Mumbai Flood & Climate Risk — Project Risk Map 2026
Mumbai's coastal geography means virtually all new residential inventory carries some flood or tidal risk. This page maps Brickplot's verified flood risk classification across Mumbai's scored project catalogue.

Frequently Asked Questions — Mumbai Flood Risk
Which localities in Mumbai have the highest flood risk?
Brickplot's current Mumbai 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 Mumbai projects are in CWC Category-A zones?
0% (0 of 90) scored Mumbai 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.
