2011-19545. Proposed Flood Elevation Determinations

AGENCY:

Federal Emergency Management Agency, DHS.

ACTION:

Proposed rule; correction.

SUMMARY:

On May 25, 2010, FEMA published in the Federal Register a proposed rule that contained an erroneous table. This notice provides corrections to that table, to be used in lieu of the information published at 75 FR 29290. The table provided here represents the flooding sources, location of referenced elevations, effective and modified elevations, and communities affected for Anne Arundel County, Maryland, and Incorporated Areas. Specifically, it addresses the following flooding sources: Cabin Branch, Franklin Branch, Hall Creek, Little Patuxent River, Marley Creek, Midway Branch, Patapsco River, Patuxent River, Sawmill Creek, and Severn Run.

DATES:

Comments are to be submitted on or before November 1, 2011.

ADDRESSES:

You may submit comments, identified by Docket No. FEMA-B-1101, 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 (e-mail) [e-mail].

FOR FURTHER INFORMATION CONTACT:

Luis Rodriguez, Chief, Engineering Management Branch, Federal Insurance and Mitigation Administration, Federal Emergency Management Agency, 500 C Street SW., Washington, DC 20472, [phone] or (e-mail) [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.

Corrections

In the proposed rule published at 75 FR 29290, in the May 25, 2010, issue of the Federal Register, FEMA published a table under the authority of 44 CFR 67.4. The table, entitled “Anne Arundel County, Maryland, and Incorporated Areas” addressed the following flooding sources: Cabin Branch, Franklin Branch, Little Patuxent River, Marley Creek, Midway Branch, Patapsco River, Patuxent River, Sawmill Creek, and Severn Run. That table contained inaccurate information as to the location of referenced elevation, effective and modified elevation in feet, and/or communities affected for those flooding sources. In addition, it did not include the flooding source Hall Creek. In this notice, FEMA is publishing a table containing the accurate information, to address these prior errors. The information provided below should be used in lieu of that previously published.
