Topics pertain to the minimum standards of the NFIP only, as well as NYS Building Code requirements NYS building code incorporates most, but not all, of those standards Other related federal/state programs will not be covered Subject matter applies to the special flood hazard area, i.e., The 100-year floodplain 1.0 % flood probability per year Please ask questions We will go over: NFIP History and Basics Obtaining and using Flood Maps and Studies Key Elevation Determination Development Requirements Elevation Certificates Letters of Map Change And More!

3 The National Flood Insurance Act of 1968 The National Flood Insurance Act created the Federal Insurance Administration and directed it to: Identify flood-prone areas within the U.S. Establish flood-risk zones within those areas. Require new and substantially improved buildings be constructed in ways that minimize flood damage. Transfer cost of private property flood losses from taxpayer to property owner. 13 The Three-Legged Stool The NFIP balances three related program areas: Flood Hazard Identification (mapping). Floodplain Management (regulations such as building codes and zoning). Flood Insurance (availability of insurance for property owners in participating communities). F l o o d I n s u r a n ce Flood Disaster Protection Act of 1973 Significant expansion of the NFIP and required: Acceleration of flood insurance studies Notification of flood-prone communities Mandatory purchase requirement Participation in the NFIP for Federal Assistance National Flood Insurance Reform Act of 1994 Expanded flood insurance purchase requirements / Lender penalties for non-compliance Requires lenders to determine if structure is located in a flood hazard area Flood disaster assistance requires maintenance of flood insurance policy Increased Cost of Compliance -- allows insurance payment to elevate, demolish or relocate structure Biggert-Waters Flood Insurance Reform Act of 2012 Phasing Out of Subsidized Flood Insurance Rates Makes it even more crucial to build to proper elevations! Mapping Changes including Future Conditions Mapping Levee Evaluation Procedures 17 Homeowners Flood Insurance Affordability Act of 2014 Eliminates some of the 2012 Changes Property Sales; New Policies; Grandfathering Establishes floor and ceiling of rate hikes: 5% to 18% Annual Rate Increases for Pre-FIRM Properties Until Actuarial Rates are Reached Annual Surcharge: $25 Primary Residential Properties $250 Other Properties Structures Mapped Into SFHA Get PRP, then up to 18% annual increases until X zone rate is reached FEMA must Strive to Limit Rates to No More than 1% of Coverage Many Categories, Particularly Coastal V Zones, Already Significantly Above That More Elevation Certificates Required! 18 3

4 19 20 NFIP Goals Reduce loss of life and property caused by flooding Reduce rising disaster relief costs caused by flooding Make Federally backed flood insurance coverage available to property owners Accomplishing NFIP Goals Require new construction and substantial improvements to be flood resistant Guide future development away from flood hazard areas Transfer flood loss costs from taxpayers to floodplain property owners Prohibit new development in designated floodways that would increase flood heights Roles Federal State Local Private Federal Role Risk identification/mapping Establish development/building standards Provide for flood insurance coverage State Role Establish development/building standards State building code Model local law for flood damage prevention Provide technical assistance to local communities/agencies Under contract with FEMA, evaluate and document community/agency floodplain management activities 23 Local Role Adopt local floodplain management laws Issue or deny development/building permits Inspect development Maintain records 24 4

(DEC Model Local Law; NYS Residential Building Code, R ) For subdivisions or other developments over 50 lots or 5 acres, applicant must provide flood elevation data and build accordingly.

Various source data were used in the interpolation, including topographic maps, beach profiles, aerial photos, and engineering judgment. Controlling features affecting the elevations were identified and considered in relation to their positions at a particular transect and their variation between transects Transect Descriptions Transect Data 14

15 85 86 Flood Insurance Study A flood insurance study (FIS) is a compilation and presentation of hydrologic and hydraulic determinations made for specific watercourses within a municipality. The FIS delineates flood hazard areas and establishes flood elevations thereby serving as the basis for regulating floodplain development and providing flood insurance FLOOD INSURANCE STUDY FIS NARRATIVE Appraises a community's flood problems Estimates flood flow frequency Establishes flood elevation profiles Plots floodplain boundaries Provides data to delineate floodways in some communities Establishes insurance risk zones Background, authority, scope Principal flood problems Existing or proposed flood control projects Engineering methods used Floodplain management/insurance applications Floodway Data Table Some FIS Examples Cross Section Locations Width, Area and Velocity Water Surface Elevation 15

Elevation Certificates The Elevation Certificate Administrative tool of the NFIP Policy rating Support of map revisions and amendments Certify building elevations Community compliance New E.C. just released, Expires 1/30/18, Not yet on Web. Download at: Elevation Certificate Contents Provides detailed, thorough instructions. Requests latitude and longitude. Includes a comprehensive FIRM information section. Provides building elevation information: Detailed building diagrams Multiple building elevations Lowest floor (former reference level) no longer required of the certifier (architect, engineer, surveyor) Measure Bottom Floor and Next Higher Floor Bottom Floor, Next Higher Floor, Lowest Adjacent Grade and Flood Vent Information are used to determine Lowest Floor

20 Elevation Certificate Questions Why is it important to establish BFEs? How does the Elevation Certificate assist the agent to rate a property? Who is qualified to certify elevations for most zones in the Special Flood Hazard Area? How does a surveyor or agent identify an SFHA? Do all buildings in the SFHA need an Elevation Certificate? Does the NFIP mandate using an Elevation Certificate to meet program requirements? Insurance Rating Pre-FIRM and Post-FIRM On or Before 12/31/74 or Before the Initial FIRM Date Pre After 12/31/74 and on or After the Initial FIRM Date Post How do you Find Pre-FIRM Date? FEMA Community Status Book Required for flood insurance rating of post FIRM and some pre FIRM buildings. Determine compliance with floodplain management ordinance. Support map revisions and amendments. Prerequisite for the Community Rating System. 119 When is an Elevation Certificate Required for Insurance Rating? Zones B, C & X: Not in Special Flood Hazard Area (SFHA) No elevation certificate needed Post-FIRM Construction in SFHA Zones Elevation certificate is required Pre-FIRM Construction in SFHA Zones Needed for optional elevation rating Beginning in 2013: Elevation certificate are needed for some pre-firm policies Will eventually be needed for All pre-firm policies in SFHA Current Version: FEMA Form (7/12) Mandatory for use after August 1, 2013 July 31, 2015 expiration date Federal Forms Often Live Past Expiration Date Download from New E.C. at html Fillable PDF and Word Versions New E.C. has been approved; Not on regular FEMA site yet.

Applicant, Local Community, State What is the difference between a LOMR and a LOMR-F? LOMR is a physical change to part of a flood map. Incudes a revised mapped area. LOMR-F does not result in a new map but does exclude a defined parcel or portion of it from the Special Flood Hazard area Hourly Review Fees can Increase the Cost for LOMR s and CLOMR s Structure Site Situation 1: What LOMC Applies?
