      4.   "Viewshed analysis" means describe, map, and provide photos of the predevelopment viewsheds from representative locations on the scenic route (at approximately four feet above existing grade) looking at and through the development site. From the same perspectives, illustrate the post-development viewsheds.

The two-hundred-foot area of applicability is measured as follows:
