With warehouse distribution centers becoming a bigger part of Connecticut’s economy, South Windsor next week may adopt a one-year moratorium against any new ones. Kerrigan in January called on the planning and zoning commission to pass a one-year ban; it began a hearing on the idea last week and will resume it on April 5. Builders have put up a series of warehouses and fulfillment centers over the past decade, and Kerrigan said the result is higher truck traffic and around-the-clock elevation in road noise. In the past 13 years, the town has approved seven major warehouses — Coca Cola, Aldi’s, FedEx, Amazon, Mobis, Vistar and Home Depot — that created 2.2 million square feet of buildings covering more than 280 acres. South Windsor is just one of the Connecticut communities seeing growth in fulfillment centers and warehouses; most of the towns near Bradley International Airport got more in the past 20 years.
