California (and much of the West Coast) has introduced stormwater quality requirements on large new construction projects, commonly referred to as C.3 Stormwater guidance. This requires that all water coming off constructed environments be filtered through bioswales and bioretention areas to improve water quality. You’ve probably seen these kinds of filtering areas within parking lots and around buildings. You can learn more about the requirements at this website.
