IIW worked with the City of DeWitt to convert an existing dirt trail to an ADA compliant paved trail.
The 10’ wide trail has a total length of 1.3 miles in a loop network, connecting the public sidewalk to the on-site bridges and the main trail in Westbrook park. In addition to its scenic, wooded pathway, aesthetic features include trail signage and bump-outs with benches for users to sit and enjoy the scenery. Modifications were made to existing bridges at the site to improve abutments, including repair and prevention of erosion.
The trail required an Iowa DNR floodplain construction permit, associated wetlands delineation, and archaeological investigation. In order to obtain the permit, a HEC-RAS analysis was performed to verify that the construction proposed within the floodplain did not increase backwater elevations on adjacent properties.
The design also involved public involvement to discuss how best to minimize the removal of trees, and consider trail alignment options to provide access to the playground, ball fields, and Frisbee disc course already sited at the park.
The trail was well received by the public, as demonstrated by many letters to the editor of the local newspaper.
IIW provided trail design, regulatory compliance and permitting activities, generating plans for a local bid letting, survey, and construction services, including on-site quality control observation, staking, and management.
