PUBLIC HEA~ING PCS-89-12 - Consideration of tentative subdivision map for Sun-Up Vista, Chula Vista Tract 89-12 - Gold Key Development (Continued) A. BACKGROUND 1. The applicant has submitted a tentative subdivision map known as Sun-Up Vista, Chula Vista Tract 89-12, proposing to subdivide 2.31 acres located on the south side of Telegraph Canyon Road, east of Hilltop Drive, into 9 single family lots. The property includes an existing house at 66 Telegraph Canyon Road and extends easterly approximately 600 ft. 2. The Environmental Review Coordinator conducted an Initial Study, IS-89-74, of potential environmental impacts associated with the implementation of the project. Based on the attached Initial Study and comments thereon, if any, the Coordinator has concluded that there would be no significant environmental impacts, and recommends adoption of the Negative Declaration issued on IS-89-74. 3. This item was continued from the meeting of August 23, 1989, so that the Commission could be provided with a soils report which was missing from the prior packet. The motion (6-0) was to continue the item but not reopen the public hearing B. RECOMMENDATION 1. Based on the Initial Study and comments on the Initial Study and Negative Declaration, find that this project will have no significant environmental impacts and adopt the Negative Declaration issued on IS-89-74. 2. Based on the findings contained in Section "E" of this report, adopt a motion recommending that the City Council approve the tentative subdivision map for Sun-Up Vista, Chula Vista Tract 89-12, subject to the following conditions: a. The panhandle area shall be reduced to two lots with contoured grading along the southeasterly boundary subject to staff review and approval. b. The dwellings shall be resited and/or the floor plans or lot lines adjusted in order to provide adequate, usable yard space for each lot subject to staff review and approval. Sideyards meeting this requirement shall have a minimum dimension of 15 ft. C&CR's shall be recorded with a city being a party thereto, prohibiting future building construction within the 15' sideyard. Said construction may exclude patios with an open trellis design approved by the City. City Planning Con~nission Agenda Items for Meeting of September 13, 1989 Page 2 c. Fully automatic fire sprinkler systems shall be installed in the "panhandle" dwellings subject to approval of the Fire Marshal. d. The approval of a final map by the City Council will require compliance with the City's adopted threshold standards to the satisfaction of the Director of Planning. e. The developer shall be responsible for the construction of street improvements in Telegraph Canyon Road as shown on the Tentative Map. Said improvements shall include, but not be limited to asphalt pavement and base, concrete curb, gutter and sidewalk, street lights, sanitary sewer, fire hydrants and potable water facilities. Required improvements shall be installed along the entire subdivision frontage and shall extend to the existing concrete curb easterly of the property. f. The developer shall dedicate to the City additional right-of-way along the south side of Telegraph Canyon Road adjacent to the subdivision as shown on the Tentative Subdivision Map. g. The private access drive off Telegraph Canyon Road shall meet City standards for intersection sight distance. h. The developer shall provide a concrete low flow channel in the tributary water course at the rear of Lots 2 and 3 unless the City Engineer determines that such a channel is not necessary. A drainage study shall be submitted to demonstrate the adequacy of the channel and to demonstrate that the channel is compatible with upstream improvements. i. Side slopes in the major drainage channel shall be no steeper than 2:1 (horizontal to vertical ratio) unless approved by the City Engineer. j. Access shall be provided to all storm drain structures including low flow channels adjacent to back of lots. The form and type of access is to be approved by the City Engineer. k. The property owner shall grant an easement to the City to provide for maintenance of the major Telegraph Canyon Channel. Said easement shall be granted on the Final Subdivision Map. 1. Specific methods of handling storm drainage are subject to detailed approval by the City Engineer at the time of submission of improvement and grading plans. Design shall be accomplished on the basis of the requirements of the Subdivision Manual and the Grading Ordinance ()~o. 1797 as amended). m. The developer shall obtain notarized letters of permission for all off-site grading work prior to issuance of grading permit for work requiring said off-site grading. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 3 n. The developer shall grant to the City a street tree planting and maintenance easement along Telegraph Canyon Road. Said easement shall extend from the property line to a line 10 feet from the back of the sidewalk. o. The developer shall provide access on an equal basis to and upon individual lots for all franchised cable television companies. p. Plans for the bridge providing access to Lots 1, 2 and 3 shall be reviewed by the City Engineer. Said bridge shall be capable of allowing a lO0-year storm flow to pass without obstructing said flow. q. The developer shall provide barriers on the portion of the exposed sewer line crossing the property subject to review and approval of the Director of Public Works. C. DISCUSSION Existing site characteristics. The property is an irregularly-shaped site which fronts on Telegraph Canyon Road and is bounded by single family homes to the south, east and west, and Hilltop Junior High School to the north. The site and surrounding areas are zoned R-1. An existing single family dwelling occupies the westerly portion of the property. The site has approximately 600 ft. of frontage on Telegraph Canyon Road, with an average depth of over 100 ft. and a maximum depth of 250 ft. at the easterly portion of the property. An unimproved drainage way traverses the length of the property approximately 75 ft. back from the street frontage. The abutting single family homes to the south and east are generally elevated well above the site with the exception of two homes which adjoin the southeasterly extension of the property. Tentative map. The tentative map shows 9 lots, 6 with frontage on Telegraph Canyon Road, and 3 lots on the southeasterly extension of the property served by a private drive. The drainage channel would be improved and a bridge would be constructed at the easterly boundary to provide access to the 3 panhandle lots. The average lot size is over 9,000 sq. ft., with only one lot below 7,000 sq. ft. The site plan shows the construction of 8 dwellings in addition to the existing dwelling which will remain on the most westerly lot. The dwellings are all two-story plans with 3-car garages, with the exception of two of the "panhandle" dwellings which show 2-car garages. The dwellings along the street frontage are planned with wider sideyards in order to compensate for the channel and resulting lack of usable rearyards. The 3 panhandle lots are served by 5 guest parking spaces. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 4 D. ANALYSIS All of the lots meet the dimensional requirements of the R-1 zone, and there are no requested deviations from the underlying R-1 development standards. Two concerns are with the development of the panhandle area and the provision of usable yard space. The panhandle area is the steepest portion of the site and requires extensive earthwork. This results in a series of manufactured slopes and retaining walls, and a severely constrained site plan with regard to access, parking, and the interface with the abutting dwellings to the south and east. We have recommended that this area be limited to only two rather three lots, subject to staff review and approval, and including provision for contoured grading of the southeasterly slopes. Several of the lots have limited usable yard area. We do not oppose the substitution of an ample sideyard for rearyard space, but we believe such an area should provide a minimum dimension of 15 ft. This would require resiting the dwellings and/or adjustments to the floor plans or lot lines. We have recommended any adjustments be subject to staff review and approval with the further intent to retain privacy for adjoining dwellings. The Commission had several questions of staff regarding issues raised in two letters from abutting property owners (please see letters attached). The issues and staff responses are as follows: 1. The existence of fill and/or ground water may adversely effect drainage and adjoining properties. The soils report found that all soils encountered on the site are suitable for reuse as compacted fill provided they are cleaned of trash and debris. All findings of the soils report are required to be incorporated into the grading plan for the project. No groundwater was observed in three test pits, nor any seepage along the southerly boundary or southeast portion of the site. 2. Chimney discharge from the proposed dwellings will create a fire hazard because of the combined effects of the topography and prevailing winds. Chimney spark arrestors are required for all dwellings, and represent almost a 100% deterrent to embers escaping into the atmosphere. For the occasional ember that does escape, combustibility is maintained for a distance of approximately 30 ft. As a result, almost all roof fires resulting from chimney embers originate from the dwelling itself. According to the Fire Marshal, the existing brush on the site represents a much greater fire hazard than chimney embers. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 5 3. Adequacy/maintenance of the drainage swale at the rear of lots 2 and 3. The treatment of this channel is addressed by Condition "h," which requires a drainage study and improvements if necessary. The 10 ft. maintenance drive into the main channel at the rear of lot 4 will provide convenient access to the tributary channel as well. The Commission also raised concerns regarding flooding downstream from the project, through Hilltop Park and at First Avenue. The Engineering Department has provided an exhibit of the flood elevations in the area and will be prepared to answer any questions at the meeting. E. FINDINGS Pursuant to Section 66473.5 of the Subdivision Map Act, the tentative subdivision map for Sun-Up Vista, Chula Vista Tract 89-12, is found to be in conformance with the various elements of the City's General Plan based on the following: 1. The site is physically suitable for residential development and the proposal conforms to all standards established by the City for such projects. 2. The design of the subdivision will not affect the existing improvements -- streets, sewers, etc. -- which have been designed to avoid any serious problems. 3. The project is in substantial conformance with the Chula Vista General Plan Elements as follows: a. Land Use - The proposal as conditioned is consistent with the General Plan designation of Low-~edium Residential (3-6 du/ac), and General Plan policies related to grading and landform. b. Circulation - Telegraph Canyon Road and the private drive shall be improved in accordance with City Standards. The reduction of one lot in the panhandle area will improve circulation for those lots. c. Housing The project shall provide single family, detached housing consistent with that in the immediate area. d. Conservation - The biologic component of the site is not unique and does not contain threatened or endangered species. There are no significant impacts with regard to wildlife habitat, soils or ground water. e. Park and Recreation, Open Space - The project shall be required to pay park acquisition and development fees prior to approval of a final map. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 6 f. Seismic Safety - No faults or landslides are known to exist on the project site. the La Nacion Fault Zone, located approximately 800 feet west of the property, has little potential as a source for a damaging earthquake. §. Safety - The project site is within threshold standards for both police and fire protection, the panhandle dwellings will be equipped with indoor sprinkler systems in lieu of adequate access for fire equipment. h. Noise - The site is not subject to adverse noise impacts. i. Scenic Highway - The property does not adjoin a scenic route or gateway. j. Bicycle Routes - The property does not adjoin a designated bike route. k. Public Buildings - The project is subject to the payment of school impact fees prior to the issuance of building permits. 4. Pursuant to Section 66412.2 of the Subdivision Map Act, the Commission certifies that it has considered the effect of this approval on the housing needs of the region and has balanced those needs against the public service needs of the residents of the City and the available fiscal and environmental resources. 5. The general orientation of the dwellings is conducive to passive and natural heating opportunities. The wide sideyards will allow for natural cooling to a greater extent than typically found.

Project Setting The 2.31 a~re project site is found on rolling terrain astride an existing improved drainage channel. On site elevation ranges from approximately 145 feet on the northwest to a maximum of 175 feet above mean sea level (MSL) on the southeastern portion of the site. Telegraph Canyon Road borders the site on the north and serves as frontage for lots 4 through 9. Average natural slope is approximately 8%; maximum natural slope is approximately 20% on the southeastern portion of the site. The project site is underlain by the Bay Point Formation and unnamed undifferentiated near shore marine sandstone, characterized by poorly consolidated, fine- to medium-grained fossiliferous sandstone. No faults or landslides are known to exist on project site, although the La Nacion Fault Zone is located approximately 800 feet west of the property. The Elsinore and San Jacinto Faults, located some 44 to 68 miles, respectively, north-northeast of the property have the greatest potential as a source for damaging earthquakes. The Olivenhain and Salinas soil series are represented on the project site. The Olivenhain soil series has developed on marine terraces and exhibits a loamy texture within a cobbly matrix. The Salinas soil series exhibits clay loam texture and has a moderate to severe expansive potential. Vegetation occurring onsite is a mixture of naturally occurring chaparral species and native and introduced weedy species. The site is currently vacant, with uses limited to passive open space functions and for storm drainage. Existing land uses in the vicinity of the project include single family residential development to the south, east and west. School recreation fields are located to the north across Telegraph Canyon Road Zoning for the site and surrounding residential areas is R-l. city of chula vista planning department CI~'OF environmental review section CHUM B. Project Description The proposed project consists of a subdivision of the 2.31 acre parcel into 9 separate building lots. Lots 1 through 3 are located across the concrete channel; access will be provided by a bridge and 20 foot wide private drive. Lots 4 through 9 will enjoy access from frontage with Telegraph Canyon Road. Lot 9 will retain an existing two-story single family residence. Site grading necessary to develop the project site includes the placement of approximately lO,O00 cubic yards of fill material. The maximum cut will be 8 feet although the project average is only 3 feet. Average fill depths are approximately 5 feet with a maximum of lO feet on lot 2. Hook-up to utilities will require the extension of gas lines, tie-in to sewer and water located on Telegraph Canyon Road. C. Compatibility with Zonin~ and Plans Current zoning for the project site is R-1. This zone is intended for single-family residential uses and allows for the construction of one single-family dwelling per legal lot. D. Compliance with the Threshold/Standards Policy 1. Fire/EMS The proposed Sun-Up Vista development is within 1 mile of the nearest fire station, Station 2 located a 80 E. "J" Street. Response times for emergency calls would be 5 minutes, which is less than the required ? minutes necessary to meet Threshold Standards. This area also would enjoy response from Station 1, located at 447 "F" Street and Station 3 located at 266 E. Oneida Street. The proposed driveway for lots 1, 2, and 3 is inadequate for Fire Department access. The Fire Department allows alternatives for these situations where indoor sprinkler systems may be used in lieu of access requirements. The applicant has elected to equip all dwellings which are greater than 120 feet from the nearest access point with indoor sprinkler systems. The project will also require the installation of one additional fire hydrant. 2. Police The City of Chula Vista Police Department was contacted and indicated that service could be provided for the proposed development. 3. Traffic Access to the proposed project would be off of Telegraph Canyon Road. The proposed project would impact area streets with the addition of approximately 80 average daily trips (ADT). The ADT on Telegraphy Canyon Road would be expected to increase from the existing 3,720 ADT to 3,800 ADT. The level of service at area intersections and roadways would not be significantly reduced. The City Engineer is requiring street improvements along the eastern half of the project. The distance from the Center Line of Telegraph Canyon Road to the face of the curb shall be constructed to a full 26 foot width. No parking will be allowed on Telegraph Canyon Road. 4. Park/Recreation The proposed project is located west of 1-805. Therefore the City of Chula Vista Threshold Standards do not apply. 5. Drainage Portions of the proposed project lie within the 100 year flood plane of the concrete swale which disects the project site. The concrete swale is adequate to handle runoff from the 100 year storm. All building sites are above the lO0 year flood level. 6. Sewer The desired sewer service connection for the project would be through a connection with a 21 inch sewer main located beneath Telegraph Canyon Road. The proposed project would be expected to generate approximately 6,000 gallons per day of liquid wastes. Sewer service for the site is adequate for the designs of the proposed project. 7. Water The Sweetwater Authority was contacted in regards to water service. They indicated that the project was within their service area and that service could be provided. 8. Schools The project would increase school enrollment in area schools. The following table shows the projected increases that may be expected from this project: Current Students Generated School Attendance Capacity From Project Elem. Cook 465 465 4.8 Jr. High Hilltop 1378 1506 2.7 Sr. High Hilltop 1478 1508 1.8 Prior to the issuance of building permits, school impact fees of $1.56 per square foot must be paid. $.69 is divided between the Elementary and Junior High Schools. E. Identification of Environmental Effects Biology Pacific Southwest Biological Services was retained to prepare a biological report of the site. The following discussion is a summary of the biological report. The biological report is included as ATTACHMENT B. Natural vegetation on-site consists of a vestigial of native shrubs including about a dozen Jojoba (Simmondsia chinensis); several Toyon IHeteromeles arbutifolia), Flat-Top Buckwheat (Erio~onum fasciculatum), Broom Baccharis (Baccharis sarothroides); and a lone Elderberry (Sambucus mexicana). Other native vegetation occurring on site consists of an assemblage of native weeds attracted to the residential water-runoff. The primary vegetation on the property consists of invasive, non-native grasses and non-native weedy species. The birds utilizing the area for foraging are typical of similar urban locales with numerous Mourning Doves, House Finches, Starlings, and Mockingbirds. Two common migrants were seen: Western Wood Peewee and the Hooded Oriole. The presence of reptile and mammal fauna is presumed to minimal, due to the isolation of the habitat and urban setting. Geology - As a result of concerns raised by neighbors, the applicant was required to provide the City with an evaluation of soil conditions. Dilks & Associates was contracted to prepare an investigation of soil suitability for residential construction. This report found that although large amounts of trash occurred within the top layers of soil material, all soils are suitable for reuse as compacted fill provided they can be adequately cleaned of trash and debris. The Preliminary Soils Investigation for: Chula Vista Tract No. 89-12 (Sun-Up Vista) is included as ATTACHMENT B. Groundwater - Neighbors also indicated that a naturally occurring spring was located on the project site. The "Preliminary Soils Report" investigated this possibility. The report states that "No groundwater was observed in test pits" and that "groundwater would not be expected to adversely affect the performance of the structures provided that it does not rise above the inundation elevation of 150 as shown on the Tentative Map" (See ATTACHMENT B). F. Mitigation necessary to avoid significant effects No mitigation is necessary to avoid significant impacts. G. Findings of Insignificant Impact The biologic component of the site is not unique and does not contain threatened or endangered species. Due to the sites isolation and location in an urban setting, its value as a wildlife habitat is minimal. Soils - Soils on the site are suitable for construction of the proposed project. Groundwater No groundwater was encountered on the proposed project site. Groundwater would not be expected to adversely affect the development of the site. H. Consultation 1.

Sincerely, Kate Shurson / Director of Planning KS:dp Sourest Biological SeruJces Post Office Box 985, National City, California 92050 (619) 477e5333 6 June 1989 Mr. Ken E. Green 3045 Rosecrans #205 San Diego, California 92107 PSBS #668 Dear Mr. Green: A biological survey of your 2.31 acre property on Telegraph Canyon Road east of Hilltop Drive revealed a heavily disturbed urban field habitat with no significant biological resources. The investigation was conducted by our biologist, Craig H. Reiser, on June 1, 1989. The vestigial native shrubs remaining on the site consist of approximately a dozen Jojoba (Simmondsia chinensis); several Toyon (Heteromeles arbutifolia), Flat-Top Buckwheat (Eriogonnm fasciculatum), Broom Baccharis (Baccharis sarothroides); and a lone Elderberry (Sambnctts mex'icana). Along the concrete llned channel which crosses the property from east to west is a meagre scattering of native weeds attracted to the residential water- runoff. In the shallow silt above the concrete grow Ragweed (Ambrosia psilostachya), one Willow Smartweed (Persicaria lapathifolinm), several Mexican Tea plants (Chenopodium ambrosioides), and a 1' by 5' swathe of Tule Cat-Tail (Typha domingensis) with its diagnostic narrow flowering stalks. No other native plants were found on site. The primary vegetation on the property consists of invasive, non-native elements with a predominance of Castor Bean (Ricilnts commtttds). Other conspicuous weeds include Giant Cane (Arttndo dottcLr), Wild Artichoke (Cynara cardunculus), Giant Sunflower (Helianthus annuus), Fennel (Foenicuhun vulgare), Peruvian Pepper (Schb~us molle), and Cocklebur (Xanthittm stnmtarium). Non-native grasses present are Wild Oat (Arena barbara), Rabbits-foot (Polypogon monspelicnsis) in the drainage channel, Italian Ryegrass (Lolium mttltiflotllm), Millet Ricegrass (Oryzopsis miliacea), and Red Bromc (Bromus rubens). The remaining, largely Eurasian, annual plants on thc site are Yellow Chrysanthemum (Chrysanthemnm coronarium), Australian Saltbush (Atriplex semibaccata), Wild Mustard (Brassica gcniculata), Wild Radish (Raphauus sativus), Horseweed (Conyza canadcnsis), Scarlet Pimpernel (,4nagallis arvcnsis), Bur Clover (Medicago polymorpha), Curly Dock (Rumer crispu$), Stinking Gourd (Cucurbita foetidissima), Wild Lettuce (Lactuca scrriola), Indian Sweet Clover (Mclilotus indicus), Cheesewced (Malva parviflora), and the ubiquitous Russian Thistle (Salsola attstralis). The birds utilizing the area for foraging are typical of similar urban locales with numerous Mourning Doves (Zenaida macrourct), a large flock of House Finches (Carpodacus m~ricatms), Starlings (Slltrluts vnlgat~s), and several Mockingbirds (Mimttspolyglottos) all sighted. Two common migrants were seen: a solitary Western Wood Peewee (Cotlloplls sordiduhts) and both a male and female Hooded Oriole ([ctetlts cuctdlallts). Given the isolation of thc habitat and urban setting, the reptile and mmnmal fauna is presumed to be minimal. House cats were noted roaming the small site and only the common House Mouse (3[its imtscnhts) and possibly the Norwegian Rat (Ratttts notvcgictts) are expected. In the cement channel thc Common Tree Frog (Hyla rcgilla) may be occasional. Mr. Ken Green 2 6 June 1989 PSBS #668 In summary, no sensitive plants or animals were seen, nor are any expected, on the property. Given the dearth of native resources, no biological recommendations are made for the proposed project which involves no significant, adverse biological impacts. Sincerely, R.

In general, we encountered loose topsoil over loose to dense natural soils; loose fill; and loose to moderately dense alluvial soils throughout the undeveloped area of the property. The loose fill mound that occurs on proposed Lots 4, 5 and 6 contained abundant amounts of trash; the majority of this available soil may not be salvageable due to the quantity of trash. It appears that the loose soils encountered in the other areas of the site reusable if properly prepared. are The accompanying report presents our work, field and' laboratory test results, and our recommendations for site preparation and earthwork, single-family residence foundation design, lateral earth pressures and preliminary pavement design. 89-094 SUN-UP VISTA PAGE 2 Mr. Ken Green Gold Key Development June 22, 1989 It has been our pleasure in providing these services to you.

B9-12 (SUN-UP VISTA) CHULA VISTA. CALIFORNIA PROJECT DESCRIPTION The projsct at Sun-Up Vista will consist of cut and fill earthwork in order to sight lots for single family hems prepare construction. An sxisting ninth lot was previously gradsd and built on in 1976. We understand that the undsvslopsd lsvsl pad area of this lot will be split off to provide the ninth lot for this subdivision. From information on the Tsntativs Map preparsd by Nasland Enginssring, it appears at this rims that maximum cuts of about 9 feet will occur at the southeast property corner and maximum fills of about 12 feet will occur at ths south end of tbs drivs at the east propsrty boundary. Cut and proposed access fill slopes are proposed at slope ratios of 2 to 1 and 1-1/2 to I, horizontal to vertical units. Maximum fill slope heights appear to be about 10 feet at a slope ratio of 1-1/2 to I and maximum cut slope heights appear to be about 5 feet at a slope ratio of 2 to 1. After grading, construction will consist of building nins, one or two story, concrete slab-on-grade, wood frame and stucco single family residences and appurtenant improvements, such as drives and retaining walls. Foundation loads are access anticipated to bs 2000 pounds-per-linsal foot or less for load bearing walls and tO kips or less for column loads. PURPOSE OF WORK The purpose of our work was to provide Mr. Ken Green and his designers with soil design recommendations for earthwork and site preparation, slope stability, building foundations, lateral earth prsssurss and prsliminary pavsmsnt dssign for privats streets. SCOPE OF WORK In order to accomplish our task, we performed a site 89-094 SUN-UP VISTA PAGE & reconnaissance, excavated and sampled three backhoe test pits, performed laboratory testing on selected soil samples, performed research for soils information pertinent to this site, performed engineering analysis, and prepared this report. Our work is for the express use of Mr. Ken Green and his designated consultants. This report pertains to and is valid only for Sun-Up Vista; we disclaim any obligation to provide, discuss or update this report for any other parties without Green's prior written authorization. Our services consist of opinions and recommendations rendered in a manner consistent with the level of care and skil! ordinarily exercised by members of the professions currently practicing under similar conditions and in the same locality,. This warranty is in lieu of all other warranties either express or implied. FIELD INVESTIGATION Our field investigation consisted of a site reconnaissance and excavating, logging and sampling three backhoe test pits at the approximate locations shown on Figure I, Site Plan. The backhoe test pits were excavated on June 9, 198g, with a Kubota KH-41 equipped with an 18-inch wide bucket. Disturbed soil samples were obtained at periodic intervals and returned to our laboratory for further examination and testing. Finalized boring logs are contained in the attached Appendix A, and laboratory test results are contained in the attached Appendix 8. The final boring logs represent our interpretation of the information contained on the field logs and on the laboratory test results. We can only infer that subsurface soil conditions in unexplored areas are similar to those found in the test pits. - CURRENT SITE CONDITIONS The project site is about a 2.3 acre group of undeveloped parcels located along the south side of Telegraph Canyon Road about 1000 feet east of Hilltop Drive in the City of Chula Vista, California. The property is bounded along the north by Telegraph Canyon Road, along the east by existing residential property of - Telegraph Knolls, Map No. 3665, along the south by residential property of Hobart Knolls, Maps 3170 and 3560, and on the west by 89-094 SUN-UP VISTA PAGE 7 a residential structure of Parcel 4 of Parcel Map 104. The majority of the site consists of loose fill dumped over loose alluvial soils. A flowing drainage channel bisects the eastern portion of the property and trends westerly along the rear of proposed Lots 5 through 9. Vegetation generally consists of heavy brush in the lower areas of the property and grass of the knoll at the southeast corner. A large pepper tree is present at approximately the northeast property corner. SOILS AND GEOLOGY The soils encountered at the site consist of silty to clayey sands with some clays present. Loose fill generally occurs to an elevation of about 144 feet, with alluvium and slopewash present below this elevation. The knoll and flatland in the vicinity of proposed Lots 1, 2 and 3 consists of naturally occurring topsoils over formational soils. Map Sheet 29, "Geology of National City, Imperial Beach and OLay Mesa Ouadrangles, Southern San Diego Metropolitan Area, California," published by the California Division of Mines and Geology, shows that the geologic units at the site are undifferentiated alluvium and slopewash in the lower areas and undifferentiated Bay Point Formation and unnamed, nearshore marine sandstone. The soils encountered in our test pits substantiate this geology. Map Sheet 29 shows that the property is approximately 800 feet west of the inferred west edge of the La Nacion Fault Zone. Our test pits did not reveal faulting or other geologic hazards on this property. No faults or landslides are known to exist on this site. The fault zones we consider to have the most potential as a source of damaging earthquakes that could affect the site are the Elsinore and San 3acinito Faults, located some 44 and 68 miles, respectively, north-northeast of the property We believe it is - reasonable to expect that the structures will be subjected to at least moderate earthquake shaking during their service life. The possibility of ground offset through the property during a seismic event is remote. SOIL CHARACTERISTICS Existing fill soil characteristics range from clays to 89-094 SUN-UP VISTA PAGE 8 silty, clayey sands. Our Test Pit 2 indicates that the loose fill mound in the vicinity of proposed Lots 4, 5 and 6 contains large quantities of trash and concrete debris. Trash consisted of paper, old pieces of rusted rebar and wire, pieces of garden hose and broken glass. Concrete debris encountered consisted of a 24"x15" thick chunk, old pieces of curbing, fence post footing with part of the metal post embedded, and 6 to 8 inch diameter pieces of 4 inch thick slab. The soils intermixed with the trash and debris would be suitable for reuse as compacted fill provided they could be adequately cleaned. The fills encountered in Test Pit 1 were generally free of trash and debris. Surface trash observed consisted of old tires and empty cans. We anticipate that surface trash will be removed during clearing and grubbing operations. The alluvial soils encountered consisted of silty to clayey sands, loose to about 4 feet below their top surfaces underneath the fill. The entire depth topsoils the upper 3 of of and about feet formational soils below the topsoils are reasonably dry and porous. All soils encountered are suitable for reuse as compacted fill provided they can be adequately cleaned of trash and debris. Laboratory testing at this time indicates that the soils will range From non to moderately expansive (0 to & percent swell); the expansivity of the soils may change due to the mixing effect excavation and recompaction will have. GROUNDWATER The concrete lined drainage channel traversing east to west across the site contained flowing water approximately 2 inches deep during our field work. The unlined channel traversing northerly along the west edge of proposed Lots 2 and 3 was dry at the time of our field work, however, we suspect flow to occur during the rainy season. No groundwater was observed in our test pits at the time of excavation; however, the upper zone of alluvial soil encountered in Test Pit 2 had a fairly high moisture content. Wet soil conditions or groundwater may be encountered at the deeper excavations along the channel during grading; however, we do not believe that groundwater wil! adversely affect the performance of the structures provided it does not rise above the inundation 89-094 SUN-UP VISTA PAGE 9 elevation of 150 feet as shown on the Tentative Map. We did not note seepage in the existing slopes along the southern boundary of the property nor along the lower portions of the knoll in the southeast portion of the property. It is our opinion that naturally occurring seepage will not be a problem at this project. CONCLUSIONS Based on our field explorations, evaluation of the laboratory test results, engineering analysis, and on our general experience in the soil engineering field, it is our opinion that the site is suitable for construction of the proposed project provided the recommendations that follow are incorporated into the design of the project and implemented during construction. RECOHNENDATIONS A. SITE PREPARATION AND EARTHWORK 1. Q!~Kiog_~D¢_~Ki~iDg: All existing vegetation within the limits of grading should be removed in their entirety prior to earthwork. All cleared and stripped vegetation and debris must be disposed of off the property at a legal dump site. a. Eil!: All loose fill should be excavated and cleaned of all trash and debris prior to reuse as properly compacted fill. The general extent of loose fill appears to extend from the concrete lined channel northerly to Telegraph Canyon Road and appears to occur down to an elevation of about 144 feet. We believe that it is prudent to anticipate locally deeper areas and areas of higher debris concentration than those encountered in our test pits. b. ~!!uYia!__5~i!~: The alluvial soils encountered be]ow the fill are generally loose within the upper 2 to 3 feet, and are not suitable in their present condition to adequately support additional fill or structure loads without detrimental settlements. We recommend that these soils be excavated, appropriately moisturized, and be replaced as properly compacted fill prior to adding new fill. c. The 89-094 SUN-UP VISTA PAGE lO topsoil and upper 2 to 3 feet of natural soil below the topsoil are generally dry and porous, making them unsuitable for building loads or additional fill in their present condition. We recommend that in areas where planned' cuts will be less than 5 feet deep, the remaining soils to a depth of at least 5 feet below original ground surface be overexcavated, appropriately moisturized, and replaced as properly compacted fill. Likewise, planned fill areas should be overexoavated to a depth of 5 feet below original ground surface, appropriately moisturized, and replaced as properly compacted fill prior to placing additional fill or structures. The surfaces of all approved undercut or overexcavated areas should be scarified to a depth of 8 inches, appropriately moisturized, and properly compacted prior to refilling. 3. ~lG!~!iSD: It is our opinion that the required excavations may be accomplished using conventional excavating equipment. All excavation work should be performed by an experienced excavating contractor. 4. U~Ei~!~__£g~__E!!!: It is our opinion that all existing soils present on the property re- will be suitable for use as compacted fill provided the trash and debris can be adequately cleaned from the existing fills. Existing on-site soils used as fill should not contain rocks, hard lumps or rigid pieces larger than 4 inches in maximum dimension and should not contain more than 15 percent, by weight, of material larger than 2-1/2 inches. No organic or biodegradable material should be incorporated in the fill. Imported fill material should be a non-expansive granular index of 15 or less and should meet the soil with plasticity a size and cleanliness requirements given in the previous paragraph. 5. U~i~!~___~9~___~i!!: Soils generated from excavations are suitable for use as backfill material when properly compacted, provided they meet the size and cleanliness requirements as specified in Item 4. 6. Com~i~D: It is our opinion that all fill and backfill should be compacted to a minimum degree of compaction (relative compaction) of at least 92 percent of that soils' maximum dry density as determined in accordance with ASTM Standard Test Method D1557-78. All fill and backfill soils should be spread and properly compacted in lift thicknesses appropriate to the type of compaction equipment used. All soil used as fill or backfill must be brought to a uniform moisture content ranging between optimum moisture content (OMC) and OMC + 3% prior to compaction. 89-094 SUN-UP VISTA PAGE 11 7. Q~i!i~Z__I~oGb~: It is our opinion that all utility trenches should be excavated with a minimum fal] of 1/4 inch-per- foot away from the structures for a minimum distance of 5 feet outside the building footprint to help reduce the potential for water to pond in low areas of the trenches below the home or near foundations. Utility trench backfill should be placed and compacted in lift thicknesses appropriate to the type of compaction equipment used and should be compacted to a minimum relative compaction of 92 percent at OMC. 8. Q~io~g~: Finish grade surfaces adjacent to foundations and surface improvements should have positive gradients on the order of 5 percent, plus or minus 2 percent, away from the structures to help reduce the potential for ponding to occur adjacent to foundations and other improvements. Raingutters and downspouts should be installed on all structures to help control roof runoff. Downdrain outlets should be equipped to discharge flow at least 5 feet away from foundations. Yard surface gradients should be maintained to help collect runoff and channel it to City approved drainage facilities. No free drainage should be directed over the tops of slopes. B. SLOPE STABILITY 1. I~eQSaSZ__Q~D~!~U~[iQD_~!ge~: Construction cut slopes in existing loose fill and alluvial soils should not be steeper than 1/2 to 1 (Horizontal to vertical) and should not exceed 12 feet in vertical height. Construction cuts in the natural ground in the southeast portion of the site for retaining wall cuts may be vertical up to heights of ~0 feet. Some localized sloughing or ravelling may occur on the exposed slope faces. The stability of temporary construction slopes will also depend heavily on equipment loadings and materials storage along the tops of the slopes. In general, no loads should be allowed at the top of temporary slopes within a horizontal distance equal to the vertical depth of cut. 2. E~E~B~D[_-~!Q~¢~: We have performed slope stability analysis for the proposed cut and fill slopes by the 3anbu method using the following parameters: Phi angle of 25 degrees; cohesion intercept of 200 psf; and in-place tota] soil density of 125 pcf. The results of those analysis indicate that the proposed slopes have calculated factors of safety in excess of 1.5 for static conditions at slope ratios of both 1-1/2 and 2 to I for vertical heights of up to 12 feet. Stability analysis require using parameters selected from a range of possible values. There is a 89-094 SUN-UP VISTA PAGE finite possibility that slopes having calculated factors of safety, as indicated, could become unstable. In our opinion, the probability of slopes becoming unstable is very low provided the status-quo of the slopes remain unchanged after construction. Fill slopes, especially those constructed at inclinations steeper than 2 to t, are particularly susceptible to shallow slope sloughing in periods of rainfall, heavy irrigation, or overirrigation, and upslope surface runoff. Periodic slope maintenance may be required, including rebuilding the outer 4 feet or so of slope surface. The potential for sloughing of fill slopes can be reduced by overbuilding the slopes at least 4 feet and back the desired face. To lesser cutting to slope a degree, the potential for sloughing can be reduced by backrolling the slope faces at 3 to 4 foot intervals. C. FOUNDATIONS At this time, it appears that the foundation bearing soils to moderately expansive soils (6 · swell). may range up therefore, the foundation recommendation that follow are based on 6 · expansive soil. 1. QQUW~O~igD~!___EgQ%iD9~: An allowable soil bearing pressure of 2000 pounds-per-square foot (psf) may be used in the design of conventional, continuous strip footings at least 12 inches wide founded at least 18 inches below level pad grade for single or two-story structures placed on properly compacted fill or competent natural ground. All strip footings should be continuously reinforced with two number 5 reinforcing bars (5/8 inch diameter), one placed 3 inches up from the bottom of the footing and the second placed 12 inches above the lower bar. 2. ~E~Q__EQg~iDg~: An allowable soil bearing pressure of 2000 psf may be used in the design of spread footings at least 18 inches square founded a minimum of 18 inches below level pad grade. Spread footings should contain a reinforcing mat of two number 5 bars each way placed 3 inches above the bottom of the footing in both directions. pressure of 3000 psf may be used in the design of retaining wall footings founded a minimum of 24 inches below lowest adjacent grade in competent natural soil or properly compacted fill. Footing widths and reinforcing steel should be in accordance with the structural engineers design specifications. The allowable soil bearing pressures given are for combined dead plus live load and may be increased by one-third to 89-094 SUN-UP VISTA PAGE 13 accommodate transient forces from wind and seismic loads. The reinforcing specified is to help protect against moderately expansive soils and to help span local irregularities, and is not in lieu of what may be required by the project structural engineer. No bearing foundation should be located closer than 10 feet From the top of slopes measured horizontally from the slope side of the foundation at the bearing level (10 feet to daylite). 4. ~!~zQDz~9~: Concrete floor slabs-on-grade should be designed in accordance with the anticipated use and loading of the slab. As a minimum, we recommend that floor slabs be a minimum of 4 inches thick, net, and be nominally reinforced with a steel area ratio of 0.0014. The slab steel should be maintained at the slab midheight. All slab-on-grade floors should be placed on a 4 inch thick clean sand bedding that is in turn underlain by a 10 mil thick visqueen moisture barrier. The appropriate active case equivalent fluid pressure I acting retaining walls be selected from the on may fol loNing table: I BACKSLOPE ACTIVE PRESSURE ~ 1-1/2 to 1 85 2 to 1 60 J Level 45 The above table is for unrestrained, unsurcharged wall J_ conditions only. A passive case equivalent fluid pressure of 250 pcf in j conjunction with a concrete-to-soil coefficient of friction of 0.25 may be used in lateral load resistance design. ~ minimum of 10 feet of soil must occur horizontally on the passive side in order to develop full passive resistance. We recommend that the Foot be ignored in calculating passive resistance. top D. PRELIMINARY PAVEMENT DESIGN Based on an estimated R-value of 20 for the on-site soils and a minimum R-value o¢ &O for' class III decomposed granite base material, the private driveways at the site should be 3-1/2 89-094 SUN-UP VISTA PAGE 14 inches of asphalt paving over & inches of compacted base. The top 12 inches of subgrade should be compacted to a minimum relative compaction of 95 percent prior to placing base. Likewise, base material should be compacted to a minimum of 95 percent relative compaction prior to placing asphalt paving. Me suggest that R-value testing be performed on the actual pavement subgrade soils when they become apparent. Revisions in base and pavement thickness can be made at that time. E. ADDITIONAL ~ORK It is our opinion that the following additional work be performed during the remaining design phase and during the construction phase of this project. This additional work is not part of the original scope of this soil investigation and will incur additional expense on a time-and-materials basis. The client should budget their costs accordingly. It is opinion that the 1. our foundation plans be reviewed to verify conformance to the recommendations of this report. that an experienced sol] engineering firm continuously observe the site preparation and earthwork operations at the site. 3. Com~Q~lQD_Z~[iDg: We recommend that all fill and backfill deeper than 12 inches be placed and compacted under the of experienced soil engineering firm and that observation an compaction tests be performed to verify conformance with the recommendations of this report and the City of Chula Mista grading ordinance. 4. Foo~iDg__!DeB~GkiQD: It is our opinion that all footing excavations be examined by an experienced soil engineering firm to verify conformance to the plans and specifications and to check for adverse soil conditions. 5. EiDa!_B~BeE~iDg: It is our opinion that a final as-built report be prepared and issued that presents the results of inspections and compaction testing. UNCERTAINITY AND LIMITATIONS Our opinions and recommendations are based on information 89-094 SUN-UP UISTA PAGE 15 obtained from the field reconnaissance, test pits, laboratory test results, engineering analysis and on our experience in the geotechnical field. The recommendations presented are based on the assumption that the overall soil conditions will not be substantially different from those found during our field investigation. If variations or adverse soil conditions are encountered during construction, or if the proposed construction differs from that presently planned, the soils engineering firm must be consulted for further recommendations. California, including San Diego County, is an area of high seismic risk. It is generally considered economically unfeasible to build a totally earthquake-resistent project; it is therefore reasonable to expect that a large or nearby earthquake can cause damage at the site. Soil inspection services allow observation and testing of only a very small percentage of work performed at a site. Contractual arrangements with the respective contractors should contain the provisions that they are responsible for performing all soils-related work in accordance with the project specifications. Inspection by the geotechnical engineer during and construction does not relieve the respective site preparation contractors of their primary responsibility to perform all work in accordance with the contract specifications. A copy of this report should be made a part of the project specifications and contract documents. 89-094 SUN-UP VISTA PAGE CITY OF CHULA VISTA DISCLOSURE STATEMENT IAPPLICANT'S STATEMENT OF DISCLOSURE OF CERTAIN OWNERSHIP INTERESTS ON ALL APPLICATIONS WHICH WILL REQUIRE DISCRETIONARY ACTION ON THE PART OF THE CITY COUNCIL, PLANNING COMMISSION AND ALL OTHER OFFICIAL BODIES.

EIR Mitigation Measures - Planning 1. Regarding soils and geology, most of the required excavations can be made by conventional heavy grading equipment; however, some ripping of cemented beds may be needed. The geotechnical report identifies detailed grading and earthwork recommendations. The geotechnical consultant shall monitor grading to confirm that field conditions are consistent with the conditions predicted by the preliminary investigations. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 8 2. Regarding biology, impacts to wildlife and plant communities are partially mitigated through the preservation of open space within the SPA II area, reve§etation of cut and fill slopes and revegetation of sewer main disturbances. Impacts to the black tail gnat catcher are significant and unmitigated. Impacts to cactus wren would be mitigated through retention of two-thirds of the population and open space. Specific measures shall be taken to mitigate impacts to the cactus wren li.e., transplanting coast cholla) and the San Diego thorn mint population (i.e., fence preservation area). 3. Regarding archeology, the loss of W-3432 shall be mitigated through the implementation of a compensatory mitigation program. This will involve additional field study and research on sites in the project area; primarily additional sampling of a site within SPA III, SDi-960/961 as appropriate, supplemented by a research project that would focus upon the archeological resources within a two mile radius of the project. The results of this research shall be submitted to the City of Chula Vista, the San Diego State University Clearing House and the Museum of Man. 4. Existing roadway conditions in the project area which include segments of Otay Lakes Road and East "H" Street are inadequate and future traffic increases associated with the project will require modifications to the circulation system in the study area. The recommended mitigation measures shall be phased and based on the amount of construction completed on the project. All streets internal to the project shall be designed according to the classifications provided in the project description and will meet City standards. Mitigation measures have been tied to coordinate with phased development as follows: Mitigations: Commercial - 0 acres Industrial - 0 acres Residential - 0 DUs ° The segment of Otay Lakes Road between Camino del Cerro Grande and Ridgeback Road shall be widened to 4 lanes (currently being constructed). ° East "H" Street between the 1-805 northbound off-ramp and Hidden Vista Road shall be restriped for 3 eastbound lanes. ° The East "H" Street/I-805 southbound, on/off ramps intersection shall be signalized. The existing southbound 1-805 to eastbound East "H" Street loop ramp shall be reconfigured to pass through the signalized intersection with dual right turn lanes. The eastbound approach to this intersection shall be reconfigured to provide 3 lanes. These improvements to the 1-805/East "H" Street interchange should alleviate forecasted traffic impacts at the interchange through 1991. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 9 Mitigations: Commercial - .82 acres Industrial - 4.76 acres Residential - 0 DUs ° No improvements recommended. Mitigations: Commercial - {.82 + 1.66 = 2.48 acres) Industrial (4.76 + 9.52 : 14.28 acres) Residential - {0 + 952 DUs) ° The following intersections with East "H" Street shall be signalized: Road B, East Business Park Road, and Road C {Paseo Ranchero). ° If the East "H" Street/Buena Vista Way intersection is not signalized prior to this year, it will be done at this time. Mitigations: Commercial - {2.48 + 1.66 = 4.14 acres) Industrial - (14.28 + 9.52 = 23.8 acres) Residential - (952 + 619 = 1,571 DUs) ° The intersection of East "H" Street/Ridgeback Road shall be signalized. ° The intersection of Otay Lakes Road/Road A (Avenida Del Rey) shall be signalized. Mitigation: Commercial - {4.14 + 1.66 : 5.8 acres) Industrial - (23.8 + 9.52 = 33.32 acres) Residential - {1,571 + 320 = 1,891 DUs) ° The eastbound approach to the East "H" Street/I-805 northbound off-ramp intersection shall be reconfigured to provide 3 through lanes. East "H" Street shall be widened from 3 to 4 lanes between the 1-805 northbound off-ramp and the westerly Terra Nova Plaza driveway. A right turn acceleration lane for vehicles exiting the westerly Terra Nova Plaza driveway shall be provided. ° Reconfigure the East "H" Street/I-805 southbound on/off-ramp intersection to provide dual left turns for the westbound approach. Mitigation: Commercial - (5.8 + .82 = 6.62 acres) Industrial - (33.32 + 1.15 = 34.47 acres) Residential - (1,891 + 487 = 2,378 DUs) ° No improvements recommended. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page l0 Mitigation: Commercial - (6.62 + 0 = 6.62 acres) Industrial - (34.47 + 2.38 : 36.85 acres) Residential - (2,378 + 140 = 2,518 DUs) ° No improvements recommended. 5. Monitoring/Reportin9 Program City staff shall ensure that the recommendations contained in the Transportation section of the SEIR regarding road modifications are incorporated into the tentative map. 6. Analysis of Significance Assuming several road widening actions and intersection geometry changes were completed as outlined in the Mitigation Measures section, then no significant impacts to circulation would occur. 7. Development of on-site water facilities shall be provided as outlined in the OWD Master Plan Update to provide adequate infrastructure to water distribution. To ensure year round water supply, the applicant shall be required to work with OWD to increase water storage facilities. 8. In compliance with the threshold standards, the City shall review the projected sewage flows and volumes for compliance with City engineering standards. 9. The impacts associated with the existing 69 KV line shall be mitigated by relocation and partial undergrounding. C. DISCUSSION General Lottin9 of the Area The Rancho del Rey SPA II area comprises 567 dwelling units on 376 acres. Within that area there is a five acre neighborhood park, 168 acres of open space and a six acre community facility site which is proposed for use as a day care facility and church site. The residential lotting pattern is broken down as follows: 1. Estate Lots - The estate lots are located generally north of Rancho del Rey Parkway. There are 211 lots in this category with 63 lots under 12,000 sq. ft., 113 between 12,000 and 18,000 sq. ft., and 35 lots larger than 18,000 sq. ft. The averages by subarea are as follows: City Planning Commission Agenda Items for Meeting of September 13, 1989 Page ll ° R-la : 14,400 sq. ft. with a pad size of 9,600 sq. ft. ° R-lb = 18,200 sq. ft. with a pad size of 12,000 sq. ft. ° R-lc : 14,400 sq. ft. with a pad size of 9,600 sq. ft. 2. Conventional Lots - The conventional lots are located south of Rancho del Rey Parkway and represent a continuation of the lot pattern in SPA I. The conventional lots start 5,000 sq. ft. with the predominant lot size over 7,000 sq. ft. Out of the 356 conventional lots, approximately 125 are under 7,000 sq. ft. leaving 231 in excess of 7,000 sq. ft. The average lot size by subarea are as follows: ° R-2a : lO,O00 sq. ft. with a pad size of 7,000 sq. ft. ° R-2b = 8,600 sq. ft. with a pad size of 6,000 sq. ft. ° R-2c : 7,000 sq. ft. with a pad size of 5,000 sq. ft. 3. Community Facilities - The community facility lots {Lots 413 and 414) are located on the south side of Rancho del Rey Parkway at the intersection of Ridgeback Road. There are two lots within the six acre area and the purpose of these lots is to create sites for a daycare center, which would be located at the southwesterly portion of this territory, and a church site. The actual uses are regulated by the PC development regulations and only include community serving uses. Development of this site will be determined during the site plan approval process. 4. Parks and Recreation - There is a five acre neighborhood park {Lot Q) located on the south side of Rancho del Rey Parkway between subareas R-2a and R-2b. This park will be connected by the trail system which extends from the Community of Bonita to the Rice Canyon trail system. The design and development of this park will be reviewed and approved by the Director of Parks and Recreation and the City Council. 5. Open Space - The open space lots within SPA II represent approximately 168 acres. Of the 168 acres that are open space, approximately 40 acres will be graded. The open space area is evenly divided between the estate and conventional lots and generally includes naturally steep topography sloping either towards Rice Canyon or towards the Community of Bonita. Also included in open space is the thorn mint preserve area (Lot "M" - 40.7 acres) located north of Rancho del Rey Parkway between areas R-lb and R-lc. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 12 Phasing The Rancho del Rey subdivision is divided into two phases with various units provided within each phase. Phase 1 includes both conventional and estate housing and is the furthest easterly portion of the subdivision. It will generally be an extension of SPA I. Phase 2 includes both estate and conventional units as well as the five acre neighborhood park and the six acre community facility site. Phase 2 would close the loop of Rancho del Rey Parkway and provide access through Rid§eback Road. The phases are also governed by the SPA II Public Facilities Plan and there are several conditions in this report that control the issuance of permits and the provision of facilities by phase. Street Names The applicant has submitted a list of street names which is being reviewed by the various City departments. Final approval of the street names is required by the Planning Commission; therefore, the names will be resubmitted at a later date for your consideration. Low and Moderate Income Housing The housing element of the Chula Vista General Plan requires that each project over 50 units in size provide at least 10% of the total dwelling units for low and moderate income families. A condition was placed on the Rancho del Rey SPA II plan that the subdivision map contain a condition requiring compliance with that requirement. Because this condition is being placed in the middle of implementation of the overall E1 Rancho del Rey Specific Plan, the condition which is contained in the subdivision map (Condition #5 Planning) refers to the entire specific plan and permits compliance with that housing requirement taking into consideration possible past implementation. The details of the Rancho del Rey program regarding location of affordable units, qualification of buyers, maximum housing costs, and monitoring will be formalized in a program approved by the City Housing Coordinator prior to recordation of the Final Map. Circulation and Street Improvements Approval of this subdivision involves a variety of on-site and off-site street improvements. The on-site street improvements are listed in the conditions of approval. These streets are consistent with the circulation element of the General Plan and conform to the City standards for streets. The off-site street improvements are documented in the Rancho del Rey SPA II Public Facilities Plan and Financing Analysis and are tied to phases of development. The Public Facilities Plan and Financing Analysis also includes the phased implementation of on-site improvements. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 13 Other Required Facilities and Fees This map also provides sites for a park and a community facility complex. Provisions have been made within the Rancho del Rey SPA II Public Facilities Plan and Financing Analysis to tie this subdivision map to SPA I and the improvements and facilities required both on- and off-site to solve certain Citywide facility deficiencies. SPA I includes sites for a fire station and fire training facility, a library, an elementary school, and a community park. The Rancho del Rey public facilities plan provides either for improvement of those facilities or in-lieu fees commensurate with the need generated by these projects. Design Guidelines The design guidelines for SPA II include standards and criteria for community features such as circulation, grading, entries, fencing, and improved edges with the canyon interface and community facility/park interfaces. It also includes general development guidelines for architecture, signing, lighting, and parking. The majority of the design guidelines encompasses landscape design. Landscape zones are proposed which promote drought tolerant/naturalized landscaping as the predominant landscape theme. Other features of the landscape design program include slope erosion control, natural open space enhancement, irrigation standards, fuel modification landscaping and streetscape landscaping. The revised design guidelines have been included in the Planning Commission review packet and would replace those presently in your SPA II binder. D. FINDINGS 1. Pursuant to Section 66473.5 of the Subdivision Map Act, tentative subdivision map for Rancho del Rey SPA II, Tract 89-5 is found to be consistent with the Chula Vista General Plan as adopted by the Chula Vista City Council based on the following findings. a. Land Use Element The E1 Rancho del Rey Specific Plan designates this area for estate and conventional housing as depicted in the subdivision map. The unit totals, the type of housing, and the open space system are consistent with the E1 Rancho del Rey Specific Plan and, therefore, consistent with the Chula Vista General Plan. b. Circulation Element All of the on-site and off-site public streets required to serve the subdivision are consistent with the circulation element of Chula Vista General Plan and the circulation proposed within the E1 Rancho del Rey Specific Plan. Those facilities will either be constructed or in-lieu fees paid in accordance with the Rancho del Rey SPA II Public Facilities Plan and Financing Analysis. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 14 c. Housing Element A low and moderate income housing program with an established goal of 5% low and 5% moderate will be implemented subject to the approval of the City's Housing Coordinator. Computation of the satisfaction of this condition will include the entire E1 Rancho del Rey Specific Planning Area. d. Parks and Recreation Element The subdivision will provide a five acre neighborhood park site in accordance with the E1 Rancho del Rey Specific Plan. In addition to that, this park will be connected by a series of trails that will connect the existing Bonita equestrian trail system to the Rice Canyon trail system. e. Public Facilities Element This project is obligated in the conditions of approval to provide all on-site and off-site facilities necessary to serve this project. In addition to that, there are other regional facilities which this project {together with SPA-I) is contributing to including a public library site, fire station site, and fire training facility site. The subdivision is also contributing to the Otay Water District's improvement requirements to provide terminal water storage for this project as well as other major projects in the eastern territories. f. Open Space and Conservation Element The proposed subdivision is in conformance with the goals and policies of this element. The open space and significant plant or animal resources that were identified in the E1 Rancho del Rey Specific Plan and refined in the EIR for Rancho del Rey SPA II are proposed either for preservation or mitigation consistent with that environmental impact report. OUt of the 376 acres within SPA II, 168 acres (or 44.6%) remain as open space and only 40 acres of that will be graded. g. Safety Element The project site is considered a seismically active area, although there are no known active faults on or adjacent to the property. Fire protection facilities and services needed to serve the project have been reviewed by the Fire Department. Other emergency service agencies have reviewed the project subdivision for conformance with safety policy. The project will increase the need for additional police and fire personnel, however, the City is planning to meet that need with additional revenues provided by this project. A fire station is proposed within Rancho del Rey SPA-I. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 15 h. Noise Element Noise mitigation measures included in the environmental impact report adequately address noise policy of the General Plan. All dwelling units within the project will be required to be designed so as not to exceed the interior noise level of 45 dBA. Additionally all exterior private open space will be shielded by a combination of earth, berm, wall, and/or buildings to achieve a 65 dBA noise level for outside private areas. W?C 6693P MONffORING/REPORTING PROGRAM RANCHO DEL REY SECTIONAL PLANNING AREA (SPA) II PLAN SCH ~88100~21 Prepared for: The City of Chula Vista Environmental Review Coordinator 276 Fourth Avenue Chula Vista, CA 92010 Prepared by: P&D Technologies, Inc. t~01 West "A' Street Suite 2500 San Diego, CA 92101 (619) 232-~t~66 3uly 1989 INTRODUCTION Recent California legislation (AB 3180) requires the adoption of a mitigation or reporting program in conjunction with approval of projects for which a Negative Declaration or Final Environmental Impact Report (EIR) was prepared and mitigation measures were recommended in connection with significant impacts. The purpose of the law is to establish a reporting or monitoring program to assure implementation of recommended mitigation measures. The following monitoring program is recommended as part of the Supplemental EIR (SEIR) which addresses the proposed Rancho del Rey Sectional Planning Area (SPA) II project. The EIR discusses the development of approximately 3?0 acres located within the El Rancho del Rey Specific Plan area. The plan includes residential development) community facilities and park and open space uses located northeast of the intersection of East H Street and Ridgeback Road, and the extension of an existing borrow site which is located along the eastern edge of SPA II in the vincinity of Rancho Del Rey Parkway. The Rancho del Rey SPA II Plan proposes the construction of 56? single-family dwelling units (DU) of low to medium density (i.e., 208 DU at 0-2 dwelling units/acres (DU/ac) and 359 DU at 2-# DU/ac) on approximately 192 acres. SPA II also includes a community facilities site (6.1 acres); neighborhood park (6.5 acres); four open space areas (total 158.3 acres)~ and major circulation routes (12.9) acres. Implementation of SPA II would not require any residential density transfers or rezone. The approval of SPA II will include the SPA II Plans a tentative map~ a Public Facilities Financing Plan, Design Guidelines and a Development Agreement. The following text is divided into eleven issue areas analyzed in the EIR. Each issue contains four sections. Section A describes the potential impacts associated with implementation of the project. Section B lists the mitigation measures recommended to reduce potential impacts. Section C is the monitoring/reporting program and Section D presents an analysis of significance for each issue area after mitigation. -1- SOIL5 AND ¢~OLOGY A. Potential Impacts Development o! the proposed project wood involve mass grading of ridge- tops and filling of canyons and side slopes. The Otay Formation is expected to be the primary unit exposed ~(ter grading. Although traces of the La Nation Fault cross the western portion of the site, they are not considered active. B. Mitigation Measures Mo~t of the required excavations can be made by conventional heavy grading equipment) however, some ripping of cemented beds may he needed. The geotechnicai report identifies detailed grading and earthwork recommen- dations. The geotechnlcai consultant wood monitor grading to confirm that field conditions are consistent with the ~onditions predicted by the pre- iiminar y investigations. C. Monitoring/Reporting Program City Engineering staff wood ensure that the recommendations contained in the geotechnicai investigation report are incorporated as conditions on the Tentative Maps~ Final Maps, and project grading plans. It is the responsibility of the soils engineer to visit the site during grading to assure that grading operations conform to the geotechnicai recommendations contained in the report and that field conditions are consistent with the conditions predicted by the preliminary investigations. A letter of authorization for the geotech- nical review must be submitted prior to grading plan approval. D. Analysis of Significance Gompressible alluvium, colluvium and expansive bentonitic soils are unsatis- factory for development without remedial treatment. This is regarded as a significant~ mitigable impact. Traces of the La Nacion Fault zone cross or underlie the site~ surface fault rupture and ground shaking have been identified as remote but potentially significant impacts. -2- DRA INA (~/GROUND WATE R/WATER QUALIFY A. Potential Impacts The proposed project would result in additional impervious surface area which would increase surface water runoff rates. Development of the site would result in a change in the type and amount of contaminants contained in surface runoff. This represents a cumulative impact to local water quality. B. Mitigation Measures On-site improvements, induding natural and improved channels with dosed conduit~ would mitigate drainage impacts. No mitigation is proposed for potential water quality impacts since flows would not drain into a domestic water supply. C. Monitoring]Reporting Program City Engineering staff would ensure that recommended erosion control measures are incorporated as conditions on the Tentative Maps, Final Maps and project grading plans. 13uilding permit issuance must be conditioned on the incorporation of these mitigation measures into the tentative map and final map. D. Analysis of 5il~nificance Adequate on-site drainage facilities and improvements will be developed in conjunction with the project, and no significant impacts are anticipated. Storm water flows and volumes would not exceed City Engineering standards and are in conformance with the Threshold standard. LANDFOR M/AESTI~TIC~ A. Potential Impacts Development of SPA II would significantly alter landforms on-site. Grading would be primarily confined to the ridge-top areas, with the major canyon -3- areas retained as open space. The degree of visual alteration is consistent with what was anticipated when the spedfic plan was approved. B. Mit1 ~ation Meascres Grading associated with the project would be in conformance with the general grading slope bank standards set forth in the SPA 11 Plan. Implemen- tation of the comm~ity design guidelines would reduce impacts to below a level of slgrfificance. They indude landscaping, fendng design, community signing, lighting and parking design/street furnit~'e. C. Monitoring/ Reportinl~ Program Ali grading plans will be reviewed by City staff to assure consistency with the recommendations listed below: o Visual significant slope banks would be preserved in their natural state by clustering development. o The natural character of the hillside would be retained where practical. o A variety of housing, padding techniques, grading techniques, lot sizes, site design, density, arrangement, and spacing of homes and develop- merits would be required. o Innovative architectural, landscaping, circulation, and site design would be required. o Safety against unstable slopes or slopes subiect to erosion and deterio- ration would be provided. Final approval must be granted by the City Coundl. Construction permits will be issued only after completion o! the design review and approval by City staff and the City CounCil. The recommendations regarding grading would be incorporated and verified in the design review stage. D. Analysis of Significance While the SPA II Plan is consistent with the adopted specific plan in terms of landform and visual character~ the project would result in significant visual impacts. The visual impacts associated with the cut and fill slopes would be mitigated by adherence to the SPA II design guidelines. Implementation of these guidelines in the construction of the project would reduce visual impacts to below a level of significance. BIOI. OGY Potential Impacts Development of the proposed project would result in a potentially significant loss of sensitive spedes. Impacts to the cactus wren would be adverse but not significant because approximately two-thirds of the cactus wren popu- lation is preserved in open space. Development df the project would result in significant impacts to the black-tailed gnatcatcher. The project design has been modified to preserve the San Diego thornmint site. There would be no impacts to the snake cholla transplant area in Rice Canyon. B. Mitigation Measures Impacts to wildlife and plant communities are partially mitigated through the preservation of open space within the SPA II area, revegetation of cut and fill slopes and revegetation of sewer main disturbances. Impacts to the black- tailed gnatcatcher are significant and unmitigated. Impacts to the cactus wren would be mitigated through retention of two-thirds of the population in open space. Specific measures would be taken to mitigate impacts to the cactus wren (ia., transplanting coast cholla) and the San Diego thornmint population (i.e., fenced preservation area). C. Monitoring/Reporting Program Building permit issuance must be conditioned on the incorporation of recom- mended mitigation measures into project design plans. -5- o Prior to the initiation of on=site grading activities) a qualified biologist would clearly define the buffer habitat to be avoided during grading. A meeting would also take place between a representative of City staff, the grading contractor and the biologist to clarify the areas to be avoided during grading and review methods to reduce on-site grading impacts. Periodic inspection wood occur to ensure that construction activities do not affect vegetation within the marked area. The City staff representative and/or biologist would have the power to halt grading operations if there is evidence that these operations have not stayed within designated boundaries. o ^ City staff representative and/or biologist wood ensure through periodic inspection, that the fenced thornmint preservation area remains intact and that any damage to the fence is quickly repaired. o A qualified biologist would be retained to implement the revegetation of cut and fill slopes, sewer main disturbances and the transplanting of coast cholla to mitigate impacts to cactus wren. The revegetation program and transplanting wood be monitored periodically to ensure satisfactory replacement of disturbed habitat. Should it be identified at any time that the mitigation is failing, a review will be conducted to determine cause and resolution proposed {replanting or another site selected). ^ written status report wood be submitted annually for three years. ^ detailed monitoring schedule (quarterly for the first year, and annually for the following two years) must be adopted as part of the revegetation and transplanting program. The revegetation and trans- planting plan must he approved as a condition of the tentative map. D. Ami)sis of $il~ificance Implementation of the proposed proiect wood result in a significant un- mitigated impact to the black-tailed gnatcatcher. Impacts to the cactus wren and the San Diego thornmint would be adverse, but reduced to below a level of significance through adherence to recommended mitigation -6- ARCHAEOLOGY A. Potential Impacts Field investigations at the archaeological site V/-3~32 demonstrated that the site has been destroyed by grading for a water pipeline setup for water transport to the development project in SPA L Due to the disturbance~ an evaluation of significance as required by CEQA cannot be performed due to the elimination of cultural materials. Because there is no means to prove that the site was insignificant~ it is assumed that the site was significant. B. Mitigation Measures The loss of W-3#32 would be mitigated through the implementation of a compensatory mitigation program. This will involve additional field study and research on sites in the project areal primarily additional sampling of a site within SPA III, SDi-960/961 as appropriate, supplemented by a research project that would focus upon the archaeological resources within a two-mile radius of the project. The results of this research would be submitted to the City of Chula Vista, the San Diego State University Clearinghouse and the Museum of Man. C. Monitoring/Reporting Program Building permit issuance would be conditioned upon implementation of the recommended mitigation program by a qualified archaeologist. City staff would ensure prior to building permit issuance, that the compensatory mitigation program for site SDi-960/961 with SPA III has been implemented and that the results from the testing and evaluation are submitted to the City of Chula Vista, the San Diego State University Clearinghouse and the Museum of Man. -7- D. Anat)'sis of SiRnificance The impacts which have occurred to Site W-3432 would be mitigated to below a level of significance through implementation of the compensatory miti- gation program for a cultural resource site within SPA III. The applicant has agreed to this mitigation measure and a condition will be placed on the tentative map. TitAN SPORTATION/ACCE$S The average daily traffic generated by SPA I and SPA II combined is 33,364 which is 4,388 ADT greater than calculated under SPA I only. Although the additional traffic generated from the project would result in congestion if distributed to existing streetS, street improvements would be undertaken as part of the project and the Threshold policy for traffic would be maintained. The future traffic volumes on East H Street were calculated to be within the Threshold ADT determined by the City (i.e.,)6,500 ADT east of the intersection of East H Street and Hidden Vista Road) and no significant impacts are expected. B. Miti ation Measures Existing roadway conditions in the project area which include segments of Otay Lakes Road and East "H" Street are inadequate and future traffic increases associated with the project would require modifications to the circulation system in the study area. The applicant has agreed to implement these measures. The recommended mitigation measures would be phased and based on the amount of construction completed on the project. It should be noted that some of the mitigations recommended would be constructed prior to the estimated time of need. All streets internal to the project would be designed according to the classifications provided in the project description and would meet City standards. Depending on the mixture of land uses and intensity the traffic mitigation measures would vary. Mitigation measures have been tied to coordinate with phased development. The project has been anticipated to be developed in seven phases. The land uses and intensity are listed below along with the associated mitigation measure for each phase of development. In addition, the developer must enter into an agreement comparable to the development agreement for SPA I which establishes a limit on building permits based on a maximum traffic volume of 56,500 ADT or at a level that exceeds the City's Threshold Policy. Mitigations: Commercial - 0 acres Industrial - 0 acres Residential - 0 DUs o The segment of Otay Lakes Road between Camino del Cerro Grande and Ridgeback Road would be widened to ti lanes (currently being constructed). o East H Street between the 1-805 northbound off-ramp and Hidden Vista Road would be restriped for 3 eastbound lanes. o The East H Street/l-805 southbound, on/off-ramps intersection would be signalized. The existing southbound 1-805 to eastbound East H Street loop ramp would be reconfigured to pass through the signalized intersection with dual right turn lanes. The eastbound approach to this intersection would be reconfigured to provide 3 lanes. These improvements to the 1-805/East H Street interchange should alleviate forecasted traffic impacts at the inter- change through 1991. Mitigations: Commercial - .$2 acres Industrial - ti.76 acres Residential - 0 DUs o No improvements recommended. -9- Mitigations: Commerdal - (5.8 + .g2 = 6.62 acres) Industrial - (33.32 + 1.15 = 3t~.#7 acres) Residential - (l~g?l + ~g? = 2~37S DUs) o No improvements recommended. Mitigations: Commercial - (6.62 + 0 = 6.62 acres) Industrial - (3~.~7 * 2.3~ - 36. gSacres) Residential - (2~37~ + 1#0 = 2~18 DUs) o No improvements recommended. C. Monitorin~/Reportin~ Pro,ram City staff would ensure that the recommendations ~ntalned in the Transpor- tation section of the SEIR re§ardin§ road modifications are incorporated into the tentative map. D. Anal)sis of Significance Assurnin§ several road widening actions and intersection §eometry chart§es were completed as outlined in the Miti§ation Measures section, then no significant impacts tn circulation would occur. LAND USE/ClOIStRAL PLAN/ZONING A. Potential Impacts The Rancho del Rey SPA II Plan~ as proposed, is in conformance with the land use policies and plans of the City of Chula Vista, the El Rancho del Rey Specific Plan and with existing and proposed land uses in the vicinity of the project site; development of SPA ri would not result in significant land use impacts. -11- B. Mitigation Measures Because implementation of the SPA II Plan would not result in significant land use impacts, no mitigation measures are required. C. Monitoring/Reportin~ Program No mitigation measures are necessary and a monitoring/reporting program is not required. D. Analysis of Significance No significant land use impacts are expected to occur with the implemen- tation of the SPA II Plan. COMMUNITY SOCIAL FACTORS A. Potential Impacts No potential adverse impacts regarding Commmity social factors are as- sodated with the development of the proposed plan. Impacts to population, housing and employment are consistent with the El Rancho del Rey Specific Plan. B. Mitigation Measures Because no significant sodal impacts would be associated with the proposed project no mitigation measures are necessary. C. Monitoring/Reportinl~ Program No mitigation measles are necessary and a monitoring/reporting program is not required. -12- Mitil~ations: Commercial - (5.8 + .82 = 6.62 acres) Industrial (33.32 + 1.13 = 3#.t~7 acres) Residential - (1,891 + t~87 = 2,378 DUs) o No improvements recommended. Mitisations: Commerdal - (6.62 + 0 = 6.62 acres) Industrial - (3t~.#7 + 2.38 - 36.83acres) Residential - (2,375 + 1#0 = 2,5I$ DUs) o No improvements recommended. C. Monitorinff/Re~orting Pro,am City staff would ensure that the recommendations contained in the Transpor- tation section of the SEIR regarding road modifications are incorporated into the tentative map. D. Anal}sis of Significance Assuming several road widening actions and intersection geometry changes were completed as outlined in the Mitigation Measures section, then no significant impacts to circulation would occur. LAND USE/GEI~RAL PLAN/ZONING A. Potential Impacts The Rancho del Rey SPA II Plan, as proposed, is in conformance with the land use policies and plans of the City of Chula Vista, the t~1 Rancho del Rey Specific Plan and with existing and proposed land uses in the vicinity of the proiect site; development of SPA 1I would not result in significant land use impacts. D. Analysis of Significance No sigBificant commmity social impacts would result. COMMUNITY TAX STRUCTURE. A. Potential Impacts Implementation of the proposed Rancho del Rey SPA II would result in a net fiscal benefit of approximately $32,000 annually to the City of Chula Vista; therefore, no adverse impacts would result to the community tax structure. B. Mitigation Measures Because no adverse fiscal impacts are associated with the proposed project no mitigation measures are necessary. C. Monitoring/Reporting Program No mitigation measures are necessary and a monitoring/reporting program is not required. D. Analysis o[ Significance No adverse fiscal impacts are associated with the proposed project. PARKS~ RECREATION AND OPEN SPACE A. Potential Irn ~acts As part of the proposed project, a 6.5 acre neighborhood park would be developed on-site. This park would exceed the park requirements as determined by the City. The net impact to parks and recreation would be -13- beneficial. A substantial portion of the site (42%) would be dedicated as open space. There would be no adverse impacts to open space. B. Mitigation Measure!, Because no adverse impacts to parks, recreation and open space are associated with the proposed project, no mitigation measures are necessary. C. Monitoring/Reporting Program No mitigation measures are necessary and a monitoring/reporting program is not required. D. Analysis of Significance. No adverse impacts to parks, recreation and open space are associated with the proposed project. pUBLIC 5E~¥1CE A. Potential Impacts During peak demand times~ OWD cannot currently guarantee an adequate supply of water to meet the water needs of the proiect. This is regarded as a significant impact. Development of on-site sewage facilities consistent with the 1986 sewer study would provide adequate infrastructure to accommodate project flows. The location of the 69 kV line through several residential lots is regarded as a significant impact. Incremental impacts to police protection would result from development of SPA II. Emergency fire and medical response would be supplied in compliance with the Threshold Policy and no significant impaCtS are anticipated. Both the Sweetwater Union High School District and the Chula Vista City School District are involved in the planning and construction of new facilities which would provide adequate facilities for the additional students generated by the proiect. B. Mitigation Measures The development of on-site water facilities as outlined in the OWD Master Plan Update would provide adequate infrastructure for water distribution. In order to enst~e year-round water supply the applicant would be required to work with OgtD to increase water storage facilities. The City has sufficient capacity through its METRO contract to accommodate additional sewage flows generated by the project. In compliance with the Threshold Standard, the City would review the projected sewage flows and volumes for com- pliance with City Engineering Standards. The impacts associated with the existing 69 kV line would be mitigated by relocation. The increased demand on police protection would require the addition of 1.61 personnel to meet the City's Threshold Standards. Potential impacts to police protection would be reduced lo below a level of significance through net fiscal revenue generated by tho proposed project. The accrual of revenues from the proposed project would allow the City to fund the additional police personnel. Project-related impacts to schools would be mitigated through the phased implementation of additional facilities in eastern Chula Vista. The Rancho del Rey Mello Roos District (CF #3) would provide tax moneys directly to the school districts for implementation of their long-range development plans. C. Moni torin~Reporting Program Building permit issuance would be conditioned on the project's compliance with City Engineering Standards for sewage flows and volumes and the relocatian of a 69 kV transmission line. City staff would ensure that the applicant works with the OV/D to increase water storage facilities. As part of the annual review by the Growth Management Oversight Committee of the City's Threshold Policy, a review of the adequacy of police protection would be conducted~ to ensure that the Police Department has implemented a hiring policy that would allow for the addition of the required personnel. Occupancy permit issuance would be conditioned upon inspection by City staff of a signed agreement between the applicant and the City of Chula Vista School District stating that the applicant is participating in the Rancho del Rey Mello Roos District (CF #3). D. Analysis of Significance If the OWD can commit to provision oi water service to this projeCt potential impacts would be reduced below a level of significance. Development of on- site sewage facilities consistent with the 1986 sewer study would provide adequate infrastructure to accommodate project flows. The relocation of the 69 kV line would mitigate potential impacts to a level of insignificance. The addition of personnel to the police department would reduce potential impacts to below a level of significance. Development of SPA II would result in increased demand for fire protection services that would be satisfied by Station tt2 and the future station within El Rancho del Rey. The number of students generated by the SPA II would place additional demands on the existing facilities. Both Districts are involved in the near-term planning and construction of new facilities which would provide adequate facilities for the additional students generated by the projeCt. -16- CITY OF CHULA VISTA DISCLOSURE STATEMENT IAPPLICANT,S STATEMENT OF DISCLOSURE OF CERTAIN OWNERSHIP INTERESTS ON ALL APPLICATIONSI WHICH WILL REQUIRE DISCRETIONARY ACTION ON THE PART OF THE CITY COUNCIL, PLANNING COMMISSION AND ALL OTHER OFFICIAL BODIES. .

PUBLIC HEARING: Draft Environmental Impact Report EIR-89-9, General Development Plan for EastLake III/Olympic Trainin~ Center A. BACKGROUND The draft of this EIR was issued for public and Agency review on August 4, 1989. It is subject to a 30-day review period through the State Clearing (see attached letter) which will end on September 8, 1989. The only comment received as of the preparation of this staff a report are from Peter Watry and it is attached. B. RECOMMENDATION Open the public hearing, take testimony relevant to the DSEIR, close the hearing and schedule consideration of the FSEIR for September 27, 1989. It would also be helpful to give ERCE any direction in the preparation of the final report. C. PROJECT DESCRIPTION The proposed project encompasses 1030 acres and includes two primary components: a General Development Plan and annexation of EastLake III into the City of Chula Vista. The General Development Plan for EastLake III further refines and focuses the provisions of the Eastern Territories Plan to the 1030-acre project site. The General Development Plan includes two residential neighborhoods, EastLake Woods and EastLake Vistas, an expansion of the existing EastLake Business Center, and an Olympic Training Center complex with support uses. The entire EastLake III/Olympic Training Center site lies east of the current City limits, within the County of San Diego and within the City of Chula Vista's Sphere of Influence. Discretionary actions related to the project include pre-zoning and annexation of the property to the City of Chula Vista and a General Development Plan approval. Ultimately, additional approvals will include Sectional Planning Area (SPA) Plans, Public Facility Finance Plans, Development Agreements, and tract/parcel maps prior to construction of the proposed land uses. These additional approvals are not analyzed by this SEIR and will require subsequent environmental review. Alternative E During preparation of this SEIR, refinements in project design have been created to reduce various potential impacts, especially regarding compatibility with adjacent uses and open space buffer concerns along the Otay Lakes western boundary (project site eastern boundary). These City Planning Commission Agenda Item for Meeting of September 13, 1989 Page 2 refinements have resulted in Design "Alternative E." Section 6 of the DSEIR provides a detailed description, illustration and comparison of Alternative E to the proposed project. Alternative E generally proposes an increase in open space along the east project boundary (buffer to Otay Lakes) and various residential density alterations. D. IMPACT ANALYSIS 1. Land Use The project will result in development of currently undeveloped land (previously analyzed in MEIR 81-03; EastLake Planned Community approved in 1982), into a mixed-use community consisting of the following uses. Residential: 438.1 acres (2008) units Industrial: 91.5 acres (research and manufacturing) Commercial: 45.8 acres (15.0 retail and 30.8 visitor commercial) Public/Quasi Public: 175.0 acres (25 acres school; 150 acres OTC) Parks & Recreation: 58.4 acres Open Space: 169.0 acres Potential land use impacts include incompatibility with adjacent uses, specifically and especially sensitive open space of the Upper and Lower Otay Reservoirs (immediately east of the project site). The compatibility impacts can be mitigated by project design and measures proposed herein (i.e., setbacks, landscaped slopes, etc.), in conjunction with selection of Alternative E (refer to Section 6 of the DSEIR). All project and cumulative land use impacts can be mitigated to a level below significant. 2. Transportation and Circulation The project will generate 65,300 average daily vehicle trips (52,100 trips to external roadways), which represents a significant contribution to future roadway traffic in the area. As an integral project of the Eastern Territories Transportation Phasing Program (TPP), project traffic and other ongoing development were comprehensively assessed in July/August 1989. Roadway improvements to offset development have been identified and allocated to the TPP phasing. Project and cumulative traffic generated in the future can generally be mitigated by circulation improvements of the City Eastern Territories TPP, proposed as mitigation in this Draft EIR. One outstanding roadway segment (Telegraph Canyon Road from SR-125 to EastLake Parkway) and one intersection (Telegraph Canyon Road/EastLake Parkway) cannot be mitigated to acceptable levels of service (LOS C) by measures proposed in the TPP and included in this City Planning Commission Agenda Item for Meeting of September 13, 1989 Page 3 EIR. These two locations present an unmitigated cumulative impact as identified at this point in time. If improvements were reformulated and accepted by the City at future planning stages, this impact could be mitigated to an acceptable level. 3. Public Services and Utilities The project will result in an increase in demand for services and utilities (evaluated in Section 4.3), and will necessitate construction of various water, sewer, school, park and other facilities to serve the 2008 residences, OTC and other development proposed. All project-specific potential impacts can be mitigated by measures included in Section 4.3, some of which require further analysis during subsequent planning stages and refinement of facilities' plans. The project's contribution to cumulative impacts regarding water supply, sewer treatment capacity and non-renewable energy resources cannot be fully mitigated; these cumulative impacts are considered unavoidable and cumulatively significant. 4. Visual Resources Project development will permanently change the existing natural character of the site to a mixed-use urban community. Aesthetic and visual impacts can be mitigated to an insignificant level on a project-specific basis by sensitive design, landscaping and open space buffers. On a cumulative basis, the project will contribute to an unavoidable cumulative impact on the existing natural character of the site and surrounding area. 5. Geology/Soils Geotechnical constraints onsite (i.e., fault traces, expansive or erosive soils, landslides) can be overcome by standard measures proposed herein and at future implementation stages. No significant impacts will result after mitigation is considered; no cumulative impacts have been identified. 6. Hydrology/Water Quality Development of the site will result in an increase in runoff to downstream areas. Since the site is located at the headwater regions of the three drainage basins, onsite flooding is not of concern. Downstream flooding potential, impacts to the Otay Lakes area and water quality impacts would result, requiring flood control improvements and drainage and runoff control facilities. Specific drainage and water quality control plans are required at later site design stages by measures herein; these will serve to mitigate project and cumulative flooding and water quality impacts to level of insignificance. City Planning Commission Agenda Item for Meeting of September 13, 1989 Page 4 7. Cultural Resources One important archaeological site {SDI-976) will be impacted by project development. The geologic Otay and Sweetwater Formations onsite are considered to possess high sensitivity for paleontological resources. These impacts can be mitigated by salvage and monitoring activities (measures in the SDEIR) to an insignificant level. 8. Air Quality Project vehicle and stationary emissions will increase air pollutants in the area. Because the project site is assumed as open space in the SANDAG Series V, VI and VII growth forecasts, project development has not been included in formation of air quality attainment plans. Therefore, the project is found to create a significant cumulative air quality impact which cannot be fully mitigated. Transportation management measures will reduce these impacts slightly, to the extent feasible. On a local basis, project traffic will be offset by transportation/ roadway improvements {required as conditions of approval) which will ensure acceptable roadway and intersection levels of service. This will verify that potential local "hot spot" air pollution impacts will be mitigated to an insignificant level. Short-term local construction-related air quality impacts can also be mitigated by proper construction procedures. 9. Noise Project traffic and urban development will increase ambient noise levels in the project vicinity. Based on projected future cumulative traffic volumes on nearby roadways {see Traffic analysis contained in this SEIR), various locations onsite will require noise attenuation measures to realize acceptable noise levels at project buildout. Acceptable onsite noise levels will be attained by measures later defined at the SPA Plan and subdivision levels (i.e., building setbacks, noise attenuation by site and/or building design, etc.). Further noise analysis is required prior to final site design, in order to define specific measures necessary for adequate noise attenuation. Upon implementation of further study (required as mitigation in the DSEIR) and onsite noise mitigation, project and cumulative impacts can be mitigated to a level of insignificance. lO. Biological Resources Onsite resources defined as biologically important and/or sensitive exist in the southern site area (Figure 4-11), and include potential vernal pools and various plant and animal species associated with the coastal sage scrub habitat. Impacts to these biological resources can be avoided by guaranteeing the designated park as open space City Planning Commission Agenda Item for Meeting of September 13, 1989 Page 5 (located south of the OTC site). Measures proposed in Section 4.10 of the DSEIR will serve to mitigate project and cumulative impacts to an insignificant level. ll. Socioeconomic Factors and Fiscal Analysis The project will house approximately 5,422 people in its residences, contributing slightly to demands on public services and utilities. The commercial, industrial and OTC related uses will provide employment opportunities, a beneficial impact. The project will have an overall positive fiscal impact on the City. No significant negative socioeconomic or fiscal impacts will result from project implementation. WPC 6713P September 7, 1989 To: Members of the PLANNING COMMISSION City of Chula Vista From: Peter Watry 81 Second Avenue Chula Vista, CA. 92010 Subject: EastLake Ill/Olympic Training Center E. I. R. I regret that I will not be able to attend the Publc Hearing on September 13 so I am using this means of addressing my concerns to you relative to the subject E.I.R. I wish to take this opportunity to urge the following three changes and improvements in the Draft Supplemental Environmental Impract Report, Case No.: EIR-89-11. 1. { Page 1.5 } At the top of page 1-5 it says "Proposed land uses are generally consistent with the July 1989 City adopted General Plan Update, although GDP project approval requires a General , Plan Amendment due to minor changes in land use densities and school and park revised locations, etc. (italics added). Similar statements are found throughout this E.I.R. The EastLake III/Olympic Training Center project being proposed is not consistent with the recently adopted General Plan and the changes being suggested are not "minor." Whether these changes are a good idea or not is another matter, but the E.I.R. is incorrect in saying that the changes are minor. The facing Figures 2-4 and 2-5 on what would be pages 2-6 and 2-7 sum up the story. First may I draw your attention to the area south of Orange Avenue where the Olympic Training Center will be located. On Figure 2-4, which represents "Scenario 4," it looks to be about 100 acres of "Low" density that could be developed. At a target range of 2 per acre, that would be about 200 homes. 200 homes times a trip generation factor of 10 means that that area would generate about 2,000 automobile trips per day. Figure 2-5 includes the Olympic Training Center and some commercial in that same area south of Orange Avenue. According to Table 3-1 on page 3-3 of Appendix A, that area will generate 26,789 automobile trips per day. So the proposed change south of Orange Avenue will generate more than ten times more traffic than the adopted General Plan would have generated. That change is not consistent with the General Plan, nor is that change "minor." Whether good or bad, the O.T.C. represents a very significant change in land use from the adopted General Plan. For the entire project of EastLake III and the Olympic Training Center, the plan shown on Figure 2-4 would have generated about 23,000 automobile trips per day. The plan shown on Figure 2-5 will generate more than 65,000 automobile trips per day -- almost a tripling of the traffic being generated over the entire project. And this is being done at the extreme eastern edge of Chula Vista. These changes are not consistent with the adopted General Plan nor are the changes "minor." The plan shown on Figure 2-4 would produce 1,249 dwelling units at "target." The plan on Figure 2-5 proposes to produce 2,008 dwelling units (a 61% increase)plus a large Olympic Training Center p/us much more commercial acreage p/us a slightly enlarged I-R area. These proposals significantly change the entire nature of the area from a low-density "rural" feeling to an intensively developed urban area. Good or bad, that is a very significant change. Again, whether these changes are a good idea or not is another matter. But it is repeated several times thoughout the E.I.R. that these changes are consistent with the adopted General Plan and that these changes are minor. The proposals are not consistent with the adopted General Plan nor are the changes "minor." 2. In Section 6 on "Akematives," only two alternatives are discussed: "No Project" and "Alternative E." (In terms of impacts on the rest of the City, "Alternative E" is no alternative at all. It is really just the same as the proposal.) The most obvious alternative that is not mentioned is the General Plan that was just adopted last July. That would be basically Figure 2-4 with the Olympic Training Center substituted south of Orange Avenue. Since that is, in fact, what is, that alternative deserves analysis. 3. On page 4-31 and 4-32 the E.I.R. discusses the topic of water. The discussion on water in this E.I.R. presumes that the only problem with water is a matter of pump stations, reservoirs, and pipes. It is silent as to where the additional water is going to come from to put in these facilities. Three facts instantly come to mind. (1) The Otay Water District has for many years now been using more than their legal entitlement of water because other districts have been using less than their entitlements. One of those other districts has been the City of Los Angeles. The City of Los Angeles uses less than their legal entitlement of M.W.D. water because they have had their own supply through the aqueduct from the Mono Basin (Owens Valley). As you may know, southem Califomia has been hoping to get an additional 100,000 acre-feet of water from the Imperial Irrigation District by paying to line their irrigation channels and then sending us the water being conserved. A recent newsletter from the Metropolitan Water District says that the City of Los Angeles may end up getting almost all of this because courts may likely cut down the amount that they can take from the Mono Basin by 80,000 acre-feet. (2) As I am sure you know, the State of Arizona is entitled to half of the water that we have been receiving from the Colorado River. They are now only taking about 30-40 per cent of that entitlement, I believe, but within a decade their Central Arizona Project is expected to be completed. (3) Many areas in northern California are now rationing water one way or the other. It does not seem probable that we can expect any more water from northern California when we are not even rationing ourselves. For a project as large as EastLake, I believe this matter of water availability deserves to at least be addressed and not allowed to just be ignored.

PUBLIC HEARING: Conditional Use Permit PCC-90-04; request to establish a motorcycle sales and service facility at 345 "E" Street - Thomas A. HorninQ A. BACKGROUND This item is a proposal to locate a motorcycle sales and service facility in an existing building at 345 "E" Street in the C-T zone. The Environmental Review Coordinator conducted an Initial Study, IS-90-O1, of potential environmental impacts associated with the implementation of the project. Based on the attached Initial Study and comments thereon, if any, the Coordinator has concluded that there would be no significant environmental impacts, and recommends adoption of the Negative Declaration issued on IS-90-O1. B. RECOMMENDATION 1. Based on the Initial Study and comments on the Initial Study and Negative Declaration, find that this project will have no significant environmental impacts and adopt the Negative Declaration issued on IS-90-O1. 2. Adopt a motion to deny PCC-90-04 based on the finding contained in Section E of this report. C. DISCUSSION Adjacent zoning and land use North - R-1 - Apartments South - C-T - Commercial East - C-T & R-1 - Commercial & duplex West - C-T & R-3 - Commercial & apartments £xistin9 site characteristics The project site involves two parcels totaling 0.47 acres at the northeast corner of "E" Street and Garrett Avenue. A former furniture store containing 14,900 sq. ft. of floor area occupies the southerly parcel which is zoned C-T. An R-3 parcel, which measures 50' x 134', is located directly to the north and serves as the parking and loading area for the building with access off Garrett Avenue. The use is located within the Downtown Parking District which provides on- and off-street public parking in lieu of the requirement for private off-street parking. There are seven metered on-street spaces contiguous to the site. The closest public parking lot is located some 250 ft. to the southeast on the opposite side of "E" Street. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 2 Proposed use The proposed use would involve the rear or northerly 10,400 sq. ft. of the building as well as the abutting parking area. The remaining 4,500 sq. ft. at the front of the building adjacent to Street would remain available for a separate commercial use. The exterior of the building would remain unchanged except for repainting and signage. The floor plan shows a 3,100 sq. ft. display area at the northeasterly portion of the building with pedestrian access from the front of the building via a corridor to "E" Street. An 1,800 sq. ft. service area is located at the northwesterly corner of the building with an overhead door off the rear parking area. The parking area would provide spaces for 13 automobiles and 9 motorcycles, with a wash area shown in the southeast corner. Concrete block walls would be added to the westerly, easterly and southerly perimeter to match the existing 5 ft.-high wall along the northerly boundary. The facility is proposed as a franchised dealership offering sales, service and repair, as well as the retail sales of parts and a full line of accessory items including clothing. The proposal is to conduct all activities indoors, with no exterior display, storage or repair of vehicles. The use would employ 10 people and operate between the hours of 9:00 a.m. and 6:00 p.m., Tuesday thru Saturday, and 10:00 a.m. to 4:00 p.m. on Sunday. D. ANALYSIS A1 though the property is wi thin the Parking District, we believe it is still appropriate to address the issue of parking in the case of a conditional as opposed to permitted use. The Code is not specific wi th regard to required parking for this type of facility, al though it would be expected to be significantly less than many retail uses which could occupy the site as a matter of right. The applicant has submitted survey information which indicates that parking demand at his present location -- South Coast Harley Davidson at 2248 Main Street -- generally does not exceed 10 cars and 10 motorcycles at any one time. Two staff site checks would appear to confirm that the demand is modest in comparison to the floor area, and would not present a problem at the new site. Note: With regard to the remaining 4,500 sq. ft., the parking needs for a permitted use would be considered to be met by virtue of its location in the Parking District. A conditional use would be evaluated on its own merits. City Planning Commission Agenda Items for Meeting of September 13, 1989 Page 3 The primary issue is noise. The proposal is to provide internal ventilation and exhaust systems in order that all work can be conducted inside with the overhead door closed except at the beginning and end of the day and brief periods in between. A noise study based on the applicant's Main Street operation indicates that noise from normal shop activities should be significantly less than the City's noise standard when the door is closed, and when the door is open. The noise approaches the maximum allowed but does not violate the City standard. Shop operations are considered "environmental noise," which is under the control of the applicant, and for which standards have been established. The other category of noise is called "nuisance noise," over which the applicant has little if any control, and which are not the subject of specific standards but are addressed on a case-by-case basis, usually as a result of a complaint. For instance, the study refers to the nuisance noise of revving of engines in the parking lot which "should not be permitted by the owner." Realistically, the owner has little control over customers in the parking lot, and none at all over off-site arrivals and departures. The parking lot directly abuts residential uses to the north and east, and a single family area extends to the north along Garrett Avenue. It is our opinion that the likelihood of "nuisance noise" from motorcycles in and around the parking lot, as well as the possibility of test runs and departures funneling back through the neighborhood to the north to avoid the heavy traffic and unsignalized intersection at "E" Street, would be a constant source of zoning complaints and disturbance to the surrounding residents. For this reason, we are recommending denial of the request. E. FINDINGS The nature, location, and access for the use would likely create adverse noise impacts on surrounding residents.

Project Setting The project setting consists of two parcels located at the northeastern corner of Garrett and "E" Street in central Chula Vista. The northern parcel is currently developed as a parking lot. The southern parcel which fronts on "E" Street is the site of a furniture warehouse and storage business. Adjacent land uses include multi-family residential on the north, an auto parts store, ballet studio, auto supply on the south, florist and printer on the east and auto body, fender repair, auto repair, appliance repair and a fast-food restaurant under construction on the west. Pedestrian access to the project is currently provided from the parking lot to the north or metered parking south of the project on the north side of "E" Street. 8. Project Description The proposed project will involve the conversion of the existing furniture storage and warehouse business to a new motorcycle dealership and general retail space. The present one story building has a floor area of 14,866.6 and 13 on-site parking spaces. The proposed project will not adjust the size of the building. The existing project currently has 13 parking spaces. C. Compatibility with Zoning and Plans Because the General Plan designations and zoning differ on the two parcels involved staff's comments on compatibility of the proposal with the General Plan and Zoning Ordinance will deal with each parcel separately. The northern parcel of this proposal is designated as Medium Density Residential on the General Plan and R-3 Apartment Residential in the Zoning Ordinance. Off-street parking is allowed as a conditional use in the R-3 zone. Therefore, the proposed use of this parcel as a parking lot is in conformance with the zoning and the general plan. city of chula vista planning department ¢13Y OF environmental review section (~HUL~ VISTA -2- The southern parcel of this proposal is designated as Commercial Thoroughfare on the General Plan and is zoned for Commercial Thoroughfare. Motorcycle sales and service are permitted as a conditional use permit in the commercial thoroughfare zone. If a conditional use permit is granted, this project will be in conformity with the General Plan and Zoning Ordinance. D. Compliance with the Threshold/Standards Policy 1. Fire/EMS The estimated Fire/EMS response time is 3 minutes, which is within the 7 minute threshold standard. 2. Police The Police Department is currently maintaining an acceptable level of service based on the threshold standard and this project will not change or impact the current level. 3. Traffic The proposed project would not generate additional traffic. Therefore the current level of service "C" will be maintained. This meets the Threshold Standard Policy for Chula Vista. 4. Park/Recreation The Parks and Recreation Department has reviewed the project proposal. As this is a commercial project, there will be no impact on the parks and recreation services. 5. Drainage Review of the development proposal has resulted in the determination that surface drainage flow and drainage design meet established engineering standards. 6. Sewer The existing 8" sewer main on Garrett flowing southerly on "G" is adequate to serve the proposed project; thus the threshold standards are met. 7. Water The project site is located within a previously established urbanized area with water supplies adequate to meet established threshold standards. 8. Noise The dominant source of noise at the present location of the business comers from pneumatic tools and an air-compressor in the repair shop area. Field measurements were taken from inside the shop area with -3- the door closed to eliminate the high ambient noise from the surrounding industrial area. The results of these measurements indicate a general noise environment in the service bay area of approximately 66.3 dBA, equivalent sound level (Leq). To quantify the noise impact at the future location, field measurements of existing ambient noise levels were made near the residential boundary behind the shop. This location was chosen because it is the closest residential area to the proposed shop area. The measurements were taken at l:O0 p.m. on August 29, 1989. Figure 3 shows the measurement location in relation to the shop, the street, and the residential units. The principal noise sources at the future site were the passing vehicles on Garrett Avenue and "E" Street. The measured ambient noise level at the future site was 55.2 dBA, Leq. Table 2 presents a summary of existing ambient noise levels measured at the future site. The City of Chula Vista noise standard considers environmental noise and nuisance noise. This analysis assumes that the normal shop operations associated with permitted activities would be environmental noise. Operation of vehicles in the parking lot at high rpm would be considered nuisance noise and should not be permitted by the owner. This analysis assumes the repair operation will occur only between the hours of 7:00 a.m. and 10:O0 p.m. Further, the applicant plans to operate the repair shop with the vehicle entry door closed, except for periods of less than one hour at the start and end of the day when customers will be leaving and picking up vehicles and very short single-vehicle entry and exit periods. An incentive to operating with the doors closed will be the maintenance of the air conditioned environment. Motorcycle engine exhaust will be vented to the roof through tubing. The building to be used at the future site is made of solid concrete construction. Noise generated in the proposed new location will be attenuated by the building. With the doors closed, structures of this type will attenuate noise by more than 20 dBA. There is additional noise attenuation from the building to the neighboring residences provided by an existing five-foot-high block wall. With the roll-up door open, there will still be attenuation. During normal operations, the noise generated from the shop, measured at the property line, should be significantly less than 60 dBA. For those short periods when the door is open, noise levels may approach dBA, but should not violate the noise ordinance. There will be no significant impact and therefore, no mitigation is recommended. -4- E. Identification of Environmental Effects No potentially significant and adverse environmental effects have been identified for the project at this time. F. Mitigation necessary to avoid significant effects As no significant effects are expected, mitigation is not needed. G. Findings of Insignificant Impact Based on the following findings, it is determined that the project described above will not have a significant environmental impact and no environmental impact report needs to be prepared. 1. The project has the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory. The project site is urban in nature, located in a developed area and devoid of sensitive habitat or species; therefore, the project does not have a potential to degrade the quality of the environment or curtail the diversity of the environment. 2. The project has the potential to achieve short-term environmental goals to the disadvantage of long-term environmental goals. The proposed project, should the conditional use permit be granted, will be in conformance with the City zoning and land use designations identified in the Chula Vista General Plan. Thus, it would not achieve any short-term objectives to the disadvantage of longer term goals. 3. The project has possible effects which are individually limited but cumulatively considerable. As used in the subsection, "cumulatively considerable" means that the incremental effects of an individual project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects. This commercial proposal will result in no significant cumulative environmental impacts. -5- 4. The environmental effects of a project will cause substantial adverse effects on human beings, either directly or indirectly. The proposed project will not cause substantial adverse effects on human beings, either directly or indirectly. H. Consultation 1.

Figures 1 and 2 show the vicinity and specific location of the store. The applicable noise standard for assessing the impact is the City of Chula Vista, Performance Standard and Noise Control 19.68.030, which requires that the noise generated by operations at the motor cycle shop not exceed an average sound level, I~q, of 60 decibels (dBA) at the boundary of the adjacent multi- family residential property, between the hours of 7:00 a.m. and 10:00 p.m. Two sets of noise measurements were taken. First, noise levels at the existing business operation were measured during normal working conditions. Second, ambient noise levels were measured at the furore site near the residential boundary. Analysis of the noise sources, the construction of the future building, and the site geometry indicate that the noise source at the future site will not exceed 60 dBA at the residential boundaries, and thc noise standard will not be violated. lI. METHODS OF ANALYSIS Existing noise levels at both sites were measured with a Metrosonic dB-308 Sound Analyzer, a programmable solid-state recording device which records noise levels for preset intervals. The recorder was set with the following parameters: Filter: A weighted Response: Slow (1/8 second response) Measurement Interval: 30 seconds Measurement Period: 15 minutes The recorder was calibrated prior to and following the measurements. IlL DESCRIPTION OF THE EXISTING NOISE ENVIRONMENT The dominant source of noise at the present location of the business comes from pneumatic tools and an air-compressor in the repair shop area. Field mea- surements were taken from inside of the shop area with the door closed to elim- inate the high ambient noise from the surrounding industrial area. The results of these measurements indicate a general noise environment in the service bay area of approximately 66.3 dBA, equivalent sound level (Leq). Table 1 presents a summary of the noise measurements taken at the existing site. To quantify the noise impact at the the future location, field measurements of existing ambient noise levels were made near the residential boundary behind the shop. This location was chosen because it is the closest residential area to the proposed shop area. The measurements were taken at 1:00 p.m. on August 29, 1989. Figure 3 shows the measurement location in relation to the shop, the street, and the residential units. The principal noise sources at the future site were the passing vehicles on Garrett Avenue and E Street. The measured FIGURE 2.

FUTURE ACOUSTICAL CONDITIONS The City of Chula Vista noise standard considers envh'onmental noise and nuisance noise. This analysis assumes that the normal shop. operations associ- ated with permitted activities would be environmental noase. Operation of vehicles in the parking lot at high rpm would be considered nuisance noise and should not be permitted by the owner. This analysis assumes the repair operation will occur only between the hours of 7:00 a.m. and 10:00 p.m. Further, the applicant plans to operate the repair shop with the vehicle entry door closed, except for periods of less than one hour at the start and end of the day when customers will be leaving and picking up vehicles, and very short single-vehicle entry and exit periods. An incentive to operating with the doors closed will be the maintenance of the air condi- tioned environment. Motor-cycle engine exhaust will be vented to the roof through tubing. The building to be used .at the future site is made of solid concrete consmacfion. Noise generated in the proposed new location will be attenuated by the building. With the doors closed, structures of this type will attenuate noise by more than 20 dBA. There is additional noise attenuation from the building to the neighboring residences provided by an existing five-foot-high block wall. With the roll-up door open, there will still be some attenuation. During normal operations, the noise generated from the shop, measured at the property line, should be significantly less than 60 dBA. For those short periods when the door is open, noise levels may approach 60 dBA, but should not violate the noise ordinance. V. IMPACT AND MITIGATION There will be no significant impact and therefore, no mitigation is recommended. 6 TABLE 2 NOISE LEVEL MEASUREMENT DATA AT FD'TURE SITE Measurement Noise Period Level 1 55.3 2 59.5 3 59.2 4 55.7 5 59.0 6 57.6 7 55.7 8 52.8 9 57.6 10 56.7 11 55.0 12 51.3 13 55.2 14 57.0 15 54.1 16 51.9 17 52.3 18 49.3 19 51.4 20 54.3 21 49.1 22 52.1 23 50.5 24 52.4 25 56.9 26 50.8 27 56.2 28 55.4 29 51.4 30 53.4 Level During Total Measurement Period = 55.2 dBA CITY OF CHULA VISTA DISCLOSURE STATEI~NT IAPPLiCANT,SSTATEMENT OF DISCLOSURE OF CERTAIN OWNERSHIP INTERESTS ON ALL APPLICATIONS WHICH WiLL REQUIRE DISCRETIONARY ACTION ON THE PART OF THE CITY COUNCIL, PLANNING COMMISSION AND ALL OTHER OFFICIAL BODIES.
