Document Description
The existing 24-inch diameter storm drain outfall pipe will be replaced with a 48-inch diameter HDPE pipe. The storm drain pipe within Pastori Avenue was replaced with a 48-inch diameter pipe in 2008. Air-driven jack hammers will be used to break the wall for the storm drain pipe. There will be no hydraulic equipment. A stable engineered RSP Energy Dissipation Structure with Large Woody Debris Channel Margin will be installed. The triangle-shaped apron area beneath the culvert outfall will be lined with 1-2 ton mixed rock riprap, up to an elevation to protect the immediately downstream site that is currently covered with lighter weight emergency rock rip rap. Large woody debris (one rootwad with trunk) will be installed in the base of the rock rip rap at the margin of the pool.
