Please let me know if you have any questions or need anything further. t
CERTIFICATION
I hereby certify that this report for the drainage design of the Gateway Subdivision was prepared under my
supervision in accordance with the provisions of the City of College Station Drainage Policy and Design
Standards for the owners thereof.
.
INTRODUCTION & BACKGROUND
Gateway Subdivision is located at the northwest comer of FM 60 (University Drive) and SH
6 Bypass. The property consists of 76.12 acres divided into 8 lots and two Reserve tracts. A
final plat for Lots 1 -8, Block 1 of the Gateway Subdivision was approved by the City of
College Station in August 1999. This final plat includes two primary access easements,
which provide access to all lots within the subdivision. One easement will contain a 46-foot
boulevard section roadway, connecting to University Drive opposite Glenhaven Drive
forming a four-way intersection at this location. The other access easement is along the rear
property line of all lots within the subdivision. This easement will contain a 30-foot access
drive, which will connect on the eastern end to the new boulevard section. The purpose of
this drainage report is to analyze the effects of the improvements associated with the two new
access roadways on the surrounding drainage system, as well as discuss the impacts of
undetained runoff from the development on Lot 6, Block I (Texas Roadhouse site) entering
the system.
PREDEVELOPMENT DRAINAGE
The property generally drains in three directions, all of which terminate at Burton Creek.
The western portion of the property drains to a tributary of Burton Creek located at the far
northwestern property comer. The center of the property drains roughly due north toward the
rear portion of Lot 1 of the Gateway Subdivision, while the eastern portion of the property
drains in a northeasterly direction to a channel which runs through Lots 2 & 4 and Reserve B.
This channel along the northeastern portion of the property accepts runoff from a large
drainage area upstream of University Drive. It accepts runoff from approximately 28 acres,
which includes the Glenhaven Subdivision and the Scott & White Clinic complex.
West Drainage
The pre-developed drainage area to the west consists of approximately 6.2 acres.
Predevelopment runoff rates for the 2-year through the 500-year storms were computed for
Drainage Area 1 at Study Point 1, shown on Figure l. The runoff was computed using the
SCS method within the HEC-1 program and the HEC analysis is included in Appendix A.
Table I includes all lag time calculations for the SCS method for all pre and post-
development areas. The results from the HEC-1 analysis for each storm event have been
compiled within Table 2.
East Drainage
The pre-developed drainage area for the eastern portion of this site consists of approximately
34. 7 acres of which 28. 4 acres is fully developed at the present time. Predevelopment runoff
was computed for Drainage Area 2 as shown on Figure 1. The runoff from the eastern
drainage area was studied at two locations, Study Points 2 & 3. This was done to illustrate
the effects of the new improvements at a point just downstream of the proposed
improvements as they enter Lot 2 of the Gateway Subdivision and also at a location where
the total drainage area is equivalent in both the pre~ and post-development scenarios.

POSTDEVELOPMENT DRAINAGE
Overall Drainage Plan
The 76 acre Gateway Subdivision will be providing a regional detention facility at the rear of
Lot I with future development. This analysis and design will be included with the
development of Lot I and may provide additional detention for other lots within and outside
the subdivision, as property negotiations may warrant. The analysis contained herein is not
intended to include the design for the regional detention at this time, but is included as a
discussion item only. The flow from these driveway access improvements and the additional
runoff from Lot 6 (Texas Roadhouse site) will ultimately flow to and be accepted by the
regional detention pond once created. The system designed herein is intended to work within
this master plan concept.
West Drainage
The post-developed Drainage Areas land IA consist of approximately 6.3 acres, an increase
of approximately . I acres over the pre-developed conditions. This is due to the access drive
intercepting a small portion of the drainage area, which flowed toward the north, and
diverting it to the western tributary. This diversion is only temporary as once the flow enters
Burton Creek, the runoff increase due to the change in drainage areas compensates for itself
Post-development runoff rates for the 2-year through the 500-year stonns were computed for
Drainage Area I and IA at Study Point I, shown on Figure 2 . The runoff was computed
using the SCS method within the HEC-1 program and the HEC analysis is included in
Appendix A The results from the HEC-1 analysis for each storm event have been compiled
within Table 2 .
Open Channel along Western Property Line
To intercept the flow from the new access drive, a small swale will be graded along the
westernmost property line from the end of the access drive to the existing channel at the
northwestern property comer. This swale will have a 1.5 foot high berm along the property
boundary to prevent overflow from the swale entering the adjoining property. The swale has
a 2 foot bottom width with 4 :1 side slopes and is 1.5 feet deep . This configuration will have
capacity to convey the 25 year storm event as seen on Table 5.
East Drainage
Texas Roadhouse
Texas Roadhouse Cafe currently has submitted plans for review and approval with the City
of College Station for site development on Lot 6, Block I of the Gateway Subdivision. Their
drainage report illustrates that they will be detaining most of their increased runoff on their
lot, however a small portion of their increased runoff enters the rear access drive and is
captured by the Gateway underground storm drain system. The HEC-1 analysis contained
_herein accounts for Yi of this site (.8 acres) entering the system undetained at a CN of94.
This is a conservative assumption given that the current drainage analysis for their site
detains more than 800/o of their increased runoff within on-site facilities.
4
Glenhaven Drive (Gateway Private Boulevard)
The pre-developed drainage patterns for Lot 5, Block 1 are toward the west with a large
portion of the lot being carried through an existing swale toward University Drive and
entering the creek close to the right-of-way of University Drive. This drainage pattern has
been retained in this design. To accommodate this flow, a driveway culvert under the
Gateway Private Boulevard and a cwb cut on the western edge of the boulevard has been
provided. The curb cut is to allow a small portion of Lot 5 to be canied across the Boulevard
section to the downstream system. The runoff from Lot 5 and the upstream drainage area 4,
as seen in Figure 2, will be carried within the culvert system parallel to the University Drive
right-of-way. With the upcoming widening of University Drive, a new storm drain system
will be constructed parallel to this new culvert. Because of this situation, a meeting with
TxOOT was held to see if there were possibilities to reduce the redundancy of this system.
Timing of this project compared to the timing of the anticipated widening, coordination
efforts and the political difficulties of a "shared" system prevented this from occurring.
Therefore, this design allows for a separate private driveway culvert that will run parallel to
the upcoming TxOOT storm drain system. The calculations for the pipe size are included in
Table 4 and show that a 21" pipe at a minimum .39°/o slope is required to accept flow for the
10-year storm event from drainage areas 4 and 5, as shown on Figure 2 . The design
contained herein call for a 24" pipe at 1.8%, meeting the minimum required.
Rear Access Drive
The rear access drive consists ofa 30-foot wide concrete center drain street section. It has
3.33% slopes toward the center, with a center depth of 6-inches. As the rear access drive
approaches Glenhaven Boulevard a 30" slotted drain intercepts the runoff prior to it entering
the intersection. The 30" slotted drain is designed for the 10-year storm event with all storm
events greater than this being contained within the access drive. The runoff calculations for
this slotted drain include full development runoff from drainage areas 3 and 8. Table 4
shows that for a I 0-year storm event, the slotted drain required is a 24" pipe at a minimum
slope of 2.36%. The design contained herein provides a 30" slotted drain at 3 . 73%, meeting
the minimum required.
The slotted drain will discharge into an RCP system, which will carry it to Study Point 2 as
illustrated on Figure 2 . Calculations for this RCP system are also shown on Table 4 . The
RCP system will pick up an additional drainage area 9 through a grate inlet constructed at the
end of the access drive behind Lot 4, Block 1. This grate inlet is intended to pick up the
small drainage area 9 and convey it underground to Study Point 2 . The required size and
slope for the RCP system for the I 0-year storm event is a 24" pipe at a minimum slope of
2 .32%. This design provides a 24" pipe at a minimum of2.4%, meeting the required pipe
capacity.

PRE-vs. POST-DEVELOPED RUNOFF
The following table illustrates the pre-and post-development flow from the site at the three
different study points. Although there are slight increases at each study point, the effects are
negligible given the floodplain and large upstream drainage area that exists at this location.

FLOW PATH/FLOODPLAIN
West Drainage
The increase to the West Drainage system is I cfs for all storm events. This increase is
contained with the limits of the regulatory floodplain and carried to the primary channel. It is
minor compared to the overall drainage flows in this tributary of Burton Creek and therefore
does not adversely affect adjoining properties.
East Drainage@Study Point 2
The comparison of flows in Table 2 show an increase of 6 cfs for the 2-year event and an
increase of 14 cfs for the 100-year event at this Study Point. As part of the negotiations for
this property, the developer of the Gateway Subdivision obtained a non-exclusive drainage
easement across Lot 2, Block I of the Gateway Subdivision. The developer requested this
easement to provide for a path for the increased runoff from these improvements to cross Lot
2, Block I . This easement is contained within the Special Warranty Deed shown in
Appendix B. The increase in flow at Study Point 2 is caused by two factors. One is the
increased impervious cover within the drainage area but more importantly due to the change
in pre-vs. post-drainage areas to this point. As seen in Table l , there is a 1.6 acre increase
in drainage area from Drainage Area 2 Pre and Drainage Areas 2-9 Post.
East Drainage@Study Point J
In an effort to more accurately quantify the increased runoff created by these improvements,
the analysis includes Study Point 3 . At this point in the system, the pre-and post-developed
drainage areas are again equal. The results from Table 2 now more accurately quantify the
increase, which is 3-5 cfs for the 2-year through 100-year events. This is roughly a 1.5%
increase in flows for these storm events. The l 00-year floodplain in this area of the property
almost fully inundates Reserve "B" where this increase will be seen. The flows in Burton
Creek at this location from the Flood Insurance Study are 7,950 cfs for the IO-year event and
11,600 cfs for the 100-year event. When compared to this magnitude of flow at this location,
the increase recognized from these improvements is even smaller, on the order of .05%.
CONCLUSION
The runoff from the access drive improvements for the Gateway Subdivision as well as the
additional runoff from Lot 6, Block I (Texas Roadhouse site) is negligible within the given
drainage system. The developer. of the Gateway Subdivision has secured from Lot 2 , Block I
a non-exclusive drainage easement for the increased runoff that Lot 2 will recognize. As the
flow continues downstream to the next property, the increase in runoff volume is reduced due
to the equaliz.ation of pre-and post-drainage areas. The increase in runoff that is calculated
is diminished by the magnitude of flow in the Burton Creek primary system that exist on the
property.
