The Section-Block-Lot (SBL) number refers to the tax maps maintained by the Ulster County Real Property Tax Service Agency. These maps depict the location and approximate size of each parcel of property listed on the assessment rolls of the town of Gardiner. The map sheet number is the Section, which is further divided into Blocks and individual Lots (i.e. SBL 93.68-1-29 = Section 93.68, Block 1, Lot 29 is a 0.50 acre parcel located on Murphy Lane). The SBL tax map number is being increasingly used as a general reference identifier for taxes, building permits, zoning permits, etc.
