SECTION C Building Elevation Information Item 1. The Elevation Certificate uses a building's reference level as the point for measuring its elevation. Pages 5 and 6 of this Elevation Certificate package contain a series of eight diagrams of various building types that are to be used to help determine the reference level. Choose the diagram that best represents this building, record the diagram number, and use the indicatetl reference level to measure the elevation as requested in Items 2a-d. Item 2. Depending on the property location's FIRM Zone, complete Item 2a. 2b, 2c, or 2d. Use the reference level shown in the appropriate building diagram as the point of measurement. As shown in the diagram on the back of the Certificate. for all A Zones, the elevation should be measured at the top of the reference level floor. For all V Zones, the elevation should be measured at the bottom of the lowest horizontal structural member of the reference level floor. Reporting of elevations in Items 2a and 2b should be to the nearest tenth of a foot, or alternatively, unless prohibited by state or local ordinance, the reference level elevation may be "rounded down" to the nearest whole foot ("rounding up" is prohibited). Item 2(a). For structures located in FIRM Zones A7-A30, AE. AH, and A (with BFE's), record the elevation (to the nearest tenth of a foot) of the top of the floor itlentrfied as the reference level in the applicable diagram. Item 2(b). For structures located in FIRM Zones V1-V30, VE, and V (whh BFE's), record the elevation (to the nearest tenth of a foot) of the bottom of the lowest horizontal structural member of the floor identified as the reference level in the applicable diagram . Item 2(c). For structures located in FIRM Zone A (without BFE's), record the height (to the nearest tenth of a foot) of the top of the floor indicated as the reference level (from the applicable diagram) above or below the highest adjacent grade immediately next to the building. Item 2(d). For structures located in FIRM Zone AO, the FIRM will show the base flood depth. For locations in FIRM Zone AO record the height (to the nearest tenth of a foot) of the top of the floor identified as the reference level (from the applicable diagram) above or below the hignest adjacent grade immediately next to the building. For post-FIRM buildings, the community's floodplain management ordinance requves that this value equal or exceed the base flood depth provided on the FIRM. For those few communities where this base flood depth is not available, the community will need to determine if the lowest floor is elevated in accordance with their floodplain management ordinance. Item 3. Record the vertical datum system used in identifying the reference level elevations for all buildings. If the datum used in measuring the elevations is different than that used on the FIRM, then convert the elevations in Items 2a-d to the datum used on the FIRM, and show the conversion equation under the Comments section on Page 2. Item 4. Indicate it the elevation reference mark used appears on the FIRM. Reference marks other than those shown on the FIRM may be used for elevation determinations. In areas experiencing ground subsitlence, the most recently adjusted reference mark elevations must be used for reference level elevation determinations. Item 5. Indicate if the reference level used in making the elevation measurement is based on actual construction or construction drawings. Construction drawings should only be used if the building does not yet have the reference level tloor in place, in which case the Elevation Certificate will only be valid for the building during the course of construction. Apost-construction Elevation Certificate will be needed once construction is complete. Item 6. Record the elevation measurement of the lowest grade adjacent to the building (to the nearest tenth'of a toot). Adjacent grade is defined as the elevation of the ground, sidewalk, patio. deck support, or basement entryway immediately next to the structure. This measurement should be to the nearest tenth of a toot i} this Certificate is being used to support a request for a LOMA/LOMR. SECTION D Community Information Completion of this section may be required by the community in ortler to meet the minimum floodplain management requirements of the NFIP. Otherwise, completion of this section is not required. Item 1. The community's floodplain management ordinance requires elevation of the building's "lowest floor" above the BFE. For the vast majority of building types. the reference level and the lowest floor will be the same. If the community determines that there is a discrepancy, record the elevation of the lowest floor. Item 2. Enter date. These terms are defined by local ordinance. SECTION E Certiflcalion Complete as indicated. The Elevation Certificate may only be signed by a land surveyor, engineer, or architect who is authorized by state or local law to certify elevation information when the elevation information for Zones A7-A30, AE, AH, A (with BFE's), V1-V30. VE, and V (with BFE's) is required. Community officials who are authorized by local law or ordinance to provide floodplain management information may also sign this cenihcation. In the case of Zones AO and A (without BFE's), a building official, a property owner, or an owner's representative may sign this certification. Certification is normally to the information provided in Sections B and C. If the certifier is unable to certify to the selection of reference level diagram 6, 7 or 8 (Section C, Item 1), e.g., because of difficulty in obtaining construction or building use information needed to determine the Distinguishing Feature(s), the certifier must list the Feature(s) excluded from the certification under Comments on Page 2. The diagram number used for the Reference level must still be entered in Section C. Item 1. Page 4
