1997 Municipal and Private Open Space

Municipal and Private Open Space Property contains parcels owned by municipalities, land trusts and other private entities throughout the state.  Generally, these parcels are open space and include schools, cemeteries, recreation, conservation and preservation land.  This layer can be used with the Federal Property and DEP Property layers for a more comprehensive understanding of open space and recreation land throughout the State of Connecticut.

This layer has not been updated since 1997 and may not be accurate.  For more accurate and current open space parcel data, please see the Protected Open Space and the Protected Open Space Phase 1 feature classes.  However, please note that the definition of Protected Open Space is not the same.  As a result, cemeteries, developed recreation facilities, and schools are not included in the more current Protected Open Space layers.
Municipal Fiscal Indicators, 2014

Municipal Fiscal Indicators is an annual compendium of information compiled by the Office of Policy and Management, Intergovernmental Policy Division (IGP), Municipal Finance Services Unit (MFS). The data contained in Indicators provides key financial and demographic information on municipalities in Connecticut. Municipal Fiscal Indicators contains the most current financial data available for each of Connecticut's 169 municipalities. The majority of this data was compiled from the audited financial statements that are filed annually with the State of Connecticut, Office of Policy and Management, IGP Division. This database of information includes selected demographic and economic data relating to, or having an impact upon, a municipality’s financial condition.
Aquifer Protection Areas Set

See full Data Guide here. Aquifer Protection Areas Set is a 1:24,000-scale, polygon feature-based layer that includes all Preliminary (Level B) and Final (Level A) Aquifer Protection Areas approved by the Connecticut Department of Energy and Environmental Protection (DEEP). These areas represent the land area contributing ground water to active public water supply wells or well fields that serve more than 1000 people that are set in sand and gravel aquifers (stratified drift deposits). These areas are commonly referred to as wellhead protection areas. The Aquifer Protection Areas were delineated by the individual water utilities owning the well fields and submitted to the DEEP for approval. The preliminary mapping provides a general estimate of the area contributing ground water to the well field. The final mapping is based on extensive, site-specific, detailed modeling of the ground water flow system. As the final mapping is completed it replaces the preliminary mapping. The layer is based on information collected and compiled from 1991 to the present. The layer depicts current conditions. Attribute information is comprised of codes to uniquely identify individual features, encode the aquifer protection area type and status, and cartographically represent area features on a map. Data is compiled at 1:24,000 scale. This data is updated as final mapping becomes available.
Infrastructure Investment and Jobs Act (IIJA)/Bipartisan Infrastructure Law (BIL) Project Data

The Bipartisan Infrastructure Law (BIL) is the largest long-term investment in our infrastructure in nearly a century. Signed into law by President Joe Biden on Nov. 15, 2021, this historic act will make life better for millions of Connecticut residents and create economic growth. To date, Connecticut has received $6.4 billion in Bipartisan Infrastructure Law (BIL) funding with over 167 specific projects identified for funding. Many more projects will be added in the coming months, as funding opportunities become grant awards and as formula funds become specific projects. By reaching communities across Connecticut – including rural communities and historically underserved populations – the law makes critical investments that will improve the lives of Connecticut residents and position the state for success.
CT Municipalities

The CT Municipalities layer consists of individual polygons representing each of the 169 municipalities that make up the state of Connecticut. This feature class is based on the Towns layer originally created by CTDEEP from USGS maps. The towns from the CTDEEP data were dissolved to create 169 records (one for each town). Fields were added and deleted to create a generic schema.The CT Municipalities feature class was created in (municipality) alphabetical order. Fields were added to identify the municipality number and the CTDOT Municipality number, which differ from each other in some cases. In 1947 the town of Saybrook officially changed its name to Deep River. Other State agencies and municipalities changed their numbering systems to reflect this name change, however, most of what is now CTDOT kept their existing numbering system. This is why the CTDOT town number for Deep River is 122, the number formerly assigned to Saybrook.The square miles associated with each town are for their interior land mass area. Coastal communities have boundaries that extend into Long Island Sound. These town boundary extensions into Long Island Sound are not included in the square miles field.CTDOT has created and will maintain a cartographic rendering of the geometric shape of Municipal boundaries. Official Town and City designations as incorporated areas consisting of an authorized governing body are managed by CT's Office of Policy and Management (OPM).CTDOT has undertaken a good faith effort to represent the boundaries cartographically in a fair and equitable fashion, from the best available data compiled from existing state, regional, and local resources including - existing historical cartographic renderings of the boundary locations, supplemental survey information, and map submissions.  Corrections can be submitted to the CTDOT for incorporation and correction where applicable.Attribution was assigned to designations managed by a variety of entities that strictly follow Municipal boundaries and additional designations will be added as requested by State, regional, and local partners.

SBE/MBE Spending Allocation Goals Viewer

This page contains the State of Connecticut’s annual Small Business Enterprise (SBE) and Minority Business Enterprise (MBE) spending allocation goals by three-digit NAICS industry category and State of Connecticut purchasing/account codes for goods and services for each fiscal year. The goals support Connecticut’s spending allocation program under Public Act 25-168, Section 200, which replaces the prior fixed agency set-aside structure with annual, industry-based SBE and MBE spending allocation goals.

The goals are intended to encourage agencies and organizations to include certified small and minority-owned firms in bidding and purchasing opportunities. These are aspirational statewide goals intended to support planning for good-faith efforts. They are not purchase-by-purchase quotas and do not replace existing procurement statutes, regulations, policies, purchasing authority, competition requirements, or award standards.

For each mapped purchasing/account code, the dataset identifies the applicable three-digit NAICS code, the NAICS industry category description, and the SBE and MBE spending allocation goals. Agencies should use this dataset before making a purchase to identify the NAICS category and spending allocation goals associated with the purchasing/account code expected to be used.

This data story is published by the Department of Administrative Services to promote transparency and support consistent implementation of Connecticut’s SBE/MBE spending allocation program across state agencies. This page will be updated annually.

Eelgrass Beds Historic Polygon

Eelgrass Beds Historic Set:



Historic Eelgrass Points is a 1:24,000-scale, point feature-based layer that depicts the locations of historic eelgrass beds (Zostera marina) in Long Island Sound, the Connecticut River, the Quinnipiac River and other bays, harbors and waterbodies in Connecticut's coastal area. It also includes several points located along the north shore of Long Island. There are a total of 131 point features, the majority of which are located east of the Connecticut River. Point features in this layer are compiled from two major sources: 1) the polygon feature label points in the Historic Eelgrass Beds polygon layer representing sources with a mapping component; and 2) additional points that were based on historic literature review that had no mapping component. Source information including source description and collection date for each point is described in the layer's table data. Feature locations are inexact. Because of the variety of source maps and methods used for their automation, this coverage should be considered to have limited spatial accuracy and is appropriate for general uses only. Actual data collection ranged from 1873 through 1996. This layer was published in 1997 and is not updated. It does not represent current conditions.

Historic Eelgrass Bed Polygons is a 1:24,000-scale, polygon feature-based layer that depicts the locations of historic eelgrass beds (Zostera marina) in Long Island Sound and the Niantic River, as well as in other bays, harbors and waterbodies in Connecticut's coastal area. It also includes several points located along the north shore of Long Island. There are a total of 52 polygon features, all of which (except the Long Island points), are located within or east of the Niantic River. This layer can be used with Historic Eelgrass Points. This layer does not represent current conditions. Rather, it depicts historic eelgrass bed locations that were observed and defined either cartographically or narratively over the course of many years and from various sources. The dates of each source's data collection are noted in the attribute table. Feature locations are inexact. Because of the variety of source maps and methods used for their automation, this information should be considered to have limited spatial accuracy and is appropriate for general uses only. The data was taken from maps of various scales and projections that were drawn between 1905 and 1996. These maps were reduced to approximately 1:24,000 scale and adjusted for best fit; eelgrass areas were redrafted onto USGS Topographic Quadrangle maps for digitizing. In order to create a single polygon coverage, areas were considered to represent a maximum extent of eelgrass beds. This layer was published in 1997 and is not updated.

Critical Habitats

<div><a href='https://cteco.uconn.edu/guides/Critical_Habitat.htm' target='_blank' rel='nofollow ugc noopener noreferrer'>See full Data Guide here.</a><br /></div>Connecticut Critical Habitats is a polygon feature-based layer with a resolution of +/- 10 meters that represents significant natural community types occurring in Connecticut. This layer is a subset of habitat-related vegetation associations, described in Connecticut's Natural Vegetation Classification, that were designated as key habitats for species of Greatest Conservation Need in the Comprehensive Wildlife Conservation Strategy. These habitats are known to host a number of rare species including highly specialized invertebrates with very specific habitat associations. Some key habitats are broken into subtypes based on natural variations in plant species dominance and/or vegetation structure. These differences are apparent in the subtype names. Connecticut Critical Habitats can serve to highlight ecologically significant areas and to target areas of species diversity.

This layer can be used to perform various spatial analyses that pertain to Critical Habitats, to aid in determining site management and conservation priorities, prioritizing field surveys, and to further document the distribution and abundance of State-listed and/or rare vertebrate and invertebrate species within the significant habitats. Use this layer appropriately with data maintaining similar resolution. Not intended for maps printed at a resolution greater or more detailed than 1:2000.
State of CT: Open Expenditures - Ledger – ARCHIVE ---Deprecated

This data allows citizens to view who received payments from the state for goods or services and how much they received. The data can be explored by searching for specific payee names or by browsing by Government Function. The Open Checkbook app( http://opencheckbook.ct.gov) allows the user to drill down from aggregated spending accounts all the way down to each individual payment to a payee. 

The  data is updated nightly and therefore reflects current spending activities more accurately than any other publicly available source. In general the data reflects all payments made up to 24 to 48 hours prior to view.

Certain payee names have been removed in order to protect the privacy of individuals, in accordance with Health Insurance Portability and Accountability Act (HIPAA) regulations or where the information is otherwise protected by law. 

Redacted information includes:
•Payees who are statutorily protected
•Information that would lead to violating HIPAA laws
•Information of Minors

This dataset will be removed from data.ct.gov on 11/3/2021 as part of efforts to declutter and improve the quality of the Open Data Portal.

Cold Water Habitat Sites

<p>Cold water habitat was determined using available fish and
water temperature data collected by the Connecticut Department of Energy and
Environmental Protection (CT DEEP) Monitoring and Assessment, Inland Fisheries
and Volunteer Stream Temperature Programs. The analysis to date includes years
1988 - 2023. The mapping application will be updated with new or updated
information as it is collected, quality assured and analyzed. CT DEEP has a
robust data set of stream fish community and temperature logger data dating
back to the late 1980's. In previous work (Beauchene et al., 2014) these data
were used to develop cold water temperature metrics and fish species that were
indicators of cold-water habitat. With the knowledge gained from the
compilation of recent Connecticut based studies, identification and subsequent
classification of cold-water habitat can be made with data from either fish or
stream water temperature. To catalog cold water habitat CT DEEP analyzed all
available fish and water temperature data collected in accordance to standard
operating procedures to identify cold water rivers and streams. The analysis to
date includes years 1988 – 2023 and identified 1,716 samples and 792 sites
indicating cold water habitat from both fish community and temperature logger
data.<span>  </span>If a site was measured to have
cold water habitat with either fish community or water temperature using the
June-August metric at any time during our surveys, it was considered cold water
stream habitat. Additional information regarding the data and project can be
found on:
https://portal.ct.gov/DEEP/Water/Inland-Water-Monitoring/Cold-Water-Stream-Habitat-Map.</p>
