Project Info

Title

Final EIR Randall Road Debris Basin

Description

The project consists of a debris basin to be constructed on parcels where the residences were destroyed during debris flows on January 9, 2018. The design of the project provides an 8 acre area for deposition of large sediment loads and woody debris during/following larger storm events while maintaining natural sediment transport during smaller storm events. The debris basin would only receive flows and material (sediment and debris) once the designed channel capacity has been exceeded which correlates to the water surface elevation generated in a 5-year flow event. The project Includes post-construction restoration of the berm along East Valley Road, areas along the creek and the basin slopes.
