UPDATE ON CAL AM ITEMS Th8a & 9a
(as of November 6, 2019)

The Coastal Commission will be holding a public hearing on the proposed Cal-Am water project on Thursday, November 14, 2019, but it will not take a final vote to approve or deny the project. Instead, this item will be continued to a later date. The reason for the change is that Coastal Commission staff met with CPUC staff to discuss the posted staff recommendation on the Cal-Am project. The CPUC staff raised a range of new technical questions regarding water supply and demand, potential ground water impacts, and the Pure Water expansion alternative – all of which require further investigation. The Coastal Commission staff believes that it is essential to hear applicant, agency, and public comments in a public hearing and to explore the key remaining technical questions before the Commission considers voting on the project proposal. The Commission will hold the public hearing in Half Moon Bay (Oceano Hotel & Spa, 280 Capistrano Road, Half Moon Bay), as planned and accept testimony at the Marina offsite location (City of Marina Council Chambers, 211 Hillcrest Ave., Marina), as planned, consistent with the posted hearing procedures. A second hearing will be scheduled, possibly in Scotts Valley in March 2020, where the public will again have ample opportunity to give testimony on the project before a final decision.
Thank you.

NOTEWORTHY EXCERPTS:

4. Why aren’t the Commissioners taking a final vote on this proposal?
It is not unusual for the Commissioners to need more than one hearing to make a final decision on items as complex as the Cal-Am desalination proposal. In this case, Coastal Commission staff met with California Public Utilities Commission (CPUC) staff to discuss the posted staff recommendation on the Cal-Am project. The CPUC staff raised new technical questions about water supply and demand, potential ground water impacts, and the Pure Water expansion alternative – all of which require further investigation. Commission staff therefore decided it was important to hear applicant, agency, and public comments in a public hearing and to explore key remaining technical questions before the Commission considers voting on the project proposal.

5. Will there be any voting on this item?
There will not be a Commission vote on whether to approve or deny the Cal-Am project at the November hearing. However, because item 8a is an appeal of a local permit decision, the Commission may vote on whether the appeal raises a “substantial issue.” If the Commission finds that it does, that will allow the hearing on the appeal to move forward. Then the Commission will open the public hearing and take public comment on whether to approve or deny Cal-Am’s project. The hearing will address all aspects of the project proposed in the coastal zone including the portion in the City of Marina that is on appeal (item 8a) and those portions in the County and Seaside and in the Commission’s own permitting jurisdiction (item 9a). The next hearing on this item will likely be scheduled for March in Santa Cruz.

Monterey Peninsula Water Management District
Preliminary Valuation and Cost of Service Analysis Report
October 29, 2019
Executive Summary
The purpose of this report is to document the findings of a preliminary valuation assessment and cost of service evaluation completed to support the Monterey Peninsula Water Management District (“MPWMD” or “District”) in evaluating the feasibility of securing and maintaining public ownership of the Monterey Water System. The preliminary valuation assessment consisted of completion of a preliminary desktop valuation assessment of the Monterey Water System to estimate the cost required to be incurred to acquire the Monterey Water System. The cost of service analysis was completed to compare the cost of public ownership, operation, and maintenance of the Monterey Water System (i.e. the public ownership scenario) with a status quo scenario, which is the anticipated cost of continued ownership, operation, and maintenance of the system by California American Water (“CAW”). The cost of service analysis was compared in terms of the annual Monterey Water System revenue requirements and typical residential customer bill impacts associated with the various scenarios that were developed.
CAW currently provides water service to approximately 41,000 customer connections and a population of approximately 99,794 in its Monterey County District. The “Main” system within the Monterey County District serves approximately 38,325 customers and includes customers within the incorporated cities of Carmel-by-the-Sea, Del Rey Oaks, Monterey, Pacific Grove, Sand City, Seaside, and the unincorporated areas of Carmel Highlands, Carmel Valley and Pebble Beach. The Main system is generally located within the MPWMD boundaries. The Monterey County District also includes the areas of Bishop, serving approximately 385 customers, Hidden Hills, serving approximately 454 customers, and Ryan Ranch, serving approximately 212 customers, which are areas that are also within the MPWMD boundaries.1 The Central Satellite areas include the areas of Ambler, Ralph Lane, Chualar, Toro, and Garrapata, which are located outside of MPWMD boundaries and serve a total of approximately 1,086 customers. The subject of the preliminary valuation and cost of service analysis is the portion of the water system located within the boundaries of the District.
Preliminary Valuation Assessment
The valuation of the Monterey Water System was prepared for acquisition feasibility purposes
considering three methods of valuation: the Income Approach, the Sales Comparison Approach, and the Cost Approach. The definition of value used in the valuation assessment was fair market value as the term is defined in California’s Eminent Domain Law (Code of Civil procedure Section 1263.320), and the date of the valuation estimate was January 1, 2020.
The income approach is based on the premise that the value of a property is the present value of the future economic benefits of owning the property. The underlying principle in this approach is that buyers invest in assets with the expectation of receiving the anticipated future net benefits. This approach is relevant when the property being valued generates or is anticipated to generate net income, profits, or free cash flows. The value estimate of the Monterey Water System calculated using the income approach ranged $222 million to $255 million. An 80% weighting was placed on the results of this valuation method.
The Market Approach is a general way of determining an indication of value of an enterprise by comparing the subject to similar businesses that have been sold. The valuation estimate under the market approach was prepared using the Guideline Transactions Method, which is a method whereby pricing multiples are derived from transactions involving companies engaged in the same or similar lines of business. Certain factors, such as the location, date of sale, physical characteristics, and technical and economic factors relating to sales transactions were analyzed for their comparability to CAW’s Monterey Water System. Based on this analysis, the average value of the Monterey Water System under the market approach was estimated to be approximately $272 million. A 20% weighting was placed on the results of this valuation method.
Under the Cost Approach, the value of the assets is typically derived by subtracting the amount of depreciation from the replacement or reproduction cost of the assets. The value under this approach is estimated by the sum of the parts of the system, i.e. physical asset components, land, water rights, etc. Depreciation in this context represents the loss in value caused by physical deterioration, functional obsolescence, and economic obsolescence. The reproduction cost new less depreciation (“RCNLD”) amount was calculated and estimated to be approximately $464 million. No weighting was placed on the results of this valuation approach because it tends to place an absolute ceiling on the market price, which most frequently is not approached in actual market negotiations associated with regulated public utilities.
Combining these three valuation methods with their weightings, the base estimated value of the Monterey Water System (portion located within MPWMD jurisdictional boundaries) as of the valuation date (January 1, 2020) was estimated to be approximately $245 million. This estimate is a preliminary estimate of value that was prepared based on a desktop analysis described above for feasibility purposes and information available as of the date of this report. This value estimate may be higher or lower than the conclusion of value that may result from the completion of a formal appraisal.
This base estimate excludes the value of asset additions, such as construction-work-in-progress, 30% of the Monterey Pipeline and Pump Station value deemed by the California Public Utilities Commission (“CPUC”) not to be “used and useful” in conjunction with CAW’s Monterey Water System, the value of the desalination plant currently under development, and the value of non “used and useful” land parcels. The value of the Monterey Water System, including the base value and the identified asset additions, was estimated to be approximately $359 million.
CAW has incurred other expenses that CPUC has approved for recovery through Monterey District water rates over time. It is possible that MPWMD may be required to compensate CAW for these unrecouped expenses as part of a potential taking of the Monterey Water System. These expense items and their potential amounts include unrecouped portions of tank painting expenses, San Clemente Dam removal costs, the portion of the “acquisition premium” allocable to the Monterey Water System that was approved by the CPUC in 2001 in connection with CAW’s acquisition of the California assets of Citizens Water Company, the portion of the “acquisition premiums” allocable to the Monterey Water System associated with the acquisition of the Bellflower Municipal Water System, the Rio Plaza Water Company, Fruitridge Vista Water Company, and Hillview Water Company that are proposed under CAW’s Special Request No. 11 in its 2019 General Rate Case Application to the CPUC, plus the unrecovered portions of various balancing accounts. These net expenses were estimated to total approximately $155 million as of the valuation date, and adding these net expenses to the value estimate of the “base” water system results in a total value estimate, plus adjustments, of approximately $513 million. A summary of the valuation and adjustments is provided in Table ES-1.
This value estimate, with adjustments, does not include the potential value of other assets that are not currently included in CAW’s rate base, except for the value of land which has been considered. These assets either have not been deemed to be “used and useful” for the provision of water service or were developer contributed and are not allowed by CPUC to be included in rate base. It is possible that some of the non “used and useful” assets may become “used and useful,” and recoverable in water rates in the future. However, the value of these assets is not likely to be substantial. CAW reports a value of $20.2 million of “contributions-in-aid-of construction” and “advances-in-aid-of-construction”, which are contributions of money or property contributed by developers pertaining to the expansion, improvement, or replacement of water system assets. However, since CAW is not allowed to include the value of these assets in rate base, they have been excluded from consideration in the value of the Monterey Water System.
MPWMD may also be required to pay severance damages to CAW for acquiring the Monterey Water System. These damages may relate to not taking the satellite water systems owned and operated by CAW within their Monterey District, but outside of MPWMD’s jurisdictional boundaries. Severance damages in this instance would consist of increased inefficiencies in CAW’s provision of service to these smaller pockets of customers and potentially higher costs per customer to do so. It is somewhat difficult to evaluate and quantify such severance damages, which would involve better understanding CAW’s current service model, how CAW could most effectively modify its service model in the post-District acquisition scenario, and how much of the work formerly performed by local CAW staff could effectively be transferred to other nearby CAW field offices or centralized locations. In addition, given that CAW would likely be entitled to include reasonable increased marginal operating costs in its next rate filing(s) to the CPUC with respect to the “remainder” of its Monterey District, it is questionable whether CAW would suffer any net profitability losses at all. Given these uncertainties, and the likelihood that CAW could mitigate some or all of its severance damages through the CPUC ratemaking process, our tentative conclusion is that CAW is likely to suffer minimal, if any, severance damages, and any severance damages it does suffer would not be so significant as to materially affect the conclusions of the District’s feasibility analysis. If the District does proceed to prepare a formal appraisal of just compensation for the acquisition of the Monterey Water system, however, it is recommended that the severance damages issue be further reviewed at that time.
Cost of Service Evaluation
The cost of service evaluation consisted of preparing a 20-year financial projection of CAW continuing to own and operate the Monterey Water System (status quo), analyzing and identifying the incremental cost differences associated with MPWMD owning and operating the Monterey Water System in comparison to the status quo, preparing an annual cash flow projection of two district ownership scenarios, and estimating customer bills under both the CAW status quo and District ownership scenarios. The following cost of service scenarios were prepared:
A. Status Quo – CAW ownership
B. MPWMD Ownership with District staff operations
C. MPWMD Ownership with contract operations
The cost of service modeling results indicate that significant annual reductions in revenue requirements Water System. The estimated revenue requirement in 2022 under the MPWMD ownership scenario with District operations (Scenario B) was projected to be approximately $13.6 million or 11.9% lower than the status quo CAW ownership scenario (Scenario A). Scenario B is estimated to have a net present value savings from 2021 to 2040 of approximately $267 million. The estimated revenue requirement in 2022 under MPWMD ownership and contract operations (Scenario C) was projected to be approximately $10.2 million or 8.9% lower than the status quo CAW ownership scenario (Scenario A). Scenario C is estimated to have a net present value of savings from 2021 to 2040 of approximately $213 million. These net present value savings estimates include the debt service costs associated with the District paying fair market value for CAW’s Monterey Water System. These cost of service modeling results are summarized in Table ES-2.
The projected reductions in revenue requirements are a result of the following differences between CAW and MPWMD ownership and operation:
1. Lower corporate and administrative overhead costs. An estimated $7.2 million in CAW corporate administrative overhead would be avoided under MPWMD and replaced with approximately $1.8 million in District operations and administrative costs.
2. Operating cost differences. The District’s ability to utilize existing administrative staff and eliminate redundant positions, net of higher pension and benefit costs under public ownership.
3. Cost of public financing (4.0% interest rate) vs. rate of return and CAW profit (7.61%). The tax exempt annual debt interest rate for MPMWD is lower than taxable corporate debt and CAW’s allowable rate of return. The public financing interest rate was reviewed by Barclays and was deemed to be reasonable.
4. Reduction in revenue requirements of an estimated $10.1 million per year (2021 estimate) under public ownership due to avoidance of property and income taxes.
5. Elimination of rate regulatory expenses estimated at $330,000 per year (2021 estimate).
Based on the information and estimates summarized in this report, which are reasonable considering the currently available information, the acquisition of the Monterey Water System by MPWMD appears to be economically feasible. Economic feasibility was assessed by comparing the estimated revenue requirements of the water system under MPWMD ownership versus CAW ownership and indicated that significant revenue requirement savings could be achieved under the MPWMD ownership scenarios that were evaluated
6. Findings and Conclusions
Set forth below is a summary of the findings and conclusions which Raftelis has reached regarding its preliminary valuation and cost of service feasibility study. For a complete understanding of the estimates and assumptions upon which these opinions are based, this report should be read in its entirety.
1. The base estimated value of the Monterey Water System (portion located within MPWMD
jurisdictional boundaries) as of the valuation date (January 1, 2020) is estimated to be approximately $245 million. This estimate is a preliminary estimate of value that was prepared based on a desktop analysis described above for feasibility purposes and information available as
of the date of this report. This value estimate may be higher or lower than the conclusion of
value that may result from the completion of a formal appraisal.
2. This base estimate excludes the value of asset additions, such as construction-work-in-progress, 30% of the Monterey Pipeline and Pump Station value deemed by CPUC not to be used and useful, the value of the desalination plant, and land estimated to be non “used and useful.” The potential value of these additional items was estimated separately and total approximately $114 million. In addition, it was assumed that MPWMD would assume the anticipated SRF loan and any public agency financing associated with the desalination plant (estimated at approximately $181 million), therefore, these amounts were excluded from the valuation estimate but were considered as part of the cost of service evaluation. The value of the Monterey Water System, including the base value estimate and the identified asset additions, was estimated to be approximately $359 million.
3. CAW has incurred other expenses that CPUC has approved for recovery through Monterey District over time. It is possible that MPWMD may be required to compensate CAW for these unrecouped expenses as part of a potential taking of the Monterey Water System. These expense items and their potential amounts include unrecouped portions of tank painting expenses, San Clemente Dam removal costs, the portion of the “acquisition premium” allocable to the Monterey Water System that was approved by the CPUC in 2001 in connection with CAW’s acquisition of the California assets of Citizens Water Company, the portion of the “acquisition premiums” allocable to the Monterey Water System associated with the acquisition of the Bellflower Municipal Water System, the Rio Plaza Water Company, Fruitridge Vista Water Company, and Hillview Water Company that are proposed under CAW’s Special Request No. 11 in its 2019 General Rate Case Application to the CPUC, plus the unrecovered portions of various balancing accounts. These net expenses were estimated to total approximately $155 million as of the valuation date, and adding these net expenses to the “base” water system value estimate, results in a total value estimate plus adjustments of approximately $513 million.
4. Non-Regulated Assets of CAW’s Monterey Water System. Other non-regulated assets of CAW’s Monterey Water System may include other assets that are not currently included in its rate base, except for the value of land which has been considered. These assets either have not been deemed to be “used and useful” for the provision of water service or were contributed by developers and are not allowed by CPUC to be included in rate base. It is possible that some of these non “used and useful” assets may become “used and useful” and could become recoverable in rate base in the future. However, the value of these assets is not likely to be substantial. CAW reports a value of $20.2 million of “contributions-in-aid-of-construction” and “advances-in-aid-ofconstruction.” However, since CAW is not allowed to include the value of these assets in rate base, they have been excluded from consideration in the value of the Monterey Water System.
5. Severance Damages. MPWMD may be required to pay severance damages to CAW for acquiring the Monterey Water System. These damages may relate to not taking the satellite water systems owned and operated by CAW within their Monterey District, but outside of MPWMD’s jurisdictional boundaries. California Code of Civil Procedures Section 1263.420 states that where the public entity is taking less than an entire piece of property, the possibility of severance damages to the remainder should be considered. These damages may relate to not taking the satellite water systems owned and operated by CAW within their Monterey District, but outside of MPWMD’s jurisdictional boundaries. Our tentative conclusion is that CAW is likely to suffer minimal, if any severance damages and any severance damages it does suffer would not be so significant as to materially affect the conclusions of the District’s feasibility analysis. If the District does proceed to prepare a formal appraisal of just compensation for the acquisition of the Monterey Water system, however, it is recommended that the severance damages issue be further reviewed at that time.
6. The cost of service modeling results indicate that significant annual reductions in revenue requirements and projected monthly water bills can be realized by MPWMD acquiring and operating the Monterey Water System. The estimated revenue requirement in 2022 under the MPWMD ownership scenario with District operations (Scenario B) was projected to be approximately $13.6 million or 11.9% lower than the status quo CAW ownership scenario (Scenario A). Scenario B is estimated to have a net present value savings from 2021 to 2040 of approximately $267 million. The estimated revenue requirement in 2022 under MPWMD ownership and contract operations (Scenario C) was projected to be approximately $10.2 million or 8.9% lower than the status quo CAW ownership scenario (Scenario A). Scenario C is estimated to have a net present value of savings from 2021 to 2040 of approximately $213 million. These net present value savings estimates include the debt service costs associated with the District paying fair market value for CAW’s Monterey Water System.
7. Based on the information and estimates summarized in this report, which are reasonable considering the currently available information, the acquisition of the Monterey Water System by MPWMD appears to be economically feasible. Economic feasibility was assessed by comparing the estimated revenue requirements of the water system under MPWMD ownership versus CAW ownership, which indicate significant revenue requirement savings could be achieved under the MPWMD ownership scenarios that were evaluated.

CALIFORNIA COASTAL COMMISSION: Independent Hydrogeological Review of Recent Data and Studies Related to California American Water’s Proposed Monterey Regional Water Supply Project Weiss Job No. 466-2148, November 1, 2019 (EXHIBIT 7) & Addendum

ABSTRACT:  EXHIBIT 7, the draft report, dated November 1, 2019, to Tom Luster, California Coastal Commission, from William A. McIlvride, PG, CEG, CHG, Senior Project Hydrogeologist, “documents Weiss Associates (Weiss’s) independent hydrogeological review of data and studies related to California American Water’s (Cal-Am) proposed Monterey Regional Water Supply Project (MRWSP).” Selected excerpts, as follows:
The specific study questions the Commission requested technical opinions from Weiss to address are:
1. What were the effects of potential and actual changes in hydraulic gradient since January 2017, and what is the potential for these changes to affect potential seawater intrusion to, and capture of fresh water from, aquifers tapped by the well field?
2. What is the potential for the well field to adversely affect or capture previously unidentified volumes of fresh water? and
3. What are the possible project modifications to avoid or reduce the potential effects?
SUMMARY OF FINDINGS
Weiss’s findings with respect to the Commission’s study questions are addressed in detail in this report and summarized as follows:
1. A steepening of the hydraulic gradient seaward in the Dune Sand Aquifer in 2017 will likely result in a limited to negligible effect on seawater intrusion, and likely result in an increase in the fresh water percentage (FWP) of the well field flow due to capture of fresh water from the aquifers tapped by the well field. The gradient change appears to result from local and regional aquifer recharge due to increased rainfall in the 2016-2017 and 2018-2019 rain years. This is significant to the evaluation of the FWP percentages resulting from the MRWSP since there are significant data gaps with respect to groundwater flow paths in the Dune Sand Aquifer and the transfer of fresh water (total dissolved solids [TDS] < 3,000 milligrams per liter [mg/L]) from the Sand Dune Aquifer to the 180-foot Aquifer. Therefore, to be able to rely on Cal-Am’s model results to accurately predict FWP, Weiss recommends additional data collection to address these data gaps, development of a consensus conceptual site model (CSM) and modifications of the model assumptions based on the CSM, and then calibration of the model to match the effects of these recent rainfall events.
2. The well field capture analysis presented in the project’s Final EIR/EIS appears to be flawed as it does not account for potential freshwater capture beyond the identified capture zone of the well field due to seaward gradients. If such capture is greater than what is already accounted for, it will decrease the ocean water percentage (OWP) in water extracted by the well field. The uncertainty in the range of OWP depends on how the hydrogeology of the Dune Sand Aquifer and underlying Fort Ord Salinas Valley Aquitard (FO-SVA) is interpreted and modeled. It could be reduced through adjustments to the groundwater model and applying it in non-superposition mode to more accurately reflect the site hydrogeology and implications of the TSW pumping results.
3. Potential project impacts on groundwater quantity and quality can be reduced by extending the planned well field intakes seaward by reducing the angle of slant of the wells or by using horizontal wells to shorten the seawater flow path to the well field intakes, thereby increasing the OWP and decreasing the size of the landward capture zone.
RECOMMENDATION
To obtain a more accurate and definitive groundwater capture zone and OWP estimates due to proposed pumping from the MRWSP well field, it is recommended that additional hydrogeologic data be obtained from the 2 square-mile area east of MW-7S so that a single CSM can be accepted to represent that area. In addition, the area west of MW-7, between MW-4 and MW-7, should be investigated to determine potential aquitards contiguous with those at MW-7, and vertical groundwater gradients between the Dune Sand Aquifer and 180-Foot Aquifer. The new data should be incorporated into NMGWM, 2016 which should be modified as follows:
• Change the thickness of the FO-SVA (Layer 3) inland from MW-7, and configure so that the top and bottom of Layer 3 approximates the configuration depicted in the geologic cross-section, such that the top resembles a “stair-step” surface;
• Potentially divide Layer 2 into two or more layers;
• Increase the HK of the Dune Sand Aquifer (Layer 2) in parameter Zones 16 and 20, currently modeled with HK of 2 and 4 ft/day, respectively, to values in the range of 50 to 200 ft/day, more akin to the actual HK for dune sand, and in the middle of the range in values from other sources (Figure 27); and
• Modify HK and VK as appropriate in Layers 2, 3, and 4 of the model in the vicinity of the well field, such that drawdowns in more distant wells, particularly MW-4 and MW-7, are in accord with those estimated from a conservative extrapolation of the TSW drawdown data.
Along with these changes, the model should be run in non-superposition mode in a range of scenarios, and flow lines plotted to illustrate the revised capture pattern. Mass balance information should be obtained for those portions of the model affected by groundwater flow to the well field, and from the Dune Sand Aquifer to the 180-Foot Aquifer, and used to calculate new fresh water capture and OWP estimates.

ABSTRACT: STAFF REPORT: RECOMMENDATION ON APPEAL SUBSTANTIAL ISSUE & DE NOVO HEARING and CONSOLIDATED COASTAL DEVELOPMENT PERMIT
Appeal No: A-3-MRA-19-0034
Local Government: City of Marina
Decision: Denial
Application No.: 9-19-0918
Applicant: California American Water Company
Appellants: California American Water Company, Brian LeNeve, Castroville Community Services District, and Commissioners Howell and Uranga
Project Location: Wellfield at the site of the CEMEX, Incorporated sand mining facility in the City of Marina, Monterey County, and pipelines and associated infrastructure within the Cities of Marina and Seaside, the County of Monterey, and the Commission’s retained jurisdiction.
Project Description: Construct and operate a slant well field, associated water transmission pipelines and related infrastructure within the coastal zone to support a proposed desalination facility located inland of the coastal zone.
Staff Recommendation: Substantial Issue Exists; Denial of De Novo Permit; Denial of Regular Permit

STAFF NOTE: This staff report does not currently include a section analyzing the potential groundwater impacts of the proposed project. Due to delays caused by power outages and wildfires, the independent hydrogeologist that the Commission hired to assess hydrogeological impacts has had to delay issuance of his report, which has necessarily delayed this portion of the staff report. Given the complexity of the proposed project, however, and the significant public interest in the project, staff is issuing this staff report early, even without this section, so that the public will have additional time to review the lengthy report. A revised version of this report will be posted on Friday, November 1, that will include the groundwater analysis.

The STAFF REPORT: RECOMMENDATION ON APPEAL SUBSTANTIAL ISSUE & DE NOVO HEARING and CONSOLIDATED COASTAL DEVELOPMENT PERMIT and EXHIBITS document copies are embedded.
