Reminder: Full Road Closure Starts Next Week

The next phase of work is set to begin on the project! This will result in full (24-hour) road closures in multiple block segments along D Avenue for up to eight weeks.

Drivers, pedestrians & cyclists – please be alert, avoid the closure zones, plan ahead for travel delays and use one of the four open cross streets to access the neighborhood (see below).

Starting the week of July 16, crews will begin implementing the closures in segments. The first segment to close will be from 1st Street to 4th Street. The second segment will be from 4th to 7th, the third from 7th to 10th, and the final segment from State to 1st. Within a week, the entire ten blocks is expected to be closed to all through traffic traveling east/west – including vehicles, pedestrians and bicyclists. North/south access points to cross D will be maintained at most times at 1st, 4th, 7th and 10th Streets.

During the major road work, one crew will excavate the road/existing asphalt and underlying soil, install new structural base rock, and then move up to the next segment. Concrete crews would then arrive to form the sidewalks/valley gutters/curbs, and move onto the next segment. The next activity would include constructing the stormwater planters, then placing the first layer of paving (likely late August). The final activity would be planting the final landscaping, placing the final layer of paving and installing the lighting (in the fall).


At most times during this closure, the contractor will maintain north/south access through the intersections of D Avenue at 1st, 4th, 7th and 10th Streets (see map). However, there will be short-term closures at these intersections while crews excavate the road. 1st Street, between D and E Avenues, will also be closed temporarily (up to three days) during the first base lift of paving.

Access for residents living in the closed areas on D Avenue will be maintained at most times, but there will be periods where driveways are blocked. Crews will work with residents to provide reasonable and safe access to homes while work is occurring.

Access to D Avenue from alleys will be closed—alleys will be barricaded at D Avenue. Neighbors will need to access alleys from E or C Avenue.

Road Reconstruction – What to Expect

Disruption – road reconstruction work is loud, dusty, creates vibration and causes traffic delays. D Avenue will be completely dug-out, re-rocked, regraded, and then repaved. Truck traffic will be coming and going as crews excavate the entire roadway, form concrete and prepare the road for new pavement.

Neighbors have already experienced an increase in dust with the utility work. Unfortunately, this will continue with the road reconstruction work, but crews will be running their water truck regularly to help manage this as best as possible.

Parkingthere will be no on-street parking allowed in the closed areas along the D Avenue right-of-way. Neighbors and visitors will need to park on a side street. Please obey the signage – cars will be towed if they are parked illegally.

Fire and emergency services will always have access to the neighborhood.

Mail, deliveries, and garbage services will be maintained.

We understand how inconvenient and disruptive construction is and we thank you for your patience while we make these important improvements!

Night Work and Water Shutoff – July 26-July 27

Preliminary scheduling shows water service to residences and businesses along 1st Street, between B and D Avenue, and a portion of D Avenue, between State and 2nd Street will be shutoff on the late evening (11 p.m.) of Thursday, July 26 through the early morning (6 a.m.) of Friday, July 27.

The purpose of the shutoff is to connect a new valve to an existing waterline at the intersection of D Avenue and 1st Street as part of the project.

To minimize impacts and inconveniences to both residents and businesses affected by the shutoff, this work will be conducted at night from 11 p.m. – 6 a.m. Crews will conduct as much preparatory work during normal work hours, but night work will result in noise from excavation equipment, truck traffic, movement of steel plates, running a hot saw, a generator and miscellaneous equipment. This work is expected to take one night to complete.

48-hours prior to the shutoff, residents and businesses that are affected will receive a door hanger notifying you of the shutoff event.

Vandalism and Littering

On a disappointing note, the temporary construction trailer located at the 10th Street/C Avenue reservoir site was recently vandalized with dog excrement. In addition, dog owners or keepers have been littering – several bags of dog excrement have been left throughout the reservoir site on multiple occasions.

City Code requires that all dog owners or keepers of dogs promptly remove all excrement or other solid waste deposited by their dog in public spaces.

The City has begun monitoring the site more intensely due to recent vandalism activity. We are also asking neighbors to please keep an eye out and report any suspicious activity to the Lake Oswego Police Department, 503-635-0238.

Interacting with the Construction Crews

Construction is disruptive, impactful and an inconvenience. Crews are trying to conduct the work as efficiently as possible.   For safety reasons, please do not attempt to interrupt their work, nor approach them or their vehicles and equipment within the work zone areas.  It is not safe and it is distracting to the workers, ultimately affecting their efficiency.  If you have concerns or questions about the project, please contact the project team directly and we will address your concerns promptly. This way we keep the area safe, not only for the workers but also for residents and pedestrians.

Thank you for abiding by our continued request to not enter the work zone or disrupt the workers.

General Information

Allowed work hours are 7 a.m. – 6 p.m. Monday to Friday.

Construction schedules change frequently. We will strive to keep residents informed through these regular updates.
