KubangPawis/project-sbafn ? reverse-engineered prompt

Build me a web app for Project SBAFN that shows flood risk at the street level for Philippine cities, not just broad area zones. I want an interactive map where each road segment is color coded so people can quickly see which streets are low, medium, or high risk, and they can click a street to understand why it was scored that way. Please include the main flood indicators from the project, like street view features, elevation, slope, road type, and road width, plus scenario based risk views for rainfall levels like 30, 50, and 100 mm per hour. Make it feel like a clear planning tool for LGUs and DRRM teams, with simple explanations and a warning that the results are only model estimates and not for emergency use. If you need to, look up current docs online for Flutter, Maptiler, or any data handling details.
