Summary
Gresham requires heliport developers to submit a professional acoustical study and noise-mitigation plan before a heliport can win Special Use Review approval, addressing flight paths, speeds, hours of use, and buffers near noise-sensitive properties.
The applicant shall provide an acoustical and mitigation plan report that details the design and measures to be taken which will minimize noise impacts to noise sensitive units as defined in Article 7.20. Noise Control Code of the Gresham Revised Code. The report, at a minimum, shall discuss and make recommendations for: 1. Best management practices concerning preferred approach/departure flight paths; 2. Preferred approach/departure path slopes; 3. Preferred approach/departure air speeds; 4. Preferred times of use.

Any heliport proposed in Gresham goes through Type II Special Use Review under Development Code Section 8.0120, and the applicant must submit an acoustical and mitigation plan prepared by a professional experienced in airport noise evaluation. The report must address preferred approach/departure flight paths, path slopes, air speeds, and hours of use, plus proposed hours of operation, aircraft type and size, and trip counts. Landing and takeoff pads must sit at least 200 feet from residential, mixed-use, and neighborhood-commercial property lines (50 feet from other property lines), with a 20-foot landscaped buffer around pads and refueling facilities.
