I disagree with the statement "Tampa/St. Pete" being far....
DT Tampa to DTSP (23.8 miles -- 30 minutes)
Jacksonville to JAX Beach (18 miles -- 30 minutes)
I relocated back to Tampa after finishing undergrad at UNF in 2013. Prior to Buckhorn I wanted to flee Tampa. Since my return, I have noticed a renaissance emerging more infill, a greater sense of civic pride, weekly festivals, more local businesses/restaurants, greater focus on globalization and diversity (Copa Airlines, upcoming direct flight Frankfurt via Lufthansa).
Seminole Heights (Riverside esque) is beginning to see urban infill along Florida Ave. kind of like Edgewood Ave in Murray Hill. More coffee shops, and "Hipsters" moving in. Green ARTery going live in 2018 similar to Atlanta Beltline on a smaller scale.
Hyde Park great neighborhood for the young and old
Ybor City beginning to see another boom, and more tech companies....
Westshore gaining steam on infill and international presence for tourists and natives.
Downtown (Core): Gaining traction with all of the aforementioned, Selmon Greenway, more infill (2) approved 23+ story towers, a couple of mid-size projects, plus "Vinikville"
I'm finally seeing "hope" however, I still want MASS TRANSIT (commuter or light rail)! The city wants it however there's a political struggle since the county lacks the will and prefers "BRT." Mayor recently announced to fund streetcar and get the ball rolling for Vinik. Viking (Lightning owner) wants mixed-use, neighborhood, with transit. Vinik wants to break ground on his project this summer. Hopefully, will see modern conversion + line going to Seminole Heights by end of decade. Within 10 years I truly think Tampa/Tampa Bay will become more "urbanized."
Jacksonville IMO has the potential to be one of the greatest metro's in the SE. There has to be a political and social will to utilize assets, and bring in diversity. JAX should really push for a greater international presence. It's still "home" to me as I have family and close friends however I was ready to depart once I walked across the stage. It would be cool to see some 23-30+ story residential towers in Brooklyn/LaVilla, and of course the core.
