Gutter and downspout size for Walnut rain
The short, hard downpour is what a gutter is sized for. In Walnut the five-minute rain expected about once in ten years falls at 7.96 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 900 square feet of roof and one 3-by-4-inch downspout about 1,810, by the rule in the Copper Development Association’s design handbook. Try your own roof in the gutter and downspout calculator, which starts from this figure.
The houses in Walnut
Half the homes in Walnut were built by 1938, 93% before 1980 (ACS 2020–2024). Houses that age have often had their gutters replaced once already; if not, the original runs and the boards behind them deserve a close look. 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.
72% of households own their home, and 86% of homes are detached houses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
