AAP workers also held a demonstration at the proposed site yesterday to protest the state government's move.
Leading the protest demonstration, AAP leader Anoop Nautiyal alleged that the state government's decision was aimed at helping corporate giants.
Nautiyal claimed he has written to Prime Minister Narendra Modi urging him to reject the state's smart city proposal.
The proposed Smart City project on the tea estate land has already drawn opposition from the BJP and environmentalists besides the locals and plantation workers.
However, Rawat had assured welfare of the workers and residents of the area would be ensured and a major part of the proposed Smart City will be left as 'green cover'.
