Standard Symbol List

All drawings for Seattle Public Utilities (SPU) or Seattle Department of Transportation (SDOT) projects, whether produced by City employees or by consultants, must comply with the SPU/SDOT CADD Standard. The resources available here will answer most, if not all, questions regarding compliance.

The files for download have been prepared for AutoCAD R14, ACAD2000i and ACAD2002. Users of other versions of AutoCAD will not be able to fully utilize the custom menus and routines, but will be able to utilize the blocks, fonts, and templates. ACAD 2002 is currently in use by Seattle Public Utilities.

Disclaimer

These documents are subject to revision without notice. Before starting a new project, download these files to ensure you have the latest revisions.

These standards have been adopted by SPU and SDOT, but not other City departments. If you are producing drawings for another department, check the project requirements before relying on these Standards.
