Project Overview: The 580-acre property was the site of an operating refinery from 1911 to 1981. As part of site redevelopment, Trihydro completed the stormwater management and floodplain mitigation plan for the site. Trihydro performed flood-stage water profile simulations for the numerous creeks and channels, which cross the property and feed into the Illinois and Michigan (I&M) Canal, and the Chicago Sanitary and Ship Canal on the west boundary of the site. The Des Plaines River is also in close proximity to the site. Trihydro performed runoff and flood routing simulations of the 10-, 25-, 50-, and 100-year design rainfall events. Based on these simulations, Trihydro completed preliminary designs for the stormwater collection, detention, and discharge infrastructure.

To further facilitate site redevelopment, Trihydro has completed, or is in the process of completing, designs and construction supervision for several infrastructure projects, including:

• Water and sewer mains
• A wastewater lift station and force mains
• Stormwater collection, detention, discharge systems
• A bike path and bridges along the historic I & M Canal
• Road construction and bridge refurbishment

Client: University of Wyoming
Location: Laramie, Wyoming
Project Overview: Trihydro was contracted to conduct stormwater and utility planning for the University of Wyoming for a Conference, Convention, and Commercial Development. A primary objective of this engineering study will be to evaluate alternatives for relocating and reducing the size of a detention pond to facilitate development of the Plaza. The study will address both the feasibility and cost of a number of alternatives, including eliminating the need for large-scale stormwater detention at the site.

Design of the utility infrastructure is also an important consideration in developing an understanding of the cost and range of feasible alternatives for development of the Plaza at the site. Principle issues include the existing capacity of sanitary sewer mains serving this area of the Campus, and construction of a service connection to Laramie 's municipal water system.

Thus, a second objective of the study will be to identify the least cost alternative for construction of the utilities infrastructure needed to support development of the Plaza. The study will include an evaluation of the existing sewer system and strategies to develop sanitary service to the Plaza. Likewise, needed infrastructure development for establishing water service to the Plaza will be identified.
