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.

For their capstone projects, students in Civic and Environmental Engineering created designs, alternatives, scheduling, and costs to update a community center. Their work focused on several aspects of the building:  the parking lot, the building's entryway, layout and partition of the mainfloor, and connectivity of upstairs meeting room to entryway. This project is part of IISC's partnership with Pathfinders RC&D. 

For their final capstone project, students in Civil and Environmental Engineering designed a site plan for a subdivision on a currently vacant property in West Burlington. The plans maximize the number of single-family homes that can be developed and includes a pocket park and trail.

For their capstone project, Civil and Environmental Engineering students provided analysis, recommendations, designs, and costs to address flooding in West Burlington's Luers Park. 

Roughly 80% of West Burlington's stormwater drains into Luer’s Park, which in turn flows into Izaak Walton Lake to the north. The lake is experiencing severe erosion and sedimentation build-up. Its current outflow structure is unable to discharge an adequate volume of water. 

For their capstone project, students in Civil and Environmental Engineering designed a 10-foot wide trail that includes pedestrian cross improvements at several intersections. The trail will improve pedestrian safety and mobility for people traveling to and from essential shopping areas, schools, a medical center, senior housing, and recreation spaces. 

As part of their Senior Design Capstone course, Civil & Environmental Engineering students created site plans and designs for a small sustainability-focused "EcoVillage" in the unincorporated community of Scotch Grove, located in Jones County. 

Students in a Senior Capstone course in Civil and Environmental Engineering provided evaluation and design for a regional trail and trailhead connecting Scotch Grove with surrounding points of interest, such as Camp Courageous, Picture Rock Park, and the Cities of Anamosa and Monticello. 

As part of their Senior Capstone in Civil and Environmental Engineering, a team of students worked with Mahaska County Conservation staff on a project to enhance the county's water trails system, focusing on improvements to increase accessibility, use, and safety. 

As part of their Senior Design Capstone course, students in Civil and Environmental Engineering collaborated with Mahaska County Conservation to conduct a site assessment and design improvements for the White Oaks Nature Conservation Area. 

As part of their Senior Design Capstone Course, a team of students in Civil and Environmental Engineering designed a Public Works Facility for Bondurant's new Civic Campus. They devised three alternatives and created final designs with the client's input.

For their capstone project in Civil and Environmental Engineering, a team of students devised a way to connect two sections of the popular Chichaqua Valley Trail, and developed engineering designs and cost estimates to help the City of Bondurant implement the project.  

For their capstone project in Civil and Environmental Engineering, students researched best practices for cool and green roofs and applied their findings to the city-owned Five Flags Civic Center. 

Defined as a built environment that experiences higher temperatures than suburban or rural areas, all communities have areas that possess higher heat ratios due to more pavement, fewer trees, and other elements. These are often in downtown. Two increasingly popular methods for addressing urban heat islands are cool and green roofs.
