Hillsdale South Sewer Repair Project

Updated August 21, 2019sign up for email updates

Environmental Services – your sewer and stormwater utility – will begin construction in the fall of 2019 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.

Engineers have determined which pipes will be repaired in the Hillsdale South project area, and have also identified construction methods and potential night work locations. To learn more about these construction methods click here.

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.

Schedule

In the next few months, the city will be considering bids for construction and a contractor will be selected. Once a contractor is selected, they will begin developing the overall construction schedule.

Construction is anticipated to begin in November 2019 and take 13 months to complete.

In general, work hours will be from 7 a.m. to 6 p.m. Monday through Friday, and Saturdays as needed. To reduce public impacts and complete the work as quickly as possible, work will also take place at night in several locations.

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.

What's Happening Now

Over the last few months, crews have been in the neighborhood surveying, locating utilities, inspecting sewer pipes and manholes, studying soil types and conditions, and collecting information to help engineers decide which locations need repair and what construction methods are best for each location. You may still see crews in the neighborhood conducting these activities.

These design and pre-construction activities typically occur over time, rather than all at once.

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.

Night Work and/or Extended 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.

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.
  • More Information: More information about what to expect is available online at: www.portlandoregon.gov/bes/constructionimpacts.
