In Bangalore , the extent of lake buffer zone is 30 metres around the water body. Before you buy a property situated near a water body, ensure that it does not come under the buffer zone!
Secondly, make sure the property you are planning to buy is not within 25 metres around the Rajakaluve or a stormwater drain. Rajakaluves are pathways that are responsible for transferring excess water into a water body, especially during excessive rains or floods. Any clogging of the stormwater drains leads to serious problems in the city's drainage system. Construction activity of any kind within the 25 metre range of Rajakaluve is strictly prohibited.
