Parking is impervious and therefore not counted. • What about green roofs? Will a green roof count towards perviousness requirement? Answer: As for Green roofs, every applicant that comes in is strongly encouraged to do green roofs. Green roofs are not considered to be pervious because they are limited in how much water they can absorb. DPS would determine if credit can be given for green roofs. • When staff talks about the plan impacting carbon emissions, will it be impacted up or down? Answer: Currently, staff does not know if emissions will go up or down because the modeling for it has not be done yet.
