That's as of the 2010 census. The demographics of EPA have shifted pretty dramatically since then -- Facebook moved into the old Sun campus around 2011, making the area highly desirable for their employees. Combined with the growth of Google (a few exits south on 101) and other tech companies in the area, EPA has seen some significant gentrification. (This is a relatively recent effect, of course; the "residents only" limitations on the Foothills Park are much older.)
