A member of a longtime Spokane business family is suing the state Department of Transportation over the way it has handled the acquisition of real estate for a planned north-south freeway. David Moore, owner of Zig's Electric & Plumbing Supply Co., claims that the state has essentially condemned his commercial property at 4312 N. Market Ave., by purchasing the adjacent Ziggy's Building Materials at 4220 N. Market Ave., and leaving him with property he cannot lease or sell.
