Abstract: The Fourche Bayou Basin project was authorized by Section 401a of the Water Resources Development Act of 1986 for flood control and allied purposes to include channelization and the acquisition of 1,750 acres of Fourche bottomland hardwoods with nature appreciation facilities for environmental preservation and recreation. The Assistant Secretary of the Army for Civil Works made a Record of Decision dated 31 May 1983, which excluded the 1,750-acre Fourche Bottoms acquisition with the nature appreciation facilities from Federal participation as these lands were not necessary for the flood damage reduction project to function properly. The flood control portion of the project was constructed. In April 2000 after requests from the city of Little Rock, the ASA(CW) stated that a limited reevaluation report would be prepared to decide whether to budget for the unconstructed work: the 1,750-acre acquisition with nature appreciation facilities. The reevaluation found that the bottomland acquisition for environmental protection and flood reduction with nature appreciation facilities is consistent with policy. The recreation facilities include 3 miles of trails and boardwalks, bridges, restrooms, signage, parking, and an access road. The recreation features have a benefit to cost ratio of 1.8. An incremental analysis of the bottomland acquisition found that acquiring the entire 1,750 acres would result in the greatest increase to the wetland values and functions with an incremental cost per output of $2,337. The work is estimated to cost a total of $5,185,000. The 1,750-acre acquisition is estimated to cost $2,650,000, the LRR is estimated to cost $520,000, and the nature appreciation facilities are estimated to cost $2,015,000. The sponsor is the city of Little Rock, which is responsible for cost sharing and the operation and maintenance after construction. It’s share of costs are estimated to be $1,180,000 or $2,117,000 depending on whether the cost sharing percentage required is 25 or 35 percent for the environmental protection measure. Likewise, the Federal share is estimated to be $3,385,000 or $3,068,000 at 75 or 65 percent. The costs are within the increases allowed by Section 902 on the maximum cost of a project. No additional Congressional authorization is required and the LRR is within the Division Commander’s authority to approve. The proposed action would have no significant detrimental impact upon the human or natural environment. If the project is funded, a Record of Decision will be prepared for either the Southwestern Division Commander or the Assistant Secretary of the Army for Civil Works to sign.
