I am working on a building on a hospital campus. The Site Boundary over which the charity building owner has a lease includes an area (about 1/5 of the total site area) that is to be landscaped by the hospital campus i.e. we will just leave this area empty at the end of construction and the hospital will complete landscaping at some stage. This means that we do not have any details on what the landscaping design will be (although the masterplan indicates that the site will be landscaped with local native plants). Can I exclude the section that will be landscaped by the campus but ultimately within the boundary of area we have a lease over? Or do I have to wait / push a 3rd party to provide suitable documentation showing he landscape design of this space. This obviously impacts the irrigation credit and the site selection credits.
