The residential high-rise project “Brigade Morgan Heights” in Perumbakkam, developed by Brigade Enterprises Limited, has received both Environmental Clearance (EC) and TN RERA registration. However, its proximity to the Pallikaranai Ramsar site has brought the approvals under renewed regulatory attention — especially after the Chennai Metropolitan Development Authority (CMDA) issued new instructions restricting permissions within the wetland boundary and its 1-km influence zone.
No approvals or permissions should be granted inside the Pallikaranai Ramsar site and its 1-km influence area until further notice.
This instruction was triggered by National Green Tribunal (NGT) directives to protect remnant marshland.
✅ Meaning: Even if a project already has EC and RERA, construction-stage planning permissions can still be paused or further scrutinized if the site lies within the restricted zone.
Survey parcels of Brigade Morgan Heights fall within Ramsar-notified boundaries despite environmental sensitivity.
Other media reports note hundreds of survey numbers overlapping Pallikaranai have been detected for compliance review.
📌 Key takeaway: Buyers must verify whether their specific tower footprint falls inside the red zone (Ramsar) or yellow zone (1-km buffer) as per the official CMDA map.
✅ 4) Buyer Obligations — What Booked Buyers Must Verify
3️⃣ Request written confirmation of building permissions issued:
Before Oct 2025? ✅
After Oct 2025? ❌ At risk without clarification
4️⃣ Verify wetland-impact compliance evidence is included in drawings and approvals
✅ 5) Guidance for Buyers Planning to Book
Do not rely only on brochures or model approvals.
Ask:
✅ “Is my specific tower cleared after the Ramsar directive?” ✅ “Does the sanction reference the updated CMDA Ramsar map?” ✅ “Can I receive planning authority confirmation in writing?”

🚨 7) What This Means in Practice
Environmental Clearance + RERA ≠ Guaranteed No-Risk Construction
Because the site’s parcel cluster intersects the suspicion zone, further approvals may require stricter environmental vetting or revised mapping.
Buyers must assess execution risk, not just approval status.
✅ Immediate Advisory for Buyers (Public Interest)
Based on the CMDA Ramsar boundary map, the survey parcel cluster for “Brigade Morgan Heights” appears to fall within the protected boundary and/or the 1-km influence area.
Until written clarification is provided by the competent authority on the exact tower footprints:
✅ New Buyers
➡️ Pause booking decisions
✅ Existing Buyers
➡️ Do not release further payments linked to construction milestones ➡️ Proceed only after receiving official written confirmation that your exact tower/tier is clear from restrictions
