Fisher Associates was enlisted by the New York State Office of General Services and the New York State Department of Environmental Conservation (NYSDEC) to establish approximately 23 miles of boundary lines associated with the Flood Control Project in Olean New York. This boundary was a combination of both Fee and Easement Title interests that New York State has acquired and constructed both levees and floodwalls along the north shore of the Allegheny River, Olean Creek, Kings Brook, Johnson Brook and Two-Mile Creek. Since the construction of these features in the early 1950’s, many changes had occurred along these water courses which could have a negative impact on the structures themselves or the ability to properly inspect and carry out maintenance. Fisher set about establishing the boundaries of approximately 540 parcels originally acquired and documented on approximately 480 maps. The project involved boundary research, field survey, monumentation and mapping. All of the work was completed in accordance with the NYSDEC Land Surveying Standards and Procedures and culminated in the development of over 75 sheets of final mapping.
