RBF JN 55-100293 Ponto Vision EIR: JN 25-101951 Storm Water Mitigation Plan and Preliminary C'S-(z 4-"-? ECR CORPERATE CENTER WATER MODEL I DIN I F41 The project site is completely within a 550-pressure zone. Medical Building I, has an average day demand of 10 Gallons Per Minute (GPM)' Medical Building II, has an average day demand of 4 GPM' Day Care Center, has an average day demand of 2 GPM The maximum day peaking factor is 1.65 2 The peak hour peaking factor is 2.90 2 Fire hydrant demand is 3500 GPM for the 4 hydrants within 325 ft of Medical Building I. Fire hydrant demand is 2500 GPM for the 3 hydrants within 300 ft of Medical Building II. Fire hydrant demand is 2750 GPM for the 3 hydrants within 300 of the Day Care Center. ASSUMPTIONS All hydrant laterals will be 6" in diameter Water service to Medical Building I is 3" in diameter Water service to Medical Building II is 2" in diameter Water service to the Day Care Center is 1.5" in diameter A 3" Neptune TRU/FLO Compound water meter will be used for Medical Building I A 2" Neptune High Performance water meter will be used for Medical Building II A 1.5" Neptune High Performance water meter will be used for the Day Care Center 3" Reduced pressure backflow preventer will be used in Medical Center I 2.5" Reduced pressure backflow preventer will be used in Medical Center II and the Day Care Center. The elevation head from the 12" water main in the back of the site was 540 ft at the pipe to take into account losses in the system. The elevation head from the 24" water main on El Camino Real was 540 at the pipe to take into account losses in the system Flow to the fire service in the building is minimal and was neglected in the modeling. MODELS Model 1 was based on an 8" water main, 6" fire hydrant laterals, 3" water service to Medical Bldg I, 2" water service to Medical Bldg II, and a 1.5" water service to the Day Care Center. Demands are 10 GPM to Medical Bldg I, 4 GPM to medical Bldg II and 2 GPM to the Day Care Center. The maximum day peaking factor is used to adjust these demands for the maximum day scenario. The fire flow demand of 3500 'Building Demands were determined from the City of Carlsbad Design Standards 3.2.1. 2 Peaking Factors are given in the City of Carlsbad Design Standards 3.2.3. 3 Fire Hydrant demands were given by the Deputy Fire Marshal of the Carlsbad Fire Department. GPM total over the 4 fire hydrants nearest to Medical Bldg I was implemented for this model. Model 2 was based on an 8" water main, 6" fire hydrant laterals, 3" water service to Medical Bldg I, 2" water service to Medical Bldg II, and a 1.5" water service to the Day Care Center. Demands are 10 GPM to Medical Bldg I, 4 GPM to medical Bldg II and 2 GPM to the Day Care Center. The maximum day peaking factor is used to adjust these demands for the maximum day scenario. The fire flow demand of 2500 GPM total over the 3 fire hydrants nearest to Medical Bldg II was implemented for this model. Model 3 was based on an 8" water main, 6" fire hydrant laterals, 3" water service to Medical Bldg I, 2" water service to Medical Bldg II, and a 1.5" water service to the Day Care Center. Demands are 10 GPM to Medical Bldg I, 4 GPM to medical Bldg II and 2 GPM to the Day Care Center. The maximum day peaking factor is used to adjust these demands for the maximum day scenario. The fire flow demand of 2750 GPM total over the 3 fire hydrants nearest to the Day Care Center was implemented for this model. SUMMARY OF RESULTS All 3 models were conducted with H20Map Water software and were completed using the pipe alignment received on 6/21/2007. Each of the 3 models was completed using the specifications listed above. Table 1, below, summarizes the results of the modeling analysis. Detailed results for each of the models are included in the following pages.
