Stream Flow Depletion and Baseline Groundwater-Surface Water Interaction Monitoring of the Ventura River


SCH Number
Public Agency
Upper Ventura River Groundwater Agency
Document Title
Stream Flow Depletion and Baseline Groundwater-Surface Water Interaction Monitoring of the Ventura River
Document Type
NOE - Notice of Exemption
Document Description
The proposed project would include the design, construction, and operation of up to 17 groundwater monitoring well clusters and three stream gauges. The proposed project would address significant and unreasonable depletion of interconnected surface water of the Ventura River within the Upper Ventura River Basin as provided for under the Sustainable Groundwater Management Act, particularly during dry weather conditions when surface water flow that is critical for maintaining essential aquatic habitat for special status species is dependent on groundwater discharge. The proposed project would be an initial step in implementation of the Upper Ventura River Groundwater Agency's forthcoming Groundwater Sustainability Plan, which is currently under development. The monitoring facilities and baseline monitoring will provide data to understand what actions in the region can address stream flows.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Class 3 (15303), Class 4 (15304), and Class 6 (15306)
Reasons for Exemption
The proposed project would involve construction of a limited number of new monitoring wells and stream gauges. Monitoring wells would occupy approximately three square feet at the surface if vaulted individually or approximately 40 square feet at the surface if vaulted as a cluster. Stream gauges would consist of small segments of one-inch steel or PVC housing/standpipe. Therefore, these elements would be classified as small new equipment and facilities, and the Class 3 exemption is applicable. In addition, construction of the proposed project would consist only of minor public alterations in the condition of land and vegetation and would not involve the removal of healthy, mature, scenic trees. Therefore, the Class 4 exemption is applicable. Moreover, the proposed project would involve a monitoring well and stream gauge network to provide data to understand what actions in the region can enhance stream flows and to manage interconnected surface water depletion, evaluate stream flow conditions, and evaluate stream responses to enhancement efforts by all entities in the region. Furthermore, the proposed project would not result in a serious or major disturbance to an environmental resource. Therefore, the Class 6 exemption is applicable.
