The storm surge zones data used in this application were generated using the Sea - Lake - and Overland Surges from Hurricanes (SLOSH) model. SLOSH is a computerized model run by the National Weather Service to estimate storm surge heights resulting from historical - hypothetical - or predicted hurricanes. The model creates its estimates by assessing the pressure - size - forward speed - track - and wind data from a storm. Graphical output from the model displays color-coded storm surge heights for a particular area. The calculations are applied to a specific locale's shoreline - incorporating the unique bay and river configurations - water depths - bridges - roads - and other physical features. This file is generated as part of the Hazards Analysis within the Hurricane Evacuation Study for the Maryland Western Shore.

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.

This data layer is a compilation of the MUPOLYGON feature class - muaggatt table and component table of the Gridded Soil Survey Geographic (gSSURGO) Database for Maryland. United States Department of Agriculture - Natural Resources Conservation Service. Under the direction of the Watershed Resources Registry (WRR) Technical Advisory Committee (TAC) this data has been altered from its original state. A reclassification of the hydric classification field was performed which classifies all soil map units consisting of less that 40% total hydric soils as not hydric - all soil map units from 41% - 79% as partially hydric and all soil map units 80% and greater as hydric. This reclassification was performed to provide a more refined input for modeling purposes. A full version of this database is available at: http://datagateway.nrcs.usda.gov/.

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.

Census Blocks are statistical areas bounded on all sides by visible features - such as streets - roads - streams - and railroad tracks - and/or by nonvisible boundaries such as city - town - township - and county limits - and short line-of-sight extensions of streets and roads. Census blocks are relatively small in area; for example - a block in a city bounded by streets. However - census blocks in remote areas are often large and irregular and may even be many square miles in area. A common misunderstanding is that data users think census blocks are used geographically to build all other census geographic areas - rather all other census geographic areas are updated and then used as the primary constraints - along with roads and water features - to delineate the tabulation blocks. As a result - all 2010 Census blocks nest within every other 2010 Census geographic area - so that Census Bureau statistical data can be tabulated at the block level and aggregated up to the appropriate geographic areas. Blocks are the smallest geographic areas for which the Census Bureau publishes data from the decennial census.
