Horizon provides clients with expert services for obtaining and maintaining appropriative water right permits in California. We work with clients and the State Water Resources Control Board (SWRCB), Division of Water Rights, to conduct the necessary due diligence to process water right applications and change petitions, or to take an existing permit to license. Typical requirements of water rights processing may include regulatory permitting, CEQA compliance, Water Availability Analyses, Public Trust Resources Analyses, and/or resolving protests on applications or petitions. Our experience includes topics such as place of use, purpose of use, point of diversion or re-diversion, instream beneficial uses, water transfers, and considerations related to other legal users of water and the public trust. Horizon also assists clients in maintaining existing water rights by conducting annual water supply accounting and reporting to the Division of Water Rights.
Horizon also prepares Water Supply Assessments per requirements of Senate Bills 610 and 221. These laws require that projects demanding a significant quantity of new water assess the availability of supplies, as part of the CEQA process or otherwise. Our experience includes evaluating water supply sources, existing entitlements, water rights allotments, production amounts, existing demands, and infrastructure needs. Based on this information, Horizon assesses current and projected water availability and determines the sufficiency of the supply to meet projected demand. Where supplies are insufficient to meet demands, we assist our clients in developing practical mitigation measures. Horizon has experience assessing a wide range of water supply sources, including surface water, groundwater, State Water Project, supplies from wholesale water suppliers, and other contracted sources of supply.
