Note on Dates

Dates listed are based on research that covered calendar years and various fiscal years. To the best of our ability, we have tried to use the calendar year. However, some sources did not always indicate if calendar year or fiscal year was being discussed. Also, during the process of defining the original logical geographic planning regions, not all boundaries were initially released. "[T]he commission identified tentative planning regions. However, it did not make the boundaries public until it was contacted by local groups in a geographic area that were interested in establishing a regional planning authority. At that point, CDC staff set up meetings with municipal officials to discuss the proposed boundaries. After reviewing the feedback, advice, and information from those in the region, the Connecticut Development Commission determined the final definition of the region and announced it publicly. After that, the towns within the defined area were responsible for the steps required to form a Regional Planning Authority."[14]

"The boundaries of the Midstate Planning Region, originally designated as the Northern Middlesex County Region, are determined by the Planning and Budgeting Division of the Department of Finance and Control, State of Connecticut, as specified by Connecticut's regional planning enabling legislation. Factors which are considered in this determination include economic and social interrelationships, common physiographic features, similar community goals, a degree of balance and self-sufficiency, common areas of concern, etc."

"The original definition of the Midstate Planning Region included the seven towns of Cromwell, Durham, East Hampton, Haddam, Middlefield, Middletown and Portland. After intensive study and reevaluation of the factors which influenced the region's boundaries, the Connecticut Development Commission, at its meeting of June 21, 1967, redefined the region to include the Town of East Haddam."
