I have to agree that you can not create a downtown from scratch by having one story buildings. You need to have tall buildings to even attempt to do that, and even then I'm not sure it would work.
Let's face it though. Jacksonville isn't going to become the type of urban community we would like to have until much tighter land-use regulations are put in place. Right now we are doing are best to become the Houston of Northeast Florida: nothing but endless sprawl, poorly constructed suburban growth, and poor traffic.
Why can't we get some developers with the forsight to build some really tall buildings in the city's core? The only city in the state that seems to be building a skyline is Miami. The rest of the state seems content with the kind of cheap suburban growth that will be very difficult to continue this century with rising fuel costs and poor traffic. Downtown Jacksonville is such a beautiful area and has so much potential, that it makes me sick seeing it go to waste. How many municipalities have the kind of picturesque setting we have, with 5 bridges spanning the river downtown? Not that many, I can assure you.
The city should be providing tax incentives for those who restore old and delapidated buildings as well as provide huge tax incentives for those who are willing to build some more skyscrapers downtown. Of course, that will never happen, not with the incompetence of John Peyton and the often uninterested attitude of the city's citizens.
