Environmental Assessment Flood Damage Reduction Study. Design Change to Expand Levee Riverward at Two Locations, South Quincy Drainage and Levee District Adams County, Illinois

Abstract

The Army Corps of Engineers has proposed raising an existing levee located south of Quincy, IL between Mississippi River miles 318.5 to 325.5. The levee will be raised to provide additional protection from the 500-year frequency flood event for high quality agricultural lands and existing industrial and commercial activities. As planning and engineering investigations continued, requests were received to consider expanding the main stem levee base riverward at two locations, instead of landward as originally planned, to avoid discharging material into two permanent bodies of water located just landward of the levee. This environmental assessment addresses these additional design changes. Also included is a finding of no significant impact (FONSI), and a preliminary section 404 (b) (1) evaluation.
