However, even as late as 2010, most of the core area tended to be empty of pedestrian foot traffic at night, except for streets immediately around theaters and restaurants. Downtown D.C. has been adding residents, however, and pedestrian traffic at night is increasing. In 1990, the area had about 4,000 residents, but this had increased to 8,449 by 2010. Such increases appear small, but are more significant than they seem because the city's height restrictions limit population density. The completion of the $950 million CityCenterDC project in late 2013 is estimated to add another 1,000 or more residents. One exception to the low nighttime foot traffic is Gallery Place. Large crowds gather day and night at Gallery Place, especially after sporting events at the Capital One Arena. Crime and street brawls in the area skyrocketed in the area and its adjacent Gallery Place Metro station between 2008 and 2010, primarily due to the large groups of teenagers (from throughout the metropolitan region) gathering there.
