Instructions for Completing

OMB Control Number: 1660-0008

the Elevation Certificate (Continued)

Expiration: 11/30/2018

SECTION C - BUILDING ELEVATION INFORMATION (SURVEY REQUIRED)

Complete Section C if the building is located in any of Zones A1-A30, AE, AH, A (with BFE), VE, V1-V30, V (with BFE), AR, AR/A,

AR/AE, AR/A1-A30, AR/AH, or AR/AO, or if this certificate is being used to support a request for a LOMA or LOMR-F. If the building is

located in Zone AO or Zone A (without BFE), complete Section E instead. To ensure that all required elevations are obtained, it may be

necessary to enter the building (for instance, if the building has a basement or sunken living room, split-level construction, or machinery

and equipment).

Surveyors may not be able to gain access to some crawlspaces to shoot the elevation of the crawlspace floor. If access to the

crawlspace is limited or cannot be gained, follow one of these procedures.

• Use a yardstick or tape measure to measure the height from the floor of the crawlspace to the "next higher floor," and then subtract

the crawlspace height from the elevation of the "next higher floor." If there is no access to the crawlspace, use the exterior grade

next to the structure to measure the height of the crawlspace to the "next higher floor."

• Contact the local floodplain administrator of the community in which the building is located. The community may have documentation

of the elevation of the crawlspace floor as part of the permit issued for the building.

• If the property owner has documentation or knows the height of the crawlspace floor to the next higher floor, try to verify this by

looking inside the crawlspace through any openings or vents.

In all 3 cases, provide the elevation in the Comments area of Section D on the back of the form and a brief description of how the

elevation was obtained.

Item C1. Indicate whether the elevations to be entered in this section are based on construction drawings, a building under construction,

or finished construction. For either of the first 2 choices, a post-construction Elevation Certificate will be required when construction is

complete. If the building is under construction, include only those elevations that can be surveyed in Items C2.a-h. Use the Comments

area of Section D to provide elevations obtained from the construction plans or drawings. Select "Finished Construction" only when all

machinery and/or equipment such as furnaces, hot water heaters, heat pumps, air conditioners, and elevators and their associated

equipment have been installed and the grading around the building is completed.

Item C2. A field survey is required for Items C2.a-h. Most control networks will assign a unique identifier for each benchmark. For

example, the National Geodetic Survey uses the Permanent Identifier (PID). For the benchmark utilized, provide the PID or other unique

identifier assigned by the maintainer of the benchmark. For GPS survey, indicate the benchmark used for the base station, the

Continuously Operating Reference Stations (CORS) sites used for an On-line Positioning User Service (OPUS) solution (also attach the

OPUS report), or the name of the Real Time Network used.

Also provide the vertical datum for the benchmark elevation. All elevations for the certificate, including the elevations for Items C2.a-h,

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

used for the BFE entered in Item B9 and indicate the conversion software used. Show the datum conversion, if applicable, in the

Comments area of Section D.

For property experiencing ground subsidence, the most recent reference mark elevations must be used for determining building

elevations. However, when subsidence is involved, the BFE should not be adjusted. Enter elevations in Items C2.a-h to the nearest tenth

of a foot (nearest tenth of a meter, in Puerto Rico).

Items C2.a-d Enter the building elevations (excluding the attached garage) indicated by the selected building diagram (Item A7) in Items

C2.a-c. If there is an attached garage, enter the elevation for top of attached garage slab in Item C2.d. (Because elevation for top of

attached garage slab is self-explanatory, attached garages are not illustrated in the diagrams.) If the building is located in a V zone on the

FIRM, complete Item C2.c. If the flood zone cannot be determined, enter elevations for all of Items C2.a-h. For buildings in A zones,

elevations a, b, d, and e should be measured at the top of the floor. For buildings in V zones, elevation c must be measured at the bottom

of the lowest horizontal structural member of the floor (see drawing below). For buildings elevated on a crawlspace, Diagrams 8 and 9,

enter the elevation of the top of the crawlspace floor in Item C2.a, whether or not the crawlspace has permanent flood openings (flood

vents). If any item does not apply to the building, enter "N/A" for not applicable.
