Not sure what to tell you bout that. I came across a site in google images that showed a legend for each phase of the site plan but it was not a clear image- hard to read.
You can contact Kyle at kyle@southbeachbelize.com. He should be able to clear up any questions or concerns you may have regarding the development. I have just been trying to get as much info as I can from here- Canada.
Sorry I couldn't be of more help.
