Bengaluru Master Plan 2031

Bengaluru Master Plan 2031 (BMP 2031) is the city’s first comprehensive land‑use and infrastructure blueprint that extends the planning horizon to the year 2031. Drafted jointly by the Bangalore Development Authority (BDA) and the Karnataka Urban Infrastructure Development and Finance Corporation (KUIDFC), the plan was formally approved by the Karnataka cabinet on 30 June 2020, superseding the 1995 Master Plan and the interim 2021 revision. It is distinctive for embedding flood‑resilience, transit‑oriented development, and a 42 percent residential land‑use ceiling within a single, city‑wide framework, thereby attempting to reconcile Bengaluru’s explosive growth with its chronic water‑scarcity and traffic congestion.

Historical Background

The impetus for BMP 2031 can be traced to two successive crises: the 2015 and 2020 monsoon floods that inundated large swathes of the city, and the 2018‑19 traffic gridlock that pushed average commute times beyond 90 minutes. In response, the Karnataka government invoked Section 4 of the Town and Country Planning Act 1961 to commission a fresh master plan, appointing a steering committee chaired by the Chief Minister’s Principal Secretary for Urban Development. The committee incorporated inputs from the Bruhat Bengaluru Mahanagara Palike (BBMP), the Karnataka State Pollution Control Board, and the Indian Institute of Science’s Centre for Urban and Regional Development, ensuring that scientific flood‑modelling and transport‑demand forecasts underpinned the final document.

Key Provisions

BMP 2031 allocates the city’s 741 sq km area as follows: 42 percent residential, 30 percent commercial, 12 percent industrial, 5 percent institutional, 5 percent open‑space, and the remaining 6 percent for mixed‑use and other purposes. The plan earmarks 1,000 hectares for new or restored lakes, wetlands, and storm‑water reservoirs, aiming to raise the city’s per‑capita water storage capacity from 0.5 litres to 1.2 litres. Transport provisions include 400 km of dedicated cycle tracks, 300 km of Bus Rapid Transit (BRT) corridors, and the reservation of 15 percent of all new road right‑of‑way for future metro extensions under the Namma Metro Phase‑III and Phase‑IV projects. Housing policy mandates that every new residential plot reserve at least 0.5 percent of its area for percolation pits, while the “Green‑Cover” clause obliges developers to plant trees at a density of 15 trees per 100 sq m, targeting a city‑wide canopy cover of 30 percent by 2031.

Implementation Mechanisms

The BDA is charged with preparing detailed development plans (DDPs) for each of the 12 planning zones, a task coordinated through the Metropolitan Planning Committee (MPC) established under the 1961 Act. The MPC meets quarterly, reviewing progress against a ten‑year phased schedule that prioritises the Peripheral Ring Road (PRR), the East‑West Corridor, and the redevelopment of the KR Puram‑Whitefield corridor. Funding is sourced from a blend of state‑allocated capital, the Smart Cities Mission grant of ₹1,200 crore, and the National Urban Housing and Infrastructure Mission (NUHIM) tranche of ₹2,500 crore earmarked for affordable housing and water‑supply upgrades. Land‑acquisition for the PRR and the proposed satellite townships at Devanahalli, Yelahanka, and Hoskote is being executed under the Karnataka Land Acquisition Act 2014, with compensation packages calibrated to the market‑value index published by the Department of Revenue.

Significance and Challenges

By integrating flood‑mitigation infrastructure with land‑use zoning, BMP 2031 directly addresses the hydrological failures that caused the 2020 deluge, which claimed 123 lives and displaced 1.2 million residents. The plan’s emphasis on mixed‑use, high‑density development around metro stations mirrors the “Transit‑Oriented Development” (TOD) model championed in cities such as Copenhagen and Singapore, promising to curb the current vehicle‑kilometre‑travel (VKT) growth rate of 7 percent per annum. Critics, however, point to persistent bottlenecks in land‑acquisition, the risk of speculative real‑estate practices, and the need for stronger inter‑agency data sharing—issues that have delayed the rollout of the East‑West BRT by 18 months as of 2023. Environmental NGOs also caution that the 5 percent open‑space allocation may be insufficient to offset the projected loss of 12 sq km of greenfield land due to ongoing urban sprawl.

Current Status

As of October 2023, the BDA has notified revised zoning maps for the North‑East
