Sewer System Hydraulic Analysis Date: May 11, 2021 For:City of Bakersfield By: John R. Gass, P.E. Public Works Project Manager Bakersfield, CA Hunsaker & Associates Irvine, Inc. Project:Tentative Tract 7337 – Phase 2, 5 & 10 Hunsaker & Associates Irvine, Inc. (H&A) is pleased to submit the Sewer System Hydraulic Analysis for Phase 2, 5 & 10 of Tentative Tract 7337, previously identified as Tract 6498-Phase 2. This analysis has been prepared to analyze the proposed changes to the previously approved sewer system for the aforementioned residential development project in the City of Bakersfield. The project lies within the jurisdiction of the City of Bakersfield and their standards have been used for this report. Hydraulic models were prepared using Bentley Systems modeling software to model the peak flows the proposed sewer systems would experience. This evaluation is based on existing and known conditions and should be re-evaluated if these conditions change or new information becomes available. Any interpretation of the information presented in this report should be referred to H&A to ensure the integrity of the results. Project Location The project is located adjacent to City Hills Drive, Panorama Drive & Masterson Drive in the City of Bakersfield. The general project location is shown on exhibit entitled, “Sewer System – Figure 1.” Summary of Findings 1.The proposed project, Tentative Tract 7337-Phase 2, will include 12 residential dwelling units located on Asuncion Place. The sewer system was originally designed as an 8-inch line with a slope at 0.35 percent to the existing 8-inch sewer line in Moengo Way. The sewer line is proposed to lower the connection point at Moengo, to allow for the last reach to be constructed as a 6-inch with a slope of 1 percent. 2.The proposed project, Tentative Tract 7337-Phase 5, will include 25 residential dwelling units located at the northwest portion of the project. The sewer system was originally designed to drain to Kuma Way, via Cuzco Way & Potosi Way. Currently the construction of the downstream portions of Cuzco Way & Potosi Way will be constructed at a later date. It is proposed to re-route the sewer system, for the 25 lots, to the existing 8-inch sewer line in Moengo Way. 3.The proposed project, Tentative Tract 7337-Phase 10, will include 29 residential dwelling units located on Pasto Way. The sewer system was originally designed as an 8-inch line with a slope at 0.35 percent to the existing 8-inch sewer line in Pilar Way. The sewer line is proposed to construct the last reach as a 6-inch line at 1 percent. Sewer System Hydraulic Analysis, cont. May 11, 2021 Page 2 4.The sewer system schematic is shown on the attached exhibit entitled, “Sewer System – Figure1.” The exhibits identifies points of sewer connection, sewer reaches, manholes, proposed and existing sewer mains. 5.The existing onsite sewer collection system analyzed consists of 8-inch diameter mains in Moengo Way, Kuma Way, Limache Place and Pilar Way, constructed at slopes of 0.35 percent. The proposed re-routed sewer in Cuzco Way Patagonia Way is designed at 0.4 percent slope due to the site grading and the elevation of the connection point at Moengo. 6.In order to analyze the impact for re-routing the sewer, we have estimated the average daily discharge of the domestic sewage using 250-gallons per day per unit, as identified in the City of Bakersfield Public Works Department Subdivision & Engineering Design Manual (Design Manual). Using the sum of the average daily flows for each reach in the study area, we peaked the flows per the Design Manual, to calculate the estimated capacity and velocities. We prepared a hydraulic model using Bentley FlowMaster V8i. The summary of outputs from the model runs is included in the Appendix of this report. 7.The calculation demonstrate the proposed and existing 8-inch sewer lines have adequate capacity, however, there are only 3 reaches that meet the velocity requirement of 2 fps. The vast majority has a velocity 1.50 fps to 2.16 fps. The sewer line with velocities below 1.5 fps, have calculated velocities ranging from 0.91 fps to 1.19 fps. This is due to the limited number of connected homes, existing slopes of 0.35 percent and the proposed slopes of 0.4 percent. We sincerely trust these calculations will provide sufficient evidence that the proposed sewer system is adequate, even with the velocities less than the desired 2 fps.
