MUMBAI, April 19 -- The state government has taken the first step towards setting up the Raigad-Pen Growth Centre, one of many growth hubs in Third Mumbai, the ambitious planned city being developed near the Navi Mumbai International Airport. A shareholder agreement was signed between the Mumbai Metropolitan Region Development Authority (MMRDA) and the Raigad-Pen Growth Centre Ltd in the presence of chief minister Devendra Fadnavis on Friday. It paves the way for developing a world-class smart city 25km from Panvel and 30km from the Navi Mumbai airport. MMRDA has written to the additional chief secretary of the state revenue department, requesting a stamp duty waiver on land deals to register the designated area as 'Raigad Pen Growth Centre'. The Raigad-Pen Growth Centre will be a business district developed on the lines of the BKC. It is envisioned as a major economic hub in the MMR, boosting economic growth, and attracting foreign investment. Spead across 1,217 acres, the smart city will involve land acquisition in 16 villages in Pen taluka, in Raigad district. MMRDA will oversee the project, which will be developed by M/s Orange Smart City Infrastructure Private Ltd (OSCIPL)....
