The Department of City Planning is seeking input on special flood resilience zoning from residents of the City’s floodplain. City Planning released a video explaining their flood resiliency goals. Resiliency is the “ability to withstand, recover, and emerge even stronger after a storm.” The City has adopted a multitude of approaches that, in combination, make the floodplain more resilient. The City is increasing emergency services, building breakwaters and wetlands to reduce the force of waves, building seawalls and bulkheads to block floodwaters from spreading inland, hardening utilities and infrastructure to prevent power outages, and making strides in resilient construction. Resilient construction of buildings is integrated in the City’s Building Code.

The Federal Emergency Management Agency (“FEMA”) defines flood risk, floodplains, and insurance rates. The City Department of Buildings enforces FEMA’s guidelines by adopting them into the City’s Building Code. The Building Code requires residential buildings to have space below the flood elevation line that allows water to enter and exit without causing damage. Commercial buildings must have ground floors impermeable to water entry. Buildings constructed using the more recent resiliency standards survived Hurricane Sandy with minimal damage. However, many buildings in the floodplain were built before the adoption of these Building Code regulations and the 1961 Zoning Resolution.  (read more…)
