Clinton Green Street and Sewer Project

The Clinton Green Street and Sewer Project is replacing 3,800 feet of sewer pipe installed over 100 years ago, constructing 24 green street planters and adding two blocks of pervious paving.

The new greens streets and pervious pavement will keep 1.8 million gallons of stormwater out of the sewer system annually. These improvements will protect public health, property and the environment, and reduce the possibility of sewage releases into streets, homes and businesses.


Developments of Note

Beginning next week and continuing throughout March, crews will focus on paving areas patched with temporary asphalt

  • Residents adjacent to areas that will be paved will be notified by flyer and on-street parking will be restricted. 
  • Each area requires preparation before paving and there may be a period of inactivity between these steps.
  • Paving may be postponed due to wet weather and rescheduled on short notice to take advantage of subcontractor availability and dry weather.
  • Pervious paving on SE Ivon Street between 20th and 21st avenues and between 21st and 22nd avenues remains on hold and will not occur until after March.

Preparation for sewer construction on SE 30th Avenue between Taggart and Clinton is scheduled to begin next week

  • Crews will begin mobilizing equipment and conducting preconstruction activities such as marking utilities and saw cutting pavement that will be excavated.
  • On-street parking will be restricted as needed to create a safe work zone and for storage of equipment and materials.
  • Sewer construction will begin following saw cutting and is expected to take about four weeks to complete.
  • There may be a period of inactivity between sewer construction and final trench paving.

Sewer construction on SE 35th Avenue between Clinton and Division is expected to be complete in the first week of March

  • There may be a period of inactivity between sewer construction and final trench paving. 
  • Very heavy rains can flood streets, cause sewers to back up into basements, carry pollutants to our waterways, and cause sewage overflows to the Willamette River. The new green street planters work with underground infrastructure to address these issues by capturing and naturally treating storm water before it reaches our streams, rivers, or combined sewer system.
