Lal Bahadur Shastri International Airport (LBSI) at Babatpur is going through the biggest expansion in its history, and that changes the height-clearance picture for everyone building nearby. The runway is being extended from 2,745 m to 4,075 m, and the terminal is growing to handle nearly 10 million passengers a year, up from under 4 million today. A bigger runway and a busier flight path both affect how AAI evaluates height near the airport.
This page covers what an Airport NOC survey Varanasi project needs to account for. That includes the airport’s regulated radius, why the ongoing expansion matters for anyone applying right now, and how the survey and NOCAS process actually work for this specific airport.
Why Varanasi’s Airport Expansion Matters for Your NOC
LBSI sits at Babatpur in Pindra Tehsil, roughly 26 km from the city center, at a surveyed elevation of about 82 metres AMSL. Under normal circumstances, that elevation feeds directly into AAI’s height calculations for the surrounding zone.
However, the current expansion changes several inputs at once. The runway extension shifts the Aerodrome Reference Point calculations. The new terminal and taxi track add elevated structures of their own. A wider approach corridor for larger aircraft can also mean a revised Colour Coded Zoning Map once the expansion is complete.
For this reason, don’t assume that an older CCZM reading for your plot still holds. It’s worth checking the current zoning status directly before finalising any layout, especially if your site sits along the airport’s approach or departure path.
Varanasi’s Growth Is Pushing More Projects Into This Zone
Varanasi has grown rapidly as both a religious and tourism hub. LBSI now ranks among India’s busier airports by passenger movement, and its capacity is set to more than double once the current expansion finishes.
This growth brings more hotels, guest houses, commercial complexes, and residential towers into the airport’s regulated radius than in previous years. Many of these projects sit closer to the flight path than developers initially realise, simply because the city’s growth corridors overlap with the airport’s zoning.
If you’re planning a project anywhere between the city core and Babatpur, it’s worth checking your exact distance and bearing from the runway early. Waiting until after you’ve finalised a design risks discovering a height constraint only after significant planning work is already done.
How Long Does an Airport NOC Take in Varanasi?
Field survey work for a single plot near LBSI typically takes a few days. Certified documentation is usually ready within two to three weeks after that.
AAI’s own review time through NOCAS depends on case load and on whether your site needs closer scrutiny because of its position relative to the airport’s active expansion works. Projects along the extended runway’s new approach path may see additional review time until the updated zoning is formally in place.
Building buffer time into your project schedule is a sensible precaution here, especially while the airport’s own infrastructure is still under construction.
Do You Need an AAI NOC Near Babatpur?
LBSI operates as a standard civil airport under AAI, so the usual VFR airport rule applies here. Under Gazette Notification GSR 751(E), any structure within 20 km of the airport’s Aerodrome Reference Point needs to be checked against the applicable height restriction, regardless of the structure’s intended use.
Whether you need a full NOCAS application, though, depends on where your surveyed elevation falls relative to the permitted top elevation for your grid cell. If your proposed structure’s top elevation is below that threshold, AAI’s system can auto-settle the case without a full manual review. If it exceeds the threshold, you’ll need to file formally.
Which Areas Around Varanasi Fall Under This Requirement
The regulated radius extends well beyond the immediate airport perimeter. It covers Babatpur itself, along with Sarnath, Ramnagar, Varanasi Cantonment, and large parts of the city core closer to the Ganges, depending on exact distance and direction from the runway.
Sarnath deserves particular attention here. As one of Buddhism’s most significant heritage sites, development in this corridor already involves heritage and archaeological clearances. Adding an airport NOC requirement on top of that means checking multiple approval layers before construction can proceed, not just one.
Rooftop Additions Count Too
A common oversight near Varanasi’s growth corridors is treating the NOC requirement as something that only applies to the main structure. It doesn’t.
AAI’s height calculation includes rooftop water tanks, lift motor rooms, telecom masts, and lightning arresters, not just the building’s primary height. A project that clears comfortably on paper can still trigger a review once these additions are factored in.
This is especially relevant for hotels and guest houses near Babatpur and Sarnath, where rooftop water tanks and solar installations are common. Getting your full structure height, additions included, verified against the CCZM avoids a surprise later in the approval process.
How an Airport NOC Survey Works in Varanasi
- Zone and CCZM check — Confirm your plot’s distance and bearing from LBSI’s Aerodrome Reference Point, and check the current permitted top elevation for that specific grid cell, factoring in the airport’s ongoing expansion.
- Site elevation and coordinate survey — A site elevation survey captures WGS-84 coordinates and AMSL elevation for your plot, meeting AAI’s accuracy requirements.
- Height verification — We check your proposed structure’s top elevation, including any rooftop additions, against the CCZM’s permitted top elevation for that grid.
- Documentation — We compile certificates, ownership proof, and structure drawings per AAI’s NOCAS documentation requirements.
- NOCAS filing or auto-settlement — Depending on whether your structure exceeds the CCZM threshold, we either file formally through NOCAS or let the system auto-settle the case.
Which Projects in Varanasi Need This
This requirement isn’t limited to large commercial buildings. It applies to:
- Building height clearance for residential and commercial construction anywhere within the regulated radius, including Cantonment and the areas closer to the city core
- Hotels and hospitality projects, which have grown steadily around Varanasi given its position as a major pilgrimage and tourism destination
- Solar and wind or hybrid renewable installations planned in the outer growth corridors near Babatpur and Pindra
Why Get Your Varanasi Airport NOC Survey Done by Surveying India
Our in-house DGPS and Total Station teams deliver WGS-84 coordinates and AMSL elevation certified to AAI’s accuracy requirements across Varanasi, Babatpur, Sarnath, and Ramnagar. We track the airport’s ongoing expansion closely, so we flag any zoning changes that might affect your project before you commit to a layout.
Because we prepare documentation to AAI’s exact NOCAS format, we cut down the remarks and resubmissions that stall projects, especially in a period when the airport’s own infrastructure is actively changing. We also coordinate directly with heritage and municipal clearance processes where a site, like one near Sarnath, needs more than just an airport NOC.
Beyond Varanasi, we’ve delivered survey work for government bodies, PSUs, and private developers across airport-regulated zones in India for over a decade. Our teams also work in Pune, Mumbai, Bengaluru, Delhi NCR, Jaipur, Lucknow, Chandigarh, Ahmedabad, Kota, and Bhopal.

Frequently Asked Questions
Why does Varanasi airport’s expansion matter for my NOC application? The runway extension from 2,745 m to 4,075 m, along with the new terminal and taxi track, changes several inputs AAI uses for height calculations. An older CCZM reading for your plot may not reflect the airport’s current or planned configuration.
How far does the AAI NOC requirement extend from Babatpur? Under Gazette Notification GSR 751(E), the requirement to check applies to any structure within 20 km of the airport’s Aerodrome Reference Point, covering Babatpur, Sarnath, Ramnagar, Cantonment, and parts of the city core.
Is every construction project near LBSI required to file a full NOC application? Not necessarily. If your proposed structure’s top elevation stays below the CCZM’s permitted top elevation for your grid cell, AAI’s system can auto-settle the application without a full manual review.
Does a project near Sarnath need more than an airport NOC? Often, yes. Sarnath’s status as a major Buddhist heritage site typically involves separate heritage and archaeological clearances, in addition to any airport height clearance requirement.
What is LBSI’s surveyed elevation, and why does it matter? The airport sits at approximately 82 metres AMSL. This figure anchors AAI’s height calculations for the surrounding zone, which is why an accurate site elevation survey for your own plot matters just as much.
Where can I check the current CCZM for Varanasi? The current Colour Coded Zoning Map, where available, is published on AAI’s NOCAS portal. Given the airport’s ongoing expansion, it’s worth confirming the latest version before finalising a project.
Regulatory reference: Height clearance rules near Lal Bahadur Shastri International Airport fall under Gazette Notification GSR 751(E). Zoning data is maintained by the Airports Authority of India on the official AAI NOCAS portal. Always verify the current PTE and zone classification for your specific coordinates before finalising a project.
