Re: Gateway Station Shopping Center Drainage Design
Dear Spencer,
The purpose of this letter is to analyze and document the required drainage
infrastructure for the proposed Gateway Station Shopping Center. The proposed site is
located on Lot 8, Block 1, Phase 1 of the Gateway Subdivision located on the north side of
University Drive and west of Wings 'n' More restaurant. No part of the 2.10-acre tract
lies within the FEMA regulatory 100-year floodplain as indicated in Exhibit A. As per the
City of College Station Drainage Policy and Design Standards (DPDS), the objective of
drainage improvements is to limit the post-development peak flow to the pre-development
peak flow by providing adequate detention. However, in this case, the developer of Lot 1,
Block 1 of the Gateway Subdivision has agreed to provide detention for the excess runoff
generated by the proposed Gateway Station Shopping Center. These calculations are
provided in the Drainage/ Detention Report for the Home Depot, completed by Bury &
Partners, Inc., August 2002. Excerpts from that report have been provided with this letter
to demonstrate the fulfillment of drainage requirements for the Gateway Station Center.
Because of the relatively small area of the proposed site, the rational method was used to
perform runoff calculations using a time of concentration of 10 minutes. The rational
method calculations for pre-and post-development runoff can be examined in Exhibit C.
The Bury & Partners report estimates the Rational Method runoff coefficient at C=0.90
for the drainage sub-basin that includes the Gateway Station Center. The Gateway Station
design results in a runoff coefficient of C=0.88, lower than the estimate. As shown in
Exhibit DMAP, the Gateway Station Center is subdivided into two drainage areas. The
first of these (PA-1) includes the parking areas and adjacent vegetated strips. The parking
area has been graded to drain the entire drainage area to a 10' curb inlet in the parking
area at the northwest comer of the site. The curb height on that side of the parking lot will
be increased to 7" in order to increase the inlet capacity. The flow will be carried to a
junction box (JBl) via a 21" RCP storm sewer. The second drainage area (PA-2) consists
of the Gateway Station Center building as delineated by the shaded footprint in Exhibit
DMAP. The runoff will drain toward the back of the building to an interior collection
point with two grate inlets. These inlets are connected with a 12" PVC and then routed to
JB 1 via a 15" PVC storm sewer. The flows from both drainage areas are joined at JB 1
and are carried to the curb inlet (CI2) located along the adjacent alley. Inlet CI2 will
collect flow from the alley contributed by the Wings 'n' More site and the alley (Refer to
drainage letter for Wings 'n' More restaurant, June 23, 2002). From the curb inlet, the
runoff will travel in a 30" RCP to its discharge point approximately 60' north of the alley.
All drainage infrastructure has been shown in the attached Exhibit DMAP. At the present
time, this flow will proceed overland to the detention pond. In the future with the
development of Lot IA, the flow will be collected in a future storm sewer system and
routed through the regional detention pond located behind Home Depot. Review of the
drainage analysis for the Gateway Station Shopping Center indicates that the drainage
design presented in this report properly accounts for detention and will provide adequate
conveyance to meet the drainage objectives of the City of College Station Drainage Policy
and Design Standards. If you have any questions or comments, please feel free to contact
