Puzhithivakkam lake, also called Sitheri, stretches from Balaiah Garden on the Madipakkam side to behind a government school campus on the Puzhithivakkam side. Residents say garbage is being dumped in the lake and accumulating along the bund, while broken footpath sections inconvenience walkers. Most of the walkway has an iron fence and bollards to deter unauthorised entry by people and vehicles.

Seeni Sethuraman, an office-bearer of the Water Bodies Rejuvenation Form Trust and a Madipakkam resident, said the lake had become a popular spot for walkers but its facilities were poorly maintained. He alleged that the Greater Chennai Corporation (GCC) and Water Resources Department (WRD) do not clean the lake regularly. A senior GCC official for the Sholinganallur zone said the lake belongs to the WRD, but the civic body regularly cleans the walkway with conservancy staff.

• The final 3.5-km MRTS stretch between Velachery and St Thomas Mount opened to passengers on Saturday, completing the 23-km Chennai Beach–St Thomas Mount corridor, built at a total cost of ₹1,924 crore. First trains departed both ends at 5 a.m.
• The extension is expected to improve access to commercial hubs for commuters from Nanganallur, Puzhuthivakkam and Adambakkam. It includes two intermediate stations, Puzhuthivakkam and Adambakkam; St Thomas Mount is the terminal and an integrated hub linking MRTS, Chennai Metro and suburban rail.
• Work began in April 2008. Land acquisition disputes over the final 500 metres, involving about 75 houses in Adambakkam and Thillai Ganga Nagar, delayed the project nearly 15 years. Owners challenged compensation under the Land Acquisition Act, 1894, seeking compensation under the 2013 land acquisition law. The Madras High Court dismissed 40 petitions in 2019.
• In August 2025, the Ministry of Railways approved transferring MRTS operations to CMRL, a proposal initiated by Tamil Nadu in 2011.

Flood-prone areas and main roads in Velachery, Madipakkam, Puzhuthivakkam, Adambakkam, Adyar and Thiruvanmiyur were largely free of water stagnation after up to 12cm of rain in the 24 hours ending Tuesday morning. The Regional Meteorological Centre issued a red alert for Chennai on Tuesday, but southern areas received less intense rain than the north.

At Taramani, MGR Main Road had water stagnation, while Periyar Nagar and Bharathi Nagar did not. Velachery’s Vijaya Nagar bus terminus was clear, with only a few puddles reported. Interior roads in Ram Nagar and Rajalakshmi Nagar were largely free of inundation. In Madipakkam, Eswaran Koil Street, Jeeva Nagar and Rajarajaeshwari Nagar had minor inundation at road edges. Interior roads on OMR faced waterlogging.

A 200-metre road serving Subramania Nagar and Dharma Nagar in Puzhudhivakkam has not received a new surface since 2007. Civic officials said Subramania Nagar does not appear in official records, leaving the neighbouring Dharma Nagar road unrepaired; it was last relaid in 2013. The areas came under Chennai Corporation limits in 2011. Residents face potholes and slush.
