We thought that we would visit the DC Homeland Security and Emergency Management Agency in Anacostia. This would co-ordinate any large scale disasters on the level of the Tsunami that hit Japan, or of some large scale alert relating to Nuclear incidents. Approaching the UCC (see below) to confirm we had the right building we were advised that this 'may or may not' be the building we were looking for, although it was on the sign outside, and were then advised that we most definitely could not take photographs of the building from there, even though it is quite clear to see if you go on Google Maps Street View. So we moved down a little and waited to see what happened next.

Officially speaking:
The UCC was built by the District’s Office of the Chief Technology Officer (OCTO) to consolidate the command and control functions of the city’s emergency and non-emergency citywide call center, to help improve customer service through a consolidated citywide constituent call center, and to serve as a citywide emergency management center. It houses the DC Office of Unified Communications (OUC) and the DC Homeland Security and Emergency Management Agency (HSEMA).
