Warminster is considering transforming a 16-acre industrial site into a 200-home mixed-use development within walking distance to the nearby SEPTA regional rail station. The plan calls for 14 housing units per acre and would include a walking path to the train station and small retail space on the site. The transit-oriented development (TOD) district in Warminster follows in the footsteps of Ambler, Hatboro and Upper Gwynedd in Montgomery County. The purpose of a TOD is to capitalize on the proximity to a transit facility and to promote ridership and economic and community development, according to a 2007 Delaware Valley Regional Planning Commission report.
