The Alaskan Way Seawall is a seawall which runs for approximately 7,166 feet (2,184 m) along the Elliott Bay waterfront southwest of downtown Seattle from Bay Street to S. Washington Street. [1] The seawall was being rebuilt in the 2010s as part of a waterfront redevelopment megaproject estimated to cost over $1 billion.
The total volume of all these nourishments was 648 million cubic yards (495 m 3) with a total cost of US$3387 million (adjusted to price level 1996). This is US$6.84 per m 3. [17] Between 2000 and 2020 the price per m 3 has gone up considerably in the USA (see table below), while in Europe the price has gone down.
A seawall (or sea wall) is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation, and leisure activities from the action of tides , waves , or tsunamis . [ 1 ]
At Sandwich, Kent the Seabee seawall is buried at the back of the beach under the shingle with crest level at road kerb level. Sea walls typically cost £10,000 per metre (depending on material, height and width), £10,000,000 per km (depending on material, height and width). [citation needed]
The costs of installation, operation and maintenance vary due to: system length (non-linear cost elements) flow rates (sand permeability, power costs) soil conditions (presence of rock or impermeable strata) discharge arrangement /filtered seawater utilization; drainage design, materials selection & installation methods
The primary data set used in cost distance analysis is the cost raster, sometimes called the cost-of-passage surface, [9] the friction image, [8] the cost-rate field, or cost surface. In most implementations, this is a raster grid , in which the value of each cell represents the cost (i.e., expended resources, such as time, money, or energy) of ...
For example, if the replacement cost — not the amount that you paid for it originally, but the amount it would cost to replace it today — for your roof is $20,000, but the roof loses 5 percent ...
