House Plans for Flood Zones

We often meet with clients who have purchased property in flood zones who really don’t understand what flood zone they are in, and the affect this will have on the design of there dream home.
There are two flood zone that in the coastal high hazard areas that need to be addressed. The first is the V zone this is the area that most of your typical beachfront or island home fit into. The second flood zone is the A zone which would be your typical coastal flood area, homes that are further inland but still have a potential for flooding from high waters.





A home located in a V zone has to be designed to take the most punishing effects Mother Nature can dish out and survive somewhat intact. Homes in V zones have the foundation designed to allow fast moving water, debris and waves to flow below the elevated home. This is done by having the home elevated on piles, columns or piers which give minimal resistance to floodwaters. This will allow the water to flow completely through the bottom of the elevated structure.

House plans for flood zones

A home located in a V zone has to be designed to take the most punishing effects Mother Nature can dish out and survive somewhat intact. Homes in V zones have the foundation designed to allow fast moving water, debris and waves to flow below the elevated home. This is done by having the home elevated on piles, columns or piers which give minimal resistance to floodwaters. This will allow the water to flow completely through the bottom of the elevated structure.
This is why homes located in a V zone will typically have wood louvers, lattice or screening around the bottom perimeter. The perimeter screening is more commonly known as “breakaway” panels. These breakaway panels are designed to break a way from the home and leave only the structural members in the event of a flood.
Home that are in an A zone have far less restraining requirements when it comes to foundation design. Typically A zones will require the automatic entry and exit of floodwaters through flood vents. This will allow the floodwaters to reach equal levels on both sides of the wall. Homes located in A zones are typically not exposed to high water velocity or waves. They are usually located inland but still in close proximity to a waterway. In the foundation design your perimeter can use virtually any material that will allow for the integration of the flood vents into the foundation wall.
