Dozens of local community service organizations, like the Rotary Club, that help with community problems. Everyone who joins will be "secular", in other words, an atheist. It should look caring, community, modern, warm, friendly, helpful, and non-religious.
Please use symbolism that shows community, such as a group of figures, a group of hands, a group of arms and hands, or anything else you can think of that shows friendly, warm, community, helping people.
Unfortunately a lot of community logos (see my examples) look really dorky, overly warm and generic. I would love to find some original concepts that I can't find elsewhere.
Please don't use the US Capitol building in the logo, because this logo is meant to be used anywhere in the United States. The US Capitol building is not in every city in the United States.
