A GIS based model of rolling easement policies in Pinellas County and Sarasota County, Florida

Florida is the fourth most vulnerable coastal state in the USA to sea level rise (SLR). Studies predict that a 1.20 m rise translates into the displacement of almost five million people and destroys about 2.6 million homes. The only solution to reducing the vulnerability of Florida’s coastline is the creation and implementation of coastal policies, including a reduction in armoring and the adoption of policies such as rolling easements. This paper advances a SLR inundation computer model that estimates the costs of applying rolling easement policy through three outcomes: property value loss, property area loss and conservation easement payments to home owners. The GIS computer model is modular which allows new policy components, datasets, or ArcGIS tools to easily be added to the model. The results show that property land inundation and real property losses are primarily linear while rolling easement compensation payments are substantial during the first three scenarios then are largely stable for the remaining SLR steps.

Castles—and Roads—in the Sand: Do All Roads Lead to a “Taking”?

The law has been slow to acknowledge the unprecedented nature of sea-level rise. Unless and until the law adapts, past case law on coastal hazards exacerbated by sea-level rise provides the best guidance. This Article critically examines a Florida case that addressed local government liability for coastal erosion damage to a road and dramatically altered Florida law in two key respects. First, the case altered and expanded the concept of “maintenance” of road infrastructure by a local government as the baseline duty that must be met to avoid potential legal liability. Second, the case introduced into Florida law the controversial idea that “inaction” may support a Fifth Amendment takings claim. The Article traces how other courts have unwittingly or carelessly introduced “inaction” into their takings jurisprudence, and evaluates whether and when inaction should be sufficient basis for a takings claim. It draws out serious policy implications of the case in light of sea-level rise, and makes recommendations to address fallout from the case.
