Two 8" lateral Polyvinyl chloride (PVC) connections will service the onsite fire system, originating from an existing 12" water line running below Lionshead Ave. The fire line connection will utilize two 8" double detector check valves (DDCV). The connection services an onsite fire system consisting of 8" and 6" lines that will serve the fire sprinklers and five separate hydrants around the site. CRITERIA AND METHODOLOGY The modeling of the onsite fire service lines was completed using the EPANET 2.0 program (EPANET). Usage of the water and sewer plans provided the scaled distances for the project. The schematic used in EPANET can be found on Attachment 1. Head Loss Across Fittings I Minor losses encountered in the Ductile Iron Pipe (DIP) fittings along the pipelines were neglected in the model (i.e. elbows, tees, etc.). The headloss (HL) across the backflow apparatus I was addressed and modeled using the method described below. The Watts 8" double check detector assembly (DCDA) was modeled as a general purpose valve (GPV) in series with a check valve. The HL curve can be found on the specification sheet for the I Watts DCDA on Attachment 2. This information was used to develop Figure 1 below, which displays the HL curve created for usage in EPANET to model the flow within the system. Additional information for the proposed backflow device can be found on Attachment 2.

Modeled Demand Flows To ensure the onsite hydraulics can supply adequate flow to the system during a fire evert, Excel Engineering tested a primary scenario. The 2013 California Fire Code (CFC) refers to Appendix B to obtain fire-flow requirements for buildings. Using Table B105.1, the 99,720 square foot building determines that it requires a fire-flow of 6,750 gallons per minute (gpm). By providing the building with fire sprinklers, the required flow can be reduced by 75 percent and results in a required flow of 1,688 gpm. For the purposes of this report, the flow was only reduced by 50 percent to 3,375 gpm. The calculated fire-flow system criteria enabled the following scenarios to be tested: Scenario 1 - For this scenario, a demand of 3,375 gpm was supplied to the system and distributed between the two hydrants furthest from the onsite connection, and no flow was provided to the building. Scenario 2— For this scenario, a demand of 3,375 gpm was supplied to the system and distributed between the two hydrants furthest from the onsite connection, and a flow of 500 gpm was provided to the building. Tie-In Pressures Available Existing flow and pressure data from the public system in Lionshead Ave was taken from a flow analysis performed by the City of Carlsbad Fire Department (CCFD) on 06/30/2016. To model I this scenario in EPANET the pressure available was modeled as a reservoir with a total head equivalent to the Static Pressures given in the analysis provided by the City. This pressure test 1 data can be found on Attachment 3 to this report, and is summarized in the table below.

Minimum residual pressure for the project shall be 20 pounds per square inch (psi) during fire flow demand. 2. Pipe velocities shall not exceed 10 feet per second (fps). I The velocity and pressure requirements for this project scenario are discussed below. I . Scenario 1 For this scenario, the highest velocity found in the system was in multiple pipes. This velocity was recorded as 10.83 fps. See Attachment 4. I o Minimum Pressure - For this scenario, the minimum pressure in the system is found in Junction 5. The recorded pressure was 77.33 psi. See Attachment 5. I A velocity of 19.15 fps was found in the pipes leading to the hydrants (Pipe 11 and 12) for this scenario. I . Scenario 2 For this scenario, the highest velocity found in the system was in multiple pipes. This velocity was recorded as 12.81 fps. See Attachment 6. I o Minimum Pressure - For this scenario, the minimum pressure in the system is found in Junction 5. The recorded pressure was 73.27 psi. See Attachment 7. I A velocity of 19.15 fps was found in the pipes leading to the hydrants (Pipe 11 and 12) for this scenario.
