BANGALORE: More than 590 houses in JP Nagar VII phase have been identified for demolition by the Bangalore Development Authority (BDA) to make way for storm water drains and wider roads. It is to prevent flooding of areas like Puttenahalli and Dollar Layout. According to a recently completed BDA survey, the demolition of the houses on 17th Cross will allow construction of a 15-foot-wide and 2.2-kmlong storm water drain, connecting Jaraganahalli tank to the drain flowing through Dollar Layout.
Jaraganahalli-Sarakki tank and the Puttenahalli tank, spread over 32 hectares, have the maximum catchment area in the city and also receive overflowing waters from Kothanur and Chunchungatta tanks. Water flowing into the Dollar Layout drain, starting from Jayanagar till Bannerghatta and further to Agara, Bellandur and Varthur tanks, floods areas alongside these tanks. "This storm water drain, from north to east, connects lakes like Puttenahalli, Madiwala, Agara, Bellandur and Varthur. The excess water will flow through this drain, preventing the areas situated along the catchment getting flooded.The widening of roads in JP Nagar area from 20 metres to 45 metres will help us construct this drain," BDA engineers said. Demolition of buildings is also slated for areas closer to Chunchungatta tank and Kothanur tank. "Demolition has to be sanctioned by the deputy commissioner (Bangalore Urban). It will be taken up after giving residents a prior notice and due compensation," another official said.
