About OpenANC

OpenANC is an open database of Washington, DC Advisory Neighborhood Commission districts, commissioners, and candidates.

OpenANC is a non-official, non-commercial, non-partisan public resource. It was created to provide voters and candidates with more information about ANC districts with the goal of lowering the barriers to participation in local government.

What's an ANC?

Advisory Neighborhood Commissions are local government organizations in Washington, DC.

From Wikipedia: "ANCs 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. Commissioners serve two-year terms and receive no salary, but commissions do receive funds for the general purpose of improving their area and hiring staff."

DC has 40 Advisory Neighborhood Commissions. Each commission consists of 2 to 12 commissioners who represent single member districts (SMDs). Each SMD contains about 2,000 residents. There are 296 SMDs in DC.
