2012 Wastewater Rate Study

In 2012, the District engaged the services of HF&H Consultants, LLC to provide consulting services for a wastewater rate study. HF&H developed a model that incorporates a wastewater utility cost of service study and produces a rate structure that complies with the substantive and procedural requirements of Proposition 218, particularly its property-related fee section.
