Strengths and Limitations
- Top 3 strengths
- Extremely easy for non-experts to use
- Covers the whole U.S. coastline, not just California
- Good first-pass screening for any one location
- Top 3 limitations
- Simplified “bathtub” style mapping, not a dynamic flood model
- Not built for detailed infrastructure or economic exposure analysis
- Less California-specific detail than the state-built tools
