Groundcheck

Floodplain and wetlands check

Check a property for mapped floodplain and wetlands

Flood hazard areas and mapped wetlands can affect where you build, what you investigate, and which agencies you contact. Groundcheck puts these screens beside the parcel and other site conditions.

Official public data sources. Clear risk levels. Practical next questions.

Generate a Groundcheck Report

Enter a property address to start your screening report.

Your first Groundcheck Report is free. Each additional report is $29.

What you get

See more than a yes or no result

Groundcheck explains which mapped features intersect the parcel, cites the public source, and places the finding alongside soils, slope, surface water, roads, and environmental context.

Check FEMA data

Screen the parcel against available FEMA National Flood Hazard Layer features.

Check mapped wetlands

Review National Wetlands Inventory features that intersect or sit near the property.

Keep the limits clear

See plain-language caveats and next questions instead of treating a map as a final field determination.

Property checks

What Groundcheck screens

  • FEMA flood zones and mapped hazard features
  • National Wetlands Inventory intersections
  • Mapped streams and surface-water features
  • Parcel boundary or address-point screening area
  • Soils, slope, and drainage context
  • Source links and recommended follow-up questions

Available parcel, state, and local data varies by location. Every report shows the sources used and any unavailable checks.

How it works

From an address to a clearer next step

  1. 1

    Enter the property's street address.

  2. 2

    Groundcheck compares the parcel with available floodplain, wetlands, and related data.

  3. 3

    Review the mapped findings and confirm important results with the proper agencies and professionals.

Common questions

Before you rely on a property screen

How do I check whether a property is in a flood zone?

FEMA's National Flood Hazard Layer is the main national screening source. Groundcheck checks available FEMA features for the property and includes the source and follow-up context in one report.

Does a wetlands map prove that wetlands are present or absent?

No. The National Wetlands Inventory is a screening dataset, not a regulatory or field delineation. Unmapped wetlands can exist, and mapped boundaries can differ from field conditions.

What should I do when Groundcheck finds a floodplain or wetland?

Review where the feature sits on the parcel, then contact the appropriate local, state, or federal agency and a qualified professional before relying on it for acquisition, design, or permitting.

Check floodplain and wetlands

Groundcheck is an early-stage screening tool. It does not provide a legal, engineering, surveying, environmental, planning, permitting, or buildability determination. Verify important findings with qualified professionals and the appropriate agencies.
