Water Quality

Addressing stormwater quality is equally as important as dealing with the quantity of wet weather flows. Water flows over streets, parking lots, and other impervious areas and collects oils, dirt, and other pollutants in the process. Our goal is to protect the environment for this generation and generations to come. Donohue is experienced in developing Stormwater Quality Management Plans, helping communities meet their MS4 permitting requirements, and identifying green, sustainable infrastructure improvements that help to reduce pollutant pressures on our waterways.
