Gutter and downspout size for American Canyon rain
The short, hard downpour is what a gutter is sized for. In American Canyon the five-minute rain expected about once in ten years falls at 2.64 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 2,730 square feet of roof and one 3-by-4-inch downspout about 5,450, by the rule in the Copper Development Association’s design handbook.
