I have a large mixed use retail/office project that is interested in using the discounted parking rate option to comply with this credit but is finding logistical issues. The parking garage will be fully automated - push a button for ticket on your way in, pay via machine on your way out. Has anyone implemented the discounted rate approach in this type of situation? How did you do it? Incredibly high tech or costly computer programs are likely not an option for this tightly budgeted project.
