The already reducing cover of mangroves in Navi Mumbai is set to be chopped further, with a proposal being submitted by CIDCO to the ministry of environment, forest and climate change, seeking to take mangrove area equivalent to approximately 16 football fields for setting up extra high voltage transmission (EHVT) Lines. Presently, the EHVT Lines are passing through the proposed area for the Navi Mumbai International Airport (NMIA) as well as the approach funnel of the airport. They will have to be shifted to facilitate the construction of NMIA, and make the airport operationally safe.

CIDCO has already submitted the proposal regarding the shifting of EHVT lines to the central government. The linear portion of 9.0361 hectare of forest land has been proposed for the diversion. Some 24.01 hectare of non-forest land is required for the R823.45 crore project. The portion of the land required for the project also includes areas around 10 villages in Raigad district and the forest patch that will be diverted will be from Sonkhar, Ulwa, Targhar, Vaghivli, Panvel, Kamothe, Kharghar.
