Rollings Game Production Area

Through the RFP process, CDI was chosen to help the South Dakota Game Fish & Parks (GF&P) transform this abandoned gravel mine into a state game production area and fishing park. Our responsibilities included performing a topographic survey of existing conditions which also included a bathymetric survey of existing pond depths. Existing conditions were then used to calculate needed pond excavations to create deep water habitat for game fish. In addition, the ponds were connected to provide one contiguous water surface thus requiring two pedestrian bridges for the walking trail around the pond. GF&P was interested in selling the gravel spoils on the commercial market but the quality of the excavated material was too sandy. CDI developed several alternatives including up to four pedestrian bridges and doubling the pond surface area; however, due to budget constraints, the final alternative was limited to two pedestrian bridges without doubling the pond surface area. CDI was instrumental in providing several pre-fabricated bridge options which included weathering steel, aluminum, and timber.  Two 8’ x 30’ timber bridges with a mild archway were chosen for aesthetic and cost reasons. CDI performed all calculations and design for the abutments which were founded on four steel piles each. The site also features two concrete parking areas which are compliant with ADA standards as are the walking trails and bridges. Also, the entrance road was improved and a new gravel boat launch was installed which featured a plastic geo-web. Two 40’ floating fishing piers were installed in the spring of 2012. 

Construction began in the late spring of 2011 and was completed late that summer. CDI also provided construction observation and inspection. Material testing was performed under contract by American Engineering & Testing. CDI provided all final design drawings and specifications, performed all construction administration and inspection, and construction staking.

This project was recognized in 2011 as an Outstanding Civil Engineering Achievement by the SD Eastern Branch of ASCE.
