The Advisory Committee on Landslides provides advice and recommendations to the Secretary of the Interior through the Interagency Coordinating Committee on Landslide Hazard (ICCLH) on the implementation of the National Landslide Preparedness Act. The Advisory Committee’s membership and procedures are compliant with the Federal Advisory Committee Act (FACA).
