Designing a trail with several amenities to serve the community.
The City of Dubuque Leisure Services Department partnered with Origin Design to develop the City-owned area around an existing pond in the Dubuque Industrial Center West. The project was completed in two phases.
During Phase I several amenities were added to the facility, including an ADA compliant trail, bump-outs for benches, a restroom facility, PCC trail, fishing pier, grading for the addition of playground equipment, parking lot lighting, lighted flagpoles and electrical service to an existing gazebo.
Plans specified a segmental block retaining wall, but trail excavation exposed a natural shale wall so the design was modified. A 10’ wide pedestrian bridge was added to the project to span a drainage way since the existing rock did not allow excavation to place a culvert. The restroom facility featured limestone facing, a veranda and cedar soffit to compliment the natural environment and better match the existing gazebo building. The trail tied together existing elements at the facility including a shelter, fishing pier and playground site.
The project schedule enabled design and construction to be accomplished in the same year.
During Phase II of the project and as a part of the Dubuque Industrial Center West development, an ADA accessible grass trail was designed following the sanitary sewer alignment. As the City’s budget allowed, the 1.88 mile trail was fine graded and paved as a 10’ wide HMA trail with 2’ wide shoulders on each side.
Design services included design survey, alternative analysis, preliminary and final trail design, regulatory compliance, restroom design, including water and sanitary services, preparation of plans for a local letting and field services.
A parking lot, with lighting, was designed to serve as a trailhead, where the trail ends at Pennsylvania Avenue. The parking lot driveway was located to allow safe access onto Pennsylvania Avenue considering intersection visibility.
Services provided during construction included staking, change orders, pay requests, shop drawing review and final project certification.
