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.
