Project Info

Title
Twin Pines Stormwater Detention Basin Project
Description
The proposed Project involves the construction of an underground stormwater storage facility beneath the parking lots or other areas of the 10-acre Twin Pines Park. The project is designed to attenuate the peak stormwater flow of Belmont Creek, to trap sediment and debris, to reduce flood risk in the flood-prone lower creek reach, downstream of El Camino Real, and to provide ancillary water quality benefits. A diversion weir would divert high flows from Belmont Creek to the 9-acre-foot underground storage facility, where water would remain before flowing back into Belmont Creek through a 12-inch outlet pipe. The project would also include a sediment chamber, bank stabilization along Belmont Creek, and an in-stream check structure in Belmont Creek.
