Bangalore Flood & Climate Risk — Project Risk Map 2026

Bangalore's rapid urban expansion has put hundreds of residential projects inside documented flood hotspots — particularly around Bellandur, Varthur, HSR, Koramangala, Whitefield, and Sarjapur Road. Bangalore does not flood from a river: it floods from lake-catchment overflow and storm-drain (rajakaluve) failure. This page maps Brickplot's verified flood-hotspot classification across every scored Bangalore project.

Flood risk context: BBMP's vulnerable stormwater-drain and flood-prone-area records identify the hotspot belt across the city's south-east corridor. A project inside a documented hotspot scores lower on Brickplot's Location & Climate axis and cannot carry a Buy verdict, unless engineered mitigation is documented. Classification is geo-derived: each project's coordinates are measured against the hotspot set, not assigned by locality name.

Frequently Asked Questions — Bangalore Flood Risk

Which localities in Bangalore have the highest flood risk?

Bangalore, Sarjapur Road, Sarjapur, Hebbal, KR Puram contain the most projects sitting inside a documented flood hotspot, based on Brickplot's verified dataset. Projects there cannot carry a Buy verdict unless engineered mitigation is documented.

What counts as a flood hotspot?

A flood hotspot is a location a municipal authority has itself recorded as flood-prone — for Bangalore, BBMP’s vulnerable stormwater-drain and flood-prone-area records; elsewhere the equivalent city or state flood-hazard mapping. Brickplot measures each project’s coordinates against that hotspot set rather than judging by locality name. We deliberately do not call these “CWC Category-A” zones: CWC Category-A is a major-river flood-forecast class, and cities that flood from lake-catchment overflow and storm-drain failure — Bangalore chief among them — do not carry a CWC river category at all.

How does Brickplot factor flood risk into project scores?

Flood classification feeds directly into Axis 6 (Location, Infrastructure & Climate Risk, weight 14). A project inside a documented flood hotspot scores lower on that axis and cannot carry a Buy verdict, whatever its total — unless the builder has documented engineered mitigation (stormwater-drain upgrades, raised plinth, rainwater harvesting). The score cap that applied until 10 August 2026 was retired. The Buy suppression is applied mechanically with no editorial override.

What share of Bangalore projects sit inside a documented flood hotspot?

6% (64 of 1094) scored Bangalore residential projects sit inside a documented flood hotspot in Brickplot's verified dataset. The majority of scored projects are in low-risk or safe zones.
