Use Arvin’s geography to define the intake boundary
Those are different operating choices. Arvin is recorded within Kern County, so the intake should not silently treat the city, county and state as interchangeable. A visitor’s location can be one review point, but it should not become an unsupported assumption about eligibility or case value.
Recommended approach
Write the geographic rule your team actually uses: Arvin only, Kern County, California, or another stated service area. Then decide what should happen when a visitor is outside it. The review should cover an appropriate explanation, an internal handoff or a decline path rather than leaving ownership unclear.
