1.0 Introduction
1.1 Purpose
On the Coppell City Council approved funding for
a study of the drainage problem in the back yards of the 100 block
of Oak Trail. The purpose of this report is to present the findings
of the study and recommendations for consideration by the City.
1.2 Problem Statement
The homeowners residing at 141 and have reported that their
backyards flood several times each year. It appears that runoff from
the other backyards along the street ponds in these two lots to a
depth of as much as 5 feet during heavy rains.
2.0 Summary of Data
2.1 Homeowners
Information regarding the history, nature and extend of the flooding
problem was provided by homeowners. A summary of their input
follows:
a. Several times each year during heavy rains, the backyard of 1~,1
Oak Trail floods to a depth of 4 to 5 feet. There appears to be
no outlet for the runoff into this lot.
b. The water often backs up into the adjacent lot, __
Oak Trail.
c. Prior to the construction of the Summer Place Addition to the
west, the lots did not flood.
d. During heavy rains the ditch along the west side of Oak Trail fills
up until it crests the road in front of __ Oak Trail.
Prior the filling of the lot at __ Oak Trail, the ditch emptied
through a swale in that lot and discharged in the gravel pits in
the area now occupied by the Summer Place Addition.
The elevation of Oak Trail has been raised by recent resurfaclng;
therefore, the drainage problem in the ditch along the west side
of the roadway has been aggravated.
2.2. Design Documents
Review of the design drawings for the C0ppell High School and the
Summer Place Acldltlon provided the following information:
The drainage design for Summer Place Addition does not account
for offsite drainage from the east.
The drainage design for the Coppell High School accounts for
future runoff from the area nominally bounded by Summer Place
Addition to the west, Sandy Lake Road to the south, Shady Dale
Lane to the east and Willow Lane to the north.
The existing wye inlet near the southeast corner of the school
property has a 48-inch diameter stubout to the southwest for
future drainage of the area described in b. above.
2.3. Field Survey and Reconnaissance
A field survey was performed to determine key elevations used in the
study of existing conditions and the evaluation of possible solutions.
Orainage divides shown on design drawings were verified by field
survey.

Proposed Solution
3.1 OPTIO~I 1 Interim Solution A
A solution to the specific problem at 141 Oak Trait would be the
construction of an inlet in the backyard and a storm sewer along Oak
Trail and Willow Lane discharging into the existing wye inlet on the
high school site.
3
The drainage area to the proposed inlet as shown on the Coppell high
School plans would be 6.5 acres. Using a 15-mlnute time of concen-
tration, an intensity of 9.8 in/hr and a runoff coefficient of 0.45 for
SF-12 zoning, tlqe flow rate would be 29 cfs.
The probable construction cost for Option 1 would be:
"Wye" Inlet 1 @ $3,000.00 $ 3,000.00
33" RCP 850 I.f. @ $50/If 42,$00:00
$ 45,500.00
3.2 OPTION 2 - Interim Solution B
An alternate to Option 1 would be to construct an additional inlet in
the Iow point of the ditch along the west side of Oak Trail. The
storm sewer would then be sized to accommodate the area between Oak
Trail and Summer Place Addition.
The probable cost of Option 2 would be:
"Wye" inlets 2 @ $3,000.00 $ 6,000.00
33" RCP 200 I.f. @ $50/If 10,000.00
36" RCP 650 I.f. @ $60/If 39,000.00
$ 52,000.00
3.3 OPTION 3 - General Solution
A general solution to the problems identified in previous sections
would be to design a storm sewer main along Oak Trail and Willow
Lane for ultimate runoff from OA-2 and OA-4 as designated on the
Coppell High School Drainage Area Map. In addition to the "wye" inlet
in the backyard of 141 Oak Trail, an additional "wye" inlet would be
constructed at the Iow point of the ditch along the west side of Oak
Trail. If future improvements of Oak Trail, Willow Lane, and Shady
Dale included curb and gutter, the main would already be in place.
The probable construction cost for Option 3 would be:
"Wye" Inlets 2 La $3,000.00 $ 6,000.00
48" RCP 300 l.f. @ $90/If 27,000.00
36" RCP 350 I.f. La $60/If 21,000.00
33" RCP 200 I.f. @ $50/If 10,000.00
$ 64,000.00
3.4 Summary
Three options have been presented, all of which would solve the
immediate problem in the backyard of 141 Oak Trail.
