Pennington County Jail expansion approved to double capacity with 600 new beds

In a pivotal meeting held on March 6, 2025, the Rapid City Planning Commission addressed significant developments impacting the community, including a major expansion of the Pennington County Jail and new conditional use permits for local businesses.

The most notable discussion centered around the proposed expansion of the Pennington County Jail, located at 307 Saint Joseph Street. This ambitious project aims to double the jail's capacity from 600 to 1,200 beds, necessitating a five-story addition. The expansion is designed to enhance public safety and accommodate the growing needs of the community. The new facility will include officer stations, cells, and recreational areas, with a focus on improving the transfer process for detainees through a newly proposed Sally Port. This enclosed area will facilitate safer transfers and alleviate traffic congestion on Saint Joseph Street, which has been a concern for local residents.

Commission members expressed support for the project, recognizing the importance of addressing public safety needs as the community continues to grow. The proposal also includes modifications to existing facilities, such as upgrades to medical services. Despite a decrease in parking spaces due to the expansion, a previous study confirmed that sufficient parking remains available, ensuring that the project will not lead to shortages.

In addition to the jail expansion, the commission reviewed two conditional use permits for local businesses. The first permit allows "Old School Sliders," a new restaurant at 2120 West Main Street, to serve beer alongside its menu. This establishment, already operational, will offer canned and draft beer, with plans to extend its hours in the future. The commission noted that the restaurant is well-buffered from residential areas, minimizing potential disturbances.

The second permit pertains to a new event space at the Clubhouse Hotel and Suites on Hope Court, which will serve alcohol exclusively during private events. This venue aims to enhance the local hospitality scene while ensuring that alcohol service is managed responsibly.

As the meeting concluded, the commission unanimously approved the jail expansion and both business permits, reflecting a commitment to balancing community growth with public safety and local economic development. The decisions made during this meeting are set to shape the future of Rapid City, addressing both immediate needs and long-term goals for the area.
