Our building will occupy a whole city block with no parking on that particular block. We are defining our LEED project as the building plus approximately 26% of a parking deck (and of the landscaped area around it), with the parking deck located in a block diagonally across from the building. The new parking deck will serve four buildings by the same owner, with zoning requiring 1,358 spaces total, and the deck providing 1,550 spaces. Zoning for our building requires 407 spaces. We are planning to allocate 407 parking spaces operationally (with parking passes for the building occupants and a set-aside for visitors within the 407 spaces) rather than with physical barriers in the parking deck. Please let us know whether this operational allocation is acceptable for obtaining SS Credit 4.4, or what else we need to do. We also want to use the 407 spaces as a basis for the total vehicle capacity for SS Credit 4.3, Alternative Fuel Refueling Stations. Is this acceptable for the base number in this question?
It is acceptable to allocate a portion of the parking deck to the LEED project. Allocate a proportional amount of the parking deck from the ground up, including both the covered and top deck spaces. You will need to provide convincing documentation that limits the number of parking spaces to the code minimum, and that the other spaces in the parking structure are not providing capacity beyond the LEED requirement. If the parking deck is included in one credit, it must be included in all other applicable credit calculations. The alternative-fuel refueling stations should be calculated from the allocated parking space total. Applicable Internationally.
