Adirondack Park boundary line data produced by the New York State Adirondack Park Agency. This version derived from 2015 county tax parcel maps. Source map scale range is approximately 1:1200 to 1:4800. Boundary line is not derived from licensed land survey. The legal description of the Adirondack Park boundary is found in New York State Environmental Conservation Law Section 9-0101. Line attributes in this feature layer include the basis for the line segment such as original patent survey, municipal boundary, or water feature. The text description from the ECL state law beginning at the southern end of the park, proceeding in a counterclockwise direction, is also included with each line segment. The Adirondack Park was created by the State of New York in 1892. The park boundary is commonly referred to as the Blue Line. Reviewed as of March 2018.

The Freshwater Wetlands Act changed in 2022 such that wetlands greater than 12.4 acres in size are regulated regardless of their mapping status. In addition to larger wetlands, the Freshwater Wetlands Act regulates smaller wetlands of “unusual importance” if they meet one of eleven criteria described in the law and regulation. While maps contained provide information on the potential locations of wetlands, the only definitive way to determine if a particular parcel or property contains regulated wetlands outside the Adirondack Park is to request a jurisdictional determination through DEC’s website (https://dec.ny.gov/nature/waterbodies/wetlands/freshwater-wetlands-program). The Freshwater Wetlands Act regulates most development activities located in the wetland or within a regulated “adjacent area.” This adjacent area is a minimum of 100 feet but may be extended for a limited number of particularly sensitive wetlands. Not all activities in and near wetlands are regulated. There are many exempt activities that landowners may undertake without permits. However, if you are not sure of which activities require permits near New York State regulated wetlands, please contact your regional DEC office.Wetlands are classified from Class I (which provide the most benefits) to Class IV (which provide fewer benefits). The classification is based on the work that wetlands do, such as storing flood water and providing wildlife habitat. The system for classifying wetlands is contained in regulation (6 NYCRR Part 664) and the classification of individual wetlands is determined as part of the jurisdictional determination process.View Dataset on the GatewayFor additional information on NYS Freshwater Wetlands, see DEC's website (https://dec.ny.gov/nature/waterbodies/wetlands/freshwater-wetlands-program).For information on wetlands inside the Adirondack Park, please contact the Adirondack Park Agency.For information on wetlands regulated under federal law, please contact the United State Army Corps of Engineers.

This dataset contains data regarding landfills, clipped to the Mohawk River Watershed. It is intended to provide a faithful representation of official New York State regulatory freshwater wetlands maps for GIS resource analysis at scales equal to the 1 to 24,000 scale of original mapping or smaller scales (e.g., 1 to 100,000 scale). The wetlands database is part of a larger database designed to help evaluate watershed/wetland relationships and provide data for cumulative impact assessments. The outreach efforts to share the Agency's natural resource database will encourage resource appreciation and wise use, particularly in a regional context. This data was collected by Stone Environmental, Inc. for the New York State Department of State with funds provided under Title 11 of the Environmental Protection Fund. These data are a set of ARC/INFO coverages composed of polygonal and linear features. Coverages are based on official New York State Freshwater Wetlands Maps as described in Article 24-0301 of the Environmental Conservation Law. Coverages are not, however, a legal substitute for the official maps. Coverages are available on a county basis for all areas of New York State outside the Adirondack Park.APA Wetlands: A set of 18 USGS 7.5' quadrangle-based wetland coverages was prepared for the Oswegatchie-Black, Upper Hudson, and St. Regis River watersheds, primarily within the New York State Adirondack Park (Table 1) using PC Arc/Info 3.4D+ at the Remote Sensing Laboratory, Plattsburgh State University (RSL). Wetlands were delineated on 1:40000 color infrared NAPP transparencies (for the Oswegatchie-Black watershed 1:58,000-scale NHAP color infrared photos were used), transferred to orthophoto overlays using an Image Interpretations Systems Stereo Zoom Transfer Scope, and either hand digitized or scanned into PC Arc/Info format. A digital file extracted from the watershed data layer defined the outer boundary of the mapped area. This wetlands database consists of both polygon and linear features labeled using National Wetlands Inventory conventions. The 138 individual quadrangle files were exported to the New York State, Executive Department, Adirondack Park Agency (NYS APA) running Arc/Info version 8.0. The final MAPJOINED study area polygon coverage comprised of the 18 quad coverages was called STREGWTLND.Mohawk River Watershed Processing: Data was collected from NYDEC or Adirondack Park Agency. All wetland data for Mohawk River Watershed counties were merged and projected to UTM 18N, NAD83. Wetlands were buffered 100 feet using the buffer tool.View Dataset on the Gateway

The original data was collected by B. McMartin, who compiled a map of lands acquired by the State in the Adirondack Park. This information was based upon various sources, including a 1920 series of publications by the NYSDEC. Field checking by McMartin and others was also performed. The original map was a 1:250,000+ scale Great Lot map, color coded with five category types. All boundaries are approximate. Reviewed as of August 2024.

General soil distribution of the Adirondack Park, New York State.The base map soils were plotted on was developed at 1:62500 by the State of New York Office of Planning Coordination. This soils map is referred to as the "Meso Soils Map". 131 different map units or soil associations identify soils for the Adirondack Park. The resolution or minimum mapping threshold of these units is 40 to 100 acres (16-40 ha). It is noted that there are some differences associated with matches across county boundaries.
