Department of the Army, Corps of Engineers March 2, 2012 – Federal Register Recent Federal Regulation Documents

The Albuquerque District, Corps of Engineers (Corps) is preparing a draft Supplemental Environmental Impact Statement (SEIS) on the findings of an ongoing flood risk management study along the Rio Grande from San Acacia downstream to San Marcial in Socorro County, New Mexico. The purpose of the study is to reevaluate the plan of flood protection authorized by the Flood Control Act of 1948 (Pub. L. 80-858) in light of recent changes in levee design parameters and environmental resources in the study area. The tentatively proposed 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.
