Salt Creek Main Stem Improvement near Old Cheney
Grade stabilization and bank repair adjacent to Old Cheney. Being done in coordination with County, Parks and NRD
This project is located in the South Salt Creek watershed (SSC-4) and is along Salt Creek Main Stem just north of Old Cheney. The City of Lincoln is coordinating with the County, Parks & Recreation, and the NRD to construct a grade control and stilling basin just north of the bridge to protect the bridge piers and channel, and to prevent erosion from continuing upstream.
Salt Creek Main Stem Improvement near Pioneers
Grade stabilization and bank repair adjacent to Pioneers. Being done in coordination with County, Parks and NRD
The Lower Platte South Natural Resources District, the City of Lincoln Watershed Management and Lancaster County worked together on the design and construction of the Salt Creek Channel Stabilization Project located at 200 Pioneers Blvd. The project is the South Salt Creek Watershed Master Plan’s Project #3 and is listed as a high priority.
Map of Project (373 K)
The final design to stabilize the channel and protect the bridge included the following:
- Geomorphic Stream Assessment was performed to assess the pre‐project conditions of Salt Creek and determine the dominant process driving erosion and instability. The dominant channel process in the project area is widening characterized by large failure scarps in the channel banks. In addition, a two foot tall knickpoint in the channel immediately downstream of the Pioneers Blvd Bridge indicates past incision. An eight foot deep scour hole had also formed downstream of the bridge.
- Grade Control Structures were constructed to stop future incision. Two grade controls were constructed, the first structure is immediately downstream of the bridge at the knickpoint location and is constructed of 48” diameter boulders. This boulder structure protects the bridge abutments and is shaped to turn flow to the center of the channel and into the eight foot deep scour hole. The second grade control structure is located at the downstream end of the scour hole to protect the project from future downstream incision and to keep the flow exiting the scour hole and project reach in the center of the channel.
- Bio‐Engineering Bank Stabilization was used to stabilize eroding banks. The banks were regraded to a flatter, stable slope and vegetated rock toes constructed to protect the lower slope against high flow energy. The middle and upper slopes were protected with biodegradable fabric and waddles and vegetated with native riparian corridor vegetation to provide a robust riparian corridor and abundant natural habitat throughout the project reach. The restoration planting palette included Buttonbush, Roughleaf Dogwood, Redosier Dogwood, Peachleaf Willow, Elderberry, Shrub Indigo, Eastern Cottonwood, Black Oak, Snowberry, Bald Cypress and a restoration seed mix containing 17 native forbs and 5 native grasses.
- Rock Armor was used on both banks under the bridge to cover the exposed bridge piers and protect the bridge from future erosion.
- Environmental Permitting for the project included wetland delineation and 404 permitting.
