This is in response to a letter dated April 10, 1992, from Mr. Kenneth
Griffin, P.E., City Engineer, City of Coppell, regarding a request for a
Conditional Letter of Map Revision (CLOMR) to the effective Flood Insurance
Rate Map (FIRM) for the City of Coppello Texas, dated October 16, 1991.
The CLOMR request represents a revision to the effective 100 -year floodplain
and effective floodway boundaries along Denton Creek and Elm Fork of Trinity
River. The request is based On proposed fill between Cross Sections 104880
and 105500 along Elm Fork of Tr4 pity River, and between -Cross Sections 1$440
and 19930 along Denton Creek. All of the data necessary to process this
request were received with a letter dated April 10, 1992, from Mr. Griffin; a
letter dated June 5, 1992, from Mr. Robert Porter, Project Manager, Tipton
Engineering, Inc.g and a letter dated June 30, 1992, from Mr. Richard Hovas,
P.E., Vice President, Tipton Engineering, Inc. Fees necessary to process
this CLOMR (a total of $1,410) have been received.
We have completed our review of the submitted data with regard to the data
used to produce an ongoing restudy of the Flood Insurance Study for the City
of Coppell, We believe Chat' a revision to the 100 -year floodplain and
f140dw6y would be warranted after the ongoing restudy becomes effective and
if the proposed project is constructed as shown on
"Exhibit B, Reclamation Plan, Villages of Cappelli Phases h 3 and n 4, City lof
Coppell, Texas," prepared by Don A. Tipton, Inc., dated January 1991, and as
described in the report entitled "Elm Fork Trinity River and Denton Creek,
City of Coppell, Dallas Country, Texas, Floodpl -ain Reclamation Study, Village$
Of Coppell, Phases 3 and 4, Request for Conditional LOMR," prepared by Don A.
Tipton, Inc. Floodplain and floodway boundaries would be revised according
to those shown on the same plan.
Upon completion of this project, please submit an "as- built" grading and site
plan, certified by a registered professional engineer, for the reclamation
area; certification that fill, placed in the currently effective floodplain as
a result of this . project is compacted to 95 percent of the maximum density
obtainable with the Standard Proctor Test method issued by the American
Society for Testing and Materials JASTM Standard D-
analysis for the proposed Gabion Wall along Deforest Road between Cross

Sections 18440 and 19930. We will make a final determination on revising the
FIRM upon receipt of the dater listed above.
Please note that the City of Cnppell is undergoing A citywide restudy and
that the study hAs been appealed. The appeal does not affect the
Denton Creek and Elm Fork of Trinity River associated wi.rh this project. IC
is anticipated that the restudy will become effective in 1993, Because this
request is based 'on flooding information contained in the restL!dy, $ final
map revision for this project: can only be processed after the restudy becomes
effective.
Please note that the Federal, Emergency Management Agency (FEMA) has developed
detailed application and certification forms for use in requesting revisions
or amendments to NFIP maps„ These forms will be used for all requests
received by FEMA on or after October 1, 1992. These forms highlight
technical considerations in a fashion that facilitates an eliiciE!nt review,,
therefore, use of these forms prior to October 1 is strongly recommended.
Applications are available for Letter of Map Amendment and Letter of Map
Revision Based on Fill requests. Application forms for all other revision
requests should be available after September 1.
