The Federal Emergency Management Agency (FEMA) has identified more than 1,000 properties in Summit County as being located in a regulatory floodplain.

This designation has important implications related to flood insurance requirements, flood insurance rates, property sales and obtaining mortgages from federally regulated or insured lenders.

Flood Map Modernization

Beginning in 2003, FEMA undertook the Flood Map Modernization initiative (Map Mod) to improve and update the nation’s flood maps; the agency provided 92 percent of the nation’s population with digital Flood Insurance Rate Maps. The initiative laid the foundation for FEMA's Risk Mapping Assessment and Planning program.

Through Map Mod, FEMA used state-of-the-art technology and advanced engineering to increase the quality, reliability, and availability of flood hazard maps and data and employed a collaborative process to involve state, regional and local partners in mapping tasks. In addition to providing more accurate and up-to-date flood hazard information, Map Mod enhanced community officials’ and citizens’ decision-making and their ability to manage risks and other issues locally.

Summit County and the incorporated municipalities within the county adopted FEMA's new digital Flood Insurance Rate Maps (FIRMs) for their respective jurisdictions in November 2011.

Flood Map Revisions

Summit County and the towns of Breckenridge, Silverthorne and Frisco are now working with FEMA to undertake a Physical Map Revision process to make necessary revisions to our communities' flood hazard maps. The revisions being undertaken at this time address only translational errors, i.e., flood hazard area boundaries that were not translated properly to the new maps during the Flood Map Modernization initiative.

The current revision process does not account for recent hydrological changes to the floodplain, such as those caused by the natural migration of water channels, activities of water-dwelling animals such as beavers, human development or survey control inaccuracies in the original adopted maps. It is our hope that FEMA will undertake these types of revisions on a community-wide basis in the near future for Summit County. In the mean time, individual property owners or groups can pursue such map revisions independently.
