Hazard vs. spending in San Lorenzo Ruiz

Shown for the parent city/municipality: hazard totals are computed at city/municipality level, not per barangay.

Hazard	Projects in med/high zone	Spending in med/high zone
Within 5 km of active fault	0 of 72 mapped	— (0%)
Flood (100-year)	14 of 72 mapped	₱420.9M (28%)
Landslide	9 of 72 mapped	₱78.9M (5%)
Storm surge	0 of 72 mapped	— (0%)

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