The Mill Creek Trail was completed by Origin Design in two phases. Phase I, a part of the Walkways for Life project, included replacement of Bellevue downtown sidewalks to make them ADA accessible and the creation of an approximately 1 mile loop trail in and around Felderman Park and along Mill Creek.
Phase II of the project, a pedestrian and bicycle trail, includes approximately 1400' of new concrete trail and a new bridge crossing Mill Creek between the City of Bellevue and Bellevue State Park.
The project included the replacement of five blocks of sidewalk along the business strip on Highway 52 and the connections via three side streets. Prior to the improvements, most business doorways had one to four steps to access the building and these were steps instead of curb ramps at the corners.
The selected design included modification of the curb and gutter to allow one level sidewalk where it is possible, and a two level sidewalk separated by railings at locations where the elevation differences were too great in accordance with the Americans with Disabilities Act (ADA).
The trail crossed a waterway which periodically floods. To accommodate the flooding, a low water crossing was designed which handles the flow in low flow conditions and will overflow across the trail during the flood events. Civil 3D was used to efficiently analyze multiple trail routes and grade alternatives to determine the best route for the project. The project also included routes from US 52 to Felderman Park and from HWY 62 to Felderman Park along the City street system.
The trail design met ADA requirements. Funding for the trail was provided through Vision Iowa, GREAT Places and local funding. Permit submittals to the Iowa DNR and USACE were also required.
