The Willamette Water Supply System (WWSS), a transformative infrastructure project designed to provide reliable, high-quality drinking water to 350,000 residents in Washington County, is in the final stages of construction before delivering water for Tualatin Valley Water District (TVWD) customers, including those in the Cedar Mill, Cedar Hills, and Bethany areas in 2026.

As a child in South Korea, Jisook Kim discovered her lifelong passion for calligraphy, a handwriting style that expresses art through characters and symbols. She continued to pursue this passion in college, where she majored in graphic design and took classes on fonts in handwriting. However, this passion slowly faded away as she took in more responsibilities as a mother and a wife—until the pandemic. When the world was put on lockdown, she used her free time to take online calligraphy classes.

This summer marked a heartfelt milestone in Cedar Mill history: the 75th anniversary of a cherished family home that has stood as a hearth of warmth, tradition, and togetherness since 1950.

Nestled across the street from Cedar Mill Elementary School, the house was built by Ralph Leppert and his then 17-year-old son, Arnie Leppert. Hammer in hand, young Arnie helped raise the walls that would hold generations of laughter and love. Now, in a beautiful twist of time, Arnie celebrates his 90th birthday this year—an occasion that adds even more meaning to the home’s anniversary.
