Hollywood-Grant Park Sewer and Stormwater Project

Button. Click to sign up for email updatesEnvironmental Services began construction in October 2015 on the Hollywood-Grant Park Sewer and Stormwater Project at more than 80 sites. Over the next year and a half, this project will repair or replace 38,000 feet (about 7 miles) of public sewer pipes that are between 75 and 110 years old and in poor condition. The work includes constructing 12 green street planters and six sumps that will remove more than 1.2-million gallons of stormwater from the sewer system annually. These improvements will protect public health, property and the environment, and reduce the possibility of sewage releases into streets, homes and businesses.

What to Expect During Construction

  • Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
  • Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.
  • There will be night work at various locations on this project, you will be notified prior to the start of any night work.
  • Please stay clear of all construction activities and keep children, pets and vehicles out of construction areas.
  • Traffic control signs are in place. The contractor maintains local access, but you should expect delays.
  • On-street parking in or near the work area may be limited. Please observe no parking signs.
  • Equipment and materials may be stored on nearby streets overnight.
  • A city inspector is on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a hard hat and safety vest with “City of Portland” on the back.

There will be periods of inactivity between construction phases.

Construction Methods

The contractor will use open trench construction, pipe bursting and cured-in-place pipe lining to repair sewers. Go to for more information about sewer construction methods.
