With the completion of the largest in-river flood protection project in the six-year history of the King County Flood Control District, hundreds of homes and businesses near the Green River in Auburn now have enhanced flood protection for this flood season - and for decades to come.
With the completion of the largest in-river flood protection project in the six-year history of the King County Flood Control District, hundreds of homes and businesses near the Green River in Auburn now have enhanced protection for this flood season – and for decades to come.
Crews have wrapped up the major work of building a new levee that stretches for nearly one mile along the western bank of the Green River through several Auburn neighborhoods.
Tearing out the leaky old, constrictive Reddington Levee and building the new levee farther back from the river makes room for flood flows to fan out and lose their erosive force, while creating areas for improved fish and wildlife habitat.
The setback levee project was managed by the Water and Land Resources Division of the King County Department of Natural Resources and Parks, and funded by the Flood Control District at a cost of more than $17 million. Scarsella Bros., Inc. was the general contractor.
“The Reddington Levee is a prime example of the Flood Control District’s mission to invest in safety improvements for people, property and communities along our rivers,” said Flood Control District Chair Reagan Dunn. “This new levee not only provides greater protection for the thousands of residents and workers who live and work in Auburn but also helps to protect vital transportation infrastructure from Green River flooding.”
“This project improves flood protection for hundreds of families and businesses,” said Flood District Supervisor Pete von Reichbauer. “In order to improve our job market and provide stability, it is vital that we continue to address our aging infrastructure needs. The completion of the Reddington Levee Setback project is an important step forward in protecting the safety of our residents.”
The Reddington Levee directly protects more than 300 residential properties and 275 commercial properties with a combined value of $680 million, plus several major transportation corridors from Green River flooding.
Building the new 4,800-foot-long setback levee required excavating an estimated 160,000 cubic yards of soil – the equivalent of 80,000 full-sized pickup truck loads.
With all that soil out of the way, crews constructed the new setback levee, installed nearly 4,300 feet of drainage pipe, and placed 48,000 tons of rock armoring along the levee.
On the wide expanse of open ground between the new setback levee and the river channel, crews placed 340 logs and planted native vegetation – consisting of more than 18,000 trees and shrubs – to help hold the soil in place and provide habitat for fish and wildlife.
The Reddington Levee setback project is part of a larger overall flood management strategy for the Green River. The Flood District will substantially complete four additional Green River projects this year: Hawley Road Levee, Boeing Levee, Black River Pump Station fuel system improvements and the Russell Upper North Reach Levee.
