Island County GISThis GIS dataset was created to identify the day-night average noise levels around both Ault Field and Outlying Field (OLF) Coupeville. This created the Air Installations Compatible Use Zones (AICUZ) noise contours. This was revised in 2005 through a study done by the Navy in March 2005. The Onyx Group was the primary consultants for this study. The GIS work for the AICUZ noise zones was done by Wyle Laboratories in California.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/b01b8292cb7a43558903d67ea380215e_0engIsland County Open Data PortalPublicNoise Contours [Washington (State)--Island County]Web servicesWashington (State)--Island CountyWashington (State)Last Modified: 2018-09-10
