Document Description
The Twin Creek Orange Show Road Storm Drain project is located in the City of San Bernardino, County of San Bernardino, CA. The City operates the drainage system infrastructure within its boundaries. The Twin Creek Orange Show Road storm drain system was originally constructed in 2002. The existing system is 36" reinforced concrete pipe (RCP) which discharges 92 cubic feet per second (cfs) into Twin Creek, although it is unclear what storm event this flow rate represents. The upstream end of the existing 36-inch drain line is just east of the railroad crossing near Amos Avenue, approximately 1,100 feet east of the Twin Creek channel.
