Hell Creek Stream Rehabilitation

Construction Project Insight

 Brittni Stephen-Yates & Nick Satko with CH2M


In the summer of 2015, the City of Omaha started the construction of a stream rehabilitation project for 3,300 feet of Hell Creek. The project includes removal of the trapezoidal concrete channel liner and replacement of four residential bridge culverts. The existing concrete liner was installed in the mid-1960s and was failing in several locations. Repairs were necessary to maintain the integrity of the channel and culverts, as well as to support public safety and provide flood management support. The project utilized bio-engineering techniques to rehabilitate the channel into a stable, more natural aquatic feature that better supports the ecosystem. The stream channel was re-constructed with a more natural appearance; with native grasses on the banks and cascading rock structures in the channel that provide better aquatic habitat in the channel. The project will be completed in the fall of 2016.

This presentation focuses on the final project results of the Hell Creek Stream Rehabilitation Project as construction will be near completion. Project benefits will be explained and lessons learned will be identified. Types of lessons learned that will be presented include construction methods of cross vane grade control structures and other technical elements, channel repairs made during construction to partially complete work after significant flooding events, bypass pumping challenges, public perception of the design, and paper versus real life design challenges.

Brittni Stephens-Yates is a Project Engineer with CH2M in the Omaha, Nebraska office. Brittni has worked on a wide variety of water/wastewater conveyance systems, treatment facilities, financial planning and water resources projects throughout the Midwest. She is currently working on hydraulic modeling and compliance requirements for the CSO Program and has been involved in the construction management of the Hell Creek Stream Rehabilitation Project, which she will be presenting on today. She holds a BS and MS in Environmental Engineering and a degree in Spanish from South Dakota State University. She is active in Engineers Without Borders with a project in Colombia (which she will be presenting on in March). Her other personal interests of hers include gardening and enjoying time with her husband and two daughters.

Nick Sutko is a Water Resource Engineer and Project Manager for CH2M.  He is a registered Professional Engineer in Nebraska and Kansas with more than 10 years of experience in planning, design and construction of wastewater, stormwater, green infrastructure, and conveyance systems.  Nick has been involved in a number of water resources engineering projects and communities dealing with CSO programs.  He has experience with hydraulic and hydrologic modeling, water quality modeling, stream restoration, and stormwater planning, and management.  Mr. Sutko has a Bachelor’s Degree in civil engineering and received a Master’s Degree in Environmental Engineering with a Minor in Water Resources Planning and Management from the University of Nebraska-Lincoln.
