LGU Planning Center · CDRA
Understand your LGU's hazards, exposure, vulnerability, and risk — and turn the findings into land use decisions that hold up.
Hazards → Exposure → Vulnerability → Risk → Priority Areas → Interventions. Select a stage to see what it needs and what it produces.
Step 1
Identify and characterize the hazards that affect the LGU.
Compile hazard maps and characterize each hazard by frequency, magnitude, extent, and duration — floods, rain-induced landslides, storm surge, earthquake, liquefaction, ground shaking, tsunami, volcanic hazards, drought, and sea level rise.
Enter a location and instantly generate a report on seismic, volcanic and hydrometeorological hazard exposure — the fastest starting point for hazard characterization.

Your exposure database is only as good as the data behind it. Here is what to collect for each category.
People living in hazard-prone areas, disaggregated enough to show who is most at risk.
Built-up areas and the economic activity that happens in them.
Farms, fisheries, forests, and other production areas that livelihoods depend on.
Facilities that must keep working during and after a disaster.
The networks that keep water, power, and communication flowing.
The foundational guidance linking the CDRA to the CLUP — what the assessment must produce and how those outputs change land use decisions.
