DRAINAGE ANALYSIS FOR
ONE WELLINGTON PLACE
BEAUMONT, TEXAS
OBJECTIVE:
The purpose of this study is to evaluate the stormwater drain-
age conditions on a proposed 23.9 acre multi-family residential
(M.F.R.) development in regards to the possibility of increasing
flooding on Hillebrandt Bayou, adjacent to the site. An eval-
uation was made to determine what drainage and detention facilities
would be necessary in order to reduce any chance of increasing
flooding along Hillebrandt Bayou.
GENERAL:
The site is located in northwest Beaumont, Texas, between
` Dowlen Road and Hillebrandt Bayou. The proposed development is
split into two sections, divided by a county drainage ditch which
crosses the property. Section One, consisting of 8.5 acres, lies
i
( north of the drainage ditch and is proposed to have strictly
multi-family townhomes. Section Two, consisting of 15.4 acres, lies
south of the drainage ditch and is proposed to have 10.9 acres
developed into multi-family residential (M.F.R.) and 4.5 acres into
single family residential (S.F.R.) (minimum 5,000 sq. ft. lots) .
At present the land is heavily wooded with thick grass cover
and underbrush. The soil is typically Beaumont clay, highly
impervious near the surface. The majority of the storm runoff
presently enters the county drainage ditch crossing the property
before it reaches Hillebrandt Bayou.
DANNENSAUM ENGINEERING CORPORATION
�v
DESIGN CONSIDERATIONS:
The primary consideration is to determine the capacity of the
necessary stormwater detention basins. These basins will hold any
excess runoff caused by the development of the area. In order to
enhance the aesthetic qualities of the development, these detention
basins will be incorporated into part of the recreational
facilities. The current concept is to depress the tennis courts and
slope the sides and use them as the detention basins. This concept
is not new, but has been used in other areas of Texas on a larger
scale with great success. .
The tennis court detention basins will be designed to hold only
the excess runoff from storms of a large return frequency. The
smaller storms will pass through to Hillebrandt Bayou without any
detention. In this manner, the basins will be usable except for
very large storms.
The storm used in this design report has a return frequency of
once every one-hundred years. This is referred to as a 100-year
frequency storm.
r DANNENSAUM ENGINEERING CORPORATION
a
DRAINAGE ANALYSIS:
s _ The development will utilize an underground storm sewer drain-
age system to collect runoff and discharge it into Hillebrandt
Bayou. However, any excess runoff due to development will be stored
in stormwater detention basins, to be located on site, and released
into Hillebrandt Bayou as the flow in the channel subsides.
In order to properly design the detention facilities for this
site, additional information concerning Hillebrandt Bayou must be
obtained. That is, the length of time it takes for Hillebrandt
Bayou to reach its peak flow level and the elevation of the peak
water surface for the design storm frequency are necessary. In
order to obtain this information, an extensive engineering analysis
of the Hillebrandt Bayou watershed will need to be performed. This
analysis should include a hydrologic study and flood routing
analysis of the watershed and a water surface profile analysis on
Hillebrandt Bayou. It is recommended that the U.S. Corps of
Engineers computer programs HEC-1 and HEC-2 be utilized for these
studies.
Since this is a preliminary engineering design study, these
major studies were not performed for this report. However, before
final design plans can be prepared, the hydrologic and hydraulic
studies on Hillebrandt Bayou must be performed.
For this- report, a "worst case" condition was assumed, which is
that during a 100-year frequency storm, Hillebrandt Bayou rises
DANNENBAUM ENGINEERING CORPORATION
F ° immediately, that the flow level reaches the top of bank, and that
the flow level stays at the top of bank throughout the duration of
the storm event. Although this is a conservative approach, a prac-
tical design of the stormwater detention facilities cannot be done
without the additional data.
Although the development of a 23.9 acre tract of land will
probably not affect the water surface in Hillebrandt since it car-
ries runoff from over 3,000 acres of land upstream of the site, the
analysis in this report was based on designing the detention facili-
ties to store all stormwater runoff on the site in excess of the
stormwater which is running off under the present undeveloped condi-
tions. Simply, a calculation has been made of the total volume of
stormwater which becomes runoff under present conditions and the
,
total volume of stormwater which would become runoff for the pro-
posed multi-family development. Then, the difference in these
volumes is the maximum volume of on-site storage necessary to avoid
any possible increase in runoff into Hillebrandt Bayou.
The procedure used to develop runoff volumes was the method
currently used by the Soil Conservation Service (SCS) for small
watersheds (less than 2,000 acres). The procedure is outlined in
Technical Release No. 55 entitled "Urban Hydrology for Small Water-
sheds". This procedure takes into consideration the type of soil ,
land use, and amount of rainfall for specific locations within the
United States.

CONCLUSION:
The calculations conclude that, for a "worst case" situation,
1.69 acre-feet of detention storage is required for Section One and
2.93 acre-feet of storage is required for Section Two. As shown on
the land plan and storm sewer layouts, in the appendix of this
report, the tennis courts, constructed approximately 6 feet below
ground, will be interconnected with the storm sewer network in such
a manner that the excess runoff can back up into these basins. The
tennis court detention basins are sized to have the above mentioned
capacities, providing storage for runoff in excess of existing
condition runoff for a 100-year frequency/24 hour duration storm.
It is anticipated that, after an extensive evaluation of Hille-
brandt Bayou during final design, additional data would be utilized
i
that could allow for a reduction in storage volume for this pro-
ject. At this point, however, the design in this report will pro-
f.
vide a stormwater drainage system that will not cause any increase
of runoff into Hillebrandt Bayou which may worsen flooding condi-
tions presently experienced on this stream.
