SUMMARY:

On September 15, 2009, 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 74 FR 47169. The table provided here represents the flooding sources, location of referenced elevations, effective and modified elevations, and communities affected for Lawrence County, South Dakota, and Incorporated Areas. Specifically, it addresses the following flooding sources: Hungry Hollow Gulch, Ice House Creek, Ice House Creek Tributary A, Riggs Gulch, Spearfish Creek, and Unnamed Tributary to Higgins Gulch.

DATES:

Comments are to be submitted on or before June 6, 2011.

ADDRESSES:

You may submit comments, identified by Docket No. FEMA-B-1069, to Luis Rodriguez, Chief, Engineering Management Branch, Federal Insurance and Mitigation Administration, Federal Emergency Management Agency, 500 C Street, SW., Washington, DC 20472, (202) 646-4064 or (e-mail) luis.rodriguez1@dhs.gov.

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 74 FR 47169, in the September 15, 2009, issue of the Federal Register, FEMA published a table under the authority of 44 CFR 67.4. The table, entitled “Lawrence County, South Dakota, and Incorporated Areas” addressed the following flooding sources: Hungry Hollow Gulch, Ice House Creek, Ice House Creek Tributary A, Riggs Gulch, Spearfish Creek, and Unnamed Tributary to Higgins Gulch. That table contained inaccurate information as to the location of referenced elevation, effective and modified elevation in feet, or communities affected for these flooding sources. It also incorrectly listed the City of Deadwood as an affected community for Ice House Creek Tributary A; the affected community should have been listed as the City of Spearfish. 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.
