(RECAP: Equinox Investments LLC is bidding to rezone itself. The Loudoun developer, based at 43571 John Mosby Highway, is in talks with the county to rezone its headquarters property for 77 townhomes, 128 multi-family units and business uses, likely retail or commercial. The 21.5-acre parcel, a combination of vacant land and the 20,000-square-foot Equinox headquarters building that fronts Route 50, is located just west of East Gate, a 330-acre mixed-use project that Equinox helped develop with Baltimore-based Atapco Properties.)
