How To Build An Above Ground Storm Shelter? Clearly Explained!

According to the experts at FEMA, an above-ground storm shelter is particularly suitable for locations with a high water table. The guidelines state that a detached storm shelter should not be more than 150 feet away from a water source.

In addition, the shelter should be able to withstand a wind speed of at least 25 miles per hour and a depth of up to 1,000 feet. The shelter also must have a minimum floor area of 2,500 square feet, which is approximately the same size as a standard two-bedroom apartment.

The FEMA guidelines also state that the minimum size of a shelter for a family of four is two bedrooms, a bathroom, and an enclosed living area. However, it is important to note that these guidelines do not apply to single-family homes.

For example, if a single family home is located in a flood plain, then it would not be required to meet FEMA‘s guidelines.
