kids creek restoration project
Restoring an urban gem
Kids Creek, a cherished stream on Traverse City’s west side, is on the State of Michigan’s Impaired Water’s List due to a poor macroinvertebrate (aquatic insect) community, mainly because of stormwater issues. Kids Creek drains almost 7 square miles and is a major tributary to the Boardman River, a State Designated Natural River. It experiences severe changes in flow due to stormwater inputs during rain and snowmelt events and exhibits extreme flashiness, often flooding portions of the urban area within Traverse City. This flashiness has led to scoured stream bottoms and increased sedimentation from eroding stream banks within the creek, causing a lack of habitat for aquatic insects. Additionally, contaminated runoff from road salt in winter may be negatively affecting aquatic insect populations in the creek. The Michigan Department of Natural Resources (MDNR) Fisheries Division considers Kids Creek an important and critical spawning stream, nursery stream, and coldwater contributor to Grand Traverse Bay in Lake Michigan.
In 2013, The Watershed Center worked with the Michigan Department of Environment, Great Lakes and Energy (EGLE), the U.S. Environmental Protection Agency (EPA), and many other partners to draft and begin implementation of an Action Plan for Kids Creek to address water quality issues and highlight priority tasks aimed at helping improve water quality. This began The Watershed Center’s large-scale Kids Creek Restoration Project with the goal of reducing the impact of stormwater and sedimentation on Kids Creek and its tributaries so it can be removed from the Impaired Waters List.
More than $9 million in grant funds have been acquired to implement key portions of the project, including funding from EGLE, EPA-Great Lakes Restoration Initiative, National Oceanic and Atmospheric Administration, Great Lakes Fishery Trust, and private foundations. Project work has focused on reducing stormwater inputs to Kids Creek from urban areas using green infrastructure and low impact development techniques. In conjunction with these projects, the next components of the Kids Creek Restoration Project focus on replacing undersized road crossings, increasing infiltration through the restoration of riparian corridors, providing stream bank stability, increasing floodplain storage during periods of high flow within and alongside the channel, and restoring in-stream habitat and natural stream function.
Completed work includes installation of bioretention/rain gardens, underground infiltration trenches, downspout planter boxes, pervious pavement, green roofs, storm tree boxes, road crossing replacements, and stormwater wetlands. These practices have increased stormwater storage volume in the watershed by more than 100,000 cubic feet and reduced hundreds of millions of gallons of stormwater runoff to the creek. Additionally, stream restoration and floodplain reconnection activities have been completed along 2,475 feet of Kids Creek tributaries. All installed practices combined account for annual pollutant reductions of 274 tons of sediment, 383 pounds of phosphorous, and 1,359 pounds of nitrogen.
