Numerous East Haven officials, first responders and residents denounced a recent FAA study at a hearing on Saturday that projected minimal harm from the proposed Tweed New Haven Airport expansion. The environmental assessment was co-signed by New Haven city staff who embraced the economic benefits of the plan. Residents cheered as Carfora called for an environmental impact statement which, under the National Environmental Policy Act, would provide a more detailed study of the expansion’s impact on the nearby environment and residents. Carfora said the estimated 61,300 cubic yards of fill required for the expansion construction would only worsen flooding in the flood-prone airport and surrounding neighborhoods, explained that the increase of 21.62 acres in impervious surface would mean large volumes of polluted stormwater runoff and pointed to impacts from heavy airport traffic on the local town green and beach.
