Meeting Obj ectives

 Help keep you informed about the

S ustainable Groundwater Management Act

 Understand your needs and priorities  Open lines of communication  Build common goals for the Bedford

Coldwater S ubbasin

Introduction to the S ustainable Groundwater Management Act

The S ustainable Groundwater Management Act (S GMA)

 S

ustainable Groundwater Management Act (S GMA) was passed by the California legislature in 2014

 Created a framework for sustainable groundwater

management in California

 Sustainable Groundwater Management =

“ Management and use of groundwat er in a manner t hat can be maint ained during t he planning and implement at ion horizon wit hout causing undesirable result s.”

“ … groundwat er management in California is best accomplished locally.” – Governor Jerry Brown, S ept ember 2014

S GMA

 Requires the formation of Groundwater

S ustainability Agencies (GS As) – generally agencies

• verlying the groundwater basin

 GS

As are responsible for preparing Groundwater S ustainability Plans (GS Ps) and be submitted by:

 January 2020 for critically over drafted basins  January 2022 for remaining high and medium

priority basins

 Creates a single sustainability goal for the basin or

subbasin

 Achieved within 20 years of GS

P implementation

 Maintained without causing undesirable results

S GMA

Two main goals to promote basin health:

• 1. S

top overdraft by “ balancing the water budget”

• 2. Achieve sustainable yield and avoid

six undesirable results

Lowering GW Levels Reduction

• f Storage

Basin Prioritization

 Four groundwater basin categories:

High, medium, low, and very low

 Based on components in California

Water Code S ection 10933(b)

 Population overlying basin or

subbasin

 Number of wells that draw from the

basin

 Irrigated acreage overlying the basin  Reliance on groundwater for primary

source of water

Groundwater S ustainability Agencies

 Allows for intervention by the S

tate Water Resources Control Board (S WRCB) at points throughout the process of achieving sustainable groundwater management

 S

GMA Required Groundwater S ustainability Agencies (GS As) be formed

 Expanded the role of DWR to support local

implementation of sustainable groundwater management by GS As

Powers and Authority of a GS A



Adopt rules, regulations, ordinances and resolutions to achieve groundwater sustainability



Conduct investigations for the purpose of:

 Determining the need for groundwater management  Preparing and adopting a GS

P and implementing rules and regulations

 Proposing and updating fees  Monitor compliance and enforcement  Inspection of property or facilities to ascertain compliance



Require registration of a groundwater extraction facility



Require measurement and recording of groundwater extraction (costs borne by owner or operator)



Require groundwater extraction facilities to file an annual report

Powers and Authority of a GS A (continued)



Acquire land, water rights, rights-of-way, structures, or

• ther property



Appropriate and acquire surface or groundwater (or rights thereof)



Transport, reclaim, purify, desalinate or treat wastewater or polluted water



Additional authorities

 Regulate or limit groundwater extractions  Limit construction of new wells, or reactivation of older

wells

 Authorize transfers and carryover of groundwater

extraction allocations

Groundwater S ustainability Plan

 GSP development must be a transparent and

• pen process encouraging stakeholder and

public input

 Establish minimum thresholds for each

sustainability indicator to avoid undesirable results

Bedford Coldwater Groundwater S ustainability Authority

Bedford Coldwater Groundwater S ustainability Authority



Joint Powers Authority (JP A) formed by three local agencies in February 2017 for management of the S ubbasin

 City of Corona  Elsinore Valley Municipal Water District  Temescal Valley Water District

City of Corona TVWD

Jacque Casillas, Director Phil Williams, Vice-Chairman

EVMWD

Paul Rodriguez, Chairman



JP A signed a resolution in March 2017 to become the GS A for the S ubbasin



Governed by a representative Board member from each agency

Bedford Coldwater S ubbasin Prioritization

 Bedford Coldwater

S ubbasin classified as a very low priorit y subbasin

 Groundwater use

<9,500 acre-feet per year and no documented impacts to the subbasin

DWR SGMA Basin Prioritization Tool

2017 Prop 1 S GWP Grant

 BCGS

A was awarded funding by the Department of Water Resources (DWR) of the S tate of California through the Proposition 1 S ustainable Groundwater Planning (S GWP) Grant

 S

GWP Grant provides funding to assist in financing the planning and/ or selected proj ect activities that will improve sustainable groundwater management

 BCGS

A submits quarterly progress reports to DWR under the conditions of the grant

GS P Development Timeline

July 2019

• Begin Draft GSP development

July 2020

• Draft GSP available for public review

December 2020

• Final Draft GSP submitted to DWR

Open Discussion

 Who are the private groundwater users in the

S ubbasin?

 Rough estimate of volume used  Use of groundwater  Groundwater quality  Concerns?

 Who has concerns about the current groundwater

conditions or elements of the GS P?

 What specific subj ect matter should be discussed

in the GS P?
