Connecticut Department of Transportation Climate Change and Extreme Weather Vulnerability Pilot Project Final Report

This report presents the results of a Climate Resilience Pilot Project conducted by Connecticut Department of Transportation (CTDOT) and sponsored in part by the Federal Highway Administration (FHWA). CTDOT was awarded a pilot to conduct a systems-level vulnerability assessment of bridge and culvert structures six feet to 20 feet in length from inland flooding associated with extreme rainfall events. The project focused on structures in the northwest corner of the state. The Department chose to conduct a vulnerability assessment of inland flooding because in recent years extreme precipitation events have been more frequent and intense, resulting in damage to the Department’s infrastructure in several locations in the State. While this damage has not been significantly widespread, it poses safety concerns and can be costly to repair or replace. The Scope of Work for this project included the following main elements: data collection and field review, hydrologic and hydraulic evaluation, criticality assessment and hydraulic design criteria evaluation. Identification of structures six feet to 20 feet in length in the northwest corner of the state and data collection was accomplished using the state’s bridge inventory. This inventory included over 176 structures on the state system. This inventory was pared down to 60 structures identified for field evaluation. Of the 60 identified for field evaluation, 52 were selected for hydrologic and hydraulic evaluations.
