Gutter and downspout size for Byrnes Mill rain
What overwhelms a gutter is a burst, not a season. In Byrnes Mill the five-minute rain expected about once in ten years falls at 7.57 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 950 square feet of roof and one 3-by-4-inch downspout about 1,900, by the rule in the Copper Development Association’s design handbook.
