The business started by Karen Haug's father helped build St. Paul's skyline.

Advance Shoring and two sister companies, all situated along Jackson Street in an industrial area of St. Paul, provided everything from the scaffolding used in the St. Paul Cathedral renovation to the crane currently onsite for the Regions Hospital expansion.

Now, Haug has come across a construction project she wants no part of: the redevelopment of her property by the St. Paul Port Authority. And she is pledging to reopen a debate that swept the country in the wake of a controversial 2005 U.S. Supreme Court case, Kelo v. City of New London, paving the way for government to take private land for redevelopment.

"Isn't it ironic that we're being asked to leave the very city that we helped create?" Haug said Wednesday.

Advance Shoring, founded in 1960, moved to its current site a decade later. It rents out heavy equipment for local construction efforts, and its projects have included the Science Museum of Minnesota, the Xcel Energy Center and the Minnesota Life building.

But decades ago, its 12-acre property was used as a dump, and contamination there includes lead and methane, which the Port Authority said is at 37 times the minimum explosive levels. The Port hopes to use a loophole in 2006 eminent domain reforms passed by the state Legislature in the wake of Kelo that allows cities to take private property in need of environmental cleanup.
