To quantify rates of change (erosion or accretion) along coastal and estuarine shorelines in Maryland - the Maryland Geological Survey (MGS) - in conjunction with Towson University's Center for Geographic Information Sciences (CGIS) and the U.S. Geological Survey (USGS) - installed and ran a computer program - the Digital Shoreline Analysis System (DSAS) - using as input a series of digital shoreline vectors dating from 1841-1995. Shorelines were derived from three sources: (1) maps from a Historical Shorelines and Erosion Rates Atlas (Conkwright - 1975) - (2) Coastal Survey maps (topographic or T-sheets) produced by the National Ocean Service (NOS) - a branch of the National Oceanic and Atmospheric Administration (NOAA) - and (3) a digital wetlands delineation based on photo interpretation of digital orthophoto quarter quads. DSAS constructed a 'baseline' landward of and approximately parallel to the shorelines - inserted nodes every 20 m along the baseline - and cast straight-line transects from each node - perpendicular to the baseline - across the shorelines. Based on the time elapsed and the along-transect distance between shoreline pairs - DSAS calculated rates of change for each transect.

The Marsh Protection Potential Index (MPPI) ranks Maryland's 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.

The Maryland coastal zone is comprised of the land - water and subaqueous land between the territorial limits of Maryland in the Chesapeake Bay - Atlantic Coastal Bays and the Atlantic Ocean - as well as the towns - cities and counties that contain and help govern the thousands of miles of Maryland shoreline. The Maryland coastal zone extends from three miles out in the Atlantic Ocean to the inland boundaries of the 16 counties and Baltimore City that border the Atlantic Ocean - Chesapeake Bay and the Potomac River up to the District of Columbia. This area encompasses two-thirds of the State s land area and is home to almost 70% of Maryland's residents.

Each 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's 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). The statements - finding and recommendations are those of the authors and do not necessarily reflect the views of NOAA or the U.S. Department of Commerce.
