Preliminary Work Continues
Emery and Sons Construction Group (Emery) crews have started mobilizing equipment and installing tree protection fencing (shown below) in the right-of-way throughout the project area. This will continue over the next day or so.
Tree protection fencing is required by city code to be installed around trees that are 5-inches or larger in diameter.
Also this week, erosion control and work zone fencing will be installed throughout the work zone on D. These measures will help prevent sediment from washing off the project and clearly delineate the active work area (or “extent of work”) that is expected to be disturbed during construction. Crews will also be installing a 40 ft. long construction trailer at the reservoir site on the corner of C Avenue and 10th Street.
No excavation work or tree removal work can begin until all of the tree protection and erosion control measures are in place, inspected and approved.
Starting tomorrow, Wednesday, May 8, crews expect to begin removing the 49 trees located in the right-of-way which are permitted for removal. Trees will be chipped on-site using a large chipper truck, and hauled off-site for recycling and reuse. Neighbors should expect to see and hear a large chipper truck and crews using chainsaws. Temporary block closures will be in place as crews move through the corridor along D.
The tree removal work is expected to last about two weeks. During this time, crews will also trim tree branches that are overhanging into the right-of-way in areas where the contractor needs additional clearance.
Smaller shrubs and landscaping that is slated for removal and located within the active work area on D will also be cleared and removed. Please note, in March, letters were sent to every property owner along D outlining the extent of work and notifying owners to relocate or move any landscaping or improvements before construction starts.
In preparation for the major utility work, crews will also begin saw-cutting parts of the roadway in the project area.
NW Natural Gas Relocation Continues
NW Natural’s gas relocation work has been progressing slower than originally anticipated. As a result, Emery is now having to shift their work plan, as most of NW Natural’s relocation work needs to be completed before a lot of the major City work to take place along D Avenue.
We continue to coordinate with NW Natural. For concerns or questions regarding this work, including potential temporary gas service shut-offs, please contact Rich Girard on 503-226-4211 or firstname.lastname@example.org.
Emergency Water line Repair Postponed
After uncovering all existing utilities in the intersection at D Avenue and 8th Street city crews discovered that the existing storm line is located closer to the connection point of the water line that needs to be repaired. This means they will have to postpone the repair until after the new storm line is installed and the old storm line is removed from service.
Major Utility Work Starts May 14
Emery plans to have two main crews working throughout the project duration, now starting on Monday, May 14.
The first crew is set to begin on 1st Street at the intersection of D, installing a new storm line and manholes at the intersection then new water and storm pipes up the length of 1st Street to E Avenue. This work is expected to take about three-four weeks to complete.
While crews are working in the intersection, D Avenue will be closed to through traffic between State Street and 2nd Street and 1st Street will be closed between C Avenue and E Avenue. Once crews progress through the intersection, D Avenue will be reopened at State Street.
There will be some minor anticipated water service interruptions (temporary shut-offs for 1 hour approx.). These will take place on 1st Street when crews switch over the water services to the new line. Impacted neighbors will be notified in advance via a door hanger.
The second crew is set to begin at 4th and D (near the library), installing a new storm line and manholes, and then working towards 5th. Work in this area is expected to take about a week, then crew 2 will likely shift to 7th Street (at B), to install a new storm line. This is dependent on NW Natural’s progress.
During the work near the library, please watch for signage and flaggers to safely navigate through the intersection. D Avenue will be closed to through traffic between 4th and 5th Street. There will also be no on-street parking allowed.
Overall Work Plan (*subject to change!)
The estimated duration for Emery’s underground utility work is about 6 weeks, however, this is subject to NW Natural’s progress. Daily road closures will be in place in the work zones during the majority of the big pipe work. Roads will be open after work hours during the utility work.
Once all the underground utility work is done, the major road reconstruction work will begin and this will result in full (24/7) rolling road closures. For this work, crews expect to start on D Avenue at 1st Street and work west to 10th, then loop back to do the block between State and 1st.
During the major road work, one crew will excavate the road/existing asphalt, rock it back, 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 be constructing the stormwater planters, then paving (likely late August). The final activity would be planting the final landscaping and installing the lighting (in the fall).
Full road closures will be needed along D Avenue in order for crews to conduct the work in a phased approach. Emery expects the full closures to be in place for 6 – 8 weeks (possibly starting in mid-late June). During this period, the contractor will maintain north/south access through the intersections of D Avenue at 1st, 4th, 7th and 10th (refer to road closure map below). The work in the intersections will require flagged traffic at that time.
Residents located in the closure zones will be notified in advance of the full road closures via a door hanger, along with the email updates and website posts.
Neighbors Meet the Contractor
About 20 neighbors came along to meet Emery and Sons Construction Group on April 26 at the Adult Community Center. Thanks to everyone for attending on such a bright and beautiful sunny evening! A summary of the meeting is now available on our ‘materials’ page. Please review the summary for more details about what was presented and questions asked during the meeting.
Allowed work hours are 7 a.m. – 6 p.m. Monday to Friday.
With all the work taking place in the neighborhood, please be alert, drive safely, choose another route or plan ahead for travel delays.
As noted, construction schedules change frequently. We will strive to keep residents informed through these regular updates.
