A handful of small businesses along the path of a future light-rail line in St. Paul says construction on the project has led to damages on their property. A mosque reports that digging outside the building caused a foundation leak and flooded the basement, which still reeks of mold two months later. Outside a Hmong clothing chop, a heavy metal awning looks like it's about to fall off the wall. But Chicago-based general contractor Walsh Construction is denying responsibility for the damages, saying the problems predate construction. The Metropolitan Council, which is managing the project, says these disputes are between the property owners and the contractor, and that there's little the council can do.
