Topanga: a WhatsApp group becomes fire infrastructure

Years before the fire, community organizer Scott Vineberg started a WhatsApp group for Topanga — the canyon community west of Los Angeles — as a simple way for neighbours to share local events, workshops, and a kind of free, neighbourly home-sharing.

When the Palisades Fire tore through the area in January 2025, that everyday group chat became something else entirely: the nexus of the community’s fire response. What had been a place to swap workshop invites turned into a backbone for evacuation information, mutual aid, and neighbour-to-neighbour coordination.

What happened

As Scott described it at a Metagov seminar, the original couple of small WhatsApp groups grew into a WhatsApp Community of around 26 channels and roughly 2,000 people — mutual aid, neighbourhood organizing, peer-to-peer communication — until it bumped against WhatsApp’s size limit. Alongside it, neighbours ran “Topanga STRONG” emergency-preparedness meetings and stood up a dedicated TopangaSAFE WhatsApp community for fire coordination.

The striking part isn’t the app. It’s that resilience ran on the infrastructure people already had and already trusted. Attempts to move everyone onto a more capable platform (like Telegram) stalled — people are averse to installing new things, especially in a crisis. The group chat worked precisely because it was already in everyone’s pocket.

Why it matters for citizen infrastructure

This is citizen infrastructure in its rawest form, and it surfaces lessons the field keeps relearning:

• Meet people where they are. The most powerful tool is often the unglamorous one everyone already uses, not the purpose-built platform.
• The hard part isn’t the tech. Scott’s frustration afterwards wasn’t a lack of apps — it was the missing connective tissue: a simple community directory, a way to schedule across everyone’s different channels, a way to bridge people who live in WhatsApp, SMS, and email without forcing them onto one platform. Networks like Mutual Aid LA Network build exactly this at the city scale — a searchable directory of mutual-aid groups across LA — but it rarely exists at the hyperlocal level a canyon community needs.
• Crisis reveals the gap. Communities discover what infrastructure they’re missing exactly when they need it most — and the energy of a crisis is hard to carry into the calm afterwards.

Scott has since worked with bridging and community-building groups, including the Harwood Institute, to turn that fire-forged momentum into ongoing local organizing.
