USEFUL TERMINOLOGY
  • Base Flood A flood having a 1 chance of being
    equaled or exceeded in any given year also known
    as the 100-year flood. (Over a 30-year period
    there is a 26 chance of flooding.)
  • Base Flood Elevation The height above sea level
    to which flood water would be expected to rise in
    a base, or 100-year flood event.
  • Development Any man-made change to improved or
    unimproved real estate, including but not limited
    to buildings or other structures, mining,
    dredging, filling, grading, paving, excavation,
    drilling, driving of piles, land clearing, and
    permanent storage of materials and/or equipment.
  • Lowest Floor The lowest floor of the lowest
    enclosed area of the building (including
    basement).

A Zone measured from the top of the floor.
V Zone measured from the bottom of the floor.
7
USEFUL TERMINOLOGY
  • Regulatory Floodway The channel of a river and
    the adjacent land areas that must be reserved in
    order to discharge the base flood without
    increasing the water surface elevation.
  • Special Flood Hazard Area An area having flood
    or flood-related erosion hazards. Shown on the
    maps as A or V Zones.
  • Substantial Damage/Improvement
    Applies when the cost to
    repair a damaged structure or to improve or
    reconstruct an existing structure in the flood
    hazard area would equal or exceed 50 of the
    market value of the structure.

8
The NFIP was created by Congress in 1968 to
  • reduce loss of life and property caused by
    flooding
  • reduce rising disaster costs caused by flooding
    and
  • make federally-backed flood insurance available
    to all property owners in participating
    communities.

FLOODPLAIN MANAGEMENT ORDINANCES
The Ordinance is the principal tool for achieving
the goals of the program, by
New Hampshire Model Floodplain Management
Ordinance For Communities with Special Flood
Hazard Areas Meets the Minimum Requirements of
Section 60.3(c) of the National Flood Insurance
Program Regulations This ordinance, adopted
pursuant to the authority of RSA 67416, shall be
known as the Town (City) of
________________________ Floodplain Management
Ordinance. If the town has a zoning ordinance
insert the following The regulations in this
ordinance shall overlay and supplement the
regulations in the Town (City) of
Zoning Ordinance, and shall be considered
part of the Zoning Ordinance for purposes of
administration and appeals under state law. If
any provision of this ordinance differs or
appears to conflict with any provision of the
Zoning Ordinance or other ordinance or
regulation, the provision imposing the greater
restriction or more stringent standard shall be
controlling.
  • requiring that new and substantially-improved or
    damaged buildings be elevated or constructed to
    resist flood damages
  • prohibiting new development or substantial
    improvements that would increase flood heights in
    designated floodways and
  • guiding future development away from the SFHA.

2) prohibit new development or substantial
improvements that would increase flood heights in
designated floodways
12
3) guide future development away from flood
hazard areas.
EXAMPLE The Conway Zoning Ordinance provides
that within the Floodplain Conservation District,
only agricultural and residential accessory uses,
and sealed public water supplies are permitted
some special exception uses are also permitted,
none of which involve residential or commercial
use. In addition, expansions of existing
buildings or septic systems are not permitted,
and under no circumstances shall the flood
elevation in the Regulatory Floodway be allowed
to rise.

    (according to NFIP definition) anywhere in town.
  • Proposed development must be reviewed for
    compliance with other state or federal permits.
  • Proposed building sites must be reasonably safe
    from flooding. If the site is flood-prone
  • measures must be taken to anchor the building
  • materials must be used that are resistant to
    flood damage
  • methods of construction must be used that
    minimize flood damage and
  • utilities must be designed or located so as to
    prevent water from entering or accumulating.
  • Subdivision and site plan review proposals must
    be reviewed to determine whether they are
    reasonably safe from flooding.
  • Within flood-prone areas new and replacement
    water and sewer systems must be designed to
    minimize or eliminate the infiltration of
    floodwaters and discharges from the system into
    floodwaters.

24
B Ordinance Requirements
(No BFEs or Floodway Data)
  • All of the requirements of an a ordinance must
    be met (except for requiring a permit for
    development anywhere in town) in addition to
  • Base flood elevation data for all
    development proposals for land greater than
    50 lots or 5 acres, whichever is the lesser,
    must be provided by applicant.
  • Available floodway data will be reasonably
    utilized as criteria for compliance with
    elevation and/or floodproofing requirements.
  • Adjacent communities and the State NFIP
    Coordinator must be notified of any water
    course alterations.
  • Manufactured homes must be elevated and
    anchored.

25
C Ordinance Requirements
(BFEs, but no Floodway)
All of the requirements of a b ordinance must
be met, in addition to
  • The lowest floor of all residential structures
    must be elevated to or above the BFE.
  • Non-residential structures must either be
    elevated or floodproofed to at least one foot
    above BFE.
  • The design and construction methods must be
    certified by engineer or architect.
  • Fully enclosed areas below the lowest floor
    may only be used for parking, building access,
    and storage, and must be designed to
    automatically equalize hydrostatic flood forces.
  • Until a regulatory floodway is designated, no
    development in any A Zone can cause an increase
    in base flood elevation of more than one foot
    anywhere in the town.
  • Recreational vehicles, if left on a site for
    more than 180 consecutive days, or are not
    licensed and ready for highway use, must comply
    with all requirements for manufactured homes.

26
D Ordinance Requirements (BFEs and Floodway)
  • All of the requirements of a c ordinance must
    be met, in addition to
  • There may be no encroachment into the
    regulatory floodway that would cause any
    increase in the base flood elevation.

27
E Ordinance Requirements (A Zones with
Elevations and Velocity Zones)
  • Must meet all the requirements of a d
    ordinance, in addition to
  • All new construction must be located landward
    of the reach of the mean high tide and be at or
    above the BFE.
  • New construction and substantial improvements
    can not be elevated on fill, but only on
    pilings or columns, which must be anchored.
  • The space below the lowest floor must be free
    of obstructions or constructed with breakaway
    walls, open wood latticework, etc.

28
Minimum Requirements for Residential Structures
  • Must be
  • built at or above the BFE.
  • adequately anchored to prevent floatation,
    collapse, or lateral movement
  • constructed with materials resistant to flood
    damage

Minimum Requirements for Residential Structures
  • Must be
  • constructed by methods and practices that
    minimize flood damages and
  • constructed with service facilities (utilities)
    designed or located so as to prevent flood
    damage.

33
Minimum Requirements for Manufactured Homes
  • Must be
  • elevated to or above the BFE
  • on a permanent foundation and
  • adequately anchored to prevent floatation,
    collapse, or lateral movement.

34
(No Transcript)
35
There are different standards for construction in
coastal areas for example, fill may not be used
to elevate a structure only piers or pilings
are acceptable.
36
Minimum Requirements for Non-Residential
Structures
Must meet same requirements as residential,
except that instead of being elevated, the
building may be below the BFE, provided that
  • the structure is floodproofed to a minimum of
    one (1) foot above the BFE
  • the structural components are capable of
    resisting hydrostatic and hydrodynamic loads and
    the effects of buoyancy and
  • that the design and construction methods are
    certified by a registered professional engineer
    or architect that they meet NFIP-accepted
    standards.

37
Floodproofing techniques ensure that
  • walls are watertight

38
  • utilities are protected from flood damage

39
Examples of Floodproofing/Flood-Resistant
Materials

  • structural components can resist hydrostatic and
    hydrodynamic loads and effects of buoyancy

41
SUBDIVISION SITE PLAN REVIEW REQUIREMENTS
This is the language that needs to appear in any
local Subdivision and Site Plan Review Regulation
1. The Planning Board shall review the proposed
development to assure that all necessary permits
have been received from those governmental
agencies from which approval is required by
Federal or State law. 2. The Planning Board shall
require that all subdivision or site plan
proposals greater than 50 lots or 5 acres,
whichever is the lesser, shall include within
such proposals Base Flood Elevation data (i.e.,
floodplain boundary and 100-year flood
elevation). 3. The Planning Board shall require
the applicant to submit sufficient evidence
(e.g., construction drawings, grading and land
treatment plans) so as to allow a determination
that a. all such proposals are consistent with
the need to minimize flood damage b. all
public utilities and facilities are located and
constructed to minimize or eliminate flood
damage and c. adequate drainage is provided so
as to reduce exposure to flood hazards.

    Applications

FIRST Determine the location of the subject
property relative to the floodplain - based on
information provided by the applicant. In other
words, LOOK AT THE MAPS, and ask the question
Is this property/structure in the floodplain?

FEMA offers an on-line tutorial on reading and
understanding flood maps and studies _at_
www.fema.gov/mit/tsd/ot_firm.htm.
44
HOW TO READ THE FEMA MAPS
Key Elements of the Legend
  • A-Zone Designations subject to 100-year base
    flood.
  • V Zones Velocity zone, applies only to coastal
    areas
  • Floodway the river channel and adjacent land
  • X Zone (B Zone on older maps) subject to
    500-year flood
  • X Zone is all other (the white area) C Zone on
    older maps
  • BFE Line base flood elevation measured in feet
    above sea level
  • Cross Section Line graphical depiction of
    stream and floodplain
  • Reference Mark surveyed bench marks
  • River Mile stations along the stream
  • Refer to Flood Insurance
    Study

Key Elements of the Panel
Type of Map Community Name
Community Number Panel Number Map
Number Effective Date
45
Example 1 With BFEs
  • Check Map Index for Applicable Panel
  • Determine location of the property

46
  • Use an engineers scale with the map scale to
    determine whether the building site is in the
    floodplain.
  • If so, find the nearest BFE and, if applicable,
    the Cross Sectional data on the map.

x
47
5. Use the Flood Insurance Table from the Study
to determine exact BFE for the closest cross
section(s).
x
48
6. When available, use the Elevation Reference
Marks for specific BFEs.
RM 13
49
Example 2 With no BFEs
Methods for Developing BFEs
  • Detailed Methods
  • QUICK-2
  • Computer Models

Textbook resource on A-Zone issues and a tutorial
for learning Quick-2. A disk with the Quick-2
program is included with the publication.
50
Simplified Method (Examples)
  • If the stream forms a boundary between towns, the
    other town may have elevation data.
  • Check with USACOE, USDA or USGS for any studies
    they may have or know of.
  • If the stream is near a bridge or culvert, the
    town or DOT may have elevation data.
  • If there is a dam on the stream, there may be
    elevation data related to it.
  • If there is a subdivision near the site, the
    developer may have submitted base flood data as
    part of the subdivision approval.
  • Use contour elevation extrapolated from a best
    fit analysis of the floodplain boundary when
    overlayed onto a USGS Quad or other topographic
    map.
  • Use the elevation of the ground at the
    intersection of the floodplain boundary and a
    line perpendicular to the shoreline that passes
    along the ground through the site of the proposed
    building.
  • Use historical records or the flood of record.
  • Compare the shaded area of the FIRM with the
    contours on a USGS Quad map or any other
    topographical map that more accurately represents
    the existing land form of the area. Determine
    which contour best approximates the boundary of
    the shaded area and use that contour and the
    elevation as the regulatory flood elevation.
  • If no flood elevation data are available from the
    sources noted above, it is recommended that the
    lowest floor be elevated at least 2 feet above
    the highest grade adjacent to the building site.

51
This example can apply both to AO Zones, where
there also are no BFEs, but instead depth of
shallow flooding, and to Approximate A Zones.

1 While most towns have a building permit
system in place, and would not necessarily use a
separate checklist or application form for
floodplain issues, bear in mind that the NFIP
regulations call for a permit for all development
in a floodplain. This form can serve as a useful
reminder of all applicable regulations. If a
separate form is not used, however, the building
permit application should at least ask the
question Is the property and/or structure
located in a floodplain or a floodway?

53
DETERMINE WHAT ADDITIONAL INFORMATION MIGHT BE
REQUIRED, FOR EXAMPLE
  • ADDITIONAL INFORMATION REQUIRED
  • Elevation Certificate (residential) and/or
    Floodproofing Certificate (non-residential).
    ____
  • Site Plan showing the location of all existing
    and proposed structures, 100-year floodplain
    boundary, and floodway boundary, if applicable.
    ____
  • Development plans, drawn to scale, including
    where applicable details for anchoring
    structures, elevation of lowest floor (including
    basement), detail of floodproofing of utilities
    located below the first floor, and details of
    enclosures below the first floor. ____
  • If the subdivision is greater than 50 lots or 5
    acres, the applicant must provide the Base Flood
    Elevation in the subdivision plans.
    ____
  • Plans showing the extent of watercourse
    relocation and/or landform alteration.
    ____

54
SUBSTANTIAL DAMAGE/IMPROVEMENT
  • The Basic Rule If the cost to repair or improve
    a structure exceeds 50 of the market value prior
    to the improvements, it must be brought up to
    current NFIP standards.

55
Examples of Substantial Repairs Residential
Example 2 - Substantial Addition The entire
structure must be elevated.
Example 1 - Minor Addition Only the addition
must be elevated.
Example 3 -Vertical Addition Elevated only if
substantial.
Example 4 - Minor Addition to Post-FIRM (after
December 31, 1974)
56
Examples of Substantial Repairs Non-Residential
Example 1 Only the addition must be either
elevated or floodproofed.
Example 2 The entire structure must be
elevated or floodproofed.
57
Methods of Estimating Market Value, Improvement
Costs and/or Damage Value
  • Independent appraisals by a professional
    appraiser not a Realtor
  • Itemized cost estimates from licensed contractors
    or professional estimators
  • Estimates from NFIP claims data
  • Marshall and Swift (actual cash value)
  • For a gross estimate use adjusted tax value

FEMA-213, May 1991
58
ELEVATION CERTIFICATES
  • Must be filed with an application to either
    construct or substantially improve a building in
    the special flood hazard area.
  • The Elevation Certificate is used to
    demonstrate either that
  • 1) a building will be constructed at or above
    the Base Flood Elevation or
  • 2) an existing building shown in the SFHA is
    actually out of it because of the lowest floor
    elevation.
  • The elevation data must be certified by a
    professional surveyor, engineer or architect.

61
FLOODPROOFING CERTIFICATES
  • Must be filed for non-residential structures
    and/or utilities.
  • Used to demonstrate compliance with FEMA-approved
    floodproofing techniques.
  • Must be completed by a professional engineer or
    architect.

62
NO-RISE CERTIFICATION
NO-RISE CERTIFICATION This is to certify that
I am a duly qualified registered professional
engineer licensed to practice in the State of New
Hampshire. It is further to certify that the
attached technical data supports the fact that
proposed (Name of Development) will not impact
the 100-year flood elevations, floodway
elevations, or floodway widths on (Name of
Stream) at published sections in the Flood
Insurance Study for (Name of Community) dated
_______________ and will not impact the 100-year
flood elevations, floodway elevations, or
floodway widths at unpublished cross-sections in
the vicinity of the proposed development. Attached
are the following documents that support my
findings _______________________________ ________
_______________________ Date____________________
Signature________________________ Title_______
_____________________ SEAL
  • The No-Rise Certification is used to document
    that proposed development in the floodway does
    not affect flood elevations.
  • Must be certified by a professional engineer.
  • NOTE
  • This is not a FEMA form, but one developed by a
    state agency to facilitate the review process.

63
V-ZONE CERTIFICATION
  • Used for construction in coastal areas.
  • Is used for either residential or non-residential
    development.
  • Used to demonstrate compliance with FEMA-approved
    design and construction techniques specific to V
    Zones.
  • Must be completed by a professional engineer or
    architect.

64
MAP REVISIONS
  • FOUR WAYS TO CHANGE A FEMA MAP
  • 1. A Restudy is a new Flood Insurance Study
    for some or all of the community.
  • 2. A Limited Map Maintenance Project is a
    small-scale restudy, frequently used for studies
    in unnumbered A Zones.
  • 3. An Amendment is used to remove a structure
    or an area from the SFHA that is higher than the
    flood elevation, or that is shown to be outside
    the SFHA.
  • LOMA Letter of Map Amendment
  • LOMR-F Letter of Map Revision based on Fill
  • CLOMA CLOMR-F are conditional letters of
    change for proposed projects.
  • 4. A Revision is an actual change to the
    boundaries of the floodplain based on changes on
    the ground (such as fill), bridges, culverts, or
    new data.
  • NOTE Amendments and Revisions are the
    responsibility of the property owners.
    Restudies and LMMPs are the responsibility of
    the community and FEMA.

A Note About Disaster Assistance Why
have flood insurance? If there is a disaster,
the federal government will provide assistance.
  • Federal Disaster Assistance is available only if
    the disaster is Presidentially declared. (Fewer
    than 50 of them are.)
  • Certain types of Federal Disaster Assistance will
    soon be available only in those communities that
    have an approved Hazard Mitigation Plan.
  • Some types of Disaster Assistance are only
    available to communities that participate in the
    NFIP.
  • What is available is in the form of low-interest
    loans and grants to very low income residents.

Flood insurance pays even if there is no
Presidentially-declared Disaster.

COMMUNITY RATING SYSTEM
  • Implemented in 1990 to encourage floodplain
    management activities that exceed the minimum
    standards.
  • Flood insurance rates for properties in the SFHA
    are adjusted to reflect the reduced flood risk
    resulting from implementation of the CRS
    activities.
  • Points are earned for various activities, putting
    a community into a Class based on points earned.

    understanding of the NFIP and
  • (3) to offer assistance in implementing flood
    loss measures or other aspects of administering
    the Program.
  • Conducted by staff from the Office of State
    Planning, the Bureau of Emergency Management, the
    Regional Planning Commissions, and/or FEMA staff.
