Hazard check

Is public money going where the hazards are?

Search a province, city, town or barangay, or a DPWH project name or contract ID. You’ll see how its projects sit on official flood, landslide, storm-surge and active-fault maps, next to what was spent.

Hazard vs. spending

Hazard	Projects in med/high zone	Spending in med/high zone
Within 5 km of active fault	0 of 332 mapped	— (0%)
Flood (100-year)	53 of 332 mapped	₱1.8B (26%)
Landslide	9 of 332 mapped	₱325.4M (5%)
Storm surge	18 of 332 mapped	₱161.7M (2%)

High shares can be expected (flood-control works belong in flood zones) or worth a closer look (schools, buildings).
