Essentially the plan — which has the slightly pared-down name of Downtown Crenshaw — is about building and keeping Black wealth within the community. It calls for reinventing the mall as an “urban village” that would build on some things that already exist and include retail, park space, offices, affordable housing, a boutique hotel, a cultural center and production studios. For the project, Downtown Crenshaw Rising has enlisted outfits such as SmithGroup, an architectural firm that helped design the National Museum of African American History and Culture in Washington, and MASS Design Group, a Boston-based firm that helped design the National Memorial for Peace and Justice in Alabama.
