Workshops & Demonstrations - Washtenaw County: Nichols Arboretum Site
Site Preparation

Several days prior to the demonstration project installation, the old concrete was removed, banks were graded to a stable slope, and rock rip-rap was installed at the toe of the bank. This was completed using equipment and crews from the City of Ann Arbor and Washtenaw County Road Commission.
