I want to do 2 things here where i live in San Francisco, anyone have advice for me on where to start?

1 - I want to start or join a coalition of folks looking to get this implemented in California

2 - I want to contact the city/owner of the specific digital signs right outside my window of my apartment that are on 24/7, loud, and have their glass broken monthly and then wait for the glass to be replaced for weeks. It's a public hazard.
