Kansas City officials said cleaning up asbestos at a failed development site will cost about half the amount originally estimated.

City officials said Thursday that test pits at the Citadel development site turned up less asbestos contamination than previously predicted. City planner Claude Page said that means the cleanup costs will likely come in at about $1.1 million instead of the $2 million or more that was originally estimated.

The Kansas City Star reported that the city has a $500,000 federal grant for the cleanup, and the cleanup should be finished this summer.

The cleanup is necessary because the developer failed to properly monitor asbestos removal before some homes were torn down in 2006 to make way for the failed shopping center.
