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.

- Closure limits on the plan do not match the approved permit exactly.
