B. Description of Proposed Boundary Modification

1. Short Description

   Request a jurisdictional internal modification to the Westside Subbasin Boundary, 5-22.09.
2. Type of basin boundary revision

   • Jurisdiction Internal
3. Provide a narrative overview of the boundary modification request and how the resulting modification would affect likelihood of sustainable management.

   The District's request is a jurisdictional internal modification. Westlands Water District (District) is requesting to modify the San Joaquin Valley Groundwater Basin's Westside Subbasin Boundary, 5-22.09, to follow the District's legal jurisdictional boundary last revised in 2006. The 2006 revision included the Broadview Water District (BWD) following annexation into Westlands. The only exceptions to following the District's jurisdictional boundary are the Naval Air Station Lemoore's (NASL) property and the north-west perimeter of the subbasin boundary, which will follow the Coastal Range. The District is requesting that all of NASL property be included in the Westside Subbasin. The District is not proposing to modify the existing north-west perimeter of the subbasin boundary that is shared with the Coastal Range as described in the Bulletin 118- 2006 update of the Westside Subbasin description. The aforementioned Westside Basin Boundary Modification will affect Delta-Mendota (5-22.07), Kings (5-22.08), Tulare Lake (5-22.12) and Pleasant Valley (5-22.10) Subbasins. Through the District's modification request we anticipate achieving sustainability through the implementation of a Groundwater Sustainability Plan (GSP). The District is developing a groundwater model to determine the subbasin's sustainable yield and to promote sustainable management of the Westside Subbasin. This basin boundary request is specifically limited to our jurisdictional boundary, to strengthen the District's local control and management of the Westside Subbasin. The District already has procedures in place to monitor groundwater extractions and approving our request to incorporate BWD and NASL into the Westside Subbasin simplifies its efforts to comply with the requirements of the Sustainable Groundwater Management Act (SGMA).

6. Any information, if necessary, to enable DWR to satisfy the requirements of a responsible agency pursuant to the California Environmental Quality Act.

Westlands Water District request to modify the Westside Subbasin boundary is not a project because the decision to adjust the boundary is within DWR's authority. Additionally, per CEQA §15060 (c) the District's request does not exercise discretionary power by a public agency, result in foreseeable indirect physical change in the environment and is not a project as defined in CEQA §15378.

E. General Information

1. Describe the lateral boundaries of the alluvial aquifer or aquifers that form the groundwater basin and the definable bottom of the basin. The description must be in terms that are clear, definite, and sufficiently detailed to allow an authoritative map of the proposed basin boundaries to be plotted using the given description.

F. Notice and Consultation

1. List all local agencies and public water systems affected by the basin(s) modification request.

Naval Air Station Lemoore, San Luis Water District, Empire West Irrigation District, Tulare Lake Basin Water Storage District, Kings River Conservation District, City of Mendota, City of Huron, San Luis Delta-Mendota Water Authority, Fresno County, Kings County, Tranquillity Irrigation District, James Irrigation District, Pleasant Valley Water District and San Joaquin River Exchange Contractors .

2. Explain the methods used to identify interested local agencies and public water systems in the affected basin(s):

Extensive research and analysis was performed in order to identify all local agencies and public water systems. Geographic information systems (GIS) source files were acquired from numerous organizations including California Department of Conservation, California Department of Water Resources, Fresno County, Kings County, Kings River Conservation District, United States Bureau of Reclamation, United States Census Bureau, and United States Geological Survey. GIS files from the aforementioned agencies established counties, cities, communities, groundwater basins/subbasins, water districts, hydrologic regions, and geological surveys. The GIS files were utilized to determine the existing Bulletin 118 Westside Subbasin boundary compared to Westlands Water District's jurisdictional boundary. The areas that deviated from the proposed Westside Subbasin Boundary identified the affected agencies from our modification request.

3. Provide information regarding the nature of consultations with affected or interested agencies. Attach and cite any copies of correspondences with local agencies and public water systems and/or any other persons or entities consulted.

4. Discuss potential impacts to state programs resulting from the proposed boundary modification, including, but not limited to, the California Statewide Groundwater Elevation Monitoring (CASGEM), Groundwater Management Plans developed pursuant to AB 3030, Groundwater Sustainability Plans developed pursuant to the Sustainable Groundwater Management Act, any applicable state or regional board plans, and other water management and land use programs.

Westlands Water District does not anticipate any impacts to the above mentioned programs. Westlands expects that these programs will be strengthened with the proposed boundary change because areas that are not currently included in our CASGEM program or groundwater management plans will now be included.

Significant geologic and hydrologic features and conditions of the principle aquifer units, as appropriate, including information regarding the confined or unconfined nature of the aquifer, facies changes, truncation of units, the presence of faults or folds that impede groundwater flow, or other groundwater flow restricting features.
   4. Key surface water bodies, groundwater divides and significant recharge sources.
3. Recharge and discharge areas within the basin.
4. Definable bottom of the basin or subbasin.
