What are baselines and setback lines?
The baseline is established at the location of the crest of the primary oceanfront sand dune. In the areas that lack a primary dune, the line is established where the crest of the primary ocean front sand dune for that zone would have been if the shoreline had not been altered by erosion control devices, groins or other man-made alterations. The setback line is the line landward of the baseline that is established at a distance which is forty time the average annual erosion rate as determined by historical and other scientific means and adopted by the OCRM.
