If the board of supervisors of any county at any time finds that twenty-five percent or more of the total area of any established drainage district is located within the corporate limits of any city, that the district’s drains are wholly or partially constructed of sewer tile, and that the district’s drain or drains are needed or being used by the city for storm sewer or drainage purposes, the board may by resolution transfer to the city control of the entire drainage district, including the portion outside the corporate limits of the city.
