Karnataka CRZ
Karnataka State Coastal Zone Management Authority
Overview
The Karnataka CRZ layer plots the Coastal Regulation Zone footprint along the state's 320 km coastline on the Arabian Sea. It mirrors the Coastal Zone Management Plan approved by MoEFCC at the National Coastal Zone Management Authority's 45th meeting on 1 September 2022, prepared under CRZ Notification 2019 (G.S.R. 37(E)) for three coastal districts: Uttara Kannada, Udupi, and Dakshina Kannada. The Karnataka State Coastal Zone Management Authority (KSCZMA) is the regulatory body. Karnataka is one of only four approved states under CRZ 2019, alongside Odisha, Maharashtra, and Kerala (Kerala's 10 districts approved October 2024). This page shows what falls inside CRZ-I, II, III A, III B, and IV across the Karnataka coast.
Regulatory Red Flags Around Karwar, Coondapur and the Sewage-Polluted Stretch
Karnataka has two of India's listed Critical Vulnerable Coastal Areas: Karwar and Coondapur CVCA (Critical Vulnerable Coastal Area), both named explicitly in CRZ Notification 2019 alongside Sundarban, Vembanad, and Gulf of Mannar. The CAG (Comptroller and Auditor General) performance audit also documented untreated sewage discharge from 11 of 12 coastal urban local bodies in Karnataka directly into the sea. Only Mangalore City Corporation operates a 100% sewage network with four treatment plants.

The Karnataka-specific trap is the assumption that local panchayat or town panchayat approvals override CRZ. The CAG audit flagged two specific Karnataka violations: four additional berths at New Mangalore Port and a petroleum product storage terminal at Karwar. If a parcel sits along the Tulu-Konkan stretch in Ullal, Mulki, Saligrama, Honnavar, Kumta, or Ankola, where eight cities still depend on septic tanks and soak-pits, expect tighter enforcement once sewage compliance is forced through KSCZMA review.
Growth Corridors From Mangalore to Karwar Across the Tulu-Konkan Belt
Karnataka's coast splits into three personalities. The Mangalore Udupi Karwar coast stretches across Dakshina Kannada urban (CRZ-II dominated), Udupi semi-urban with mixed CRZ-II and CRZ-III, and Uttara Kannada largely rural (CRZ-III A and III B). The Karnataka Tourism Policy 2020-26 has identified all three coastal districts as Focus Tourism Destinations, with KSCZMA clearance mandatory for any hotel, resort, jetty, or shack on the 92 beaches mapped in the CZMP Tourism Plan. The Karnataka Tourism Policy 2020-26 expires in 2026 — verify whether a successor policy has been notified before relying on tourism-permit assumptions.
The corridors most asked about, mapped against CRZ classification under the approved Karnataka CZMP.

The most misunderstood corridor is the Gokarna-Kumta-Honnavar belt. Buyers see beach-resort listings and assume CRZ-III B at 200 m NDZ is the only constraint. Eight municipalities along this stretch (Ullal, Mulki, Kundapura, Saligrama, Honnavar, Kumta, Ankola plus partial Bhatkal) have no sewerage network. Resort approvals in this belt now require sewage treatment as a condition of KSCZMA recommendation, regardless of zone classification.
