City Warns Damen Silos Site Owner for Stormwater and Zoning Violations

Friends of the Chicago River commends the City of Chicago for taking action against the owner of the former Damen Silos site along the South Branch of the Chicago River, reinforcing the importance of taking action against irresponsible development along the river system. In June, the city issued the violation letter to the property’s owner after determining that a parking lot had been constructed without first submitting a required stormwater management plan, according to the Chicago Sun-Times. Failure to submit a stormwater management plan is a violation of Chicago's stormwater ordinance, which is designed to reduce flooding, improve water quality, and protect the health of local waterways. The city’s letter also cites additional zoning ordinance violations. The owner of the site must now submit a stormwater plan.

Responsible stormwater management is a critical component of protecting the Chicago-Calumet River system. Without proper planning and infrastructure, rainwater can carry pollutants such as oil, sediment, heavy metals, and trash directly into the river while increasing localized flooding. As climate change brings more frequent and intense rainstorms to the region, ensuring that new development complies with stormwater regulations is more important than ever.

"The city’s action sends an important message that protecting our rivers and communities requires strong enforcement of environmental and stormwater regulations," said Margaret Frisbie, executive director of Friends of the Chicago River. “Every development across the watershed must manage stormwater responsibly and comply with the laws, regulations, and ordinances that safeguard water quality, reduce flooding, and support a healthier, more resilient river system.”

If anyone suspects violations at a development, they must report it to the city by calling 311 so that steps can be taken to enforce compliance.
