Document Description
The City owns the right to divert up to 25 cubic feet per second (cfs) of surface water from the Arroyo Seco for direct use or for spreading into their basins for groundwater pumping credits in the Raymond Basin. The City receives between 60 to 80% pumping credit for the amount of water recharged into the Basin. The Project involves water infrastructure improvements in the Arroyo Seco Canyon to allow for the diversion and spreading of up to 25 cfs of surface water. Improvements in Area 2 . involve the demolition and replacement of an existing diversion/weir and intake structure in the same general location. Improvements in Area 3 involve the reconfiguration and expansion of existing spreading basins. The Project objective is to increase the beneficial use of the City's surface water rights and to improve biological functions within the Arroyo Seco.
