Description: The Oregon Department of Transportation (ODOT) has developed a geographic information system (GIS)-based sensitive resource inventory along nearly 6,000 miles of state highway as part of its Salmon Resources and Sensitive Area Mapping Project. The primary purpose of the project is to provide accurate resource protection maps to roadway maintenance crews so that mowing, pesticide application, and other activities do not harm salmon species and other sensitive resources. The comprehensive resource inventory was initially developed by using color infrared digital imagery with 2-foot resolution. Other sensitive resource features were recorded from current knowledge bases and limited roadside surveying, and from modeling of interactions between multiple resources and data layers. Products have included resource maps in 0.01-mile segments, which indicate where sensitive resources are present (including which side of the road). ODOT has supplied these maps to all districts for use by biologists, planners, and maintenance managers. Restricted Activity Zones for maintenance are denoted along a horizontal straightline as a simple color-coding scheme of green, amber and red to indicate, for each major class of maintenance activity (e.g., surface and shoulder work, vegetation management, snow and ice removal, etc.), whether or not that activity should be cautioned or restricted along the left or right side of a given 0.01-mile segment of highway. The library of GIS data resulting from the project has given ODOT’s regional staff a detailed environmental inventory of ecological resources, facilitating consideration of sensitive natural resource features when planning and designing transportation system improvements. The project's related maps, GPS and web applications have proven to be reliable project scoping tools to help avoid impacting sensitive resources including streams, wetlands, or rare plant populations. Project data has remained current through subsequent remapping of the best available imagery, shared interagency datasets, layout and application refinement, and ongoing communication with participating staff.
