We have a non-residential new construction campus project where the local authority has recommended 1028 spaces (no minimum or maximum). There are 425 new surface and garage spaces being constructed on-site. Staff and visitors for this campus campus will also be able to use 1500 garage and 238 surface spaces off-site.

A couple of questions:
The off-site parking is existing and we have not included it within our LEED boundary. Do we need to include these off-site spaces in our parking total?
If off-site spaces must be counted, but the garage/lot will be shared with other users, can we include only a portion of the off-site spaces in our total?
