The intent of the GB greenbelt zone district is to:

A.    Ensure that certain areas of Tumwater that are characterized by environmental sensitivity and value be preserved, for the most part, in their original undisturbed state.

B.    Provide and protect open space and other natural, physical assets of the community to improve the aesthetic and functional features of the community.

C.    Protect areas of environmental sensitivity and provide habitat for wildlife.

D.    Preserve significant natural areas for passive recreational use.

E.    Provide open space areas throughout the city and urban growth area to enhance the aesthetic quality of the community.

F.    Ensure the care and stewardship of open spaces in the city and urban growth area for future generations to enjoy.

G.    Provide for viable agricultural uses in the near term while realizing that, over time, these types of uses will be phased out of the greenbelt zone district.

(Ord. O95-035, Added, 12/19/1995)

18.30.020 Appropriate areas.

Areas appropriate for the greenbelt zone district are characterized by undeveloped public or private land that is permanently protected from development (except for trails and other passive recreational uses). These areas may include but are not limited to wetlands; wetland buffers; creek, stream or river corridors; open water bodies; forested areas; and ravines, bluffs or other geologically hazardous areas. The city recognizes the value of agricultural uses, but over time, it is expected that these uses will be phased out of areas under the greenbelt zone district. When a greenbelt is established to protect a wetland, the greenbelt zone district shown on the map(s) shall follow the actual delineated wetland edge.
