As part of the restoration project, LA County Public Works operated an air quality monitoring network that collected continuous data on ambient air quality and meteorological conditions at the Devil’s Gate Reservoir Restoration project site. LA County installed six monitoring stations strategically located within and surrounding the restoration project site for compliance purposes and to monitor potential air quality impacts resulting from the restoration project.

Tetra Tech created an application that automatically pulls data from the Aeroqual monitor cloud database into a database and calculates the Air Quality Index (AQI). Tetra Tech created a website for the public viewing of current and historical air quality readings at the monitoring stations as well as general information about the air quality monitoring stations.

The air quality monitoring data collected from the monitoring stations was used to better manage and provide feedback to LA County Public Works to implement best management practices and emission mitigation measures to reduce potential negative environmental and public health impacts by the restoration project.
