FEMA and its mapping partners (states, communities, and private companies) make every effort to produce flood maps that accurately depict the flooding risk in a given geographic area. Even with recent technological advances that offer improvements in precision, the accuracy can vary depending on the technical data and the resources used to create them. Likewise, with development, population growth and flood mitigation efforts, flood hazard areas within a community change over the course of time, affecting the accuracy of the flood maps. In some communities, the effective maps date back to the 1970s, when the effort to produce flood maps for the entire country began. It is possible that these maps do not accurately reflect the current flood hazard areas for these communities.
