New Orleans' Marigny and Bywater air quality reflects the Creole cottage neighbourhoods downstream from the French Quarter, with vehicle traffic on St. Claude Avenue and the surrounding mixed residential and arts character contributing local sources. The Mississippi River provides limited ventilation, while the neighbourhood's walkable character and the surrounding residential density maintain moderate New Orleans metropolitan readings and the area generally tracks at typical inner New Orleans neighbourhood levels throughout the year.
