Lol, I just visited friends last month who moved their 11 and 8 year old kids from Jax to Harlem because they felt Jax didn't offer their children enough culture. For the US, that's about as urban as it is going to get, compared to life in Jax. The 11-year-old kid already knows the subway lines better than his mom.
"Urbanity" in Jax is all relative because all of it's still pretty low density. However, there aren't many places in Jax where a certain amount of people can rent a space above 20,000-square-feet of retail/dining and a park, walk to work (assuming you work at Fidelity, BCBS, TU, Haskell, etc.), and be within a block of a full service grocery store, 50,000 additional square feet of retail/dining and the Northbank Riverwalk. As more growth happens, that little node of mixed use activity stand out more in a sprawling city like Jax. Having DT and Riverside/Avondale within short biking/driving distance and direct access to I-10/I-95 are additional positives.
Like the mom who beat her rioting kid in Baltimore, yeah Jax's little slice of urbanity isn't as good as most peer communities, but it's still our little developing node. Might as well enjoy it.
