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 – your sewer and stormwater utility – has started 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. Environmental Services will also build two new sewer lines on N Failing and N Shaver streets. 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.
Work schedules may change due to weather, conditions underground, traffic impacts, subcontractor schedules, and availability of materials. Our contractor will provide notice to residents and businesses near work zones prior to beginning work.
Week of January 18 & January 25:
Crews will begin preparations for Pipe Bursting on N Mississippi Avenue between N Beech and N Fremont streets. Activities include the following:
Week of February 1 activities include:
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.
The city’s contractor for this project has posted NO PARKING signs in and around areas where crews are working and staging equipment and materials. Please do not move or alter in any way the signs and barricades. While we understand that on-street parking is limited in the neighborhood and temporary removal of spaces is inconvenient, the spaces are necessary for crews to do their work. Moving their approved signs can create safety hazards and having to replace them delays their work.
Recently there have been multiple occasions where NO PARKING signs have been vandalized and needed repairs. This has slowed the overall work of the project. If anyone has information about vandalism to these signs, please contact Debbie or Joe (see contact information below).
Some spaces may be posted as NO PARKING during daytime construction hours and open at night. You may park your car in these spaces overnight during non-construction hours if you move your car by 7 a.m. and return it at 6 p.m. Monday through Saturday.
On days when crews will be working in front of your house, nearby, or where you park your vehicle on the street, please plan ahead. Move your vehicle off the street by 7 a.m. and return it at 6 p.m. Monday through Saturday.
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. Please sign up now to receive updates by emailing Debbie.Caselton@portlandoregon.gov or Joe.Tursi@portlandoregon.gov with “Mississippi” in the subject line or signing up at the link at the top of this webpage.
