Cupertino planners review state‑required update to health and safety element, focus on flood, heat and wildfire risks

Cupertino Planning Commission members spent most of their July 8 study session reviewing a state‑law‑driven update to the city's health and safety element, hearing from PlaceWorks consultants about new legal requirements, a citywide vulnerability assessment and an evacuation study and offering initial policy direction on evacuation routes, fire protection, floodplain development and climate resilience.

"A safety element is one of the mandatory elements of a general plan focusing on natural and human caused hazards within and surrounding Cupertino," PlaceWorks project manager Jacqueline Protsman Rohrer told the commission, explaining that the update responds to recent state law changes and the city's recently updated housing element.

PlaceWorks described two supporting studies for the update: an AB 747 evacuation study by Bear and Pierce to identify evacuation routes and locations, and a vulnerability assessment prepared under SB 379 to evaluate how climate‑related hazards could affect people and critical assets. The vulnerability assessment examined eight climate hazards across 45 population groups and assets and found Cupertino's populations and infrastructure are most vulnerable to flooding, extreme heat and wildfire; residents with chronic illnesses or disabilities, seniors living alone, households in poverty and people experiencing homelessness were flagged as especially vulnerable. The assessment also identified energy and communications infrastructure, major roadways and water/wastewater systems as high‑risk assets.

Consultants presented a set of proposed policy concepts organized around emergency preparedness and response, fire hazards, hazardous materials, seismic and geologic hazards, flooding and a new climate change resilience topic to satisfy SB 379 requirements. Proposed policies ranged from continuing multiagency coordination and multilingual public notices to development‑focused measures such as requiring two independent ingress/egress routes for new development in constrained areas and limiting new residential development in very high fire severity zones.

Commission discussion and public comment focused on several recurring implementation issues. Commissioners and speakers urged stronger, clearer public education and outreach so residents understand what being in a newly designated high or very high fire hazard zone means and who is responsible for what; expanding volunteers and CERT training; ensuring the city's emergency operations center (EOC) is adequately staffed and that the city plans for battery backup at key facilities; and mapping and publicizing hazardous sites and water tanks. Resident Jennifer Griffin and others urged continued CEQA oversight for large projects such as data centers (a public comment separate from this agenda item). Peggy Griffin asked the commission to avoid adding new, ongoing financial burdens or mandatory inspections for homeowners who are not making changes to their properties.

Commissioners pressed staff and PlaceWorks on practical details and limits of local authority. Staff and consultants noted that the safety element is a policy document that must be consistent with state law and other city plans; changes to building code requirements fall under the building and fire codes and are not directly set by the general plan update. Commissioners asked for clearer differentiation in policy language between standards or requirements that would apply to new development (for example, multi‑unit or R‑3/R‑4 projects) and those that would affect existing single‑family homeowners; consultants said policy concepts can be drafted to specify whether they apply to new development, redevelopment or existing development.

Other points raised by commissioners and the public included: stronger interagency coordination with county entities and the Lehigh quarry west of the city (several commissioners asked staff to explore how quarry lands and operations should be included in collaboration or mitigation); adding noise and urban forest (street tree canopy) considerations to the update; and treating infrastructure resilience (energy and communications grid redundancy, solar+storage and ham radio/volunteer communications) as part of climate resilience and emergency preparedness. Staff said the vulnerability assessment and evacuation study will be appended to the safety element background materials and that a draft safety element will return for public review later this year and proceed to hearings for adoption by the council, with final hearings anticipated before the end of 2025.

No formal action was taken at the study session; PlaceWorks and staff received the commission's input and will prepare draft policies and background materials for subsequent hearings. The commission asked staff to consider adding a noise review, to be explicit when a policy applies only to new development, and to explore options for broader public engagement and coordination with county agencies and the quarry. PlaceWorks and staff indicated they will incorporate the commissioners'feedback into the draft and suggested the background vulnerability assessment and evacuation study will be released with the draft safety element for public review.

The study session closed after roughly an hour and a half of presentation and discussion; staff said an updated draft will be posted when available and the item will return for recommendation to the city council.
