It was decided to make appraisals using a before and after technique. The after value would reflect the value of the property after the development rights had been acquired. This was the basic bundle of rights theory: only the right to development was being bought; hence, the after value was theoretically a pure farm. A farm expert, who specialized in appraising farms in New York State and the immediate adjacent states, was hired. It was determined that there were no pure farms on Long Island. The farm expert concluded that the farming of the land in Suffolk County was a holding operation as all of the farmlands had the potential for development for other than farmlands and this potential was reflected in the prices paid for farm land on Long Island. This was no recent occurrence as it had always been thus on Long Island. The farmers were forced out by development from Kings County to Queens County, to Nassau County, and finally to Suffolk County.
