Poplar Street Pump Station

Starting in the early hours of the morning on Monday, July 8, City contractors delivered and successfully poured concrete for the tank’s 1200+ cubic yard base of the site’s future stormwater storage tank.

(City contractors working to install concrete base of the stormwater storage tank) What’s next?

Stormwater Storage Tank Construction - 10 Poplar Street Site

Crews are currently working to move forward tank construction by preparing for installation of the tank’s concrete walls (see picture below).

Wall installation is expected to proceed through the month of August with a currently anticipated completion date of mid-September.

Work hours for tank installation are typically 7 a.m. to 4 p.m. Some early starts (5 a.m.- 6 a.m. may be required on select dates where concrete delivery/pouring is taking place.

Weather permitting, beginning Monday, July 8 at 2 a.m., City contractors will be delivering and pouring concrete for the 1200+ cubic yard base of the site’s future stormwater storage tank.

The early start will enable operations to proceed efficiently and reduce the daytime impact on neighborhood streets.

What to expect?

During this operation, numerous concrete trucks will be delivering concrete for the tank’s base. Trucks will arrive at the site and queue to deliver concrete to the excavated area.

Anticipated Schedule and Trucking Route (Subject to Change Due to Weather or Other Factors)

The majority of concrete is expected to be delivered between the hours of 2 a.m. to 6:30 a.m. on Monday, July 8th.

Trucks will be routed from Joy Street down Poplar Street to arrive at the project site. Trucks leaving the project site will be routed via Poplar Street to McGrath highway.

Some trucking may be required beyond this timeframe (2 a.m. to 6:30 a.m.). However, all concrete trucks are expected to be out of the neighborhood by 2 p.m. on Monday, July 8.

Additional Construction Impacts:

• Parking restrictions will be in place around work zones

  • Please observe posted signage

• Elevated noise levels in direct vicinity of site during work hours

Thank you for your patience and understanding during this crucial phase of the project’s construction.

Work has progressed over recent months both within the 10 Poplar Street site and under Linwood Street and Poplar Street where associated subsurface utility work is taking place. Below is an update on each of these workstreams as well as upcoming planned detours.

Linwood Street and Poplar Street (Right of Way Work)

• Crews are continuing to install subsurface utilities associated with the Pump Station along Linwood Street and Poplar Street. This work is expected to continue through July.

  • During the duration of this work regular closures will be required on Poplar Street during work hours (weekdays 7 a.m. to 4 p.m.)

  • Alternating, periodic closures of the intersections of Poplar/Linwood Street and Poplar/Joy Street will be required.

    • Crews will work to limit intersection closures to maintain ease of access for residents.

      • We anticipate an approximately ~2 week closure of the Poplar/Joy Street intersection during the first weeks of July. See below for additional info and detour routes.

10 Poplar Station Site Pump Work

Following the completion of excavation for the stormwater storage tank, crews have been working to prepare for the tank’s installation by creating a level surface and installing anchors that will link the tank with underlying bedrock among other efforts.

Next, crews will pour the 1200+ cubic yard concrete slab that will serve as the tank’s base. Additional notification will be provided here and via the City Alert systems ahead of this work.

Poplar Street Pump Station - Progress Update

City contractors have nearly completed digging the 40-ft deep, 170 ft. diameter area hole that will house the Pump Station's underground stormwater storage tank. Once constructed this tank will have capacity to store up to 4 million gallons of stormwater.

After excavation is complete, crews will begin prepping the area for the installation of the tank. These preparations include removing loose native rock, installing anchors that will eventually connect the tank to the underlying bedrock, and adding fill to create a level surface among other activities.

Meanwhile, crews will continue installing underground utility along Linwood Street–requiring a temporary closure of the street. More information included below.

Linwood Street Closure and Detour

Linwood Street will be closed between Poplar Street and McGrath Highway beginning March 4th or soon after.

• Access will be maintained for abutters
• Northbound traffic on Linwood St. will be detoured via McGrath Hwy or Joy St.
• Southbound traffic will be detoured via Joy St.

Please observe posted signage and proceed with caution.

Anticipated Schedule (subject to change):

• Approximate duration of this phase of work is two months.
• Work hours are weekdays between approximately 7 a.m. and 5 p.m.

Construction Impacts:
