    Airport Noise DNLS 65 and 68 Overlay Zone. There are several contours within the zone. The boundaries of the 65 DNL and 68 DNL noise contours are based on the 1990 Portland International Airport Noise Abatement Plan. The 55 DNL noise contour is based on the 2035 50th Percentile Forecast Noise Exposure Map in the 2010 Portland International Airport Master Plan Update. A set of quarter-section maps, known as the PDX Noise Zone Maps, is available for viewing at the Development Services Center. The maps are the official reference maps for the PDX Noise Zone regulations. The maps show the 55 DNL noise contour and each successively higher noise contour in one DNL increments. https://www.portlandoregon.gov/bps/article/53357 Zoning Code 05/04/20 03:35 PM
    Airport Noise Impact Overlay Zone The Portland International Airport Noise Impact Overlay Zone reduces the impact of aircraft noise on development within the noise impact area surrounding the Portland International Airport. The zone achieves this by limiting residential densities and by requiring noise insulation, noise disclosure statements, and noise easements. https://www.portlandoregon.gov/bps/article/53357 Zoning Code 05/04/20 03:35 PM
