Chicago, Illinois

  • V3 Companies worked with the Park District to develop habitat restoration and environmental remediation plans for the ecological revitalization of the site. Public workshops with the local residents and schools were conducted throughout the planning and design process.

  • Challenges include practical habitat and native plant establishment in highly degraded environments, while mitigating the human health and ecotoxicological risks posed by site contaminants, the presence of sensitive species and planned eco-recreational use.

  • Project objectives included restoration and enhancement of the natural areas in addition to the creation of six acres of wet prairie and the development of a public park and trail system. The proposed trail system links the subject site to a larger regional trail network encompassing the Lake Calumet region.

  • In addition to the ecological restoration, V3 designed access to the site and a parking lot. The site will be graded for future trails.

  • Primary contaminants of concern at the site include heavy metals, polynuclear aromatic hydrocarbons and residual pesticides (DDT, DDE, DDD).

  • Field investigations included the environmental sampling of site soils, wetland sediments, groundwater, primary forage plants and fauna within the food chain.

  • Advanced human health and ecological risk assessments were performed in accordance with the Calumet Area Ecotoxicology Protocol and Illinois EPA risk-based cleanup methods.

  • Native plant selection for the habitat restoration included avoiding the use of phyto-accumulating plants and eradicating known accumulators that currently existing at the site.

  • Design plans balance practical soil rehabilitation in conjunction with  phyto and traditional remediation while ensuring that the restoration protects the public and the sensitive species using restored habitats.
