Demo workspace
A fictional coastal-to-upland municipality used to demonstrate how a Climate and Disaster Risk Assessment is assembled, visualised, and carried into a Comprehensive Land Use Plan.
Every figure, boundary, and risk score on this page is invented for teaching purposes. The Municipality of Bayanihan does not exist, and none of these numbers describe any real Philippine locality. The base map is real OpenStreetMap tiling, but the demo boundaries drawn on top of it are not real barangay boundaries and their position is arbitrary — they say nothing about the actual places underneath.
Toggle layers, choose a hazard, and click a barangay to open its assessment.
The base map stays on. Overall risk takes precedence over hazard shading when both are selected.
River overflow and rainfall ponding along the demo floodplain. In a real CDRA this layer comes from an agency-issued flood susceptibility map plus local flood-mark validation.
| Exposure sector | Hazard | Risk class | Basis |
|---|---|---|---|
| Population | Storm surge | Very High | Demo households within 100 m of the shoreline. |
| Urban Use Areas | Storm surge | Very High | Fish landing and adjacent housing. |
| Critical Point Facilities | Storm surge | High | Elementary school used as evacuation centre is itself exposed. |
| Lifeline Utilities | Flooding | High | Coastal road overtopped in the demo scenario. |
Bars are coloured by the barangay's overall demo risk class.
Step 5 of the assessment. Each finding ends with one of the four risk management options.
Baybay
Demo households and the fish landing sit inside the highest surge advisory zone, and the designated evacuation centre is itself exposed.
Planned response: Designate the shoreline strip as a no-build buffer in the demo CLUP, identify an inland relocation receiving area, and re-site the evacuation centre.
Mapagmahal, Bundok
Demo settlements sit on slopes above 30 percent with a single access road crossing an unstable cut.
Planned response: Slope protection on the access road, early-warning rain gauges, and a managed phase-out of new residential permits in the steepest demo blocks.
Poblacion, San Roque
The demo market and municipal offices flood in the modelled event, interrupting services and trade.
Planned response: Drainage upgrade, elevated ground floors for new permits, and continuity arrangements for demo municipal services.
Malinao, Masagana, Katipunan, Bagong Silang
Demo ricefields and ponds flood in the wet season while rainfed farmland loses yield in dry spells.
Planned response: Enrol demo farmers and fisherfolk in crop and fisheries insurance, paired with water-impounding and drought-tolerant varieties.
Bagong Silang, Baybay
A high share of demo dwellings use light materials and lose roofing in severe wind.
Planned response: Housing retrofit assistance and enforcement of demo building standards on roof fastening.
Katipunan, Bagong Silang
Demo Level I and II water systems fall short during extended dry spells.
Planned response: Monitor demo yields and keep a water-hauling contingency while a longer-term source study is programmed.
What the assessment hands to the plan: a prioritised list of interventions with a timeframe and a lead office. Downloadable report generation is on the roadmap below.

| Barangay CDRA orientation and data-collection training | Capacity | Dry-spell stress on small water systems | Short (1–3 yrs) | MPDO (demo) |
Costs are deliberately left uncosted — a real investment programme prices each item against actual unit costs and available funds.

This demo is read-only. These capabilities would turn it into a tool an LGU could run its own assessment in.
LGU accounts and workspaces
Each LGU gets a private workspace with its own users and permissions.
GIS data upload
Upload shapefiles and GeoJSON boundaries to replace demo geometry.
Barangay data collection forms
Structured forms so barangays can submit exposure data directly.
Hazard layer upload
Bring in agency-issued hazard maps and overlay them on your own boundaries.
Exposure database builder
Guided entry for population, facilities, lifelines, and natural resources.
Collaborative review
Comment, flag, and sign off on risk findings across departments.
Automated risk calculations
Compute vulnerability and risk scores from uploaded exposure and hazard data.
Scenario modelling
