Risk assessment
Scores, and the working behind them
Exposure, sensitivity, adaptive capacity, likelihood — every column a reviewer checksEvery intermediate score, not just the total. A DHSUD reviewer checks the columns, and an assessment that cannot show its working gets sent back.
How exposure is estimated. Population and land-use exposure apply the barangay's susceptible AREA share to its population and its built-up area, because no source publishes where within a barangay people live. That is the standard simplification and the published CDRA makes it too, but it is an assumption rather than a measurement. Critical-facility exposure is the exception: those have coordinates, so it is a real point-in-polygon test.
Very High — ProhibitedHigh — DiscretionaryModerate — ConditionalLow — PermittedNot scored
The highest risk category reached in each barangay, per hazard.
Each barangay is shaded by the highest risk category found in it — not an average. A barangay with one exposure unit at very high risk is a very-high-risk barangay for planning purposes, and averaging that down would hide exactly what a land-use control exists to address.

Critical facilities
The one exposure unit that is measured rather than estimated: each facility has coordinates, so this is a point-in-polygon test against the agency's own hazard geometry. A facility is either in the hazard zone or it is not — DHSUD scores that 4 or 1, with nothing in between.
