REQUESTED ALTERATION: The proposed action consists of the construction of two drainage pump stations. Each pump station shall be comprised of a retention pond, electrical and mechanical buildings, and discharge pipes that are to be installed under LA Highway 628 and over the existing upper guide levee of the Bonnet Carré Spillway. Concrete scour pads are to be installed on the discharge side of the levee. One proposed station would have a nominal capacity of 267 cubic feet per second (CFS) capacity (Montz Pump Station #1). The second station would have a nominal capacity of 340 CFS capacity (Montz Pump Station #2). This proposed project is necessary to provide improved drainage capacity to the area. The USACE evaluation would also include all required Real Estate Actions for USACE owned properties in the vicinity of the proposed action.
Montz Pump Station #1 would be located approximately 1.3 miles north of the spillway control structure, just north of the Canadian National Railroad tracks. The pump station would include a 1.14 acre detention pond, a concrete intake and sump structure with sheet pile wing walls, four submersible mixed flow drainage pumps, a sheet pile cutoff wall, 36” diameter steel discharge piping, an electrical building, a diesel generator, a Supervisory Control and Data Acquisition (SCADA) tower, electrical and water service, asphalt pavement patching, a crossing on the crown of the guide levee, a concrete scour pad at the discharge, and security fencing.
Montz Pump Station #2 would be located approximately 2.3 miles north of the spillway control structure, just north of the Kansas City Southern Railroad tracks. The pump station would include a 1.03 acre detention pond, a concrete intake and sump structure with sheet pile wing walls, five submersible mixed flow drainage pumps, a sheet pile cutoff wall braced by steel plumb and batter piles, 36” diameter steel discharge piping, an electrical building, a diesel generator, a SCADA tower, electrical and water service, asphalt pavement patching, a crossing on the crown of the guide levee, a concrete scour pad at the discharge, and security fencing.
Both pump stations would be constructed, operated, and maintained by St. Charles Parish.
