Red Rocks Ranch Sensory Noise and Odor Impact Assessment Map

Conducted the Sensory Noise and Odor Impact Assessments for the proposed master-planned mixed-use community consisting of 1,350 dwelling units, a neighborhood commercial center, a civic use planning area, a school, and a planned open space and parks system on 353.7 acres within the Rooney Valley. The primary noise sources affecting the site included vehicular traffic traveling along C-470 and Morrison Road, racetrack events at Bandimere Speedway, and concerts at Red Rocks Amphitheater. The noise assessment consisted of measuring ambient noise levels at the project site, modeling future noise levels from traffic and event noise sources using SoundPLAN, identifying noise impacts, and recommending noise abatement and mitigation measures to reduce exterior and interior noise levels at proposed use areas to meet Jefferson County, State of Colorado, and U.S. Department of Housing and Urban Development (HUD) thresholds and to reduce operational and construction noise levels generated by the project at nearby noise sensitive areas. Noise contour maps showing the noise exposure at the site from each of the primary noise sources were developed and provided. The odor assessment reviewed the proposed development with respect to the Colorado Air Quality Control Standards. Potential sources of odors in the area included a wastewater treatment plant, vehicles utilizing Bandimere Speedway, and vehicular traffic traveling along C-470. Recommendations were made to control odors to avoid complaints from future residents.
