The visual impact of the Cerise Gravel Pit was evaluated as part of Resolution 2011-44. This
analysis was based on a mining and reclamation plan that involved a very large overburden pile,
and a large scale disturbance. Since these two major elements of the operation have changed, a
new visual analysis has been conducted. The new analysis uses the same viewpoints, and
baseline data, as the first analysis. Google Earth aerial data was used, along with inclusion of
some trees to partially simulate the effect of vegetation on the views.
Elevation differences between Wooden Deer Subdivision and the site means it is impossible to
completely obscure the operations. Therefore, the operator has designed the mine plan to
minimize disturbance as the operation goes on, and to leave the irrigated field portions of the
property in place as long as possible. The buffering and screening plan in this application works
with the reduced disturbance to mitigate the visual impacts of the Cerise Gravel Pit.
Additionally, the new mining plan eliminates the visual impact of concrete and asphalt plants.
On the following pages are screenshots from the visual models, both the original resolution, and
ones from the amendment application. Each screenshot represents the view from a height of 5'8"
off the ground from a particular view point. The Vantage Points map from the original resolution
is also attached to this section for reference.
