According to a site map that the county plans to submit to Amazon, officials have cobbled together multiple parcels for its bid that flank Talen stadium, home to Major League Soccer's Philadelphia Union. The parcels — many of which are parking lots or industrial land — are owned by multiple entities, both public and private, public records indicate, though a spokeswoman for Delaware County said the owners have indicated they are willing to sell. The sites potentially offer local tax incentives, such as the Keystone Opportunity Zone, to encourage redevelopment, officials said.
