Open data policy

See the details of our open data policy and plan. 

The Legislature has found that government records and information are a vital resource to both government operations and to the public that government serves. Broad public access to state government records and information has potential for expanding citizen access to that information and for improving government services. Electronic methods for locating and transferring information can improve linkages between and among citizens, organizations, businesses, and governments. (See RCW 43.41A.115)

WSDOT's Open Data Plan (PDF 100KB) sets forth our plan to establish a path to provide open data and meets the Office of the Chief Information Officer's Policy 187.
