- MITIGATED NEGATIVE DECLARATION FOR THE EXPANSION OF DISTRICT DISTRIBUTION SYSTEM PIPELINES INTO GROUNDWATER SERVICE AREA LANDS PROJE
- The proposed Project is for the construction of up to 44 miles of pipelines, manholes and turnouts within AEWSD. Assuming a maximum of 50’ width for possible ground disturbance along the proposed pipeline construction, the Area of Potential Effect (APE) is approximately 267-acres. The Project goal is to deliver wet-period surface water to landowners who would otherwise pump groundwater in the portions of the GWSA. The proposed pipelines will be operated when excess surface water is available (approximately every three years) and/or when water transfers are scheduled. The proposed pipelines will be mainly low-head gravity distribution pipelines ranging from 12” to 72” in diameter. The largest pipe sizes would be proportionally short distances near the heads of the branching gravity pipeline networks serving the various private agricultural fields and orchards in the APE. The proposed pipeline sizes and capacities will vary depending upon the number of acres served. Pipeline sizing will follow the conservative value of approximately eight gallons per minute per acre and/or the AEWSD Lateral Demand Sizing Criteria. The proposed pipelines will commence from various existing AEWSD facilities, such as the Forrest Frick Discharge Pipeline, North Canal, South Canal, or other smaller lateral pipelines. A 0.75-mile open canal is also proposed from the existing Tejon Spreading Works.
