California / Field Use Notes
Used at the point of a permitted local-street closure in California, in place of ROAD CLOSED where STREET is the appropriate legend, with an authorizing encroachment permit.
In Los Angeles, full closures typically require coordination with LADOT for signal timing, LA County Metro where transit routes are affected, and public-notice requirements under City or county ordinance. On state highways in LA County, Caltrans District 7 reviews the encroachment permit; county roads are permitted by LA County DPW. Confirm closure limits match the approved permit exactly.
Common Plan Review Comments
- Closure limits on the plan do not match the approved permit exactly.
- Closure not backed by advance warning and a signed detour.
- Local-access provisions unclear (especially for ROAD CLOSED TO THRU TRAFFIC).
- Barricade type (e.g., Type III) not specified.
Confirm the closure is permitted and the advance detour is signed. Public Ready reviews street-closure signing and detours.
