Gutter and downspout size for West Whittier-Los Nietos rain
Gutters are sized for the worst few minutes of a storm, not for the year. In West Whittier-Los Nietos the five-minute rain expected about once in ten years falls at 3.25 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 2,220 square feet of roof and one 3-by-4-inch downspout about 4,430, by the rule in the Copper Development Association’s design handbook.

Half the homes in West Whittier-Los Nietos were built by 1954, 90% before 1980 (ACS 2020–2024). At that age a gutter has seen decades of leaves and storms, and the fascia it hangs from has too. On a house built before 1978, replacing more than 20 square feet of painted fascia or trim falls under the EPA’s lead-safe rule, so ask whether the crew is certified.
