Amidst fleetly declining air quality - green spaces in Mumbai. The BMC is planning to construct underground parking lots under decades old public premises in Juhu and Bandra. Creating concrete crossbeams for these parking lots would bear century old rain trees to be cut. This would significantly impact seasonal flooding and the formerly rising temperatures that our megacity is floundering to manage with. The BMC has planned to push for underground parking installations under the decades old public premises videlicet famous Pushpa Narsee Park in Juhu and Patwardhan Park in Bandra. This is being done under a current provision in the megacity’s Development Control Regulations. The premises are the many remaining open spaces in Mumbai which has one of the poorest open spaces per capita rates anywhere in the world. These premises serve a multitude of functions they act as large bloodsuckers for rainwater amidst adding impervious and concrete developments thereby mollifying farther flooding pitfalls, they help reduce the CO2 in the air amidst the fleetly declining air quality and they help alleviate the compounding civic heat islet goods thereby forming an oasis for people in thick neighbourhoods. Creating an impervious concrete arbor for an underground parking lot would bear the century old rain trees to be cut and compromises the demesne’s capability to perform any of the below functions- thereby rendering it useless. These proffers will pave the way for analogous developments under all the premises in our megacity which would be disastrous to say the least. We need to act NOW to STOP it.
