Traffic Advisory: Storm Sewer System Maintenance Scheduled Sept. 16-20 in NE Hillsboro

Post Date:09/10/2018 2:39 pm

Residents enjoy healthy local waterways and flood prevention thanks to the City of Hillsboro’s storm sewer system.

City crews will conduct routine storm sewer pipe cleaning and inspection overnight Sunday, September 16 through Thursday, September 20, 2018, from 7 pm to 4:30 am on three roadways. During work, all roads will remain open to traffic.

  • NE 59th Avenue (between NE Evergreen Parkway and Bennett Street)
  • NE Evergreen Parkway (between NE 59th Avenue and Cornelius Pass Road)
  • NE Imbrie Drive (between NE Evergreen Parkway and Cornelius Pass Road): Due to the location of the storm sewer pipeline along NE Imbrie Drive, the road will be reduced to one lane of traffic and controlled by flaggers. The road will re-open to two-way traffic each morning by 4:30 am.

The City’s storm sewer system - composed of 250 miles of underground pipeline, culverts, catch basins, open ditches, streams, creeks, water quality facilities and wetlands – is designed to carry rainfall and other drainage away from homes and businesses and direct it to rivers and streams, which helps prevent localized flooding.

Every four years, the City cleans storm sewer pipelines. At least once every eight years, City crews use specialized camera equipment to inspect and rate the condition of each public storm sewer pipe.

Everyone can help keep the storm sewer system in working order and protect our waterways with a few simple actions:

  • Keep streams and other conveyances that carry rainfall runoff through their property free of obstructions and debris such as trees, tall bushes, and trash. A plugged or obstructed drain cannot carry water and could cause flooding.
  • Never dump or throw anything into the streets or storm sewer system as the system conveys storm water directly to local waterways.
  • Report storm drainage problems or clogged catch basin immediately to the City of Hillsboro Public Works Department at 503-615-6509 or online. For an after-hours storm sewer emergency, contact 503-629-0111.

The City of Hillsboro thanks the community for their patience as this necessary maintenance project is completed. Visit us online to learn more about Hillsboro’s storm sewer system.
