Know the flood
risk before
it costs you.

FEMA maps are often 15–20 years out of date. Tidemark Risk Firm delivers hyper-local flood risk reports that go further — combining geospatial analysis, impaired waterway data, upstream development, and historical flood events into one clear, actionable report.

// The problem with standard flood maps

FEMA maps tell you where the water was.

We tell you where it's going — and what's changed upstream since the last update.

📅
Maps Are Outdated
The average FEMA FIRM map is 15–20 years old. Upstream development, climate shifts, and aging infrastructure have fundamentally changed flood patterns in most markets.
🏗️
Upstream Development Changes Everything
Every new parking lot and subdivision upstream increases runoff velocity. A property rated Zone X in 2005 may carry significantly higher flood risk today.
🌊
Impaired Waterways Increase Risk
Streams listed on state 303(d) impairment lists face degraded flow capacity — but this data never appears on a standard FIRM map.
⚖️
Disclosure Liability Is Real
Flood disclosure litigation is rising. A Tidemark report provides documented due diligence that protects agents, attorneys, and buyers from post-sale disputes.
