Environmental Services is nearing completion of construction activities on a project to restore habitat along Johnson Creek near SE 73rd and Luther Road. The 76-inch diameter Lents Interceptor Sewer crosses Johnson Creek at the project site. Significant storm events in 2016 eroded the creek bed and banks and exposed a portion of the sewer pipe. This increased the possibility of pipe damage and blocked fish passage. A break in the pipe could release a significant amount of sewage and threaten public health and wildlife, including sensitive, threatened and endangered species. Repairing the storm damage and ensuring that the pipe is re-buried will protect public health and the environment by reducing the possibility of sewage releases to Johnson Creek.
Residents in the area may remember that this location was the site of a previous restoration project that restored habitat and buried the exposed sewer pipe. In summer and fall 2014, Environmental Services did extensive restoration work in the area. This project buried the sewer pipe crossing in Johnson Creek to stabilize it, established a new stable stream crossing, and moved the creek and its floodplain away from adjacent private property. Unfortunately, a major storm even in 2016 overwhelmed these repairs and exposed the pipe again. The new project has been designed to withstand larger storm events.
For more information about the 2014 Luther Road Restoration Project, please visit the previous project website.
All work in Johnson Creek has been completed. The work is now focused on restoring the upland areas of the site, as well as building new trails and restoring the viewpoint. It is anticipated that crews will complete construction activities in mid-November of 2019. Planting and other restoration work will continue through 2020.
