Project summary

Edit project overview to modify the project summary.


This site is a 574 foot reach of ephemeral stream channel located behind Kauffman Park and the local Senior Citizens’ center. As with the other sites, erosion and public safety were the major issues here. Also of note, the contractor brought in a second crew to be able to meet the project construction deadline by being able to work on sites simultaneously. However, both crews were active on this site due to the number of structures required. Seven constructed rock/log riffles were incorporated throughout the design for energy dissipation. Four were located at the upstream end of the project at various points along the meander bend of the channel. Two cross-vane structures followed for grade control and to ensure that flow was directed toward the center of the channel. A third cross-vane was located at the downstream boundary of the project. Between the second and third cross-vanes, were 3 log drop structures and 3 additional rock/log riffles. Streambanks were regraded with gentler slopes and floodplain grading was performed beginning just downstream of the first cross-vane structure to the end of the project site.
