Dowe Flats Special Use Permit Amendment Application May 2, 2022 <br /> Allowing CEMEX, Inc. to continue to mine the mineral resources found on the site rather than <br /> abandon it, promotes and supports the use of a local product and available resources. <br /> 4. The use will not result in an over-intensive use of land or excessive depletion of natural <br /> resources. In evaluating the intensity of the use, the Board should consider the extent of <br /> the proposed development in relation to parcel size and the natural <br /> landscape/topography; the area of impermeable surface; the amount of blasting, grading, <br /> or other alternation of the natural topography; the elimination or disruption of <br /> agricultural lands; the effect on significant natural areas and environmental resources; <br /> the disturbance of plant and animal habitat, and wildlife migration corridors; the <br /> relationship of the proposed development to natural hazards; and available mitigation <br /> measures such as the preservation of open lands, the addition or restoration of natural <br /> features and screening, the reduction or rearrangement of structures and land <br /> disturbance, and the use of sustainable construction techniques, resource use, and <br /> transportation management. <br /> This SUP application is being made to allow CEMEX, Inc. to continue mining Dowe Flats for an <br /> additional 15 years. The original permit, approved in 1993, estimated that the resource at the <br /> quarry would be fully mined out by the end of 2021, but there is more resource than anticipated. <br /> If CEMEX, Inc. continues to mine the mineral resources that are all within the currently <br /> permitted disturbance boundary, no additional land will be disturbed. In addition, the mine <br /> would continue to operate in the way it has historically where the product is mined and <br /> processed on-site and then sent via covered conveyor to CEMEX, Inc.'s cement plant for use. <br /> There is no history of compatibility complaints associated with the Dowe Flats mine, confirming <br /> that it is a low-impact operation. There are also no natural hazards associated with continuing to <br /> mine the resource from this site. Once the remaining resource is removed in accordance with <br /> this permit amendment, CEMEX, Inc. will reclaim the land and then facilitate its transfer to <br /> Boulder County where it will be preserved as open space and integrated into the County's <br /> parks, open space, and trails network. Therefore, the request being made will not result in an <br /> over-intensive use of land or excessive depletion of a natural resource, and the intensity of the <br /> use is appropriate for this site. <br /> 5. The use will not have a material adverse effect on community capital improvement <br /> programs. <br /> Continuing to mine Dowe Flats will have no adverse effect on community capital improvement <br /> programs. Rather, continued mining of this site will more likely have a positive effect on <br /> community capital improvement programs because of the cost savings associated with having a <br /> nearby source of mineral resources for the CEMEX, Inc. cement plant. Having local resources <br /> available that are necessary to make the cement helps to keep the cost of cement down. <br /> CEMEX, Inc.'s cement plant likely provides the cement used to make concrete for projects <br /> constructed throughout Boulder County as the next closest cement plant is in Pueblo. <br /> 6. The use will not require a level of community facilities and services greater than that <br /> which is available. <br /> Continued mining operations at Dowe Flats through this SUP amendment will not increase the <br /> need for any community facilities or services beyond what is currently being provided. At this <br /> time, only emergency response services are provided to the site and Dowe Flats has not <br /> generated any significant demand on those services because the quarry has historically <br /> operated in a safe manner. <br /> Review Criteria Statement- Page 8 O TETRA TECH <br />
