Dear Mr. Kuno=

W&A %83-096~ COTTONWOOD BRANCH
Coppe11, Texas
Our firm is currently preparing construction plans for
improvements along Cottonwood Branch within the City of Coppe11,
Texas. The improvements for the proposed subdivision will
include reclaiming the flood fringe by filling. In accordance
with your instructions in conversations with Mr. Rea
Stevenson, P.E. of our staff and by'letter dated February 26,
1985, please find enclosed our hydraulic analysis of Cottonwood
Branch.
Three (3) copies of the following items are contained in our
submittal.
1. A copy of the recorded deed for the property.
Topographic map of the tract showing the existing 100
year and 500 year flood boundaries, the limits of the
floodway and the toe of the slope of the proposed fill.
A copy of the Flood Boundary and Floodway Map of Coppell,
Texas, showing the location of the subject tract.
A copy of the HEC-2 computer run of the natural condition

6. A-Letter of Approval for the proposed project from the
City of Coppe11, Texas.
Our HEC:2 analysis was developed by combining the original
HEC-2 run on the creek done by the Corps of Engineers in 1978
vith the revision of the lo-er reach done by a consultant which
was completed in 1982. The 1982 revision of the Corps' HEC-2
run ended downstream of this property, so it was necessary for
us to combine the two runs in order to determine the revision's
affect on our tract. We inserted a field-surveyed section
between Sections B and C, shown as Section BB on our exhibit, in
order to more clearly define the profile of the creek.
We are proposing to reclaim a small section of the flood
fringe on Denton Creek which lies within this property. This
area has also been shown on our exhibit.
We respectfully request that FENA review our hydraulic
analysis and provide us a Letter of Belief stating that the
agency has no opposition to the proposed project. Upon comple-
tion of the construction of the improvements, we will request a
Letter of Nap Revis£on so that the filled area can be removed
from the flood fringe shown on the FIRM Nap.
We would appreciate your prompt attention to this matter.
If you should have any questions or desire additional informa-
tion, please do not hesitate to call on me.
Sincerely,
DAVID B. NcCARVER, P.E.
