Traditions of America – a Radnor, PA-based developer of active adult communities, mostly restricted to those 55 and older – is has been given a green light by Cranberry’s Board of Supervisors to build a Planned Residential Development on a 55.1-acre site along Rochester Road at the Beaver-Butler county line. Each of the 103 living units in the two-phase project will be a detached structure, purchased and customized by the resident. The surrounding property – 44 percent of which will remain as open space – will belong to and be cared for by the plan’s homeowners’ association. A separate home on a seven-acre tract is to be built for the Blackstone family, which has lived on the site for generations. Plans call for a community center, a pool, a fitness center, parklets, a trail system, and street lights, as well as streetscape enhancements along Rochester Road. The plan’s interior street network will remain privately owned.
