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

Sewer construction on SE 36th Avenue between SE Clinton and Division streets will begin following preconstruction activities

  • For the rest of this week, crews will continue mobilizing equipment and conducting preconstruction activities, such as marking utilities and saw cutting pavement.
  • Once preparation is complete, main public sewer pipe, manhole, and lateral construction will begin. This work is expected to take four to six weeks with possible periods of inactivity between phases. 
  • On-street parking will be restricted as needed to create a safe work zone and for storage of equipment and materials.

Green street planter construction will periodically delay northbound traffic on SE Cesar Chavez Boulevard at Ivon Street for several days beginning next Monday

  • Crews are scheduled to construct green street planters on the northeast and southeast corners of SE Cesar Chavez Boulevard and SE Ivon Street.
  • This work is expected to take several days and will periodically close one northbound lane on SE Cesar Chavez Boulevard from 9:00 a.m. to 3:00 p.m. Monday through Friday. The contractor may schedule work on Saturdays during the same hours.

Construction of two green street planters on SE 34th Avenue at Clinton Street is scheduled to begin next Monday

  • Traffic control will be in place as necessary to create a safe work zone.  Vehicles and bicyclists may experience periodic delays for several days. 
  • Please observe traffic control signage and follow flagger directions.

Pervious (porous) paving on SE Ivon remains on hold

  • Pervious paving on SE Ivon Street between 20th and 21st avenues and between 21st and 22nd avenues is postponed until further notice.
  • Additional information will be provided as it becomes available. 

Completed green street planters on SE Ivon now have vegetation and are fully functional

  • 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.
