PAGE 3 Water System Design Criteria The design criteria used in sizing the water distribution system piping for the Marja Acres project are consistent with the City of Carlsbad Engineering Standards, Volume 2, Potable and Recycled Water Standards, 2016 Edition. Appendix A includes an excerpt of the first portion of Chapter 3 which includes the City’s potable water design criteria. The design criteria is also summarized below in Table 1. TABLE 1 CITY OF CARLSBAD WATER SYSTEM DESIGN CRITERIA Criteria Design Requirement Single-Family Residential Fire Flow 1,500 gpm Multi-Family Residential Fire Flow 3,000 gpm Commercial Fire Flow 4,000 gpm Minimum Static Pressure 60 psi Maximum Static Pressure 125 psi Minimum Pressure – Peak Hour 40 psi Minimum Pressure – Max Day plus Fire Flow 20 psi Maximum Pipeline Velocity (Peak Hour Demand) 10 fps Residential Average Day Demand 550 gpd/SF Unit 250 gpd/MF Unit Non-Residential Average Day Demand 2,300 gpd/10,000 sq. ft. Maximum Day Demand Peaking Factor 1.65 Peak Hour Demand Peaking Factor 2.90 Projected Water Demand The expected water demand for the Marja Acres project was estimated using water demand criteria from the City’s Engineering Standards. Table 2 below presents the estimated onsite water demand for the project. Jesse Kleist April 12, 2023 DEXTER WILSON ENGINEERING, INC.

Maximum day demand for the Marja Acres project is 125,070 gpd (87 gpm). The peak hour demand is 219,820 gpd (153 gpm). The peak recycled water demand is based on the peak irrigation water demands. This was stated to be 200 gpm by the project’s landscape architect. An e-mail correspondence confirming the 200 gpm peak demand is included in Appendix A. Fire Flow Requirements The fire flow requirement for the Marja Acres project is based on the City Engineering Standards. This requirement is 3,000 gpm split between any two fire hydrants for multi- family residential and 4,000 gpm split between four hydrants for commercial areas. This fire hydrant flow requirement is analyzed under a Maximum Day Demand scenario. Residual pressures in the water system under a fire flow scenario must be 20 psi or greater. Jesse Kleist April 12, 2023 DEXTER WILSON ENGINEERING, INC. PAGE 5 Existing Water System The Marja Acres project is within the City of Carlsbad and will obtain water service from the Carlsbad Municipal Water District’s public water system. The nearest existing public potable water line in the vicinity of the Marja Acres project is a 12-inch 241 Zone water line in El Camino Real. There are also existing 490 and 446 Zone public water lines in the vicinity of the project. Note that the 241 Zone in the City is also referred to as the 255 Zone. For the purposes of this report, and to be conservative in the hydraulic calculations, the pressure zone will be referred to as the 241 Zone. There are existing recycled water lines adjacent to the project as well. The 384 Zone in the District’s recycled water system was extended in El Camino Real northward from Cannon Road from previous projects in Marja Acres’ vicinity. Water Service Overview The Marja Acres project is proposing to obtain potable water service from the existing 241 Zone system. This will be accomplished by establishing five connections off of the existing 12-inch 241 Zone pipeline in El Camino Real. This will provide a looped domestic water system through the project site for the residential portion and a single service for the commercial portion. The onsite water systems are proposed as private systems. The domestic water systems will be separately metered at the points of connection at El Camino Real. The proposed onsite layout is shown on Figure 2. The approximate range of elevations on the project, 60 to 89 feet, results in expected maximum static pressures to be approximately between 65 and 78 psi. The planned recycled water uses for Marja Acres include irrigation of the common areas, the community recreation area, and proposed slopes. The existing and proposed recycled water system is shown on Figure 3. (EV)(EV)EV EV (EV)(EV) (EV)(EV)EV EV (EV)(EV) Jesse Kleist April 12, 2023 DEXTER WILSON ENGINEERING, INC. PAGE 8 Private Domestic Water Service. A water fixture unit (WFU) count based on architectural and plumbing plans was performed to estimate the water meter size. By utilizing the 2022 California Plumbing Code, a WFU count can be equated to a peak flow rate in gpm which, in turn, can be used to recommend a water meter size. The project’s architectural and mechanical plumbing plans were utilized for each area to confirm the WFU count. The plumbing plans are attached within Appendix B. Table 3 below presents the WFU count and resultant peak flow rate and meter size for each project area. TABLE 3 MARJA ACRES WFU SUMMARY Area WFUs Peak Flow Rate Water Meter Size Residential - Townhomes 8,067 852 gpm (8,562 WFUs total) Two 3-inch Residential - Apartments 495 Commercial 21 35 gpm One 1-inch The peak flow rate in Table 3 differs with the peak hour demand presented after Table 2 earlier in this report as the WFU method is primarily reserved for meter sizing and takes a more conservative approach in calculating peak domestic water demand. The private water information and background for Marja Acres is included in Appendix B of this report. The final recycled water meters and backflow size is undetermined at this time but will likely be two 2-inch to independently accommodate the 200 gpm peak irrigation demand. Private Fire Protection System Service. The private fire protection system for Marja Acres consists of 8-inch laterals stemming off El Camino Real and 8-inch diameter distribution piping throughout the project site. Jesse Kleist April 12, 2023 DEXTER WILSON ENGINEERING, INC. PAGE 9 Private Water System Pipe Sizing The private onsite water system piping for the Marja Acres project has been sized in accordance with the required water demands of the distribution system. The recommended private water system for the Marja Acres consists of 8-inch and 4-inch diameter water lines downstream of the reduced pressure principle backflow preventers. The onsite private water systems are also analyzed and confirmed via a hydraulic computer model. This is described in a later section of this study. Figure 2 presents a graphic of the recommended private water line sizes for the project site. Available Hydraulic Grade Line The available hydraulic grade line (HGL) for the potable water 241 Pressure Zone supplying the Marja Acres project is set at 241 feet HGL by the 1.5 million-gallon Skyline Tank at the intersection of Hillside Drive and Skyline Road. Additional data which provides available pressure in the public water system adjacent to the Marja Acres project is a fire flow analysis prepared by the City of Carlsbad. This Water Availability Form identifies a flow and pressure at a given existing fire hydrant on the existing public water system via a computer model simulated hydrant flow test. This Water Availability Form is provided in Appendix C. How this is used in the hydraulic analysis for the Marja Acres site will be discussed later in this report. The available hydraulic grade line (HGL) for the recycled water 384 Pressure Zone supplying the Marja Acres project is stated to be 120 psi (~335 HGL) in El Camino Real adjacent to the project per the City’s 2019 Recycled Water Master Plan. The excerpt in the City’s 2019 Recycled Water Master Plan is included in Appendix A. Jesse Kleist April 12, 2023 DEXTER WILSON ENGINEERING, INC. PAGE 10 Water System Computer Model The University of Kentucky KYPIPE program was used to create a computer model of the existing and proposed water system for the Marja Acres project. This computer program utilizes the Hazen-Williams equation for determining head-loss in pipes; the Hazen-Williams "C" value used for all pipes is 120. Fire Flow Analysis and Water System Computer Model Available Pressure. A fire hydrant flow test was conducted adjacent to the project site to determine the available hydraulic grade line. At a static pressure of 83 psi and hydrant elevation of 50 feet, the available static hydraulic grade line is calculated to be 241 feet. During a fire flow of 3,550 gpm the residual pressure at the hydrant test location is 79 psi. This location also was chosen as the source of the water model. Making the test hydrant the location of the water model source allows for a more accurate calculation of the HGL in the vicinity of the project. Utilizing the hydrant flow test and extrapolation calculation, an HGL of approximately 234 feet was determined for a 3,000-gpm fire flow condition and 230 feet was determined for a 4,000-gpm fire flow condition. This was inputted as a variable pressure source in the hydraulic model. A copy of the hydrant flow test and corresponding extrapolation calculation table is included in Appendix C. The location of the test hydrant in the Water Availability Form is along El Camino Real adjacent to the project. This location was also chosen as the source of the water model. Making the test hydrant the location of the water model source allows for a more accurate calculation of the HGL in the vicinity of the project. Fitting and Valve Losses. To simulate minor losses through pipe fittings and valves, minor loss coefficients, or “k” values, for all fittings associated with pipes were included in the hydraulic model. Jesse Kleist April 12, 2023 DEXTER WILSON ENGINEERING, INC. PAGE 11 Meter and Backflow Assembly Losses. The meter and backflow preventer devices were modeled as loss element nodes. A loss element node uses a flow-versus-pressure-loss curve to determine the pressure loss at a given flow. Appendix B presents the specified combined water meter and a candidate reduced pressure backflow preventer device. The manufacturer’s literature includes charts which show pressure loss through the meter and backflow preventer as a function of flow. These charts were used to approximate the pressure losses which were reflected in the computer modeling and show up as minor losses calculated in feet. Computer Model Analysis – Domestic Water System Computer modeling of the proposed onsite private domestic system and existing offsite water system for the Marja Acres project was performed to confirm the pipe sizes necessary to provide adequate domestic service. The water system was analyzed under two scenarios: average day demand and peak hour demand. Appendix D provides the results of the computer modeling for the analyzed water system. Exhibit A at the back of Appendix D provides the Node and Pipe Diagram for the computer model. The results in Appendix D show that the proposed water system for the Marja Acres project is adequate for domestic service. The results of the computer model show that average day demand can be achieved onsite with a minimum residual pressure of 56 psi and that peak hour demand can be achieved onsite with a minimum residual pressure of 53 psi. Computer Model Analysis – Fire Protection System Computer modeling of the proposed onsite private fire protection system and existing offsite water system for the Marja Acres project was performed to confirm the pipe sizes necessary to provide adequate fire protection service. The water system was analyzed under two fire Jesse Kleist April 12, 2023 DEXTER WILSON ENGINEERING, INC. PAGE 12 flow scenarios: an onsite maximum day demand plus 3,000 gpm scenario across two hydrants and an onsite maximum day demand plus 4,000 gpm scenario across four hydrants. Appendix E provides the results of the computer modeling for the analyzed water system. Exhibit B at the back of Appendix E provides the Node and Pipe Diagram for the computer model. The results in Appendix E show that the proposed water system for the Marja Acres project is adequate for fire protection. The results of the computer model show that a 3,000 gpm fire flow can be provided onsite with a minimum residual pressure of 23 psi and that 4,000 gpm fire flow can be provided with a minimum residual pressure of 40 psi. Available Fire Flow at 20 psi Residual. Fire flow available at a single point of the Marja Acres project was extrapolated to 20 psi residual. Table 4 shows the theoretical available fire flow at a proposed fire hydrant with that particular proposed hydrant flowing individually. Appendix E presents the computer model calculation results. TABLE 4 MARJA ACRES AVAILABLE FIRE FLOW AT A SINGLE POINT Node Fire Flow Capability, gpm Residual Pressure at Fire Hydrant, psi 52 3,250 20.1 The available fire flow at each fire hydrant is qualified as theoretical because the calculated flows cannot be extracted from a single fire hydrant. It is more accurate to describe the extrapolated flows at 20 psi residual to be indicative of what the water distribution system can deliver to a certain area. Jesse Kleist April 12, 2023 DEXTER WILSON ENGINEERING, INC. PAGE 13 Recycled Water System Computer Model and Analysis Computer modeling of the proposed onsite and existing offsite recycled water system for the Marja Acres project was performed akin to the aforementioned water (potable) model to confirm the pipe sizes necessary to provide adequate recycled water service. The recycled water system was analyzed under its peak hour demand of 200 gpm. Appendix F provides the results of the computer modeling for the analyzed recycled water system. Exhibit C at the back of Appendix F provides the Node and Pipe Diagram for the computer model. The results in Appendix F show that the proposed recycled water system for the Marja Acres project is adequate for peak irrigation demand. The results of the computer model show that a 200 gpm peak flow can be provided onsite with a minimum residual pressure of 78 psi. Conclusion and Recommendations The following recommendations and conclusions are presented based upon the water system analysis performed for the Marja Acres project. 1. Water service to the project will be provided by the City of Carlsbad and the Carlsbad Municipal Water District’s public water system. 2. The Carlsbad Municipal Water District’s public water system does front the proposed project with an existing 241 Zone 12-inch water line in El Camino Real. 3. Elevations within the project range from approximately 60 to 89 feet resulting in a range of maximum static water pressures of approximately 65 to 78 psi. 4. Figure 2 presents the recommended onsite water system layout and required distribution pipe sizes. APPENDIX A CARLSBAD MUNICIPAL WATER DISTRICT DESIGN CRITERIA Volume 2 2/16/2016 Page 15 of 58 3.2 PLANNING AND DESIGN CRITERIA 3.2.1 Water Flow Generation The following domestic water supply demands are used in the development of the water system. A. Residential Average daily flow 550 GPD/Single Family per dwelling unit 250 GPD/Multi-Family per dwelling unit B. Non-Residential Average daily flow 2,300 GPD/10,000 Sq. Ft. C. Fire Flow As a general guide, the following design criteria shall be used for determining fire flow requirements. The Fire Marshal will normally determine the specific fire flow criteria for a project. 1. Residential dwelling units shall use a minimum of 1,500 gpm from any two hydrants at a minimum of 20 psi of residual pressure at the main for 2 hours duration. 2. Multi-family residential units shall use a minimum of 3,000 gpm from any two hydrants at a minimum of 20 psi of residual pressure at the main for 2 hours duration. 3. Schools, commercial and industrial areas shall use a minimum of 4,000 gpm for 4 hours duration out of four hydrants at a minimum of 20 psi of residual pressure at the main. Higher requirements may be required if building floor area exceeds 300,000 square feet or is located near open space. 3.2.2 District Pipeline Sizing Criteria (Maximum Friction, Slopes, Velocities, Etc.) A. Water System Design Criteria 1. Approximately one pressure zone is required for each 100 feet change in elevation. 2. Minimum static pressure of 60 psi. 3. Maximum static pressure of 125 psi. Pressures up to 150 psi may be allowed with specific approval of the City Engineer. 4. Use existing pressure zones if they are compatible. 5. Static pressures are figured from the tank floor of existing or proposed tanks for determination of minimum static pressure. The static pressure at the tank overflow elevation shall be used for maximum static pressure. 6. A small amount of pressure zone overlap (where one can be served water with sufficient pressure from either zone) should be included at boundaries of each pressure zone. Volume 2 2/16/2016 Page 16 of 58 B. Hydraulic analysis of the System (Dynamic Pressures) shall address the following requirements: 1. Under peak hour demand and no fire flow, minimum pressure should be no less than 40 psi, should not exceed 3.5 feet/1,000 ft. head loss in the pipe, and velocity shall be below 8 ft/s. Maximum desirable head loss shall be 5.0 feet/1,000 ft. of pipe and maximum allowable head loss shall be no greater than 10 feet/1,000 feet of pipe at peak flow. The maximum allowable velocity shall be 10 ft/s. 2. Under maximum day demand plus fire flow, pressure in the system should not be less than 20 psi for the period of the fire incident (assume tank to be half full). During fire, pumps should be assumed to be off and the fire flow requirement is to be delivered 100% from storage tanks. 3. The maximum desired pressure drop between static pressures and dynamic pressures is 25 psi. 4. At least two sources of water from two different streets should be available for each development (i.e., looped). Two sources from the same transmission line are acceptable if source from a different street is unavailable. Dead-end water lines longer than 150-feet are not permitted, unless approved by the District. Looped systems are required as described above. 5. Dead-end water lines are to serve no more than 18 residences. A looped water line is required for 19 or more residences. Commercial / Industrial developments require looped water systems unless approved otherwise by the District and the Fire Marshal. 6. No more than one fire hydrant shall be allowed on a dead-end line. Water systems requiring 2 or more fire hydrants shall be looped. Minimum line size shall be 8-inches. 7. Approved double check detector assemblies (DCDAs) are required for all non- residential fire sprinkler systems per CSD W-22. This is particularly important for schools and commercial developments. 8. Dynamic pressures shall be analyzed with reservoir levels half full. 3.2.3 Water Master Plan Peaking Factors Average Day Demand (ADD) 1.0 Maximum Month Demand (MMD) 1.5 x ADD Maximum Day Demand (MDD) 1.65 x ADD Peak Hour Demand (PHD) 2.90 x ADD 6-4 | July 15, 2019 Figure 6-2: Recycled Water Peak Hour Pressure PROJECT AREA 1 Steven Henderson Subject:FW: Marja Acres - RW max demand From: Matteo Gaffo <mgaffo@gmplandarch.com> Sent: Monday, October 3, 2022 11:21 AM To: Mike Long <mlong@hwl-pe.com> Subject: Marja Acres - RW max demand Mike, Max demand for the recycled water would be 200 GPM MATTEO GAFFO PROJECT MANAGER 3176 Lionshead Ave. Suite 102 Carlsbad, California 92010 T 858 558 8977 gmplandarch.com APPENDIX B PRIVATE WATER REFERENCE AND WATER METER AND BACKFLOW PREVENTER SPECIFICATIONS 03/08/22 1ST PLAN CHECK GMEP GMEP AS NOTED 04/26/22 21-729 04/26/22 2ND PLAN CHECK P-1.1 03/08/22 1ST PLAN CHECK GMEP GMEP AS NOTED 04/26/22 21-729 04/26/22 2ND PLAN CHECK P-1.1 Marja Acres 629-030 4/12/2023 Carlsbad - Marja Acres Job Number Date Water Fixture Units The basis for the Water Fixture Units is "Private" per the 2022 California Plumbing Code.

The installation of the FEBCO air gap with the drain line terminating above a floor drain will handle any normal discharge or nuisance spitting through the relief valve. However, floor drain size may need to be designed to prevent water damage caused by a catastrophic failure condition. Do not reduce the size of the drain line from the air gap fitting.

DATE: November 12, 2021 SUBJECT: Marja Acres Residential Master Water Meters and Private Domestic Water System Sizing Background The Marja Acres project is located in the north-central portion of the City of Carlsbad. It is situated along El Camino Real to the southeast of Kelly Drive. The majority of the proposed 24 acre development will consist of 248 townhome residential units spread amongst several clusters where a master water meter is proposed for each cluster. The 17 different clusters vary from containing six units up to 34 units. The current site plan for the Marja Acres project is attached to the back of the memorandum. 2234 FARADAY AVENUE 0 CARLSBAD, CA 92008 • (760) 438-4422 • FAX (760) 438-0173 Jesse Kleist November 12, 2021 Page 2 Master Water Meter Sizing bvTownhome C.lusteE To size the master water meters an estimate of Water Fixture Units (WFUs) was done for each townhome residential cluster. This was achieved by calculating the typical number of WFUs for the townhome residential units. Using Chart A- 103.1(1) in the 2019 California Plumbing Code, a flow rate in gpm can be calculated from the WFUs. Using the City of Carlsbad's meter capacity ranges, a meter size and type can be determined from the flow rates in gpm. The WFU tabulation, Chart A-103.1(1) in the 2019 California Plumbing Code, and the City of Carlsbad meter flow rate range are all attached to this memorandum. The breakdown for each townhome cluster is summarized in Table 1 below.

The City primarily follows the AWWA standards for Cold Water Meters. As mentioned earlier, an e- mail correspondence stating this requirement from the City of Carlsbad is attached to this memorandum. The size for the master meters for the Marja Acres townhome clusters shall be either 1.5- inch positive displacement, 1.5-inch turbo, or 2-inch turbo depending on demand and unit quantities. Typical available pressures at the public water meter connections are expected to range between 60 psi and 70 psi. These 1.5-inch or 2-inch meter sizes are required based on a single meter supplying a respective townhome cluster. If a townhome cluster's private water system consists of a "looped" system with two meter connections then two smaller size meters could be utilized in lieu of the single larger meter. This two meter setup for a townhome cluster is not analyzed within this memorandum. Private Domestic Water System giziri Using the WFUs and flow rates for each townhome cluster as shown in Table 1, a worst case scenario was analyzed for the 2-inch meter and 1.5-inch meter clusters in regard to domestic demand onsite. The highest calculated domestic water demand for a 2-inch meter and 1.5- inch meter cluster respectively were inputted at the furthest distance from the public connection. This was done along the townhome cluster's main water distribution line and, to be conservative in the analysis, the entire flow was calculated across the entire piping length. Hydraulic calculations are attached to this memorandum confirming that a 6-inch diameter main cluster distribution water line can provide adequate service to the 2-inch meter clusters and 4-inch diameter main cluster distribution water line can provide adequate service to the 1.5-inch meter clusters. Residual pressure under maximum domestic demands is greater than 45 psi at the furthest unit's connection. Jesse Kleist November 12, 2021 Page 4 It is recommended to oversize the individual unit's supply laterals due to the low expected working pressures (45 to 50 psi) within the private water systems throughout the Marja Acres site.

Peak Hour Demand APPENDIX H COMMERCIAL WATER METER/SYSTEM SIZING REPORT Jesse Kleist April 4, 2025 Page 2 Water Meter Sizing – Commercial To size the master water meters a count of Water Fixture Units (WFUs) was done for the commercial area. This was achieved by utilizing the total number of WFUs for the entire commercial area per the project’s plumbing engineer. Using Chart A-103.1(1) in the 2022 California Plumbing Code, a flow rate in gpm can be calculated from the WFUs. Using the City of Carlsbad’s meter capacity ranges, a meter size can be determined from the flow rates in gpm. The WFU tabulation and Chart A-103.1(1) in the 2022 California Plumbing Code are attached to this memorandum as Attachment A. The City of Carlsbad meter flow rate ranges are attached as Attachment B to this memorandum. The breakdown for the commercial area is summarized in Table 1 below. TABLE 1 MARJA ACRES COMMERCIAL WFU, MAXIMUM FLOW, AND WATER METER SIZE Project Area WFUs1 Maximum Flow2 Water Meter Size3 Water Meter Capacity Bldg. Supply Size Commercial 164 82 gpm 1-inch (existing public meter) 62 gpm 4-Inch ¾-inch (proposed private sub- meter) 35 gpm Total 164 82 gpm -- 97 gpm -- 1 Attached WFU Breakdown (Attachment A) 2 From Chart A-103.1(1) in the 2022 California Plumbing Code (Attachment A) 3 Per City meter flow rate range (Attachment B) The sizes for the meters for the Marja Acres commercial area are recommended to be a combination of 1-inch (existing public meter) and ¾-inch (proposed private sub-meter). These two meters combined will provide a total capacity of 97 gpm which will be sufficient to accommodate the peak demand from the commercial area of 82 gpm. Typical available pressures at the water meter connections are expected to range between 60 psi and 70 psi. Jesse Kleist April 4, 2025 Page 3 The existing 1-inch public meter will supply the commercial area the vast majority of the time. The proposed ¾-inch private sub-meter will only supply the commercial area when demands exceed the 62 gpm capacity of the existing 1-inch public meter. A schematic layout of the domestic water system including all meters and sub-meters for Marja Acres is shown as Exhibit A2 at the back of this memorandum. Private Domestic Water System Sizing Using the WFUs and flow rates for the commercial area as shown in Table 1, a worst case scenario was analyzed in regard to peak domestic demand. Hydraulic calculations are attached to this memorandum as Attachment C confirming that the two meters and 4-inch distribution building supply can provide adequate service to the commercial area. Residual pressure under maximum domestic demands is greater than 52 psi at the furthest connection. More detailed hydraulic calculations for the entire project can be found in the overall final water study from April 2023. It is recommended to oversize the supply lateral (4-inch) due to the relatively low expected working pressures (50 to 55 psi psi) within the private water systems throughout the Marja Acres site.
