Project Description
The Imperial Irrigation District/California Department of Transportation (IID/Caltrans) Water Utility Relocation Program is a multiyear program to address irrigation and drainage system changes required as a result of multiple Caltrans highway projects in the Imperial Valley. The program involves approximately 75 individual projects that must be designed and built by June 2003.
The utility relocation work designed by Parsons is required to permit construction of two new 4-lane expressways, State Highway 111 and State Route 7. These projects are part of a North American Free Trade Agreement border crossing to improve transportation between the U.S. and Mexico. The new highways cut across and through the IID irrigation and drainage systems in many locations, requiring modifications or additions to the infrastructure that consists of open-channel canals and drains, culverts, siphons, and pipes.
The basic program goals and objectives are:
- Design the utility relocations to accommodate the highway projects, yet provide the IID with functionally equivalent irrigation and drainage systems
- Assist IID with planning and managing multiple simultaneous projects and coordinating the actions of internal divisions to ensure each project's success.
- Revise or develop IID standards, policies, or procedures to improve interagency coordination
- Support the Caltrans project phases, schedule objectives, and decision points by providing information or data
The unique challenge of this program is to simultaneously accommodate Caltrans' construction schedule while maintaining full operation of IID's water delivery system.
