Fissures are a real threat in Arizona
![]() |
My husband and I found our dream home! An ideal home - a perfect place to raise our children, safely. Imagine our shock when my husband came in one morning and told us we don’t have a back yard anymore! What once was a safe play area for our children, literally overnight, opened up into a canyon across our entire yard and into our neighbor’s. The government authorities called it a “fissure.” Apparently, this one had been filled with dirt years ago before the developer even built the home! It had been there all this time. And we didn’t even know it. If we had known better, we could have easily checked the property for underground fissures before we purchased. We needed an independent third party to come to our home and test to determine if the property had a fissure running through it filled in with dirt – hiding the fissure. Only to later reopen threatening our safety and home. |
