Staff recommends approval with conditions for Dixie Lee Quarry expansion; commission flagged buffers and road closure as separate county action

Staff recommended approval, with conditions, of Vulcan Materials’ request to expand the Dixie Lee Quarry north of the Watt Road interchange. Staff said the quarry’s primary access is from Everett Road, noted the site’s prior 2009 expansion and emphasized that any closure or reroute of Graybeal Road would be a county-commission action separate from the planning commission’s approval of the quarry expansion.

Planner (identified in the agenda as Mike Rans) described buffer and berm commitments the applicant is proposing and staff’s recommended conditions. He said the zoning ordinance requires a minimum 100-foot buffer where a quarry abuts residential zoning and that the applicant’s plan shows a larger berm in places; in one scenario staff showed a 360-foot distance from the closest property line to the pit. Rans said staff is recommending approval subject to eight conditions covering consistency with supplemental quarry regulations, construction of the berm, tree preservation and planting, performance standards for nuisance controls (noise, odor), lighting orientation and return of any reroute concept to the planning commission for review.

Rans also summarized operational time limits shown in the applicant’s plan of operations: construction of the berm is limited to 7 a.m. to 6 p.m.; blasting is listed in the plan of operations as restricted to daytime hours (the staff report provides a 9 a.m. to 4 p.m. window); and operations in portions of the site zoned agricultural are limited to 7 a.m. to 9 p.m., Monday through Saturday. He emphasized the applicant has provided setbacks and additional screening beyond the minimums in the zoning ordinance.

Commissioners asked for clarification about whether setbacks would remain if Graybeal Road were rerouted; staff said any reroute or road-closure decision is separate and would return as a concept plan if pursued. One commissioner asked whether the 100-foot setback would need to be extended if the road were moved; staff responded that some plan options show larger distances and the applicant is proposing additional buffering and berming beyond the ordinance minimums.

Why it matters: the expansion would extend quarry operations closer to existing residential areas and involves commitments on buffers, berms, hours and lighting. The proposal also raises jurisdictional questions because the potential closure or realignment of Graybeal Road falls to the county commission rather than the planning commission.
