City and Industrial Development Corporation (CIDCO), is planning to build the Navi Mumbai Airport Influence Notified Area or Naina, the first planned township of Mumbai.

Naina, the new planned city, expected to be spread over 600 sq km or 60,000 ha can house a population of approximately 80 lakh in the next 30 years.

CIDCO has not yet revealed the estimated cost of developing this new city. The project will include development of metro line and roads etc, and will be spread around a radial distance of about 25 km from the proposed airport in Navi Mumbai.

The corporation is looking forward to developing the new township in two phases. In Phase-I, about 7,000 ha will be taken up for development for which a detailed plan is being prepared. For the development of Phase-II, around 53,000 ha will be taken up after five years.

CIDCO has invited tenders for the survey of the city, which will take five to six months to complete.

At present, the proposed city of Naina has 270 villages in the six talukas of Thane, Uran, Karjat, Pen, Khalapur and Panvel of the Thane and Raigad districts.

Further, the project will not involve any acquisition of land. People will be invited to give their lands for the development of the city in return for which CIDCO will offer them some incentives.
