The Brihanmumbai Municipal Corporation (BMC) has made the plantation of green spaces using the Miyawaki method mandatory at construction sites that are more than 10,000 sq m in area.

Municipal Commissioner I S Chahal took a decision in this regard on Monday. The building proposal department will now include this condition in its intimation for disapproval (IOD), a letter that the civic body sends to a builder or developer who proposes to undertake construction work.
