As population expands and homes, businesses, and infrastructure are sited over all types of Vermont landforms, it is inevitable there will be conflicts between development and natural hazards such as landslides, erosion from flood events,and bank failure on lakes. Catastrophic bank failure can occur, threatening or destroying buildings and infrastructure. Erosion damage from flood events can be considerably more costly than inundation damage to the built environment. Riverine erosion may or may not occur in the 100 year floodplain. As a result of the these land use conflicts, public and private investment is lost to catastrophic events. Protection of public health and safety and a reduction in financial losses is a priority. Hazard maps are a primary tool for mitigation. A hazard map identifies areas of higher risk. With these maps, towns can clearly identify areas where land use oversight can be employed.

The outcome will be the protection of public health and safety and the means to preserve public emergency funds when a clear warning can prevent unwise construction and loss of the built environment.
