Dear Mayor Wolfe:

Case Nos.: 6 -89 -236 and 6 -90 -152
Community: City of Coppell,

Counties, Texas
Community No.: 480170
This is in further reference to the ongoing revision request to the Flood
Insurance Study (FIS) and Flood Insurance Rate Map (FIRM) for the City of
Coppell currently being processed by the Federal Emergency Management Agency.
In our November 30, 1990 letter to you concerning this request, we listed
several review concerns that needed to be resolved and additional items that
need to be submitted before this revision can be processed. This letter
further stated that if the requested information were not received within 30
days, the September 22, 1988 preliminary FIRM would be finalized. The
requested items were received in early January 1991. While the data we
received answered some of the concerns, we found that the submitted work maps
for this revision were missing delineations of portions of the 100 -year
floodplain, 500 -year floodplain, and /or FEMA- designated floodway representing
existing conditions at numerous locations, rendering them insufficient to
revise the preliminary FIRM.
Therefore, because of the lack of supporting data for this revision and the
fact that the September 22, 1988 preliminary FIRM reflects increased flood
hazards over the effective February 15, 1984 FIRM, we will shortly be issuing
a letter of final determination and publishing the September 22, 1988 pre-
liminary FIRM in its final effective form.
When work maps are submitted with complete revised floodplain and floodway
delineations, we will initiate a separate revision to the FIS and FIRM for
Coppell to reflect this information. Please submit these revised floodplain
work maps directly to our Technical Evaluation Contractor, Dewberry & Davis,
8401 Arlington Boulevard, Fairfax, Virginia 22031, to the attention of
Mr. Joseph Chapman, Management Engineering and Technical Services Division.
These maps should contain complete 100- and 500 -year floodplain and floodway
delineations for all streams based on the submitted existing conditions models
prepared by Kimley -Horn Associates. Our processing of the revision will be
considered inactive pending receipt of the revised floodplain work maps.
