History of Civic Administration[edit]

Bidhannagar was originally developed and built under the direct administration of the Irrigation and Waterways Department of the Government of West Bengal. Originally, it came under the Public Works (Metropolitan Development) Department. It then came under the wings of Metropolitan Development Department which was renamed the Urban Development Department in 1991. In 1989, a Notified Area Authority had been set up to administer the area.


Ultimately in 1995, Bidhannagar got its own elected body called Bidhannagar Municipality consisting of 23 wards (later increased to 25 wards). All the plots of land in Bidhanannagar are leasehold plots and the Urban Development Department (the Lessor) directly manages the land matters. The proposal for merger of Bidhannagar corporation with the Kolkata Municipal Corporation has been periodically mooted since 2011.[4] Air Port, Rajarhat, Gopalpur, Baguiati, Kestopur, Salt Lake, Lake Town are already under the jurisdiction of the Bidhannagar Police Commissionerate. On 18 June 2015 Bidhannagar Municipal Corporation (BMC) was constituted by merging the existing municipal areas of Bidhannagar Municipality and Rajarhat Gopalpur Municipality and the panchayat area of Mahishbathan II Gram Panchayat.[5]


The Bidhannagar Police Commissionerate is responsible for law enforcement in the city.
