In 1990 it became evident that unsupervised growth of urban areas can pose a threat to the environment and ultimately the quality of life in Washington. For example, if new apartments are built on certain farmlands and natural resource lands without considering how it will impact the environment and the economic development in the long term.
The adoption of the Growth Management Act regulated and enforced control over the urban growth and in a result helped to preserve the vital areas of the state. In particular, local governments received significant decision making capacity regarding implementation of the comprehensive plans and the urban development regulations.
