Advisory Neighborhood Commission 4D represents the Petworth neighborhood. The Advisory Neighborhood Commissions (ANC) consider a wide range of policies and programs affecting their neighborhoods, including traffic, parking, recreation, street improvements, liquor licenses, zoning, economic development, police protection, sanitation and trash collection and the District's annual budget. In each of these areas, the intent of the ANC legislation is to ensure input from an advisory board that is made up of the residents of the neighborhoods who are directly affected by government action. The ANCs are the body of government with the closest official ties to the people in a neighborhood. The ANCs present their positions and recommendations on issues to various District government agencies, the Executive Branch and the DC Council. They also present testimony to independent agencies, boards and commissions, usually under rules of procedure specific to those entities. By law, the ANCs may also present their positions to federal agencies.
