Fla. Stat. § 157.11
Lateral drains may be established in like manner as main ditches, drains or canals. Such lateral ditches, drains or canals may be made a part of the original plat and survey of such main ditch, drain or canal, and may be in the original petition therefor, or may be established in like manner under the provisions of this chapter, at any time after the completion of such main ditch, drain or canal. Any drain or lateral that has been constructed, or which may hereafter be constructed, under the provisions of this or any prior act, shall be and remain under the exclusive control and direction of the board of county commissioners, and no drain shall be connected therewith or cut into the same without the consent of the board of county commissioners first obtained in writing, stating how such connection shall be made, and the connection shall then be made in such manner as the said board shall direct; and any person failing to observe the direction of the board in making such connection shall be guilty of a misdemeanor of the second degree, punishable as provided in s. 775.082 or s. 775.083. The said board of county commissioners may enlarge or extend any drain and drainage district, or deepen or widen any drain, and assess the property benefited and raise the money and pay the cost thereof under the same conditions and procedure provided herein for the establishment and construction of drains; provided, that a drain may be deepened and widened upon the petition of one-fourth of the owners of property, or the owners of one-fourth of the property originally assessed for the construction thereof. Any mistake, oversight, miscalculation or error in any proceedings had under this chapter may be corrected, and shall thereafter be deemed and held as valid and binding as if the same had not occurred.
