N Skidmore Sewer Extension Project

Updated: April 10, 2017

Construction Begins April 17, 2017

Environmental Services, the city’s sewer and stormwater utility, is extending the public sewer system to properties where service is only available through a neighboring property. This is most commonly referred to as a party sewer connection. Under N Skidmore Terrace, this project will install 540 feet of main line sewer pipe, three new manholes, and branch connections to ten properties allowing them to make direct connections the public sewer. This project will help protect public health, water quality, and the environment.

Sewer construction will begin the week of April 17 crews will begin mobilizing materials and equipment to the work zone. Other activities will include: installation of erosion and traffic controls, and tree protections. The week of April 25, crews are scheduled to pothole for utilities, lay out the boring path and excavate the first boring pit.

HORIZONTAL DIRECTIONAL DRILLING

N Skidmore Terrace is a narrow street, and traditional open trench construction would significantly limit the ability of drivers to use the road during construction. In order to increase driver access during construction, crews will use a trenchless method called horizontal directional drilling or directional boring. Crews will excavate three pits, one entrance pit at each end of the block to launch boring and pipe installation equipment, and one receiving pit between the entrance pits to receive the equipment and new sewer pipe. Manholes will also be constructed to allow for future maintenance activities. To learn more about the horizontal directional drilling method, visit our webpage at: www.portlandoregon.gov/bes/methods.

WHAT TO EXPECT DURING CONSTRUCTION

  • Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
  • Local access to all properties will be maintained, but construction activities may impact normal use of your driveway or entrance to your business.
  • You should expect traffic delays in and near the work area. Please observe traffic control signs and follow the directions of flaggers.
  • Some equipment and materials may be stored on your street or nearby streets overnight.
  • A city inspector will be on-site during work hours and may be able to assist you with an immediate need during construction.
  • Sewer, water, and other utilities will remain in service during construction.
