Abstract: This Detailed Project Report and Environmental Assessment (DPR/EA) present the findings of the Section 14 Chickasaw Park Emergency Streambank Stabilization Project in Louisville, Kentucky. This report, prepared by the Louisville District, U.S. Army Corps of Engineers (USACE), documents the feasibility phase, including the plan formulation process, as well as potential environmental effects associated with the implementation of the recommended shoreline protection measures. This study is authorized under CAP, Section 14 of the 1946 Flood Control Act, as amended. The focus of this study is on approximately 250 linear feet of significantly eroded Chickasaw Park shoreline in West Louisville. First commissioned in 1923, Chickasaw Park was designed by the Olmsted Firm and is eligible for the National Register of Historic Places under Criterion A, B and C. Active erosion is threatening the northern section of the park near a picnic area and an internal one-way loop park road. The overall goal of this project is to protect the northern section of the park from the Ohio River derived erosional forces. The Non-Federal Sponsor (NFS) for this feasibility study is Louisville Metro Government, with the Department of Parks and Recreation as the point of contact. This DPR/EA summarizes baseline existing conditions in the study area, formulates, evaluates, and compares various shoreline protection measures and alternatives, and considers any anticipated environmental impacts of the final array of alternatives and the Recommended Plan. This report identified, evaluated, and recommends 250 feet of streambank protection consisting of geotextile/geogrid filter with riprap buttress. This alternative best meets the planning objectives of streambank protection within the study area and is aligned with the goals of the NFS. The fully funded project cost for design and implementation of the Recommended Plan is $6,213,000. Design and construction costs (if the project is implemented) will be shared with the NFS. Louisville Metro Parks and Recreation would therefore be obligated to contribute 35 percent of the costs for design and construction. The NFS must also pay for 100 percent of the cost of any operation and maintenance requirement after construction. The total federal cost share is estimated to be $4,038,450. All costs are at fiscal year (FY) 2023 price levels. The Recommended Plan provides streambank protection over a projected 50-year lifespan. Under the Section 14 Authority, the least-cost alternative plan is considered justified if the total cost of the proposed alternative is less than the cost to relocate the threatened facility or resource. The quantitative analysis performed to estimate the value lost if the park is closed and relocated is $8,664,000.
