As of 2007, the City of Chicago and the Army Corps of Engineers were considering a $2.65 million feasibility study to look at restoration options, which would have implications for the remainder of the Chicago River system due to the unusual challenges of Bubbly Creek. The creek's waters are largely stagnant, having little gravitational flow; the study will look into possibilities, including a meandering stream amid a wetland, to restore an oxygenated system. The actual renovation project is expected to cost $15.4 million. In 2015, the project was stalled, due to contamination discovered in the creek's sediments.
