Dear Mayor Wolfe:
Case No.: 92-06-124P
Community: City of Coppell,
Texas
FIR~M Panel No.: 480170 0010 D
This letter is in response to a letter dated September 2, 1992, from
Mr~ Kenneth M~ Criffin, P.E., City Engineer, City of Coppell, regarding the
effective Flood Insurance Rate Map (FIRM) for the City of Coppell, Texas. In
his letter, Mr. Griffin requested that we revise the effective FIRM to show
the effects of fill placed along Tributary G-1 of Grapevine Creek, from
approximately 685 feet upstream of Bethel School Road to approximately
1,800 feet upstream of Bethel School Road.
All data required to support this request were submitted by Mr. Griffin with
his September 2 letter. This request documents final "as-built" conditions
for a development adjacent to Tributary G-1 of Grapevine Creek, for which a
conditional Letter of Map Revision (LOMR} was issued on November 19, 1991;
and it also revises the data used to prepare the preliminary FIRM panel
(only panel printed) for the City of Coppell, Texas, dated December 18, 1991.
We have completed our review of the data submitted, and have determined that
the technical report submitted in support of the request entitled "Floodplain
Analysis for a Final LOMR for a Portion of Tributary G-1 of Grapevine Creek,
City of Coppell, Dallas County, Texas," prepared by Goodwin and Marshall,
dated August 1992, represents the best available data for the above-described
reach of Tributary G-1 of Grapevine Creek.
Please note that this information will be included in the final printing of
the FIRM panel for the City of Coppell, Texas, presently scheduled for the
winter of 1992-1993. In the interim, until this data is included in the
final printing, the City of Coppell and the State of Texas may utilize these
data in their floodplain management programs.
If you have any questions regarding this matter, please call Mr. Alan Johnson
of my staff in Washington, D.C., at (202) 646-3403.
Sincerely,
