Since the LEED Online form doesn't have an Option 4 choice, you'll need to indicate with the checkbox under "Additional Details" that you're using an alternative compliance path. For more information, see LEEDuser's analysis of the ITE study.
Question
If a non-residential project wants to use Option 4, which references the ITE Parking Generation Study, where does one upload and submit required documentation? There is no Option 4 choice in the credit form.
