The Local Actions Non-Dam Alternative (LAND)

While reducing flood damage in the Chehalis Basin is urgent, it also requires serious thought and consideration to conserve the Basin’s rich ecosystem.

The Local Actions Non-Dam (LAND) Alternative is an effort to develop and evaluate a comprehensive, Basin-wide flood damage reduction approach that includes alternatives to the flood retention dam proposed by the Flood Control Zone District—taking into account long-term flood damage reduction, impacts on local wildlife, impacts on residents and businesses, and cost.

The LAND team leading the effort is now engaging with the area’s city and county planners, residents, the local business community, technical experts from state agencies, local and tribal governments, and others.
