Jefferson County Park consists of 254 acres that includes seven miles of hiking and biking trails winding through timber, prairie, wetlands, prairie savannas, and ponds. It is located  just south of the City of Fairfield and is the most-visited of all parks and properties stewarded by Jefferson County Conservation. With an aim to increase park usage and improve facilities, a group of five Civil & Environmental Engineering capstone students were asked to design cabins and a large multi-use structure. This project is part of IISC's partnership with Pathfinders RC&D. 

The team designed several components for the complex project, which they broke into phases according to the order in which they should be built. In the first phase, they designed Park Road, an eastern parking lot, and a nature playscape. The second phase included two year-round cabins, each of which contains two bedrooms, one bathroom, and a living space. It also included an access road to the structures. The final and third phase focused on the multi-purpose lodge that includes a 300-person event rental space, a nature center with an educational classroom, ADA-compliant bathrooms, and accompanying parking.

Throughout the project, the team planned for site grading and drainage. They provided drawings, pricing breakdowns, construction phasing and schedules, and design alternatives.
