MTA Bridges and Tunnels
Flood Mitigation Study at RFK, Bronx Whitestone and Throgs Neck Bridges
SEPC, as a subconsultant, evaluated service buildings, toll plazas, and other structures for Throgs Neck, Bronx Whitestone and RFK Bridges for exposure to potential flooding. The project also included Robert Moses Building at Randall’s Island housing maintenance shops and administration building.
The investigations included inventory of all sensitive infrastructure equipment and their locations, determining existing elevations for all facilities at all floors. All items were recorded into GIS data and a matrix developed to determine the exposure to compare with potential 50 year and 100 year expected flood levels.
The study recommended safeguards against future potential flooding which included relocation of sensitive material and equipment to higher elevations and offered various alternates to prevent the flooding of the buildings.
