“A8 & A9” Iden@fying Non-‐Compliance
• EC shows that the enclosed space is short 439 sq.in of flood ven;ng coverage • Air vents were miss-‐rated as well, but Surveyor was accurate • NFIP Lowest rated floor becomes the enclosure floor below the BFE

Sec@on “C” Eleva@ons Iden@fying Non-‐Compliance
• Because the LAG (f) is 10.8” lower then the Top of BoYom Floor (e) this space is sub-‐grade
• f) Cannot be greater then e) • Lowest rated floor is 200.3 which equals a -‐4
(BFE 204.5 – 200.3)
