SCH,#88081016: Castaways Marina The Department of Boating and Waterways is not a regulatory agency and does not issue any permits- However, we do review and may comment upon U. S. Corps of Engineer public notices for proposed projects and environmental documents which are submitted to us by the State Clearinghouse. For review purposes, the Department's interests lie in the following areas: 1. Potential for Navigation Hazards - Tb what extent might the Proposed project affect safe navigation in California's waterways 2. Beach erosion - Will the project affect the stability of coastal or bay beaches? Float control projects, including darns and reservoirs, can have an impact on the transport of sand from rivers to coastal beaches. All coastal projects that intrude into the ocean are analyzed by Department coastal engineers. 3. Boatinq and pqktulg Facilities - To what extent might the proposed project affect existing or planned small craft harbors or launchiW facilities? To what extent might recreational boating activities be affected? 4. Public Trust - Placement of permanent residences or other facilities that would not be open to the public is analyzed by the Department in regard to public trust. The public trust doctrine holds that public lands and waterways are to be used for public benefit. If you have further questions, please contact Barbara Fierbow at (916) 445-6281.

SANDERS DWIGHT E. SANDERS, Chief' Division of Research and Planning , DES:maa ' cc: OPR Linda Martinez Eddie Powers, CA Recreation Company r r.. GENERAL INFORMATION REGARDING APPLICATIONS ' FOR EXTRACTIVE DEVELOPMENT OF STATE LANDS rnnn as.as rsrau ' The State Lands Commission his jurisdiction and control over public lands belonging to the State of California and , any mineral Interest therein. Generally, these lands include all ungranted tidelands and submerged ►ands, beds of navigable rivers, streams, takes, bays, estuaries, inlets and straits, school lauds, swamp and overflowed lands, and some proprietary lands. The Extractive Development Program Division of the Sate Lands Commission administer the development of all mineral (geothermal, oil, gas and other minerals) resources contained in such lands. All applications to develop lands lot mineral (goothernsaf, on, gaa and other minerals) extraction are subject to an ' extensive review and analysis by the staff of the Extrsctiw Devefopmerst Program Division prior to approval or rejection by the State Lands Commission. Each project or activity frteolek,g dse iuuse e s of a lease, permit or other entitlement for use must be reviewed for cempliwm with a vwiety,,of stattates, rides and regutetions and land management policies of the Commission. To list the specifics for every project is not possible due to the many variables involved: howeve certain bask factors apply to all t►aroa lsollo The following outlines the general steps icroolved in developing State Inds for mineral extraction. ;}li LAND AND/OR.MtNERAL OWNERSHIP ' Before offering lands for mineral development, the Title Unit of the State LandeCotrsrniaalon reviews the Information In its files and that submitted by the applicant to determine the extent of the SbWs Interest, In cases of complex Isnd arid'mineral ownership, the applicant may be requested to provide a title report or chain of title guarantee. , LEASING POLICIES AND PROCEDURES Any applicant who meets the qualifications of section 6801 of tM Public Rasoureea Code (P. R.C.) and desiring to develop any of the lands owned by the Sate, or in which the Sate may have an interest, and which are under the ' jurisdiction of the Commission, may make application to the Commission. The application shall be accompanied by a filing and processing fee. All protpeetive applicants should be aware that some lands or portions of land may rat be available for mineral development or that certain conditions may be imposed before any development is allowed. The State Lands Commission manages the State lands for multiple use. Should the State Lands Commission deter- mine that the development of the particular resource will not interfere with the purpose for which the lands were acquired or are managed, the applicant will be informed of such determination and any conditions by which it may develop the resource. STATUTORY COMPLIANCE Any qualified person, firm or corporation desiring to develop any lands owned by the State or Under its jurisdiction, may make application to the Commission and shall describe the lands sought to be leased by legal subdivisions or by any other method as the Commission may prescribe. Division S. Part 2 of the P.R.C. describes in detail the , Commission's statutory responsibilities with respect to the leasing of public lands. Such development is briefly described in the atta hments tar each specific resource category: geothermal, oil and gar, and other minerals. CALIFORNIA ENVIRONMENTAL QUALITY ACT (.CEOA) , The issuance of a lent, permit or other entitlement (or use requires legal review fbr compliance with the California Environmental Quality Act iCEOAL No development project will be sporoved until compliance With CEOA has been achieved (P.R.C. sections 210DO et sea.). Additionally, if the eooliatan involves 'Significant Lands" pursuant to P R C sermons 6370 et sail conswinicy of the proposed project with the identified values must also be deter. mmou tr••nurih the CEOA pruc•ist 'Ca:•innna Atimrrstrat.vs Code (C.A.0 - Title 2.

I POOR QUALITY ORIGINAL (S) LI It,a project is not exempt from CEOA, the staff will conduct an Initial Study to determine whether a project may have a significant effect on the environment, unless it is determined that the project will clearly have a significant effect. The Initial Study is circulated for approximately two (2) weeks to all appropriate permitting agencies and interested parties for public review and comment. Based on the responses received, a determination is made as to whether a Negative Declaration or Environmental Impact Report (EIR) is required. A Negative Declaration is the simpler of the two types of documents and requires less processing time than an EIR. ' Generally, it consists of the Initial Study accompanied by a determination that the project will not have a significant effect on the environment and may include mitigation meawres, It is circulated for thirty 130) days to appropriate agencies and interested parties. Review by involved State agencies is provided through Use State Clearinghouse, If no significant environmental effects are identified, the Commission eonsidars.the Negative bec(antion together with any comments received, and certifies and approves or disapproves )L An EIR is required in instances where responses to the Initial Study re8eet Concam that the project may., 1 a when it has been determined that the project will. have a nment.Proposed significant affect On the environment. Usually a third party consultant will be hired by the staff to prepare the EIR. The applieeht wig be required to cover the cost of . the conaukant prior to the preparation of the EIR. Part ehaperiarnee has shownthat EIR eats wry eoraiderablytfrare a bat_ �4C00 to an amountexceeding 5100,000. The applicant must deposit an amount specified by the staff within tveiei yaone (21) days after written notice that an EIR is required..T)he staff will not solicit retltsests forpropoeais from )ndependeM Consultants until the deposit is provided by the app(ianL in addition. if the cost for the preparation of the EIR exceeds the amount deposits, the amount of excess costs I be deposited within fifteen 11% days after eivit en-rh, 1, is given. (Any txhexpencied portion of -.the deposit will be refunded to the applicant after the EIR is determined by the Commission to be ' adequate.) Should the aPPfiont fail to deposit the requested eats, the application may be cancelled without further notice. In most instances, the yreparation of an EIR takes from six (6) to nine 191 months. The Draft EIR is circulated I for forty-five (45) days to agencies and individuals concerned about the project. The State Clearinghouse provides for circulation to State agencies. During the 45•day review period, a public hearing may be held. Comments and recommendations received and significant environmental points raised in the review and consultation process are ' responded to. in a Final EIR. This document is then circulated for an additional fifteen (15) days to those agencies and persons who commented on the Draft EIR. After the review period has ended, the Final EIR, including any mitigation measures, is presented to the Commission for certification and approval or disapproval. ' TIME CONSTRAINTS/COMPLETENESS OF APPLICATION Most leases, permits or other entitlements for use require approvals from other public agencies. Usually the State Lands Commission is the Lead Agency or the public agency having the principal responsibility for carrying out or ' approving a project when the project occurs solely on State lands. When an EIR is prepared, such responsibility requires the Commission to approve or disapprove a development project within one 11) year from the date on which an application requesting approval of the project has been received and accepted as complete by the staff of the Commission. Where a Negative Declaration is prepared or if the project is exempt .from CEOA, the development project shall be approved or disapproved, within six (6) months from the date on which an application requesting approval has been received and accepted as complete by the staff. ' An additional time period of up to ninety (90) days may be allowed if mutually agreed to by the staff and the applicant. Not later than thirty (301 ealenda• days after the Commission receives an application for a development project. the staff .vi!I notify the applicant in writino whether the application is complete. In the event the application is tlrtermsrve ^ot -o :.v r•Osnnf2te the :raft will specify what additional information is required. Upon receipt of the asl:ht.n^,v ,—.;ter•:s• •ho- stall -ill resound .vith;n shirty (30) days as to whether the application is complete.

The adequate completion of Parts t — V of the attached .. Application Form shall constitute a complete application. The following are some of the circumstances that may cause the Commission to deny a project- 1. Failure of applicant to furnish requested additional information: 2. Environmental caaidarations: 3. Failtwe to meet any statutory requirements: 4. Fsiluie to submit rtgtsteted fees or deposit for EIR, S. Failure to eeerelade negotiations or to execute documents; S.

BOX 4048 SANTA ANA, CA 927024048 FILE NCL 88-120 TELEPHONE (714) W4W The above referenced item is a Notice of Preparation (NOP) for Castaways Marina. The project would construct a 125-slip marina on approximately 4.0 acres of land and open-Vater areas located at the northwestern portion of the Newport Backbay. It will also include a restroom/shower building and 108 parking spaces. The County of Orange has reviewed the NOP resulting in the following comments: AIR QUA=: The air quality analysis for this project should be prepared in accordance with the techniques recommended by the California Air Resources Board and the South Coast Air Quality Management District. BMIWATS: The Master Plan of Countyvide Bikeways (MPCB) depicts a Class III (on -road, signs only) bikeway along Dover Drive. However, this bikevay is presently striped as a Class II (on -road, striped lanes) bikeway. In addition to maintaining this bikeway, the project proponent should establish lockers, showers and racks located at a central destination point to be utilized by commuting bicyclists expected to be employed at the commercial site. Bicycle facilities are mitigation measures to reduce traffic congestion, vehicular noise and air pollution by encouraging the use of bicycles as an alternative mode of transportation. Such measures would be in compliance with SCAOMD's Regulation %V and the Air Quality Management Plan 1982 Revision, adopted by Orange County Board of Supervisors on September 27, 1983. r r r r i 11 r r i r i r r Patricia Temple Page 2 HAZARDOUS WASTE DISPOSAL: ' The disposal of waste oil, paint thinner, diesel fuel and similar flammable liquids in specially provided containers is strongly encouraged. There should ' be no direct charge to boat owners for this service to minimize illegal disposal practices. CLEANING/MAINTENANCE WASTES: ' .Wastes generated by cleaning and maintaining boats (paint scrappings, detergents, etc.) should be routed to a separator and the water phase should ' then flow to the sanitary sewer system. The wastes should not flow to the Upper Bay. ' Thank you for the opportunity to respond to the NOP. Please send three copies of the Draft EIR to Cathy Nowak at the above address.

Box 1768 Newport Beach, California 92659-1768 tDear Ms. Temple: We have reviewed the Notice of Preparation of a Draft Environmental Impact Report (DEIR) for the Castaways Marina, dated February 22, 1990. The notice requests information about our responsibilities involving the proposed project. ' Our responsibilities include investigation, design, operation and maintenance of water resource projects, including preparation ' of environmental guidelines in the fields of flood control, navigation and shore protection. We are responsible also for administration of laws and ' regulations against pollution of the waters of the United States. We believe the forthcoming document should address the above - listed responsibilities. ' Work in waters of the United States might require a permit under Section 404 of the Clean Water Act or Section 10 of the Rivers and Harbors Act. Please give our Regulatory.Branch. ' documentation that clearly describes the area and extent of any proposed work in watercourses and adjacent wetlands to help us make that determination. ' If the proposed project involves any Federal assistance through funding or permits, compliance with Section 106 of the National Historic Preservation Act of 1966, as amended (16 U.S.C. ' 470f) and implementing regulations, 36 CFR 800, will be required. Please feel free to contact this office for any data that can help you prepare the projected document.

As we previously discussed, our comments/concerns regarding this project include the following: - The addition of 118 boat slips in the proposed marina location upstream of the Pacific Coast Highway Bridge is likely to have little impact on harbor traffic. This is not a significant increase to the total number of slips in the harbor. - Dredging/barge operations are likely to have adverse impacts on the numerous recreational and commercial vessels which transit the harbor's narrow channel. For this reason, the EIR should contain a workable traffic management scheme for any alternative that will involve barges working in the harbor. This scheme should include such measures as the establishment of traffic lanes, operating restrictions on barges, private and commercial vessels, or both, limiting transit times, and an educational effort for the boating public. If you have any questions about our comments or concerns, please feel free to contact me at the number shown above. Sincerely, N. S.

The requirements used presently by SCAG are revised as shown below to provide for the adoption of the Growth Management Plan, Regional Mobility Plan, and Air Quality Management Plan. [Revised on November 1,1989] if any proposed projects) will or coWd cause environmental impacts, such impacts must be consistent with the forecasts included in GrowthManagementPlan and Regional Mobility Plan (approved in February 1989) and the Air Quality Management Plan (approved in March 1989). The relationships of the forecasts and policies mentioned above must be addressed and evaluated wherever applicable. Therefore, all of the documents listed above and other such studies and reports should address the issues below. (Not all issues will apply to every project) 1. What are the impacts of the proposed project on population, employment, and housing? Give the growth forecast for each phase of the project, if phased. 2. Are the growth management goals and policies complied with? 3. Are the JobstHousing Balance performance goals being met? 4. Is housing availability discussed in terms of the income and wage levels of the local workforce? S. What will be the cumulative impacts of the project in the subregion? How is this related to the Growth Management Plan forecast at theexpected date ofproject completion or phase completion? 6. Are the provisions of the Air Quality Management Plan implemented at the local level and within the subregion? What are the air quality impacts of the project? Are they being addressed? 7. For any project with transportation corridor -level impacts, what are the long-term Impacts? 8. What assumptions are used in estimating the total trips generated by the project? 9. What are the related vehicular emissions? F I I U t ' 10. What is the annual impact on total trips generated by this project? 11. Discuss the transportation demand -management program chosen for the project. Will mass ' transit, ridesharing, and other trip -reduction strategies be promoted? Quantify the effects of each component of these programs. Provide an implementation schedule for each component. Identify the person or agency responsible for monitoring and adminstering the program. ' Who will operate the program? How, will the program be funded? ' 12. Does the project impact a highway, either directly or indirectly? Does it include a highway in a mitigation measure? If so: The document must state where the project includes High Occupancy Vehicles (HOV), transitway, and/ or mixed -flow improvements; It must state how mitigation measures will promote the use of HOVs, transitway, and/or mixed -flow improvement: It must state whether the highway improvement is included in the Caltrans District Service Management Plan. ' 13. Transportation improvements/projects must adhere to the following criteria: The impact of the overall project on air quality in the long term must be analyzed on a transportation corridor level, even if the project is phased or incrementally developed ' The impact of the project on air quality must be compared with the impacts of the project alternatives, on a transportation corridor level. The alternatives must also be compared with each other. The demand -management strategies, HOV improvements, and transit are required to be evaluated as ' alternatives (and as mitigation measures if necessary). 14. AU PROJECTS MUST STATE THE FOLLOWLNG: ' o Whether they are included in the Regional Transportation Improvement Program; o Whether they are consistent with local planning documents; o Whether they are identified as constrained or unconstrained in the Regional Mobility ' Plan; o Whether they are consistent with the specific policy elements of the Regional Mobility Plan, Section IV.

The project would develop 125 boat slips and would require dredging and disposal of material (either to landfill or ocean disposal site). The project site is at Newport ' Bay, northeast corner of Pacific Coast Highway and Dover Drive. The County of Orange has reviewed the NOP resulting in the following comments: BICYCLE TRAILS ' The Master Plan of Countywide Bikeways (MPCB) depicts a Class I (off -road) bicycle trail (Route 55: Back Bay Vater Level Trail) passing through, or ' adjacent to, the project site. The EIR should address this regional trail facility that will ultimately provide a linkage between Upper Newport Bay Regional Park and the San Diego Creek Trail, and lower Newport Bay and the ' Pacific Coast Highway Traii4 AIR QUALITY The air quality analysis for this project should be prepared in accordance ' with the techniques recommended by the California Air Resources Board and the South Coast Air Quality Management District. , WATER RESOURCES The following comments are offered: , I. Mitigation of grading and excavation should be implemented to minimize the transport of sediment to Newport Bay. 2: Precautions should be taken to assure the operation of this Marina will have minimal impact on the water quality of Newport Bay especially the natural habitats of the Upper Newport Bay Ecological Reserve. Best , Management Practices (BMP's) should be implemented as mitigation for ' Fhr:R 05 196 07124 Uiz - rmw, w-n r.Z. n L n r" L 1 I Ms. Patricia Temple Page 2 runoff of vehicular residues (fluids, fuels, lubricants, heavy metals) from the parking lot as well as nutrients; pesticides and herbicides from landscape maintenance. 3. The disposal of waste oil, paint thinner, diesel fuel and similar flammable liquids in specially provided containers is strongly encouraged. There should be no direct charge for this service to minimize illegal disposal practices. 4. Wastes generated by cleaning and maintaining boats (paint scrappings, detergents, etc.) should be routed to a separator and the water phase should then flow to the sanitary sewer system. The wastes should not flow to Newport Bay. 5. It is assumed that the dredged material, if disposed of at the now -closed Coyote Canyon Landfill, will be used as final cover material. This material must meet engineering standards for such application (Title 23, Subchapter 15 of the California Administration Code). Thank you for the opportunity to respond to the NOP.

An existing stop is located at: , - Northbound Dover Drive/Farside Coast Highway. • In order to ensure accessibility to the available transit services for ' employees and patrons of this development, the following transit amenities should be incorporated into this project: - A bus turnout, if determined by the City Traffic Engineer to be ' necessary based on roadway cross section, travel volumes or speeds, should be provided at this stop location. ' - The area adjacent to this stop should include a paved passenger waiting area complete with a bus shelter and bench. - A paved, lighted and handicapped accessible pedestrian accessway , should be provided between this stop and the project buildings. - A concrete bus pad sufficient to support the weight of a bus (see , OCTDrs Design Guidelines for Bus Facilities) may have to be provided at this transit stop. This would be necessary assuming the material used to construct Dover Drive would be insufficient to support' ' continued transit use of the bus stop.

' Our specific environmental concerns are as follows: I. We are particularly concerned about the traffic problem that will be generated as a result of the marina project, especially those people who are travelling southbound down Dover Drive as they try to enter the marina. Because there is no left turn entrance or U-turn available at Dover and Pacific Coast Highway, we feel most people will try and use the Bayshores entrance as a U-turn area. This will undoubtedly cause congestion to homeowners and visitors of Bayshores. This problem will be compounded by, the fact that the signal at Dover and Pacific Coast Highway is a rather "short light" for Bayshores ingress and egress. 2. We are concerned about the dredging operation as it relates to changes to our main beach area and waterfront homes; especially in connection with erosion, silt deposits, or any other significant bay changes caused by the dredged areas. 3. We would respectfully request that the developers/barge company nit allow their barges to be moored directly in front of our main beach area, which is usually the case when dredging operations are in process in the back bay area. I I F `BAYSHORES COMMUNITY ASSOCIATION 2889 Bayahore Drive, Newport Beach, California 92663 Ms. Patricia Temple March 26, 1990 Page 2 We look forward to a response to our questions and concerns either from California Recreation or the City of Newport Beach. We would also appreciate being notified of any important meetings or public hearings in regards to this project. Very truly yours, BAYSSHORES COZKMTY ASSOCIATION Kevin M. Green Vice -President work - (714) 833-7657 home - (714) 631-4465 cc: Joleene Hanks Christine Padilla 1 26 March 1990 TO: Mayor, and Members of the City Council 1 Planning Commission Patricia Temple, Principal Planner 3300 Newport Boulevard , Newport Beach, CA 92663 FROM: CEQAC's Subcommittee on EIRs Your Honors: 1 On 19 March 1990 our subcommittee met to study the Notice of Preparation of a Draft Environmental Impact Report for the Castaways , Marina Project to be located in the Upper Newport Bay at the northeast corner of Pacific Coast Highway and Dover Drive. , As we looked over the material we wondered, where is the initial study which we did not receive? Furthermore, if the process is starting over again, should everyone concerned receive the opportunity to comment? , Should a better and larger map (which provides a better perspective of the projects intrusion into the channel of navigation between the upper and - lower bays) be included in the study materials? Should the following environmental groups and governmental agencies be asked to comment on the proposals? The Sierra Club, the Friends of the Back Bay, the Audubon 1 Society, California Fish and Game, The U.S. Army Corps of Engineers, the California Coastal Commission, CaiTrans, Newport's Harbor Water Quality Committee, scouting organizations? These are groups which we think may have particular interests and/or scientific and engineering expertise to help ensure (1) that the public's access to, views of, and navigation of the bay are not diminished by private projects; (2) that the Bay's water 1 quality and natural environment for birds and marine species are protected; (3) that the integrity of the coastal bluffs are maintained. Our sub -committee does not believe the information would be adequate 1 for preparation of a complete EIR without comment from these environmental and scouting groups, recreational users (i.e., bird watchers, canoeists, etc.) of the Back Bay and governmental '& . B concerned with protection of the bluffs, fish and game, t , ,1164T �dsdY navigational routes and safety. CITY of NrWPORT BEAC, Generally, our concerns fell into two groups: Short-term impAIRF "Op0 PM 1 would result from the construction of the marina and Ion lni*f(giB14151s which would result after the marina is placed in operation. I The fragile nature of the Back Bay requires careful scrutiny of long-term ' effects on the environment to ensure that it is a safe habitat .for endangered species and a natural resource available to all residents. Some of our long-term environmental concerns include the following: storage of an estimated minimum of 12,500 gallons of fuel on the boats (125 X 100 gallons each); leaching of toxic boat -bottom paints into the water; the potential for discharge of human wastes from the boats; the potential for water -borne toxins from the scrub -down of boats; the problem of increased traffic and its impact (particularly on the safety of ' school children traversing the PCH-Dover Shores intersection by bicycle); protection of the bluffs above the marina; the impact of a narrowed channel for small sailing boats, row boats, and power boats not moored at ' the project; the elimination of public access to or use of what is now public open water (i.e., the 4 acres of Bay which will be for use by 125 ' individuals leasing slips); deterioration of air quality in the adjacent neighborhoods. Brown pelicans and other birds which are known to roost in the area and to fish in the channel between the bays may be forced' to ' leave this area of the Bay. Frequent dredging to maintain adequate depths for large boats may .affect siltation patterns and may alter the water quality outside the marina. Although not within Newport Beach, the ' dumping of the salt -laden material at Coyote Canyon could poison the earth to vegetation for many years until the salts percolate below the root zone. ' To mitigate the loss of 4 acres of open, public waterways, the developer ' should provide 4 acres of parkland elsewhere in the City. Enclosed are more detailed comments about the "Notice of the Revised NOP" S' cerely, C�Ctr7nn Hollander r I I I Page 1, Castaways project , GENERAL COMMENTS: Regarding jurisdictions we wondered which lead agencies for government are concerned. Does the Marina represent an example of public property being converted to private uses which block the public's present view of the water and the public's ability at present to traverse the water way itself? Which agencies will ensure that the public has access to the Bay water and its surface? Has the Coastal Commission been asked to comment- on the coastal bluffs here and the project's impact on their integrity? Has the Department of Fish and Game been asked to study the movement of fish and mammals between the two bays and how a marina jutting out into the channel will affect their movement? Has Fish and Game done any studies regarding those fish which enter the Back Bay for spawning and how will a marina jutting Into their path affect the fish population? Has the issue of nesting by birds which are on the U.S. list of endangered species been addressed? Has the US Army Corps of Engineers addressed the issue of public waterways and navigational rights for the public and the issue of navigational hazards and safety in a narrowed channel? 'Has the US Army Corps of Engineers addressed the problem of water currents and whether they will be altered by the project and if so whether the changed currents will affect siltation, water salinity in the Upper Bay, passage of marine life between the 2 bays? Answers to these environmental questions are needed before an adequate environmental impact report can be written. SPECIFIC COMMENTS: Environmental Information Form: ITEM 24, Should "yes" be marked since eighty -thousand cubic yards is a significant amount of solid waste or litter? ITEM 29. Should "yes" be marked because boat bottom paint is a toxic substance and power boat fuel (gasoline) is flammable and may be explosive. ITEM 31. Should "yes" be marked since 4000 truckloads for approximately 20-mile round -trips and 125 power boats could be considered to represent a substantial increase in fossil fuel consumption (with associated atmospheric pollution)? u I J I J u n 1 Ll Page 3, Castaways Page 4. Floatation: Should CFC-produced foam products be excluded as floating devices in order to promote uses of alternatives which do not destroy the ozone shield? Page 4. Restrooms: What is the greatest distance between the project's slips and on -shore restrooms? Does the City have a stated policy regarding proximity to restroom facilities and slips at piers in order to promote usage of on -shore restroom facilities? If the City does have such a policy, does the project conform with the policy? Having adequate on- shore restroom facilities which are near the boats might help prevent discharge of human wastes into the Bay. ' SPECIFIC COMMENTS: ENVIRONMNETAL CHECKLIST FORM ITEM la: Will the alteration of the floor of the Bay alter water currents? Will dredging and reshaping the contours of the Bay floor affect siltation of the Bay or cause current changes which might affect islands in the near vicinity in the Upper Bay? Will dredging affect the pilings which support ' the Bridge? ' ITEM id. Should "yes" be marked since the temporary road and its dust are likely to destroy unique physical features of the upper Castaways property? Aren't these bluffs unique geologic features which, by law, ' must be protected? How do the City, Coastal Commission and other agencies propose to ensure the protection of these bluffs? The EIR should ' provide specific explanations for how the Bluffs will be protected. ITEM 2a. Should the answer be "yes" since trucks (in the construction phase) and power boats later will cause substantial air emissions and deterioration of ambient air quality? Do power boats have pollution standards and emission controls? ' "yes" ITEM 2b. Should the answer be because the trucks and power boat exhausts stink and other objectionable odors may come from the dredged material. ' AIR, ITEM 2. Should a "d" be added to cover dust which will affect both the children in the pre-school at the Lutheran Church and the neighborhoods downwind of the project? I Page 5, Castaways ITEM 8. Land Use. With this type of project, how much open space must be set aside? Where will the open space issue be dealt with? How will the issue of any open space requirement be addressed? As mitigation for the 4 acres of public water surface lost to the project, should 4 acres of parkland be set aside elsewhere in the City? ITEM 9. Natural Resources. Should "yes" be marked here because the Back Bay is a major natural resource for recreation and the preservation of endangered species. Any alteration in the water quality and access to use bf the water surface represents a diminution of what is now a natural resource freely available to the public. ITEM 10a. Should the answer be "yes" since a conservative estimate of 12,500 gallons of fuel stored on the boats represent a risk of explosion or release of haiardous substances? What if a large diesel boat develops a ruptured tank? Should special clean-up facilities be required for such a possibility since the Back Bay is so very fragile environmentally? ITEM 10b. Should "maybe" or "yes" be marked because in some scenarios, evacuation of Newport Beach residents from the low-lying areas would require using Upper Newport Bay as an escape route (land routes being gridiocked) and boats and docks adrift at the Coast Highway bottleneck would obstruct this marine evacuation route? ITEM 11. Should "yes" be marked unless liveaboards, including weekenders, are strictly prohibited? The Back Bay's eco-system is particularly vulnerable and must not have discharge from boats entering the water. ITEM 13a. Should the answer be "yes" for Dover Drive? ITEM 13b. Shouldn't the answer be "yes" particularly for parking for the church above the project during certain seasons of the year or holidays? ITEM 13d. Should the answer be "yes" particularly if the project will be gated and if traffic backs up on Dover Drive? Will the public have free access to the marina or will the project be gated? 1 F �J I 1 LI ' Page 7, Castaways ATTACHMENT B: ' ITEM 29. Fuel and other chemicals stored on boats will be at the marina and may pose a hazard. tEarth, Item 1(a). Is this statement correct since the epicenter of the most recent earthquake in Newport Beach was in this immediate area? ITEM 1(d). Isn't this statement contradicted by Item I(b) above because if ' a road is built across the bluffs the geological features will be altered. ITEM 1(f) If the flow rates between the upper and lower bays are altered, ' isn't it possible that siltation will increase? Air, Item 2a. If dredging is required for maintaining depth at the slips, ' won't the dredged material increase air pollutant emissions every time dredging occurs? ' Water, Item 3a. Shouldn't the "ongoing engineering studies" regarding currents, siltation, be addressed before the EIR is written and the information used for the preparation of the EIR? An EIR should take into ' account the depth of the bay in the area of the marina and alterations in the depth of the water at the marina and how the changes will affect siltation, currents, etc. of surrounding areas. An EIR should also take into account the long-term need to maintain the depth of the marina by dredging. ' ITEM 3 (h) Water will also be needed for showers, toilets, cooking aboard ' the boats. Will the washdown of boats into the Bay increase the chemical pollution of the Bay? Could facilities be installed now that would help the police to monitor water pollution from boats at the marina? Animal Life, Item 5(a) and 5(d). Won't larger aquatic animals and fish be deterred from going into the Upper Bay because their unimpeded pathway ' between the 2 bodies of water has been reduced? Natural Resources, Item 9(a) The Back Bay, a natural resource for recreation on the part of swimmers and persons using rowing boats and small sailing boats, is both fragile and limited in size; therefore, when the surface of the water is used for private purposes, the public's use of and access to the water (the public's usable environment) is diminished. 1 Page 9, Castaways 1 Item 21(b). What evidence supports these statements? The volume of water will be increased but the volume of water accessible to the general public will decrease. The decrease in the size of the passage between the 1 2 bays may decrease the usefulness of the habitat to larger marine creatures which move from salt water to fresh water habitats and vice 1 versa. The decrease in the width of the navigational channel may pose navigational hazards. J 11 1 i i 1 i i 1 1 1 i 1 Appendix C.

The site encompasses approximately 16 acres, including approximately 4 and 12 acres onshore and offshore, respectively. The site is bounded on the north by an ascending bluff, the east by Newport Back Bay water, south by Pacific Coast Highway, and west by Dover Road. Site access is provided from Dover Road. The land portion of the site is relatively flat lying with a slight gradient toward the east (Plate 1) The eastern land limits are marked by a sea wall. A 36-inch diameter storm drain and buried telephone cables exist near the toe of the bluff. No man-made structures other than a sea wall and storm drain outlet were noted during the field investigation. The proposed development is a 125-slip marina which incorporates the land area and the western portion of Newport Back Bay between the bluffs and the channel centerline. Proposed construction includes excavation of 56,000 cubic yards of existing hydraulic fill and underlying native soils and approximately 20,000 cubic yards of dredge material from Newport Back Bay. Scope of Service L&A's scope of service included a literature review of documents made available pertinent to the site, and a subsurface field investigation consisting of soil sampling of seven onshore and seven offshore borings. Chemical analysis was by a California OHS -certified laboratory. The data obtained were performed reviewed and analyzed by L&A. Specifically, L&A performed the following: Reviewed reports and data pertinent to the site made available to L&A. • Prepared a Site Safety Plan prior to commencement of the field work. Performed a field investigation consisting of seven onshore and seven t offshore borings. All borings were logged and sampled by an L&A geologist. • Chemical analyses were made by a California OHS -certified laboratory for pesticides, herbicides, heavy metals, and Total Recoverable Petroleum Hydrocarbons (TRPH) using Environmental Protection Agency (EPA) and California Administrative Code (CAC) methods. 3 1790649-03 • Reviewed and analyzed the data with respect to contaminant levels and suitability of soils for use as hydraulic fill. • Prepared this report summarizing our findings and conclusions regarding chemical screening results. Background San Diego Creek drains into Newport Back Bay. The area around San Diego Creek has been and currently is agricultural, commercial, and residential. The Tustin Marine Corps Helicopter Air Station is located at the north end of the creek. In the past, Newport Back Bay has been closed to water body contact activities due to pesticides. Based on the past history of Newport Back Bay area and potential for contaminants in onshore and offshore sediments, the soils were sampled and tested to detect the presence of petroleum hydrocarbons, pesticides, herbicides, heavy metals and toxicity levels. Previous studies of the subject site were geotechnical (References 1 through 4 and 6 through 9) that addressed the site's geotechnical conditions and the use of onsite materials as fill soils. Converse Consultants evaluated the engineering properties of the soils with respect to their intended .use. In addition, the data of an initial assessment for potential offshore soil contamination in the proposed dredge area (Reference 5) was reviewed. These data include soil. identification and screening for priority metals, pesticides and PCBs at five locations. Samples consisted of offshore surface sediments within the Newport Back Bay channel area. i Regional and Local Geology The Castaways site is situated in the coastal portion of the Peninsular Range Province. This geomorphic region has a long and active geologic history that includes deep marine sedimentation in Tertiary times with subsequent cycles of folding, uplift, coastal erosion and deposition. Bedrock exposed in the bluff adjacent to the site consists of Tertiary Capistrano Formation which underlies the surficial deposits of hydraulic fill, beach deposits, and alluvium. Based on previous data (Reference 5), offshore marine sediments vary in thickness from about 3 to 52 feet. Bedrock beneath these deposits is Capistrano Formation claystone and sandstone. The marine sediments typically consist of inter -layered silts and clays within the upper 1 to 3 feet. These are typically underlain by coarse to fine-grained sands and silty sands. Shell fragments vary from trace to abundant amounts intermixed and in layers within these sandy deposits. - 3 - O � UIGNTGN AND AS 010ATA WC 1790649-03 Hydraulic fill caps the onshore portion of the site to an average depth of about 8 feet based on the subsurface data (Appendix C and Reference 1). The hydraulic fill consists of sandy silts to silty sands with scattered gravel pockets or lenses. Beach sands, alluvium and clayey siItstone underlay the hydraulic f111. Descriptions of these deposits are provided on the borings logs (Appendix C) and in References 1, 2, and S. Ground water was encountered in all land -based borings at a depth of about 7 to 8 feet below the existing grade. Field Investigation L&A performed a field investigation that consisted of land and offshore -based borings. The land -based borings were advanced using a hollow -stem auger drill rig. A vibracore drill rig advanced the offshore borings. A total of 14 borings was advanced, seven onshore (Borings B-1 through 8-6), and seven offshore (Borings B-7 through B-118). Boring locations are shown on Plate 1 (In Pocket) All borings were logged and sampled by an L&A geologist. Field procedures and boring logs are provided in Appendices B and C, respectively. Samples were collected to evaluate chemical constituents using EPA and California Department of Health Services (OHS) test methods performed by a California Certified Laboratory. Samples collected were analyzed to evaluate toxicity potential and the presence of heavy metals, pesticides, PCBs, and petroleum hydrocarbons in soil. The chemical analytical reports are provided in Appendix 0 and summarized in Tables 1 and 2. EPA and CAC test methods used in the chemical analyses are provided below.

Onshore boring locations are based on field measurements from existing man-made features at the time of this investigation. Summary of Findings Based on the field investigations and laboratory data, L&A presents the following findings: • The sediments underlying the onshore portion of the site consist of unconsolidated gravel underlain by light to dark brown fine to medium grained loose, silty sands with local zones of coarse sand and sandy silt/clay. A color change to dark gray was observed in borings B1-86 at depths ranging from 7 to 10 feet below grade, and a layer of siltstone clasts was encountered at depths from 13-17 feet below grade. These clasts 1 are underlain by a slightly stiff, dense clayey sand unit. Shell fragments are abundant in the upper 2-3 feet of borings B4 and B6, and were scattered from 9-11 feet below grade in boring B5. Ground water was encountered in each boring at depths of about 6 to 8 feet below grade with local exceptions of up to 10 feet below grade. 1 Thickness of onshore hydraulic fill averaged about 8 feet. • Soils encountered offshore included dark gray -green micaceous fine sand, silt and clayey silt with gravel and abundant shell fragments. Total depths of borings varied from 1 to about 7 feet below the bay floor. • A review of the chemical analytical data (see Tables 1 and 2) showed that Organochlorine and Organophosphate Pesticides and PCBs were below detection limits in both onshore and offshore samples. Very low concentrations of DDT and its derivatives 000 and DOE were detected in samples collected from the harbor floor surface sediments (Reference 5). No pesticides were detected in samples collected during this investigation. Priority metals, including Hexavalent Chromium, were detected at concentrations well below the California Hazardous Waste Total Threshold Limit Concentration (TTLC) standards as defined under CAC Title 22. • Fish bioassays for toxicity evaluation of selected samples according to CAC Title 22 showed 100% survival in all of the samples. • Total Recoverable Petroleum Hydrocarbons (TRPH) were detected at concentrations ranging between 7 and 200 ppm, except for 1,400 ppm in sample B-1 at 3.5 feet below grade. Summary of Conclusions Total Recoverable Petroleum Hydrocarbons (TRPH) were detected in all samples 1790649-03 If you have any questions, please do not hesitate to contact the undersigned at (714) 752-8088.

The development is presently planned to consist of a new, marina approximately 1400 feet in length. Associated construction is expected to include demolition of the existing concrete bulkhead, removal of the existing spit of land to the north of the existing bulkhead, and construction of: a replacement bulkhead; a new underwater steel sheet pile bulkhead; a floating boat dock; and a fixed pile -sup- ported boardwalk over the water near the shoreline. The project site location is shown on the following Vicinity Map, Figure 1. Converse Consultants, Inc. performed a preliminary geotechnical investigation for ' the Castaways Commercial site landward of the existing bulkhead, and the results were presented in a report dated 16 August'1982 (CCI Project No. 82-02161-01). Purposes of Study The purposes of this preliminary investigation were to explore and evaluate the subsurface conditions at the site and to provide tentative geotechnical recommendations for design and construction of the proposed ' marina and bulkhead walls. ' This study was intended to provide sufficient geotechnical data and recommendations for preliminary planning and design, and to ascertain if any subsurface conditions existed that could significantly impact the development of the proposed facilities. Because construction details are in their preliminary stages, recommendations presented in this r] L� report are tentative at this time. It is intended that they be used in preparation of your feasibility report to The Irvine Company.

' PROPOSED DEVELOPMENT Based on discussions with you, we understand that the new construction , tentatively will include the following: 1. Demolition of the existing concrete bulkhead and replacement with a new bulkhead. , Z Possible removal of the existing spit of land at the northern ' end of the existing bulkhead. 3. Installation of new marina facilities along the 1400t lineal feet of shoreline adjacent to the main access channel. The , new floating docks will be anchored by guide piles. 4. Installation of a submerged sheet pile bulkhead offshore to , enable an increase in the water depth in the marina area without affecting the natural bay bottom within the tidally - affected zone. The bulkhead would retain the natural bay bottom at elevation - 3 (MSL) landward and would allow dredging to -8 (MSL) and deeper seaward. I 5 ' 5. Dredging of the marina area to provide for greater water depth ' seaward of the submerged bulkhead. 1 6. Construction of a fixed, pile -supported boardwalk in the bay between the floating docks and the shoreline. SITE CONDITIONS Surficial Conditions ' The site is located adjacent to the west bank of the Newport Bay harbor channel, east of Dover Drive, and' north of the Pacific Coast Highway bridge across the harbor channel. Most of the site's 1400-foot site is underwater at mean tide. The exceptions are the existing bulkhead to the south and the projection of land located to the north of the bulk- head. Some of the bay bottom sediments are exposed at law tide in the vicinity of the existing concrete bulkhead. ' Subsurface Conditions ' Based on our test borings, the site is generally underlain by marine sediment deposits overlying bedrock. Borings B-2 through B-7 were drilled using a 5-inch rotary auger rig mounted on a barge. Borings B-1 and B-8 were drilled using a truck -mounted hollow -stem auger 5 inches in diameter. Boring B-1 was drilled east of the existing bulkhead. Boring ' B-8 was drilled at the projection of land to the north. Subsurface soils encountered, in general, consisted of marine sediments varying in thickness from 3 feet to at least 51.5 feet, underlain by ' hard Capistrano claystone and sandstone bedrock. An old buried channel Converse Consultants Orange County i 6 , cut into the bedrock runs east to west along the southwest side of the site. Bedrock was encountered at elevations ranging from -8 feet MSL , (B-5) and -35 feet MSL (B-1). Bedrock was not encountered at elevations ranging from -30.5 feet MSL (B-3) to -53.0 feet MSL (B-7). Marine Sediments , Marine sedimentary deposits varied considerably both vertically and horizontally in soil type and consistency. Sands and silty sands encountered in Borings B-3 and B-7 were fine grained, wet, loose to very dense, with traces of shells and shell fragments. Sands and silty sands , between 25 feet and 48 feet in B-7 were loose, while a very stiff moist clay layer was encountered below a depth of 48 feet. Borings B-1 and B-4 encountered fine sands underlain by sandy clay and clay layers. Borings B-2, B-5, and B-6 encountered clay and silty clay , soils from 3 feet to 9 feet in thickness. The clay layers were moist to wet, soft to hard in consistency, varying from intensely laminated to , nonlaminated and sometimes contained thin sand layers. Capistrano Formation (Tc) r The Capistrano bedrock encountered consisted primarily of claystones and sandstones that were moist to very moist and very stiff to hard in consistency. Microfossils (Forams) were frequently present. ' A 3-foot layer of hard, massive dolostone was encountered at the top of , the Capistrano Formation in B-1. 1 Convuse Consultants Orange County ' Fill (Ad) ' Fill was encountered above mean sea level in Boring B-8. The fill ' consisted of silty sands and silty clays that were slightly moist to moist, loose and firm in consistency, with shells and shale fragments. A detailed description of the subsurface site conditions can be obtained from the logs of the test borings presented in Appendix A. EVALUATION AND PRELIMINARY RECOMMENDATIONS General Design Considerations Based on the results of our field and laboratory investigations, com- bined with our engineering analyses ,"experience, and judgment, we are of the opinion that the development of the site, from a geotechnical engi- neering standpoint, will be significantly influenced by the variable nature of the soils underlying the entire site, and by the fact that ' virtually the entire site is under water. In addition, the marine sediments are susceptible to liquefaction during strong earthquakes, in which the soils could temporarily be transformed into a liquid -like mass having virtually no shear strength to sustain loads. Proposed bulkheads supported on or over these loose saturated soils in their present state could be subjected to moderate to heavy damage due to ground subsidence and/or lateral movements in the event of soil liquefaction during strong ' earthquakes. Appropriate consideration should be given, therefore, to provide adequate lateral retention of the new bulkheads. u I ' Converse Consultants Orange County 8 Vertical Pile Capacity The fixed boardwalk will be reportedly supported by 12-inch-diameter pipe piles driven into the marine sediments and/or bedrock. Depending on the boardwalk location relative to the shoreline, the depth to bed- rock could vary considerably. If the boardwalk is relatively close to the shoreline, vertical support will be derived exclusively in the bedrock materials. Piles should penetrate at least 10 feet into undis- turbed bedrock or at least 20 feet into competent marine sediments. For budget estimating purposes, an average of about 15 feet of pile pene- tration below the mudline should be anticipated. Vertical allowable downward pile design capacities for piles founded in bedrock can be assumed to be 50 to 100 kips, depending on materials penetrated and driving resistance. Predrilling may be required in shallow bedrock areas to facilitate pile installation. The predrilled auger hole should not exceed 60% of the pile diameter. Floating Docks - Anchor Piles The proposed floating dock anchor piles are intended to provide lateral support for the floating marina structure due to wave, current, vessel impact, and seismic forces. As requested by you, we have considered only 12-inch-diameter pipe piles for lateral support. Pipe piles will not be interconnected, but will be individually free standing. A laterally -loaded pile analysis was conducted using pile properties supplied by Cash & Associates along with soil properties determined by our laboratory test program. The piles were assumed to have free heads with a maximum horizontal deflection at the mudline of 0.5 inch. Three cases were considered: (1) pile in bedrock; (2) pile in sand (sedi- ments); and (3) pile in clay (sediments). Comhrss Consultants orange County 1.1 Ij E Resulting lateral capacities, depths to maximum and zero moments, and minimum pile embedments are presented in Table I. The design values for sand and clay soils given in Table I generally are conditional on the assumption that the soils penetrated by the driven piles will be at least firm and/or medium dense in consistency. Some of the sediments may, in fact, be loose or soft, and therefore, piles could be dislocated or knocked out of plumb by lateral loads caused by a seismic event or other forces. We understand that piles so affected will be reset and redriven.

Converse Consultants Orange County 10 Due to the hardness of the Capistrano claystone materials, it is ex- pected that piles driven into bedrock will encounter a substantial resistance to driving. For comparison purposes, observe the drive energies recorded in the boring logs during driving of our cylindrical sampler. The resistance to driving, as measured by drive energy, into the bedrock was generally much greater than into the sediments. Driving the 12-inch diameter pipe .piles into bedrock will generally require a much greater drive energy than driving into marine sediments. Predrill- ing into bedrock may be necessary to achieve the desired embedment for both the boardwalk and the floating dock piles. Steel Sheet Pile Bulkhead It is proposed to provide a greater water depth at the marina by driving a sheet pile bulkhead wall at approximately the -3 foot MSL bay bottom elevation. The bay bottom east of the sheetpiling will then be dredged/ excavated to -8 feet MSL. Shallow Capistrano bedrock can be expected within about 100 feet of the shoreline, and as a result, may be encoun- tered in this area when dredging to elevation - 8 MSL or below. Por- tions of this deposit will be difficult to excavate and may require more heavy-duty equipment. The steel sheet pile bulkhead may be designed based on the soil/bedrock parameters presented in Table II. TABLE II SOIL/BEDROCK PARAMETERS FOR BULKHEAD DESIGN Sand Clay Bedrock Angle of Interal Friction, degrees 32 Total Unit Weight, ppcf 125 Submerged Unit We�ight,pcf 61 28 36 125 105 61 41 Converse Consultants orange County L III ' Sheet pile driving resistance can be expected when attempting to pene- trate portions of the Capistrano bedrock formation. The use of vibra- tory hammers may facilitate bedrock penetration when compared to conven- tional impact hammers. If surcharge loads are anticipated above the bulkhead, an additional uniform lateral surcharge equal to one-third of the vertical surcharge pressure for unrestrained conditions or one-half the vertical surcharge pressure for restrained conditions should be included in the design. In the event that deadman or soil anchors are required for bulkhead stability, deadman or soil anchors should extend beyond a 35 degree line extending upward from the point of zero moment in the bulkhead. The deadman anchor resistance would be provided by passive earth pressure against the face of the block, while soil anchors ' would obtain frictional resistance along the anchor length. If deadman anchors are to be located below the water table, the excavations should be dewatered prior to preparation for pouring of concrete. Excavations for deadman anchors should be observed by the Soils Engineer prior to ' approval. Additional soil/bedrock parameters for design can be pre- sented on request. ' Concrete Sheet Pile Bulkhead ' It is tentatively proposed to remove the existing concrete bulkhead and spit of land to the north and install a concrete bulkhead with a deadman ' type anchorage. Due to the potential for some liquefaction of the marine sediments during a significant seismic event, it.is recommended ' that consideration be given in design to providing additional embedment in the liquefaction resistant clays, sandy clays, and bedrock, as necessary, to offset the additional active pressures caused by liquefac- tion of the saturated upper sands on the landward side of the ' bulkhead, ' Convene Consultants Cnnge County 12 and the loss of passive resistance of the bay sands on the seaward side. The concrete bulkhead may be designed based on the values presented in , the Steel Sheet Pile Bulkhead section of this report. Removal of the spit of land north of the existing concrete bulkhead can be accomplished by normal earthmoving equipment, e.g., a backhoe. Our recent Boring B-8 shows bedrock is 15 feet beneath the present surface. , Effect of Main Channel Dredging M The access channel located to the east of the proposed Castaways marina , is currently being dredged, by others, to a depth of -11.3 feet MLLW (-14 feet MSQ . The bottom of the dredged channel will be lowered , approximately 0 to 3 feet below existing channel bottom elevation. The effect on the proposed marina construction is, therefore, expected to be ' minimal. However, bay 'bottom elevations should be verified prior to final design and construction to determine potential adverse impacts on the proposed construction. ' Corrosion Protection ' Laboratory chemical tests performed on soil samples from the site indicated sulfate concentrations between 385 and 398 ppm, chloride , concentrations generally between 408 and 1215 ppm, and pH between 7.65 and 7.8. Laboratory resistivity tests indicated values between 600 and ' 850 ohm -cm for the on -site soils. ' Soils with sulfate concentrations less than 1000 ppm generally are con- sidered to have a low corrosive effect on ordinary concrete, and, there- ' fore, a Type I Portland cement may be considered for concrete that will ICI u Converse COMIhInts OnngG County 13 be exposed to the on -site soils. Soils with a chloride concentration ' more than 700 ppm and less than 1500 ppm generally are considered to have a severe corrosive effect on mild grade steel. The resistivity tests indicate that the on -site soils generally are conducive to severe electroytic-type corrosion. A corrosion consultant familiar with the marine environment should be retained for appropriate recommendations regarding corrosion protection measures for the development in light of the use of concrete bulkheads, pipe piles, and steel sheet piles in the bay. Supplemental Evaluation and Review The conclusions and recommendations presented in this report are preli- minary and must be reviewed and re-evaluated when more specific project design details are forthcoming. At the present time, the design is only in the conceptual stage. At an appropriate time after 'preliminary design, it will be necessary to obtain supplemental data in the form of ' bottom and subbottom profiling by the use of seismic methods, standard soil borings, vibracore borings, or a combination of these or other ' methods. Additional laboratory testing and analysis must also be anti- cipated. CLOSURE ' The information contained in this report has been carried out in accor- dance with accepted geotechnical principles common to the local area in ' which we practice. No other warranty is either express or implied. The tentative conclusions and recommendations contained in this report are ' professional opinions, drawn from data obtained from representative Converse Consultants Orange County �r t 14 exploratory excavations and laboratory testing. Results so obtained are assumed to be indicative of the general subgrade characteristics. Variations in subgrade type, color, and physical properties will exist between exploratory excavations.

During the site and geologic reconnais- sance, the surface site conditions were noted, mapped, and the approxi- mate locations of the test borings were determined. ' A total of eight (8) test borings were drilled between May 21 and May 28, 1986, at the locations shown on the enclosed Geologic Map, Drawing ' 1. The borings were advanced using a truck -mounted, rotary -wash auger drill rig, and a barge -mounted rotary-wash/hollow-stem auger rig ' equipped with 4-7/8-inch diameter drill bits. The soils were continu- ously logged by a member of our geology staff, and classified in the field in accordance with the Unified Soil Classification System. 17 I I 1 Standard Penetration Tests (SPT) were conducted at frequent intervals in the test borings conforming to ASTM D1586-67. The resistance to pene- tration in the last 12 inches (SPT) of the total 18 inches of penetra- tion for each test is given in the Boring Summary sheets in this Appendix. Relatively undisturbed samples of the subsurface soils were also ob- tained at frequent intervals in the borings using a drive sampler (2-1/2 inch inside diameter, 3 inch outside diameter) lined with sample rings. The thin -walled steel sampler was driven into the bottom of the borehole with successive drops of a 140-lb driving weight falling 30 inches. The drive energy required for one foot of sampler penetration for each sample is shown in the Boring Summary sheets. Bay borings were located by a conventional survey transit and triangulation methods. Formalized logs of the test borings are presented in the following pages of this Appendix.

'representative undisturbed soil and bedrock samples for the purposes of classification and to aid in assess- ing physical properties and engineering characteristics. A brief 1 description of the various laboratory tests conducted for engineering in following The purposes by our office is presented the paragraphs. amount and selection of the types of testing for a given study are based on a geotechnical conditions of the project. Results of the laboratory tests performed for this study are summarized on the boring logs (Appen- dix A) and in this Appendix. Moisture Content and Dry Density Moisture content and dry density tests were performed on relatively ' undisturbed samples obtained from the field in accordance with ASTM Test Method D2215-80. These data are used to aid in the classification and correlation of the subsurface materials, and to provide qualitative information regarding soil strength and compressibility. The results of the moisture and density tests are presented on the boring logs (Appen- ' dix A). ' Direct Shear Tests Direct shear tests were performed on relatively undisturbed samples to evaluate shear strength. The tests were performed on samples under increased moisture conditions. The samples to be tested are contained in brass -lined rings placed ' directly in the shear apparatus and sheared under constant strain control. Strain rates can be varied for the type of test. The samples are subjected to a normal load appropriate to the anticipated condi- tions. The shearing strength of the material is obtained from the measured shearing load versus deflection. The results of the tests are summarized below: I Converse Consultants Orange County [F e Boring Material Peak umb Friction sion Angle 1 14.5 Silty Clay 740 28 1 24 Clayey Sand 1330 32 2 11 Olive Gray Claystone 820 26 4 16 Olive Gray Claystone 2220 30 6 5 Olive Gray Clay 660 22 8 25 Olive Gray Claystone 1410 33 Atterberg Limits Atterberg limits of representative soil samples were determined in accordance with ASTM Test Method 04318-84. The results of the tests are presented below: Boring Depth, Liquid Plastic Plasticity 2 6 Very Dark Gray 88 48 40 SILTY CLAY 4 10 Dark Olive Brown 80 37 43 SILTY CLAY Test results indicate that the above sediments are highly plastic clays. Sieve Analysis The grain -size distribution characteristics of selected soil samples were determined in accordance with ASTM Test Method 0422-63 without hydrometer testing. The results of the tests are presented at the end of this Appendix. LE Corrosivity Tests Laboratory tests for the determination of the pH, resistivity, soluble sulfate, and chlorides concentrations were performed to evaluate the corrosivity of the soils on common engineering materials that may be in contact with the subgrade soils. Results of the tests performed for this study on representative soil samples are summarized below. The tests were performed by Anaheim Test Laboratory of Santa Ana, California.

The channel is bounded by high bluff on the north bank and low land on the south side. Survey data measured in 1988 and summarized in Figure 2 indicates that the bathymetry over this reach generally conforms to the channel alignment as isobaths are parallel to shore (Noble Consultants, 1989a). The irregular shape of the individual depth contours and an anomalous depression near the site at mid -channel are believed to be the remnants of recent dredging operations (County of Orange, 1988). The bathymetry was most recently surveyed in September, 1989 for design purposes (S.E.A. Contractors, 1989). (See Figure 3.) Comparison of this data, shown in Figure 3, with the earlier measurements indicates that no significant depth changes occurred over the short time between the two surveys. Localized depth changes near the Pacific Coast Highway bridge were also reviewed for depth variation over time. A review of data recorded near the bridge, between 1986 and 1988, shows that depth changes of two to three feet have occurred. This fluctuation is also estimated to be man-made as a result of the recent channel dredging activity. 1.2 Tides: Tides along the California coast are characterized as mixed semi - diurnal, and consist of two unequal high tides and low tides each day. Tides at the Newport Harbor entrance are referenced to the Los Angeles Harbor gauge station. Benchmark elevations for this primary station summarizing the tidal characteristics, and the corrections to Newport Harbor, are presented in Table 1 (NOAA, ' 1987). The table also includes high water elevations of record that were measured on January 27, 1983 and January 17, 1988 and represent the most extreme conditions to date. 1.3 Winds: An annual distribution of wind speeds by direction in the coastal ' Orange County area is listed in Table 2. The prevailing directions are from the west and northwest with wind speeds generally four to ten knots. In general, wind speeds are 20 knots (23 mph) or less about 90 percent of the time. Wind velocities in excess of 20 Iknots occur only about four percent of the time. Castaways Marina EIR April 30, 1990 , Page 2 1.4 waves: , No measured wave data have been recorded near the project site. However, since the wind fetch within the channel is limited, wind , generated wave heights are expected to be small. It is estimated that wave heights no larger than 0.5 to 1.0 feet would be generated during more severe storm wind conditions. 1.5 Currents: , T}ia magnitude of tidal currents that flow past the site corresponds ' to the amount of rise or fall in tide. For large tide fluctuations, particularly during ebb tide, currents at the site can be swift as a result of the tidal prism drainage from the upper Newport Bay. Ebb currents will also increase in response to the , volume of fresh water runoff delivered by the tributaries during storms. Recorded data of current velocity and pattern at or near the site , is limited. Occasional measurements by the County of Orange (1987) at the Pacific Coast Highway bridge indicate that the average velocity ranges at mid -channel from 2.0 to 3.4 feet per second (1.2 ' to 2.0 knots) during peak velocity conditions. Measurements have also been made to determine velocities associated with extreme tidal fluctuations. bats. was obtained in 1988 during an ebb tide fall of 8.0 feet and a subsequent flood tide rise of 5.1 feet. , Temporal velocity variation near the site was recorded at mid - channel at four depth intervals (Noble Consultants, 1989a). ' Results of these measurements are shown in Figure 4. Maximum ebb and flood tide velocities were approximately 3.2 and 1.5 feet per second, respectively (1.9 and 0.9 knots). Evidence of flow stratification was also observed during the onset of flood tide as ' faster flood currents were observed at deeper depths. It is believed that this result reflects a short-lived condition of denser sea water moving upstream beneath a residual ebb discharge ' of less saline upstream water. This stratification was observed only during the initial stages of flood tide, and after the water became well -mixed, this phenomenon disappeared. ' 1.6 Water Circulations: Water circulation patterns were observed in the laboratory using ' a physical hydraulic model especially built to investigate the project site area (Noble Consultants, 1989a). Simulations were conducted under the existing and the proposed project conditions. , 0 ' Castaways Marina EIR April 30, 1990 Page 3 ' The results of the without project tests formed the basis of assessing the hydraulic baseline condition of water circulation. Figures 5 and 6 show the flow patterns for ebb and flood peak velocity conditions that were observed in the physical model. In ' general, tidal currents flow past the site in conformance with the main channel alignment with the exception of two counter -currents. During ebb flow a small reverse circulation forms near the existing ' bulkhead at the project site. The observed gyre is believed to be caused by the upstream shoreline bluff projection which disrupts an otherwise smooth hydraulic streamline. During the flood tide ' condition, a larger circulated water pattern was observed immediately upstream of the project site, just beyond the same shoreline bluff projection feature. ' 1.7 Precipitation: Measurements recorded at the Newport Harbor gage indicate that the ' average precipitation for the area is about 11 inches (NOAA, 1988). Table 3 presents an average monthly precipitation occurrence compiled from the past 60 years of data. As can be seen from the table, rainfall predominates mostly in the winter between the ' months of November and April. ' 1.8 Sedimentation: Rainfall and storm water runoff are the primary cause of sediment delivered to the upper Newport Bay and downstream areas. Sediment ' yields from San Diego Creek watershed and its San Diego Creek and Peters Canyon Wash tributaries (See Figure 1) contribute the majority of sediment that ultimately deposits within the estuary. ' The volume of sediment delivery depends in large measure on the extent of the land use within the watershed area and the amount of precipitation and subsequent runoff. ' 1.8.1 Annual Delivery Estimates of average annual sediment yields may be inferred from the findings of the sediment monitoring program that has been undertaken by the County of Orange in San Diego Creek since 1985 (County of Orange, 1987, 1988). Table 4 summarizes their recorded water discharge and rainfall data as well as calculated sediment ' transport volumes. It is noted that a continuing reduction of sediment delivery has been estimated since 1982. Urbanized development and lower amounts of rainfall are believed to be the ' primary reasons for this trend. Castaways Marina EIR April 30, 1990 Page 4 1.8.2 Storm Delivery Greater volumes of sediment can be delivered during individual and more intense storm events when runoffs are highest. A study by Boyle Engineering Corporation (1982) summarized runoff hydrography for 24-hour duration storms using parameters outlined in the Orange County Flood Control District Hydrology Manual. This data is shown in Table 5 for storms having 2, 5, 10, 25, 50, and 100 year return periods. Based upon the described storm runoff in the above section, Table 6 presents the estimated resultant sediment supply to Upper Newport Bay for various return storm events under the existing and ultimate watershed condition. The later criteria was selected as the most representative of a future condition within the San Diego Creek (i.e., fully developed) watershed due to the trend in urbanized development. The numbers represent a combined bed load (sediment particles that move along the bottom) and suspended load (sediment that moves through the water column in suspension) volume total. The contribution due to bed load was estimated based upon sediment transport capacity associated with each size of sediment particles which characterize the source material. The suspended load passing a given channel section was assumed to be approximately equal to the quantity of fine sediment (clay and silt) generated from the upstream watershed area. 1.9 Debris: Floating debris and trash is injected into the waters of Newport Bay from a variety of non -point sources upstream and downstream of the .project site. No quantitative data exists that documents the volume of material that is transported by runoff into the tidal stream, but it is believed that the majority of debris is delivered via the upstream tributaries. and storm drains that empty into upper Newport Bay during the initial storm discharges of each years' rainy season. Brief field observations made near the site indicate that minor amounts of trash and debris accumulate along the bank of the west channel immediately north of the project site (Noble Consultants, 1989a). It is believed that this preference may be attributed to the secondary circulation effects of transverse currents caused by ebb flow turning the channel bend. This tends to carry floating debris in a direction normal to the channel and towards the west bank. Furthermore, the circulation pattern that sets up during flood flow (see Figure 6) also tends to encourage collection of I t ' Castaways Marina EIR ' April 30, 1990 Page 5 floating debris and trash. However, this material appears to be ' gradually removed by subsequent high tide and ebb current action. ' 2.0 PROJECT IMPACTS The proposed marina development includes excavation of about 56,000 ' cubic yards of existing upland hydraulic mooring basinand afill to create a new from the adjac, pproximately 24,000 cubi ent channel to accommoc yards of material date new small craft berthing. ' The proposed improvements were assessed for potential short-term and long-term impacts on the hydraulic regime. 2.1 Short -Term Impacts: ' Dredging and excavation activities will temporarily siteidity or Xo t ofs the a mooring sediment basinn excavation is within expected to be increase ' performed using land -based aProject to adjacent waters, 4uipment and therefore be non -impacting It is anticipated that dredging in the channel itself will be performed by clam shell equipment. Disturbance to ' the bottom by removal of material will result in the resuspension Of 'fine sediment that will render the adjacent water muddy or cloudy. Since a large portion of sediment to be dredged is fine sand, the .disturbed suspended solids are expected redeposit locally. Therefore, this imto rapidly pact is considered to be short-term and insignificant construction impact. a 2.2 Long -Term Impacts: The results of the physical hydraulic Consultants, 1989model study (Noble impacts. a) were used as the basis for assessing long-term ' 2.2.1 Flow Pattern In the st ' ar. marina basin co tluff controls and lnw circulaoreline ction lwi marina basin. githin n upstream of Figures 7 and 8 illustrate the flowpattern during n the proposed the ebb and flood tide condition observed in the hydraulic model study. Flow separation occurs along the mooring basin entrance resulting -from the strong velocity gradi oent which occurs from the ' high velocity main channel to the quiescent mooring area. Castaways Marina EIR April 30, 1990 Page 6 Flow pattern during flood flow is independent of structural details located downstream from marina entrance; again the upstream Projection of the west bluff dominates flow definition and is responsible for creation of a large gyre upstream of the marina basin within the area of the proposed channel dock. Circulation within the proposed mooring basin is different for flood and ebb conditions. Two counter -rotational gyres are set in motion by ebb flow; one large gyre sets up during flood flow. The size of the ebb flow gyres depends somewhat on the length and configuration of slope protection and fill along the west bank near the northern entrance to the marina basin. 2.2.2 Debris Accumulation: Floatable tracer material injected in the model to stimulate the "with project condition" indicated that about 90 percent of the floating debris would bypass the marina as illustrated in Figure 9. An estimated ten percent of the floating material was observed to be entrained within the mooring basin. It is therefore surfaceconcluds area at a dock ontoon will not sseverelyystem t restrict minim he normal um of idownstream Passage of debris past the project site. Returning flood flow waters would tend to deliver the marina basin than ebb circulation. However, that most debris originates from upstream sources. 2.2.3 Erosion Effects: I� I I more debris to ' it is estimated The hydraulic model results did not indicate that current velocities will increase within the project limits and immediate channel areas. Therefore, it is concluded that no adverse scour or erosion effects will result from the project im ro p vements. 2.2.4 Sedimentation: Annual Delivery A statistical analysis by Boyle Engineering Corporation (1982) estimated an average annual sediment delivery of 50,000 cubic yards to the upper Newport Bay. Review of the estimated data for two tributaries (San Diego Creek and Peters Canyon Wash) in recent years (County of Orange, 1988) suggests that the fluvial delivery presented by Boyle Engineering Corporation may be overestimated. P I 17 I 1 1 1 D t Castaways Marina EIR April 30, 1990 Page 7 Based upon an annual average precipitation of approximately 11 inches, it is assumed that about 25,000 cubic yards is the representative annual sediment delivery rate exclusive of severe storm events. Of this volume, more than 80 percent of the suspended load is believed to be retained in the upper bay basin. The hydraulic model tests indicated that about ten percent of the remaining suspend material that is transported past the site would be delivered to the marina basin. Therefore, it is estimated that approximately 500 cubic yards per year (25,000 x 0.2 x 0.1) may be transported into the marina basin. Assuming a suspended sediment concentration of 150 mg/l and assuming that deposition occurs only within the inner two-thirds of the mooring basin, this rate of delivery translates to an average annual depth decrease of approximately 0.2 feet per year (Noble Consultants, 1989a). Bed load transport was estimated using a simplified method applicable to estuarine environments (Sternberg, 1972). Based upon an assumed average flow rate of two feet per second past the project site (1.2 knots), and bed material consisting of find sands to silts, an annual transport rate of 0.9 cubic yards per foot of bottom width is estimated. From observations conducted in the hydraulic model, it is assumed that ten percent of this amount is delivered to the mooring basin entrance. This implies a shoaling rate of approximately 55 cubic yards per year. Assuming further that this shoaling is concentrated uniformly in a bar formation over an area of about 9,600 square feet, as shown in Figure 9, an annual rise in channel bottom across the mooring basin entrance of approximately 0.1 feet per year is estimated (Noble Consultants, 1989a). Storm Delivery The estimated sediment supply into the upper bay for the 25, 50, and 100 year return storms are 100,006, 165,000 and 220,000 cubic yards, respectively. As previously discussed, more than 80 percent of this fluvial suspended load and the entire bed load resulting from a return storm event are retained in the upper bay basin. The remaining fraction of suspended load which could be delivered to the Castaways Marina basin was estimated from the previously mentioned hydraulic model observations. Table 7 tabulates the calculated results. Castaways Marina EIR April 30, 1990 Page 8 Based upon the estimated current velocities, bed load deposition during the storm conditions was characterized using the aforementioned Sternberg method. Calculations estimate that the marina is estimated to shoal at a rate of about 0.61 1.0 and 1.3 feet as a result of runoff caused by 25, 50 and 100 year storm conditions, respectively. These numbers are derived from corresponding values of 0.11 0.2 and 0.3 feet due to bed load sources and 0.51 0.8 and 1.0 feet due to suspended load deposition (Noble Consultants, 1989b). 3.0 MITIGATION HEASURES 3.1 Debris Cleanings The project will intercept a portion of floating trash and debris that would otherwise continue downstream to lower Newport Bay. Regular clean up in the marina basin and boat slips would be a practical means to remove the debris from the system. Alternatively, construction of a debris fence or floating boom at the southern edge of the basin entrance would intercept the floating debris returning on flood tide flow which tends to deliver more debris into the marina basin. Regular removal of the floating debris at the fence or boom would improve debris cleaning. 3.2 Boat Slip Designs Hydraulic model studies indicate that a bar may tend to form across the marina basin entrance (see Figure 9). This implies that maintenance dredging may be required more in this zone to maintain project depths. Elimination of boats slips planned near the basin entrance would allow for easier access for dredging equipment. Alternatively, if slips are placed over this section they may be designed to be temporarily removable to allow for periodic maintenance dredging. In order to minimize tidal flow interference, use of adequately spaced plastic pontoons to support the floating docks within the channel is preferable. In doing so, intervention to the ebb flow tide pattern due to the presence of the docks can be minimized. I D I U 1 t I ' Castaways Marina EIR ' April 30, 1990 Page 9 L 4.0 UNAVOIDABLE ADVERSE IMPACTS Sediment accumulation within the project site is an unavoidable adverse impact. It is estimated that maintenance dredging would be required at five year intervals to remove about 6,000 cubic yards of material to maintain project depths within the boat basin. Provisions for removal of the accumulated sediment and its disposal will be required. I 1 I Castaways Marina EIR April 30, 1990 Page 10 5.0 REFERENCES Boyle Engineering Corporation, 1982.

A. de Wit Gentlemen: Subj: Marine Sediment and Seawater Chemistry Investigation Proposed Castaways Marina, Newport Bay, California for the City of Newport Beach, California INTRODUCTION This report describes the collection and laboratory analysis of sediment and'seawater samples, and discusses the resultant data, from -the site of the proposed Castaways Marina in Newport Bay. Marina construction will require that marine sediments be dredged from the floor of the channel between Upper and Lower Newport Bay. ' The site is located along the western side of the navigation channel immediately north of the Pacific Coast Highway bridge Figure 1). The proposed dredge area is aligned roughly north -south, extends about 1200 feet north of the bridge, and varies in width from 60 to 120 feet; it comprises approximately 2.5 acres which will be dredged to a design depth of 10.75 feet ' below Mean Sea Level. The East Newport Heights storm drain discharges into the channel adjacent to southern end of the proposed dredge area. MThe objective of the study was to determine the pollutant chemistry of the sediments that will be dredged during construction of the marina, and to make a preliminary assessment of•the changes in water quality that may occur due to the dredging operation. Marine sediment samples were collected and analyzed for selected trace metals, organochlorine pesticides, and polychlorinated biphenyls (PCBs). Subsamples of sediments were agitated in site seawater (also analyzed for the same set of ' P.O. BOX 2057 SANTA BARBARA. CA 93120 (S05) SBS.SB24 Michael Brandman Associates 1 18 February 1988 Page 2 metals and compounds) to simulate the resuspension that occurs during dredging, and the supernatants were analyzed for the same set of pollutant constituents. Several previous studies of the seawater and sediment chemistry in the vicinity of the proposed Castaways Marina have occurred. The Southern California Coastal Water Research Project (SCCWRP) examined Newport Harbor as one of three possible sources for pollutants entering the coastal waters of California (Young and Heesen, 1974; Young et al., 1975). These studies found elevated levels (relative to open coast values) for trace metals, pesticides, and PCBs in harbor waters, sediments, and tissues of Intertidal mussels, and attributed the greater concentrations to agricultural runoff and use of antifoulant paints. The Environmental Management Agency of Orange County investigated the water quality of Newport Bay (Orange County EMA, 1980). Marine Biological Consultants and SCCWRP collaborated on an extensive investigation of Newport Bay and the surrounding environment (NBC/SCCWRP, 1980), including bioassay studies, trace metal and chlorinated hydrocarbon measurements, and other biological and oceanographic studies. Marine Bioassay Laboratories (1982) evaluated the potential impact of disposal of dredge materials taken from Newport Bay through bioassay studies. Lastly, the Orange County Environmental Management Agency periodically samples and analyzes bay waters and sediments for trace metal, pesticide, and PCB concentrations. SAMPLE COLLECTION The sediment sampling sites were distributed evenly throughout , the proposed dredge area, separated by approximately 230 feet, and were designated CAST-1 through CAST-5 (see Figure 1 and Table 1). The sampling sites were located using trilateration between pairs of horizontal angles measured between onshore structures and features; station accuracy is estimated to be within 10 feet of the location given. , Care was taken to avoid sources of potential contaminants during the sampling and analysis procedures. No sampling devices were used; all samples were collected using the laboratory -cleaned sample containers themselves. All samples were collected at least 8-10 meters away from the boat, and all containers were kept closed through the air -water interface, where contaminants tend to concentrate. ' Five surficial sediment samples were collected by a SCUBA equipped diver from the proposed dredge area using acid -rinsed glass jars with Teflon -lined lids. The diver swam to the bottom with the unopened jars, scooped sediments directly into the jars, and returned through the surface with the jars once again ' capped. Site seawaters to be used in the elutriation process I I 1 I F1 f Michael Brandman Associates 18 February 1988 Page 3 were collected in 5 acid -rinsed one -gallon containers. The closed bottles were lowered through the air -water surface, uncapped and allowed to flood with subsurface water, recapped underwater and brought into the boat. Containers for both sediment and seawater samples were filled completely, with no entrapped air, to minimize sample oxidation prior to analysis. The samples were all collected within a 2-hour time period during the morning of 28 January 1988. The weather was clear and warm, with no winds; the tide was ebbing (flowing seaward) at an estimated speed of about 50 cm/sec (1 knot). The samples were placed on ice immediately after collection and labeling, and delivered to the testing laboratory within 1 hour after completion of the sampling cruise (and within a maximum of 3 hours after collection). LABORATORY TESTING Based on guidance provided by the Santa Ana Regional Water Quality Control Board (Mr. Mikel Adackapara), the following priority pollutant constituents were determined in the testing laboratory: Trace Metals Pesticides/PCBs Antimony Aldrin Arsenic Alpha BHC Beryllium Beta BHC Cadmium Delta BHC Chromium Gamma BHC (Lindane) Copper Chlordane Lead 4,4'-DDD Mercury 4,4'-DDE Nickel 4,4'-DDT M Selenium Silver Dieldrin Alpha Endosulfan Thallium Beta Endosulfan Zinc Endosulfan sulfate Endrin Endrin aldehyde Heptachlor Heptachlor epoxide Toxaphene PCB 1016 PCB 1221 PCB 1232 ' PCB 1242 PCB 1248 PCB 1254 PCB 1260 I I Michael Brandman Associates 18 February 1988 Page 4 These elements and compounds were determined in the five bulk sediment samples, in one sample of seawater taken from the study area, and in the elutriate resulting from agitation of the five , sediments and the site water. Laboratory analyses were conducted by Associated Laboratories (orange, CA) under the direction of Dr. Edward S. Behare. Concentrations of metals were determined using atomic absorption methods, and of organochlorine pesticides and PCBs by gas chromatography (using U.S. EPA Method 8080 for sediments and Method 608 for aqueous samples; U.S. EPA, 1986). The elutriate testing followed methods given by the Environmental Protection Agency/Corps of Engineers 'technical Committee on Criteria for Dredge and Fill Material (Plumb, R. H., Jr., 1981). Sediment particle size distribution was determined using standard dry sieve methods. The grain size and visual characteristics of , the five sediment samples are given in Table 2. , RESULTS AND DISCUSSION The analytical results for sediments are presented in Table 3, and for site seawater and elutriates in Table 4. In addition to values determined during this study, Table 3 also lists reported results from sediments collected at the proposed dredge site in 2986. These comparative results were obtained from the Orange County Environmental Management Agency, and are the most recent data from a set of similar data taken at sampling stations near the Pacific Coast Highway bridge since 1978. With the single exception of mercury, values for all metals in sediment are lowest at station CAST-1, located nearest the Pacific Coast Highway bridge. Mercury concentration is highest at that station. Concentrations of pesticides and PCBs in sediments were all below detection limits except for the compounds DUD, DOE, DDT, and Gamma BHC (Lihdane). Metal concentrations in the site seawater were all below detection limits except for beryllium and mercury; after elutriation, beryllium, mercury, and silver were dete^table. Beryllium and silver were significantly enriched by the elutriation process; mercury concentration remained constant. All pesticide and PCB concentrations were below detection limits In the site seawater and showed no enrichment in the supernatant after agitation of sediments in site seawater. 1 0 0 ' I D] Michael Brandman Associates 18 February 1988 Page 5 following this report: The are attached and complete ' Literature Cited Figure 1.

' The study was carried out by MEC Analytical Systems' Bioassay Laboratory in Tiburon, California according to the scope of work approved by the EPA and Corps of Engineers, LA District and was designed to be conducted under the Ocean Disposal Program that ' would provide results suitable for submittal to the Los Angeles District of the U.S. Army Corps of Engineers and the EPA. It included bulk chemical testing of the test and reference sediments, liquid/suspended phase (L/SP) bioassays, 10-day solid phase toxicity tests, and a 20-day bioaccumulation study. ' The existing depth at the berth ranges from 0' to -15' MLLW. The dredging will provide an average bottom depth of -10' MLLW. The amount of material to be dredged is 25,000 ' cubic yards in a project footprint of approximately two acres. It is proposed that the dredge material will be disposed of at the LA-3 dredge disposal site off Newport Harbor. ' The study was carried out by MEC Analytical Systems' Bioassay Laboratory in Tiburon, California according to the scope of work approved by the EPA and Corps of Engineers, ' LA. r H I 2.0 METHODS ' 2.1 SUMMARY OF TESTING PROGRAM , The testing program described in this report involved several elements. In all, sediment samples from three sites at the proposed marina and the reference site near LA-3 were analyzed for chemical and physical constituents and full bioassay analyses. Chemical ' analyses of sediments, water, and tissues were conducted by Quality Assurance Laboratories of San Diego; all other tests and analyses were conducted by MEC Analytical Systems. Short-term liquid/suspended-particulate phase (20-minute and 96,hour static ' acute) and longer term solid phase (10-day and 20-day flow -through) bioassays were conducted using six species of marine organisms. Bioaccumulation was assessed using ' two of those species from the 20-day flow -through tests. The test species for the liquid/suspended-particulate phase (LISP) tests were Citharichthys ' stigmaeus (sanddab), Hohnesimysis costata (mysid) and. larvae of Strongylocentrotus putpuratus (sea urchin). The ten day solid phase testing was carried out with Nephtys t caecoides (worm), A1acoma nasuta (clam), Holnresitnysis costata (mysid) and Rhepoxynius abronius (amphipod), The 20-day bioaccumulation test used Nephtys , caecoides and Macwna nasuta. Table 2-1 shows how the various species were used in the testing program. Tables 2.2 through 2-7 provide a summary of the test procedures for each ' element of this particular study. The following subsections elaborate on these summaries. All methods and procedures outlined in this section follow specifications in the , Implementation Manual for Section 103 of Public Law 92-532. EPA/Corps of Engineers (1977) (also known as the "Manual') as well as accepted methods of the Los Angeles , District, U.S. Army Corps of Engineers 2.2 TEST ORGANISM PROCUREMENT AND HOLDING Nephtys caecoides, Macoma nasuta, Citharichthys stigtnaeus, Hobnesintysis costata, and ' Rhepoxynius abronius were supplied by Mr. John Brezina (Brezina and Associates, Bioassay Consultants, Dillon Beach, California). Length and weight data for test ' organisms are presented in Table 2-8. N. caecoides, C. stigmaeus, and M. nasuta were collected from Tamales Bay. The H. costata were collected from Monterey Bay, ' California, and theR. abronius were collected in Puget Sound, Washington. All of the test z ' ' species with the exception of the amphipod were shipped in plastic buckets containing ' 10-12 L of water. The amphipods were delivered in Puget Sound sediment by Greyhound Bus. Strongylocentrotuspurpuratus were spawned from stock provided by Pacific ' Biomarine in Venice, CA. ' Test organisms were held and acclimated at the bioassay facility for at least 24 hours (except for the Strongylocentrotuspurpuratus, which were tested immediately upon arrival) prior to placement in test aquaria. All holdinglquarantine areas, as well as the test rooms, ' were environmentally controlled. Following filtration and sterilization, seawater was adjusted to 15°m VC (the temperature required for acclimation). Air temperature of the ' rooms was maintained at 16 m 2°C. ' 2.3 COLLECTION AND PREPARATION OF SEAWATER AND SEDIMENTS All test sediments were collected from the proposed marina site in upper Newport Harbor, ' Newport Beach, California on April 24, 1990 (Figure 2.1). Sediments from the dredge site were collected using an aluminum barrel electric vibracorer with a 10.16 cm diameter. Core samples were taken to a maximum depth of -15.0 feet (MLLW) (Table 2-9). The reference muds were taken on April 23, 1990, from offshore Newport Beach at the location ' shown in Figure 2-2 using a Teflon lined Van Veen grab. The site was divided into three test areas, A, B, and C, which are identified as Test 1, 2, and 3 in the results (Figure 2-1). Five cores were taken from the each test area, except station A-5 where the corer was refused penetration due to rock and shell hash. On board ' the vessel "LoAn", sediments from the test areas were packed in FDA food -grade plastic bags, stored in coolers, covered with ice, and transported to the Bioassay Division of MEC ' Analytical Systems in Tiburon, CA. ' On April 29 30, 1990, the sediments from each site were mixed thoroughly, then screened through 1 mm stainless steel screens. In addition, Puget Sound sediment was screened for use as the control sediment in the R. abronius bioassay, and Tomales Bay sediment was ' screened for use as the control in the solid phase bioassay. After mixing, sediment was placed back into coolers lined with an acid -washed and seawater leached, Food and Drug ' Administration (FDA) food -grade plastic bags, and maintained at 4°C until testing was initiated. The sediments were packed tightly into the bags to ensure that air bubbles were ' not trapped. Reference and dredge site sediments were held for a maximum of 10 days following collection. 3 F Subsamples of sediment for chemical analysis were removed and sent to Quality Assurance Laboratory in San Diego, CA, via Federal Express. Subsamples for grain -size analysis and total organic carbon were shipped to NEC Analytical Systems, Inc. in Carlsbad, CA. San Francisco Bay seawater used in the dredge material bioassays. NEC has a marine seawater intake located at the Romberg Tiburon Center for Environmental Studies in Tiburon„ CA. The seawater salinity was relatively constant at 30 m 2 parts per thousand (PP0. The test solution used in the liquid/suspended-particulate phase bioassays was prepared with seawater and dredge site sediments. Seawater and sediment were mixed to obtain a volumetric sediment to water ratio of 1:4 in a 150-L polyethylene tank at 15°C. Mechanical mixing was supplied to agitate the mixture vigorously for 30 minutes after which the mixture was allowed to settle for one to two hours. The supernatant was used to create 10%, 50%, and 100% test concentrations as appropriate for the biodssays. 2.4 CHEMICAL ANALYSIS OF SEDIMENTS, WATER, AND TISSUE Chemical analyses of bulk sediments, the laboratory seawater, and on test animal tissues were conducted by Quality Assurance Laboratory (Table 3-1). Quality Assurance Laboratory analyzed samples for a suite of heavy metals and organic compounds. MEC monitored water quality parameters in the bioassay tests and determined grain size distributions. Seawater, sediment, and tissue chemical analyses were conducted according to EPA methods, the Manual, the scope of work, and accepted practices of the Army Corps of Engineers. All heavy metal and organic analyses were carried out on the sediment, seawater, and tissue, except for TOC and organotin, which were only measured on sediment. Detection limits were specified for seawater, sediments, and tissue samples in the Scope of Work. All analyses were carried out to those limits within the limitations of the test media and the analytical methods. u I I I H I 1 11 = SAMPLING LOCATIONS • f � 1 • I < !

All other metals were determined by EPA Method 6000 using inductive coupled plasma. 2.4.2 Organics Determinations Water, sediment, and tissue samples were extracted and analyzed for chlorinated pesticides and PCBs following procedures described in EPA Method 8080. Petroleum hydrocarbons and oil and grease were determined by EPA Methods 418.1 and 413.2 respectively. The analysis of polynuclear aromatic hydrocarbons was carried out by EPA Method 8100. 2.4.3 Water Quality Dissolved oxygen was measured using a YSI Model 57 oxygen meter and probe; pH was measured using a Corning 106 digital pH meter. Salinity was measured with a refractometer and temperature with a mercury thermometer. Ammonia was analyzed by Orion 9512 electrode procedures using the Orion 720 digital ion analyzer. 2.4.4 Sediment Grain -Size The sediment samples were analyzed for grain size distribution and total organic carbon by MEC Analytical Systems Laboratory in Carlsbad. The method for grain -size analysis follows Plumb (1981). This method combines the dry sieve and the pipette methods to analyze the smaller particle sizes The analysis of total organic carbon is performed using a persulfate wet oxidation (Menzel and Vaccaro,1964) 2.5 BIOASSAY PROCEDURES The procedures used for all bioassays are detailed in the Manual and summarized- below. The study consisted of bioassays of the combined liquid/suspended-particulate phase and of the solid phase of the dredged material, and bioaccumulation tests on the solid phase. Tables 2-2 through 2-7 summarize the test conditions. 17 i u 2.5.1 Liquid/Suspeaded•Particulate Phase BIoassay ' A summary of the sea urchin sperm toxicity test methods is presented in Table 2.2. The echinoderm sperm toxicity test was used instead of the bivalve larvae bioassay due to the ' unavailability of spawning adult bivalves at the time of the test. The elutriates were tested at 10, 50 and 100%. Disposable scintillation vials containing 5 ml of sample were used, with three replicates per concentration. Adult purple sea urchins were obtained from , Pacific Biomarine, Venice, CA. The sea urchins were spawned by injecting them through the Aristotle's lantern with 1.2 ml of 0.1 M KCI. Sperm and eggs were maintained ' separately and kept chilled. A total of 1,000,000 sperm cells were added to each 5 ml exposure volume. Incubation was at 12 m VC in the dark for 20 minutes. A quantity of 1250 eggs was then added to each vial (a sperm:egg ratio of 800:1, determined previously). The vials were incubated for 20 minutes more and then preserved with formalin. Temperature, t pH, and salinity were recorded at test initiation. A quantity of 100 embryos per vial were counted, recording the number of fertilized and unfertilized eggs. Statistical analysis of the percent fertilization was run using Probit analysis for calculation of the ECso ' and Dunnetes procedure for estimation of dose response. , 2.5.1.1 Citharichthys stigmaeus Test ' Sanddabs were obtained from J. Brezina & Associates, Dillon Beach, CA. Ten fish were placed in each of five replicate containers per test concentration. Test solutions consisted of 8 L in 5 gallon aquaria. The tanks were provided with constant aeration. The test was run ' for 96 hours at a temperature of 16.t 2°C and a photoperiod of 14 hours light and 10 hours dark. Animals were not fed during the test. Temperature, pH, salinity, ammonia, and , dissolved oxygen as well as mortality were recorded daily. At test termination, 15 randomly selected fish were measured to standard length to the nearest millimeter, then , blotted dry and weighed to the nearest 0.1 g. 2.5.1.2 Holmesimysis costata Test ' Juvenile mysid shrimp were obtained from J. Brezina and Associates in Dillon Beach, , California. Test solutions consisted of 800 ml in 1000 ml beakers. The beakers were under constant aeration of approximately 100 bubbles/min. The test waters were evaluated ' using five replicates per concentration with ten shrimp per replicate. The mysids were fed three drops (0.3 mis) of anArlenda nauplii suspension twice daily during testing. The test ' was run for 96 hours at 18 z 2°C with a 14 hour light: 10 hour dark photoperiod. is 1 I I 1 n H Temperature, pH, dissolved oxygen, total ammonia, and salinity as well as mortality were measured daily. 2.5.2 Solid -Phase Bioassays 2.5.2.1 10-Day and 20-Day Flow -through Bioassays Solid -phase bioassays were conducted under similar ambient laboratory conditions as the 96-hour static tests. The tests were conducted at 15 t 2'C. Five replicates per test were tested. In the solid -phase tests, 20 Macoma and 20 Nephtys were tested in ten gallon polyethylene tanks for both test, reference, and control sediments under flow -through conditions. The H. costata for the 10-day study were housed in 100 X 15 crystallizing dishes with 38.1 cm high 50 Nm Nitex collars which were placed in the ten day tanks under flow -through conditions. Confinement in this fashion allowed the removal of the mysids on Day 10 and reduced disturbance of them during set up. Water salinity, pH, dissolved oxygen, total ammonia, and temperature were monitored daily. Seawater flow -through rates were adjusted to 100 ml/min in order to maintain dissolved oxygen levels above 409o' of saturation, as required by the Manual. Nephtys and Macorna were acclimated in a 3.0-cm bed of sieved (1.0-mm mesh) reference sediment for 48 hours prior to the introduction of test material. All three test species were tested together, but the mysids were not placed into the test chambers until after the test material was added. ' At the end of ten days, the Hohnesimysis chambers were removed from the test chambers and the animals counted to determine percent mortality. The sediments in the test chambers ' were then sieved to remove worms and clams, and the percent mortality was determined for each species. LEI FI 2.5.2.2 Rhepoxynius abronius 10-Day Static Test The test procedures for Rhepoxynius varied from the standard 10-day test procedures. The amphipodRhepoxynius abronius were tested generally according to methods described by Reish and LeMay (1985). Test, reference, and Puget Sound (control) sediments were tested. Five replicates of each sediment type were placed in 1000 ml beakers at 18 -t 2°C to a depth of 2.5 cm. The chambers were filled with laboratory seawater and aerated at 100 bubbles/min. Separate crystallizing dishes were set up containing control sediment 19 1 LJ and 20 amphipods. This system was allowed to acclimate for 24 hours.At that point, any dead or surfaced amphipods were replaced, and the amphipods from one dish were placed in each of the five replicates of sediments. The animals were observed to determine if they buried themselves in the sediments. The chambers were maintained under static conditions and with constant illumination and aeration for ten days. Water quality observations included pH, dissolved oxygen, temperature, and salinity. It was necessary to add fresh water to some concentrations during the test to maintain salinity below 35 ppt. Due to the limited volume of the test solution, ammonia measurements were taken on Days 0 and 10 only. At the end of ten days, the sediments were screened and live amphipods were counted. All live amphipods were placed in clean Puget Sound (control) sediment and the number reburying themselves in one hour was counted. 2.5.3 Bioaccumuiation The bioaccumulation study was carried out on surviving Nephtys and Macoma from the 20-day solid phase toxicity study. All surviving organisms were placed in sediment -free, flow -through aquaria for a depuration period of 48 hours. Following the depuration period, the tissues of these specimens were mechanically homogenized and assayed to determine tissue levels of trace elements (arsenic, cadmium, chromium, copper, lead, mercury, zinc, selenium, nickel, and silver), PAHs, total pesticides, total polychlorinated biphenyls, total petroleum hydrocarbons, and oil and grease. 2.6 BIOASSAY QUALITY ASSURANCE PROCEDURES The quality assurance objectives for toxicity testing conducted by MEC Analytical Systems Bioassay Division are identical to those mentioned in U.S. EPA (1985a, 1985b). These objectives for accuracy and precision involve all aspects of the testing process including: (1) water sampling and handling; (2) source and condition of test organisms; (3) condition of equipment; (4) test conditions; (5) instrument calibration; (6) use of reference toxicants; (7) record keeping; and (8) data evaluation. The methods employed in every phase of this toxicity testing program are detailed in ASTM (1980) and in laboratory protocols and procedures. These SON have been approved and placed in the laboratory files. All data collected and produced as a result of this analysis were recorded on approved data sheets which will become the permanent data record for the program. The MECBL quality control manager checks the raw data and study records to ensure that required test conditions are within specifications cited in the standard II I J F I 1 1 I [1 t 20 I� ' operating procedures. Any unforeseen circumstances that may affect the integrity of the ' study are reported with the test results. ' Instruments are calibrated daily according to Laboratory Standard Operating Procedures (SOP's). All calibration data are logged and initialed. The SOP's for the analytical instruments used in toxicity testing are maintained in the Maintenance and Calibration Log. ' The SOPS contain applicable calibration and maintenance intervals, listings of standards to be used, environmental conditions requiring recalibration, units for reporting data, accuracy ' and expected precision. All equipment identification and calibration information were recorded in the Maintenance and Calibration Log maintained at the Laboratory. ' Areference toxicant test, utilizing cadmium chloride was used as an internal quality check of the sensitivity of each batch of test organisms. Water quality measurements were tmonitored to ensure they fall within prescribed limits, and corrective actions (EPA recommended) were taken if necessary. All limits established for this program meet or ' exceed those recommended by EPA and ASTM (1980). The results of each test were compared with laboratory data for this reference toxicant performed on the species, to ' determine if the results are within acceptable limits. ' The performance of key analytical equipment is routinely monitored so that equipment failure that is sometimes preceded by significant changes in operational parameters can be anticipated and often prevented. Procedures used to monitor equipment are included in the ' Maintenance and Calibration Log. ' Stock standard solutions are stored in at least two separate containers, so that a fresh standard solution is always available in case the stock standard currently in use becomes contaminated. Working standards which are in frequent contact with electrodes, pipets, etc. are kept in separate working bottles to reduce chances of contamination of stock standards. The precision of the LC50 determinations were shown by calculating the 95 percent confidence intervals. The computer program used to analyze the data is designed in such a way that regardless of the data characteristics, it will calculate an LC50 and the corresponding confidence intervals. Accuracy cannot be determined as a true value but rather must be determined relative to a reference value of the pollutant being measured. 21 Finally, the precision of all the analytical instruments (D.O. meter, pH meter, balances, ' etc.) is assumed to be that stipulated by the manufacturer. The accuracy of the , measurements is assessed through calibration each time the instruments are used. 2.7 STATISTICAL METHODS At the conclusion of the tests a statistical evaluation of survival and development is , performed using Dunnett's test (ANOVA) with Bonferroni's adjustment. An effeci on mortality or development is considered to be a statistically significant difference (P a 0.05) , between the mean survival or development values for the test organisms and the mean values for control or reference organisms at the end of the test (EPA,1985). ' The No Observed Effect Concentration (NOEC) is the highest exposure where no adverse ' effects on survival and development were observed. The Lowest Observed Effect Concentration (LOEC) is the lowest exposure where statistically significant effects on the test species were observed. The Maximum Allowable Toxic Concentration (MATC) is the ' geometric mean of the NOEC and the LOEC and is considered the toxic threshold concentration. The lowest NOEC values of the two tested effects is reported as the NOEC , for the test. Percent survival is based upon the total number of animals surviving in each test, reference , or control compared to the initial counts. The LC50 value is based upon the analysis of the treatment mortality as a dose response. 2.8 CALCULATION OF THE LIMITING PERMISSIBLE CONCENTRATION , The LPC is estimated using methods described in the EPA/ACOE Manual (1977). The ' analysis is carried out for three different barge configurations. 1 I LJ d 3.0 RESULTS Summaries of the results of the chemical analysis and bioassay tests, are provided in Tables 3-1 through 3-6. Complete bioassay data are in Appendix A. The analytical laboratory reports are included in Appendix B and the quality control documentation is in Appendix C. 3.1 SEDIMENT PHYSICAL AND CHEMICAL CHARACTERISTICS Sediment Chemistry Sediment chemistry is presented in Appendix B and a summary of data is presented in Table 3-1. Reference Site. The chemical analysis of the reference sediments taken from offshore of Newport Beach are presented in Appendix B, and are summarized in Table 3-1. The sediments' constituents are generally similar to those taken from the same location for previous bioassays in the Newport Beach area. Heavy metal levels were found to be similar to the test sites for most constituents with chromium, nickel, cyanide, zinc and arsenic being higher in the reference sediments. Test Site 1 The analysis of sediments from Test Site 1 revealed moderate levels of lead, ' chromium, and mercury. Total petroleum hydrocarbons, grease and oil were low. A small amount of DDE and Endosulfan sulfate were found as well as an elevated level of PCB ' 1260. No PAM were found. Phthalates were found at 154 ppb. Site 1 also had a low percentage of total organic carbon (1.35%). P Test Site 2. The analysis of sediments for Test Site 2 were generally lower for most constituents than Test Site 1. TOC was low (0.206%). No pesticides, PCB, PAH, or phenols were found. Phthalates were found at 139 ppb. Test Site I. The analysis of sediments for Test Site 3 showed higher levels of most metal constituents tested compared to Test Sites 1 and 2. Endosulfan sulfate and DDE were identified. TOC was high (2.255%). Tributyltin was found at 26.6 ppb. Phthalates were found at 208 ppb. 23 3.2 GRAIN SIZE ANALYSIS The analysis of grain size for the reference and test sites was carried out by NEC Analytical Systems and are shown in Table 3-1. The reference sediments were 4.2% sand, 34.99 silt, and 60.9% clay. Tbst Sites 1, 2, and 3 had coarser grained sediments than the reference sediments. All test sites included gravel, up to 7.49o. 3.3 LIQUID/SUSPENDED-PARTICULATE PHASE BIOASSAYS 3.3.1 Test Results Strongylocentrotus yurnuratus . Control fertilization was 85.896. This level of fertilization is within the limits (70% fertilization) set by the EPA (1988). Water quality parameters were within the appropriate limits. The results of the S putpuratus test are in Table 3.2. Statistically significant effects on fertilization were detected at 10, 50, and 100% for Tests 1 and 3 and at 50 and 100% for Tbst 2. The LC50s were 52.3%, 83.6%, and < 100,10 respectively for Tests 1, 2 and 3. Holmesbnvsis costato. Water quality parameters in the test were within established limits. The results of the 96-hour USP phase bioassay on Hohneskysis costata are presented in Table 3.3. Control survival of mysids in laboratory seawater was 94%. This was higher than the 907* minimum established by the ACOE for invertebrates in dredge bioassay tests. There were no significant effects on mortality for any of the test sites. The NOECs were 100% and the LC50s were > 1007o. Citharichthvssikmaeus. Water quality in the C. stigtnaeus 96-hour bioassay was generally within the limits established by the Manual. Dissolved oxygen levels were above the limit of 4.0 mg/L. The results of the C stigtnaeus bioassay are presented in Table 3-3. Survival in the control replicates was 1009o. No significant effects on mortality were observed for any of the test sites. The NOECs were 100% and the LC50s were > 100%. I H n n 1 11 I 0 24 J ' 3.4 SOLID PHASE BIOASSAYS 3.4.1 Test Results ' Rhepoxvnius abroniu . Water quality in the 10-day Rhepoxynius solid phase bioassay was good even though it was conducted under static conditions. Temperatures were 18 ' 2°C. The salinity was elevated above 35 ppt in some replicates because of the static conditions and the constant aeration. The salinity was lowered to below 35 ppt in these ' chambers by the addition of spring water. Chambers were aerated and dissolved oxygen remained high. The control water quality measurements were missed on Day 0 as was ' salinity in some replicates on Day 4. A summary of results for the amphipod test is presented in Table 3-4. ' Survival of the amphipod in the reference sediment was 66%. Survival in the control sediment was 99%. The reference organisms showed 93.996' reburial and the controls ' showed 100% reburial. Neither mortality nor reburial was significantly low for any of the test sites. I H Holmesim stv 's. NephW, and Macoma. In the 10-day solid phase toxicity study on H. costata, N. caecoides, and M. nasuta, the test system was under flow -through conditions. Laboratory seawater was pumped to the test system and dispensed at a rate of approximately 100 ml/min or an exchange rate of 7.2 tank volumes per day. Water quality in the test container therefore is a function of the ambient seawater quality. Daily water quality measurements were taken in all chambers. Ammonia was measured in chambers 1 and 4 for each set of replicates. Water quality during this study was excellent. Temperature was maintained at 15 = 2°C, dissolved oxygen levels were above 4090 saturation. All of the test animals were maintained in the same system and the water quality conditions were appropriate for all of the tests. A summary of the results of the 10-day solid phase bioassay is presented in Table 3-4. Hohnesimysis costata survival in the reference sediments was 65%. Survival in the control sediments was 95%. Mortality was statistically significant from the Reference site in Test Site 3. Nephtys caecoides. Survival of worms in the reference sediment was high (92%). Survival in the control sediment was 90%. Mortality was statistically significant for Test Site 2 with 79% survival. No significance was determined for Test Sites i and 3. 2s I Macomanasuta. Survival in the reference sediment was 98%. Survival in the control ' sediment was 97.5%. Mortality was not significant for any of the test sites. ' 3.5 BIOAccumu ATION TESTS Bioaccumulation of trace metals and toxic organics by clams and worms held in the ' reference and test sediments was compared on the basis of replicated chemical analyses performed on the tissues. The results of the statistical analysis of M. nasura and ' N. caecoides are summarized in Tables 3.5 and 3.6. , 3.5.1 Test Results The data for Appendix A water quality the 20-day bioaccumulation test are presented in Table 11.

' Test Site 2 Bioaccumulation of three chemicalconstituents was found to be statistically significant. Cadmium, oil and grease, and TRPH were 3.5, 2,7, and 3.4 times their respective reference levels. Test Site 3 ' Bioaccumulation of four chemical constituents was found to be statistically significant. Cadmium, copper, TRPH, and oil and grease, were found to be 4.1, 2.1, 1.8 and 1.6 times their respective reference levels. ' 26 ' 0 ' Bloaccumulation in Macoma ITest Site 1 ' Bioaccumulation of chromium was found to be statistically significant, with the mean test value being 1.5 times the reference levels. ' Test Site 2 ' Bioaccumulation of five chemical constituents was found to be statistically significant. ' Chromium, copper, mercury, selenium, and silver were found to be 9.5, 2.2, 4.3, 1.02, and 1.2 times the respective reference levels. The comparisons between the reference and test animals for mercury, selenium, and silver were done primarily using detection limit ' values and should be viewed with caution. ' Test Site 3 ' In Test site 3, chromium and 4,4' DDE were found to be accumulated at a statistically significant level. Chromium levels were found to be 1.4 times the reference and DDE was 9.8 times the reference. 1 1 TABLE 3.1 SUMMARY OF SEOIME.\T CHARACTERIZATION Doteetla Sits 1 2 3 Referthea Limit Greta Azo M Orwal 3.4 7.4 1.9 SW $1.7 612 29.0 4.2 Sim 4.4 OS 12.9 34.8 Clay 35A 30.9 60.9 609 Sellia (R) (Dry WL) 70.0 $0.0 60.1 46.2 Total Ocpelc Cathem (R) 135 02" 2259 7.149 BdOdtt (sem) Taal 224 5510 752 75.8 MYr $omit (du flute) 031 ON 0.17 0.11 0.1 Ona ill, (ue/ka) 7flMgith < 1.43 < US 26.6 < 2.16 1.0 DiMrytuh < L43 < IM < L66 < 216 1.0 k(uabmplue < L43 < 1.25 < L66 < 2.16 1.0 c1b" Waal (6101,14m) 64116,81 L73 .932 91.2 0.10 Oteue R 04 0") 29.7 < 126 44.9 U.) 30 TAPH(ppm) 29.7 < 12! 449 31.9 Metals (mNke) Cadmium(Cd) 0.480 <0.124 0.877 0.420 0.1 Chromium (Cr) 4.91 1.39 8.04 20A5 CopKP) 16.13 3.29 253 22.5 tad(Pb) 211 218 23S LS3 nut (1i) 5.36 208 9.68 LS.43 Sdacr (AS) 40.029 < 0.02S < 0.033 < 0.043 0.02 Lee (7n) 21.1 3.44 37.4 15.79 Metals (At) 2.46 1.73 3.31 3.S9 Y-=701W 0323 <0.015 0.14S <0.043 0.02 Stkarvm(SC) <0.143 40.124 <0.166 <0.216 0.1 PeSalddo aad PCB, (ualkal 0-DDD 1D ND HD HD 2 4.4'•DDE 14.7 ND 39.1 14) 2 4C • DDT NO 1D 1D 1D 2 Aid& 1D 10 1D tiD 2 A"&.BHC ND 1D 1D ND 2 Hen BHC ND 1D ND ND 1 Chkrodtoe 1D to 11) 1D 2S DOM BHC 1D 1D ND No 2 Oitidm NO M) 1D ND 2 Padmitan I ND 1D 1D 1D 10 EadmalOe B 1b 10 1D 1D 2 Eodmultm Sulfam 3.4 1D 7.0 ND 2S Eadtfa N) HD 1D 111) 2 ED" Aide" ND ND ND ND 10 Heprtchim 1D 1D 1D 1D 2 114puchlor EpuWe 1D ND 1D 1D !0 Oammt•BHC NO ND ND 1D 2 7bupbea4 1D NO 111) NO 25 PCB 1016 ND ND NO 173 50 PCB 1211 %D ND NO IND 50 PCB 1232 ND 1D %10 1D 50 PCB 1241 1D 1D 1D 11) $0 ?CB 1248 ND HD ND 1D $0 PCB 1234 NO 1D ND ND 50 PCB 1260 200 1D ND 1D SO (1) AN chemical aaallme me liven u dry xeiSht heels.

Y=Yes N=No 33 r 4.0 DISCUSSION ' 4.1 SEDIMENT CHEMISTRY I The results of the chemical analysis of the three test site sediments and the reference , sediments indicate that the test sediments have moderately elevated levels of heavy metals when compared to the reference site. Polynuclear aromatics are not detected at any test site ' or the reference site. 'There are detectable but low concentrations of pesticides and PCBs (DDE (Sites 1 and 3), Endosulfan sulfate (Sites 1 and 3), and PCB 1260 at Site 1. Test Site 3 had the highest overall levels of most metal chemical constituents. The ' reference site had elevated levels of cyanide and some of the heavy metals were within the range of values observed at the three test sites. 4.2 BIOASSAX RESULTS 4.2.1 Liquid/Suspended Particulate Phase ' Based upon the three tested species some toxicity was observed in the 4:1 elutriate only in ' the sea urchin test. The lowest ECSO was found at Test Site 3 (< 10%). Site 1 had an EC50 of 52.3%, Site 2 was 83.6% elutriate. The limiting permissible concentration (LPC) was calculated (Table 4-1) for all test sites. Based upon the results of this analysis no , significant short-term effects would be expected from the disposal of this material at the ' IA-3 disposal site. The almost instantaneous dilution at this deep site effectively reduces the potential for short term toxic effects. 4.2.2 Solid -Phase Toxicity In the 10-day solid phase test, Xohnesimysis showed significant mortality (629o) in the test , sediments only from Site 3. In comparison, mortality at Sites 1 and 2 was 41% and 32% respectively. Grain -size was significantly higher in the percent clay at Site 3. This level of toxicity has been observed in other bioassays because this species is essentially a planktonic species and may not be the best species for a solid phase test since it tends to ' respond to grain -size as well as toxicants. Furthermore, Nobnesimysis had only a 65% survival in the reference site sediments (60% clay), in contrast to 95% survival in control ' 34 1 sediments (sand). It is anticipated that eitherNeomysis or Mysidopsis may be substituted in future testing since they occur normally at the sediment interface. Mortality inNephrys was marginally significant in Test Site 2, but not significant in Site 1 or 3. MortaIity was not significant at any site for Nephrys at 20 days. No significant mortality was found for Macoma in either the 10 or 20 day testing. Survival ofRhepoaynius was not significantly lower in either test site sediments than in the reference sediment and control reburial was not significantly affected. Based upon these results, there would appear to be low potential for long term toxicity to the mysid and the worm and no significant potential for long term effect on the amphipod or clams. 4.2.3 Bioaccumulation The results of the bioaccumulation testing of the clams and worms in the test site sediment appear to indicate a relatively low potential for significant bioaccumulation at the disposal site from the discharge of this dredge material due to the low bioaccumulation factors observed. ' In •Nephtys, significant bioaccumulation was found in all test sites. Bioaccumulation factors ranged from 1.6 (oil and grease, Site 3) to 4.1 (cadmium, Site 3) above reference ' levels. In Macoma, bioaccumulation was found at all three sites. Bioaccumulation factors ranged from 1.02 (selenium, Site 2) to 9.8 (DDE, Site 3). The comparisons for selenium, silver mercury, and DDE were conducted using detection limits and should be viewed with ' caution. 4.3.4 Summary The chemical composition of the sediments in the three test sites appears to be moderately ' elevated above the reference site, although a number of constituents are higher at the reference site. These include chromium, nickel, cyanide, zinc and arsenic. Organic constituents appear to be low, including pesticides, PCBs, PAH, phenols and phthalates. The results of the bioassay do document some toxicity in the sea urchin sperm inactivation test in the liquid/suspended phase testing. This is a relatively new species to be used in 35 1 I dredge material testing and no substantial data base has been established for its performance ' in liquid/suspended particulate extracts. The calculation of the Limiting Permissible Concentration carried out using the EC50 data and grain size data is not exceeded primarily due to the mixing potential at this deep site. ' In the solid phase, mysids had a statistically significant increase in mortality at Test Site 3. The survival in the reference site was low as well. This species does not appear to work effectively when tested in fine grain -size sediments. ' In Nephtys, survival was reduced significantly in Thst 2 sediments at 10 days. However in the 20 day test, the Test 2 replicates did not have any significant mortality. The reason for t the mortality at 10 days is not clear. Water quality parameters were within limits. No toxicity was observed to Macoma at any test site at 10 or 20 days. Tn the bioaccumulation testing, some statistically significant bioaccumulation was found at all the sites. The actual tissue levels were relatively low and often significance was based ' upon small differences between the reference and test means. 3ioaccumulation factors ranged from 1.02 to 9.8 times the corresponding reference levels, Several significant tests were based upon the statistical comparison of detection limits and should be viewed with , caution. Overall, these test sites appear to have a relatively low potential to significantly degrade the LA-3 disposal site. 1 36 1 TABLE 4-1 Calculation of the Limiting Permissible Concentration Site: Test Site 1 M.

Food and Drug Administration (USFDA) has issued action levels and tolerances for harmful substances in edible portions of shellfish (USFDA 1985). These are limits at or above which USFDA will take legal action to remove affected fish or t shellfish from the market. The USFDA has stated that these limits are set "... based on the unavoidability of the poisonous or deleterious substance and do not representAction specified in Title permissible levels of contamination where it is avoidable" (USFDA 19821 levels were established and revised according to criteria on level is Code of ' Federal Regulations, Parts 109 and 509 (21 CFR 109 and 509). An actio revoked when a regulation establishes a tolerance for the same substance and use. To date, only PCBs in fish and shellfish have had a tolerance established by regulation. ' Table 4 lists the action levels and the tolerance set by the USFDA as of January 1985, for those substances that are monitored by SMW. Table 4.

' Source: Stevens 1988 ' SMW 1986-87 - 7 V 7 r r: NAS GUIDELINES The National Acad f S ' NAS emy o dances (. ) has recommended maximum concentrations for toxic substances in animals (NAS 1973). These guideline leyell were developed to protect both the animals containing the toxic substance and any , predators or consumers of those affected organisms. The NAS has set recommended r guidelines for marine fish, but not for marine shellfish. However, two of the \qs . recommendations do apply to freshwater clams. These are listed in Table 4. DHS HEALTH ADVISORY LEVEL , Previous State Mussel Watch reports have cited a Department of Health Servicts (DHS) "health advisory level" of 0.5 parts per million (ppm) fresh weight for total mercury in the edible portions of sport -caught fish and shellfish. If the mercury content of fish or shellfish regularly exceeded that particular level, DHS has in specific incidences issued health advisory warnings (published yearly in the California Fishing Regulations) against consumption of contaminated species at specific locations. Recently, DHS staff has notified State Board staff that no formal health advisory level for mercury exists, and that advisories are issued on a case -by -case basis, depending on site conditions and other factors. Therefore, all references to a DHS health advisory level have been omitted from the following sections of this report. CALCULATED MEDIANS OF INTERNATIONAL STANDARDS Excluding methyl mercury (USFDA), there have been no United States standards for trace metals in shellfish. As a result, it has been difficult to judge the significance of much of the SMW trace metal findings in terms of human toxicology. The calculated MISs that have been set by other countries have therefore been useful reference values to evaluate SMW findings, These NJIS values (Table 5) are not enforceable in the United States, but they do provide an estimate of what other countries have decided are undesirable concentrations of trace elements in shellfish. See Appendix F for further elaboration on medians of international standards and the data used to calculate them. Table S. Medians of International Standards for Trace Elbments in Shellfish'.

The purpose was to identify the marine biological resources ' present in the proposed Castaways marina project area and the presence of any significant biological resources. Laboratory analyses and data reduction were performed by MBC Applied Environmental Sciences, Costa Mesa, California. ' Field Survey Methods. Benthic samples were collected by MBA biologists using scuba apparatus at three stations: B-1, B-2, and B-3 (Figure 1). At each station, five-1 liter (0.01 m2) sediment samples were collected with a diver operated box coring device. Samples were returned to the ' surface, and benthic infaunal core samples were washed through a 0.5 mm mesh screen. The animals and shell material retained on the screens were then placed in pre -labeled plastic bags, and preserved in a 5 percent formalin solution for later laboratory analysis. ' Two 2.5 cm 10 cm core samples were collected for sediment grain size analyses. Divers inserted the PVC core tubes to the sediment, capped both ends, and placed them in a collecting bag. On the ' surface, the sediment samples were transferred from the core tubes directly into pre -labeled plastic bags, and stored for laboratory analyses. 1 u 0 Following the collection of benthic samples, biologists conducted a subtidal reconnaissance of the project area to determine if significant biological resources were present in the project area. The survey consisted of two sets of five underwater transects, run at a 45 degree angle to the shoreline between the depths of -1 and -10 feet below MLLW. The types of intertidal mudfiat and rocky intertidal organisms were also assessed during the low tide of the day. The presence of these organisms was noted and qualitatively assessed for their relative abundance. Laboratory Analyses and Data Reduction. In the laboratory, the biological core samples were washed on a 0.5 min mesh screen, and transferred to a 70 percent isopropyl alcohol solution 24 hours after the field survey. Organisms were sorted from the debris and identified to the lowest possible taxon currently recognized, with the aid of dissecting and compound microscopes. Computer data printouts were generated for each benthic sample replicate, and summarized by station. Station data included a master species list and a station summary that provided total, mean, and standard deviation for species abundances, numbers of species, Shannon -Wiener Species Diversity (H'), Pielou's Eveness (T), and Marglaef's Species Richness (d). All calculations were made using natural logs. Data analyses were subsequently completed by Michael Brandman Associates. The replicated sediment samples collected from each station were composited into a single sample for determination of particle size fractions and mean grain size. Samples were first treated with hydrogen peroxide for organics, and then desalted. Hydrometer and sieve analyses were conducted to determine the percentages of gravel, sand, silt, and clay. Resulting data from the hydrometer and sieve analyses were plotted on a cumulative percent curve to derive values needed to calculate mean particle size. Results. Benthic data by station is presented in Table B-1. Sediment data by station is presented in Table B-2. I Table B-1 Castaway May, 1989 Station B1 PERCENT CUM, PHT SPECIES Ri R2 R3 R4 RS 70TAL //SO. M.

[J 1 r I IINTRODUCTION TO FLORAL AND FAUNAL SURVEY 1 Floral components encountered during the survey were recorded in terms of relative' abundance and 1 host habitat type. Expected site use by wildlife is derived from survey information combined with documented habitat preferences of iegional wildlife species that, whether or not recorded during the survey, are considered likely to include the project area within their range. Habitat designations used in this report are according to the classification system of Holland (1986). Floral taxonomy used in this report follows that of Roberts (1989), Raven et al. (1986), and Beauchamp (1986). Common plant names, where not available from Roberts or Beauchamp, are taken from Munz (1984) and Abrams (1923). Vertebrates identified in the field by sight, calls, tracks, scat, or other signs are cited according to the nomenclature of Jennings (1983) for amphibians and reptiles, IAOU (1983, 1985, 1987, 1989) for birds, and Jones et al. (1982) for mammals.

BECKER PRINCIPAL INVESTIGATOR: RONALD M. BISSELL 16 AUGUST 1989 I ' MANAGEMENT SUMMARY ' An archival search and field reconnaissance determined that three archaeological sites and one area of archaeological sensitivity ' exist within the boundaries of the Castaways Marina project. ' The three sites and the archaeologically sensitive area contain both prehistoric and historic deposits. CA-Ora-48 is an extensive shell midden. Its subsurface extent is unknown. CA- ' Ora-49 is a shell midden which exhibits a well developed stratagraphic profile. Its lateral extent is unknown. CA-Ora- 186 is a multicomponent site consisting of both historic and prehistoric components. The historic components may relate to� ' the Newport Landing and later Orange County Country Club phases. The entire project parcel is an area of archaeological ' sensitivity and -may contain subsurface material which relates to the Newport Landing. It is recommended that a program of archaeological test excavator be undertaken to determine the extent, depth, degree of ' preservation and significance of the sites. Additionally, the area of archaeological sensitivity should also ' . be subjected to a program of test excavation to determine the existance of a historic site. Subsequent actions will be ' determined by the results of the test excavations.

The study area consists of a project parcel of approximately four acres, and an adjacent dredge material disposal site of approximately 50 acres. The boundaries of the entire study area are Dover Drive on the west, Upper Newport Bay on the east, Pacific Coast Highway (State Route 1) on the south and a housing development on the north. A portion near the center of the property is occupied by the Newport Harbor Lutheran Church, and is not included within the scope of this study. The approximate boundary of the study area is -shown on the Index Map which appears on page 2 of this report. The study area is located on that part of the eastern side of the Newport Mesa which adjoins Upper Newport Bay. Here Newport Mesa drops abruptly to the bay. Topographically, the dredge material disposal site is quite flat. The elevation of most of the parcel is about 80 feet. The project parcel situated in the extreme southern portion of the study area is separated from the disposal site by a steep bluff. It is located at an elevation of 15 feet. Overall, it too, is flat. The bulk of the surface of the entire study area is comprised of loose, silty,'well developed alluvial soil. Most of the vegetation found within the study area boundary consists of introduced grasses. Stands of eucalyptus trees have been planted along the eastern edge. Also, just above the bluff which leads down to the project parcel, there are several introduced trees and shrubs. Most notable are two palm trees and one unidentified coniferous tree. 1 1 /.� ',',+„rt��.•„`,+irc �� ,I � ' `iiii l•+.. jr if VWKW�71�7 INDEX MAP: A portion of the USGS 7.5 minute RMW Newport Beach quadrangle,1965.

' Disturbance in the study area ranges from minimal to profound.. The most heavily disturbed area is the project parcel itself. The disposal site shows much less disturbance. 1 1 Although -the resources found immediately within the confines of the current study area are limited, the parcel's location does provide for easy access to several diverse vegetation communities and the corresponding ecotones which they comprise. The ease with which these resources could have been exploited would have made this area quite attractive for habitation by prehistoric ' peoples. 1 1 CULTURAL SETTING The cultural history of the surrounding area is a topic of long standing. To date, three landmark papers have appeared which discuss the local chronology. Wallace (1955) was the first to synthesize the available data into a workable scheme. By 1968 a considerable number of radiometric age determinations were available and Warren utilized them to develop a major revision of Wallace's chronology. The latest work is that of Koerper and Drover (1983). The work of Koerper and Drover is based primarily on extensive excavations at CA-Ora-119-A, a large multi -component site in the Newport Bay area of Orange County. A multi -component site is one which contains evidence from more than one cultural period. In'the case of CA-Ora-119-A there was evidence from very early times to recent'historical deposits. 3 1 D FIGURE 1: CHRONOLOGY.

Basically, each paper represents a refinement of the chronology based on increased knowledge. There are, however, two major exceptions to this statement which must ' be mentioned. First, Wallace used general descriptive terms for naming the various cultural periods in his chronology. Warren ' used terms which were much more restrictive in a geographic sense and much less self explanatory. Koerper and Drover have returned ' to the period names as established by Wallace. ' The second exception has to do with defining the boundaries between cultural periods. Wallace's paper gives'the impression of rather sharp delineations between periods, whereas Warren ' recognized that cultural change occurs slowly and at different times and rates in different areas. Accordingly, he replaced ' Wallace's term for cultural periods, Horizons, with the term Traditions. His definitions provide for cultural sequences which ' grade into each other and allows traits to persist longer in some areas than in others. ' Figure 1 on page 4 is a summary of the local chronology as it is presently understood. Figure 1 is based primarily on the work of Koerper and Drover. It must be understood that the figure relates only to a restricted geographic area and that the ' temporal boundaries are not as clearly defined as the figure indicates. ' The time when man first appeared in the local area is not clear-. There is good evidence that man was present in the local area by ' the end of the Pleistocene, some 10000 years ago. These people represent the Early Man Cultural Period, which persisted until ' about T500 B.C. The people of the Early Man Period apparently 5 1 1 I subsisted primarily by hunting. Certainly, the artifacts available from this ancient time indicate a hunting subsistence pattern. It would have been nececessary for the Early Man people to move quite frequently as game in a given area became exhausted. Such a life style, exploiting only a small fraction of the available resources, would not have been capable of supporting large numbers of people, so the population was probably quite small. Since only the lithic tools have survived from these early people, very little is known of their total culture. The Milling Stone Period, which began during the centuries around 7500 B.C., saw a major change in subsistence strategy. Tools for the processing of hard seeds appear in large numbers for the first time. These tools, known as manos (the hand held stone) and metates (a larger stone against which the seeds were ground), permitted exploitation of a wide range of vegetable resources. Chipped lithic tools such as projectile points, which exhibited great care in manufacture during the Early Man Period, are now much more crudely made. Certainly, hunting continued to play a role, but the gathering of hard seeds apparently played the major subsistence role. The Milling Stone adaptations were apparently quite successful, since the culture persisted in essentially unchanged form for several thousands of years. The people of the Milling Stone Period were also wanderers, moving frequently throughout the year to take advantage of resources which ripen at varying seasons depending on the elevation, distance from the coast and other factors. However, the pattern of wandering was quite different from that of the Early Man Period. The Early Man people were destined to follow the game herds wherever they went, but the Milling Stone people could follow the same general course 0 C 1 1 1 F 1 1 1 u 1 1 1 i 1 1 1 1 I 1 I I U I 1 I H from year to year. Often they would occupy the same camp sites during the same season over a period of many years. The Intermediate Cultures Period followed the Milling Stone, beginning about 1000 B.C. and persisting until about A.D. 750. The Intermediate is not well understood, primarily because it was a period of rather rapid cultural change and differentiation into smaller groups, each with its own set of cultural characteristics. The introduction of the mortar and pestle (grinding tools which use a pounding action rather than sliding) allowed the exploitation of the acorn as a food resource. Due to its ready availability and quantity, the acorn rapidly became a staple. This shift permitted a more settled life style. Large, apparently permanent encampments are first in evidence during the Intermediate. The old Milling Stone culture, which covered a wide geographic area, began to differentiate into smaller cultural units during the Intermdiate, and each of the smaller units began to develop its own cultural features. The use of steatite (soapstone or talc) began during the Intermediate. Since the only known local sources of steatite are on Catalina Island, it is clear the Intermediate people had mastered the techniques required to cross rather wide expanses of open ocean. The reduction in size of projectile points during the Intermediate is an argument that the bow and arrow were first used during this period. The Late Prehistoric Period is the final archaeological phase, ending with Spanish contact. This period saw the completion of the process of differentiation into tribal units, each with its own distinctive set of cultural traits. The tribal group which lived in the vicinity of the study area were known as the Gabrielino. The name derives from mission association and was 7 I I I bestowed by the Spanish. The name the indigenous people used to identify themselves is not certainly known. Pottery appeared near the end of the Late Prehistoric Period. The Gabrielino apparently controlled the trade in steatite and the bulk of that material is found in their area. Since steatite and pottery served much the same purpose, there is less pottery found in the Gabrielino sphere of influence than in surrounding areas. ' The life style of the Late Prehistoric people was more settled ' than was the case during earlier periods. The exploitation of a wide range of subsistence resources permitted permanent encampments, which sometimes contained as many as several hundred people. The connection between the people of the. Late Prehistoric Period and earlier cultures may not be direct. The Gabrielino language is derived from the Tackic family which originated in the Great Basin area, far to the northeast. Hokan speakers are found to the north and south of the Gabrielino, Juaneno and Luiseno. The Juaneno and Luiseno are tribes found to the south of the Gabrielino, but with broadly similar cultures. The implication is that the area was once filled with Hokan speakers who were displaced by migrants from the Great Basin. The timing and ' extent of the migration is in dispute, but it may have began as early as 500 B.C. and continued until shortly before Spanish ' contact (Bean and Smith 1978). The historic period in Orange County opened in 1542. It was in , this year that Juan Rodriguez Cabrillo, while sailing along the 8 ' �J I 1 Southern California Coast, is believed to have seen what would later be known as Orange County. On 23 July 1769 the overland expedition headed by Gaspar de Portola entered Orange County. -In the company of this expedition was a man named Jose Antonio Yorba. He later came to be a landowner through the Spanish land grant of Rancho Santiago de Santa Ana. There was no permanent settlement in Orange County until the'founding of Mission San Juan Capistrano on 1 November 1776. The first presumed historic use of what is today called Newport Bay was in 1810. In that year Jose Antonio Yorba and Juan Pablo Peralta received the Newport Mesa and the western mainland shoreline of Newport Bay as a result of the Spanish land grant of Rancho Santiago de Santa Ana. The Upper Newport Bay and most of the mainland shore of the lower bay were granted to Jose Andres 1 Sepulveda through the Mexican land grant of Rancho San Joaquin. This land grant was actually the result of two separate grants: Rancho Cienega de las Ranas on 13 April 1837 and Bolsa de San Joaquin on 13 May 1842 (Friis 1965, Cleland 1962). The first attempt by the United States Coast Survey to examine Newport Bay was in 1860. In September of that year., 'the U.S. M Coast Survey Schooner Humbolt anchored off the'Newport-Balboa peninsula. William E. Greenwell disembarked from the vessel and rowed into Newport Bay. Upon returning to the Humbolt, Greenwell commented on the difficulty he experienced in trying to navigate through the -surf into the bay. While trying to consolidate their real estate holdings in the area, James Irvine, Benjamin Flint, Thomas Flint and Llewellyn 9 I I Bixby, all partners, became the owners of the properties surrounding Newport Bay. This was accomplished in two ways. In 1864 they purchased Rancho San Joaquin from Sepulveda. Then, on 12 September 1868 they received, as a result of a favorable judgement in the case of Abel Stearns et al. v. Leonardo Cota et al., a portion of Rancho Santiago de Santa Ana. The piece of property they acquired was a strip of land bordering Newport Bay. In 1876 Irvine bought out his partners and became the sole owner of the lands around Newport Bay (Cleland 1962). 1 The first merchant vessel to enter Newport Bay was the Vaquero. There is some dispute in the records regarding when it first entered. Sherman claims that the vessel was entering the bay as early as 1865. The accepted date of its first entry, however, is ' 10 September 1870. it was on this day that Captain S. S. Dunnels entered the bay and put in at the beach which would later be called Newport Landing (Lee 1973). Prior use of this beach area has been documented by Lee. Quoting , from Rice, she argues the case that the beach was used by Mexican fishermen for manufacturing oil from locally caught sharks. In 1870, "Flint Bixby Irvine and Company applied for a wharf franchise at the shark fishermen's beach" (Lee, 1973). On October 14 of that same year they also filed maps of two proposed townsites in the area. The names of these two sites were recorded as Newport and Wallula. Each townsite was to contain sixteen lots each. Newport was located in today's Bayerest subdivision. Wallula, which was never developed, was situated on the bluff, "just above the location Dunnells had chosen for his landing" (Lee, 1973). 10 I LJ i 1 In 1872 a small dock was built on the beach and a warehouse on the bluff. Exactly who built the dock is uncertain. Pleasants states that it was owned by D. M. Dorman and Captain Daniel. However, Lee claims that it was Captain Dunnels who is 1 responsible for it. To further complicate matters, two other sources refer to this landing as being built by Dorman and Daniels (Sherman) and by Dorman and Dunnels (Leadabrand). It may be that Daniels is a corruption of the spelling of Dunnels. This dock and warehouse were purchased by James and Robert McFadden in 1873. With the arrival in 1875 of their newly• purchased steamer "Newport," the McFaddens became involved in shipping lumber to Newport Landing from San Francisco. Many agricultural products produced in the vicinity were then loaded aboard for the return trip. A drawing in "Newport Bay" shows the warehouse on the bluff. It appears to be a multileveled structure with the top level providing access to the mesa above the bluff. Extending from the lower level was a hinged chute. This extended into the bay to facilitate the loading of the Newport. Cargo was unloaded from wagons on the mesa and sent ' down the chute directly into the hold of the ship (Lee 1973). Newport Landing was in operation until the McFaddens moved to their newly constructed ocean front facility in 1889. Several of the houses and other buildings were floated across the bay to the new "outside landing." What became of the rest of the facilities at the old landing is uncertain. In 1914 the clubhouse of the Orange County Country Club was formally opened on the bluff directly above the site of Newport Landing (Newport News, 22 August 1914). It was claimed that, "There is no country club anywhere in the west that will compare 11 I with the one on Newport Bay" (Newport News, 1914). As grand as the country club was claimed to be, its location was moved shortly after being built due to a need, "For a larger golf• course" (Newport News, 1956). After the,country club moved, the building was leased for various enterprises. By 1941 a bar and restaurant in the building was known locally as the "Cliff House." The exact nature of the business was uncertain. The following quote from Clinton H. Roemer illustrates the colorful reputation it had acquired. It was reached by a winding dirt road that was not lit at night, nor do T believe that the house was lit from the outside --- one had to know it was there. Some of the Rendezvous musicians went there after the night's jam sessions --- the bar was still open after the legal 2 AM closing. My recollection is that there were more cars in the parking lot than there were people inside. This place was known as the Cliff House, and it well might be that there was gambling or some such other illegal activity taking place on the second floor of the establishment. A review of vintage photographs of the area reveals pertinent information not found in the literature. A photograph dated 1927 shows the original Pacific Coast Highway and Newport Bay Bridge as skirting the bottom of the bluff below the country club. Structures are visible .on the bluff (Smith 1981, P. 56). Another photograph dated as "late 1930's" shows many buildings on the beach of the former Newport Landing. The Pacific Coast Highway is not shown in the same location as in the 1927 photograph (Lee 1973, p. 44).. This picture was obviously taken after the Pacific Coast Highway had been relocated. A 1964 photograph reveals that by that time, a trailer park or some similar development was located on the Newport Landing site (Orange County). 12 I I I 1 lJ I I L� 1] Newport Bay has also been known as: Bolsa de Gengara, Bolsa de San Joaquin, Cienega de las Ranas, San Joaquin slough, San Joaquin Bay and Gospel Swamp. Newport Landing has*been referred to as: Mexican Beach, Port Orange, McPaddens' Landing and the Old Landing. The bluff above the landing is known today as Castaways Bluff. PRIOR CULTURAL RESOURCES RESEARCH A review of the literature at the Archaeological Survey, University of California, Los Angeles (ASUCLA) revealed that the Castaways Marina property had previously been examined for cultural resources. However, no report was ever filed with the ASUCLA. And the results of that study are, therefore, unknown at this time. The records on file did indicate that the project lies within.an area of extreme archaeological sensitivity. Pour archaeological sites are known to exist within the boundary of the current study area. These four sites are described below: CA-LAn-48: This site was first recorded by J. Briggs on 26 April 1949. He described the site as a shell mound containing shells of scallops and cockles. By the disintegrated condition of the ' shell, Briggs felt that the site was very old. He reported that the depth of the hidden material was at least four feet. Although the presence of artifacts was noted, no description of them was provided. CA-LAn-49: J. Briggs also recorded this site on 26 April 1949. This site was reportedly located at the bottom of a bluff. IBriggs described it as a shell mound containing scallop, cockle, oyster, and some sea snail shells. Briggs noted that the deposit 13 7 !I I has a height of 8 feet and a depth of 6 feet. The site has total depth of 14 feet. I CA-LAn-186: This site was recorded by Hafner, Smith and McKinney ' in October 1965. They described the site as, "Scattered shell bits, site of 'Old Landing', later used as a country club, and still later Castaways, operated by Don Dickerman and Jolly Coburn." The identified shells were clam, pecten and turritellas. The artifacts were described as chert flakes, ' quartz flakes and a broken knife. They further stated that the site was almost completely destroyed. CA-Ora-187: Hafner, Smith and McKinney recorded this site in October of 1965. They describe it as a shell midden composed of the shells of: cockle, clam, pecten, bean clam, lady slipper oyster, and olivella. The artifacts observed were a mano fragment, milling stone, quartz scraper, one projectile point, broken stone bits, and a few quartz flaked. They remarked that the site appears to have been large and extensive, covering the surface of the bluff for at least 1000 feet. The report indicates that the site was destroyed by grading. They further suggest that this may actually be CA-Ora-48 as recorded by Briggs. The records at the ASCULA, however, have this site ' plotted in a location different from that of CA-Ora-48. In addition to the sites described above, at least 30 other archaeological sites are known to exist within a 1.5 kilometer radius of the Castaways Marina project. No attempt to list and describe all of these sites will be undertaken in this report. Their mention here is used to emphasize the archaeological sensitivity of the subject parcel and the surrounding area. .1 14 J 1 I However, one of these sites, CA-Ora-64 is of a high enough significance to warrant mention. CA-Ora-64: "... Is a multicomponent habitation site consisting of two components of the Milling Stone and possibly an earlier component (of the San Dieguito Tradition or a transitional period - San Dieguito Tradition/Milling Stone Horizon)" (Drover et. al. 1983, p. 68). The data recovered from the excavations at CA-Ora- 64 allowed for the refining of a local chronological framework. This in turn allowed for the placement of early post -Pleistocene 1 or Holocene cultural traditions into a definite temporal context. Equally important, investigations at CA-Ora-64 aided in the understanding of the settlement and subsistence strategies of the peoples of the Early Milling Stone Traditions. Information gained from this site can be used not only for the interpretation ' of data from other Early Milling Stone sites occurring on the coast, but can also be applied to our understanding of these same ' site types which are located further inland. In May of 1975 Martin Dean Rosen submitted an Addendum regarding the proposed replacement of the Upper Newport Bay Bridge on the Pacific Coast Highway. This Addendum and a preceding report on the same subject by James R. Gordon, indicate that the site of the original landing in Upper Newport Bay is gone and that I therefore, there would be no adverse impact presented by the construction of a new bridge. ' Further mention was made of the "Old Landing" in a report in 1981 by Larry Seeman and Associates, Inc. This landing site is r 15 r identified as State Historic Landmark #198 and Orange County Historic Landmark #40. The site was reported as destroyed. FIELD RECONNAISSANCE The surface of the Castaways Marina property was examined by the author on 26 July 1989 for evidence of cultural deposition. All of the study area was available for examination. The surface was walked over using a traditional transect method with transects spaced at approximately 20 meters. Disturbance of the study area ranged from quite pronounced to minimal. The project parcel appears to have been graded and flattened. The entire surface of this area is covered with gravel and other imported materials. A concrete seawall has been constructed along the waters edge. Subsurface disturbance is in the form of a fire hydrant and a drainage pipe. This drainage pipe appears to transect the property from Dover Drive to the bay along the bottom edge of the bluff. The contents of this pipe empty directly into the bay. No evidence of the "Old Landing" could be located in this area. The disturbance observed on the disposal site was much less profound. The surface of this area showed signs of discing and/or plowing. Along the eastern edge of the parcel, in about the center, is a stand of Eucalyptus trees. All along the edge of the bluff are paths beaten from pedestrian and bicycle traffic. The bicycle enthusiasts have built small hills and dips to enhance the challenge of the "course". Also found on the northeast corner of the property are the remains of what appears to be dumped dirt. The generally eroded appearance of the piles coupled with the extent of the vegetation growth upon them, suggests that they have been in place for some time. A local resident who has lived in the area since 1965 claims that he 16 I 1 remembers these piles always being there. The material which ' comprises these piles seems to be the same as the surrounding soil. They may be the result of the construction of the housing development which exists immediately to the north of the study ' area. Other deposits of waste material appear near Dover Drive, adjacent to the Lutheran Church property. These piles consists ' of material obviously different from the surrounding soil and of a much more recent origin. I I r 1 1 [1 11 J I LI Located in the Northwest corner of the property are several granitic boulders surrounded by coniferous trees. The above mentioned informant claims that the boulders were brought in and the trees planted as a result of the housing development to the north. No significant cultural deposits other than those already known to exist on the property were encountered during this project. What follows is a description of these pre-existing deposits as observed by the author. CA-Ora-48: This site is located as plotted by Briggs. Although described as otherwise, it still appears to be relatively intact. A culvert cutting into the site has eroded some of the midden into the bay. Examination of the surrounding area revealed that the deposit of shell covered quite an extensive area. The shell extends in a band to 50 meters wide, running diagonally from the northern boundary of the property to a point just past the southwestern side of the Lutheran Church property. Observed in this midden band were mytilus, pecten, olivella, chione, ostrea, 17 11 marine snail and turritella shells. The shell concentration within this band varies greatly. In fact, several discreet midden concentrations are evident. The outline of several rectangular pits was observed within the northeast corner of the site. One of them measured approximately 60 cm. by 120 cm. Since no excavation report is on file at the ASUCLA it is believed that they are the result of unauthorized and illegal digging. Upon examination of the bank directly below the northeast corner of the site and about 1.5 meters above the high tide line, a midden-bearing stratum was observed. The deposit was about 70cm. thick and contained various shell species. Whether this deposit represents an undisturbed cultural deposit or is the result of erosional deposition from the top of the bluff, could not be determined. CA-Ora-49: This site, located at the high tide line, was reported to be in immediate danger of destruction. When comparisons are made between the present deposit and its past description, it becomes apparent that much of the site has been destroyed. The midden is situated on a bedrock outcrop, extends vertically for at least one meter, and is covered by about one half meter of erosional material. Its lateral extent could not be determined. Three distinct strata of charcoal separated by several layers of shell are present. Several of these shell horizons are quite concentrated. Thermally affected rock is evident in the charcoal bearing strata. 18 I I C] I I I I r I r I I I I Located just up the slope from Ca-Ora-49 about two meters from the top of the bluff is an area in which two prehistoric flakes were seen. One was chert, the other was quartz. CA-Ora-186: This site is also correctly plotted on the reference maps at the ASUCLA. It appears to be a multicomponent site consisting of both prehistoric and historic components. Evidence of prehistoric activity is still present on the surface. The surface expression consists of midden material much like that found elsewhere in the study area. The midden was observed eroding down the bluff both towards the bay and to the project parcel. No prehistoric artifacts were observed here. The historic component consists of at least two distinct occupational uses. The first, was as the "Old Landing". No discernible trace of it is left on the surface. The second use, as the Orange County Country Club and Castaways restaurant, is still evident. Chunks of concrete foundation and other pieces of masonry are strewn about. Much of the area is covered by asphalt. In the center of the area is a large pit containing building material and broken glass. The origin of this pit could not be determined. Fragments of sun -colored amethyst glass and shards of porcelain are scattered about (amethyst glass is generally indicative of historical sites at least seventy five years old). Mixed in with this is material of an obviously more recent origin. The surrounding soil is quite dark, containing ash and small pieces of charcoal. CA-Ora-187: Although midden material was observed in the general vicinity of where this site is reported to be, no distinct site was encountered. The description of the site as recorded, places its location in the same area as CA-Ora-48. In their report the W 1 I I recorders noted that they felt this bite may be the same as CA- Ora-48. These three facts lead to the conclusion that sites CA- ' Ora-187 and CA-Ora-48 are indeed one and the same. Just downslope from the edge of the bluff, on the bay side, distributed the length of the property, are many pieces of sun- ' colored amethyst glass. A large piece of farming equipment is located on the eastern side ' of the center of the property. Its exact function was not ascertained but was probably used for cultivation or harvesting. DISCUSSION , The archaeological materials present within the Castaways Marina study area can be classified in two ways, historic and prehistoric. The.historic sites can be further divided into two categories: one which relates to the "Old Landing" and another which is related to the Country Club and its later uses. The prehistoric sites could, conceivably, also be divided into categories. Due to the lack of culturally or temporarily sensitive artifacts, however, any attempt at further categorization at this time would be futile. The project parcel has been the scene of repeated historical use since at least 1863. Development of the area has ranged from subtle to'profound. After reviewing vintage photographs of the area it becomes apparent that much of the development has been depositional in nature. The outcome of this type of development could allow for the preservation of some significant data. It is , uncertain if this has occurred. Subsurface testing would answer this question. 20 1 n r I I ' Archaeological site CA-Ora-186 appears to be quite complicated. Being a multicomponent site, it consists of a prehistoric and at ' least one but probably two historic components. It is not known how profoundly the area was disturbed by the building of the country.club. However, the.remains of the country club itself ' warrant further investigation. The addition of a prehistoric component and a possible "Old Landing" historic component, make this a truly unique site. This site may have the potential to add significantly to our knowledge and understanding of the 1 historical uses of Upper Newport Bay. It is only after subsurface testing that the true significance of this site will be known. Archaeological site CA-Ora-49 is and has, for at least the last 50 years, been undergoing a process of continual destruction. The causes of this destruction are the natural forces which occur in Upper Newport Bay. Being at the high tide line, it is subjected to erosion on a daily basis. It is actually surprising that there is anything left of the site at all. It was noted earlier that this site is comprised of a layering of cultural deposits separated by clear and distinct strata of charcoal. If ' artifacts are present within this deposit, the associated charcoal could allow technical dating of them. Conceivably, this could aid in the recognition of diagnostically time sensitive artifacts. The nature of CA-Ora-48 is unknown at this time. The surface expression of this site covers a large area. Whether the ' subsurface component displays this same characteristic remains to be seen. This site was recorded to have a depth of 4 feet. If ' this proves to be the case, there is a chance that it could be as 21 I E significant as CA-Ora-64 (see page 15 for a description of that site). The lack of artifacts on the surface is probably a result ' of intense unauthorized collecting. Archaeological site CA-Ora-187 probably does not exist as a distinct entity. Either this site is actually CA-Ora-48 proper, or it is at least the southern extension of it. ' The occurrence of sun -colored amethyst glass eroding down the slope of the bluff into the bay has no real significance. It is useful, though, as indication that the entire area along the bluff was being used at least 75 years ago. The piece of farming equipment noted near the center of the property has no archaeological significance. CONCLUSIONS r 1. No new archaeological deposits were detected during the current study. However, some of the recorded sites are larger and more complex than previously thought. , 2. Three previously known sites exist within the study area. ' A. CA-Ora-186 is a multicomponent site comprised of one prehistoric and at ' least one but probably two historic components. The first historic component, which exhibits no surface expression but is presumed to exist, relates to the "Old Landing". The second.component r 22 . r I C I II I J 1 1 I 1 3. 4. 5. 6. definitely relates to the Orange County Country Club/Castaways. B. CA-Ora-49 is a prehistoric site -of undetermined significance. It does exhibit stratagraphic integrity. CA-Ora-49 is currently being destroyed by natural forces taking place in Upper Newport Bay. C. CA-Ora-48 is an apparently extensive prehistoric site of undetermined significance. Evidence suggests that unauthorized and illegal collecting has taken place,at this site. Sun -colored amethyst glass is presently eroding down the bluff of the subject parcel. No great significance can be assigned to it. A piece of farming equipment of an undetermined function exists on the property. No archaeological significance can be assigned to it. Buried historic material may exist in the project parcel. This material, if it exists, probably relates to the "Old Landing". The numerous archaeological sites known to exist in the vicinity indicates that the Castaways Marina study area lies within an area of great archaeological sensitivity. 23 iJ I RECOMMENDATIONS 1.

Bissell 9 May 1990 ' MANAGEMENT SUMMARY A portion of archaeological site CA-Ora-48 was explored. ' through surface examination, posthole excavation and excavation of one controlled unit. The work was undertaken in that part of ' the site which will be impacted by a proposed road. CA-Ora-48 was found to be a well developed shell midden ' containing very few artifacts. The midden averages about 30 to 40 centimeters depth in the studied portion of the site. ' Any ground disturbance necessary to construct the proposed road should be observed by an archaeologist prepared to document and recover any significant material which may appear. 1 1 1 t INTRODUCTION ' During early August 1989 employees of RMW Paleo Associates completed a cultural resources reconnaissance of property known ' as the Castaways Marina, Newport Beach, Orange County, California. One of the archaeological sites discussed in that report (Becker 1989) was CA-Ora-48. This deposit was determined to be an extensive shell midden, but no excavation was accomplished, so its exact subsurface extent, content and degree ' of preservation were unknown. Surface remains indicate that the site extends from the bluff top at the eastern extent of the property to. the rear of existing construction extending into the property from the west. See the Site Location Map on the following page. ' Proposed work at the lower (southern) part of the property requires that a road be installed which will cross the western ' part of CA-Ora-48. The proposed approximate routing of this road is also shown on the page 2 Site Location Map. The proposed road ' will impact CA-Ora-48, but the extent of the impact could not be assessed due to the lack of excavation data. The project ' described in this report was designed to determine the impact of the road construction. No grading will be necessary in that portion of the proposed road which crosses CA-Ora-48, but ' clearing and surface preparation wil-1 be required. The current project consisted of a detailed examination of ' the surface, excavation of a series of postholes and excavation of one controlled unit measuring one by one meter in surface ' extent. ' PROJECT DESCRIPTION . The field portion of the project was accomplished by Ken � ,tr`•Lr 1 •, . AMw 23352 MADERO, SUITE J MISSION VIEJO CA 92691 (714) 770-804i {.Z. "1 KILOMETER SITE LOCATION MAP: A portion of the USGS 7.5 minute Newport Eeach quadrangle, 1965. Photorevised 1981. Approximate site locations are marked. D 1 J 1 t Becker, RMW Paleo Associates Field Director and Stuart Evans, RMW Paleo Associates Archaeologist. The author of this report served as Principal Investigator. Mr. Chris Crespin was the project• Native American Monitor. Becker holds a Bachelors degree in Anthropology and Evans holds a Bachelors degree in History. The author holds a Masters degree in Anthropology and is certified by the Society of Professional Archaeologists as a Field Archaeologist. Various shell remains were noted during the surface examination, but no artifacts were seen. The surface shell was not collected. Twenty two post hole excavations were made. These began at the northern extent of the proposed road and proceeded to the south and east along the right of way across CA-Ora-48. Holes were placed in the center of the right of way and at the eastern and western extent of the right of way. The attached map depicts the location of the excavated postholes. Each posthole was approximately 30 centimeters in diameter. Excavation was accomplished using hand operated clamshell digging . equipment. All material was screened through one eighth inch wire mesh. A rough level was maintained by steel tape measure from the lip of the hole as each excavation proceeded. The only artifact recovered during the posthole excavation was a brick fragment encountered in one of the southernmost holes. However, shell was recovered in sufficient quantities to permit definition of the studied portion of the site. Table 1 on the following page summarizes the distribution of midden shell. Table 1 shows that the site boundaries are fairly well defined in the area to be impacted by the road. The project map contains the site boundary as determined by the post hole excavation. One excavation unit was placed within the densest concentration of midden shell. This unit was one by one meter in surface extent and was excavated in arbitrary levels of 10 centimeters. All material was screened through 1/8 inch wire 3 1 TABLE is Shell Distribution in Posthole Excavations Hole Number Range of Shell Depth Shell Quantity IA Surface Very light 1B None 1C None 2A None 2B None 2C Surface Very light 3A Surface to 85 cm Moderate 3B Surface to 60 cm Moderate 3C Surface to 60 cm Moderate 4A Surface to 80 cm Heavy 4B Surface to 80 cm Heavy 4C Surface to 70 cm Heavy 5A Surface to 80 cm Very Heavy 5B Surface to 60 cm Moderate 5C Surface to 60 cm Moderate 6A Surface to 50 cm Moderate 6B Surface to 30 cm Light 6C Surface to 40 cm Moderate 7A None 7B None 7C Surface to 50 cm Very light 4 PI 1 J' II iL I� mesh. No artifacts were encountered in the excavation, but quantities of shell were recovered. The test unit also revealed that the shell midden is easily differentiated from the underlying soil, which is a distinctly lighter color and contains only very few shell fragments. In the area where the excavation was placed the shell midden varied from about 15 centimeters to as much as 35 centimeters depth. The change in soils can be distinctly seen in the photograph which appears on the following page. CONCLUSIONS 1. CA-Ora-48 is a well developed shell midden. Artifacts are rare in the deposit. 2. The deposit at CA-Ora-48 begins at the surface and is dense to a depth averaging 30 to 40 centimeters in the central part of the studied portion of the site. 3. The proposed road will impact a portion of CA-Ora-48. Any scraping to remove vegetation or scarification to prepare the road surface will disturb the archaeological deposit. 1. An archaeologist should observe all ground disturbing activity within the site limits as depicted on the project map accompanying this report. 2. The archaeologist must be prepared to fully document and recover archaeological data from any significant material which appears. Such recovery work may necessitate some delays in grading if complex deposits are encountered. 3. All work should be described in written reports which receive sufficient distribution to insure their availability to future researchers. 4. All material collected during the project should be donated to a local institution which has the proper facilities for curation, display and use by interested scholars and the general public. 3 ^�!-�, r Y.� - � \. �t.w..--Ili � �/ ^ ;I - I - A ( ''t `� i� � ��l7, �o,Jr�yy✓,!

I have briefly summarized our information for your convenience. . a• L.tnr: Site CA-Ora-48 was first recorded by J. Briggs in 1949 as a 50x200 foot shell midden which extended from the bluff edge westward and had an estimated .Iw: if«arr •,,; •( „•; •,,,, depth of four feet. In 1965, the Pacific Coast Archaeological Society revisit- ,( ..•..: ing the Castaways noted the site was almost completely destroyed. They re- corded the historic ("Old Landing") site (CA Ora-186) and rerecorded CA Ora- 48 as CA Ora-187.. By this time, shell materials had been spread across a 320x290 foot area. C 1 J i 1 In 1972, Archaeological Research Incorporated (ARI) investigated the site while preparing an environmental evaluation for Reynolds and Associates. They excavated 14 backhoe trenches at various points across the Castaways project area. They found the deposits highly disturbed. Mr. Roger Desautels, the Principal Investigator, initiated additional research to solve the problem of the large amounts of shell scattered across the property, well beyond the CA-Ora48 site boundaries described by either Briggs or the Society.

The exact amount of material deposited is unknown", In 1975, the City of Newport, contracted with Wester Services to evaluate the Draft EIR prepared in 1972. At that time Wester noted the confused site history and recommended that the resources be further evaluated prior to grading to comply with City guidelines, In 1981, Ronald Douglas of Archaeological Planning Cooperative (now ISA Associates, Inc) was employed to undertake a field reconnaissance. Mr. Douglas noted: "previous land disturbance on the subject property has caused serious impacts to potentially significant resources. Impacts to archaeological resources resulting from road construction, stockpiling of soils and construction debris, soil compaction, erosion, and commercial devel- opment have almost totally erased any evidence of former archaeolog- ical sites. The results of over 20 years of disturbance on the sub- ject property have displaced fragments of archaeological shell- fish remains, fire -cracked rock, and artifacts, and in some places mixed these remains with recent historic debris (i.e., ssphalt, glass, wood, etc.) (1981:14). Mr. Douglas recommended that, because the Site is disturbed, the appro. priate mitigation measure was to retain a qualified archaeologist to monitor during any grading activities. ISA staff has concerns about potentially intact midden exposed at the bluff edge, and has recommended further studies be conducted on these resources and the historic Orange County Country Club (the "Old Landing" or "Cast- aways") itself. however, we concur with Mr. Douglas' statements for much of the Castaways. Both his and Mr. BLsseIW recommendations appear appro- priate for the area involved and nature of your projeces impacts. I hope this brief archival summary assists you with your future work.

GOVEAN 3 AUGUST 1989 I INTRODUCTION This report presents the results of RMW's Paleo Associates' paleontologic resource assessment of the Castaways Marina Project. The project parcel is approximately 4 acres in size with an adjacent dredge material disposal site of approximately 50 acres. The study site is located northeast of the Pacific Coast Highway and Dover Street intersection and borders Newport Lagoon, Orange County, California (Figure 1). The proposed ' dredge fill site lies immediately to the north of the Castaways Marina Project area (Figure 1). A search was made of the locality records of the Los Angeles County Museum of Natural History and the Orange County Natural History Foundation. .Pertinent geological/paleontological literature was reviewed. A walkover survey of the project and borrow site was conducted on.July 26, 1989 by Dr. Frances Govean. IFIELD SURVEY 1 The Castaways Marina Project site has been previously developed. Trees, bushes and soil, as well as imported rock pebbles, cover ' the surface. A cliff face approximately 25' high at the north boundary of the Castaways property contiguous with the proposed I dredge fill site, is the only major natural rock exposure. The proposed dredge fill site is covered with grasses and trees as well as some asphalt road remnants. Natural rock exposures were ' observed in erosional gullies leading down the cliff face into the upper Newport Lagoon. The cliff faces are rock strata ' covered in some areas by a muddy rind formed by material washing from the bluff top.

A thick recent soil and Pleistocene ' terrace deposits are present stratigraphically above the Capistrano and Monterey Formations on the proposed dredge fill site. At the northern site boundary the Capistrano Formation is a series of light greenish tan and light greenish grey thinly bedded mudstones that are fractured and infiltrated by the mineral gypsum. During the middle Miocene Epoch (approximately 9 to 15 million years Before Present) these Monterey and Capistrano sediments were deposited in a deep ocean basin. The Capistrano and Monterey Formations have a history of producing abundant and 1 scientifically significant fossils throughout their areal extent in southern California. Marine mammals, including extinct whales, walruses, sea lions, seals and dolphins, as well as clams, wood and leaves, boney fish, shark remains, marine microplankton and trace fossils (animal tracks, trails and burrows) have been collected from these units. Along the cliff face of the proposed dredge fill disposal site the Orange County ' Natural History Foundation (OCNHF) has a recorded fossil fish and whale bone locality (Figure 2; client confidential). The Los Angeles County Museum of Natural History has vertebrate ' localities recorded across the bay in the Monterey Formation. Fossil wood was collected from the Monterey Formation during ' excavations for the Fashion Island complex. No vertebrate localities are recorded on the Castaways Marina Project itself. Only microfossils, single celled animal members of the marine plankton, were observed on the site. On the proposed dredge material disposal site an eight to ten foot thick soil horizon and Pleistocene marine terrace deposits 3 I .<' aM 04. � J t d ,. `� `:a " .a�� `�}li .:✓' .h Na • Park / ,• s W , .. •� • 1` .IF,,.('`SS'..?jj ,,a�� ' 4 Mdp Pr''.�y e. � • .L r \, s �� +'Ja ,� _ •�i:r� a• r �ar.n. lob � .�I/ �: % � g �N� t •Par ! r o t � n %'s''`J .`^ N � '• [ s r J/ '� •\ li /' 'J'a It im ,\ \�e0 n .:•� }�tt,�•�t14 ��� �,..• ^a� I '�; � •PR ' 1. 1i' .. {5,, „•,_ ....`.3'U:,`' tip' (�` i •.y�`���^ yj�i ��d'�'} . .a;"'' _,4i.;;::{rt..y�„ ii�1''�rf'�,�¢�:'��:.t1� \�f y � 'te ';f' P"'�r"/}'� •R' it ?,�` its, t •rY �, ! i. i;;�' r— ' r 1 � , d. r ♦♦'i� �� �:,J �•SM HJ•HK,.i� iR •.

Marine shells, predominently Chione, Ostrea, and Pecten, were observed. These remains were interpreted as archaeological midden material, not paleontological remains (Becker, 1989). Some smaller clams and snails could be paleontological material of Pleistocene (10,000 to 120,000 years) age. Pleistocene terrace materials are known to contain the remains of "Ice Age" animals such as elephants, horses, camels, tapirs, deer, extinct bison, reptiles, amphibians and birds. Whale, dolphin, invertebrate, fish and shark remains have also been encountered in equivalent age deposits. On Upper Newport Bay mammal and bird fossils have been recovered. The project site itself has artificial materials, such as pebbles, on the surface and hasrbeen graded. Only recent mussel (Mytilus) fragments and transported midden shell was observed. The Monterey Formation and Capistrano Formations have a HIGH paleontologic sensitivity. Any grading or trenching activities in this unit have a very good likelihood of exposing significant fossil material. Pleistocene terrace materials also are rated a HIGH paleontologic sensitivity because of their past history of yielding fossil remains. Development work that exposes the Capistrano or Monterey Formations and any marine terrace deposits could expose fossil remains. By the same token these excavation activities would destroy them. To reduce adverse impacts on any paleontological resources to an acceptable level the following mitigation measures are recommended. These strategies have been used widely throughout southern California to preserve scientifically significant non-renewable paleontological resources for future study while allowing the completion of development work in a timely manner. 5 I MITIGATION MEASURES I 1. A qualified paleontologist shall be retained to monitor, and if necessary salvage, during excavations of the Monterey and Capistrano Formations and Pleistocene marine terrace ' deposits. 2. This paleontologist shall be empowered to temporarily direct or divert equipment to allow for the evaluation and salvage of fossils. 3. All fossils collected, including contextual stratigraphic data,- should be donated to an institution with an educational and/or research interest in the materials, such as the Orange County Natural History Foundation. , If you have any questions or if we can be of additional service, do not hesitate to contact us.

S Alternative Access ...................................................... 7 Conclusion........................................................... 11 Appendix J IJ r', L I I I PROJECT DESCRIPTION The proposed Castaways Marina site consists of land and open -water areas totaling approximately 4.0 acres. The 2.5 acre land portion is bordered on the east by the Newport backbay, on the west by Dover Drive, on the south by Coast Highway, and on the north by a 60-foot natural and man-made bluff. The marina will consist of floating and pile supported facilities; no hotels, restaurants or snack facilities are part of the project. Figure 1 illustrates the project site, and Figure 2 illustrates the proposed site plan. Access from land to the proposed marina will be from Dover Drive via Coast Highway. An existing raised median along Dover will restrict access to the project parking lot to right turns in and out. The marina will consist of 125 slips of various sizes. Parking will be provided for 108 vehicles at the east and north sides of the basin. An alternative access plan has been developed whereby a new roadway would be constructed parallel to Dover Drive from the site to the intersection with Cliff Drive. This new access roadway would become the fourth leg of this existing Tee -intersection. Both access alternatives are examined Coast Highway is a regional east -west arterial through the City of Newport Beach. North - south regional access to the study area is from Newport Boulevard (SR-55), which connects to several freeways to the north providing access to Orange County and beyond South of Coast Highway, Newport Boulevard enters the Balboa area where the highway terminates at Balboa Boulevard. TRIP GENERATION AND DISTRIBUTION Appropriate trip generation rates for the proposed project were obtained from two traffic counts for similar marinas within the City of Newport Beach. An average inbound rate of .06 trips/slip and an outbound rate of .04 trips/slip for a total of .10 trips/slip were calculated for the peak one hour AM period. For the peak one hour PM period, the average rates were calculated to be .08 trips/slip inbound and .08 trips/slip outbound, for a total of .16 trips/slip. These rates and resulting project trip generation are summarized in Table 1. As this summary indicates, the proposed project will generate 13 trips in the AM peak hour Castaways Marino 1P0 Analysis I Austin -Foust Associates. Inc.

Inc. and 20 trips in the PM peak hour. The trip generation was factored to obtain a peak 2.5 hour volume for the AM and PM peak periods. The peak 2.5 hour volumes were based on an estimated factor of 2.0 to account for the extension of the usual one -hour peak period. ' Distribution of project generated traffic was derived from observed travel patterns in the ' vicinity of the project site as well as from locations and levels of development in relation to the location of the proposed project. The general trip distribution is illustrated in Figure 3. An ' estimated 45 percent of project traffic is assumed to travel north along Newport Boulevard to the Newport Freeway (SR-55) and out of the study area. Along Coast Highway, 20 percent of project ' traffic is assumed to travel west out of the study area, and 25 percent is expected to travel east out of the study area. The remaining 10 percent is assumed to travel out of the study area, with 5 percent of project traffic traveling north along Dover Drive, and 5 percent traveling south along ' Newport Boulevard. Since project traffic will be limited to right -turns only into and out of the project site, outbound project traffic oriented toward Coast Highway will turn right out of the project and make a U-turn at Cliff Drive before travelling south to Coast Highway. Similarly, inbound project traffic from north on Dover will be required to travel to Coast Highway td turn around and access the ' project from northbound on Dover. Since U-turns are prohibited southbound at Dover and Coast Highway, this traffic will make a right -turn onto westbound Coast Highway, make a U-turn along ' Coast Highway, and turn left onto Dover before entering the project site. These movements are reflected in the one percent analysis calculations. ' TRAFFIC IMPACTS The City of Newport Beach identified five intersections for analysis to determine the impact ' of the proposed development. These intersections are: Coast Hwy./Balboa Blvd. -Superior Ave. Coast Hwy./Riverside Ave. Coast Hwy./Tustin Ave. Coast Hwy./Dover Dr: Bayshore Dr. ' Coast Hwy.Bayside Dr. ' Castaways Marino WO Analysis 5 Austin -Foust Associate. Ina A Figure 3 TRIP DISTRIBUTION � m 'm � m m m m M� m m m i� m M M m I� I, J II L_J The 1990 peak 515 hour volumes were provided for each intersection by the City staff. Since the project is expected to be completed by 1993, the ambient growth rate of 1 percent per year was added to all volumes along Coast Highway east of Newport Boulevard. A factor of 2.5 percent per year was added to all volumes along Coast Highway west of Newport Boulevard. The peak 2.5 hour volumes of all approved projects, also provided by the City of Newport Beach, were added to the peak 2.5 hour volumes. The resulting volumes represent the projected peak 2.5 hour volumes prior to the addition of project traffic. A list of approved projects is given in Table 2. One percent of the projected peak 2.5 hour volumes of each approach of each intersection was compared with the peak 2 5 hour distributed volumes from the proposed project. A summary of this comparison is shown in Table 3. If one percent of the 1993 peak 2.5 hour volumes of each approach were larger than the peak 2.5 hour project volumes, no further analyses were required. If project peak 2.5 hour volumes were higher than one percent of the projected peak 2.5 hour volumes on any approach of any intersection, the intersection was analyzed using the Intersection Capacity Utilization (ICU) method. Comparison of the one percent of the peak 2.5 hour volumes with the project peak 2.5 hour volumes resulted in each intersection analyzed passing the one percent analysis and requiring no further analysis. The one percent analysis sheets are included in the appendix ALTERNATIVE ACCESS An alternative access plan has been developed which would provide access to the project at Cliff Drive and Dover. This plan would allow left -turns into and out of the project site at the currently unsignalized intersection. A project access road would become the fourth leg of this intersection with a new signal possibly constructed. The general project distribution will remain the same as for the proposed project; although inbound project traffic from north on Dover and outbound traffic toward Coast Highway will not Castaways Marino TPO Analysis 7 Ausun•Fowt Associates, Ina Table 2 APPROVED PROJECTS SUMMARY Hushes Aircraft #1 Far West Savings and Lout Aemauttonic Fad Banc Bay Office Be* Engineering Cat Canadian Bank Civic Plm Corporate Pim Koll Center Newport MacArthur Court Orchard O@ce Pacific Mutual Plm 3701 Bitch Office Newport Place Bank of Newport Bayside Square Sea Wand Beywocd Apartments Harbor Point Homes Roger's Gudens Se view Lutheran Plan Rudy Bum Quail Business Center 441 Newport Bhd- Cart Business Center Ras Mo0ard Hushes Aircraft #2 Supesrded Flagship Canyon io pital Big Canyon Fun Zone Marriott Hotel St. Andrews Church Allred Coodas Masan Development Four Sessom Hold UW Ath Club TPP 4 Emksy Bb* 400 Medial Amendment N1 MacArthur Court Amendment N2 Ford Arm Calvet Granville!

As this table shows, the alternative access plan passes the one percent analysis at each intersection and requires no further analysis. The one percent analysis sheets are included in the 1 appendix. 1 CONCLUSIONS 1 The proposed Castaways Marina project would generate 26 trips during the AM peak 2.5 hour period and 40 trips during the PM peak 2.5 hour period. Five intersections were checked to 1 determine the marginal impact of project traffic on the street system. All five intersections passed the one percent analysis; therefore, the proposed project has no marginal impact on the study 1 intersections. 1 An alternative access plan was also analyzed in which the project entrance is opposite Cliff Drive thus allowing left -turns into and out of the project site. The alternative access plan also passed the one percent analysis at all five intersection and has no marginal impact on the study intersections. 1 1 i 1 1 1 11 i Castaways Marino TPO Analysis 11 Austin -Foust Assoctates.
