Local Capital Improvement Program (LoCIP) Grant Annual Reporting

Pursuant to C.G.S. § 7-536, the Local Capital Improvement Program (LoCIP) distributes direct grants to municipalities for the fiscal year ending June 30, 2024, and forward.  LoCIP distributes formula-based funds to municipalities for eligible local capital improvement projects such as road, bridge or public building construction activities pursuant to C.G.S. § 7-535 through 7-538.

Annually, municipalities report LoCIP grant expenditures for the fiscal year period, as well as any funds not expended.
Bathymetric Contours in Meters for Long Island Sound

The Long Island Sound Study developed these digital data from 1:100,000-scale National Oceanic &amp; Atmospheric Administration (NOAA) and United States Geological Survey (USGS) maps as a general reference to the depth of water in Long Island Sound. In 1996, these data were digitized from paper maps by the Long Island Sound Study (<a href='http://www.longislandsoundstudy.net' rel='nofollow ugc' target='_blank'>http://www.longislandsoundstudy.net</a>) and incorporated into a Long Island Sound GIS database. Not intended for maps printed at map scales greater or more detailed than 1:100,000 scale (1 inch = 1,578 feet.)
Dataset credit: Applied Geographics, Inc. of Boston, Massachussets was contracted by the Long Island Sound Study to automate and digitize these bathymetry data for Long Island Sound. Linda Bischoff, GIS Analyst, digitized the data and created the orginal metadata.

Municipal Fiscal Indicators: Pension Funding Information for Defined Benefit Pension Plans, 2020-2023

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.

Pension Funding Information For Defined Benefit Pension Plans of 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 2020 and beyond 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 September 2025.

The most recent data on the Municipal Fiscal Indicators is included in the following datasets:

Transfer Of Guardianship by SFY, DCF Office, Age at Exit and Length of Stay

This dataset contains aggregate data concerning the number of children that exited DCF care to a Transfer of Guardianship.  These figures are broken out by the DCF Region and Office responsible for the child's care, by their Age Group, and by whether their exit from care occurred within 24 months of their entry to care or not.  It would be appropriate to roll up the data from all variables across multiple time periods, as they represent specific events in the lives of these children.  Please note that these figures do not represent unique children, and so should not be used as the basis for creating a rate based on the child population of the state.  These data form the basis of measurement for the Juan F. Consent Decree Exit Plan Outcome #9: Transfer of Guardianship Within 24 Months, although those figures are reported to the DCF Court Monitor on a quarterly rather than annual schedule.

Additional notes:
The data on 7/15 reflects a decrease in the number of inmates testing positive for COVID-19 and those who have recovered; this decrease was due to an internal data audit that led to the removal of some duplicate information. 

The data on 6/2/2020 reflects an increase in the number of inmates who had been medically cleared; this increase was the result of 146 asymptomatic positive inmates who had completed a 14-day isolation period.
Reunifications by SFY, DCF Office, Gender and Length of Stay

This dataset contains aggregate data concerning the number of children that exited DCF care to be Reunified with a parent/guardian from whom they had been removed.  These figures are broken out by the DCF Region and Office responsible for the child's care, by their Gender, and by whether they had been Reunified within 12 months of their entry to care or not.  It would be appropriate to roll up the data from all variables across multiple time periods, as they represent specific events in the lives of these children.  Please note that these figures do not represent unique children, and so should not be used as the basis for creating a rate based on the child population of the state.  These data form the basis of measurement for the Juan F. Consent Decree Exit Plan Outcome #7: Reunification Within 12 Months, although those figures are reported to the DCF Court Monitor on a quarterly rather than annual schedule.
Shoreline Change Transects 1880-2006

Shorelines are continuously moving in response to winds, waves, tides, sediment supply, changes in relative sea level, and human activities. Shoreline changes are generally not constant through time and frequently switch from negative (erosion) to positive (accretion) and vice versa. Cyclic and non-cyclic processes change the position of the shoreline over a variety of timescales, from the daily and seasonal effects of winds and waves, to changes in sea level over a century to thousands of years. The shoreline "rate of change" statistic thus reflects a cumulative summary of the processes that altered the shoreline for the time period analyzed.

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.
Conservators & Guardians, 1699-1900

A conservator was a person appointed by a court to manage another’s finances or real estate.

A guardian was a person appointed by the court to take care of minor children and their estate.

This index covers the years 1699-1900 and references 1,494 Conservator or Guardian files from the Superior & County Courts for Fairfield, Hartford, Litchfield, Middlesex, New Haven, New London, Tolland, and Windham counties.  Please keep in mind that this index is not comprehensive and additional information may be found within the un-separated files and records of each court.  This index includes the surname and given name of the individual, the town of residence and year of court action, along with court and source location of the original court file.  Some remarks may also be included in the index entries as well regarding the case.

People may request a copy of a file by contacting the staff of the History & Genealogy Unit by telephone (860) 757-6580 or <a href="https://portal.ct.gov/csl/email-us?language=en_US">email</a>.

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
CT Hurricane Surge Inundation

<div><a href='https://www.cteco.uconn.edu/guides/Hurricane_Surge_Inundation.htm' rel='nofollow ugc' target='_blank'>See full Data Guide here. </a><br /></div>Worst case Hurricane Surge Inundation areas for category 1 through 4 hurricanes striking the coast of Connecticut. Hurricane surge values were developed by the National Hurricane Center using the SLOSH (Sea Lake and Overland Surge from Hurricanes) Model. This Surge Inundation layer was created by the U.S. Army Corps of Engineers, New England District. Using ArcInfo's Grid extension, LiDAR bare earth elevation data from both the State of Connecticut and FEMA was subtracted from the worst-case hurricane surge values to determine which areas could be expected to be inundated.
