A channel habitat ramp is an entrenched box-channel modification which allows wildlife access to and exit from the box channel condition. This modification is further described in Appendix I: Design Guidelines, Chapter 5 and requires hydraulic testing and coordination with an engineer before implementation.
Since box channel segments of the river are characterized by long stretches of tall perpendicular concrete wall, this can often either exclude or trap wildlife attempting to reach the water. The benefit of the ramp is that it can allow access and support plant communities such as the coast live oak woodland, chaparral, and the southern coast live oak riparian forest.
