As mayor, Suozzi focused on environmental cleanup of commercial and industrial sites in Glen Cove. A focal point of his administration was redeveloping brownfield and superfund sites. In 1994, the Glen Cove incinerator was permanently closed and dismantled. Under Suozzi's tenure, Glen Cove was also given a credit rating of A-3. At the time, this was the city's highest rating since the 1970s. Suozzi also helped to revitalize downtown Glen Cove by building a new city hall, courthouse, police station, EMS building, new sidewalks, new street lamps, and construction of a multilevel parking garage.
