From the Washtenaw County website linked above:

The City of Ann Arbor petitioned the Washtenaw County Water Resources Commissioner (WCWRC) to undertake a project to design and construct stormwater management control measures for the Churchill Park Pond adjacent to the Churchill Downs Subdivision. The Malletts Creek Drainage District is an established Chapter 20 County Drain and falls under the jurisdiction of the WCWRC.

“Nearly 36% of the land in the Malletts Creek creekshed that drains to the Huron River and its tributaries is impervious, and as a result, stormwater frequently enters the river too quickly, causing localized and regional flooding during certain rain events. These rain events also carry pollutants from impervious areas to the creek, lowering water quality. The proposed improvements to the stormwater system will reduce the amount of stormwater entering the City’s stormwater piping network and reduce contaminant loading to the downstream creeks and the Huron River. The City is subject to a Total Maximum Daily Load (TMDL) restriction by the State of Michigan for biota (total suspended solids), E. coli and phosphorus. The proposed improvements will improve water quality and reduce localized flooding in the project areas.” (Excerpt from the City’s Resolution )
