Proposed Flood Elevation Determinations
AGENCY: Federal Emergency Management Agency
ACTION: Proposed rule.
SUMMARY:
Technical information or comments are solicited on the proposed modified
base (100 -year) flood elevations shown on your community's preliminary Revised
Flood Insurance Rate Map (FIRM). These base (100 -year) flood elevations are
the basis for the floodplain management measures that the community is
required to either adopt or show evidence of being already in effect in order
to qualify or remain qualified for participation in the National Flood
Insurance Program (NFIP). The proposed base flood elevations modify the base
flood elevations shown on your community's presently effective FIRM.
DATES:
The period for comment will be ninety (90) days following the second
publication of this proposed rule in a newspaper of local circulation in the
community.
ADDRESSES:
Preliminary FIRMs showing the proposed modified base flood elevations
and their delineation are available for review at the Coppell City Hall, 255
Parkway, Coppell, Texas.
Send comments to:
The Honorable Alan D. Ratliff
Mayor of the City of Coppell

SUPPLEMENTARY INFORMATION:
The Federal Emergency Management Agency gives notice of the proposed
determinations of modified base (100 -year) flood elevations, in accordance
with Section 110 of the Flood Disaster Protection Act of 1973 (Pub. L. 93-
234), 87 Stat. 980, which added Section 1363 to the National Flood Insurance
Act of 1968 (Title XIII of the Housing and Urban Development Act of 1968 (Pub.
L. 90- 448)), 42 U.S.C. 4001 -4128, and 44 CFR 67.4(a).
These elevations, together with the floodplain management measures
required by Section 60.3 of the program regulations, are the minimum that are
required. They should not be construed to mean the community must change any
existing ordinances that are more stringent in their floodplain management
requirements. The community may at any time enact stricter requirements on
its own, or pursuant to policies established by other Federal, State, or
regional entities. These proposed elevations will also be used to calculate
the appropriate flood insurance premium rates for new buildings and their
contents and for the second layer of insurance on existing buildings and their
contents.

Pursuant to the provisions of 5 USC 605(b), the Administrator, to whom
authority has been delegated by the Director, Federal Emergency Management
Agency, hereby certifies that the proposed flood elevation determinations, if
promulgated, will not have a significant economic impact on a substantial
number of small entities. A flood elevation determination under Section 1363
forms the basis for new local ordinances, which, if adopted by a local
community, will govern future construction within the floodplain area. The
elevation determinations, however, impose no restriction unless and until the
local community voluntarily adopts floodplain ordinances in accord with these
elevations. Even if ordinances are adopted in compliance with Federal
standards, the elevations prescribe how high to build in the floodplain and do
not proscribe development. Thus, this action only forms the basis for future
local actions. It imposes no new requirement; of itself it has no economic
impact.
Proposed base flood elevations along flood sources studied in detail are
shown on the Preliminary FIRM. Lessees and owners of real property in the
City of Coppell, Dallas and Denton Counties, Texas, are encouraged to review
