Environmental Services is repairing about 40,000 feet (7.5 miles) of public sewer lines in your neighborhood that are between 60 and 100 years old and failing due to age. The project will protect the public and the environment by reducing the possibility of sewage releases to homes, businesses and streets.
Current Construction Activities
Construction crews are working on sewer and lateral pipe repairs. Please be aware that construction schedules are subject to change due to conditions underground, weather, traffic, subcontractor schedules and availability of materials. You will notice several phases as the contractor brings in different equipment or specialized crews at each site.
Sewer repairs upcoming or underway (note: a crew will be working on Saturday, July 11):
NE 57th Avenue between NE Sandy and NE Fremont – Open cut repairs of the main line and laterals are mostly complete. Through July, crews will be installing a few remaining laterals, restoring curbs and driveways impacted by the work, and then repaving the trench areas. Traffic will still be reduced to one lane most days as crews finish the work in the street.
- NE Siskiyou to a half block north of Klickitat – Pipe repair.
- NE 57th between Sandy and Fremont - Staging of equipment and traffic control will extend the work zone.
- Flaggers alternate southbound and northbound traffic in one lane during much of the day.
- All lanes on NE 57th Avenue re-open daily at 3:00 p.m.
- NE Klickitat and NE Siskiyou streets may be closed to NE 57th Avenue at times. Pedestrian crosswalks across NE 57th at NE Klickitat and NE Siskiyou streets will close at times for safety.
- Remaining work in this area is anticipated to be done at the end of July.
- Drivers and bicyclists should expect delays.
- Please follow signage and directions from flaggers for the safety of all.
The contractor is preparing for cured-in-place-pipe lining work on several blocks over the next two weeks, including Saturday.
- Planned dates for cured-in-place-pipe lining are Wednesday, July 8 through Thursday, July 16 including work on Saturday, July 11.
- The process takes about one day per block (from manhole location to manhole location) and requires no excavation. The contractor will notify residents of the exact date of cured-in-place-pipe lining near their home and any special instructions, including limiting water use for that one day. Go to www.portlandoregon.gov/bes/article/467513 for more information about cured-in-place pipe lining.
The following are the remaining locations to be lined this month (locations are approximate and are about one half block to one block in length):
- NE 55th south of Klickitat
- NE 56th south of Hancock
- NE 58th between Klickitat and Fremont
- NE 58th south of Siskiyou
- NE 59th south of Fremont
- NE 60th south of Fremont
- NE 62nd south of Sandy
- NE 63rd south of Sandy
- NE 63rd north of Sandy
- NE 64th south of Sandy
- NE 65th north and south of Klickitat
- NE Klickitat between NE 64th and 65th
- NE 66th north of Broadway
- NE 66th north of Stanton
- NE 67th north of Stanton
The contractor will leave a flyer at your door with the exact date of the lining work and what to expect.
- Pavement restoration on NE 65th Avenue from Tillamook to Hancock, southeast to NE 66th and Broadway (road curves through the Ellington Apartments complex) – Pavement restoration is planned for the week of July 6.
Other activities in the field:
- Pavement is being restored in areas that were disturbed during construction.
- Video inspections of pipe throughout the area occur both before and after repairs.
- You may see small crews at various locations doing one-day pipe lining repairs throughout the area. This requires little to no digging in the street.
What to Expect During Construction
- Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
- Minor tree trimming may occur in the public right-of-way.
- Expect traffic delays. Traffic control signs are set up and flaggers may direct traffic on higher-volume streets. You may see barricades and orange signs reading “ROAD CLOSED to Thru Traffic – Local Access Only.” These signs are intended to reduce overall traffic going through the area while construction is underway but anyone who lives in or needs to conduct business within the construction zone will be allowed access.
- On-street parking in or near active work areas is prohibited during construction hours. Please plan to move your vehicle by 7:00 a.m.
- Equipment and materials may be stored on nearby streets overnight.
- There may be periods of inactivity between construction phases.
- A city inspector is on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a hard hat and a green City of Portland safety vest.
- Please stay clear of all construction activities and keep children and pets out of construction areas.
- You should receive a doorhanger notice a few days before repair work starts on your street. You may notice pre-construction activities like survey or sewer inspections in advance.
Sewer Construction Methods
The city will use a combination of open trench construction and cured-in-place-pipe lining (CIPP). The contractor may use more than one construction method in some areas. For example, the contractor may use CIPP on the main public sewer pipe and open trench construction to repair or replace laterals that connect private sewers from the curb to the public sewer in the street.
There are several phases of open trench construction:
- Saw cut pavement along the width of the trench
- Remove pavement and existing material
- Install public sewer pipe in the street
- Backfill trench with sand or gravel
- Replace laterals that connect private sewers to the system (from the curb to the street)
- Restore surface temporarily with an asphalt patch
- Complete final paving
- Restore other areas disturbed by construction, such as sidewalks, driveway aprons and planting strips
Cured-in-place-pipe lining (CIPP) doesn’t require digging a trench. Work crews access the sewer from manholes to insert a flexible liner inside the old pipe. Hot water or steam inflates and cures the liner, which gradually hardens to form a rigid, smooth surface that seals cracks and restores the pipe to near-new condition. People who live and work near a CIPP repair project sometimes smell a chemical odor during the pipe-lining work. The odor is from the chemical styrene, which is in the resin liner installed inside the pipe. The odor dissipates quickly once the installation process is complete. The amount of airborne styrene produced is not a human health risk. Get more information about CIPP construction.
