point in Coastal Resiliency Assessment Shoreline Points represents a 250 meter segment of the Maryland coast, including Atlantic, Chesapeake Bay and Coastal Bay shorelines. The Natural Capital Project's Coastal Vulnerability model was used to calculate a Shoreline Hazard Index, representing the relative exposure of each segment to storm-induced erosion and flooding. Inputs to the model included 6 physical variables (geomorphology, elevation, sea level rise, wave power, storm surge height and erosion rates) and 5 habitat types (forest, marsh, dune, oyster reef and underwater grass). Two scenarios of the model were run: one scenario incorporating the protective role of all existing coastal habitats and the other scenario simulating the complete loss of habitats. The difference between the two scenarios indicates the potential magnitude of coastal hazard reduction by habitats at each location. Model results were integrated with MD DNR\u2019s Community Flood Risk Areas (March, 2016) in order to highlight areas where hazard reduction by habitats is most likely to benefit at-risk coastal communities. This dataset was produced under award number NA13NOS4190136 from the Office of Ocean and Coastal Resource Management (OCRM), National Oceanic and Atmospheric Administration (NOAA) through the Maryland Department of Natural Resources Chesapeake and Coastal Services (CCS).

coastal marshes by their ability to protect vulnerable communities from coastal hazards. To do so, we identified five key questions to assess each marsh: How much is the marsh able to reduce the impact of coastal hazards? Is the marsh located where coastal hazards are a threat? Is the marsh located where there are people to protect? Is the marsh located adjacent to other protective habitats? Is the marsh likely to survive in the face of rising sea levels? Using data from the Coastal Resiliency Assessment and other sources, we developed metrics to score each marsh on these five questions. Then, the sub-scores were combined to create the Marsh Protection Potential Index overall rating, which ranks the protective ability of over 14,000 marshes statewide. It is important to note that the MPPI ranks marshes relative to other marshes, rather than providing an absolute measure of protective services. The Marsh Protection Potential Index does not attempt to describe the dollar-value of protective services provided by each marsh, nor does it compare marshes to other types of habitat or to other protection infrastructure solutions. In addition, the MPPI does not assess marshes on any of the other characteristics that often inform conservation priorities. Things like biodiversity, ecosystem health, rare species, recreation value, or water quality services are often important to stakeholders, and these are not captured by the MPPI. The MPPI is intended to supplement, not replace, the other ways conservation decision-makers prioritize natural habitats.

danger or damage to life and property as a consequence of inundation and shoreline erosion. These hazards are caused by storms and exacerbated by sea level rise. The Community Flood Risk Areas represent residential areas at risk to coastal flooding where populations may be less equipped to prepare for, respond to, or recover from a coastal hazard event. Risk Areas are ranked from 1 to 5 to indicate relative risk, with 1 indicating very low risk and 5 indicating very high risk. Risk rankings incorporate population density, social parameters (i.e. age, income, language proficiency), and probability of exposure to a flood hazard event in any one given year. 2013 US Census Bureau American Community Survey, 2010 Maryland Department of Planning land use land cover, and effective FEMA floodplain data as of December 2015 were used to identify and rank risk areas.
