5. Plantings shall not adversely affect adjacent protected water resources or existing native vegetation through shading or invasion by plant species.

6. Non-native invasive species are prohibited.

7. Planting or replanting within an identified view corridor shown on Figure 9.3155(3) shall not include any trees or large shrub species.
