The areas studied by detailed methods were selected with priority given to all known flood hazard areas and areas of projected development and proposed construction.
All or portions of numerous flooding sources in the county were studied by approximate methods. Approximate analyses were used to study those areas having a low development potential or minimal flood hazards. The scope and methods of study were proposed to, and agreed upon by, FEMA, the local communities, and Greene County.
Between cross sections, the boundaries were interpolated using topographic maps at a scale of 1:4,800 with a contour interval of 4 feet (Geomaps Inc., 1985); using aerial photographs at a scale of 1:9,600 (Geomaps, Inc., 1985); and using topographic maps at a scale of 1:24,000 with a contour interval of 20 feet (U.S. Department of the Interior, 1943, 1945, 1946, 1960, 1965).

For the July 19, 2001, FIS report, more detailed topographic information was provided by the Town of Windham for FEMA.
The authority and acknowledgments for the Towns of Durham, Greenville, Halcott, and New Baltimore, are not available because no FIS reports were published for these communities.
For this countywide FIS, the New York State Department of Environmental Conservation (NYS DEC) and FEMA entered into a Cooperative Technical Partners (CTP) Agreement to collaboratively produce this countywide FIS. The revised hydrologic analyses were prepared by PAR Government Systems Corporation (PGSC). The revised hydraulic analyses were performed by both PGSC and the NYS DEC. PGSC performed this work under contract with the NYS DEC. This work was completed in June 2004.
Minor adjustments were made to the flood elevation boundaries along community boundaries in order to produce a seamless FIRM for the entire county.
Base map information shown on the FIRM was provided in digital format by the New York State Office of Cyber Security and Critical Infrastructure Coordination. This information was derived from 30-centimeter resolution natural color orthoimagery from photography dated April 2004 and 30-centimeter resolution color infrared orthoimagery from photography dated April 2001.
The projection used in the preparation of this FIRM was Universal Transverse Mercator (UTM) Zone 18. The horizontal datum was NAD 83, GRS80 spheroid. Differences in datum, spheroid, projection or UTM zones used in the production of FIRMs for adjacent jurisdictions may result in slight positional differences in map features across jurisdiction boundaries. These differences do not affect the accuracy of this FIRM. This FIS covers the geographic area of Greene County, New York.
All or portions of the following flooding sources were studied by detailed methods. Limits of detailed study are indicated on the Flood Profiles and on the FIRM.
Acra Tributary, Batavia Kill, Catskill Creek, Climax Tributary, Cob Creek, Coxsackie Creek, East Branch, Murderers Creek, East Kill, Gooseberry Creek, Hudson River, Kaaterskill Creek, Mitchell Hollow Creek, Potic Creek, Reservoir Tributary, Sawmill Creek, Schoharie Creek, Shingle Kill, Sleepy Hollow Lake, Stony Clove Creek, Trout Brook, West Branch Murderers Creek, West Kill.
As part of this countywide FIS, updated analyses were included for the following flooding sources. The format shows the stream name, and a description of the limits of revised or new detailed study:
Batavia Kill: From its confluence with Schoharie Creek to approximately 0.44 mile upstream of Big Hollow Road.
East Kill: From its confluence with Schoharie Creek to Colgate Lake.
