New Haven's East Rock air quality benefits from the 425-acre East Rock Park's substantial trap rock ridgeline providing natural filtration and topographic variation. Vehicle traffic on the surrounding Orange Street corridor contributes modest local sources, while the park's elevated rocky ridge and the woodland canopy generally maintain East Rock among New Haven's more pleasant residential environments throughout most of the year.
