The airspace design process is extremely complex. See for example this FAA document, Order 7400.2M.
To what FAA office or personnel should one direct an inquiry about the reasons behind the design of the airspace around one particular airport?
I'm specifically seeking information about why the airspace was designed that way, not about how it is being handled now in actual practice by ARTCC etc.
These two airspaces are rather unusual and it's unlikely that a satisfactory answer will be obtained just by perusing the FAA documents giving general guidance on how to design airspace to handle existing/ proposed instrument procedures, etc.
However any kind of actual "paper trail" relating to the design of the airspace at these two particular airports could possibly be helpful, if it were not too "dense" to interpret -- how might that be obtained?
But I'd prefer to speak to an actual person, if he/she had some relevant insight on the design process for the airspace at either of these airports.
Although guidance concerning my specific case is most welcome, also I'm seeking an answer crafted in such a way as to be helpful to anyone seeking to answer a similar question for any airport in any region of the nation-- how to go about locating an appropriate person or FAA office to direct such a query toward?
