(a) At the request of the commissioners court, a lake planning commission shall, or on its own initiative a commission may, conduct studies of the lake area over which it has jurisdiction and prepare reports to advise the commissioners court about the boundaries of the original zoned districts, other regulations for the lake area, and changes to those districts or regulations.
(b) Before the commission may prepare a report, it must hold a public hearing at which members of the public may present testimony about any subject to be included in the commission’s report. The commission shall give notice of the hearing as required by the commissioners court.

(c) If a report will advise the commissioners court about proposed action regarding the zoning classification of a parcel of land, the commission shall send written notice to each landowner, as listed on the county tax rolls, whose land is directly affected by the proposed action or whose land is located within 200 feet of land directly affected. The notice must inform the landowner of the time and place of the public hearing at which the landowner may present testimony to the commission about the proposed action and must be deposited in the United States mail before the 10th day before the date of the hearing.
