PAGE 3 The Nakano project will receive water service from the City of San Diego Water Department and will be located within the 365 Pressure Zone. Purpose of Study and Water System Design Criteria The purpose of this study is to analyze and determine if the existing public water system is able to provide adequate domestic and fire protection service for the Nakano project. This report will address if any offsite (public) City of San Diego water system improvements are needed for the development of the project so that the offsite water system will be in conformance with the City of San Diego Water Department water system design standards. The City of Chula Vista and City of San Diego annexation procedures and ultimate determinations for the Nakano project will have no impact to the water supply and connection points presented in this study. A summary of the City of San Diego Water Department design criteria from Book 2 is presented as Table 1. TABLE 1 CITY OF SAN DIEGO WATER DEPARTMENT WATER SYSTEM DESIGN CRITERIA Criteria Design Requirement Single-Family Residential (up to 4-plex) Fire Flow 1,500 gpm Condominiums and Apartments Residential Fire Flow 3,000 gpm Minimum Static Pressure 65 psi Maximum Static Pressure 120 psi Maximum Pressure Drop – Domestic Pressure 25 psi Minimum Pressure – Domestic Pressure 40 psi Minimum Pressure – Max Day plus Fire 20 psi Maximum Pipeline Velocity (Fire Flow) 15 fps Maximum Pipeline Velocity (Normal Operating Conditions) 5 fps April Tornillo, P.E. June 21, 2022 Nakano Water System Analysis DEXTER WILSON ENGINEERING, INC. PAGE 4 Water service internal within the Nakano project will consist of two separate private water systems; one will be for private domestic water service and the other will be for private fire protection service. The domestic water system is sized in accordance with the California Plumbing Code 2019. The fire protection component of the water system is designed based on the required fire flow for the project as dictated for residential land use. The City of San Diego Water Department requires a 1,500-gpm fire flow for single family residential and a 3,000-gpm fire flow for multi-family residential (> 4-plex). The California Fire Code also establishes fire flow requirements. The fire code takes into account building area and construction type. The largest building proposed for the project site is not finalized/established yet at time of this report. The worst-case fire flow requirement expected per the 2019 California Fire Code is 4,000 gpm. After the reduction of 25% for an approved fire sprinkler system stated by the City of Chula Vista, the expected worst-case fire flow requirement for the project site would be 3,000 gpm. Appendix A presents the City of San Diego Water Department guidelines and design criteria as well as the excerpt from the 2019 California Fire Code pertaining to fire flow requirements. Additionally, the private fire protection system is designed to provide a minimum residual pressure greater than 20 psi at any location within the private fire protection water system under a fire flow demand. Study Area and Existing Water System The study area for this report is the boundary of the Nakano project and the water system surrounding the project. The extent of the existing water system which was incorporated into the analysis of the project site was based on the existing 365 Zone distribution system that serves the area. The Nakano project is within the City of Chula Vista and will obtain water service from the City of San Diego’s public water system. The nearest existing public water line in the vicinity April Tornillo, P.E. June 21, 2022 Nakano Water System Analysis DEXTER WILSON ENGINEERING, INC. PAGE 5 of the Nakano project is a 12-inch diameter water line in Dennery Road. There are 42-inch diameter transmission lines in Dennery Road as well, however, they are in the 490 Zone. Nakano Project Water Demand The water demands were developed in accordance with the City of San Diego Water Department Design Guidelines and Standards. Residential water demand is estimated based on density and a unit water demand of 150 gpd/person. The Nakano project proposes 221 residential units over 19.04 net acres equaling 11.6 units per acre. Table 2-1 in the City of San Diego Water Department Design Guidelines and Standards, attached as Appendix A, indicates that 11.6 units per acre falls in the range of 3.5 persons per dwelling unit. A dwelling unit density of 3.5 persons per dwelling unit and a unit water demand of 150 gpd/person results in a water demand rate of 525 gpd per dwelling unit at the project. Table 2 presents the projected potable water demand for the Nakano project. TABLE 2 NAKANO PROJECT POTABLE WATER DEMAND Land Use Quantity Demand Factor Average Water Use, gpd Residential (11.6 DUs/net acre) 221 Units 525 gpd/DU 116,025 TOTAL 116,025 = 80.6 gpm From the City of San Diego Water Department Guidelines and Standards, Figure 2-2, the maximum day demand to average annual demand ratio is approximately 1.7 based on the RS residential peaking curve, resulting in an estimated maximum day demand of 197,243 gpd (137 gpm). April Tornillo, P.E. June 21, 2022 Nakano Water System Analysis DEXTER WILSON ENGINEERING, INC. PAGE 6 From the City of San Diego Water Department Guidelines and Standards, Figure 2-1, the peak hour demand to average annual demand ratio is approximately 3.1 based on the RS residential peaking curve, resulting in an estimated peak hour demand of 359,678 gpd (250 gpm). Appendix A of this report presents the backup data for determining these peaking factors. Water Service Overview Water service to the Nakano project will be provided by constructing a new 12-inch diameter 365 Zone public water line in Dennery Road from the existing water regulating station at Sand Star Way up to the project frontage/entrance driveway. This new 12-inch diameter public water line will need to tie in to the existing 12-inch diameter public water line east of the supply lateral from the existing water regulating station at Sand Star Way. The range of pad elevations on the project, 111 to 119 feet, results in expected maximum static pressures at the street to be between 107 psi and 110 psi. The private domestic water system for Nakano will consist of installing a new domestic service lateral and setting a new domestic meter and backflow preventer for the lot. Sizing of the private domestic water system will be discussed in more detail later in this report. The private fire protection system will consist of two 8-inch diameter fire service laterals extending off of the new and existing 12-inch diameter public water lines in Dennery Road. An 8-inch reduced pressure principle detector check assembly will be installed at the project boundary at both connections to the public system, and internal to the project there will be 8-inch private fire protection piping to provide service to the seven onsite private fire hydrants. Fire sprinkler water lines and laterals, which are expected to be connected to the private fire protection system and will supply the individual residence fire sprinkler system, shall be sized by the fire sprinkler system designer employed for the Nakano project and are outside the scope of work for this report. April Tornillo, P.E. June 21, 2022 Nakano Water System Analysis DEXTER WILSON ENGINEERING, INC. PAGE 7 Available Hydraulic Grade Line The available hydraulic grade line (HGL) in the vicinity of the Nakano project was obtained from the City of San Diego Public Utilities Department Water Field Book. The pertinent sheets from the Water Field Book are included in Appendix A of this report. According to the Water Field Book, the two existing water regulating stations feeding the 365 Zone consist of 10-inch pressure reducing valves which corresponds to a maximum flow of 4,900 gpm each. The City of San Diego Water Department typically sets the larger valve approximately 10 psi less than the smaller valve at water regulating stations which would equate to an available HGL of 341 feet at the existing water regulating stations in the project vicinity. A hydraulic control map illustrating the pressure zone boundaries in the area is presented as Figure 2. Private Domestic Water System Private domestic water service to the Nakano project will be provided through a master meter. This domestic water meter is preliminarily sized based on the California Plumbing Code. The California Plumbing Code uses Water Fixture Units as a basis for determining maximum domestic flow. The preliminary sizing of the project’s master water meters and private domestic water system is summarized below as well as in Appendix B. For the Nakano project, the California Plumbing Code estimates the maximum domestic flow to be approximately 820 gpm based on a conservative count of Water Fixture Units based on the proposed residential product types. The city of San Diego Water Department uses 80 percent of the AWWA meter rating as their maximum allowable flow rate. A 6-inch meter has an AWWA rated capacity of 1,350 gpm, which means the maximum flow rate allowed by the city of San Diego for a 6-inch meter is 1,080 gpm. As this is still higher than the estimated demand for Nakano of approximately 820 gpm, a single 6-inch meter is sufficient for Nakano. The City of San Diego Water Department, however, also has a policy of installing two parallel meters whenever the peak flow rate exceeds the capacity of a 2-inch meter. Thus, for this project which needs a single 6-inch meter, the Water Department will instead install two 4- inch meters in parallel. Although there will be two meters, there will only be a single 6-inch public water service lateral that will then split into the two 4-inch meters with each meter being followed by a 4-inch reduced pressure principle backflow preventer. April Tornillo, P.E. June 21, 2022 Nakano Water System Analysis DEXTER WILSON ENGINEERING, INC. PAGE 9 The proposed 6-inch domestic water service lateral will be connected to the proposed 12-inch 365 Zone water line in Dennery Road. Domestic Water System Pipe Sizing. The private domestic water system distribution piping for the Nakano project has been preliminarily sized in accordance with the Uniform Plumbing Code and the Installation Standard for PVC Cold Water Building Supply and Yard Piping (IAPMO IS 8-2006). The Installation Standard requires that the maximum pipeline velocity be limited to eight feet per second (8 fps). Figure 3 presents a graphic of the recommended private domestic water system for the project. Individual residence supply piping is to be sized to match the plumbing plans for the size of the domestic water entering the single buildings. The domestic water line sizes shown on Figure 3 are the minimum recommended pipe sizes that comply with the California Plumbing Code and will supply adequate flow and pressure within the Nakano project. The line sizes may be increased for uniformity or ease of construction. Private Fire Protection System Pipe Sizing All fire hydrants within the Nakano project will be connected to a private fire protection water system which will be independent of any other water system. The private fire protection system for Nakano will have one connection to the new 12-inch public water line and one connection to the existing 12-inch public water line in Dennery Road. The private fire protection system was sized based on the required fire flow for the project and taking into consideration the proposed piping configuration. In order to establish the required fire protection system pipe sizing, a water system computer model was generated for the project’s fire protection system piping. Fire flow scenarios were modeled which provided data upon which the recommended pipe sizing is based. April Tornillo, P.E. June 21, 2022 Nakano Water System Analysis DEXTER WILSON ENGINEERING, INC. PAGE 11 Model Development. Analysis using the KYPIPE computer software program developed by the University of Kentucky determined residual pressures throughout the fire protection system. This computer software utilizes the Hazen-Williams equation for determining headloss in pipes. The Hazen-Williams “C” value used for all pipe sizes in our analysis is 120. Fitting and Valve Losses. To simulate minor losses through pipe fittings and valves, “K” values were added to the pipe segments and included in the hydraulic model. Backflow Assembly Losses. The pressure losses through the reduced pressure principle detector check assembly devices were modeled as losses inputting a loss curve which simulates the expected pressure loss through these devices. Appendix C presents a candidate reduced pressure principle detector check assembly backflow preventer device. The manufacturer’s literature includes charts which show pressure loss through the backflow preventer as a function of flow. These charts were used to approximate the pressure losses which were reflected in the computer modeling. Hydraulic Grade Line Available. The private fire protection system was modeled with an estimated hydraulic grade line at each of the existing water regulating stations of 341 feet. These locations are along Dennery Road at Sand Star Way and Black Coral Way respectively. This hydraulic grade line was obtained using the City of San Diego Public Utilities Department Water Field Book as described earlier in this report. The private fire protection system has been designed to provide a minimum residual pressure greater than 20 psi under a fire flow scenario within the Nakano project. Fire Protection System Analysis. Appendix D presents the computer modeling results for the private fire protection system. Exhibit A at the end of Appendix D shows the Node and Pipe Diagram for the private fire protection system. The fire flow requirements of 1,500 gpm and 3,000 gpm was modeled at all pertinent fire hydrant locations. The existing public water system is not able to supply the required fire hydrant flow due to lack of redundancy. The recommendation is to construct a new parallel 12-inch diameter water main in Dennery Road from the existing water regulating station at Sand Star Way to April Tornillo, P.E. June 21, 2022 Nakano Water System Analysis DEXTER WILSON ENGINEERING, INC. PAGE 12 the project entrance driveway. This parallel water main will enable the fire flow requirement for the Nakano project to be met in spite of potential pipe breaks. As a conservative approach, this proposed parallel 12-inch diameter water line was not included in the hydraulic model. With the proposed 12-inch public water main improvement in Dennery Road, the fire flow requirement is being met with greater than 20 psi residual pressure at all locations within the project. Minimum residual pressures are greater than 43 psi under all fire flow scenarios. The private fire protection system will be connected to the new 12-inch public water line and to the existing 12-inch public water line in Dennery Road as shown in Figure 3 and Exhibit A. Each of the two connections includes an 8-inch lateral and an 8-inch reduced pressure principle detector check assembly in accordance with the City of San Diego Water Department standards and the City of Chula Vista Backflow Prevention Department requirements (if applicable). The City of Chula Vista Fire Department requirements for fire hydrants, fire hydrant locations, fire department connection (FDC) locations, post indicator valves (PIV), and other standard details can be found at: http://www.chulavistaca.gov/departments/fire-department/about-cvfd/fire-prevention/forms- details Conclusions and Recommendations The following conclusions and recommendations are summarized based upon the water system analysis performed for the Nakano project. 1.

APPENDIX A CITY OF SAN DIEGO WATER DEPARTMENT GUIDELINES AND DESIGN CRITERIA, CA FIRE CODE EXCERPT, AND EXISTING WATER INFORMATION Chapter 2: Water Demands and Service Criteria City of San Diego Public Utilities Department 2-1 Water Facility Design Guidelines January 2021 WATER DEMANDS AND SERVICE CRITERIA 2.1 General This chapter outlines planning procedures to estimate water demands and fire flows. Water system service requirements are also defined in terms of water pressure and reservoir storage. 2.2 Service Area The DESIGN CONSULTANT defines the project’s service area and identifies the pressure zones in which it is located. The Senior Civil Engineer in charge of either Water Planning or new development approves the service area boundaries. 2.3 Land Use and Residential Population The DESIGN CONSULTANT develops present and future land use maps for the service area to define the following land use categories: residential (by zone in accordance with Table 2-1), central business district, commercial and institutional, parks, hospitals, hotels, industrial, office, and schools. The DESIGN CONSULTANT estimates the residential population in the service area based on present and future allowable land use. Unless more accurate population density estimates are available, the residential population in the service area is estimated based on the figures presented in Table 2-1. Table 2-1 Residential Population Density Zone Dwelling Unit Density (dwelling unit/ net acre) Unit Density (persons/ dwelling unit) Population Density (persons/ net acre) AR-1-1 0.1 3.5 0.4 AR-1-1 0.2 3.5 0.7 AR-1-2 1 3.5 3.5 RS-1-1/RS-1-8 1 3.5 3.5 RS-1-2/RS-1-9 2 3.5 7.0 RS-1-4/RS-1-11 4 3.5 14 2 Chapter Chapter 2: Water Demands and Service Criteria City of San Diego Public Utilities Department 2-2 Water Facility Design Guidelines January 2021 Zone Dwelling Unit Density (dwelling unit/ net acre) Unit Density (persons/ dwelling unit) Population Density (persons/ net acre) RS-1-7/RS-1-14 9 3.5 32 RM-1-1 14 3.2 45 RM-2-5 29 3.0 87 RM-3-7 43 2.6 112 RM-3-9 73 2.2 161 RM-4-10 109 1.8 196 RM-4-11 218 1.5 327 Dwelling unit density in Table 2-1 is based on net area. The net area is measured in acres, and is 80% of the gross area for each residential zone. 2.4 Average Annual Water Demands For most projects, average annual water demands are determined based on the unit water demand criteria presented in Table 2-2. Table 2-2 Unit Water Demands Land Use Category Unit Water Demand Residential 150 gallons/person-day Central Business District 6000 gallons/net acre-day Commercial and Institutional 5000 gallons/net acre-day Fully Landscaped Park 4000 gallons/net acre-day Hospitals 22500 gallons/net acre-day Hotels 6555 gallons/net acre-day Industrial 6250 gallons/net acre-day Office 5730 gallons/net acre-day Schools 4680 gallons/net acre-day Average annual water demands are calculated as the sum of: (1) the residential water demand, and (2) other water demands for each land use category as follows: Residential Water Demand (gallons/day) = Residential Population x 150 gallons/person-day Chapter 2: Water Demands and Service Criteria City of San Diego Public Utilities Department 2-3 Water Facility Design Guidelines January 2021 Other Water Demand (gallons/day) = Land Use Area by Category (net acres) x Unit Water Demand for Each Land Use Category (gallons/net acre-day) Average Annual Water Demand (gallons/day) = Residential Water Demand + Other Water Demands On some projects, particularly large residential developments, using the unit water demands in Table 2-2 may generate unrealistically high estimates of water requirements. For these large projects, the DESIGN CONSULTANT or developer may request that the Senior Civil Engineer consider an alternative approach, making use of the City’s water demand distribution data developed for macroscale planning purposes. Similarly, the Senior Civil Engineer may also consider alternative unit water demand estimates for specific land use types where such estimates are based on detailed demand evaluations. Recent projects of similar size, nearby location and similar character may be used for comparative demand analysis. 2.5 Peak Water Demands Unless the project involves a large development that calls for an alternative approach, peak hour and maximum day water demands are estimated using the peaking factors presented in Figures 2-1 and 2-2. Peaking day factors correspond to the zones identified in the Public Utilities Department Water System HGL Zones. Peak water demands are estimated as follows: Peak Hour Demand = Average Annual Water Demand * Peak Day Factor * 1.5 Maximum Day Demand = Average Annual Water Demand * Peak Day Factor Ch a p t e r 2 : W a t e r D e m a n d s a n d S e r v i c e C r i t e r i a Ci t y o f S a n D i e g o Pu b l i c U t i l i t i e s D e p a r t m e n t 2 - 4 Wa t e r F a c i l i t y D e s i g n G u i d e l i n e s Ja n u a r y 2 0 2 1 Ch a p t e r 2 : W a t e r D e m a n d s a n d S e r v i c e C r i t e r i a Ci t y o f S a n D i e g o Pu b l i c U t i l i t i e s D e p a r t m e n t 2 - 5 Wa t e r F a c i l i t y D e s i g n G u i d e l i n e s Ja n u a r y 2 0 2 1 Chapter 2: Water Demands and Service Criteria City of San Diego Public Utilities Department 2-6 Water Facility Design Guidelines January 2021 2.6 Fire Demands The DESIGN CONSULTANT shall use the minimum required fire demands for design shown in Table 2-3. The fire flow duration for planning purposes is at least five hours. Note that the values in Table 2-3 are the minimum design criteria for public infrastructure. Privately owned facilities shall follow the guidelines described in Appendix B of the California Fire Code (CFC). Table 2-3 Fire Demands for Design Purposes Development Type Fire Demand (gpm) Single family residential up to Fourplexes 1,500 Condominiums and apartments 3,000 Commercial 4,000 Industrial 6,000 Should application of the CFC Appendix B result in figures lower than those shown in Table 2-3, the firm or Civil Engineer, in consultation with the fire department, CIP City Project Manager may approve the CFC figures on a case-by-case basis following submittal of supporting calculations. In no case shall the approved fire flow rate and flow duration be less than the flow rate and duration values required by Appendix B of the CFC based on the anticipated or proposed type of building construction and total building floor area. The required fire demand must be supplied from public and private on-site fire hydrants located as required by CFC Appendix C. 2.7 Pressure Criteria 2.7.1 Design Pressures Water systems must be designed to provide the minimum residual pressures under:  Maximum day demands plus fire demand conditions, or  Peak hour demand conditions. In analyzing the supply to a pressure zone, the minimum hydraulic grade line elevation available from the water source is used, a level that typically occurs during dry weather conditions. A water supply source is defined as a treatment plant clearwell, flow control facility, pump station, pressure regulating station or reservoir. Supply sources occur at discrete points in a system of Chapter 2: Water Demands and Service Criteria City of San Diego Public Utilities Department 2-7 Water Facility Design Guidelines January 2021 water mains and control both flow and pressure at the supply point. Water mains are not supply sources but rather conveyance facilities. The maximum static pressure in gravity systems is determined from reservoir overflow elevations and/or the discharge control setting on pressure reducing valves, whichever is greater. The maximum static pressure in pumped systems is determined from reservoir overflow elevations or pump shutoff levels, whichever is greater. There are two important pressure criteria used in water system design: Domestic Pressure and Fire Pressure. For systems supplying only domestic demand, only the Domestic Pressure criteria will apply. Similarly, for systems providing only fire demand, only the Fire Pressure criteria will apply. Systems supplying both types of demand, both criteria will apply and must be independently checked. 2.7.2 Domestic Pressure Criteria The domestic pressure criteria for water system design are shown in Figure 2-3. Every water main in each pressure zone must be capable of supplying a minimum static pressure of 65 psi. Domestic pressures must fall no more than 25 psi below the static pressure, and residual water main pressure must be at least 40 psi. Domestic pressures are determined in the distribution system pipelines, excluding losses through service connections and building plumbing, and are measured relative to adjacent building pad elevations. When analyzing a system with one source of supply out of service, domestic pressures may fall more than 25 psi below static pressure, but the domestic pressure shall not fall below 40 psi. 2.7.3 Pressure Requirements During Fires For the simulation of fire conditions, a minimum operating pressure of 20 psi is required at the fire hydrant locations.. The residual pressure is determined given the fire demand among one or more hydrants and with the simultaneous water consumption occurring at the maximum day demand. The hydrants considered in this simulation must be sufficiently near to the fire location to be classified as “available” to that location as defined by the California Fire Code. For water systems with available storage, the residual pressures in the distribution system during a fire are maintained given the following conditions: The water level in the storage facility at the time of the fire is at or near the minimum operating level The prescribed fire duration set by the California Fire Code, occurring under maximum day conditions. 2.8 System Reliability Water systems must be designed to meet the operating pressure criteria with one critical source Chapter 2: Water Demands and Service Criteria City of San Diego Public Utilities Department 2-8 Water Facility Design Guidelines January 2021 out of service. Water mains must be designed so that no more than one, average-sized city block (approximately 30 homes) is out of service at any time, and no more than two fire hydrants (excluding fire services) are on a dead end or are out of service at any time. These provisions do not apply under earthquake conditions. Water mains serving more than two hydrants or more than 30 homes must be looped, fed from two sources, or provided with a reservoir of sufficient capacity to supply the emergency needs (contingency and fire storage) as described below in subsection 2.9. All water mains relied upon for looping and source redundancy shall be in separate streets. Dual mains in the same street or alignment require the DESIGN ENGINEER to prepare a request for deviation using the format of ATTACHMENT 1, which is included as a part of this document. Where dual mains are relied upon for looping or source redundancy, the mains shall be spaced at least 10 feet apart from outer edge to outer edge. For City CIP work in already-built-out areas, where looping of mains or connection to two sources of supply is not feasible, water mains may be constructed require the DESIGN ENGINEER to prepare a request for deviation using the format of ATTACHMENT 1, which is included as a part of this document.

For more information, send for literature ES-WB. How it operates The unique relief valve construction incorporates two channels: one for air, one for water.When the relief valve opens, as in the accompanying air- in/water-out diagram, the right-hand channel admits air to the top of the reduced pressure zone, relieving the zone vacuum.The channel on the left then drains the zone to atmosphere.Therefore, if both check valves foul, and simultaneous negative supply and positive backpressure develops, the relief valve uses the air-in/water-out principle to stop potential backflow.
