An Overview:
My GIS 1 project aimed to create a map illustrating parcels in Harrison and Addison in relation to a 250ft buffer of the coastline. Creating and visualizing these elements lead to an analysis of affected parcels and properties in order to more closely consider the affect of costal shorebird protection areas on landowners. 

Map Summary 1:
My primary map details land parcels adjacent to a 250ft buffer of the coastline. Visually, it is useful to note the geometries of long "spaghetti lots," whose lands are not physically intersecting with the buffer to a degree that would significally devalue their properties or impinge on their building possibilities.

Map Summary 2:
I created a second map to distinguish affected and unaffected portions of the Addison and Harrington coastline. Ultimately, this analysis showed that more than half of the coastline in each town was impacted by costal shorebird habitat. The next step for this map is determining how much of the coast is actually developable (i.e. not marshes, mudflats, etc.) in order to look at percentage of developable coastline affected by shorbird habitat.
