Proposition 218 Election to Fund Local Groundwater Management Passes

Landowners residing in the South Fork Kings GSA voted in favor of a $9.80 per acre assessment to cover the costs associated with implementing the State’s groundwater law, the Sustainable Groundwater Management Act (SGMA). Following the close of the Proposition 218 public hearing on June 21st, the South Fork Kings GSA Board tabulated and certified the results of the election. The assessment was favored by 74% of received votes. A majority of received votes was needed to pass the assessment; votes were weighted be acreage.

The Board approved and set a rate of $9.80/acre for the fiscal year 2018-19. Each year, the Board will set a rate not to exceed the $9.80/acre maximum for the five-year lifespan of the assessment. All landowners within the boundaries of the South Fork Kings GSA, excluding those residing in the City of Lemoore, will be assessed the rate via Kings County tax rolls beginning fiscal year 2018-19. The City of Lemoore has entered into a cost sharing agreement on behalf of all property in the City limits and has incorporated ongoing payments into their existing rate structure.

The Board is committed to keeping local jurisdiction over groundwater management under SGMA, where landowner dollars are used more efficiently and beneficially. With funding from the election, the GSA is equipped to meet the nearest deadline: completion of a Groundwater Sustainability Plan (GSP) by January 2020.

Proposition 218 is a Constitutional Initiative approved by the voters of California in November 1996. It requires new or increased fees and assessments be approved by affected landowners.

An Engineer’s Report was conducted to set the $9.80/acre assessment rate. The Report calculates the equitable distribution of the benefit derived from each parcel within the agency upon which assessment will be levied. The Engineer’s Report discusses benefits of the Agency’s organization, proposed actions, and services provided by the South Fork Kings Groundwater Sustainability Agency.

Board Approves Engineer’s Report, Moves Forward with Prop 218 Assessment

At the March 15th board meeting, South Fork Kings Groundwater Sustainability Agency (GSA) board members approved the Engineer’s Report prepared by Geosyntec Consultants. The Engineer’s Report was presented by the South Fork Kings GSA technical consultant, Amer Hussain of Geosyntec Consultants. Adoption of the Report signals Board approval for a Proposition 218 Election, a Constitutional Initiative passed by CA voters in 1996 that requires all new or increased assessments be approved by affected landowners. All landowners within the boundaries of the South Fork Kings GSA will be asked to vote on the newly proposed assessment. Its purpose is to fund the local GSA’s efforts to comply with the unfunded CA state law, the Sustainable Groundwater Management Act (SGMA).

The Engineer’s Report outlines the South Fork Kings GSA’s five-year projected operating costs and expenses associated with the development and initial implementation of a Groundwater Sustainability Plan as required by SGMA, ongoing administration, technical assessments, and recovery startup costs incurred by the South Fork Kings member agencies.

Additional components of the report include background information on the GSA, summary of GSA operations, a description of the proposed assessment, a determination of benefits derived from the assessment, and procedures to implement the assessment. Based on the model developed, the maximum annual rate proposed for assessment is $9.80 per acre for the five-year life of the proposed assessment, subject to annual review and determination by the Board. The assessment rate levied cannot exceed $9.80 without another election for voter approval. You can view the full Engineer’s Report here: Engineer’s Report. 

If the South Fork Kings GSA is unable to fund its efforts to comply with SGMA, the State will intervene. The Board seeks to avoid costly State Intervention and keep SGMA implementation at the local level. To find more information regarding the assessment, visit our Prop 218 page.

The Model, the Data and Groundwater Sustainability

At the February 1 Board meeting, South Fork Kings Groundwater Sustainability Agency (GSA) technical consultant, Bob Anderson of Geosyntec Consultants, covered what a model can and cannot do and the importance of data and how they will be used in determining groundwater sustainability in the Tulare Lake Subbasin.

To guide regional activities necessary to implementing the Sustainable Groundwater Management Act of 2014 (SGMA), a Groundwater Sustainability Plan (GSP) will be prepared to cover the entire Tulare Lake Subbasin (see diagram below). The South Fork Kings GSA is one of six GSAs within the subbasin that must coordinate their planning to complete a shared GSP, but coordination is not limited to the six GSAs.

The Tulare Lake Subbasin is delineated by a political rather than scientific boundary. The geological or physical boundary of the principal aquifer, the San Joaquin Valley Basin, is bound on the east by the Sierra Nevada, to the west by the Coastal Range and north and south by Sacramento and the Tehachapi Mountains. The Tulare Lake Subbasin is 1 of 16 subbasins within very large (9-million acre/14,000 sq/mi) San Joaquin Valley Basin.

In order to understand and address water flow between political boundaries SGMA also requires that GSAs in each subbasin coordinate with GSAs in neighboring subbasins. The visual below shows the South Fork Kings GSA, the five other GSAs in the Tulare Lake Subbasin and their neighboring subbasins.

The core element for the GSP is its water budget, which describes the amount of water coming into a subbasin versus the amount going out. A good comparison for understanding how a water budget works is to think of it as a bank account. SGMA requires that a subbasin identify impacts of over-pumping and then take corrective actions that will result in long-term sustainability. It is up to the South Fork Kings GSA Board to define what “sustainable” means within its jurisdiction and in the entire Tulare Lake Subbasin through coordination with neighboring GSAs.

A computer model is a tool that breaks down an area into thousands of individual water balance cubes that when combined can make very complex groundwater flow and water balance calculations.

The computer model for the Tulare Lake Subbasin will assess the six undesirable results as defined by SGMA. Defining these six undesirable results for the South Fork Kings will be the roadmap to sustainability for the groundwater subbasin. The diagram below illustrates how a model computes one undesirable result, the chronic lowering of groundwater levels.

Models need data. Data is the best indication of what is going on. Where data does not exist, assumptions must be made and therefore the more data there is the better the analysis will be. Some data is already available through sources like the Department of Water Resources (DWR) that has collected depth to groundwater data for years.

Other important data needed include surface water diversions and cropping patterns. In the absence of measured groundwater well pumping rates, the Tulare Lake Subbasin model will back its way into a groundwater pumping estimate using cropping pattern data coupled with irrigation estimates and measured surface water diversions.

The model and data are a couple of the pieces needed to complete the GSP by the State’s deadline of January 2020. 

Board Approves Data Sharing Agreements with North Fork Kings GSA, Westlands Water District

The Board approved entering into two agreements, one with the Westlands Water District and the second with the North Fork Kings Groundwater Sustainability Agency to share relevant data and to establish a set of common assumptions on groundwater conditions within five (5) miles of the boundary between the South Fork Kings GSA and these two neighboring agencies. The agreements support the effort to coordinate planning efforts with neighboring GSAs and subbasins.

Board Approves Preparation of Engineering Report for 218 Election

At a regular meeting held on September 21st, the South Fork Kings GSA Board approved a task order with Geosyntec Consultants, Inc. to prepare an engineering report  and to conduct a Prop 218 assessment election. The engineering report will include an analysis for the costs to prepare a Groundwater Sustainability Plan, costs for ongoing administration, and the recovery of startup costs incurred by the South Fork Kings member agencies. Components of the report include background information on the GSA, summary of GSA operations, a description of the proposed assessment, a determination of benefits derived from the assessment, and procedures to implement the assessment. The proposed timeline to complete the engineering report and conduct a 218 election is April 2018. The estimated cost to complete the entire process is $29,560.

In other business, the Board approved a task order in the amount of $18,000 with Geosyntec Consultants to conduct initial data assessment and modeling review along with reviewing the proposed scope of work to be included in a planning grant application for Proposition 1 funding.
