Churchill Downs Park Stormwater Basin
Churchill Downs Project
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)
January 7, 2022 - Project Update (email)
- EGLE (formerly the DEQ) has received everything they need to issue a permit. It is still in draft form but I expect to have the final version in hand promptly.
- We are pulling together the final design elements and coordinating with the reconstruction of Scio Church Road (City of Ann Arbor). We’re at, let’s say, 90%.
- We’ll have a information session on Zoom on Jan 25 at 6:30PM. Find additional information and a link to the meeting in the Calendar Event.
- We’ll send out postcard invites to the neighborhood, post on NextDoor and send individual letters to adjacent property owners. If you know of someone who live adjacent to the construction please pass word of the meeting along to them.
September 17, 2021 - Project Update (email)
- Permit draft received – Working with EGLE (MI Environment, Great Lakes, and Energy) for issuance
- Design can now be finalized, incorporating changes/requirements identified in the permit
- Project costs increased due to permit requirements/changes – reviewing the potential to utilize American Rescue Plan funding to finance this project rather than paying for it directly from the stormwater utility
- Project out for bid by end of 2021 (estimated)
- Spring 2022 construction possible, pending receipt of reasonable bids. More information on the schedule will be provided when available.
- Scio Church road project is similarly delayed until next spring – may overlap with this project
NEXT: Public Meeting to be scheduled (end of 2021) to go over the design, impacts on park use during construction and post-construction. An e-mail notice will be sent with details of the meeting. Please contact Harry Sheehan, Chief Deputy Water Resources Commissioner Email Harry Sheehan or call 734-222-6851 with any questions or to be added to the email list for this project.
March 4, 2021 - Project Update Virtual Meetings - 12 pm & 7 pm
Virtual update meetings on this project will be held on March 4th at 12 noon and 7 pm. Please join us at either time. Both meetings will provide the same information: Background, Current design, Plans for the playground and other park amenities, Timelines, and Challenges ahead to bring this project to fruition. Please contact Harry Sheehan, Chief Deputy Water Resources Commissioner Email Harry Sheehan or call 734-222-6851 with any questions. Additional information is available on the City of Ann Arbor website: www.a2gov.org/lanschurch
This study outlines this project as part of the recommended solutions to reduce the severity and probability of future surface flooding in the Upper Malletts Creek watershed.
September 24, 2020 - Walkthrough
A walkthrough of the 2021 construction project (with physical distancing) was held on Thursday, Sept 24th at 5:30 pm.
August 12, 2020 - Public Meeting
The Churchill Downs stormwater basin meeting was an online meeting. Together with the project engineer, the background, conceptual design, schedule, and construction activity were reviewed along with a question & answer session.
"To improve drainage and reduce flooding, the construction of a stormwater detention pond has been proposed on the Eisenhower Park property, located in the southeast quadrant of the Scio Church Rd / I-94 overpass in Ann Arbor, MI. To accommodate this construction, a large portion of the wooded area in the park will need to cleared and the area will need to be regraded. The goal of this study is twofold. (i) To evaluate several pond configurations to determine how the proposed changes will affect acoustic environment. (ii) To explore the potential for future noise abatement. This report summarizes the data that has been collected and the preliminary analysis that has been completed in the course of the study."
