If you live around the Civic Plaza, you have a new ANC rep: Angelica Castañon, who works in education policy and advocacy. There was a three way race with Castañon, Jordan Pearlstein and Charles Greene III after the previous commissioner for the area resigned.
The ANC meets monthly to talk about local issues, advise the city council on planning and development in the area, and also make changes or block alcohol license requests. If you’re interested in going, and it’s worth it to get a good sense of what’s happening in your area, meetings are listed here. If you live in southern Columbia Heights (see map) you’re represented by ANC1B, which is here — however, their site is giving me a malware warning.
