Alaskan Way Seawall

[1] The seawall was being rebuilt in the 2010s as part of a waterfront redevelopment megaproject estimated to cost over $1 billion.

[citation needed] Despite efforts to prevent marine pest damage when the seawall was designed, after the 2001 Nisqually earthquake, the Seattle Department of Transportation found that gribbles had consumed all the wooden supports in some places.

The seawall rebuild project was estimated to cost $350 million as part of an overall waterfront redevelopment budgeted in 2012 at $1.07 billion.

[2][5] The project is funded by a bond measure that was approved by Seattle voters in the November 2012 general election.

[6] Construction began in 2013 and was completed in 2017, more than a year late and costing $410 million.
