1.0 PURPOSE
The purpose for this drainage study is as follows:
1. 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 to concentration (roof to gutter) are 15 minutes for R-1 Development.
2. Approximately a tenth of the site is Soil Group A - Cajon sandy loam, overblown, 0 to
2 percent slopes and the remaining area is Soil Group B - Kimberlina fine sandy
loam. The soil group was obtained from the US Department of Agriculture Soils
Survey. A Soil Map is enclosed with this report.
3. The runoff coefficients used are:
A. 0.15 - Park
B. 0.38 - R-1, 7,500 S.F.
C. 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.
3.0 DESIGN APPROACH
The contributing areas to the retention basin are all zoned residential and therefore were modeled
as such so that the improvements were accurate.
This report also studies the required pipe sizes for the main lines leading from Berkshire Road to
the retention basin. The project area for the storm drain improvements are dictated by the flat
terrain that is present. More specifically the improvements are designed to benefit all areas
bounded to the east by Old River Road, to the north by Tract 6536, to the south by Berkshire
Road and to the west by Tract 6916 that takes storm drain runoff into the Basin Drainage Area.
Berkshire Road and part of Old River Road (Area 1 and Area 2) will discharge all of its runoff into
two catch basins (CB #1 & CB #2) located at the intersection of Berkshire Road and Vogel Way.
Drainage Areas 3, 4, and 5 (CB #3, CB #4, & CB #5) will discharge catch basins located at the
intersection of Biscayne Drive and Varden Street. CB #6 will collect the discharge produced by
Area 6 at the intersection of Pipestone Drive and Varden Street. Drainage Areas 7 and 9 have its
own weighted coefficient value from portions of Old River Road and the residential lots. Drainage
Areas 7, 8, and 9 will discharge catch basins (CB #7, CB #8, & CB #9) located at the intersection
of Bidwell Drive and Bendigo Way. Two catch basins (CB #10 & CB #11) will be located at the
knuckle of Evansburg Avenue and Perpetua Way adjacent to the park which will collect the
discharge produced by Area 10 and Area 11. Drainage Areas 6 and 11 will have its own weighted
coefficient value from the park and the residential lots. The retention basin area consists of the
residential lots, park, and the two adjoining streets.

The flows for the sizing of the pipes were estimated utilizing the City of Bakersfield Rational
Method in accordance with the Subdivision Standards. Flows were computed for the 10-year
event 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 catchment’s area in acres. Since the
main purpose of this report is the storm drain system leading to the basin and the curb capacities
were determined based the 5-year storm event.
The proposed retention basin on the northwest corner of tract will be at a pad elevation of 348
and handle all of the discharge from tract. This basin will be expanded in the future. The required
sump capacity for Tract 6825 is 2.49 acre-feet (AF) but the allotted area for this tract can only
retain 1.38 AF. A 45' temporary easement extending into Tract 6536 will be required if Tract 6825
is developed first. Tract 6536 is a proposed R-1 development located just north of Tract 6825.
The provided sump capacity for Tract 6825 with a 45' temporary easement is 2.64 acre-feet (AF).
The required basin volume was calculated using the City of Bakersfield sump volume equation
(V=0.15 x Ʃ (CxA)). Per the City of Bakersfield’s request, the ultimate buildout basin volumes
(provided and required) were calculated. This basin will be expanded in the future to
accommodate the runoff from Tentative Tract 6536. The total contributing areas equal 78.50
acres; this acreage is divided into the areas as noted below. The area of the proposed basin was
omitted from this analysis. The coefficient values are provided for each area, and the calculations
for the required and provided volumes are shown below and on the Basin Exhibit.

* Assumed based on a plan provided by the City of Bakersfield
The rational method for the 10-year event was performed using Autodesk Storm and Sanitary
Analysis 2014. This program routes the flows and calculates the HGL for the system. The
program has the ability to calculate the time of concentrations, but it also allows you to enter your
own time. The time of concentration was calculated separately and entered into the program. A
spreadsheet similar to the curb capacity spreadsheet was used to determine the initial time of
concentrations in a 10-year event. The flows from the 10-year event were calculated and routed.
Starting HGL at the basin was estimated to be 4.5’ above the basin bottom.
5
4.0 CONCLUSION AND RECOMMENDATIONS
The flows from the 10-year event were calculated and routed. The beginning HGL was estimated
to be 4.5’ above the basin bottom at the outlet structure. All the pipes in this system were sized
to be 18” RCP, 24” RCP and 30” RCP. The HGL is not less than 0.5’ below the existing grade at
any manhole.
The main objectives of this study were to design an economical storm drain system and meet the
design standards set by the City of Bakersfield. The storm drain system will be able to handle a
10-year event. The Basin Exhibit, part of this study, shows the designed basin that allows for the
expansion to the adjacent northerly tract. The basin will have a total water depth of 9’ with a
minimum of 1’ of freeboard. The basin for only Tract 6825 will be able to store 2.58 AF of runoff.
The basin for the completed condition will be able to store 6.04 AF of water. The depth of the
basin is 15 deep with a water surface of 342. The required volume for both tracts is 5.09 AF
which has an excess volume of 0.95 AF.
