I had multiple family members involved in a massive fire in my area a few years back. Seeing them go through it, I can tell you one of the best ways, that assures people that actually need it get it, and that it is not bums taking advantage of charities. What a lot of people did in my region was called local churchs, gave their name and number to pass onto the many families that were homeless, and ask them to either contact them or to meet them somewhere at a specific time. They then handed the money/clothes/food/school supplies directly. There was also multiple cases that I know of where through this they set up families in travel trailers at the local parkgrounds for temporary housing through the churchs. This way you know 100% of the money is going to directly to the needy and nothing gets skimmed off.
