Chennai: As many as 22 beach-facing residential buildings in Muttukadu on East Coast Road (ECR) face the threat of demolition, with the Chengalpattu district administration identifying them as violators of Coastal Regulation Zone (CRZ) rules. The identified buildings—some completed, others still under construction—are located within the No Development Zone (NDZ) of CRZ III, where permanent structures are banned within 200 metres of the High Tide Line.At least six of these were found to be under construction even during the inspection, indicating ongoing activity despite regulatory restrictions. Others are upscale, completed buildings, with some even having two floors, built along the fragile coastal stretch at Muttukadu.These findings were part of an Action Taken Report submitted by Chengalpattu Collector S Arunraj to the National Green Tribunal (NGT), which took suo motu cognisance of the matter. The collector’s team, comprising revenue and environmental officials, carried out GPS-tagged inspections and submitted photographs and ownership details to the Tamil Nadu State Coastal Zone Management Authority (TNSCZMA) to initiate action.The case, heard on Thursday, saw the tribunal’s expert member Satyagopal Korlapati ask pointed questions on why no demolition was initiated so far, given that violations were already acknowledged by the administration. The NGT also noted that the District Collector, as chairman of the district coastal zone management authority (DCZMA), was expected to act decisively against such illegal developments.In response, the state coastal zone management authority (SCZMA) informed the bench that it forwarded the list of violators to the Union Ministry of Environment, Forest and Climate Change, seeking clarification on whether it had the authority to directly carry out demolitions. The NGT is now expected to decide on whether demolition can proceed without waiting for further directions from the Centre. The matter is likely to be taken up in the coming weeks.
