Walton county has a total full-time population of around 50,000 today, with about four thousand families with kids spread out across the entire county. What you describe doesn't fit with the demographics of the area, nor does the initial and ongoing cost fit with the median income levels we have here. How much would something like this cost to maintain? Debt does not magically disappear, it must be paid off. Pretty much the only way to pay for this ‘Kampus’ is through taxes, both property and sales. Those methods spread the cost across the entire county. I don't think folks in Defuniak, Piney Grove, Freeport, or for that matter, Miramar Beach, are going to be happy about funding a sports complex for a small privileged group, especially when you consider the income disparities between the northern and southern regions.
I'm sorry but I would not support something like this if it came to a vote. This smacks of an idea hatched by the "30-A crowd" which would clearly under serve a majority of Walton County residents. Case and point, quoting your proposal: “The growth of the eastern area of South Walton, as evidenced by the continued development of Point Washington, Seagrove, Grayton, Eastern Lake, WaterColor, WaterSound Beach, WaterSound, Seaside, Rosemary Beach and Sea Crest, shows the need for an additional sports recreation facility in this part of the county.” Of all the demographic areas in Walton County, I can assure you, the 30-A corridor is last on the list in need of frivolous, taxpayer funded facilities.
Also, isn't most of this already available either publically or privately? I think most of these resources are, just not in one grand 200 acre shining complex. (Conveniently located just north of 30-A.)
Now I wouldn't have any issues with parents asking for a couple soccer fields at the local high school or a new park or small ampatheater, but what S.P.E.A.K. is describing here seems more suited to a large metropolitan area or a very rich, niche enclave, like, oh I don't know, maybe Aspen Colorado?
My suggestion for the folks interested in this would be to get your expectations more in line with the fiscal and demographic realities of area you live in. (Also, if Seaside’s Neighborhood School is in need of a new lacrosse field, might I suggest the folks who send their kids there band together, buy the land, and build one.)
You should start by knocking on Joe's front door, they have a habit of investing in these types of things and a vested interest in seeing the area grow.
