FEMA allows two types of flood vents to make your home FEMA compliant. There are Non-Engineered flood vents and Engineered flood vents. Both have advantages and disadvantages. We have published an article titled "How to Protect Your Home With FEMA Compliant Flood Vents" that will help you better understand FEMAs rules on flood vents. If you want to learn more about flood vents you can refer to FEMA's TB - 1 (2008). Also we have flyers that will give you more details about FEMA rules and requirement for Non-Engineered flood vents and Engineered flood vents.
We hope this blog helps you better understanding the difference between Flood Vents - Engineered or Not! Please contact us if you need additional information. We have a Certified Floodplain Manager on staff his name is Chris Qualtieri and he can be reached at 757-274-9989.
