Public meeting held on SB 35 mixed‑use proposal in Diamond Springs as residents raise safety and traffic concerns

The board held a public meeting Aug. 26 after county staff received a Senate Bill 35 (SB 35) notice of intent for a mixed‑use project in Diamond Springs that would add 16 residential units over an existing commercial building on Pleasant Valley Road.

Staff outline and legal context

County planners explained SB 35’s two‑track, largely ministerial process: an initial eligibility review (60 days and limited resubmittal time) and an objective design‑review track (90 days for smaller projects) that must rely on objective, externally referenced standards rather than subjective judgments. The law applies where jurisdictions have not met Regional Housing Needs Allocation (RHNA) targets and includes special rules for projects within opportunity‑map “moderate” or “low” resource census tracts; those maps triggered the board meeting required by SB 4/23 once staff received the developer’s notice of intent.

Staff described the proposed Diamond Springs site: a commercial parcel on Pleasant Valley Road zoned for mixed use where the applicant proposes two stories of housing (16 units) above a roughly 4,000‑square‑foot commercial building. The parcel lies in a census‑designated moderate‑resource area, which is why the SB 35 notice required the board‑level meeting.

Public comments and supervisor concerns

Dozens of residents, neighborhood representatives and businesses spoke. Most speakers said they support affordable housing in principle but urged the board and staff to consider the site’s traffic, evacuation and public‑safety implications before the county advances ministerial approvals. Specific concerns raised included:

- Congestion and safety at Pleasant Valley Road, Zandonella and nearby intersections; witnesses said traffic routinely backs up and that left turns can be difficult or unsafe. Several residents and supervisors urged a traffic study and larger evacuation analysis that aggregates planned and approved projects in the corridor. - Parking, site geometry and on‑site feasibility: the proposal’s preliminary materials indicated limited parking and asked whether the existing structure could support an addition. - The SB 35 timeline and ministerial standard: several residents asked whether the county had discretion to require studies or conditions beyond objective standards. County counsel and staff said SB 35 restricts discretionary requirements and places emphasis on objective, verifiable standards. Staff pointed to recently adopted “interim objective standards” that apply to design review under SB 35.

Tribal consultation, timing and enforcement

Staff noted SB 35 requires pre‑application tribal consultation; if a tribal resource is identified and an agreement cannot be reached, the project cannot proceed under SB 35. County counsel also explained HCD’s enforcement role: the Department of Housing and Community Development issues technical‑assistance letters and can escalate disputes; in extreme cases HCD can seek legal remedies or other enforcement steps against a local agency.

Where things stand

No application for a ministerial SB 35 housing permit has yet been filed. County planners said the meeting was required because the parcel falls in a moderate‑resource census tract and that any developer affidavit and formal application will trigger the timelines and objective review described. Supervisors asked staff to seek fuller traffic analysis of corridor projects and to coordinate with Caltrans or regional planners on evacuation modeling and mitigation.

Why this matters

SB 35 is a statewide statute intended to accelerate housing production by limiting discretionary local review; it can improve housing supply but also restrict local discretion to address site‑specific public‑safety and infrastructure impacts. In Diamond Springs the public meeting highlighted competing objectives: the county’s need for affordable housing versus resident concerns about road capacity and emergency evacuations. County staff will receive and file public comments and expects further technical review if the applicant files a formal SB 35 application.
