Moccasin Bend Stream Bank Stabilization
Hamilton County, Tennessee
On February 22, 2010, TVA issued a finding of no significant impact (FONSI) on a proposal submitted by the National Park Service (NPS) to stabilize a 5.9-mile section of the Tennessee River bank within the Moccasin Bend National Archaeological District (MBNAD) in Chattanooga, Hamilton County, Tennessee. This action requires approval by TVA under Section 26a of the TVA Act. The MBNAD is one of the most significant archaeological sites in the Southeast and is a National Historic Landmark. This portion of the river has experienced bank erosion and sloughing, which is jeopardizing the integrity of cultural resources. NPS proposes to stabilize six reaches of the right-descending riverbank between Tennessee River miles 457.2 and 463.1. The stabilization would be done with a combination of techniques, including full riprap protection, partial riprap protection, and bioengineering. In addition to protecting archaeological sites, the stabilization would improve water quality, aquatic and terrestrial wildlife habitat, and visual resources. TVA adopted a final environmental assessment (EA) prepared by the U.S Army Corps of Engineers (USACE) that evaluated the potential impacts of the bank stabilization project. TVA’s FONSI is presented below. The USACE EA and the NPS FONSI are available upon request.
