The RFP specifies that Amazon is looking at 500,000 square feet of office space or 100 acres of greenfields for phase 1. Ultimately, the site will need to accommodate 8 million square feet of office space.
Baltimore has an advantage that it already has a site and project ready-to-go that meet those requirements. Port Covington a 235 acre redevelopment project already approved with a $500 million tax incentive has already been given to build the infrastructure for Under Armour's new global headquarters.
I'm on a Facebook Group with other local publishers around the country and its amazing to see people from Northern Virginia, Boston, and Austin act like something like this would be a hassle that would bring too many people and drive up real estate prices further. Similarly, I have seen reactions from people in Seattle who are thankful that Amazon may turn its attention elsewhere for a little while and give them a respite from the housing market pressures. Though, I wouldn't be especially confident that there would be much respite.
What a different perspective there is somewhere like Baltimore where unemployment and underemployment is still a huge problem.
