November 30,2015 Alliance Land Planning & Engineering, Inc. 2248 Faraday Avenue Carlsbad, CA 92008 Attention: Craig Whitteker, P.E., President DEXTER S . WILSON, P.E. ANDREW M. OVEN, P.E. STEPHEN M. NIELSEN, P.E. NATALIE J . FRASCHETTI, P .E. 528-033 Subject: Robertson Ranch PA-7 and PA-8 Apartments Project in the City of Carlsbad Introduction This report will address three aspects of the water supply system for the Robertson Ranch PA-7 and PA-8 Apartments development project. These are: 1. Sizing of the domestic water service lateral, meter, backflow preventer, and building supply piping to provide domestic service to the Apartments project. 2. Sizing of the fire protection system service laterals, detector check backflow preventers, and onsite private fire protection water system to ensure that the onsite private fire hydrants can deliver the necessary fire hydrant flow at greater than 20 psi residual pressure within the Apartments project. 3. Sizing of the fire sprinkler service laterals serving the Apartments project which laterals will be connected to the private onsite fire protection system piping outlined in Item 2 above. 2234 FARADAY AVENUE • CARLSBAD, CA 92008 • (760) 438-4422 • FAX (760) 438-0173 Craig Whittaker, P.E. November 30, 2015 The domestic and fire protection system laterals for the Robertson Ranch PA-7 and PA-8 Apartments project will be connected to the proposed 12" 349 Pressure Zone public water system piping in West Ranch Street and Robertson Road fronting the project site on its east and south boundaries, respectively. Since the proposed public water system is presently under construction as part of the backbone infrastructure being installed for the Robertson Ranch development, a fire hydrant flow test cannot be performed. Thus, the available hydraulic grade line in the 12" 349 Pressure Zone piping in West Ranch Street was determined based on the water system analysis prepared for the master development titled, "Water System Analysis for Rancho Costera," April17, 2015, Dexter Wilson Engineering, Inc. Domestic Water System Sizing A single, separate domestic water service lateral is planned for the domestic service to each of the two apartment areas. The Apartment project in PA-7 will connect to the 12" 349 Zone public water main in Robertson Road. The Apartment project in PA-8 will connect to the 12" 349 Zone public water main in West Ranch Street. The water meter sizes needed to meet the demands of these two apartment project areas are based on the maximum expected domestic flowrate as determined from the California Plumbing Code. Appendix A presents the three building types which comprise the buildings within the PA-7 and PA-8 Apartment project. In Appendix A, each building type is marked with the total number of Water Fixture Units for that buil~ing and the associated peak water demand. Also included in Appendix A is a site plan for both Apartment projects identifying the types of buildings on the site. From this information, the total Water Fixture Units can be determined for PA-7 and PA-8 separately. The total Water Fixture Units for PA-7 Apartments project is 1,778.5 WFU. Using Chart A-2 from the Plumbing Code, this converts to a water demand of 300 gpm. The total Water Fixture Units for PA-8 Apartments project is 3,131.5 WFU. Using Chart A-2 from the Plumbing Code, this converts to a water demand of 445 gpm. DEXTER WILSON ENGINEERING, INC . PAGE 2 Craig Whitteker, P.E. November 30, 2015 Domestic Water Meter Sizing. The City of Carlsbad Utilities Department provided the flowrate ranges for their domestic water meters in an email dated August 12, 2015. A copy of this email is in Appendix A. It shows that a 3" meter allows a maximum flowrate of 400 gpm, and a 4" meter allows a maximum flowrate of 800 gpm. For the PA-7 Apartments project, with a water demand of 300 gpm, a 3" meter will be used. For the PA-8 Apartments project, with a water demand of 445 gpm, a 4" meter will be used. Domestic Water Service Backflow Preventer. The reduced pressure principle backflow preventer assembly after the City domestic water meter is recommended to be a 4- inch assembly in order to minimize the pressure loss through this device. A 4" backflow device is to be provided after the 3" meter for PA-7 and after the 4" meter for PA-8. Appendix A includes the manufacturer's literature for a Wilkins Model 375 backflow preventer. This unit or any equivalent unit is to be installed after each domestic meter for the PA-7 and PA-8 Apartment projects. Domestic Building Supply Piping. The domestic building supply piping is sized for a flow velocity of less than 8 fps. The domestic building supply piping for the PA-7 Apartments project is 4" diameter. At a maximum flowrate of 300 gpm, the flow velocity in a 4" line is 7. 7 fps. This velocity occurs only in a short section of piping after the backflow and prior to the 2.5" service lateral for Building 19 as shown in Exhibit A.2 at the back of this report. The domestic building supply piping for the PA-8 Apartments project is 6" diameter after the meter and backflow preventer. At a maximum flowrate of 445 gpm, the flow velocity in a 6" line is 5.1 fps. The 6" building supply line ties into a 4" looped line which provides service to all the buildings within the PA-8 site. The pipe sizing and layout of the private domestic water system for the PA-8 site is shown in Exhibit B.2 at the back of this report. Available Pressure at the Base of the Domestic Service Riser. The available pressure at the Base of the Risers for the domestic service to all the buildings within the PA-7 and PA-8 Apartment project sites is based on a hydraulic analysis of the service lateral, meter, backflow, and building supply piping for each Apartment site. DEXTER WILSON ENGINEERING, INC. PAGE 3 Craig Whitteker, P.E. November 30, 2015 The available hydraulic grade line in the public water main in West Ranch Street and Robertson Road was taken from the Peak Hour Demand computer modeling performed in the water system analysis prepared for the master development titled, "Water System Analysis for Rancho Costera," April 17, 2015, Dexter Wilson Engineering, Inc. The available hydraulic grade line under Peak Hour Demands is 348 feet. PA-7 Apartment Site. The PA-7 Apartment site domestic water supply configuration includes a 4" domestic service lateral, a 3" meter, a 4" reduced pressure principle backflow assembly, and a 4" building supply pipe. The system schematic for the domestic water system for PA-7 Apartments is Exhibit A.2 at the back of the report, and the calculations for pressure loss are included at the end of Appendix A. The results show the pressure at the Base of the Riser for each building by Building Number. The available domestic service pressure at the Base of the Risers for PA- 7 Apartments ranges from 63 psi to 76 psi. Under maximum static conditions, domestic service pressure will be between 98 to 100 psi based on a maximum available hydraulic grade line of 349 feet and building Finish Floor elevations ranging from 118.1 feet to 121.8 feet. Since this pressure is greater than 80 psi, a pressure regulator will need to be included in the building plans at the service entrance to each building to maintain internal building service pressures below 80 psi in accordance with the Plumbing Code. PA-8 Apartment Site. The PA-8 Apartment site domestic water supply configuration includes a 4" domestic service lateral, a 4" meter, a 4" reduced pressure principle backflow assembly, and a 6" building supply pipe leading to a 4" building supply loop. The system schematic for the domestic water system for PA-8 Apartments is Exhibit B.2 at the back of the report, and the calculations for pressure loss are included at the end of Appendix A. The results show the pressure at the Base of the Riser for each building by Building Number. The available domestic service pressure at the Base of the Risers for PA- 8 Apartments ranges from 48 psi to 59 psi. DEXTER WILSON ENGINEERING, INC. PAGE 4 Craig Whitteker, P.E. November 30, 2015 Under maximum static conditions, domestic service pressure will be between 92 to 94 psi based on a maximum available hydraulic grade line of 349 feet and building Finish Floor elevations ranging from 131.9 feet to 136.7 feet. Since this pressure is greater than 80 psi, a pressure regulator will need to be included in the building plans at the service entrance to each building to maintain internal building service pressures below 80 psi in accordance with the Plumbing Code. Private Fire Protection System Sizing A private fire protection system separate from the private domestic water system is being designed for the PA-7 and PA-8 Apartments project. The separate fire protection system is designed to carry the required fire flow plus the building fire sprinkler flow and maintain greater than 20 psi residual at the fire hydrants during a fire flow scenario. The computer model run from the April 17, 2015, master water study which was used to estimate the available hydraulic grade line was the Maximum Day Demand Plus 3,000 gpm Fire Flow Split Between Nodes 106 and 110. Node 110 is on the west side of the Senior Housing building at the intersection of Gage Drive and West Ranch Street. The residual hydraulic grade line at Node 110 for this computer model analysis was 327.7 feet. This hydraulic grade line is used in our calculations. The fire hydrant flow is based on the expectation that the required fire hydrant flow based on building square footage and type of construction will not exceed 3,000 gpm. The required fire sprinkler flow for the apartment buildings is 86 gpm. For the Recreation Building, the fire sprinkler flow is estimated as 186 gpm. An email from the fire sprinkler system designer is included in Appendix B and identifies these fire sprinkler flows for the Apartment site. The private fire protection system piping for each of the two Apartment sites includes: • Two 8" public fire service laterals for each site to create a looped fire protection system; • An 8" double check detector assembly at each fire service lateral; • 8" piping from the 8" backflow assembly through each Apartment site. DEXTER WILSON ENGINEERING, INC. PAGE 5 Craig Whitteker, P.E. November 30, 2015 Appendix B contains the computer model hydraulic calculations output for both PA-7 and PA-8 Apartment sites. The corresponding Node and Pipe Exhibits for each Apartment site are Exhibits A.l and B.l located at the back of this report. The residual pressures within the Apartment sites under a 3,000 gpm fire flow plus fire sprinkler flow ranged from 41psi to 69 psi. Fire Sprinkler Service Laterals to PA-7 and PA-8 Apartments The fire sprinkler designer recommended providing 4" fire sprinkler service laterals to each building within the PA-7 and PA08 Apartments project. This recommendation is included in the email presented at the beginning of Appendix B.

It was extremely helpful and accomplished a lot. Question: 1. What the allowable flowrates for the City's water meters beginning with 1" and going through 8" in size. However, I believe the City does not do or approve 8" size, so the largest would be 6 unless 8" is allowed. Any help getting that information would be much appreciated. Thank you again for your help and coordination.

The Compound Series meters comply with the lead-free provisions of the Safe Drinking Water Act, are certified to NSF/ANSI Standards 61 and 372 (Trade Designation: LL-NS) and carry the NSF-61 mark on the housing. All components of the lead-free bronze alloy meter (housing, measuring element, seals, and so on) comprise the certified system. Badger Meter Recorda II• Compound Series meters combine two metering technologies in one innovative package. A positive displacement chamber measures low flow, while a turbine chamber records high flow. Offered In four sizes. the Compound Series meter features: Patented design that eliminates the need for a trigger valve and maintains crossover accuracy. Permanently sealed, tamper-resistant register or encoder. Meters and encoders that are compatible with Badger Meter AMRIAMI systems and other approved reading technologies Badger Meter ORION• and GALAXY" AMRIAMI meter reading systems are available for all Compound Series meters. ltron• ERT reading systems are also available. An optional summator can be provided as an integral part of the register assembly. All register options are removable from the meter without disrupting water service. TAMPER-PROOF FEATURES Unauthorized removal of the register or encoder is inhibited by the use of an optional tamper detection seal wire screw, TORx• tamper-resistant seal screw or the proprietary tamper-resistant keyed seal screw. Each can be installed at the meter site or at the factory. APPLICATIONS Use the Recorda II Compound meter for measuring potable cold water in commercial and industrial applications where flow is in one direction only. The meter is an ideal choice for facilities that experience rapid and wide fluctuations in water demand, such as hospitals, universities, residential complexes and manufacturing or processing facilities. OPERATION At low flow rates, the Compound Series meter diverts water up through a bypass to the disc chamber. Leaving the chamber's outlet port, water flows beyond the turbine element and main valve. As the flow rate increases, a pressure differential is created that opens the main valve. The water then flows straight through the turbine chamber. In addition, a portion still flows through the disc chamber before exiting the meter. RCS-DS-Q0078-EN-04 (May 2015) Rotor and disc movements are transmitted by magnetic drive couplings to individual register odometers. The direct magnetic drive provides a positive, reliable and dependable register coupling for straight-reading or remote reading options. The self-lubricating thermoplastic register gearing is designed to minimize friction and provide long life. OPERATING PERFORMANCE The Recordall Compound Series meets or exceeds registration accuracy for low, normal operating, maximum continuous operation, and changeover flow rates as specified in AWWA Standard C702. CONSTRUCTION The Recorda II Compound Series meter's construction complies with ANSI and AWWA C702 standards. It consists of three basic components: meter housing, interchangeable measuring elements, and sealed direct reading registers. The measuring element consists of the disc measuring chamber, turbine head assembly, and high flow valve assembly. To simplify maintenance, the registers and measuring elements can be removed without removing the meter housing from the line. METER INSTALLATION The meter is designed for installations where flow is in one direction only. A separate strainer is required to ensure optimum flow conditioning and protection of the measuring element. Companion flanges for installation of meters on various pipe types and sizes are available in cast iron or NL bronze as an option. Product Data Sheet Recorda//• Compound Series Meter, Lead-Free Bronze Alloy, Sizes 2'; 3'; 4" & 6" REGISTERS I ENCODERS Standard-Sweep-Hand Registration The standard register is a straight-reading, permanently sealed magnetic drive register. Dirt, moisture, tampering and lens fogging problems are eliminated. The register has a six-odometer wheel totalization display, 360" test circle with center sweep hand, and flow finder to detect leaks. Register gearing is made of self-lubricating engineered polymer, which minimizes friction and provides long life. The multi- position register simplifies meter installation and reading. The register capacity is 100,000,000 gallons (1 0,000,000 ft', 1,000,000 m'). Optional-Encoders for AMRJAMI Reading Solutions AMR/AMI solutions are available for all Recordall Compound Series meters. All reading options can be removed from the meter without disrupting water service.
