Morning, I’m starting with calculations in SS credit 6.1 and 6.2 and I have a question: We are implementing rainwater recapture on our project for irrigation and toilet flushes. Our roof area is 10,000sq ft. The total site area is 80,000 sq ft. Is the calculation based on the proportion of square footage? Thanks...
