Municipal Fiscal Indicators: Type and Number of Other Post-Employment Benefits (OPEB) Plans, 2021-2023

Municipal Fiscal Indicators is an annual compendium of information compiled by the Office of Policy and Management, Office of Finance, Municipal Finance Services Unit (MFS). Municipal Fiscal Indicators contains the most current financial data available for each of Connecticut's 169 municipalities.

The data contained in Indicators provides key financial and demographic information on municipalities in Connecticut. The data includes selected demographic and economic data relating to, or having an impact upon, a municipality’s financial condition.

Other Post-Employment Benefits (OPEB) for Connecticut Municipalities, compiled by the CT Office of Policy and Management in the annual Municipal Fiscal Indicators report.

Post-employment benefits are typically provided by municipalities to former employees or their beneficiaries as compensation for services rendered while these employees were still active. These benefits are generally divided into two broad categories – pension benefits (retirement income) and Other Post-employment Benefits (postemployment benefits other than pensions, referenced as OPEB). Forms of OPEB typically include healthcare benefits and benefits such as disability and life insurance provided outside of the pension plan.

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, Office of Finance. Unlike prior years' where the audited financial information was compiled by OPM, the FY 2021 information in this edition was based upon the self-reporting by municipalities of their own audited data.

The most recent edition is for the Fiscal Years Ended 2019-2023 published in July 2025.
State Wildlife Action Plan Conservation Opportunity Areas Set

<p>The 2025 Connecticut State Wildlife Action Plan conservation opportunity areas (COAs) represent locations partners can conduct actions to benefit wildlife populations and habitats and achieve State Wildlife Action Plan Goals. There are 7 total COAs that represent broad actions: protect, connect, restore, manage, partner, inform, and research and monitor. This effort combined ecological and social data in a spatial prioritization software called Zonation to identify priority areas that reflect the 7 actions. Each COA has different ecological and/or social data included to reflect its unique goal.&nbsp;</p>
COVID-19 Cases and Deaths in Nursing Homes by Week - ARCHIVE

As of 6/1/2023, this data set is no longer being updated.

Connecticut nursing homes are required by the Centers for Medicare and Medicaid Services (CMS) to report on the impact of COVID-19 on their residents and staff through CDC’s National Healthcare Safety Network (NHSN). This reporting is intended to reflect recent COVID-19 activity in nursing homes.

Data presented here from NHSN reflect resident and staff COVID-19 cases and COVID-related deaths reported for Connecticut nursing homes for the previous week, Thursday–Wednesday. All nursing homes follow NHSN definitions and instructions when reporting to the NHSN COVID-19 module, ensuring data are reported in a systematic way. These data do not show where the resident or staff got infected.

Detailed information about COVID-19 reporting for nursing homes and NHSN can be found here: https://www.cdc.gov/nhsn/ltc/covid19/index.html

Residential Solar Investment Program (RSIP) Enrollment

Through the Residential Solar Investment Program (RSIP), the Connecticut Green Bank, in partnership with a network of contractors and inspectors, helped more than 46,300 households access solar energy since 2012, surpassing the statutory target of 350 MW (reaching 378 MW) one year ahead of the December 2022 deadline.

Highlights
- $1.43B total investment
- $156M total incentive
- $0.41/W average incentive
- $3.79/W installed cost

How it works
- RSIP provided rebates and incentives to make rooftop solar more affordable for homeowners.
- When panels produce electricity, they save money and create Solar Home Renewable Energy Credits (SHRECs).
- Utilities entered into Master Purchase Agreements (MPAs) with the Green bank to buy SHRECs to comply with policy programs.
- Green bonds are created via SHREC revenue and purchased by both individual and institutional buyers.
- Revenue from MPAs and Green Bonds support RSIP incentives and cover administrative costs.

This dataset is an anonymized comprehensive listing of all approved and completed projects supported by the RSIP. It contains information on system costs, sizes, participating contractors, and other details gathered during the RSIP.

Eelgrass Beds Historic Set

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.

Glacial Sediment Line

Thickness of Glacial Sediment in Connecticut and Long Island Sound Set:
The Thickness of Glacial Sediments in Connecticut and the Long Island Sound Basin layer contains interpretive polygon data representing the thickness of glacial sediments in Connecticut and the Long Island Sound Basin. Compiled as part of the Quaternary Geologic Map of Connecticut and Long Island Sound Basin, Stone and others (1998, 2005). Includes thickness of glacial sediments in 50 foot (0-50, 50-100) and then 100 foot (100-200, 200-300, etc) intervals.
Data derived from original mapping at 1:80,000 scale for the Long Island Sound basin and at 1:125,000 scale on the land in Connecticut. The data are NOT recommended for use at higher resolution scales. The purpose is to show the thickness of glacial sediments on land in Connecticut and in the Long Island Sound Basin. This layer can be used other geologic information shown on the Quaternary Geologic Map of Connecticut and Long Island Sound Basin (USGS publication SIM-2784) as well as other geologic GIS data layers for Long Island Sound derived from the U.S. Geological Survey (USGS) / Connecticut Department of Environmental Protection (DEP) Marine Geology Cooperative Program. Complimentary data layers include the marine transgressive surface (marinet) and thickness of postglacial deposits (pgthkpol) found on Georeferenced Sea-floor Mapping and Bottom Photography in Long Island Sound (USGS Openfile report 00-304).
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.)
COVID-19 Vaccinations by Census Tract - ARCHIVE

As of 1/13/2022, this dataset is no longer being updated and has been replaced with a new dataset, which can be accessed here: https://data.ct.gov/Health-and-Human-Services/COVID-19-Vaccinations-by-Census-Tract/ekim-wqrr

COVID-19 Vaccinations by Census Tract and Age Groups, including Ages 16+, Ages 16-44, Ages 45-64, and Ages 65+.

CT Vaccination Program (COVP) data obtained from CTWiZ. COVP Coverage data suppressed if the any of the following conditions were met:
-Coefficient of Variation of Denominator is > 30%	
-Numerator is <5
-Population is estimated to be 0 (zero)

Population data obtained from the 2019 Census ACS (www.census.gov)

DPH recommends that these data are primarily used to identify areas that require additional attention rather than to establish and track the exact level of vaccine coverage.   

All analyses are provisional and subject to change. 

Census tract coverage estimates can play an important role in planning and evaluating vaccination strategies. However, inaccuracies in the data that are inherent to population surveillance may be magnified when analyses are performed on population subgroups within census tracts. We make every effort to provide accurate data, but inaccuracies may result from things like incomplete or inaccurate addresses, duplicate records, and sampling error in the American Community Survey that is used to estimate census tract population size and composition.  These things may result in overestimates or underestimates of vaccine coverage.  

Some census tracts are suppressed. This is done if the number of people vaccinated is less than 5 or if the census population estimate is considered to be unreliable (coefficient of variance > 30%). Coverage estimates over 100% are shown as 100%. We suggest that the data are used primarily to identify areas that require additional attention rather than to establish and track the exact level of vaccine coverage. All analyses are provisional and subject to change.

Caution should be used when interpreting coverage estimates for towns with large college/university populations since coverage may be underestimated. In the census, college/university students who live on or just off campus would be counted in the college/university town. However, if a student was vaccinated while studying remotely in his/her hometown, the student may be counted as a vaccine recipient in that town.
Spill Incidents from July 1, 2022 to Recent for Download

This data set represents information reported after June 30, 2022 to the Department of Energy and Environmental Protection (CT DEEP), generally to the CT DEEP Dispatch Center, regarding releases of substances to the environment, generally through accidental spills.
The update frequeny on this data set is about once a month.

For current information related to releases reported to CT DEEP from July 1, 2022 to the present, go to Incident Reports for Releases Reported to CT DEEP July 1, 2022 to present at: https://connecticut.hazconnect.com/listincidentpublic.aspx.
For a dataset related to releases reported to CT DEEP from July 1, 1996 to June 30, 2022 refer to the CT Open Data dataset:  https://data.ct.gov/Environment-and-Natural-Resources/Spill-Incidents-from-January-1-1996-to-June-30-202/wr2a-rnsg

This dataset is a snapshot of data from the live system that is updated periodically to provide to public users the download capabilities offered from the CT Open Data platform.
Connecticut General Statutes Section 22a-450 requires anyone who causes any discharge, spillage, uncontrolled loss, seepage or filtration of oil or petroleum or chemical liquids or solid, liquid or gaseous products, or hazardous wastes which poses a potential threat to human health or the environment to report that release to the CT DEEP. Reports of releases from other persons are also included in this dataset.

Examples of what may be included in a spill incident record includes: Administrative information (unique spill case number), Spill date/time, Location.,Spill source and cause, Material(s) and material type spilled. 

Data limitations and factors to consider when using this data:
This data is limited to information about a spill incident as it was known at the time it was reported to CT DEEP. Although some data reflects updated information after the time of the initial notification, CT DEEP idoes not field check and verify all reported information. Therefore, information later determined to be incomplete or inaccurate may exist in this data set. There may also be spelling errors or other unintentionally inaccurate data that was transcribed in the spill incident report.

This dataset is a subset of records and information that may be available about releases that have occurred at specific locations. This dataset does not replace a full review of files publicly available either on-line and/or at CT DEEP’s Records Center.

For a complete review of agency records for this or other agency programs, you can perform your own search in our DEEP public file room (https://portal.ct.gov/DEEP/About/Environmental-Quality-Records-Records-Center-File-Room) located at 79 Elm Street, Hartford CT or at our DEEP Online Search Portal at: https://filings.deep.ct.gov/DEEPDocumentSearchPortal/Home
