This GIS dataset was prepared by the Suffolk County Department of Economic Development and Planning for the Suffolk County Department of Health Services as part of the Suffolk County Subwatersheds Wastewater Plan titled Suffolk County Management Program for the Reduction of Nitrogen Loading from Wastewater Sources. The Department of Economic Development & Planning was asked to provide “parcel-specific buildout land use” for all of Suffolk County. In order to provide parcel-specific buildout land use, the land use for each and every distinct tax map parcel in the Suffolk County Real Property Tax Service Agency Tax Map Album had to be checked and updated. Following this task, parcel-specific land available for residential development was determined, and then residential buildout was calculated.

Land Use MethodologyA significant effort was required to verify and correct the land use codes to produce an accurate parcel-specific land use database, especially given the large geographic extent of Suffolk County, the large number of individual parcels, and the variety of development across the County. In 2017, the Suffolk County Division of Planning & Environment began to comprehensively update its land use inventory for 2016 for all 581,000 land parcels in Suffolk County. The Division’s GIS was employed to link land use data with parcels shown on the Suffolk County Real Property Tax Map.

This feature class was created by exporting the CDP polygon features from the 2020 Census Designated Place State-based shapefile.The Current Place State-based shapefile contains a record for incorporated places, which are established to provide governmental functions for a concentration of people as opposed to a minor civil division (MCD), which generally is created to provide services or administer an area without regard, necessarily, to population. Places always nest within a state, but may extend across county and county subdivision boundaries. An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions. CDPs are delineated for the decennial census as the statistical counterparts of incorporated places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name, but are not legally incorporated under the laws of the state in which they are located
