Hollywood-Grant Park Phase 2 Sewer Repair Project

Updated August 8, 2019Button. Click to sign up for email updates

Environmental Services continues construction on a project to repair or replace 3,000 feet of aging public sewer pipes that are in deteriorating condition. The project includes pipes that were part of the original Hollywood-Grant Park Sewer Repair Project, which was completed in 2017. Due to the complexity of work in sewer easements on private properties, the Phase Two pipes were removed from that project and added to the Montavilla North Sewer Repair Project for construction this summer. The Hollywood-Grant Park Phase Two Sewer Repair Project also includes repair and construction of manholes, sewer access cleanouts, and 196 feet of sewer service laterals. These improvements will protect public health and the environment by reducing the possibility of sewage releases to houses and streets.

Landis & Landis Construction is the City's contractor for the Montavilla North project and the Hollywood-Grant Park Phase Two pipes that are included in that project and shown on the map below.

Location

The project will repair or reconstruct public sewer pipes, manholes, cleanouts, and sewer service laterals at locations illustrated on the map below.

Project Map

General Schedule

Construction in public sewer easements on private properties for Hollywood-Grant Park Phase Two is anticipated to be completed this summer.

Construction schedules may change due to a variety of factors, including weather, conditions underground, soil types, availability of materials and labor, and other factors.

Look-Ahead Schedule

You may have seen crews in the area this week doing potholing to locate sewer service laterals and where they are connected to the mainline public sewer pipe. This activity was in preparation for the Sewer Boring work that will begin the week of August 12.

Sewer boring work is scheduled between properties at the following locations:

  • NE Wistaria Drive east of NE 38th – Laterals August 12-15
  • NE Cesar E. Chavez Blvd north of Stanton St – Laterals August 12-15

What To Expect During Construction

During the sewer boring work to replace service laterals, it will be necessary to dig a sending pit and a receiving pit to install the pipes. Crews will then drill a hole underground between the sending and receiving pits and install the new service laterals without disturbing the surface between the two points.

You can expect the following impacts during sewer boring:

  • Work Hours: From 7 a.m. to 6 p.m., Monday through Friday.
  • Noise, Vibration, and Dust: Sewer boring equipment is especially loud and causes vibration that you may feel in your home.
  • 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 streets overnight.
  • Services Maintained: Sewer, water, and other utilities are expected to remain in service during construction.
  • Site Inspector: A City inspector will be onsite during active construction and may be able to assist you with an immediate need.
  • Emergencies: In the event of a sewer emergency or backup, call the City Maintenance hotline at 503-823-1700; the hotline is staffed all days, all hours.

Pre-Construction Activities

Pre-construction activities may occur throughout the project area to prepare other locations for sewer repair work at a future date. These activities may include locating sewer pipe connections, inspecting and cleaning sewer pipes, marking underground utilities, tree trimming, installing tree protection, installing erosion control measures, staging equipment and materials, and setting up traffic controls. More details are available online at www.portlandoregon.gov/bes/preconstruction.

Construction Methods

The contractor will use a combination of trenchless and open trench excavation methods to repair and replace public sewer pipes, manholes, cleanouts, and sewer service laterals. The methods will vary from property to property depending on many factors, including pipe conditions, soil types, slope, access challenges, and other factors.

Sewer Boring

For sewer boring work to replace service laterals, it will be necessary to dig a sending pit and a receiving pit to install the pipes. Crews will then drill a hole underground between the sending and receiving pits and install the new service laterals without disturbing the surface between the two points.

Cured-in-Place-Pipe Lining

For CIPP lining repairs, crews will use manholes in the street and in between private properties to insert and inflate the lining. The pipe lining process should take one day at each location. Working from a manhole, crews will insert a flexible liner inside the old pipe. Crews then inflate the liner and use hot water, steam, or ultraviolet light to cure the liner, forming a rigid, smooth surface that seals cracks and restores the pipe to near-new condition. Crews will then reconnect sewer service laterals that provide sewer service to adjacent properties. 

Open Trench Excavation

Crews will complete spot repairs using the Open Trench Excavation construction method. Crews will dig a trench to replace isolated segments of the mainline pipe that lining alone cannot adequately repair. Crews will then reconnect sewer service laterals that provide sewer service to adjacent properties. After sewer construction, crews will backfill the trenches and apply a new layer of topsoil and grass seed.

Pipebursting

In locations requiring Pipebursting, it will be necessary to dig a sending pit and a receiving pit to install the sewer pipes. Crews will insert a bursting head into the pit to shatter the existing pipe and force pipe segments into the surrounding soil. Crews will then pull or push new pipe into place behind the bursting head. Crews will then reconnect sewer service laterals that provide sewer service to adjacent properties. After sewer construction, crews will backfill the pits and apply a new layer of topsoil and grass seed.

Private Property Access

Environmental Services and its contractor will continue to coordinate with property owners to plan and schedule access to private properties and public sewer easements. If you have received a Permit of Entry form from Environmental Services, please sign and return it as soon as possible or call us to discuss what is expected to occur on your property.
