Florin Creek Multi-Use Basin Project (Lake or Streambed Alteration Agreement No. 1600-2014-0168-R2.)

Florin Creek Multi-Use Basin Project (Lake or Streambed Alteration Agreement No. 1600-2014-0168-R2.)

The California Department of Fish and Wildlife (CDFW) has executed Lake and Streambed Alteration Agreement number 1600-2014-0168-R2, pursuant to section 1602 of the Fish and Game Code to the project Applicant, SAFCA. The project proposes to construct two multi-use detention basins to provide flood control for areas within the 100-year floodplain of Florin Creek and recreational benefits for the community. The project would store up to 32.5 acre-feet of Florin Creek flows and would provide at least 100-year flood protection to structures within the City and County of Sacramento in the vicinity and downstream of the project site by reducing flood risk. The basins would be up to eight feet deep and would be constructed with typical side slopes of 5:1. A weir would be constructed on the north bank of Florin Creek at Florin Creek Park to allow floodwaters to spill into the park at storm events exceeding a 25-year event, into the ponds and the southern basin. As flood events increase water surface elevations, water would flow over the weir into the southern basin then incrementally flow through the interconnecting 48-inch culvert to the second basin to the north until the capacity at both is reached in a 100-year flood event. As high flood flows in Florin Creek subside, detained water would flow back into Florin Creek either over the weir or through a 36-inch culvert located on the southwestern end of the park. A flap gate on the creek end of the culvert would prevent water in the creek from entering the basin.
