Measuring Equipment ID: serial number or identifier of measuring equipment Disinfect and rinse that part of tape that was submerged below water. Dry tape and rewind.

Check circuitry of electrical tape before lowering the probe into the well by dipping probe into tap water.

Make all readings using the same indicator for consistency (light intensity or sound).

Lower electrode probe slowly into the well until the indicator shows that the circuit is closed and contact with the water surface is made. Place the nail of the index finger on the insulated wire at the MP (Measuring Point) and read the depth-to-water.

Record time of measurement. Record depth to water in the row “Measurement (feet)”. If the tape has been repaired and spliced or has a calibration correction, subtract the “Tape Correction” value from the “Measurement” value and record the difference in the row “Water Level below MP”.

Pull the tape up and make a check measurement by repeating steps 3-4. Record the check measurement in column 2. If check measurement does not agree with the original measurement within 0.02 foot, continue to make measurements until the reason of lack of agreement is determined or the results are shown to be reliable. If more than 2 measurements are made, use best judgment to select measurement most representative of field conditions.

Purging Equipment ID/description: serial number or identifier of measuring equipment The Chain-of-Custory form should be filled out as the sample is collected and preserved.

If the well has a dedicated pump and it is operating, ensure that it has been operating consistently and at least three (3) casing volumes have been pumped. If not, note pumping rate and time to purge 3 casing volumes before collecting representative samples.

Measure and record water quality parameters through purging process.

If the well does not have a dedicate pump, then use purging equipment (e.g., portable submersible pump, bailer) to purge well. If using a portable submersible pump, lower pump to depth (consistent with previous smapling events) that ensures pump will not draw water level down to intake and, if possible, is positioned above the top of the well screen.

Ensure that portable purging equipment is properly decontaminated prior to use. Any decontamination must be documented (e.g., material used to decontaminate equipment, rinsing method, containment of waste, waste disposal).

Measure and/or record purge rate periodically. Collect purge sample to measure parameters periodically. Parameters should stablize (within 10% of previous three readings) before collecting the water quality sample.

Use the appropriate sample containers provided by the analytical laboratory. Sample containers shoud be labeled prior to sample collection. The sample label should include: Sample ID (often well ID), sample date and time of collection, sampling personnel, preservative used (if any), and the analytical method to be used on the sample.

All samples should be preserved as soon as possible in an ice chest containing ice. The samples should be chilled and maintained at 4 o

Redlands Regular Meeting of 01-18-2022 Page 441 of 1274 Groundwater Monitoring Protocols, Standards, and Sites
Best Management Practice

1. OBJECTIVE
The objective of this Best Management Practice (BMP) is to assist in the development of Monitoring Protocols. The California Department of Water Resources (the Department or DWR) has developed this document as part of the obligation in the Technical Assistance chapter (Chapter 7) of the Sustainable Groundwater Management Act (SGMA) to support the long-term sustainability of California’s groundwater basins.

Information provided in this BMP provides technical assistance to Groundwater Sustainability Agencies (GSAs) and other stakeholders to aid in the establishment of consistent data collection processes and procedures. In addition, this BMP can be used by GSAs to adopt a set of sampling and measuring procedures that will yield similar data regardless of the monitoring personnel. Finally, this BMP identifies available resources to support the development of monitoring protocols.

This BMP includes the following sections:

1. Objective. A brief description of how and where monitoring protocols are required under SGMA and the overall objective of this BMP.

2. Use and Limitations. A brief description of the use and limitations of this BMP.

3. Monitoring Protocol Fundamentals. A description of the general approach and background of groundwater monitoring protocols.

4. Relationship of Monitoring Protocols to other BMPs. A description of how this BMP is connected with other BMPS.

5. Technical Assistance. Technical content providing guidance for regulatory sections.

6. Key Definitions. Descriptions of definitions identified in the GSP Regulations or SGMA.

7. Related Materials. References and other materials that provide supporting information related to the development of Groundwater Monitoring Protocols.

Redlands Regular Meeting of 01-18-2022 Page 442 of 1274

2. USE AND LIMITATIONS
BMPs developed by the Department provide technical guidance to GSAs and other stakeholders. Practices described in these BMPs do not replace the GSP Regulations, nor do they create new requirements or obligations for GSAs or other stakeholders. In addition, using this BMP to develop a GSP does not equate to an approval determination by the Department. All references to GSP Regulations relate to Title 23 of the California Code of Regulations (CCR), Division 2, Chapter 1.5, and Subchapter 2. All references to SGMA relate to California Water Code sections in Division 6, Part 2.74.

3. MONITORING PROTOCOL FUNDAMENTALS
Establishing data collection protocols that are based on best available scientific methods is essential. Protocols that can be applied consistently across all basins will likely yield comparable data. Consistency of data collection methods reduces uncertainty in the comparison of data and facilitates more accurate communication within basins as well as between basins.

Basic minimum technical standards of accuracy lead to quality data that will better support implementation of GSPs.

4. RELATIONSHIP OF MONITORING PROTOCOL TO OTHER BMPS
Groundwater monitoring is a fundamental component of SGMA, as each GSP must include a sufficient network of data that demonstrates measured progress toward the achievement of the sustainability goal for each basin. For this reason, a standard set of protocols need to be developed and utilized.

It is important that data is developed in a manner consistent with the basin setting, planning, and projects/management actions steps identified on Figure 1 and the GSP Regulations. The inclusion of monitoring protocols in the GSP Regulations also emphasizes the importance of quality empirical data to support GSPs and provide comparable information from basin to basin.

Figure 1 provides a logical progression for the development of a GSP and illustrates how monitoring protocols are linked to other related BMPs. This figure also shows the context of the BMPs as they relate to various steps to sustainability as outlined in the GSP Regulations. The monitoring protocol BMP is part of the Monitoring step identified in Figure 1.

Redlands Regular Meeting of 01-18-2022 Page 444 of 1274

5. TECHNICAL ASSISTANCE
The GSP Regulations specifically call out the need to utilize protocols identified in this BMP, or develop similar protocols. The following technical protocols provide guidance based upon existing professional standards and are commonly adopted in various groundwater-related programs. They provide clear techniques that yield quality data for use in the various components of the GSP. They can be further elaborated on by individual GSAs in the form of standard operating procedures which reflect specific local requirements and conditions. While many methodologies are suggested in this BMP, it should be understood that qualified professional judgment should be used to meet the specific monitoring needs.

The following BMPs may be incorporated into a GSP’s monitoring protocols section for collecting groundwater elevation data. A GSP that adopts protocols that deviate from these BMPs must demonstrate that they will yield comparable data.

PROTOCOLS FOR ESTABLISHING A MONITORING PROGRAM
The protocol for establishment of a monitoring program should be evaluated in conjunction with the Monitoring Network and Identification of Data Gaps BMP and other BMPs. Monitoring protocols must take into consideration the Hydrogeologic Conceptual Model, Water Budget, and Modeling BMPs when considering the data needs to meet GSP objectives and the sustainability goal.

It is suggested that each GSP incorporate the Data Quality Objective (DQO) process following the U.S. EPA Guidance on Systematic Planning Using the Data Quality Objectives Process (EPA, 2006). Although strict adherence to this method is not required, it does provide a robust approach to consider and assures that data is collected with a specific purpose in mind, and efforts for monitoring are as efficient as possible to achieve the objectives of the GSP and compliance with the GSP Regulations. 23 CCR §352.2. Monitoring Protocols. Each Plan shall include monitoring protocols adopted by the Agency for data collection and management, as follows:
(a) Monitoring protocols shall be developed according to best management practices. (b) The Agency may rely on monitoring protocols included as part of the best management practices developed by the Department, or may adopt similar monitoring protocols that will yield comparable data.
(c) Monitoring protocols shall be reviewed at least every five years as part of the periodic evaluation of the Plan, and modified as necessary.

Redlands Regular Meeting of 01-18-2022 Page 445 of 1274 The DQO process presents a method that can be applied directly to the sustainability criteria quantitative requirements through the following steps.

1. State the problem – Define sustainability indicators and planning considerations of the GSP and sustainability goal.

2. Identify the goal – Describe the quantitative measurable objectives and minimum thresholds for each of the sustainability indicators.

3. Identify the inputs – Describe the data necessary to evaluate the sustainability indicators and other GSP requirements (i.e. water budget).

4. Define the boundaries of the study – This is commonly the extent of the Bulletin 118 groundwater basin or subbasin, unless multiple GSPs are prepared for a given basin. In that case, evaluation of the coordination plan and specifically how the monitoring will be comparable and meet the sustainability goals for the entire basin.

5. Develop an analytical approach – Determine how the quantitative sustainability indicators will be evaluated (i.e. are special analytical methods required that have specific data needs).

6. Specify performance or acceptance criteria – Determine what quality the data must have to achieve the objective and provide some assurance that the analysis is accurate and reliable.

7. Develop a plan for obtaining data – Once the objectives are known determine how these data should be collected. Existing data sources should be used to the greatest extent possible.

These steps of the DQO process should be used to guide GSAs to develop the most efficient monitoring process to meet the measurable objectives of the GSP and the sustainability goal. The DQO process is an iterative process and should be evaluated regularly to improve monitoring efficiencies and meet changing planning and project needs. Following the DQO process, GSAs should also include a data quality control and quality assurance plan to guide the collection of data.

Many monitoring programs already exist as part of ongoing groundwater management or other programs. To the extent possible, the use of existing monitoring data and programs should be utilized to meet the needs for characterization, historical record documentation, and continued monitoring for the SGMA program. However, an evaluation of the existing monitoring data should be performed to assure the data being collected meets the DQOs, regulatory requirements, and data collection protocol described in this BMP. While this BMP provides guidance for collection of various Redlands Regular Meeting of 01-18-2022 Page 446 of 1274 regulatory based requirements, there is flexibility among the various methodologies available to meet the DQOs based upon professional judgment (local conditions or project needs).

At a minimum, for each monitoring site, the following information or procedure should be collected and documented:
• Long-term access agreements. Access agreements should include year-round site access to allow for increased monitoring frequency.
• A unique identifier that includes a general written description of the site location, date established, access instructions and point of contact (if necessary), type of information to be collected, latitude, longitude, and elevation. Each monitoring location should also track all modifications to the site in a modification log.

PROTOCOLS FOR MEASURING GROUNDWATER LEVELS
This section presents considerations for the methodology of collection of groundwater level data such that it meets the requirements of the GSP Regulations and the DQOs of the specific GSP. Groundwater levels are a fundamental measure of the status of groundwater conditions within a basin. In many cases, relationships of the sustainability indicators may be able to be correlated with groundwater levels. The quality of this data must consider the specific aquifer being monitored and the methodology for collecting these levels.

The following considerations for groundwater level measuring protocols should ensure the following:
• Groundwater level data are taken from the correct location, well ID, and screen interval depth
• Groundwater level data are accurate and reproducible
• Groundwater level data represent conditions that inform appropriate basin management DQOs
• All salient information is recorded to correct, if necessary, and compare data • Data are handled in a way that ensures data integrity Redlands Regular Meeting of 01-18-2022 Page 447 of 1274 General Well Monitoring Information
The following presents considerations for collection of water level data that include regulatory required components as well as those which are recommended. • Groundwater elevation data will form the basis of basin-wide water-table and piezometric maps, and should approximate conditions at a discrete period in time. Therefore, all groundwater levels in a basin should be collected within as short a time as possible, preferably within a 1 to 2 week period. • Depth to groundwater must be measured relative to an established Reference Point (RP) on the well casing. The RP is usually identified with a permanent marker, paint spot, or a notch in the lip of the well casing. By convention in open casing monitoring wells, the RP reference point is located on the north side of the well casing. If no mark is apparent, the person performing the measurement should measure the depth to groundwater from the north side of the top of the well casing.
• The elevation of the RP of each well must be surveyed to the North American Vertical Datum of 1988 (NAVD88), or a local datum that can be converted to NAVD88. The elevation of the RP must be accurate to within 0.5 foot. It is preferable for the RP elevation to be accurate to 0.1 foot or less. Survey grade global navigation satellite system (GNSS) global positioning system (GPS) equipment can achieve similar vertical accuracy when corrected. Guidance for use of GPS can be found at USGS http://water.usgs.gov/osw/gps/. Hand-held GPS units likely will not produce reliable vertical elevation measurement accurate enough for the casing elevation consistent with the DQOs and regulatory requirements.
• The sampler should remove the appropriate cap, lid, or plug that covers the monitoring access point listening for pressure release. If a release is observed, the measurement should follow a period of time to allow the water level to equilibrate.
• Depth to groundwater must be measured to an accuracy of 0.1 foot below the RP.

It is preferable to measure depth to groundwater to an accuracy of 0.01 foot. Air lines and acoustic sounders may not provide the required accuracy of 0.1 foot. • The water level meter should be decontaminated after measuring each well.

Redlands Regular Meeting of 01-18-2022 Page 448 of 1274 Where existing wells do not meet the base standard as described in the GSP Regulations or the considerations provided above, new monitoring wells may need to be constructed to meet the DQOs of the GSP. The design, installation, and documentation of new monitoring wells must consider the following:
• Construction consistent with California Well Standards as described in Bulletins 74-81 and 74-90, and local permitting agency standards of practice. • Logging of borehole cuttings under the supervision of a California Professional Geologist and described consistent with the Unified Soil Classification System methods according to ASTM standard D2487-11.
• Written criteria for logging of borehole cuttings for comparison to known geologic formations, principal aquifers and aquitards/aquicludes, or specific marker beds to aid in consistent stratigraphic correlation within and across basins.
• Geophysical surveys of boreholes to aid in consistency of logging practices.

Methodologies should include resistivity, spontaneous potential, spectral gamma, or other methods as appropriate for the conditions. Selection of geophysical methods should be based upon the opinion of a professional geologist or professional engineer, and address the DQOs for the specific borehole and characterization needs.
• Prepare and submit State well completion reports according to the requirements of §13752. Well completion report documentation should include geophysical logs, detailed geologic log, and formation identification as attachments. An example well completion as-built log is illustrated in Figure 2. DWR well completion reports can be filed directly at the Online System for Well Completion Reports (OSWCR) http://water.ca.gov/oswcr/index.cfm.

Redlands Regular Meeting of 01-18-2022 Page 449 of 1274 Figure 2 – Example As-Built Multi-Completion Monitoring Well Log Redlands Regular Meeting of 01-18-2022 Page 450 of 1274 Measuring Groundwater Levels
Well construction, anticipated groundwater level, groundwater level measuring equipment, field conditions, and well operations should be considered prior collection of the groundwater level measurement. The USGS Groundwater Technical Procedures (Cunningham and Schalk, 2011) provide a thorough set of procedures which can be used to establish specific Standard Operating Procedures (SOPs) for a local agency.

Figure 3 illustrates a typical groundwater level measuring event and simultaneous pressure transducer download.

Figure 3 – Collection of Water Level Measurement and Pressure Transducer Download
The following points provide a general approach for collecting groundwater level measurements:
• Measure depth to water in the well using procedures appropriate for the measuring device. Equipment must be operated and maintained in accordance with manufacturer’s instructions. Groundwater levels should be measured to the nearest 0.01 foot relative to the RP.
• For measuring wells that are under pressure, allow a period of time for the groundwater levels to stabilize. In these cases, multiple measurements should be collected to ensure the well has reached equilibrium such that no significant changes in water level are observed. Every effort should be made to ensure that a representative stable depth to groundwater is recorded. If a well does not stabilize, the quality of the value should be appropriately qualified as a Redlands Regular Meeting of 01-18-2022 Page 451 of 1274 questionable measurement. In the event that a well is artesian, site specific procedures should be developed to collect accurate information and be protective of safety conditions associated with a pressurized well. In many cases, an extension pipe may be adequate to stabilize head in the well. Record the dimension of the extension and document measurements and configuration. • The sampler should calculate the groundwater elevation as:

𝐺𝐺𝐺𝐺𝐺𝐺 = 𝑅𝑅𝑅𝑅 − 𝐷𝐷𝐷𝐷
Where:

GWE = Groundwater Elevation
RPE = Reference Point Elevation
DTW = Depth to Water
The sampler must ensure that all measurements are in consistent units of feet, tenths of feet, and hundredths of feet. Measurements and RPEs should not be recorded in feet and inches.

Recording Groundwater Levels
• The sampler should record the well identifier, date, time (24-hour format), RPE, height of RP above or below ground surface, DTW, GWE, and comments regarding any factors that may influence the depth to water readings such as weather, nearby irrigation, flooding, potential for tidal influence, or well condition. If there is a questionable measurement or the measurement cannot be obtained, it should be noted. An example of a field sheet with the required information is shown in Figure 4. It includes questionable measurement and no measurement codes that should be noted. This field sheet is provided as an example. Standardized field forms should be used for all data collection. The aforementioned USGS Groundwater Technical Procedures offers a number of example forms.
• The sampler should replace any well caps or plugs, and lock any well buildings or covers.
• All data should be entered into the GSA data management system (DMS) as soon as possible. Care should be taken to avoid data entry mistakes and the entries should be checked by a second person for compliance with the DQOs.

Redlands Regular Meeting of 01-18-2022 Page 452 of 1274 Figure 4 – Example of Water Level Well Data Field Collection Form Redlands Regular Meeting of 01-18-2022 Page 453 of 1274 Pressure Transducers
Groundwater levels and/or calculated groundwater elevations may be recorded using pressure transducers equipped with data loggers installed in monitoring wells. When installing pressure transducers, care must be exercised to ensure that the data recorded by the transducers is confirmed with hand measurements.

The following general protocols must be followed when installing a pressure transducer in a monitoring well:
• The sampler must use an electronic sounder or chalked steel tape and follow the protocols listed above to measure the groundwater level and calculate the groundwater elevation in the monitoring well to properly program and reference the installation. It is recommended that transducers record measured groundwater level to conserve data capacity; groundwater elevations can be calculated at a later time after downloading.
• The sampler must note the well identifier, the associated transducer serial number, transducer range, transducer accuracy, and cable serial number. • Transducers must be able to record groundwater levels with an accuracy of at least 0.1 foot. Professional judgment should be exercised to ensure that the data being collected is meeting the DQO and that the instrument is capable.

Consideration of the battery life, data storage capacity, range of groundwater level fluctuations, and natural pressure drift of the transducers should be included in the evaluation.
• The sampler must note whether the pressure transducer uses a vented or nonvented cable for barometric compensation. Vented cables are preferred, but nonvented units provide accurate data if properly corrected for natural barometric pressure changes. This requires the consistent logging of barometric pressures to coincide with measurement intervals.
• Follow manufacturer specifications for installation, calibration, data logging intervals, battery life, correction procedure (if non-vented cables used), and anticipated life expectancy to assure that DQOs are being met for the GSP. • Secure the cable to the well head with a well dock or another reliable method.

Mark the cable at the elevation of the reference point with tape or an indelible marker. This will allow estimates of future cable slippage. • The transducer data should periodically be checked against hand measured groundwater levels to monitor electronic drift or cable movement. This should happen during routine site visits, at least annually or as necessary to maintain data integrity.

Redlands Regular Meeting of 01-18-2022 Page 454 of 1274 • The data should be downloaded as necessary to ensure no data is lost and entered into the basin’s DMS following the QA/QC program established for the GSP. Data collected with non-vented data logger cables should be corrected for atmospheric barometric pressure changes, as appropriate. After the sampler is confident that the transducer data have been safely downloaded and stored, the data should be deleted from the data logger to ensure that adequate data logger memory remains.

PROTOCOLS FOR SAMPLING GROUNDWATER QUALITY
The following protocols can be incorporated into a GSP’s monitoring protocols for collecting groundwater quality data. More detailed sampling procedures and protocols are included in the standards and guidance documents listed at the end of this BMP. A GSP that adopts protocols that deviate from these BMPs must demonstrate that the adopted protocols will yield comparable data.

In general, the use of existing water quality data within the basin should be done to the greatest extent possible if it achieves the DQOs for the GSP. In some cases it may be necessary to collect additional water quality data to support monitoring programs or evaluate specific projects. The USGS National Field Manual for the Collection of Water Quality Data (Wilde, 2005) should be used to guide the collection of reliable data. Figure 5 illustrates a typical groundwater quality sampling setup.

Figure 5 – Typical Groundwater Quality Sampling Event
Redlands Regular Meeting of 01-18-2022 Page 455 of 1274 All analyses should be performed by a laboratory certified under the State Environmental Laboratory Accreditation Program. The specific analytical methods are beyond the scope of this BMP, but should be commiserate with other programs evaluating water quality within the basin for comparative purposes.

Groundwater quality sampling protocols should ensure that:
• Groundwater quality data are taken from the correct location • Groundwater quality data are accurate and reproducible • Groundwater quality data represent conditions that inform appropriate basin management and are consistent with the DQOs
• All salient information is recorded to normalize, if necessary, and compare data • Data are handled in a way that ensures data integrity The following points are general guidance in addition to the techniques presented in the previously mentioned USGS National Field Manual for the Collection of Water Quality Data.

Standardized protocols include the following:
• Prior to sampling, the sampler must contact the laboratory to schedule laboratory time, obtain appropriate sample containers, and clarify any sample holding times or sample preservation requirements.
• Each well used for groundwater quality monitoring must have a unique identifier. This identifier must appear on the well housing or the well casing to avoid confusion.
• In the case of wells with dedicated pumps, samples should be collected at or near the wellhead. Samples should not be collected from storage tanks, at the end of long pipe runs, or after any water treatment.
• The sampler should clean the sampling port and/or sampling equipment and the sampling port and/or sampling equipment must be free of any contaminants. The sampler must decontaminate sampling equipment between sampling locations or wells to avoid cross-contamination between samples.
• The groundwater elevation in the well should be measured following appropriate protocols described above in the groundwater level measuring protocols. • For any well not equipped with low-flow or passive sampling equipment, an adequate volume of water should be purged from the well to ensure that the groundwater sample is representative of ambient groundwater and not stagnant water in the well casing. Purging three well casing volumes is generally Redlands Regular Meeting of 01-18-2022 Page 456 of 1274 considered adequate. Professional judgment should be used to determine the proper configuration of the sampling equipment with respect to well construction such that a representative ambient groundwater sample is collected. If pumping causes a well to be evacuated (go dry), document the condition and allow well to recover to within 90% of original level prior to sampling. Professional judgment should be exercised as to whether the sample will meet the DQOs and adjusted as necessary.
• Field parameters of pH, electrical conductivity, and temperature should be collected for each sample. Field parameters should be evaluated during the purging of the well and should stabilize prior to sampling. Measurements of pH should only be measured in the field, lab pH analysis are typically unachievable due to short hold times. Other parameters, such as oxidation-reduction potential (ORP), dissolved oxygen (DO) (in situ measurements preferable), or turbidity, may also be useful for meeting DQOs of GSP and assessing purge conditions. All field instruments should be calibrated daily and evaluated for drift throughout the day.
• Sample containers should be labeled prior to sample collection. The sample label must include: sample ID (often well ID), sample date and time, sample personnel, sample location, preservative used, and analytes and analytical method. • Samples should be collected under laminar flow conditions. This may require reducing pumping rates prior to sample collection.
• Samples should be collected according to appropriate standards such as those listed in the Standard Methods for the Examination of Water and Wastewater, USGS National Field Manual for the Collection of Water Quality Data, or other appropriate guidance. The specific sample collection procedure should reflect the type of analysis to be performed and DQOs.
• All samples requiring preservation must be preserved as soon as practically possible, ideally at the time of sample collection. Ensure that samples are appropriately filtered as recommended for the specific analyte. Entrained solids can be dissolved by preservative leading to inconsistent results of dissolve analytes. Specifically, samples to be analyzed for metals should be field-filtered prior to preservation; do not collect an unfiltered sample in a preserved container.
• Samples should be chilled and maintained at 4 °C to prevent degradation of the sample. The laboratory’s Quality Assurance Management Plan should detail appropriate chilling and shipping requirements.

Redlands Regular Meeting of 01-18-2022 Page 457 of 1274 • Samples must be shipped under chain of custody documentation to the appropriate laboratory promptly to avoid violating holding time restrictions. • Instruct the laboratory to use reporting limits that are equal to or less than the applicable DQOs or regional water quality objectives/screening levels.

Special protocols for low-flow sampling equipment
In addition to the protocols listed above, sampling using low-flow sample equipment should adopt the following protocols derived from EPA’s Low-flow (minimal drawdown) ground-water sampling procedures (Puls and Barcelona, 1996). These protocols apply to low-flow sampling equipment that generally pumps between 0.1 and 0.5 liters per minute. These protocols are not intended for bailers.

Special protocols for passive sampling equipment
In addition to the protocols listed above, passive diffusion samplers should follow protocols set forth in USGS Fact Sheet 088-00.

PROTOCOLS FOR MONITORING SEAWATER INTRUSION
Monitoring seawater intrusion requires analysis of the chloride concentrations within groundwater of each principal aquifer subject to seawater intrusion. While no significant standardized approach exists, the methodologies described above for degraded water quality can be applied for the collection of groundwater samples. In addition to the protocol described above, the following protocols should be followed:
• Water quality samples should be collected and analyzed at least semi-annually.

Samples will be analyzed for dissolved chloride at a minimum. It may be beneficial to include analyses of iodide and bromide to aid in determination of salinity source. More frequent sampling may be necessary to meet DQOs of GSP.

The development of surrogate measures of chloride concentration may facilitate cost-effective means to monitor more frequently to observe the range of conditions and variability of the flow dynamics controlling seawater intrusion. • Groundwater levels will be collected at a frequency adequate to characterize changes in head in the vicinity of the leading edge of degraded water quality in each principal aquifer. Frequency may need to be increased in areas of known preferential pathways, groundwater pumping, or efficacy evaluation of mitigation projects.
• The use of geophysical surveys, electrical resistivity, or other methods may provide for identification of preferential pathways and optimize monitoring well placement and evaluation of the seawater intrusion front. Professional judgment Redlands Regular Meeting of 01-18-2022 Page 458 of 1274 should be exercised to determine the appropriate methodology and whether the DQOs for the GSP would be met.

PROTOCOLS FOR MEASURING STREAMFLOW
Monitoring of streamflow is necessary for incorporation into water budget analysis and for use in evaluation of stream depletions associated with groundwater extractions. The use of existing monitoring locations should be incorporated to the greatest extent possible. Many of these streamflow monitoring locations currently follow the protocol described below.

Establishment of new streamflow discharge sites should consider the existing network and the objectives of the new location. Professional judgment should be used to determine the appropriate permitting that may be necessary for the installation of any monitoring locations along surface water bodies. Regular frequent access will be necessary to these sites for the development of ratings curves and maintenance of equipment.

To establish a new streamflow monitoring station special consideration must be made in the field to select an appropriate location for measuring discharge. Once a site is selected, development of a relationship of stream stage to discharge will be necessary to provide continuous estimates of streamflow. Several measurements of discharge at a variety of stream stages will be necessary to develop the ratings curve correlating stage to discharge. The use of Acoustic Doppler Current Profilers (ADCPs) can provide accurate estimates of discharge in the correct settings. Professional judgment must be exercised to determine the appropriate methodology. Following development of the ratings curve a simple stilling well and pressure transducer with data logger can be used to evaluate stage on a frequent basis. A simple stilling well and staff gage is illustrated in Figure 6.

Streamflow measurements should be collected, analyzed, and reported in accordance with the procedures outlined in USGS Water Supply Paper 2175, Volume 1. – Measurement of Stage Discharge and Volume 2. – Computation of Discharge. This methodology is currently being used by both the USGS and DWR for existing streamflow monitoring throughout the State.

PROTOCOLS FOR MEASURING SUBSIDENCE
Evaluating and monitoring inelastic land subsidence can utilize multiple data sources to evaluate the specific conditions and associated causes. To the extent possible, the use of existing data should be utilized. Subsidence can be estimated from numerous techniques, they include: level surveying tied to known stable benchmarks or benchmarks located outside the area being studied for possible subsidence; installing and tracking changes in borehole extensometers; obtaining data from continuous GPS (CGPS) locations, static GPS surveys or Real-Time-Kinematic (RTK) surveys; or analyzing Interferometric Synthetic Aperture Radar (InSAR) data. No standard procedures exist for collecting data from the potential subsidence monitoring approaches. However, an approach may include:
• Identification of land subsidence conditions.
o Evaluate existing regional long-term leveling surveys of regional infrastructure, i.e. roadways, railroads, canals, and levees. o Inspect existing county and State well records where collapse has been noted for well repairs or replacement.
o Determine if significant fine-grained layers are present such that the potential for collapse of the units could occur should there be significant depressurization of the aquifer system.

Redlands Regular Meeting of 01-18-2022 Page 460 of 1274 o Inspect geologic logs and the hydrogeologic conceptual model to aid in identification of specific units of concern.
o Collect regional remote-sensing information such as InSAR, commonly provided by USGS and NASA. Data availability is currently limited, but future resources are being developed.
• Monitor regions of suspected subsidence where potential exists. o Establish CGPS network to evaluate changes in land surface elevation. o Establish leveling surveys transects to observe changes in land surface elevation.
o Establish extensometer network to observe land subsidence. An example of a typical extensometer design is illustrated in Figure 7. There are a variety of extensometer designs and they should be selected based on the specific DQOs.

Various standards and guidance documents for collecting data include:
• Leveling surveys must follow surveying standards set out in the California Department of Transportation’s Caltrans Surveys Manual. • GPS surveys must follow surveying standards set out in the California Department of Transportation’s Caltrans Surveys Manual. • USGS has been performing subsidence surveys within several areas of California.

These studies are sound examples for appropriate methods and should be utilized to the extent possible and where available:
o http://ca.water.usgs.gov/land_subsidence/california-subsidencemeasuring.html • Instruments installed in borehole extensometers must follow the manufacturer’s instructions for installation, care, and calibration.
• Availability of InSAR data is improving and will increase as programs are developed. This method requires expertise in analysis of the raw data and will likely be made available as an interpretative report for specific regions.

4 INTRODUCTION TO CASGEM PROGRAM
In November 2009 Part 2.11 (Groundwater Monitoring) was added to Division 6 of the Water Code by Senate Bill 6 (7th Extraordinary Session) (SB 6), a copy of which is included in the Appendix. (All statutory references in this document are to the Water Code.) The new law directs that groundwater elevations in all basins and subbasins in California be regularly and systematically monitored, preferably by local entities, with the goal of demonstrating seasonal and long-term trends in groundwater elevations.

The Department of Water Resources (DWR) is directed to make the resulting information readily and widely available.

DWR developed the California Statewide Groundwater Elevation Monitoring (CASGEM) program in accordance with SB 6 to establish a permanent, locally-managed system to monitor groundwater elevation in California’s alluvial groundwater basins and subbasins identified in DWR Bulletin 118. The CASGEM program will rely and build on the many, established local long-term groundwater monitoring and management programs. DWR’s role is to coordinate information collected locally through the CASGEM program and to maintain the collected groundwater elevation data in a readily and widely available public database. DWR will also continue measuring its current network of groundwater monitoring wells as funding allows.

The goals of the CASGEM program are to:

Establish procedures for notification and data reporting by prospective Monitoring Entities (this document)
Verify local Monitoring Entities in accordance with the Water Code Develop an interface for local entities to enter data into a database compatible with DWR’s Water Data Library
Maintain the database and make it easily accessible to the public and local entities for use in water supply planning and management If no local entities volunteer to monitor groundwater elevations in a basin or part of a basin, DWR may be required to develop a monitoring program for that part. If DWR takes over monitoring of a basin, certain entities in the basin may not be eligible for water grants or loans administered by the state.

During August and September 2010, DWR held 10 workshops throughout the state in cooperation with Association of California Water Agencies (ACWA) to introduce the CASGEM program and explain the purpose and process of the program to local agencies and stakeholders. A copy of the DWR presentation is available on the CASGEM website (http://www.water.ca.gov/groundwater/casgem). A summary of Redlands Regular Meeting of 01-18-2022 Page 470 of 1274 CASGEM Procedures for Monitoring Entity Reporting
5 Frequently Asked Questions (FAQs), primarily from the workshops, is provided in on the CASGEM website.

DWR’s main role is to administer the CASGEM program through providing public outreach; creating and maintaining the CASGEM website and online data submittal system; and, supporting local entities through the process of becoming a Monitoring Entity and preparing Monitoring Plans. DWR will use the CASGEM website to provide up-to-date information on the program. The website will also be the access point for the online notification and data submittal systems.

Staff from the DWR regional offices will be available to assist potential Monitoring Entities with the online notification submittal process. After receiving notification from prospective Monitoring Entities, DWR will review them for completeness, verify the authority of the applying entity under Section 10927, and check for overlapping monitoring areas. DWR will advise each party on the status of their notification within three months of submittal and will work with entities to address any deficiencies in their submittals.

DWR encourages local agencies and groups to collaborate to determine who will serve as the Monitoring Entity for the area. However, if more than one party seeks to become the Monitoring Entity for the same area and overlapping monitoring area issues cannot be resolved locally, DWR will make a final determination of the Monitoring Entity for the area. DWR’s determinations will consider the order in which entities are identified in Section 10927 and other factors as described in the Water Code.

DWR will post the selection of each Monitoring Entity and its monitoring area on the CASGEM website and will notify each Monitoring Entity in writing. A map-based interface will be available for users to identify the Monitoring Entity for each basin in the state.

DWR will prepare the first status report on the CASGEM program for the Governor and Legislature by January 1, 2012. In this initial report, DWR will report on the extent of groundwater elevation monitoring within each basin. This report will include a statewide prioritization of basins based on water supply, water demand, and other factors identified in Section 10933. DWR will explore options for basins without identified monitoring, with a focus on identifying options for local monitoring. Future status reports on the CASGEM program will be prepared by DWR in years ending in 5 or 0.

6 PURPOSE OF MONITORING ENTITY REPORTING PROCEDURES
The purpose of these procedures is to introduce the CASGEM program and its components as the framework for implementing SB 6, with particular emphasis on the initial step of establishing Monitoring Entities for each Bulletin 118 basin in the state.

A summary of the requirements of local entities to comply with the CASGEM program is presented in Table 1.

Table 1. Quick Guide for Local Entities
Determine whether you qualify as a potential Monitoring Entity (see “Requirements to become Monitoring Entity” on pages 9-13) Identify the basins within your area (see Bulletin 118) Collaborate with other local entities to identify and choose the prospective Monitoring Entity (or Entities) for your area Submit Monitoring Entity notification to DWR through CASGEM website (http://www.water.ca.gov/groundwater/casgem) on or before January 1, 2011
DWR will review the notification and advise the prospective Monitoring Entity of the status of the notification within 3 months of submittal Work with staff of the DWR regional office to address any deficiencies in the submittal
If more than one party seeks to become the Monitoring Entity for the same area, work with staff of the DWR regional office to resolve Check the CASGEM website for a listing of the selected Monitoring Entities
Develop and submit a Monitoring Plan to DWR through the CASGEM website
Staff from the DWR regional office are available to assist with the Monitoring Plan and to recommend changes
Submit monitoring data to DWR through the CASGEM website on or before January 1, 2012
Redlands Regular Meeting of 01-18-2022 Page 472 of 1274 CASGEM Procedures for Monitoring Entity Reporting
7 CASGEM SCHEDULE
A timetable for implementing the CASGEM schedule is shown above.

Redlands Regular Meeting of 01-18-2022 Page 473 of 1274 CASGEM Procedures for Monitoring Entity Reporting
8 MONITORING ENTITIES
The CASGEM program establishes the framework for collaboration between local monitoring parties and DWR to collect groundwater elevation data throughout the state’s 515 basins as defined in Bulletin 118. A Monitoring Entity is a local agency or group that voluntarily takes responsibility for conducting or coordinating groundwater elevation monitoring and reporting for all or part of a groundwater basin.

To determine if you are within a Bulletin 118 basin, please refer to maps and descriptions in Bulletin 118, available online at:
http://www.water.ca.gov/groundwater/bulletin118/gwbasin_maps_descriptions.cfm.

Geographic Information System (GIS) shapefiles of the basins are also available at this website. DWR can assist in identifying other potential local monitoring parties in each basin.

ROLES AND RESPONSIBILITIES OF MONITORING ENTITIES
Through the CASGEM program, local entities with appropriate authority may notify DWR of their intent to be a Monitoring Entity. Monitoring Entities will have specific responsibilities, including:

Coordinate with DWR to establish a Monitoring Plan
Conduct or coordinate the regular and systematic monitoring of groundwater elevations as specified in the Monitoring Plan
Submit monitoring data to DWR in a timely manner
A Monitoring Entity can perform monitoring for any number of basins or portions thereof, but no area can have more than one Monitoring Entity. While the Monitoring Entity is responsible for compiling the data and submitting it to DWR for a particular area, the actual measurements can be taken by any number of agencies that would work under the direction of the Monitoring Entity. (Cooperating agencies would submit data to the Monitoring Entity, not to DWR.) Thus, assuming there are no overlapping areas or gaps in basin coverage for a given area, there are three possible basic scenarios, illustrated in Figure 1:

A single Monitoring Entity that collects and reports groundwater elevation data for the entire basin (Scenario A);
Multiple Monitoring Entities that collect and report groundwater elevation data for their portion of the basin (Scenario B); or
Redlands Regular Meeting of 01-18-2022 Page 474 of 1274 CASGEM Procedures for Monitoring Entity Reporting
9 An umbrella Monitoring Entity that coordinates and reports groundwater elevation data collected by multiple agencies within the basin (Scenario C).

Figure 1. Illustration of possible Monitoring Entity scenarios for a monitored basin.

DWR currently monitors water elevations in about 4,000 wells statewide and cooperates with local and federal agencies to monitor roughly an additional 6,000 wells. DWR plans to continue monitoring groundwater elevations, contingent upon available funding. In some basins DWR currently does most, if not all, of the water-elevation monitoring. In these basins, a local entity still needs to notify DWR of their intent to become the Monitoring Entity. The Monitoring Entity must determine which DWR wells will be included in their CASGEM monitoring network. As long as DWR continues its monitoring program, the department will transmit its groundwater elevation data to the CASGEM system. However, if DWR is unable to continue monitoring for any reason, the Monitoring Entity will be required to re-evaluate its monitoring network to determine which wells to retain in its monitoring network.

Certain basic information is required for notification, including contact information and additional details depending on the authority of the entity desiring to monitor groundwater (Section 10928), as listed above. This notification information will be submitted to DWR using an online system that will be available by mid-December 2010.

MONITORING PLANS
Monitoring Entities will each develop a Monitoring Plan that includes the following sections: Monitoring Sites and Timing, Field Methods, and Data Reporting. Monitoring Plans should be completed and submitted to DWR by summer 2011. Staff from the DWR regional offices will be available to assist Monitoring Entities with the development of Monitoring Plans, if needed. In determining what information should be reported to DWR, the department will defer to existing monitoring programs if those programs result in information that demonstrates seasonal (annual high and low groundwater elevations) and long-term trends in groundwater elevations. Staff from the DWR regional offices will assist Monitoring Entities to address any gaps in basin coverage Redlands Regular Meeting of 01-18-2022 Page 480 of 1274 CASGEM Procedures for Monitoring Entity Reporting

Monitoring Plan is established with DWR, Monitoring
Entities should notify DWR of any changes to the
plan.

DATA GAPS
A data gap refers to a basin or portion of a basin that is not included in any of the Monitoring Plans
submitted to DWR. This is essentially an area that
lacks the density of monitoring wells that would allow
seasonal and long-term trends in groundwater
elevations to be determined for the basin, subbasin,
or a portion thereof. Among the 515 basins defined
by Bulletin 118, data gaps may exist for a variety of
reasons, including a lack of suitable monitoring
wells, lack of groundwater use, access issues, and
jurisdictional issues, among others.

If no local entity is able and/or willing to fill a data gap, the department may be required to perform groundwater monitoring functions. If DWR performs this monitoring, local agencies and the county that have the authority under Section 10927 to monitor the area of the data gap would be potentially ineligible for a water grant or loan awarded or administered by the state. The Monitoring Entity or entities with the authority to monitor the area of the data gap should provide detailed information regarding the nature of and reason for the data gap so that DWR may include such information in the prioritization of groundwater basins and subbasins as appropriate.

Agencies and counties that are eligible to be designated Monitoring Entities but choose not participate in the CASGEM program will not lose their state water grant and loan eligibility if their entire service area qualifies as a disadvantaged community (Water Code Section 10933.7(b)). It will be the responsibility of the local agency or county applying for a state water grant or loan to demonstrate their disadvantaged community status at the time they are applying for the grant or loan.

16 MONITORING SITES AND TIMING
The Monitoring Plan will identify the wells to be monitored and the frequency with which they will be monitored. The Monitoring Plan should explain how proposed monitoring will be sufficient to demonstrate the seasonal and long-term groundwater elevation trends in the monitored area. The density of monitoring locations will depend on the complexity of the basin.

Because of security concerns, the California Department of Public Health (DPH) routinely limits the disclosure of detailed public water supply well location information. Pursuant to Water Code Section 10931, the DWR is required to collaborate with DPH to ensure that the information reported to the CASGEM program will not result in the inappropriate disclosure of information of concern to DPH. At this time, DWR has reached no agreement with DPH regarding the appropriate treatment of public water supply well data. As a result, CASGEM does not currently plan to use such well information in its database.

The Monitoring Plan should contain a table identifying the wells to be monitored and the timing of that monitoring. Because the law specifies that information should demonstrate seasonal and long-term trends in groundwater elevations, at a minimum monitoring should be conducted at each location for the yearly high and low for the basin. The yearly high and low groundwater elevations typically occur in spring and fall, but this may vary from basin to basin. It is very important that the timing of all the measurements in the basin is coordinated. Rationale for selection of the timing (seasonal highs and lows) should be included in the Monitoring Plan.

The information on the monitoring sites and timing to be submitted in the online system should include:

Well identification number
State well number
Location (decimal latitude and longitude, North American Datum (NAD) 83) Reference point elevation (feet, North American Vertical Datum (NAVD) 88) Land surface datum (feet, NAVD88)
Map and shapefile with monitoring locations, Bulletin 118 groundwater basin boundary, and boundary of monitoring area
Frequency and timing of measurements
Redlands Regular Meeting of 01-18-2022 Page 482 of 1274 CASGEM Procedures for Monitoring Entity Reporting
17 FIELD METHODS
The consistent and documented collection of groundwater elevation data is important for ensuring that the data can be used across the state, regardless of the Monitoring Entity. The field methods should meet a common set of basic requirements; however, the methods do not have to be exactly the same. Many entities already have in place monitoring efforts that are successful in meeting local needs and that can meet the needs for this program, either as-is or with the incorporation of individual components.

The CASGEM program wishes to maintain, to the greatest extent possible, the procedures of high-quality local groundwater elevation monitoring programs, so long as they meet the overall program goals and policies. Of particular concern are the following basic requirements:

Method(s) to establish the Reference Point, including step-by-step instructions Method(s) to ensure static groundwater elevation
Method(s) to measure depth to water, including step-by-step instructions Method(s) and form(s) for recording measurements
It is the responsibility of each Monitoring Entity to develop and implement monitoring protocols that are appropriate to local groundwater basin conditions, protect the water quality of its monitoring wells, and maintain the quality of the data that it submits to the CASGEM Program. DWR has developed field guidelines (Department of Water Resources Groundwater Elevation Monitoring Guidelines) based on a review of existing field methods from DWR and other organizations, which is available on the CASGEM website. Monitoring Entities are welcome to refer to these guidelines when developing field methods for their own Monitoring Plans. However, the DWR guidelines are for internal use in the event that the Department is required to perform groundwater monitoring functions pursuant to Section 10933.5 and are not binding on any other agency. The core of the CASGEM program will rely and build on the many, established local long-term groundwater monitoring and management programs. The department will defer to existing monitoring programs that result in information that demonstrates seasonal and long-term trends in groundwater elevations.

DATA REPORTING
DWR will develop an online data submittal system for Monitoring Entities to submit their groundwater elevation data. Several methods of submitting data will be available, such as direct online data entry, or upload of data files for batch entry. Initial groundwater elevation data should be submitted to DWR by January 1, 2012. Thereafter, data Redlands Regular Meeting of 01-18-2022 Page 483 of 1274 CASGEM Procedures for Monitoring Entity Reporting
18 should be submitted as soon as possible after collection, but no later than January 1st and July 1st of each year, at the minimum. Historical data can also be submitted via the DWR data system to aid in data interpretation. All submitted data will be available to the public, except for confidential data.

Each groundwater elevation data measurement submitted to the online system should include:

Well identification number
Measurement date
Reference point and land surface elevation
Depth to water
Method of measuring water depth
Measurement quality codes
The Monitoring Entity information, well information, and groundwater elevation information is to be provided by the Monitoring Entity. Items labeled as required must be submitted to DWR to report groundwater elevations. Items labeled as recommended should be submitted to DWR if they are available, as they assist in fully evaluating the quality of measurements. DWR will provide standard form(s) for Monitoring Entities to submit groundwater elevation data online. However, if Monitoring Entities cannot use the standard form(s) or provide the data elements listed below, DWR will work cooperatively with Monitoring Entities to develop alternate methods of submitting data.

Entity Information
All entities assuming groundwater monitoring functions as delineated in Section 10927 (a)-(f) are required to submit the following information:

Monitoring Entity's name, address, telephone number, contact person name and email address, and any other relevant contact information (Section 10928 (a) (1), 10928 (b) (1))
Name, address, telephone number, email address and any other relevant contact information for entities collecting data that is submitted by a designated submitting entity (Monitoring Entity)
Groundwater basins being monitored
o Identify entire basins monitored
o Identify partial basins monitored
Well Information
The following information about each well is required for the CASGEM online system:

Redlands Regular Meeting of 01-18-2022 Page 484 of 1274 CASGEM Procedures for Monitoring Entity Reporting
19 Unique well identification number. Agencies may use an existing State Well Number, an existing local well designation, or develop their own identification name, using the following protocol:
o Agency name, abbreviation, or acronym followed by a sequential number (e.g., SGA 01)
o Groundwater basin – followed by a sequential number (e.g., Llagas 03) o Geographic name – followed by a sequential number (e.g., Yolo 12) o Well names should be 15 characters long or less
o Avoid using owner/business names or specific locational information for privacy and security
Decimal latitude/longitude coordinates of well, using horizontal datum NAD83, and the method of determining coordinates (Actual coordinates are preferred; however, Monitoring Entities may submit approximate locations, as needed, to protect the privacy of well owners. For example, to protect the privacy of a well owner, a Monitoring Entity may submit well coordinate locations that are only within 1000-feet of the actual well location.)
Groundwater basin or sub-basin
Reference point elevation of the well (feet) using NAVD88 vertical datum Elevation of land surface datum at the well (feet) using NAVD88 vertical datum Use of well (e.g., dedicated monitoring, irrigation, domestic, etc) Well completion type (e.g. single well, nested, or multi-completion wells) Depth of screened interval(s) and total well depth of well, if available (feet) Well Completion Report number (DWR Form 188), if available The following information about each well is recommended for the CASGEM online system:

State Well Number – assigned by DWR in most cases
Method by which land surface elevation was determined (for example, topographic map, GPS, etc.)
Written description of location of well, including distance from nearby landmarks and location of reference point in relation to well appurtenances (DWR Form 429) Well information comments
Groundwater Elevation Information
The following information for each groundwater elevation measurement is required for the CASGEM online system:

Well identification number (see Well Information, above) Measurement date
Reference point elevation of the well (feet) using NAVD88 vertical datum Elevation of land surface datum at the well (feet) using NAVD88 vertical datum Depth to water below reference point (feet) (unless no measurement was taken) Method of measuring water depth
Measurement Quality Codes
Redlands Regular Meeting of 01-18-2022 Page 485 of 1274 CASGEM Procedures for Monitoring Entity Reporting
20 o If no measurement is taken, a specified “no measurement” code, must be recorded. Standard codes will be provided by the online system. If a measurement is taken, a “no measurement” code is not recorded.) o If the quality of a measurement is uncertain, a “questionable measurement” code can be recorded. Standard codes will be provided by the online system. If no measurement is taken, a “questionable measurement” code is not recorded.)
Measuring agency identification
The following information for each groundwater elevation measurement is recommended for the CASGEM online system:

Measurement time (PST/PDT with military time/24 hour format) Comments about measurement, if applicable
Groundwater elevation data shall be submitted electronically to DWR’s online system.

DWR will develop electronic data transmittal (EDT) alternatives and data standards to permit bulk data transfer and assist Monitoring Entities in EDT reporting to DWR. As stated above, if Monitoring Entities cannot use the standard form(s) or provide the necessary groundwater elevation data elements, DWR will work cooperatively with Monitoring Entities to develop alternate methods of submitting data.

The CASGEM online data submittal system will be compatible with the Water Data Library (WDL) (http://www.water.ca.gov/waterdatalibrary/), DWR’s existing groundwater elevation database. The CASGEM system will include data reporting options similar to those in WDL, such as hydrographs, seasonal contour data, and data downloads. The combined accessibility of the WDL and the CASGEM system will be a significant resource for local agencies in making sound groundwater management decisions.

GROUNDWATER MONITORING
Redlands Regular Meeting of 01-18-2022 Page 488 of 1274 CASGEM Procedures for Monitoring Entity Reporting
23 Senate Bill No. 6
CHAPTER 1
An act to add Part 2.11 (commencing with Section 10920) to Division 6 of, and to repeal and add Section 12924 of, the Water Code, relating to groundwater. [Approved by Governor November 6, 2009. Filed with
Secretary of State November 6, 2009.]
Legislative Counsel’s Digest
SB 6, Steinberg. Groundwater.
(1) Existing law authorizes a local agency whose service area includes a groundwater basin that is not subject to groundwater management to adopt and implement a groundwater management plan pursuant to certain provisions of law. Existing law requires a groundwater management plan to include certain components to qualify as a plan for the purposes of those provisions, including a provision that establishes funding requirements for the construction of certain groundwater projects.

This bill would establish a groundwater monitoring program pursuant to which specified entities, in accordance with prescribed procedures, may propose to be designated by the Department of Water Resources as groundwater monitoring entities, as defined, for the purposes of monitoring and reporting with regard to groundwater elevations in all or part of a basin or subbasin, as defined. The bill would require the department to work cooperatively with each monitoring entity to determine the manner in which groundwater elevation information should be reported to the department. The bill would authorize the department to make recommendations for improving an existing monitoring program, and to require additional monitoring wells under certain circumstances. Under certain circumstances, the department would be required to perform groundwater monitoring functions. In that event, prescribed entities with authority to assume groundwater monitoring functions with regard to a basin or subbasin for which the department has assumed those functions would not be eligible for a water grant or loan awarded or administered by the state.
(2) Existing law requires the department to conduct an investigation of the state’s groundwater basins and to report its findings to the Governor and the Legislature not later than January 1, 1980.

Redlands Regular Meeting of 01-18-2022 Page 489 of 1274 CASGEM Procedures for Monitoring Entity Reporting
24 This bill would repeal that provision. The department would be required to conduct an investigation of the state’s groundwater basins and to report its findings to the Governor and the Legislature not later than January 1, 2012, and thereafter in years ending in 5 or

0. (3) The bill would take effect only if SB 1 and SB 7 of the 2009–10 7th Extraordinary Session of the Legislature are enacted and become effective.

4 Projects and Management Actions

4.1 Introduction to Projects and Management Actions
Sub article 5 of Article 5 of the California Code of Regulations (CCR) Division 2 Chapter 1.5 (23 CCR, Section 354.42–354.44) describes the criteria for projects and management actions to be included in a Groundwater Sustainability Plan (GSP) that will help achieve the sustainability goal established for the Plan Area over the planning and implementation horizon. Currently, the Yucaipa Subbasin is being managed sustainably. The importation of State Water Project (SWP) water as a supplemental source of water has allowed the water purveyors to reduce groundwater production in the Subbasin to below the estimated sustainable yield. Consequently, groundwater levels have recovered 50 to 200 feet in the past 10 years with groundwater storage increasing by approximately 18,000 AF (Section 2.8).

Future projections with groundwater production constrained to the estimated sustainable yield of 10,980 AFY, which is higher than the average annual extraction of 9,100 AFY observed from the 2014 WY to the-2018 WY period, indicate that the Yucaipa Subbasin will not experience undesirable results over the 50-year planning and implementation period. The simulated Future Baseline with Climate Change II scenario using the YIHM indicated that conditions in the Calimesa Management Area may decline below the measurable objective and trend toward the minimum threshold (Figure 3-35). Under such conditions that may be experienced in the Calimesa management area and throughout the Subbasin, the Yucaipa GSA has defined management actions that will be implemented to prevent undesirable results.

The management actions included in this Chapter document the actions that the Yucaipa GSA will implement in the event that groundwater elevations in one or more management areas decline below their respective measurable objectives and minimum thresholds. The management actions are not currently necessary to achieve sustainability in the Plan Area, which has experienced rising groundwater levels and increased groundwater in storage since 2008 (Section 2.7). However, the following management actions will be implemented, as necessary, to respond to declining conditions that deviate from the future predictions by the YIHM.

Currently, no projects have been identified as necessary to achieve groundwater sustainability in the Plan Area.

Member agencies of the Yucaipa GSA have constructed spreading basins and stormwater capture basins, and are in the process of designing and constructing new ones, to enhance recharge to the Subbasin. The Wilson Creek and Oak Glen Creek spreading basins were designed to receive SWP water from the East Branch Extension and to capture major stormwater flows.

4.2 Management Actions
Minimum thresholds and measurable objectives were defined for the four management areas in the Plan Area. For the North Bench, Calimesa and Western Heights management areas, minimum thresholds were defined at either the historical low in groundwater elevations in the North Bench Management Area, or below historical lows in the Calimesa and Western Heights management areas. The minimum threshold and measurable objective for the San Timoteo management area were defined to prevent significant and unreasonable effects on groundwaterdependent ecosystems (GDEs) identified along San Timoteo Creek. A drought buffer was defined for the North Bench, Calimesa and Western Heights management areas to provide operational flexibility between their respective measurable objectives and minimum thresholds.

4.2.1 Management Action No. 1 – Reduce Net Use of Groundwater When Groundwater Levels Decline below Measurable Objectives The drought buffers established for the North Bench, Calimesa and Western Heights management areas provide operational flexibility to implement management actions when groundwater conditions decline below their respective measurable objectives (Section 3.4). The following management actions for these three management areas will prevent undesirable results related to the chronic lowering of groundwater levels, reduction in groundwater storage, and land subsidence. The management action implemented when groundwater levels decline below the measurable objective for the San Timoteo management area will prevent significant and unreasonable effects resulting in a loss in surface water interconnected with shallow groundwater that sustain GDEs.

4.2.1.1 North Bench Management Area
The North Bench management area includes eight RMPs each associated with a groundwater elevation representing the measurable objective at 230,000 AF in storage and the minimum threshold at 220,000 AF in storage (Table 3-3). Currently, groundwater levels are 50 feet to 130 feet above the measurable objective levels designated at the RMPs (Table 4-1).

4-3 October 2021
The YIHM predicts that future groundwater elevations with groundwater production constrained to the estimated sustainable yield of 3,940 AFY will remain above the measurable objective levels associated with each RMP (Figures 3-7 to 3-14). However, the following conditions will trigger management actions to be implemented by the Yucaipa GSA:
1) If groundwater elevations decline below the measurable objective levels at 50% or more of the RMPs (Table 4-1) for 2 consecutive years, then the following management action will be implemented:
a) The net use of groundwater from the North Bench management area will decrease by 25% of the estimated sustainable yield of 3,940 AFY, or by 990 AFY. The Yucaipa GSA will implement this management action by either reducing groundwater production by 990 AFY, artificially recharging the aquifer with an additional 990 AFY of supplemental water, enacting water conservation programs or other programs that result in a net reduction of groundwater use by 990 AFY, or any combination of these actions that result in a net reduction of groundwater use by 990 AFY. Because the management area is not experiencing or is expected to experience conditions below the measurable objective through the 50-year planning and implementation horizon, no interim milestones are defined in this GSP. However, if conditions do develop and this management action is implemented, then the Yucaipa GSA will identify interim milestones at that time to evaluate progress in achieving groundwater sustainability. b) The 25% net reduction in groundwater use, which may be achieved with a reduction in groundwater production from 3,940 AFY to 2,950 AFY, was selected because historical data indicated that, when groundwater production was at 3,000 AFY or less, groundwater levels and the volume in storage were stable or increased during periods of “below normal” to “wet” water year types (Figures 2-3, 3-3, and 3- 6). The Yucaipa GSA, at its discretion, may modify the 25% reduction (e.g., implement a higher percentage of reduction) if this rate is not sufficient to improve conditions in the management area and avoid undesirable results.
c) Implementing this management action will also require the Yucaipa GSA to reevaluate and, possibly, recalibrate the YIHM to improve the accuracy of the model in predicting future conditions. This action will be implemented if the occurrence is outside the scheduled 5-year evaluation, which already includes a reevaluation of the YIHM.
2) If conditions continue to decline and groundwater elevations at 50% or more of the RMPs fall below their respective minimum threshold levels (Table 4-1) for 2 consecutive years, then the following management action will be implemented:
a) The net use of groundwater from the North Bench management area will decrease by 35% of the estimated sustainable yield of 3,940 AFY, or by 1,380 AFY. The Yucaipa GSA will achieve this management action by either reducing groundwater production by 1,380 AFY, artificially recharge the aquifer with an additional 1,390 AFY of supplemental water, enact water conservation programs or other programs that result in a net reduction of groundwater withdrawal by 1,380 AFY, or any combination of these actions that result in a net reduction of groundwater withdrawal by 1,380 AFY. Because the management area is not experiencing or is expected to experience conditions below the minimum threshold through the 50-year planning and implementation horizon, no interim milestones are defined in this GSP. However, if conditions do fall below the minimum threshold and this management action is implemented, then the Yucaipa GSA will identify interim milestones at that time to evaluate progress in improving conditions to achieve groundwater sustainability. b) The 35% net reduction in groundwater use, which may represent a reduction in groundwater production to 2,560 AFY, was selected because historical data indicated that, when groundwater production was at 2,600 AFY or less, groundwater levels and the volume in storage were stable or increased during periods Redlands Regular Meeting of 01-18-2022 Page 595 of 1274 ADMINISTRATIVE DRAFT – GROUNDWATER SUSTAINABILITY PLAN FOR THE YUCAIPA SUBBASIN CHAPTER 4 – PROJECTS AND MANAGEMENT ACTIONS

of “dry” to “wet” water year types (Figures 2-3, 3-3, and 3-6). The Yucaipa GSA, at its discretion, may modify the 35% reduction (e.g., implement a higher percentage of reduction) if this rate is not sufficient to improve conditions in the management area.

4.2.1.1.1 Measurable Objective Expected to Benefit
The measurable objective established for the sustainability indicators of chronic lowering of groundwater levels, reduction in groundwater storage, and land subsidence would benefit from the implementation of this management action. The goal of the management action is to reduce the net use of groundwater from the management area by 25% to 35% of the estimated sustainable yield until conditions improve to the measurable objective where the management area is managed sustainably.

4.2.1.1.2 Expected Benefits and Evaluation
The sustainability criteria established for the North Bench management area were designed to protect the long-term groundwater supply and maintain production for the existing wells operated by YVWD and private users. The establishment of a drought buffer, represented by a range in the volume in storage from 220,000 to 230,000 AF, provides operational flexibility for the Yucaipa GSA to implement these management actions to avoid or improve conditions from undesirable results. These actions allow the management area to recover during “dry“ to “wet” water year types when recharge, either naturally or artificially, or both, will exceed the net withdrawal of groundwater.

Groundwater in storage will increase and chronic declines in groundwater elevation will cease or reverse with a net reduction in groundwater withdrawal from the management area. Groundwater in storage will be measured using groundwater elevations as a proxy. If groundwater elevations stabilize, or rise at the groundwater level RMPs, the management action will have succeeded in increasing the volume of groundwater in storage and prevented the chronic decline in groundwater levels. Conditions at the measurable objective or higher are at or above the historical low, which will negate the undesirable result of land subsidence potentially occurring due to a long-term groundwater level decline below the historical low.

4.2.1.1.3 Circumstances for Implementation
This management action would be implemented under the following circumstances:

1. When groundwater levels measured at 50% or more of the RMPs fall below their respective measurable objective levels for 2 consecutive years, or

2. When groundwater levels measured at 50% or more of the RMPs fall below their respective minimum threshold levels for 2 consecutive years.

4.2.1.1.4 Public Noticing
Public noticing is not required for this management action, which would be undertaken under the Yucaipa GSA’s authority to control groundwater withdrawals from the Plan Area, including the North Bench management area. The Yucaipa GSA will notify private well owners that will be affected by the implementation of this management action if it requires a reduction in their respective groundwater production.

4-5 October 2021

4.2.1.1.5 Permitting and Regulatory Process
No additional permitting or regulatory oversight is necessary to implement this management action, which would be undertaken under the Yucaipa GSA’s authority per Water Code, Section 10726.4.

4.2.1.1.6 Implementation Schedule
There is no specific implementation schedule for this management action as projected groundwater levels indicate this management action will not be required. The Yucaipa GSA will implement this management action within six months of determining that one of the criteria for implementation described in Section 4.2.1.1.3 has been met.

4.2.1.1.7 Legal Authority
The Yucaipa GSA has the legal authority to operate and regulate the production from water supply wells in the Plan Area per Water Code, Section 10726.4; and to import surface water (e.g., SWP water) or other supplemental water to artificially recharge the Subbasin per Water Code, Section 10726.2. No additional legal authority is required.

4.2.1.1.8 Estimated Costs
The costs associated with the implementation of this management action have not yet been estimated. However, if this management action is implemented and groundwater production is decreased, then additional costs may be incurred by YVWD (the only water purveyor operating in the North Bench management area), or its respective customers, to supply additional supplemental water, enact water conservation programs, or other actions to meet water demands.

4.2.1.2 Calimesa Management Area
The Calimesa management area includes 13 RMPs; each is associated with groundwater elevations representing the measurable objective at 798,700 AF and the minimum threshold at 772,700 AF in storage (Table 3-4; Table 4-2). The measurable objective is represented by the historical low condition and indicates that no undesirable results are occurring in the management area.

The YIHM predicts that future groundwater elevations with groundwater production constrained to the estimated sustainable yield of 4,955 AFY will remain above the minimum threshold levels associated with each RMP, but will fall below the measurable objective levels under the Future Baseline with Climate Change II scenario (Figures 3-22 to 3-34). The following conditions will trigger management actions to be implemented by the Yucaipa GSA:
1) If groundwater elevations decline at 50% or more of the RMPs below their respective measurable objective levels for two consecutive years, then the following management action will be implemented:
a) The net use of groundwater from the Calimesa management area will be reduced under a three-tier structure depending on the volume of groundwater in storage below the historical low of 798,700 AF.

Actions to be implemented under the three-tier structure are as follows:
i) The first tier extends from 798,700 to 790,700 AF, or the top 8,000 AF in the drought buffer (Figure 4- 1). Groundwater elevations at the RMPs that represent the historical low (i.e., the top of tier 1) range from 2,024 to 2,204 feet NAVD88 (Table 4-2). If groundwater elevations decline at 50% or more of the RMPs below their respective tier 1 levels for two consecutive years, then a net reduction in groundwater use by 5% of the estimated sustainable yield of 4,955 AFY, or by 250 AFY, is required. The Yucaipa GSA will implement this management action by either reducing groundwater production by 250 AFY, Redlands Regular Meeting of 01-18-2022 Page 598 of 1274 ADMINISTRATIVE DRAFT – GROUNDWATER SUSTAINABILITY PLAN FOR THE YUCAIPA SUBBASIN CHAPTER 4 – PROJECTS AND MANAGEMENT ACTIONS

4-7 October 2021
artificially recharging the aquifer with an additional 250 AFY of supplemental water, enacting water conservation programs or other programs that result in a net reduction of groundwater use by 250 AFY, or any combination of these actions that result in a net reduction of groundwater use by 250 AFY.

Currently, no interim milestones are defined because the management area is managed sustainably and conditions are at or above the measurable objective. However, if conditions decline to this second tier in the drought buffer, then this management action would be implemented and the Yucaipa GSA will identify interim milestones at that time to evaluate progress in achieving groundwater sustainability. iii) The third tier extends from 781,700 to 772,700 AF, or the bottom 9,000 AF in the drought buffer (Figure 4-1). Groundwater elevations at the RMPs that represent the top of tier 3 range from 1,972 to 2,191 feet NAVD88 (Table 4-2). If groundwater elevations decline at 50% or more of the RMPs below their respective tier 3 levels for two consecutive years, then a net reduction in groundwater use by 15% of the estimated sustainable yield of 4,955 AFY, or by 750 AFY, is required. The Yucaipa GSA will implement this management action by either reducing groundwater production by 750 AFY, artificially recharge the aquifer with an additional 750 AFY of supplemental water, enact water conservation programs or other programs that result in a net reduction of groundwater use by 750 AFY, or any combination of these actions that result in a net reduction of groundwater use by 750 AFY. Currently, no interim milestones are defined because the management area is managed sustainably and conditions are at or above the measurable objective. However, if conditions decline to this third tier in the drought buffer, then this management action would be implemented and the Yucaipa GSA will identify interim milestones at that time to evaluate progress in achieving groundwater sustainability. b) The 5% to 15% net reduction in groundwater use was selected because historical data indicated that, when groundwater production was at these rates or less, groundwater levels and the volume in storage were stable or increased during periods of “dry” to “wet” water year types (Figures 2-3, 3-19 and 3-21). The Yucaipa GSA, at its discretion, may modify the 5% to 15% reduction (e.g., implement a higher percentage of reduction) if these rates are not sufficient to improve conditions in the management area and avoid undesirable results.
c) Implementing this management action will also require the Yucaipa GSA to reevaluate and, possibly, recalibrate the YIHM to improve the accuracy of the model in predicting future conditions. This action will be implemented if the occurrence is outside the scheduled 5-year evaluation, which already includes a reevaluation of the YIHM.

2) If conditions continue to decline and groundwater elevations at 50% or more of the RMPs fall below their respective minimum threshold levels for two consecutive years, then the following management action will be implemented:
a) Groundwater elevations at the RMPs that represent the minimum threshold range from 1,959 to 2,177 feet NAVD88 (Table 4-2). The net use of groundwater from the Calimesa management area will be reduced by 20% of the estimated sustainable yield of 4,955 AFY, or by 990 AFY. The Yucaipa GSA will achieve this management action by either reducing groundwater production by 990 AFY, artificially recharging the aquifer with an additional 990 AFY of supplemental water, enacting water conservation programs or other programs that result in a net reduction of groundwater use by 990 AFY, or any combination of these actions that result in a net reduction of groundwater use by 990 AFY. Because the management area is not experiencing or is expected to experience conditions below the minimum threshold through the 50-year planning and implementation horizon, no interim milestones are defined in this GSP. However, if conditions do fall below the minimum threshold and this management action is implemented, then the Yucaipa GSA will identify interim milestones at that time to evaluate progress in improving conditions to achieve groundwater sustainability.
b) The 20% net reduction in groundwater use, which may be achieved with a reduction in groundwater production by 990 AFY to 3,955 AFY, was selected because historical data indicated that, when groundwater production was at 4,000 AFY or less, groundwater levels and the volume in storage were stable or increased during periods of “dry” to “wet” water year types (Figures 2-3, 3-19 and 3-21). The Yucaipa GSA, at its discretion, may modify the 20% reduction (e.g., implement a higher percentage of reduction) if this rate is not sufficient to improve conditions in the management area.

4.2.1.2.1 Measurable Objective Expected to Benefit
The measurable objective established for the sustainability indicators of chronic lowering of groundwater levels, reduction in groundwater storage, and land subsidence would benefit from the implementation of this management action. The goal of the management action is to reduce the net use of groundwater from the management area by 5% to 20% of the estimated sustainable yield until conditions improve to the measurable objective where the management area is managed sustainably and no undesirable results are experienced. Currently, groundwater conditions in the Calimesa management area are managed sustainably.

4.2.1.2.2 Expected Benefits and Evaluation
The sustainability criteria established for the Calimesa management area were designed to protect the long-term groundwater supply and maintain production for the existing wells operated by South Mountain, South Mesa, YVWD, and private users. The establishment of a drought buffer, represented by a range in the volume in storage from 798,700 to 772,700 AF, provides operational flexibility for the Yucaipa GSA to implement these management actions to avoid or improve conditions from undesirable results. These actions allow the management area to recover during “dry“ to “wet” water year types when recharge will exceed the net withdrawal of groundwater.

Groundwater in storage will increase and chronic declines in groundwater elevations will cease or reverse with a net reduction in groundwater use from the management area. Groundwater in storage will be measured using groundwater elevations as a proxy. If groundwater elevations stabilize, or rise at the groundwater level RMPs, the management action will have succeeded in increasing the volume of groundwater in storage and prevented the chronic decline in groundwater levels. Conditions at the measurable objective or higher are at or above the historical Redlands Regular Meeting of 01-18-2022 Page 600 of 1274 ADMINISTRATIVE DRAFT – GROUNDWATER SUSTAINABILITY PLAN FOR THE YUCAIPA SUBBASIN CHAPTER 4 – PROJECTS AND MANAGEMENT ACTIONS

low, which will negate the undesirable result of land subsidence potentially occurring due to a long-term groundwater level decline below the historical low.

4.2.1.2.3 Circumstances for Implementation
This management action would be implemented under the following circumstances:

1. When groundwater levels measured at 50% or more of the RMPs fall below their respective measurable objective levels and drought buffer tiers for 2 consecutive years, or

2. When groundwater levels measured at 50% or more of the RMPs fall below their respective minimum threshold levels for 2 consecutive years.

4.2.1.2.4 Public Noticing
Public noticing is not required for this management action, which would be undertaken under the Yucaipa GSA’s authority to control groundwater withdrawals from the Calimesa management area. The Yucaipa GSA will notify private well owners that will be affected by the implementation of this management action if it requires a reduction in their respective groundwater production.

4.2.1.2.5 Permitting and Regulatory Process
No additional permitting or regulatory oversight is necessary to implement this management action, which would be undertaken under the Yucaipa GSA’s authority per Water Code, Section 10726.4.

4.2.1.2.6 Implementation Schedule
The YIHM predicts long-term fluctuations of groundwater elevations at the RMPs above the measurable objective until approximately 2058 when drier conditions prevail and groundwater levels experience a declining trend to the end of the 50-year planning and implementation horizon (Figures 4-2 to 4-14). The circumstance for implementing this management action when groundwater elevations at 50% or more of the RMPs decline below their respective tier 1 levels is predicted in 2066. This is based on predicted groundwater elevations at Hog Canyon 2, South Mesa 7, YVWD-10, YVWD-12, YVWD-49, USGS Equestrian Park #1, and USGS 6th Street #1 falling below their respective tier 1 levels by 2065 and remaining below those levels into 2067 (Figures 4-2, 4-6, 4-7, 4-9, 4-10, 4-11, and 4-13).

The Yucaipa GSA will implement this management action within six months from confirming the predicted declines in groundwater levels by reducing the net use of groundwater from the management area by 5%.

4.2.1.2.7 Legal Authority
Yucaipa GSA has the legal authority to operate and regulate the production from water supply wells in the Plan Area per Water Code, Section 10726.4; and to import surface water (e.g., SWP water) or other supplemental water to artificially recharge the Subbasin per Water Code, Section 10726.2. No additional legal authority is required.

4.2.1.2.8 Estimated Costs
The costs associated with the implementation of this management action have not yet been estimated. However, if this management action is implemented, then additional costs may be incurred by South Mountain, South Mesa, YVWD, or their respective customers, and private users to supply additional supplemental water, enact water Redlands Regular Meeting of 01-18-2022 Page 601 of 1274 ADMINISTRATIVE DRAFT – GROUNDWATER SUSTAINABILITY PLAN FOR THE YUCAIPA SUBBASIN CHAPTER 4 – PROJECTS AND MANAGEMENT ACTIONS

conservation programs, or other actions to meet water demands. The responsibilities for covering costs between the water purveyors and private users, if applicable, will be determined at the time of implementation and will depend on their respective action and/or program implemented to achieve the overall goal of reducing the net use of groundwater from the management area.

4.2.1.3 Western Heights Management Area
The Western Heights management area includes seven RMPs, each associated with groundwater elevations representing the measurable objective at 408,800 AF and the minimum threshold at 398,800 AF in storage (Table 3-5; Table 4-3). The measurable objective is represented by the historical low condition and indicates that no undesirable results are occurring in the management area.

The YIHM predicts that future groundwater elevations with groundwater production constrained to the estimated sustainable yield of 1,760 AFY will remain above the measurable objective levels associated with each RMP (Figures 3-40 to 3-46). However, the following conditions will trigger management actions to be implemented by the Yucaipa GSA should conditions decline below the measurable objective:
1) If groundwater elevations decline at 50% or more of the RMPs below their respective measurable objective levels for two consecutive years, then the following management action will be implemented:
a) The net use of groundwater from the Western Heights management area will be reduced under a two-tier structure depending on the volume of groundwater in storage below the historical low of 408,800 AF.

Actions to be implemented under the two-tier structure are as follows:

4-11 October 2021
i) The first tier, which begins at the historical low, extends from 408,800 to 403,800 AF, or the top 5,000 AF in the drought buffer (Figure 4-15). Groundwater elevations at the RMPs that represent the historical low (i.e., the top of tier 1) range from 1,727 to 1,750 feet NAVD88 (Table 4-3). If groundwater elevations decline at 50% or more of the RMPs below their respective tier 1 levels for two consecutive years, then a net reduction in groundwater use by 5% of the estimated sustainable yield of 1,760 AFY, or 90 AFY, is required. The Yucaipa GSA will implement this management action by either reducing groundwater production by 90 AFY, artificially recharging the aquifer with an additional 90 AFY of supplemental water, enacting water conservation programs or other programs that result in a net reduction of groundwater use by 90 AFY, or any combination of these actions that result in a net reduction of groundwater use by 90 AFY. Currently, no interim milestones are defined because the management area is managed sustainably and conditions are at the measurable objective. However, if conditions decline to this first tier in the drought buffer, then this management action would be implemented and the Yucaipa GSA will identify interim milestones at that time to evaluate progress in achieving groundwater sustainability.
ii) The second tier extends from 403,800 to 398,800 AF, or the bottom 5,000 AF in the drought buffer (Figure 4-15). Groundwater elevations at the RMPs that represent the top of tier 2 range from 1,716 to 1,736 feet NAVD88 (Table 4-3). If groundwater elevations decline at 50% or more of the RMPs below their respective tier 2 levels for two consecutive years, then a net reduction in groundwater use by 10% of the estimated sustainable yield of 1,760 AFY, or by 180 AFY, is required. The Yucaipa GSA will implement this management action by either reducing groundwater production by 180 AFY, artificially recharging the aquifer with an additional 180 AFY of supplemental water, enacting water conservation programs or other programs that result in a net reduction of groundwater use by 180 AFY, or any combination of these actions that result in a net reduction of groundwater use by 180 AFY. Currently, no interim milestones are defined because the management area is managed sustainably and conditions are at the measurable objective. However, if conditions decline to this second tier in the drought buffer, then this management action would be implemented and the Yucaipa GSA will identify interim milestones at that time to evaluate progress in achieving groundwater sustainability. b) The 5% to 10% net reduction in groundwater use, which may be achieved with a reduction in groundwater production from 1,760 AFY to 1,670 AFY (5% less) or 1,580 AFY (10% less), was selected because historical data indicated that when groundwater production was at these rates or less groundwater levels and the volume in storage were stable or increased during periods of “dry” to “wet” water year types (Figures 2-34, 3-37, and 3-38). The Yucaipa GSA, at its discretion, may modify the 5% to 10% reduction (e.g., implement a higher percentage of reduction) if these rates are not sufficient to improve conditions in the management area and avoid undesirable results.
c) Implementing this management action will also require the Yucaipa GSA to reevaluate and, possibly, recalibrate the YIHM to improve the accuracy of the model in predicting future conditions. This action will be implemented if the occurrence is outside the scheduled 5-year evaluation, which already includes a reevaluation of the YIHM.
2) If conditions continue to decline and groundwater elevations at 50% or more of the RMPs fall below their respective minimum threshold levels for two consecutive years, then the following management action will be implemented:
a) The net use of groundwater from the Calimesa management area will be reduced by 15% of the estimated sustainable yield of 1,760 AFY, or by 260 AFY. Groundwater elevations at the RMPs that represent the minimum threshold range from 1,695 to 1,714 feet NAVD88 (Table 4-3). The Yucaipa GSA will achieve Redlands Regular Meeting of 01-18-2022 Page 603 of 1274 ADMINISTRATIVE DRAFT – GROUNDWATER SUSTAINABILITY PLAN FOR THE YUCAIPA SUBBASIN CHAPTER 4 – PROJECTS AND MANAGEMENT ACTIONS
11507
4-12 October 2021
this management action by either reducing groundwater production by 260 AFY, artificially recharge the aquifer with an additional 260 AFY of supplemental water, enact water conservation programs or other programs that result in a net reduction of groundwater use by 260 AFY, or any combination of these actions that result in a net reduction of groundwater use by 260 AFY. Because the management area is not experiencing or is expected to experience conditions below the minimum threshold through the 50- year planning and implementation horizon, no interim milestones are defined in this GSP. However, if conditions do fall below the minimum threshold and this management action is implemented, then the Yucaipa GSA will identify interim milestones at that time to evaluate progress in improving conditions to achieve groundwater sustainability.
b) The 15% net reduction in groundwater use, which may be achieved with a reduction in groundwater production by 260 AFY from 1,760 AFY to 1,500 AFY, was selected because historical data indicated that, when groundwater production was at 1,500 AFY or less, groundwater levels and the volume in storage were stable or increased during periods of “dry” to “wet” water year types (Figures 2-34, 3-37, and 3-38). The Yucaipa GSA, at its discretion, may modify the 15% reduction (e.g., implement a higher percentage of reduction) if this rate is not sufficient to improve conditions in the management area.

4.2.1.3.1 Measurable Objective Expected to Benefit
The measurable objective established for the sustainability indicators of chronic lowering of groundwater levels, reduction in groundwater storage, and land subsidence would benefit from the implementation of this management action. The goal of the management action is to reduce the net use of groundwater from the management area by 5% to 15% of the estimated sustainable yield until conditions improve to the measurable objective where the management area is managed sustainably and no undesirable results are experienced. Currently, groundwater conditions in the Western Heights management area are managed sustainably.

4.2.1.3.2 Expected Benefits and Evaluation
The sustainability criteria established for the Western Heights management area were designed to protect the longterm groundwater supply and maintain production for the existing wells operated by WHWC and private users. The establishment of a drought buffer, represented by a range in the volume in storage from 408,800 to 398,800 AF, provides operational flexibility for the Yucaipa GSA to implement these management actions to avoid or improve conditions from undesirable results. These actions allow the management area to recover during “dry“ to “wet” water year types when recharge will exceed the net withdrawal of groundwater.

Groundwater in storage will increase and chronic declines in groundwater elevation will cease or reverse with a net reduction in groundwater use from the management area. Groundwater in storage will be measured using groundwater elevations as a proxy. If groundwater elevations stabilize, or rise at the groundwater level RMPs, the management action will have succeeded in increasing the volume of groundwater in storage and prevented a chronic decline in groundwater levels. Conditions at the measurable objective or higher are at or above the historical low, which will negate the undesirable result of land subsidence potentially occurring due to a long-term groundwater level decline below the historical low.

4-13 October 2021

4.2.1.3.3 Circumstances for Implementation
This management action would be implemented under the following circumstances:

1. when groundwater levels measured at 50% or more of the RMPs fall below their respective measurable objective levels and drought buffer tiers for two consecutive years, or

2. when groundwater levels measured at 50% or more of the RMPs fall below their respective minimum threshold levels for two consecutive years.

4.2.1.3.4 Public Noticing
Public noticing is not required for this management action, which would be undertaken under the Yucaipa GSA’s authority to control groundwater withdrawals from the Western Heights management area. The Yucaipa GSA will notify private well owners that will be affected by the implementation of this management action if it requires a reduction in their respective groundwater production.

4.2.1.3.5 Permitting and Regulatory Process
No additional permitting or regulatory oversight is necessary to implement this management action, which would be undertaken under the Yucaipa GSA’s authority per Water Code, Section 10726.4.

4.2.1.3.6 Implementation Schedule
The YIHM predicts that groundwater elevations at the RMPs will not decline to tier 1 of the drought buffer through the 50-year planning and implementation horizon (Figures 4-16 to 4-22). Predicted groundwater elevations will not decline to tier 1 levels at more than 50% of the RMPs; therefore, there is no specific implementation schedule for this management action. However, the Yucaipa GSA will implement this management action within six months of determining that one of the criteria for implementation described in Section 4.2.1.3.3 has been met.

4.2.1.3.7 Legal Authority
Yucaipa GSA has the legal authority to operate and regulate the production from water supply wells in the Plan Area per Water Code, Section 10726.4; and to import surface water (e.g., SWP water) or other supplemental water to artificially recharge the Subbasin per Water Code, Section 10726.2. No additional legal authority is required.

4.2.1.3.8 Estimated Costs
The costs associated with the implementation of this management action have not yet been estimated. However, if this management action is implemented, then additional costs may be incurred by WHWC, or its respective customers, to supply additional supplemental water, enact water conservation programs, or other actions to meet water demands while reducing the net use of groundwater from the management area.

4.2.1.4 San Timoteo Management Area
The San Timoteo management area includes six RMPs to characterize shallow groundwater elevations and evaluate whether groundwater production from the principal aquifer will cause significant and unreasonable effects on the interconnection between surface water and groundwater. GDEs have been identified along the reach of San Redlands Regular Meeting of 01-18-2022 Page 605 of 1274 ADMINISTRATIVE DRAFT – GROUNDWATER SUSTAINABILITY PLAN FOR THE YUCAIPA SUBBASIN CHAPTER 4 – PROJECTS AND MANAGEMENT ACTIONS
11507
4-14 October 2021
Timoteo Creek in the Plan Area and the following management actions are intended to protect the habitat sustained by surface water in the creek and the underlying shallow groundwater. No management actions were developed for the chronic lowering of groundwater elevations, reduction in groundwater storage, and land subsidence because no sustainability criteria were developed for these indicators (Sections 3.4.4 and 3.5.4).

A measurable objective was established for shallow groundwater levels at 20 feet bgs (Figure 3-48). The following management action will be implemented to prevent the significant and unreasonable effects to the interconnection of surface water and groundwater and to protect the GDEs sustained in the management area:
1) If groundwater levels decline at 50% or more of the RMPs below 20 feet bgs for two consecutive years, then the following management action will be implemented:
a) Confirm that the decline in the water table is a result of groundwater production from the principal aquifer.

This may include observing groundwater levels at the RMPs and measuring stream flow when the principal aquifer well(s) is operating, or designing and implementing an aquifer test to confirm the influence of groundwater production from the principal aquifer on stream flow and the groundwater table. Currently, only private users are extracting groundwater from this management area. The Yucaipa GSA will contact the private well owners to obtain information to assess whether pumping at a private well is the cause for the observed surface water flow and/or groundwater level declines. The Yucaipa GSA will request historical and projected pumping demands to better characterize conditions in this subarea and determine the extent of influence of pumping at the private well(s) on stream flow and shallow groundwater. b) If an aquifer test is conducted and confirms the influence of production from the principal aquifer on the surface water/groundwater interconnection and a subsequent drawdown of the water table, then production from the principal aquifer will be reduced to the extent that it no longer causes a significant and unreasonable effect.

4.2.1.4.1 Measurable Objective Expected to Benefit
The measurable objective established for the sustainability indicator of surface water/groundwater interconnection would benefit from the implementation of this management action. The goal of the management action is to prevent significant and unreasonable effects on GDEs sustained by the interaction of surface water and the underlying shallow groundwater. Currently, groundwater conditions in the San Timoteo management area are not experiencing undesirable results.

4.2.1.4.2 Expected Benefits and Evaluation
The sustainability criteria established for the San Timoteo management area were designed to protect the GDEs along San Timoteo Creek. This includes reducing groundwater production from the principal aquifer that directly influences stream flow in the creek and the underlying shallow groundwater that sustains the GDEs. YVWD monitors stream flow and shallow groundwater conditions along this reach of San Timoteo Creek as part of the HMP implemented in 2011 (Section 1.5.1.2). Monitoring includes collecting groundwater elevation data at shallow wells and evaluating habitat conditions via NDVI analysis along this reach of the creek. To date, HMP monitoring has indicated that significant fluctuations in groundwater levels and habitat conditions result from climatic conditions (i.e., prolong drought, large storm events) rather than by other potential factors like local groundwater production.

4.2.1.4.3 Circumstances for Implementation
This management action would be implemented under the following circumstances:

1. When groundwater levels measured at 50% of the RMPs fall below the measurable objective for 2 consecutive years.

4.2.1.4.4 Public Noticing
Public noticing is not required for this management action, which would be undertaken under the Yucaipa GSA’s authority to control groundwater withdrawals from the principal aquifer in the San Timoteo management area. The Yucaipa GSA will notify private well owners that will be affected by the implementation of this management action.

4.2.1.4.5 Permitting and Regulatory Process
No additional permitting or regulatory oversight is necessary to implement this management action, which would be undertaken under the Yucaipa GSA’s authority per Water Code, Section 10726.4.

4.2.1.4.6 Implementation Schedule
There is no specific implementation schedule for this management action. There is no indication of declining groundwater levels and stress on GDEs from the extraction of groundwater from the principal aquifer. The Yucaipa GSA will reach out to known and potential private well owners to obtain information on pumping schedules and volumes to better characterize conditions in this management area. This information will help inform the management action taken should groundwater elevations at three or more of the RMPs decline below the measurable objective.

4.2.1.4.7 Legal Authority
Yucaipa GSA has the legal authority to operate and regulate the production from water supply wells in the Plan Area per Water Code, Section 10726.4; and to import surface water (e.g., SWP water) or other supplemental water to artificially recharge the Subbasin per Water Code, Section 10726.2. No additional legal authority is required.

4.2.1.4.8 Estimated Costs
The costs associated with the implementation of this management action have not yet been estimated. Costs may be incurred by the Yucaipa GSA to reach out to the private well owners to collect the necessary information to better characterize conditions in this management area. If aquifer tests are required, then additional costs will be incurred by the Yucaipa GSA to conduct the tests, collect and analyze the test data, and develop an appropriate action or response based on the test data to ensure that no undesirable results occur in the management area. These costs will be assessed at the time such action is identified.

4.2.2 Management Action No. 2 – Sustainable Yield Pumping Allocations and Groundwater Replenishment
Groundwater sustainable yield pumping allocations will be assigned to YVWD and private water users in the North Bench Management Area, to South Mountain, South Mesa, YVWD and private water users in the Calimesa Management Area, and to WHWC in the Western Heights management area per the subsections below when this GSP is adopted. No sustainable yield pumping allocations were assigned in the San Timoteo management area at this time because the Yucaipa GSA needs to confirm the location and volume of private pumping from the principal aquifer and determine whether sustainable yield pumping allocations are appropriate to manage groundwater production in this management area. The pumping allocations are designed to regulate the annual volume of groundwater produced by each groundwater user and maintain the total groundwater produced at or below the estimated sustainable yields for these management areas. The sustainable yield pumping allocations will be reevaluated within three months (i.e., every December) of the end of a water year.

As an incentive to manage groundwater production at or below the sustainable yield pumping allocation, a groundwater user may earn pumping credits in the amount of the sustainable yield pumping allocation less the groundwater pumped. For example, if water purveyor A pumped 1,000 AF in a water year and the sustainable yield pumping allocation is 1,200 AFY, then water purveyor A earned a 200 AF pumping credit. The Yucaipa GSA will apply a 5-year rolling pumping credit system to keep account of the pumping credits earned by each water purveyor, meaning pumping credits that are earned and not used after 5 years will be lost. Pumping credits, if available, may be used to offset the volume of groundwater produced in excess of the sustainable yield pumping allocation to the extent that the credits equal the pumping exceedance. Any remaining deficit will be charged a replenishment fee. Any pumping credits remaining will carry over into the next water year under the 5-year rolling pumping credit system. The accounting of pumping credits will begin with the adoption of the GSP. The volume of water pumped per user will be accounted for on a monthly basis beginning February 2022. The initial assessment for pumping credits will occur at the conclusion of the 2022 WY, and then reassessed at the conclusion of subsequent water years. Pumping credits will be assigned to users that pump less than their respective sustainable yield pumping allocation, or a deficit will be assigned should the volume pumped exceed the sustainable yield pumping allocation. Pumping credits cannot be transferred or sold to another entity within a given management area or with the Subbasin.

As an alternative to using pumping credits to offset a pumping exceedance, a water purveyor may use surplus supplemental water that directly recharged the Subbasin (See Management Action No. 3, Section 4.2.3). If such water is available and accessible to the water purveyor, then this water may be used instead of pumping credits to offset the pumping exceedance.

The following provides a description of how the pumping allocations were assigned to each purveyor, and the management actions that will be implemented when a groundwater user exceeds their respective sustainable yield pumping allocation.

4.2.2.1 North Bench Management Area
YVWD and private users are the two groundwater users in the North Bench Management Area. From the 1966 WY to the 2018 WY, the average annual production rates for YVWD and private users were 2,647 AFY and 778 AFY, respectively (Figure 4-23, Table 4-4). Groundwater production by YVWD accounted for 77.3% of the total production, private users accounted for 22.7%. Applying these allocations to the estimated sustainable yield of 3,940 AFY for Redlands Regular Meeting of 01-18-2022 Page 608 of 1274 ADMINISTRATIVE DRAFT – GROUNDWATER SUSTAINABILITY PLAN FOR THE YUCAIPA SUBBASIN CHAPTER 4 – PROJECTS AND MANAGEMENT ACTIONS
11507
4-17 October 2021
the North Bench management area, the sustainable yield pumping allocations for YVWD and private users are 3,045 AFY and 895 AFY, respectively (Table 4-4).

Table 4-4. Sustainable Yield Pumping Allocations in the North Bench Management Area Groundwater User
Average Historical
Pumping (AFY)
Historical Pumping
Allocation (%)
Sustainable Yield
Pumping Allocation (AFY)
YVWD 2,647 77.3% 3,045
Private 778 22.7% 895
Total 3,425 100.0% 3,940
The volume of groundwater produced will be quantified per water year (October 1 to September 30) with the total volumes reported to the Yucaipa GSA by the end of the calendar year. If a groundwater user exceeds their respective sustainable yield pumping allocation, then the groundwater user will be charged a replenishment fee equivalent to the volume of groundwater that exceeds the sustainable yield pumping allocation multiplied by the rate per AF to purchase supplemental water at San Bernardino Valley Municipal Water District (SBVMWD) rates for imported SWP water. If the groundwater user has accrued pumping credits or has surplus supplemental water available in the aquifer, then the pumping credits or surplus supplemental water may be applied up to the pumping exceedance. If there continues to be a deficit, then a replenishment fee will be charged to the groundwater user. The supplemental water required under this management action will be purchased in the subsequent water year, if available, and used to artificially recharge and replenish the Subbasin at the Wilson Creek spreading basins.

The historical production by private users was based on data from the USGS that was incorporated into the YIHM.

Figure 4-23 indicates that groundwater production by private users has been steadily declining since the early 1980s to where the average rate over the last 10 years has been approximately 160 AFY. The Yucaipa GSA will make efforts to contact private well users in this management area to confirm the estimated rate of groundwater production per private user. This will provide the Yucaipa GSA with information to characterize the influence of each individual private user on conditions in the management area, and to apply the appropriate pumping allocation.

The sustainable yield pumping allocations between YVWD and private users will be reassessed when data on the current and projected usage by private users is collected and analyzed.

4.2.2.1.1 Measurable Objective Expected to Benefit
The measurable objective established for the sustainability indicators of chronic lowering of groundwater levels, reduction in groundwater storage, and land subsidence would benefit from the implementation of this management action.

4.2.2.1.2 Expected Benefits and Evaluation
The goal of this management action is to replenish the management area when groundwater withdrawals exceed the sustainable yield pumping allocation assigned to a groundwater user. This action will prevent long-term declines in groundwater elevations and storage due to groundwater production above the sustainable yield, and help prevent conditions from falling below the historical low in groundwater levels that potentially cause significant and unreasonable effects due to land subsidence. Currently, groundwater extractions from the North Bench management area are below the estimated sustainable yield of 3,940 AFY (Figure 3-3).

11507
4-18 October 2021
The benefit of this management action will be evaluated after the purchase of replenishment water and subsequent discharge to the Wilson Creek and Oak Glen Creek spreading basins to replenish the Subbasin.

4.2.2.1.3 Circumstances for Implementation
This management action would be implemented when the volume of groundwater produced by a water purveyor and/or private user per water year exceeds their respective sustainable yield pumping allocation, and the use of pumping credits and/or surplus supplemental water (Section 4.2.3) was insufficient to offset the pumping exceedance. The groundwater user will be required to purchase supplemental water in the subsequent water year for replenishment purposes via the Wilson Creek and Oak Glen Creek spreading basins. If no supplemental water is available, then the volume to replenish will be held in account for up to 5 years until water is available or the groundwater user has earned pumping credits to offset this exceedance. If after 5 years there is no supplemental water available to replenish the management area and the groundwater user has not earned pumping credits to offset the exceedance, then a reassessment of the sustainable yield and pumping allocations will be conducted for the management area.

4.2.2.1.4 Public Noticing
Public noticing is not required for this management action, which would be undertaken under the Yucaipa GSA’s authority to control groundwater production from the North Bench management area and acquire surface water to direct to spreading basins and/or other purposes per Water Code Sections 10726.2 and 10726.4.

4.2.2.1.5 Permitting and Regulatory Process
No additional permitting or regulatory oversight is necessary to implement this management action, which would be undertaken under the Yucaipa GSA’s authority per Water Code Sections 10726.2 and 10726.4.

4.2.2.1.6 Implementation Schedule
This management action requires the purchase of supplemental water for replenishment purposes in the subsequent water year after the management action is implemented and the application of pumping credits and/or surplus supplemental water, if any, do not offset the pumping exceedance. If no supplemental water is available to replenish the Subbasin in the subsequent water year, then the replenishment water volume will be held in account for up to 5 years until there is supplemental water available or pumping credits are earned to offset the pumping exceedance.

4.2.2.1.7 Legal Authority
Yucaipa GSA has the legal authority to operate and regulate the production from water supply wells in the Plan Area per Water Code, Section 10726.4; and to import surface water (e.g., SWP water) or other supplemental water per Water Code, Section 10726.2. No additional legal authority is required.

4.2.2.1.8 Estimated Costs
The costs associated with the implementation of this management action are based on the volume of groundwater in excess of the sustainable yield pumping allocation and the rate of SWP water by SBVMWD per acre-foot.

Additional costs may be incurred for the distribution and delivery to the Wilson Creek and Oak Glen Creek spreading basins. The estimated costs may vary annually depending on the rate charged by SBVMWD for supplemental water to replenish the Subbasin.

4-19 October 2021

4.2.2.2 Calimesa Management Area
The four groundwater users in the Calimesa Management Area are South Mountain, South Mesa, YVWD and private users. From the 1966 WY to the 2018 WY, the average annual production rates for South Mountain, South Mesa, YVWD and private users were 544 AFY, 2,056 AFY, 2,457 AFY and 143 AFY, respectively (Figure 4-24; Table 4-5).

Historically, groundwater production by South Mountain, South Mesa, YVWD and private users accounted for 10.5%,

39.5%, 47.2%, and 2.8%, respectively, of the average annual production of 5,200 AFY. Applying these allocations to the estimated sustainable yield of 4,955 AFY for the Calimesa management area, the sustainable yield pumping allocations for South Mountain, South Mesa, YVWD and private users are 518 AFY, 1,959 AFY, 2,341 AFY, and 137 AFY, respectively1 (Table 4-5).

Table 4-5. Sustainable Yield Pumping Allocations in the Calimesa Management Area Groundwater User

South Mountain 544 10.5% 518
Private 143 2.8% 137
Total 5,200 100.0% 4,955
The volume of groundwater produced will be quantified per water year (October 1 to September 30) with the total volumes reported to the Yucaipa GSA by the end of the calendar year. If a groundwater user exceeds their respective sustainable yield pumping allocation, then the groundwater user will be charged a fee equivalent to the volume of groundwater that exceeds their respective sustainable yield pumping allocation multiplied by the rate per AF of supplemental water supplied by SBVMWD and/or San Gorgonio Pass Water Agency (SGPWA) depending on the availability of supplemental water for purchase. The Calimesa management area straddles the boundary between San Bernardino County and Riverside County, which includes the service areas of SBVMWD and SGPWA. SWP water supplied by these two regionals may be available as a supplemental water source under this management action.

If a groundwater user has accrued pumping credits and/or surplus supplemental water that directly recharged the aquifer, then the pumping credits and/or surplus supplemental water may be applied to offset the pumping exceedance. If there continues to be a deficit, then a fee will be charged to the groundwater user to purchase supplemental water. The supplemental water will be purchased in the subsequent water year, if available, and used to artificially replenish the aquifer, if applicable, or as in lieu use to offset the pumping exceedance.

Currently, there are no spreading basins in the Calimesa management area, but the Yucaipa GSA member agencies are evaluating two potential sites to develop surface water spreading basins for the purposes of artificially recharging the Subbasin. The Yucaipa GSA will utilize the YIHM as a tool to evaluate the feasibility of operating spreading basis at the two proposed sites. The feasibility studies will evaluate the beneficial impact of recharging the aquifer at these two potential locations. In the meantime, the supplemental water may be used as in lieu use to offset the pumping exceedance.
1 In accordance with Water Code Section 10720.5, the sustainable yield allocations set forth in Management Action No. 2 are neither intended to nor actually comprise any determination of water rights.

4-20 October 2021
The historical production by private users was based on data from the USGS that was incorporated into the YIHM.

Figure 4-24 indicates that groundwater production by private users has been steady at approximately 200 AFY since 2000. The Yucaipa GSA will make efforts to contact private well users in this management area to confirm the locations and estimated rates of groundwater extraction for the active private groundwater users. The sustainable yield pumping allocations between the water purveyors and individual private users will be reassessed when data on the current and projected usage by private users is collected and analyzed.

4.2.2.2.1 Measurable Objective Expected to Benefit
The measurable objective established for the sustainability indicators of chronic lowering of groundwater levels, reduction in groundwater storage, and land subsidence would benefit from the implementation of this management action.

4.2.2.2.2 Expected Benefits and Evaluation
The goal of this management action is to replenish the management area or reduce groundwater withdrawals when groundwater production exceeds the sustainable yield pumping allocation assigned to a groundwater user. This action will prevent long-term declines in groundwater elevations and storage due to groundwater production above the sustainable yield, and help prevent conditions from falling below the historical low in groundwater levels that potentially cause significant and unreasonable effects due to land subsidence. Currently, groundwater extractions from the Calimesa management area are below the sustainable yield of 4,955 AFY (Figure 3-19). Because there are no spreading basins in the Calimesa management area, the supplemental water may be used as in lieu use to offset the pumping exceedance.

4.2.2.2.3 Circumstances for Implementation
This management action would be implemented when the volume of groundwater produced by a water purveyor and/or private user per water year exceeds their respective sustainable yield pumping allocation. The groundwater user will be assessed a fee to purchase supplemental water if the application of pumping credits and/or surplus supplemental water, if available, do not offset the production exceedance. If no supplemental water is available to replenish the aquifer, then the volume to replenish will be held in account for up to 5 years until water is available or the groundwater user has earned pumping credits to offset this exceedance. If after 5 years there is no supplemental water available and the groundwater user has not earned pumping credits to offset the exceedance, then a reassessment of the sustainable yield and pumping allocations will be conducted for the management area.

4.2.2.2.4 Public Noticing
Public noticing is not required for this management action, which would be undertaken under the Yucaipa GSA’s authority to control groundwater production from the Calimesa management area and acquire surface water to import into the Plan Area per Water Code Sections 10726.2 and 10726.4.

4.2.2.2.5 Permitting and Regulatory Process
No additional permitting or regulatory oversight is necessary to implement this management action, which would be undertaken under the Yucaipa GSA’s authority per Water Code Sections 10726.2 and 10726.4.

4-21 October 2021

4.2.2.2.6 Implementation Schedule
This management action requires the purchase of supplemental water in the subsequent water year after the management action is implemented and the application of pumping credits and/or surplus supplemental water, if any, do not offset the pumping exceedance. If no supplemental water is available in the subsequent water year to replenish the aquifer, then the supplemental water volume will be held in account for up to 5 years until there is supplemental water available or pumping credits are earned to offset the pumping exceedance.

4.2.2.2.7 Legal Authority
Yucaipa GSA has the legal authority to operate and regulate the production from water supply wells in the Plan Area per Water Code, Section 10726.4; and to import surface water (e.g., SWP water) or other supplemental water per Water Code, Section 10726.2. No additional legal authority is required.

4.2.2.2.8 Estimated Costs
The costs associated with the implementation of this management action are based on the volume of supplemental water required to offset the pumping exceedance after pumping credits and/or surplus supplemental water, if any, have been applied. The cost for supplying supplemental water for replenishment purposes or as in lieu water will be based on the rate of SWP water per AF by SBVMWD and/or SGPWA. Additional costs may be incurred for the distribution and delivery of supplemental water to the management area. The estimated costs may vary annually depending on the rate charged by the Regionals for supplemental water.

4.2.2.3 Western Heights Management Area
WHWC is the only groundwater user in the Western Heights Management Area. The sustainable yield pumping allocation to WHWC is the sustainable yield of 1,760 AFY. The volume of groundwater produced will be quantified per water year (Oct. 1 to Sep. 30) with the total volume reported to the Yucaipa GSA by the end of the calendar year.

If WHWC exceeds the sustainable yield, then WHWC will be charged a fee equivalent to the volume of groundwater that exceeds the sustainable yield multiplied by the rate per AF to purchase supplemental water at SBVMWD rates for imported SWP water. The supplemental water will be purchased in the subsequent water year, if available, and used as in lieu water to offset the pumping exceedance in the subsequent water year. There are no spreading basins in the Western Heights management area to receive SWP water.

4.2.2.3.1 Measurable Objective Expected to Benefit
The measurable objective established for the sustainability indicators of chronic lowering of groundwater levels, reduction in groundwater storage, and land subsidence would benefit from the implementation of this management action.

4.2.2.3.2 Expected Benefits and Evaluation
The goal of this management action is to replenish the management area or reduce groundwater withdrawals when groundwater production exceeds the sustainable yield. This action will prevent long-term declines in groundwater elevations and storage due to groundwater production above the sustainable yield, and help prevent conditions from falling below the historical low in groundwater levels that potentially cause significant and unreasonable effects due to land subsidence. Currently, groundwater extractions from WHWC in the Western Heights management area are below the sustainable yield of 1,760 AFY (Figure 3-37).

4.2.2.3.3 Circumstances for Implementation
This management action would be implemented when the volume of groundwater produced by WHWC per water year exceeds the sustainable yield. WHWC will be assessed a fee to purchase supplemental water if WHWC cannot apply pumping credits to offset the production exceedance. If no supplemental water is available, then the volume of supplemental water will be held in account for up to 5 years until water is available or the groundwater user has earned pumping credits to offset this exceedance. If after 5 years there is no supplemental water available and the groundwater user has not earned pumping credits to offset the exceedance, then a reassessment of the sustainable yield and pumping allocations will be conducted for the management area.

4.2.2.3.4 Public Noticing
Public noticing is not required for this management action, which would be undertaken under the Yucaipa GSA’s authority to control groundwater production and acquire surface water to import into the Plan Area per Water Code Sections 10726.2 and 10726.4.

4.2.2.3.5 Permitting and Regulatory Process
No additional permitting or regulatory oversight is necessary to implement this management action, which would be undertaken under the Yucaipa GSA’s authority per Water Code Sections 10726.2 and 10726.4.

4.2.2.3.6 Implementation Schedule
This management action requires the purchase of supplemental water as in lieu water in the subsequent water year after the management action is implemented. If no supplemental water is available, then the volume of supplemental water will be held in account for up to 5 years until there is supplemental water available or a reevaluation of the sustainable yield is conducted at the end of the 5-year limit.

4.2.2.3.7 Legal Authority
Yucaipa GSA has the legal authority to operate and regulate the production from water supply wells in the Plan Area per Water Code, Section 10726.4; and to import surface water (e.g., SWP water) or other supplemental water per Water Code, Section 10726.2. No additional legal authority is required.

4.2.2.3.8 Estimated Costs
The costs associated with the implementation of this management action are based on the volume of groundwater produced in excess of the sustainable yield and the rate of SWP water by SBVMWD per acre-foot. Additional costs may be incurred for the distribution and delivery to the Western Heights management area. The estimated costs may vary annually depending on the rate charged by SBVMWD for supplemental water to replenish the Subbasin.

4.2.2.4 San Timoteo Management Area
This management action does not apply to the San Timoteo Management Area.

4.2.3 Management Action No. 3 – Surplus Supplemental
Water Spreading
YVWD has purchased SWP water, when available, to artificially recharge the Subbasin via the Wilson Creek and Oak Glen Creek spreading basins (Section 2.5.4.2; Figure 2-21). This water has helped contribute to the recovery of the North Bench management area since it was first used to artificially recharge the Subbasin in 2011. The Yucaipa GSA will continue to obtain, when available, surplus supplemental water to artificially recharge the Subbasin to help maintain groundwater in storage above historical lows.

Surplus supplemental water, which is not associated with Management Action No. 2 (Section 4.2.2), and discharged to a spreading basin to facilitate the artificial recharge of the Subbasin will have a separate accounting by the Yucaipa GSA. The surplus supplemental water will be accessible to the water purveyor that purchased the water and percolated it at a spreading basin. This water will be available to help offset production exceedances above the sustainable yield pumping allocations instead of pumping credits earned via Management Action No. 2.

The Yucaipa GSA will conduct a study within the first year of adopting the GSP to estimate the amount of water lost from the point of discharge at a spreading basin to the water table. This study will estimate monthly losses due to evaporation of water from a spreading basin to water retained in the soil column between the bottom of a spreading basin and the underlying water table. The estimate of water loss will be applied to the volume of surplus supplemental water discharged on a monthly basis to a spreading basin. Monthly estimates of water loss are appropriate because evaporative losses in the summer are higher than in the winter. The remaining water will directly recharge the aquifer and be available to the water purveyor that purchased the water. The study will include the existing spreading basins and stormwater capture basins, and proposed basins that may be constructed in the Subbasin. Potential basins in the Calimesa management area would be evaluated to assess the effect of artificial recharge on the projected declines in groundwater in storage under the Future Baseline with Climate Change II scenario.

The YIHM was used to simulate the flow of water from the Wilson Creek and Oak Glen Creek spreading basins over the 50-year implementation and planning horizon. The YIHM indicated that water originating from these two spreading basins will remain in the North Bench Management Area over the 50-year period. The YIHM also indicated that water originating at the locations of two potential basins in the Calimesa management area would remain in the management area. Consequently, the accounting of surplus supplemental water that directly recharges the aquifer does not include additional losses when the water is in the aquifer.

4.2.3.1 Measurable Objective Expected to Benefit
The measurable objective established for the sustainability indicators of chronic lowering of groundwater levels, reduction in groundwater storage, and land subsidence would benefit from the implementation of this management action.

4.2.3.2 Expected Benefits and Evaluation
This management action provides the Yucaipa GSA with an accounting methodology to purchase surplus supplemental water and directly recharge the Subbasin. This water will be accessible to the water purveyor that Redlands Regular Meeting of 01-18-2022 Page 615 of 1274 ADMINISTRATIVE DRAFT – GROUNDWATER SUSTAINABILITY PLAN FOR THE YUCAIPA SUBBASIN CHAPTER 4 – PROJECTS AND MANAGEMENT ACTIONS

4-24 October 2021
purchased the water and directed it to a spreading basin. The water may be used to help offset pumping exceedances over the sustainable yield pumping allocation.

4.2.3.3 Circumstances for Implementation
This management action would be implemented when a water purveyor purchases surplus supplemental water and directly recharges the Subbasin.

4.2.3.4 Public Noticing
Public noticing is not required for this management action, which would be undertaken under the Yucaipa GSA’s authority to acquire surface water to import into the Plan Area per Water Code Section 10726.2.

4.2.3.5 Permitting and Regulatory Process
No additional permitting or regulatory oversight is necessary to implement this management action at existing spreading basins, which would be undertaken under the Yucaipa GSA’s authority per Water Code Section 10726.2.

New spreading basins or direct injection wells would require permitting and regulatory process services before installation and use. The Yucaipa GSA will complete the appropriate permitting and regulatory requirements to facilitate the design, installation, and operations of new facilities in order to enhance the recharge of surplus supplemental water in the Subbasin.

4.2.3.6 Implementation Schedule
This management action will be implemented when surplus supplemental water is available and purchased to directly recharge the Subbasin.

4.2.3.7 Legal Authority
Yucaipa GSA has the legal authority to import surface water (e.g., SWP water) or other supplemental water per Water Code, Section 10726.2. No additional legal authority is required.

4.2.3.8 Estimated Costs
The costs associated with the implementation of this management action are based on the volume of surplus supplemental water purchased from the regionals and the costs for directing the water to spreading basins to artificially recharge the Subbasin. The estimated costs may vary annually depending on the rate charged by SBVMWD and/or SGPWA for surplus supplemental water to replenish the Subbasin.

4.3 Projects
Currently, the Plan Area is not experiencing undesirable results with regard to the chronic lowering of groundwater elevations, reduction of groundwater in storage, land subsidence, and depletion of surface water as a result of groundwater production from the principal aquifer that threatens GDEs. The importation of SWP water as a Redlands Regular Meeting of 01-18-2022 Page 616 of 1274 ADMINISTRATIVE DRAFT – GROUNDWATER SUSTAINABILITY PLAN FOR THE YUCAIPA SUBBASIN CHAPTER 4 – PROJECTS AND MANAGEMENT ACTIONS
11507
4-25 October 2021
supplemental source of water has allowed the Yucaipa GSA member agencies to reduce groundwater production in the North Bench, Calimesa and Western Heights management areas to levels below their respective estimated sustainable yields. Groundwater production by private well owners in the San Timoteo management area has not caused significant and unreasonable effects related to the sustainability indicators per the Sustainable Groundwater Management Act. The Subbasin is currently managed sustainably.

Measurable objectives defined for the North Bench, Calimesa and Western Heights management areas were based on volumes of groundwater in storage that represent historical low conditions (Calimesa and Western Heights) or conditions that are above historical lows (North Bench). The measurable objective defined for the San Timoteo management area was based on the presence of GDEs and maintaining a water table elevation within 20 feet below ground surface to sustain the GDEs.

Management actions (Section 4.2) were defined to achieve sustainable management of the groundwater resources in the Plan Area should groundwater elevations decline below measurable objectives. These actions will be implemented if groundwater levels decline to the drought buffers established for the North Bench, Calimesa and Western Heights management areas. The drought buffers provide operational flexibility for the Yucaipa GSA to implement these management actions and/or other programs to prevent undesirable results.

Some of the member agencies of the Yucaipa GSA have constructed stormwater capture basins to enhance recharge to the Subbasin (Table 4-6). The Wilson Creek and Oak Glen Creek spreading basins are designed to capture stormwater and are used to artificially recharge the Subbasin using surplus SWP water delivered by the SWP East Branch Extension. These basins are included in the YIHM to simulate their contributions to recharge to the Subbasin. The Wilson Creek and Oak Glen Creek basins have contributed an average 1,900 AFY and 170 AFY, respectively, of SWP water since 2011 (Table 2C-5). The other existing stormwater capture basins are estimated to capture approximately 1,800 AFY (Section 5.xxx). Recharge at these basins was not included in the future water budget analyses for the North Bench and Western Heights management areas using the YIHM, because these management areas are sustainably managed and are projected to not experience undesirable results over the 50- year planning and implementation horizon.

The Yucaipa GSA identified proposed projects that have been designed, permitted, and are undergoing development or will in the near future. These include the Wilson Creek III Basins, the Pendleton Avenue Low Water Crossing, and the Upper Wildwood Creek Basin (Table 4-7). These basins are designed to capture stormwater flows and enhance recharge to the Subbasin. The estimated average annual recharge contribution is approximately 1,500 AF. These basins will be located in the North Bench management area. As with the existing basins, these planned basins were not included in the future water budget analyses for the North Bench management area using the YIHM, because the North Bench management area is not projected to experience undesirable results over the 50-year planning and implementation horizon.

The Yucaipa GSA is evaluating potential sites to construct and operate spreading basins to enhance recharge in the Calimesa management area. The YIHM predicts that groundwater elevations will decline below the measurable objective under the Future Baseline with Climate Change II scenario within the 50-year planning and implementation horizon. Therefore, in addition to the management actions described in Section 4.2.1..2, the potential construction of one or two spreading basins will benefit users in this management area. The Yucaipa GSA will evaluate the proposed basin(s) after more details of their construction and operation are developed. The basins will be included in the YIHM and evaluated during the 5-year evaluation study after this GSP is adopted.

5 Plan Implementation

5.1 Introduction to Plan Implementation
Upon adoption of this GSP by the Yucaipa GSA, the primary activities associated with implementing the GSP include administrative duties by the member agencies of the Yucaipa GSA, the management of data collection, data validation, and analysis to evaluate conditions in the Subbasin, the preparation and submittal of annual reports and periodic evaluations, with associated data, to DWR, and an assessment of conditions in the Subbasin and determination if management actions need to be implemented. During the initial 5-year period after the GSP is adopted, the Yucaipa GSA will evaluate options to address data gaps identified in Section 2.6.3, and conduct feasibility studies to evaluate the effectiveness of potential spreading basins and other programs that would maintain or achieve sustainability in the Subbasin.

5.2 GSP Administration
The Yucaipa GSA is responsible for implementing the GSP after it is adopted. The administrative duties of the Yucaipa GSA include, at a minimum, the following:
• Adhering to the implementation schedule (Figure 5-1) to ensure that the Yucaipa GSA conducts the required minimum data collection periods in the Spring and Fall every year, the annual reports are prepared and submitted to DWR by April 1, and the periodic evaluation reports are submitted at least every 5 years or when the GSP is amended.
• Facilitate access to all wells and stream flow gauging stations in the monitoring network, including the RMPs in each management area, to ensure the collection of representative data by following the monitoring protocols presented in Section 3.6.4.
• Validate and upload data to the DMS for the purposes of evaluating conditions in the Plan Area. • Facilitate the submission of annual reports and periodic evaluation reports per Sub article 7 of Article 5 of the California Code of Regulations Division 2 Chapter 1.5 (23 California Code of Regulations, Section 356).

This section describes the procedures and requirements for preparing and submitting the annual reports and periodic evaluations to DWR.
• Facilitate public engagement.

The costs associated with administering the GSP will be shared per the MOA (Appendix 1-B). The MOA established a cost share structure with the water purveyors responsible for 75% and the San Bernardino Valley Municipal Water District and San Gorgonio Pass Water Agency (Regionals) and the Municipalities responsible for 25% of the costs associated with the administration of the Yucaipa GSA and the development and implementation of the GSP. In general, Yucaipa GSA plans to fund operating costs by using general operating funds, charging its customers through water rates, and/or fees assessed to new developments to connect to existing water services (public water supply, sanitary sewer). The estimated annual costs for implementing the GSP, including the estimated share in costs for each water purveyor and each Municipality and Regional, are summarized in Table 5-1.

5.3 Data Collection, Validation, and DMS
Member agencies of the Yucaipa GSA will continue participating in monitoring programs already implemented (Section 1.5.1) to collect groundwater elevation, groundwater quality, and production data to characterize conditions in the Subbasin. The member agencies will follow the monitoring protocols presented in Section 3.6.4 to collect data that is accurate and representative of conditions in the Subbasin, and will upload the data to the DMS. As discussed in Section 3.6, the monitoring schedule to collect static groundwater elevation data, at a minimum, is March 9 to 22 for the spring and October 9 to 22 for the fall. The recommended frequency to collect static groundwater elevation data is monthly. Water quality data is collected per the monitoring requirements under Title 22 for municipal water supply wells and the MBMP, and water quality sampling will follow the monitoring protocols presented in Section 3.6.4.3.

The water purveyors use calibrated flow meters and totalizers to track the volume of groundwater extracted at their respective municipal and irrigation water supply wells. Production data is collected on a monthly basis. Precipitation gauges have been maintained and monitored by the SBCFCD and the USGS, both of which are public agencies that provide their respective data in the public domain. The Yucaipa GSA will access this data and upload it to the DMS.

During the initial 5-year period after the GSP is adopted, the Yucaipa GSA will evaluate options for filling data gaps identified in this GSP. The primary data gaps identified were a lack of knowledge of existing private well users operating in the Subbasin, spatial gaps in groundwater elevation data in the eastern section of the Calimesa management area, and stream flow gauging stations to measure low to normal flows. As discussed in Section 3.6.6, the Yucaipa GSA will make efforts to obtain information on private well users, improve existing or install new stream flow gauging stations to enhance the characterization of stream flow in the Plan Area, and improve the spatial and temporal monitoring coverage of the Subbasin. For instance, pressure transducers may be installed at some wells in the monitoring network to reduce the time-window over which groundwater elevations are manually collected.

The costs of obtaining information from private well users, improving the monitoring of surface water flows, and addressing data gaps in the monitoring network are associated with GSP implementation.

5.4 Annual Reports
Sub article 7 of Article 5 of the California Code of Regulations Division 2 Chapter 1.5 (23 CCR, Section 356.2) describes the general requirements for the annual reports to be submitted to DWR after the GSP is adopted by the Yucaipa GSA. Annual reports are due to DWR by April 1 of each year following the adoption of the GSP. Each annual report shall include the following components:
• General information, including an executive summary and a location map depicting the basin, jurisdictional boundaries, and Plan Area covered by the report.
• A detailed description and graphical representation of:
o Groundwater elevation data from wells identified in the monitoring network, o Groundwater elevation contour maps depicting, at a minimum, the seasonal high and seasonal low groundwater elevations observed in the preceding year,
o Groundwater elevation hydrographs depicting historical trends updated with data collected in the preceding year,
o Groundwater extractions for the preceding water year, o An accounting of surface water supply, including imported SWP water, imported groundwater from outside the Plan Area, and surface water diversions,
o An accounting of total water use and identity of the water use sector, o Change in groundwater in storage,
• A description of progress toward implementing the GSP, including implementation of projects or management actions since the previous annual report.

The description and graphical representation of the change in groundwater storage will include a graph depicting water year type, based on the annual precipitation in the Plan Area compared to the mean annual rainfall (Section

2.2.1.4), groundwater production, the annual change in groundwater in storage, and the cumulative change in groundwater in storage for the Plan Area based on the simulated annual change in storage by the YIHM. The annual reports will conclude with an overview of the implementation of the GSP, including an evaluation of groundwater conditions against the sustainability criteria established in Chapter 3. The annual report will include a descriptive summary of any management actions that were implemented in the Plan Area.

5.5 Periodic Evaluations
Every fifth year of GSP implementation and whenever the GSP is amended, the Yucaipa GSA is required to prepare and submit an Agency Evaluation and Assessment Report to DWR together with the annual report for that year (23 CCR, Section 356.4). The tasks associated with preparing this report include evaluating any new information that has been made available since the GSP adoption and assessing whether changes to assumptions or descriptions in the GSP are required. The following components are required in the periodic evaluation reports:
• A description of current groundwater conditions for each applicable sustainability indicator relative to measurable objectives and minimum thresholds.
• A description of the implementation of any projects or management actions, and the effect on groundwater conditions resulting from those projects or management actions.

• A review and evaluation of the Plan Area setting, management areas, sustainability criteria and management actions described in the GSP, and proposed revisions to the GSP based on information obtained since the adoption of the Plan.
• A description and evaluation of the monitoring network within the Plan Area. The evaluation will determine if data gaps identified in the GSP have been addressed, and if new data gaps are identified. The periodic evaluation will include proposed actions by the Yucaipa GSA to address data gaps, which may include modifications to or expansion of the existing monitoring network. • A description of significant new information that has been made available since the adoption of the GSP, an amendment to the GSP, or the last 5-year assessment. • A description of relevant actions taken by the Yucaipa GSA, including a summary of regulations or ordinances related to management of the Plan Area or the GSP.
• Information describing any enforcement or legal actions taken by the Yucaipa GSA in furtherance of the sustainability goal for the Plan Area.
• A description of completed or proposed GSP amendments. • A reevaluation of the estimated sustainable yield of the Subbasin and the management areas by updating the YIHM with data collected since the last periodic evaluation.

5.6 GSP Implementation Schedule
The Yucaipa GSA has developed a schedule that outlines the approximate times at which the various monitoring and reporting components of the GSP will be implemented over the next 5 years (Figure 5-1). The actual start dates may vary from those shown in the schedule.

Guidance Document for the Sustainable Management of Groundwater Preparation Checklist for GSP Submittal
December 2016
The objective of this Guidance Document is to provide Groundwater Sustainability Agencies (GSAs) and other interested stakeholders a checklist of Groundwater Sustainability Plan (GSP) content requirements for the purpose of verifying a GSP is complete and is ready for submission to DWR. Please note that if multiple GSAs develop multiple GSPs for a basin, the coordinated submission of those GSPs shall not occur until the entire basin is covered by GSPs.

The Preparation Checklist for GSP Submittal is only intended to provide a guide to GSAs and other stakeholders. This guidance is optional, since the content of this Guidance Document does not create any new requirements or obligations for the GSA or other stakeholders.

Guidance documents are not a substitute for the GSP Emergency Regulations (GSP Regulations) or the Sustainable Groundwater Management Act (SGMA). Those GSAs submitting a GSP are strongly encouraged to read the GSP Regulations and SGMA. In addition, using this Guidance Document to develop a GSP using does not equate to an approval determination by DWR.

Context with GSP Regulations
The Preparation Checklist for GSP Submittal can be used by GSAs in conjunction with the GSP Annotated Outline Guidance Document as a method to develop a GSP consistent with the requirements of the GSP Regulations and SGMA. The detailed requirements of a GSP may be found in the GSP Regulations, primarily in Article 5 – Plan Contents, and in SGMA, primarily in Chapter 6 beginning with California Water Code (CWC) Section 10727. The checklist includes references to applicable GSP Regulations sections and CWC sections, as well as a brief description of the required GSP information. The checklist also contains a column for GSAs to record the page number, or section of the GSP, where the information for that particular requirement is found.

The preparation checklist may also be included in the GSP.

Table 1 contains the Preparation Checklist for GSP Submittal.

Re : Support for Yucaipa Sub-Basin Groundwater Sustainability Agency Mr. Headrick:

On May 23, 2017, the County of San Bernardino Board of Supervisors voted to communicate the County's support of the cooperative efforts of the Yucaipa Sub-Basin Groundwater Sustainability Agency to manage groundwater in the Yucaipa Sub-Basin (No. 8-2.07) in compliance with the California Sustainable Groundwater Management Act.

The County appreciates the commitment of the cities of Calimesa, Redlands and Yucaipa; San Bernardino Valley Municipal Water District; San Gorgonio Pass Water Agency; Yucaipa Valley Water District; South Mesa Water Company; South Mountain Water Company; and Western Heights Water Company to maintain local control of the Yucaipa Sub-Basin and to work together through a Memorandum of Agreement to sustainably manage the basin's groundwater resources in a way that considers the interests of all beneficial uses and users.

As the County is also eligible to serve as the Groundwater Sustainability Agency for the Yucaipa Sub-Basin, the County wishes to assure you that the County does not intend to adopt a competing Groundwater Sustainability Agency formation resolution and notification of the California Department of Water Resources. To that end, on March 7, 2017, the Board of Supervisors adopted a resolution that the County would not be the Groundwater Sustainability Agency for 11 groundwater basins and sub-basins in the county, including Yucaipa Sub-Basin. A copy of this resolution is attached .

If you shou ld have any questions, please contact Bob Page, Principal Management Analyst, at {909) 387-4384 or by email at [email protected]. Thank you .

County Administrative Office
SUBJECT: SUPPORT FOR BEAR VALLEY BASIN AND YUCAIPA BASIN

GROUNDWATER SUSTAINABILITY AGENCIES
RECOMMENDATION($)

1. Approve and authorize submission of letters of support for the cooperative efforts of cities, water districts and water companies to manage groundwater in compliance with the California Sustainable Groundwater Management Act in the following groundwater basins:
a. Bear Valley Basin (No. 8-9)
b. Yucaipa Sub Basin (No. 8-2.07)

2. Authorize the Chairman of the Board of Supervisors or the Chief Executive Officer to execute similar letters of support, subject to review by County Counsel, for local agency efforts to manage other groundwater basins in San Bernardino County that must comply with the California Sustainable Groundwater Management Act for which the County has previously notified the California Department of Water Resources that the County will not serve as the Groundwater Sustainability Agency.
(Presenter: Bob Page, Principal Management Analyst, 387-5425)

COUNTY AND CHIEF EXECUTIVE OFFICER GOALS AND OBJECTIVES Ensure Development of a Well-Planned, Balanced, and Sustainable County.

Pursue County Goals and Objectives by Working with Other Agencies.

FINANCIAL IMPACT
Providing letters of support to local agencies forming Groundwater Sustainability Agencies (GSAs) will not result in the use of additional Discretionary General Funding (Net County Cost).

BACKGROUND INFORMATION
Effective January 1, 2015, the California Sustainable Groundwater Management Act (SGMA) requires local water and land use agencies to sustainably manage 127 groundwater basins and sub-basins (basins) that have been designated by the California Department of Water Resources (DWR) as medium or high priority. SGMA mandates that one eligible local agency or multiple eligible local agencies form a GSA for each of these basins by June 30, 2017 with the responsibility of developing and implementing a Groundwater Sustainability Plan (GSP). cc: CAO-Smith

SUPPORT FOR BEAR VALLEY BASIN AND YUCAIPA BASIN

GROUNDWATER SUSTAINABILITY AGENCIES
MAY 23, 2017
PAGE 2 OF 3
DWR has designated Bear Valley Basin as medium priority. DWR has also defined the boundaries of the Bear Valley Basin in its Bulletin 118 and assigned it No. 8-9. The City of Big Bear Lake, the Big Bear City Community Services District and the Big Bear Municipal Water District have formed the Bear Valley Basin Groundwater Sustainability Agency (Bear Valley Basin GSA), a joint powers authority that became effective on April 26, 2017, with the purpose to become the exclusive GSA for the Bear Valley Basin.

DWR has designated Yucaipa Sub-Basin as medium priority. DWR has also defined the boundaries of the Yucaipa Sub-Basin in its Bulletin 118 and assigned it No. 8-2.07. Negotiations of a Memorandum of Agreement (MOA) regarding the formation of a GSA for the Yucaipa SubBasin completed in April. The MOA was circulated for approval by June from the governing bodies of the following parties to the MOA: the cities of Calimesa, Redlands and Yucaipa; San Bernardino Valley Municipal Water District; San Gorgonio Pass Water Agency; Yucaipa Valley Water District; South Mesa Water Company; South Mountain Water Company; and Western Heights Water Company.

Before either GSA can be the exclusive GSA for their respective basin, SGMA requires that they hold a noticed public hearing to adopt a resolution to become the exclusive GSA The Bear Valley Basin GSA hearing is scheduled for May 25, 2017. The parties to Yucaipa Sub-Basin GSA MOA will hold separate public hearings on various dates before June 30, 2017. The GSAs will then have 30 days to notify DWR of their decisions, providing among other things a map of the service areas of the parties within each basin (attached) and a list of all beneficial uses and users of the groundwater and how their interests will be considered in the operation of the GSAs and the development and implementation of their GSPs.

DWR will post the notices on its SGMA Portal on its website (sgma.water.ca.gov/portal/#intro).

Other eligible local agencies in each basin, including the County, will then have 90 days to file a competing GSA notice. If no competing notices are filed with DWR, the Bear Valley Basin GSA and Yucaipa Sub-Basin GSA will become the exclusive GSAs for their basins. On March 7, 2017 (Item No. 20), the Board of Supervisors (Board) adopted a resolution that the County would not be the GSA for 11 groundwater basins and sub-basins in the county, including Bear Valley Basin and Yucaipa Sub-Basin. The Board adopted a simitar resolution covering five other basins on January 10, 2017 {Item No. 21).

The parties to these GSAs requested that the County support their efforts. If approved by the Board, the recommended letters will be provided to the Bear Valley Basin GSA and Yucaipa SubBasin GSA.

If local agencies in any of the other 14 basins covered by the Board's January 10 and March 7 resolutions request support of their GSA, approval of Recommendation No. 2 will authorize the Chairman of the Board or the Chief Executive Officer to execute similar letters of support, subject to review by County Counsel.

1 BACKGROUND OF THE SUSTAINABLE GROUNDWATER

MANAGEMENT ACT
The Sustainable Groundwater Management Act, signed into law by Governor Jerry Brown on September 16, 2014, created a new framework for groundwater management in California. The framework includes a structure and schedule to achieve sustainable groundwater management within 20 years. The California Department of Water Resources (DWR) has historically managed the state’s central repository for groundwater data. Under The Sustainable Groundwater Management Act, DWR provides guidance, financial assistance, and technical support for compliance with state requirements. The State Water Resources Control Board (SWRCB) provides the regulatory backstop under The Sustainable Groundwater Management Act, taking over basin management and assessing fees if local groundwater management is not successful in complying with the requirements of The Sustainable Groundwater Management Act.

The Sustainable Groundwater Management Act established a new structure for local groundwater management through Groundwater Sustainable Agencies (GSAs). The formation of GSAs for all basins that the DWR designated as high and medium priority groundwater basins was required by July 1, 2017. Each GSA for these high and medium priority basins must then develop a Groundwater Sustainability Plan (GSP) that details how sustainable groundwater management will be achieved within 20 years of implementing the GSP. Sustainable groundwater management is defined by The Sustainable Groundwater Management Act as the management and use of groundwater in a manner that can be maintained during the planning and implementation horizon without causing undesirable results. This avoidance of undesirable results is measured through six sustainability indicators:

1. Chronic lowering of groundwater levels indicating a significant and unreasonable depletion of supply if continued over the planning and implementation horizon,

2. Significant and unreasonable reduction of groundwater storage,

3. Significant and unreasonable seawater intrusion,

4. Significant and unreasonable degradation of water quality,

5. Significant and unreasonable land subsidence, and

6. Depletion of interconnected surface water and groundwater that has significant and unreasonable adverse impacts on beneficial uses of the surface water.

The GSP is a tool used to help the GSA sustainably manage the basin. The criteria for sustainable management, including determining what is significant and unreasonable within the parameters of The Sustainable Groundwater Management Act for the Redlands Regular Meeting of 01-18-2022 Page 726 of 1274 Public Outreach and Engagement Plan
2 July 2019
groundwater basin managed by that GSA, must be assessed, with input from stakeholders, before the GSP can be adopted.

1.1 Sustainable Groundwater Management Act Requirements for Stakeholder Engagement
Stakeholder engagement is an important component of any successful long term planning effort. Engaging members of the public in groundwater sustainability planning will improve public understanding of the technical and political considerations the GSA factors into their decision-making process. Participation by the public will also improve the GSA’s understanding of the potential impacts of their decisions.

The Sustainable Groundwater Management Act recognized the importance of stakeholder engagement and laid out specific requirements for stakeholder engagement within each of the four phases of The Sustainable Groundwater Management Act:

Phase 1: GSA Formation and Coordination
The following Phase 1 requirements were completed by Yucaipa SGMA in 2017 and 2018:
 Establish and maintain a list of interested parties
 Provide public notice of the GSA formation
 Conduct a GSA formation public hearing
 Notify DWR of the GSA formation
 Provide a written statement to DWR as well as cities and counties within the GSA boundary describing how interested parties may participate in the GSP development.
 Develop GSA website for interested parties
Phase 2: GSP Preparation and Submission
The following Phase 2 requirements will be completed by Yucaipa SGMA by January 31, 2022:
 Submit initial notification.
 Prepare a GSP that considers beneficial uses and users of groundwater when describing undesirable results, minimum thresholds, projects and actions.  The GSP must include a communication section that includes the following:
o An explanation of the Agency’s decision-making process. o Identification of opportunities for public engagement and a discussion of how public input and response will be used.

Redlands Regular Meeting of 01-18-2022 Page 727 of 1274 Public Outreach and Engagement Plan
3 July 2019
o A description of how the Agency encourages the active involvement of diverse social, cultural, and economic elements of the population within the basin.
o The method the Agency will follow to inform the public about progress implementing the Plan, including the status of projects and actions.  The GSA must provide public noticing and hold a public meeting before adopting or amending a GSP.

Phase 3: GSP Review and Evaluation
The following Phase 3 requirements will be completed by DWR:
 After the GSA adopts the GSP and it is submitted to DWR, the GSP will be available on the DWR website for a 60-day comment period for any person to provide comments to DWR before the DWR completes evaluation and assessment of the GSP.

Phase 4: Implementation and Reporting
The following Phase 4 requirements will be completed by Yucaipa SGMA through 2042:
 The Sustainable Groundwater Management Act requires assessments and reevaluation of the GSP at least every 5 years. The GSA must provide public notice and hold public meetings prior to amending the GSP.
 Public notice is also required before the GSA imposes or increases fees.

There are also has general requirements that apply to all four phases of Sustainable Groundwater Management Act implementation.
2 YUCAIPA SUBBASIN AND GSA FORMATION
The Upper Santa Ana Valley Groundwater Basin, Yucaipa Subbasin lies under portions of the cities of Calimesa, Redlands, and Yucaipa, as well as unincorporated San Bernardino and Riverside Counties. The Subbasin, cataloged by the California Department of Water Resources (DWR) as groundwater basin number 8-2.07, is approximately 25,300 acres (Figure 1).

The Yucaipa Sustainable Groundwater Management Agency (Yucaipa SGMA) was formed as the GSA for the Yucaipa Subbasin in 2017 through a Memorandum of Agreement (MOA) entered into by local water purveyors, municipalities, and regional water management entities.

The Yucaipa SGMA completed the initial phase of stakeholder engagement (Phase 1) in June 2017 and provided the required documentation for GSA formation, which is available to the public through the DWR Sustainable Groundwater Management Act Portal (https://sgma.water.ca.gov/portal/gsa/print/349).

The City of Calimesa submitted a written Notice of Withdrawal dated November 19, 2018 and the Yucaipa SGMA subsequently acknowledged the withdrawal of the City of Calimesa from the Yucaipa SGMA at the January 23, 2019 meeting.

2.1 Yucaipa SGMA and GSA Decision Making Process
The roles and responsibilities of the Yucaipa SGMA were further clarified in the By-Laws adopted in May 2018. Each of the Member Agencies appoints one principal representative and one alternate representative to the Yucaipa SGMA Board. All Board meetings are public meetings subject to the Ralph M. Brown Act. Each Board member has one vote and a simple majority of 51% of the voting parties is required to pass an item. A majority of the Board is considered a quorum for purposes of meeting and decision-making.

3 YUCAIPA SUBBASIN GSP
The DWR has designated the Yucaipa Subbasin as a high-priority basin based on population size and growth, reliance on groundwater for public water supply, and longterm declines in groundwater levels. The Yucaipa Subbasin is not designated as critically overdrafted, therefore a GSP must be developed by January 31, 2022. This GSP will detail a pathway to sustainable groundwater management by 2042 in accordance with the Sustainable Groundwater Management Act.

Yucaipa SGMA has initiated the process of developing a GSP (Yucaipa GSP) for the Yucaipa Subbasin that will define a course of action to achieve sustainable groundwater management within 20 years of plan adoption. The Yucaipa GSP will identify local undesirable results and identify management actions to minimize undesirable results as well as milestones to ensure progress. A groundwater monitoring program will be developed and implemented to track improvement within the basins leading to sustainable management. The Yucaipa GSP will be re-evaluated and refined, as needed, and submitted to DWR every five years in accordance with the Sustainable Groundwater Management Act.
4 PURPOSE OF THE DOCUMENT
This Public Outreach and Engagement Plan (Plan) has been developed as a communication tool to help stakeholders understand the importance of participation in groundwater sustainability planning and lay the framework of how stakeholders can actively engage in the Yucaipa-GSA planning effort. In 2018, DWR released a guidance document for GSP Stakeholder Communication and Engagement that details best practices including the development of Communication and Engagement Plans to increase transparency in the GSP development process.

The Yucaipa SGMA will prepare a GSP in accordance with The Sustainable Groundwater Management Act that will guide future management decisions including the amount of ground water that can be pumped from the subbasin without causing undesirable results, and the development of new projects to enhance water resource management.

The Yucaipa SGMA discussed overarching goals for outreach and engagement at the April 24, 2019 Board Meeting. The primary goals during the GSP development process included:

1. Maintaining transparency throughout the GSP development process,

2. Developing a common understanding among stakeholders of the Yucaipa subbasin needs, and

3. Exceeding the state requirements for outreach and engagement.

This Plan is intended to be a guiding framework that will be updated as needed to maintain transparency throughout the GSP development and implementation process. 5 OPPORTUNITIES FOR PUBLIC INVOLVEMENT

AND ENGAGEMENT
The Yucaipa SGMA encourages members of the public to participate in the GSP development and implementation process through attending public meetings, providing comments on the draft GSP, and communicating directly with member agency staff and Board members.

During the development of the GSP, the Technical Advisory Group (TAG) will meet approximately monthly as needed. All Board and TAG meetings are open to the public and each meeting agenda includes an item where members of the public can speak to the Board. All meeting agendas and minutes are posted on the Yucaipa SGMA website (https://yucaipasgma.org).

5.1.1 Public Notices
Board meetings and workshops are noticed in accordance with the Brown Act. In addition to publicly noticing meetings on the Yucaipa SGMA website, the Yucaipa SMGA maintains a list of interested parties and distributes electronic agenda information and newsletters via email.

Interested parties can subscribe to the list that receives email notifications through the “subscribe” link at the bottom of the website home page (https://yucaipasgma.org).

5.2 Collaborative Opportunities
The Yucaipa-SMGA has taken an inclusive approach to groundwater management, making space on the Board for each of the local entities with water supply, water management, and or land use responsibility in the Yucaipa Subbasin that wanted to participate in the GSA. The Board understands that each interested party has an established relationship with their local water supplier that should continue through the development and implementation of the GSP. Each Board member is appointed by the Redlands Regular Meeting of 01-18-2022 Page 731 of 1274 Public Outreach and Engagement Plan
