Bear Creek Channel Diversion and Bank Stabilization
DeQueen, Arkansas
FTN prepared the design, plans and construction specifications, and construction cost estimates for a channel improvement project for Bear Creek in southwestern Arkansas. Bear Creek runs adjacent to the facility and is adjacent to a remediation area at the plant. The combined construction cost for the two phases of the project was approximately $550,000.
Design included:
Realignment of the channel;
Bank and channel stabilization; and
Lateral drainage connections.
FTN participated in the construction oversight for both phases of the project and obtained the appropriate regulatory approvals. Project tasks included:
Hydraulic modeling to determine impact of channel diversion on 100-year-water surface elevations;
Preparation and submittal of Section 404 permit application and supporting documentation;
Preparation and submittal of application and documentation for a FEMA Letter of Map Revision;
Design and preparation of drawings for 450-linear feet of cutoff channel with associated riprap bank and channel stabilization and end returns;
Design and preparation of drawings for a total of approximately 250- linear feet of gabion retaining wall/bank stabilization in two reaches with gabion mattress aprons and riprap end returns;
Preparation of Engineer’s Opinion of Probable Construction Costs;
