Strengths and Limitations
- Top 3 strengths
- Fills a data gap for a Delta-adjacent area other Bay tools skip
- Consistent methodology with the Bay-wide Flood Explorer
- Locally reviewed data
- Top 3 limitations
- Very narrow geography
- Same today's-shoreline limitation as the Bay-wide tool
- Lives on its own subdomain, so it's easy to miss from the Bay explorer's main page
