A trio of deputies from the Environmental Protection Agency, Housing and Urban Development and the Department of Transportation toured sites along Cincinnati's proposed streetcar route Thursday. They're checking out sustainability projects such as rain gardens and housing developments.

The Western Wildlife Corridor is working hard to improve the Ohio River Valley, specifically on the western side of Hamilton County. Stretching from Mill Creek near downtown to the Great Miami River bordering Indiana, one of the primary threats, according to WWC President Tim Sisson, is the prevalence of invasive plant species. Mark Perzel talks with Mr. Sisson about this and other threats, and how the WWC is working to improve this area of the county.
