The Project will remove approximately 6,300 cubic yards of soil which are suitable for disposal at a Class III landfill or for use in an industrial site. Trimming of native trees, and removal of some native and non-native trees, shrubs and vegetation will be required to prepare the project site for earth moving activities and installation of park components. New planting and landscaping will be included in the Project as well as new or modified gates and fencing.
