by Sheila AshFederal and local authorities Tuesday broke ground on the first phase of a new mixed-use project called "the EDGE" at Liberty Green.The EDGE is a mixed-income expansion to the Liberty Green housing development near Liberty and Hancock streets. It will be made up mostly of houses and apartment buildings.Developer Bill Weyland of CITY Properties says there will also be a 28-unit building for students and faculty at the nearby U of L Health Science Center."We’ve worked very closely with the medical school dean and his staff in order to put together a vision that we think will be very appealing to those students that they have and actually help to allow them to recruit more students and really tie that whole program into this very urban place," he says.Construction is expected to begin in the next month. The multi-million dollar project is federally funded.
