2614-04 Seattle (Wash.). Engineering Dept. Engineering Department R.H. Thomson Freeway Records 1958-1977 5.8 cubic feet 7 boxes Engineering and property records concerning a proposed freeway in Seattle. Collection materials are in English Historical Note

The Seattle Engineering Department (SED) maintained the City's streets and bridges, designed and oversaw construction of public works projects, provided traffic and transportation planning, and operated the sewer and solid waste utility. The position of City Surveyor was created in 1873 to survey the City, establish boundaries and street grades, and administer condemnation processes. This position was renamed City Engineer in 1890.

In 1931, the Engineering Department absorbed part of the Department of Public Utilities, and in 1936, it assumed the responsibilities of the Department of Streets and Sewers and the Traffic Department. In 1997, the water, solid waste, drainage, and wastewater utilities from the Engineering and Water departments were merged with the Engineering Services Division of SED and the Customer Service Call Center and Construction Engineering Sections of City Light to form Seattle Public Utilities. The traffic and transportation functions of the Engineering Department were consolidated in the Seattle Transportation Department.

Reports, surveys, correspondence, meeting minutes, presentational material, photographs, maps court papers, and property appraisals relating to R. H. Thomson Freeway planning. Subjects addressed include earthquake studies, routes, a tunnel under Union Bay, property acquisition and management, the Arboretum and City Council hearings. The freeway was begun but never finished.

Arranged into four series: Correspondence, Reports and Surveys, Court Section Files and City Council Hearing Transcripts.

Records are open to the public.
