Computer Aided Drafting and Design (CADD) standards

The King County Road Services Division has developed a Computer Aided Drafting and Design (CADD) Standards Manual and CADD Engineering Drawings for use by CADD users in the division, as well as consultants who are working on projects for the division.

The CADD Standards Manual provides standards and guidelines for creating civil and structural engineering plans and documents for all construction projects within the division. The manual is currently in the process of being updated. In the meantime, please use 2015 CADD Standards for design development.

The 2015 CADD Standards .dwg figures can be accessed here: Figures.zip file (3MB).
