DEPARTMENT OF HOMELAND SECURITY

Federal Emergency Management Agency

44 CFR Part 67

[Docket No. FEMA-B-7781]

 
Proposed Flood Elevation Determinations

AGENCY: Federal Emergency Management Agency, DHS.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: Comments are requested on the proposed Base (1 percent annual-
chance) Flood Elevations (BFEs) and proposed BFE modifications for the 
communities listed in the table below. The purpose of this notice is to 
seek general information and comment regarding the proposed regulatory 
flood elevations for the reach described by the downstream and upstream 
locations in the table below. The BFEs and modified BFEs are a part of 
the floodplain management measures that the community is required 
either to adopt or show evidence of having in effect in order to 
qualify or remain qualified for participation in the National Flood 
Insurance Program (NFIP). In addition, these elevations, once 
finalized, will be used by insurance agents and others to calculate 
appropriate flood insurance premium rates for new buildings and the 
contents in those buildings.

DATES: Comments are to be submitted on or before August 14, 2008.

ADDRESSES: The corresponding preliminary Flood Insurance Rate Map 
(FIRM) for the proposed BFEs for each community are available for 
inspection at the community's map repository. The respective addresses 
are listed in the table below.
    You may submit comments, identified by Docket No. FEMA-B-7781, to 
William R. Blanton, Jr., Chief, Engineering Management Branch, 
Mitigation Directorate, Federal Emergency Management Agency, 500 C 
Street, SW., Washington, DC 20472, (202) 646-3151, or (e-mail) 
bill.blanton@dhs.gov.

FOR FURTHER INFORMATION CONTACT: William R. Blanton, Jr., Chief, 
Engineering Management Branch, Mitigation Directorate, Federal 
Emergency Management Agency, 500 C Street, SW., Washington, DC 20472, 
(202) 646-3151, or (e-mail) bill.blanton@dhs.gov.

SUPPLEMENTARY INFORMATION: The Federal Emergency Management Agency 
(FEMA) proposes to make determinations of BFEs and modified BFEs for 
each community listed below, in accordance with section 110 of the 
Flood Disaster Protection Act of 1973, 42 U.S.C. 4104, and 44 CFR 
67.4(a).
    These proposed BFEs and modified BFEs, together with the floodplain 
management criteria required by 44 CFR 60.3, are the minimum that are 
required. They should not be construed to mean that 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 of its own, or pursuant to policies established 
by other Federal, State, or regional entities. These proposed 
elevations are used to meet the floodplain management requirements of 
the NFIP and are also used to calculate the appropriate flood insurance 
premium rates for new buildings built after these elevations are made 
final, and for the contents in these buildings.
    Comments on any aspect of the Flood Insurance Study and FIRM, other 
than the proposed BFEs, will be considered. A letter acknowledging 
receipt of any comments will not be sent.
    Administrative Procedure Act Statement. This matter is not a 
rulemaking governed by the Administrative Procedure Act (APA), 5 U.S.C. 
553. FEMA publishes flood elevation determinations for notice and 
comment; however, they are governed by the Flood Disaster Protection 
Act of 1973, 42 U.S.C. 4105, and the National Flood Insurance Act of 
1968, 42 U.S.C.

4001 et seq., and do not fall under the APA.
    National Environmental Policy Act. This proposed rule is 
categorically excluded from the requirements of 44 CFR part 10, 
Environmental Consideration. An environmental impact assessment has not 
been prepared.
    Regulatory Flexibility Act. As flood elevation determinations are 
not within the scope of the Regulatory Flexibility Act, 5 U.S.C. 601-
612, a regulatory flexibility analysis is not required.
    Executive Order 12866, Regulatory Planning and Review. This 
proposed rule is not a significant regulatory action under the criteria 
of section 3(f) of Executive Order 12866, as amended.
    Executive Order 13132, Federalism. This proposed rule involves no 
policies that have federalism implications under Executive Order 13132.
    Executive Order 12988, Civil Justice Reform. This proposed rule 
meets the applicable standards of Executive Order 12988.
