Nautiyal, in an email letter to Prime Minister Narendra Modi, alleged that the state government had vested interests behind the proposal.
The email was also forwarded to Union Urban Development Minister M Venkaiah Naidu, Uttarakhand Governor K K Paul and Chief Minister Harish Rawat.
"The proposal from the state government which envisages building a smart city on a tea estate in Dehradun is wrapped in a web of blatant corruption and is completely anti-people and anti-environment," Nautiyal said.
