Buckman-Kerns Green Street and Sewer Project

Construction type
Sewer and Stormwater
Project status
Active

Environmental Services is designing a project that will install and upsize public sewer pipes, as well as construct green street planters within the Buckman and Kerns neighborhoods. These improvements will increase sewer capacity, relieve sewer backups, and reduce street flooding.

Project design is complete. Construction is now anticipated to begin in June or July 2021 and finish in September or October 2023.

What's Happening Now

Street Trees

Environmental Services is planting 65 new street treesin the Buckman and Kerns neighborhoods as part of this project. Most will be planted inside the green street planters, and some outside in the planting strip.

It will be necessary to remove up to nine smaller trees to build the planters, and two larger trees to build the ADA ramps. The two larger trees are located at the intersections of SE 16th and 17th and Washington.

Environmental Services and the Urban Forester determined the ramps cannot be built without significantly impacting the root system, making it a potential hazard. In addition, the trees are on the nuisance list, and due to their locations, can create a safety issue by prohibiting site lines for vehicles, bicycles, and pedestrians when crossing.

Private Improvements in the Right-of-Way

Crews may need to access and work in the right-of-way--specifically, the planting strip between the curb and the sidewalk--in order to repair, replace, or construct green street planters and sanitary and/or storm sewer pipes. The property owner is responsible for maintaining the portion of the public right-of-way between their property and the curb. This includes caring for permitted trees, mowing grass, and maintaining a safe sidewalk. However, the City retains the authority to use that area on behalf of the public. 

In February and March 2021, properties that will have impacts in the right-of-way during construction should have received a letter. The letter would direct property owners to prepare to remove any items from the right-of-way before crews arrive. Since construction is being pushed out from May to June or July of 2021, there is now more time to prepare to remove any items property owners wish to salvage prior to construction.

Night Work Permit

Portland noise code allows construction from 7 a.m. to 6 p.m. Monday through Saturday. Work after 6 p.m. and before 7 a.m. and all hours on Sundays requires a noise variance from the Portland Noise Office.  

To minimize interruptions to traffic at busy intersections on East Burnside and protect public safety, Environmental Services is proposing to repair sewer lines overnight. The project has requested a permit from the Portland Noise Office to allow night work at four locations in the Kerns Neighborhood:  

  • SE 26th Avenue and E Burnside Street for four nights with open trench excavation. 

  • NE 24th Avenue and E Burnside Street for three nights with cured-in-place-pipe lining (CIPP) trenchless method. 

  • NE 28th Avenue and E Burnside Street for three nights with open trench excavation. 

  • NE 32nd Avenue and E Burnside Street for four nights with open trench excavation. 

Work hours proposed are 9 p.m. to 6 a.m., Monday through Saturday, with no work on Sundays. When possible, work crews will complete louder tasks before midnight. The equipment will include various trucks (water jet, CCTV, vacuum, asphalt and dump), an air compressor, pavement saw cutters, whisper bypass pumps, generators, lights, front end loaders, track hoes, cranes, and pavement roller compactors.

We Want to Hear from You

Please let us know if you have a concern or question about future construction near you. Be sure to include your name, property address, and project name (Buckman-Kerns) in your voicemail and email so we can provide you more details about what to expect in front of your property. Also, please write “Buckman-Kerns” in the subject line of your email.   

Sewer Emergency: In the event of a sewer backup or basement flooding, call the Maintenance hotline immediately at 503-823-1700. It is staffed all hours and all days, 24/7.

Construction Methods

The contractor will use open trench excavation and cured-in-place-pipe lining (CIPP) to construct sewer and stormwater improvements. Most of the mainline public sewer pipes will be replaced with the open trench excavation method.

What to Expect

You can expect the following activities and impacts during construction:  

  • Noise, Vibration, and Dust: Construction creates noise, vibration, and dust, and disrupts normal neighborhood activity.  

  • Equipment Storage: Equipment and materials may be stored on streets overnight.  

  • No Parking: Little or no on‐street parking will be allowed in and near work zones, especially during work hours. On days when crews will be working in front of your house or nearby, please plan ahead. If you park your vehicle on the street, plan to move it off the street by 7 a.m. and return it at 6 p.m.  

  • Traffic Delays: Expect traffic delays in and near the work area. The contractor will develop detailed traffic control plans for each location. 

  • Pedestrian Access: If temporary crosswalk and sidewalk closures are necessary, signage will indicate the alternate way for pedestrians to proceed.  

  • Services Maintained: Sewer, water, and other utilities are expected to remain in service during construction.  

  • Garbage Pickup: Access to garbage and recycling bins for haulers will always be maintained.  

  • 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.  

Project Background

The purpose of this project is to reduce basement sewer backup risk, reduce street flooding, and increase capacity of the large sewer trunk that serves the project area. To that end, this project will upsize or repair portions of the public sewer main line to increase its capacity to handle combined sewer and stormwater. Many of the existing combined sewer pipes are at least 100 to 120 years old and deteriorating. The project will also build green street planters that will help slow, filter, and cleanse stormwater from the streets.   

The project is designed to accomplish the following sewer and stormwater improvements:  

  • Construct 71 green street planters for a total of 15,600 square feet of treatment area. 

  • Replace or repair 23,077 feet of public sewer mainline pipes, ranging in size from 6 inches to 24 inches in diameter.  

  • Construct or replace 480 sewer service laterals that connect private sewer lines to the public sewer in the street; this will involve 9,500 linear feet of six-inch lateral sewer pipes.  

  • Update 106 curb ramps to meet ADA requirements, including 80 individual ramps and 26 ramps that will be modified adjacent to new green street planters. 

  • Construct or replace 150 manholes and 240 storm drain inlets to capture surface runoff.
