The Greater Chennai Corporation has sought the assistance of Anna University to come up with a road design for 'smart' T Nagar that will prevent on-street flooding during rain.
TOI had earlier reported that the local body would borrow flood damage assessment technology developed by the Institute of Remote Sensing (IRS), Anna University. The corporation has now asked the IRS to help fix the road camber in T Nagar in accordance with the mean sea level, an informed source said.
Deputy commissioner (works) K S Kandasamy met IRS faculty members on the university premises earlier this month to discuss the feasibility of the project, the source added. The corporation will execute the project under the Smart City component for T Nagar.
Poor road design is cited as one of the reasons for water stagnation when it rains. Storm water drains fail to collect runoff water due to faulty design of roads, including disproportionate road camber and the varying height between the road surface and chute pipe mouths of drains.
In this project, the corporation will attempt to fix the gradient of all major roads in T Nagar uniformly. "When the road camber is adjusted to the mean sea level, it will help rainwater runoff," said D Thirumalaivasan, director, Centre for Disaster Mitigation and Management, IRS. The institute will use GPS technology to fix the camber height, he added.
Kandasamy told TOI that making the road level proportionate to the mean sea level means the corporation can check the road height during re-laying. "It will prevent the road height increasing. With a fixed camber and height, the contractors will have a marker to measure against," he said. To this end, the corporation will lay stones, similar to the milestones found on national highways, at the points that will be marked by the IRS faculty.
A consent letter has been received by the corporation. Dependent upon costs being agreed between both parties, the IRS is expected to begin work on the project by early next year.
