Setback changes: One of the most obvious tools is to change regulatory setback requirements within risk zones. This might entail increasing the shoreline setback distance for structures to allow for shoreward migration in these at risk areas. For example, shoreline residential areas currently have a required 50-foot minimum setback from the ordinary high water mark (OHWM) for non-water dependent structures. This setback could be increased for any new structures within a risk zone as necessary to reduce or remove the risk. This would do little, however, to promote shoreward migration where structures currently exist.
