The Yorba Linda City Council voted unanimously July 15 to adopt the California Department of Forestry and Fire Protection (Cal Fire) fire hazard severity maps as the city's official designation, while directing staff and the Orange County Fire Authority to seek Cal Fire data and return with any information that could support future amendments.

Why it matters: Residents of the Bryant Ranch area and other hillside neighborhoods told the council they fear the map understates fire risk in a small pocket surrounded by very-high zones, and warned that the designation could affect evacuation capacity if development proceeds at the Bryant Ranch Shopping Center. Council members said they were pressed by community concerns but had no independent, scientific evidence to override Cal Fire's model and therefore adopted the map to meet state deadlines while pursuing further review.

The council met the statutory deadline to adopt the map, but several residents urged the city to raise the classification for a specific parcel near Bryant Ranch to "very high." Members of the public described prior evacuations in 2008 and more recent near-misses during which travel out of the hills became slow or blocked.

"Adding hundreds of new residents ... would severely strain an already limited evacuation route," resident Tagdeep Bridal told the council during public comment. Robin Weinberg, another Bryant Ranch resident, said traffic and evacuation bottlenecks made additional housing at the shopping center unsafe.

City Attorney Todd Lifton advised the council that state law (cited during the meeting as Government Code section 51179 and related provisions) allows a local agency to increase a designation to very high only on the basis of "substantial evidence." Lifton and fire officials told the council they had no such evidence in the record to justify an immediate change.

Orange County Fire Authority (OCFA) division chief Kevin Fetterman told the council the maps were produced by Cal Fire using a statewide model that incorporates dozens of data points including topography and fuel type; OCFA did not create or control the model and could not, on its own, replicate that analysis.

After debating policy options and hearing repeated public pleas, the council voted 5-0 to adopt the map and simultaneously directed OCFA to contact Cal Fire to request the underlying data and clarification of the mapping and potential amendment process. Councilmembers asked OCFA to report back on that outreach and on whether a formal appeal or amendment path exists. Councilmember Peggy Wong explicitly proposed the dual approach: adopt now to meet the 120-day requirement, and seek a route to amendment if the state provides additional data or accepts review.

Next steps: The council recorded a unanimous adoption and asked staff to return with OCFA's findings and any Cal Fire responses at a future meeting, with emphasis on whether the city can develop "substantial evidence" to support any local change. Council members also asked that state representatives be engaged to press for clearer processes in future map updates.

Resident voices: Dozens of residents spoke during the public-comment period. Peter Meng, a professional engineer, urged immediate removal of overgrown fuel near Chicago Avenue and said permits should be suspended until hazards are mitigated; multiple residents described slow evacuation experiences during the 2008 Freeway Complex Fire and urged greater caution in any local land-use decisions affecting evacuation routes.

The council's action does not itself change construction approvals or directly block development; staff and the city attorney advised that shifting a designation to very high mostly affects building standards and notification requirements and does not in itself prevent a developer from pursuing permits or CEQA exemptions under state housing laws.

The meeting transcript shows the council's final motion passed unanimously and included the direction to OCFA to engage Cal Fire and return with findings that could support further action.
