The Ulster County Parcel Viewer, an online GIS map with various optional layers including tax map.

GIS is an abbreviation for Geographic Information System. The Town Planning Board and Zoning Board of Appeals often identify applications by the tax map section-block-lot (SBL) number. You can use this identifier in the Ulster County GIS to find the geographic location of the subdivision, special permit or zoning variance application. Use the link above to "Ulster County GIS", select the municipality (Gardiner), then from the menu "Tools" select "Search by Parcel ID". Enter the SBL number in the notice and then generate a map.
