This new infrastructure will help control stormwater runoff during heavy rain events, improve water quality, and help prevent basement and sewer backups.

Construction will temporarily restrict some travel lanes and sidewalk crossings in work zones, remove on-street parking, and create traffic delays.

What are Sumps and Sedimentation Maintenance Holes?

A sump maintenance hole (sump) is a large, concrete cylinder installed under a street and that is connected to a storm drain and a separate tank, called a sedimentation maintenance hole, that filters out garbage and pollutants.

Environmental Services owns, operates, and maintains 8,625 sumps and 6,352 associated sedimentation maintenance holes all over the city.

We Want to Hear from You

We would like to hear from you about special events, school activities, and community services in the neighborhood that you think may be impacted by this project. Also, we want to know if you have any concerns related to business operations, disability or mobility issues, medical or business deliveries. Your input will help us minimize construction impacts to your neighborhood. 

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.

Construction Methods

The contractor will require excavating trenches, accessing manholes, digging pits to complete sump repairs and replacements. 

  • Open Trench Excavation: The contractor excavates a trench for sump repairs and replacements, and then fills in the trench and restores the disturbed pavement. 

What to Expect

You can expect the following activities and impacts during construction: 

A Safe Work Site: We want you to be safe around the work site. Please keep children, pets, bikes, cars, and trucks away from the tools, machines, supplies, and construction workers. 

Noise, Vibration, and Dust: Construction creates noise, vibration, and dust and disrupts normal neighborhood activity. 

Traffic Delays: The work will slow down traffic in your neighborhood. Please read the traffic signs and follow directions from the workers with flags. 

Access to Your Home or Business: You will be able to go to your home or business, but you may not be able to park as close as you would like. We will try to make sure driveways and parking lot entrances stay open. Crew members can help you safely enter or exit your driveway or business parking lot.   

Parking Restrictions: We want you to be safe, so you might not be able to park your car next to work spaces, equipment, or materials. If crews are working directly in front of your home or a business, you may need to park in another place. 

Equipment Storage: Sometimes we will leave tools, machines, and supplies on your street overnight.  

Maintained Service: You can still use sewer, water, and other services while we work on your street. 

Work Hours: Work hours are 7 a.m. to 6 p.m., Monday through Friday. Sometimes we work on Saturdays from 7 a.m. to 6 p.m. 

Schedule Changes and Inactivity: Work schedules can change for many reasons like weather, traffic, and problems with tools, machines, or supplies. Sometimes we need to stop between different types of work and start again later.
