The Chennai Metropolitan Development Authority (CMDA) is nearing the final stages of its ambitious Urban Wetland Park project in Porur, set to transform 16.63 acres of open space reservation (OSR) land adjacent to Sri Ramachandra University.
Pioneering in its approach, the park aims not only to enhance recreational amenities but also to serve as a crucial mechanism for flood mitigation and groundwater recharge within the urban landscape. With an investment of ₹12.60 crores, the Porur Urban Wetland Park is strategically designed on the sponge park concept, prioritising climate resilience by enabling the absorption and filtration of up to 90% of rainwater. This innovative approach diverges from traditional stormwater drainage systems, promoting sustainable water management practices essential for curbing urban flooding and preserving water resources.
CMDA officials highlight that the park’s infrastructure will include a 600-meter boardwalk, play courts, children’s play areas, seating zones, an outdoor gym, and an entrance gallery aimed at educating visitors about the significance of wetlands. Emphasising minimal environmental impact, the park integrates low-impact structures like boardwalks to ensure the preservation of natural hydro-ecological flows. Moreover, the Porur project underscores CMDA’s broader commitment to urban sustainability with plans for similar sponge parks in locations such as Kilambakkam. Additionally, the authority is actively pursuing the development of multiple parks and lakefront projects across Chennai, all aligned with the sponge city concept that minimises concrete usage, as announced via CMDA’s social media platforms.
Expected to become a sanctuary for over 85 species of native flora and fauna, the Urban Wetland Park not only enriches the local ecosystem but also serves as an invaluable educational resource on wetland conservation. As the project nears completion, stakeholders anticipate its role in redefining Chennai’s environmental landscape, setting a benchmark for future urban green initiatives.
