About the Map and Records Center

The King County Map and Records Center is a repository for documents associated with the establishment and construction of roads in unincorporated King County for the King County Road Services Division.

Our records collection includes design and construction project files, correspondence, contracts, agreements, safety studies, field books and technical reports. We also keep a collection of engineering drawings for road projects, topographic maps, Engineers’ maps, plat maps, section breakdowns and road establishment documents.

Please note: Due to recent budget cuts, Map and Records Center hours have been reduced to Tuesday-Thursday from 8 a.m. - 4:30 p.m. We are located in the King Street Center Building in historic Pioneer Square in downtown Seattle. View our contact information and driving directions.
