Bellandur Lake Buffer Road Plan Sparks Legal Storm: Is GBA Chief Ignoring NGT & Tank Laws?

The issue assumes greater significance given Bellandur Lake’s status as one of Bengaluru’s most environmentally sensitive and legally scrutinised water bodies, repeatedly flagged by courts for protection and restoration.

WHAT THE LAW CLEARLY STATES

Karnataka Tank Conservation & Development Authority Act

Under Chapter III – Protection of Tanks, the law categorically prohibits:

• Construction of roads, bridges, or structures within tank areas or tank bunds without Government permission
• Any activity within 30 metres of the outer boundary of a tank
• Obstruction of natural inflow or outflow of water
• Any act detrimental directly or indirectly to tanks

Section 12(6) explicitly states:

“No roads, bridges or similar structures shall be constructed within the tank area including the tank bund without permission of the Government.”

Violations empower authorities to seize machinery, halt works, and initiate criminal proceedings.

BUFFER ZONE RULES UNDER RMP 2015 & PLANNING LAW

As per the Revised Master Plan (RMP) 2015, Bellandur Lake is categorised under Valley/Drain and Park & Open Space (P) zoning, which mandates:

• A mandatory 30-metre ‘No Development Zone’ around lakes
• Only non-obstructive uses like pathways or drains are conditionally allowed
• No fresh development permissions in valley zones
• Roads allowed only if they do not obstruct natural water flow and only with explicit statutory approvals

Any deviation requires clearances under planning law, environmental law, and judicial compliance, not merely an administrative inspection or survey.

NGT & SUPREME COURT: SETTLED LEGAL POSITION

In the landmark Forward Foundation cases (2016), the National Green Tribunal ruled that:

• Lake buffer zones are ecologically sensitive no-construction zones
• Infrastructure convenience cannot override environmental protection
• Government agencies act as trustees of lakes, not developers

Subsequently, in Mantri Techzone Pvt Ltd vs Forward Foundation (2019), the Supreme Court held that buffer zones must be restored as per the zonal plan/master plan, recognising:

• 30-metre buffer around lakes
• 50m / 25m / 15m buffers from primary, secondary, and tertiary rajakaluves

The legal position today is clear: lake buffers are not discretionary spaces.

CORE CONCERNS RAISED

Despite this settled legal framework, the GBA press communication does not mention:

• Any NGT or Supreme Court order permitting road construction
• Environmental clearance or Wetlands Act compliance
• Government approval overriding tank protection laws
• Legal vetting prior to ordering the survey

Sources indicate that engineering officials attempted to flag buffer-zone constraints during the inspection, yet the survey directive was still issued—raising questions about procedural overreach.

“SURVEY FIRST, LAW LATER?”

Environmental experts warn that ordering surveys without resolving legal prohibitions sets a dangerous precedent, especially in lake ecosystems.

“In buffer zones, even a survey becomes the first step towards legitimising illegality,” a senior environmental lawyer noted.

Bellandur Lake is already under stress from flooding, sewage inflow, encroachments, and prior violations. Any dilution of buffer protections could have irreversible ecological consequences.

GOVERNANCE UNDER SCRUTINY

As the top civic administrator overseeing five city corporations, the GBA Chief Commissioner is expected to ensure that law precedes infrastructure ambition—particularly in ecologically sensitive zones.

Failure to do so exposes the government to:
• Legal challenges
• Tribunal intervention
• Public opposition
• Accountability for environmental damage

WHAT LIES AHEAD

Unless backed by:
• Explicit NGT or Supreme Court relaxation
• Statutory planning approvals
• Environmental and wetland clearances

Any attempt to construct roads inside Bellandur Lake’s buffer zone is likely to be legally stalled.

BOTTOM LINE

Traffic congestion is a governance challenge—but lake protection laws are not optional.
Any road inside Bellandur Lake’s buffer zone must pass legal, environmental, and judicial tests, not just administrative inspections.

For Bengaluru, the real test is not how fast projects are announced—but how lawfully they are executed.
