Louisville's Old Louisville air quality reflects the Victorian residential neighbourhood, with vehicle traffic on the surrounding arterials and the concentrated Central Park character contributing local sources. The Victorian architecture's dense street character and the Central Park greenspace provide limited buffering, while the flat terrain allows reasonable dispersal and Old Louisville generally maintains moderate Louisville metropolitan readings throughout most of the year.
