Stormwater Management

Stormwater is defined as “stormwater runoff, snow melt runoff, and surface runoff and drainage” [40 CFR 122.26(b)(13)]. Stormwater is a resource and asset for California that should be managed in a sustainable manner.

Pollutants of concern in urban runoff include sediments, solids, nutrients, pathogens, oxygen-demanding substances, petroleum hydrocarbons, heavy metals, floatables, polycyclic aromatic hydrocarbons (PAHs), trash, pesticides and herbicides. In accordance with section 402(p) of the Federal Clean Water Pollution Control Act (Clean Water Act), National Pollutant Discharge Elimination System (NPDES) permits are required for discharges from municipal stormwater system facilities and non-traditional facilities such as railroad tracks and stations. The Authority’s goal for stormwater management is to design, construct, and operate facilities in compliance with requirements to control pollutants and protect water quality resources in a sustainable manner.
