Stormwater infrastructure in cities is highly visible and serves to mitigate flooding and reduce pollution that reaches local waterbodies. Being so visible, it might be reasonable to assume that stormwater is adequately funded both in infrastructure and water quality management. Yet, stormwater infrastructure and water quality improvement are notoriously difficult to fund. Paying for stormwater quality improvements in California has been a multi-decade challenge due to the industry’s relatively recent emergence during a time of fiscal constraints on local governments.
