Roadway Standards

These Roadway Standards provide the minimum criteria for design and construction of roadways, accesses, site development and integrated drainage facilities under the jurisdiction of Clackamas County. Roadway designs strive to achieve sustainable outcomes when safety, convenience, aesthetics, resource protection, ease of maintenance and community livability are considered.

The purpose of the Roadway Standards is to:

The standards are not intended to limit the creative efforts of engineers in providing alternate solutions to specific problems or relieve the responsibility for professional engineering judgment. Practical designs are encouraged that preserve the function and safety of the roadway system and promote sustainability by offering benefits to aesthetics, resource protection, ease of maintenance and livability.

Clackamas County is interested in comments and suggestions for improvements to the Roadway Standards. Please send any comments or questions to Development Engineering Supervisor Rick Nys at or call him at 503-742-4702.
