**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.
