REPORT A PROBLEM

Report it. Follow through.

We check the address and existing reports, then hand you off to LA 311.

How this worksChoose an issue → Check the address & existing reports → Send it to LA 311 → Follow your case

GroundWatch does not submit requests to the City. It checks the address, then opens MyLA311, your phone or an email written for you. No passwords or private details here.

HOW WE MEASURE

A few important distinctions

Reports ≠ reality

311 reports are unverified requests, not proof of a problem at an address.

Model ≠ monitor

Air values are regional model estimates.

City closed ≠ independently verified

“Closed” is the City’s status, not proof the problem is gone.
