The real challenge for the Los Angeles River is the ecological compromise for the existing riparian habitat. It’s a huge challenge to reproduce the historical elements with limited vegetation since normal terraces couldn’t occupy in LA river condition in the way of providing a flexible and temporary structure for flood control. In this case, the pilot project is proposing a series of modified grid ridge structures (geo-blocks) on the concrete riverbank to help restore the natural habitat of Los Angeles River. The goal of this pilot project is to experiment with an intermediate form between the concrete and soft bottom to achieve the ecological and aesthetic revitalization of the Los Angeles River.
