Homelessness Response Plan
The City’s response to homelessness is primarily focused on the safety of individuals who live, work, or attend school in Diamond Bar. It is based on the main principles of: (1) acknowledgment that homelessness is a national concern, (2) recognition that homelessness cannot be solved by a single entity; rather, it requires involvement and collaboration among various government, private, nonprofit, service, and faith-based entities, and (3) understanding that not having a home is not a crime.
