Prel~~Plat
Enclosed are three (3) copies of the Preliminary Plat,
Preliminary Utility Layout and Preliminary Drainage Plan.
identical package has also been forwarded to Shohre Danes~and
for review. These drawings, accompanied by this letter, will
address all ~own co~ents made on the subject of the Preliminary
Plat.
Those items not specifically addressed on these Preliminary
Drawings are as follows:
1. No cover sheet has been provided.
2. No "Construction Plans" have been provided.
These are not submitted at this time due to the preliminary
status of the plat. The Preliminary Drainage Plan has been
prepared in accordance with the direction of Ms. Shohre
Danes~and.
We are prepared to s~mit Construction Doc~ents in accordance
with City Criteria at the appropri~e time. _ .
According to ~. Bill ~derson, ~he'drainageUstudy being prepared
has been conceptually approved by, the City_of Coppell. We are in
recei~-of a ~l~/Froflle layout depicting the'proposed offsite
channel noted on our Preliminary Plat and Drainage Plan. This
plan provides for a channel to be constructed from the northwest
corner of the Food Lion tract to the southwest cgrner of Meadow
Ridge - Phase I Addition (approximately 600 feet). The
calculations for this channel indicate that it will provide
capacity for the developed runoff from the entire Co~ercial
Tract and a portion of the School Tract. The plan indicates a 42
or 48 inch diameter pipe outfalling at the northwest corner of
the Food Lion Tract at an elevation of 477.9~. Preliminary
Grading Schemes indicate a finished floor of 485! which will
provide for a dock elevation of 480.5~. In order to provide
sufficient cover for the outfall pipe, it will be necessary to
fill the open area behind the truck dock area and outfall at a
point slightly south of the property line as sho~ in the
attached sketch.

The drainage system within the Food Lion Tract"will be designed
to pickup off-site runoff from the area to the east. It is
proposed to install pipe to the property lines in two locations.
One pipe will provide for the developed runoff from the church
and one pipe will provide for the developed runoff from the
adjacent commercial property. All pipes are designed for the
runoff from the 100 year storm.
We hope this letter, coupled with the Preliminary Drainage Plan,
will answer all of your questions concerning site drainage. If
not, I will be happy to further explain this situation at the DRC
on Thursday, October 4, 1990.
If you have any questions please feel free to contact me.
Sincerely,
