OR 217 Auxiliary Lanes - Proposed Sound Walls

Quick Facts

  • Four potential sound walls have been identified in specific locations along OR 217. View the interactive map to see the locations and photo renderings of the proposed sound walls.
  • Sound walls are barriers constructed between the highway and neighboring properties to maximize noise reduction.
  • Construction of each sound wall will be determined by a vote of benefitted residents and property owners.
  • A benefitted resident or property owner is one who lives on or owns a property where noise levels will be reduced by at least five decibels if the proposed sound wall is built.
  • Ballots and additional information were mailed to benefitted residents and property owners in mid-August.
  • The voting period for Wall A has closed. 
  • The voting period for Walls B, C, and D has been extended through October 9, 2019 because less than 50% of eligible voters submitted a ballot for each wall during the first round of outreach.
  • An open house was held on September 10, 2019. Thank you to all who attended.

Background

ODOT’s OR 217 Auxiliary Lanes Project will improve safety and help prevent bottlenecks on a four-mile stretch of OR 217 between Beaverton-Hillsdale Highway and OR 99W. Learn more about the overall project on the project mainpage: www.hwy217.org

As part of the project, acoustic engineers conducted a noise study to determine existing noise levels along OR 217 and what the noise levels will be after construction is complete. The results of the noise study showed that existing noise levels exceed the acceptable range in some locations, and that there will be a small increase in noise levels upon project completion.

When noise reaches a certain level, ODOT assesses the benefits of constructing a sound wall. If the assessment reveals that a sound wall will provide adequate noise reduction based on ODOT and Federal Highway Administration (FHWA) standards, construction of a sound wall is considered. Ultimately, construction of a sound wall depends on the outcome of a vote by eligible property owners and tenants who would benefit from the wall.

About sound walls
The height and length of sound walls is determined by modeling how effective different sizes would be at reducing sound levels. The proposed sound walls along OR 217 could be 10-23 feet tall and multiple blocks in length. Sound walls are constructed between the highway and neighboring properties to maximize noise reduction. The walls are typically made of either concrete post and panel or concrete masonry block. Final type selection will be made later in the project.

Who votes on whether a sound wall is built?

Benefitted residents and property owners are eligible to vote on a sound wall. A benefitted resident or property owner is one who lives on or owns a property at which noise levels will be reduced by at least five decibels if the proposed sound wall is built. These standards are set by ODOT and FHWA. 

How does the voting process work?

ODOT will conduct a vote in August and September 2019. Ballots will be mailed to eligible voters. If 50% or more of the eligible voters submit a ballot, then the votes are counted to determine whether or not a sound wall is constructed. Each benefitted property owner or tenant gets to vote on the corresponding sound wall that benefits their home and/or property.

If the voter response is less than 50%, a second and final round of voter outreach will be conducted. The outcome will be determined by majority vote after the additional outreach, regardless of the final percentage of voter response. A majority of “YES” votes is needed for a sound wall to be built.
