Mahe CRZ
State Coastal Zone Management Authority
Overview
The Mahe CRZ layer plots the Coastal Regulation Zone footprint across the smallest district in India by land area, just 8.69 sq km, with only 1 km of seafront on the Arabian Sea. It mirrors the Coastal Zone Management Plan prepared for Mahe by the Puducherry Coastal Zone Management Authority (PCZMA) under CRZ Notification 2019 (G.S.R. 37(E)). Mahe is part of Puducherry U.T. but surrounded on three sides by Kannur district and on one side by Kozhikode district of Kerala. This page shows what falls inside CRZ-I, II, III A, III B, and IV across Mahe town and the four Naluthara villages.
Regulatory Red Flags Around the Mayyazhi River Estuary
Mahe is a regulatory anomaly. The land is governed by Puducherry under CRZ Notification 2019 and PCZMA, but the Mayyazhi river estuary that defines its northern boundary flows from Wayanad through Kerala before reaching the sea at Mahe. The CZMP map for Puducherry-Mahe is separate from the Kerala CZMP for Kannur and Kozhikode, but the river course is documented in both, and lawyers routinely confuse which authority's clearance applies to a given parcel.

Given Mahe's tiny 9 sq km footprint, almost every parcel sits within either the 500 m sea CRZ or the 50 m No Development Zone (NDZ) along the tidal river. If a seller cannot show the survey number against PCZMA's approved Mahe CZMP map, that plot's CRZ status is unverified, and a Kannur or Kozhikode broker who quotes the Kerala CZMP is reading the wrong document.
Growth Corridors Across Mahe Town and the Naluthara Villages
Mahe is administratively one municipality with two parts: Mahe town and Naluthara villages. Naluthara comprises Pandakkal, Pallur, Chalakara, and Chembra. The seafront sits on the Mahe town side. The river bank stretches across both. The Puducherry Coastal Zone Management Authority treats the entire enclave as one CZMP zone, but classification within the 8.69 sq km area varies sharply by village density and proximity to the Mayyazhi river.
The corridors most asked about, mapped against CRZ classification under the 2019 CZMP.

The most misunderstood corridor is the river-bank stretch. Buyers see the Mayyazhi promenade and assume the entire river frontage is CRZ-II urban. CRZ Notification 2019 places a 50 m NDZ along tidal water bodies in CRZ-III, plus the river mouth and adjacent mangrove patches as CRZ-I A. River-facing parcels in Pandakkal or Pallur usually sit inside this band, regardless of the panchayat classification.
