On this website our intent is to help educate you about Elevation Certificates as we provide in Phoenix Arizona. The information is beneficial to everyone involved in the process. There should be no surprises.
The Phoenix Arizona Land Surveyor provides the information, via the Elevation Certificate form, which provides the data which determines the flood risk for your home or business. The Land Surveyor cannot guarantee the Flood Elevation Certificate will result in low insurance rates, they only provide the required data. FEMA, in conjunction with the local government in charge of flood control, determines flood zones.
There are 4 primary Flood Zones found in Phoenix, Arizona. They are Zone A, Zone AO, Zone AH and Zone AE.
Zone A - Phoenix - Flood Zone A defines an area which has at least a 1 percent annual chance of flooding but no detailed anylisis has been done to determine the actual Base Flood Elevation or depth
<Zone AO - Phoenix - Flood Zone AO defines an area which has at least a 1 percent annual chance of shallow flooding of 3 feet or less in a large area with flowing water. There will be a Flood Depth given, most often being 1 foot, which has been calulated by a detailed analysis of the area
