When to clean gutters in Irwindale

Gutter and downspout size for Irwindale rain
The short, hard downpour is what a gutter is sized for. In Irwindale the five-minute rain expected about once in ten years falls at 3.59 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 2,010 square feet of roof and one 3-by-4-inch downspout about 4,010, by the rule in the Copper Development Association’s design handbook.
