Riparian Landside Right-of-Way

Riparian habitat can be created on the landside of the right-of-way through grading and landform activities. This can be done without affecting the flood capacity of the channel because it does not require levee or channel wall modifications for implementation. Interventions should not negatively impact the structural integrity of the levee, and planting near levees should follow the most recent USACE guidelines. An example of this kind of habitat is the Dominguez Gap Wetlands in Long Beach. This cross section can greatly improve water quality if storm drains are daylighted and filtered through the wetland before reaching the river.

With regular access to water, this cross section supports riparian plant communities such as perennial freshwater wetlands and southern sycamore riparian woodlands. The ability to support trees as well as shrubs allows for wildlife habitat for species such as black terns and yellow warblers.

* The wildlife species listed in these examples are potential key indicator species and are not meant to be a comprehensive list, since wildlife is found in a variety of contexts given specific site conditions. * These profiles are not a substitute for good ecological design led by ecologists, landscape architects, and engineers. The use of biodiversity profiles while further engaging qualified ecologists and scientists in projects can help to add additional ecological data on a project-by-project basis.
