A project I'm working on has a large undeveloped area that we'd like to include in the open space calculations and the design calls for adding the necessary features to promote physical interaction with the outdoor space. However, there is the potential for some of that area to be developed in the future (the owner does not currently have plans, but cannot say for sure if there will be development years down the road at this time). In LEED v2009 there was the specific requirement to preserve all open space that is counted toward this credit for the life of the building. It seems like this requirement has been removed for v4. Is that the case or am I missing something?
