Site operations include stripping, extraction, processing, and recycling of concrete and asphalt reclamation. Materials suitable for reclamation will also be blended onsite with excavated aggregates. The applicant has previously received a CUP for this location. Portable Concrete Plant Portable concrete plants are used to produce materials for road construction, such as concrete pavement and bridge structures. The proposed plant will be located on site near the aggregate being sourced. The applicant has requested the concrete plant be portable and approved for the entirety of the site in order to keep the plant near the aggregate being sourced. Staff is recommending that the portable concrete plant maintain all setbacks outline for this site.
