Construction Update 10/19/18

Work on the project has ramped up significantly in the last few weeks. In addition to our primary contractor (Emery), there are as many as five subcontractors working along D Avenue, and periodic visits from PGE crews at any given time.

Crews, each with their own materials and multiple pieces of equipment, are working from one end of the project to the other. For the safety of the workers and the public, daytime block closures will again be implemented along the entire ten blocks of D Avenue. Most N/S intersections will remain open.

  • The closures are limited to daytime working hours (Monday – Friday, 7 a.m. – 6 p.m.).
  • Access for emergency vehicles will be maintained.
  • Access for residents with driveways on D Avenue will be coordinated.

We understand this is an inconvenience, but safety is our top priority and the end is near!

Major Paving Complete!

Earlier this week, crews placed the final top lift of asphalt on D Avenue. 8th and 9th Streets, between D and E Avenues were also paved, along with a portion of 7th Street and 1st Street. There are often circumstances beyond our control that affect construction schedules. Thank you to neighbors for your continued patience and understanding during the changing paving schedule.

Weather permitting, crews plan to pave the alley approaches and remaining driveway approaches mid next week.

New Sidewalk Almost Open!

Crews are progressing well with the new sidewalk. The areas where the sidewalk crosses alleys are being poured today, to allow enough cure time before Republic Services’ garbage collection next Friday. The new sidewalk should be complete by the end of month – just in time for Halloween trick or treating! Although the sidewalk will be complete, landscaping is just getting underway, so watch for open areas and stick to the sidewalk.

The electrical subcontractor is almost complete, and the new bollards will be energized shortly.

Stormwater Facilities and Landscaping

This week, the landscaping subcontractor has been installing irrigation and started placing some of the soil for the rain gardens and stormwater facilities.

Neighbors may have noticed the large excavated areas along D Avenue – these are the stormwater facilities that will eventually be vegetated planters that filter the sediments and pollutants from street runoff, before sending it to Tryon Creek.

These are layered with open graded rock (no fine material) that allows for storage volume. An 18-inch thick layer of planting soil will be placed on top of the rock, followed by the plants. The finish grade of the planters will slope from the road edge to the center of the planter, allowing for appropriate storage and treatment of the runoff.

More than 40 stormwater facilities are being installed along the entire length of D Avenue.

Restoration and Clean-up

Miscellaneous clean-up, restoration and punch-list work will take place over the next couple of months. At this stage, all work is expected to be complete in early January.

Paving Schedule Update

Good news: NW Natural Gas has informed the asphalt plants that natural gas supplies will resume tomorrow morning, allowing for the renewed production of asphalt.  The City’s contractor was able to receive supply preference and paving crews are currently scheduled to pave the portions on 7th, 8th and 9th tomorrow, Friday, October 12.

Due to contractor availability and scheduling demands, crews are not currently planning to work this weekend. Paving is expected to resume on Monday, October 15, and Tuesday, October 16, on D Avenue and a portion of 1st Street.

Normal work hours are 7 a.m. – 6 p.m., Monday to Friday. However, during this critical window of suitable paving weather, extended hours of work will be available to the contractor if needed.

7th Street between C and D Avenue, and 8th and 9th Streets between D and E Avenues, remain closed 24/7 until all asphalt has been placed. The rough subgrade of the road is exposed, and any traffic will damage it. Please obey road closure signs – police are conducting extra patrols.

When crews pave the final lift on D Avenue, rolling block closures will be in place. Watch for flaggers to direct traffic to open roads – please use 10th Street, and E and C Avenues to avoid the paving operation.

A big thank you to neighbors for your patience!

Paving Delay

Due to a significant gas pipeline explosion in Canada, all asphalt plants in the Portland Metro Area were shut-down this morning by NW Natural Gas. Paving crews were unable to receive enough asphalt, which has impacted the paving schedule for 1st, 7th, 8th and 9th Streets, and D Avenue. Crews were originally scheduled to pave today through Friday, but this is on hold as it is unknown when the asphalt plants will be reopened and producing asphalt.

In preparation for final paving, the pavement on 7th Street between C and D Avenue, and 8th and 9th Streets between D and E Avenues, was milled and removed yesterday. The rough subgrade of the road is exposed, and any traffic on it will disturb the subgrade material (shown below). Due to the asphalt delay, these streets will remain closed to all traffic 24/7 until asphalt can be placed.

Given this unforeseen circumstance, work hours may be extended through this weekend – possibly including Sunday – to allow asphalt to be placed on these streets.

We apologize for this inconvenience, and thank you for your understanding in this situation.

Construction Update 10/9/18

Final Paving Starts Tomorrow!

Today, crews are grinding out the old asphalt on 8th and 9th Streets between D and E Avenue, and a portion of 7th Street between C and D Avenues.  The grinding crew is expected to complete their work today, possibly working as late as 8 p.m.

The grinding operation can be messy, as the asphalt is removed and the rough subgrade of the road is exposed. It is not pleasant to drive on and could become quite muddy – these roads will be closed 24/7 until final paving is complete later this week.

On Wednesday, October 10, through Friday, October 12, crews expect to place the final layer of asphalt along the entire ten blocks of D Avenue. Additionally, crews will place 5” of new asphalt in two lifts on 8th and 9th Streets between D and E Avenues, 7th Street mid-block between C and D Avenues, and a small portion of 1st Street near D Avenue.

When crews pave the final lift on D Avenue, rolling block closures will be in place. Watch for flaggers to direct traffic to open roads – please use 10th Street, and E and C Avenues to avoid the paving operation.

During the grinding and paving work, 7th, 8th, 9th and 1st Streets will be closed to all traffic, so the new asphalt can completely cure. There will be no on-street parking on the streets to be paved – while it is always a last resort, cars will be towed if necessary to keep the paving crews moving. Resident driveway access on these streets will be blocked. Alley access will be closed at D Avenue – please use E or C Avenues.

1st, 7th, 8th and 9th Streets, and D Avenue are expected to be back open to traffic the day after the final lift of asphalt is placed.

Neighbors should expect an increase in noise and vibration during the paving preparation and placement. Crews will be using a vibratory roller to compact the rock and newly placed asphalt, which creates vibration. This is a standard piece of equipment that is used throughout the paving industry.

State Street Lane Closure – Now Open

Due to unforeseen circumstances, the State Street lane closure was extended through this morning to allow the new pedestrian ramps time to cure and pavement to cool. Good news – the lane is now back open. Thank you to everyone for your patience during this temporary closure.

D Avenue between State and 1st Street remains closed through early next week while crews finish installing catch basins and prepare for final paving.

Sidewalk Pours Continue

Crews have started pouring new sidewalk along portions of D Avenue. Concrete crews are currently pouring sidewalk near 8th Street, working their way east.

Check out this video of crews pouring new sidewalk last week on D Avenue in between 4th and 5th Street.

New sidewalk will be poured on the north side of D Avenue between 10th and 5th Streets, and on the south side of D Avenue from 5th to State Street. This work is expected continue through this month.

When the forms are placed for the new sidewalk and the concrete is poured, nearby alleys and driveways will be barricaded and closed at D Avenue to allow the concrete time to cure. During this time, residents who take driveway access on D Avenue will need to park on a side street. If you need to enter or exit the alleys, please use E Avenue or C Avenue. To ensure garbage collection is maintained, sidewalk pours across the alleys will be coordinated with Republic Services’ schedule.

If you live on D Avenue and your driveway will be impacted, you will receive a door hanger notifying you of the upcoming closure dates. Please plan to move your car(s) out of the driveway before 7 a.m. on the day the forms are installed, and park on nearby a side street until the concrete has cured.

Thank you for your understanding and patience!

Saturday Work 10/6 & State St. Lane Closure Extended

Concrete crews are busy forming and pouring the new sidewalk and ADA pedestrian ramps along D Avenue. In order to stay on schedule, crews plan to work on placing forms tomorrow, Saturday, 10/6 along D Avenue. Saturday work hours are 8 a.m. to 6 p.m.

State Street (Hwy 43) Lane Closure – Extended through 10/9

Yesterday afternoon, crews hit a gas line at the corner of State Street and D Avenue, which impacted the paving and concrete schedule for this intersection. Due to this unforeseen circumstance, the State Street lane closure has been extended through Tuesday, October 9.

We apologize for this inconvenience and thank you for your patience as we continue to progress with this work.
