Communication Control Box Improvements Project

Updated June 26, 2019

Environmental Services continues design on a project to modify and install communication control boxes (CCB) in multiple locations throughout Portland. These electrical panels collect flow rates and other information needed to maintain the sewer system (see photo). CCBs can detect problems in the sewer system and alert Environmental Services staff to take corrective actions. As the city upgrades sewer pipes, monitoring points may move and new monitoring points may be added. These improvements will help prevent combined sewer overflows into the Willamette River. Enhancing our system technology protects water quality and public health.

Construction Schedule and Sequence

Communication Control Box Improvements are expected to occur between fall 2019 and spring 2020. Over the life of the project, crews will be coming and going to several sites throughout Portland to complete work in steps (see map below). CCB upgrades will include these steps:

Removal:Communication Control Box Illustration

  • Dismantle outdated electrical box
  • Relocate circuit panel and meter
  • Remove pavement
  • Lay temporary pavement


  • Excavate trench in street
  • Install electrical conduit underground
  • Build electrical panel
  • Permanently pave trench (weather dependent)

Because construction of CCBs requires coordination with public and private agencies, contractors and specialized subcontractors, there will be periods of inactivity between some of these steps ranging from a few days to a few months. 

What to Expect Before Construction

Before construction crews will be in the area from time to time performing land survey, marking utilities, trimming trees and other preconstruction activities. To learn more about preconstruction activities go to website

What to Expect During Construction:

Local Access: Local access to all properties will be maintained, but construction activities may impact or delay normal use of your driveway. Please allow for extra time for our crews to make the area safe before entering or leaving the construction area.

Traffic Delays: You should also expect traffic delays in and near the work area. Please observe traffic control devices and signs, and follow the directions of flaggers if present.

Parking Restrictions: On-street parking will be restricted in and near the work zones to create a safe work environment and to stage equipment and materials.

Equipment Storage: Some equipment and materials may be stored overnight on your street, nearby streets, or other public right-of-way areas.

Noise, Vibration, and Dust: The contractor will use open trench excavation to install electrical conduits underground. This creates noise, vibration, and dust. For more information on open trench, visit

Periods of Inactivity: Work will be conducted in multiple phases. A variety of factors, including conditions underground, weather, subcontractor schedules, and availability of materials may cause periods of inactivity. 

Maintained Service: Water, power, and other utilities are expected to be maintained during construction.
