21st Street Ditch Project

21st Street Ditch Project

The 0.22-acre project site includes a 203-foot segment of an unnamed, unlined drainage ditch that is approximately 5 feet in diameter. Water flows from west to east through the ditch; flows are intermittent/ perennial and are typically from urban runoff and storm events. The proposed project would permanently place a 36-inch solid storm drain pipe (connecting at both culvert outlets) and fill materials within the 203-foot portion of the unnamed drainage feature. The proposed project would also involve rehabilitation grading of the existing drainage channel to approximately match the existing surface elevations of the street and tennis facility located south of 21st Street. The purpose of the proposed project is to improve floodwater conveyance, maintain flow rate efficiency, and remove localized nuisance water.
