It looks like you are referring to an out-of-date site plan for the residential, here is what is being built:

BTW, there are no existing streets on the master site. The industrial ring road around the site was removed on the southern side...not that it contributed to any sort of street grid. All the streets on the site are new and start to create a grid and to connect to one where it existed outside of the site. The parking where Kroger will go breaking up part of the new grid as shown on your referenced site plan. The residential buildings front the street where the new grid comes through and starts to create the "urban" conversation of buildings across the vehicular streets and pedestrian "streets". I think the parking ratio is something like 1.25 cars/unit, which would be less than 1 per bedroom. That is fairly dense.
