Yes, you may use the city\'s standard college parking ratio to set the parking capacity limit for LEED comparison. For carpool space calculations, it is acceptable to use 145 for the number of students and staff, based on your explanation for an adjusted building population count. LEED will require 4 carpool spaces for your project (using the formula in the Reference Guide). The project must designate the appropriate number of carpool spaces as near as possible to the facility. These do not have to be newly built spaces, just newly designated. Although as a campus you have some flexibility in locating the spaces, you will need to demonstrate that the spaces are close enough to primarily serve this building, and thereby meet the intent of this credit. In your case, the proposed lot (150 feet away) will suffice.
