Full Breakdown
Linn County's zoning code treats outdoor amphitheaters and stadiums, the venues built for outdoor concerts and live events, as a specific commercial use with its own standards. A major site plan is required, and the site must be located at least 500 feet from the boundary of any residentially zoned property. County approval must specify the venue's days and hours of operation, and noise impacts on surrounding land have to be considered and mitigated as part of that approval process. The county doesn't set a decibel ceiling for these venues; instead it controls where they can be built and when they can run. Cedar Rapids and Marion regulate outdoor entertainment venues separately.
Violations & Fines
Building or operating an outdoor amphitheater without the required site plan, separation distance, or approved hours is a UDC violation, pursued as a county infraction, civil penalty, injunctive abatement, or simple misdemeanor.
