Need Advice - Bengaluru

Was looking for a flat for investment purpose and came across some Flat which is 5 years old located in Gunjur. Price seems to be fair for a 3bhk and I'm contemplating whether to buy or not mainly due the bad road stretch from Panathur to Kadubesanahalli, is it okay to buy or would this be risky since it is flood prone area especially Bellandur Road Railway underpass bridge.

Please Advice
