8/1/2023 – When are Flood Vents required?

Response From Floodproofing.com: The NFIP Regulations and Building Codes require that any residential building constructed in Flood Zone Type A have the lowest floor, including basements, elevated to or above the Base Flood Elevation (BFE). Enclosed areas (enclosures) are permitted under elevated buildings provided that they meet certain use restrictions and construction requirements such as the installation of flood vents to allow for the automatic entry and exit of flood waters. This wet floodproofing technique is required for residential buildings. Commercial buildings have the option to wet floodproof, which can be more cost-effective compared to dry floodproofing.

8/1/2023 – What is the difference between Engineered and non-engineered openings?

Response From Floodproofing.com: Engineered openings have been designed and tested as flood vents and are given a flood coverage rating based on performance. For example, SMART VENTS are ICC-ES Certified for 200 sq. feet of flood protection per 16” x 8” vent.

Non-engineered openings have not gone through any of the required testing, or any sort of flood testing for that matter, to qualify as an engineered flood vent and typically are solely intended for use as an air vent. Therefore, they are rated at the assumptive method of 1 net sq. inch of opening per 1 foot of enclosed area.
