Agreed. It will likely take Ashford over a decade to complete this massive project, and work likely won't even begin until Downing Street has been converted into a mixed use boulevard, and the new cross street behind Assumption has been created.
That infrastructure project alone may take a couple of years to complete. I would not be at all surprised if it isn't until 2025 before we start seeing shovels in the ground for any actual building construction, and, as you say, probably the first one to be built will be the relocated Farmers Market, and maybe a new downtown library building.
Instead of letting this land lay fallow for five years or so, Ashford has decided to pave it over for temporary parking and make some money off it. This is just a business decision. In the universal scheme of things, this doesn't mean a thing.
