Showing ordinances that apply to Temescal Valley, CA
Temescal Valley is an unincorporated community (population 26,232) in Riverside County, California. Because Temescal Valley is not an incorporated city, it does not have its own municipal code. Instead, Riverside County ordinances apply directly to properties here. The industrial noise rules below are the ones that govern your area.
Industrial and manufacturing uses in unincorporated Riverside County must comply with Ord. 847 dBA limits at the nearest residential property line 24 hours per day.
Ordinance No. 847 holds industrial, manufacturing, logistics, warehousing, and mineral-extraction operations to specific exterior noise limits at the receiving property line. Typical caps are about 55 dBA daytime and 45 dBA nighttime at adjacent residential parcels, with higher limits permitted on other industrial sites. Sound measurements use an A-weighted slow response, and cumulative duration rules apply (e.g., limits may be exceeded by 5 dBA for no more than 15 minutes per hour). Conditional use permits for truck yards, aggregate plants, data centers, and similar uses often impose tighter CUP conditions including backup-alarm modifications, enclosed loading bays, and truck routing. Ongoing violations can trigger permit revocation hearings in addition to administrative fines. CEQA review for new industrial projects requires noise studies demonstrating compliance at sensitive receptors, particularly in the Coachella Valley and Jurupa Valley edges.
Administrative citations, CUP revocation proceedings, and injunctive actions; fines can reach thousands per day for continuing violations.
