Construction activities around Pallikaranai marshland can be regulated, not banned: TNSWA tells Madras High Court
It also submits a proposed interim ‘Zone of Influence’ prepared by the National Centre for Sustainable Coastal Management
On August 20, 2026, the Tamil Nadu State Wetlands Authority (TNSWA) informed the Madras High Court that construction regulations could apply rather than a complete ban in the 'zone of influence' surrounding Chennai's Pallikaranai marshland. The National Centre for Sustainable Coastal Management (NCSCM) proposed an interim ZoI, with widths ranging from zero to 100 meters depending on specific site characteristics.
The AAG informed the court that the NCSCM's report recommended a site-specific approach due to the marshland's urban surroundings, diffused drainage, and gentle terrain. The court granted two weeks for counsel to review the report before further submission on September 7, 2026.
