NYCT Feasibility Study and Flood Mitigation/Resiliency


HAKS, as a team member, provided architectural and surveying services to New York City Transit (NYCT) for a feasibility study and design of flood mitigation/resiliency at 12 critical Lower Manhattan, Queens and Brooklyn locations.  The objective of the project was to prevent flood water from entering fan plants in NYCT system facilities by closing/modifying right-of-way openings. Flood prevention included near- and long-term mitigation/resiliency for Category 2 hurricane storm surges.  Alternatives included currently used industrial concepts applied to NYCT facilities or modification of vendor or NYCT equipment.

Near-term solutions included the closing and hardening of entrances, fan plant vents, emergency exit hatches, conduits, ventilators, and other openings adjacent to the fan plants.  Long-term measures included final design for flood mitigation/resiliency and assisting NYCT in seeking approvals from numerous agencies, utilities and NYCT stakeholders for the specified locations.

Mitigation measures at some locations included redesigning the entire building envelope to withstand required flood levels.  The final design was based on an analysis of the various concepts outlining pros, cons, operational requirements, cost-benefit, the architectural impact on the community, etc.
