In order to develop the twin cities including Ajmer and Kota in Rajasthan as the world class urban hubs, the state government has chalked out an ambitious plan to invest a staggering sum worth Rs. 2,808-cr on the planned projects. As per the original roadmap, Ajmer will be developed on retrofitting model, while Kota will get the newest touch on the green-field model for which there will be three approaches - retrofitting, redevelopment and green-field development. Under the retrofitting scheme, a city can undertake an area of minimum 500 acres and implement the scheme in three years and in the case of green-field development, the project area can be a vacant land spread over at least 250 acres and the project can be completed in phases. For Ajmer, the state has proposed to develop 1,334-acre area, out of which Rs 925-cr has been earmarked for area-based development and Rs 341-cr for pan-city upgrade. The major development has been proposed in the north side of Anna Sagar Lake in Ajmer. Similarly, for Kota which is to be developed as a green city, the state has proposed 395 acre area adjoining to Indian Institute of Technology (IIT) near Ranpur Village on which Rs 1,045-cr will be spent to develop the area and Rs 437-cr for the pan city development.
