Cleaning up contaminated sites is keeping Landau Associates busy. But despite what Director of Client Services Steve Johnson says is shaping up to be a real busy summer season, the slackening of the local economy is beginning to be felt.

“We’re starting to feel a little bit of the softness,” says Johnson. “We haven’t had a slow period yet, but we haven’t been at full capacity either.”

Johnson says that site remediation comprises about 70 percent of the firm’s business. Major ongoing projects include environmental support work for the remediation of Ross Island in Portland, a sediment remediation of the Superfund site at Todd Shipyards on Harbor Island and the Cascade Pole site — where utility poles were treated with chemicals to prevent rot — at the Port of Olympia.

Other facets of Landau’s business include geotechnical work for transportation projects and significant natural resources and environmental permitting activities. The firm also has contracts for on-call environmental services with a number of governments, including the city of Federal Way and Pierce County, as well as a number of school districts.

With 70 employees, Landau has grown slightly this year. Johnson envisions “adding a few more key people” before the year is out.

In addition to Edmonds, Landau has offices in Portland, Tacoma and Spokane.
