Oregon Revised Statute Chapter 368.910 and Clackamas County Code Section 7.03.090 state that property owners are responsible for maintaining sidewalks adjacent to their properties in a manner that is free of potential hazards, including cracks and vertical displacements. 


Clackamas County Code, Section 7.03.090 and Clackamas County Roadway Standards, Section 240 prohibit road impediments and inadequate intersection sight distance. This is meant to prevent potential road use safety hazards which may not provide adequate sight distance to motorists.


Typically, the county posts No Parking signs for one of the following reasons: 

  • The Fire District has reported that on-street parking interferes with the ability of fire vehicles to reach a location in an emergency or;
  • One hundred percent of residents have signed a petition expressing their support for restricting parking.

To request a review of parking, contact our team using the Road Concern form.


We encourage records requesters to use the Public Records Request form.
