TEI FILE NO. 3344
Dear Ms. Davis: k�1lD
By letter dated April 28, 1992, your office sent a data request
check list which identified additional items required for your
review of the Villages of Coppell - Phases III and IV request for
a conditional letter of map revision (LOMR).
Item 11 of the check list requested a general description of the
proposed hydraulic conditions, including channel modifications or
other projects on which the conditional revision request is based.

Denton Creek. The Northerly side of the site currently is within
a 100 -foot wide, shallow inundation, flood -fringe area. This area
is proposed to be filled to reclaim it from the 100 -year
floodplain. A gabion retaining wall will be constructed at the
property line to prevent the toe of fill from extending onto an
adjacent public road (Deforest Road). Denton Creek cross sections
18440, 19330 and 19930 reflect the proposed changes along this
Northerly property line (see exhibit "C" Sheet 1).
On the Easterly site of the property Denton Creek meanders along
the back of the lots off of Parker Drive (see Exhibit "B "). This
side of the creek is the high bank, generally confining the flow
within the main stream of the creek. The opposite bank is the low
bank which opens to a 6000 foot wide flood plain that is shared
with the Elm Fork of the Trinity River. Within this reach, the Elm

questions concerning this submittal, please call.
