The current system of sediment management in Southern California is economically and environmentally unsustainable

It will:• cost $3-5 billion in the next 20 years• aggravate human health risks (heavy equipment emissions, noise,

traffic, dust, precludes natural flushing events)• rob downstream landscapes and ecosystems of their essential

building blocks (fine sediments, sands, gravel, nutrients, etc.)

And it won’t solve the problem �
