Project Overview

Updated January 2, 2018

Environmental Services has completed the design of the Sunnyside East Sewer and Stormwater Project in the Sunnyside Neighborhood to repair, replace, or install 4,800 feet of sewer pipe. Some of the pipe being replaced is 100 years old and deteriorating due to age. Environmental Services will also add 16 green street planters and replace or plant 26 trees to remove 2.4 million gallons of stormwater from sewer pipes. These improvements will protect public health, property and the environment and reduce the possibility of sewage releases into streets, homes and businesses.

Green streets manage stormwater runoff from streets, add green space to neighborhoods and improve sewer system efficiency. The sewer and stormwater improvements will increase sewer capacity, manage stormwater more naturally, and reduce the risks of street flooding and sewage releases to homes, businesses and streets. Environmental Services installs and maintains the planters, and there is no cost to the adjacent property owners.

Project Map

The project area is generally bounded by SE Oak Court to the north, SE 45th Avenue to the east, SE Taylor Street to the south and SE 38th Avenue to the west.

Design is complete, and construction is anticipated to begin in spring 2018 and take a year to complete.

Construction Methods

Environmental Services will use both trenchless and open trench excavation methods for this project. For the trenchless method, crews dig access pits and insert a guide heath that, when pulled through the pipe, breaks the old pipe apart as it pulls the new pipe into place behind it. Open trench is the most common method of sewer repair or replacement. Open trench consists of excavating down to and exposing the existing pipe so that it can be repaired or replaced and then backfilling the trench. Learn more about these methods at

What To Expect During Construction

Safety is our top priority. You can help keep the area safe by staying clear of all construction activities and keeping children, pets and vehicles out of construction areas.  A city inspector will be on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a hard hat and safety vest with “City of Portland” on the back. For general questions about the project please contact Debbie Caselton at 503-823-2831 or

Noise, Vibration, and Dust: Construction creates noise, vibration and dust and may disrupt normal neighborhood activity.
Traffic Delays: You should expect traffic delays in and near the work area. Please observe traffic control signs and follow the directions of flaggers.
Driveway Access: Local access to your property will be maintained, but construction may impact normal use of your driveway or entrance to your business.
Parking Restrictions: On‐street parking will be restricted in and near the work zones to create a safe work environment and to stage equipment and materials.
Equipment Storage: Some equipment and materials may be stored on your street or nearby streets overnight.
Maintained Service: Sewer, water and other utilities will remain in service during construction.
Schedule Changes and Inactivity: Please be aware that the construction schedule is subject to change due to a variety of factors, including conditions underground, subcontractor schedules, and availability of materials. These same variables may cause periods of inactivity between construction phases.

What Happens Next

Over the next several months, prior to our project, you may see crews surveying, trimming trees, marking and relocating utilities or other preconstruction activities. For more information, go to
