Before you rely on what you find
Treat these maps as a starting point. Parcel outlines are tax-map drawings and can be off from the true line; the recorded deed and a licensed survey are what count. To check flood zones, soils or wetlands for a spot you found, open it on the Platbookmapper Land Map, which pulls FEMA, USDA and U.S. Fish & Wildlife layers.
