Atherton council adopts updated safety element to reflect climate and evacuation guidance

Tom Ford, the town’s senior planner, presented a staff-backed proposal to amend Atherton’s general plan to update the community safety element, the open space and conservation element, and the circulation element.

Consultant Tammy Seal of PlaceWorks told the council the updates incorporate recent climate vulnerability information, stronger evacuation and ingress/egress guidance for residential areas, and new state requirements that treat extreme heat as a hazard. Seal said the project also aligns the safety element with the county’s multi-jurisdictional hazard mitigation plan and with new state guidance on timing and content for safety-element updates.

Ford and Seal said the revisions include new text, maps, goals and implementation actions. They emphasized that the general-plan amendment is a program-level policy document covered by a common-sense CEQA exemption and that any later physical projects or implementation measures would require separate environmental review.

Councilmembers asked whether the update prescribes fixes for neighborhoods the hazard maps identify as having constrained evacuation routes. Seal and staff said the general plan provides policy direction and that more specific operational solutions would be addressed through Atherton’s emergency operations plan and later implementing projects. Councilmembers also asked about outreach to potentially affected residents and whether the update could affect insurance; staff said they will conduct targeted outreach after adoption and that the town cannot control private insurer decisions but aims to reduce risk through clear policies and coordination with state agencies.

During public comment, residents urged proactive outreach to residents near Walsh Road and Bear Gulch, and to newly arrived households, asking the town to provide clear guidance and printed materials. Staff agreed to expand outreach connected with the adopted element.

On a motion and second, the council adopted a resolution to amend the general plan to implement the safety-element, open-space and circulation updates and directed staff to file a notice of exemption and forward the adopted element to the California Office of Emergency Services and other required state agencies. The council also requested follow-up on implementation measures and community outreach.
