One of the final ideas is to share Miramar with the military. Other cities have a shared military civilian airfield.

Airport noise does reduce property values, but I don’t know how much.

This is the most current I could find on the subject:

County voters are slated to vote on a location for a new airport — or an expansion of Lindbergh — in November 2006.

The possible sites for a new airport include an Imperial Valley desert location, an all-but-abandoned Borrego Springs site and a site in Campo. Five military sites also under consideration are March Air Reserve Base in Riverside County, two sites at Miramar Marine Corps Air Station in San Diego, Camp Pendleton, and North Island Naval Air Station in Coronado.
