Title

Talbert Lake Diversion Project

Description

The proposed project is a Santa Ana Regional Water Quality Control Broad-approved Supplemental Environmental Project (SEP) involving the construction of a natural treatment system in the northeastern corner of Central Park in Huntington Beach, on the eastern side of Goldenwest Street. The proposed project would divert up to 3 million gallons per day (mgd) of dry weather flows from the East Garden Grove Wintersburg Channel (EGGWC) into a newly constructed treatment wetlands system for water quality improvement purposes. The constructed wetlands would be located in the northeastern corner of Central Park between Slater Avenue and Talbert Avenue to the north and south, and Goldenwest Street and Gothard Street to the west and east. Project components include the construction of a diversion structure such as a rubber dam within the EGGWC to divert dry weather flows either into an existing water line in Goldenwest Street, or the existing storm drain system within Gothard Street, for transport to the newly constructed treatment wetlands within Central Park. These treatment wetlands would consist of three linear wetland features encompassing open water and channel areas and channels through which diverted channel flows would move and be subjected to a series of natural treatment processes improving overall water quality. Project objectives include the improvement of water quality and the potential beneficial reuse of treated water on site for park irrigation purposes if sufficient water is available.
