In 2012, the City conducted the Millers Creek Sediment Study in response to flooding on Geddes Road associated with sedimentation of Millers Creek in the City-owned Ruthven Nature Area. Millers Creek is a tributary of the Huron River located in northeast Ann Arbor. Millers Creek drains portions of property owned by the University of Michigan (31%) and property under the jurisdiction of the City of Ann Arbor (56%) and Ann Arbor Township (13%). The purpose of the study was to identify potential management recommendations for addressing the sedimentation occurring in Millers Creek at Ruthven Nature Area and associated flooding on Geddes Road. Recommendations from the study included sediment maintenance activities, sediment removal activities and sediment load reduction activities. This study included public engagement, with three public meetings for the neighbors.

Nearly 30% of the land in the Millers Creek watershed draining to the Huron River and its tributaries is impervious. As a result, stormwater frequently enters the river too quickly, causing erosion and sedimentation during certain rain events. The study identified a section of Millers Creek on City-owned property with the highest rate of sediment loss (identified in the study as Reach D). These rain events also carry pollutants from the impervious areas to the creek, lowering water quality. The proposed improvements will impr...
