Environmental Stewardship

The Eastern Corridor region contains a rich mix of man-made and natural resources. Variable topography, high quality streams, floodplain and groundwater resources, and developed communities all contribute to the aesthetic and environmentally important context of this part of the Cincinnati metropolitan area.

Sensitive resources that require special consideration during project development include:

  • The Little Miami River and other surface streams
  • Wetlands
  • Floodplains
  • Aquifers
  • Plant and wildlife resources
  • Threatened and endangered species habitat
  • Cultural historic and archaeological resources
  • Air quality
  • Noise

Important community and environmental resources identified during the Tier 1 study are listed below (click each to see associated graphics). Some of these resources have experienced change since this initial work was completed and information is updated and evaluated Eastern Corridor improvements continue to be planned.

Drainage Areas
FEMA Floodplains
Parks and Greenspace
National Register of Historic Places
Archaeology Sensitivity
Potential Hazardous Materials Concerns


A green infrastructure framework for the Eastern Corridor, initially focused on the Little Miami River valley, was developed and presented in the Green Infrastructure Master Plan in the Eastern Corridor Transportation Investment Area. Through local landowner and stakeholder input, this planning effort identified community and resource priorities as well as mitigation and preservation opportunities in the area. This plan continues to be used as resource when planning Eastern Corridor transportation improvements.
