The community development corporation Blue Hills Community Services has been working to rebuild the Blue Hills neighborhood for the past 38 years. And they've just begun construction on their latest project: a $3 million energy-efficient renovation of a building at 50th and Prospect. The new center will house the organization's headquarters, and provide office space and training for about a dozen small-time contractors at a time. The contractor incubator will be the first of its kind in the Kansas City area.
