ECONOMIC AND ENVIRONMENTAL IMPACTS OF STORMWATER MANAGEMENT : Case study: Cost-effectiveness evaluation of Proposition O projects

Stormwater Management (SWM) or Best management practices (BMPs) treat the stormwater runoff that carries pollutants. Pollutants in the waters and in the stormwater, negatively impact the environment, the ecology, and natural resources. Stormwater Control Measures (SCM) are used in different projects...
