Grabbing a non-contiguous park

SSc5.2 Userguide: "In a campus setting with no local zoning requirements, pen space that is equal to the building footprint can be considered separate from the project site, as long as the open space is preserved for the life of the building." This clause suggests that something like what you suggest is sometimes workable. Step 1 would be to check for previous CIR rulings to support what you'd like to do. Step 2 would be to clearly define and submit your own CIR. For SSc5, my gut feeling is probably not, unless the owner has direct influence / control on developement (or non developement) on the park grounds and could insure non-developement on the park grounds for the life of the proposed building (65 years?). As for SSc6, since this kind of run-off would have to be allowed by the owner of the park and some sort of aggreement drawn up between park and building owner AND you somehow channel your site run-off ACROSS the road for infiltration on park grounds, then it would probably fly. The implications of executing such a plan probably won't.
