I think everyone has a different idea of what a good family neighborhood is. If I were to compare it to the Chicago suburbs, I'd say there are no neighborhoods around here geared towards families. The inner Driftwood Estates is pretty nice though. Yards are decent size, there are sidewalks, and the county is adding a 10 acre park with playground, walking trail, bathrooms, etc.
I don't know how serious the drainage issue is. I've been here for a year and we've had a few good rains with no sign of flooding. Actually our ponds could really use some water. I think the main issue is that there is only one way in and one way out. If the state can get Sandestin to open up the other road to us, I think we'd hear less about the drainage issues. It could get pretty ugly if we all needed to evacuate quickly, or if the road was blocked for a period of time. But I doubt it would take long before someone drove their hummer through the Sandestin fence/wall, so I'm not too concerned.
I know it would never happen, but ...
They should stop the development of The Trails at Driftwood Estates (117 acres) and develop a forest preserve like you find in the Chicago suburbs. Lots of trees and a little something for us too. Hiking/biking trails, ponds for fishing, picnic areas, and some open green areas for playing, running, flying kites or whatever. It's just a dream though. They don't do that here. Our 9 red wolf/coyotes, 2 bobcats, great horned owls, box turtles, racoons, deer, squirrels, birds, etc. will have to move out.
