Louisville's NuLu air quality reflects the East Market District arts and dining corridor, with vehicle traffic on Market Street and the surrounding rapidly developing mixed residential and commercial character contributing local sources. The flat terrain allows reasonable dispersal, while the neighbourhood's increasing walkability and the arts character maintain moderate Louisville metropolitan readings and NuLu generally tracks at typical inner East Louisville arts corridor levels throughout most of the year.
