DRAINAGE REPORT
CASTLEGATE SUBDIVISION -SECTION 13
INTRODUCTION
The purpose of this report is to pro vide the hydrological effects of the construction of the
infrastructure for the Castlegate Subdivision, Section 13, and to verify that the proposed storm
drainage system meets the requirements set forth by the City of College Station Drainage
Policy and Design Standards.
GENERAL LOCATION AND DESCRIPTION
The project is located on a portion of a 111.46 acre tract located west of State Highway 6 a long
the north side of Greens Prairie Road in College Station, Texas . This report addresses Section
13 of this subdivision , which is made up of 6.238 acres. The site is pastureland with
approximately 30 % of the area wooded with oak trees and yaupons. The existing ground
elevations range from elevation 300 to elevation 310 . The general location of the project site is
shown on the vicinity map in Exhibit A.
FLOOD HAZARD INFORMATION
The project site is located in the Spring Creek branch of the Lick Creek Drainage Basin. Most
of the proposed developed area of the site is located in a Zone X Area according to the Flood
Insurance Rate Map prepared by the Federal Emergency Management Agency (FEMA) for
Brazos County, Texas and incorporated areas dated February 9, 2000, panel number
48041C0205 -D . Some of the proposed residential lots are partially in Special Flood Hazard
Area, Zone AE, as shown on the panel. This area is shown on Exhibit A as the 100-year
floodplain limit. Also shown on this exhibit are the floodplain limits as determined by the
Castlegate Floodplain Analysis Report which was previously submitted. The rear portions of
some of the residential lots in Section 13 are within the 100-year floodplain limits. However,
the floodplain limit determined by the Castlegate Floodplain Analysis results in less of the lot
area being in the Flood Hazard Area. The majority of the Flood Hazard Area has been
designated as Common Area, which will have no development and it will be left in its current
condition.
DEVELOPMENT DRAINAGE PATTERNS
Prior to development, the storm water runoff flows easterly until it enters the floodplain and
then into Tributary D of Spring Creek. Ultimately, the runoff flows in Spring Creek and then
north to the regional detention facility. Refer to the v icinity map on Exhibit A for the location
of this facility .
DRAINAGE DESIGN CRITERIA
The design parameters for the storm sewer are as follows:
• The Rational Method is utilized to determine peak storm water runoff rates for the storm
sewer apron & flume design.
3
• Design Storm Frequency
Storm Sewer system 10 and 100-year storm events
• Runoff Coefficients
Pre-development
Post-development (single family residential)
c = 0.30
c = 0.55
• Rainfall Intensity values for Brazos County for a minimum time of concentration of 10
minutes can be found in Table 1. Where a longer time of concentration was necessary, it is
noted in the respective table, and the intensities are calculated with the higher values where
required.
• Time of Concentration, tc -Due to the small si z es of the drainage areas , the calculated
times of concentration, tc, are less than 10 minutes . Therefore, a minimum tc of 10 minutes
is used in most cases to determine the rainfall intensity values. Where a longer time of
concentration was necessary, it is noted and used accordingly.
STORM WATER RUNOFF DETERMINATION
The peak runoff values were determined in accordance with the criteria presented in the
prev ious section for the 5 , 10 , 25 , 50, and 100-year storm events. The runoff coefficients are
based on the future development of this tract. Exhibit B shows the post-development drainage
areas for the storm sewer apron and flume designs . Post-development runoff conditions are
summarized in Table 2.

The detention facility handling the runoff from this site is a regional facility designed by LJ A
Engineering & Surveying, Inc . Also, a detention pond was constructed upstream of Castlegate
Drive to reduce the peak flow resulting from the Castlegate development. In Exhibit A, the
location of the regional detention facility is shown on the vicinity map, and the detention pond
is shown upstream of Castlegate Drive. The runoff from this project flows into existing
drainages and then into Spring Creek. The regional detention facility is located adjacent to
Spring Creek prior to Spring Creek entering the State Highway 6 right-of-way.
STORM SEWER APRON & FLUME DESIGN
There will not be any storm sewer piping for this project. However, there will be a concrete
apron to drain the gutter flow across the street where it will enter a concrete flume which will
take the runoff to the 100-year floodplain and then into Tributary D of Spring Creek.
Dissipater blocks will be constructed at the downstream end of the flume to reduce the velocity
of the water prior to entering the existing drainage.
The concrete apron will have a 5 ' bottom width with a slope of 1 % and side slopes of 2%. The
concrete flume will also have a bottom width of 5 ', but it will have a slope of 1.8 % with
vertical side slopes . The flume will be 8" in depth. Appendix A presents a summary of the
storm sewer apron and flume design parameters and calculations. These two features were
designed based on a 10-year design storm , and they pass the 100-year storm event as well.
The streets were designed to maintain a gutter flow depth of 5" or less. This design depth will
prevent the spread of water from reaching the crown of the road for the 10-year storm event.
The maximum depth of flow in the street gutter will be 2.61 ". The depth of flow in the
concrete apron will be 2 .04 ". However, the flow depth in the flume is 3.99'', which results in
the depth of water being 3.24 " in the apron. All of these values are for the 10-year storm event.
A summary of these flow depths are also shown in Appendix A.

CONCLUSIONS
The construction of this project will increase the storm water runoff from this site. The
proposed apron and flume should adequately control the runoff and release it into existing
drainages. As shown in the Castlegate Floodplain Analysis , the Castlegate Subdivision does
not have a significant effect on the 100-year floodplain water surface elevations or the
floodplain limits . Also , the regional detention facility should adequately control the peak post-
development runoff so that it will not have any impact on the properties downstream of the
Crowley Tract.
