It looks like alot, but I personally think it’s rather conservative seeing as much of it is the airport itself or employment areas, and seeing how large greenfield areas are elsewhere.
That’s not entirely a bad thing, but it is an ongoing conflict point with developers, and I am not entirely sold on the city’s premises. Essentially all residential growth will be in Elfrida and along White Church, both relatively distant from either the city or airport.
Almost all of this land has an active application of some sort, so there is indeed a thirst for more residential land. But I digress. Given the densities needed to meet growth targets, it will not be very “sprawl”-like anyway.
