The problem here in Maine is that for most of the State elevation data has not been remapped since the 1920’s when the United States Geological Survey completed a nation wide survey to determine elevations. So when mapping a floodplain it is important to be able to determine land elevations very accurately. Depth of water is measured in feet and may be as much as 30 feet above the normal high water mark of the river or stream. When the river floods it spreads out and inundates a large area. Challenges to Good Floodplain Mapping Good Elevation Dataįloodplains are called that because they tend to be wide and relatively flat. The latest version of the State of Maine Risk MAP Business Plan (dated March 2016) outlines the current State of Maine plan for assisting FEMA in implementing the Risk MAP program. Learn more about the goals and long term vision of Risk MAP, how the program works and what it means for you in the sections below. Each Risk MAP flood risk project is tailored to the needs of each community and may involve different products and services. Risk MAP provides high quality flood maps and information, tools to better assess the risk from flooding and planning and outreach support to communities to help them take action to reduce or mitigate flood risk. FEMA is working with federal, state, tribal and local partners across the nation to identify flood risk and help reduce that risk through the Risk Mapping, Assessment and Planning (Risk MAP) program. ![]() Not only is flooding one of the most common and costly disasters, flood risk can also change over time because of new building and development, weather patterns and other factors.
