Probably not, but it's the closest thing to a Disney like recreation of the real thing that I've seen in this area.
I actually don't hate Rivertown, Julington Plantation, WGV, Bartram, Palencia or Nocatee, all of them appeal to a particular market segment that Jacksonville doesn't really offer anywhere else. The time is coming when we'll see a flurry of community incorporations and it's interesting to speculate on which will pull the trigger first and how much real estate it will involve.
As for the 'back door' to Rivertown, I was going over their plans and it appears they plan to do a Palencia/Tapestry type central business district between SR-13 and the Amenity Center.
Access to 210 would absolutely change the face of the community and those connecting roads are not far from reality.
I am rather fascinated by the extensive trail system and the USEABLE amount of natural area's that will be connected to the trail system. I live just up the road from Rivertown and the trails have already been put to good use, the little guy on the dock in that photo is my 'mini-me,' grandson, also named Robert.
