What is the floor of the Class E airspace over the town of Auburn?

In the context of airspace classification, Class E airspace typically starts at either 1,200 feet above ground level (AGL) or at a lower altitude when associated with airports that have instrument approach procedures. Specifically, in areas where there is no specific terminal airspace designated, Class E transitions to other airspaces at 1,200 feet AGL, unless otherwise specified by regulations.

The floor of Class E airspace can also be at 700 feet AGL in certain locations, especially in conjunction with the airspace needed for smaller airports or when it is necessary to provide controlled airspace for specific purposes. If a town, like Auburn, is situated in an area where the airspace begins at 700 feet AGL, this would be the correct designation for the floor of Class E airspace.

This indicates that for regions such as Auburn, the definition of Class E airspace parameters is pertinent to safe flight operations, aligning with federal aviation regulations. The designation at 700 feet AGL effectively allows for the safe accommodation of both general aviation and possible approaches, ensuring pilots are aware of the airspace structure they are flying within.
