Bangalore Flood & Climate Risk — Project Risk Map 2026
Bangalore's rapid urban expansion has put hundreds of residential projects in CWC-classified flood zones — particularly around Bellandur, HSR, Whitefield, and Sarjapur Road. This page maps Brickplot's verified flood risk classification across every scored Bangalore project.

Frequently Asked Questions — Bangalore Flood Risk
Which localities in Bangalore have the highest flood risk?
Brickplot's current Bangalore dataset shows limited CWC Category-A designations. Most projects are in low or safe zones.
What is CWC Category-A flood zone?
CWC Category-A is the highest tier in the Central Water Commission flood-risk classification — localities with documented severe waterlogging, lake-catchment overflow, or recurring monsoon flooding. Brickplot applies a hard score cap of 5.4 on the Location & Infrastructure axis for Cat-A projects unless the builder has documented engineered mitigation in RERA Form A.
How does Brickplot factor flood risk into project scores?
Flood zone classification feeds directly into Axis 6 (Location, Infrastructure & Climate Risk, weight 14). A CWC Category-A designation triggers a hard score cap of 5.4 — the overall project score cannot exceed 5.4 regardless of other axis performance — unless the builder has documented engineered mitigation (SWD upgrades, raised plinth, RWH). This cap is applied mechanically with no editorial override.
What percentage of Bangalore projects are in CWC Category-A zones?
0% (0 of 1056) scored Bangalore residential projects are classified as CWC Category-A flood risk in Brickplot's verified dataset. The majority of scored projects are in safe or low-risk zones.
