Please read the Stakeholder Notice of Proposed Rulemaking Action for information on the process and time frames for review and submitting comments and how to submit comments.

Comments must be submitted no later than 5:00 p.m. on Wednesday, February 12, 2020. After we have reviewed all comments the County Engineer may approve the proposed amended rule(s) in whole or in part, with or without changes, or repeal the proposed amended rule(s) entirely. Once that is done we will provide (email and publish in the Herald) a Notice of Rule Adoption identifying all the sections and standard drawings being adopted. The emailed notice of adoption will also include the final version of the changes.

Please email all your questions, comments, or proposed changes to Erik Olson or Ryan Peterson.
