Alternative Groundwater Protection Criteria Area (GWPC)

The Alternative GWPC layer is to be used when evaluating the Alternative GWPC provision, section 22a-133k-3(d)(2) of the RSRs, amended on February 16, 2021. This layer represents the GA groundwater classification area where an Alternative GWPC could be eligible if a groundwater plume is located in the designated Alternative Groundwater Protection Criteria area and all other requirements of 22a-133k-3(d)(2) have been satisfied. The layer provides more flexibility in achieving groundwater compliance in areas with no current or future drinking water use.
Federal Open Space

[See full Data Guide here. ] Federal Open Space is a polygon feature-based layer that includes land owned in either easement or fee simple interest by the federal government. This layer is based on information that was collected and mapped at various scales and at different levels of accuracy. Types of property in this layer include open space and recreational land open to the public. Examples include National Park Service land, Army Corps of Engineers land, etc. This layer has not been updated since 2004 and may not be accurate.
VetRep Data

This feature layer contains contact and location information for Municipal Veterans Representatives across Connecticut, as designated under Connecticut General Statutes §27-135. Each record represents a municipality or regional entity responsible for assisting Veterans at the local level. The data supports the "[Find a Veterans Representative]" tool by providing accurate and up-to-date information on local Veterans service contacts.

DOT Scenic Land Strips

Department of Transportation (DOT) Scenic Land Strips contains parcels, generally long narrow strips of land, that were purchased by the DOT under the Federal Highway Beautification Act of 1965. The purpose of this program was to reduce the proliferation of billboards and other unsightly structures or facilities along federally designated highways. There are 33 parcels of land located along seven highways in eight towns. Highways and the corresponding towns where DOT Scenic Lands are located include: * U. S. Route 44 in Norfolk * Interstate 91 in Meriden * Interstate 84 in Plainville * Interstate 395 (formerly State Route 52) in Killingly * State Route 2 in Glastonbury * State Route 8 in Litchfield * State Route 9 in Essex and Deep River This does not include all land owned by DOT. The source map scale is unknown. No specific scale is recommended. This data should not be used for legal boundary purposes. [See full Data Guide here.]

2023 Connecticut 5' Contours (beta)

Source: 1 foot contours were generated for each production block from the final bare earth DEMs using ArcGIS software. Using ArcGIS software, the contours were validated for correct topology, including must not intersect, must not self intersect, and must not have dangles. Contours are then manually reviewed with the 3D breaklines to ensure complete coverage, correct coding, data integrity and that contours behave correctly around water bodies, water crossings, and elevated features such as overpasses. The contours are then clipped to individual tiles as creating one dataset for the entire project renders the feature class un-usable. Enclosed contours completely within building footprints were removed from the final contour dataset. Coordinate System: The data was developed based on a horizontal datum/projection of NAD83 (2011), State Plane Connecticut, U.S. Survey Feet and vertical datum of NAVD88 (GEOID18) Use Constraints: There are no formal use restrictions. However, users should be aware the conditions may have changed since the data was originally collected, and some areas may no longer accurately reflect current surface features. This data should not be used for critical decision-making without a full understanding of their limitations.
LIS Environmental Observation

The LIS Environmental Observations layer provides the location of monitoring devices at a particular point in time. The devices are orchestrated by three groups.

Long Island Sound Integrated Coastal Observing System (LISICOS) provides environmental information ranging from weather, water quality, waves, and currents. NOAA Center for Operational Oceanographic Products and Services (CO-OPS) provides the national infrastructure, science, and technical expertise to monitor, assess, and distribute tide, current, water level, and other coastal oceanographic products and services. US Army Corps of Engineers New England District (ACOE-NED) is responsible for managing the Corps' civil works and military program responsibilities in a region that includes Connecticut.

CT Full State

This CT Full State layer consists of two individual polygons representing the land and Long Island Sound borders that make up the state of Connecticut. This land portion of this feature layer is directly derived from the [CTDOT Municipalities] feature layer geometry, created by CT Department of Transportation. The full state is created by dissolving all the municipalities into one polygon. The Long Island Sound portion is derived from points defining the Connecticut state waters boundary line, as described in the [CTDEEP Marine Fisheries Information Circular] (Table 6). This feature layer includes US Census Federal Information Processing Standards (FIPS) codes that are associated with the state of Connecticut. ──────────┬────────────────────────────────────────────────────────────────────────────────────────────────────── Field name│Field description ──────────┼────────────────────────────────────────────────────────────────────────────────────────────────────── StateFIPS │US Census FIPS code associated with the state. ──────────┼────────────────────────────────────────────────────────────────────────────────────────────────────── Type │Describing if the polygon includes the “land” portion of the state or the “Long Island Sound” portion. ──────────┼────────────────────────────────────────────────────────────────────────────────────────────────────── ObjectID │Unique Object ID. ──────────┴──────────────────────────────────────────────────────────────────────────────────────────────────────
CT Councils of Governments

This CT Councils of Governments layer consists of individual polygons representing each of the 9 regional Councils of Governments (COGs) that make up the state of Connecticut. This feature layer is directly derived from the [CTDOT Municipalities] feature layer geometry, created by CT Department of Transportation. The municipalities are dissolved into their associated regional Councils of Governments. This feature layer includes US Census Federal Information Processing Standards (FIPS) codes that are associated with each municipality. This was included based on information from [Connecticut County to County Subdivision Crosswalk] from the US Census. Connecticut’s 9 planning regions provide a geographic framework within which municipalities can jointly address common interests and coordinate such interests with state plans and programs. CGS Section [16a-4a] authorizes the Secretary of the Office of Policy and Management (OPM) to designate or redesignate the boundaries of logical planning regions. CGS Section [4-124j] authorizes the member municipalities of each planning region to establish a formal regional governance structure known as a council of governments (COG). These regions have been recognized as county-equivalents and supersede the eight legacy counties in the state.
