Horizon Water and Environment (Horizon) provides clients with expert services in preparing Water Supply Assessments per requirements of Senate Bills (SB) 610 and 221 and processing appropriative water right permits with the State Water Resource Control Board (SWRCB), Division of Water Rights.

SB 610 and 221 Water Supply Assessments require projects that demand a significant quantity of new water to assess the availability of supplies.  Horizon staff are skilled at preparing Water Supply Assessments including collecting data and evaluating water supply sources, existing entitlements, water rights allotments, production amounts, existing demands, and infrastructure needs. Based on this information, Horizon evaluates current and projected water availability and determines the sufficiency of the supply to meet projected demand.  Where supplies are insufficient to meet demands, Horizon develops practical mitigation measures. Horizon is adept at 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.

Horizon staff have expertise in obtaining and maintaining appropriative water right permits in California. Horizon works with clients and the Division of Water Rights to determine the information and steps needed to process water right applications and petitions, or take an existing permit to license. Typical requirements of water rights processing may include obtaining regulatory permits, California Environmental Quality Act (CEQA) compliance, preparing Public Trust Resources Analysis, and/or resolving protests on applications or petitions. Horizon provides clients with the services needed to accomplish each step in the water rights process. Horizon also assists clients in maintain existing water rights by conducting annual water supply accounting and reporting to the Division of Water Rights.

In addition to our expertise with water supply assessments and water rights, we assist our clients with a variety of water resource planning including developing guidance documents for water conservation, water recycling/reuse, and water smart development.  We have helped regions develop Integrated Regional Water Management (IRWM) plans and have also assisted organization with seeking grant funding through the State IRWM program.   We are skilled at supporting Counties and Cities with water and stream focused conservation elements and providing policy evaluations for developing general or specific plans.  Horizon also provides our clients with CEQA and regulatory support for these planning processes.
