PRIMA FACIE EVIDENCE.

(a) In a suit or administrative proceeding brought or defended under this subchapter or whose determination is affected by this subchapter, a showing that the area in question is located in the area from mean low tide to the line of vegetation is prima facie evidence that:

(1) the title of the littoral owner does not include the right to prevent the public from using the area for ingress and egress to the sea; and

(2) there is imposed on the area a common law right or easement in favor of the public for ingress and egress to the sea.

(b) The determination of the location of the line of vegetation by the commissioner as provided by Sections 61.016 and 61.017 constitutes prima facie evidence of the landward boundary of the area subject to the public easement until a court adjudication establishes the line in another place.
