Our community-led ballot initiative revises “Chapter X – Park Development Limitation” in Lake Oswego’s City Charter, Chapter 1.

Chapter X was added to the City’s Charter in 1978 by a community ballot initiative to “preserve Springbrook Park as a natural area.” The community voted 3-1 in favor of this charter amendment to preserve Springbrook Park. The City’s Charter is its constitution. A Charter Amendment codifies the rules the City must abide by to the community it represents.
