Questions for the release of the Delta Conveyance benefit-cost analysis

This evening, I learned that the long-awaited benefit-cost analysis for the Delta Conveyance Facility (DCF) is being released tomorrow morning.  DWR put out an FAQ in advance of the release last week, but it didn't include any of the questions below - so perhaps someone who is invited can ask them directly.  Dr. Sunding did these analyses in the 2010s for the WaterFix, including an analysis of a single-tunnel option.  His old analysis of a single-tunnel WaterFix suggests the current single-tunnel DCF would fail his own benefit-cost analysis, as I explained in the past here and here, because the DCF water supply benefits are lower and the costs higher than in 2018.  Perhaps this is why we have had to wait so long for this update, it must take a lot of time and creativity to figure out a way to increase the benefits. (Note: This first paragraph was revised 5/16 9:30 AM, the morning after the original post.)

This report is being released over five years after Governor Newsom directed DWR to switch to a single-tunnel plan, and nearly two years after DWR released the details of its preferred project design in the Draft EIR.  The Final EIR was released last year.  
Should benefit-cost analysis be conducted before or after an alternative is selected?

When WaterFix considered switching to a single-tunnel, staged implementation, you produced a benefit-cost analysis for a single-tunnel alternative in a few months.  
Why did it take so long to release this report?  

In your WaterFix benefit-cost analyses in the 2010s, you did not use the same no-tunnel baseline and project description as the EIR, and you did not include any environmental costs.
In this analysis of the DCF, are you being consistent with the EIR baseline and project description?  
If not following the EIR.  Why?  
Does this analysis include environmental costs of the tunnel?

None of the previous analyses you did for the WaterFix were ever submitted to the State Water Board or the Delta Stewardship Council as evidence that the WaterFix was in the public interest.
Why not?  
Will this analysis be added to the current petition before the State Board?  

In your WaterFix benefit-cost analysis, you found that expected economic benefits from earthquake risk reduction due to the tunnels were relatively small.
Are your current findings the same?  If not, why?
Considering the fatalities, infrastructure and property loss from mass levee failure, is a water tunnel the best way for the State to address this risk?
Have you done benefit-cost analysis comparing levee investments to a water tunnel to address earthquakes and flood risk?

The Central Valley Project, which was supposed to pay 45% of the cost of WaterFix, has already decided not to participate in the DCF due to cost.  Several agriculture serving State Water Project agencies are also declining to participate due to costs.
What does your analysis say about whether the remaining agricultural water suppliers can afford their share of the DCF?
Does your analysis predict that agricultural water agencies will stick with the project, or does it predict that more agricultural water users will drop out of the project?

Metropolitan Water District’s sales have declined in recent years, and population has declined in its service area.  Its 10-year financial projection forecasts rates will increase at 3-times the expected rate of inflation over the next decade with flat or declining water sales.  
Does your analysis project increasing or decreasing water demand for MWD?
Have you analyzed its ratepayers and member agencies capacity to pay for the tunnel?

In your other work, you have written a lot about how uncertainty reduces the benefits of investing in a project, including regulatory uncertainty.  There is a lot of uncertainty about how the DCF will be operated, including uncertainty about environmental effects.  Adaptive management is part of the plan.  
Did you reduce your estimates of benefits to account for uncertainty?
Did you account for uncertainty in the estimates of cost?
___________________________________________________________________________________
Last week, DWR released an FAQ document that reserved its only call-out for 4 bullet points describing “benefits of the Delta Conveyance Project will not be quantified in the benefit-cost analysis and yet are also compelling for decisions-makers.”  These comments and questions are regarding these four bullet points in the FAQ.  

Groundwater supplies.  In previous studies of WaterFix benefits and costs, Dr. Sunding explicitly accounted for constrained ground water supplies and limits on groundwater pumping, it significantly increased the value of water supplies to farms. It seems likely that DWR’s statement about this in its FAQ is false and these benefits are quantified in the benefit-cost analysis.
Are constraints on groundwater included in the valuation of water supply benefits?

Job creation.  You have estimated jobs created from tunnel construction, which DWR calls a benefit in its FAQ document describing your report. 
If the costs increased, wouldn’t the jobs increase too? 
Have you ever said that jobs are a measure of costs not benefits with respect to benefit-cost analysis?
If funds were spent on tunnel alternatives instead of DCF, how many jobs would be created? 
When higher water rates reduce household income, how many jobs are lost?
For every dollar spent, do tunnel alternatives create more or fewer jobs than the tunnel?

Increased Operational Flexibility:  Like groundwater benefits, this could be included in the benefit estimates for water supply and water quality.  This issue does raise questions about whether DWR intends to actually operate the tunnels as described in the EIR.  Regarding tunnel operations, the EIR states that “Shifting from south Delta intakes to proposed north Delta intakes has trade-offs and is not expected…” 
Do your benefit estimates reflect flexibility from the project operations in the EIR?

Delta Community Benefits Program:  The program is speculative and undefined.  Funding is expected to be minimal.  Is funding for this undefined program included in the cost estimate? If not, it shouldn’t be mentioned here. 

[5/19 Note: I have seen the report now and it is a lot different than the WaterFix reports, and thus it answered quite a few of these questions. Most importantly, it doesn't change the project description from the EIR, the biggest problem with the old WaterFix reports.  But the new analysis does some new things that are also very questionable.  I'll leave this post up as the blog is a personal journal, but note the date, 5/15.  There will be more analysis, some of it on this blog.]

Is DWR Lying About The Low-Utilization Operating Plan For The Delta Conveyance Project?

The most significant change from the twin-tunnel, three-intake, 9,000cfs capacity WaterFix to the single-tunnel, two-intake, 6,000cfs capacity Delta Conveyance Project (DCP) isn't the number of tunnels, but how they are utilized.  

It would seem logical that lowering the capacity of the Delta tunnel(s) would result in the remaining capacity being used more intensively. That was how it worked when DWR briefly switched to a staged, single-tunnel plan for the WaterFix in 2017, as well as other alternatives with lower capacity.  

Instead, the draft EIR for the single-tunnel DCP states that the tunnel will be used much less than the WaterFix twin-tunnels.  In fact, the operation modeling shows zero diversions through the tunnel most of the time.  In the DCP, the tunnel only makes up 13.5% of projected Delta water exports, compared to 50% of total Delta water exports in the WaterFix.  

Is this low-utilization rate of the DCP believable?  Will the state spend $20 billion on the most expensive water infrastructure project in history and not operate it most of the time (or as Osha Meserve said, why buy a Maserati and only drive 10 miles per hour)?  

That is indeed the official plan as described in chapter 3 in the EIR, and subsequently used in all the analytical chapters that follow. 

However, the Draft EIR itself contradicts these operations in chapter 2: Purpose and Objectives and in and Appendix 3a where it interprets and elaborates on the purpose to screen out all alternatives.  The project objective is to achieve the following 4 purposes in a cost-effective manner.
1. Climate resiliency
2. Seismic resiliency
3. Water Supply for State Water Project
4. Operational Flexibility

The problem is that achieving 3 out of the 4 project purposes, as described in the alternatives analysis in Appendix 3A, require shifting diversions from the south Delta to the north Delta intakes and through the tunnel.  In other words, 3/4 of the stated project goals are in conflict with the project description and EIR modeling which focuses exclusively on a low-utilization scenario.

Goal 1, Climate resiliency:  Appendix 3A states that only tunnel alternatives satisfy climate resiliency because they can divert from the north when the south is too salty. Stunningly, this flat out ignores the water quality commitments and limited north delta diversion in the actual project description.  (In Appendix 4A, the EIR models a climate change scenario, and finds that there are actually fewer days on the calendar that the tunnel can be used under climate change.  Thus the incremental water supply benefit decreases as climate change accelerates, in contrast to Appendix 3A that assumes higher tunnel use under climate change when screening out other alternatives.)

Goal 2, Seismic resiliency:  Appendix 3A assumes that if brackish water fills the Delta in a seismic-induced mega-flood, then the north Delta intakes and tunnel will be used intensively in place of the south Delta pumps which would be unavailable for months due to bad water quality. This assumption is inconsistent with the project description which commits to operating the project to support Delta water quality objectives and limits use of the north Delta intakes. The EIR provides no explanation of why the environmental restrictions and water quality objectives in the Delta would be waived in such a scenario where the Delta communities and environment are experiencing an emergency, and it provides no modeling of the environmental impacts of operations in such a case.

Goal 4, Operational flexibility: Appendix 3A describes this as a certain kind of flexibility - shifting south Delta diversions to the north Delta. Again, directly in conflict with the project description which does not include such flexibility or any analysis of the environmental impacts of this alternative operating scenario.

The final part of the project goal, which is the only one not in the Appendix 3A screening criteria, is to achieve the goals in a cost-effective way.  The EIR is completely silent on cost-effectiveness, but this is another goal that would seem to be in conflict with the low-utilization of the tunnel in the project description.

So back to my original question: Is DWR being truthful?  Will they really keep the north Delta intakes off and the tunnels empty most of the time?

The alternatives analysis and how it interprets the project goals show they are not really committed to the low-utilization project description.  When this is combined with the lack of economic and financial feasibility analysis, I believe the project description lacks credibility.  

While it is tempting to rate the EIR project description as "Pants on Fire" on the Truth-o-Meter, I'll keep my rating at "lacks credibility" or "inadequate support" as I am sure there are honest folks who worked on this draft EIR who truly believe in their $20 billion mostly-empty tunnel proposal. 

In summary, the DCP EIR has many problems, and I have only touched on one of them here.  As a result, I believe this single-tunnel proposal will fail like the twin-tunnel proposals that preceded it.

The CVP "No Harm" deal for the Delta Tunnels does a lot of harm to MWD's business case for their $12+ billion investment.

Why did the Central Valley Project want a "Do No Harm" agreement about the delta tunnels?

Last year, Central Valley Project (CVP) contractors made a rational and predictable decision not to pay their share of the WaterFix.  To save the project, Metropolitan Water District (MWD) staff convinced their board to add a multi-billion dollar blank check to fill the enormous financial hole.  To do so, MWD staff argued that the extra funding would allow them to receive the benefits that the CVP would have gotten from their investment.  MWD staff did this with a highly speculative estimate of future water supply benefits from financing the second of the twin tunnels, the so-called "unsubscribed capacity".   Last June, I wrote...
"when MWD staff is using this speculative no-tunnel baseline assumption to define the additional water supply benefits they will receive for the extra investment, the additional water supply is water that goes to the CVP under current regulations.  Thus, in this unsubscribed capacity scheme, MWD staff is using this speculative future baseline to argue that financing the full WaterFix will give them control of water supply that CVP currently diverts from the south Delta...  MWD board members should be very, very skeptical that it will actually work that way."
In testimony before the State Water Resource Control Board this summer, I presented the following estimates of average annual water deliveries (in acre feet) derived directly from the information MWD staff presented to their board in order to persuade them to commit additional billions from their ratepayers.  The second line is the MWD staff scenario where CVP pays MWD to use all the 33% "unsubscribed capacity" and the 3rd line is the MWD staff scenario where CVP doesn't pay and the 33% capacity is utilized by MWD.


CVP
SWP
Total
No Action Alternative
2,115,000
2,585,000
4,700,000
CWF (67% SWP/33% CVP)
2,094,000
2,906,000
5,000,000
CWF (67% SWP/33% MWD)
1,665,000
3,056,000
4,721,000

The second line shows no water supply benefit for CVP compared to No Action.  Comparing the first line to the last line where MWD pays for the CVP share shows that according to MWD staff, the primary effect of implementing WaterFix is to redistribute 450,000 acre feet of water from the CVP to MWD.  The incentive of the CVP to participate in WaterFix is to avoid this potential harm.  Thus, it's not hard to see why the CVP would want a "no harm" agreement regarding the future effects of California WaterFix (CWF).

MWD staff would argue that a "no harm" agreement doesn't change their water supply benefit because under the agreement, they only have to compensate CVP for impacts that are attributable to the WaterFix.  They would argue that the decreased CVP water supply is due to regulations on south Delta pumping that they argue are equally likely with or without the WaterFix, thus there is no problem.  Are they right? 

To answer this, you should look at the official WaterFix documents, and ignore the sales pitch from MWD staff and other WaterFix proponents.  That is certainly what a court will do.  The "No Harm" agreement states that the WaterFix is described by the Final WaterFix EIR/EIS, and that document clearly states that the new OMR regulations and other more restrictive operating criteria are part of the WaterFix project itself, and are included as a response to expected environmental changes caused by operating the tunnels and the new north Delta intakes.  As an example, here is a quote from the Final EIR/EIS
“These newly proposed OMR criteria (and associated head of Old River gate operations) are in response to expected changes under the PA, and only applicable after the proposed north Delta diversion becomes operational." (note: PA stands for "proposed action" which is the WaterFix)
Thus, it seems pretty clear to me that the "No Harm" means the CVP can't lose any water supply as a result of these new regulations that are clearly defined in the EIR/EIS as an integral part of the WaterFix project.  The agreement is not specific about how the CVP would be compensated, but it seems likely that they will have to receive water delivered through tunnels without paying for the tunnels.  Thus, the water supply benefits to MWD will be significantly less than the MWD board was told when approving the extra billions.

The "no harm" agreement also reduces the already remote chance that MWD will ever be reimbursed by the CVP for its investment in the second tunnel.  The argument pushed by MWD and DWR that farmers/CVP would pay them back for the 2nd tunnel has always been as laughable as President Trump's claims that Mexico will reimburse the cost of his border wall, and this "no harm" agreement makes it even more clear.

In addition to this "no harm" agreement, the new coordinating operating agreement between the SWP and CVP could also greatly affect the water supply benefits of the WaterFix to MWD.  Nine months ago, MWD staff described a "Master Agreement" with DWR that defined MWD's use and control of the 2nd tunnel, but that agreement still has not been made public despite MWD staff promises.  MWD staff description of this "Master Agreement" was key to the MWD board's funding vote, but it seems to conflict with this new "Do No Harm" agreement with the CVP.

The bottom line is that these new agreements appear to substantially reduce promised water supply benefits to MWD ratepayers while increasing their share of the costs.  In order for the MWD board to fulfill their fiduciary duty to their ratepayers, they need to fully review the effects of these significant new agreements on the WaterFix return on investment and potentially reconsider their previous funding commitments.

New WaterFix Economic Analysis is Even Worse Than I Originally Thought

It turns out my initial reaction to the Brattle Group's latest WaterFix benefit-cost analysis was too nice.  I am receiving feedback that the sea-level rise analysis that the Department of Water Resources' touts as "innovative" assumes WaterFix is operated in ways that harm fish, would violate state and federal laws, and contradicts the commitments that DWR is making about WaterFix to the State Water Resources Control Board and other regulatory bodies.  My quick take didn't mention any of these important fish or legal issues.  

This quote from the Brattle/Sunding report explains its justification for estimating an enormous new sea-level rise benefit from WaterFix.
"DWR modeling indicates that Delta exports are highly sensitive with respect to sea level rise. A rise in sea level means more salinity intrusion from the ocean via the San Francisco Bay, affecting the water quality of exports and requiring more fresh water to be released from upstream reservoirs to meet salinity standards. By 2100, a 2-foot sea level rise becomes a more important contributor to reduced annual south-of-Delta export than does annual inflow change, a result also shown by Fleenor et al. (2008).  The DWR study published by Wang et al. (2011) concludes that sea level rise can be expected to reduce Delta exports by over 119,000 acre-feet annually by mid-century, and by over 520,000 acre-feet annually by 2100. Construction of the WaterFix would prevent these losses by giving water managers the capability to divert water directly from the Sacramento River upstream of the Delta.”
I asked several knowledgeable experts if this was legitimate and received a resounding "No."  Here is an example,
There is no reason to think that building the tunnels will allow a change in water quality standards.  Those standards protect fish and wildlife (the “X2 standards”) and in-Delta agricultural, municipal and industrial uses.  The studies Sunding relied upon (without any apparent understanding on his part of how they were done, what they mean and what their assumptions were) show that with expected sea level rise and assuming no islands flood and all channels get deeper—so they continue to be dredged to the same levels as they are now even though they don’t need to be—more outflow will be needed to meet the current water quality standards.  
Sunding assumes, quite incorrectly, that with the tunnels the extra outflow caused by sealevel rise can instead be pumped through the tunnels, which means the Delta gets saltier and the water quality standards won’t be met.  That would be a disaster for fish, wildlife and those in the Delta who rely upon it for water.  Assuming the water quality standards go away because the tunnels are built is either fantasyland or the worst fears of the in-Delta water users and enviros.  It means either Sunding has no clue about Delta water quality and the reason for those standards, or he and his clients think they can fool people into thinking this project works economically or he and his clients are completely disingenuous about their intentions once the tunnels are built.  So once again, Sunding’s assumptions are complete BS.
Yes, there is quite a track record of Brattle/Sunding making unjustified assumptions to increase the estimated benefits of the tunnels.  Every revision of the tunnels project has made its economics worse, but Brattle/Sunding just make another new assumption to push the benefit-cost ratio over the magic number of 1.

Summer 2012:  After the initial analysis of economic benefits of the Delta tunnels (water supply, water quality, and seismic risk reduction) falls far short of its costs, Sunding/Brattle unveil a new 4th category of benefits bigger than all the rest combined:  "the value of regulatory certainty."  The justification for the benefits are the regulatory assurances that are part of a habitat conservation plan under the ESA.  Critics call regulatory certainty a BS assumption.

Summer 2015:  DWR releases new EIR and revised tunnel plan that shifts from BDCP habitat conservation plan to tunnels only WaterFix.  The new EIR also has substantially lower water supply benefits compared to no action.  Both these changes substantially impact the economic benefits of the tunnels, and DWR promised a new economic analysis within months but never releases it.

Fall 2016:  The suppressed 2015 economic analysis comes out in a public records request.  In order to get a positive B-C ratio in this report, Brattle/Sunding assume away $6.5 billion in costs by assuming a massive, unjustified subsidy.  They also assume the water supply benefit of the tunnels are more than 5 times higher than estimated in the EIR/EIS by continuing to assume the tunnels are exempt from future regulations that are certain without the tunnels.

September 2018:  As the economics of the tunnels get worse, the ridiculous assumptions needed to generate a positive benefit-cost ratio get bigger too.  The analysis released last week embeds a number of inaccurate assumptions:

  • Introduces unjustified $5.7 billion sea-level rise benefit discussed above which implicitly assumes WaterFix doesn't have to comply with Delta water quality standards.  Costs exceed benefits without this assumption.
  • Implicitly assumes the No Tunnel Scenario complies with proposed Bay-Delta outflow requirements, but that the WaterFix scenario does not.  This unjustified assumption increases estimated water supply benefit to more than 6 times the level in the WaterFix EIR/EIS.
  • Introduces a new multi-billion dollar cross subsidy from Metropolitan Water District ratepayers to the Central Valley Project in the form of a low "wheeling rate" for access to the tunnels' conveyance capacity.  
  • Falsely claims that an analysis that is not statewide, and only narrowly focused on participating water agencies, is consistent with the DWR economic analysis guidelines.

Quick Reaction to the Latest WaterFix Economic Analysis

This afternoon, the Department of Water Resources released a new report from the Brattle Group, "Economic Analysis of the WaterFix: Benefits and Costs to Project Participants."  I gave it a quick review this afternoon, and judging by my inbox, there is high demand for instant analysis - so here it is.

This report is different in several respects from previous analysis of earlier versions of WaterFix by the same consultants.  These 4 points highlight this new information.  The 1st and 4th bullet points in this list are going to cause trouble for the Metropolitan Water District (MWD) in the recent Prop 13 and Prop 26 lawsuit filed against them.
  • It assumes a massive new subsidy for agricultural users cost share from urban water users.  The agricultural subsidy is contained within a "wheeling rate" that it assumes that Metropolitan Water District (MWD) would charge the Central Valley Project (CVP) for using the tunnels' conveyance capacity.  To illustrate this, I used Table 2 and Table 6-7 in the report to calculate the % of water supply benefit and % of project costs for 3 groups, State Water Project Urban (which is mostly MWD), SWP Agricultural, and CVP (which is mostly farms).  
SWP Urban SWP Ag CVP
% of Water Yield 44% 24% 32%
% of Costs 63-69% 14-19% 18%
(The % costs is a range because it is unclear whether table 6 or 7 is comparable to the water yield estimates in table 2.  Either way the urban to agriculture subsidy is clear.)
  • The positive benefit-cost ratio depends on a dubious new benefit: the value of sea-level rise protection benefits.  The report estimates the present value of these sea-level rise benefits at a whopping $5.7 billion, a value that exceeds the study's estimated total net benefit of the WaterFix.  That means the benefit-cost ratio is negative for all user categories if this dubious new benefit is removed.  This estimated benefit has never been included in any previous study of WaterFix, and thus it is a new benefit category created for this report when the old methodology fell short of giving a postive benefit-cost ratio.  So how is it estimated?  They use a 2011 DWR report that estimates the water supply loss from maintaining Delta salinity standards under sea-level rise scenarios using the existing no-tunnel system.  Then it assumes that WaterFix eliminates 100% of that loss, which seems to assume that they won't have to meet the salinity standards if they can divert from the new intakes further upstream.  Thus, it seems that this benefit to WaterFix benefits comes at the cost of non-participants downstream from the north Delta intakes.  Those costs are not included in this analysis of benefits/costs, because it only looks at participants.  Furthermore, it is worth noting that the study from which these water supply benefits are calculated does not include any modeling of the Waterfix tunnels operation, and thus it is not clear that the WaterFix would/could prevent this loss.  Why didn't DWR model this with WaterFix?  Why use an old study and make this unjustified assumption?
  • The report, press release and webpage falsely claim that this benefit-cost analysis is consistent with DWR's Economic Analysis Guidebook.  The Economic Analysis Guidebook clearly states that "Although economic analyses can be evaluated from many different perspectives (individuals, communities, etc.), DWR conducts these analyses from a statewide perspective."  The report is clear, even in its title, that it is an analysis from the perspective of water agencies that participate in WaterFix.  It does not consider statewide impacts - which include costs to other water users or the environment - both of which are very large for this project.  This is especially true if one uses the No Tunnel baseline used in this economic study which is extremely different than the No Tunnel baseline used in the environmental impact report and other regulatory documents.
  • The single-tunnel scenario is clearly better for MWD and urban water users if one compares this study to a February 2018 analysis of single-tunnel by the same consulting firm.  While that single-tunnel report had many of the same problems as this one, it did not need to include a highly questionable estimate of over $5 billion in sea-level rise benefits to get a positive benefit-cost ratio.  Comparing these reports shows that financing the 2nd tunnel by MWD adds enormous costs for their ratepayers for little/no additional benefit.   
Serious problems with previous reports, especially the use of a deceptive no project baseline to artificially increase water supply benefits, are repeated in this report.  I have written about that extensively elsewhere and will not repeat it here.  I may amend this analysis later once I have time to review in more detail.

Three Days Before MWD's Revote On Financing the Delta Tunnels, A New Regulatory Document Further Multiplies The Investment Risk

The Metropolitan Water District re-votes on their plan to finance the majority of the $17+ Delta tunnels plan tomorrow.  Over the weekend, I reviewed the information MWD staff prepared for their vote, along with the new Sacramento-Delta report released by the State Water Board on Friday that is likely to substantially reduce the water supply benefits of the tunnels.

  1. Master Agreement for the 3,000 cfs unsubscribed capacity.  (In March, staff promised this ASAP, but still nothing 3+ months later)
  2. Legal Opinions of financing additional 3,000 cfs capacity: Prop 26/128, water rights
  3. Benefit/cost analysis of financing the additional 3,000 cfs capacity
  4. Real evidence to support staff expectation that CVP will lease back the capacity (not more talk from staff who have been wrong about farmers paying for the last 10 years)
After Friday's release by the State Board, I would add to the top of this list an analysis of how the State Board's Sacramento-Delta framework will affect water supply from the tunnels.  The Delta outflow recommendations in this new document would reduce diversions from the Sacramento/Delta watershed by an estimated 2 million acre feet per year compared to existing conditions (with or without the tunnels).  Not all of that would be the responsibility of the SWP and CVP, but the document does state "The Projects (SWP/CVP) would bear a significant portion of that responsibility since they are the largest, most junior diverters in the watershed..."

These new outflow regulations will have major impacts on this slide that has been at the heart of the MWD staff argument that WaterFix is a good investment.  

MWD staff's "Future without CA WaterFix," cuts Delta exports by 1 maf over "Existing Conditions."  This future scenario looks more likely now, and it would go a long way towards meeting the Board's proposed outflow requirement that would cut diversions by 2 maf.  On the other hand, it is pretty much impossible to see how the "Future with CA WaterFix" scenario could occur and meet the outflow requirement of the Board.  As mentioned above, the Board says "The Projects would bear a significant portion of that responsibility" but under this Future with CA WaterFix scenario, the Projects would increase diversions compared to Existing conditions and wouldn't be contributing anything.  

Thus, the new Sacramento/Delta outflow rules are likely to push the bar on the far right (water exports with the WaterFix) down, and thus will push the estimated water yield from the tunnels way down and the difference between these two bars should be much smaller.  I would argue that the EIR/EIS project yield of 0.2 maf looks like a better assumption than staff's 1.3 maf of water yield.  As the yield declines, the cost per acre foot rises rapidly and WaterFix becomes a worse investment for MWD.

The MWD board would be well advised to redirect the billions they would invest into WaterFix into alternative projects that will yield more water per dollar invested while furthering the state's goal to reduce reliance on the Delta.
-----------------------------------------------------------------------------------------
Finally, I should mention the two changes in what MWD staff has provided to the board in the July 10 packet compared to the April 10 vote.  

First, the July 10 agenda does not include a single-tunnel option for the board.  Staff says this is no longer an option, pointing to a letter from a Department of Water Resources lawyer saying DWR is no longer considering a "staged" single-tunnel plan.  The MWD Board should not accept that flimsy  dismissal of the single-tunnel option.  DWR only said that because the MWD board voted to finance the 2nd tunnel on April 10.  

Should the MWD board rationally choose not to fund both tunnels now, a one-tunnel plan will be back in consideration.  For precedent, look at what Santa Clara Valley Water District did last fall - they voted to support a single-tunnel concept when there was no single-tunnel proposal - and suddenly that became the plan.  The real concern is the time pressure created by the end of Governor Brown's term.  It is probably true that the twin tunnel proposal will die if it is not approved before the end of his term, but I don't think the same can be said of the urban, single-tunnel option.  As I recall, Gavin Newsom has said that he supports the concept.  While I think no tunnel is the right answer for California, I would agree that single-tunnel is a better and less risky option for MWD than this "unsubscribed capacity" two-tunnel strategy. 

The second important change to the July 10 packet was a new estimate of the additional water supply MWD could get from the 3,000 cfs unsubcribed capacity if CVP did not lease it from them, 150,000 af.  Staff had not been clear about this before, and it seemed like some board members thought they would get 433,000 af in additional water supply if CVP didn't lease capacity (the same benefit estimated for CVP), but this extra capacity would deliver about 1/3 the water supply benefit to MWD than it would deliver to CVP.   Financing the unsubscribed capacity would increase MWD's cost for the tunnels by more than 100%, while increasing their water supply benefit by less than 20% at best (perhaps nothing at all given the state board's newly announced plan for increased outflow).

MWD staff's plan to fund 65% of the twin-tunnels is a bad deal that keeps getting worse for MWD ratepayers.  Fortunately, MWD board members have another opportunity to vote and they have plenty of good reasons to change course.

New WaterFix Financial Plan Is Extremely Risky. Will MWD Board Reconsider Their Vote on July 10?

On April 10, Metropolitan Water District (MWD) approved, with little analysis, a hastily conceived plan that greatly increases their "Waterfix" commitment from $4.3 billion to a blank check for 65% of the project (currently estimated at $10.8 billion).  Most of the additional cost is from MWD committing to finance the project's "unsubscribed capacity," which is defined as 1/3 of the $17+ billion project.  The "unsubscribed capacity" exists because the agricultural serving Central Valley Project made a rational decision not to finance their share of the $17+ billion Waterfix tunnels, and MWD's last minute reversal is a desperate attempt to fill this financial hole and get it approved before the full risks of the plan can be understood.  While this vote commits MWD to 65%, they are also negotiating exchanges with State Water Project agricultural contractors for portions of the other 35%, so it seems probable that MWD's final share will be 75% or more.
 
Due to likely Brown Act violations, MWD will be revoting on the additional financing on July 10.  In a letter denying the Brown Act violation while announcing the revote, MWD argues that there was no violation because the vote must be viewed in light of the "robust discussion" around the tunnels in over 10 years of planning.  I agree with that, this last minute change to the financial plan must be viewed in light of 10 years of staff describing a completely different financial scenario; ten years of staff wrongly stating that farmers will pay for the majority of the project; ten years of staff insisting MWD's share is only 26%; ten years of staff saying there will be no farm subsidies; and ten years of staff dismissing analysis (by me and others) that correctly predicted that farmers would and could not pay their share and that MWD ratepayers or taxpayers would subsidize the project. 

In fact, most of the agenda packet for the meeting in which MWD commits an additional $6.5+ billion to the project are white papers and analysis that do not even contemplate that MWD would pay more than $4.3 billion, or how non-participation of the CVP could affect project operation.  This new deal hasn't received a fraction of the previous analysis, and it is clear that many are uninformed and confused about what this change means.  MWD staff say that CVP agricultural contractors are expected to pay them back in the future by renting the tunnel capacity from them, a plan with remarkable parallels President Trump's plan to have Mexico reimburse U.S. taxpayers for building his border wall if Congress approves up front financing

MWD board members still do not have key information they need to consider before making risky, multi-billion dollar commitment from their ratepayers.  This information includes:
  • The "Master Agreement" with DWR that describes the management of the "unsubscribed capacity."  The board wasn't even provided a draft agreement, just a powerpoint slide that lists what staff hopes will be in this critical agreement.
  • An analysis of whether the unsubscribed capacity arrangement in the master agreement will stand up to legal challenge, does not infringe on others water rights, and complies with the California constitution (notably Propositions 218 and 26).
  • An independent benefit-cost and financial analysis of the additional "unsubscribed capacity" investment, including a robust analysis of risks and unintended consequences. 
  • Since staff argue they will be repaid by CVP farmers, they should provide some evidence that this expectation is reasonable.  If they couldn't get a formal agreement, it seems there should be a minimal expectation of a letter of support from CVP that signals their intent to use and pay for this capacity.  In addition, how about a serious independent analysis that shows why it would be in CVP farmers economic interest to pay these costs.
Last weekend, I finally watched the March 27 workshop meeting where staff reviewed the unsubscribed capacity deal.  As far as I can tell, this meeting is the only information on the unsubscribed capacity deal prior to the vote, and months later, is still the best information out there.  I found the meeting alarming.  MWD staff did not adequately convey the risk of the financing scheme to the board, and made a number of questionable and misleading statements throughout the meeting.  Some of the board members (those who voted No on April 10) asked good questions, but did not receive good answers from staff.

Below are some more specific comments on this financial plan after watching the March 27 workshop. 

This deal increases the already high risk that the tunnels will never provide the additional 1.3 million acre feet (maf) of water supply reliability claimed by MWD staff.     

The 1.3 maf of water supply benefits is the result of MWD staff using an alternative no-tunnel baseline than is used in the EIR/EIS and various regulatory permits for the tunnel.  In the WaterFix permit documents, the incremental water supply benefit is just 0.2 maf, not 1.3 maf, because the no-action baseline is different.  The difference between the MWD staff estimate of 1.3 maf, and the 0.2 maf in the EIR/EIS, is that the official permit project description includes new south Delta pumping restrictions as part of the WaterFix project, whereas the staff analysis puts these new south Delta pumping restrictions into the no-tunnel baseline (and thus takes them out of the WaterFix project).

When all the SWP and CVP contractors are participating equally, this baseline argument is kind of abstract and academic although it is critical to the assessment of the benefits, costs, and environmental impacts of the tunnels.  However, it is no longer an academic debate when the CVP is out and MWD is financing "unsubscribed capacity." When all entities are participating, the touted 1.3 maf water supply benefit are the 2 projects working together to "protect" water they are currently diverting from future reductions.  But when MWD staff is using this speculative no-tunnel baseline assumption to define the additional water supply benefits they will receive for the extra investment, the additional water supply is water that goes to the CVP under current regulations.  Thus, in this unsubscribed capacity scheme, MWD staff is using this speculative future baseline to argue that financing the full WaterFix will give them control of water supply that CVP currently diverts from the south Delta.  That is a very different argument, and MWD board members should be very, very skeptical of that it will actually work that way.

Surprisingly, MWD staff patted themselves on the back for being consistent with this 1.3 maf yield assumption since way back in the BDCP days.  Stubbornly maintaining the same wrong position even as the facts change is nothing to boast about.  It was a speculative assumption under BDCP, but MWD staff stuck with the 1.3 maf water yield estimate even though shifting from BDCP to WaterFix (and losing the BDCP's section 10 ESA permit) reduced the primary rationale for this assumption.  And now the non-participation of the CVP further reduces the justification for this optimistic water supply assumption, but MWD staff is sticking with it - just like they stuck with their claim farmers would pay.  Good luck wrestling that water away from the CVP if they don't pay for the tunnels (not to mention environmental needs).

Financing "unsubscribed capacity" substantially increases project risks.  Three of the projects' biggest risks to MWD are amplified by this deal.
  • Cost overruns.
  • Farmers don't pay.
  • Future environmental regulations restrict the north delta intakes.
These have been big risks for MWD all along, but they are magnified here because this deal makes them positively correlated.  For example, if the project has construction cost overruns like most megaprojects - it greatly increases the risk that farmers will choose not to pay MWD to use the "unsubscribed capacity" because the costs will be too high.  In contrast, in the framework staff described for 10 years, all participants would have been equally on the hook for cost overruns, but the vast majority of cost overrun risk falls on MWD now.  In light of this, the MWD board should request an independent and updated cost estimate rather than rely on an old outdated, cost estimate.

As mentioned above, when the tunnels shifted from the BDCP to the WaterFix, MWD lost section 10 ESA assurances against future regulations and thus accepted much greater risk that the north Delta intakes could be restricted in the future.  That risk further increases with farmers not participating (which is more likely with cost overruns), because there will be a powerful political constituency arguing to pin future environmental problems in the Delta on the tunnels instead of the south Delta pumps where they divert.  The biological opinions and other analysis of the tunnels to date suggests that it won't be hard for the CVP to get scientific support for stronger restrictions on the north Delta instead of the south.  

MWD staff said they cared about risk reduction and wrote this principal on their powerpoint slides, but the reality is that this financial deal increases financial risk even more than the increase in their cost share.    

Staff comments about exchange contractors, wildlife refuges, and CVP ability to access the tunnels don't sound right.

In the meeting, staff argued that the CVP will not have any access to the tunnels, even if it means exchange contractors and wildlife refuges would receive diminished water supply.  I am pretty sure there are some lawyers with differing opinions on that one.  My first thought was to wonder if staffs claims about the effects of non-participation in WaterFix on CVP is consistent with this recent settlement between Friant and DWR.  If I were a MWD board member, I would be asking for an independent legal opinion on these issues.  

MWD staff is wrong that this financing approach maintains consistency with the approved project.

Maintaining consistency with the project that has received some permits (and is still under consideration for others) was touted as a major advantage to MWD financing the full 2-tunnel, 3-intake project rather than scaling down to a single-tunnel, "phased" approach.  While this keeps the physical infrastructure the same as in the permits, I am told that implementing the proposed "master agreement" in the way MWD staff describes would create big changes in operations (including upstream reservoirs, the south Delta intakes, and the distribution of export water south of the Delta).  Thus, it will result in big changes to the environmental and water supply impacts of the project, and could easily add permitting delays that are comparable to the single-tunnel approach.

Staff is wrong that farmers will repay them, and that the farmers need them to finance the "unsubscribed capacity" because of cash flow.  

Staff is right that this is a better deal for CVP farmers, but it is not for the reasons they say.  CVP farmers benefit from MWD financing the "unsubscribed capacity" deal because it a) shifts the risk of cost overruns and other problems from them to MWD, b) gives them a decade or two to find ways to shift their cost share onto someone else, and c) allows them to pass on the deal all together if it isn't beneficial to them (which it will not be unless a subsidy materializes).

With the cash flow during construction argument, MWD staff is just making something up that sounds plausible, but it is less credible than a pitch from a used car salesmen.  Westlands and CVP contractors can do the same thing while financing their share themselves by capitalizing some or all of the interest on the bonds.  Goldman Sachs described these options in their presentation to Westlands using a cash flow argument, and it is a common argument/structure for infrastructure bonds.  MWD staff claims that they would be repaid by farmers for fronting the money, including all the accumulated interest, which is no different to the CVP than financing it directly with capitalized interest.

Of course, staff also mentioned that the Sustainable Groundwater Management Act (SGMA) will make this water more valuable to farmers in the future.  They are right about that one.  The primary substitute for surface water is pumping groundwater, so SGMA will reduce access to that substitute and will increase the value of water.  I have seen estimates that it could drive willingness to pay up to $500 or $600 per acre foot.  There are some limits to high how it can go, as there are still other alternatives to get water than paying for the tunnels.  Lower cost options could include lobbyists, lawyers and campaign contributions, and the most costly options are to let the land growing less profitable crops go fallow, or go buy a farm somewhere else.  Even those high-cost options are likely to be cheaper than spending billions on tunnels for meager water supply improvement.

MWD staff made a terrible comparison between MWD's investment in the unsubcribed capacity to a private investor in a private/public partnership.

This analogy begs the question of why aren't private investors financing the unsubscribed capacity instead of MWD?  Unlike private investors in a public-private partnership, water agency staff (and boards) are risking other people's money, not their own.  Private investors would never touch this deal, and neither should MWD.

MWD staff blames the Bureau of Reclamation, but this financial mess is their own fault.

These financial issues were entirely predictable, and in fact were predicted 6 years ago.  MWD staff acts like the Bureau of Reclamation surprised them with an unexpected change.  Really?  No one ever seriously believed exchange contractors and wildlife refuges would pay because they don't benefit, and the CVP contractor with the most potential gain, Westlands, have been in doubt since the beginning and had their planning costs subsidized. 

This mess of a financial plan is a direct result of the Department of Water Resources (in alignment with MWD staff and state water contractors) to ignore their own guidelines about about feasibility studies and cost-benefit analysis, and their push back against every attempt to require an independent analysis of financial feasibility, and economic benefits and costs.  I can recall sitting in multiple Assembly hearings in recent years while MWD staff argued against bills that would have required the state to follow its own guidelines on financial feasibility and benefit-cost studies.  Rather than fighting against independent financial analysis along the way, MWD staff should have supported proper financial and economic analysis.  Then they could have been developing and analyzing the feasibility of alternative financing approaches years ago, not coming to their board with half-baked financial schemes at the last minute.

I am sure others have many more questions to add to mine.  Hopefully, MWD staff will take advantage of the additional time to fill-in the numerous critical information voids and provide their board with adequate information and analysis to make a commitment of this magnitude.  I am not expecting that, but maybe some MWD board members will use the opportunity to get more information and reconsider their vote.

Will the Metropolitan Water District Board Give Their Staff a Blank Check for WaterFix? Comparing language in MWD resolutions from October 2017 and April 2018

Last fall, when the Metropolitan Water District board voted to approve their share of WaterFix, the authorization of the General Manager was strictly limited to $4.3 billion (calculated as 26% of total estimated cost, but the limit was on the amount).

Tomorrow, the resolution before Board members does not limit the amount, but approves the General Manager to pay 64.6% of total project costs and grants the General Manager discretion in how the percentage is calculated.  While the staff report estimates this amount as "up to $10.8 billion," the actual resolution varies substantially from previous resolutions in that it does not include a specific dollar amount or any language to limit the total amount.  

This seems like a very substantial change to language that increases the financial obligation and risk to Metropolitan's ratepayers by much more than the difference between $10.8 billion and $4.3 billion.  I have pasted the relevant resolution language below.  Read it for yourself.

October 10, 2017 resolution: 

"2. Authorization of General Manager. The Board hereby authorizes the General Manager of the District, and any of the designees of the General Manager of the District, to do any and all things necessary or convenient in the best interests of the District to effect any financing of the California WaterFix through the Financing JPA (referred to herein as a “District Participation Action”) consistent with the CWF Project Arrangements, and to enter into any and all agreements and documents that the General Manager or his designee determines, in his or her sole discretion, to be necessary or convenient in the best interests of the District to carry out any District Participation Action, and to execute all papers, documents, certificates, agreements or other instruments that may be required in order to carry out any District Participation Action or to evidence said authority and its exercise; provided, however, that the District shall not make financial commitments to the California WaterFix in excess of $4.3 billion in 2017 dollars, which amounts to 25.9% of the estimated $16.7 billion in total capital costs of the California WaterFix. The term of bonds issued for the project shall not exceed 40 years and the total interest cost on debt issued will not exceed 8%. In implementing these actions, the General Manager of the District shall be authorized to use such reasonable assumptions, methods, approaches and calculations that it believes, in good faith, to be consistent with the authorizations herein and necessary to the implementation of the matters provided for in this Resolution." 

April 10, 2018 resolution:

"2. Authorization of General Manager. The Board hereby authorizes the General Manager of the District, and any of the designees of the General Manager of the District, to do any and all things necessary or convenient in the best interests of the District to effect any Unsubscribed Capacity Arrangements, and to negotiate, execute and deliver any and all agreements and documents that the General Manager or his designee determines, in his or her sole discretion, to be necessary or convenient in the best interests of the District to carry out any Unsubscribed Capacity Arrangement, and to execute all papers, documents, certificates, agreements or other instruments that may be required in order to carry out any Unsubscribed Capacity Arrangement or to evidence said authority and its exercise. 

3. Limitation of Authorization. The District shall not enter into any Unsubscribed Capacity Arrangement under Section 1 or 2 of this Resolution if, after giving effect to such Unsubscribed Capacity Arrangement, the District’s funding of such Unsubscribed Capacity Arrangement, together with the District’s estimated costs in its capacity as a State Water Project contractor, would commit the District to pay for more than 64.6% of the estimated costs of California WaterFix; provided, however, that the General Manager shall calculate the total amount of estimated costs of California WaterFix and the District's responsibility to pay for costs of California WaterFix based on such reasonable assumptions and methods as the General Manager shall determine in his or her reasonable discretion and judgment."

The Wall and The Tunnels: Multibillion dollar boondoggles share bait and switch financial plans and more


Donald Trump’s biggest campaign promise was building a $20+ billion wall along the Mexican border.  The financial plan:  “Mexico will pay!”

For a decade, Metropolitan Water District has been campaigning for the $16+ billion Delta tunnels.  The financial plan:  “Farmers will pay!”   Well, that hasn’t exactly been their line.  Instead, the promise has been, “The cost is the same as a latte a month” along with promises of “no subsidies for farmers.” 

There have been many dubious assumptions behind Met’s calculation that it will “only” cost the average southern California household a few dollars per month, but the biggest whopper has always been that Met’s ratepayers would only covering 25% of the bill – which meant Central Valley farmers would shoulder the vast majority of the costs.

Despite the fact that most knowledgeable people knew both Trump and Met’s financial claims were a joke, they stood by these myths when they were in campaign mode trying to build political support and a sense of inevitability behind their mega-projects.  But in recent months, both of them have faced the reality of switching from a political campaign to actually getting the billions of dollars needed to fund construction of their pet projects.

Trump has spent the past several month’s trying to get Congress to appropriate over $20+ billion for the wall, even threatening government shutdowns and a DACA solution in his effort to get taxpayers to pay.  His new financial promise:  “Congress will pay, but Mexico will reimburse us.” 

As first reported by the Sacramento Bee's Ryan Sabalow, Metropolitan is now trying to rush its board into voting to pay for the farmers share of the tunnels.  Met's new financial scheme: “Our ratepayers will pay, but the farmers will reimburse them.”

Congress has not agreed to pay for Trump’s wall.  Likewise, Metropolitan’s board should not agree to finance the Governor’s tunnels.  The Met board has been misled about financing the tunnels for a decade, and I would advise board members not to believe this latest plan either:  The farmers aren’t going to pay you back, AND you aren’t going to get a share of their water supply if they don’t. 

All the way back in 2012, I predicted in an economic analysis of the tunnels that they were financially infeasible unless urban ratepayers and/or taxpayers covered 90% of the cost.  I think that prediction is looking pretty good today.  It is certainly more accurate than the consultant and staff presentations the MWD board has been listening to for 10 years.

The parallels between the Tunnels and the Wall go beyond this synchronized pivot from “other people will pay” to “you will pay, but the other people will reimburse you.”  Both of these multi-billion dollar concrete mega-projects are not very effective at addressing the issue they are trying to solve. Furthermore, both of these projects are incredibly divisive concrete symbols of power that are truly offensive to large segments of the population.

For example, Congressman LuisGuiterrez famously tweeted this about the Wall, “It would be far cheaper to erect a 50-foot concrete statue of a middle finger and point it towards Latin America. Both a wall and the statue would be equally offensive and equally ineffective…”

Many Delta region residents and environmentalists feel similarly about the Delta tunnels.  

And Metropolitan’s new go it alone financing plan makes the tunnels even more divisive than ever, because it will open up a new hostile front in California’s water wars between the urban serving State Water Project and the agricultural serving Central Valley Project.  MWD’s Jeff Kightlinger acknowledged this when answering concerned questions from his board members:

"it puts the two projects in competition instead of in partnership and how to sync their operations. Now you would have CVP people saying we need to maximize south Delta, we need to politicize that issue as much as we can, and that’s not appropriate because we’re the one who made the investment to do the more environmentally friendly investment. How we would work that with the state and federal project at odds with each other, trying to work these out in the state and federal legislatures is challenging..."
This is an accurate assessment of the additional conflict, except that many disagree with him that the tunnels are an environmentally friendly investment.   

Metropolitan’s new financial plan would make a bad project even worse.  Will Met’s board be able to resist the political pressure to take a rushed vote on this ill-advised strategy?  Sounds like we will find out next month.

It Is Strange To Be Accused of Bias By WaterFix Supporters for Following The Information in Their Own Documents and Applications for Project Approval

The response from opponents to the benefit-cost report is both predictable and a little bit strange.

Someone from the Department of Water Resources criticizes it for not using the "declining baseline" of water exports, and the pro-tunnels group "Californians for Water Security" says that we "fail to acknowledge economic losses of future water cutbacks without project."

This criticism stems from the fact that I followed their documents.  In essence, they are saying that a good analysis would make stuff up that is completely inconsistent with the official documents the WaterFix has created to support its applications for regulatory approval.

It seems that in the opinion of Californians for Water Security, and Department of Water Resources' spokespeople, an unbiased benefit-cost analysis would make the following unsupportable and speculative assumptions.

  • Future environmental restrictions on water exports can only affect the no-tunnel scenario, and that the WaterFix is somehow immune.
  • If future environmental restrictions were to reduce water exports, it would have no environmental benefit to society, only costs to water exporters.    
Both of these are false, and addressed in the report.  Any reasonable argument to support the first assumption went away with the change in the proposal from BDCP to WaterFix.  Water operations could decreae in the future in response to environmental conditions and regulations with and without the WaterFix.  The benefit-cost analysis correctly focuses on the incremental change in water supply with and without the tunnels.  There is no reason to believe the incremental supply with and without would be any different even if future regulations are tighter.

The second assumption that these potential environmental regulations would only have costs but not offsetting environmental benefits is simply false.       

But this is a silly debate with media spokespeople.  There is only one reasonable response for project proponents.  Follow your own guidelines and repeated promises, and complete your own benefit-cost analysis of the WaterFix that is integrated and consistent with the environmental documents.

In fact, one of the goals of doing this report is to put some pressure on the state and project proponents to put their benefit-cost analysis on the table like they promised to do last year.  Then we could compare the assumptions, the points of consistency and inconsistency with the environmental documents, and have a real informed discussion about the merits of the WaterFix proposal.

Benefit-Cost Analysis of the WaterFix

Earlier today, the Center released a benefit-cost analysis of the California Water Fix.  Last year, state officials said they would release their own benefit-cost analysis in August 2015, but it is now a year later and nothing has been forthcoming.  In this analysis, I would describe the "optimistic" scenario as my best estimate of what I think DWR's benefit-cost analysis would look - based on previous work done by their consultants for the tunnels when they were part of the BDCP.  The "base" scenario reflects what I believe are more realistic values, and in both cases the WaterFix has benefits that are far less than costs.

Since the benefit-cost ratio for the optimistic scenario is so low, it did not seem necessary to consider a pessimistic scenario which would consider possibilities of higher costs or that the tunnels created greater environmental damage than predicted in the proponents' documents.  While 23 cents of benefit per dollar of cost is bad, the reality could be even worse.
