Hoodi monsoon drainage: last year's rains were a shocker

₹1.5 crore for a 3BHK near Hoodi sounds decent, but last monsoon ka scene dekh ke I'm worried. Pichle saal, kafi areas mein knee-deep water tha, especially Venkateshpura ke paas. Builder bolte hain drainage achha hai, par ground reality kuch aur lagti hai. Kya residents ko really issue hua tha? Is it a yearly problem or was it just ek-do baar? Long-term living ke liye ye kitna bada concern hai? Any experience from current residents?
