Weather and gutters in Black Diamond
NOAA Atlas 14 does not cover Washington and Oregon, so there is no current federal estimate of the short downpour for Black Diamond; NOAA plans published Atlas 15 estimates for the lower 48 states no earlier than September 2027. Here gutters are sized from the roof and the local building department’s design rate.
The houses in Black Diamond
Half the homes in Black Diamond were built by 1997, 24% before 1980 (ACS 2020–2024). In a neighborhood that young, many houses still have the gutters the builder put up, and the usual call is a cleaning, a leak or guards rather than a full replacement.
87% of households own their home, and 91% of homes are detached houses, 2% townhouses. Where an HOA governs the exterior, its rules on gutter color and style apply before any order is placed.
