DRAINAGE REPORT
CRYSTAL PARK PLAZA
STORAGE BUILDING
COLLEGE STATION , BRAZOS COUNTY, TEXAS
JULY , 1997
The site of the proposed improvements is located along the
State Highway 6 frontage road between Mile Drive and F.M. 2818.
The site has an existing office complex refered to as "Crystal
Park Plaza" and is 9 .07 acres in size . The proposed improvements
to the site include pavement, drainage and utility improvements
for the construction of a 4000 square foot storage building which
will be used by tenants of the complex and will be constructed
behind the existing office b u ilding. The terrain in the area of
the proposed i mprovements slopes in a northwesterly direction
toward an existing channel at approximately four percent. The
latest Federal Emergency Management Agency (FEMA) Flood Insurance
Rate Maps (48041CO 142c) shows tha t a portion o f the 9.07 acre
tract is in the regulatory 100-year flood plain however no
portion of the proposed improvement s will be in the flood plain.
The site is zoned C-1 (commercial) and is being developed by Mr.
Scott Eidson, Karbrooke , Inc. 2 70 0 East Bypass , Suite 2000,
College Station, TX 77845, (409) 693-2467.
EXIST ING DRAINAGE BASIN DESCRIPTION :
The entire site ( 9. 07 acres) discha rges directly into Bee
Creek Tributary "A" Drainage Basin No. 4, Regu latory Channel
Reach No. I which is a primary channel. This reach of Bee Creek
is not in a 11 Special Drainage Basin and Channel Reach Design
Standard ", Item D, of the College Station "DRAI NAGE POLICY AND
DESIGN STANDARD ", page 1 0 , requiring d etention by ordinance.
However this reach does re qu ire tha t the Minimum Floor Elevation
be Base Flood plus 2 feet (page 11) .
The drainage basin upstream of this site is approximately
1100 acres and the ditch section a t the upstream property line
has a substantial flood plain width, at places being
approximately 300 feet wide. The creek has a small pilot channel
which is on a very flat slope.
The FEMA Flood Insurance Study (FIS), flood profiles (page
22P) show that t he BFE varies along the site from 254.00 at the
downstream section of the site to 256.00 at the upstream section
of the site. This is based on existing conditions of July, 1992 .
Section "A" of the profile (22P) is at the upstream section of
the property . A drainage map has been included for review.
PROPOSED DRAINAGE :
The grading of the i mprovements will route the water in the
same pathway as existing condition s. The finished floor elevation
of the storage building will be four feet above the base flood.
An analyzes using HEC-RAS was prep ared to determine any
change in the water s u rface elev a t ion of the creek due to the
proposed improvements. Below is a table showing a summary of the
results before and after the proposed site development .

-A tail water surface elevation of 249. 00 at Bee Creek Main
Channel was used to coincide with the FEMA data.
The table shows that the additional flow
proposed improvements will not change the water
and therefore, detention is not required nor
site. Storm runoff calculations for pre and
conditions has been included for review.
CONCLUSION:
generated by the
surf ace elevation
planned for the
post-development
This project is in compliance with the City's Stormwater
Design Standards.
