Within the FIRMs, the floodplain is divided into different areas of risk: the V-Zone, A-Zone and Shaded X Zone. These provisions are found in Appendix G: Flood-Resistant Construction of the Building Code, and apply within the City’s floodplain.įIRMs identify buildings in the floodplain and are used for the applicability of Appendix G as well as for calculating flood insurance rates. ![]() Once the City joined the program, NFIP required the adoption and enforcement of flood resilient Building Code regulations. The NFIP program is managed by the Federal Emergency Management Administration (FEMA), and has three components: to provide flood insurance, to improve floodplain management, and to develop maps of flood hazard zones. In 1983, the City of New York joined the National Flood Insurance Program (NFIP) and adopted the Flood Insurance Rate Maps (FIRMs). More information on DCP’s work on climate resiliency. These regulations, which will expire on 2020, can be found in the Appendix A to Article VI, Chapter 4 of the Resolution.Ĭity Planning is currently working with community members and property owners across the city’s floodplain to update the Flood Resilience Zoning rules through a future citywide zoning text amendment. In addition, on July 23, 2015, the City Council adopted the Special Regulations for Neighborhood Recovery, a text amendment intended to accelerate recovery in Sandy-impacted neighborhoods, by simplifying the process for documenting the condition of existing buildings, and by establishing a new zoning envelope on small lots for homes that need to be reconstructed. The Flood Text provisions can be found in Article VI, Chapter 4 (Special Regulations Applying in Flood Hazard Areas) of the Zoning Resolution and will expire within one year of the adoption of new final Flood Insurance Rate Maps, which are the official flood maps on which FEMA has delineated the 1% annual floodplain, the 0.2% annual floodplain, Base Flood Elevations and floodways. 230 was an emergency action that took an important first step to suspend zoning regulations that would have presented obstacles to reconstructing buildings damaged by Hurricane Sandy to more flood-resilient standards. 230 (issued on January 31, 2013), was replaced by the Flood Resilience Zoning Text Amendment, which was adopted by the City Council on October 9, 2013.

The Flood Text encourages flood-resilient building construction throughout designated floodplains by removing regulatory barriers that hinder or prevent the reconstruction of storm-damaged properties. Please refer to the MiEnviro Floodplain Service Request guidance for more information.The Flood Resilience Zoning Text (the “Flood Text”) is one part of a wide range of efforts by the City to recover from Hurricane Sandy, promote rebuilding, and increase the city’s resilience to climate-related events, including coastal flooding and storm surge. There is no charge for this service, however, depending on workload, the determination may take 4 to 8 weeks. To make such an estimate, the District floodplain engineer will need a map (preferably with a property description) showing the location of the property, an estimate as to how high the property is above the water level of the river, lake or stream, and how far the building site is away from the water. įor site specific questions, the Water Resources Division will provide an estimated 100-year flood elevation. For more information on the Flood Hazard Mapping process, see. Check out FEMA's floodplain mapping website. A community status book may be obtained from FEMA identifying the communities which have a floodplain map developed under the National Flood Insurance Program.įEMA is also in the process of developing digital flood insurance rate maps (DFIRM). ![]() ![]() Of the 1776 communities (Cities, villages, and townships) in Michigan, currently about 1,004 communities have floodplain maps that have been developed by FEMA. The primary source of floodplain mapping information in Michigan is the Flood Insurance Rate Maps (FIRMs), which are developed by the Federal Emergency Management Agency (FEMA).
