The City and GRWW’s proposed location of the AHS structure is approximately one mile upstream of the Sixth Street Dam and will be located just downstream of the train trestle bridge that crosses the Grand River south of Ann Street. This location is at the head of the historic, and regionally rare, limestone rapids and will provide enhanced access to approximately 88 acres of limestone bedrock habitat. 

This location also creates additional opportunities to reimagine our city parks and trail system as envisioned by the River For All community master plan. If the AHS was the selected alternative for the upper reach project and built at this site, and if the public safety hazards created by the existing dams are removed, there would be ample opportunities to think differently about flood protection and to provide improved access to the river in downstream city parks.
