HUD developed the concept of the Continuum of Care in 1995 through its annual competition for homelessness assistance grants. The CoC was envisioned as a local network that plans and coordinates funding for services and housing to assist homeless individuals and families. 

ARCH is the CoC for eight parishes of Louisiana:  Acadia, Evangeline, Iberia, Lafayette, St.  Landry, St. Martin, St. Mary, and Vermilion.
