Hollywood-Grant Park Phase 2 Sewer Repair Project


Button. Click to sign up for email updates

The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency. 

Updated December 23, 2020

Construction continues on a project to improve the public sewer system in several Portland neighborhoods. The Hollywood-Grant Park Phase Two Sewer Repair Project includes repair and construction of 3,000 feet of public sewer pipes, 196 feet of sewer service laterals, and several maintenance access holes and sewer cleanouts. These improvements will protect public health and the environment by reducing the possibility of sewage releases to homes, businesses, and streets. 


Sewer repairs are located in various neighborhoods, including Grant Park, Rose City Park, and Beaumont-Wilshire neighborhoods. 

Construction Hours

In general, work hours are from 7 a.m. to 6 p.m., Monday through Friday, and Saturdays as needed. This schedule may change due to a variety of factors, including weather, conditions underground, availability of materials and labor, and other factors.

Look-ahead Schedule for In-between Properties North of NE Wasco Street, between NE 47th and NE 49th avenues

Beginning the week of January 4, 2021, crews will repair sewer mainline pipes, install sewer cleanouts, and repair public service laterals in public sewer easements that are located in-between properties north of NE Wasco Street, between NE 47th and NE 49th avenues.

Construction Methods

Crews will be using the Cured-In-Place-Pipe lining process (CIPP) to repair the sewer mainline and a combination of trenchless and open trench excavation methods to repair and replace public sewer pipes, sewer 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.

Crews will back fill pits or trenches with sand or gravel and compact it before applying temporary paving. Crews will work directly with individual property owners affected by the project to determine what restoration will take place on private property after work is completed.

Details about construction methods are available online at

CIPP Construction Odor

  • When heat (steam) is used to cure or harden the liner during CIPP, people who are nearby may smell an odor that is often described as being similar to plastic or glue. The odor is from the chemical styrene, which is in the resin of the liner. The resin is the part of the liner that reacts with heat and hardens.
  • While unpleasant for some, the amount of airborne styrene generated by the CIPP process is not a health risk at the levels observed by the City of Portland and tested and monitored by an independent industrial hygienist. The odor dissipates quickly once the process is complete.
  • To keep the resin odors from entering your home or business through your private sewer, fill any floor drains and infrequently used sinks with a small amount of water. This water will collect in the bend in the drain called and block odors from the sewer.
  • To find out more about this process, please visit our CIPP information page at
  • If you smell a chemical odor inside your home during pipe repairs or have other concerns related to the odor, please contact Taryn Meyer with our Coordinated Site Analysis Program.
