Interim PID (PIR) SWDR

The California Department of Transportation has piloted two new PID (PIR) SWDR processes. The first process should be used by engineers and landscape architects that like less guidance. The second process is for those who prefer more. Consult your local Design Stormwater Coordinator to request the most recent version of the PID SWDR. 

A one-page Excel SWDR spreadsheet is embedded with guidance and is available upon request to your Caltrans representative. 

Typical Short and Long Forms are minimized to meet the new PIR process. Example reports are available to see what a typical one looks like. A Guide is provided including PIR SWDR Risk Management and is available upon request to your Caltrans representative.
