Irrigation systems are used by Landscape Architects to provide supplemental water to trees, shrubs and groundcover, as required to support aesthetic, safety, environmental mitigation, stormwater pollution prevention, and erosion control. Irrigations systems support planting that helps integrate the highway within its natural or built environment to provide human scale and maintain an area’s unique visual context.
Cost Effective Design
Irrigation must be cost effective. Landscape architects design irrigation systems that have low life-cycle costs and able to endure for the long-term.
Caltrans is a good steward of California’s limited water resources and 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, and maintenance of transportation facilities including "Smart" Irrigation Controllers, wood and gravel mulches, hardscape surfaces, and recycled water to the maximum extext possible.
Each District has standardized on one (or sometimes two) "Smart" irrigation controller systems. Standardizing on a single system streamlines both construction and maintenance activities by reducing training needs as well as reducing the need to stockpile a variety of spare parts. The list below identifies the controller systems that each District has selected as their District (Maintenance Region) standard.

Public Information Finding (PIF) Information
It is not difficult for a District to obtain Blanket PIF approval from the FHWA. If you would like to pursue obtaining a District Blanket RICS approval from FHWA, review and modify the submittal from District 11 attached below, and submit it to your FHWA coordinator for review and approval.
