I have a project on an island in South Korea. Two previously separated islands by shallow sea have been joined together 20 years ago by an area of reclaimed land built for the construction of an International Airport. This area is part of a Free Economic Zone designated by the Korean Government in 2003 which is already under development, all infrastructure is already existing.
The project owner has bought a small portion of the land now, however there has never been any hardscape built on it.

After having read a thread in SSc1 and the Supplemental Guide I am worried if my project can pursue LEED certification, as acc. to MPR Supplemental Guide: Page 18: “Previously developed support structures and artificial land mass: ‘Buildings located on previously constructed ….. and infill, and other manufactured structures in or above water are permissible, provided that artificial land is previously developed (i.e., the land once supported another building or hardscape constructed for a purpose other than the development of the LEED project).”

I am wondering if this also applies for my site as
1. The reclamation was made 20 years ago for the purpose of economic & infrastructure development by the Government
2. The reclamation was not specifically undertaken for our project
3. The project owner has not reclaimed the land, the land was bought several years after the reclamation was done

Has anyone any experience with similar cases?
Any advice/comments?
