![]() ![]() The new maps were developed in partnership with the National Weather Service and the U.S. ![]() The mover from three to six zones added 600,000 New Yorkers to the zone boundaries. People can find out if they live within one of the six evacuation zones by going to or calling 311. One of the key changes in the flood zones is that they now number 1 through 6 instead of A, B, and C.Ĭhanging the flood zones will increase the city’s flexibility for tailor-made evacuations according to storm conditions.ĭeputy Mayor Cas Holloway said in a statement the updated flood zones “incorporate the best-available data” to give the city new tools to more effectively communicate to the people most at risk, depending on the characteristics of a particular storm. Additionally, if a structure sustains flood-related damage on two separate occasions within a 10-year period, and the cost of repairs for each flood event equals or exceeds 25% of the fair market value, then the structure is considered substantially damaged.NEW YORK-The long-awaited updated flood zone evacuation maps have been released by the City of New York. In the case of damage, if the cost of repairs equal or exceed 50% of the value of the structure before it was damaged, then the structure must be brought into compliance with the Floodplain Regulations. be designed to minimize flood damage, be constructed of flood resistant materials, and not have any new enclosed area lower than that of the existing structure. If the repairs or the improvements to the structure equal or exceed 50% of the fair market value of the structure before the damage/improvement, then the improvement or repair must comply with the Floodplain Regulations (i.e. However, there are limitations on this allowance. Structures within a floodplain can be repaired or improved. What about structures that are damaged within a floodplain or structures that the owner wants to improve that are within a floodplain? Substantial Improvement/Substantial Damage The intent is to better protect existing structures and new properties from flooding based on the current FIRMs and floods anticipated in the future. These regulations are designed to require minimum standards when building a new structure in the floodplain or when remodeling or repairing an existing structure. View the FIRMs to determine your property's flood risk, talk to your insurance provider to determine if you need additional coverage and visit NFIP's website for more information.Īs an NFIP-participating community, Manhattan is required to follow, adopt and apply a minimum set of development regulations for properties and structures in the high-risk floodplains (Zones A, AE and AH on the FIRMs). The City of Manhattan participates in the National Flood Insurance Program, which entitles homeowners, renters and business owners to purchase flood insurance to protect their property and/or belongings in the event of a flood.įlood insurance for a structure and its contents is available to all residents, regardless if you are in an identified flood-prone area. Property identified in the high-risk areas of the Digital Flood Insurance Risk Maps (DFIRMs) will be required to carry flood insurance, with rates based on the flood risks that went into effect on March 16, 2015. The more open space within this sensitive environment, the less potentially damaging floods could become.Ī typical home insurance policy does not cover losses from a flood. These designated open areas help keep the floodplain in natural balance. This open space ranges from parks to former residential lots that have been converted to open space to school recreational areas such as soccer fields and baseball diamonds. The City of Manhattan maintains approximately 743 acres of designated open space in the Special Flood Hazard Area (SFHA). Any kind of development in a floodplain displaces potential floodwaters, which then creates a larger problem downstream or even just next door. In addition to damaging a threatened ecosystem, the more development in a floodplain, the worse flooding becomes. This is why it is crucial that we limit development in floodplains as much as possible. In addition to this, floodplains provide habitat for countless species of animals such as deer and foxes as well as fish and birds. Floodplains act as overflow basins for rivers and streams, so that when a large amount of rain falls at once, the rivers and streams have somewhere to distribute excess water. Floodplains are important ecological features which perform natural functions that are designed to keep floodwaters in check. ![]()
