For flood protection and regional facility planning projects, applicants must notify all cities, counties, non-profit water supply corporations, regional planning agencies, regional water planning groups, and all districts and authorities created under the Texas Constitution, Article III, Chapter 52, or Article XVI, Chapter 59, in the planning area by certified mail that an application for planning assistance is being filed with the board. The notice shall include the name and address of the applicant and the name of the applicant's manager or official representative; and brief description of the planning area; the purposes of the planning project; the board's name, address, and the name of a contact person with the board; a statement that any comments must be filed with the executive administrator and the applicant within 30 days of the date on which the notice is mailed. Prior to action by the board, the applicant must provide one copy of the notice sent to affected political subdivisions, a list of the political subdivisions to which notice was sent, and the date on which the notice was sent. The board may not act on such application before the end of the 30-day notice period unless all political subdivisions to which notice is required to be sent agree in writing to waive the notice period.
