Thirty years ago, urban streams were perceived as little more than flood control devices designed to hurry water through cities and neighborhoods with scant thought for aesthetics or ecological considerations. But stream restoration pioneers like hydrologist Ann Riley argued that by restoring ecological function, and with careful management, streams and rivers could be a net benefit to cities, instead of a net liability. Riley has since spearheaded numerous urban stream restoration projects and put to rest the long-held misconception that degraded urban streams are beyond help.What has been missing, however, is detailed guidance for restoration practitioners wanting to undertake similar urban stream restoration projects that worked with, rather than against, nature. This book presents the author thirty years of practical experience managing long-term stream and river restoration projects in heavily degraded urban environments. Although the case studies are local, the principles, methods, and tools are universal, and can be applied in almost any city in the world.
