There is now a green light for the $76.8 million mixed-use residential project to be built next to the Metro-North train station on Halstead Avenue in downtown Harrison, in Westchester County, and adjacent financial incentives. The Westchester County Industrial Development Agency unanimously approved $1,352,966 in sales tax exemptions for the transit-oriented development in late November. Avalon Bay Communities is bringing 143 rental units, seven affordable units, 27,000 square feet of commercial space, and 758 on-site parking spaces to the new three-building complex. That includes two landscaped plazas bridging the train station platform with Halstead Avenue, and a design that ties the new construction to the existing streetscape.
