I Grand Pacific Development PROJECT NAME: Lot 9 Development, Westin Hotel & Timeshare PROJECT ADDRESS: The Crossings Drive PROJECT DESCRIPTION: UNDERGROUND FIRE LINE PLANS and FIRE FLOW ANALYSIS FIRE FLOW ANALYSIS FOR: LOT 9 Development Westin Hotel and Timeshare Prepared For: Grand Pacific Development, Inc. Prepared By: ENGINEERING LAND PLANNING ENGINEERING SURVEYING 440 STATE PLACE, ESCONDIDO, CA 92029 PH (760)745-8118 FX (760)7451890 Excel Reference No.: 13-070 Date: January 13, 2017 PURPOSE/PROJECT DESCRIPTION This water system analysis was conducted to check the capacities of the proposed on site private underground fire distribution system that will serve the proposed Lot 9 Development Westin Hotel and Timeshare. A 12" lateral Polyvinyl chloride (PVC) connection will service the onsite fire system, originating from an existing 16" water line running below The Crossings Drive. The fire line connection will utilize a 12" double detector check valve (DDCV). The connection services an onsite fire system consisting of a 12" line that will serve the fire sprinkler systems for a proposed hotel and a timeshare building, along with three 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). The node and link numbers associated with the hydraulic analysis using EPANET are shown on Attachment S. HEAD LOSS ACROSS FITTINGS Minor loses encountered in the ductile iron pipe (DIP) fittings along the pipelines were neglected in the model (i.e. elbows, tees, etc.). The head loss (HL) across the backflow apparatus was addressed and modeled using the method described below. The Ames 12" double check detector assembly (DCDA) was modeled as a general purpose valve (GPV). The HL curve can be found on the specification sheet for the DCDA on Attachment 1. This information was used to develop Figure 1, 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 1.

MODELED DEMAND FLOWS To ensure the onsite hydraulics can supply adequate flow to the system during a fire event, Excel Engineering tested the main scenario. With the fire flow system criteria provided by the Fire Marshall, the following test scenario was conducted: Scenario 1— For this scenario, a demand of 1,500 gallons per minute was supplied to both buildings. TIE-IN PRESSURES AVAILABLE Existing flow and pressure data from the public system in The Crossings Drive was taken from a flow analysis performed by the City of Carlsbad on 10/03/2016. To model this available pressure in EPANET the pressure available was modeled as a reservoir in series with a pump, with a total head equivalent to the Static Pressures given in the analysis provided by the City. This pressure test data can be found on Attachment 2 to this report, and is summarized in Table 1. 2 Table 1: CCFD Flow Test Results Static I Total Head I I Hydrant No. I Static Pressure Elevation (ft.) I I Available I Reservoir I I I I Pressure (psi) I Number (ft. of head) I (ft.) I H60365 62 143 232 375 I 1 I CALCULATONS AND CONCLUSIONS This performed analysis confirms that the underground fire distribution system will be adequate to provide fire flows to the site for Scenario 1 in accordance with the following requirements: Minimum residual pressure for the project shall be 20 pounds per square inch (psi) during fire flow demand. Pipe velocities shall not exceed 10 feet per second (fps). The velocity and pressure requirements were met for this project. Scenario 1 For this scenario, the highest velocity found in the system was in Pipe 15. This velocity was recorded as 9.57 fps. See Attachment 3. Minimum Pressure -For this scenario, the minimum pressure in the system is found in Junction S. The recorded pressure was 46.64 psi. See Attachment 4. Attachment 1 ES-A-3000SS Series 3000SS AL AMES Double Check Detector Assemblies Sizes: 21/211 - 12 (65 - 300mm) Job Name - Job Location Engineer - Approval - Series 3000SS Double Check Detector Assemblies are designed for use in accordance with water utility non-health hazard containment requirements. It is mandatory to prevent the reversef lowoffireprotection system substances, i.e.,glycerinwetting agents, stagnantwater and water of non-potable quality from being pumped or siphoned into the potable water supply. Specifications A Double Check Detector Assembly shall be installed on fire protection systems when connected to a drinking water supply. Degree of hazard present is determined by the local authority having jurisdiction. The main valve body shall be manufactured from 300 Series stainless steel to provide corrosion resistance, 100% lead free* through the waterway. The double check detector assembly consists of two independently operat- ing, spring loaded check valves, two UL, FM, OSY resilient seated gate valves, and bypass assembly. The bypass assembly consists of a meter (cubic ft. or gallons), a double check including shutoff valves and required test cocks. Each cam-check shall be internally loaded and provide a positive drip tight closure against reverse flow. Cam-check includes a stainless steel cam arm and spring, rubber faced disc and a replaceable seat. There shall be no brass or bronze parts used within the cam-check valve assembly. The check valve seats shall be of molded thermoplastic construction. The use of seat screws as a retention method is prohibited. All internal parts shall be accessible through a single cover on the valve assembly. The valve cover shall be held in place through the use of a single grooved style two-bolt coupling. The bypass line shall be hydraulically sized to accurately measure low flow. The bypass line shall con- sist of a meter, a small diameter double check assembly with test cocks and isolation valves. The bypass line double check valve shall have two independently operating modular poppet check valves, and top mounted test cocks. The assembly shall be an Ames 3000SS. Materials All internal metal parts: 300 Series stainless steel, Main valve body: 300 Series stainless steel, Check assembly: Norylm Flange dimension in accordance with AWWA Class D.
