CAD Drawings

For the convenience of some of our users, the City is posting the CAD files of all of our Standard Plans for the 2020 edition.

CAD files for Standard Plans that have been amended are located under Amendments on the main page.

All CAD Drawings have been compressed into a zipped folder by series. 

Please contact the City of Seattle’s Construction Standards Engineer at City_Standards_Engineer@Seattle.gov if you have any questions.
