Elliott Bay Seawall Early Work Continues

Early work for seawall construction on the waterfront continues this week on Alaskan Way, between Virginia and Pike streets.

What’s New?


Underground utility location, also known as “potholing”

On Monday, April 15, survey and data collection activities commenced adjacent to Waterfront Park to collect information from the seawall monitoring equipment installed in November 2012. This is the fifth of six successive monthly visits. The data is being used to help better understand the existing seawall as we prepare for construction in fall 2013. Monitoring thus far indicates little to no movement of the seawall structure in any single direction. Details of the work include:

  • Work will be conducted on the sidewalk adjacent to Waterfront Park, just south of the Seattle Aquarium driveway.


    Excavation prep work

  • Two surveyors and one tripod will be used.
  • Work will start before high tide at 8:00 a.m., and will last no longer than four hours.
  • No parking or traffic control is required.

Here is a snapshot of the work that has been happening this week:

  • Utility duct bank excavation prep work on Alaskan Way to enable wire and cable installation.
  • Installation of temporary utility poles between Virginia and Pike streets.
  • Continuation of underground utility location, known as “potholing.” This activity requires a truck to create and replace holes in the street to identify utility lines below ground.
  • Hydrant relocation within the fenced-off work zone.
  • Day-time parking restrictions from 6 a.m. – 3:30 p.m., Monday through Friday, on the western side of Alaskan Way between Virginia and Lenora streets to accommodate utility duct bank work.  
  • Steel plates will be used to cover excavated areas after each work day.
