WATER ● WASTEWATER ● RECYCLED WATER CONSULTING ENGINEERS 2234 FARADAY AVENUE ● CARLSBAD, CA ● (760) 438-4422 WATER STUDY FOR THE CARLSBAD VILLAGE MIXED USE PROJECT IN THE CITY OF CARLSBAD November 3, 2023 Andrew Cerrina November 3, 2023 Carlsbad Village Mixed Use Water Study DEXTER WILSON ENGINEERING, INC. PAGE 3 Purpose of Study The purpose of this study is to provide a fire flow analysis to verify that the required fire hydrant flow can be delivered to the Carlsbad Village Mixed Use site utilizing the existing public water system and that the project can be adequately served from existing infrastructure. This report will provide recommendations for any immediate improvements to the existing public water system determined to be necessary for the public water system to deliver the required fire hydrant flow and pressure. Water System Design Criteria The design criteria used to analyze the public water system in the vicinity of the Carlsbad Village Mixed Use project are consistent with Volume 2 of the 2022 City of Carlsbad Engineering Standards: Potable and Recycled Water Standards (2022 Volume 2 Engineering Standards). Appendix A includes excerpts from the 2022 Volume 2 Engineering Standards pertinent to this report for reference. The criteria include a minimum static pressure of 60 psi, a desired maximum static pressure of 125 psi, and a maximum static pressure allowed of 150 psi. Under Peak Hour Demand conditions, minimum residual pressure at any location must not be less than 40 psi. Under a Maximum Day Demand with Fire Flow, a minimum residual pressure of 20 psi must be maintained in the water system. Peaking factors used in analyzing demand scenarios were 1.6 for average day to maximum day demands, and 2.9 for average day to peak hour demands. Projected Water Demand The expected water demand for the Carlsbad Village Mixed Use project was estimated using water demand criteria from the 2022 Volume 2 Engineering Standards. Table 1 presents the estimated onsite water demand for the project. Andrew Cerrina November 3, 2023 Carlsbad Village Mixed Use Water Study DEXTER WILSON ENGINEERING, INC.

Table 4-2 Design Criteria from CMWD Potable Water Master Plan, June 17, 2019. Per Table 1, average day demand for the Carlsbad Village Mixed Use project is 40,810 gpd or 28.3 gpm. The maximum day demand is 65,296 gpd or 45.3 gpm (ADD x 1.6). The peak hour demand is 118,349 gpd or 82.2 gpm (ADD x 2.9). Fire Flow Requirements The fire flow requirement for the Carlsbad Village Mixed Use project was determined using the 2022 California Fire Code and the 2022 Volume 2 Engineering Standards. 2022 California Fire Code. The required fire hydrant flow for the project was determined using the 2022 California Fire Code and is based on building square footage and type of construction. The project’s building square footages, types of construction, and fire hydrant flow requirement based on the 2022 California Fire Code are summarized in Table 2. Appendix B includes excerpts from the 2022 California Fire Code for reference. Andrew Cerrina November 3, 2023 Carlsbad Village Mixed Use Water Study DEXTER WILSON ENGINEERING, INC.

A 50% reduction factor is applied per Table B105.1(2) and Table B105.2 of the 2022 California Fire Code. The City of Carlsbad allows a 50% maximum reduction. 2. Reduced fire flow requirement shall not be less than 1,500 gpm per Table B105.2 in the 2022 California Fire Code. 3. Building area shows area of largest floor per Section B104.3 of the 2022 California Fire Code. Per Table 2, the fire flow requirement for the Carlsbad Village Mixed Use project is 2,500 gpm. The existing public water system was analyzed using a 2,500 gpm fire flow requirement for the project. Existing Water System The Carlsbad Village Mixed Use project is within the City of Carlsbad 255 Pressure Zone. There is an existing 8-inch 255 Pressure Zone public water line south of the project in Oak Avenue. North of the project in Carlsbad Village Drive there is an existing 6-inch 255 Pressure Zone public water line east of Harding Street that increases to an 8-inch water line east of the fire hydrant near the northeast corner of the project site. Figure 2 presents the existing public water system in the vicinity of the project. Finish Floor elevations within the Carlsbad Village Mixed Use project site range between 66 feet and 70 feet. With service from the 255 Pressure Zone, this results in a maximum static pressure range of 80 psi and 81 psi within the development. When static pressures exceed 80 psi, the California Plumbing Code requires pressure regulating valves at each building supply. Andrew Cerrina November 3, 2023 Carlsbad Village Mixed Use Water Study DEXTER WILSON ENGINEERING, INC. PAGE 7 Proposed Water System The Carlsbad Village Mixed Use project will connect to the 255 Pressure Zone water lines in Carlsbad Village Drive and Oak Avenue. The Carlsbad Municipal Water District has indicated that the existing 6-inch water line in Carlsbad Village Drive, from Harding Street to the existing fire hydrant near the northeast corner of the project site, will need two be upgraded to an 8-inch water line to meet the District’s minimum pipeline diameter criterion. Because the upgrade is not necessary from a capacity standpoint, the Carlsbad Municipal Water District has indicated that they will enter into a cost-sharing agreement with the project to upgrade the water line in question. Figure 2 presents the proposed water system for the Carlsbad Village Mixed Use project. As shown in Figure 2, the Carlsbad Village Mixed Use project will make two connections to the proposed 8-inch water line in Carlsbad Village Drive to provide domestic water service to the retail portion of the project and to provide water service for the onsite private fire protection system. The domestic water service in Carlsbad Village Drive will include a master meter that will serve two retail buildings. The private fire protection system will supply water to the private fire sprinklers systems proposed for the buildings within the project; there are no private fire hydrants proposed onsite. The project will also connect to the existing 8-inch water line in Oak Avenue to provide domestic water service to the residential portion of the project. The domestic water service in Oak Avenue will include a master meter that will serve two residential buildings. In accordance with City of Carlsbad Standards, each domestic water meter will be followed by a reduced pressure principle backflow preventer, and the fire service lateral will include a double check detector assembly backflow preventer. A preliminary analysis for the sizing of the domestic water service laterals and meters is included in this study. The final design of the public improvements including domestic laterals, irrigation laterals, and fire services will be a part of the public improvement plan preparation phase for this project. Andrew Cerrina November 3, 2023 Carlsbad Village Mixed Use Water Study DEXTER WILSON ENGINEERING, INC. PAGE 8 Domestic Water Meter Sizing Two master water meters are proposed to provide domestic water service to the project: one water meter will provide water service to the retail portion of the project and the other water meter will provide water service to the residential portion of the project. The meter sizing was determined based on the total number of Water Fixture Units that will be served by the meter. Irrigation internal to the project is proposed to be connected separately and, therefore, only domestic demands are being met by the domestic water meter. For the retail master water meter, the meter is expected to be a 2-inch meter but there is not enough information available to provide a meter size at this point. For the residential master water meter, the total number of Water Fixture Units was determined using the preliminary architectural plans for the residential buildings. A breakdown of Water Fixture Units for the proposed building by floor plan is provided in Appendix C. The total Water Fixture count for the residential buildings proposed for the Carlsbad Village Mixed Use project is 4,790.5. Using an extrapolation of Chart A 103.1(1) from the California Plumbing Code, this converts to a maximum expected demand of 580 gpm. The Carlsbad Municipal Water District uses Badger E-Series G2 Ultrasonic Meters (see Appendix D for meter cutsheet). Because a 4-inch Badger E-Series G2 Ultrasonic Meter has an allowable capacity of 1,100 gpm, the maximum expected demand for the project is proposed to be satisfied by use of a single 4-inch meter. The final meter sizes for the retail master meter and the residential master meter will need to be confirmed during final engineering. Public Water System Analysis The public water system in the vicinity of the Carlsbad Village Mixed Use project was analyzed using a computer model. The University of Kentucky KYPIPE program was used to model the existing and proposed water system for the Carlsbad Village Mixed Use 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. Andrew Cerrina November 3, 2023 Carlsbad Village Mixed Use Water Study DEXTER WILSON ENGINEERING, INC. PAGE 9 Available Hydraulic Grade Line. The available hydraulic grade line (HGL) was determined using fire hydrant flow test data for a fire hydrant located on the south side of Carlsbad Village Drive fronting the project. The fire hydrant flow test is provided in Appendix E. The tested fire hydrant was used as the water source in the computer model. Using the data provided in the hydrant flow test, an extrapolation calculation was used to determine the available pressure and HGL at average day demand, maximum day demand, peak hour demand, and maximum day plus fire flow scenarios for the project. The extrapolation calculation is provided at the end of Appendix E. The results pertinent to the analysis are highlighted in the extrapolation calculation for reference. Computer Model Results Computer modeling of the existing and proposed offsite public water system in the vicinity of the Carlsbad Village Mixed Use project was analyzed under average day, peak hour, and maximum day plus 2,500 gpm fire flow demand scenarios. For the maximum day plus 2,500 gpm fire flow demand scenario, the 2,500 gpm fire flow requirement was split among two fire hydrants in the computer model run. Appendix F provides the results of the computer modeling for the existing public water system and Appendix G provides the results of the computer modeling for the proposed public water system. Exhibit A at the back of this report provides the Node and Pipe Diagram for the computer model. Andrew Cerrina November 3, 2023 Carlsbad Village Mixed Use Water Study DEXTER WILSON ENGINEERING, INC. PAGE 10 Analysis of Computer Model Results – Existing Public Water System. The results in Appendix F show that the existing public water system presented in Figure 2 (no upgrade to 6-inch line in Carlsbad Village Drive) is able to provide adequate flow and pressure to the Carlsbad Village Mixed Use project for domestic and fire protection service. Under peak hour demand, the minimum pressure fronting the site in Carlsbad Village Drive is 70 psi. Under the maximum day plus fire flow demand scenario, the results show that a 2,500 gpm fire flow can be provided with a minimum residual pressure of 27 psi in the public water system in the vicinity of the project. The maximum velocity in the public water system under the maximum day plus fire flow scenario is 20.2 fps which is less than the allowable 15 fps for maximum day plus fire flow scenarios. Analysis of Computer Model Results – Proposed Public Water System. The results in Appendix G show that the proposed public water system presented in Figure 2 (with upgrade to 6-inch line in Carlsbad Village Drive) is able to provide adequate flow and pressure to the Carlsbad Village Mixed Use project for domestic and fire protection service. Under peak hour demand, the minimum pressure fronting the site in Carlsbad Village Drive is 70 psi. Under the maximum day plus fire flow demand scenario, the results show that a 2,500 gpm fire flow can be provided with a minimum residual pressure of 28 psi in the public water system in the vicinity of the project. The maximum velocity in the public water system under the maximum day plus fire flow scenario is 12.0 fps which is less than the allowable 15 fps for maximum day plus fire flow scenarios. The results of the analyses show that there are no capacity-related improvements needed, as the existing water system can provide adequate service to the Carlsbad Village Mixed Use project. Andrew Cerrina November 3, 2023 Carlsbad Village Mixed Use Water Study DEXTER WILSON ENGINEERING, INC. PAGE 11 Conclusions and Recommendations The following recommendations and conclusions are made based on an analysis of the potable water system analysis for the Carlsbad Village Mixed Use project. 1. The Carlsbad Village Mixed Use project will be served by the City of Carlsbad 255 Pressure Zone. 2. Finish grade elevations within the existing site range from 66 feet to 70 feet. This results in a maximum static pressure range of 80 psi to 81 psi with service from the City of Carlsbad 255 Pressure Zone. 3. Individual pressure regulators must be installed at each building where static pressure exceeds 80 psi in order to maintain building service pressures below 80 psi in accordance with the California Plumbing Code. 4. Water service is proposed to include three connections to the existing public water system: two connections will be made for domestic water service and one connection will be made for fire protection service. 5. The Carlsbad Municipal Water District has indicated that the existing 6-inch water line in Carlsbad Village Drive, from Harding Street to the existing fire hydrant near the northeast corner of the project site, will need two be upgraded to an 8-inch water line to meet the District’s minimum pipeline diameter criterion. Because the upgrade is not necessary from a capacity standpoint, the Carlsbad Municipal Water District has indicated that they will enter into a cost-sharing agreement with the project to upgrade the water line in question. 6. The existing and proposed public water system can provide a maximum day plus 2,500 gpm fire flow demand for the project with a minimum residual pressure greater than 20 psi. The proposed public water system is presented in Figure 2. 7. All new water service laterals to be installed shall conform to the requirements of the Carlsbad Municipal Water District.

Electronic metering provides information—such as rate of flow and status and alarm indication—and data not typically available through traditional, mechanical meters and registers. Electronic metering minimizes measurement errors due to sand, suspended particles and pressure fluctuations. Ultrasonic 3, 4, 6 and 8 inch Meter Features • Open flow tube design prevents flow obstruction to reduce pressure loss • Greater turn-down ratio for extended flow ranges and increased revenue • Easy-to-read, 9-digit LCD display, which presents consumption, rate of flow, unit of measure, pressure, temperature, alarm conditions and firmware version • Pressure alarm and pressure and temperature data reported through ORION Cellular LTE-M/LTE endpoints and BEACON® • Field programmable registration and maintains an hourly internal logging capacity of 160 days of data • Single and dual outputs include high resolution industry standard ASCII encoder protocol, scaled/unscaled and 4-20 mA The meter is available with an inline connector for easy connection and installation to ORION endpoints. It is also available with a flying lead for field splice connection. APPLICATIONS Use the E-Series Ultrasonic meter for measuring potable cold water in commercial and industrial services. The meter is also ideal for non-potable, reclaimed irrigation water applications or less than optimum water conditions where small particles exist. E-Series Ultrasonic meters meet and exceed AWWA C715 and the most recent revision of AWWA C750 Standards. The lead-free bronze alloy meters comply with the lead-free provisions of the Safe Drinking Water Act and NSF/ANSI/CAN Standards 61 and 372. E-Series Ultrasonic meters also conform to UL 327B and FM 1044 for fire service applications. OPERATION & PERFORMANCE As water flows into the measuring tube, ultrasonic signals are sent consecutively in forward and reverse directions of flow. Velocity is then determined by measuring the time difference between the measurement in the forward and reverse directions. Total volume is calculated from the measured flow velocity using water temperature and pipe diameter. The LCD shows total volume, unit of measure, rate of flow, pressure, temperature, firmware and alarm conditions (reverse-flow, no usage, empty pipe, exceeding max flow, suspected leak, pressure, temperature, end of life and measurement error). In normal temperature range of 45…122° F (7…50° C), the Ultrasonic “new meter“ consumption measurement is accurate to: • ±1.5% over the normal flow range • ±3.0% from the extended low flow range to the minimum flow value CONSTRUCTION The E-Series Ultrasonic meter features lead-free bronze alloy meter housing, ultrasonic transducers, a meter-control circuit board with associated wiring, LCD and battery. Wetted elements are limited to the pressure vessel and transducers. The electronic components are housed and fully potted within a molded, engineered polymer enclosure, which is attached to the meter housing. The transducers extend through the housing and are sealed by O-rings, enabling turbulence-free water flow through the tube. The open flow tube design prevents obstruction of flow to reduce pressure loss and provide long-term accuracy. METER INSTALLATION For long-term performance the meter is weatherproof, UV-resistant, fully submersible and can be installed using horizontal or vertical piping. The registration electronics and battery are encapsulated to withstand harsh environments and protect the electronics in flooded or submerged pit applications. The meter will not measure flow when an “empty pipe“ condition is experienced. An empty pipe is defined as a condition that occurs when the flow sensors are not fully submerged.
