New Haven's Westville air quality reflects the historic residential neighbourhood adjacent to West River Memorial Park, with vehicle traffic on Whalley Avenue and the surrounding residential and arts character contributing local sources. The West River corridor provides limited natural ventilation, while the neighbourhood's tree-lined character and the walkable village scale generally maintain moderate New Haven metropolitan readings throughout most of the year.
