San Joaquin County planners seek input on rules for special events, threshold for neighbor notice

San Joaquin County planning staff asked the Planning Commission for policy input on updating the county's development title rules for special events, focusing discussion on when higher levels of review or public notice should be required.

Principal Planner Megan Ahire said current rules require a temporary use permit for all special events of 75 people or more, issued ministerially and renewed annually up to four events per year. She said staff wants feedback on whether the county should tier review by event size or other triggers and what thresholds should trigger additional requirements such as public notice or discretionary review.

Commissioners and members of the public raised a range of issues: whether thresholds should be based on attendees or zoning context; requiring neighbor notification for large or potentially disruptive events; tying additional review to alcohol service, amplified sound, occupant load, traffic impacts or public-safety staffing; and whether religious assemblies should be treated differently.

Megan Ahire said some events can range from small family gatherings to multi-thousand-person festivals and that county practice routes special event permit applications to departments including Fire, Environmental Health, Public Works and the Sheriff's Office for conditions and sign-offs. She noted the county adopted a 75-person threshold in a prior Development Title update and reiterated staff's intent to avoid burdening minor family gatherings while addressing large, commercially organized events that can overwhelm rural roads and nearby homes.

Several commissioners and stakeholders suggested practical changes. A commissioner recommended basing thresholds on attendee counts; another suggested a 300-person threshold for more robust review, while others emphasized that context matters (e.g., 300 people in a remote 40-acre field differs from 75 people in a residential neighborhood). Participants discussed a middle path: retain a streamlined temporary permit for smaller events but require neighbor notification and more detailed plans (traffic control, parking, sanitation, first aid, amplified-sound mitigation) when events exceed a higher numeric threshold or when located in sensitive zones.

Speakers with industry experience described operational practices. One participant who runs event venues said commercially permitted event centers can manage large gatherings (citing capacities up to 1,000) and routinely contract for CHP, sheriff security and emergency medical services; she noted large religious events had drawn tens of thousands in past years but were organized with public safety plans and agency coordination. Fire and public-safety representatives emphasized occupancy limits, first-aid staffing, and fire-permit standards for cooking and vendor operations.

Staff also raised technical implementation items: whether to require decibel meters for amplified sound (staff previously added a decibel reader requirement in the Development Title), how to measure and enforce noise across a property, whether to require on-site attendee counting and more specific parking calculations, and whether cleanup must occur within 24 hours. For unpermitted events, current code allows precluding a property owner from applying for further temporary permits that year; attendees suggested graduated fines or escalating penalties for repeat violations.

Planning staff did not propose final ordinance language at the meeting; commissioners asked staff to return with draft options that consider (1) numeric thresholds by attendee counts, (2) special rules tied to zoning context, (3) required plans for traffic, parking, sanitation and safety tied to thresholds, (4) neighbor-notification procedures for larger or disruptive events, (5) clearer noise enforcement and decibel methods, and (6) graduated enforcement for repeat unpermitted events. Staff said it will consult other counties for models and return with draft language for further discussion.

The item was a workshop; no formal vote was taken.
