By the age of its homes it sits among the newest by median year built of the 938 places in California on this site (half built by 1986).

When to clean gutters in Oak Park
The first fall frost comes around December 15 in a typical year here, and the last spring frost around January 24 (median dates, NOAA normals). A fall cleaning set for the weeks after that frost, when the branches over the house are bare, gets the year’s leaves in one trip; a spring visit follows once the pollen and catkins have come down.
When to clean gutters explains how the trees over a roof change the schedule.
Gutter and downspout size for Oak Park rain
Gutters are sized for the worst few minutes of a storm, not for the year. In Oak Park 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. Try your own roof in the gutter and downspout calculator, which starts from this figure.
