Background: A Sewer Master Plan is required by the Otay Ranch General Development Plan/Subregional Plan for each Otay Ranch village at the SPA level of planning. Overview: SPA One is within the Telegraph and Poggi Canyon sewer basins and will be served by interceptors within those basins. The report prepared by Wilson Engineering, entitled Overview of Sewer Service For Specific Planning Area 1 of the Otay Ranch Project dated Revised June 14, 1995 (SMP), addresses the impacts to the existing facilities within those basins, required new improvements and the cost of those facilities. The costs indicated in the report will be used in the Public Facilities Financing Plan (PFFP) and will be discussed at the workshop with that documents discussion. Each basin was evaluated utilizing sewerage generation criteria contained in Tables 2-1 and 2-2, approved development plans within each basin and development indicated in the April 21, 1995 SPA Plan. It should be noted that different generation factors were used in the analysis of the two basins. The reason for the difference will be discussed in the write-up for that basin. TELEGRAPH CANYON BASIN Approved Improvement and Financing Plans The City Council has adopted two programs for providing improvements and financing of sewer facilities within the Telegraph Canyon Basin The first program, entitled Telegraph Canyon Sewer Basin Improvement and Financing Plan dated July 1992 (TCSB92), was adopted to establish improvements within the natural gravity basin necessary to serve the proposed development as determined by the Growth Management Program (GMP). The GMP forecast was based upon final maps, tentative maps, general development plans approved in 1992 and an estimate of the development within the Otay Ranch. Planning Commission August 30, 1995 Page 2 The second study entitled Telegraph Canyon Sewer Basin Improvement and Financing Plan Amendment Incorporating Pumped Flows dated June 9, 1993 (TCSB93) expanded the study to include proposed pumped flows from a portion of EastLake Greens and the Olympic Training Center. The studies determined a fee for both situations and improvements required under each scenario Developers are required to either pay the appropriate fee or upgrade the interceptor as indicated in the studies. Sewerage Flow Projections Table 2-1 of the SMP indicates the generation rates used in the two adopted studies for the Telegraph Canyon Basin. The rate of 250 gallons per day (gpd) per unit for single-family residential and 187 gpd/unit for multi-family was determined by staff to be appropriate for the Telegraph Canyon Basin because that was the approximate average for the existing development within the basin as determined by metered flow Replacement and Design Criteria Existing sewer Jines were not considered deficient until the ratio of the depth of flow in the existing main (D) to diameter of existing sewer main (d) exceeded 0.85 (ratio D/d).- Therefore, the flow in the existing sewer main is allowed to reach D/d of 0.85 before upgrading of the main is required. The existing system will be metered at critical locations to determine when improvements will be needed. Although a higher D/d ratio is allowed prior to requiring a portion of existing main to be replaced or paralleled, design of all replacement or parallel pipes is required to be based upon peak flows of 0.50 D/d for 12 inch diameter facilities and smaller and 0.75 D/d for pipes larger than 12 inches in diameter. Designing at the lower D/d ratio provides a larger margin of safety to account for underestimated flows which may occur due to land use changes. SPA One Impact As indicated in Table 3-4 of the SMP, SPA One will contribute less total equivalent dwelling units (EDU) to the Telegraph Canyon Interceptor than considered in the reports approved by the City Council. Consequently, the impact of SPA One is less than anticipated by the approved studies. No additional evaluation was required in the SMP to revise the previously approved plans because they reflect a conservative analysis. City staff periodically revises the fee program to include updated costs and changes to the plan as a result of differences associated with more precise development plans as compared to those cO!1.sidered in the last update. Staff will include the changes associated with SPA One and other changes with the next update. Planning Commission August 30, 1995 Page 3 POGGI CANYON BASIN Sewerage Flow Projections The Poggi Canyon Sewer Basin was analyzed in the same manner as the Telegraph Canyon Gravity Basin (TCGB) except that the generation rates were changed to use the City standard of 280 gpd/unit for single-family and 210 gpd/unit for multi-family. The higher rates were used to be conservative because a larger percentage of the basin is undeveloped in comparison to the TCGB. By doing so, sizing of new portions of the Poggi Canyon Interceptor as well as replacement or parallel installations will definitely be adequate to serve future needs. Densities of 10 dwelling units per acre (DU/ AC) or less were considered single-family units and densities of greater than . I) DU/ AC were considered multi-family. Sewage generation was determined based upon currently approved SPA and General Development Plans within the basin using the rates for the various uses listed in Table 2-2. Replacement and Design Criteria Portions of the existing sewer main were considered for replacement when the D/d of 0.60 was met for 8- and 1O-inch mains and 0.85 D/d for mains 12 inches and larger. As with the TCGB, new segments, parallel or replacement lines are required to be designed as follows: 0.50 D/d for mains 12 inches in diameter or less and 0.75 D/d for mains greater than 12 inches in diameter Poggi Canyon Interceptor Analysis Four flow scenarios were modeled using a computer program to determine when eXlstmg segments of main would need to be replaced and what size of main would be required for new and upgraded segments based upon the replacement and design criteria indicated above. Page 15 of the SMP indicates what each computer run was intended to provide. Results of the Analysis The results of the computer analysis are indicated on page 16, in Table 4-2 on page 17 and on Exhibit "C" of the SMP. Table 4-2 depicts the number of additional dwelling units which can be accommodated by the existing segments of the Poggi Canyon Interceptor. As indicated in Table 4-2, there are segments of the existing line which are currently overloaded and will be required to be replaced prior to any development. The table also designates the replacement size necessary to accommodate ultimate buildout flow. Funding of Facilities Funding of required improvements will be determined in the future. The developer has indicated that they may work with the other two land owners (EastLake and Sunbow) to see if each will contribute toward construction of the improvements stated in the SMP report. If an agreement is not reached, the developer may be required to construct the improvements and have the City establish a reimbursement district. Another possibility would be for the City to adopt a fee program similar to that established for the Telegraph Canyon Basin. Planning Commission August 30, 1995 Page 4 SPA One Impact Development of SP A One will require the installation of on-site sewer mains to the sizes shown on Exhibit "C" between nodes 311 and 315. In addition, Table 4-4 indicates additional off-site improvements which will be required as conditions of approval of the tentative map to be installed with full development of SPA One. Segments of the existing system will be replaced with the size of sewer main indicated on Exhibit "C" when those facilities exceed the criteria indicated above. Sewer metering will be required at critical locations in the system as directed by the City Engineer. Table 4-2 will be used as a guide in determining when improvements will be required. Timing of sewer improvements will be included in the conditions of approval for the tentative map. ON SITE SEWER PLAN (Both Basins) Exhibit "A" depicts a possible on-site sewer layout within SPA One. This layout should be considered conceptual in that the final design will not be known until detailed grading and improvement plans have been prepared. Exhibit "A" was used to determine where proposed flows would be introduced into the Telegraph and Poggi Canyons Interceptors in order to determine impact to existing facilities and to design new facilities. Some variation will occur with final design of the development.

Background: A water conservation plan is required the Otay Ranch General Development Plan/Subregional Plan (GDP/SP) for each Otay Ranch village at the SPA level of planning. The Environmental Impact Report (EIR) for the GDP/SP also required a WCP as mitigation. Goals: Promote water conservation through increased efficiency in essential uses and use low water demand landscaping. Elements of the Water Conservation Plan: 1. Analysis of water use 2. Compliance with the Metropolitan Water Districts (MWD) Water Use Efficiency Guidelines. 3. Water Conservation Measures a) Indoor b) Outdoor c) Other 4. Water Conservation Costs Analysis of Water Use: The WCP has an estimate of the potable and reclaimed water demands included as Tables 1 and 2. The Policy Committee made the decision that only parks and open space will be required to be irrigated with reclaimed water consequently, the WCP only included estimated use in those areas, whereas, the Water and Reclaimed Water Master Plan (SAMP) estimates assume use on all area allowed by law and the health department. The SAMP included some areas that potentially could utilize reclaimed water in the future to assure that the facilities to be installed will have adequate capacity to supply the reclaimed water, if available. The difference in the estimates has no impact on the conclusions or recommendations of the WCP, therefore, the numbers have not been requested to match in both plans. Planning Commission August 30, 1995 Page 2 MWD Water Use Efficiency Guidelines: These guidelines are required to be met by MWD when an area is annexed into the district All of SPA One is currently within the MWD, therefore compliance with the guidelines is not required, however, many of the guidelines are being addressed by the City in the SAMP and Drainage Master Plan (DMP). Appendix "A" contains MWD's guidelines Water Conservation Measures: Some water conservation measures are required by the State of California and by the Chula Vista Municipal Code. Faucets are required to have a maximum flowrate of 2.2 gallons per minute and toilets must comply with a 1.6 gallon per flush requirement. These measures are mandatory and will be included in the construction of the structure The WCP considered additional measures and have separated those measures into indoor, outdoor and other measures. A full discussion of those measures is contained on pages 6 through 9 and Appendix "B" of the WCP. Water Conservation Cost: Various methods of water saving measures were analyzed to determine which had benefit/cost ratios which would make the measure feasible to implement. A benefit/cost ratio of greater than I represents a measure that would be cost effective. Table 4 depicts the measures considered in the WCP. Items recommended for implementation in SPA One all have benefit Cost Ratio's greater than 1. Attachment: Water Conservation Plan dated July 25,1995. WORDlWAU\PLACOMWC.DOC PLANNING COMMISSION INFORMATIONAL MEMORANDUM August 30, 1995 TO: Chairman Tuchscher and Members of the Planning Commission FROM: Otay Ranch Project Team SUBJECT: Water And Reclaimed Water Master Plan Recommendation: Review and discuss the Subarea Master Plan (SAMP) for water and reclaimed water and direct staff to make changes, if necessary. Background: A water and reclaimed water master plan is required by the Otay Ranch General Development Plan/Subregional Plan for each Otay Ranch village at the SPA level of planning. Both water and reclaimed water operations are controlled by the Otay Municipal Water District (OMWD). The plan before you has been reviewed by OMWD as well as City staff. The SAMP was evaluated based upon the April 21, 1995 SPA One submittal. Process in Reviewing the SAMP: Since OMWD controls the approval of master plans for water and reclaimed water facilities, the City's review was focused on the water application rate, locations where reclaimed water will be used along with application rate, and meeting EIR and GDP requirements The EIR required that a Reclaimed Water Uses and Restrictions Plan be prepared in conformance with the Water Reclamation Plan and current engineering and health standards to promote the maximum use of reclaimed water allowed by law. A separate plan has not been prepared because the SAMP was prepared with those issues considered and incorporated in the planned facilities. See Attachment "A" for more detail of issues addressed (Response to Barabara Bamberger). Contents Of The SAMP: The SAMP determines the on-site and off site facilities needed to provide service to SPA One. The plan also estimates the water and reclaimed water demand created by SPA One and estimates the cost of the facilities. Figures 4-6 and 5-3 depict the onsite and offsite facilities determined by the study to be required for the development of SPA One. Potable Water System (PWS): SPA One is in OMWDs Central System 711 and 980 pressure zones. However, the proposed grading of the site permits the development to be served by the 711 Pressure Zone. Water will ultimately be delivered by two pumping stations. One station is currently operating and a future station will be built in the same structure as a proposed 980 pressure zone station. Planning Commission August 30, ] 995 Page 2 Operational Storage is required to provide 1.3 times the maximum day demand plus fire flow The existing reservoirs do not have adequate storage capacity to meet OMWD criteria Additional reservoir capacity is required for SPA One development. One reservoir will have to be provided to meet the demand. Two storage facilities are proposed to be provided and are in the OMWD Capital Improvement Program (CIP) and will ultimately be constructed by OMWD. Terminal Storage Facilities are also required to provide a five day water supply to the area for emergency use. Adequate Terminal Storage is available to provide for development of SPA One (OMWD has recently reduced their policy relative to storage requirements from a 10 day supply to a 5 day supply). Reclaimed Water System: Currently reclaimed water is provided from the Ralph W. Chapman Water Recycling Facility (RCWRF). The RCWRF has a ].3 million gallon per day (mgd) output of which an average of 0.67 mgd was used in ] 994. The RCWRF will be able to provide all of the reclaimed water necessary for SPA One. If additional reclaimed water is necessary for any reason, potable water will be used to supplement the available reclaimed water supply Raw water might also be used when the County Water Authority (CW A) completes conversion of Pipeline #3 from filtered potable water to raw water. This is scheduled to be completed in 1996/97. Initially SPA One will be served from the Reclaimed Pressure Zone 950. Ultimately, SPA One will be served from Pressure Zone 700. Zone 700 currently has no facilities and reclaimed water in this zone will not be available until the South Bay Water Reclamation Plant is on line. That plant is scheduled to be in operation in the year 200 I. PLANNING COMMISSION INFORMATIONAL MEMOMORANDUM August 30, 1995 TO: Chairman Tuchscher and Members of the Planning Commission FROM: Otay Ranch Project Team SUBJECT: Master Drainage Plan for Otay Ranch SPA One Action Requested: Review and discuss the Master Drainage Plan (MDP) and direct staff to make changes, if necessary. Background: A MDP is required by the Otay Ranch General Development Plan/Subregional Plan (GDP/SAP) for each Otay Ranch village at the SPA level of planning. The plan is required to address the adequacy of drainage facilities and improvements necessary to meet City criteria. The plan includes proposed facilities and methods to accomplish the following: a) Reduce the post development 100 year runoff from the site to a level equal to or less than that which occurred prior to development of the SPA. b) Address methods to reduce siltation and comply with the National Pollutant Discharge Elimination System (NPDES) as implemented by the Regional Water Quality Control Board (RWQCB). Existing Conditions: SPA One is within two drainage basins. The northerly portion of the SPA is within the Telegraph Canyon Drainage Basin (TCDB), and the southerly portion of the SPA is within the Poggi Canyon Drainage Basin (PCDB). Telegraph Canyon Creek is improved from the upper end of the basin in EastLake to 1-805. The entire length of the channel within SPA One is improved with an open vegetated channel which was designed to convey the 100-year runoff. There are two existing detention basins upstream of the project. These facilities were considered in the modeling performed for the MDP The segment west of 1-805, just east of Fourth Avenue, is unimproved. The City and Corps of Engineers completed channel improvements from Fourth Avenue to San Diego Bay. The unimproved segment is currently in the preliminary design stage to determine what can be constructed within the area to accommodate the 100-year flow. Planning Commission August 30, 1995 Page 2 Poggi Canyon Creek is in its natural state within SPA One. The drainage basin under consideration constitutes the upper two thirds of the entire basin. Downstream of SPA One, Poggi Canyon Creek is natural as it crosses the Sunbow parcel. Near Bmndywine Avenue, the flow is conveyed in an underground conduit system until (TO BE COMPLETED) Methodology: Drainage runoff quantities were calculated using the HEC-l computer program utilizing the kinematic wave model. This methodology was used in order to compare the results of previous studies for the TCDB. Detention basins were modeled and analyzed using the Pond-2 software from Haestad Methods. The computer runs have not been included in your packet because they do not provide information that can be evaluated unless trained in the modeling process. Mr. Glen Van Peski of Hunsaker & Associates (H&A) will be at the workshop to address any questions you might have concerning the processes used to determine runoff quantities or evaluate detention facilities. Comparisons To Previous Reports: Table 3 on page 19 of the MDP indicates that the peak flows are lower than peak flows determined by previous studies. Staff, in reviewing the results, questioned why the peak was significantly lower than the previous studies done by Leedshill- Herkenhoff (L-H),the Corps of Engineers (COE) and Rick Engineering (RICK). This concerned staff because the detention facilities would be reduced in size/capacity from facilities designed to detain higher peak flows. H&A indicated that they had found an error in the data input for the model run by L-H and RICK (Rick used the L-H data and modified it to include detention facilities so the error was also in the RICK calculations). The HEC-l Model requires an input of the amount ofrain which will occur in a given period oftime. L-H used the rainfall for a 100-year storm with a six-hour duration just as H&A did in their computer run except their run had the same quantity of water falling over a three-hour time frame instead of six-hour time frame. Intensity of rainfall is measured in inches per hour. By reducing the time the amount of rainfall was considered, the resulting peak flows were increased. Hunsaker & Associates was required to provide more proof to staff that the error had actually impacted the results. H&A ran additional computer runs to address our concerns and to prove that the error had occurred. After reviewing the information submitted and comparing the peak flows to those calculated by the COE, staff accepted the lower runoff quantities. Appendix "H" (less the computer runs) and Appendix "I" have been included in your packet for further information concerning how the lower peak flows were determined to be reasonable. Impacts of the Project: Grading and development of SPA One will result in an increase in the volume of runoff and the peak flows. In addition, the grading will result in some diversion of flow from one basin into another. As indicated on page 8 of the MDP, 0.18 square miles (115 acres) of the TCDB will be directed toward the PCDB and 0.03 square miles (sq. mi.) of the Wolf Canyon Basin (WCB) will also be directed into the PCDB. Total area diverted into the PCDB is 0.21 sq. mi. or, approximately, 134 acres. Planning Commission August 30, 1995 Page 3 The effects of development on runoff and peak flows is indicated on page 13 of the MDP. The project will increase the runoff volume by 9 percent in the Telegraph Canyon Basin (TCB) and 18 percent in the Poggi Canyon Basin (PCB). Peak flows will be increased 8 percent in the TCB and 25 percent in the PCB. The peak flows will be mitigated through the construction of detention facilities in the locations shown on Figure 5 of the MDP. The effects associated with the detention facilities is summarized on page 21 in Table 4. The detention facility will reduce the peak flows to 95 percent of the existing flow in the TCB and to 86 percent of the existing flow in the PCB. Retention will reduce the peak flow, but the total volume of water will not be reduced. This means that water will flow in Poggi Canyon and Telegraph Canyon Creeks for a longer period of time. Since the peak flow will be reduced, any flooding which might have occurred prior to development of SPA One will not be worsened by development. The longer flow time is of concern to the City in Telegraph Canyon Creek because there are flap gates on the outlet of drain pipes in the Woodlawn area which remain closed or partially closed when water runs deep enough in the channel to submerge the gate. This results in water backing up in the local basin during times of high flows. Since SPA One is not increasing the peak flow, staff does not consider the flap gate situation something which is the responsibility of this development. SPA One will be paying Telegraph Canyon Drainage fees that are to be used to correct downstream difficiencies. The City will look into ways to improve the function of the flap gates as part of that fee program. Further Analysis: At such time as the grading and improvement plans are submitted to the City for review, staff will require on-site drainage calculations to determine the drainage facilities necessary to convey the runoff from the development into the major drainage channels. At that time, staff will review the MDP and determine if adjustments need to be made as a result of the actual work being accomplished. Compliance With Flood Plain Regulations: SPA One does not propose to construct any structures within the Federal Emergency Management Agency (FEMA) designated floodways. However, the detention facility in Telegraph Canyon Creek and the grading and detention facility in Poggi Canyon Creek will impact the base flood elevations in the creeks determined by FEMA. This requires a Letter of Map Revision (LOMR) to be processed. The requirement to obtain a LOMR will be placed on the project as a condition of tentative map approval. Best Management Practices (BMP) Many of the BMP's have been required of developers by the City for many years. Those items an> as follows: . Landscaping and irrigation on all manufactured slopes. Once the landscaping is established, the amount of siltation which occurs is equal to or less than what happened prior to development. Planning Commission August 30, 1995 Page 4 . Construction of on-site detention/desilting basins to retain siltation at various locations within the project. . Sandbagging around drainage inlets to trap silt before entering the drainage system and ultimately be deposited into the main channel. . Sandbagging within the graded streets at designated intervals to slow down the flow of water and to trap silt behind the sandbags. . Silt fences are often required at the toe of slopes to trap silt which is washed off the slope during winter rains or from irrigation. . Dust control is required during the construction phase of the project. . Developers are informed with a certificate on the grading plans that a NPDES permit is required from the RWQCB This permit is granted and enforced by the RWQCB. The permit includes many of the items mentioned above and others that are mentioned in the MOP. . The City has a street sweeping program which is a post construction BMP.

DOC MEMORANDUM August 30, 1995 TO: Chairman Tuchscher and Members of the Planning Commission FROM: Otay Ranch Project Team SUBJECT: SPA One Parks Master Plan Action Request: Review and comment on the Parks Master Plan for SPA One. Background: The Otay Ranch GDP requires the preparation of a Parks Master Plan for each SPA. The SPA One Parks, Recreation, Open Space and Trails Master Plan is The Baldwin Company's proposal to satisfies the GDP requirements. The Plan presents the Otay Ranch Park System with its recreation facility requirements including plans for open space, trails, and community gardens in SPA One. Phasing, funding and maintenance are also part of the Plan. The Plan's proposals are different than the standard City parks and open space requirements. The proposals have been reviewed extensively by the Technical Committee and unresolved issues taken to the City Manager's Policy Committee for direction. Based on the Policy Committee's direction, Baldwin has developed two alternatives for park plans in SPA One. Alternative A represents the park plan based on the direction of the Policy Committee and Alternative B is Baldwin proposal for parks in SP A One. The SPA One Parks Master Plan is based on Alternative B. Concerns Raised: 1. Location, size, credit and maintenance of Pedestrian Parks 2. Deferment of Community Park 3. Private ownership of and credit for Town Squares 4. Timing of park needs analysis 5. Recreation facilities in each type of park 6. Community gardens maintenance and credit Resolution Of Concerns: 1. The City Manager Policy Committee determined that the smallest creditable park maintained through the General Fund will be the 2.0-acre park in Village 5. The Baldwin Company has proposed that they receive credit for the pedestrian parks and that these parks be maintained by assessment district. 2. The GDP anticipates deficits and surpluses in community parks as the Otay Ranch develops. Community parks are located in Villages 2, 10 and the EUC. A phasing PCPKRPT.DOC Planning Commission August 30, 1995 Page 2 schedule for neighborhood and community parks is provided on page 77 of the Parks Master Plan. 3. The GDP provides for credit and private ownership of the Town Square by business associations or districts. 4. The Master Plan proposes that park needs analysis be conducted in accordance with the City Landscape Manual just prior to the development of the parks in SPA One. 5 The needs analysis will assist in determining the type of recreation facilities to locate in each park. The GDP provides guidelines on the number of recreation facilities required by population in each SPA. 6. The GDP suggests community garden opportunities be provided within each village. The Subdivision Map Act permits park credit for community gardens. PCPKRPTDOC PLANNING COMMISSION INFORMATIONAL MEMORANDUM August 30, 1995 TO: Chairman T uchscher and Members of the Planning Conunission FROM: Otay Ranch Project Team SUBJECT: Regional Facilities Report Action Requested: Review and comment on the Regional Facilities Report for SPA One. Background: The Otay Ranch General Development Plan/Subregional Plan (GDP/SRP) requires that SPA applications be accompanied by a Regional Facility Report. This report identifies the forecasted demand for regional fucilities generated by development of the SPA One plan and addresses how that demand will be satisfied. The regional fucilities considered in this report, as required by the GDP, are Integrated Solid Waste Management, Arts and Cultural Facilities, Child Care Facilities, Health and Medical Services and Facilities, Hospitals, Mental Health Facilities, Community Clinics, Nursing Facilities, Community Health, Education, Screening, and Research Organizations, Medical Practitioncrs, Community and Regional Purpose Facilities, Social and Senior Services, Correctional Facilities, Justice Facilities and Cemetery Facilities. Concerns Raised: The following concerns emerged after the Regional Facility Report was circulated for comment. The points below were raised by the Area Conunission on Aging. No other department or conunission felt a need to respond to this document. I. Provision of areas for Churches 2. Provision of Mental Health Services are not the closest or accessible 3. Provision of Hospital service 4. Provision of Senior Facilities Resolution Of Concerns: I. Over 26 acres are identified within SPA One for Community Purpose Facility (CPF) uses. Churches are an appropriate use for this CPF land. 2. The fullowing Mental Health Services arc outside the City of Chula Vista boundaries but include the City within their service areas: a. Paradise Valley Hospital is not located in Chula Vista but docs serve the entire South County area. b. Vista Hill Hospital currently provides out-patient services in South County through Vista Hill Behavioral Center. 3. The Otay Ranch Facility hnplementation Plan and SPA One Regional Faci1ity Report concludes that SPA One residents will be served by Sharp-Chula Vista Medical Center located west of the project. Office space for lease or purchase will be available within the village core areas for health providers. 4. 26.2 acres of CPF land are included in the SPA One land use plan. This acreage is available to non-profit social service agencies. In addition, a 2,500 sq. ft. village multi-use cultural arts facility is planned within the Village One Village Core Park. This fucility will include community meeting space and related recreational uses such as classes and indoor recreation.

Health and Medical Services and Facilities: Although there is a demand for increased clinic services, funding has not been made availablc by governmental or other sources to expand this service. Should public or private funding become available, cornmunity elinics could be located in the CPF wne. 3. Cornmunitv and Regional Purpose Facilities: A requirement of the Otay Ranch GDP/SRP calls for thc provision of Community Purpose Facility land within the first phasc of development to satisfy the Telegraph Canyon Estates Speeific Plan requirements. 4. Justice Facilities: Should the region enact regional impact fees to assist in the funding of these facilities, SPA Onc development would be obligated to equitable participation It is further noted that additional analysis would be nccded as part of the EVC SPA. RGNLFAC2.DOC MEMORANDUM August 30, 1995 TO: Chairman Tuchscher and Members of the Planning Commission FROM: Otay Ranch Project Team SUBJECT: Annexation Action Request: Receive the comprehensive annexation of Planning Areas 1 and 3 of the Sphere Update Study and the Otay Ranch House property. Background: Annexations are initiated at Local Agency Formation Commission (LAFCO) by either voter/landowner petition or resolution of the City Council. The City Council has approved a resolution to petition LAFCO for the annexation of the Otay Ranch Annexation No. 1 and directed staff to submit an annexation application for Planning Areas 1 and 3 of the Sphere Study and the Otay Ranch House property. The Sphere Study and annexation application can then run concurrently, thereby saving processing time and costs for all parties. In order to expedite the annexation of the first Sectional Planing Area (SPA) of the Otay Ranch for Villages One and Five to the City, staff recommended City Council direct staff to file a resolution of petition with LAFCO. This filing will begin LAFCO processing of the annexation request. The City's application for annexation will not be considered complete by LAFCO until the SPA One EIR has been certified by the City Council and submitted to LAFCO. It is anticipated that the EIR will be subrnitted to the City Council for consideration in December, 1995. The SPA One EIR addresses the environmental impacts of the City annexing Planning Areas 1 and 3 and the Otay Ranch House property. The SPA One EIR is being prepared as part of the public review and hearings on SPA One this fall. Since LAFCO is the approval authority for the annexation and the City is the applicant, the Council can direct the application be filed without the EIR in final form. Under the CorteselKnox Local Government Reorganization Act of 1985 (GCS 5600, et. seq.), an annexation can be initiated by either the property owner or the City. In this instance, The Baldwin Company is primarily interested in annexing only SPA One: Villages One and Five. City staff believes additional territory is necessary for proper planning and future extension of City services to serve the entire Otay Valley Parcel. Therefore, staff recommended that Planning Areas 1 and 3 from the Sphere of Influence . Study, including the entire Otay Valley Parcel, the Inverted "L" and the non-Baldwin owned properties, be annexed along with the Otay Ranch House property (Figure 3). Planning Area One - The Otay Valley Planning Area is the largest of the Planning Areas encompassing approximately 9,300 acres. This area is surrounded on the west, north and PCANNRPT.DOC Planning Commission August 30, 1995 Page 2 east by the City of Chula Vista and is bounded by Telegraph Canyon Road on the north, Heritage Road on the west, the southern slopes of Otay Valley on the south and Lower Otay Reservoir on the east. The Otay River Valley comprises the southern boundary of and is wholly included within the Planning Area. ' There are several parcels that are not part of the Otay Ranch included within this Planning Area. These parcels range in size from approximately 9 acres to 250 acres and include the Nelson/Sloane rock quarry, the Otay Water District land dedicated for future reservoirs, the existing City of San Diego reservoir, a County landfill and several privately-owned properties Planning Area Three - Planning Area 3 is approximately 457 acres in size. This area includes the Inverted "L" Parcel of the Otay Ranch, the Watson property and the two smaller Clarkson and Turner parcels All of these parcels are part of the Sphere Study These properties are adjacent northeast of the Salt Creek Ranch project and, due to topography, relate more to the existing City limits than to Proctor Valley. Annexation of this area represents logical extension of City services. The Ranch House Property - The Ranch House property is approximately 132 acres in size and owned by the Steven and Mary Patrick Birch Foundation. The area surrounding the Ranch House is designated within the Otay Ranch General Development Plan (GDP) as Special Conference Center and Low Density Residential. The Ranch House area is within the City's existing Sphere of Influence. The existing Ranch House complex is surrounded by the City on two sides and needs to receive sewer service.

Background: Certain parcels located within Planning Area 1 and Planning Area 3 of the Sphere of Influence are not owned by the Baldwin Company and not a part of the Otay Ranch project. These "out-parcels" are noted on the attached map and ownership list. Prior to annexation to the City, LAFCO requires that these parcels be covered by the City's General Plan and be "pre- zoned". While the parcels are currently covered by the General Plan, the pre-zoning is being carried out concurrently with the annexation. Most of the out-parcels will be pre-zoned "Planned Community"; however, there are exceptions to this which are noted below. Following is a brief discussion of the parcels in question and their proposed pre-zone designation. Planned Community (PC) Zone: The primary purpose of the Planned Community Zone is to provide for orderly planning and long-term development oflarge tracts ofland in order to provide an environment of stable and desirable character, provide the developer with reasonable assurances that sectional development plans will be acceptable to the City, and to enable the City to adopt measures providing for the development of the surrounding areas compatible with the Planned Community Zone. Implementation of the PC Zone is currently restricted to parcels of land under unified ownership and 50 acres or more. An amendment to the PC Zone is currently under review by the Planning Department which would allow these parcels under 50 acres in size to be zoned PC. In order to develop, the property owners would have to propose an amendment to the Otay Ranch General Development Plan (GDP). If the property owner decided they did not want to be part of the GDP, they would then legally be entitled to the underlying permitted land use of A-8 (Agricultural). As can be seen from the list below, many of the individual out-parcels are less than 50 acres in sIze. EastLake Land Swap: Three parcels of approximately 161 acres, located adjacent to the southwest corner of the EastLake Greens Community. This area is part of the EastLake General Development Plan. Dauz Parcel: Adjacent to Telegraph Canyon Road within Otay Ranch SPA One and consisting of approximately 7.82 acres. Gorman Parcel: Located directly east of the Dauz Parcel and consisting of 1.82 acres. Planning Commission August 30, 1995 Page 2 Ross Parcel: Located along the future extension of Palomar Street and west of Paseo Ranchero and consisting of approximately 10 acres. Gerhardt Parcel: Two parcels located on Palomar Road and surrounded by Otay Ranch on three sides and Sunbow on the west consisting of 11.89 acres. Watson Parcel: Located in Planning Area 3 between the Inverted "L" and Salt Creek Ranch and consisting of 160 acres. Clarkson Parcel: Surrounded by Otay Ranch and Salt Creek in Planning Area 3 and consisting of 7.5 acres. Turner Parcel: Located in Planning Area 3 as part of the Inverted "L" and consisting of 1 0 acres Public/Quasi-Public (P/Q-P) Zone: In order to accommodate existing public uses which are located on some of the out-parcels, particularly the existing landfill operation, the Public/Quasi- Public Zone is being proposed. The amendment to the Zoning Ordinance to add this zone will be heard by the Planning Commission concurrently with the SPA One public hearings. The P/Q-P Zone would allow the landfill operation as a matter of right in order to allow the County- operated landfill to continue its operations without any additional permitting from the City. Closure of the landfill would be regulated by the appropriate State and Federal agencies. Subsequent uses such as golf courses and parks will be allowed as permitted uses. The following parcels will be pre-zoned P/Q-P: Citv of San Diego Water Reservoir: The existing water storage facility is situated on 19.59 acres and will eventually be surrounded by Village Eight, which will be reviewed in a future SPA. Water reservoirs are proposed as a permitted use in the P/Q-P Zone in order to allow the continued smooth operation of the reservoir. Otav Water District Parcel: The existing water storage facility is situated on 61 acres south of Telegraph Canyon Road, west of the proposed SR125. Water reservoirs are proposed as a permitted use in the P/Q-P Zone in order to allow the continued smooth operation of the reservoir. Otav Landfill: The existing landfill is located on 250.59 acres and is surrounded on three sides by the Otay Ranch Property (Villages Two and Three). Under the proposed P/Q-P Zone, the landfill would be a permitted use, but subject to performance standards. Agriculture (A-8) Zone: The final parcel requiring pre-zoning is the existing Nelson/Sloan Rock Quarry located on 136.7 acres on the north side ofOtay Valley Road and on the east side of Rock Mountain Road. The existing use permit would be grandfathered into the City.

Background: The Otay Ranch GDP sets out street cross-sections for the development of the streets within the Otay Ranch. Refinements to the street sections are proposed in SPA One to meet the specific requirements of Villages One and Five. The proposed design is consistent with and implements the GDP policies. The design reflects modifications proposed by the Otay Ranch Technical Committee. The Committee is comprised of members of the Project Team, Planning, Engineering, Parks and Fire Departments. Representatives of the Metropolitan Transit Development Board were involved in the transit alignment discussions which effects the street design. The traffic study indicates that all streets will operate within GDP mobility policies. SPA One street sections are found on pages 1-71 to 1-82 of the SPA One text. The GDP street sections are attached for your convenience. Concerns Raised: 1. The GDP shows transit right-of-way on side of Transit Village Entry Streets 2. Uplifting of curbs, gutters and sidewalks adjacent to parkway with trees 3. Residential street parkways with trees 4. Maintenance and appearance of all parkways Resolution Of Concerns: 1. After extensive discussions on the transit alignment with MTDB, the Technical Committee recommends that the transit run in the median of the Village Entry Streets. 2. Parkways on all streets with trees have been planned for a minimum width of 8 feet with root barriers. 3 Due to the requirement for 8-foot wide parkways, The Baldwin Company has limited the application of parkways on residential street to just one street segment in Village 1. All other residential streets will have monolithic sidewalks. 4. Common maintenance of all parkways is needed to ensure acceptable appearance. Since homeowners associations are not proposed by Baldwin, maintenance is proposed to be provided by landscape maintenance districts. Planning Commission August 30, 1995 Page 2 Future Issues: I. Project Team: Parkways with trees have been identified as a major element of a pedestrian friendly street environment. The Project Team planners believes the issues should be explored further to find an acceptable design solution to provide 5-foot parkways with trees on residential streets.

Background: The traffic studies were accomplished after receIving direction from the transportation technical subcommittee on the assumptions, methodology and scope of the analysis. The technical subcommittee consisted of representatives from the Otay Ranch Project Team, SANDAG, CalTrans, California Transit Ventures (CTV) MTDB, the County of San Diego, Urban Systems, Baldwin, Cotton/Beland (EIR Consultant), and BRW (traffic consultants for Cotton/Beland). The traffic and phasing analysis has been reviewed by staff and subcommittee members. Comments and revisions as a result of that review are being incorporated into the documents but are not included in the documents in your packet. Methodologies: The traffic studies were based upon the San Diego Association of Governments (SANDAG) Series 8 traffic model. This process assumes trip generation rates of 7.6 trips per single-family dwelling unit (SFD) and 6.4 trips per multi-family dwelling unit (MFD). These rates are lower than previous studies which used 10 trips/SFD and 8 trips/MFD. The lower trip rates for residential land uses reflect the most recent model enhancement completed by SANDAG. The entire transportation modeling process was enhanced during the transition from Series 7 (Year 2000) to Series 8 (year 2015). One of the primary improvements to the previous modeling process was the ability of the new Series 8 model to incorporate the adopted General Plan level information for each jurisdiction within the County of San Diego. This enhanced computing capability resulted in Series 8 projections using 4,545 Traffic Analysis Zones (TAZs) compared to 773 T AZs used in Series 7 forecasts. Scope of Analysis: The analysis was based on a fixed level trip generation trom proposed Otay Ranch SPA One Project and a set of assumed trip activity from cumulative development projects in eastern Chula Vista. This cumulative development traffic activity level was utilized to develop a series of traffic projections evaluating four separate network alternatives. The four alternatives are: . No Project (Alternative 0) . The Proposed Project . Alternative 1 (Otay Lakes Road Connection) . Alternative 2 (Interim SR-125) Planning Commission August 30, 1995 Page 2 The study analyzed the four alternatives for impacts to the following: . On-Site Circulation System . Study Area Freeway Segments . Study Area Arterial Segments . Study Area Intersection Capacity (49 analyzed) . Study Area Freeway Interchange/Capacity . Transit Operations . Bicycle/Pedestrian Facilities . Trip ReductionlLand Use Design Assessment . Congestion Management Plan (CMP) Conformance The analysis were performed for three assessment time frames: . Existing Conditions (1995) . Interim Conditions (SPA One Buildout Year 2010) . Full Southbay Buildout, including SPA One In addition to analyzing the four network alternatives, a phasing analysis was performed for the years 2000, 2005 and 2010. This analysis was performed to highlight the impacts of SPA One and to determine what mitigation will be necessary to maintain acceptable peak hour traffic conditions with the development. This cumulative analysis included only those developments within the City of Chula Vista with approved Tentative Maps and background growth in the Southbay region. The on-site transportation system was also analyzed to determine if additional access points were necessary in order to meet City threshold standards. The analysis indicated that the on-site system will work without a third access point. However, safety issues were raised by the Engineering and Fire Departments and the Policy Committee has required a third access be provided for each village. Significant Issues: Section 6.5 of the traffic analysis shows a comparative evaluation of impacted streets within the City and County. As indicated in the section, many streets operate below the level of service (LOS) considered acceptable by the City or the County with buildout conditions for SPA One in the year 2010 The study also revealed that the majority of these impacts occur with or without the project. This is significant because it raises the question as to what improvements SPA One should provide to mitigate impacts of the project. The phasing analysis was conducted to attempt to segregate SPA One impacts from other anticipated development impacts and to identify the timing for implementing key circulation improvement projects. Planning Commission August 30, 1995 Page 3 A number of the road segments indicated to be below acceptable LOS have a small percentage of segment traffic contributed by SPA One. Staff would like to point out that the City had meetings in 1989 with the County staff where an apparent agreement was reached as to which roadways in the Bonita area would be City responsibility and which would be County responsibility. As a result of those meetings, the City's Transportation Development Impact Fee program (TDIP) was amended to include roads within the County. One of those projects has been constructed (Central Avenue widening to 3 lanes at a cost of $190,000). The City has contributed $50,000 toward design of another County street improvement project. The County has subsequently put on hold key projects in the Bonita area or dropped them as a result of public pressure. Total estimated cost of County roads included in our current TDIP is approximately 3 million dollars with an additional 8.7 million dollars included in the SR-125 DIP to upgrade Proctor Valley Road, Sweetwater Road and partial funding of San Miguel Road to provide an interim facility. Mitigation Required of SPA One: Section 9 of the traffic analysis for SPA One indicates which roadway segments and/or signalized intersections are to be mitigated. Staff has indicated to BRW that the analysis must limit the mitigation requirements to a point where the mitigation can be justified by the impact of the project (nexus). Requiring full mitigation when the project contributes 2 percent of the total traffic can not be justified. SANDAG requires compliance with the Congestion Management Program (CMP) for large projects to evaluate impacts to the regional transportation system. Guidelines for the (CMP) use 50 or more peak hour trips in one direction on an arterial as the criteria to determine when a street segment will be examined in the Transportation Impact Report (TIR). This program is used to determine impacts to the Regionally Significant Arterial (RSA) system. Staff proposes to use the CMP criteria to determine at which point mitigation will be considered as a requirement for SPA One development. Peak hour trips are 10 percent of the Average Daily Trips (ADT) and peak one-way trips are 60 percent of the peak hour trips. This means that a street will be considered insignificantly impacted, requiring no mitigation, if the project contribution to the segment ADT is less than (50/ 0.6)xl0 or approximately 800 ADT. Impacts to DIP streets will be mitigated through construction of DIP improvements or payment of DIP fees. Impact from SPA One to Bonita area road segments is considered by staff to be mitigated by participation in the DIP programs. Staff feels that impacts to Bonita streets (by City projects) have been addressed by including County streets in both the TDIP and the SR-125 DIP as indicated above. Traffic signals are also proposed to be installed as mitigation for development of SPA One. Installation of those facilities will be provided as required by the EIR with credit given toward Traffic Signal Fees in accordance with City policy. WORD\WAU\PLANCOMT.DOC
