Avadi

Avadi is a city situated within the Thiruvallur district of Tamil Nadu, India, operating inside the Chennai metropolitan area. As part of the Thiruvallur district, the locality functions as the headquarters for the Avadi City Police, Avadi City Corporation, and Avadi Taluk, positioned approximately 22 kilometres from Chennai Central Railway Station.

Terrain and Expanse The urban settlement spans a total area of 65 square kilometres, which translates to 25 square miles. Ground topography sits at an average elevation of 17 metres, equivalent to 56 feet above sea level, positioned precisely at coordinates 13.12°N and 80.1°E. The sprawling municipal landscape stretches directly from Poonamalle High Road across to MTH Road.

Waterscapes and Habitat The geographical footprint features Paruthipattu Lake, a historic body of water stretching 2.64 kilometres in length and covering 200 acres behind Thirumullaivoyal and the Tamil Nadu Housing Board. Formerly known historically as Paaleripattu in ancient land documents, the aquatic expanse historically provided critical irrigation for nearby farmlands and continues to attract numerous birds throughout the year. Though decades of urbanization brought encroachment and sewage pollution, the lake zone was transformed into an eco-park featuring a 3-kilometre-long walking track, a central plaza, and renewed greenery following a renovation budget of 32 crores.

Demographic Landscape By the 2011 census, the city recorded a permanent population of 345,996 residents, securing its place as the 10th most populous area across Tamil Nadu. Households numbered 87,733 within the 65-square-kilometre territory, supporting a local population density shaped by decades of industrial expansion since the post-World War II era, supported further by the Avadi Railway Station of the Chennai Suburban Railway.
