Subregional Basin Line

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.

Tidal Wetlands 1970s

Tidal Wetlands 1970's represents the historic regulatory tidal wetland boundaries produced during the early 1970's by the State of Connecticut Department of Agriculture and Natural Resources, which defined the areas of tidal wetlands that were subject to the 1969 Tidal Wetlands Act.
The first comprehensive tidal wetlands mapping of the state was undertaken during the 1970's following the passing of the Tidal Wetland Act (TWA) in 1969. The TWA established a permit program to regulate activities conducted in tidal wetlands. The TWA had a mandatory mapping requirement to let property owners know the approximate location of regulated tidal wetland areas. Unfortunately, during the adoption of the regulations, the tidal wetland maps were given greater importance, than was originally intended, such that the maps were used to determine the regulated area rather than the actual site conditions. The mandated revisions to the maps were never undertaken as no additional funding was authorized. (See the Tidal Wetlands 1990's Datalayer for subsequent wetlands mapping.)
The regulatory tidal wetland boundaries were surveyed in the field and these boundaries were transferred to 1&quot; = 200' (1: 24000 scale) mylars derived from black and white low altitude aerial photography. It is known that the mapping criteria did change and evolve as the surveyors became more experienced with tidal wetland delineation. It also was not unusual for controversial parcels to be omitted as a result of adverse comments received at public hearings prior to the adoption of the maps. Additionally, no maps were ever produced to show &quot;formerly connected&quot; wetlands, a special type of wetlands. Thus, even at the time of their adoption, the 1970's tidal wetland maps did not include all known tidal wetlands in Connecticut.
For more information, please refer to the Tidal Wetlands Report at http://www.ct.gov/dep/lib/dep/gis/coastalresources/tidal_wetlands_report.pdf .

Connecticut County Index

Connecticut County Index is a general purpose index map of Connecticut counties based on information compiled at 1:125,000 scale (1 inch equals approximately 2 miles). The layer is designed to be used to depict Connecticut counties at small scales or on small maps printed on regular size (8.5 x 11 inch) paper, for example. This County Index layer does not accurately represent Connecticut county boundaries because it was digitized at 1:125,000 scale. Do not display, map or analyze the County Index layer with information collected at larger scales. To depict more accurate 1:24,000-scale Connecticut state, county, and town boundaries on a map, use the layer named Town, which is also published by the State of Connecticut Department of Energy &amp; Environmental Protection.

Bedrock Geology Set

Bedrock Geology Set is a 1:50,000-scale, polygon and line feature-based layer describing the solid material that underlies the soil or other unconsolidated material of the earth for Connecticut. Bedrock geologic formations are described as polygons in terms of formation name (incorporating geologic age), rock type, and tectonic terrane association. Tectonic forces are responsible for the present day geologic configuration of the continents. Resulting terranes are regionally fault bounded rocks of a similar tectonic history. Each terrane is named after its plate tectonics ancestry. Geologic lines include contacts, faults, and terrane boundaries. Terrane boundaries are named for the faults involved. The geologic contacts and faults are delineated and classified by type. Polygon feature attribute information is comprised of codes to identify individual bedrock geologic units, their formation name, description and size. Line feature attributes identify, name and describe bedrock contacts, faults and terrane boundaries between these bedrock geologic units. Data is compiled at 1:50,000 scale and is not updated. A complete description of the bedrock mapping units with mineralogical descriptions and a brief history of Connecticut geology are included in the Supplemental Information Section for reference.

Northeast County Polygon

Northeastern United States County Boundary data are intended for geographic display of state and county boundaries at statewide and regional levels. Use it to map and label counties 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.)

Erosion Susceptibility Set

Connecticut Erosion Susceptibility a 1:24,000-scale, polygon feature-based layer that was developed as a predictive tool to show areas most susceptible to terrace escarpment type erosion. The layer compiled from the soils and quaternary geology data layers and was field tested during October-December, 2005. The Erosion Susceptilibity layer was developed as part of Project #03-02 Statewide GIS Analysis and Mapping of the Geologic Conditions Contributing to Eroding Terrace Escarpments. The layer does not represent eroding conditions at any one particular point in time, but rather base or general conditions which can be accounted for during planning or management strategies. The layer includes 4 types of areas susceptible to erosion, ranked 1 (most susceptible) through 4, and their descriptive attribute. Areas outside of the mapped polygons can be considered less susceptible to erosion. Data is compiled at 1:24,000 scale. This data is not updated.

Connecticut Erosion Sites is a site specific, point feature-based layer developed at 1:24,000-scale that includes decriptive information regarding the character of the erosion (severity, slope, geologic factors) at selected locations through out the state. The layer is based on information collected and compiled during October-December, 2005 while field testing the applicability of the Erosion Susceptilibity layer developed as part of Project #03-02 Statewide GIS Analysis and Mapping of the Geologic Conditions Contributing to Eroding Terrace Escarpments. The layer represents conditions at a particular point in time. The layer includes 83 locations and descriptive attributes (site name, severity of erosion, description, etc) as well as attributes from a spatial join with merged soils and quaternary geology layers. Features are point locations that represent the selected study areas within the state; it is NOT a comprehensive inventory of erosion locations. Data is compiled at 1:24,000 scale. This data is not updated.

Long Island Sound Submerged Cable And Pipeline Areas

The Long Island Sound Submerged Cable and Pipeline Areas layer is a polygon feature-based layer that includes the location of submerged cable and/or pipeline areas in Long Island Sound. These can include, but are not necessarily limited to: electric transmission lines, telephone and/or fiber optic cables, natural gas and/or petroleum pipelines, etc. The layer is based on information from the 2002 edition of digital National Oceanic & Atmospheric Administration (NOAA) nautical charts provided by Maptech, Inc., a field survey completed by Ocean Surveys Inc (OSI) in 2002, and the *proposed* location of a pipeline from plans provided by Broadwater Energy in 2005. The Long Island Sound Submerged Cable and Pipeline Areas layer was originally created during the summer of 2002. The layer represents conditions at particular points in time. The layer includes representations of areas of underwater cables and/or pipelines. It does not include cable and/or pipeline areas landward of mean high water, nor does it include all possible submerged cables, pipelines, or other similar features. Features are polygon locations that represent the approximate or assumed location of cables and/or pipelines for the purpose of cartographic representation and general planning. Attribute information is comprised of codes to uniquely identify individual features, encode cable/pipeline type of information, and cartographically represent (symbolize) cable/pipeline features on a map. Data is compiled at 1:20,000 and 1:24,000 scale. This data is not planned for regular updates. Last updated 10/4/2005
