Connecticut Planning Region Index

Connecticut Planning Region Index is a general purpose index map of Connecticut Planning Regions based on mapped information compiled at 1:125,000 scale (1 inch equals approximately 2 miles) and a list of towns in each region available from the State of Connecticut, Office of Policy and Management. The layer is designed to be used to depict Connecticut Planning Regions at small scales or on small maps printed on regular size (8.5 x 11 inch) paper, for example. This Planning Region Index layer does not accurately represent planning region boundaries because it was digitized at 1:125,000 scale. Do not display, map or analyze this index layer with information collected at larger scales. To depict more accurate 1:24,000-scale Connecticut state, county, town, and planning region boundaries on a map, use the layer named Town, which is also published by the State of Connecticut Department of Energy &amp; Environmental Protection. The 2012 Edition reflects consolidation of two organizations into the Lower Connecticut River Council of Governments.

CT Vicinity Town Polygon

Connecticut and Vicinity Town Boundary data are intended for geographic display of state, county and town (municipal) boundaries at statewide and regional levels. Use it to map and label towns on a map. These data are derived from Northeastern United States Political Boundary Master layer.
This information should be displayed and analyzed at scales appropriate for 1:24,000-scale data. The State of Connecticut, Department of Environmental Protection (CTDEP) assembled this regional data layer using data from other states in order to create a single, seamless representation of political boundaries within the vicinity of Connecticut that could be easily incorporated into mapping applications as background information. More accurate and up-to-date information may be available from individual State government Geographic Information System (GIS) offices. Not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.)

Environmental Justice Distressed Municipalities 2021

Environmental Justice Block Groups 2021 was created from Connecticut block group boundary data located in the Census Bureau's 2019 TIGER/Line Shapefiles. The poverty data used to determine which block groups qualified as EJ communities (see CT State statute 22a-20a) was based on the Census Bureau's 2019 ACS 5-year estimate- Table C17002. This poverty data was joined with the block group boundaries in ArcMap. Block groups in which the percent of the population below 200% of the federal poverty level was greater than or equal to 30.0 were selected and the resulting selection was exported as a new shapefile. The block groups were then clipped so that only those block groups outside of distressed municipalities were displayed. Maintenance – This layer will be updated annually and will coincide with the annual distressed municipalities update (around August/September). The latest ACS 5-year estimate data should be used to update this layer.

Environmental Justice Distressed Municipalities 2021 was created from Connecticut town boundary data located in the Census Bureau's 2019 TIGER/Line Shapefiles (County Subdivisions). <div><br /></div><div>From this shapefile, &quot;select by attribute&quot; was used to select the distressed municipalities by town name (note: the list of 2021 distressed municipalities was provided by the CT Department of Economic and Community Development). The selection was then exported a new shapefile. The “Union” tool was used to unite the new shapefile with tribal lands (American Indian Area Geography) boundary data from the 2019 TIGER/Line files. In the resulting layer, the tribal lands were deleted so only the distressed municipalities remained. Maintenance – This layer will be updated annually when the DECD produces its new list of distressed municipalities (around August/September).</div>

Salt Water Limit

Salt Water Limit is a 1:24000-scale, line feature-based layer that depicts the approximate salt water limits of watercourses and embayments in coastal Connecticut. It is important to note that the exact demarcation of the salt-water extent is often not accurate. As stated in the report known as Source 1 in this metadata ("The Boundary Between Freshwater and Saltwater in Connecticut"): "Any definition and demarcation of the boundary between saltwater and freshwater is, of necessity, an approximation. The boundary is transitory and, at times, vague. Within a given body of water, it may vary from day to day, season to season, and year to year, according to such predictable and unpredictable factors as tidal magnitude, rate of evaporation, climatological and meteorological factors, estuarine circulation patterns, and the degree of vertical salinity stratification. An exact delimitation of the upstream limits of saltwater would be a difficult task and one that is probably not necessary for the purposes of coastal management in Connecticut. However, since the primary goal of Connecticut's Coastal Area Management Program is to provide for the balanced, coordinated management of coastal resources, the coastal waters of the state must be clearly and uniformly defined as required in federal and state legislation."
The source data for this layer (a compilation of reports and maps) varied in cartographic scale and age but features were digitized onto standard 1:24,000 scale US Geological Survey (USGS) topographic quadrangle maps. Because of this, the layer does not represent conditions at any particular point in time, nor does every waterbody have an associated salt water extent. This data layer has been updated in 2005 to include more robust attribute information, but no further updates are planned.
Attribute information is comprised of an AV_LEGEND attribute that identifies the feature as the salt water extent ("Salt Limit"), eight "DATASRC[1-8]" attributes that contain a boolean (0,1) value identifying whether or not that particular source was used, a NOTES attribute for additional data source descriptions, a QUADNUMBER attribute and a QUAD_NAME attribute.

Migratory Waterfowl

Migratory Waterfowl is a 1:24,000-scale, polygon feature-based layer that depicts the concentration areas of migratory waterfowl at specific locations within Connecticut. Paul Merola, former DEP Wildlife Biologist, and Greg Chasko, DEP Wildlife Biologist, identified the migratory waterfowl concentration areas based on the Northeast Coastal Areas Study, Joseph Dowhan, 1991 (see Supplemental Information) as well as by using midwinter surveys, breeding surveys and personal observations. The concentration areas are primarily found along the shoreline and the lower tributaries and wetlands of major Connecticut rivers. In addition to depicting the concentration areas, the potential waterfowl species associated with each polygon have been identified and are listed in the attribute table as boolean values indicating their presence or absence. The intent of this datalayer is to assist in the identification of migratory waterfowl resource areas in the event of an oil spill or other condition that might be a threat to waterfowl species. This layer identifies conditions at a particular point in time. It is not updated and it is not a complete representation of all areas of migratory waterfowl in Connecticut.

Channels, Basins, and Anchorages

Channels, Basins, and Anchorages is a 1:20,000-scale, polygon feature-based layer that includes the location of channels, turning basins, and anchorages within (mostly) Connecticut waters. The layer is derived from information depicted on the 2002 edition of digital National Oceanic & Atmospheric Administration (NOAA) nautical charts, Maptech, Inc. and US Army Corps of Engineers (USACOE) Volume 3 - Rivers & Harbors of Rhode Island and Connecticut Project Maps publication dated Sept 1988. The Channels, Basins, and Anchorages layer was compiled during the summer of 2001. The layer represents conditions at a particular point in time. The layer includes representations of areas of channels, turning basins, and anchorages that are or may be periodically maintained by various entitites for commercial and recreational uses. It does not include all possible/potential such areas, just those identified on the source documents; nor does the layer include any buoys or channel markers designating the bounds or entrances to channels, basins, or anchorages. Features are polygon locations that represent the approximate or assumed location of channels, turning basins, and anchorages. Attribute information is comprised of codes to uniquely identify individual features, encode feature information, and cartographically represent (symbolize) channels, turning basins, and anchorages features on a map. Data is compiled at 1:20,000 scale. This data is not updated.

Channels, Basins, and Anchorages is 1:20,000-scale data. It depicts the location of federal and non-federal channels, basins, and anchorages areas. Use this layer to display the locations of underwater boating/shipping areas in and around Long Island Sound and the waterways of Connecticut. Use this layer with 1:20,000-scale map data such as the 2002 digital National Oceanic & Atmospheric Administration (NOAA) Nautical Charts or with any other 1:24,000 scale DEP natural resource data. Not intended for maps printed at map scales greater or more detailed than 1:20,000 scale (1 inch = 1,666.66 feet.)

Subregional Basin Poly

A standardized mapping of natural drainage basins in Connecticut was completed in 1981 by the Connecticut Department of Environmental Protection (DEP). This drainage basin system divided Connecticut into 8 major basins, 45 regional basins, 337 subregional basins, 2,898 local basins, and 7,067 small drainage basin areas. The statewide mapping of natural drainage basins established a hierarchical system of basins based on drainage area size with large major basins subdivided into regional basins, regional basins subdivided into subregional basins, subregional basins subdivided into local basins, and local basins subdivided into smaller and more numerous drainage basin areas. It includes watersheds for Connecticut rivers, streams, brooks, lakes, reservoirs and ponds included on 1:24,000-scale 7.5 minute topographic quadrangle maps published by the U.S. Geological Survey (USGS) between 1969 and 1984. These basin units include smaller watersheds that drain into many of the small streams and ponds in Connecticut. These basin areas are the building blocks for the larger local, subregional, regional and major drainage basins defined by DEP.

Connecticut Subregional Drainage Basins includes 337 drainage basin areas, the majority of which range from 5 to 70 square miles in size and make up, in order of increasing size the larger regional and major drainage basin areas. The subregional basin number (SBAS_NO) uniquely identifies individual subregional drainage basins and is 4 characters in length. There are 335 unique subregional basin numbers. Examples include 6000 for the Housatonic River Main Stem Subregional Basin, 4300 for the Farmington River Subregional Basin, and 6002 for the Schenob Brook Subregional Basin. The first digit (column 1) designates the major basin, the first two digits (columns 1-2) designate the regional basin, and the first 4 digits (columns 1-4) designate the subregional basin. Note, there are slightly more subregional basin areas delineated (374) than unique subregional basin numbers (335) primarily due to a few stream confluences that split the same local basin into two areas. Refer to the Connecticut Subregional Drainage Basin GIS metadata for more information about drainage basin numbers.

Included with the subregional drainage basin boundaries are Subregional Drainage Basins Direction arrows that depict the general direction of surface water flow towards indivicual subregional drainage basin outlets. Theses arrows are meant to indicate where one basin drains into another and are intended aid in visualizing the network of subregional drainage basins in Connecticut. They do not depict the exact location of basin outlets.

These basin boundaries are the digital equivalent of the major, regional and subregional drainage basin boundaries published on the 1:125,000-scale state map entitled Natural Drainage Basins in Connecticut, McElroy, 1981.

Shellfish

Shellfish polygons were digitized from hand drawn polygons representing hardclam, softclam, and oyster beds produced by the Department of Agriculture from their records in 1990 (approximately). The data is general in its nature and should be used only as a guide.This layer should not be construed to depict the actual, absolute locations of any shellfishing resources. Use this layer with other 1:24,000-scale map data such as the Coastal Boundary, Town Boundaries, Roads and Trails, Airports, Railroads and other base map data derived from the USGS 7.5 minute topographic quadrangle maps and compiled at a 1:24000 scale.
