The proposed facility footprint removes park land. The map highlights the footprint and labels the exact area.
“Before vs after” view: existing park space versus the proposed footprint. This step adds a shaded “impact zone” and focuses your eye on the change.
The site sits near flood risk features. This step overlays a floodplain proxy layer and adds on-map annotation callouts. Replace the proxy with authoritative flood data (FEMA NFHL export or local floodplain GIS).
A “You Draw It”-style interaction: drag your guess for per-bed cost, then reveal benchmarks.
Update values in data/metrics.json.
This step switches to a set of alternative sites / scenarios. You can add “vertical expansion,” “satellite model,” and “non-park parcels” as additional layers with pros/cons cards.
This step overlays a simple access proxy and opens the “distributional impact” card. Replace proxy with network-based isochrones when ready (OpenRouteService, Valhalla, or Mapbox).
