The district or any new district created by the division of the district may not annex the property of a landowner before obtaining written consent from the landowner. The annexation of the property must be completed by the district not later than one year after the district's receipt of the landowner's written consent. A landowner may revoke the landowner's consent to annexation before annexation by notifying the district in writing that the consent is revoked. A landowner's petition for annexation that meets the requirements of Chapter 49 or 54, Water Code, shall be considered as the landowner's written consent for the purposes of this section.
