The soil in some areas of Arizona has “clay-like” tendencies, sometimes referred to as “expansive soil.” Other areas are subject to fissures, subsidence and other soil conditions. For additional information on earth fissures, visit www.azwater.gov/dwr/Content/Hot_Topics/Earth_Fissures_in_Arizona/Earth_Fissures_in_Arizona.pdf. Properties built on such soils may experience significant movement causing a major problem. If it has been disclosed that the property is subject to any such soil conditions or if the buyer has any concerns about the soil condition or observes evidence of cracking, the buyer should secure an independent assessment of the property and its structural integrity by a licensed, bonded, and insured professional engineer. To investigate areas in Arizona where expansive soils exist, go to www.az.nrcs.usda.gov (search “shrink/swell”) or www.azgs.az.gov (“Geologic Hazards”). A list of state certified professional engineers and firms can be found at www.btr.state.az.us.
