To provide a storm drainage system in accordance with the City of Bakersfield requirements and guidelines. 2. To provide an economical and reasonable design for storm drain conveyance and disposal facilities. 2.0 GUIDELINES The following design standards were used in the development of this study: 1. Initial times of concentration (roof to gutter) are 10 minutes for Commercial Development and 15 minutes for R-1 Development. 2. The following runoff coefficients were used for this project: • 0.42 - R-1, 6,000 S.F. • 0.55 - R-2, Multi-Family Housing • 0.90 - Commercial • 0.95 - Pavement, drives, and roofs 3. Rainfall intensity curves used are those shown on Plate D-1 of the City of Bakersfield, Subdivision & Engineering Manual. 4. Sub-areas using multiple run-off coefficients are given a weighted average based on the area relative to each coefficient. 5. Approximately 56% of the site is Soil Group C – Milham sandy loam with 0 to 2 percent slopes and the remaining 44% of the site classified as Soil Group A - Kimberlina fine sandy loam, 0 to 2 percent slopes. The soil groups were obtained from the US Department of Agriculture Soils Survey. A Soil Map is enclosed with this report. 3.0 DESIGN APPROACH Tract 6968 Phases 1 to 10, the future commercial corner, and the Future R-1/R-2 Development are all located within the City of Bakersfield, CA Section 5, T.29S., R.27E M.D.M. The drainage improvements identified with this project are designed to benefit all areas bounded to the east by Coffee Road, to the north by Etchart Road, to the south by Snow Road, and to the west by Tract 7264 that takes storm drain runoff to the Basin Drainage Area. All of the area within the aforementioned boundary have been included in this study and shall drain to the Drainage Basin identified in this study. The areas contributing to the projects retention basin are zoned Commercial, R-1 (Single Family), and R-2 (Limited Multi-Family) and have been modeled as such to accurately approximate the projects runoff. Although there is a future park site located within the project area, it has been determined the North of the River Recreation and Parks District (NOR) will retain all storm water runoff produced by the park onsite. The study area was divided into sub-areas used to identify all flow contributions to the proposed drainage inlets. Flows were estimated utilizing the City of Bakersfield Rational Method in accordance with the Subdivision Standards. Flows were computed using the formula Q=CIA, where “Q” is the flow in cubic feet per second, “C” is the runoff coefficient, “I” is the intensity in inches per hour and “A” is the area in acres. The 10-year Storm event was used to determine curb capacities, catch basin opening sizes, and pipe sizes. Tract No. 6968 DRAINAGE STUDY 4 The proposed project at ultimate buildout will consist of 374 residential lots ranging in size from 6,006 SF to 16,866 SF. The drainage system outlined in this study will collect the discharge produced by off-site areas such as Etchart Road, Coffee Road, Basalt Street and Snow Road. A weighted composite runoff coefficient was calculated for Drainage Areas 1, 2, 3, 17, and 18 to account for the different development types located within each subarea. Drainage Area 1 includes the south half of Etchart Road from Vail Way to Coffee Road, as well as the north half of Avon Street easterly of Vail Way. Drainage Area 1 discharges its storm water runoff to a catch basin (CB #1) located at the T-intersection of Vail Way and Avon Street. Drainage Area 2 includes the south half of Avon Street, the entire north half of the Basalt Street, and a portion of Thornton Way and Coffee Road. Drainage Area 2 will discharge into a catch basin (CB #2) located at the T-intersection of Basalt Street and Thornton Way. As previously mention, the Future Park Site will self-retain per NOR. Drainage Area 3 includes the southerly half of Basalt Street from Coffee Road to Thornton Way but does not include the Future R-1 Site. Catch basins #3 & #4, located at the knuckle of Creede Street and Thornton Way, will collect runoff produced by Drainage Areas 3 & 4. Drainage Areas 5 & 6 discharge runoff into two catch basins (CB #5 & CB #6) located at the four-way intersection of Estes Park Street and Rangley Way. Drainage Areas 7, 8 and 9 each surface flow to three separate catch basins (CB #7, CB #8 & CB #9) located at the T-Intersection of Grandy Street and Rangley Way. Runoff produced by Drainage Area 10 is collected in a catch basin (CB # 10) located at the T-intersection of Northglen Way and Grandy Street. Drainage Area 11 collects runoff in a catch basin (CB #11) at the T- intersection of Northglen Way and Kowa Street. Three separate catch basins (CB # 12, CB #13, & CB #14) located at the T-intersection of Kowa Street and Nederland Way collect runoff from Drainage Area 12, 13 & 14. Drainage Areas 15 through 18 discharge runoff to four separate catch basins (CB #15 through CB #18) located at the four-way intersection of Nederland Way and Moffat Street. Drainage Areas 17 & 18 both utilize a composite runoff coefficient as they each accept runoff from Snow Road. A 30” RCP line has been designed to run easterly along Moffat Street to provide a connection to the proposed system for the future development. The future development areas are currently zoned for R-1 (Single Family), R-2 (Limited Multi-Family), and Commercial (See Drainage Exhibit for a breakdown of acreages). The proposed retention basin is located at the southwest corner of the project and has been sized to handle all of the discharge from Tracts 6968, 7264, & the Future Residential and Commercial developments. The proposed sump will have a bottom elevation of 390.00 with a Design Water Surface of 399.50. The total area contributing to the proposed basin is approximately 151.95 acres with a required sump capacity of 11.44 acre-feet (AF). The required basin volume was calculated using the City of Bakersfield sump volume equation for the 24-hour 100 year storm (V=0.15 x Ʃ (CxA)). The proposed sump has been design to provide a volume of 12.03 AF. The various areas included in this study and their corresponding runoff coefficients are shown below and on the Basin Exhibit.

The attached Time of Concentration (Tc) Calculations were then used to determine the longest time of concentrations for each Drainage Area in a 10-year event. The longest Time of Concentration (Tc) for each drainage area was then used to calculate the corresponding rainfall intensity for the 10-year storm per the City’s IDF Curve (Plate D-1). The flows were then calculated using the Rational Method and were routed through each of the respective systems. The total flows in each pipe were then entered in Hydraflow Storm Sewers 2017 to help module the systems hydraulically. Hydraflow Storm Sewers calculates the HGL in each pipe given the starting HGL, the flow in each pipe, and the pipe slope/inverts. The starting HGL for the outfall pipe, Pipe 1, was modeled to start at the mid design depth elevation (394.75) of the proposed retention basin. Two Temporary Sumps will also be required to collect runoff not captured by the proposed Drainage System. Both Temporary Sumps have sized using the City of Bakersfield Sump Volume Equation (V=0.15 x Ʃ (CxA)). The first temporary sump will be located at the Northwest corner of the project and will be removed with the construction of Tract 7264. This temporary sump has a total contributing area of 0.85 acres with a runoff coefficient of 0.95. The first temporary sump has been designed to store 0.13 AF of runoff with a required volume of 0.12 AF. The second temporary sump is located at the south easterly tract boundary along Coffee Road and will be removed with the future development of Coffee Road. This temporary sump has a total contributing area of 0.88 acres with a runoff coefficient of 0.95. The second temporary sump has been designed to store 0.135 AF of runoff with a required volume of 0.13 AF. Both of the temporary sumps shall have a maximum depth of 1.5’ and can be seen on the attached Temporary Sump Exhibit. Tract No. 6968 DRAINAGE STUDY 6 4.0 CONCLUSION AND RECOMMENDATIONS The main objective of this study was to design an economical storm drain system for the proposed project that meets the design standards set forth by the City of Bakersfield. The storm drain systems outlined in this study will be able to handle all runoff produce by the project area in a 10-year storm event. The City of Bakersfield’s 10-year storm event was used in this study to calculate the anticipated storm water runoff produced by this project. The storm water was then routed through the proposed drainage system to determine the pipe sizes required to convey the runoff to the onsite retention basin. The Basin Exhibit and Basin Sizing Calculations, part of this study, show that the basin has been designed in accordance with the City of Bakersfield’s guidelines. The basin will have a total design water depth of 9.5’ with a minimum of 1’ of freeboard. The proposed site is estimated to require a sump capacity of 11.44 AF while the retention basin has been designed to provide 12.03 AF of available storage. Therefore, the proposed basin has an additional 0.59 AF of capacity then is required by the City of Bakersfield. In accordance with the City’s Development standards, the beginning Hydraulic Grade Line (HGL) was modeled to start at the mid design depth elevation (349.75) of the basin at the outlet structure(s). The HGL for the porposed system is not less than 0.5’ below the proposed finished surface elevation at any manhole or inlet. All the pipes in this system have been sized to be either 18” RCP, 24” RCP, 30” RCP, or 36” RCP.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.
