Environmental Services will begin construction on a project to extend the public sewer system on NE Flanders Street between NE 66th and NE 67th avenues. This work will provide service to properties currently served by a nonconforming sewer an independent and direct connection to the public sewer.
The project is located on NE Flanders Street between NE 66th and NE 67th avenues.
What's Happening Now
Work crews will periodically be in the area to perform pre-construction activities. Activities include site visits and evaluation, survey, utility locates, and tree trimming.
Some investigative activities will require restricting parking and closing travel lanes. The traveling public should expect minor traffic delays.
We Want to Hear from You
Environmental Services will inform residents about project activities and respond to questions and concerns in a timely manner.
Sewer Emergency: In the event of a sewer backup or basement flooding, call the Maintenance hotline immediately at 503-823-1700. It is staffed all hours and all days, 24/7.
Crews will use Open Trench Excavation to complete all work. Open Trench Excavation is the traditional method of sewer construction and the most common method for replacing a sewer pipe, especially if the original pipe needs to be upsized.
Open trench excavation consists of digging down to and exposing the existing pipe, removing the existing pipe or a section of it, installing a new pipe or a section of new pipe, and then backfilling the trench.
The work includes the following steps:
Sawcut pavement and dig trench to install mainline sewer pipe
Sawcut pavement and dig trenches from the mainline to the curb to install sewer service laterals that connect properties to the public sewer
Install new mainline sewer pipes and laterals
Cover open trenches with steel plates at the end of each day as needed while work is in progress
Backfill trenches with sand or gravel and apply temporary asphalt patches
Conduct quality control inspections
Complete permanent pavement restoration of patched trenches after work passes inspections
Repair any curb and sidewalk panels damaged during construction
Restore any vegetation disturbed during construction with top soil and grass seed
What to Expect
You can expect the following activities and impacts during construction:
Safe Work Site: Safety is our top priority for every construction site. Stay clear of all construction activities and keeping children, pets and vehicles out of construction areas.
Maintained Service: All utilities will remain in service during construction.
Noise, Vibration, and Dust: Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
Local Access: The contractor will maintain local access to all properties, but construction may impact normal use of your driveway or entrance to your business. Please observe traffic control signs and follow the directions of flaggers.
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 your street or nearby streets overnight.
Typical Work Hours: Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.
Schedule Changes and Inactivity: Schedules may change, and you may see periods of inactivity during construction due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules, and availability of materials.
