Living near the coast? What you must know about Coastal Regulation Zone guidelines

CRZ rules are meant to guide coastal development and protect marine ecosystems. This video explains what activities are allowed along the coast.

Waking up to the sound of waves crashing against the shore and enjoying a panoramic view of the sea from your high-rise balcony. It’s the kind of lifestyle promoted by real estate brochures, luring home buyers with properties steps away from the beach. But what about the impact of indiscriminate development along the coastline?

Coastal areas are delicate ecosystems that bear the brunt of unchecked urban expansion. This development often comes at the cost of mangroves, sand dunes and delicate marine habitats. Recognising this looming threat, the Government of India introduced the Coastal Regulation Zone (CRZ) guidelines. These are specifically important for big, coastal cities like Mumbai and Chennai.

The CRZ notification is a set of rules meant to protect coastal ecosystems. According to the annual report for 2023-24 released by the Union Ministry of Home Affairs, the length of India’s coastline is 11,098.8 km. Under the Environment (Protection) Act, 1986, the first CRZ notification was issued in 1991 to regulate the activities in and around the coast of India. The notification has undergone several amendments since then.

The chimneys of the NTECL Vallur Thermal Power Station, billowing smoke, loom over Kuruvimedu in Ponneri, Thiruvallur near Chennai. Wedged between the plant and its sprawling 300-acre ash pond, the hamlet lies under a blanket of kari (coal) and sambal (ash), coating its narrow streets, colourful homes, and trees. Kuruvimedu is hard to find on Google maps, just as its namesake bird. The main road leading to this place is flanked by factories and industrial complexes, its surface riddled with potholes that make every journey dangerous for motorists.  Home to mangroves, networks of canals, and fields, Kuruvimedu once buzzed with…

Pallikaranai’s 1-km buffer zone sparks debate on housing rights, encroachment and ecology

On World Wetland Day, Chennai's Pallikaranai marsh shows how decades of state‑sanctioned encroachment leave residents and ecology at risk.

Across Pallikaranai marshland, migratory birds can be spotted, searching for forage and water. Yet the wetland they depend on has steadily depleted. As Chennai has grown in an amoeba-like manner, ebbing with the promise of ‘development,’ the marsh has borne the brunt. In the 1990s, the marsh covered 2,450 hectares, nearly 70% of its original size. Today, barely 500 hectares remain. In recent years, the marshland has often entered public discourse. In September 2025, Chennai Metropolitan Development Authority (CMDA), acting on an order from the southern bench of the National Green Tribunal, halted planning permission for development within the Pallikaranai…
