issued with the Board approved recommendations.

agricultural industry. FFCB issues discount notes and bonds.

• FHLB. The Federal Home Loan Bank provides credit and liquidity in the housing
• market. FHLB issues discount notes and bonds.
• FHLMC. Like FHLB, the Federal Home Loan Mortgage Corporation provides credit

and liquidity in the housing market. FHLMC, also called “Freddie Mac” issues discount notes, bonds and mortgage pass-through securities.

• FNMA. Like FHLB and Freddie Mac, the Federal National Mortgage Association

was established to provide credit and liquidity in the housing market. FNMA, also known as “Fannie Mae,” issues discount notes, bonds and mortgage pass- through securities.

• GNMA. The Government National Mortgage Association, known as “Ginnie Mae,”

issues mortgage pass-through securities, which are guaranteed by the full faith and credit of the US Government.

• PEFCO. The Private Export Funding Corporation assists exporters. Obligations of

PEFCO are not guaranteed by the full faith and credit of the US government.

• r by pools of revolving lines of credit.

Average Life. In mortgage-related investments, including CMOs, the average time to expected receipt of principal payments, weighted by the amount of principal expected. Banker’s Acceptance. A money market instrument created to facilitate international trade transactions. It is highly liquid and safe because the risk of the trade transaction is transferred to the bank which “accepts” the obligation to pay the investor.

market index, which reflects the mix of securities allowed under a specific investment policy.

• Bid. The price at which a buyer offers to buy a security.
• Broker. A broker brings buyers and sellers together for a transaction for which the broker

receives a commission. A broker does not sell securities from his own position.

• Callable. A callable security gives the issuer the option to call it from the investor prior to

its maturity. The main cause of a call is a decline in interest rates. If interest rates decline since an issuer issues securities, it will likely call its current securities and reissue them at a lower rate of interest. Callable securities have reinvestment risk

Commented [GL16]: We recommend omitting specific benchmark information from the investment policy so that it can be changed easily if the District financial position changes along with its investment strategy.

Commercial Paper. The short-term unsecured debt of corporations. Cost Yield. The annual income from an investment divided by the purchase cost. Because it does not give effect to premiums and discounts which may have been included in the purchase cost, it is an incomplete measure of return.

• Coupon. The rate of return at which interest is paid on a bond.

Credit Risk. The risk that principal and/or interest on an investment will not be paid in a timely manner due to changes in the condition of the issuer. Current Yield. The annual income from an investment divided by the current market

• Discount. The difference between the par value of a bond and the cost of the bond, when

the cost is below par. Some short-term securities, such as T-bills and banker’s acceptances, are known as discount securities.

• Diversification. Dividing investment funds among a variety of investments to avoid

excessive exposure to any one source of risk.

• Duration. The weighted average time to maturity of a bond where the weights are the

present values of the future cash flows. Duration measures the price sensitivity of a bond to changes in interest rates. (See modified duration). Federal Funds Rate. The rate of interest charged by banks for short-term loans to other

• Liquidity. The speed and ease with which an asset can be converted to cash.

Make Whole Call. A type of call provision on a bond that allows the issuer to pay off the remaining debt early. Unlike a call option, with a make whole call provision, the issuer makes a lump sum payment that equals the net present value (NPV) of future coupon payments that will not be paid because of the call. With this type of call, an investor is compensated, or "made whole."

• Margin. The difference between the market value of a security and the loan a broker

makes using that security as collateral. Market Risk. The risk that the value of securities will fluctuate with changes in overall market conditions or interest rates. Market Value.

• Maturity. The final date upon which the principal of a security becomes due and payable.

Medium Term Notes. Unsecured, investment-grade senior debt securities of major corporations which are sold in relatively small amounts on either a continuous or an intermittent basis. MTNs are highly flexible debt instruments that can be structured to respond to market opportunities or to investor preferences. Modified Duration. The percent change in price for a 100 basis point change in yields. Modified duration is the best single measure of a portfolio’s or security’s exposure to market risk. Money Market. The market in which short-term debt instruments (T-bills, discount notes, commercial paper, and banker’s acceptances) are issued and traded. Mortgage Pass-Through Securities.

Mutual funds can be invested in various types of domestic and/or international stocks, bonds, and money market instruments, as set forth in the individual fund’s prospectus. For most large, institutional investors, the costs associated with investing in mutual funds are higher than the investor can obtain through an individually managed portfolio. Nationally Recognized Statistical Rating Organization (NRSRO). A credit rating agency that the Securities and Exchange Commission in the United States uses for regulatory purposes. Credit rating agencies provide assessments of an investment’s risk. The issuers of investments, especially debt securities, pay credit rating agencies to provide them with ratings.

Prudent Person (Prudent Investor) Rule. A standard of responsibility which applies to

• fiduciaries. In California, the rule is stated as “Investments shall be managed with

the care, skill, prudence and diligence, under the circumstances then prevailing, that a prudent person, acting in a like capacity and familiar with such matters, would use in the conduct of an enterprise of like character and with like aims to accomplish similar purposes.” Realized Yield. The change in value of the portfolio due to interest received and interest earned and realized gains and losses. It does not give effect to changes in market value on securities, which have not been sold from the portfolio. Regional Dealer. A financial intermediary that buys and sells securities for the benefit of its customers without maintaining substantial inventories of securities and that is not a primary dealer. Repurchase Agreement. Short-term purchases of securities with a simultaneous agreement to sell the securities back at a higher price. From the seller’s point of view, the same transaction is a reverse repurchase agreement.

• Safekeeping. A service to bank customers whereby securities are held by the bank in

the customer’s name. Structured Note. A complex, fixed income instrument, which pays interest, based on a formula tied to other interest rates, commodities or indices. Examples include inverse floating rate notes which have coupons that increase when other interest rates are falling, and which fall when other interest rates are rising, and "dual index floaters," which pay interest based on the relationship between two other interest rates - for example, the yield on the ten-year Treasury note minus the Libor rate. Issuers of such notes lock in a reduced cost of borrowing by purchasing interest rate swap agreements. Total Rate of Return. A measure of a portfolio’s performance over time. It is the internal rate of return, which equates the beginning value of the portfolio with the ending value; it includes interest earnings, realized and unrealized gains, and losses in the portfolio. U.S. Treasury Obligations. Securities issued by the U.S. Treasury and backed by the full faith and credit of the United States.

All securities issued with initial maturities greater than ten years are called Treasury bonds. Like Treasury notes, they pay interest semi-annually.

• Volatility. The rate at which security prices change with changes in general economic

conditions or the general level of interest rates. Yield to Maturity. The annualized internal rate of return on an investment which equates the expected cash flows from the investment to its cost.

For Action Fiscal Impact Funds Budgeted Information Only Cost Estimate: $ Background: TVMWD’s policy requires employees to contribute 10% towards their individual medical premiums, with the following exceptions:

• Employees hired before 12/31/10 under the previous allowance method
• Single employees enrolled in Kaiser (JPIA requires 100% to be paid by TVMWD)
• Employees enrolled in Anthem Blue Cross CDHP (Consumer Driven Health Plan)
• For employees enrolled in the CDHP, TVMWD contributes to an employee’s

HSA (Health Savings Account) plan (single - $400; two-party or more - $800). Employees may opt themselves and/or family members out of medical coverage with proof of comparable alternative medical coverage. The employee receives cash in the amount of 75% of the savings to TVMWD. JPIA requires that no more than 25% of TVMWD employees may opt out of medical coverage, so the opt out is on a first-come first-serve basis. For CY 2017, employees were only allowed to opt out if they had opted

For Action Fiscal Impact Funds Budgeted Information Only Cost Estimate: $ Discussion: Over the past several years, Six Basins Watermaster (6BWM) has been developing a Strategic Plan that basin stakeholders can use to help chart out future projects and

• programs. The Strategic Plan is now at a stage wherein projects previously identified by

the stakeholders can be presented for potential implementation. The 6BWM Board has determined that it would be beneficial to move the Strategic Plan forward with the evaluation of a set of identified projects. As part of this process, an environmental review that complies with the California Environmental Quality Act (CEQA) must be conducted. Through the CEQA process, a public agency must act as the lead agency to offer public review and evaluation of relevant data, receive and address comments associated with the environmental assessment, and to adopt appropriate findings associated with that

• review. Since 6BWM is not a public agency, but rather an arm of the court, its Board of

Directors have requested that Three Valleys MWD serve as the lead agency for the CEQA proceedings associated with the Six Basins Watermaster Strategic Plan. The 6BWM administrative staff has recommended that a Programmatic Environmental Impact Report (PEIR) be the avenue that the CEQA process followed in this case. If the TVMWD Board agrees that Three Valleys will serve as the lead agency, TVMWD staff will begin coordinating with 6BWM administrative staff to undertake the necessary activities for future review, notifications, advertisements, etc. It is anticipated that 6BWM administrative staff will continue to do the bulk of the work associated with this CEQA process, and TVMWD staff will assume some of the resulting administrative and clerical tasks along the way. Any costs incurred by Three Valleys will be reimbursed by 6BWM.

For Action Fiscal Impact Funds Budgeted Information Only Cost Estimate: $ Discussion: A brief status report for the Grand Avenue Well Project is provided below: TVMWD Grand Avenue Well Project – Project No. 58446 Staff has continued to discuss and coordinate the proposed well project with the city of Claremont, LDS Church, Caltrans, LA County Fire Department, and the state’s Division of Drinking Water. TVMWD also reached out to the nearby residents by scheduling a project informational meeting in June 2017. Staff responded to phone calls received from residents and were able to adequately address their questions. No residents showed up to the informational meeting. The District’s consultant has prepared the environmental (CEQA) documentation for this project which includes the initial study and mitigated negative declaration (IS & MND) that was recently completed in mid-August. The IS/MND will be posted and distributed on September 7, 2017 to begin the 30-day public review and comment period which will end

• n October 9, 2017. The environmental consultant and staff will prepare written

responses to public comments received. The public comments and responses will become part of the CEQA documents which will be brought before the Board for consideration and potential adoption on November 15, 2017 following the scheduled Public Hearing, which will be conducted as part of the Board Meeting. TVMWD’s engineering consultant completed the Preliminary Design Report (PDR) for the Grand Avenue Well in mid July. The engineering consultant will complete the final design for well drilling (phase 1) after board adoption of the CEQA documentation. Strategic Plan Objectives:

To: Six Basins Watermaster Board From: Wildermuth Environmental, Watermaster Staff Date: July 26, 2017 Subject: Evaluation of the Potential for Substantial Injury associated with the Proposed Grand Avenue Well  For Action  Fiscal Impact  Funds Budgeted  Information Only  Cost Estimate: $

Background and Previously Related Actions by the Board

Pursuant to Section III.B.4.b of the Six Basins Judgment, any Party that intends to acquire, construct or

• perate a new well in the Four Basins must provide a 30‐day advance written notice to the
• Watermaster. And, pursuant to Section III.B.4.a, groundwater production from a new location shall

not cause Substantial Injury to another Party. The Watermaster Board has drafted a proposed update to its Operating Plan describing a procedure to analyze certain “Actions” for the potential to cause Substantial Injury. The objective of the procedure is to establish a standard process to decide whether an Action should be evaluated for the potential to cause Substantial Injury, and if so, to conduct the evaluation. The proposed procedure is attached to this memo.1 Substantial Injury is defined in the draft Operating Plan update as: …injury to a Party, the basin, or the environment that is attributable to the implementation of an Action, including, but not limited to, rising groundwater, liquefaction, interference with the ability to pump OSY, increases in pump lift, degradation of water quality, or land subsidence. On May 24, 2016, Three Valleys Municipal Water District (TVMWD) notified Watermaster staff of its intent to drill, construct, develop, and operate a new well: TVMWD‐3. The Watermaster Board approved a Task Order for Watermaster Staff to perform an evaluation of the potential for Substantial Injury (Substantial Injury analysis) on TVMWD‐3 as a “test case” for the proposed process to inform the Watermaster of the potential for Substantial Injury. The objectives of this “test case” were to: (i) demonstrate the proposed process for evaluating projects and (ii) describe the potential impacts from the operation of TVMWD‐3 and potential mitigation measures, if deemed appropriate. The analysis

1 All memos developed in support of the update to the Operating Plan and the test case are available on Watermaster’s

website at: http://www.6bwm.com/info.php?pnum=6 under the header “Proposed Operating Plan Updates to Support Strategic Plan Implementation”

could then be used by the individual Parties to determine if the project impacts are potentially “Substantial” or not and to recommend mitigation measures, if necessary. The “test case” was a successful demonstration of the proposed process for evaluating projects for the potential to cause Substantial Injury. The evaluation described the potential impacts from the

• peration of TVMWD‐3, as well as measures that can be implemented to mitigate those impacts. The

main conclusions and recommendations of this “test” evaluation were documented in the August 24, 2016 memo Analysis for Substantial Injury for the Proposed TVMWD‐3 Well2, and included:  The new groundwater production planned by TVMWD from TVMWD‐3, which is about 600 acre‐feet per year (afy), will cause lower groundwater levels in the Six Basins, particularly in the Upper Claremont Heights Basin (UCHB) in the areas around TVMWD‐3.  The new groundwater production at TVMWD‐3 will not cause groundwater levels to decline below a sustainability metric at any Party’s well. That said, lower groundwater levels at wells, particularly north of the Indian Hill Fault, can lead to decreased well capacities, particularly during dry periods when groundwater levels are low.  Satisfying a Replacement Water obligation through wet‐water recharge for overproduction that occurs north of the Indian Hill Fault is an effective strategy to mitigate for lower groundwater levels, particularly if the recharge occurs near the areas of the new production.  During wet periods, the new production at TVMWD‐3 can help to mitigate instances of high groundwater (i.e. rising groundwater and liquefaction potential).  The conclusions above apply not only to TVMWD‐3, but to any new wells that are installed north of the Indian Hill Fault for the purpose of producing groundwater in volumes higher than historical volumes. Hence, future evaluations of Substantial Injury for proposed new wells located north of the Indian Hill Fault can leverage the information derived in this analysis and may not necessitate the use of the groundwater model in those evaluations. That said, additional new wells and groundwater production will have a cumulative impact on groundwater levels.

On June 5, 2017, TVMWD submitted a notification to Watermaster of its intent to drill, construct, develop and operate an additional new well in the UCHB: the Grand Avenue Well. The proposed location of the Grand Avenue Well is within the City of Claremont on a property located at the southern end of the cul‐de‐sac on North Grand Avenue south of Baseline Road. Figure 1 is a map that shows the proposed location of the well and nearby active production wells. The nearest active production wells are the Golden State Water Company’s (GSWC) Mills 1, Mountain View 1, and Marlboro wells, all of which are located within 1,800 feet of the proposed Grand Avenue Well.

TVMWD currently plans the following for the construction and operation of the Grand Avenue Well: Casing depth: 880 ft‐bgs Casing diameter: 16 inches Well‐screen depth interval: 300‐800 ft‐bgs Pumping rate: 600‐800 gallons per minute Estimated annual production: 775‐1,030 afy Well utilization: 80‐85 percent of the time Well use: Supplement imported water supplies from the Miramar Treatment Plant Water rights: TVMWD is an overproducer of its Operating Safe Yield (OSY) rights, so production from the Grand Avenue Well will incur a Replacement Water obligation. TVMWD’s preferred method for Replacement is to maximize transfers of unproduced OSY rights from other Parties and then utilize its Storage and Recovery account to make up the difference. On June 28, 2017, Watermaster Staff advised the Board that the operation of the Grand Avenue Well should be evaluated for the potential to cause Substantial Injury and the evaluation could be performed based on the results of the Analysis for Substantial Injury for the Proposed TVMWD‐3 Well. The Board directed Watermaster Staff to perform a Substantial Injury analysis on TVMWD’s Grand Avenue Well. This Substantial Injury analysis also considers the cumulative impacts of the TVMWD‐3 and Grand Avenue wells.

Methods to Evaluate the Potential for Substantial Injury

The method to evaluate the impacts from operating the Grand Avenue Well is to utilize the results of the Substantial Injury analysis performed for TVMWD‐3. The method that was used to evaluate the impacts of TVMWD‐3 included:

• 1. Development of a “Baseline” planning alternative that does not include the operation of

TVMWD‐3.

• 2. Development of two project alternatives that included the operation of TVMWD‐3 at a range
• f annual production rates of 450 afy in dry years and 685 afy in wet years, and replacement
• perations from most impactful to least impactful:
• a. TVMWD Preferred Alternative: TVMWD satisfies its Replacement Water obligation for

production from TVMWD‐3 through increased transfers (assumed to be up to 10 percent of the OSY) and use of its Storage and Recovery account.

• b. Replacement Alternative: TVMWD satisfies its Replacement Water obligation for

production from TVMWD‐3 through wet‐water recharge at the San Antonio Spreading Grounds (SASG). The wet‐water recharge is equal to the annual production of TVMWD‐3. Item 08 Page 78 of 107

Item 8.C.2

• 3. Use of the Six Basins groundwater‐flow model to simulate the hydrologic response of all three

planning alternatives over a long‐term (54‐year) hydrologic period3, and compare and contrast the model‐simulation results. The impacts evaluated included: changes in groundwater levels; production sustainability at wells; the threat of high groundwater; and the water budget of the Six Basins. This evaluation of the operation of the proposed Grand Avenue Well is a qualitative analysis that references the model results from the analysis of TVMWD‐3 and discusses potential changes in groundwater levels and water budget; production sustainability at wells; and the threat of rising groundwater.

Evaluation of the Potential for Substantial Injury

Table 1a summarizes the average and total planning period production, transfers, storage extractions and wet‐water recharge associated with the operation of the Grand Avenue Well for the three planning alternatives assuming no production from TVMWD‐3. Table 1b summarizes the same information for the three alternatives assuming production from both the TVMWD‐3 and the Grand Avenue wells. Over the 54‐year planning period, the proposed operation of the Grand Avenue Well will result in a total increase in production of about 52,000 af, or about 970 afy. If operated together with the TVMWD‐3 well, the total increase in production over the Baseline is about 87,400 af, or about 1,600 afy. TVMWD Preferred Alternative Over the 54‐year planning period, the proposed operation of the Grand Avenue Well under the TVMWD Preferred Alternative, as compared to the Baseline, will result in the following:  A total increase in transfers from other Parties to TVMWD of about 34,600 af, or about 640

• afy. If operated together with the TVMWD‐3 Well, the total increase in transfers is about

34,800 af, or about 650 afy.  A total increase in extractions from the TVMWD storage account of about 17,440 af, or about 320 afy. If operated together with the TVMWD‐3 Well, the total increase in extractions from the TVMWD storage account is about 46,920 af, or about 870 afy.  No increase in wet‐water recharge for Replacement Water obligations due to the proposed

• peration of the Grand Avenue Well. If operated together with the TVMWD‐3 Well, the total

increase in wet‐water recharge for Replacement Water obligations is about 4,000 af, or about 70 afy.  A total increase in wet‐water recharge to build the TVMWD storage account of about 18,540 af, or about 340 afy. If operated together with the TVMWD‐3 Well, the total increase in wet‐ water recharge to build TVMWD storage account is about 48,800 af, or about 900 afy.

3 The planning period, defined as July 20133 to June 2066, includes a variable hydrology based on the historical record of

precipitation for the period of 1960 to 2013 and current land use.

Figure 2 shows the difference in groundwater levels between the TVMWD Preferred Alternative and the Baseline Alternative at the end of the driest period within the 54‐year model simulation from the Analysis for Substantial Injury for the Proposed TVMWD‐3 Well. In this alternative, groundwater levels are projected to be lower across the Six Basins, compared to the Baseline, because groundwater production is about 600 afy higher on average, and artificial recharge of imported water is only about 70 afy higher. Groundwater levels are projected to decline by as much as 20 feet around TVMWD‐3, where the new production occurs. The groundwater‐level declines do not cause water levels to drop below the sustainability thresholds of any Party’s wells in the Six Basins. During wet periods, the projected lower groundwater levels are beneficial because they reduce the amount of time that groundwater levels are within 40 feet of the ground surface, which is the threshold for liquefaction

• potential. Regarding the water budget, the projected lower groundwater levels will reduce subsurface
• utflow to the Two Basins and to the Chino Basin. This results in an increase to the overall developed

yield of the Four Basins by about three percent relative to the Baseline, and decreases the developed yield of the Two Basins by about two percent. The Grand Avenue Well is proposed to produce between 775 and 1,030 afy, which more than the 450 to 685 afy planned and evaluated for TVMWD‐3. Therefore, under the TVMWD preferred operation

• f the Grand Avenue Well, there is likely to be similar or greater magnitudes of groundwater‐level

declines surrounding the Grand Avenue Well and reduction of outflow to the Chino Basin and Two Basins as was predicted for the TVMWD‐3 well. If both wells are in operation at the same time, there will be cumulative effects of changes to groundwater levels and subsurface outflow that are greater than the effects of the wells individually. For example, Figure 2 shows that the groundwater levels at the Grand Avenue Well site are predicted to be about eight feet lower compared to the Baseline due to the operation of the TVMWD‐3 well. If about 20 feet of groundwater‐level decline is predicted to

• ccur at the Grand Avenue Well site as a result of operating the Grand Avenue Well, groundwater

levels at the Grand Avenue Well site could be about 28 feet lower compared to the Baseline. The potential impacts of the lower groundwater levels at other wells, particularly for those wells located within the UCHB in areas between the TVMWD‐3 and Grand Avenue wells, include: (1) lower production capacities, (2) greater pumping lifts, and (3) increased cost due to the greater pumping

• lifts. The wells that are likely to experience the greatest cumulative effects under this alternative

include:  Indian Hills 3 (GSWC)  Indian Hills 4 (GSWC)  Marlboro (GSWC)  Mountain View 1 (GSWC)  Mills 1 (GSWC)  Tunnel Well 1 (City of Pomona)  Tunnel Well 2 (City of Pomona)  Tunnel Well 3 (City of Pomona)  Tunnel Well 4 (City of Pomona) Figures B‐3 to B‐5 and B‐6 to B‐11 are time‐history charts of projected groundwater elevations from the Analysis for Substantial Injury for the Proposed TVMWD‐3 Well. These charts show that the groundwater elevations at these wells under the TVMWD Preferred Alternative are up to about 13 to 16 feet lower compared to the Baseline. Therefore, the cumulative groundwater‐level declines from production at both the TVMWD‐3 and Grand Avenue wells are expected to be greater than 13 to 16 Item 08 Page 80 of 107

Item 8.C.2

Page 6 of 7

feet at these wells. These charts show that it is unlikely that the production of the proposed Grand Avenue Well, combined with the production at the proposed TVMWD‐3 Well, will cause water levels to decline below the sustainability thresholds of any Party’s wells in the Six Basins. For example, Figure B‐5 shows the projected lowest groundwater level at Mills‐1 is about 15 feet above its sustainability threshold; if the groundwater‐level decline at Mills‐1 were to double due to the production at the Grand Avenue Well, the lowest water level at Mills‐1 would be about nine feet above its sustainability threshold. Replacement Alternative Over the 54‐year planning period, the proposed operation of the Grand Avenue Well under the Replacement Alternative, as compared to the Baseline, will result in the following:  No increase in transfers from other Parties to the TVMWD to offset Replacement Water

• bligations.

 No increase in extractions from the TVMWD storage account to offset Replacement Water

• bligations.

 A total increase in wet‐water recharge for Replacement Water obligations of about 52,020 af,

• r about 960 afy. If operated together with the TVMWD‐3 Well, the total increase in wet‐water

recharge for Replacement Water obligations compared to the Baseline is about 85,750 af, or about 1,590 afy.  No increase in wet‐water recharge to build the TVMWD storage account. Figure 3 shows the difference in groundwater levels between the Replacement Alternative and the Baseline Alternative at the end of the driest period within the 54‐year model simulation from the Analysis for Substantial Injury for the Proposed TVMWD‐3 Well. In this alternative, groundwater levels are projected to be up to seven feet lower around TVMWD‐3 (where the new production occurs) compared to the Baseline. Groundwater levels are projected to be up to six feet higher compared to the Baseline in the southern portion of the SASG where the Replacement Water was assumed to be

• recharged. Regarding the water budget, the replacement will in part mitigate the reduction in

subsurface outflow to the Two Basins, but will result in an increase in subsurface outflow to the Chino Basin. Under the operating scheme of the Replacement Alternative, the cumulative effects on groundwater levels associated with pumping both TVMWD‐3 and Grand Avenue wells will be mitigated by the greater volumes of recharge at the SASG that will be required to satisfy the TVMWD Replacement Water obligations. The declines in groundwater levels west of the Grand Avenue Well will be greater than the declines predicted in the Replacement Alternative for TVMWD‐3, and the increases in groundwater levels in the vicinity of the southern SASG (where the recharge is assumed to occur) and

• utflow to Chino Basin are expected to be greater than predicted in the Replacement Alternative for

TVMWD‐3. Item 08 Page 81 of 107

Conclusions and Recommendations

The main conclusions and recommendations of this evaluation of the potential for Substantial Injury associated with the Grand Avenue Well are similar to those stated in Analysis for Substantial Injury for the Proposed TVMWD‐3 Well:  Groundwater levels will be lower across the Six Basins, particularly if both the TVMWD‐3 and the Grand Avenue wells are operated at the same time and TVMWD chooses to utilize transfers and extractions from its Storage and Recovery account as the methods to satisfy its associated Replacement Water obligations. The declines in groundwater levels are predicted to be greatest during dry periods within the UCHB in areas nearby and in‐between the two new wells.  If both the TVMWD‐3 and Grand Avenue wells are operated at the same time, the predicted declines in groundwater levels are unlikely to cause water levels to decline below sustainability thresholds at other Party’s wells, but can lead to decreased well capacities and increased pumping lifts, particularly during dry periods when groundwater levels are low.  The predicted lower groundwater levels will have the beneficial effects of mitigating instances

• f high groundwater during wet periods (i.e. mitigation for rising groundwater and liquefaction

potential).  Satisfying Replacement Water obligations through wet‐water recharge for overproduction that occurs north of the Indian Hill Fault is an effective strategy to mitigate for lower groundwater levels during dry periods, particularly if the recharge occurs near the areas of the new production. During wet periods, wet‐water recharge to satisfy Replacement Water

• bligations could increase the potential for high groundwater conditions and increase

subsurface outflow to the Chino Basin. Thus, an operational strategy that combines aspects of the TVMWD Preferred Alternative during periods wet periods and the Replacement Alternative during dry periods could minimize the potential for Substantial Injury associated with the operation of the Grand Avenue and/or TVMWD‐3 wells.

Evaluation for the Potential for Substantial Injury Definitions:

Action means

 installing a new production facility,  re‐location of a production facility,  constructing and operating a new recharge project,  a new or revised storage and recovery agreement,  transfers of production rights,  a Special Project, as defined in Section VI.B.11 of the Judgment, or  a combination of the any of the above,

Application means a written notice of a proposed Action or written request for Watermaster approval of a proposed Action submitted by any Party. Applicant means a Party that submits an Application, as defined in the prior section, to Watermaster. Substantial Injury means injury to a Party, the basin, or the environment that is attributable to the implementation of an Action, including, but not limited to, rising groundwater, liquefaction, interference with the ability to pump OSY, increases in pump lift, degradation of water quality, or land subsidence. Actions are evaluated on a case‐by‐case basis to determine whether they have the potential to cause Substantial Injury.

Process to Evaluate for the Potential for Substantial Injury:

Staff is currently reviewing the 95% design to provide comments that will allow the consultant to complete the final design. Staff anticipates the final design will be completed in late September at which point staff will obtain informal quotes for construction from several contractors. Carports Useful Life Structural Review As part of its continuing assessment of the Miramar infrastructure, staff has reviewed and evaluated the existing onsite carports and have found them to be at the end of their useful life. There is observable evidence of wooden structural beams bowing and cracking, degraded fascia, decking, and asphalt roofing. In an effort to delay capital expenditures, spot repairs have been made in the past few years including sections

• boards. The structures have also

been painted in the past to improve their aesthetic appearance, but this did little to

improve the overall physical structure. These repairs helped to delay the inevitable aging and structural deterioration. For these reasons, staff proposes replacement of existing carports and installation of new carports in portions of existing open parking spaces. A design for new and replacement structural carports are in the process of being

• completed. The replacement carports will be a cantilever design with steel HSS tubing

and metal roof deck, modernizing its form and function, and providing a minimum 50-year useful life. This all steel cantilever design will also provide a cleaner appearance with a single row of columns set “inside” the carports. Staff has made the carport design flexible to be able to accept photovoltaic (PV) panels atop the roof deck in the future. Cost and contractual restrictions with Edison do not make it favorable at this time to add PV panels. If conditions change in the future, staff will re- evaluate the benefits of developing solar energy for the Miramar site.
