What is the flood risk of your Nashville home or business area?
9/9/2015 (Permalink)
A flood can happen just about anywhere with rainfall. According to Floodsmart.gov, a flood is a general and temporary condition where two or more acres of dry land or two or more properties are inundated by water or mudflow. The site advises that floods are the #1 natural disaster in the United States. Floods can happen due to multiple different factors such as: rainfall, river-flow, topography, flood-control measures, and changes due to building and development. Areas are marked as having different levels of flood risks. There are high-risk, moderate-to-low risk, and undetermined-risk areas. You can check the flood risk of your area by checking the flood map at Fema.gov (https://msc.fema.gov/portal).
High-risk
High-risk areas, also known as special flood hazard areas, have at least a one in four chance of flooding during a 30-year mortgage. Any homes or businesses in these areas that have loans from federally regulated companies are required to have flood insurance. On the flood map, these zones are marked as letters A and V.
Moderate-to-low risk
Moderate-to-low risk areas, also known as non-special flood hazard areas, carry nearly 20% of flood insurance claims and receive one-third of disaster assistance for recovery. Flood insurance is not required in these areas, but it is highly recommended for all property owners and renters. These areas are shown with the letters B, C, or X in the flood map.
Undetermined-risk
Since flood risks are possible anywhere, these areas are not completely safe from floods, but have not had flood analysis conducted in them. These areas are shown on the flood map with a letter D.
