Document Description
The proposed project consists of drainage improvements along Aliso Canyon Road beginning at the intersection of Aliso Canyon Road and El Camino del Norte and extending north on Aliso Canyon Road to the T-intersection with Avendia del Duque. Drainage improvements include replacing and improving existing underground storm drain pipes, culvert, curb inlets, catch basins, headwalls, storm drain cleanouts, and associated utility relocations and roadway improvements. The total length of the project is ~2,100 ft. The purpose of the project site is to allow proper conveyance of storm flows, up to the 100 yr storm, as the current stormdrain is undersized resulting in flooding of Aliso Canyon Road during large storm events. Project elements include replacement of existing corrugated metal pipes (CMP) with reinforce concrete pipes (RCP) and reinforced concrete boxes (RCB), a transition structure, cleanouts, headwalls, wingwalls, curb inlets and road improvements associated with installation of the new pipes. The existing storm drain is within County right-of-way; however, additional drainage easements will be obtained as part of the project.
