Amazon is offering $20 million to the Arlington County Affordable Housing Investment Fund in exchange for being allowed to build a bigger headquarters complex in the county than zoning allows. In exchange for the donation, Amazon hopes to increase the allowable size of its new ZGF Architects-designed HQ. Additionally, the company plans to create 25,000 new jobs and invest $2.5 billion in building its headquarters in the Pentagon City and Crystal City neighborhoods over the next decade.
