The noise exposure maps for Paine Field were originally prepared as a component of a Part 150 Noise and Land Use Compatibility Study that was adopted by Snohomish County in July 1995. Those noise exposure maps, with a five-year planning horizon, are now out of date and the adopted forecasts contained in the 2002 Master Plan Update for Paine Field have been used as a basis to formulate updated Noise Exposure Maps.
The need to update the noise exposure maps was identified as a result of the public meetings and process used in the preparation of the 2002 Master Plan Update. Aircraft operation numbers and types of aircraft have changed since the preparation of the last Noise Exposure Maps, especially with the removal of military helicopter operations from the airport. The Noise Compatibility Recommendations contained in the previous Part 150 Study have not been amended and are still current.
