*gulp* Ok, Ahhhemmm, well alrighty then. Am I allowed to even wishfully think that figure is in Bz$? Not that it would make a difference, so I'll just assume it's USD.
I'd conjecture that you'd find the communities and government on AC or even the mainland interests in the Caye hardpressed to come up with that kind of money. Particularly so when there is a critical need for projects more important to the peoples' immediate day to day lives. Projects such as an adequate, continuously clean water supply, adequate sewage systems, proper roads, funding of schools, and basic social services. Not to mention good basic fire and police services. After that or in conjunction with that, as you prefer, I suppose you can begin on the environmental laundry list. Projects such as restoration of critical mangrove habitat where illegal or improper land use was allowed and has left the island naked to the ravages of storms and erosion. Yet despite all I've mentioned the island has seen large donations of cash, better directed at such causes, donated and willingly accepted for items such as, oh, say 30' tall LED clocktowers situated in the middle of a crowded intersection.
The Caye is a unique community, and I will be very up front about the fact that I'm a newbie owner and learning how it works. But, perhaps like yourself, I'm interested in participating for the betterment of the island. So I ask questions like yourself and I learn things everyday that simply amaze me as far as how things are done. Many people here on the Board, and it is a diverse community in its own right, have repeatedly seen the kinds of questions you're asking. Dont take terse responses personally (I'm sure youre not, but just in case...) they're are simply giving you their best abreviated answers.
Headstrong individuals (particularly of the non-citizen kind) and their ideas seem to be categorically dismissed if their opinions or ideas differ, or don't coincide, with the current agenda or opinions of the incumbent leadership. We have a local mayoral election comming up and there may very well be a change for the better in that regard. I hope so, but its an uphill battle for the progressive independent candidate.
Other people have learned to work the ropes and are effective but they often have been here for years, are major players, well funded (or may purport themselves as such) and know how to work the politcal and administrative machine. Unfortunately not all of those folks are of pure mind and intent. While working the machine the populace at large has found that many such operators run the machine for a more self serving than altruistic purpose.
The other aspect of the kind of project you're proponing is mainteneance and upkeep. This touches on that topic to which Bywarren was alluding; equipment/programs of this type require a significant ongoing ops budget. Based on past record such political and fiscal committment has often been wanting on even simple projects like mooring or navigational bouys upkeep. (As to your question about why it takes so long to get things done or commit, the simple but true answer is, it's Belize)
Again, I think its a fantastic idea but given the fiscal (and physical) realities of the Caye, about which I am constantly reminded whenever I talk about improvements with friends and neighbors, headstrong efforts might be better placed elsewhere when it comes to improving emrgency services. As a suggestion work with the local fire department to enhance personnel training, keep existing equipment in good repair and most particularly, coming up with a cost effective way to provide additional water to fire fighting apparatus for the fires to which thay they can respond. The recent story about the total loss of the single moms house house becasue the responding unit ran out of water is a heartbreaker. Perhaps you saw it too. A water tender to provide backup might be better suited to the local FD's needs.
But even then such work, ideas, suggestions and plans needs to be done with respect, flexibility, and a sensitivity to toes, allegiances and alliances. At any rate, I thought I'd offer some broader comments on the realities as they have been presented to me in the past. Just sayin'.
