Cupertino council grills developers and fire officials over 51‑unit Summerhill Homes project amid fire‑safety and contamination concerns

Mayor Moore opened the special City Council meeting on April 1 to consider a tentative map, architectural/site approvals and a tree removal permit for a 51‑unit townhome condominium project proposed on Eviolich (Evolich) Court in the Monte Vista neighborhood.

City staff presented the application and noted it invokes several state housing laws including the Housing Accountability Act, SB 330 and the Density Bonus Law. Senior planner Emmy Sugiyama told the council the project would include 51 units across 10 buildings, with 10 below‑market‑rate units, two protected oak trees, and requests for five density‑bonus waivers (reduced setbacks, smaller private open‑space clearance, taller maximum heights, increased FAR and narrower parking spaces). The staff report and a third‑party peer review concluded the project meets objective standards for the requested exemptions and recommended the council adopt draft resolutions finding the project exempt under Assembly Bill 130; staff said the AB 130 decision deadline is April 4.

Council members and the public focused much of the evening on public‑safety and environmental concerns. Mayor Moore and others identified historical site uses in environmental site assessments — multiple drums, an above‑ground diesel tank and four underground storage tanks — and two on‑site pits of unknown contents. Brad Fox of the Santa Clara County Fire Department said the county issued a closure permit for two tanks, inspected removals and forwarded soil‑sample reports to county environmental health; at that point, fire staff reported no further action was required based on the closure permit results.

"We did issue a closure permit for the two tanks that were found on‑site," Brad Fox said. "The action that they found was, no further action was required, and they closed their process." (Brad Fox, Santa Clara County Fire Department)

Mayor Moore and others pressed staff on whether the site's soils and pits had been fully characterized and whether the city or county had imposed regulatory oversight prior to mapping approvals. City staff said the applicant provided Phase I/II assessments that were peer‑reviewed by the city’s consultant, and that a soil management plan (SMP) condition is included to require testing and regulatory oversight if contaminated soils are encountered during grading or construction. Staff said additional borings and geotechnical sampling would be completed as part of construction drawings before building permits are issued.

Fire‑safety debate dominated council discussion. Because the site is now mapped in a "very high" fire hazard severity zone, the California fire‑safety standard in 14 CCR (commonly referenced as PRC/4290) establishes a 30‑foot setback baseline. The applicant has requested an exception that would allow buildings closer to property lines (a reduction to roughly a 10‑foot setback) while offering a mitigation package described by county fire staff as "same practical effect" (SPE): a combination of a non‑combustible zone, exterior sprinklers, 1‑hour exterior wall ratings, home‑hardening components (non‑combustible exterior materials, tempered glass), and other operational and access measures.

Santa Clara County fire staff described SPE as a systems‑based evaluation and defended its use. "These mitigations work together as a system," the fire chief said. "When you combine home hardening, the five‑foot non‑combustible zone and the exterior sprinklers, the cumulative effect is expected to provide the same practical effect in these scenarios."

Several council members — including Vice Mayor Chao and Councilmember Wong — pushed back, calling for clearer, objective standards that tie specific mitigation measures to quantified reductions in radiant heat and structure‑to‑structure ignition risk. Councilmember Wong cited NIST guidance and asked whether a five‑foot non‑combustible buffer plus mechanical systems could realistically replace a 30‑foot passive setback for older adjacent homes. Fire staff and city legal counsel said the SPE determination follows the regulations in 12.70/12.76 (the state fire code exception process) and that the SPE evaluation is designed to be applied case‑by‑case using the objective measures in that framework.

Legal and procedural issues were also raised. Councilmembers asked whether a formal Fair Political Practices Commission (FPPC) opinion should have been sought before accepting a councilmember's participation in the vote. The interim city attorney, Floyd Andrews, said he and an independent appraiser reviewed Councilmember Mohan’s property proximity and concluded no disqualifying conflict existed; Mohan said she agreed and would participate in deliberations.

Attorney Pam Lee, advising on housing law, told the council that the AB 130 CEQA exemption may apply when a project meets the statutory criteria and objective standards, but that underlying fire‑safety approvals and SPE findings need to be defensible and consistent with the code's requirements.

Council members repeatedly asked whether evacuation capacity and regional traffic constraints — referenced in a Fair & Peer study that shows high volumes on Foothill and Stevens Creek in a wildfire scenario — had been reconciled with staff’s safety findings. Fire staff said evacuation modeling and some elements of broader transportation capacity were outside the SPE evaluation scope for the exception request and noted county fire acts as a subject‑matter expert for operational response and evacuations.

No final council vote was recorded by the end of the evening. Staff reiterated that many technical elements (sprinkler layouts, specific BESS/ESS battery locations, final vegetation/fuel‑management plans) are reviewed in detail at building‑permit stage as deferred submittals and that permits would not be approved if required measures were not demonstrated in those submittals. The council took a five‑minute recess after extended Q&A; the item remained under consideration with staff direction to provide follow‑up information on precedent for exception denials and the county's regulatory closure documentation.

What’s next: staff recommended adopting draft resolutions to find the project exempt under AB 130 and to approve permits; the council had not voted on those resolutions by the time of the recess. Staff said a final ministerial/administrative calendar constraint under AB 130 requires a decision by April 4 on the application as submitted.
