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.
Environmental Services will be constructing sewer repairs on N Mississippi Avenue between Shaver and Fremont to replace over 1,000 linear feet of sewer pipe. This urgent sewer capacity project will replace and upsize a 100-year-old sewer main that is deteriorating due to age and is also too small for the area. The replacement and addition of new larger pipes will increase sewer capacity, reduce basement sewer backups and street flooding, and help protect public health and the environment.
Environmental Services has hired Titan Utilities, LLC. and is scheduled to start construction on January 5, 2021. The project is estimated to take about five months to complete. This schedule is dependent on weather and the ongoing COVID-19 restrictions and may fluctuate. We will provide regular updates regarding the schedule throughout construction.
Environmental Services is coordinating efforts with PBOT’s Healthy Businesses Program. The current Healthy Business permits in the project area expire January 4, 2021, so please be sure to have items removed from the street by that time. There will be 5-minute pickup/drop-off zones on the side streets, but not along N Mississippi within the project area. Sidewalks should remain open for pedestrians. If you have questions or need information regarding the Healthy Business Program email firstname.lastname@example.org.
Two new sections of pipe will be installed to the west of N Mississippi. Approximately 217 feet of new sewer pipe on N Shaver between N Michigan Ave Alley and N Missouri Ave Alley that will connect three properties to the sewer. And, approximately 183 feet of new sewer pipe on N Failing St between N Mississippi Ave to N Michigan Ave that will connect two properties to the new sewer. These two new sewer lines are a part of a separate contract and will likely be installed towards the end of the N Mississippi work by the same contractor. Information about construction and schedules will be provided with the N Mississippi Project updates.
There are two different methods of construction that will be used on this project. Open Trench and Pipe Bursting. Some sewer connections will be dug using a trenchless technology. More information on these methods can be found at www.portlandoregon.gov/bes/methods.
Open Trench Pipe Repair: The contractor digs a trench, installs a new pipe, fills in the trench, and then repaves the filled trench.
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. The contractor then fills in the sending and receiving pits and repaves the filled pits.
Noise, Vibration, and Dust: Construction creates noise, vibration, and dust.
Typical Work Hours: Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, and Saturdays if needed.
Schedule Changes and Inactivity: Construction schedules can change due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials. These same variables may cause periods of inactivity during construction phases.
Traffic Delays: You should expect traffic delays in and near the work area. Please observe traffic control devices and signs.
Parking Restrictions: On-street parking will be restricted in and near the work zones to create a safe work environment.
Equipment Storage: Some equipment and materials may be stored overnight on your street, nearby streets, or other public right-of-way areas.
We will be sending frequent email updates to keep you posted on the construction schedule, and activities, including possible traffic detours, delays, and parking restrictions.
