MITIGATED NEGATIVE DECLARATION FOR THE EXPANSION OF DISTRICT DISTRIBUTION SYSTEM PIPELINES INTO GROUNDWATER SERVICE AREA LANDS PROJE
MND - Mitigated Negative Declaration
Present Land Use
The Project area is surrounded by agricultural lands, most of which is currently in production. The vast majority of proposed pipeline alignments will be installed on AEWSD property, private agricultural property parallel to existing public county road right of way or along existing private dirt farm roads between fields/orchards. A small portion of the Project area is within the City of Arvin city limits. This portion of the Project is surrounded by agricultural or vacant lands, with a residential neighborhood to the north.
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.
The Project site encompasses a lot of AEWSD's boundary and extends approximately 16 miles north/south and is surrounded by agricultural lands, most of which is currently in production. To the South is David Road, North is Muller Road. East is Camanche Drive. West is Highway 184. The town of Arvin sits in the middle with Lamont to the West.
