In 1983 City Councilor Bruce C. Bolling introduced and sponsored a new and revolutionary concept to the Boston urban development scene. His parcel-to-parcel linkage plan, accepted by the Boston City Council and Boston Redevelopment Authority, requires developers of downtown commercial real estate to contribute funds for housing improvements in the city's depressed neighborhoods. The linkage concept, researched and fashioned by political strategist Joyce Ferriabough, has resulted in the leveraging of linkage monies for a number of projects to revitalize Boston's neighborhoods.
