A landscape plan must be submitted for approval. The plan must factor in site-specific conditions, including topography, adjacent structures, and roadways, and, to the greatest extent practicable, shall minimize visual impacts by preserving natural vegetation, creating berms, and providing landscape screening to abutting properties, roads, public lands and properties, such as, but not limited to, parks and trails, and environmentally sensitive resources. A visual assessment of the effects of the project on visual character and scenic resources may be required.
