Aaron Ferguson’s expertise in water law is the result of a unique combination of working on complex water law issues coupled with previous careers as a water supply analyst and a regulatory affairs specialist. He provides a well-rounded vision on the water issues that face his clients.
Aaron helps clients understand and protect their water rights, maximize the value of their water supplies, and achieve their water supply planning objectives. He regularly advises landowners and public agencies with respect to the existence and scope of their water rights and memorializes his findings in water right opinions. Recently, he helped a client challenge a State Water Resources Control Board (State Water Board) Cease and Desist Order determining the client does not possess a riparian right to a specific parcel of land.
Aaron combines his knowledge of water law with his experience in water supply planning to assist clients in the development of water supply plans such as Urban Water Management Plans and Water Supply Assessments consistent with relevant legal requirements. He applies these skills to help clients develop Groundwater Sustainability Plans (GSPs) under the Sustainable Groundwater Management Act (SGMA) and continues to assist these clients with the implementation of their GSPs. He also provides advice to public agencies on Proposition 218 compliance for imposition of water rates. He has advised clients in the development and adoption of groundwater management fees pursuant to the SGMA.
Aaron applies his expertise in water rights law to deliver efficient solutions to complex water resources challenges facing his clients, including negotiating and drafting facility capacity agreements and surface water and groundwater transfer agreements. He also assists clients in developing creative solutions to regulations proposed by administrative agencies, including his current work crafting alternatives to the State Water Board’s flow-based approach to maintaining and improving water quality in the Bay-Delta watershed in what is known as the Healthy Rivers and Landscapes program. He helps clients challenge administrative agency decisions through agency appeals and litigates agency decisions in court. His current work includes litigation contesting bond resolutions for the Delta Conveyance Project (DCP), challenging State Water Project (SWP) contract determinations by the California Department of Water Resources (DWR) and disputing the constitutionality of the State Water Board’s water quality certification fee.
Outside of his law practice, Aaron enjoys spending time with his family, hiking, and skiing.
