Haryana is set to dramatically shrink its footprint within the National Capital Region and Panipat, Karnal, Jind, Mahendragarh and parts of Bhiwani are staring at the sharpest consequences.According to the agenda circulated among participating states for the NCR Planning Board’s (NCRPB) upcoming meeting scheduled for June 16, the re-delineation of the NCR boundary remains a live agenda item, with the Draft Regional Plan-2041’s boundary principles set to be formally progressed.The Draft RP-2041, approved in principle at the NCRPB’s 41st Board Meeting on October 12, 2021, proposes limiting the NCR to a contiguous circular zone of 100 km radius from Rajghat, Delhi. Currently, Haryana contributes 14 districts to the NCR-Gurugram, Faridabad, Rohtak, Sonepat, Rewari, Jhajjar, Mewat, Palwal, Panipat, Mahendragarh, Jind, Karnal, Bhiwani and Charkhi Dadri-covering a combined area of 25,327 sq. km.Under the new boundary formula, that area would be slashed to just 10,546 sq. km– a reduction of nearly 60 per cent, as recorded in Chapter 1, Paragraph 1.7.1(viii)(b) of the plan document.What makes Haryana’s position particularly consequential is its self-imposed stricter stance. As recorded in Paragraph 1.7.1(viii)(a), while Uttar Pradesh and Rajasthan agreed to include tehsils even partially within the 100 km radius, “Haryana has conveyed its decision to keep only those tehsils within the NCR which are covered entirely within the 100 km radius.”Applying this rule to geography, the impact spreads across five to six districts. Karnal city sits approximately 113-121 km straight-line from Delhi-clearly beyond the arc–placing most of the district at risk.Mahendragarh is even farther at roughly 112–113 km, and with no significant portion of the district close to the boundary, it faces near-total exclusion. Jind city sits 103-115 km from Delhi, right on the margin, with tehsils almost certainly extending beyond it. Panipat city, at 88-95 km, is borderline-the city itself may survive but the wider district extends well past the 100 km mark. Bhiwani city is about 107-108 km away but lies due west of Delhi, meaning some of its closer tehsils may survive depending on the arc.Charkhi Dadri, at roughly 83 km straight-line, is the safest of the lot -its city sits within the radius, though some district tehsils could still be clipped. In total, the majority areas of at least five Haryana districts face exclusion from the NCR once the boundary is formally notified.Haryana has, however, built in buffers to soften the blow. The state has proposed a 1 km corridor on both sides of eleven National Highways, including NH-44, NH-48 and NH-9, for continued NCR inclusion. Karnal and Panipat, both sitting on NH-44, could see their urban cores retained through this highway corridor provision. Bhiwani has a partial lifeline via NH-148B and Charkhi Dadri via NH-334B, both on Haryana’s named list. Jind and Mahendragarh, notably, do not sit on any of the 11 named highways, giving them no corridor-based safety net whatsoever.Critically however, the draft plan document does not name the specific municipal bodies Haryana wants retained. It only states the numbers , 26 Municipal Committees, 13 Municipal Councils and 7 Municipal Corporations, noting these were “conveyed” by Haryana to NCRPB as a separate state-level communication not publicly available.Haryana currently has 9 Municipal Corporations in total. Of these, Gurugram, Faridabad, Manesar and Sonipat sit firmly within the 100 km radius. Panipat Municipal Corporation, given its position on NH-44, is likely on the retained list. Karnal and Rohtak, both on major highways and near the radius, round out the probable seven. But this remains unconfirmed, no annexure in the publicly available draft plan carries the named list, and an RTI with NCRPB would be needed to establish it definitively.On the ground, exclusion from the NCR carries real costs. Towns outside the boundary lose access to NCRPB’s infrastructure financing pipeline, which has funded 366 projects worth over Rs 32,000 crore across the region. Land use and development norms would revert entirely to Haryana’s Town and Country Planning rules, removing the overriding authority of the NCRPB Act.The proposed 30-minute rail connectivity network, RRTS corridors and orbital rail planning under RP-2041 are designed only for areas within the NCR boundary.In property markets, loss of NCR status historically triggers land repricing, a pullback by institutional investors and a slowdown in large-format project approvals. For districts like Karnal, Jind and Mahendragarh, where NCR-linked land value premiums have shaped real estate and industrial investment decisions since 2015, when they were added to the region, the reversal would be particularly jarring.
