Odo-Otin North and Odo-Otin South LCDAs
Odo-Otin North Local Council Development Area and Odo-Otin South Local Council Development Area (LCDAs) were created out of Odo Otin area council for administrative convenience, better development planning and to bring government closer to the grassroot.[2] The LCDA is created by the Government of Osun State and is responsible for the funding of the council. The LCDA is headed by a chairman, vice chairman and other executive and legislative branches similar to the federally recognized local councils. The current chairmen for the LCDAs are Adekeye Adebayo Iyiola (Odo-Otin North) and Prince Akinloye Aliyu Oluwole (Odo-Otin South).[3][4]
