Transition Zone Buffers, 2019

Oct 4, 2018 (Last modified Mar 15, 2019)


- This dataset is the key deliverable for this effort. Potential transition zone was defined by several factors. Two separate 500m buffers were created. The first was around all existing estuarine wetlands. The second buffer was created around a Lidar-derived contour approximately equal to the elevation of local mean higher high water (MHHW) (taken for each county from tide gauges). From these two buffers, the following areas were erased: beaches, oceans, deveoped land, existing estuarine wetlands, and areas of high elevation and slope. The remaining portions of the first buffer (500m from estuarine wetlands) were defined as 'Present Transition Zone'. The remaining portions of the second buffer (500m from MHHW) that did not intersect with the first buffer were defined as 'Future Potential Transition Zone'.
