Why is the City prone to flooding?
Flooding along Issaquah Creek, Tibbetts Creek and other nearby streams is a natural phenomenon due to the fact that much of the City is located in a floodplain. Historically, areas within Issaquah that are located along streams and prone to flooding were developed as farmlands. As such, the farm properties were only minimally affected by high water. Early newspaper accounts generally wrote of flooded farmlands washed out roads, and an occasional flooded basement.
