(Leighton) is pleased to present the results of our fault investigation behind the proposed parking area at the Lower Campus at Hoag Hospital (Figure 1). The area of our investigation was limited to the portion of the lower campus below the terrace bluff and west of Hoag Drive. �• P=ose and Scone of Work ' The primary purpose of this study was to determine if a splay of the North Branch of the Newport - Inglewood Fault Zone is present on the property owned by Hoag behind the proposed parking lot. ' If a fault was encountered, we would assess, if possible, the recency of faulting to evaluate the potential for future surface fault rupture at the site. To conduct this study we performed the following tasks: • Reviewed readily available reports on the geology of the area as well as aerial photographs of the site; • Observation of a 1250 foot long cut slope excavated to expose the contact between the Monterey Formation and the overlying Quaternary Ten -ace; • Observation of bedrock exposed in the subdrain trench excavated at the toe of the cut slope; and • Preparation of this report which summarizes our findings, conclusions, and recommendations.

A stoma drain and utility lines for the gas flare are located on the flat portion of the parcel. The natural bluff forming the northern boundary of the study area has been modified on the eastern '.; side of the study area during grading for the adjacent condominiums (located to the north). Grading resulted in addition of about 8 to 12 feet of fill over the natural slope. Minor amounts of fill were also placed at the toe of the bluff, adjacent to the Child Care Center. Grading is proposed for the site to develop a parking lot on the lower terrace, adjacent to Pacific ' Coast Highway. The flat terrace above the bluff will be dedicated to the City of Newport Beach for use as a linear park. IPrevious Fault Studies �• Mapping for the Versailles condominiums, adjacent to the study area on the upper terrace was performed by GeoSoils, Inc. in 1978. For their study GeoSoils mapped the bedrock/terrace contact from Superior Avenue, eastward across the study area. GeoSoils recognized two faults west of station 8+50 but, the faults did not offset Holocene age soils. Guptill and Heath (1981) mapping west of the property at Pacific Coast Highway and Superior Avenue, located the terrace deposits, offset against the Miocene Monterey Formation. Their mapping indicated approximately 3 feet of vertical offset of the bedrock/terrace contact and based on offsite exposure they postulated historic fault displacement. They referred to this fault as the North Branch Splay. During subsequent work, Guptill, Armstrong, and Egli (1989) excavated several trenches across these faults. The trenches and soil units were logged and the relative ages of the soils and geomorphic surfaces. This subsequent study by Guptill, et al (1989) found that although the Pleistocene age terrace deposits had been offset, the faults did not offset the upper part of the late Pleistocene soils. They concluded, based on their recent trenching with a better developed soil profile, that the North Branch Splay was not active. LeRoy Crandall mapped the slope in 1989 and 1991 as part of their work for the master planning ' development of the Lower Campus of the Hospital. In their reports they discuss mapping the bedrock/terrace contact along the slope. They found no offset on the site and concluded there was no active faulting in the study area. lie Of -2 ftJ LE UMMANCAMOCLITO, IMC. 1950076-01 Merrill Wright excavated three trenches on the Lower Campus in 1993. The location of these three trenches is shown on Plate 1 of this report. Wright's trenches exposed several faults and fractures in the Monterey Formation bedrock but the bedrock was overlain by fill and Wright was unable to trace the faults upward to determine if the bedrock/terrace contact was offset. Wright mapped the slopes adjacent to the exploratory trenches and did not find any offset beds in the terrace deposits along the projected trend of the faults or fractures found in the trenches. Wright concluded that the faults and fractures found in the trenches were confined to the Miocene age Monterey Formation. INVESTIGATION METHODS Aerial Photograph Analysis Black and white, vertical aerial photographs were reviewed to evaluate whether abrupt changes in elevation, contrasts in vegetation or soil, or other lineaments of possible fault origin could be discerned across or adjacent to the site. The stereo -paired photographs reviewed were taken between 1928 and 1952, and are listed in Appendix. Subsurface Exploration For the purposes of this study we examined a cut slope approximately 1250 feet long that began adjacent to Pacific Coast Highway. The slope was constructed as part of the proposed parking lot and subdrain system. It began at the western corner of the site, and extended in an easterly direction toward the Child Care Center. The slope was excavated across the regional trend of the NIFZ. The slope exposed bedrock of the Monterey Formation as well as the overlying Quaternary terrace deposits. Two different terraces appear to be present. For our fault investigation we examined the freshly cut slope behind the proposed parking lot adjacent to Pacific Coast Highway. We examined the slope from the centerline of the entry road (Hoag Drive) at the intersection with Pacific Coast Highway, westward until the slope curved southward to Pacific Coast Highway. Geologists from our firm cleaned the slope to remove the soil materials smeared by the excavation equipment, and mapped the geologic units exposed on the slope (Geology Map, Plate 1). For reference, stationing was assigned to the beginning at the western comer of the slope. Along the fresh slope the contact between the Monterey Formation and the overlying Quaternary Terrace Deposits was examined for offsets. The contact was sharp, clearly defined and easily traced across the site. Shears within the bedrock were traced upward to the terrace contact to verify continuity without offset. Fractures in the terrace deposits were traced downward to the contact to verify lateral continuity without offset of the contact. In areas where the terrace/bedrock contact -3- LE/CNTON AND ASSCCMTES)NC. 1950076-01 was covered with fill the bedrock was examined for shears. Where shears were found they were projected or traced upward into the terrace deposits. The terrace deposits were then examined and sand beds or other compositional layering was traced across the projected shear trace to demonstrate lateral continuity without offset. FINDINGS The project area lies along the Newport -Inglewood structural zone in southern California. This zone is a major tectonic boundary in the region and contains the Newport Inglewood fault. A splay of the North Branch of the Newport -Inglewood fault is located adjacent to the Lower Campus on Pacific Coast Highway. Along the freshly cut slope, the contact between the Miocene age Monterey Formation and the Quaternary age terrace deposits was examined for offsets. The contact was sharp, clearly defined and easily traced across the site to the region behind the existing gas flare. Shears within were easily observed and traced up to the terrace contact. The contact itself was readily identified. The contact is a nearly flat, slightly undulating erosional surface. The surface is marked by a one-half to one inch thick, nearly horizontal, light grey clay layer. The clay layer was not observed to be offset by any of the fractures or shears in the bedrock. In areas where this clay layer was indistinct or absent, thin sand beds or stringers parallel to bedding within the terrace deposits were traceable through the terrace. At approximately station 7+50 a sand filled fracture in the Quaternary terrace deposit was mapped. The fracture was approximately four to six inches thick and had apparent offset of beds within the terrace. The fracture was traced upward to where it died out below the soil horizon, consistent with the findings by GeoSoils (1978). The fracture could not be traced to the clay layer at the bedrock/terrace contact and the contact was not offset by the fracture. At station 9+75 the contact was obscured by fill placed during grading for the condominiums on the upper terrace. Vertical slots cut through the fill at 10 foot intervals for backdrain placement allowed intermittent observation of the contact through station 10+50. Visual alignment of the terrace/bedrock contact between these slots indicated no offset of the contact. A trench was excavated at the toe of the slope from station 9+50 to 12+50. This trench revealed bedrock overlain by fill. East of station 11+50 bedding exposed in the trench was not offset by faulting. West of this station numerous fractures and small faults were observed in the trench. These faults and fractures were projected visually to the excavated slope and the slope was checked to determine if the bedrock/terrace contact was offset. In addition, previous mapping by Law/Crandall and GeoSoils were reviewed for the area obscured by fill. In the area where fill presently covers the bedrock/terrace contact, both consultants had mapped the bedrock/terrace contact prior to placement of the fill and found the contact was laterally continuous without offset. Each concluded that there were no active faults on this portion of the site. 1950076-01 CONCLUSIONS AND RECOMMENDATIONS Based on our field mapping, fractures and shears were observed in the Miocene age bedrock, as expected in this tectonic environment. Our mapping of the terrace bedrock contact, indicated no evidence for offset of the contact between stations 0+00 and 9+75. Intermittent observation of the bedrock/terrace contact between stations 9+75 to 10+50 indicated no offset of the contact. Previous mapping by GeoSoils, Inc. in 1978 and by Law/Crandall found no evidence of Holocene faulting between stations 10+50 and 12+50. Based on our observations of the recently cut slope and review of prior mapping along the before fill was placed along the east side of our study area, it is our opinion that although faults are present in the Miocene age bedrock, they do not offset earth materials younger than 11,000 years old. Therefore, the faults are not considered active under the Sate of California Alquist-Priolo act. If you should have any questions regarding this report, please contact us.

ASTM Designation D2922-81 nuclear gauge in -place density tests (equivalent to UBC-70-5) were performed to establish the degree of compaction achieved. The asphaltic paving was to be compacted to at least 95% of the maximum density. The data derived from the performance of the nuclear in -place density tests are included in the Table of Test Results; the approximate locations of the tests are shown on the Geologic Map and Plot Plan. The paving section for the Child Care Center parking lot and drives consisted of a 3-inch-thick section of 1/2-inch aggregate asphalt using AR4000 asphalt cement over a 4-inch-thick section of base. A 31/2-inch-thick section of 1/2-inch aggregate asphalt using AR4000 asphalt cement over an 8'V2-inch-thick section of base was placed in the temporary parking lot over the previous retarding basin area. Existing asphalt and concrete surfaces were cleaned and tack -coated prior to the placement of the asphalt sections. At the time of delivery, the temperature of the asphalt ranged from 2750 to 3100 Fahrenheit. A value of 143 pounds per cubic foot was utilized for the maximum density of the 1/2-inch aggregate asphalt. The asphalt was compacted by 5- to 8-ton, 8- to 10-ton, and 10- to 12-ton dual steel drum rollers. GEOLOGIC CONDITIONS Geologic mapping was performed intermittently during the grading of Increments 1 and 2 -of the Cancer Center site. The geologic conditions exposed as a result of the grading were essentially as anticipated in our geotechnicai report dated September 15, 1987 (LCA AE- 87147). The site is underlain by marine terrace materials composed of interbedded clay, silt, and sand. These materials are typical of the poorly indurated materials that blanket the mesas of the Orange County Coastal Plain. At the western end of the excavation, this deposit was found to be about 19 feet thick. The terrace was horizontally stratified and ' LCA O90038.B Page 8 J increased in thickness to 23 feet near the eastern 1/4 of the building. At this location, the contact with the underlying siltstone dipped off to thicken to greater than 40 feet. This thickening was likewise observed in Trench 3 in the previous investigation. Based upon the exposures in the excavation and the backhoe trench, we believe this to be an unconformable contact with terrace strata lapping onto the older siltstone bedrock. This contact is irregular but continuous across the site and has no clay gouge associated with it. The terrace deposits are underlain by claystone and siltstone of the Miocene age Monterey Formation. These rocks are exposed in the bluffs at the south and west edges of Newport Mesa. The Monterey Formation located adjacent to the site generally strikes N60W to N80E and dips between 20 to 50 degrees to the northeast. Within this excavation, the claystone and siltstone exhibited tight undulatory folding and local shearing. None of these folds or shears deflected the overlying terrace contact. Therefore, these shears and folds are believed to predate the Quaternary terrace deposits. The existing cut slope located to the north of the Child Care Center site ascends at an overall inclination of about 21h:1 (horizontal to vertical). The height of the slope in the area of this proposed construction is on the order of 40 feet. The majority of the existing slope was cut in the mid 1960s, when the site was used as a borrow area for other off -site grading and construction. During recent grading operations for the Child Care Center, about the lower 15 feet of the slope was graded to a 2:1 slope ratio. Based on our observations, the lower 6 to 8 feet of the cut slope exposes the Monterey Formation claystone and siltstone. The Monterey Formation units exposed north of the Child Care Center have been folded into a southeasterly plunging syncline. Beds east of the synclinal axis strike northwest -southeast and dip 16 to 25 degrees southwesterly towards the fold axis. West of the fold axis, the beds strike northwest to west-northwest and dip 2 to 26 degrees towards the north and northeast. LCA O90038.B Page 9 h Based upon the continuity of the terrace/siltstone contact, we found no evidence for faulting within the limits of grading for the subject Hoag Child Care Center project. All final slope surface configurations within the limits of grading were graded to a 2:1 slope ratio in conformance with the grading plans. When planted and maintained, these slopes are expected to be grossly and surficially stable. This final report is limited to the earthwork performed through December 14, 1990, the date of our last observation and/or testing of the soil -related work for the project. Grading for the Hoag Child Care Center development is in conformance with our geologic recommendations presented in our geotechnical investigation report dated April 20, 1990 (LCA O89083.AEB) and is suitable from a geologic standpoint. The grading for the Child Care Center development will not adversely affect the geologic stability of the off -site properties. We find the graded site to be safe from the hazards of landsliding, settlement, and slippage. Based on our observations, we are satisfied that the foundation excavations and subgrades for concrete slabs and walks and for asphaltic paving were prepared in accordance with the project plans and specifications. The fill, backfill, base course and asphaltic paving, at the locations and elevations tested by us, were compacted to at least the specified degree of compaction. The asphaltic paving, where tested, also met the specification requirements. Also, the foundation excavations extended into satisfactory compacted fill or undisturbed natural soils. In our opinion, the geotechnical related work was performed in general compliance with the project plans, specifications, and the City of Newport Beach Municipal Code, and is considered suitable for the intended use.

A value of 143 pounds per cubic foot was utilized for the maximum density. GEOLOGIC CONDITIONS Periodic geologic mapping was performed at various phases of the Increment 1 grading. This' mapping found the conditions to be essen- tially as anticipated. The site is underlain by marine terrace materials composed of interbedded clay, silt, and sand. These materials are typical of the poorly indurated materials that blanket the mesas of the Orange County Coastal Plain. At the western end of the excavation, this deposit was found to be about 19 feet thick. The terrace was horizontally strati- fied and increased in thickness to 23 feet near the eastern 1/4 of the building. At this location, the contact with the underlying siltstone dipped off to thicken to greater than 40 feet. This thickening was likewise observed in trench 3 in the previous investigation. Based upon the exposures in the excavation and the backhoe trench, we believe this to be an unconformable contact with terrace strata lapping onto the older siltstone bedrock. This contact is irregular but continuous across the site and has no clay gouge associated with it. The terrace deposits are underlain by claystone and siltstone of the Miocene age Monterey Formation. These rocks are exposed in the bluffs at the south and west edges of Newport Mesa. The Monterey Formation located adjacent to the site is generally striking N60W to Page 10 N80E and dipping between 20 to 50° to the northeast. Within this excavation, the claystone and siltstone exhibited rapid undulatory folding and local shearing. None of these folds or shears deflected the overlying terrace contact. Therefore, these shears and folds are believed to predate this Quaternary terrace deposit. Based upon the continuity of the terrace/ siltstone contact, we found no evidence for active faulting within the limits of grading. CONCLUSIONS This report is limited to the earthwork performed through January 25, 1989, the date of our last observation and/or testing of the soils related work for Increment 1 of the project development. At the locations and elevations tested by us, the fill, back - fill, base course and asphaltic paving were compacted to at least the specified degree of compaction, and are suitable for the intended use. Also, the shoring as installed should serve as required. In addition, the geological observations revealed no conditions which varied from those anticipated. In providing professional geotechnical observations and testing services associated with the development of the project, we have employed accepted engineering and testing procedures and have made every reasonable effort to ascertain that the soil related work was carried out in general compliance with the project plans and speci- fications, and the City of Newport Beach Municipal Code.

A 3-inch-thick section of asphaltic concrete was placed in the parking areas and a 4-inch-thick section of asphaltic concrete was placed in the roadway and drive areas. Existing asphalt and concrete surfaces were cleaned and tack -coated prior to the placement of the asphalt sections. At the time of delivery, the temperature of the asphalt ranged from 275' to 310' Fahrenheit. Values of 146 and 147 pounds per cubic foot were utilized for the maximum densities of the 3/4-inch aggregate asphalt, and values of 143 and 145 pounds per cubic foot were utilized for the maximum densities of the 1/2-inch aggregate asphalt. The asphalt was compacted by 5- to 8-ton, 8- to 10-ton, and 10- to 12-ton dual steel drum rollers. GEOLOGIC CONDITIONS Geologic mapping was performed intermittently during the grading of Increments 1 and 2. The geologic conditions exposed as a result of the grading were essentially as anticipated in our geotechnical report dated September 15, 1987 (LCA AE-87147). The site is underlain by marine terrace deposits composed of interbedded clay, silt, and sand. These materials are typical of the poorly indurated materials that blanket the mesas of the Orange County Coastal Plain. The terrace deposits vary in thickness between 19 and 40 feet, a condition likewise observed in trench 3 in the previous investigation. Based upon the exposures in the excavation and the backhoe trench, we believe this to be an unconformable contact with terrace strata lapping onto the older siltstone bedrock. This contact is irregular but continuous across the site and has no clay gouge associated with it. The terrace deposits are underlain by claystone and siltstone of the Miocene age Monterey Formation. These rocks are exposed in the bluffs at the south and west edges of Newport Mesa. The Monterey Formation located adjacent to the site generally strikes N60W to N80E and dips between 20 degrees to 50 degrees to the northeast. Within this excavation, the claystone and siltstone exhibited tight undulatory folding and local shearing. None of these folds or shears deformed the overlying terrace contact. Therefore, these shears and folds are believed to predate the Quaternary terrace deposit. + LCA B-88064-B Page 9 c The existing cut slope located to the north of the proposed Hoag Child Care Center ascends at an overall inclination of about 21h:1 (horizontal to vertical). The height of the slope in the area of this proposed construction is on the order of 40 feet. The majority of the existing slope was cut in the mid 1960s, when the site was used as a borrow area for other off -site grading and construction. During recent grading operations for the proposed Hoag Child Care Center, about the lower 10 feet of the slope was graded to a 2:1 slope ratio. Based on our observations, the lower 6 to 8 feet of the cut slope exposes the Monterey Formation claystone and siltstone. The Monterey Formation units exposed north of the proposed Child Care Center have been folded into a southeasterly plunging syncline. Beds east of synclinal axis strike northwest - southeast and dip 16 to 25 degrees southwesterly towards the fold axis. West of the fold axis, the beds strike northwest to west-northwest and dip 2 to 26 degrees towards the north and northeast. Based upon the continuity of the terrace/siltstone contact, we found no evidence for faulting within the limits of grading for the subject Hoag Cancer Center project. All final slope surface configurations within the limits of grading were graded to a 2:1 slope ratio in conformance with the grading plans. When planted and maintained, these slopes are expected to be grossly and surficially stable. CONCLUSIONS This final report is limited to the earthwork performed through October 4, 1990, the date of our last observation and/or testing of the soil -related work for the project. Grading for the Hoag Cancer Center Increment 2 Development is in conformance with our geologic recommendations presented in our geotechnical investigation report dated May 26, 1987 (LCA AE-87147) and is suitable from a geologic standpoint. The grading for the Increment 2 Development will not adversely affect the geologic stability of the off -site % PROJECT NO. \ \ B-88064-B I 1 1 � °04o c°y \J�. oM\N\�� \ \�v; . v °'yil,,co� � °'�'D°���/ DO�i�,yN�, LpNOp�\N GpNo � 2 r I/ IQw � / 6 ►1 \ _ \\� O PARKING 2 03 04 � _ 5_ Ind '� � STRUCTURE , O 9 70 O 2 4 06 •5 07 EN COAST 6 °0 01 �6 8 ot+ �7 11 O �� e�y�' O 8 01 9 O 9 HIGHWAY 10 80 CURRENT INVESTIGATION 1995 / 1701313-0689.0001) 11�y PREVIOUS INVESTIGATION 1993 �Y (2661.30916.0001) / 2 n PREVIOUS INVESTIGATION1989 (089083.AEB) 10 O PREVIOUS INVESTIGATION 1989 REFERENCE: (0890N.AEO) SITE PLAN (DATED 4121195) BY DAVID A.

Thibeault Executive Officer California Regional Water Quality Control Board Santa Ana Region 3737 Main Street, Suite 500 Riverside, CA 92501-3339 Re: Hoag Project #1252.78 Dear Mr. Thibeault: Lower Campus West Parking Lot On May 3, 1996, Hoag Hospital was authorized to discharge groundwater resulting from its Lower Campus parking lot construction project (NPDES No. CAG.998001, enclosed). That project is currently underway and is being monitored in accordance with the requirements of Monitoring and Reporting Program No. 93-49-035. The Master Plan for development at Hoag Hospital was approved by the City of Newport Beach in August of 1992. A final environmental impact report for the Master Plan project was also certified at that time.

A permit has been Issued and we are under construction. The illumination of the structure is very important to Hoag; the structure will be the cornerstone of our front entrance and thousands of'patients will navigate through this building when they use the hospital facilities. We -have spent thousands of dollars designing a lighting system that would meet the city requirements and the hospital special needs. I respectfully request that the city review our general lighting plan and photometric studies for the project; provide written comments or approve the plan as designed before it is cast in concrete. Hoag recently completed the Conference Center parking structure. During the design, Hoag's electrical engineer worked with lighting manufacturers to select the best available fixture that would meet the city requirements; however, during the final Inspection of the project, we were directed by the city to modify the designed lighting scheme to reduce light spilling to the adjacent development. This process Is very subjective. There was no measurable light projecting from our property. A similar amount of light shines from adjacent developments on to hospital property. The light from the city streetlights is significantly brighter space. Hoag was forced to spend thousands of dollars to comply with the request by installing louvers over the lights, which decreased their efficiency. It took weeks to special order the louvers, and the building could not be occupied until they were installed. The result met the city requirements; however, now I receive numerous complaints from our staff and community members who use the center at night because the level is dimly lighted and does not feel safe. We believe that we�have'fourid a better way to light the Interior of the new structure. We studied several methods to conceal the light source and still provide suitable safe and comfortable lighting levels. We ruled out screens or louvers on the outside of the building shell, because they would create a "boxy" structure; Instead, we designed an `open" structure that has been favorably received by city planners and coundlpersons. We ruled out standard Fluorescent fixtures and the contemporary fixtures that were rejected by the City in the Conference Center structure. We studied Indirect lighting and decided to paint the structure ceiling to create a very finished interior and provide a soft light bounce from a "state of the art" up -light fixture. The selected fixture is designed to conceal the light source and minimizes light spillage and glare. In order to avoid the previous fiasco, we requested that Jim Sinasek, City of Newport Beach Code Enforcement, provide an Informal review of a full size lighting mock-up of one bay of this structure. He reviewed the mock up and on July 17, 2000, he replied to Jim Easley, Hoag Project Manager, stating his concern that the ceiling is illuminated with some "hot spots" and Hoag's neighbors may be upset with four levels of Illuminated ceilings shining in their eyes. He declined to provide further comment, because he would notbe able to evaluate the light until the total structure is constructed and illuminated. I am sure you can understand our concern that any objections to the design that are raised after the project is complete, will be very costly to correct. We believe that the design exceeds the mitigation requirements and can be reviewed and approved prior to construction as noted in the measure. If our architects or I can be of help or provide additional Information, please call me. Thank you in advance for your consideration. I look forward to your response.

The measure reads as follows: "To further determine the source of the gas on the Lower Campus site, prior to the issuance of a grading permit on the Lower Campus, Project Sponsor shall collect gas samples from the nearest fire flooding wells and at Newport Beach Townhomes and compare the gas samples to samples taken from the Hoag gas collection wells prior to site grading and construction." The samples from the Newport Townhomes and from the Hoag Hospital Lower Campus gas collection wells have been taken. The fire flood well samples will not be available. The operator, West Newport oil Company, has declined to allow the taking of samples on their leases. Requests for sampling were made twice in late 1992 and again in October 1993. A composite sample of the gas produced at the City.of Newport Beach wells tank farm, at 5810 Pacific Coast Highway, was taken. This is the gas that is produced and sold to Hoag Hospital. The production is from the offshore oil reservoirs. In September of 1992 samples were also taken from the Newport Beach Townhomes. They are at the far west side of the Balboa Coves area at 4401 Coast Highway. There are four vent locations on this site. An attempt to sample the most recently installed vents, those that were installed in 1991 was made. There was insufficient gas flow from either -of these to assure a quality sample. The final ,sample was obtained from one of the two old non-functioning ornamental gas torches. The sample came from the torch on the right hand side of the front man gate, as one looks at it from the inside. i Hoag Memorial Hospital L. Thompson Page two The Hoag gas collection wells were sampled in nearly the same time frame. Wells number 5, 6, and 7A were sampled one at a time by closing in two wells and sampling the other well. New valve systems were installed on two of the wells prior to the sampling. This was needed due to leakage at some points and uncertainty in the isolation capabilities of the 1989 brass valves. There is a high probability that at least some of the brass valves, that were installed shortly after the wells were redrilled in 1989, are no longer functional. Some appear to be both frozen and corroded. Not all of them were checked or tested. This gas flow manifolding center will be replaced during the Lower Campus building project. No danger is caused by the valve condition. The samples were analyzed, using protocol EPA 8015. Their hydrocarbon components were measured in ppm (parts per million) by volume, from Cl through C6, which is methane, ethane, propane, butane, pentane and hexane. The remaining hydrocarbons above C6 are given as a total, and are designated as >C6. The other analyses which were also measured, in ppm for hydrogen sulfide gas and the atmospheric gases oxygen, nitrogen, and carbon dioxide. The British Thermal Units (BTU) value, a measure of heating quality, for each of the gases was also reported for some of the samples. A composite sample of gas that is presently burned in the Hoag Hospital flare was also taken from the flowline to the flare and analyzed. It is reported in Table I for comparison. The samples were taken in tedlar bags with a vacuum pump. The bags were filled and evacuated three times to get the final sample. Two samples were taken from each site and analyzed and an average obtained. The Del Mar Analytical Laboratory reporting data sheets and the Chain of Custody forms are included in the appendix. Table I is a summary of the reported data. (see Table I) These data show that the gases from the City oil wells and the Newport Townhomes are very different both from each other and from the Hoag Hospital collection wells. The data suggests that each source of gas is distinctive from the other. It is therefore unlikely that they -are a product of the fire flood. While this may be the case it is doubtful that all the areas gas sources are unrelated. The Newport City oil field gas is rich in the heavier gases and liquids and the other sources are not. This to be expected, but the extremely low methane content of the Newport Beach Townhomes Hoag Memorial Hospital L. Thompson Page three gas is unusual. The higher amounts of 02, N2, and CO2 are near atmospheric amounts and probably indicate a leak in the collection system. The Hoag collection wells do not show an atmospheric leak. The low oxygen and greater than atmospheric CO2 content may indicate bacterially derived or altered gases. The low levels of butane (C4) through the higher weight hydrocarbon gases is also an indication of a possible bacterial source. The analyses of the City wells are a typical example of the contents of oil reservoir gases. The wet and higher fraction gases are much more abundant. The composite sample, of the three (3) Hoag hospital wells, shows some unusual features. The occurrence of hydrocarbons C3 thru C6 and the higher than average nitrogen are both of special interest. The H2S amount is considerably higher than an average from the three wells. The fact that the most shallow producing well, #6, has the highest H2S reading may have some significance. It is possible that the reaction that forms the H S gas is taking lace near the surface and that the gases tiat are not high in H2S are from the deeper reservoirs. Some early studies concerning the formation of the hydrogen sulfide have related it to a reaction with sea water. Some of the conclusions that can be made concerning the source of these gases are as follows. The sources seem to vary. This is a very small sampling, but it is from three different locations and even with the collection problems the variation appears to be great enough to theorize that the gases are from three different sources. The Newport City wells exhibit a typical oil field gas analysis. The heavier hydrocarbons, C3 through C6 and above, are very evident. The oxygen, nitrogen, and carbon dioxide are not present in atmospheric quantities, and the hydrogen sulfide is present at a nominal level. The analyzed amount is high, but not as high as the Hoag collection wells. The Newport Townhomes samples are unusual, compared to the Hoag wells, in their lower methane level and their very low hydrogen sulfide content. The oxygen, nitrogen, and carbon dioxide are present in near atmospheric amounts. This is probably due to leakage in the old collection system, but the low methane and H2S indicate a source other than the Hoag site reservoir. Hoag Memorial Hospital L. Thompson Page four The fire flood West Newport oil Company area, to the north- west, may have been a minor contributor to the Hoag Hospital produced gases, but the recent evidence, that follows, would indicate the effect was minimal. The lease gas production during air injection was 10,000 MCP (Thousand Cubic Feet) per day. Now that injection has ceased, it is approximately 300 MCF/day, but no change in the Hoag wells production has been noticed in the two years since it has stopped. The gas produced at the fire flood has a BTU value of less than 200, the Hoag wellsf gas has always had a BTU value of 600 to 700. This should have decreased over the years as the theorized fire flood influence was felt. The fact that no resultant production or gas content change has been detected would strongly suggest that it is unlikely that the fire flood was having much effect on the Lower Campus gas. The Hoag Hospital wells have produced gas at approximately the same rate since the early 1970's. This fact and the differing gas analyses seem to indicate that the wells are in a separate source area from the other two sites that were studied. The collection wells are each some what different, but basically are more similar than the other two (2) tested gas sources. The collection well tests did show anomalies that were unexpected. For example well PA did not match wells #5 & 6 in the content of methane, oxygen, nitrogen, carbon dioxide, or hydrogen sulfide. The actual reason for this is unknown, but the producing interval, and well tests for previous well #3 & its replacement #7A, have always been different from the other two. The oxygen, nitrogen, and carbon dioxide content of any of the wells is not indicative of an atmospheric origin, and could be interpreted as by- products from bacterial action. The gas could either be formed by bacteria or' altered in its migration from the reservoir to the surface. The composite sample of the three (3) wells has variations in its content that do not correspond to any expected numerical average of the individual well tests. The majority of the production is from wells #5 & 46 so the reduced composite sample methane is probably too low. The average should be over 600 ppm. The reduced C2 (ethane) which is lower than the average of all the wells doesn't equate. The oxygen, nitrogen, and H S are all too high, but the carbon dioxide is near average so this increase is probably not caused by air leakage. The hydrogen sulfide is higher than a weighted average by a factor of approximately four. Sulfur deposits in some of the flare equipment lines may explain the H2S. Production slugging, where unequal amounts of gas of varying content are produced over a given period may also be the cause. Hoag Memorial Hospital L. Thompson Page five Past investigations indicate that the easterly portion of the Balboa Coves housing site, across Pacific Coast highway from the Hoag collection wells, is connected to and influenced by their gas production. If the well production is interrupted, the methane and HZS begin to show in the area very quickly. It is important that Hoag Hospital be allowed to continue the withdrawal of the gases. The early interpretation of the data acquired during this test would indicate that the fire flood is not the primary source of the gas produced from the Hoag Hospital Lower Campus. This assessment has to be made without an analysis of that area's gas, but the variability of gas content from site to site indicates a multiple rather than a singular source area. Thank you for this opportunity to be of assistance in Hoag Hospital's studies of the Lower Campus project. Sincerely i M. E.

Broadway, Suite 475 Long Beach, CA 90802 Dear Mr. Manuel: Recently Hoag Hospital Memorial Presbyterian received approval of its Master Plan and certification of its Environmental Impact Report. As part of the approval by the City of Newport Beach, certain conditions and mitigation measures were adopted. One of these measures concerns the investigation of the abandonment quality of well Exxon Newport #1, and other abandoned wells near the project. This mitigation measure reads as follows: #50 Prior to construction of structures over or near the Wilshire oil well, Project Sponsor shall ensure that the Wilshire oil well, or any abandoned, unrecorded well or pressure relief well, is reabandoned to the current standards. Abandonment plans will be sub- mitted to D.O.G. for approval prior to the abandonment procedures. The City's building official shall be notified that the re - abandonment was carried out according to D.O.G. procedures. We wish herewith to present the data on the abandonment quality of each well and petition your approval of our interpretation. There are seven (7) wells of different category near the Hoag Lower Campus property (see map). Three wells were production wells, or attempts at producing oil. Cagney #4 and #5 produced oil; they were abandoned in 1978. Exxon (Wilshire Oil) Newport #1 was a dry hole, and abandoned as such in 1935. The other four wells which are Hoag Memorial Hospital, State of California wells #5, #7A and City of Newport Beach State of California #3, and #4 are either productive gas pressure relief withdrawal wells, abandoned withdrawal wells, or investigative gas source test wells. No "unrecorded well" is known to exist. The Hoag Memorial Hospital State of California wells #5 and #7A are presently producing gas and are two of the three wells, along with #6, that are controlling the Balboa Coves - Lower Campus methane and H2S problem. No abandonment is required. The City of Newport Beach State of California wells #3 and #4 are abandoned. Well #3 was a producing location from 1976 until 1989 when it was abandoned to make way for the widening of Pacific Coast Highway. Mr. Rich Manuel November 9, 1992 Page Two It was originally drilled to 991. A productive gas sand was encountered at 83'. 7" casing was set at 99' with the bottom 16' shop perforated. When the well was abandoned the 7" casing was recovered and the hole filled with drilling mud up to 601. The remainder of the hole was filled with concrete up to within 8' of the surface. This well is abandoned according to current requirements of the Division of Oil and Gas. Well #4 was an investigative hole to determine if there were productive gas sand at that location. No gas sand was found in the 115' deep hole. Some H2S odor and minor amounts of methane were recorded emanating from the shale. The hole was abandoned by filling it with redimix concrete from 115' to within 2' of the surface. This well is abandoned according to the current requirements, no reabandonment is required. The three oil producing wells or wells which were attempts at producing are all abandoned. They are as follows: James and William Cagney #4 was drilled in 1948 to 1,2921. 5-1/2" liner was set at 1,290' with the top at 1,0121. Perforations were at 1,290' to 1,028' and 8-5/8" casing was cemented at 1,029' and 14" surface casing was cemented at 401. The well produced 9' gravity oil in late 1948 and early 1949. In 1978 the well was abandoned. It was cleaned out to 1,020' and squeeze cemented from there up to the surface. 1-1/2 yards of cement was added to fill the hole. This well is among the Versailles Apartments and is 390' straight back at right angles to the present bluff cliff. The abandonment is not up to current regulations due to the production perforations not being cemented off. The distance from the proposed upcoming building project precludes the need for its reabandonment. James and William Cagney #5 was drilled in 1948 to a total depth of 3,8781. It produced 90 gravity for approximately 7 months. 5-1/2" liner was set at 1,239' with the top at 1,0241. Perforations were from 1,239' to 1,0511. A cement plug had been placed from 1,395' to 1,2401. Other plugs were placed from 3,050' to 2,9071. 8-5/8" casing was cemented at 1,053' and 14" surface casing was cemented at 40'. The lower most potentially productive and water bearing sands below 1,400' should be sealed off. This is shown by the well's low 4% water cut during its production. In 1978 the well was abandoned. It was cleaned out to 1,1831. Three joints of tubing were stuck in the hole. Most of the 5-1/2" liner was recovered. The hole was cemented with 351 cu. ft. of cement from approximately 1,050' to the surface. This well is also among the Versailles Apartments and is 220' north of the bluff cliff and 180' east of the present flare location. The abandonment is not current with present Division of Oil and Gas requirements. The perforations are not cemented off. Its distance from the proposed building project should preclude the need for its reabandonment. Exxon Newport #1 was drilled in 1935 and never produced. This is the so called Wilshire oil well named in Measure #50. Mr. Rich Manuel November 9, 1992 Page Three "Newport" #1 was originally drilled in April of 1935 to a total depth of 1,9461. No electric log was run. A drillers log was kept and 13 cores were taken, at selected intervals, from 1,565' to 1,8671. The top 79' of coring detected six weak "heavy" oil shows that, according to the core description, had high water saturation and would not be economically productive. The drillers log, which is less precise than the core data but includes the complete well, found oil and gas shows at 5861, 9351, 962', 1,275', 1,540' and 1,548'. The show at 1,540' is described as "sandy shale showing lots of oil". No gas is mentioned. The show at 586' is described as "heaving (soft) sand with gas". No oil is mentioned. The well was originally, during drilling, cased from the surface with 10-3/4" casing to 1,9301. 13-3/8" casing was landed at 8871, and 18" conductor pipe was cemented at 141. In July of 1935 the hole was drilled to its total depth and the 10-3/4" casing recovered. The hole was filled with heavy mud. Attempted to recover the 13-3/8" casing, it did not come. The 13-3/8" casing was cemented with 10 sxs. of cement from 865' to 8481. The 13-3/8" was shot at 5761, 416' and 320'. It was recovered from 320'. This means that from at least 416' down to the bottom at 887', the casing is locked solid in the hole. The hole was filled with heavy mud from 848' to the surface. A wooden plug was driven into the open hole to 30'. The open hole and 18" casing were cemented from 30' to the surface (see well diagram). This description offers the present following hole conditions. The hole is open to 1,946'. It has thirteen (13) oil and gas shows. 13- 3/8" casing is stuck in the hole from 887' to 3201. There is a 17' cement plug in this casing from 865' to 848'. The hole above the cement plug is filled with heavy drilling mud. The hole is open formation from 320' to the shoe of the 18" surface casing. The hole is filled from 30' to the surface with a cement plug on a wooden plug to bridge off the hole. (see diagram). The following factors become apparent during an analysis of this well: 1. The well has some oil and gas shows in it. 2. The well is mostly mud filled open hole. The hole is open or non - cased from 1,946' to 887' and 320' to 181. 3. All, but one, of the reported oil and gas bearing sands are presently exposed in the open hole well bore. 4. Two cement plugs and heavy mud are protecting against the migration of gas and fluids up and down the hole. 5. The filling of the hole with heavy drilling mud should control oil or gas influx, as long as the reservoir pressures are maintained near hydrostatic or below. 6. Re-entering the old hole may not be possible due to the 300' length of open hole section above the top of the 13-3/8" casing. Y Mr. Rich Manuel November 9, 1992 Page Four It is highly unlikely that this well is the source of the gas in the flare area. If it were the major source leak, the gas presence in the well area of the bluff should be much more apparent. The likelihood of entering the hole to the oil and gas shows without casing to total depth, is very low. The reported heavy drilling mud fill left in the hole should be capable of containing gases and liquids up to and somewhat over hydrostatic pressure. The present building plans for the well area are that it will not have construction placed over or near it. It will be left in an open park setting. If the well should ever require work, its location will be highly accessible. It is my professional opinion and recommendation that this well does not, at this time, require reabandonment. It is the intent of the foregoing to offer the well data and analysis needed for your offices to make a decision as to the acceptance of the abandonment quality of these wells. We would ask that you either approve of the analysis by signing this document in the space provided or advise us, in writing, of your conditional approval or disapproval. If it is the latter, please include the well numbers and required changes. Sincerely, M. E.

This measure can be found in the city of Newport Beach Findings and Conditions for Approval for the Hoag Hospital Master Plan. This investigation was performed according to our proposal dated September 17, 1993 and as authorized by you on November 18,1993. Mitigation Measure # 67 states, " Prior to issuance of a grading permit, the project sponsor shall ensure that the inferred fault traversing the site is trenched and monitored for gas prior to site grading and construction. If gas monitoring indicates a potential risk during grading, additional gas collection wells will be drilled to collect and contain the gas." There are two inferred faults shown on the various maps of the Lower Campus. The northwesterly trace is unnamed and is shown on old Division of Oil and Gas Maps (Zebal, 1968), while the principally northerly trace is named the Balco fault (Zebal, 1976). The approximate locations of these inferred faults are shown on the Trench Location Plan (Plate A). 2.0 Purpose and Scope of Investigation This fault investigation was performed to attempt to locate two faults inferred to exist on the site based on previous investigations by Zebal and Associates (1968) and Leroy Crandall and Associates (1989). To locate these faults, we have orientated and exca- vated two trenches approximately perpendicular to the inferred trends, as mapped by others. The location of these exploratory trenches is shown on the attached Trench Location Plan, Plate A. The objectives of this study were accomplished by the following scope of work: 1. Review of available published geologic data, and private geologic investigations performed by other consultants. 2. Limited geologic mapping of the site and vicinity. 3. Gas monitoring during exploratory trenching. 4. Excavation of two exploratory trenches across the projected alignments of both inferred faults. 5. Geologic evaluations, data compilation and review; and preparation of this report and attached drawings, including conclusions and recommendations. 11321alt.gw Merrill E. Wright Page 1 Geological & Petroleum Consultant 3.0 Project Location The Hoag Hospital Master Plan Lower Campus project is located in the city of Newport Beach in Orange County, California. Specifically, the site is that area north of Pacific Coast Highway between Superior Avenue to the west and Hospital Drive to the east. The region of this investigation was limited to the northwest side of Hospital Drive. The location of the site and ifs relationship to the nearby streets and the Alquist - Priolo Special Studies Zones is shown on Figure 1. 4.0 Method and Description of Exploratory Trenching The two exploratory trenches were excavated approximately 7 to 8 feet deep and 24 to 30 inches wide using a John Deere backhoe equipped with a 24 inch bucket. As these trenches encountered bedrock at a fairly shallow depth, it was not necessary to ex- cavate the trenches as deep as originally planned. The orientation, location, and depth of each trench were measured using a Brunton compass, 100 foot measuring tape, levels, and leveling string. The location of the trenches is shown on the Trench Loca- tion Plan (Plate A) and were determined by measuring from known structures shown on the Trench Location Plan. Each trench was measured and stationed in 5 foot intervals to provide horizontal control during the investigation and trench logging. In addition, a leveling line was placed in each trench to establish vertical control. 5.0 Background and Regional Geologic Setting The site lies along the southern margin of the central block of the Los Angeles Physio- graphic Basin. The geologic structure is dominated by northwest -trending faults associated with the San Andreas system. Faults, such as the Newport -Inglewood, the Whittier -Elsinore, the San Jacinto, and the San Andreas, are major faults of this sys- tem. They are all known to be seismically active, and the San Jacinto, San Andreas, and Whittier -Elsinore faults are known to have ruptured the ground surface in historic time. As a result of the Alquist Priolo Special Studies Act of 1972, the State Geologist has delineated "Special Studies Zones" along known active faults. Cities or counties affected by the zoning must regulate development within the designated zones. Build- ing permits for sites within state designated zones must be withheld until geologic investigations demonstrate that a proposed development is not threatened by surface displacement from future fault movement (Hart,1992). 1132falt.gw Merrill E.

Based on the age of the rocks deformed or displaced, on the topographic expression within the zone, and on the large number of associated earth- quake epicenters, the age of faulting is youthful (Barrows,1974 and Bryant,1988). A small westerly portion of the site is included within the established Alquist-Priolo Special Studies Zone as shown on Figure 1. Aside from this area, no active or poten- tially active faults were detected within the site as mapped by Leroy Crandall and Associates during their geotechnical evaluation of the site in 1989. Figure 2 depicts the regional faulting within the general site vicinity. 6.0 Local Geologic and Geomorphic Conditions The project site is situated along the Northern side of Pacific Coast Highway between Superior Blvd, and Newport Blvd. The project site occurs as a narrow, relatively flat area bordered by an existing approximately 50 foot high, flat topped bluff to the east and by Pacific Coast Highway to the west. The moderately steep bluff is deeply eroded and incised by several shallow gullies and runnels . The Bluff has been interpreted as an ancient marine wave cut terrace which previously existed at the edge of Pacific Coast Highway, but has been cut back to its present location by excavation and borrow grading during the 1959s. Most of the current bluff exposes terrace deposits consist- ing of fine to medium grained, poorly to well bedded, white to light. grayish white sands, silty sands, and minor clayey siltstones. The unit contains occasional lenses of fossilif- erous sand containing mostly disarticulated bivalve shells. The distance from the base of the bluff to Pacific Coast Highway varies from 100 to 140 feet. As observed within our trenches, most if not all of the terrace deposits have been removed in the vicinity of the exploratory trenches. Terrace materials overlie the Miocene Monterey Formation bedrock along an old, nearly flat lying erosional contact which occurs approximately at the base of the bluff and is concealed by an extensive cattail wetland area that lies at the base of the bluff. The source of water for the wetlands is from groundwater seepage along the contact bet- ween the terrace materials and Monterey Formation. The Monterey Formation dips gently 5 to 15 degrees southwest within the project site. Beneath the site, The Monter- ey Formation is the apparent source of small quantities of natural gas, including hydro- gen sulfide gas, which is being produced from various sand horizons, that is currently being collected by three shallow wells. The gas from these wells currently flows through a series of pipes by a suction pump system and is then burned through a flare. These wells were installed in 1976 and have produced gas continuously up to this date. During 1989, two wells were relocated to allow widening of Pacific Coast Highway. 1132falt.gw Merrill E. Wright Page 3 Geological & Petroleum Consultant 7.0 Trench Observations 7.1 General The exploratory trenching exposed a surficial veneer of artificial fill overlying bedrock deposits within the depths explored. The artificial fill is essentially the same material as the Terrace deposits in the bluff face, but has been moved from its original location during the borrow grading which occurred at the site. The bedrock unit consists mostly of laminated to massive dark gray, slightly diatoma- ceous claystone and clayey siltstone with minor thin light. gray and brown sand beds, lenses, and stringers, and is referred to as the Monterey Formation. The bedrock is generally fresh to slightly weathered, but at some locations is moderately weathered up to a foot or more within the contact of the overlying artificial fill. The moderately weathered zone was also observed to contains trace amounts of secondary sulfur mineralization and un-identified yellow and orange oxide staining. The geologic features observed within each trench are shown on Plates B and C. 7.2 Trench No.1 Trench No. 1 was excavated across the northwesterly trace of Zebal's unnamed fault approximately 250 feet west of Hoag Hospital Drive. The location of this trench is shown on the Trench Location Plan (Plate A). Geologic mapping within this trench revealed the following: Northeast of Sta 0+68, unfauited bedrock was observed, evidenced by the presence of small mappable continuous sand stringers and beds within the Monterey Formation. These strata dip gently S to 10 degrees southwest. At Sta 0+68, a distinct and traceable bed of sand has been offset along a steeply dipping fault (southwest side up). Most of the movement along the fault appears to be vertical based on the uniform thickness of the marker bed across the fault. The fault appears as a approximately 1/16 to 1/2 inch wide zone of slickensided clay. Small elongated zones of cemented sand were also observed within the fracture zone. Southwest of Sta 0+68, the Monterey Formation is extensively jointed and fractured into a number blocks bounded by high angle fractures. Where discernible, sand stringers were observed to be offset from 1 /16 to a few inches. Some of the fracturingtfaulting (?) was accompanied by drag folding. A good example of drag folding occurs on the southwest side of first fault located southwest of Sta 0+68. Most of the sand stringers thin and thicken making these units difficult to follow. The rather indistinct nature of the beds made correlation between these beds and lens difficult to distinguish. Between Sta 0+97 to Sta 1+02, a highly sheared zone of claystone bedrock exists containing a 1132faltgw Merrill E. Wright Page 4 Geological $ Petroleum Consultant number of slickensided, "polished" clay surfaces, several of which intersect and cross- cut one another. The original bedrock structure of the typical Monterey claystone as typically seen outside this zone has been destroyed within this zone. The general trend of the fracture/fault surfaces within this zone range from N 80 W to N 85 E. Several areas of seepage were noted within the northwest wall of this trench. The source of water is likely derived from the adjacent wetlands. The water is seen to be percolating along the contact between the bedrock and artificial fill, and in some cases within the uppermost portion of the bedrock unit. No seepage was noted past the fault at Sta 0+68. 7.3 Trench No. 2 This trench was excavated east of Trench No. 1 and across Zebal's inferred "Balco fault'. Unlike Trench No. 1 , no continuous unfractured/faulted bedrock was noted for any appreciable distance along the the entire length of this trench. However, most of the fracturing/faulting observed consists of single, tight, high angle joints and fractures, with very few zones of sheared bedrock. in most cases, there is very little offset, and most of the sand stringers could be traced fairly easily across the fracture surfaces. Stratigraphic separations along many of the fractures and occasional drag folds in- dicate normal or reverse slip. A major exception to this is a sheared fault (?) zone which trends approximately N 17 E across the trench near Sta 1+10. Here, an approx- imately 2 inch thick sand marker bed has been offset a few feet. Evidence of horizontal movement is indicated by the non -uniform thickness of some marker sand beds on either side of this fault zone. A few sand marker beds adjacent to the fault zone have been drag -folded and smeared. In addition, differential deformation and shearing of the relatively incompetent claystone has destroyed most of the stratigraphic features within several inches of this fault. The bedrock adjacent to the fault fracture was chaotically slickensided. In addition, a slight hydrogen sulfide odor was apparent in fresh breaks of the claystone bedrock, which quickly dissipated. No measurable quantities of this gas could be detected with the monitoring device. Similar to Trench No. 1, seepage was noted in Trench No. 2 within the northwest wall of this trench. This was accompanied by precipitation of an unidentified rust -orange colored mineral upon coming in contact with the air. 1132falt.gw Merrill E. Wright Page 5 Geological & Petroleum Consultant 1 1";D01omICIA Our exploratory trenching indicates fairly wide zones of faulted bedrock which have not been fully delineated. Trench No. 1 revealed faulting, shearing and offset bedding within the Monterey Forma- tion which begins near Sta 0+68 and continues southwestward for an undetermined distance beyond the end of the exploratory trench. The initial faulting at Sta 0+68 occurs approximately 15 feet southwest of the inferred fault trace mapped by Zebal. The proximi- ty of the inferred westerly most Zebal fault (see Plate A) to this fault suggests that these two faults are the same. The inferred fault trends approximately N 62 W while the fault trace mapped at Sta 0+68 has a more westerly trend that ranges from N 75 W to N 85 W. Significant fracturing/jointing occurs throughout the length of Trench No. 2, However, a distinct sheared fracture zone trending approximately N 17 E occurs at Sta 1+10. This fracture occurs 35 feet southwest of the inferred Balco fault trace mapped by Zebal (1976)(see Plate A). With the exception of a few bedrock fractures, no zones of exten- sively sheared and faulted bedrock were noted near Sta 1+45 where the Zebal's Balco fault would intercept our exploratory trenching. As a complete sequence of unfractured bedrock was not found, the true location of the Balco fault may be located northeast of Trench No. 2. On the other hand, the significant sheared fracturing seen at Sta 1+10 may be the true location of the Balco fault and the minor fracturing on either side of this zone may be minor faulting associated with this main fracture. Attitudes of several frac- ture surfaces trend toward the northwest, which is similar to the inferred fault direction. As stated previously, the full width of faulting seen within each trench was not fully delineated through the exploratory trenching. The only zone of relatively unfractured/un- faulted bedrock occurs northeast of Sta 1+ 68 as shown within Trench No. 1. Limitations imposed by the existing wetlands precluded this investigation from extending northeast to the foot of the bluff where Pleistocene terrace deposits overlie the Monterey Formation. The lack of Holocene or Quaternary deposits within the trenches removed any direct evidence to determine the recency of activity of the observed faults. No offset was seen at the irregular contact that separates the thin veneer of artificial fill from the bedrock. Geologic reconnaissance of the bluffs and surrounding flat area east of the bluff face did not disclose any offset beds or any geomorphic escarpments along the general trend of the observed faulting. Previous mapping by Leroy Crandall and Associates(1989) also found no evidence of faulting within the Terrace deposits, or on the exposed bluff face. Faulting of the Pleistocene terrace deposits against the Monterey Formation approximate- ly 850 feet west of Trench No. 1 was noted by Leroy Crandall and Associates (1989), Zebal (1968), and this firm. This would make this fault potentially active under the guide- lines of the Alquist-Priolo Zone Special Studies Zones Act. As defined by this act, a fault is potentially active if it shows evidence of surface displacement within Quaternary time (1.6 million years)(Hart,1992). 1132fatt.gw Merrill E. Wright Page 6 Geological & Petroleum Consultant The top of the bluff has been altered by recent construction activity and grading which has eliminated any geomorphic expression of faulting. Due to the complexity of the Newport -Inglewood fault zone, no attempt was made to correlate the observed faulting to any of the mapped fault traces seen within the Alquist Priolo Special Studies Zone located approximately 850 feet west of Trench No.1 near the property corner. The overall regional faulting in the west Newport Beach area is shown on Figure 2. Results of Gas Monitoring During excavation, each trench was monitored for hydrogen sulfide gas and combustible gases (methane, etc.) using a Gas Tech Safe T Mate, type 102 and Neotronics Digiflam 2000 gas monitoring devices respectively. The 1-12S detector is capable of detecting hydrogen suede (1-12S) in the range of 0 to 500 parts per million (ppm); whereas the combustible gas detector responds to gas concentrations from .0005% to 100%, by volume. Continuous monitoring during trench excavation and during geologic inspection did not reveal measurable and sustained amounts of 1-12S or combustible gas. However, a brief but short lived quantity of 1-12S gas was detected with the monitoring device within Trench No. 2 at Sta 1+44. Occasionally, faint traces of 1-12S gas could be detected by odor when fresh bedrock was fractured with a rock hammer. These trace amounts of gas quickly dissipated into the atmosphere and could not be detected by the monitoring device. Careful monitoring for H2S and combustible gases were also performed along zones of fracturing and faulting with no measurable amounts of 1-12S or combustible gas noted. 9.0 CONCLUSIONS The exploratory trenches have revealed zones of fracturing/faulting which may be the same faults as those mapped previously by Zebal and others. The fracturing observed within our trenches appears confined to the Miocene Monterey Formation. As previously mentioned, only a slight odor of Hydrogen Sulfide gas was detected within the exploratory trenches and with the exception of a brief measured amount of Hydrogen Sulfide gas at Sta 1+44 within Trench No. 2, no measurable or sustained amounts of combustible gas or Hydrogen Sulfide gas were detected within the trenches or along the zones of fracturing. Grading that does not exceed the trenching depths should be relatively safe from gas hazards. Based on the our observations, additional drilling of gas collection wells is not warranted at this time. 1132falt.gw Merrill E. Wright Page 7 Geological & Petroleum Consultant In any case, it is recommended that all deep utility trenches and other confined excava- tions be monitored for Hydrogen sulfide and combustible gases prior to entry to detect the presence of these gases. The main H2S production is from thick sand beds located at approximately 80 feet below existing grade in Wells #5, and VA. At well #6, hydrogen sulfide production comes from sand layers found between 15.0 and 52 feet below exist- ing grade. No thick sand beds were observed during our exploratory trenching. If thick sand strata are encountered during future excavation, special care should be taken to. check for H2S and methane. The risks involved and ultimate decisions should be careful- ly determined by the owner and applicable governing agencies. We feel that this investigation has sufficient detail to meet the intent of Mitigation Meas- ure # 67. The conclusions and opinions contained in this report are based on the results of the described geotechnical evaluations and represent our best professional judgment. This report is issued with the understanding that it is the responsibility of the owner or his representative to insure that interested parties have this information.

Figure 2 depicts the regional faulting within the general site vicinity. 6.0 Local Geologic and Geomorphic Conditions The project site is situated along the Northern side of Pacific Coast Highway between Superior Blvd. and Newport Blvd. The project site occurs as a narrow, relatively flat area bordered by an existing approximately 50 foot high, flat topped bluff to the east and by Pacific Coast Highway to the west. The moderately steep bluff is deeply eroded and incised by several shallow gullies and runnels . The Bluff has been interpreted as an ancient marine wave cut terrace which previously existed at the edge of Pacific Coast Highway, but has been cut back to its present location by excavation and borrow grading during the 1950's. Most of the current bluff exposes terrace deposits consist- ing of fine to medium grained, poorly to well bedded, white to light. grayish white sands, silty sands, and minor clayey siltstones. The unit contains occasional lenses of fossilif- erous sand containing mostly disarticulated bivalve shells. The distance from the base of the bluff to Pacific Coast Highway varies from 100 to 140 feet. As observed within our trenches, most if not all of the terrace deposits have been removed in the vicinity of the exploratory trenches. Terrace materials overlie the Miocene Monterey Formation bedrock along an old, nearly flat lying erosional contact which occurs approximately at the base of the bluff and is concealed by an extensive cattail wetland area that lies at the base of the bluff. The source of water for the wetlands is from groundwater seepage along the contact bet- ween the terrace materials and Monterey Formation. The Monterey Formation dips gently 5 to 15 degrees southwest within the project site. Beneath the site, The Monter- ey Formation is the apparent source of small quantities of natural gas, including hydro- gen sulfide gas, which is being produced from various sand horizons, that is currently being collected by three shallow wells. The gas from these wells currently flows through a series of pipes by a suction pump system and is then burned through a flare. These wells were installed in 1976 and have produced gas continuously up to this date. During 1989, two wells were relocated to allow widening of Pacific Coast Highway. 1132falt.gw Merrill E. Wright Page 3 Geological & Petroleum Consultant L 7.0 Trench Observations 7.1 General The exploratory trenching exposed a surficial veneer of artificial fill overlying bedrock deposits within the depths explored. The artificial fill is essentially the same material as the Terrace deposits in the bluff face, but has been moved from it's original location during the borrow grading which occurred at the site. The bedrock unit consists mostly of laminated to massive dark gray, slightly diatoma- ceous claystone and clayey siltstone with minor thin light. gray, and brown sand beds, lenses, and stringers, and is referred to as the Monterey Formation. The bedrock is generally fresh to slightly weathered, but at some locations is moderately weathered up to a foot or more within the contact of the overlying artificial fill. The moderately weathered zone was also observed to contains trace amounts of secondary sulfur mineralization and un-identified yellow and orange oxide staining. The geologic features observed within each trench are shown on Plates B and C. 7.2 Trench No.1 Trench No. 1 was excavated across the northwesterly trace of Zebal's unnamed fault approximately 250 feet west of Hoag Hospital Drive. The location of this trench is shown on the Trench Location Plan (Plate A). Geologic mapping within this trench revealed the following: Northeast of Sta 0+68, unfaulted bedrock was observed, evidenced by the presence of small mappable continuous sand stringers and beds within the Monterey Formation. These strata dip gently 5 to 10 degrees southwest. At Sta 0+68, a distinct and traceable bed of sand has been offset along a steeply dipping fault (southwest side up). Most of the movement along the fault appears to be vertical based on the uniform thickness of the marker bed across the fault. The faun appears as a approximately 1/16 to 112 inch wide zone of slickensided clay. Small elongated zones of cemented sand were also observed within the fracture zone. Southwest of Sta 0+68, the Monterey Formation is extensively jointed and fractured into a number blocks bounded by high angle fractures. Where discernible, sand stringers were observed to be offset from 1/16 to a few inches. Some of the fracturing/faulting (?) was accompanied by drag folding. A good example of drag folding occurs on the southwest side of first fault located southwest .of Sta 0+68. Most of the sand stringers thin and thicken making these units difficult to follow. The rather indistinct nature of the beds made correlation between these beds and lens difficult to distinguish. Between Sta 0+97 to Sta 1+02, a highly sheared zone of claystone bedrock exists containing a 1132laltgw Merrill E. Wright Page 4 Geological & Petroleum Consultant number of slickensided, "polished" clay surfaces, several of which intersect and cross- cut one another. The original bedrock structure of the typical Monterey claystone as typically seen outside this zone has been destroyed within this zone. The general trend of the fracturetfault surfaces within this zone range from N 80 W to N 85 E. Several areas of seepage were noted within the northwest wail of this trench. The source of water is likely derived from the adjacent wetlands. The water is seen to be percolating along the contact between the bedrock and artificial fill, and in some cases within the uppermost portion of the bedrock unit. No seepage was noted past the fault at Sta 0+68. 7.3 Trench No. 2 This trench was excavated east of Trench No. 1 and across Zebal's inferred "Balco fault'. Unlike Trench No. 1 , no continuous unfractured/faulted bedrock was noted for any appreciable distance along the the entire length of this trench. However, most of the fracturing/faulting observed consists of single, tight, high angle joints and fractures, with very few zones of sheared bedrock. In most cases, there is very little offset, and most of the sand stringers could be traced fairly easily across the fracture surfaces. Stratigraphic separations along many of the fractures and occasional drag folds in- dicate normal or reverse slip. A major exception to this is a sheared fault (?) zone which trends approximately N 17 E across the trench near Sta 1+10. Here, an approx- imately 2 inch thick sand marker bed has been offset a few feet. Evidence of horizontal movement is indicated by the non -uniform thickness of some marker sand beds on either side of this fault zone. A few sand marker beds adjacent to the fault zone have been drag -folded and smeared. In addition, differential deformation and shearing of the relatively incompetent claystone has destroyed most of the stratigraphic features within several inches of this fault. The bedrock adjacent to the fault fracture was chaotically slickensided. In addition, a slight hydrogen sulfide odor was apparent in fresh breaks of the claystone bedrock, which quickly dissipated. No measurable quantities of this gas could be detected with the monitoring device. Similar to Trench No. 1, seepage was noted in Trench No. 2 within the northwest wall of this trench. This was accompanied by precipitation of an unidentified rust -orange colored mineral upon coming in contact with the air. 1132faltgw Merrill E. Wright Page 5 Geological,& Petroleum Consultant 8.0 FINDINGS Our exploratory trenching indicates fairly wide zones of faulted bedrock which have not been fully delineated. Trench No. 1 revealed faulting, shearing and offset bedding within the Monterey Forma- tion which begins near Sta 0+68 and continues southwestward for an undetermined distance beyond the end of the exploratory trench. The initial faulting at Sta 0+68 occurs approximately 15 feet southwest of the inferred fault trace mapped by Zebal. The proximi- ty of the inferred westerly most Zebal fault (see Plate A) to this fault suggests that these two faults are the same. The inferred fault trends approximately N 62 W while the fault trace mapped at Sta 0+68 has a more westerly trend that ranges from N 75 W to N 85 W. Significant fracturing/jointing occurs throughout the length of Trench No. 2, However, a distinct sheared fracture zone trending approximately N 17 E occurs at Sta 1+10. This fracture occurs 35 feet southwest of the inferred Balco fault trace mapped by Zebal (1976)(see Plate A). With the exception of a few bedrock fractures, no zones of exten- sively sheared and faulted bedrock were noted near Sta 1+45 where the Zebal's Balco fault would intercept our exploratory trenching. As a complete sequence of unfractured bedrock was not found, the true location of the Balco fault may be located northeast of Trench No. 2. On the other hand, the significant sheared fracturing seen at Sta 1+10 may be the true location of the Balco fault and the minor fracturing on either side of this zone may be minor faulting associated with this main fracture. Attitudes of several frac- ture surfaces trend toward the northwest, which is similar to the inferred fault direction. As stated previously, the full width of faulting seen within each trench was not fully delineated through the exploratory trenching. The only zone of relatively unfractured/un- faulted bedrock occurs northeast of Sta 1+ 68 as shown within Trench No. 1. Limitations imposed by the existing wetlands precluded this investigation from extending northeast to the foot of the bluff where Pleistocene terrace deposits overlie the Monterey Formation. The lack of Holocene or Quaternary deposits within the trenches removed any direct evidence to determine the recency of activity of the observed faults. No offset was seen at the irregular contact that separates the thin veneer of artificial fill from the bedrock. Geologic reconnaissance of the bluffs and surrounding flat area east of the bluff face did not disclose any offset beds or any geomorphic escarpments along the general trend of the observed faulting. Previous mapping by Leroy Crandall and Associates(1989) also found no evidence of faulting within the Terrace deposits, or on the exposed bluff face. Faulting of the Pleistocene terrace deposits against the Monterey Formation approximate- ly 850 feet west of Trench No. 1 was noted by Leroy Crandall and Associates (1989), Zebal (1968), and this firm. This would make this fault potentially active under the guide- lines of the Alquist-Priolo Zone Special Studies Zones Act. As defined by this act, a fault is potentially active if it shows evidence of surface displacement within Quaternary time (1.6 million years)(Hart,1992). 1132fattgw Merrill E. Wright Page 6 Geological 8 Petroleum Consultant u - I The top of the bluff has been altered by recent construction activity and grading which has eliminated any geomorphic expression of faulting. Due to the complexity of the Newport -Inglewood fault zone, no attempt was made to correlate the observed faulting to any of the mapped fault traces seen within the Alquist Priolo Special Studies Zone located approximately 850 feet west of Trench No.1 near the property corner. The overall regional faulting in the west Newport Beach area is shown on Figure 2. Results of Gas Monitoring During excavation, each trench was monitored for hydrogen sulfide gas and combustible gases (methane, etc.) using a Gas Tech Safe T Mate, type 102 and Neotronics Digiflam 2000 gas monitoring devices respectively. The 1-12S detector is capable of detecting hydrogen sulfide (1-12S) in the range of 0 to 500 parts per million (ppm); whereas the combustible gas detector responds to gas concentrations from .0005% to 100%, by volume. Continuous monitoring during trench excavation and during geologic inspection did not reveal measurable and sustained amounts of 1-12S or combustible gas. However, a brief but short lived quantity of H2S gas was detected with the monitoring device within Trench No. 2 at Sta 1+44. Occasionally, faint traces of 1-12S gas could be detected by odor when fresh bedrock was fractured with a rock hammer. These trace amounts of gas quickly dissipated into the atmosphere and could not be detected by the monitoring device. Careful monitoring for H28 and combustible gases were also performed along zones of fracturing and faulting with no measurable amounts of H2S or combustible gas noted. 9.0 CONCLUSIONS The exploratory trenches have revealed zones of fracturing/faulting which may be the same faults as those mapped previously by Zebal and others. The fracturing observed within our trenches appears confined to the Miocene Monterey Formation. As previously mentioned, only a slight odor of Hydrogen Sulfide gas was detected within the exploratory trenches and with the exception of a brief measured amount of Hydrogen Sulfide gas at Sta 1+44 within Trench No. 2, no measurable or sustained amounts of combustible gas or Hydrogen Sulfide gas were detected within the trenches or along the zones of fracturing. Grading that does not hazards. Based on the warranted at this time. exceed the trenching depths should be relatively safe from gas our observations, additional drilling of gas collection wells is not 1132falt.gw Merrill E. Wright Page 7 Geological & Petroleum Consultant � w . In any case, it is recommended that all deep utility trenches and other confined excava- tions be monitored for Hydrogen sulfide and combustible gases prior to entry to detect the presence of these gases. The main H2S production is from thick sand beds located at approximately 80 feet below existing grade in Wells #5, and VA. At well #6, hydrogen sulfide production comes from sand layers found between 15.0 and 52 feet below exist- ing grade. No thick sand beds were observed during our exploratory trenching. If thick sand strata are encountered during future excavation, special care should be taken to check for H2S and methane. The risks involved and ultimate decisions should be careful- ly determined by the owner and applicable governing agencies. We feel that this investigation has sufficient detail to meet the intent of Mitigation Meas- ure # 67. The conclusions and opinions contained in this report are based on the results of the described geotechnical evaluations and represent our best professional judgment. This report is issued with the understanding that it is the responsibility of the owner or his representative to insure that interested parties have this information.

September 2, 1997 TO: Commissioners & Interested Persons FROM: South Coast District Staff SUBJECT: Commission Application No. eeting of Tuesday September No. 5-92-368 A(oagHopital)1 Hospital), 997. e Newport Beach, Orange County. The attached three letters of objection were received in the South Coast District office on September 2, 1997. The fourth letter, also attached. was receivedtember the project based7 and uonorts viewshlookingsfromrtownhomeshe first located across Coast Highway to the project and based on the sulfur and methane smell emanating from the project. The second and third letters object to the project based on obnoxious odors associated with the project and to receiving the public heohearingnotice hless than in two weeks prior to the hearing date and also Regarding the ob action based on views from the townhomes to the site: as proposed the pro ect will be screened from views from Coast Highway with fencing and vegetation and so will not create adverse impacts to public views. Regarding the objection based on odors produced by the project: the existing gas flare burns off the gas without first removing the sulfur content in the gas. The proposed project would remove sulfur compounds from the gas, principally hydrogen sulfide, to a Leval of 5.0 ppm from the current level of 4,DOD ppm. Consequently. the proposed project would most likely result in a decrease in noxious odors from the gas flare. Methane gas alone has no odor. Regarding the timing of the public hearing notice and the locatioh of the hearing: the public hearing notice was mailed out on 8/28197, eleven days prior to the hearing date of 9/9197. The California Code of Regulations requires that notice be dispatched no later than 10 days preceding the meeting. The proposed project was noticed consistent with the Regulations and the Commission's standard practice. The existing gas elimination system is deteriorated. If the existing system were to fail, dangerous gas accumulation would result. For this reason, the South Coast Air Quality Management District (SCAQMD) has requested, in a letter dated July 18, 1997 (attached to the staff the subject eamendment. Inport as tadditiont the SCAQMDthe shis indicated ion expedite tthat he rdelaying °f the project will adversely impact air quality, in that the existing gas flare allows significantly more sulfur to enter the air than is allowable by SCAQMD regulations. The proposed project will reduce the sulfur content emitted into the air. Consequently, Commission staff agendized the proposed project at the next available hearing after the application was deemed complete, The next available hearing was the September Eureka hearing. 2628F 09-08-1997 07:09AM FROM TO p as 6443250 P.04 wr 3S. 0.
