Creek Stabilization Project for Tributary to Dead Man’s Run in Taylor Park

Project Client: City of Lincoln
Project Location: Lincoln, Nebraska
Project Categories: Streams

The tributary in Taylor Park is a stream reach in a fully urbanized area of Lincoln that has been impacted by increased flows caused by urbanization, channel straightening and misdirected maintenance. The neighborhood park is heavily utilized by an active neighborhood association and surrounding neighborhood.

In order to provide a clear picture of the existing conditions of the stream segment, the project team performed a comprehensive, detailed survey including longitudinal profile descriptions, channel banks and cross-sections, thalweg determinations, hydraulic and hydrologic baselines, appropriate topography, inlet/outlet elevations, trees, utilities, hydraulic structures, etc. This provided data for the essential surface generation. A lowest opening survey was conducted and a fluvial geomorphologic assessment was performed of the existing stream conditions. The stream cross sectional data was essential for developing hydrologic and hydraulic modeling necessary for COE-regulatory review, Lancaster County floodplain development review, etc.

For the project, the prevalence of public use was considered in the design. The project team conducted two public meetings that invited comments from the active neighborhood association. The public meetings included illustrative drawings, 3D representations of project features and an in-depth discussion of the design approach. The public also had an opportunity to discuss the project components with individual members of the design team.

A series of “step-pools” or water quality cells are designed throughout the stream reach. These features will function as storage areas and primary sediment settling basins during high flow events and vegetated aquatic habitat features of the park during normal conditions.
