The Dilemma of Erroneous Mapping under the Coastal Regulation Zone Notification 2019: An Analysis of Remedial Procedures and Temporary Relief in Kerala
Sherry J. Thomas, Advocate, High Court of Kerala;sherryjthomas@gmail.com
Introduction
The implementation of the Coastal Regulation Zone (CRZ) Notification 2019 in the State of Kerala has been characterized by protracted administrative delays and significant spatial anomalies in the published Coastal Zone Management Plan (CZMP) maps. This article examines the systemic errors within the current CZMP, wherein substantial tracts of legally verified dry land have been misclassified as intertidal water bodies (Category CRZ-I B). Such cartographic errors directly impair the constitutional and statutory rights of local inhabitants to construct residential dwellings.
By analysing the procedural frameworks established under Annexure IV of the 2019 Notification and evaluating recent judicial interventions by the High Court of Kerala, this article highlights the friction between rigid environmental mapping practices and the practical socio-economic needs of coastal communities. Finally, it explores the formulation of interim judicial remedies designed to bypass bureaucratic delays and streamline localized permissions for small-scale residential developments.
The pragmatic and flexible implementation of Coastal Regulation Zone (CRZ) frameworks to accommodate the fundamental housing needs of local inhabitants is a long-pending demand of India’s coastal communities. While the central government promulgated the revised CRZ Notification in January 2019 to replace the legacy 2011 framework, its practical execution in Kerala faced severe institutional inertia. The comprehensive implementation of the 2019 Notification was delayed uninterruptedly for over five years, ultimately taking effect only in October 2024.
Despite the eventual operationalization of the Coastal Zone Management Plan (CZMP), the transition has been marred by widespread cartographic anomalies in the finalized spatial maps. The integration of erroneous baseline data into localized regulatory software—such as the state's K-SMART digital permit architecture—has effectively frozen legitimate local development of many coastal families.
Cartographic Anomalies and Spatial Errors in the CZMP
The primary grievance articulated by coastal property owners stems from the technical divergence between structural land records and the physical classifications imposed by the published CZMP maps. Under the statutory guidelines, state authorities were required to publish draft maps to invite public suggestions and objections before finalizing the spatial layouts. Although numerous local inhabitants submitted formal complaints pointing out clear geographic discrepancies, many critical errors persisted into the finalized document.
The Dry Land vs. Category CRZ-I B Conflict
The most disruptive error identified within the current CZMP is the systemic misclassification of unambiguous "dry land" (purayidam) as intertidal or ecologically fragile zones. In numerous instances, properties that are structurally categorized as dry land under municipal revenue records, and explicitly excluded from local paddy land and wetland data banks, have been designated as Category CRZ-I B zones, wherein construction is not permitted.
Statutory Definition:- Category CRZ-I B specifically denotes intertidal zones, infiltration ponds, and active water bodies located between the Low Tide Line (LTL) and the High Tide Line (HTL).
Regulatory Impact:- When dry land is legally treated as an active water body within the CZMP, local government bodies are statutorily prohibited from issuing building or occupancy permits.
Software Compounding:- Because the state's automated K-SMART permit application portal relies entirely on these erroneous spatial maps, applications for valid properties are automatically blocked, preventing any procedural advancement.
Anomalies in connection with sluice bund gates and Mangrove buffer zones
Pursuant to the amendment vide S.O. 4886(E) dated 26.11.2021, in paragraph 1, in clause (i), for the Explanation of CRZ Notification 2019, the requisite Explanation is substituted, so as to fix the HTL in case there exists a bund or a sluice gate constructed prior to the date of notification issued vide S.O. 114(E) dated 19th February, 1991, the HTL shall be restricted up to the line long along the bund or the sluice gate, however, in such a case, area under mangroves arising due to saline water ingress beyond the bund or sluice gate shall be classified as CRZ-IA irrespective of the extent of the area beyond the bund or sluice gate and such areas under mangroves shall be protected and shall not be diverted for any developmental activities. But all those sluice bund gates are not marked in the CZMP map.
It is further to be noted that as per the clause 1.1(b) of Annexure I of Notification 2019, mangroves in private land will not require a buffer zone. However, in several places in the present map even private lands are spotted as buffer zones near to Category 1A of CRZ.
Statutory Modification Procedures under Annexure IV of CRZ 2019
Resolving these spatial disputes requires adherence to the strict amendment protocols detailed within the CRZ Notification 2019. Specifically, Annexure IV of the CRZ 2019 Notification governs the formal design, verification, and periodic revision of Coastal Zone Management Plans.
The Role of Technology and Authorized Agencies
According to Clause 3 and Clause 4 of Annexure IV, any finalization or modification of coastal maps must rely strictly on the synthesis of Latest Ground Truth Verification. The Physical site inspections must also correlate revenue realities with coastal topology. High-Resolution Satellite Imagery must be used for utilizing advanced remote sensing data to delineate precise high and low tide lines.
The Clause 3 of Annexure IV of the CRZ 2019 Notification read thus:
3. Preparation of CZM Maps:
(i) Base Maps of 1:25,000 scale shall be acquired from the Survey of India (SOI) and wherever 1: 25,000 maps are not available, 1: 50,000 maps shall be enlarged to 1: 25,000 for the purpose of base map preparation and these maps will be of the standard specification given below:-
Unit : 7.5 minutes X 7.5minutes
Numbering : Survey of India Sheet Numbering System
Horizontal Datum : Everest or WGS 84
Vertical Datum : Mean Sea Level (MSL)
Topography : Topography in the SOI maps will be updated using latest satellite imageries or aerial photographs
(ii) Coastal Zone Management (CZM) Maps of scale 1:25,000 shall be got prepared by any of the agencies identified by the Ministry of Environment, Forest and Climate Change vide its Office Order number J-17011/8/92-IA-III dated the 14th March, 2014 using the demarcation of the High Tide Line or LTL, as carried out by NCSCM.
(iii) Various regulatory lines viz. at a distance of 20 metres, 50 metres, 200 metres and 500 metres from HTL respectively, as applicable in various CRZ categories, and the Hazard line shall be demarcated and transferred to the CZM maps.
(iv) HTL, LTL and CRZ boundaries, as applicable, shall also be demarcated in the CZM maps along the banks of tidal influenced inland water bodies.
(v) Classification of different coastal zones shall be done as per the CRZ notification and Standard national or international colour codes shall be used.
The clause 7 of Annexure IV of CRZ 2019 deals with revision of coastal zone management plan.
7. Revision of Coastal Zone Management Plans:
(i) Whenever there is a doubt, the concerned State or Union territory Coastal Zone Management Authority shall refer the matter to the National Centre for Sustainable Coastal Management who shall verify the CZMP based on latest satellite imagery and ground truthing.
(ii) If required, the rectified map shall be submitted to Ministry of Environment, Forest and Climate Change for consideration.
The Bureaucratic Challenge of Revision
When errors are officially contested, Clause 7 of Annexure IV dictates that if a structural doubt arises regarding spatial coordinates or boundary lines, the concerned State Coastal Zone Management Authority (KCZMA) cannot unilaterally alter the map. Instead, the matter must be formally referred to the National Centre for Sustainable Coastal Management (NCSCM) for technical verification. The NCSCM is tasked with reviewing the disputed tracts using real-time satellite imagery and ground-truthing data. This multi-tiered institutional pipeline makes the formal revision of a CZMP an exceptionally tedious, labor-intensive, and time-consuming administrative effort.
Judicial Interventions and Interim Relief Frameworks
Faced with administrative gridlock, some property owners moved the High Court of Kerala, filing writ petitions to contest the regulatory freeze on their lands. In a series of litigations—including W.P.(C) No. 3011, No. 4836, No. 9378, and No. 10496 of 2025; vide order dated 20.05.2026, the High Court of Kerala addressed the systemic failures of the state’s coastal mapping apparatus.
Field Verification via District Authorities
Recognizing that a full, formal map rectification via the NCSCM would take months or years, the High Court established an immediate, fact-finding mechanism through interim orders. The Court directed the District Collector—in their capacity as the Chairperson of the District Level Committee of the KCZMA—to execute urgent physical site inspections.
These inspections, conducted alongside village officers and local self-government secretaries, aimed to verify whether a disputed property was historically dry land or an active water body. In a substantial number of cases, these official field reports concluded that the properties were indeed dry land, contradicting the active CZMP data.
Policy Actions by the KCZMA
Prompted by judicial scrutiny and overwhelming field evidence, the KCZMA convened an extraordinary meeting on August 8, 2025. The Authority formally recorded minutes acknowledging the widespread complaints and authorized a structured modification protocol. The minutes of the meeting dated 8.8.2025 read thus:
"Proposal for modification of HTL in CZMP 2019 based on the applications received from individuals/local bodies
Decision: The Authority has examined the suggestions received for modification of HTL and it was decided to send the same NCSCM as the first phase for further corrections in HTL. It was also decided that any such complaints/suggestions received should be consolidated in 30 days for verification and submission to NCSCM."
Consolidation of Grievances:- The KCZMA resolved to aggregate all verified public and institutional complaints regarding HTL/LTL anomalies within a strict 30-day window.
NCSCM Referral: The initial phase of verified corrections was approved for transmission to the NCSCM for formal satellite data reconciliation.
Institutional Coordination: The KCZMA issued directives to the Principal Director of Local Self-Government Institutions, instructing local bodies to identify and map localized missing features—such as unrecorded sluice bund gates—that had contributed to the original flooding misclassifications.
The Exemption for dwelling units: Balancing Protection and Local Rights
The Clause 7(vi) of CRZ Notification 2019 specialized decentralization rules apply to local communities. It states that, for self-dwelling units up to a total built up area of 300 square meters, approval shall be accorded by the concerned local Authority, without the requirement of recommendations of concerned Coastal Zone Management Authority and such authorities shall, however, examine the proposal from the perspective of the Coastal Regulation Zone notification before according approval. Therefore, for any residential construction matching or falling below this 300 sq.mtr threshold, the statutory power to grant building approvals is vested directly within the concerned local self-government institution (such as the Municipality or Grama Panchayat), bypassing the need for a protracted clearance process from the state-level KCZMA.
The Judicial Resolution
The High Court held that local bodies cannot indefinitely withhold building permissions for small residential homes simply because a regional map correction process is pending at the national level. The Court ruled that where a property is physically verified as dry land and is otherwise compliant with building rules, the local authority must process the application independently of the pending CZMP map revision, provided the proposed dwelling does not exceed 300 Sq. Mtres. It is also made clear that if any building permit is issued, it will be subject to the final decision of the authorities concerned in connection with map correction. It is also clarified that if any of the building permit applications are rejected and if the petitioners want to submit any regularisation application, the petitioners are free to submit an appropriate application in accordance with the law.
Conclusion
The ongoing judicial management of Kerala’s coastal zone highlights a critical structural flaw - the vulnerability of digital governance systems to inaccurate baseline data. While environmental zoning relies on high-resolution satellite imagery, it must be balanced against ground realities and verified revenue histories.
The interim mechanisms shaped by the High Court of Kerala offer a balanced approach. By tasking district committees with swift field inspections and empowering local bodies to clear small-scale residential projects, the judiciary has protected local inhabitants from bureaucratic delays which are not their fault. Moving forward, the final resolution of these disputes requires close cooperation between the KCZMA, local institutions, and the NCSCM to ensure that upcoming environmental maps are both ecologically accurate and socially just.
