Like Los Alamos and Oak Ridge, Richland was a gated community with restricted access, but it looked more like a typical wartime American boomtown: the military profile was lower, and physical security elements like high fences, towers, and guard dogs were less evident.
Ligesom Los Alamos og Oak Ridge var Richland et indhegnet samfund med begrænset adgang, men den lignede i højere grad en typisk boomende amerikansk by under krigen: den militære tilstedeværelse var mindre og den fysiske sikkerhed i form af høje hegn, tårne og vagthunde var knap så åbenlys.
