Existing Parking Lot

For a NC 2009 project we are building an addition to a building on an which will replace part of an existing campus parking lot. The campus provides parking in existing parking garages on the campus, and all the spaces had previously been used for hospital valet. Although this existing parking lot will be connected to an a roadway with our building entrance, the parking spaces do not support the new building connection. Do we need to count this existing parking lot in our LEED Boundary line if we are not taking account for the spaces and we are not ripping up and putting down a new parking lot in this area. We ask because it makes our LEED boundary a little funky to exclude this space but lose some credits by including the additional areas which are not a part of our scope.
