I have had the discussion in the office of what is a lifestyle center and in the world of real estate, we apparently like to run away from that word as much as possible. I can tell you that most of the centers in that list, including the St. Johns Town Center, are referred to simply as outdoor malls. Some centers like Avenue Viera (Atlanta developer that has that thing replicated like 10 times in the Atlanta metro) pretty much fit the bill (glorified power center with mall-like stores amidst some big box retailers).
We are listing two large centers in two different states that would fall in the lifestyle center umbrella as defined in this article, but we are actually calling them both power centers for short. These are centers that are attracting interest from the big guys only (because they are so large), and our partner in the listing is in Miami (a guy we partner with for everything). Apparently, as I'm still learning, "Lifestyle Centers" have not done nearly as well as they were predicted to, and so they have a huge stigma attached to them. One of our centers even has sales per SF of close to $500. Nope, not a lifestyle center...still a multi-phased power center with perhaps a lifestyle component.
There is a center (Summit) in Birmingham with just under a million SF of gross leasable area, and it is anchored among other things by a Saks Fifth Avenue, but we call it a power center (glorified as it may be).
Mary Brickell Village, City Place, Mizner Park, Old Hyde Park Village,and Winter Park Village are definitely not lifestyle centers, but rather a form of urban format shopping/infill. While not to the same level, saying Old Hyde Park Village is a lifestyle center would be akin to calling Highland Park Village in Dallas a lifestyle center (and that is in the same playing field as Bal Harbour Shops, and old). Atlantic Station in Atlanta is not a lifestyle center, either, but rather a redeveloped mixed-use brownfield. Outdoor does not necessarily mean lifestyle center.
In that list, true lifestyle centers include Waterford Lakes, Viera, and perhaps Market Street at Heath Brook and Destin Commons. There may be a few others, but once you start straying from having any big box and including traditional department stores and really upscale stores/purely mall stores and in a mall layout that happens to be outdoors, it's really just an outdoor mall.
I guess in short, a lifestyle center as thought of within the real estate industry is a power center in more attractive packaging, and a power center is an in-line/strip center with big box retailers. The more attractive packaging can be nicer facades, slightly more walkable environment, fountains, and of course a slew of smaller mall-stores. Viera and Waterford Lakes are the perfect examples here. They are also not over 600,000 SF large. Once you get to a certain point of massiveness, you are either a multi-phased power center or you are a mall.
SJTC attracts something like 10 million visitors a year, with like 30-35% coming from a distance of greater than 100 miles away. It has a power center component, but it's "lifestyle component" is anchored by a traditional mall department store that is still in its mall format. The layout is no different from a mall, but happens to have parking and sidewalks and landscaping in the middle. There will most likely be another department store and a few other upscale stores that either go in malls or on Fifth Avenue type streets joining this center. SJTC is owned by SPG, another indicator that it is most likely a mall taking advantage of good FL weather, a super-regional mall at that. I guess looking at the map in the picture provided, if you were to take away the newest section (green), maybe you could call this a power center with a lifestyle component, but that newest section turned this place into a mall and when more stuff gets built, it will even further resemble a mall.
Sorry to clarify here, but this is exactly my line of business for the time being at least.
