OUR PROJECT EXPERIENCE

Dubuque Mitigation Monitoring

A number of enhanced security measures were put into place after 9/11 which had an extensive impact to the functionality of the existing passenger terminal facility at the Dubuque Regional Airport outside Dubuque, Iowa. To document and analyze the functional constraints and deficiencies within the existing terminal, the Airport completed a Terminal Area Study (TAS) in 2005 which concluded the existing passenger terminal footprint was not designed to accommodate the demand taking place at the Airport. Therefore, the TAS recommended the Airport begin the process of developing a new passenger terminal facility to accommodate current and future passenger levels.

The recommendations in the TAS culminated in the development and design of a new terminal building and apron, parallel taxiway, parking lots, utility improvements, and a new airport entrance road. As a result of the proposed improvements, approximately 1,600 linear feet of an unnamed tributary to Lytle Creek was impacted. The original engineering design called for the enclosure of the tributary; however, coordination with the US Army Corps of Engineers resulted in the need to relocate the waterway rather than enclose. Prairie Engineers staff provided environmental surveys, agency coordination, permitting support, and design assistance regarding the relocation of the unnamed tributary and two separate crossings of Lytle Creek.

The relocated channel was designed to incorporate natural channel design with shallow meanders and riffle-pool structures. The riffles were constructed using the Newbury Weir method in order to create natural function while providing streambed stabilization. Additionally, longitudinal stone toe protection was applied to the outside bends to prevent channel migration. Construction observation and post-construction monitoring services were also provided. Prairie Engineers staff provided services on this project with another consultant and also through Prairie Engineers.
