To overcome local opposition to the development of a shopping mall in Maryland, proponents of the mall made concessions on the design and management of the facility and executed a legally binding agreement that involved the developers' commitment on several physical and operational features, including a landscaped buffer zone and citizen review of site plans. In Delaware, an agreement for building an office complex made between the city and neighborhood residents included such features as controls on zoning and noise emission during construction, improvement in neighborhood services, and controls on the building and parking. In Colorado, a development committee -- composed of elected officials, three developers, a citizens' coalition, and representatives of the business community -- is considering the future development of some railroad property. While all settings have their unique aspects, successful negotiation requires willing parties, sensitivity to diverse viewpoints, clear communication, technical skills, a written protocol, means for compliance monitoring, and the financial resources necessary to sustain negotiations.
