The Noida administration, Yamuna International Airport Private Limited and Noida International Airport Limited will begin the survey soon.
Officials said the final survey was needed before the construction of the boundary wall because the fencing done last year differed slightly from the map approved for the project.
Spread over 1,334 hectares, the periphery of the airport was demarcated through May and June last year.
However, while putting up the barbed wire, the officials had left out a portion of agricultural fields that were still being tilled at that time. Similarly, a majority of the borewells, nullahs and drainage channels were also kept out of the periphery.
“The idea was to demarcate the land before a permanent boundary wall was erected and allow the villagers to reap the harvest. But now, it is time to construct the wall. A final survey is underway and representatives of all three stakeholders will approve it jointly,” said Balram Singh, ADM (land acquisition).
As part of the survey, officials from the revenue department, including patwaris and tehsildars, will go around the villages with maps in hand and mark out the portion that has to be included or excluded before the construction of the wall begins. Sources said 109 of more than 4,000 land chunks would need to be revisited.
