Any district which has been included in a consolidated district may withdraw from the consolidated district and be reconstituted as a separate district by filing with the board of directors of the consolidated district a petition for withdrawal which is signed by the owners of not less than 51 percent by area of citrus land in the district. The board of directors of the consolidated district shall send the original petition to the board of supervisors of the county in which the withdrawing district is located, and a copy of the petition to the board of supervisors of each of the other counties in which is located any part of the consolidated district. Upon receipt of a petition for withdrawal, the board of supervisors of the county in which the withdrawing district is located shall fix a time and place for hearing the petition. Notice shall be given and the hearing conducted in the same manner and with the same effect as prescribed for the formation of a district under Chapter 2 (commencing with Section 8451). Upon withdrawal of a district, all moneys collected from the district for the use of the consolidated district, and all property purchased with these moneys, shall remain the property of the consolidated district. All moneys collected from a district after it withdraws from a consolidated district shall be held for the use of the district.
