The Department of Transportation is a good steward of California’s limited water resources. The Department actively manages, promotes and implements water conservation practices within the highway transportation system and associated facilities. Cost effective and appropriate water conservation strategies are employed in the design, construction, operation and maintenance of transportation facilities including, to the maximum extent practicable, the use of recycled water and state of the art irrigation technology for highway landscaping.

|Caltrans Native Grass Sod Research
Native grass was found to provide the following benefits:
TransPLANT is an advisory aid to Caltrans Landscape Architects as they select grasses, forbes and other plants for erosion control, revegetation, biofiltration, and other planting work.
Use of transPLANT is intended to supplement, not replace, knowledge of local areas held by District personnel. A visit to the project site is still recommended before the final selection of plant materials is made.
Prepared by University of California Davis, this tool provides a method to select the most appropriate native grass species based upon criteria such as county, rainfall, elevation, and plant community.
