# SUMMARY:

The Albuquerque District, U.S. Army Corps of Engineers (Corps) has prepared a draft Supplemental Environmental Impact Statement (SEIS) on the findings of a flood risk management study along the Rio Grande from San Acacia downstream to San Marcial in Socorro County, New Mexico. The recommended plan is to replace the existing embankment between the Low Flow Conveyance Channel and the Rio Grande with a structurally competent levee capable of containing high-volume, long-duration flows. This engineered levee would substantially reduce the risk of damage from floods emanating from the Rio Grande. The local cost-sharing sponsors of the proposed project are the Middle Rio Grande Conservancy District and the New Mexico Interstate Stream Commission.

# SUPPLEMENTARY INFORMATION:

                    Previously, an environmental impact statement (1992) and a supplement (1977) were published regarding this project. Currently, a new draft SEIS has been prepared to evaluate effects of revised levee design and additional alternatives. The draft SEIS is integrated with a draft General Reevaluation Report, and the integrated document is entitled:                     *Draft General Reevaluation Report and Supplemental Environmental Impact Statement II: Rio Grande Floodway, San Acacia to Bosque del Apache Unit, Socorro County, New Mexico*                     (hereafter referred to as the draft GRR/SEIS-II).                

Alternatives developed and evaluated during the current and previous studies consist of levee reconstruction; flood and sediment control dams; local levees; intermittent levee replacement; watershed land treatment; floodproofing of buildings; levee-alignment setbacks; and no action. Issues analyzed in the development of the draft GRR/SEIS-II included the effect of alternatives on flood risk, developed lands and structures, water quality, ecological resources, endangered species, social welfare, cultural resources, and aesthetic qualities.

*Public Review:*                     The 45-day long review public review period for the                           ( print page 25152)                        draft SEIS begins on April 27, 2012; or on the filing date published by the U.S. Environmental Protection Agency in the                     **Federal Register**                    , if later. Copies of the draft SEIS are available at:                     *http://www.spa.usace.army.mil/​fonsi/​.*                     Copies also are available for review at the Socorro Public Library, 401 Park St, Socorro, NM.                

A public meeting will be held during the review period in Socorro, New Mexico. An announcement of the exact date and location of the public meeting will be published in the Socorro, Albuquerque, and Santa Fe newspapers.

U.S. Army Corps of Engineers Acting Chief, Planning Branch.
