CM.Goal S: Provide for timely reclamation and reuse of mining sites in accordance
with the Comprehensive Plan, Subdivision and Zaning Ordinances.
This site will be reclaimed into unlined groundwater-fed ponds, lined water storage
reservoirs, as well as silt basin wetland and upland areas, uses which are consistent with
the County Regulations.
CM.Goal 6: The extraction of mineral resources should conserve the land and
minimize the impact on surrounding land.
Lafarge is working with the U.S. Army Corps of Engineers, the U.S. Fish and Wildlife
Service, the U.S. Environmental Protection Agency and the Colorado Division of
Wildlife to preserve or minimize impacts to sensitive habitat on the site as well as
adjacent properties. Portions of the Riverbend site are located with the Fort Lupton
Urban Growth Planning Area. Lafarge has worked with the City of Fort Lupton to
develop a reclamation plan that is consistent with the City of Fort Lupton Land Use
Plan, which they are curretttly in the process of updating. This update will include an
expansion of the Fort Lupton Urban Growth Planning Area, which will include the
majority of the Riverbend site.
Consistency with Weld County Code (addresses USR Questionnaire, Item #3)
This applicant will conduct operations in a manner which is consistent with the design
standards and operations standards as set forth in Chapter 23, Division 4 Sections 23-2-240 and
23-2-250, respectively, of the Weld County Code.
Compatibility with Surrounding Land Uses (addresses USR Questionnaire, Item #6)
The proposed operation is compatible with the surrounding land uses. Several existing mining
operations are located immediately to the south, north and east of this site. Agricultural and
low density residential land uses lie to the west of the project. The South Platte River is
located to the south and east of the proposed facility. The processing area will be located on
the southeastern portion of the property and surrounded by material stockpiles to mitigate
noise. Lafarge will also construct berms along the eastern mine boundary near the entrance to
the site to help reduce noise impacts and the visual impact of the proposed operation.
Consistent with the Weld County Code, mining will not occur nearer than 10 feet of an
adjacent property line or within 125 feet of any existing residence (refer to the Mining Plan
Map for specific locations of the mining boundaries and the homes). The site will be reclaimed
as unlined groundwater-fed ponds, lined water storage reservoirs and silt basin wetland and
upland areas. This use is permitted as a special use in the existing zone and is compatible with
agricultural uses.
Method of Mining Operation (addresses USR Questionnaire, Items #1, #8h)
The typical mining procedure for all phases will be as follows. Any areas slated for
protection will be identified in the field to assure that mining operations will be set back as
appropriate. Initially, the topsoil and overburden will be stripped with scrapers and
stockpiled in the designated stockpile areas identified in Exhibit C. Overburden will also
be used to construct berms and as fill in the 3:1 reclamation slopes. Following stripping of
the overburden, the deposit will be dry mined through the use of dewatering trenches and
pumps. Overburden and topsoil stockpiles will be drilled and seeded as appropriate to
