The Future Coast viewer will provide you with projections of the potential impact of sea-level rise on inundation and coastal flooding at varying geographic scales. The projections of future sea level are based on best available scientific information, but have large uncertainties and are subject to change as the state of the science evolves. The presented map coverages of the flood and inundation scenarios reflect Maryland Climate Change Commission sea level projections analyzed against current topographic and building asset data using best practices. Reported probabilities of potential flooding and property damage are relative to today's condition and reflect exposure as determined from analysis of the Maryland Climate Change Commission scenarios against the base data. The values do not reflect the likelihood of changes in climate and or sea level.

George Mason University and its officers, employees, agents, contractors, and subcontractors cannot guarantee the accuracy or reliability of the information provided in the viewer. Users rely on information contained in the Future Coast viewer at their own risk, and any conclusions or decisions based on the use of these tools are the responsibility of the user.

The map should be used only as a screening-level tool to consider potential policy responses to sea-level rise and coastal flooding. The assessments herein were derived from remotely sensed data and were not verified by site visits. This work shall not be used to assess exposure to coastal flood hazards, insurance requirements, ground elevation, or property attributes. Users should refer to the Federal Emergency Management Agency Flood Insurance Rate Maps for flood exposure and regulatory information.

The data and maps in this tool are provided "as is," without warranty to their performance, merchantable state, or fitness for any particular purpose. The entire risk associated with the results and performance of these data is assumed by the user. This tool should be used strictly as a tool for public consideration of potential local government policies and not for navigation, permitting, or any other legal or regulatory purposes.
