DETERMINATION: (To be completed by the Lead Agency) On the basis of this initial evaluation: QI find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. 7 I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. QI find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. ❑ I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions,QL=gigation ameasust are imposed upon the proposed project, nothing further is requi i Signature Date Don Webb, P.E.

Director of Public Works Ciry of Newport Beach 32 "" Street/Newport Blvd. Street Rehabilitation and 30s' Street/Newport Blvd. Storm Drain Improvements Initial Study/Draft Negative Declaration Page 6 9 0 CJ EVALUATION OF ENVIRONMENTAL IMPACTS A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project - specific factors, as well as general standards (e.g., the project would not expose sensitive receptors to pollutants, based on a project - specific screening analysis). All answers must take account of the whole action involved, including off -site as well as on -site, cumulative as well as project - level, indirect as well as direct, and construction as well as operational impacts. Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact' entries when the determination is made, and EIR is required. "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact' to a "Less Than Significant Impact'. The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analyses ", may be cross - referenced). Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). Earlier analyses are discussed in Section XVII at the end of the checklist. In this case, a brief discussion should identify the following: a) Earlier Analysis Used. Identify and state where they are available for review b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. C) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated ", describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site - specific conditions for the project. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. City of Newport Beach Initial Study/Draft Negative Declaration 32nd Street/Newport Blvd. Street Rehabilitation and 30d' Street/Newport Blvd. Stoma Drain Improvements Page 7 Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project's environmental effects in whatever format is selected. The explanation of each issue should identil[y: a) The significance criteria or threshold, if any used to evaluate each question; and b) The mitigation measure identified, if any, to reduce the impact to less than significant.

City of Newport Beach 32" Street/Newport Blvd. Street Rehabilitation and 30°i Street/Newport Blvd. Storm Drain Improvements Initial Study/Draft Negative Declaration Page 17 ENVIRONMENTAL ANALYSIS This section provides the explanations and supporting analysis for the impact categories and questions contained in the previous checklist, and identifies mitigation measures where applicable. Topics that have no identified impacts, or that have impacts determined to be less than significant without mitigation, will not be discussed in the environmental impact report. L AESTHETICS Would the project: a) Have a substantial adverse effect on a scenic vista? Less Than Significant Impact. The proposed storm drain project would only be visible at the outlet into Newport Bay, since the piping would be installed below grade. The outlet would be constructed in the existing seawall with a tide gate. Although Newport Bay is a notable scenic resource, the outlet would be similar to other outlets that are common around the bay; therefore no substantial impacts to scenic vistas would result. Furthermore, the outlet would,most likely be obscured by docks located adjacent to the bulkhead (see Exhibit 3, Site Photos). No mitigation measures are necessary. During construction, there would be a temporary visual impact to views. These impacts are not considered significant due to their brief duration (i.e., approximately two months). b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? Less Than Significant Impact. See La. above. There are no scenic resources other than Newport Harbor in the immediate vicinity of the project. No mitigation measures are necessary. c) Substantially degrade the existing visual character or quality of the site and its surroundings? Less Than Significant Impact. See discussion under I.a and I.b, above. No mitigation measures are necessary. d) Create a new source of substantial light or glare, which would adversely affect day or nighttime views in the area? No Impact. The proposed storm drain project would not create any new source of light or glare. No mitigation measures are necessary. City of Newport Beach Initial Study/Draft Negative Declaration 32nd Street/Newport Blvd. Street Rehabilitation and 30'" Street/Newport Blvd. Storm Drain Improvements Page 18 E II. AGRICULTURE RESOURCES Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non- agricultural use? No Impact. No agricultural activities occur in the project vicinity. No mitigation measures are necessary. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? No Imnact. The site is not zoned for agriculture and there are no Williamson Act contracts in the vicinity. No mitigation measures are necessary. C) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of farmland, to non- agricultural use? No Impact. The project would not involve any changes that could result in the conversion of farmland. No mitigation measures are necessary. III. AIR QUALITY Where available, the significance criteria established by the applicable air quality management district or air pollution control district may be relied upon to make Ac following determinations. Would the project: a) Conflict with or obstruct implementation of the applicable air quality plan? Less Than Significant Imnact. The project would result in emissions during construction (e.g., dust, construction equipment exhaust). No emissions would be generated after construction is completed. It is anticipated that construction equipment will be limited to one backhoe/loader, one dump truck and one sweeper at the end of each workday. This combination of equipment is estimated to generate substantially less that the significance thresholds identified in the South Coast Air Quality Management District's 1993 CEQA Air Quality Handbook, Table A9 -8 -E. -As a result, the project would not conflict with or obstruct implementation of the air quality plan. Standard contract specifications require that all construction equipment be maintained in proper working order, which would minimize emissions. No additional mitigation is necessary. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Less Than Significant Impact. See Section III.a, above. City of Newport Beach 32nd Street/Newport Blvd. Street Rehabilitation and 3e Street/Newport Blvd. Storm Drain Improvements Initial Study/Draft Negative Declaration Page 19 C) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non- attaiument under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors) ? Less Than Significant Impact. See Section III.a, above. d) Expose sensitive receptors to substantial pollutant concentrations? Less Than Significant Impact. See Section III.a, above. e) Create objectionable odors affecting a substantial number ofpeople? Less Than Significant Impact. Diesel- powered equipment used for excavation and construction could cause odors and emissions that may be offensive to sensitive receptors. There are some residences immediately adjacent to the storm drain alignment, therefore this construction activity would occur in close proximity to sensitive receptors. It is estimated that construction will proceed at an average rate of 100 to 200 feet per day, therefore any given residence would only be impacted for I or 2 days at most. As a result, the issue of odor generation is expected to be less than significant. IV. BIOLOGICAL RESOURCES Would the project: a) Have a substantial adverse effect, either directly or through habitat modifications, off any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? Less Than Significant Impact. Although urban runoff contains contaminants (e.g., oil, heavy metals, pesticides) the construction of a new storm drain and outlet would not have a substantial effect on water quality in Newport Bay since the same runoff from the project area currently flows into the bay through the existing storm drain system. No mitigation measures are necessary. b) Have a substantial adverse effect on airy riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? Less Than Significant Impact. See Section IV.a. above. C) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Less Than Significant Impact. See Section IV.a. above. City of Newport Beach Initial Study/Draft Negative Declaration 32 "d Street/Newport Blvd. Street Rehabilitation and 3e Street/Newport Blvd. Storm Drain Improvements Page 20 Ll • d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Less Than Significant Impact. See Section Ma. above. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? Less Than Significant Impact. See Section IV.a. above. J) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? No Imvact. The site is not included in any Habitat Conservation Plan or NCCP area. No mitigation measures are necessary. V CULTURAL RESOURCES Would the project: a) Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5? No Imvact. There are no historic resources on the site. No mitigation measures are necessary. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to § 15064.5? No Impact. There are no (mown archaeological resources in the vicinity. Balboa Peninsula is composed primarily of sand and dredged material, therefore there is a very low probability that archaeological resources are present. No mitigation measures are necessary. c) Directly or indirectly destroy a unique paleontological resource or site or unique geologicfeature? No Impact. There are no known paleontological resources in the vicinity. Balboa Peninsula is composed primarily of sand and dredged material, therefore there is a very low probability that paleontological resources are present. No mitigation measures are necessary. d) Disturb any human remains, including those interred outside offormal cemeteries? No Impact. Balboa Peninsula is composed primarily of sand and dredged material, therefore there is a very low probability that any human remains could be present. No mitigation measures are necessary. City of Newport Beach 32 "" Street/Newport Blvd. Street Rehabilitation and 30°i Street/Newport Blvd. Storm Drain Improvements Initial Study/Draft Negative Declaration Page 21 VI. GEOLOGYA" SOILS Would the project a) Expose people or structures to potential substantial adverse effects, including the risk ofloss, injury, or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist- Priolo Earthquake Fault Zoning Wrap, issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. No Imnact. There are no known earthquake faults or Alquist - Priolo zones within the vicinity of the project. No mitigation is necessary. ii) Strong seismic ground shaking? No Impact. Although there are no known earthquake faults in the project vicinity, the area is subject to strong seismic ground shaking, as is the case with all of Southern California. This does not present a significant impact, however, since no serious hazards would result if a break were to occur in the storm drain as a result of seismic shaking. No mitigation measures are necessary. iii) Seismic - related ground failure, including liquefaction? No Impact. See item a)ii, above. . iv) Landslides? No Impact. The project area is nearly flat and no significant risk of landslide is present. No mitigation measures are necessary. b) Result in substantial soil erosion or the loss of topsoil? Less Than Significant Impact. The project area is completely urbanized and the project is located entirely within street rights -of -way, therefore no soil erosion or loss of topsoil would - occur during construction operations. No mitigation measures are necessary. C) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off -site landslide, lateral spreading, subsidence, liquefaction or collapse? Less Than Significant Impact. The project area is characterized by sandy soils with the water table at less than 10 feet below the surface. These conditions are conducive to liquefaction during seismic ground shaking. The project would have no effect on these conditions, and would not increase geologic hazards in the area. As noted under VI.a.ii, above, these conditions do not present a significant hazard with respect to the proposed project. No mitigation measures are necessary. City of Newport Beach Initial Study/Draft Negative Declaration r 32"" Street/Newport Blvd. Street Rehabilitation and 30" Street/Newport Blvd. Storm Drain Improvements Page 22 d) Be located on expansive soil, as defined in Table 18 -1 -B of the Uniform Building Code (1994), creating substantial risks to life or property? . Less Than Significant Impact. Expansive soils are generally high in clay content. Soils in the project area are typically sandy, and are not expansive. No mitigation measures are necessary. e) have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? No Impact. The project does not involve the use of septic tanks. All wastewater is presently conveyed off-site via connections to the sanitary sewer system. No mitigation measures are necessary. VII. HAZARDS AND HAZARDOUS MATERIALS Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use or disposal of hazardous materials? No Impact. No use, transport or disposal of hazardous materials is proposed in connection with the project. No mitigation measures are necessary. b) Create a significant hazard to the public or the environment through reasonable foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Less Than Significant Impact. During construction, gasoline- and diesel - powered equipment would be used. In the event of an accident, gasoline or diesel fuel could be spilled. Standard construction contract provisions would require that the contractor follow site maintenance and spill cleanup procedures as described in the Standard Specifications for Public Works Construction (the "Greenbook "). No additional mitigation measures are necessary. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one quarter mile of an existing or proposed school? No Impact. The project would not involve the handling or transport of acutely hazardous materials and would not result in hazardous emissions. The nearest school (Newport Elementary) is located at Balboa Boulevard at 13th Street approximately 1 -1/2 miles from the project area. No mitigation measures are necessary. d) Be located on a site which is included air a list of hazardous materials sites compiled pursuant to Government code Section 65962.5 and as a result, would it create a significant hazard to the public or the environment? No Impact. The project is not located on a listed hazardous materials site. No mitigation measures are necessary. City of Newport Beach Initial Study/Draft Negative Declaration 32°" Street/Newport Blvd. Street Rehabilitation and 3e Street/Newport Blvd. Storm Drain Improvements Page 23 e) For a project located within an airport land use plan or, where such a plait has not been adopted, within two miles or a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? No Impact. The storm drain would have no effect on aircraft- related safety.'i No mitigation measures are necessary. f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? No Impact. There are no private airstrips within the project vicinity. No mitigation measures are necessary. g) Impair implementation of or physically interfere with an adopted emergency response plait or emergency evacuation plan? Less Than SimiScant With Mitigation Incorporated. The proposed storm drain would have no permanent effect on an emergency response or emergency evacuation plan or procedures. Emergency evacuation routes could be affected during construction, however, due to temporary street or lane closures. The following mitigation measure would reduce this impact to a level that is less than significant. Mitigation measure VII -I Traffic Control Plan. Prior to award of a construction contract, a traffic control plan meeting the approval of the City Traffic Engineer shall be prepared. The plan shall specify what measures shall be taken to minimize travel disruptions and safety hazards, including safety ofpedestrians and bicyclists, minimize inconveniences to residents and businesses, minimize the loss ofparking, and ensure adequate emergency access at all times. The traffic control plan shall be incorporated into the contract specifications and shall be enforced by the construction inspector. h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? No Impact. The project site is surrounded by urban development, and no wildland interface exists. No mitigation measures are necessary. City of Newport Beach 32nd Street/Newport Blvd. Street Rehabilitation and 30" Street/Newport Blvd. Storm Drain Improvements Initial Study/Draft Negative Declaration Page 24 • 9 VIII. HYDROLOGYAND WATER QUALITY Would the project: a) Violate any water quality standards or waste discharge requirements? Less Than Significant Impact. The project would involve the discharge of stormwater into Newport Harbor, which would be expected to contain urban pollutants such as pesticides and oil. Since the same runoff from the project area is currently flowing into the harbor, no change in the type or quantity of pollutant runoff would be anticipated. Grading activities could temporarily increase the amount of soil erosion and siltation. Construction will be subject to National Pollutant Discharge Elimination System (NPDES) Best Management Practices, which require that measures be taken to minimize runoff of contaminants and siltation. No additional mitigation measures are necessary. b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge, such that there would be a net deficit in aquifer volume or a lowering ofthe local groundwater table level (e.g., tee production rate of pre- existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? No Impact. Runoff from the area to be served by the proposed storm drain currently flows into Newport Harbor. The project would have no effect on groundwater supplies or recharge. c) Substantially alter the existing drainage pattern of tie site or area, including through • the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site? Less Than Significant Impact. The project would alter the drainage patterns of the area by diverting runoff from the area east of Newport Boulevard in the vicinity of 301' to 32nd Streets into the Rhine Channel. This area currently drains into Rivo Alto Channel, west of Newport Boulevard. Since the area is completely urbanized, no erosion or siltation would result from this change in drainage pattern. During excavation, earth could be spilled onto adjacent streets resulting in siltation if preventative measures are not taken. Required compliance with NPDES Best Management Practices will reduce this construction impact to a level that is less than significant. No mitigation measures are necessary. d) Substantially alter the existing drainage patter: of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner, which would result in flooding onn- or off-site? Less Than Significant Impact. The project: would have no impact on the rate or amount of surface runoff. The capacity of the storm drain system would be enhanced to reduce the risk of flooding. No mitigation measures are necessary. City of Newport Beach Initial Study/Draft Negative Declaration 32nd Street/Newport Blvd. Street Rehabilitation and 30d' Street/Newport Blvd. Storm Drain Improvements Page 25 e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systeuts or provide substantial additional sources of polluti runoff? Less Than SianniScant Impact. The; local drainage pattern would be altered as described in Section VIII.c, above. No increase in runoff would be caused by the project; the capacity of the storm drain system would be enhanced;, however, reducing the risk of flooding. No additional source of polluted runoff would be generated by the project upon completion. During construction, oil, grease or fuel could be spilled from construction equipment onto the street resulting in additional contamination. Required compliance with NPDES Best Management Practices and the Greenbook would reduce this impact to a level that is less than significant. No additional mitigation measures are necessary. n Otherwise substantially degrade water quality? Less Than Significant Impact. The proposed project is not anticipated to generate unusual or substantial amounts of pollutants. Investigation of issues described under Item VIII.a. will address water quality concerns. No mitigation measures are necessary. g) Place housing within a 100 year flood hazard area as »tapped on a federal Flood Hazard Boundary of Flood Insurance Rate Map or other flood hazard delineation »tap No Impact. No housing is proposed in connection with the project. No mitigation measures are necessary. h) Place within a 100 year flood hazard area structures, which would impede or redirect flood flows? No Impact. No structures are proposed that would impede flood flows. The proposed storm drain would improve the efficiency of the draining system. No mitigation measures are necessary. i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or danr? No Impact. The project would not expose additional people or structures to flood hazards. No mitigation measures are necessary. j) Inundation by seiehe, tsunami, or mudflow? No Impact. The site is located in a low -lying area that could be inundated in the event of seiche or tsunami. The project would have no effect on these conditions, however, other than to improve the efficiency of drainage. No mitigation measures are necessary.

LAND USE AND PLANNING Would the project: a) Physically divide an established community? No Imnact. The site is surrounded on all sides by developed land. The project would have no effect on the established community. No mitigation measures are necessary. b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plau, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? No Impact. The proposed project would not conflict with the existing General Plan land use designation or zoning. No mitigation measures are necessary. C) Conflict with any applicable habitat conservation plan or natural community conservation plan? No I_mnact. The site is not located within an NCCP or habitat conservation plan. No mitigation measures are necessary. X. MINERAL RESOURCES 0 Would the project: a) Result in the loss of availability of a known mineral resource that would be a value to the region and the residents of the state? No Impact. The project area is urbanized and no mineral resources would be affected. No mitigation measures are necessary. b) Result in Are loss of availability ofa locally important mineral resource recovery site delineated on a local general plan, specific plan or other laid use plan? No Impact. There are no locally important :mineral resource recovery areas located in the project area. No mitigation measures are necessary. City of Newport Beach Initial Study/Draft Negative Declaration 32" d Street/Newport Blvd. Street Rehabilitation and 3e Street/Newport Blvd. Storm Drain Improvements Page 27 XI NOISE Would the project result its: a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other age I ncies? Less Than Significant With Mitigation Incoroorated. The storm drain project would not result in any long -term noise increase. A short -term noise increase during construction would occur, however. The Newport Beach Municipal Code allows construction only between the hours of 7:00 a.m. and 6:30 p.m. weekdays, and between 8:00 a.m. and 6:00 p.m. Saturdays (NBMC Sec. 10.28.040). The following mitigation measures would further reduce potential noise impacts during construction to a level that is less than significant. Mitigation Measures )U-I Construction Noise. The following requirements shall be incorporated into the project contract specifications and noted on construction plans, and shall be enforced by the City's construction inspector. a. Hours of Construction. No construction shall occur except between the hours of 7:00 a.m. and 6:30 p.m. weekdays unless required to respond to an emergency situation. b. Construction Equipment. All construction equipment, either fixed or mobile, shall be equipped with properly operating and maintained mufflers. 0 C. Staging Areas. Stockpiling and/or vehicle staging areas shall be located as far as practicable from dwellings. b) Exposure ofpersons to orgeneration ofexcessivegroundborne vibration or groundbore noise levels? Less Than Significant With Mitigation Incorporated. A short -term increase in groundbome vibration and noise would be expected to occur during excavation and construction. Limitations on allowable hours of construction would reduce these impacts. Mitigation measure XI -1 would reduce this impact to a level that is less than significant. c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? No I_m_pact. The project would have no long -term noise impacts. No mitigation is necessary. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant With Mitigation Incorporated. See Section XI.a, above. City of Newport Beach Initial Study/Draft Negative Declaration 32nd Street/Newport Blvd. Street Rehabilitation and 30d' Street/Newport Blvd. Storm Drain Improvements page 28 e) For a project located within an airport land use plan or, where such a plan has not been adopted, widen two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? Less Than Significant Impact. The site is located near the flight path from John Wayne Airport; therefore construction workers would be subject to minor noise impacts due to aircraft overflight. These impacts are not considered significant, however, since the area is outside the 65 dB CNEL noise contour and their exposure would be temporary. No mitigation measures are necessary. j) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? No Impact. There are no private airstrips within the vicinity of the site. No mitigation measures are necessary. XII. POPULATION AND HOUSING Would cite project. a) Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? No Impact. The project site is fully developed and the proposal consists of the replacement of an existing storm drain. No increase in development potential would occur as a result from the project. No mitigation measures are necessary. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? No Impact. There is no existing housing that would be displaced by the proposed development No mitigation measures are necessary. c) Displace substantial numbers of people, necessitating tee construction of replacement housing elsewhere? No Impact. No people or existing housing would be displaced by the proposed development. No mitigation measures are necessary. City of Newport Beach 32 itd StreettNewport Blvd. Street Rehabilitation and 30'" StreettNewport Blvd. Storm Drain Improvements Initial Study/Draft Negative Declaration Page 29 XIIL PUBLICSERVICES Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for u e w or physically altered governmental facilities, the construction o %which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of these public services. a) Fire protection? No Impact. The proposed project would have no effect on fire protection. No mitigation measures are necessary. b) Police protection? No Impact. The proposed project would have no effect on police protection. Traffic control during construction will be provided by the contractor in a manner meeting the approval of the City Traffic Engineer (see Mitigation Measure No 7 -1 on page 23). No additional mitigation measures are necessary. C) Schools? No Impact. The proposed project would have no effect on student generation or school operations. No mitigation measures are necessary. d) Parks? No Impact. The proposed project would have no effect on parks or recreation. No mitigation measures are necessary. e) Otis er public facilities? No Impact. The proposed project would have no effect on any other public facilities. No mitigation measures are necessary. XIV. RECREATION a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities, such that substantial physical deterioration of the facility would occur or be accelerated? No Impact. The proposed project would not increase the use of parks or other recreation facilities. No mitigation measures are necessary. b) Does the project include recreational facilities or require lite construction or expansion of recreational facilities, which might have an adverse physical effect on the environment? No Impact. See Section XIV.a, above. City of Newport Beach Initial Study/Draft Negative Declaration 32" Street/Newport Blvd. Street Rehabilitation and 3e Street/Newport Blvd. Storm Drain Improvements Page 10 XV. TRANSPORTATIONITRAFFIC Would the project: a) Cause an increase in traffic, which is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? Less Than Significant Impact. The project would have no effect on long -term traffic levels. A short-term increase in traffic from construction equipment and workers would be expected to occur, however. It is anticipated that 10 -15 workers will be employed on site during construction, generating approximately 2040 trips per day. In addition, an estimated 32 truck trips will be required over the duration of project construction (less than one trip per day on average) to haul excess earth material away from the site. This traffic increase would not be considered significant. Mitigation Measure VII -I (see page 24) would further reduce this impact by requiring the preparation of a traffic control plan prior to commencement of the project. b) Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency for designated roads or highways? Less Than Significant Impact. See Section XV.a, above. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? No Impact. The project would have no effect on air traffic patterns. No mitigation measures are necessary. d) Substantially increase hazards due to a design feature (eg., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Less Than Significant With Mitigation Incorporated. The project could disrupt traffic patterns during construction due to lane closures or traffic diversions. Mitigation Measure VII -1 (see page 24) would reduce this impact to a level that is less than significant. e) Result in inadequate emergency access? Less Than Significant With Mitigation Incorporated. See Section XVA, above. n Result in inadequate parking capacity? Less Than Significant With Mitigation Incorporated. The project would have no effect on long -term parking demand or capacity. Demand for additional parking would be created by construction workers, however. It is estimated that between 10 and 15 workers will be on -site at any given time, requiring a maximum of IS parking spaces. In addition, some on -street or off - street parking may be temporarily unavailable during construction. Mitigation Measure VII -I (see page 24) would reduce this impact to a level that is less than significant. City of Newport Beach Initial Study/Draft Negative Declaration 32nd Street/Newport Blvd. Street Rehabilitation and 30' Street/Newport Blvd. Storm Drain Improvements Page 31 g) Conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)? Less Than Significant With Mitigation Incorporated. The project would have no long- term effect on alternative transportation. Potential disruption of bus travel and bicycle lanes could occur during construction, however. Mitigation Measure 7 -1 (page 24) would reduce this impact to a level that is less than significant. XVI. UTILITIES AND SERVICE SYSTEMS Would the project: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? No Impact. The project would have no effect on wastewater flows or treatment requirements. No mitigation measures are necessary. b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? No Impact. The project would have no effect on wastewater flows or treatment requirements. No mitigation measures are necessary. . C) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? Less Than Significant Impact. The proposed project is the replacement of existing deteriorated storm drains and the installation of a new storm drain along 30" Street and Newport Boulevard. No increase in stormwater flows would result, and no new or expanded drainage facilities beyond those included in this project would be required. No mitigation measures are necessary. d) Have sufficient water supplies available to serve tke project from existing entitlements and resources, or are new or expanded entitlements needed? No Impac t. The project would have no effect on water supply or demand. No mitigation measures are necessary. e) Result in a determination by the wastewater treatment provider, which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? No Impact. See Section XVI.b, above. City of Newport Beach Initial Study/Draft Negative Declaration 32nd Street/Newport Blvd. Street Rehabilitation and 300' Street/Newport Blvd. Storm Drain Improvements Page 32 0 J) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? • Less Than Significant Impact. Constructions of the project may result in the generation of excess earth material that would need to be transported off site. This would not be considered a significant impact due to its temporary nature and limited volume. Excess fill would most likely be used at another construction site. Fill that could not be used would be disposed of at a landfill. Used asphalt would be recycled by the contractor. No mitigation measures are necessary. g) Comply with federal, state, and local statutes and regulations related to solid waste? Less Than Significant With Mitigation Incorporated. The project could generate solid waste during construction. Standard contract specifications requiring the contractor to dispose of waste in accordance with applicable statutes and regulations would reduce this impact to a level that is less than significant. No mitigation measures are necessary. MANDATORYFINDINGS OF SIGNIFICANCE a) Does the project have tee potential to degrade the quality of the environment, substantially reduce the habitat of a fnsh 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 important examples of the major periods of California history or prehistory? Less Than Significant With Mitigation Incorporated. The project has the potential to degrade the quality of the environment, but the mitigation measures recommended would reduce these potential impacts to a level that is less than significant. b) Does the project have impacts that are individually limited, but cumulatively considerable? ( "Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects ofpast projects, the effects of other current projects, and tine effects of probable future projects.) Less Than Significant With Mitigation Incorporated. The project would contribute to short-term cumulative impacts in the areas of air quality, noise and traffic during the two -month construction period. The project's contribution to these cumulative impacts would be substantially reduced by the recommended mitigation measures, however, and the incremental impacts of the project would be so small that they would make only a de minimis contribution to the cumulative impacts caused by other projects. c) Does the project have environmental effects, which will cause substantial adverse effects on human beings, either directy or indirectly? Less Than Significant With Mitigation Incomorated. The recommended mitigation measures would substantially reduce the potential impacts of the project to a level that is less than significant.
