Updated May 4, 2017

Sign UP! for emails

Environmental Services will be constructing a project to replace an aging culvert on Fanno Creek at SW 45th Avenue. The new larger culvert will improve stream flow and allow fish to pass through. Two green street planters will also be constructed along SW 45th to capture and filter stormwater runoff before it flows into Fanno Creek. The restoration work and fish passage will continue Environmental Services efforts to improve conditions in Fanno Creek.

Construction Schedule

Construction is tentatively scheduled to begin mid-June. The entire project should be completed by the end of December. The work in the creek must be done during the required in-water work window of July 15 to September 30.

Road Closure

SW 45th Avenue will be closed all hours and all days for one continuous period of up to six weeks to remove and install the new culvert, and for repaving. For all other work, SW 45th Avenue will be closed during work hours only. Work hours are from 7:00 a.m. to 6:00 p.m., Monday through Friday, with the option to work on Saturdays. 

 The closure will be on SW 45th between SW Lee and the Woods Apartments (4940-4950 SW 45th).  The recommended detour is SW Shattuck Road and Hamilton Street.

 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.
  • You should expect traffic delays in and near the work area. Please observe traffic control signs and follow the directions of flaggers.
  • On‐street parking will be restricted in and near the work zones to create a safe work environment and to stage equipment and materials.
  • Some equipment and materials may be stored on your street or nearby streets overnight.
  • There may be periods of inactivity between construction phases due to a variety of factors including weather, subcontractor schedules, and availability of materials.
  • 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.
