Environmental GIS

The Environmental Information Program provides technical support to project planning and delivery by stewarding over 700 GIS data layers crossing a wide range of environmental topics, by building tools and resources to help staff use that data, and by directly generating customized information products (maps and analysis) from that data.  The Program also coordinates non-GIS computer applications that support environmental compliance functions and processes within WSDOT's overall Environmental Management System.

Environmental GIS data layers are researched acquired, re-formatted, and maintained by our Environmental Database Administrator in cooperation with the agency Spatial Database Administrator. Most of these data layers come from the appropriate natural resource, environmental or mapping management groups within federal, state, tribal, or local governments. Therefore the data vary widely in scale and accuracy. Metadata documentation is always provided to assist in using data appropriate data use. The data that WSDOT generates itself is documented and available for download from WSDOT's GeoData Catalog. We do not post data we've acquired from other agencies, so click here to see a listing of the environmental GIS data that WSDOT gets from outside sources.

The Environmental Information Program is also responsible for coordinating non-GIS information technology projects that deliver environmental support to transportation projects and operations. These projects range from updates to existing agency databases, to interagency cooperative projects. Current efforts include:

  • Stormwater information management tools to track and record compliance activities under WSDOT's Municipal Stormwater Permit. 
  • The Commitment Tracking System that records and tracks compliance on environmental requirements for construction projects.
  • Tools to help track and report on sites with hazardous materials issues and compliance with spill prevention plans.
  • Tools to assist tracking and reporting on NEPA/SEPA processes and documentation. 
  • Supporting the development of statewide strategy for infrastructure adaptation to climate change.
  • Tools to assist planning, tracking, and reporting on our wetland mitigation site monitoring obligations.

The Environmental GIS Workbench is an internal tool for agency staff to access these environmental GIS Data Layers. It is an extension to ArcGIS (like a plug-in to your web browser), which provides menu navigation to data on a wide scope of environmental topics and to customized tools for analyzing the environmental context of transportation projects. Training is provided to WSDOT staff upon request. Contact the Environmental GIS Workbench Support person for more information on this application.

Custom GIS and database products. 
 Custom maps, tabular information, web pages, analytic spatial assessments, or new data development / automation / acquisition can be requested through the Environmental Information Program Manager


Overall WSDOT GIS support is provided by several groups distributed throughout the agency who conduct GIS work ranging from GIS infrastructure support to cartographic publications. The Environmental Information Program has applied expertise in environmental and natural resource GIS data and analysis. Other agency expertise areas include transportation data, geotechnical data and analysis, publication cartography, transportation program and project analysis, spatially-enabled application development, and spatial data administration. The Environmental Information Program works closely with these other expert groups through the agency GIS Support Team and by following the agency information technology systems development and management processes.
