We are updating the Multnomah County Road Rules (MCRR), and we want to know what you think.

What are the Road Rules?

Our Road Rules are the basic rules for how we manage our roads. They are used in combination with Multnomah County Code (MCC) and our Design and Construction Manual (DCM). They provide administrative guidelines for county roads, including use of county right-of-way.

The Road Rules are also used as "Street Standards Rules" by Land Use Planning. They are one of the tools that set standards for street design and improvements.

What's changing?

The proposed amendments include:

  • Housekeeping updates –formatting changes that make the rules more accessible and easier for customers and staff to navigate.
  • Technical updates – several references are outdated.
  • New updates – new sections that reflect changes in the transportation planning and engineering field.

Highlights of the proposed amendments include:

  • New provisions to address development setbacks from the Willamette River Bridges (i.e. Hawthorne, Burnside, Broadway, Sellwood, Morrison, and Sauvie Island); see Section 25.
  • New provisions are added to address stormwater and drainage, and provide standards for stormwater management and impact to county facilities; see Section 26.
  • New provisions to dealing with the administrative and permitting processes for two programs that occur within County roadways: (1) the Adopt a Road Program, and (2) the Owner Vegetation Maintenance Program; see Sections 23 and 24.
  • Amendments to the glossary to reflect a 2008 MCC update that included road-related definitions; see Section 3.
  • Clarifications to sections of MCRR related to possible requirements for roadway improvements and engineering review; see Section 6.
  • Revisions to sections related to access points were amended to provide clear criteria for when a property owner may seek a second access without requiring a Road Rules Variance; see Section 16.
  • New development requirements for Local Access Roads based on the number of houses located on the Local Access Road; see Section 11.
