MU, Mixed-Use. The Mixed-Use District is established to provide for single-family based residential uses, residential uses of compatible scale, and retail and office designed to serve local and regional market demands. The district therefore primarily aims to maintain a neighborhood scale of development in portions of Route 30 currently bearing a traditional mixed-use scale of development and to provide a market-based, yet compatible, transition of residences fronting key north-south collectors of North Versailles.
