SUBMITTED BY: DIltECTOR OF P C REVIEWED BY: CITY MANAG ASSISTANT CITY ANAGER ~j~ 4/STHS VOTE: YES ® NO ^ SUMMARY The Poggi Canyon Gravity Sewer Basin Development Impact Fee (DIF) was established on November 25, 1997 to facilitate construction of the Poggi Canyon trunk sewer, which was needed to serve properties within the Poggi Canyon Basin. Council will consider the approval of the first update to the Poggi DIF since its inception, which recommends that the Poggi Canyon Sewer Basin DIF be reduced from $400 to $265 per Equivalent Dwelling Unit (EDU). The public hearing has been duly noticed. ENVIRONMENTAL REVIEW The Environmental Review Coordinator has reviewed the proposed activity for compliance with the California Environmental Quality Act (CEQA) and has determined that the activity is not a "Project" as defined under Section 15378 (b)(4) [Creation of government funding mechanisms] of the State CEQA Guidelines because it does not involve a physical change to the environment. Any future proposed facility construction will require appropriate environmental review and determination. Therefore, pursuant to Section 15060(c)(3) of the State CEQA Guidelines this activity is not subject to CEQA, thus, no environmental review is necessary. 6-1 6/16/09, Item Page 2 of 8 RECOMMENDATION 1. Adopt the resolution accepting the Poggi Canyon Basin Gravity Sewer DIF update report. 2. Conduct the public hearing. 3. Adopt the ordinance amending Ordinance No. 2716. BOARDS/COMMISSION RECOMMENDATION Not applicable. DISCUSSION Background This discussion represents a brief summary of more detailed information contained in the attached report titled "Poggi Canyon Basin Gravity Sewer Development Impact Fee Update" dated Apri12009 (Attachment 1). On November 25, 1997, Council adopted the Poggi Canyon Gravity Sewer Basin Plan by Resolution 18824. The basin plan, prepared by Wilson Engineering, accomplished the following: a) defined the benefit area (see Exhibit A); b) identified the alignment and sizes of the pipeline that would be needed to serve the benefited properties; c) developed an estimate for the construction of the required facilities; and d) developed an estimate of the fee that would be charged, based on the fair share apportionment of costs, for each benefited dwelling unit. At that same meeting, Council adopted Ordinance No. 2716 establishing the Poggi Canyon Sewer Basin Development Impact Fee at $400 per equivalent dwelling unit (EDU) to fund the construction of the Poggi Canyon Trunk Sewer. In the original 1997 basin plan, the proposed Poggi Canyon trunk sewer was broken into reaches numbered 201 - 221. The reaches delineated areas with significant inflows into the system from major projects, changes in pipe diameter, or significant changes in grade. As certain adjacent tributary properties had been developed prior to the imposition of the Poggi Development Impact Fees, their fair share was not collected; thus, the deficiency would be considered a City obligation as new development cannot be required to pay for existing deficiencies. Reaches 201 - 204, 206, and 207 were considered City obligations for this reason. Reaches 205 and 208 - 221 were considered DIF obligations since they were needed to serve new development. Since establishing the Poggi DIF, all reaches of the Poggi Canyon trunk sewer as defined in the original basin plan have been constructed. However, through additional studies completed since 1997, other facilities have been identified that will be needed to facilitate future development within the basin. Therefore, it is now necessary to update the DIF to include these additional improvements in the list of D1F eligible facilities. The update will also ensure that a) fees are fairly and equitably distributed among the remaining properties within the benefit area; b) sufficient finding is available to complete the required improvements; and c) updated fund balance and land use projections are reflected in the program. 6-2 6/16/09, Item Page 3 of 8 To accomplish these tasks, the City retained Pacific Municipal Consultants (PMC) to prepare all necessary analysis and documentation in support of an impact fee program meeting the requirements of Government Code §§66000 et seq. See Attachment 1 for the DIF Update Report. Current Fee The 1997 cost estimate for constructing the Poggi Canyon trunk sewer (including soft costs for design, inspection, DIF administration, and contingencies) was expected to total approximately 56.1 million. The portion of the costs that were considered City obligations was estimated to total approximately $1.7 million. The remaining estimated construction cost of approximately $4.4 million for reaches 205 and 208 - 221 was spread among the 10,917 benefited EDUs within the basin resulting in a fee of $400/EDU. Therefore, on November 25, 1997 Council adopted Ordinance 2716, establishing the Poggi Canyon Gravity Sewer Basin DIF at $400 per EDU. Fortunately, the actual cost of the Poggi Canyon trunk sewer segments (including soft costs) included in the original DIF was significantly less than what had been anticipated in 1997. The savings were primarily the result of designing and constructing the sewer concurrent with the above-ground surface improvements. These savings are summarized below in Table 1. Table 1 Summary of Cost Savings for Originally Anticipated Facilities Description DIF Obligation City Obligation Total 1997 "Wilson Study" Construction Cost Estimate $ 3,048,000 $ 1,230,000 $ 4,278,000 1997 "Wilson Study" Soft Costs $ 1,328,544 $ 526,440 $ 1,854,984 Subtotal $ 4,376,544 $ 1,756,440 $ 6,132,984 Actual Total Cost of Facilities $ 2,905,999 $ 1,046,032 $ 3,952,031 Savings $ 1,470,545 $ 710,408 $ 2,180,953 Current Proiect Status Since 1997, all reaches of the Poggi Canyon trunk sewer inchided in the original basin plan have been constructed. The last of the original DIF facilities, Reach 205, was constructed by the City in 2005. In addition to the facilities specifically identified in the Wilson Study, the report contemplated additional improvements (referred to as the Poggi Canyon Extension) that would be needed to serve the eastern edge of the basin located east of what is now SR-125. At the time, the alignment of SR-125 was unknown. Therefore, the Wilson Study recommended Chula Vista complete an alignment study in the future, identifying the exact location of the Poggi Canyon Extension, but did not account for the cost of this extension when determining the DIF fee. Once the ultimate alignment of the SR-125 was known, plans for the development of the land adjacent to the toll-road were developed, as was a plan to extend the Poggi Canyon trunk sewer. The sewer extension was to serve two functions: 1) the extension would provide a gravity sewer system to portions of the Eastlake Greens that were being served by a pump station and force- main diverting flows into the Telegraph Canyon sewer basin until the Poggi extension could be 6-3 6/16/09, Item ~!J Page 4 of 8 constructed and 2) the extension would provide sewer service to the Eastlake Land Swap subdivision located east of SR-125. The alignment of the extension to serve these projects is generally described as consisting of three segments. Starting from the SR-125, the extension heads easterly along Olympic Parkway and is commonly referred to as the "Poggi Extension in Olympic Parkway." From there, the extension turns to the northeast, splitting the Eastlake Land Swap commercial parcels, and is commonly referred to as `'Reach 2." Once the extension reaches Eastlake Parkway, it turns north to connect to existing facilities serving the Eastlake Greens subdivision. This final segment of the extension is commonly referred to as "Reach 1." (See Exhibit B for the location of each segment) Since the Wilson Study was completed, the Poggi Canyon Extension has been constructed in order to accommodate development within the basin. The Poggi DIF Update proposes to add two of the three facilities that make up the extension into the Poggi DIF program as described in more detail below. Po~¢i Canvon Extension Reach 1: Construction of Reach I, and the resulting decommissioning of a pump station, was completed in 2008. As previously approved by Council on April 27, 2004 via Resolution 2004-130, the cost associated with the construction of Reach I was to be funded by Community Facilities District (CFD) 06-I. As a result, this reach is no[ recommended for inclusion in the Poggi DIF program even though it is a part of the Poggi Canyon trunk sewer system. Poeei Canvon Extension Reach 2: When the Poggi Canyon Sewer Basin DIF was established in 1997, the Poggi Canyon Extension was expected to be a regional facility, serving a number of development projects including Eastlake Greens and Eastlake Land Swap parcels. After a thorough review of alignment alternatives, it was decided the best alignment was to construct Reach 2 of the extension through the Land Swap project. Due to the topography of the area, Reach 2 was constructed as a deep sewer facility, with portions of the pipe located up to 60' below ground. Due to its extremely deep alignment, and in an effort to coordinate its construction with that of the Land Swap parcel above it, the City entered into an agreement with The Eastlake Company that allowed them to construct the sewer segment and be reimbursed for construction costs. As approved by Council on April 27, 2004, via Resolution 2004-129, the reimbursement was to be funded by the Trunk Sewer Capital Reserve Fund. However, as a regional facility serving multiple properties within the Poggi Canyon Sewer Basin, the 2009 Poggi DIF Update proposes adding Reach 2 into the DIF program, and that the Poggi DIF reimburse the Trunk Sewer Fund for the cost of construction of the facility. If included, the total amount that would be reimbursed to the Trunk Sewer Fund would be $1,094,707. Poggi Canvon Extension in Olympic Parkwav: In addition to Reach 2, and as identified in the Eastlake/City reimbursement agreement, a short reach of sewer connecting the system in Olympic Parkway at SR-125 to Reach 2 was constructed by The Eastlake Company and financed via CFD 06-I. Located downstream of Reach 2, the Poggi Canyon Extension in Olympic Parkway also serves multiple properties within the Poggi Canyon Basin, and is therefore considered a regional facility. As such, the 2009 Poggi DIF Update recommends adding this facility to the Poggi DIF program. With the inclusion of this 6-4 6/16/09, Item Page 5 of 8 reach as a DIF eligible improvement, the City shall reimburse the CFD in the form of a reduction in the annual tax levy for the CFD using DIF funds in an amount equal to the construction costs for the facility which total $24,000. The Eastlake Company has already been reimbursed for the construction of this reach through CFD 06-I. In addition to the Poggi Canyon Extension Improvements, the DIF Update report recommends adding two additional improvements to the DIF program to serve the projected buildout of the basin. These improvements are briefly described below: Improvements 1 and 2 (as identified in the DIF Update Report) Based on updated land use information and current development strategies, approximately 1,400 feet of trunk sewer in Olympic Parkway, located immediately east and west of Brandywine Avenue, may require upsizing from 18-inch to 21-inch diameter pipe. The cost related to these two projects is estimated to be $916,300, and is proposed to be added to the DIF program as both improvements are considered regional facilities serving multiple properties within the benefit area. A summary of the proposed Poggi DIF facility costs is shown below in Table 2. Table 2 Summary of Proposed Poggi Canyon DIF Facility Costs Description DIF Obligation City Obligation Total Original Facilities (Actual Cost) $ 2,905,999 $ 1,046,032 $ 3,952,031 Poggi Canyon Extension (Actual Cost) $ 1,118,707 $ - $ 1,118,707 Additional Improvements 1 and 2 (Estimated $ 816,300 $ - $ 916,300 Cost) Total Cost of Facilities $ 4,941,006 $ 1,046,032 $ 5,987,038 Reimbursements As the Otay Ranch area developed, the developers of Otay Ranch Village 1, Village 1 West, and Village 5 constructed portions of the Poggi Canyon trunk sewer concurrently with the construction of Olympic Parkway, a key transportation link for Otay Ranch. According to Ordinance 2716, the City, at its option, may reimburse the developer from the DIF fund either in cash over time as fees are collected, or give a credit against the impact fee for the construction of eligible improvements. The developers, Otay Ranch Company and McMillin Company, were ultimately reimbursed for the cost of these facilities through CFD 99-1 and CFD 97-3, respectively. In addition, many of the merchant builders of these projects within the Poggi basin also paid DIF fees at the time of building permit issuance. Since the master developers (and subsequently the CFDs) originally financed the construction of the improvements and DIF fees were paid at time of building permit issuance, double payment for the construction of these facilities were made. It is recommended that the City recognize this overpayment and appropriately plan to reimburse current home owners, as required by Government Code Section 66001(e), for the excess payment to the extent that funds are available following the completion of all remaining improvements. 6-5 6/16/09, Item~l~ Page 6 of 8 In consideration of projects constructed by developers or other City funds, the Poggi DIF Update also proposes several other reimbursements be made. Construction of the originally anticipated facilities considered to be City obligations (reaches 201-204 and 206-207) was funded by the Trunk Sewer Capital Reserve Fund. $1.7M was transferred from the Trunk Sewer Capital Reserve Fund into the Poggi Canyon Sewer Fund. The actual cost of the City obligations was less than the dollar amount transferred from the Trunk Sewer Capital Reserve Fund. The remaining balance of $710,408 was transferred back to the Trunk Sewer Capital Reserve Fund; however, the interest earned on the full $1.7M while in the Poggi Canyon Sewer Fund has not yet been reimbursed to the reserve fund. The Poggi DIF Update recommends transferring the interest back to the Trunk Sewer Capital Reserve fund. As of June 30, 2008, the total amount of interest earned was $470,556. The amount of interest earned and returned to the reserve fund will depend upon the date the transfer is made. With the inclusion of Poggi Canyon Extension Reach 2 ($1,094,707) and the Poggi Canyon Extension in Olympic Parkway ($24,000) as eligible DIF facilities, reimbursements to the Trunk Sewer Capital Reserve Fund and to CFD 06-I respectively should be made for advancing the funds for construction of these reaches. Reimbursements would only be made once enough DIF fees are collected to fund the cost of the remaining improvements, or construction of the improvements has been guaranteed through developer exactions. Based on permit records the following refunds will need to be made: Table 3 Summary of Refunds Developer /Fund Development Refund Amount Otay Ranch Co Otay Ranch Village 1 $ 443,567 Otay Ranch Co Otay Ranch Village 5 $ 197,200 Otay Ranch Co Otay Ranch Village 1 West $ 204,000 McMillin McMillin Villages 1 and 5 $ 157,408 CFD 99-I $ 19,738 CFD 97-3 $ 283,858 CFD 06-I $ 24,000 Trunk Sewer Capital $ 470,556 Reserve Fund Tmnk Sewer Capital $ 1,094,707 Reserve Fund Total $2,895,034 With the exception of those amounts related to the CFDs, the final amounts shall be determined by the City upon written request for the refunds and submittal of documentation of payment by the merchant builder or current homeowner, as determined by the City Attorney. The City Attorney may also request a hold harmless agreement be entered into to protect the City from disputes arising from the refunds. 6-6 6/16/09, Item ~p Page 7 of 8 Fee Determination When the DIF was originally established the total cost of DIF program was spread amongst 10,917 benefited EDUs within the basin. The revised analysis provided in the DIF Update Report indicates that there will now be a total of 16,443 benefited EDUs at buildout. Of these, 11,433 have been permitted and/or constructed and 5,010 EDUs remain to pay the fee. As with most programs, there is a cost to administer, prepaze annual reports, oversee, and update the DIF program, as well as costs to monitor the facilities for the timing of improvements. The 2009 DIF Update, as was the case with the 1997 Wilson Study, includes a DIF administration component to cover these costs. The DIF Update includes $120,000 for future administration of the program and recommends the cost be added to the overall DIF program cost. The proposed fee assumes that collection of approximately $244,160 in DIF fees will not be realized as building permits for several parcels were issued without collecting the fee. These parcels include public facilities such as schools, parks and fire stations, as well as some residential parcels within Sunbow II. These uncollected fees, by law, may not be passed on to others. When capital improvement projects are created to construct the remaining DIF facilities, City staff will appropriate the necessary funding using appropriate sewer fund revenues to account for the $244,160 as needed. Accounting for the cost of future improvements needed within the basin, refunds, reimbursements, DIF administrative costs, etc., the Poggi DIF as proposed in this update needs to account for approximately $3,687,174 worth of expenditures. There are currently $2,361,786 available in the DIF fund, meaning the Poggi DIF must still collect $1,325,388. Spreading these expenditures across the remaining EDUs within the basin results in a new fee of $265/EDU ($135 less than the current fee). The reduction is primarily due to the following: a. A significant increase in the number of units within the basin to share the cost of the facilities. b. Cost savings realized through the coordinated construction of sewer improvements with above-ground improvements. Table 3, shown below, summarizes the calculation resulting in the proposed Poggi DIF Impact Fee of $265/EDU. Table 4 Poaai DIF Calculation Remaining Costs Remaining Improvements $ 916,300 Reimbursements $ 2,895,034 Administration $ 120,000 Subtotal $ 3,931,334 Less Unrealized Fees $ (244,160) Total Remaining Costs for Poggi DIF $ 3,687,174 Existing Poggi DIF Fund Balance $ 2,361,786 Total Funds Required $ 1,325,388 Number of EDU's Remaining 5,010 DIF Rate per EDU 6_~ $ 265 6/16/09, Item_(~ Page 8 of 8 Coordination with the Development Communit Historically, when updating development impact fees, City staff has met with the major developers affected by the change to review the methodology and findings of the report. In an effort to reduce the consultant and staff time involved in this process, City staff notified the major developers of the proposed Poggi D1F Update via e-mail and conventional mail. In the letter sent to each developer on May 11, 2009, staff directed developers to the City Wastewater Engineering website where the entire draft Poggi DIF Update could be viewed and/or downloaded, and asked them to submit comments or questions (if any) to staff electronically. No comments or questions were received. DECISION MAKER CONFLICT Staff has reviewed the property holdings of the City Council and has found a conflict exists, in that Councilmember McCann has property holdings within 500 feet of the boundaries of the property which is the subject of this action. CURRENT FISCAL IMPACT There will be no impact to the General Fund as a result of this Poggi DIF update. The costs associated with this Poggi DIF update have been funded utilizing the balance of funds in the Poggi Canyon Trunk Sewer Improvement Project (Reach 205 Upgrades - SW226). That project was funded with Poggi Canyon Basin DIF funds and it was the last remaining facility to be constructed based on the original basin plan; consequently, this update was begun as an extension of staff effort to closeout the project and update the basin plan. ONGOING FISCAL IMPACT Although the approval will result in a reduction of the fee, it is projected that at this new fee level, the remaining EDUs in the Basin will meet the outstanding DIF obligations. When capital improvement projects are created to construct the remaining DIF facilities, City staff will appropriate the necessary funding using appropriate sewer fund revenues to account for the uncollected $244,160 as needed. In addition, the proposed fee accounts for $120,000 for administration of the DIF program. As a result, there should be no ongoing impact to the general fund.

The Basin includes a signifcant portion of the O#ay Ranch general planning area situated north of the Wolf Canyon and Salt Creek Basins and south of the Telegraph Canyon Basin. Approximately 70% of the basin is built out. Figure 1 shows the general location of the basin. In 1997, Wilson Engineering prepared the Poggi Canyon Basin Gravify Sewer Basin Plan for the City of Chula Vista (attached as Appendix F). The 1997 Basin Plan detailed the trunk sewer improvements needed to increase the capacity of the trunk line and to facilitate buildout of the Poggi Canyon Basin. Based on the findings of the Basin Plan, Council adopted Ordinance No. 2716 (Appendix A) establishing the Poggi Canyon Sewer Basin Development Impact Fee (DIF) to finance the construction of trunk sewer improvements from Main Street, northeasterly to Olympic Parkway and easterly to SR 125 (Poggi Canyon Sewer InterceptorJ. All improvements that were included in the original study have been constructed. 1.2 PURPOSE The purpose of this report is to update the Development Impact Fee (DIF) established in 1997 pursuant to the provisions of California Government Code §§66000 et seq. The Update of the DIF is recommended for the following reasons: • To reflect the final construction cost of the Poggi Canyon Sewer Interceptor; • To add the upstream reach of trunk sewer main between SR 125 and Eastlake Parkway to the DIF program (Poggi Canyon Interceptor Extension (Reach 2); To update the Poggi Canyon Basin Equivalent Dwelling Units (EDUs) based on updated development projections and proposed diversions; To identify additional Poggi Canyon Interceptor improvements that may be needed to accommodate additional EDUs to the basin; and To adjust the fee based on the evaluation of the actual cost of facilities, future improvement costs, available revenues and number of remaining dwelling units. 1.3 RECOMMENDED DIF RATE The DIF rate is calculated based on the remaining cost of construction of the recommended improvements less the available funds and allocated to the remaining number of Equivalent Dwelling Units (EDUs) within the Poggi Canyon Sewer Basin benefiting from the facilities (Area of Benefit). Spreading the costs on an EDU basis allows for assigning the share of costs in an equitable manner to all land uses within the Area of Benefit. Based on final construction costs for the Poggi Canyon Sewer Interceptor, including the reach from SR 125 to Eastlake Parkway (not included in the 1997 Basin Plan) and future needs for build- out of the basin, the revenues remaining to be collected from future building permits equal $1,325,388.

The reduction in fees is partially offset by the need for additional improvements to serve the additional EDUs projected to be included in the basin based on updated development proposals.

Vicinityy MTa~pv MRE$ ~ Pyyyv ~/ CHAPTER 1 -EXECUTIVE SUMMARY 1.4 MITIGATION FEE ACi As a result of widespread imposition of public facilities fees, the State Legislature passed the Mitigation Fee Act, starting with Assembly Bill 1600 in 1988. The Act, contained in California Government Code Sections 66000 et seq., establishes ground rules for the imposition and ongoing administration of impact fee programs. The Act became law in January 1989 and requires local governments to document the following when adopting an impact fee: 1) Identify the purpose of the fee; 2) Identify the use of fee revenues; 3) Determine a reasonable relationship between the fee's use and the type of development paying the fee; 4) Determine a reasonable relationship between the need for the fee and the type of development paying the fee; and 5) Determine a reasonable relationship between the amount of the fee and the cost of the facility attributable to development paying the fee. In general, the fee cannot be more than the cost of the public facility needed to accommodate the development paying the fee, and fee revenues can only be used for their intended purposes. The Acf also has specific accounting and reporting requirements annually and every five years for the use of fee revenues. During the 2006 legislative session, the legislature passed and the Governor signed a measure that further defines the restrictions that a fee shall not include the costs attributable to "existing deficiencies." City of Chula Vsta Apri12009 61=~ 7 Poggi Basin Grevity Sewer Developmerrt Impact Fee CHAPTER 2 -INTRODUCTION 2.7 INTRODUCTION Wastewater generated within the Poggi Canyon basin is conveyed to the City of San Diego's Metropolitan Wastewater Department (Metro) sewerage system via the Poggi Canyon Interceptor, which generally follows Olympic Parkway to Brandywine Avenue and then extends southwesterly through open space easements and local roads connecting to the Salt Creek Interceptor in Main Street just west of Melrose Avenue. Flow from the Poggi Canyon and Salt Creek Sewer Basins continue westward in the Salt Creek Interceptor to a new metered connection to the South Metro Interceptor west of Interstate 5. Design criteria, including minimum pipe diameters and slopes, for the Poggi Canyon Interceptor was provided in the Poggi Canyon Basin Gravity Sewer Basin Plan (Wilson Engineering, 1997) (Basin Plan). The planning basis for that study included land use information from Tentative Maps for Otay Ranch Villages 1 and 5, the Otay Ranch SPA 1 Plan, the site utilization plan for Sunbow II and the General Development Plans for Otay Ranch and Eastlake. The Basin Plan estimated the total number of projected equivalent dwelling units (EDUs) within the Basin at buildout and identifed the sewer improvements required to serve future development. The Basin Plan utilized two different design criteria to size the facilities. Sizing of new or replacement sewer was based on 280 gallons per day (gpd) per EDU while analysis of the hydraulic capacity of existing sewer facilities was based on a generation rate of 265 gpd per EDU as specified in the City's current Subdivision Manual. The analysis in this study is based on a sewage generation rate of 265 gpd per single-family home. This study updates the number of equivalent dwelling units (EDUs) within the Poggi Canyon Sewer Basin based on information provided in the City's Major Project Development Status report dated July 2, 2007, City's Permit Plus database, Chula Vista Geographic Information System (GIS), Tentative Maps, Technical Sewer Studies and Final Maps. The 1997 Basin Plan provided a basis for the establishment of a Poggi Canyon Gravity Sewer DIF to fund construction of the Poggi Canyon Interceptor. The Interceptor was completed in three general phases: 1) Construction of a new sewer in easements behind Oleander and Melrose Avenues and in Otay Valley Road and Palm Avenue from the Sunbow II Development westward to a connection to the Date-Faivre Trunk Sewer near Otay River Valley. The sewer was subsequently connected to the Salt Creek Sewer in Main Street, just west of Melrose Drive; 2) Construction of a new sewer in Olympic Parkway from Brandywine Avenue easterly to SR 125; and 3) Improvement of the existing sewer beneath I-805 (Reach 205) just east of Talus Street. A fourth phase from SR 125 to Eastlake Parkway (not included in the 1997 Basin Plan) completed by Eastlake Company is recommended to be added to the DIF program. The construction was pre-funded by the Trunk Sewer Capital Reserve Fund pursuant to an agreement between Eastlake Company and the City. In addition, a portion of the sewer in Olympic Parkway, west of Brandywine was upsized to 21-inch diameter pipe in conjunction with aroad-widening project that relocated a segment of the sewer. This latter improvement was not funded by Poggi Canyon Basin Sewer Impact Fees.

The 1997 Basin Plan calculated a Development Impact Fee (DIF) based on the total estimated cost of construction of the recommended improvements spread over the total number of future EDUs within the Poggi Canyon Sewer Basin (with the City funding reaches 201 through 204 and reaches 206 through 207 for existing EDUs). In 1997, by Ordinance No. 2716, the fee was established at $400 per EDU based on the recommendations of the 1997 Basin Plan. Table 2-1 presents the DIF calculation for the existing fee of $400 per EDU.

Poggi Basin Gravity Sewer Development Impact Fee ~22~ City of Chula testa April 2009 6-21 CHAPTER 3 -BASIN DESCRIPTION 3.1 BASIN AREA The Poggi Canyon Sewer Basin extends southwesterly from the Eastlake Greens subdivision to the just north of the Otay River Valley, west of Interstate 805. The basin lies between the Telegraph Canyon Sewer Basin to the north and the Wolf Canyon and Salt Creek Sewer Basins to the south. The westernmost portion of the basin, generally to the west of Brandywine Avenue, includes residential development that existed prior to establishment of the fee program. To the east of Brandywine Avenue, the basin encompasses existing and planned development within the Sunbow II Sectional Planning Area, the Otay Ranch General Development Plan, and the Eastlake GDP. Figure 2 shows the sewer basin and development boundaries. Several major project developments, south of Olympic Parkway, are naturally tributary to one of three sewer basins, Poggi Canyon, Wolf Canyon and Salt Creek. Although both the Poggi Canyon and Satt Creek Tunk sewers have been constructed, Rock Mountain Road Sewer, which is required to serve the projects within the Wolf Canyon, Basin, has not been constructed. Consequently, some of the projects that are tributary to that basin (i.e. Village 7 and the Eastern Urban Center - EUC) have designed portions of their projects to sewer to either Poggi Canyon Basin or Salt Creek Basin on a temporary or permanent basis. Figure 2 identifies these areas. As a development condition to permanently divert flows into the Poggi Canyon Sewer Basin, the developer should be required to pay the Poggi Development Impact Fee for any diverted EDUs. One concern to be addressed when diverting flows is the capacity of the sewer accepting additional flows. This is addressed in Chapter 4. 3.2 SEWERAGE FACILITIES Major facilities that serve the Poggi Canyon Basin include the Poggi Canyon Interceptor identified in the 1997 Basin Plan and the reach of sewer from SR 125 to Eastlake Parkway (Poggi Canyon Interceptor Extension -Reach 2) as shown in Fgure 2. The 1997 Basin Plan included all of the reaches of the Poggi Canyon Interceptor (from the connection to the Dafe-Faivre Trunk Sewer eastward to SR-125.) Funding for construction of these reaches was included in the current Poggi Canyon Gravity sewer DIF. The Poggi Canyon Interceptor Extension -Reach 2, east of SR 125, was not addressed in the 1997 Basin Plan other than to indicate that there were design constraints for providing gravity sewer and eliminating the pump station. Eastlake Company (Eastlake) has completed the construction of the Poggi Canyon Interceptor Extension -Reach 2 under an agreement with the City. The agreement allowed pre-funding of that project with funds from the Trunk Sewer Capital Reserve Fund. The City has completed the audit for the project and reimbursed Eastlake for the costs incurred. POGGI CANYON INTERCEPTOR The Poggi Canyon Interceptor is an 18-inch to 21-inch diameter Tunk sewer (except for under 1- 805 which is a 27-inch diameter reach) that conveys all wastewater generated within the Poggi Canyon Basin. Construction of the Interceptor from a connection to the Date-Faivre Trunk Sewer to SR-125 was completed in 2002. The entire length of the Interceptor, except the reach under 1- 805 (Reach 205J, was constructed by private developers and financed through the existing Poggi Canyon Gravity Sewer DIF either through cash reimbursement or credit of future DIF payments. The construction of approximately 660 feet of 27-inch reach of the Interceptor under I-805 (Reach 205) was completed in 2005 by City contract and funded from DIF funds. City of Chi Aprif 2009 61-ti12 Poggi Basin Gravity Sewer Development Impact Fee CHAPTER 3 -BASIN DESCRIPTION With completion of the Salt Creek Sewer in 2005, the city connected the Poggi Canyon Sewer interceptor to the Salt Creek Sewer in Main Street. Eastlake Company completed construction of the Poggi Canyon Interceptor Extension -Reach 2 in 2005. In March of 2008, the City reimbursed Eastlake Company for construction of this improvement pursuant to an agreement between Eastlake Company and the City. POGGI CANYON INTERCEPTOR EXTENSION Portions of Eastlake Greens, including the high school, are within the Poggi Canyon Sewer Basin but initially used a pump station to pump its sewer flows to Telegraph Canyon Basin. Pumped flows were necessary to accommodate the Eastlake Greens development ahead of the construction of the Poggi Canyon Interceptor in Olympic Parkway. Based on approved development plans for Eastlake Parkway and the Eastlake Land Swap subdivision, and selection of a preferred alignment after thorough study, the Poggi Canyon Interceptor was extended from SR 125 to serve the eastern portions of the basin. The final design included deep reaches of sewer in the Land Swap Subdivision and a portion cf Eastlake Parkway that range from 20 to 60 feet deep. These reaches were constructed as dual, concrete-encased sewers with access provided by cast-in-place reinforced concrete vaults. Slide gates were provided in the vaults to control flow between the dual sewers to facilitate maintenance of the deep reaches. This deep sewer enabled the City to prcvide gravity sewer to portions of Eastlake, consistent with Council Policy No. 570-03, a policy that discourages approval of permanent sewer pump stations in lieu of viable gravity alternatives. After substantial negotiation, the final segment, located within the County Water Authority easement was completed in 2008. The City has since decommissioned the pump station and the previously diverted flows are now flowing by gravity to Poggi Canyon Basin. These flows were considered in the 1997 Basin Plan. The Poggi Canyon Interceptor Extension consists of two reaches, Reaches 1 and 2. Reach 1 extends the sewer from the Land Swap commercial parcels, northerly in Eastlake Parkway to the pump station. Reach 1, excluding the decommissioning of the pump station, will be funded utilizing CFD 06-I bond proceeds as previously approved by Council. Reach 1 is not recommended to be a DIF eligible improvement. Reach 2 is serving the southern portion of the Land Swap subdivision and begins at the Poggi Canyon Interceptor just east of SR-125, extending northeastward through the Eastlake Land Swap Commercial parcels to Eastlake Parkway. Pursuant to a Reimbursement Agreement approved by Council in April 2004 (attached as Appendix B), the City reimbursed Eastlake Company for its eligible costs for constructing Reach 2 from Trunk Sewer Capital Reserve Funds. As Reach 2 is serving the same function as the Poggi Canyon Interceptor identified in the 1997 Basin Plan, it is now recommended that Reach 2 be included in the 2009 Update as an eligible DIF facility and be funded with Poggi Canyon Sewer Basin DIF funds instead of Trunk Sewer Capital Reserve Funds. This recommendation is based on: • Poggi Canyon Interceptor Extension -Reach 2 is a trunk sewer and is an extension of the sewer that was included in the 1997 Basin Plan (Reach 221). Construction of Reach 2 has been completed. • Eastlake Land Swap parcels were required to participate in the DIF program. Reach 2 serves these parcels. • Upon build out of the basin, there will be sufficient funds to reimburse the Trunk Sewer Capital Reserve Fund $1,094,707. After setting aside $1.3 million for potential overpayments, reimbursing the Trunk Sewer Capital Reserve Fund $470,556 for interest Poggi Basin Gravity Sewer City of Chula trsfa Development /mpad Fee April 2009 p-713 CHAPTER 3 -BASIN DESCRIPTION earned, and setting aside $120,000 for future administrative costs for the program (see Table 5-4), there is an estimated $441,000 (of the $1,094,707) currently available to reimburse the Trunk Sewer Capital Reserve fund. The requirement to consfruct the future improvements should be placed as a condition to development whereby the developer receives credit for construction of Poggi trunk sewer improvements in-lieu of paying the impact fee. Inclusion of Reach 2 and its costs in the DIF program will not increase the fee. CONNECTION FROM REACH 2 TO SR 125 In addition to Reach 2 as identifed in the Eastlake/City agreement, a short reach of sewer connecting the sewer in Olympic Pkwy at SR 125 to Reach 2 was constructed by Eastlake Company and financed via CFD 061. By now identifying this segment of sewer as a DIF project, the CFD shall be reimbursed the cost of construction for that segment. EASTLAKE PARKWAY PUMP STATION The Eastlake Parkway Pump Station is located adjacent to Eastlake Parkway just north of the San Diego County Water Authority easement. The station was constructed in 1990 to temporarily pump flows generated in the Eastlake Greens subdivision, which is located in the eastern portion of the Poggi Canyon Basin, to the Telegraph Canyon Trunk Sewer. Upon completion of the remaining reach of the Poggi Canyon Trunk Sewer (i.e. the portion under the San Diego County Water Authority Aqueduct), the City decommissioned the pump station, directing flows to the Poggi Canyon Interceptor via the Poggi Canyon Extension. The cost to decommission the Eastlake Parkway pump station will be borne by the City, with funds from Sewer Service Revenues consistent with Council Policy 570-03. Fgure 2 shows the location of the improvements. FUTURE FACILITY IMPROVEMENTS Based on updated land use information and potential diversion of flows, both interim and permanent, several constructed segments of Poggi Canyon Interceptor may need to be replaced with larger diameter pipe or parallel reaches constructed. See discussion in Chapters 4 and 5. 3.3 EDU PROJECTIONS For financial analysis, the land uses for each property are converted to Equivalent Dwelling Units (EDUs), where one EDU represents the estimated sewage generation rate of asingle-family residence. EDUs for various land uses are established by comparing the sewage generation rate for a given land use to that of asingle-family residence. Table 3-1 summarizes the sewage generation rates and EDU equivalency factors for various land uses. The EDU conversion factors are based on a single family dwelling unit sewage generation rate of 265 gallons per day, as established in the City's Subdivision Manual.

The above EDU conversion factors for non-residential land uses are slightly different than shown in the 1997 Basin Plan because that study was based on 2B0 gpd per EDU, not 265 gpd per EDU. LAND USE PROJECTIONS Land use and population projections for ultimate buildout of the basin were estimated from City permits and GIS data, SPA plans, Tentative Maps, and available improvement plans. Existing (permitted) parcel information was obtained from City records and development projections provided by Basin developers where necessary. Table 3-2 shows development projections on an EDU basis. The industrial parcels for Sunbow II, the community purpose facility parcel in Otay Ranch Village 5, portions of Otay Ranch Villages 6 and 12 (Freeway Commercial), Otay Ranch Villages 2 and 7, the Eastern Urban Center (EUC) and Eastlake Land Swap project have remaining EDUs to develop within the basin. Table 3-2 provides a summary, by project, of the remaining EDUs. For additional project detail refer to Appendix G for maps and land use information.

Table 3-2 identifies the proposed tributary EDUs, including the diverted EDUs. Based on the development plans for the Eastern Urban Center, there will be 240 "diverted" EDUs, or a total of 429 EDUs from EUC. The developer of Otay Ranch Village 7 proposes to divert 464 EDUs to Poggi Basin on a temporary basis, until such time as the extension of the Rock Mountain Trunk Sewer (Wolf Canyon basin) is constructed connecting to the Salt Creek Interceptor. ~ The PBS&J Study for EUC, dated January 2008, shows a maximum of 580 EDUs to Poggi Sewer Basin; the preferred alternative limits this to 529 EDUs based on 215 gpd per EDU.

New sewers shall be designed so that the estimated flow depth does not exceed 75% of the pipe diameter (for pipes sizes of 12- inch in diameter or greaten. While this is the criteria for new construction, the .trigger for construction of replacement or parallel sewer pipe is when the depth of flow exceeds 85%. This latter criterion has been used in recent City sewer basin studies as well as to identify projects for the Capital Improvement Program.

City of Chula Wsta April 2009 Poggi Basin Gravity Sewer Development /mpacY Fee -~30 CHAPTER 4 -FUTURE FACILITIES 4.2 FACILITIES FOR FUTURE DEVELOPMENT In 1997, the City had its consultant, Wilson Engineering, prepare the Poggi Canyon Basin Gravity Sewer Basin Plan that identified the trunk sewer improvements that would be needed to accommodate build-out of the Poggi sewer basin. That study provided the basis for the initial impact fee progrdm. The City has since prepared a more comprehensive plan, the Wastewater Master Plan (May 2005). The plan provides a detailed model of the sewage flows in Poggi basin demonstrating adequate capacity of the Poggi basin sewer system based on calibrated flow data (and assuming the improvements identified in the 1997 Basin Plan are constructed)2. Recent technical sewer studies indicate that Reach P270 is the first critical reach to analyze for capacity constraints and that upgrading this reach from an 16-inch diameter pipe to a 21-inch diameter pipe may be needed. The City presently monitors this reach of pipe through its on- going Infrastructure Flow Monitoring Program which involves the installation of portable flow meters at various critical locations citywide ensuring that the City has current and adequate information on the impacts of existing and new development on the City's wastewater collection system. There is a need to re-evaluate the adequacy of other reaches of the Poggi trunk sewer based on current development proposals reflected in the following approved documents: • Overview of Sewer Service for Otay Ranch Village 2, 3 and a portion of 4 (Dexter Wilson Engineering, February 2006); Village 2 Substantial Conformance Tentative Map (Hunsaker and Associates, dated February 12, 2007) reflecting updated land use information; • Eastern Urban Center Technical Sewer Study (PBS&J, January 2008, Update #3); Village 7 Conceptual Sewer Study (PBS&J, April 14, 2004). Table 4.3 identifies the development project and estimated EDUs based on Table 4.2 and on final map and/or approved tentative map information and the above-listed documents. The EDUs were then used to estimate whether the Poggi trunk sewer system could accommodate the ultimate, build-out flows. z Refer to Chula Vista Wastewater Master Plan (May 2005), page 4-34.

Using Manning's equation to determine depth of flows, the flow in two reaches of pipe may exceed 85% of the pipe diameter (or d/D of .85) at build-out of the basin. The following reaches should be monitored to determine the need for replacement and/or for construction of parallel sewer lines. Refer to Pigure 3 for improvement location. • Reaches in Olympic Parkway at Brandywine between nodes P253R3 and P2704; and • Reaches in Olympic Parkway within Sunbow east of Brandywine Avenue between nodes P270 and P305s. Table 4-4 shows the project flows and corresponding capacity measured as the percentage of d/D for the reach of sewer between Nodes P253R and P270. The design capacity of the pipe at 0.5% slope and 85% full pipe flow, is 12,175 EDUs.

The improvements are discussed below. IMPROVEMENT 1 -BETWEEN NODES P253RAND P27O The existing sewer in Olympic Parkway downstream of Brandywine Avenue is an 18" diameter pipe as shown on drawings 97-344 and 00110. Anew 21-inch diameter pipe for this reach at'/. full would accommodate approximately 16,254 EDUs. Comparing to the Maximum Project EDUs of 15,110 shown in Table 4-4, the 21-inch diameter pipe would accommodate the maximum, permanent and committed flows projected within the basin. The cost to increase the size of the sewer pipe in this reach is proposed to be added to the DIF program. The cost estimate assumes replacement of the sewer between nodes P253R and P270. It is recommended that additional sewer modeling and monitoring be undertaken to determine if refinements to the study data would demonstrate adequate capacity for the existing 18-inch pipe. The most critical reach of pipe is between nodes P265 and P270. IMPROVEMENT 2 -BETWEEN NODES 270 AND 305 The existing sewer in Olympic Parkway upstream of Brandywine Avenue is an 18" diameter pipe as showr~ on drawings 99-386 through 99-373. Anew 21-inch diameter pipe for a portion of this reach at'/, full would accommodate 16,254 EDUs. Comparing to the Maximum Project EDUs of 13,869 shown in Tables 4-5, the 21-inch diameter pipe would accommodate the maximum, permanent and committed flows projected within the basin. The cost estimate assumes replacement of the sewer between nodes P270 and P305. It is recommended that additional sewer modeling and monitoring be undertaken to determine if refinements to the study data would demonstrate adequate capacity for the existing 18-inch pipe. The most critical reaches of pipe are between nodes P270 and P275 (0.5% slope)and between nodes P295 and P305 (0.6% slope).

These projects include construction of approximately 29,200 feet of sewer main (Reaches 201 through 221) that constitute the Poggi Canyon Interceptor. The 2009 Update to the DIF program adds Poggi Canyon Interceptor Extension -Reach 2 (the reach of sewer across the Eastlake land swap commercial parcels) to the program and identifies additional improvements needed to serve forecast development in Poggi basin. The entire Interceptor as identifed in the 1997 Basin Plan and extension, except Reach 205 and a portion of Extension -Reach 1, has been constructed by developers. (Figure 2 identifies the reaches.) Chapter 4 discusses additional improvements that may be needed to serve build-out of the basin if the City allows the Eastern Urban Center and Village 7 to divert project flows to Poggi. Table 5-1 identifies the estimated cost for the additional improvements and Table 5-2 provides construction costs for all projects. 5.1.2 PROJECT COSTS AND OUTSTANDING CREDITS All known necessary improvements identified as regional sewer facilities in the 1997 Basin Plan within the Poggi Canyon Basin have been completed, including Reach 205. Non-regional sewer improvements recently constructed within the Poggi Canyon Sewer Basin include a remaining portion of the Poggi Canyon Interceptor Extension -Reach 1, within the San Diego County Water Authority Right of Way, and the decommissioning of the Eastlake Parkway Pump Station. The construction of the remaining portion of the Poggi Canyon Interceptor Extension -Reach 1 is eligible to be financed utilizing CFD 06-I bond proceeds (not DIF eligible) and the decommissioning of the Eastlake Parkway Pump Station will be funded utilizing Sewer Service Revenue Funds in accordance with City of Chula Vista Policy No. 570-03. Based on the provisions of Sections 15 and 16, of Ordinance No. 2716, a developer who agrees, or is required as a condition of approval of a development permit, to construct a segment of the facilities would be entitled to receive a reimbursement or credit at the City's option. Poggi Canyon Interceptor Reach 201-207 Reaches 201 through 204 and 206 through 207 were constructed by Ayres Land Company in 2001 and the developer was fully reimbursed for these costs. The final construction cost amounted to $1,046,032. Poggi Canyon Interceptor Reach 208-213 Ayres Land Company constructed reaches 208 to 213, which are eligible for DIF credits. Based on the information provided by the developer, it was determined that the credit for Ayres Land Company for constructing Reaches 208 to 213 amounted to $136,205. All of this credit has been applied to Sunbow II building permits. (Note that the City upsized a portion of this reach of sewer in connection with CIP STM 344, Drawing 00-110, but apparently was not funded from Poggi Sewer DIF funds.) City of Chula ~sfa April 2009 Poggi Basin Gravity Sewer Development Impact fee 65-~38 CHAPTER 5 -DIF ANALYSIS Poggi Canyon Interceptor Reach 205 The City constructed reach 205 in 2005 and the final construction cost for the project amounted to $1,041,283. In addition, $393,635 was expended for staff time for a total project cost of $1,434,918. The Poggi Canyon Sewer Basin DIF funded Reach 205. Poggi Canyon Interceptor Reach 214-217 Reaches 214 to 217 were constructed by the Otay Ranch Company and costs reimbursed from CFD 99-1 funds. Based on the construction cost audit, the cost for these reaches is $638,748. Poggi Canyon Interceptor Reach 218-219 Reaches 218 to 219 were constructed by the McMillin Companies and costs reimbursed from CFD 97-3 funds. Based on the construction cost audit, the cost for these reaches is $412,938. Poggi Canyon Interceptor Reach 219-221 Reaches 219 to 221 were constructed by the Otay Ranch Company and costs reimbursed from CFD 99-1 funds. Based on the construction cost audit, the cost for these reaches Is $283,190. Poggi Canyon Interceptor Extension The Extension -Reach 2 (across the Eastlake Land Swap commercial parcels) was constructed by Eastlake Company. Based on the construction cost audit, the cost for this reach is $1,094,707. Reimbursement to Eastlake Company from the Trunk Sewer Capital Reserve Fund was made in March 2008 pursuant to an agreement between Eastlake Company and the City. It is recommended that the DIF reimburse the Trunk Sewer Capital Reserve Fund for pre-funding of the improvements. In addition, a short segment of sewer in Olympic Parkway from SR 125 to the Interceptor Extension -Reach 2 was constructed by Eastlake Company and financed via CFD 061. Based on the bid for this segment, the cost of this reach is $24,000. Reimbursement of these costs has been paid from the CFD to Eastlake Company. With the inclusion of this reach as a DIF eligible improvement, the City shall reimburse the CFD from the DIF funds for this cost. Capacity Enhancement Improvements Based on currently approved land uses, the 18-inch diameter sewer pipe in Olympic Parkway east and west of Brandywine Avenue, will exceed the pipe capacity of 85% full pipe flow. The costs to upsize the reaches to 21-inch diameter sewer pipes are included in the update to the DIF program. Table 5-1 summarizes the future cost of improvements and Table 5.2 summarizes the overall costs of the program.

City of Chula Ysfa Poggi Basin Gravity Sewer Apri12009 Development Impact Fee 6~-340 CHAPTER S - D1F ANALYSIS 5.1.3 OTHER DIF OBLIGATIONS As identified in the 1997 Basin Plan, the City was to contribute to the cost of construction for Reaches 201 through 204 and Reaches 20o through 207 because these reaches, located west of Oleander Avenue, would serve existing development as well as future development within the basin and required upsizing at the time the DIF was established. Trunk Sewer Capital Reserve Funds, from revenue generated from development connection charges, were used to pay for these reaches. 8y Resolution No. 18823, Council appropriated and transferred $1,756,440 to the Poggi Canyon Sewer Fund to finance this portion of the Poggi Canyon trunk sewer. The final construction cost for Reaches 201 through 204 and Reaches 206 through 207, paid to Ayers Land Company, amounted to $1,042,520.76 (not including $3,511 assumed reimbursed to City for its related costs). The balance of $710,408 was transferred back to the Trunk Sewer Capital Reserve Fund. However, interest earnings from the $1,756,440 still remain in the DIF fund. Based on information provided by the City's Finance Department, through June 30, 2008, $470,556 shall be transferred from the DIF program to the Trunk Sewer Capital Reserve Fund. This transfer is reflected in the updated fee rate. The documentation for payments to Ayres is included in Appendix E. In several Otay Ranch neighborhoods, both Otay Ranch Company and McMillin Company constructed the improvements as well as the builder/developer paying the fee. As such, refunds estimated in the amount of $1,329,771 should be made to account for this overpayment of fees. Table 5-4 reflects the amounts. Appendix D contains a summary of the building permit data regarding payments. Costs associated with preparation and administration of the DIF, are included in the Poggi Basin DIF. 5.1.4 AVAILABLE REVENUES Through June 30, 2008 the City has collected $2,988,700 in DIF fees for the construction of the required facilities. In addition, the fund has earned an additional $937,171 in interest both on the fees collected and the transfers made to the Fund from the Trunk Sewer Capital Reserve Fund. Table 5-3 shows the amount collected since the inception of the Poggi Canyon Sewer Basin DIF.

This is mainly due to the following reasons: • Construction cost savings due to the sewer being constructed concurrently with the roadway improvements; • Interest earnings on the fund balance; and • Increase in the number of participating EDUs based on updated development strategies. These reductions are partially offset by the addition of improvements to the, program to accommodate the additional EDUs due to intensification of land uses and potential diversion of flows.

The City should monitor the critical sewer reaches to determine when the improvements will be needed. 4) Monitor other critical reaches of sewer, those where depth of flows are estimated to be between 75% and 85% of the pipe diameter, as identified in Table 4-6. 5) Based on updated information, reduce the fee to $265/EDU reflecting a) the updated cost information, b) additional improvements, c) available revenue after reimbursements are made, and d) updated EDU projections. Note that there is a change per EDU for the non-residential rates. 6) Transfer interest related to the $1.7 million Trunk Sewer Capital Reserve Fund back to the Fund. The amount of interest will depend on the date the transfer is made. Based on City finance records the interest accrued through June 30, 2008 is $470,556. 7) When the City determines suffcient funds are available, transfer funds from the Poggi Canyon DIF to reimburse the Trunk Sewer Capital Reserve Fund for consfruction of improvements associated with Poggi Canyon Sewer Interceptor Extension -Reach 2 in the amount of $1,094,707. 8) When the City determines sufficient funds are available, appropriate $1,329,771 in Poggi Canyon Trunk Sewer DIF funds to refund the appropriate developments/CFDs of OTay Ranch Village 1 West, Otay Ranch Villages 1 and 5, McMillin's Otay Ranch Villages 1 and 5, and CFD 061 for overpayment of fees as outlined in Chapter 5 and the Appendix. The provisions for such refund shall be determined by the City Attorney.. 6.2 ENVIRONMENTAL REVIEW The future facilities identified in this report are intended to provide increased sewer capacity to mitigate the impacts of future development. No facilities will actually be constructed until all necessary environmental reviews have been conducted. Further studies, including environmental review, may show superior alternative projects that also satisfy the increased capacity need. 6.3 ANNUAL ADJUSTMENT FACTOR It is recommended that the fee be adopted with provisions for an annual adjustment factor. The recommended index is the Engineering News Record - Consruction Cost Index for the Los Angeles area. To be consistent with other City fee increases, it is recommended that the July to July index be used, to be effective in October of each year beginning in the year 2009.

DISCUSSION: At the request of the City, the Eastlake Company analyzed several alternatives to determine the best method for providing a gravity sewer line for the southerly portion of the Eastlake Greens project (currently being pumped up to the Telegraph Canyon Sewer Trunk). Based on limitations imposed by existing improvements and topography, the best alternative required construction of the Poggi Canyon Trunk Sewer Extension, a deep gravity sewer line ranging in depth from 20' to 60'. The sewer line follows Eastlake Parkway south (Reach 1), and then crosses the commercial land swap parcel (Reach 2) where it connects to the Poggi Canyon Trunk Sewer at Olympic Pazkway (see Attachment 1). -After thorough consideration of the alternatives, Eastlake Company proceeded with and completed construction of the Poggi Canyon Trunk Sewer Extension. Reimbursement Agreement Reach 2, costing approximately $1.2 million, shall be considered first. This reach extends from Eastlake Parkway, approximately 1600 feet westerly to the existing sewer located in Olympic Parkway. The City was interested in having this trunk line constructed because it is a required 6 9 ~ Page 2, Item Meeting Date 4/27!04 regional facility and its construction would allow the Eastlake Parkway Pump Station to be decommissioned. The decommissioning is necessary for the following reasons: 1. Lack of safety features: The Eastlake Pazkway Pump Station was originally constructed as a temporary pump station in conjunction with the Eastlake Greens 'development, without provisions for various safety features that are now typically incorporated into permanent pump stations (e.g., an external storage basin providing at least 6 hours storage for spill control, dual farce mains for re-routing flows, and other necessary redundant features). The station would have needed a prohibitively expensive retrofitting to convert it to a permanent pump station. 2. Siting criteria: The Eastlake Pazkway Pump Station is unsuitably located adjacent to an Elementary school and other residential facilities. 3. Lone term cost of maintenance: The City has been obligated to maintain the pump station at a cost to the Sewer Service Revenue Fund of approximately $25,000/yeaz. With the wastewater now being conveyed by means of gravity down to the Poggi Canyon sewer trunk line, there is no further need to pump wastewater up to the Telegraph Canyon sewer trunk line. For constructing Reach 2 of the Poggi Canyon Trunk Sewer Extension, staff recommends that the Eastlake Company be reimbursed for their costs subject to conditions set forth in a Reimbursement Agreement (Exhibit A}. Moreover, since the construction of this major trunk line is consistent with the purpose for establishing the Trunk Sewer Capital Reserve Fund, staff recommends that those funds be used to reimburse the Eastlake Company. Revenue collected in this fund is used to build new trunk sewer systems and to enlazge the capacity of the wastewater collection and treatment system (see Attachment 2). It is appropriate to fund the proposed reimbursement from the Trunk Sewer Capital Reserve Fund since the City had a vested interest in constructing this segment of the Poggi Canyon Trunk Sewer Extension. The Reimbursement Agreement will enable the City to reimburse the Eastlake Company for costs not to exceed $1,200,000 subject to certain conditions. This amount does not include an additional estimated $10,000 in future City staff costs to ensure compliance with the reimbursement agreement, and $20,000 in City staff time already incurred for design activities related to this project. The reimbursement will be made no sooner than July 1, 2004 to ensure that sufficient Trunk Sewer Capital Reserve funds are available. Second Amendment to the Acquisition/Financing Agreement The Eastlake Company has requested that the City consider amending the Acquisition/Financing Agreement for CFD 06-I to incorporate procedural changes regarding the payment process, to identify Poggi Canyon Trunk Sewer Extension Reach 1 Improvements as distinct and separate from Eastlake Parkway roadway Improvements, to make each traffic signal Improvement a distinct and separate one, and to update cost estimates to reflect current information (Attachments 3 and 4). The procedural changes are consistent with other recent AcquisitiotilFinancing Agreements approved by Council. 6-7~ Page 3, Item r Meeting Date 4127!04 The construction costs for Reach 1, which aze eligible for CFD 06-I financing, aze substantially higher than estimated in the original Acquisition/Financing Agreement. The revised estimate is approximately $1.2 million. Bond counsel therefore recommends that Council approve a Second Amendment to the Acquisition(Financing Agreement to reflect the higher costs. Approval of the second resolution approves the form of the Second Amendment to the Acquisition/Financing Agreement. Sotne of the changes relate to the Poggi Canyon Sewer Trunk Extension and some do not. The amendment will accomplish the following: Allow the Developer to request the Base Increment payment for any authorized improvement without setting the final Purchase Price. The Base Increment will equal 75% of the eligible audited costs to construct the improvement. Prior to requesting the Base Increment, the improvement and a1I its components must still be substantially completed. . 2. Defer determination of the final Purchase Price of the Improvement to the time at which the final payment is approved. Increase the cost estimate for the Poggi Canyon Trunk Sewer Extension Reach 1 and idenfify it as a sepazate Improvement from the Eastlake Pazkway roadway Improvement, and allow for a sepazate reimbursement. 4. Identify each traffic signal as a separate and distinct Improvement as illustrated in the revised Exhibit A of the amended Acquisition/Financing Agreement. Additional traffic signals have been included in the updated list. 5. Update the Cost Estimates for those Improvements identified in Exhibit A. FISCAL IMPACT: There is no impact to the General Fund. Council approval of the resolution approving the Reimbursement Agreement with the Eastlake Company appropriates $1,230,000 from the Trunk Sewer Capital Reserve Fund to a new CIP for Reach 2 of the Poggi Canyon Trunk Sewer Extension. The revised costs of approximately 51,200,000 for Reach 1 will be funded from CFD 06-I bond proceeds. Al] costs related to creating the second amendment to the Acquisition/Financing Agreement for CFD 06-I will be borne by the developer. Attachments: 1. Plat of sewer reaches 1 and 2 2.

(Ord. 2466 § 2, 1991}. 3-4 6-~- s ATTACHMENT 3 SUI~IMARY OF CHANGES TO ACQUISITION AGREEMENT' Staff has begun implementing the Acquisition Agreement and recommends, together with the Developer and bond counsel, the following changes to the Acquisition Agreement: 1: Purchase Price Staff recommends a change in the timing of the determination of the Purchase Price of an Improvement consistent with the latest Acquisition Agreement approved by Council for another developer. The current Acquisition Agreement provides that reimbursement for eligible costs of an Improvement may be made in two increments, the Base Increment (75% of the Purchase Price) and the Retained Increment (25% of the Purchase Price). The Purchase Price, the amount the developer may be ultimafely reimbursed, is set at the time the Base Increment payment is made for an Improvement. This is problematic because at the time the developer is eligible to receive the Base Increment (the Improvement is deemed substantially complete by the City) not all minor costs may be known and audited. Under the current Acquisition Agreement, the developer would have two options for addressing this: (1) delay the request for the Base Increment by several months until all fmal costs aze known and losing several months interest on that reimbursement or (2) do not include all eligible costs in the CFD. In lieu of these options, Eastlake Company has requested that the Purchase Price be set instead at the time the Retained Increment reimbursement is made when every final invoice has been paid, punch list items addressed, and "as-builts" processed among other items. This change would enable Eastlake Company to request reimbursement in two increments as follows: (1) the Base Increment which would be limited to 75% of the eligible, audited costs of the Improvement not to exceed 75% of the estimated cost outlined in the AF Agreement, and (2) the Retained Increment which would include the 25% of the eligible, audited cost retained with the Base Increment payment, together with any additional eligible, audited costs submitted for reimbursement. The Base and Retained Increments combined would represent the Purchase Price. Substantial completion of the Improvement would still be required prior to making the Base Increment reimbursement as well as feral completion and acceptance by the City of the Improvement prior to making the Retained Increment payment. According to Eastlake Company, this payment schedule will better support its cash flow management for constructing the CFD roadway improvements such as Olympic Pazkway, Eastlake Pazkway, and Otay Lakes Road in accordance with the aggressive timeline for completing these key transportation facilities benefiting the community. This is consistent with the latest Acquisition Agreement approved for other developments. 6-~ `'° 2. Sewer Improvement and Cost -Eastlake Pazkway The cost estimate for Eastlake Parkway under the current Acquisition Agreement does not include the entire cost of the deep sewer line constructed by Eastlake Company because the sewer alignment was not determined at the time the Acquisition Agreement was executed. Due to the significant cost of this facility (estimated at $1.2 million for the reach proposed for acquisition), Best Best and Krieger, bond counsel for the CFD, recommends amending the AF Agreement to reflect the additional costs of this improvement. The sewer line that will be included for acquisition in CFD 06I follows the Eastlake Pazkway alignment for approximately 1500 feet (Reach 1 on Attachment I). In addition, staff recommends the sewer component of the Eastlake Pazkway Improvement be identified as a separate Improvement. The current Acquisition Agreement provides that for a Base Increment reimbursement for a roadway Improvement to be made, all of the roadway components such as (i) grading, including site preparation and mobilization, (ii) wet and dry utilities within the right-of--way, (iii} storm drain facilities, (iv) paving, (v) curb, gutter, sidewalk, medians, (vi) traffc signals, (vii) lighting, and (viii) all other appurtenant improvements must be substantially complete. By making the sewer a separate Improvement, reimbursement for this major sewer line will not be delayed until substantial completion of the roadway Improvement. Or if there aze any issues related to the sewer outside of the Eastlake Parkway right-of--way, the Eastlake Pazkway reimbursement will not be delayed. 3. Traffic Sienals As defined in the Acquisition Agreement for CFD 06I, the Traffic Signal Improvement includes all traffic signals. For a Base Increment reimbursement for traffic signals to be made, every traffic signal would need to be substantially completed. Eastlake Company has requested that each traffic signal be listed as a separate Improvement to enable reimbursement as each traffic signal is completed. The Acquisition Agreement also adds additional traffic signals to the eligible list of improvements. 4. Costs Eastlake Company has requested that the cost estimates in Exhibit A of the amended Acquisition Agreement be revised due to more recent and accurate cost analysis and to identify the estimated costs for each Improvement as amended by the Second Amendment.

The detailed discussions within each chapter and the appendices provide the basis for the final development impact fee recommendation presented in Chapter 5. Several large developments anticipated or underway within4he Poggi Canyon Sewer Basin will generate a significant amount of wastewater. The current sewers are not large or extensive enough to serve these new developments. The purpose of this report is to recommend the facilities needed to serve these new developments and to determine the amount of fees payable by these developments which are needed to finance the expanded facilities. The tasks to be addressed in the report are summarized. The report will determine ultimate development levels and create a computer model to determine the sewer sizes needed for the buildout of the Poggi Canyon Basin_ The construction costs for the proposed sewer improvements will be discussed. The study area is defined geographically and the different property ownerships are identified. From this information, a summary of estimated Equivalent Dwelling Units {EDUS) for the buildout of the basin is given. The sewage generation factors and the design criteria used in the report are presented. The wastewater loadings determine, to a large degree, the necessary facilities for the collection, treatment, and disposal of wastewater. Existing sewage flows within the Poggi 6-114 The alignment of a future Poggi Canyon Basin sewer system is discussed. The existing gravity sewer facilities are descri'oed and a summary of alternatives is given. The three alternatives given are the replacement in place of the existing sewer; the construction of a parallel alignment of ultimate sized gravity sewer within existing streets; and the construction of the ultimate sized gravity sewer within a storm drain easement: A .summary of the results from the computer models run is shown. The preparation of the model is discussed and guidelines for the model are given. The results of the computer model are given and analyzed. The 3E-inch Reach 9 Regional Interceptor gradsty sewer was found to be adequate for ultimate Poggi Canyon Basin flows. The 18-inch sewer reach under Interstate 805 was found to be under-capacity for ultimate Poggi Canyon Basin flows. Recommended improvements to the Iine aze discussed and a cost summary for the costs is given. Then a possible phasing of improvements in Poggi Canyon Basin is given. Chanter 5 - Financins The development impact fee distributes the cost of the required system upgrades in as equitable manner. The City of Chula Vista will fund the upgrade of a portion of the existing system. Using the summary of EDUs in Chapter 3, the total cost of recommended improvements less what will be funded by the City of Chula Vista is divided among all future EDUS. For the Poggi Canyon Basin, the resulting development impact fee is 3400 per EDU. The development impact fees are also shown according to land use. 2 6-115 CHAPTER 2 BACKGROIIND On September 9, 1996, the City of Chula Vista executed a purchase order contract with Wilson Engineering to prepare the Poggi Canyon Sewer Basin Study. This report is to provide an evaluation of ultimate sewage flows within the Poggi Canyon Basin and the gravity sewer facilities needed to convey these flows. The intention of this report is to assimilate the engineering design data as well as incorporate future planning information along with the estimated construction and administrative costs associated with the proposed infrastructure requirements.. With this data, the City of Chula Vista will be able to estabiish a Development Impact Fee to fund the required improvements within the Poggi Canyon Basin. A summary of the tasks which will be accomplished within this report are as follows: 1, Determine buildout development levels within the Poggi Canyon Basin, based on planning information and tentative maps. 2. Create a computer model of the Poggi Canyon Basin Sewer Interceptor in order to determine the size of the gravity sewer required to accommodate ultimate buildout conditions. 3. Recommend the size and location of sewer improvements. 4, Provide a map showing the location of the sewer improvements as well as all the contributing properties within the Poggi Canyon Basin. 3 6-116 5. Estimate engineering, administrative and cnastruction costs for the recommended ustprovements within the Poggi Canyon Basin. 6. Establish a sewer Development Impact Fee based on the costs of the Poggi Canyon Basin improvements and the number of future dwelling units within the basin that will require these facilities. The Poggi Canyon Basin Sewer improvements, which are studied in this report, extend from the upper limits of the Poggi Canyon Sewer Drainage Basin west to the future location of a Regional Trunk Sewer idemified as Reach 9 of the Salt Creek Basin Interceptor System. The Reach 9 portion of the Salt Creek Basin Interceptor System was developed as part of the Salt Creek Basin Gravity Sewer Analysis prepared in November 1994 for the City of Chula Vista. This report will provide the recammended size of the Reach 9 Interceptor in order that ultimate capacity from the Poggi Canyon Basin will be accommodated. However, the costs associated with Reach 9 azea not part of the DIF being established for the Poggi Canyon Basin. The City has indicated that Reach 9 will be aCity-funded facility because it provides regional service to the City of Chula Vista. Therefore, the Poggi Canyon Basin Sewer System recommendations will terminate at the approximate future location of the Reach 9 Regional Sewer Interceptor. The Pnrnoae and Need for a Sewer Basin Plan The City of Chula Vista has recognized that development within the Poggi Canyon Basin east of Interstate 805 is beginning to gain momentum. Because of the imminent development within the Poggi Canyon Basin, the City would like to establish the ultimate buildout infrastructure requirements as well idetttify costs for those future facilities. This will provide the basis for the City to establish a sewer benefit area fee through which the required ultimate sewer improvements can be financed. The purpose of the sewer basin plan is to collect, in one comprehensive document, the most current land planning information within the Poggi Canyon Sewer Drainage Basin and determine the sizes of facilities required for ultimate development. A calculation of the ultimate expected equivalent dwelling units within the basin will allow a sewer basin fee to 4 6-117 be established based upon the remaining number of equivalent dwelling units to be developed in the Poggi Canyon Basin. The remaining number of equivalent dwelling units is based upon a research of the properties within the basin and the development potential as of April 1997. Future development potettial is determined by existing approved tentative maps, submitted and approved SPA plans, and City of Chula vsia General Plan Land Uses where ao other information is available. Because of the inherent changes in future development plans, it is important to recognize the need for periodic updates to the information presented in this report_ Updates should be performed at regular intervals of five years duration as a minimum. ]n the case where substantial development is occurring at one time, and significant portions of the ultimate sewer infrastructure are being constructed, updates should be performed to ensure that the facilities being constructed will satisfy the ultimate basin requirements. The Poggi Canyon Basin Sewer Study Area extends from west of Interstate 805 to the EastLake Development in the eastern sector of the City of Chula Vista. A portion of the study azea is already developed. This is the portion that straddles Interstate 805 and extends from south of Palomar Street to Otay Valley Road. The future extension of the Poggi Canyon Sewer is expected to follow East Orange Avenue, east of Interstate 805. The eastern boundary of the Poggi Canyon Study Area extends just ]seyond the future intersection of East Orange Avenue and State Route 125. The Poggi Canyon Sewer Basin is located adjacent to and south of the Telegraph Canyon Basin and is bounded on the south by the Wotf Canyon Basin and the Salt Creek Basin. Except for the existing development on either side of Interstate 805 and some development within the EastLake project east of the future State Route 225, the majority of the Poggi Canyon Basin is currently undeveloped. Exhibit "A°, attached to this report, identifies the boundary of the Poggi Canyon Basin on 800 scale topography, along with the location of manholes, reach identification numbers, and flows used for the computer model. 5 6-118 Several different property ownerships have been identified within the Poggi Canyon Basin Study Area. The following is a list of these ownerships: 1. Existing development on either side of Interstate 805. 2. Sunbow II 3. Charles H. Gerhardt 4. Allen L. Gerhardt, Jr. 5. Otay Ranch 6. Otay Ranch Village 1 7. Otay Ranch Village 5 8'. McMillin 9. Eastlake Development 10. County Landfill 1 I . Otay Water District The larger of the properties within the Poggi Canyon Sewer Basta include Sunbow II, Otay Ranch, Otay Ranch Villages 1 and 5, and Eastlake. Two of the ownerships within the Poggi Canyon Basin (County Landfill and Otay Water District properties) have been identified as corrtributing no future. sewer flows into the Poggi Canyon Basin Sewer Interceptor. If future activities within these two ownerships result in the generation of sewer flows, the plan will require revision. Table 2-1 on the following pages provides a summary of the detailed laced planning and sewage generation information for all undeveloped properties within the Poggi Canyon Basin Study Area. This table excludes information about existing development within the Poggi Canyon Basin en either side of Interstate 805. Data on existing developmeat and existing sewage flows will be provided in greater detail in Chapter 3 of this report. The data included in Table 2-I was compiled using the most current available land planning 6 6-119 information for the various ownerships. Data for the Sunbow II project was obtained from the Sunbow II Tentative Map and Proposed Site Utilization Plan. Information for the Otay Ranch was obtained from the Dray Ranch General Development Plan document. Information for the McMillin property was obtained from the Otay Ranch SPA 1 submittal document. For Otay Reach Pillages 1 and 5, the Tentative Map {C.V.T. 96-04) was used. The data for development within the Eastlake project was obtained from two different sources. First, the development within the Eastlake Greens was obtained from a spreadsheet compiled by Eastlake Development. The information for the Iand swap area of Eastlake was obtained from the City of Chula Vista and land uses were based on the City's General Plan. The land use data for the remaining small properties scattered throughout the basin is also based on the City of Chula Vista General Plan. Appendix A includes additional information relative to the source of the land use data for many of the properties within the Poggi Canyon Basin. Appendix A is consistent with Table 2-I in that sewage generation is based on 280 gpd/EDU. Appendix B duplicates the information presented in Appendix A except that Appendix B calculates sewage generation based on 265 gpd/EDU. 7 6-120 TABLE 2-1 PROPERTIES AND EDUa WITHIN THE POGGI CANYON BASIN STUDY AREA rn N Sunbow II TABLE 2-1 (Continued) PROPERTIES AND EDUa WITHIN TIIE POGGI CANYON DASIN 57'UDY AREA CI-arlea II.

S X Q,,.g tc'~, for Q is gpm. The value of Meaning's "n" used for the analysis ofthe Poggi Canyon Basin Sewer System is O.OI3. This value is commonly used for design of new sewer systems. It is not specific to any pipe material as it is not known what gipe material may be used in any reaches of the Poggi Canyon Basin Sewer System. Values of "n" in reference materials vary from 0.011 to 0.015 for lined cast iron pipe and vitrified clay pipe. For plastic pipe, values typically range between 0.011 and 0.015. The peaking factor used within the computer model is based on an equation that was input into the computer model. This equation approximates the peaking factor curve in the City of Chula Vista Subdivision Manual. Several points along the curve were checked to verify that the peaking factor used in the computer model is equal to or greater than that shown in 18 6-131 the peaking factor curve within the subdivision manual. These calculations are provided in Appendix F. The sewage generation factors to be used for this type of planning study are critical for the appropriate sizing of ultimate sewer facilities. Table 2-3 provides a summary of the sewage geaeration factors used within this report for different land uses within the Poggi Canyon Basin Study Area. Two sets of factors are presented in Table 2-3 and these factors vary only is the average daily flow generation for residential land use. The higher generation factors, including 280 gpd per unit for single family and 210 gpd per unit far multi-family residential, are caasistent with the City of Chula vista Subdivision Manual for new developmem. All computer analyses relating to sizing of parallel, replacement or new sewer mains will be based on the higher set of sewage generation factors. The lower set of factors for the residential land uses will be used when analyzing flows through existing gravity sewer facilities within the Poggi Canyon Basin.

This area is on either side of Interstate 805 along Oleander Avenue and Melrose Avenue. It extends south to Otay Valley Road. In order to assist in establishing the existing flows within the Poggi Canyon Basin, flow monitoring was done by the Ciiy of Chula Vista on the existing 8-inch gravity sewer east of Interstate 805 in Oleander Avenue. The results of the flow metering are included in Appendix C. This flow metering data was correlated with the existing number of dwelling units within the basin upstream of the flow metered location. The result was a calculated sewage flow per EDU quantity which was used for comparison of the calculated flow generated from the existing development within the Poggi Canyon Basin which is currently sewering down Oleander Avenue and Melrose Avenue. Existing EDUs within this area were determined by counting lots from the sewer base maps obtained from the City of Chula Vista as well as performing field investigations of commercial and multi-family areas to better establish the actual cumber of dwelling units or other types of land uses within the basin. Table 3-1 presents a summary of the existing land uses and dwelling units within the developed portion of the Poggi Canyon Basin. (Note that the developed portions of the Poggi Canyon Basin exclude any portion of Eastlake which has been developed. All existing Eastlake development within the Poggi Canyon Basin is currently being pumped to the Telegraph Canyon Basin Sewer System.) 21 6-134 TABLE 3-1 Summary of Laad Uses within Ezisting Developed Portion of Poggi Canyon Basin Area East of Interstate 805 Single Family 658 du 658.0 Multi-Family 28b du 214.5 Commercial 0 0 Elementary School 2 64.3 Area Rest of Interstate 805 Single Family 496 du 496.0 Multi-Family 343 du 257.3 Commercial 8.1 ac 72.3 Elementary School 1 32.1 Appendix D includes a calculation which correlates the flow per EDU for the existing development within the Poggi Canyon Basin to the metered data. The calculation shows that the existing flow per EDU is approximately 274 gpd per EDU. For the Poggi Canyon Basin Sewer System analyses, the existing units in the basin will be multiplied by 280 gpd/EDU for analysis of new piping, or 265 gpolEDU for analysis of existing pipe. The determination of the member of EDUs within the basin will be made using the appropriate sewage generation factors column from Table 2-3. 22 6-135 The land planning informaiion provided by the City of Chula Vista as well as information provided directly from developers such as Eastlake is the basis for the development of ultimaie sewage flows generated within the Poggi Canyon Basin. Table 3-2 presents the ultimate sewage flow estimated for each of the properties within the Poggi Canyon Basin_ This table also includes the equivalent dwelling units for the ultimate flow from each of the properties.

The existing development within the Poggi Canyon Basin straddling Interstate 805 is judged to be built out. There may be a few empty lots scattered throughout 23 6-136 that portion of existing development but nothing significant in terms of additional flow generation to the Poggi Canyon Sewer. Existing flows within the basin are summarized in Table 3-1. As mentioned earlier in this report, Eastlake has some existing development within the boundary of the Poggi Canyon Basin. Because there is no existing gravity sewer outlet for this area of Eastlake, a sewage lift station has been constructed along Eastlake Parkway to pump all sewage flows generated within the Poggi Canyon Basin north to the Telegraph Canyon Basin. Table 3-3 shows the breakdown between total buildout units and the amount of development already built. Table 3-3 also identifies the current level of development within the Eastlake project, which is being pumped to the Telegraph Canyon Basin. Presently this amounts to 222,260 gpd (163.2 gpm), which is pumped to the Telegraph Canyon Basin. When the Poggi Canyon Basin Sewer Interceptor is constructed east to the Eastlake boundary, the Eastlake Parkway Pump Station will be abandoned in favor of gravity sewering the portion of the Eastlake Development within the Poggi Canyon Basin. 24 6-137 Eastlakt Parkway Pmm~ Station Abandonment. The Poggi Canyon Basin Study is based on the assumption that the Eastlake development will ultimately connect to the Poggi Canyon Basin Sewer System. The basis for the Poggi Canyon Basin Sewer improvement fee calculated in this study includes the units within the Eastlake development which are within the Poggi Canyon Basin. l:a order for this study's assumption to remain valid, the Eastlake Pazkway Pump Station must be abandoned and flows must be re-routed to the future Poggi Canyon Basin sewer. The Eastlake Parkway Pump Station is situated within the Poggi Canyon Basin on the west side of Eastlake Pazkway. It currently provides sewer service to a portion of the Eastlake development which gravity flows toward Poggi Basin. Since ao facilities exist within Poggi Canyon Basin that faz east, the pump station diverts the sewage flow to the Telegraph Canyon Basin. When the Poggi Canyon Basin Sewer System is constructed in East Orange Avenue to the eastern edge of Otay Ranch Village S, there will be an opportunity to abandon the Eastlake Parkway Pump Station in favor of gravity sewering the pump station's service area to the Poggi Canyon Basin sewer. In order for this io be accomplished, a gravity sewer extension will have to be constructed from the pump station south and west under the future State Route 12S right-of--way. In addition to the SR 125 obstacle, there are also two easements which will have to be crossed: SDG&E, and San Diego County Water Authority (SDCWA). Since the planning and design of the State Route 12S project is currently in progress, it would be timely for the City of Chula Vista to prepare an alignment study for the proposed sewer extension. otay Ranch Village 5 is also beginning seal design. Therefore the tie-in point can be coordinated based on the constraints imposed by the design of SR 125. This section of the report will describe the existing gravity sewer facilities within the Poggi Canyon Basin and discuss alternative alignments for the ultimate Poggi Canyon Basin Sewer Interceptor. 25 6-138 Fzisting ~ravi Sewer Facilities. Currently, the Poggi Canyon Basin Sewer extends from the DatE-Faivre line at the intersection of Palm Avenue and Rancho Drive north and east to Orange Avenue east of Interstate 805. The existing pipeline ends a few hundred feet short of the intersection of Brandywine Avenge and Orange Avenue. The pipeline through this reach is primarily 8-inch with a few sections of 12-inch, 18-inch and 21-inch pipe. The portion of gravity sewer south of Dray Valley Road in Melrose Avenue and Rancho Drive up to the Date-Faivre line is 12-inch diameter. From Otay Valley Road north in Melrose Avenue, the pipeline is 8-inch diameter. Underneath the Interstate 805 freeway, there is an existing 18=mch diameter pipeline. In Oleander Avenue on the east side of Interstate 805, the pipeline is again 8-inch diameter up to approximately Satinwood Way. At this point, it increases to 21-inch diameter through a condonrinium complex until it reaches Orange Avenue where there is an existing section of 18-inch pipe. Disccssion of Alternative Alignments. The proposed alignment for the Poggi Canyon Basin Sewer Interceptor cast of the existing 18-inch sewer line in Orange Avenue is proposed to be within the alignment of East Orange Avenue. East Orange Avenue is slated to extend through Sunbow II, east through Otay Ranch, then through the Otay Ranch Villages I and 5 area and finally past Eastlake. Preliminary road alignment studies show this roadway following near the bottom ofPoggi Canyon. For this reason, it is the ideal spot for the Poggi Canyon Basin Sewer Interceptor. In addition, since none of East Orange Avenue has been constructed beyond the end of the existing I8-inch sewer in East Orange Avenue, the proposed Poggi Canyon Basin Sewer Interceptor can be constructed along with East Orange Avenue road improvements. Alternative alignments for the Poggi Canyon Basin Sewer Interceptor come into consideration through the existing developed Poggi Canyon Basta area, straddling the Interstate 805 freeway. Through this area three basic alignments were reviewed. These are described below: 1. Replacement. Replace the existing 8-inch gravity sewer in Oleander Avenue and is Melrose Avenue with the ultimate sized gravity sewer required for ultimate basin flows. 2. Parallel Alignment. Parallel the existing 8-inch gravity sewer in Oleander 26 6-139 Avenue and Melrose Avenue with the ultimate sized gravity sewer for the Poggi Canyon Basin. 3. Storm Drain Easement. Construct the ultimate size gravity sewer for the Poggi Canyon Basin within as existing storm drain easement, parallel to existing Oleander Avenue and Melrose Avenue. s,placement Alternative. This alternative would involve excavation and removal of the existing 8-inch gravity sewer line in Oleander Avenue and Mekose Avenue and replacement of that line with a larger diameter gravity sewer. It would involve asphalt cutting, removal, and pavement restoration, traffic control within an existing street, as well as providing temporary sewer service to existing homes on either side of the street while the construction was in progress. In addition, the existing sewer laterals would have to be tied to the new gravity sewer. Working in an existing street with traffic control increases the case of construction. In additioq removing and replacing the pipeline requires handling sewage flow from the existing house laterals on a temporary basis. While it can be accomplished, the process is time consuming as well as disruptive to the neighborhood in terms of noise, construction traffic, and dirt and debris. Parallel Aligpment. This alternative proposes to install the ultimate sized gravity sewer parallel to the existing 8-inch sewer in Oleander Avenue and Melrose Avenue. Under this alternative, the existing 8-inch sewer in Melrose Avenue sad Oleander Avenue would stay in place to act as a local collector sewer. All the existing homes would maintain their sewer lateral connections to the existing 8-inch sewer line. The new larger diameter Poggi Canyon Basis Sewer Interceptor would be connected to the existing 8-inch at critical points in order to relieve the 8-inch of ultimate basin flows. The construction of this parallel line would take place in the existing streets with asphalt cutting, removal and replacement as well as the similar disruption to the neighborhood from noise, construction traffic, dirt and debris as discussed under the replacement alternative. Construction would be simplified in not having to temporarily bypass existing sewer laterals 27 6-140 or reconnect them to the new pipeline. However, construction would be hampered by having to avoid existing sewer lateral crossings as well as avoiding other existing utilities within the existing streets. Generally, there appears to be sufficient room for a parallel gravity sewer within the existing streets. There maybe special construction required along segments due to clearances between the gravity sewer line and other wet or dry utilities. These would have to be better defined during a design level review of this alignment. This alternative may be more desirable than the replacement alternative. However, there may also be existing conditions within the existing roadways which may preclude the ability to parallel the existing S-inch sewer in both Oleander Avenue and Melrose Avenue. A review of these potential obstacles is beyond the scope of this report. Storm Drain Easement Alternative. A third alternative is to place the ultimate sized gravity sewer for the Poggi Canyon Basin within an existing storm drain easement which runs behind the homes fronting the west side of Oleander Avenue and Melrose Avenue. This storm drain easement contains a concrete lined storm water channel for storm water flows collected within the Poggi Canyon Basin. The easement includes a dirt roadway access bench in which it is possible to construct the ultimate sized gravity sewer for the basin. There are additional considerations which will have to be addressed with this alignment alternative. These include providing an enlazged access road for sewer maintenance vehicles and providing acceptable access points at either end of the alignment to permit City crews to easily maintain the sewer line. Special construction may also be necessary due to shallow depth of cover and existing storm drain crossings. Ia additioq construction access and working space may be limited particularly during the rainy season. These types of issues could increase the cost of this alternative. The existing 8-inch gravity sewer in Oleander Avenue and Melrose would be left in place to serve as a local collector sewer for the ultimate Poggi Canyon Basin Sewer Interceptor. Connections would be made at the upper end of Oleander Avenue and at Melrose Avenue near the intersection of Talus Street. This would provide relief to the existing 8-inch gravity sewers and allow them to continue to be used as a local sewer main. 28 6-141 As part of the Suabow II developmeat project, preliminary improvement plans have been prepared for this Alternative 3 alignment. These improvement glans demonstrate that it is feasible to construct the ultimate gravity sewer withir. the storm drain easement along the backside of the homes fronting the west side of Oleander Avenue and Meh•ose Avenue. The proposed alignment of the ultimate Poggi Canyon Basin Gravity Sewer Interceptor would extend south of Otay Valley Road within the storm drain easement to the proposed Reach 9 Regional Interceptor. Constructing the ultimata gravity sewer for the Poggi Canyon Basin within the storm drain easement might reduce construction costs due to much reduced traffic control requirements and reduced asphalt removal and restoration. It would likely be less disruptive to the neighborhood. However, io meet the.City's design criteria may entail additional costs, and the special construction constraints may increase the project costs. proposed AliEnment Alternative. As indicated eaziier in this section of the report, the Sunbow II project has been processing plans for the construction of the gravity sewer within the storm drain easement. The City has expressed some reservation that the storm drain easemeat alignmeat between Otay Valley Road and Melrose Avenue (beiweea Manhole 201 and Manhole 204 oa Exhibit A) is the most cost effective alignment. In order to protect its interests while allowing the project developer flexibility to exercise judgement as to which alternatives may be most cost effective, the City has agreed to accept the storm drain easement alignment, subject to the design being reviewed and approved by the Engineering Department, with a 5600,000 cap on the construction cost of this segmeat of the Poggi Canyon Basin Sewer. The project developer will not be reimbursed by either the Dff or the City for construction costs in excess of 5600,000. 29 6-142 CHAPTER 4 ANALYSIS A computer model was created for the Poggi Canyon Basin Sewer Interceptor System. This model extends from the upper portion of the basin at the boundary of Otay Ranch Village 5 and Eastlake Development, wesrand south to the interceptor's ultimate connection to the Reach 9 Regional Interceptor. The computer model diagram, including manhole numbers and reach numbers, is presented in Exhibit "A° attached to this report. In 'the preparation of the computer model, an attempt was made to keep it simple and minimize the number of gravity sewer reaches. The reaches were divided at points where there was a slope change and where a significant amount of sewage flow from any of the contributing properties is expected to be input. The gravity sewer slopes included in the model were obtained from a review of the Sunbow Tentative Map and tentative map for the Otay Ranch Village 1 and 5 project. These two sources were used to determine slopes is future East Orange Avenue. The slopes within the existing developed azea of the Poggi Canyon Basin were obtained from a review of the preliminary design drawings for the Sunbow R project offsite sewer system. ]n general, minimum anticipated gravity sewer line slopes were used in the computer model analysis. Verification of flow capacities for each reach of the Poggi Canyon Basin Sewer Interceptor should be made during the design phase of any portions of this interceptor. It may be possible that the final design of the interceptor based on actual scopes that can be achieved (which'may be greater than the slopes assumed in this study) may incorporate a decrease in the fine size of some of the reaches. Flows estimated from the future development prajecis within the Poggi Canyon Basin were input to the computer model at locations that best approximated their actual connection points based on the best available data for each of the projects. Existing flows were input 3Q 6-143 into the computer model by counting the actual EDUs which would be discharged into the Poggi Canyon Basin Sewer Interceptor at the computer modeled manholes. Table 4-i provides a summary of the average quantity of sewage flow entering each reach of the proposed Poggi Canyon Basin Sewer Interceptor.

Basin System Analysis. Exhibit "A", attached to the back of this report, provides a manhole number and reach diagram corresponding to the computer model. New Piae Sizing Anxlyie. Two scenarios were modeled with the computer system. The first scenario was to model the entire system based on a single family dwelling unit sewage generation rate of 280 gallons ger day per unit and amulti-family generation rate of Z10 gallons per day per unit. This scenario is the basis for the recommended line sizes for the Poggi Canyon Basin Sewer Interceptor. Table 4-2 provides a summary of the recommended gravity sewer line sizes for the Poggi Canyon Basin Sewer Interceptor on a reach by reach basis. Included in this table is a minimum slope estimated for each reach. This analysis included recalculating the size of the Reach 9 Regional Interceptor. This interceptor was originally sized in the Salt Creek Basin Gravity Sewer Analysis. The original sizing of the Reach 9 Regional Interceptor concluded that a 36-inch gravity sewer at a minimum slope of 0.23 percent is adequate for ultimate Salt Creek Basin flows. The Poggi Canyon Basin analysis shows that adding ultimate Poggi Canyon Basin flows to the Reach 9 Regional Interceptor will not require an increase in the size of the pipe. Under ultimate peak flows from both the Salt Creek Basin and the Poggi Canyon Basin, the 36-inch interceptor will flow out a depth of 0.75 D/d, or 27.0 inches of depth. No increase in pipe size is needed for the Poggi Canyon Basin flows unless the minimum pipe slope of 013 percent is not achievable. A double-check of the Reach 9 Irttaceptor sizing is provided below to assure that the appropriate peaking factor is being used.

The results of this scenario are printed out in Appendix E and show no change in the results for the required line sizes. Under both sewage flow generation scenarios, the existing 18-inch and 21-inch gravity sewer piping in Orange Avenue leading down to Oleander Avenue has sufficient capacity for ultimate basin flows. However, under both sewage flow generation scenarios, the existing 18-inch gravity sewer under the Interstate 805 freeway is shown to have insufficient capacity for ultimate basin flows. Therefore, this report recommends a replacement sewer under Interstate 805 to handle ultimate basin flows. Existing 18-inch IInder Interstate 805, The existing 18-inch sewer reach under the Interstate 805 freeway is shown as being under capacity even when using the lower 265/200 gpd/unit sewage generation factors. Even full-pipe capacity is not sufficient for peak ultimate flows. Appendix G provides calculations identifying the avai]able capacity, in EDUs, within the 18-inch sewer. Table 4-3 provides a summary of the results for various flow depth criteria. The total number of EDUs which are projected to flow through the 18-inch sewer are 12,834.3 EDUs. This number is based on 265 gpd/EDU. An alternative to replacing or paralleling the existing 18=inch sewer line under the freeway with a new 21-inch sewer is to allow it to surcharge during peak flows. Appendix H includes a calculation to estimate the amount of surchazge in the manhole and gravity sewer system on the upstream end (east end) of the 18-inch sewer reach under ultimate flow conditions. The results indicate that the backup in the proposed storm drain alignment sewer on the east side of the freeway would be approximately 80 feat. The backup in the existing 8-inch sewer would not be as dramatic. However, grease buildup and solids buildup could still occur resulting in increased maintenance on this reach of sewer line if it was not replaced. 39 6-152 TABLE 4-3 Available Capacity in Ezisting IS-lath Gravity Sewer Under I-805 Freeway (based on 265 gpd/EDU} II~'t~ ~ ' ~fsl'.~~s ~ ~~ ~~ufin~ilx~~ He~pt ~ingt"FD~IIs a s c <. ~« xv,k zro. -pS kXitd M < '~-s.S~Y xt„3e n.as~~a4 r ~ x t v. t"~',~'g`°zn~°~'£x s 2"YE~~'; `~ 3 k -a f'-...'h^ Y £~if t° P~l~r`IiJ.'^'~ _.: ,. 0.75 9,708 942 8,766 0.85 11,104 942 10,162 0.93 11,663 942 10,721 1.0 10,779 942 9,837 While the report recommends replacement in order to assure that the D.I.F. includes the necessary monies, it may be that as the basin approaches buildout, peak flows will be less than currently estimated. In that event, replacement would not be necessary. Monitoring of flow in this reach will assist in the final determination of whether or not the sewer should be replaced. It is not recommended that the sewer be allowed to surcharge regularly and significantly. Under such a scenario, replacement should be undertaken. Table 4-4 provides the unit construction costs which were used to prepaze the estimate of construction cost far the Poggi Canyon Basin improvements. Table 4-5 presents an estimate of construction costs for the recommeaded improvements for the Poggi Caayoa Basin Sewer Interceptor. The estimated costs for all reaches requiring improvement is S6,132,984. Note that four reaches of existing pipeline located in Orange Avenue, east of Oleander Avenue have sufficient capacity for ultimate design flows. However, Reach 205 which extends under Interstate 805 freeway has been shown to have insufficiem capacity for ultimate design flows. This report recommends a replacement 21-inch gravity sewer for this reach. 40 6-153 Revised costs fez the Reach 9 Regional Interceptor have not been calculated. The analysis within this report has determined that no increase in size of the Reach 9 Regional Interceptor is needed in order to accommodate u]timate Poggi Canyon Basin flows. Therefore, the costs for the Reach 9 Regional Interceptor as estimated in the Salt Creek Basin Gravity Sewer Analysis are still valid. The estimate of construction costs includes a 15 percent allowance for engineering, inspection services, and surveying, a 25 percent contingency, and a 2 percent allowance for City of Chula Ysta administrative costs. The unit costs used in Table 4-5 are estimated for ductile iron pipe and are based on a review of recent construction costs for similar type projects. These costs are based on an l:NR-CCI Index for Los Angeles of 6598 (April 1997).

The majority of the recommended sewer line will be installed in future East Orange Avenue. This is expected to occur concurrent with the construction of the road. Many sections of the existing gravity sewer west of Interstate 805 must be upsized for ultimate flows. There is some potential for these improvements to be constructed in phases. The following discussion provides the results of the phasing analysis performed for this study. Appendix I contains computer runs for the existing gravity sewer system west of Interstate 805. An exhibit in Appendix I shows the computer model diagram. The Sunbow II project is currently proposing to build the new Poggi Canyon Basin Sewer within the storm drain easement parallel to-and west of dleander Avenue and Melrose Avenue. A sewer reach over capacity in either of these streets would trigger the parallel ultimate gravity sewer to be built in the storm drain alignment. The computer runs in Appendix I provide the backup for the information presented here. The data is based on replacement of a reach when the existing reach flows full. Ia actual practice, the City should establish a lower threshold requirement to provide for a margin of safety. The existing system should not be subjected to surchazging prior to being replaced. Table 4-6 includes a summary of the number of additional EDUs which can be added to the existing system before certain reaches flow at full pipe. The analysis is dose based on 265 gpd/EDU. 43 6-156 TABLE 4-6 PLasing of Improvements in the Poggi Canyoa Basin West of Interstate 805 130 130 202 Construct Reaches 202, 203, and 204 to relieve sewer in Melrose Avenue. 209 79 201 Construct Reach 201, tie into existing 12-inch in Rancho Drive if Reach 9 Regional Interceptor is not built. 480 271 -- Build improvements to existing 12-inch in Raacha Drive between Reach 201 and Rios Avenue. 1,108 628 206 Construct Reaches 206 and 207 to relieve sewer in Oleander Avenue. ~ Based on 265 gpd/EDU. 44 6-157 CHAPTER 5 FINANCING Financing Through Sewer Benefit Area Fee The Developmem Impact Fee is calculated based on the total estimated cast of construction of the recommended improvements spread over the total number of future EDUs within the Poggi Canyon Sewer Basin requiring the facilities. Spreading the costs on an equivalent dwelling unit basis allows for assigning the share of costs in an equitable manner to all the land uses within the Poggi Canyon Basin Study Area. In Chapter 3, Table 3-Z provided a summary of ultimate EDUs for all the properties within the Poggi Canyon Basin Study Area. This summary of EDUs included existing development in the western portion of the Poggi Canyon Basin as well as some existing development within the Eastlake project. In order to establish the number of future EDUs within the Poggi Canyon Basin which will be used for determining the Development Impact Fee, we seed to subtract the existing EDUs within the basin. The following shows this calculation: Total EDUs within the Poggi Canyon Basin 13,505.3 Minus Existing EDUs in the Western Portion of the Poggi Canyon Basin -1,794.5 Minus Existing EDUs within the Eastlake Development -793.8 Total Future EDUs within the Poggi Canyon Basin I0,9I7.0 While the majority of the ultimate sewage flow being generated within the Poggi Canyon Basin is the result of future development, there are 2,588.3 existing EDUs within the basin which are not obligated to participate in the Poggi Canyon Basin Development Impact fee. Portions of the existing sewer system serving these EDUs will need to be upgraded to bandit ultimate flows of the new developments. The cost of improvements have been apportioned 45 6-158 between existing and new development based on their need for the new facilities. The City of Chula Vista will fund the upgrade of a portion of the existing system {see Table 5-1) with reserves that ware earmarked for the expansion of existing sewer systems. This will lower the fee burden on new residents and provide existing residents with a system that has an extended service life.

The development impact fee is based on the cost of required system improvements and the total future EDUs in the basin. The calculation for the Poggi Canyon Basin takes into account the City of Chula Vista participation in the cost for the required system upgrades. 46 6-159 A total of 10,917.0 EDUs comprise the future development within the Poggi Canyon Basin. The foilowing formula is used to determine the recommended improvement costs per EDU: Total Cost of Recommended Improvements Development Impact Fee = Total Future EDUs Total Cost of Recommended Improvements Needed for Future Development Development Impact Fee = 56,132,984 - 51,756,440 = $4,376,544 $4,376,544 _ _ $400.9 per EDU 10,917.0 EDUs Use $400 per EDU. This Development Impact Fee will be subject to an annual adjustment based on the Engineering News Record (ENR) Construction Cost Index for Los Angeles. The ENR-CCI for Los Angeles stood at 6598 in April 1997. The annual adjustment will also Lake into consideration actual construction costs, and changes in the type and density of development. Table 5-2 provides a summary of the Development Impact Fee calculated on a per EDU basis for the various land uses within the Poggi Canyon Basin. In this manner, the costs will be apportioned to the new developments proportional to their need for the sewer facilities.

SECTION 7. Due on Issuance of Building Permit. The Impact Fee shall be paid in cash upon the issuance of a building permit. Eazly payment is not permitted. No building permit shall be issued for development projects within the Territory unless the developer has paid the Impact Fee imposed by this Ordinance. SECTION 8. Determination of Equivalent Dwelling Units. Each single family detached dwelling or single family attached dwelling shall be considered one EDU for purposes of this Impact Fee. Each unit within amulti-family dwelling shall be considered 0.75 EDU. Every other commercial, industrial, non-profit, public or quasi-public, or other usage shall be charged at a rate calculated in accordance with the method for estimating EDUs set forth in Exhibit "B", Sewer Benefit Area Fees Based on Land Use Categories. SECTION 9. Time to Determine Amount Due; Advance Payment Prohibited. 6-349 Ordinance Page 4 The Impact Fee for each development shall be calculated at the time of building permit issuance and shall be the amount as indicated at that time and not when the tentative map or final map was granted or applied for, or when the building permit plan check was conducted, or when application was made for the building permit. SECTION 10. Purpose and Use of Fee. The purpose of the Impact Fee is to pay for the planning, design, construction and/or financing (including the cost of interest and other financing costs as appropriate) of the Facilities, or reimbursement to the City or, at the discretion of the City if approved in advance in writing, to other third parties for advancing costs actually incurred for planning, designing, constructing, or financing the Facilities. Any use of the Impact Fee shall receive the advance consent of the City Council and be used in a manner consistent with the purpose of the Impact Fee. SECTION 11. Amount of Fee; Amendment to the Master Fee Schedule The Impact Fee shall be calculated at the rate of $265 per EDU. Chapter XVI, Other Fees, of the Master Fee Schedule is hereby amended to add Section D, which shall read as follows: "D. Poggi Canyon Sewer Basin Development Impact Fee This section is intended to memorialize the key provisions of Ordinance No. 2716, and any amendments thereto, but said Ordinance govems over the provisions of the Master Fee Schedule, except with respect to changes permitted by resolution under Section 11 D(d). For example, in the event of a conflict in interpretation between the Master Fee Schedule and the Ordinance, or in the event that there are additional rules applicable to the imposition of the Impact Fee, the language of the Ordinance govems. a. Territory to which Fee Applicable. The area of the City of Chula Vista to which the Impact Fee herein established shall be applicable is set forth in Figure 2 of the Poggi Canyon Basin Gravity Sewer Development Impact Fee Update dated April, 2009, and is generally described as the Poggi Canyon Basin. b. Rate per EDU. The Impact Fee shall be calculated at the rate of $265 per EDU, which rate shall be adjusted from time to time by the City Council. c. EDU Calculation. 6-350 Ordinance Page 5 Each single family detached dwelling or single family attached dwelling shall be considered one EDU for purposes of this Impact Fee. Each unit within amulti- family dwelling shall be considered 0.75 EDU. Every other commercial, industrial, non-profit, public or quasi-public, or other usage shall be charged at a rate calculated in accordance with the method for estimating EDUs, attached as Exhibit "B", "Sewer Benefit Area Fees Based on Land Use Categories". d. When Payable. The Impact Fee shall be paid in cash not later than immediately prior to the issuance of a building permit." The City Council shall review the amount of the impact Fee annually or from time to time. The City Council may, at such reviews, adjust the amount of this Impact Fee as necessary to assure construction and operation of the Facilities. The reasons for which adjustments may be made include, but aze not limited to, the following: changes in the costs of the Facilities as may be reflected by such index as the Council deems appropriate, such as the Engineering-News Record Construction Cost Index (ENR-CCI); changes in the type, size, location or cost of the Facilities to be financed by the Impact Fee; changes in land use in the City's General Plan; other sound engineering, financing and planning information. Adjustments to the above Impact Fee may be made by resolution amending the Master Fee Schedule. SECTION 12. Authority for Accounting and Expenditures The proceeds collected from the imposition of the Impact Fee shall be deposited into a public facility financing fund ("Poggi Canyon Sewer Basin Benefit Area Fee Fund", or alternatively herein "Fund") which is hereby created and shall be expended only for the purposes set Forth in this ordinance. The Director of Finance is authorized to establish various accounts within the Fund for the Facilities identified in this ordinance and to periodically make expenditures from the Fund for the purposes set forth herein in accordance with the facilities phasing plan or capital improvement plan adopted by the City Council. SECTION 13. Findings Based on all written oral testimony at the hearing on the amendment to the Development Impact Fee, including the Report, the City Council hereby finds the following: A. The establishment of the Impact Fee is necessary to protect the public safety and welfare and to ensure the effective implementation of the City's General Plan. 6-351 Ordinance Page 6 B. The Impact Fee is necessary to ensure that funds will be available for the construction of the Facilities concurrent with the need for these Facilities and to ensure certainty in the capital facilities budgeting for growth impacted public facilities. C. The amount of the fee levied by this ordinance does not exceed the estimated cost of providing the Facilities for which the fee is collected. D. New development projects within the Territory will generate a significant amount of wastewater that current sewer facilities can not service, therefore construction of the Facilities will be needed to service new development projects. E. That there is a reasonable relationship between the need for the public facility and the type of development project on which the fee is imposed and the amount of the fee is roughly proportional thereto. SECTION 14. Impact Fee Additional to other Fees and Charges. The Impact Fee established by this section is in addition to the requirements imposed by other City laws, policies or regulations relating to the construction or the financing of the construction of public improvements within subdivisions or developments. SECTION I5. Mandatory Construction of a Portion of the Facilities; Duty to Tender Reimbursement Offer. Whenever a developer is required as a condition of approval of a development permit to construct or cause the construction of the Facilities or a portion thereof, the City may require the developer to install the Facilities according to design specifications approved by the City and in the size or capacity necessary to accommodate estimated ultimate flow as indicated in the Plan and subsequent amendments. If such a requirement is imposed, the City shall offer, at the City's option, to reimburse the developer from the Fund either in cash or over time as Fees are collected, or give a credit against the Impact Fee levied by this Ordinance or some combination thereof, in the amount of the costs incurred by the developer that exceeds their contribution to such Facilities as required by this Ordinance, for the design and construction of the Facility not to exceed the estimated cost of that particular Facility as included in the calculation and updating of the Impact Fee. The City may update the Impact Fee calculation as City deems appropriate prior to making such offer. This duty to offer to give credit or reimbursement shall be independent of the developer's obligation to pay the Impact Fee. SECTION 16. Voluntary Construction of a Portion of the Facilities; Duty of City to Tender Reimbursement Offer. If a developer is willing and agrees in writing to design and construct a portion of the Facilities in conjunction with the prosecution of a development project within the Territory, the City may, as part of a written agreement, reimburse the developer from the Fund either in cash or over time as Fees aze collected, or give a credit against the Impact 6-352 Ordinance Page 7 Fee levied by this Ordinance or some combination thereof, in the amount of the costs incurred by the developer that exceeds their contribution to such Facilities as required by this Ordinance, for the design and construction of the Facility not to exceed the estimated cost of that particular Facility as included in the calculation and updating of the Impact Fee and in an amount agreed to in advance of their expenditure in writing by the City. The City may update the impact Fee calculation as City deems appropriate prior to making such offer.
