Nevada County planning commission approves Penn Valley Community Center with conditions

The Nevada County Planning Commission voted unanimously to approve a conditional use permit for a proposed Penn Valley Community Center and its associated mitigated negative declaration and Oak Resources Management Plan. The project, sited at 10592 Spenceville Road on a 4.77‑acre parcel, will include a 10,000‑square‑foot primary building, a 1,134‑square‑foot covered outdoor seating area, two 1,728‑square‑foot open pavilions, a commercial kitchen, meeting rooms, and garden and detention features.

Staff Principal Planner Steve Geiger told the commission that the project will be served by public water, retain an on‑site well for irrigation, and include 140 parking spaces where 120 are required; 51 spaces are proposed as gravel and 89 as paved. An environmental review produced a mitigated negative declaration and 19 mitigation measures addressing biological resources, air quality, noise, and hydrology. Geiger said a traffic study estimated weekday trips (staff noted the project generates under county thresholds for a significant peak‑hour impact) and that the project is not expected to degrade the nearby Spenceville Road intersection’s level of service.

The applicant, Teresa Dietrich of the Penn Valley Community Foundation, and consultant Christopher Ring described the center as community‑funded and designed to host civic meetings, workforce development, after‑school programs, senior wellness, visitors services and to function as a warming/cooling and emergency refuge with backup generator power and a commercial kitchen. They highlighted plans for high‑speed broadband, EV charging and ADA accessibility, and said the design preserves a landmark blue oak (a 42‑inch tree) and a 0.45‑acre oak grove. The Oak Resources Management Plan recommends two years of post‑construction monitoring by a certified arborist and compensatory mitigation if the protected oak’s health declines.

Commissioners pressed the applicant on site design details: the width and turning radius of an internal fire access and cul‑de‑sac, pedestrian circulation and sidewalks through the parking/fire‑access area, the choice to allow a portion of parking to be gravel to preserve rural character, the absence of exterior classroom windows (applicant cited security and donor‑wall design), and noise and lighting controls. Staff confirmed three recommended noise mitigation measures: events limited to 7 a.m.–10 p.m., amplified music restricted to interior spaces, and sound‑control design features in the building plan; two lighting mitigation measures require fixtures to be fully shielded and a final photometric plan demonstrating zero light trespass at property lines.

Public commenters were split. A nearby resident (first name Theresa) objected to the site because of traffic, noise, lights, potential impacts on well water and concerns about Wi‑Fi “towers.” Longtime resident Dane Atlin and Penn Valley Chamber President Anna Lo spoke in favor, saying the facility would strengthen emergency response and provide needed meeting and event space. Staff clarified that no towers are proposed, the site will receive NID public water for building service, and the on‑site well will remain for irrigation.

Following discussion, commissioners moved to adopt the mitigated negative declaration and mitigation monitoring program, to approve Conditional Use Permit CUP‑25‑0004 to permit the community event facility as proposed, and to approve Oak Resources Management Plan MGT‑26‑0001; all actions passed unanimously. The approvals are subject to the conditions and mitigation measures identified in the staff report and attachments.

Next steps include finalizing required building‑department reviews and permit processing before any construction. The project team and staff will carry out the mitigation and monitoring obligations specified in the approvals.
