Requirements: The Basics
1 - Openings must be installed on foundation walls so water can flow unimpeded into and out of the tube without harming the integrity of the walls. The regulation is easy to remember: one inch opening square in the wall of the foundation for each square foot of surface in your home. For example, a crawl space of 2000 square feet require 2,000 square inches of opening. The number of openings flood, you should install depends on the size and type of ventilation to buy. (We will return.)
2 - Each space closed must have a minimum of two openings. If there are several areas closed within the walls of the foundation, each region must have at least two openings in the walls.
3 - flood vents should be below flood stage at work. The bottom opening shall not exceed 1 foot above One of these is greater: inside or outside just below the opening.
4 - All screens, railings, grids, fixed louvers or other coverings or devices should not block or impede the automatic circulation of water inside and outside the defined area.
Why Wind flooding required?
The purpose of flood vents (also called "gates" or "port flooding") is to reduce the damage caused by floods. These permanent openings to achieve this goal by allowing water flow into or out of the walls of a building's exterior of the foundation.
Why is it so important? In a flood situation, if the pressure water inside and outside your house can be treated quickly enough, the doors and windows can explode. In addition, this pressure can endanger the foundations and make your home safe to live, studies have shown that homes with sufficient openings to survive a flood, houses without ventilation such collapse.
Who needs flood Wind?
According to its website, the NFIP "requires flood vents for residential basements, crawl spaces, garages and other enclosed structures which are under the baseline against flooding (BFE) in the areas of special flood hazard. "BFE is the height of the flood base, so general in the feet, as regards national Vertical Datum of 1929 or other datum as specified.
If your house is not mortgaged, are not required by FEMA and NFIP regulations to have insurance against floods or flood vents. However, insurance against floods is recommended to protect your investment.

Second, if the water rises to his home, the mouths of flooding can reduce the risk of structural damage, which can be very costly to repair.
What kind of flood Wind If you install?
There are two types of vents to flood market: no engineering and design. vents Engineering controls are designed in such a way as to provide a more effective relief against floods and vents must be less installed.
The size of the opening of the engineering flood without ventilation is calculated by multiplying the width by the height of the opening. The size of the opening of the flood ventilation engineering is calculated using a mathematical formula that takes into account certain factors, the surface net and opening procedure. This form must be certified by an engineer. The main difference between the two types of flood vents is less than the flood openings in engineering are required to comply with the requirements of the NFIP. For example, a non-engineering 8 "x 16 "Wind is estimated at 128 square inches, while 8 of engineering" x 16 "is estimated at 200 square inches.
other design criteria and performance engineering for the openings are defined by the American Society of Civil Engineers:
1 - Openings are designed to perform so that the difference between water levels outside and inside should not exceed 1 foot on the basis of flood conditions.
2 - Engineering openings must not be less than 3 inches in any direction the plane of the wall. This requirement applies in the hole in the wall, the exclusion of any screen, grill, grill, vents, or devices that can be placed in or on the opening. This requirement applies opening of 3 inches into the hole in the wall no space between the bars, grilles or shutters.
In short: Numbers to remember
requirements of FEMA flood insurance cons to this:
1 - inch square the opening of a foundation wall per square foot of the house.
2 - Winds should be less than 12 inches above the ground.
3 - Two air vents area bounded on different walls.
That's it. Make sure you have adequate ventilation installed flood - Or do it yourself - then call your insurance against floods in order to obtain a reduction in their premiums. You can also enjoy the tranquility of know that you are not only compatible, you're more confident.
