The basic purpose of this project, as determined by the Corps, is levee improvements and bank stabilization. The overall purpose of this project is to bring the existing Carver Levee up to current Federal Emergency Management Agency (FEMA) certification levels, protect the Minnesota Riverbank, protect city infrastructure, and protect the historic district.
Construction is anticipated to vary widely across the project limits. The applicant requests authorization to temporary impact to Spring Creek is 425-lf (0.19-ac) for the realignment and concrete lining of the channel. Impacts to Tributary 2 total 40-lf (0.02-ac) of permanent impact and 20-lf (0.01-ac) of temporary impact. These impacts are due to levee grading and utility replacement. Permanent impact to wetlands along the levee totals 0.43-ac. These impacts are due to the levee grading, flattening slopes and shifting the levee riverward to accommodate 15-ft clear zones along the landside of the levee. Temporary impact to wetlands along the levee total 0.46- ac. These impacts are due to disturbances from tree clearing and utility relocations. The proposed total permanent impact to the Minnesota River totals 669-lf (1.14-ac). These impacts are due to levee grading, riprap, and bendway weirs. The proposed temporary impacts to the river total 70-lf (0.13-ac) due to equipment access.
