Mountain Brief
The Topanga community platform we’re operating with TCEP — start with the resident app beta.
How it holds
Mountain Brief is built for moments when conflicting alerts and dead zones leave people guessing.
See evacuation posture, community conditions, and guidance for the place you actually live.
A Resident Node stays nearby — listening for updates when you’re not staring at a screen.
Internet first. RF fallback when cell or Wi‑Fi drop — so the message can still get through.
In the home
This beta track is the resident app: install it, use it as a Topanga resident would, and tell us what’s clear.
Topanga pilot
Mountain Brief supports local preparedness and TCEP workflows. It does not replace official LA County / Genasys alerts.
In a real emergency, follow official instructions from authorities.
