Title

Pacoima Spreading Grounds Improvement Project

Description

Project involves improvements to existing facilities to increase water storage capacity from 530 af to 1,197 af; increase percolation rate from 65 cfs to 142 cfs; eliminate localize flooding; and improve efficiency of operations and maintenance. The improvements would include replacing the intake canal with underground pipeline; deepening and combining the basins to remove the underlying clay layer; and replacing interbasin and outlet structure. Approx 1.6 M cy of sediment would be excavated from the spreading basins; of this, approx 1.37 M cy would be exported to three gravel/sediment processing pits and one landfill. Sediment export would generate up to 239 round trips from 14-cy haul trucks or 186 round trips from 18-cy haul trucks per day, for approx 20 months beginning Fall 2019.
