55 Water Street – Flood Mitigation

This commercial property, located on Manhattan's southeast waterfront, sustained extensive damage as a result of flooding during Hurricane Sandy. Langan was retained to provide site/civil engineering services in support of flood mitigation efforts, which included the design of a perimeter flood wall system. Our services included flood elevation consulting; Builders Pavement Plan for sidewalk improvements and grading adjustments; NYCDOT Revocable Consent support for placement of the flood wall bearing plates and foundation within the street and adjoining right of ways; and development of an interim flood mitigation strategy. During construction we provided oversight of flood wall foundation construction and assisted the owner in applying for a FEMA Letter of Map Amendment.
