2012-27116. Proposed Flood Elevation Determinations

AGENCY:

Federal Emergency Management Agency, DHS.

ACTION:

Proposed rule; correction.

SUMMARY:

On January 24, 2008, September 27, 2010, and August 3, 2011, FEMA published proposed rules in the Federal Register. The August 3, 2011 proposed rule contained an erroneous table. This notice provides corrections to that table and combines all three notices to be used in lieu of the information published at 73 FR 4144, 75 FR 59192 and 76 FR 46705. The table provided here represents the flooding sources, location of referenced elevations, effective and modified elevations, and communities affected for Lafayette Parish, Louisiana, and Incorporated Areas. Specifically, it addresses the following flooding sources: Acadiana Coulee, Anselm Coulee, Bayou Carencro, Bayou Parc Perdue, Bayou Queue De Tortue, Beau Basin Coulee, Broadmoor Coulee, Coulee Des Poches, Coulee Fortune North, Coulee Fortune South, Coulee Ile Des Cannes, Coulee Ile Des Cannes—Lateral 1, Coulee Ile Des Cannes—Lateral 2, Coulee Ile Des Cannes—Lateral 3, Coulee Ile Des Cannes—Lateral 4, Coulee Lantier, Coulee LaSalle, Coulee Mine, Dan Dabaillion Coulee, Darby Coulee, Edith Coulee, Grand Avenue Coulee, Isaac Verot Coulee, Isaac Verot Coulee—Lateral 2, Isaac Verot Coulee—Lateral 2A, Isaac Verot Coulee—Lateral 3, Jupiter Street Coulee, Manor Park Coulee, Point Brule Coulee, Vermillion River, Webb Coulee (Lower Reach), and West Coulee Mine.

DATES:

Comments are to be submitted on or before February 5, 2013.

ADDRESSES:

You may submit comments, identified by Docket Nos. FEMA-B-7759, FEMA-B-1138 and FEMA-B-1208, to Luis Rodriguez, Chief, Engineering Management Branch, Federal Insurance and Mitigation Administration, Federal Emergency Management Agency, 500 C Street SW., Washington, DC 20472, [phone] or (email) [e-mail].

SUPPLEMENTARY INFORMATION:

The Federal Emergency Management Agency (FEMA) publishes proposed determinations of Base (1% annual-chance) Flood Elevations (BFEs) and modified BFEs for communities participating in the National Flood Insurance Program (NFIP), 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 minimum requirements. 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 also are used to calculate the appropriate flood insurance premium rates for new buildings built after these elevations are made final, and for the contents in those buildings.

Correction

In the proposed rule published 76 FR 46705, in the August 3, 2011 issue of the Federal Register, FEMA published a table under the authority of 44 CFR 67.4. The table entitled “Lafayette Parish, Louisiana, and Incorporated Areas” addressed the flooding sources Anselm Coulee, Coulee Des Poches, Coulee LaSalle, Coulee Mine, Isaac Verot Coulee, Isaac Verot Coulee—Lateral 2, Vermillion River, and Webb Coulee Lower Reach. The table contained inaccurate information as to the location of referenced elevation and effective and modified elevation in feet. In addition, it did not include several affected communities.

In this notice, FEMA is publishing a table containing the accurate information, to address these errors. The information provided below should be used in lieu of the previously published notices for Lafayette Parish, Louisiana, and Incorporated Areas that are referenced in the summary.
