Best Practices for Healing Historical Wounds?

Here in Oklahoma City, the government has historically used eminent domain to destroy low income neighborhoods and convert the land to the uses of non-low income people (e.g., freeways to bring commuters from upscale suburbs to downtown, upscale housing and shopping, etc.). This has harmed many people and created lingering sentiments of resentment, fear, and hostility. I am wondering if there are other areas that have faced similar situations that have developed ways to deal with these externalities of urban renewal, and if so, what would those best practices be?
