CZMA PIL Counsel

Environmental matters move on paperwork and deadlines. This page sets out how CRZ clearance, wetlands, mangroves, floodplains and eco-sensitive zones works in practice where the CZMA is involved. Legals365 is the legal platform of Advocate B.K. Singh and associates, who appear before pollution control boards, the NGT and the courts.

In short. Land near the coast, a mangrove, a notified wetland, a river floodplain or a protected area carries extra restrictions under the Environment (Protection) Act 1986. Coastal projects need CRZ clearance under the CRZ Notification 2019, wetlands are governed by the Wetlands Rules 2017, and eco-sensitive zones have their own notifications. Violations can lead to stop-work orders, demolition and environmental compensation, usually decided by the NGT.

Most environmental approvals turn on what a project does: what it burns, discharges or stores. The rules on coasts, wetlands, mangroves, floodplains and eco-sensitive zones turn on where it sits. A small house, a resort, a warehouse or a road can be perfectly lawful on one plot and unlawful two hundred metres away, because the second plot falls inside a no development zone, a wetland boundary or a notified eco-sensitive zone. That is why these disputes so often involve ordinary landowners, homebuyers and builders, not only factories.

This page explains the main regimes, who grants clearance, what is prohibited, how enforcement works and where you go when a notice arrives or when you want to stop a violation. The answer changes with the type of project, the state, the map that applies and which side of the dispute you are on (building or objecting), so each section says how those details shift the position.

What these location-based rules actually restrict

These rules restrict what can be built or done in an ecologically sensitive place, regardless of whether the activity itself pollutes. The coastal regulation zone controls the coastline and tidal water bodies, the Wetlands Rules control notified wetlands and the land around them, eco-sensitive zones control a buffer around national parks and wildlife sanctuaries, and floodplain restrictions come mostly from master plans, state laws and orders of the National Green Tribunal.

All four draw their force from the Environment (Protection) Act 1986. Section 3 lets the Central Government restrict industries, operations and processes in specified areas, and the CRZ Notification, the Wetlands Rules and ESZ notifications are all made under it. Section 5 lets the government or a delegated authority issue binding directions, including directions to stop work, close a unit or remove a structure. That is why a CZMA or a wetland authority can issue a demolition direction without first going to court.

In practice the restriction usually bites at three moments: when you apply for building plan approval or an environmental clearance, when someone complains about construction already under way, and when you try to sell or finance the property and a buyer's lawyer or the bank asks for the CRZ or ESZ status. A problem caught at the first stage costs a redesign. Caught at the third, it can mean a structure that cannot be regularised.

The four regimes side by side

The provisions you will see cited

CRZ zones in plain terms

The CRZ covers the land from the high tide line up to 500 metres inland along the sea, the intertidal area, the sea up to 12 nautical miles, and a strip along tidal creeks, backwaters and estuaries. Along tidal water bodies the landward strip is usually 50 metres or the width of the water body, whichever is less. The high tide line is not a line you can see on site; it is demarcated by an authorised agency and drawn on the approved Coastal Zone Management Plan.

CRZ-I covers ecologically sensitive areas such as mangroves, coral reefs, sand dunes and turtle nesting sites (CRZ-I A) and the intertidal zone (CRZ-I B). CRZ-II covers developed, largely built-up areas within municipal limits, where construction is allowed broadly on the landward side of existing roads or authorised structures and as per the town planning norms in force. CRZ-III covers rural and relatively undisturbed areas. Under the 2019 notification it is split into CRZ-III A, densely populated areas with a no development zone of 50 metres, and CRZ-III B, with a no development zone of 200 metres. CRZ-IV covers the water area itself.

The category decides almost everything: whether a hotel is allowed, how close it can come to the water, whether a fisherman's house can be rebuilt, and who grants permission. People often assume their village is CRZ-II because it looks built up. If the approved plan shows it as CRZ-III, the stricter rules apply until the plan is revised.

When CRZ clearance is needed and who grants it

CRZ clearance is needed for any permissible project or activity inside the CRZ that the notification lists as requiring it, which covers most construction other than minor repairs and the housing needs of local communities as permitted. Projects in CRZ-I and CRZ-IV, such as ports, jetties, pipelines, desalination plants and coastal roads, are cleared by the MoEFCC on the recommendation of the State CZMA. Projects in CRZ-II and CRZ-III are generally cleared by the state or UT environment department, again on the CZMA's recommendation, with local planning approvals following.

If a project also needs environmental clearance under the EIA Notification 2006, the two are appraised together and a single letter usually records both. A project that falls within 10 kilometres of a protected area, or close to a notified eco-sensitive area, can move from category B to category A under the EIA Notification's general condition, which shifts the appraisal from the state to the Centre. Our page on environmental clearance and EC violations covers that side in detail.

For individual houses and small commercial buildings in CRZ-II, the local body often processes the CRZ aspect through the CZMA as part of building plan approval. The CZMA's recommendation then becomes a condition of the sanctioned plan. Building first and asking for CRZ approval later is the single most common reason demolition orders are passed.

How a CRZ clearance application moves

The outline below applies to most projects; exact forms and fees are set by each state CZMA.

1. Confirm the category on the approved map

   Get the relevant sheet of the approved Coastal Zone Management Plan and plot the site on it. If the HTL or the CRZ boundary is unclear, get a site-specific demarcation from an agency authorised by the MoEFCC, because the CZMA will rely on that report.

2. Check permissibility before design

   Compare the proposed use against the prohibited and permissible lists for that CRZ category. Fix setbacks, height and floor area so that the plan complies; a CZMA will not redesign your project for you.

3. Prepare the application

   File Form 1 or the state's equivalent with the CRZ map superimposed with the project layout, the demarcation report, project details, waste and sewage arrangements and, where required, a rapid EIA or disaster management plan.

4. CZMA scrutiny and recommendation

   The State CZMA examines the file at its meeting, may seek clarification or a site visit, and forwards its recommendation to the state department or the MoEFCC. Answer queries in writing and keep copies of minutes once published.

5. Clearance and conditions

   The clearance letter will carry specific and general conditions. Comply with them and file the compliance reports that the letter requires, because breach of a condition is treated like building without clearance.

Anyone aggrieved by the grant or refusal can appeal to the NGT within 30 days of communication, so a builder should expect that a clearance may be tested by neighbours or fishing communities before construction starts.

Mangroves: why even a small patch matters

Mangroves are treated as CRZ-I A, the most protected category, and cutting, filling or dumping on them is prohibited except for limited public projects cleared with compensatory planting. A buffer zone of 50 metres is prescribed along larger mangrove areas (more than 1,000 square metres), and no construction is permitted in that buffer. Where mangrove land is government land, several states have also notified it as protected or reserved forest, which brings in the Forest (Conservation) Act and its own clearance process.

Mangrove cases usually begin with a complaint about debris dumping or a boundary wall at night. The authority's response is a stop-work direction and a restoration order, often with environmental compensation. For an owner, the important point is that the mangrove status of land can exist even if revenue records describe it as agricultural or salt pan land, because the classification follows what is on the ground and on the CZMP map.

If you are buying coastal land, ask for a mangrove survey report and recent satellite imagery. Clearing mangroves before purchase does not help: authorities and the NGT routinely compare older satellite images and treat the land as mangrove land that has to be restored. Related tree cutting and forest questions are covered on our forest clearance and tree cutting page.

Wetlands, lakes and village ponds

Notified wetlands are protected by the Wetlands Rules 2017, and the prohibited list in rule 4 applies once a wetland is notified by the state government on the recommendation of the State Wetlands Authority. Prohibited activities include converting the wetland to non-wetland use, encroachment, setting up or expanding industries, handling hazardous substances, dumping solid waste or construction debris, discharging untreated effluent or sewage, and permanent construction (other than boat jetties) within 50 metres of the mean high flood level observed over the previous ten years. The definition excludes river channels, paddy fields and certain human-made water bodies such as those built for irrigation or aquaculture.

The harder question is the wetland that has not been notified. Courts and the NGT have repeatedly treated lakes, ponds and johads as public trust resources even without notification, and the Supreme Court has directed states to identify and map wetlands. In Uttar Pradesh, land recorded as a pond (talab or pokhar) is public utility land under the UP Revenue Code 2006, and encroachment can be removed by the Tehsildar under the Code's eviction provisions. In Delhi, the Delhi Wetland Authority and the land-owning agency, often DDA, take action on encroached water bodies.

For a buyer, the warning signs are a khasra entry showing water, low-lying land that floods every monsoon, or a plot sold cheaply next to a lake. For a society or industrial unit, the common risk is discharge into a nearby pond or drain that feeds a wetland. Our page on sewage discharge and STP compliance explains what the boards expect on that front.

Floodplains: Yamuna, Hindon and other rivers

There is no single national floodplain law, so floodplain restrictions come from the master plan, the state's river or drainage law, the irrigation department's demarcation and orders of the NGT. In Delhi, most of the Yamuna floodplain falls in Zone O of the Master Plan, and the NGT has prohibited new construction and debris dumping on the demarcated floodplain, with environmental compensation for violators. DDA and the irrigation and flood control department carry out demolitions, often after a public notice rather than individual notice to each occupant.

Around Noida and Ghaziabad, the Yamuna and Hindon floodplains have seen repeated demolition drives against farmhouses, colonies and godowns built on land that was sold through agreements, GPAs or unregistered documents. The NGT has directed demarcation of the floodplain and action against construction within it. Buyers in those areas often discover that the seller's title was perfectly real but the land use was never permissible. For the Ganga and its tributaries, the River Ganga authorities order of 2016 under the EP Act adds restrictions on construction and dumping near the river.

Floodplain cases are usually decided on maps. The questions are where the demarcated boundary runs, which flood frequency it is based on, whether your structure predates the demarcation, and whether the authority followed its own notice procedure. Those questions have answers in documents, which is why the first step is always to collect the demarcation map and your own title and approval papers before the next demolition date.

Eco-sensitive zones around parks and sanctuaries

An eco-sensitive zone (ESZ) is a buffer around a national park or wildlife sanctuary, notified by the MoEFCC under rule 5 of the Environment (Protection) Rules 1986. Each notification is area-specific. It fixes the boundary, which can range from a few hundred metres to several kilometres, and lists prohibited activities (typically commercial mining, polluting industries, major hydroelectric projects and stone crushing), regulated activities (such as hotels, felling of trees and widening of roads) and permitted activities (such as farming and rainwater harvesting). The state must prepare a zonal master plan, and a monitoring committee supervises compliance.

Where no ESZ was notified, a default buffer was long applied for approvals. In June 2022 the Supreme Court directed a minimum ESZ of one kilometre around protected areas; in April 2023 it modified that direction so that it does not apply where final or draft ESZ notifications exist and is not a uniform rule across the country. Check the current position and the specific notification for the sanctuary concerned. In Delhi NCR, the ESZs around the Asola Bhatti Wildlife Sanctuary and the Okhla Bird Sanctuary have affected construction approvals in south Delhi, Faridabad and Noida.

An ESZ does not take away ownership. Farmers continue to farm, and existing houses stay. What changes is the use you can make of the land and the approvals you need, which can sharply reduce its value for development. One point owners miss: the Wild Life (Protection) Act is not one of the NGT's Schedule I Acts, so a dispute purely under that Act goes to the High Court, while a dispute under the ESZ notification, being made under the EP Act, can go to the NGT.

How the position differs for buyers, builders, industries and local residents

A flat or plot buyer is mainly concerned with whether the building is lawful and saleable. Ask the builder for the CRZ clearance or CZMA recommendation, the EC if the project size requires one, and confirmation that the project is outside any ESZ, wetland or floodplain boundary. If a registered RERA project later faces a CRZ or floodplain problem, buyers can use RERA complaints against the builder for refund or interest, but RERA cannot overrule an environmental prohibition.

A builder or developer carries the approval risk and should treat these rules as part of land due diligence, along with title and land use. A bank financing the project will usually ask for the same papers, and a lender's legal opinion that ignores CRZ or ESZ status is incomplete. An industrial unit has an extra layer, because its consent to operate from the pollution control board does not cure a location that is prohibited under a CRZ or ESZ notification.

Local residents, fishing communities and traditional landholders have a different interest. The CRZ Notification 2019 protects the dwelling units and livelihood activities of traditional coastal communities, and permits reconstruction of their houses within limits. Farmers inside an ESZ can continue agriculture. If you are a resident objecting to a project, your strongest arguments are usually map-based: the project sits in a no development zone, the clearance relied on a wrong demarcation, or a wetland was left out of the baseline survey.

Documents to collect

Stop-work orders, demolition notices and how to respond

A notice from a CZMA, wetland authority, development authority or district administration usually asks you to stop work, show cause why the structure should not be removed, or restore the site. Reply within the time given, in writing, and attach documents rather than making general claims. The reply should deal with three things: whether the site is actually inside the restricted area, whether the structure predates the restriction or was approved, and whether the activity is permitted in that category.

If the authority has not given you a hearing, or has relied on a demarcation you were never shown, say so and ask for the record. Many orders fail on procedure, not on merits. If the notice demands environmental compensation as well, deal with the amount separately; our page on challenging an environmental compensation demand explains how those figures are worked out. For a general show cause notice, see our guide to replying to a pollution board show cause notice.

When a coastal or floodplain notice reaches Advocate B.K. Singh's office, the first thing he looks for is the map the authority relied on and its date, because the notice and the approved plan often do not match. If the order is final and demolition is imminent, the remedy is an appeal to the NGT with an application for stay, or in some cases a writ petition before the High Court. Do not continue construction after a stop-work direction; it destroys the argument that you acted in good faith.

Which forum hears these disputes

The National Green Tribunal is the main forum. Appeals against grant or refusal of CRZ clearance, EC and directions under section 5 of the EP Act go to it under section 16 within 30 days, extendable by 60 days for sufficient cause. Original applications raising a substantial question relating to the environment, such as a wetland being filled or a floodplain encroached, go under section 14 within six months of the cause of action, and claims for relief and compensation under section 15 within five years. Our page on filing and defending a case in the NGT explains the procedure.

The High Court under Article 226 hears matters outside the NGT's statutes, such as pure wildlife law questions, challenges to the validity of a notification, and some cases where the grievance is mainly about natural justice by a state authority. An NGT order is appealed to the Supreme Court under section 22 within 90 days, through an Advocate-on-Record; see our page on Supreme Court appeals.

Civil courts, revenue courts, consumer commissions and RERA do not decide whether a structure violates the CRZ, wetland or ESZ rules. A revenue court may decide whether land is recorded as a pond or gram sabha land, and RERA may give a buyer a refund, but the environmental question itself belongs to the authorities and the NGT. Larger public interest challenges are covered on our page on environmental PILs, stays and contempt.

Mistakes that make these cases worse

• Relying on revenue records alone. A khatauni entry saying agricultural land tells you nothing about CRZ, ESZ or floodplain status. Check the environmental maps separately.
• Building first and seeking approval later. Post-facto approval is rarely available for CRZ or wetland violations, and authorities treat it as deliberate.
• Filing a civil suit for injunction. Section 29 of the NGT Act bars civil courts from these questions, so the suit wastes months and can be dismissed at the start.
• Ignoring a public notice. Floodplain and wetland drives often rely on public notices. Saying you never got a personal notice rarely saves the structure.
• Missing the 30-day NGT window. Appeals against clearances and directions are time-bound. Delay beyond 90 days in total cannot be condoned under section 16.
• Arguing equity instead of maps. Sympathy for a family home does not override a no development zone. The arguments that work are about boundaries, dates and procedure.

Raising a complaint about a violation

If you want to stop mangrove cutting, wetland filling or floodplain construction, start with a written complaint to the authority that has the power to act: the State CZMA for coastal matters, the State Wetlands Authority or district administration for wetlands, the development authority or irrigation department for floodplains, and the ESZ monitoring committee or forest department for eco-sensitive zones. Attach photographs with dates and location, and ask for a site inspection.

If the authority does not act within a reasonable time, an original application before the NGT under section 14 is the usual next step. The NGT generally forms a joint committee of the authorities to inspect and report, and then passes directions on restoration and compensation. Keep your application factual and supported. Applications that read as private disputes dressed up as environmental cases are dismissed, and sometimes with costs.

In complaints that come to Advocate B.K. Singh, the deciding factor is often the quality of the first evidence: a dated video showing debris trucks entering a wetland at night is worth more than pages of argument. Collect it before you file, because the site can be levelled quickly once the other side knows a case is coming.

Cost, time and what to do this week

Costs depend on the stage. Advice and due diligence before purchase are modest compared with litigation, because the work is mostly reading maps and notifications. A reply to a notice involves document collection and a hearing. An NGT appeal or original application involves court fees, which are low where no compensation is claimed, plus the cost of experts or surveyors if the boundary is disputed. NGT matters often get a first hearing quickly, but final disposal can take months, especially if a joint committee is appointed.

This week, if you have a notice: note the reply date, collect the documents listed above, get the CZMP sheet, wetland boundary, floodplain map or ESZ notification that applies, and stop any ongoing construction. If you are buying: ask the seller or builder in writing for CRZ, ESZ, wetland and floodplain confirmation, and have the title and approvals checked together through a property verification. If you are complaining: collect dated evidence and send a written complaint to the right authority.

If you want the papers checked before you act, the team of Advocate B.K. Singh at Legals365 can review them and tell you the next step; you can talk to a lawyer here.

Coastal zone authorities and CRZ clearance

Coastal Zone Management Authorities regulate building and activity along the coast. There is a national authority and one for each coastal state and union territory, all set up under section 3(3) of the Environment (Protection) Act 1986. They enforce the Coastal Regulation Zone Notification 2019, or the 2011 notification in areas where the coastal zone management plan under the 2019 rules is not yet in force. Anyone buying, building or litigating over land near the sea, a creek, a backwater or a tidal river should check the CRZ status of the plot before anything else, because it can override a building plan sanction granted by the local body.

The notification divides the coast into zones. CRZ I covers ecologically sensitive areas such as mangroves, coral reefs and the intertidal zone, where almost nothing may be built. CRZ II covers developed urban areas, where construction follows local building rules subject to the CRZ limits. CRZ III covers rural and less developed areas, with a no development zone of 50 or 200 metres from the high tide line depending on population density, and CRZ IV covers the water area. The high tide line itself is marked on approved maps, and disputes often turn on where that line lies and which map applies.

The CZMA examines proposals and recommends them. Projects in CRZ I and CRZ IV, and certain larger projects, need clearance from the MoEFCC after the state authority's recommendation, while many smaller projects in CRZ II and III are cleared by the state authority or permitted by the local body in line with the plan. Applications need the approved CRZ map showing the site, a survey by an authorised agency, project details and, for larger projects, an environmental study. The authority can also take action against violations: it can issue show cause notices, order work to stop and recommend demolition.

Violations are taken seriously by the courts. The Supreme Court ordered the demolition of apartment towers at Maradu in Kochi for CRZ violations despite the buildings being occupied, and buyers there were left seeking compensation from builders. Resorts, homestays and second homes in Goa, Kerala, Maharashtra and other coastal states are frequent subjects of complaints and NGT applications. Buyers based in Delhi NCR often learn of the problem only when a notice arrives, so CRZ clearance or a certificate that the plot lies outside CRZ should be part of the title check.

Orders granting or refusing CRZ clearance are usually challenged before the NGT, at the zonal bench for the coastal state, while procedural complaints about the authority can go to the High Court in a writ. A representation to the CZMA, with survey maps and the history of the structure, is often the first step where the dispute is about whether a structure is old or lies inside the zone.

Frequently asked questions

What is CRZ clearance and when is it needed?

CRZ clearance is permission under the CRZ Notification 2019 for a project inside the coastal regulation zone. It is needed for most construction and permissible projects in CRZ areas, apart from limited repairs and the housing of traditional coastal communities as allowed. Projects in CRZ-I and CRZ-IV are cleared by the MoEFCC; those in CRZ-II and CRZ-III by the state or UT on the CZMA's recommendation.

How far from the sea does the CRZ extend?

On the seafront it extends 500 metres inland from the high tide line, along with the intertidal zone and the sea up to 12 nautical miles. Along tidal creeks and backwaters the landward strip is usually 50 metres or the width of the water body, whichever is less. The exact boundary is shown on the state's approved Coastal Zone Management Plan.

Can a house built in a CRZ area without clearance be regularised?

Generally no. Post-facto CRZ approval is rarely granted, and courts have ordered demolition of large buildings that came up in violation. Limited relief may exist for traditional coastal community dwellings or for structures that predate the restriction, so the date of construction and the category matter.

Is cutting mangroves a criminal offence?

Cutting mangroves violates the CRZ Notification and, where the land is forest, the forest laws. Under the EP Act as amended in 2023, most contraventions now attract monetary penalties through an adjudicating officer, but restoration orders, environmental compensation and action under forest law can also follow. The authority will usually require the site to be restored.

What activities are banned in a notified wetland?

Rule 4 of the Wetlands Rules 2017 bans conversion to non-wetland use, encroachment, new or expanded industry, dumping of waste and debris, discharge of untreated effluent, and permanent construction near the wetland except boat jetties. Other activities are regulated by the State Wetlands Authority. The rules apply in full once the wetland is notified.

Can I build on land in the Yamuna floodplain in Delhi?

No new construction is permitted on the demarcated Yamuna floodplain, which falls largely in Zone O of the Master Plan, and the NGT has directed action against encroachments. Land bought through agreements or GPAs in these areas has repeatedly been cleared by DDA. Check the demarcation before buying anything near the river.

What is an eco-sensitive zone and does it take away my land?

An eco-sensitive zone is a notified buffer around a national park or wildlife sanctuary where some activities are banned and others regulated. It does not take away ownership, and farming and existing homes continue. It does limit new development, so the land's value for construction can drop.

Which court hears a CRZ or wetland dispute?

The National Green Tribunal, because these rules are made under the Environment (Protection) Act, a Schedule I Act. Appeals against clearances and directions go under section 16 within 30 days, and original applications under section 14 within six months. Civil courts are barred under section 29 of the NGT Act.

Can I file a civil suit to stop a demolition by the floodplain authority?

Usually not. Section 29 of the NGT Act bars civil courts from matters the NGT can decide, and the civil court cannot decide whether land falls in a protected floodplain. The proper remedy is a reply and hearing before the authority, then an NGT appeal or a High Court writ.

How do I check whether a plot is in a CRZ, ESZ or wetland area?

Get the relevant sheet of the approved Coastal Zone Management Plan, the ESZ notification for any nearby sanctuary, and the state wetland list or boundary. Compare them with revenue maps and recent satellite images. A lawyer and surveyor can plot the site accurately where the boundary is close.

Does a consent to operate from the pollution board cover a CRZ problem?

No. Consent to operate under the Water and Air Acts deals with emissions and discharges, not location. A unit that is prohibited in a CRZ or ESZ category cannot rely on its consent to defend the location.

How long does an NGT case on a wetland or floodplain take?

The first hearing often comes within weeks, and the NGT commonly appoints a joint committee to inspect and report. Final orders can take several months depending on the report and objections. Urgent interim directions, such as stopping dumping, can be given early if the evidence is clear.

How do I know whether a coastal plot falls in the CRZ?

Check the approved coastal zone management plan map for that area, which shows the high tide line and the zones, and ask for a site-specific map from an authorised survey agency if the plot is close to a boundary. The state CZMA can also confirm the status on application.

Can a building with local body approval still be demolished for CRZ violation?

Yes. A municipal sanction does not cure the absence of CRZ clearance where it was required, and courts have ordered demolition of occupied buildings on that ground. Buyers in such cases usually have to pursue the builder for refund and compensation.
