STORM WATER DETENTION FACILITY
The detention dam facility mitigates the increased runoff from the 250+ acre Singing Hills mixed-use development.
PROJECT DETAILS
- ~10 acres of storage area for rainfall events
- The detention pond has a storage volume of 46 acre-feet. The discharge rate out of the pond for the 100 year storm event is 778 CFS
- Controlled discharge of stormwater to pre-existing natural creek
- The pond reduces the existing Q100 flowrate at the US 281 and SH 46 intersection by approximately 10%. The pond was designed to reduce the discharge rate by approximately 40% better than the regulated design requirement.
- Includes installation of new swing gates and reinforced fencing as well as a concrete spillway with baffle blocks and rock gabion mattresses for discharge control
