44 CFR Part 67

 
Final Flood Elevation Determinations

AGENCY: Federal Emergency Management Agency, DHS.

ACTION: Final rule.

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

SUMMARY: Base (1% annual chance) Flood Elevations (BFEs) and modified 
BFEs are made final for the communities listed below. The BFEs and 
modified BFEs are the basis for the floodplain management measures that 
each community is required either to adopt or to show evidence of being 
already in effect in order to qualify or remain qualified for 
participation in the National Flood Insurance Program (NFIP).

DATES: The date of issuance of the Flood Insurance Rate Map (FIRM) 
showing BFEs and modified BFEs for each community may be obtained by 
contacting the office where maps are available for inspection as 
indicated on the table below.

ADDRESSES: The final BFEs for Imperial County are available for 
inspection at Imperial County Planning & Development Services 
Department, 801 West Main Street, El Centro, California 92243.

FOR FURTHER INFORMATION CONTACT: William R. Blanton, Jr., Engineering 
Management Branch, Mitigation Directorate, Federal Emergency Management 
Agency, 500 C Street SW., Washington, DC 20472, (202) 646-3151.

SUPPLEMENTARY INFORMATION: The Federal Emergency Management Agency 
(FEMA) makes the final determinations listed below for the modified 
BFEs for each community listed. These modified elevations have been 
published in newspapers of local circulation and ninety (90) days have 
elapsed since that publication. In proposed rule FR Doc. E7-18260 
published on March 27, 2006 (71 FR 15115-15116), several modified 
elevations were not depicted as being located below sea level. The 
symbology for these elevations has been corrected and is shown in the 
table below. The Assistant Administrator of the Mitigation Directorate 
has resolved any appeals resulting from this notification.
    This final rule is issued in accordance with section 110 of the 
Flood Disaster Protection Act of 1973, 42 U.S.C. 4104, and 44 CFR part 
67. FEMA has developed criteria for floodplain management in floodprone 
areas in accordance with 44 CFR part 60.
    Interested lessees and owners of real property are encouraged to 
review the proof Flood Insurance Study and FIRM available at the 
address cited below for each community. The BFEs and modified BFEs are 
made final in the communities listed below. Elevations at selected 
locations in each community are shown.
    National Environmental Policy Act. This final 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.
    Regulatory Classification. This final rule is not a significant 
regulatory action under the criteria of section 3(f) of Executive Order 
12866 of September 30, 1993, Regulatory Planning and Review, 58 FR 
51735.
    Executive Order 13132, Federalism. This final rule involves no 
policies that have federalism implications under Executive Order 13132.
