A. Removal of a dead, substantially diseased or damaged, or hazard tree is allowed upon submittal of written verification by a qualified arborist who states that removal of the tree is essential for the protection of life, limb, or property. Removal of significant trees as defined in GHMC 17.99.590 may require replacement per GHMC 17.99.240(E).

B. Plant Compatibility. All new plantings must be of a type which will thrive amid existing vegetation without killing or overtaking it. Incompatible plants which require different planting environments or microclimates shall not be mixed. Haphazard mixture of textures, colors and plant types should be avoided. Invasive, nuisance plants on the noxious weed list (state and Pierce County) are prohibited.

C. Irrigation. Planting areas with nursery stock or transplanted vegetation shall include an automatic mechanical irrigation system designed for full coverage of the planting area. Exceptions may be granted for native planting plans that provide temporary irrigation for at least three growing seasons.

D. Wall Coverage. Blank walls shall include a narrow planting area, where feasible, with shrubs or vines (espaliers) giving coverage to the wall.

E. Preservation of Significant Views. Views and vistas from public rights-of-way shall be considered when determining placement of vegetation. While it is not the intent to avoid all trees in the foreground of a view, consideration should be given to the expected height of tree and how they might be located to “frame” the view. (Ord. 1347 § 46, 2016; Ord. 1086 § 4, 2007).
