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.
The following one-page Excel SWDR spreadsheet is embedded with guidance.
Typical Short and Long Forms are minimized to meet the new PIR process. Example reports are provided to see what a typical one looks like. A Guide is provided including PIR SWDR Risk Management.
