When to clean gutters in Aliso Viejo

Gutter and downspout size for Aliso Viejo rain
What overwhelms a gutter is a burst, not a season. In Aliso Viejo the five-minute rain expected about once in ten years falls at 3.89 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 1,850 square feet of roof and one 3-by-4-inch downspout about 3,700, 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.
Aliso Viejo is dry by national standards, about 13 inches in a normal year, but much of the rain that does come can arrive in short, hard storms: the five-minute downpour expected once in ten years still runs at 3.89 inches an hour. Where gutters are used here, the job is moving that burst away from the foundation, and keeping a dry season’s dust and debris from blocking the first storm.
The houses in Aliso Viejo
Half the homes in Aliso Viejo were built by 1995, 5% before 1980 (ACS 2020–2024). In a neighborhood that age, many houses are on their second set of gutters or due for one, and the fascia board behind them is worth checking at the same visit.
57% of households own their home, and 36% of homes are detached houses, 25% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
