Coastal land reclamation is illegal when it is done inside the Coastal Regulation Zone without a specific clearance, and for most private purposes it cannot be cleared at all. The CRZ Notification, 2019 prohibits land reclamation, bunding and disturbing the natural course of seawater, with limited exceptions for things like ports, jetties, bridges, roads on stilts, defence works and erosion control. Even those need CRZ clearance and, for larger projects, environmental clearance. Filling a creek, mudflat or backwater for plots, a resort, a godown or a private road is almost always unlawful, and is often an encroachment on government land too.

Short answer: Reclaiming land from the sea, a creek, a mudflat or a backwater is prohibited in the CRZ unless it is for a permitted purpose such as a port, jetty, bridge, defence work or erosion control, and has CRZ clearance (plus EC where required). Private filling for plots, resorts or warehouses is generally illegal and can be stopped and reversed.

This guide explains what the law treats as reclamation, which projects can lawfully do it and on what conditions, who owns land taken from the sea, and how residents and fishing communities can stop illegal filling before it becomes permanent. It is part of our coverage of CRZ violations and mangrove destruction.

Where the filled area has mangroves on it, read this with our guide on mangrove cutting laws and penalties, because the penalties and the authorities differ. If the filling is in an inland lake or village pond rather than tidal water, the guide on illegal filling of a lake or pond is the better fit.

हिंदी में सारांश

समुद्र, खाड़ी (क्रीक), कीचड़ वाले तट (मडफ्लैट) या बैकवाटर को भरकर ज़मीन बनाना तटीय विनियमन क्षेत्र (CRZ) में आम तौर पर गैरकानूनी है। CRZ अधिसूचना 2019 भूमि पुनर्ग्रहण, बांध बनाने और समुद्री पानी के प्राकृतिक बहाव को रोकने पर रोक लगाती है। बंदरगाह, जेट्टी, पुल, खंभों पर बनी सड़क, रक्षा कार्य और कटाव रोकने जैसे कुछ कामों को ही मंज़ूरी मिल सकती है, वह भी CRZ क्लीयरेंस और ज़रूरत हो तो पर्यावरण मंज़ूरी के बाद। प्लॉट, रिसॉर्ट या गोदाम के लिए भराई लगभग हमेशा अवैध होती है। तटीय प्राधिकरण, कलेक्टर और NGT से इसे रुकवाया और हटवाया जा सकता है।

In short

The essentials

Default is no

Reclamation, bunding and blocking seawater are prohibited in the CRZ unless an exception applies.

Exceptions are narrow

Ports, jetties, bridges, defence works and erosion control can qualify, private plots cannot.

Clearance first

Permitted projects still need CRZ clearance and, where the EIA Notification applies, EC.

Tidal water counts

CRZ reaches up tidal creeks, rivers and backwaters, not just the open beach.

Often public land

Foreshore and tidal land is usually government land, so filling it is encroachment as well.

Act before it settles

A bund removed in month two is easy; a filled, built-on plot five years later is not.

The short answer

When is coastal land reclamation illegal?

Reclamation is illegal in three common situations. First, when it happens inside the CRZ for a purpose the notification does not permit, such as housing plots, a hotel, a warehouse, a parking area or a private access road. Second, when the purpose is permitted but the project has no CRZ clearance, or has reclaimed more area than it was cleared for, or ignored the conditions. Third, when the area is also protected by another law, for instance mangroves, a notified wetland or forest land.

The CRZ Notification, 2019, made under the Environment (Protection) Act, lists land reclamation, bunding and disturbing the natural course of seawater among prohibited activities. It then carves out exceptions for foreshore facilities like ports, harbours, jetties, wharves, quays and slipways, for bridges, sea links and roads on stilts, for defence and security works, for measures to control erosion and maintain or clean waterways, and for facilities essential to activities the notification otherwise allows. Each of these still needs clearance through the coastal zone management authority, and many also need environmental clearance under the EIA Notification, 2006.

So the useful question is not whether a project is big or small, but whether it falls in one of those exceptions and holds a clearance that covers exactly what is being filled. If the answer to either is no, the filling can be stopped, and the area can be ordered restored.

Definitions

What counts as reclamation?

Reclamation is any act that turns land covered or influenced by tidal water into dry land. Pouring soil into the sea is the obvious case. The everyday cases are quieter: raising a low-lying backwater plot by a metre with earth from a construction site, extending a compound wall into a creek a little each year, building a bund that cuts off a mudflat from the tide and then levelling it, or converting saltpans and old aquaculture ponds into building land.

Bunding is treated as seriously as filling, because a bund changes how the tide moves even before any soil is dumped behind it. Water that used to spread across a mudflat now pushes against neighbouring land, drains slower in the monsoon and stops carrying fish larvae into the creek. That is why the notification bans disturbing the natural course of seawater separately from reclamation.

Erosion protection is different. A sea wall, groyne or rock armouring built to protect existing land or a village, with clearance, is allowed by the notification. Problems start when an erosion-control work is used as cover to push the shoreline outward and create new land behind it. In disputes, the before-and-after high tide line on the approved map usually settles which one it was.

The law

The laws that govern coastal reclamation

CRZ Notification 2019

Prohibits reclamation, bunding and disturbing the natural course of seawater except for listed purposes. It divides the coast into CRZ-I to CRZ-IV, applies along tidal creeks, rivers and backwaters up to the limit of tidal influence, and works through approved Coastal Zone Management Plans prepared for each coastal state.

EIA Notification 2006

Ports, harbours and many large coastal infrastructure projects need prior environmental clearance, and the EIA should describe the reclamation, the source of fill material and the effect on tides and fishing. Category A projects and many B1 projects need a public hearing. An EC can be appealed to the NGT within 30 days under section 16 of the NGT Act.

Wetlands Rules 2017

In notified wetlands, which can include coastal lagoons and backwaters, reclamation, encroachment and dumping are prohibited. The state wetland authority enforces them.

Constitution and state land law

Article 297 of the Constitution vests lands and things of value underlying the ocean within territorial waters in the Union. Foreshore and tidal land is generally treated as government land under state revenue law, so private filling of such land is usually also an encroachment the Collector can remove.

Waste rules

Fill material is often construction and demolition debris, fly ash or mixed garbage. Dumping it into a creek breaks the Construction and Demolition Waste Management Rules, the Solid Waste Management Rules, 2026 and, for fly ash, the 2021 utilisation notification, which gives a separate handle on the dumper and the transporter.

Ownership

Who owns land reclaimed from the sea?

Usually not the person who filled it. Land below the high tide line and tidal creeks is generally government land, and reclaiming it does not create private title. We meet buyers who hold a registered sale deed for a plot that, on the old revenue map, is shown as creek or khajan land. The deed records a transaction, but it cannot convert public tidal land into private property or override the CRZ.

Where the land was genuinely private before, for example an old saltpan or a paddy field behind a traditional embankment, ownership is not in doubt but use still is. Private ownership does not exempt land from the CRZ, so raising and building on it remains subject to the zone rules and the approved map.

Government reclamation for public purposes is a separate story. A port authority or a state agency reclaiming land for a terminal or a coastal road does so on land it controls, under clearances. The legal challenge there is not about title but about whether the clearance was properly granted and whether its conditions are being met.

Maps

How do I check whether the site is in the CRZ?

Start with the approved Coastal Zone Management Plan for your district. The CZMP maps show the high tide line, the low tide line, the CRZ categories, mangroves and other sensitive areas, and the limit of tidal influence up creeks and rivers. Coastal zone management authorities publish them, and you can ask for a certified extract for a particular survey number by RTI.

Do not rely on what the high tide line looks like on the ground today. Reclamation is exactly the activity that moves it. If someone has filled a creek, the water will now stop further out, and they will argue the site is beyond the CRZ. The approved map, prepared before the filling, is what counts. Historical satellite images available free online are useful to show the creek or mudflat as it was.

For the rules on what can be built at each distance from the shore, see our guide on construction near the high tide line. For how CRZ approvals work on the project side, our page on CRZ clearance sets out the process.

Big projects

Ports, coastal roads and large reclamation: what can be challenged?

A permitted purpose is not a blank cheque. Large reclamation projects come with an EIA, a public hearing in most cases, a CRZ recommendation from the state authority, and a clearance with conditions. Challenges succeed when something in that chain is missing or wrong: the EIA did not disclose the full area to be reclaimed, the tidal and siltation studies were thin or copied, the public hearing was not properly notified to fishing villages, or the clearance quietly allowed commercial real estate on reclaimed land that has nothing to do with the port.

The deadline is strict. An appeal against an environmental clearance must reach the NGT within 30 days of the order being communicated, with up to 60 more days for sufficient cause. Our guide on objections at an EIA public hearing explains how to build the record at the hearing stage, which is when it matters most. The hub page on challenging an environmental clearance covers the appeal itself.

Once a project is running, the usual problem is breach of conditions: reclaiming beyond the approved boundary, dumping dredged material in the wrong place, blocking creeks that the conditions said must stay open, or skipping the monitoring of shoreline change. These can be raised before the MoEFCC regional office and the coastal authority, and then before the NGT under section 14. Advocate B.K. Singh's approach in condition-breach matters is to get the clearance letter, the half-yearly compliance reports and recent satellite images side by side, because the gap between the three is usually the case.

Quick checks

Questions to ask about any reclamation near you

  • Is the site inside the CRZ on the approved CZMP map, including tidal creeks and backwaters?
  • Is the purpose one the notification allows (port, jetty, bridge, defence, erosion control)?
  • Is there a CRZ clearance, and does it cover this exact area and activity?
  • Does the project need environmental clearance, and has it been granted?
  • Are there mangroves, a notified wetland or forest land in the filled area?
  • Where is the fill coming from: debris, fly ash, dredged sand, quarry material?
  • Has any creek, drain or tidal channel been blocked or narrowed?
  • When did the filling start, and when was the latest fresh dumping?
Step by step

How to stop illegal reclamation

Speed is everything with reclamation. A loose heap of debris can be removed; a compacted, built-on plot rarely is.

1

Document it from day one

Photograph and video the filling with date and location on, from fixed points, every few days. Record truck numbers, the time of dumping and any machine working on site.

2

Pin down the location and status

Note GPS coordinates and the survey number. File an RTI with the state coastal zone management authority asking for the CZMP extract and any CRZ clearance for that site, and with the Collector or tehsil for the land record.

3

Complain to all the authorities at once

Write to the coastal zone authority (or its district committee), the District Collector, the State Pollution Control Board and the municipal or panchayat body. Ask for an immediate stop to the filling, a site inspection and removal of the material. Add the forest department if mangroves are involved and the state wetland authority if it is a notified wetland.

4

Use local power for quick stops

The Collector or tehsildar can act against encroachment on government land, and the SDM can act against a public nuisance under section 152 of the BNSS where filling is causing flooding or blocking a public waterway. These are often faster than the coastal authority.

5

Ask what was done

Two or three weeks later, file RTIs for the inspection report and any notice issued. Keep copies of everything, because they show the tribunal that the authorities knew.

6

Approach the NGT with interim relief

If filling continues, file an original application under section 14 within 6 months, asking for an immediate order to stop work, a joint inspection, removal of fill and restoration of tidal flow. Ask for interim relief at the first hearing.

Our guide on interim relief and stay orders in the NGT explains what the tribunal needs to see before it stops work at the first hearing.

Why it matters

The harm reclamation causes, and why it gives you standing

Reclamation damage is usually felt by people who are not on the filled land at all. A filled creek mouth means the village behind it floods for longer in the monsoon. A bunded mudflat means fewer prawns and crabs in the creek, because that mudflat was their nursery. A new embankment can push erosion onto the next beach. These effects are what make a complaint concrete, and they are worth recording: water levels after heavy rain, catch records, photos of erosion on neighbouring land.

Under section 18 of the NGT Act, any person aggrieved, including a representative body, can apply. A fishermen's cooperative, a panchayat, a residents' association or a group of villagers all qualify. Where individuals have suffered loss, such as damaged boats or lost fishing days, a separate compensation claim can be made under section 15 within 5 years. For fishing-specific remedies, our guide on port and marine pollution remedies for fishermen goes into detail.

Illustration

A backwater plot that kept growing

Here's a made-up example. A landowner on a tidal backwater holds a small plot with a compound wall. Over two years, the wall moves outward a few metres at a time, and debris from city construction sites is tipped behind it. Neighbouring families notice their homes now flood for days after heavy rain, and a creek where they set crab traps has silted up.

They get the CZMP extract by RTI, which shows the area beyond the old wall as CRZ-I and the creek as tidal water. Historical satellite images confirm the wall's original line. Complaints to the coastal authority and the tehsildar lead to an inspection that records the encroachment, but no removal follows. Within six months of the latest dumping, they approach the NGT.

A tribunal in a case like this would likely form a joint committee, order the filling stopped, and direct removal of the fill to the original line, reopening of the creek and environmental compensation, while leaving the revenue authorities to deal with the encroachment on government land. Any construction raised on the filled strip would be at serious risk.

Choosing the forum

NGT, High Court or civil court?

The NGT is the natural forum when the complaint is environmental: CRZ violation, loss of tidal flow, damage to mangroves or wetlands, pollution from fill material, or breach of EC conditions. It can order restoration and compensation, and it works through site inspections rather than long trials. Bench depends on the state, with the western coastal states at Pune, the southern ones at Chennai, and West Bengal and Odisha at Kolkata.

A pure title dispute, such as two private parties arguing over who owns a reclaimed strip, belongs in the civil court. A challenge to a state policy, a legislative change or a failure of authorities that goes beyond the NGT Act's subjects may need a writ petition in the High Court. Our guide on choosing between a High Court writ and an NGT case sets out the differences. Filing in two forums on the same facts usually backfires, so pick one main route.

Do not wait for perfect evidence. The 6-month limit under section 14 runs from when the cause of action first arose, and arguments about continuing wrongs are uncertain. Our guide on NGT time limits explains how the clock is counted.

Buyers

If you have bought land or a flat on reclaimed land

Check before you pay, if you still can. Ask the seller for the CZMP extract for the survey number, any CRZ clearance, and the land record showing what the land was classified as before. A plot that was creek, salt marsh or mangrove on old records is a red flag whatever the sale deed says.

If you have already bought and a notice arrives, do not ignore it and do not continue construction. Reply on facts with documents, and get advice on whether the site truly falls in a prohibited category. Advocate B.K. Singh often finds that the most useful document for a buyer is the seller's own disclosure: if the seller hid the CRZ status, the buyer has a claim against the seller or developer even if the structure cannot be saved.

FAQs

Frequently Asked Questions

Is land reclamation legal in India?

Only for permitted purposes such as ports, jetties, bridges, roads on stilts, defence works and erosion control, and only with CRZ clearance and EC where required. Private reclamation for plots or buildings in the CRZ is prohibited.

Can I fill a creek or backwater on my own land?

Generally no. Tidal creeks and backwaters are within the CRZ up to the limit of tidal influence, and filling or bunding them is prohibited even on private land.

Who owns land reclaimed from the sea?

Land below the high tide line and tidal creeks is generally government land, and filling it does not create private ownership. The Collector can treat it as encroachment.

Does a port need permission to reclaim land?

Yes. A port or harbour needs CRZ clearance and environmental clearance, and the reclamation must stay within the approved area and conditions.

How do I know if a site is in the CRZ?

Check the approved Coastal Zone Management Plan map for the survey number. You can get a certified extract from the state coastal zone management authority through RTI.

Is bunding allowed in the CRZ?

No, except as part of a permitted and cleared activity. The CRZ Notification separately prohibits bunding and disturbing the natural course of seawater.

Can the NGT order reclaimed land to be restored?

Yes. The NGT can order the filling stopped, the material removed, tidal flow restored and environmental compensation paid by the violator.

How long do I have to challenge a reclamation project's clearance?

An appeal against an environmental clearance must be filed in the NGT within 30 days of communication, extendable by up to 60 days for sufficient cause.

Can fishermen complain about reclamation?

Yes. Any person aggrieved, including a fishermen's cooperative or village body, can apply to the NGT, and individuals can also claim compensation for their losses within 5 years.

Is a sea wall the same as reclamation?

No. A sea wall built with clearance to protect existing land is allowed, but using it to push the shoreline outward and create new land is illegal reclamation.

What if the land was already filled years ago?

Restoration is still possible, but delay weakens the case and the 6-month limit for fresh NGT applications may be an issue. Get the old maps and act as soon as you can.
