What's Happening Now

SW Vista Avenue Detour Beginning the Week of June 14

Crews will begin construction soon on SW Vista Avenue between SW Buena Vista Drive and SW Hillcrest Drive. SW Vista Avenue is a busy street with no shoulder. Due to the nature of the work and the conditions in the area, crews will need to close SW Vista Avenue to ensure the safety of crews and nearby residents. This road closure will likely last through the end of July. Because a closure is needed to conduct our work safely, a detour will be in place. Emergency responders will have full access if needed. Note: the detour previously scheduled for this area in mid-May was revised based on public input, and work was postponed to June to better accommodate neighborhood requests.

Sidewalks will remain open for people walking, bicycling, and rolling.

Construction Activities and Work Hours    

2500 Block of SW Vista Avenue: open cut excavation pipe repair. This will involve saw cutting and digging a trench in the street to install the new pipe. Crews will also repair a sewer connection from the mainline and install a manhole. 
To minimize disruptions to area residents, work will take place during the day. Work hours are between 9 a.m. to 3 p.m., Monday through Saturday. Crews will place temporary pavement to allow the road to reopen for use when construction is not occurring.

Traffic Detours: 

•    A detour will be in place during construction hours that runs along SW Broadway Drive, SW Ravensview Drive, SW Terrace Drive, SW Elizabeth Street, SW 18th Avenue, and SW Spring Street.
•    The detour allows for TriMet bus line 51, school buses, and delivery vehicles to continue service to the neighborhood.
•    Access to SW Vista Avenue and other roads connecting to it will be maintained, although residents may need to use the detour to go around the road closure, depending on the direction they are approaching from.
 

Please drive slowly, watch for workers in the road, and obey all signs and flaggers.

Patton Road Detour Coming in July

SW Patton Road Detour and Night Work Beginning Week of July 12

Crews will begin construction this summer on SW Patton Road near the intersection with SW Patton Court. SW Patton Road is very narrow at this location, and houses are close to the road. Crews will need to close SW Patton Road at this location to ensure the safety of crews and nearby residents.  This requires a detour to complete our work safely.  Our contractor will work at night, so that traffic is detoured when traffic is light. Emergency responders will have full access if needed.

SW Patton Road Detour Construction Activities and Work Hours

3300 Block of SW Patton Road: open cut excavation pipe repair. This will involve saw cutting in the street as the new pipe is installed. Crews will also rehabilitate a lateral pipeline and install a manhole. The street will place temporary pavement to allow the road to reopen for use during the day.  

Night Work Proposed 

For the safety of neighbors and workers and to minimize traffic impacts on this heavily traveled road during the day, it is proposed that work take place at night. Nighttime work hours are between 6 p.m. - 7 a.m. The loudest activities, such as saw cutting, will take place the earliest, starting at 6 p.m. to minimize disruption to neighbors. Night work is expected to last up to three weeks. 

Noise Reduction Measures 

Crews will use a variety of techniques to help reduce noise at night, including disconnecting backup alarms on equipment, using whisper generators, and installing sound barriers if necessary.  

Submit Comments to Portland Noise Office by June 1st 

Your comments regarding the proposed night work schedule are valuable. You can submit comments to the Portland Noise Office by email at noise@portlandoregon.gov.  

Traffic Detour 

  • A detour will be in place during construction hours along SW Talbot Road and SW Greenway Avenue (see map above). 

  • The detour allows for TriMet bus line 51 and delivery vehicles to continue service to the neighborhood. 

  • Access to Patton Road, Patton Court, and other roads connecting to Patton Road will be maintained, although residents may need to use the detour to go around the road closure, depending on the direction they are approaching from. 

  • Please drive slowly, watch for workers in the road, and obey all signs and flaggers. 

Preconstruction and Other Activities

Parking and Traffic Controls

There may be on-street parking restrictions, lane closures, and traffic delays in and around work zones. Sidewalks will remain open. Access will be provided to all driveways.

Tree Protection

Before construction begins on a street, crews will install tree protective fencing where necessary to protect tree trunks, roots, and branches from damage. The orange fencing will remain in place until construction is completed.

Construction Methods

Environmental Services will use both trenchless and open trench excavation methods for this project. Construction methods are noted on the project map. Some will require digging trenches. Others will replace pipes through manholes or access pits to reduce disruption to the neighborhood. 

Open Trench: The contractor excavates a trench, installs a new pipe, fills in the trench, and restores the disturbed pavement. 

Cured-in-Place-Pipe (CIPP) Lining: Through a manhole, the contractor inserts a flexible liner into the old pipe. The liner hardens, creating a new interior lining. 

More details and photos of construction methods are available.

Cured-In-Place Pipe Lining

Environmental Services plans to use a  trenchless construction method called Cured-In-Place (CIPP) pipe lining in some locations. The CIPP process does not involve digging in the street. It involves inserting a flexible liner inside the old pipe, inflating the liner, and exposing it to heat or ultraviolet light to dry and harden the liner inside the pipe.

During the pipe lining process, residents may smell an odor like plastic or glue. This will dissipate quickly once the process is complete. The odor is from chemicals in the liner resin. The amounts detected by an independent industrial hygienist are below health risk levels.

To keep resin odors from entering a home or business through the private sewer line, 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 a "P-trap," and block odors from the sewer.

If a resin odor is already in a home or business, cover basement floor drains and open windows to allow ventilation. If the odor continues, phone or email the contacts provided on the contractor's construction notice, or call Environmental Services at 503-865-4300 and leave a message with the address, project name, and name and phone number for follow-up.

If you live in a single-family home on a street where crews will be repairing sewer pipe using CIPP, you may be asked not to use appliances that use large amounts of water and to limit flushing toilets as much as possible for one day. You will be notified 24-48 hours in advance if this is necessary. 

To find out more about this process, please visit our CIPP information page.

Open Trench Excavation

Open Trench Excavation is the traditional method of sewer construction and the most common method for replacing a sewer pipe, especially if the original pipe needs to be upsized. It consists of digging down to and exposing the existing pipe, removing the existing pipe or a section of it, installing a new pipe or a section of new pipe, and then backfilling the trench. Learn more about open trench excavation.

Pavement Restoration

Crews will replace and repave the sections of pavement that were disturbed by sewer construction. Crews will remove the temporary asphalt patches they applied over sewer trenches during pipe installation then they will place compacted rock asphalt paving on top of the surface. The broad trenches where crews had to dig in the street will have a fresh new asphalt surface.

Parking and Traffic Controls

There may be on-street parking restrictions, lane closures, and traffic delays in and around work zones. Sidewalks will remain open. Access will be provided to all driveways.

What to Expect During Construction

We want you to be safe around the work site. Please keep children, pets, bikes, cars, and trucks away from the tools, machines, supplies, and construction workers. 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. 

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

Traffic Delays: The work will slow down traffic in your neighborhood. Please read the traffic signs and follow directions from the workers with flags. 

Access to Your Home or Business: You will be able to go to your home or business, but you may not be able to park as close as you would like. We will try to make sure driveways and parking lot entrances stay open. 

Parking Restrictions: We want you to be safe, so you may not be able to park your car next to work spaces, equipment, or materials. If crews are working directly in front of your home or a business, you may need to park in another place. 

Equipment Storage: Sometimes we will leave tools, machines, and supplies on your street overnight. Please stay away from them. 

Maintained Service: You can still use sewer, water, and other services while we work on your street. 

Work Hours: Work hours are 7:00 a.m. to 6:00 p.m., Monday to Friday. Sometimes we work on Saturdays from 7:00 a.m. to 6:00 p.m. 

Schedule Changes and Inactivity: Our work schedules can change for many reasons like weather, traffic, and problems with equipment. 

We Want to Hear From You

We would like to hear from you about special events, school activities, and community services in your neighborhood you think may be impacted by this project. Also, we want to know if you have any concerns related to business operations, disability or mobility issues, medical or business deliveries, and proposed night work. Your input will help us minimize the impact to your neighborhood during construction. 

Call 503-865-6492, stating that Goose Hollow is your area of concern. Outreach staff will return your call by the next business day. You can also email April Hasson with JLA Public Involvement at April@jla.us.com

Project Background

The project scheduled for your neighborhood is part of the city’s program to maintain and upgrade the public sewer system. In the early 1900s, when Portland was growing rapidly, the city built hundreds of miles of sewers. Since most sewer pipes have a lifespan of about 100 years, Portland is now facing an urgent need to modernize our aging system.   

Environmental Services has launched a large-scale effort to repair or replace the highest priority pipes throughout the city. Your neighborhood will experience a temporary disruption but will benefit from the improved infrastructure.  

The city is replacing aging and deteriorating sewer pipes with modern materials. These materials are more resistant to blockages than the materials used 80 to 100 years ago. The updates will provide a safe, efficient, and reliable sewer system for your neighborhood and the city.
