Tex. Natural Resources Code § 63.054

(a) The commissioners court or governing body of the municipality shall evaluate the permit application, and if the commissioners court or governing body of the municipality finds as a fact after full investigation that the particular conduct proposed will not materially weaken the dune or materially damage vegetation on the dune or reduce its effectiveness as a means of protection from the effects of high wind and water, it may grant the permit.

(b) In determining whether or not to grant the permit, the commissioners court or governing body of the municipality shall consider the height, width, and slope of the dune, any significant environmental features of the dune, the feasibility and desirability of restoration of vegetation, and cumulative impacts and shall consider requirements for protection of critical dune areas.

(c) Each county or municipality administering this chapter shall establish procedures and requirements governing the review and approval of dune permits, and these procedures and requirements shall be submitted to the commissioner for certification to determine whether the procedures and requirements are in compliance with rules and policies adopted under Section 63.121. The commissioner shall act on a county or municipality's proposed dune protection plan not later than the 90th day after the date the plan is submitted by approving the plan or denying certification. If certification is denied, the commissioner shall return the proposed plan to the originating local government with a statement of specific objections and the reasons for denial, along with suggested modifications. On receipt, the county or municipality shall revise and resubmit the plan. The commissioner must certify a county or municipality's procedures and requirements under this section in accordance with rules adopted under Section 63.121.
