RE: JP No. 88009; Flood Plain Analysis;
Parks of Coppell; Coppell, Texas
Dear Carl:
Pursuant to our telephone conversations of yesterday and today,
please prepare for our use the following information regarding
your hydraulic modelling of Denton Creek and Cottonwood Branch
developed for the City of Coppell.
1. Hydraulic model and output data of the existing watershed
and stream conditions of Denton Creek and Cottonwood Branch
for all frequency floods you have analyzed. The models
should cover Denton Creek from the confluence with
Cottonwood Branch upstream to Grapevine Lake Dam and
Cottonwood Branch from the confluence with Denton Creek
upstream to Bethel Road.
2. Copies of maps showing stream cross section locations within
the previously described reaches. Also please indicate a
reference station on each cross section on Denton Creek
between the Cottonwood Branch confluence and Coppell Road
and on each cross section on Cottonwood Branch between
Denton Tap Road and Coppell Road.
3. Any floodway analysis you prepared in the previously
described reaches of each stream.
4. Maps showing limits of the 100-year and 500-year flood
plains and the 100-year floodway, if available, within the
previously described reaches of each stream.
Please do not prepare any new information pursuant to this
request. We are interested in obtaining copies of information
listed above as it is currently available. I would appreciate
paper copies of all input and output hydraulic models and maps as
well as copies of the computer models on floppy diskettes.

Please provide additional information in excess of that listed
above if doing so will require less effort than trying to
minimize the information prepared to only that requested. Also
please advise me in advance if your fee for services under this
request will exceed $300.00.
Thank you for your prompt attention to this matter. I will come
by your office on Wednesday, June 22, 1988 at 2:00 P.M. to pick
up this information and review it with you.
Sincerel~
