SE Elliott-Spruce Alley Sewer Project

Sewer and Stormwater
Environmental Services is completing construction in the Ladd’s Addition neighborhood to replace the public sewer pipe in the Elliott-Spruce Alley between SE 12th Ave and SE Birch St. 
Construction began in early August 2021 and will continue through to November 2021.

Project Area

The map below illustrates where this project is constructing sewer improvements. The SE Elliott-Spruce Alley Sewer Project is replacing approximately 650 feet of public sewer pipe that is located between SE 12th Avenue and SE Birch Street.

General Schedule

Construction should be complete in mid-November. Approved work hours are 7 a.m. to 6 p.m. Monday through Saturday.

Look-Ahead Schedule

Crews have completed most of the sewer construction on SE 12th Avenue, moving northeast up the SE Elliott-Spruce Alley towards SE Birch Street. Locations in the alley will be described from property address to address. Over the next several weeks, crews are scheduled to work on minor sewer connections and street restoration at the following locations:

SE Elliott-Spruce Alley from back of 2260 SE Spruce Avenue and 2313 SE Elliott Avenue towards SE 12th Avenue – Week of October 18:

  • Prepare and pour concrete of entire width of alley. The concrete will need up to 28 days to cure and cannot be driven on for up to 10 days.

SE Elliott-Spruce Alley behind 2335 SE Elliott Ave – October 20:

  • Install Cured-in-Place-Pipe Lining (CIPP) sewer connection.
  • CIPP is a trenchless method of sewer construction. This CIPP method will use an ultraviolet (UV) method that doesn’t emit odor. It requires little or no digging. For more information on CIPP, visit

SE Elliott-Spruce Alley at SE 12th Avenue – Week of October 25:

  • Prepare are pour concrete driveway and ADA ramp.

SE Elliott-Spruce Alley from back of 2260 SE Spruce Avenue and 2313 SE Elliott Avenue towards SE Birch Street – Week of November 1:

  • Prepare and pour concrete of entire width of alley. The concrete will need up to 28 days to cure and cannot be driven on for up to 10 days.

The look-ahead schedule is approximate, and the dates of activities may change due to weather, conditions underground, subcontractor schedules, materials and labor availability, and other factors.

Garbage Pickup

Portland Disposal & Recycling (PD&R) will continue to provide garbage and recycling service on Mondays. PD&R will pick up garbage and recycling in front of your homes on SE Elliott Avenue, SE Spruce Avenue, SE 12th Avenue and SE Birch throughout the project.

Vibration Monitoring

Sewer construction causes noise, vibration, and dust. This project includes construction that is close to some structures and in a narrow alleyway. Residents will hear the pavement demolition and sewer installation activities and will feel the vibrations associated with these activities. However, none of these activities is expected to cause damage.

Vibration monitoring is being installed along the entire alley in the right-of-way, as well as on some structures and within properties that have given permission. Crews will monitor the vibration sensors and collect data during periods when there is no activity and when there is construction activity. This will enable them to compare construction vibration data with non-construction vibration sources.

How to prepare for vibration and construction

If you have a concern about any items or features inside your house or other structures that you think might be vulnerable to construction vibration, we recommend that you secure them before construction begins at your property. Secure hanging items like photos, china dishes, or ceramics, or remove them temporarily before construction begins. Items on shelves may rattle and move, so take precautions you think are necessary. We also recommend that you take photos and/or videos to document pre-existing conditions inside your house, including existing cracks on ceilings, walls, and floors. Be sure photos and videos are date-and-time-stamped for verification. 

We Want to Hear from You

We will be sending periodic project email updates on the project progress. Please call if you have concerns or questions regarding the project. Be sure to include your name, property address, and project name (SE Elliott-Spruce Alley) in your voicemail and email so we can provide you more details about what to expect near your property. Also, please write “SE Elliott-Spruce Alley” in the subject line of your email.

What to Expect During Construction

  • Safe Work Site: Safety is our top priority for every construction site. Please stay clear of all construction activities and keep children, pets, and vehicles out of construction areas.
  • Noise, Vibration, and Dust: Construction creates noise, vibration, and dust and disrupts normal neighborhood activity. 
  • Traffic Delays: You should expect traffic delays in and near the work area. Please observe traffic control signs and follow the directions of flaggers.
  • Local Access:The contractor will maintain local access to all properties and driveways, but the alley will be closed during work hours. The alley will be accessible after hours from each end. No through traffic will be available.
  • Parking Restrictions: On‐street parking will be restricted in and near the work zones to create a safe work environment and to stage equipment and materials.  
  • Equipment Storage: Some equipment and materials will be stored on nearby streets overnight. 
  • Maintained Service: Sewer, water, and other utilities are expected to remain in service during construction. 
  • Typical Work Hours: Typical work hours are 7 a.m. to 6 p.m. Monday through Friday. The contractor may schedule work during the same hours on Saturdays.  
  • Schedule Changes and Inactivity: Construction schedules can change due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules, and availability of materials. These same factors may cause periods of inactivity during construction phases.
