Iowa’s River Restoration Toolbox
Iowa’s River Restoration Toolbox is a series of best management practices developed to assist designers in stream stabilization and restoration projects in Iowa with proven techniques with emphasis on incorporating natural materials, such as logs, stone, and live plantings. Among the dozens of techniques described in the Toolbox are longitudinal peaked stone toe protection, j-hook vanes, rock arch rapids, oxbows, riparian corridor restorations, and tree/shrub plantings. It delivers a consistent, relevant assessment method and reviewable design checklists to aid decision making among multidisciplinary teams (i.e. – restoration practitioner, engineer, project manager, funder, biologist, etc.). The toolbox also provides detailed drawings and specification requirements to make natural stabilization projects more biddable.
