Norwich Connecticut sits at the confluence of the Shetucket, Yantic, and Thames rivers in New London County — one of the most flood-prone urban locations in eastern Connecticut. The city is near Naval Submarine Base New London and hosts significant manufacturing operations. The Thames River watershed creates flooding risk during major rain events. New London County's submarine infrastructure creates military community considerations for Norwich.
