It is unrelated to the Lenhardt Creek development, which appears to be in Easley. The nearest neighborhood is Nicholtown - which is still in the process of revitalization, part of which involves this trail. Some parts of the Nicholtown are now not so bad, but you'd need to do careful research before buying.
Other nearby, walkable neighborhoods are Alta Vista and Cleveland Forest, but very pricey.
As an aside, I looked up the
story of Jeanne Lenhardt to see how the bridge got its name. (about halfway down the page).
