We have a resort site located overseas that is about 2980 acres. 30% (84 acres) is a previously undeveloped greenfield jungle area. The rest is land that has been cleared and graded for development previously (about 5 years ago). There were buildings and infrastructure that occupied about 20% of the developed area (196 acres) until a year ago. We are treating this site as a hybrid site using Case 1 for the jungle area and using Case 2 for the balance of the site.
Since we are not in the US, what will we need in terms of documentation to prove that the 196 acres was developed? Pictures or local government documents possibly? Credit SS 5.1 is not in the LEED 2009 for New Construction ACP Guidelines. Anything above and beyond what is listed on the Document Toolkit tab for this credit? Any guidance is appreciated.
