Dear Mr. Ginn:
We have received your request dated September 23, 1987, with supporting
technical documentation for a Conditional Letter of Map Revision for Grape-
vine Creek in Coppell.
Your request has been provided to t.he appropriate engineering staff for com-
pletion of the technical evaluation portion of the review. You will be noti-
fied of any costs associated with the Conditional Letter of Map Revision.
I note that two projects are included in your request: a Proposed Bridge
Replacement at Denton Tap Road, and a proposed floodplain reclamation of
portions of an 18.4'acre tract owned by Elvis and Roland Andrews. You have
stipulated that the project developer will provide the necessary perpetual
maintenance of the altered floodway following completion of the project and
that procedures are in place for ensuring that the credited improvements are
not allowed to deterioriate.
It is imperative that the'City prohibit any placement of buildings or other
structures on any portion 6f the proposed reclaimed area until all channeliza-
tion or other activities on which the reclamation is based have been completed
and an official Final Letter of Map Revision issued b~ the Federal Emergency
Management Agency. The provisions for this restriction are addressed in
Section 60.2(h) of the National Flood Insurance Program Regulations:
"The community shall adopt and enforce floodplain management
regulations based on data provided by tae Administrator. With-
out prior approval of the Administrator, the community shall not
adopt and enforce floodplain management regulations based upon
modified'data reflecting natural or man-made physical changes."
This guidance is provided you in your capacity as City Engineer for the City of
