The project is bordered by the streets: Harrison Street, Chinquapin Avenue and Adams Street. This sewer analysis was prepared to determine the proposed flow from our project and to design the sewer lines to have a velocity of 2 feet per second or a slope of 2 percent. CITY OF OCEANSIDE CITY OF ViSTA CiTY OF SAN MARCOS mNITYUAP E. Flowrate Generation 1) An Equivalent Dwelling Unit (EDU) = 220 gai/day. Average Daiiy Flow (ADF) 2) A peaking factor (PF) of 2.5 multiplied times the ADF shall be used to determine Peak Daily Flows (PDF). PDF = ADF x 2.5 a) Residential: Single Family Residence = 1 EDU b) Commercial Property: 1 EDU/1,800 (building space) i) To convert raw land to square feet of buiiding space, assume 30% coverage. This could vary significantiy dependent development constraints. ii) To convert improved pads to square feet of buiiding space, assume 40% of coverage. 3) Industriai Property: 1 EDU/5,000 ft^ (warehouse space) 1 EDU/1,800 ft^ (office space) a) To convert raw land to square feet of building space, assume 30% coverage. This could vary significantly dependent issues such as environmental restrictions. b) To convert improved pads to square feet of building space, assume 40% of coverage. c) Assume 60% of buiiding space is warehouse, and 40% is office space. HORIZONTAL AND VERTICAL l-AYOUT A. Streets: See City of Carisbad Standard Drawing No. GS6 for location. B. Alley: Main to centeriine shali be a minimum of three feet (3') offset. Private Street: Shali require special design and conditions. Easement shall be 20 feet. Horizontai Cun/e: SDR 35, PVC pipe may be cun/ed horizontally with the following limitation: p pl IM'HM ^l dm 6-ihch 150 feet 8-inch 200 feet 10-inch 250 feet 12-inch 300 feet 15-inch 375 feet 18-inch 450 feet City Engineer shall approve curvatures for larger diameter pipe.
