Yanam CRZ

Yanam is bounded on the east and south by the Gauthami-Godavari river, which discharges into the Bay of Bengal 14 km east of the town. The river is tidal up to 45 km from the mouth (per NCSCM CRZ survey data), which puts the entire enclave within the CRZ zone via tidal-water-body classification. The Coringa CVCA mangroves, India's second largest mangrove stretch covering 320 sq km, sits immediately south. CRZ Notification 2019 lists Coringa as a Critical Vulnerable Coastal Area, requiring management with fisher community involvement.

The fact-pack on what each zone permits in Yanam, drawn from CRZ Notification 2019 and the PCZMA SOP.

The No Development Zone (NDZ) along the Gauthami-Godavari river in CRZ-III is 50 metres from HTL or river width, whichever is less. If a seller in Yanam quotes only the 500 m sea CRZ rule, they are reading the wrong section. Yanam has no direct seafront; the entire CRZ here is driven by tidal water body rules under the 2019 notification, and the Coringa CVCA listing strengthens the case for refusing any clearance near the southern boundary.

Yanam region is one municipality covering Yanam municipality six villages plus the town. The town sits on the spot where the Coringa river branches off from the Gauthami-Godavari. Property activity concentrates on the river-front ferry road, the walkway corridor, and the villages bordering the East Godavari district. The Puducherry Coastal Zone Management Authority treats the entire 30 sq km enclave as one CZMP zone, but the river side and the village interiors carry very different CRZ exposure.

The corridors most asked about, mapped against CRZ classification under the 2019 CZMP.

The most misunderstood corridor is the southern village belt facing the Coringa channel. Buyers see open land and assume agricultural plots are unlocked. Coringa is a CVCA listed in CRZ Notification 2019 itself, with mangrove and mudflat stretches classified as CRZ-I A. The Coringa range extends into the Yanam administrative area, and PCZMA treats clearance applications in this belt with explicit CVCA-specific scrutiny.
