Connecticut/Cities and towns Discussion View history

The state of Connecticut is divided into 169 Cities and Towns. When assigning the "City" property to Road Segments please use the primary names of this list. Village/historic names (indented under their parent town) are not mapped in CT except for rare cases when there is segment name duplication with one notable exception of Mystic. If this is the case, the village may be added as Alt-Names and RPPs created. Please discuss with CT senior leadership before making this type of edit. CT Town Map

Statewide Resources

Statewide Town Parcel Viewer by CT ECO/DEEP:

CT ECO/DEEP - Connecticut Environmental Conditions Online (CT ECO) is the collaborative work of the Connecticut Department of Energy and Environmental Protection (DEEP) and the University of Connecticut Center for Land Use Education and Research (CLEAR) to share environmental and natural resource information with the general public.
In 2018, Public Act 18-175, section 6 was passed and required each municipality to submit a digital parcel file and some assessment information each year to the Council of Governments (COGs) to which it belongs. The Office of Policy and Management (OPM) subsequently asks the COGs to voluntarily share the files so they can be made available for download in one location on the OPM website.
CT ECO is simply sharing the information and has no involvement in the creation or editing of the datasets including tabular information. Parcel Viewer Details and Help

Regional Council of Governments (RCOG) Resources

Connecticut's nine planning regions, established under Sec. 16a-4c, Gen. Stat., provides a geographic framework within which municipalities can jointly address common interests, and coordinate such interests with state plans and programs. The municipalities within each region have voluntarily created a Regional Council of Governments (RCOG), through local ordinance to carry out a variety of regional planning and other activities on their behalf. *Town names below link to Town Website Homepages
