Publication Date: March 2025 2023-2024 Parcel Data. Updated annually, or as needed. The data can be downloaded here: https://gis.ny.gov/parcels#data-download. This feature service has two layers: 1) NYS Tax Parcels Public, and 2) NYS Tax Parcels Public Footprint which contains polygons representing counties for which tax parcel polygons are available in the NYS Tax Parcels Public layer. County footprint polygons display when zoomed out beyond 1:37,050-scale. Tax parcel polygons display when zoomed in below 1:37,051-scale. The NYS Tax Parcels Public layer contains 2023-2024 parcel data only for NY State counties which gave NYS ITS Geospatial Services permission to share this data with the public. Work to obtain parcel data from additional counties, as well as permission to share the data, is ongoing. To date, 36 counties have provided Geospatial Services permission to share their parcel data with the public. Parcel data for counties which do not allow Geospatial Services to redistribute their data must be obtained directly from those counties. Geospatial Services' goal is to eventually include parcel data for all counties in New York State. Parcel geometry was incorporated as received from County Real Property Departments. No attempt was made to edge-match parcels along adjacent counties. County attribute values were populated using 2023-2024 Assessment Roll tabular data the NYS ITS Geospatial Services obtained from the NYS Department of Tax and Finance’s Office of Real Property Tax Services (ORPTS). Tabular assessment data was joined to the county provided parcel geometry using the SWIS & SBL or SWIS & PRINT KEY unique identifier for each parcel. Detailed information about assessment attributes can be found in the ORPTS Assessor’s Manuals available here: https://www.tax.ny.gov/research/property/assess/manuals/assersmanual.htm. New York City data comes from NYC MapPluto which can be found here: https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page. Thanks to the following counties that specifically authorized Geospatial Services to share their GIS tax parcel data with the public: Albany, Cayuga, Chautauqua, Cortland, Erie, Genesee, Greene, Hamilton, Lewis, Livingston, Montgomery, NYC- Bronx, NYC- Kings (Brooklyn), NYC- New York (Manhattan), NYC- Queens, NYC- Richmond (Staten Island), Oneida, Onondaga, Ontario, Orange, Oswego, Otsego, Putnam, Rensselaer, Rockland, Schuyler, St Lawrence, Steuben, Suffolk, Sullivan, Tioga, Tompkins, Ulster, Warren, Wayne, and Westchester.

This layer identifies corporate boundaries for all 43 municipal jurisdictions in Westchester County. Coverage originally obtained from New York State Office for Real Property Services (ORPS), and has been substantially modified to better align with current municipal tax parcel boundaries (WCparcels) based on a compilation of 2012 municipal tax parcel datasets. As all of Westchester's town's and cities compile their tax parcel databases independent of one another, there are situations were the tax parcels do not line up at the municipal borders, often resulting in gaps or overlaps of tax parcels at the border areas. This update sought to re-align boundaries to best follow the municipal boundaries as defined by the tax parcels, and often involved making the best possible spatial compromise where there were gaps or overlaps in tax map jurisdictions. It also reflects the 2011 municipal boundary change that resluted from the annexation of a tax parcel from the Town of Mount Pleasant to the Town of New Castle.

The Floodplain Mapping/Redelineation study deliverables depict and quantify the flood risks for the study area. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). Michael Baker Jr. Alexandria office received 2 paper site-plans for the Dansville/Sparta NY Industrial Park from BME Associates, Doug B. Eldred, P.E. as a better source of contours compared to the original topographic study used in the current effective maps. The site-plans were scanned into a TIF, geo-referenced and fit to the Sparta base-map data. A Michael Baker engineer used the contours on the site-plans to adjust the floodplain boundary to match the contours in the Industrial Park. An individual shape file was created just for the Industrial Park area.

The U.S. Geological Survey (USGS) is providing a compilation of geologic well records (n=221) collected from 2014-2020 within the Binghamton East 1:24,000 quadrangle in south-central Broome County, New York. The well records were obtained from: 1) previous U.S. Geological Survey groundwater investigations, 2) the U.S. Geological Survey’s National Water Information System (NWIS), 3) the New York State Department of Environmental Conservation (NYSDEC) Water Well Contractor Program, and 4) the New York State Department of Transportation (NYSDOT). The dataset is in comma-separated values (CSV) format. A companion report, USGS Scientific Investigations Report 2021-5026 (Van Hoesen and others, 2021; https://doi.org/10.3133/sir20215026) further describes data collection and map preparation.

The U.S. Geological Survey (USGS) is providing a polygon feature class containing the delineated areas of postglacial and glacial deposits within the Binghamton East quadrangle of south-central Broome County, New York, 2014-2021. Surficial units included are alluvium, alluvial fans, outwash, glacial lake clay, ice-contact deposit, and variable thicknesses of till. The shapefile was created and intended for use with geographic information system (GIS) software.

Map created in January 2021 that shows all of the 5-digit postal ZIP codes that are contained within or otherwise intersect with the City of Rochester, NY's borders.

The point map shows violations found during the last inspection of the food service establishments. The initial view of the map is broken up into large geographic areas and displays the number of violations in each area. To drill down to a smaller geographic area, click directly on the area of the map or click the plus sign to zoom in on the map. The map can be filtered by facility, city, and county by changing these options under the Filter tab. Last inspection data is the most recently submitted and available data.

This map excludes inspections conducted in New York City (https://nycopendata.socrata.com/), Suffolk County (http://apps.suffolkcountyny.gov/health/Restaurant/intro.html) and Erie County (http://www.healthspace.com/erieny). Inspections are a “snapshot” in time and are not always reflective of the day-to-day operations and overall condition of an establishment. This map is currently updated monthly. Occasionally, remediation may not appear until the following month due to the timing of the updates. Some counties provide this information on their own websites and information found there may be more frequently updated.

This map is made using content created and owned by the federal Department of Housing and Urban Development (Esri user HUD.Official.Content). The map uses their Low to Moderate Income Population by Tract layer, filtered for only census tracts in Monroe County, NY where at least 51% of households earn less than 80 percent of the Area Median Income (AMI). The map is centered on Rochester, NY, with the City of Rochester, NY border added for context. Users can zoom out to see the Revitalization Areas for the broader county region.The Community Development Block Grant (CDBG) program requires that each CDBG funded activity must either principally benefit low- and moderate-income persons, aid in the prevention or elimination of slums or blight, or meet a community development need having a particular urgency because existing conditions pose a serious and immediate threat to the health or welfare of the community and other financial resources are not available to meet that need. With respect to activities that principally benefit low- and moderate-income persons, at least 51 percent of the activity's beneficiaries must be low and moderate income. For CDBG, a person is considered to be of low income only if he or she is a member of a household whose income would qualify as "very low income" under the Section 8 Housing Assistance Payments program. Generally, these Section 8 limits are based on 50% of area median. Similarly, CDBG moderate income relies on Section 8 "lower income" limits, which are generally tied to 80% of area median. These data are derived from the 2011-2015 American Community Survey (ACS) and based on Census 2010 geography.Please refer to the Feature Layer for date of last update.Data Dictionary: DD_Low to Moderate Income Populations by Tract

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The TIGER/Line shapefiles include both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is 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. The boundaries for CDPs often are defined in partnership with state, local, and/or tribal officials and usually coincide with visible features or the boundary of an adjacent incorporated place or another legal entity. CDP boundaries often change from one decennial census to the next with changes in the settlement pattern and development; a CDP with the same name as in an earlier census does not necessarily have the same boundary. The only population/housing size requirement for CDPs is that they must contain some housing and population. The boundaries of most incorporated places in this shapefile are as of January 1, 2020, as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The boundaries of all CDPs were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2020 Census.

The DOH Radon Program contracts with a radon testing laboratory to provide short-term charcoal radon test kits, radon test kit analysis and results to residents. The contract laboratory provides the radon test results to the individual home owner and the DOH Radon Program. All testing data is entered into our database. From this database, we are able to create radon prevalence maps, design special outreach activities and campaigns, and track the location in the home where the detector was placed.

The radon test results obtained from this database may not be reflective of all radon tests completed in New York State. There are approximately 30,000-40,000 radon tests completed each year in New York State that are not purchased through the NYSDOH Radon Program. These tests are completed by resident home owners, inspectors, schools, etc. across the state. A map by town is currently not available, but users can view a map by county. The county map is Radon Test Results By County: Beginning 1987 and can be accessed from the main catalog.
