A few weeks ago I got out and took some pictures and Sunnyside Hills was one of the neighborhoods. Sunnyside Hills boarders the main arterials 67th and Sunnyside Boulevard and is part of the greater Sunnyside Neighborhood according to the City of Marysville's Comprehensive Plan. It is one of Marysville's older neighborhoods which makes it a great place for new buyers and investment property owners.
The schools that serve Sunnyside Hills are Sunnyside Elementary, Marysville Middle School, Marysville Junior High and Marysville Pilchuck High School. I went to all three of the schools while I live two blocks North of Sunnyside Hills. It was also one my favorite spots to go trick-or-treating and to play around.
