Hillsdale South Sewer Repair Project

Updated February 3, 2020sign up for email updates

Environmental Services – your sewer and stormwater utility – is beginning construction on the Hillsdale South Sewer Repair Project. The project will repair or replace approximately 7,229 feet of 80-year-old public sewer pipes throughout your neighborhood. Taking these actions now will help protect public health and the Fanno Creek and Tryon Creek watersheds by reducing the possibility of costly breaks, leaks, blockages, and sewage releases to homes, businesses, and streets.

Project Area

The Hillsdale South Project is one of three sewer repair projects planned for the Hillsdale area. Environmental Services is in the early stages of planning and design for the Middle and North sections. A construction date for these sections is not currently known, but it is anticipated that this work will take place following the completion of the South section.

Current Construction Map

Schedule

Crews will be in the project area prepping streets, moving in equipment, and conducting sewer repairs. The schedule below is subject to change due to a variety of factors, including conditions underground, weather, subcontractor schedules, materials availability, and other factors.

Week of February 3:

Crews will be conducting service lateral repairs and spot repairs using open trench excavation to the main sewer line. Spot repairs are small sections of broken sewer pipe that need to be replaced. This will happen at the following location:

  • SW 31st Avenue between SW Miles Street and SW Nevada Street

Week of February 10:

Crews will be conducting service lateral repairs and spot repairs using open trench excavation to the main sewer line. This will happen at the following locations:

  • SW 31st Avenue between SW Miles Street and SW Nevada Street
  • SW 31st Avenue between the intersection of SW Capitol Highway and SW Miles Street

Week of February 17:

Crews will be conducting service lateral repairs and spot repairs using open trench excavation to the main sewer line. This will happen at the following locations:

  • SW 31st Avenue between the intersection of SW Capitol Highway and SW Miles Street
  • SW 32nd Avenue between SW Nevada Court and SW Texas Street
  • Near the intersection of SW 32nd Avenue and SW Miles Street 

Construction Hours

Construction hours are from 7:00 a.m. to 6:00 p.m. Monday through Friday. The contractor may schedule work during the same hours on Saturdays if needed. The Portland Noise Office approved night work for three locations within the project boundaries. Homes and businesses near these locations will receive a separate notification before night work takes place.

Night Work/Extend Hours

The Portland Noise Office granted the Hillsdale South Project a noise variance to enable the contractor to work both days and nights at multiple locations that have high traffic volumes, larger and longer pipes, and construction methods that require extended work hours after 6 p.m. Exact work hours and duration at each location will vary.

You will receive a door-hanger notice a few days before work starts on your street. Please be aware that construction schedules may change due to a variety of factors, including conditions underground, weather, traffic, subcontractor schedules, and materials availability. These same variables may cause periods of inactivity between construction phases.

Construction Methods

This project will include both trenchless and trench excavation methods:

  • Open Trench Pipe Repair: The contractor digs a trench, installs a new pipe, fills in the trench, and restores the street to its previous condition.
  • Pipe Lining (CIPP): Through a manhole, the contractor inserts a flexible liner into the existing pipe.  The liner hardens to seal cracks and form a new smooth pipe.
  • Pipe Bursting: The contractor pushes a bursting head into the sewer line to break apart the existing pipe while pulling a new pipe into place behind it.

What to Expect During Construction

You can expect the following activities and impacts during construction:

  • Traffic Delays: Expect traffic delays in and near the work area.
  • Driveway Access: Construction may temporarily block your driveway when crews are working in front of your property.
  • No Parking: Little or no on-street parking will be allowed in and near work zones, especially during work hours.
  • Equipment Storage: Equipment and materials may be stored on nearby streets overnight.
  • Services Maintained: Sewer, water, and other utilities are expected to remain in service during construction.
  • Assistance: A city inspector will be on-site during work hours and may be able to assist you with an immediate need during construction.
  • Emergency: In the event of a sewer emergency or backup, call the City Maintenance hotline at 503-823-1700; it is staffed all hours and all days.
  • Translation: For translated material about what to expect during construction, please visit www.portlandoregon.gov/bes/constructionimpacts.

Items in the Right-of-Way

Most sewer repair activities during this project will occur in the public right-of-way. It is important that property owners understand that the public right-of-way extends all the way to the property line, and in many cases in SW Portland, what may appear as a front yard or planting strip is actually the public right-of-way. Items located in the right-of-way may be disturbed by construction, including irrigation systems, hard landscaping (stone, concrete, steel, brick, pavers, garden boxes, edging, retaining walls, or other construction materials), soft landscaping (trees, plants, shrubs, flowers, flower beds, grass, bark and the like) and other amenities.

These items will not be restored or replaced if disturbed by construction. However, once construction is complete, they will repair or replace sidewalks and curbs as needed. The city will also replace topsoil and grass seed in the planting strip, and any street trees that were removed. Please remove any items you wish to keep that are located in the right-of-way before construction begins near you.

What We Need from You

Environmental Services is working directly with individual property owners to gather information regarding access issues, private improvements in the right-of-way, and private sewer connections. If you have received one of these notices, please take the time to read and follow the instructions included in these documents. Your input and participation will help us construct a project with maximum benefits and limited impacts.
