Under the NFIP, a minimum of two openings are required for every enclosed area or crawlspace. The openings shall provide a total net area of not less Proper building diagram selection is essential for than one square inch for every square foot area determining the elevations that must be measured to properly complete the EC enclosed, excluding any bars, louvers, or other covers Take photographs that capture the characteristics that of the opening. support the building diagram 17 18 Flood Openings Engineered Flood Openings Individual Engineered Flood Openings Certification or an Evaluation Report issued by the International Code Council Evaluation Service (ICC ES) must be submitted to document that the design of the openings will allow for automatic equalization of hydrostatic flood forces on exterior walls. 20 STARR ‐ Strategic Alliance for Risk Reduction 3
Elevation Certificates Training 11/14/2013 More About Flood Openings More About Flood Openings A window, a door, or a garage door is not considered an opening; but openings may be installed in doors. The bottom of the openings must be no higher than one Subtract area of grates, louvers, or grills foot above the higher of the exterior or interior grade or floor immediately below the opening. For more guidance on openings, see NFIP Technical Bulletin 1 – ‘Openings in Foundation Walls and Walls of Enclosures.’” 21 22 Attached Garages Section B – FIRM Information Can be completed by the community or homeowner Verify ALL FIELDS, especially Community Number, Separate foundations Map/Panel numbers/dates and BFE Can be considered a separate structure Can be insured separately Check elevation datum used (NGVD29/NAVD88) Common wall Single structure One insurance policy Could also have a separate EC 24 B2 & B3 B2 & B3 B1 B1 B4 & B4 & B5 B5 B7 B7 B6 B6 25 27 STARR ‐ Strategic Alliance for Risk Reduction 4

Zone AE or A1-99—Use Flood Insurance Study Item B-10: Where did the BFE come from, especially in unnumbered “A” zones Zone AO—Use depth number on the FIRM/FIS Zone A—if no BFE available, enter “N/A” and complete Estimating BFE’s between the wavy lines on the FIRM Section E, unless applying for a LOMA or LOMR-F Zone VE—Use the FIRM and FIS 28 29 C1 – Basis for Elevations Section C – Building Elevations MUST be completed by a surveyor or engineer “Finished construction” means all machinery and New! Ne w! equipment are installed and final grading is completed NO Blanks – use “N/A” if there is nothing to measure Indicate if elevations are From construction drawings For building under construction Finished construction – only after all machinery and equipment are installed and grading around structure is complete 31 32 Section C - Benchmarks Section C – Building Elevations • Each benchmark in a network has a unique N/A identifier • The National Geodetic Survey uses the Permanent Identifier Enter measurements to nearest tenth of a foot (PID) to uniquely identify This section is required for Zones A1-30, AE, AH or A (with each benchmark. BFE) and for VE zones • Most other networks will This section is not required for Zones AO or A (without BFE), assign a similar identifier except to support an application for LOMA or LOMR-F 33 34 STARR ‐ Strategic Alliance for Risk Reduction 5
