The Miami County Board of County Commission held a study session on July 30, 2025, focusing on traffic studies related to a proposed quarry expansion. The meeting began with discussions on the anticipated traffic impacts from the quarry, specifically the expected 107 vehicle trips per day generated by quarry operations, which includes both incoming and outgoing traffic.

Commissioners reviewed current traffic counts on nearby roads, noting that Hospital Drive sees approximately 1,880 vehicles daily, while Hedge Lane north of the quarry site has about 1,470 vehicles per day. The discussion highlighted the importance of understanding existing traffic patterns to assess the need for infrastructure improvements, such as left turn lanes, particularly for vehicles turning into the quarry.

The board also addressed the permitting process for the quarry, emphasizing that the conditional use permit (CUP) from the county is a prerequisite for further state and federal approvals. The quarry's compliance with air quality regulations and other environmental standards was confirmed, but the commissioners noted that the quarry cannot operate without both county and state approvals.

Concerns were raised regarding the potential tracking of debris onto public roads from quarry trucks. In response, the board discussed conditions that would require the applicant to pave the quarry entrance and implement measures to minimize debris, such as regular road sweeping and the use of tracking pads.

Overall, the meeting underscored the need for thorough traffic studies and regulatory compliance as the county navigates the complexities of quarry operations and their impact on local infrastructure. The board plans to continue monitoring the situation and will require further assessments as the project progresses.
