The Bengaluru Metropolitan Region Development Authority (BMRDA) was established on February 1, 1986, to oversee the planned development of the Bengaluru Metropolitan Region, which includes Bengaluru Urban, Bengaluru Rural, and Ramanagara districts, covering approximately 8005 sq.kms. The authority is responsible for creating structure plans, coordinating town planning schemes, and promoting sustainable development through spatial planning while addressing population growth projected to reach 18 million by 2031. The revised structure plan for 2031 aims to manage urbanization, enhance regional accessibility, and support decentralized governance while preserving ecological balance.
