Facilities such as ramps, lifts, or mobility paths for physically handicapped persons are also 596 allowed for achieving access to shore areas, if they are consistent with the dimensional and 597 performance standards of items a-e above and the requirements of Minnesota Rules, Chapter 598 1341. 599 3.
