Tex. Local Government Code § 321.047

(a) On or before July 1 of each year, the board shall prepare and file with the county judge a complete financial statement showing the financial status of the board and the board's properties, funds, and indebtedness.

(b) The financial statement must be in two parts or prepared to show separately all information concerning:

(1) revenue bonds, the pledged income from facilities, and expenditures of that revenue; and

(2) money appropriated to the board by the commissioners court and realized from taxation and money realized from the sale of tax-supported bonds previously issued by the commissioners court.

(c) At the same time the financial statement is filed, the board shall file with the county judge a proposed budget of its needs for the next calendar year. To the extent that the board is able to finance its operations and to maintain its property from the revenues of facilities the income of which is pledged to the revenue bonds, no approval or authorization of the commissioners court is necessary. However, the budget may involve only anticipated supplemental expenditures.

(d) The county judge shall incorporate the requested budget in the county budget to be prepared each year. As part of the county's tentative budget, the items certified by the board are subject to the procedure for county budget prescribed by Chapter 111.

(e) The board shall operate the parks under its control the revenues of which are pledged to the payment of bonds in a manner that will produce gross revenues sufficient to pay the operation and maintenance expenses of the facilities without seeking from the commissioners court the appropriation of additional money for those expenses.
