SECTION C – BUILDING ELEVATION INFORMATION (SURVEY REQUIRED) (Continued)
<br />In all three cases, use the Comments area of Section D to provide the elevation and a brief description of how the elevation was obtained.
<br />Note: If any item does not apply to the building, enter "N/A" for not applicable.
<br />Item C1. Indicate whether the elevations to be entered in this section are based on construction drawings, a building under construction, or
<br />finished construction. For either of the first two choices, a post-construction Elevation Certificate will be required when construction is
<br />complete. If the building is under construction, include only those elevations that can be surveyed in Items C2.a–h. Use the Comments
<br />area of Section D to provide elevations obtained from the construction plans or drawings. Select "Finished Construction" only when all
<br />M&E such as furnaces, water heaters, heat pumps, air conditioners, and elevators and their associated equipment have been installed and
<br />the grading around the building is completed.
<br />Item C2. A field survey is required for Items C2.a–h. Most control networks will assign a unique identifier for each benchmark. For
<br />example, the National Geodetic Survey uses the Permanent Identifier (PID). For the benchmark utilized, provide the PID or other unique
<br />identifier assigned by the maintainer of the benchmark. For GPS survey, indicate the benchmark used for the base station, the
<br />Continuously Operating Reference Stations (CORS) sites used for an Online Positioning User Service (OPUS) solution (also attach the
<br />OPUS report), or the name of the Real Time Network used.
<br />Also provide the vertical datum for the benchmark elevation. All elevations for the certificate, including the elevations for Items C2.a–h,
<br />must use the same datum on which the BFE is based. Show the conversion from the field survey datum used if it differs from the datum
<br />used for the BFE entered in Item B9 and indicate the conversion software used. Show the datum conversion, if applicable, in the
<br />Comments area of Section D.
<br />For property experiencing ground subsidence, the most recent reference mark elevations must be used for determining building
<br />elevations. However, when subsidence is involved, the BFE should not be adjusted.
<br />Note: Enter elevations in Items C2.a–h to the nearest tenth of a foot (nearest tenth of a meter, in Puerto Rico); if data is surveyed to the
<br />nearest hundredth, round to the nearest tenth.
<br />Item C2.a. Enter the elevation measured at the top of the bottom floor (excluding the attached garage) indicated by the selected Building
<br />Diagram (Item A7). For buildings elevated on a crawlspace, Building Diagrams 8 and 9, enter the lowest elevation of the top of the
<br />crawlspace floor in Item C2.a, whether or not the crawlspace has permanent flood openings (flood vents).
<br />Item C2.b. For Building Diagrams 2A through 9 in any flood zone, including Zones B, C, X, and D, enter the elevation measured at the top
<br />of the next higher floor (excluding the attached garage) indicated by the selected Building Diagram (Item A7). For buildings requiring more
<br />than two floors or levels to be surveyed, such as those with multiple floors or multi-level enclosures, enter the additional surveyed
<br />elevations and floor descriptions in the Section D Comments, and clarify which floors are entered as Item C2.a and C2.b.
<br />Item C2.c. For floodplain management compliance, this elevation is required for all Building Diagrams 5 and 6 in V Zones in areas
<br />seaward of the LiMWA, and in other areas regulated for coastal flooding hazards. Enter the elevation measured at the bottom of the lowest
<br />horizontal structural member of the floor indicated by the selected Building Diagram (Item A7) or the figure below. This elevation can be
<br />entered for Building Diagrams 5 and 6 in any flood zone, including Zones B, C, X, and D. For Building Diagrams other than 5 and 6 (if
<br />applicable), enter the C2.c elevation as indicated in the figure below. If this item does not apply to the building, enter "N/A" for not
<br />applicable.
<br />Item C2.d. If there is an attached garage, enter the lowest elevation for top of attached garage slab. (Because elevation for top of attached
<br />garage slab is self-explanatory, attached garages are not illustrated in the Building Diagrams.)
<br />Item C2.e. Enter the lowest platform, floor, or ground elevation supporting the lowest electrical, heating, ventilation, plumbing, and air
<br />conditioning M&E and other utilities servicing the building, which may be located in an attached garage or enclosure or on an open utility
<br />platform. Note that elevations for the M&E items are required regardless of their location. Local floodplain management officials are
<br />required to ensure that all new M&E servicing the building are protected from flooding. Thus, local officials may require that elevation
<br />information for all M&E, including ductwork, be documented on the Elevation Certificate. If the M&E is mounted to a wall, pile, etc., enter
<br />the platform elevation of the M&E. Indicate the lowest M&E type and its general location (e.g., on floor inside garage, on platform affixed to
<br />exterior wall) in the Comments area of Section D or Section G, as appropriate.
<br />Note: For more guidance on floodplain management compliance for utilities, including M&E, refer to FEMA P-348, Protecting Building
<br />Utility Systems from Flood Damage. The list of M&E and the elevation requirements for documenting floodplain management compliance
<br />are different than the NFIP insurance M&E discount eligibility considerations. See Section H Instructions for additional information.
<br />Land surveyors may not be able to gain access to some crawlspaces to shoot the elevation of the crawlspace floor. If access to the
<br />crawlspace is limited or cannot be gained, follow one of these procedures.
<br />• Use a yardstick or tape measure to measure the height from the floor of the crawlspace to the "next higher floor," and then subtract
<br />the crawlspace height from the elevation of the "next higher floor." If there is no access to the crawlspace, use the exterior grade
<br />next to the structure to measure the height of the crawlspace to the "next higher floor."
<br />• Contact the local floodplain management official of the community in which the building is located. The community may have
<br />documentation of the elevation of the crawlspace floor as part of the permit issued for the building.
<br />• If the property owner has documentation or knows the height of the crawlspace floor to the next higher floor, try to verify this by
<br />looking inside the crawlspace through any openings or vents.
