Construction activities and schedule

King County's contractor began construction at Smith Cove Park in December 2017 and 32nd Avenue West in January 2018. Pipe bursting was completed in early May.  Restoration is underway and expected to be complete this fall. Scroll through the pictures and read the text below to learn more about construction and restoration activities.

Work Areas

32nd Avenue West

The contractor is working to restore the upper diversion structure underneath the street. This structure diverts excess stormwater and wastewater from the City of Seattle’s pipes into the Magnolia Wet Weather system. The contractor will restore the structure and the surface, including the retaining wall, plantings, and areas of pavement affected by construction. You can expect the following from upcoming construction activities:

  • The contractor is working 7 a.m. to 5:30 p.m. during the week on 32nd Avenue West. They may need to occasionally start early to allow for delivery and removal of oversize equipment.
  • Work is generally confined to the diversion structure. Neighbors will notice increased noise when shoring is removed.
  • We will provide advance notice of work outside of regular hours or noisy activities like shoring removal.

  • The contractor is working from 7 a.m. to 5 p.m., as approved by the City of Seattle Street Use Permit.
  • Traffic control will be in place, as shown in the map below, when equipment and workers are in the road. Please watch for signs and flaggers and drive slowly when work is underway.
