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.

Cold Water Sites Set

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. 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.
Broadband Data by Block - 2024

The Connecticut Broadband Availability and Adoption Maps were created to help citizens and policymakers understand the strengths and weaknesses of broadband infrastructure in the state. Data is aggregated to the block, tract, and town (county subdivision) levels and includes counts of locations classified as unserved, underserved, and served as well as whether they meet the state goal of 1000Mbps/100Mbps. This feature layer includes all data available at the block level - no adoption data is available at this level.
