Hydrology Study
Purpose of Hydrology Study
The purpose of the following Hydrology Study is to determine the on-site flows pertaining to the
proposed Generations Truck Sales Addition/Expansion Development, located at 15848 Slover
Avenue in the City of Fontana, CA. The site is currently 100% developed as a truck sales
facility, is approximately 1.64 acres in size and drains to the southwest corner of the property.
The proposed addition/expansion will include the building of new structures, landscape areas,
gutters, walls, underground infiltration chambers, and storm drain pipe on the existing facility
(note that the impervious ratio will not be altered). Also note that the existing and proposed
block walls running along the east and north property lines effectively shield the site from any
tributary flows.
This study will evaluate the 1 -hour, 10 -year storm return frequency and 1 -hour, 100 -year storm
return frequency flow rates for existing and proposed conditions, and will evaluate the drainage
improvements and requirements for proposed addition/expansion.
In addition, this study also evaluates the stormwater runoff for existing and proposed on-site
conditions in order to determine the required retention capacity for the on-site flows.
The following aerial photo shows the proposed project site location and boundaries:

2.0 Watershed Description
The on-site area for the proposed project site is located in the City of Fontana within the Santa
Ana River Reach III watershed. All flows from the project site drain to the Bly Channel by way
of Slover Avenue; the Bly Channel discharges to Santa Ana River Reach III.
.. 3.0 Methodology
This study utilized the procedures outlined in the San Bernardino County Hydrology Manual
�. dated August 1986. The CIVILDESIGN® software was used in the preparation of this study.
Pursuant to the manual, The Rational Hydrology Method was selected for all calculations due to
-� the relatively small acreage of the on-site drainage areas for the proposed project site. The
Rational Hydrology Method for the 1 -hour, 10 -year storm return frequency and 1 -hour, 100 -year
storm return frequency was used to determine the on-site area flow rates the existing and
�- proposed conditions.
The Unit Hydrograph Method for the 100 -years storm return frequency was used to determine
the runoff volume generated by the existing and developed conditions of the proposed project
site. The volume capacity requirements for the on-site retention basin design were estimated
using the increase in runoff volume between the existing and proposed on-site conditions with an
additional 10% of the existing conditions.

The San Bernardino County Hydrology Manual, Section C, shows the drainage area consists
of Soil Group "A". The development type used in this study for both existing and proposed
conditions was considered to be "Commercial" with a pervious ratio of 0.10, or the
equivalent of 90% paved surface and proposed buildings. Please see Attachment No. 4 for
Hydrologic Soils Group Map.

peak flow rate of 6.54 cfs with a runoff volume of approximately 1.00 acre -ft.
The results of the Unit Hydrograph calculations for the on-site existing conditions are tabulated
as follows:
Table No. 4
6.2 Developed Conditions:
The 100 -Year, 24 -Hour Unit Hydrograph calculations for the on-site proposed conditions show a

6.3 Retention Volume Requirements:
Because the project does not entail any increase in impervious area, there is no increase in
volume between existing and proposed conditions. Therefore, 10% of the exiting conditions
volume of 1.00 acre-feet is required by the City in order to determine the total minimum storage
retention volume capacity. Therefore, the target capture volume is 10% of 1.00 acre-feet, or 0.10
acre-feet. Pursuant to the Water Quality Management Plan (WQMP) for the project prepared by
Joseph E. Bonadiman & Associates, Inc. dated October 2, 2007, the underground infiltration
chambers proposed for the project have been sized to retain a total volume of 0.19 acre-feet,
which is more than adequate to retain the target capture volume. This will therefore result
in an overall volume reduction of 0.19 acre-feet between existing and developed conditions.
7 Hydraulic Analysis
In order to contain the on-site stormwater runoff and direct it toward the proposed underground
infiltration chambers, this study proposes a storm drain system that consists of curb inlet catch
basin that conveys flow to a proposed 12" RCP storm drain pipe that in turn drains to the
proposed underground infiltration chambers. Pursuant to the Proposed Conditions 100 -year 1 -
hour Rational Method calculations (see Attachment No. 6), the minimum pipe size necessary to
convey the 100 -year peak flows is 9". Therefore, the proposed 12" pipe will be adequate for the
flow rates in question.
8 Conclusion
The proposed Generations Truck Sales Addition/Expansion in the City of Fontana, CA will not
result in any significant increase or decrease in on-site runoff volumes for 10 -Year and 100 -Year
conditions.
Because the impervious fraction of the project site will not change between existing and
proposed conditions, the total site runoff volume of approximately 1.00 acre-feet will remain
unchanged between existing and developed conditions. The proposed infiltration chambers
capacity of 0.19 acre-feet is more than adequate for retention and infiltration of 10% of existing
conditions volume, and will serve to reduce the proposed conditions runoff volume from 1.00
acre-feet to 0.81 acre-feet.
The proposed Generations Truck Sales Addition/Expansion in the City of Fontana, CA will not
adversely affect areas downstream from the project site.
