Significance of the Region:

1. Wetlands with remediation functional ability (function as kidneys of the landscape). Removal of wetlands will affect the functional ability of the lake and would result in the death of Bellandur lake;
2. Considering severe water shortage to meet the drinking water requirement in Bangalore, there is a need to remove deposited silt in the Bellandur lake, which will enhance the storage capacity and in turn helps in mitigating the water requirement;
3. Wetlands aid in recharging groundwater as soil are permeable;
4. Belanduru lake provide food (fish, etc.) and fodder;
5. Retain the excess water and prevent flooding in the vicinity;
6. Large number of farmers in the downstream is dependent on Belanduru lake water for agriculture, vegetable, etc.

Realizing these, BDA has aptly earmarked these regions in CDP 2005 for “ENVIRONMENT PROTECTION AND HERITAGE CONSERVATION”. The masterplan includes the protection of valleys and tanks as part of the vision and enforcing the ban on construction over protected areas. CDP 2015: As per CDP 2015, valley region are “No Development Zone”

1. In case of water bodies a 30.0 m buffer of ‘no development zone’ is to be maintained around the lake (as per revenue records) with exception of activities associated with lake and this buffer may be taken into account for reservation of park while sanctioning plans.
2. If the valley portion is a part of the layout/ development plan, then that part of the valley zone could be taken into account for reservation of parks and open spaces both in development plan and under subdivision regulations subject to fulfilling section 17 of KTCP Act, 1961 and sec 32 of BDA Act, 1976.
3. Rajakaluve/ storm water drains categorized into 3 types namely primary, secondary and tertiary.These drains will have a buffer of 50, 25 and 15m (measured from the centre of the drain) respectively on either side. No activities shall be permitted in the buffer zone.
