Description:

The impact of sea level rise on coastal properties depends critically on the human response to the threat, which in turn depends on several factors, including the immediacy of the risk, the magnitude of property value at risk, options for adapting to the threat and the cost of those options, and in some cases, land-use or regulatory restrictions that apply to the property. This model estimates the response to and economic impacts of sea level rise on coastal properties using a spatially comprehensive Geographic Information System (GIS)-based modeling approach that considers each of the aforementioned factors. The model can be used for a number of purposes, including the development of: 1) national-level estimates of the benefits of reducing sea level rise through the mitigation of greenhouse gas emissions; and 2) local-level results assessing management actions that could facilitate adaptation to sea-level rise risks.

Model Inputs :Elevation data, planning and land use data, property data, shoreline characterization data. A number of other parameters (e.g., cost of different shoreline protection strategies, sea level rise scenarios, timeframe, etc) can be manipulated, however default values are provided. The model is distinctive for its comprehensive geographic coverage, rapid run-time, and the flexibility of inputs.

Model Outputs :Total area and value of parcels at risk, area and value of parcels abandoned, costs of different protection strategies (beach nourishment, elevation of land, and construction of armoring structures), and total costs. The model is also capable of producing cumulative discounted damage costs over the full modeling period and maps displaying response results by grid cell.
