Challenges in Planning and Design of Drainage Facilities for the Orange County Toll Roads

by Chenchayya T. Bathala, Parsons Brinckerhoff Quade &, Douglas Inc, Orange, United States,



Document Type: Proceeding Paper

Part of: Water Resources Planning and Management and Urban Water Resources

Abstract:

The Orange County Toll Roads project is a program which includes three modern, high-capacity, limited access highways; the Foothill, San Joaquin Hills and Eastern Transportation Corridors. These Corridors extending over 65 miles will have flexibility built in for future improvements such as high occupancy vehicles or transit. After completion, the California Department of Transportation (Caltrans) will take over the operation and maintenance of the roads. All the off-site and on-site drainage facilities must be designed based on Caltrans standards. The off-site drainage facilities affect the Orange County land and environment, and so the design criteria established by the Orange County Environmental Management Agency (OCEMA) should also be implemented. Even though the design criteria set by both of these agencies govern the design, there are some distinct differences in the determination of design storm frequency and peak discharges. Consequently, special drainage design criteria have been prepared for these corridors based on discussions with both the agencies.
