Sustainable Flood-Risk Reduction

摘要

Kevin Holden, a leading landscape architect with the U.S. Army Corps of Engineers, is working to make flood-risk-reduction projects more sustainable-for communities, for the environment, and for the Corps. Here are the two key principles:rnWide Flood-Protection Right-of-Way. When new levees and floodwalls are built, they should be moved farther back from the river. This creates a wider floodplain within which the river can spread out, and it also opens opportunities for natural restoration of the f loodplain. Set-back levees are also easier to maintain, because both sides are accessible.
