Karaikal CRZ
State Coastal Zone Management Authority
Overview
The Karaikal CRZ layer plots the Coastal Regulation Zone footprint along Karaikal's 20 km coastline, the second longest in the U.T. of Puducherry after Pondicherry's 24 km. It mirrors the revised Coastal Zone Management Plan prepared by NCSCM (National Centre for Sustainable Coastal Management) under CRZ Notification 2019 (G.S.R. 37(E)), with the Karaikal region public hearing held on 7 November 2024. The Puducherry Coastal Zone Management Authority (PCZMA) is the regulatory body. This page shows what falls inside CRZ-I, CRZ-II, CRZ-III A, CRZ-III B, and CRZ-IV across Karaikal town, the Arasalar estuary, and the fishing villages. As of May 2026, the Puducherry CZMP under CRZ Notification 2019 has not received confirmed MoEFCC approval despite the November 2024 public hearing. CRZ 2011 rules continue to govern in the interim. Buyers should verify with PCZMA which notification is operative for their specific survey number.
Regulatory Red Flags Inside the No Development Zone
Karaikal sits on the Coromandel Coast, surrounded on three sides by the Cauvery delta districts of Tamil Nadu. Every coastal parcel here gets read against two CZMPs: the older 2011 plan still on PCZMA's map page, and the 2019 plan that went through public hearing in November 2024. Buyers routinely confuse the two, and brokers quote whichever is more favourable.

If a seller cannot show your survey number against the approved CZMP map on PCZMA's portal, that plot's CRZ status is unverified. The split between CRZ-III A and CRZ-III B in Karaikal turns on Census 2011 density, and the No Development Zone (NDZ) flips between 50 m and 200 m depending on which side of that threshold the village falls.
Growth Corridors Around Karaikal Beach, Arasalar Estuary and the Port
Karaikal has 12 fishing hamlets and a coastline anchored at three nodes: Karaikal Beach near the river mouth, the Arasalar river estuary north of it, and the deep-water Karaikal port and fishing harbour complex south of the Arasalar mouth. Each carries different CRZ exposure.
The corridors most asked about, mapped against CRZ classification under the 2019 CZMP.
Karaikal Town core

Known Risk
Estuary buffer; no private build
Karaikal port / Sanmar terminal
Zone (Karaikal CZMP 2019)

Industrial, deep-water harbour
Known Risk
Port operational area classified CRZ-II; new construction requires PCZMA clearance beyond existing authorised port limits.

Connectivity to Chennai-Thoothukudi
Known Risk
Rs 60 crore NH-32 strengthening announced October 2025 — improves connectivity but does not change CRZ classification for fringe parcels. Fringe parcels misquoted as "outside CRZ".

The most misunderstood corridor is the Arasalar estuary stretch. Buyers see the boating club and assume the area is open for resort development. Mangroves and the fish breeding area mark this as CRZ-I A and CRZ-IV B, where private construction is essentially blocked. The "river-facing" plots advertised here usually sit inside the 100 m tidal-water-body buffer or on the 50 m NDZ along the creek, both of which freeze build rights.
