by Matt Williams –
Let me once again start by saying that the opinions and perspectives presented here in this article are those of the author and are not the opinions and perspectives of the Water Advisory Committee (WAC).
Unlike the meetings before it, meeting number 7 of the WAC contained virtually no discussion of how the WAC should conduct its activities, votes and recommendations. If the WAC is following Tuckman’s stages of group development, also known as the “Forming-Storming-Norming-Performing” model of group development, then the WAC appears to have successfully completed the Storming stage and will hereafter be concentrating on Norming and Performing.
Speaking of Perfoming, when the meeting started I thought we were about to have a rousing and interesting Public Comment segment, because Michael Harrington and his lovely daughter arrived in Council Chambers just as the meeting was about to start. Unfortunately, Michael disappeared just as mysteriously as he had arrived, and the Public Comment cupboard was bare when Chair Elaine Roberts-Musser polled the Chambers for any public commenters who might want to let the WAC members know what was on their mind. Michael’s take on the WAC’s progress to date would have been refreshing.
Presentation of the Night – Bartle Wells’ view of where Davis’ Water Rates may be going
Doug Dove from Bartle Wells gave the WAC an update on his progress since his original Water Rates presentation in WAC meeting #5 on February 23rd (as reported here in the Vanguard) and Kelly Salt’s sharing of her legal expert opinion on the effect of the Palmdale vs. Palmdale case on the WAC’s Water rate discussions (as reported here in the Vanguard). Doug first covered a March 2012 Water Rate Survey of 19 cities and/or water authorities near Davis. The Average Monthly Water Bill from those 19 was $40.52, with Davis coming in at an even $34.00 (7th lowest of the 19); however, WAC members peppered Doug with follow-up information requests designed to put the information into perspective. Bill Kopper pointed out that a snapshot of rates in the past 12 months is useful, but is also much less important than what those 19 cities are anticipating in terms of future rates. Bill asked Doug to recontact the cities and ask them for what their rates are going to be for each year through 2017. Doug agreed to do so and get back to the WAC with the results. Matt Williams pointed out that average monthly bill amounts only tells a portion of the story, and that it is important to know what the monthly water consumption in each of the 19 cases, so that the WAC can get a better sense of how much of a factor Water Conservation is in the selected cities/water districts. Doug agreed to gather that information as well.
Doug then transitioned into a discussion of possible Revenue Requirements that possible Davis Rates may need to generate. This portion of Doug’s presentation proved problematic . . . not so much because of the substance of what he presented, but rather because of the political implications of some of his choices of words. My personal sense was that Doug’s “mistake” was an innocent one, but it did raise some hackles. Specifically he presented three Revenue Requirement scenarios, which he labeled “Worst Case” and “Best Case” and “No Project.” That in itself was not a problem. The problem came when he explained how he had gotten the assumptions for the best and worst cases, both of which were based on possible scenarios of proceeding with the Surface Water Project as proposed. Given the recent Council Check In where the WAC is charged with “voting and/or making recommendations about the surface water project and any potential alternatives” Mark Siegler summed up the feeling of some of the WAC members present (but not all of the WAC members present) that he felt he was getting a bit of a sales pitch for the Surface water Project, and he didn’t feel that that was appropriate. Doug responded that he was simply trying to put the Lower Cost Assumptions of the best case and the Higher Cost Assumptions of the worst case into a context that WAC members would easily grasp. He agreed to couch all future scenarios in more generic terms.
Doug concluded by making his recommendation that the original list of nine rate structure possibilities be pared down to three. This narrowing of the rate structure possibilities was spelled out clearly in the Scope Of Work document, but some of the WAC members felt that simply listing the eliminated rate structure possibilities was not informative enough, so Doug agreed to provide the WAC with a short explanation of why each of the six eliminated structures was eliminated. The eliminated structures were:
- 100% Fixed Rates – the same monthly flat fee for every water user regardless of the amount of water consumed. This structure may no longer be legal in California because it contains no water conservation incentive.
- 100% Variable Rates – no monthly flat fee, only a $ per gallon amount times the actual number of gallons consumed each month. This is the rate structure Sue Greenwald has been advocating for here in the Vanguard. Per Bartle Wells, the Pros of such a rate structure are that the charges are proportional to actual usage , and there is a strong conservation incentive. The Cons are that it produces unstable revenues and will result in a fiscal deficit if the amount of actual conservation exceeds the amount of projected conservation.
- Uniform Block Rates – the simplest blend of 100% Fixed and 100% Variable Rates, with a flat monthly fee plus a $ per gallon amount times the actual number of gallons consumed each month.
- Declining Block Rates – a blend of a flat monthly fee plus a tiered $ per gallon where the price per gallon decreases for higher levels of water use. The clear problem with this kind of structure is that it makes high use of water less expensive, which only works in a situation where there is plentiful water.
- Seasonal Rates – charges different rates during the different seasons of the year. Mark Siegler wasn’t clear why this option should be eliminated and Doug is going to get bck to the WAC with an explanation of why it should be.
- Drought Rates – usually these rates kick in when the water district declares a drought and requests cutbacks.
The three structures that Doug suggested the WAC proceed with further analysis on were as follows. The descriptions of the Inclining Tier Rates and Water Budget Based Rates are taken from an article written by Kelly Salt, the legal expert on Proposition 218 who spoke to the WAC in our last meeting.
- Inclining Tier Rates (aka Inclining Block Rates) – a blend of a flat monthly fee plus a tiered $ per gallon where the price per gallon increases for higher levels of water use. This is the structure Davis currently has, with two tiers. Inclining Tier Rates are characterized by an increasing unit price of water; the more water that is consumed by a customer, the more expensive the water gets. Increasing block rate structures provide a stronger “price signal” (financial disincentive to high water use) than flat rates do, particularly if there is a steep incline to the height of the tiers. One inherent problem with inclining-block rates, however, is the inherent revenue volatility they can create. If the width and height of the tiers are not properly designed, appreciable revenue may depend on sales from the higher tiers, which are the most susceptible to changes in consumption behavior because of the correlation between outdoor usage and weather conditions.
- Incentive Discount Rates – this alternative has been actively advocated for by Michael Bartolic. Sacramento uses a form of this structure, whereby if the customer achieves certain thresholds of lower water usage than a predetermined target, a percentage discount is applied to the bill. The more a customer conserves the lower their bill goes.
- Water Budget Based Rates – Water budgets are a type of inclining-block rate with individualized allocation of water based on specific customer characteristics. Characteristics for setting the indoor portion of the water allocations may include the number of household members. Characteristics for setting the outdoor portion of the water allocations typically include a set amount of water to support an agreed upon amount of landscaped land area. The implementation of water budget rates has been made possible by the advent of computerized utility billing systems that can incorporate specific customer-level information into a billing calculation. Water budget rates address both conservation and equity goals by giving an effective price signal through the designation of efficient water use for individual accounts. Water budgets also have the added benefit of being well-suited for drought condition pricing. By making simple modifications to water allocations, a water agency can effectively and equitably target excessive consumption with higher rates. This is in contrast with typical drought condition rates, whereby a water agency asks for uniform percent reductions by all customers, even those who have historically been frugal with water use.
Pending the explanation of why he eliminated the six structures, the next step will be for Doug to develop actual cost schedule scenarios for each of the three selected rate structures. The WAC was very clear that they wanted to see a sensitivity analysis for each structure that showed a number of different scenarios of cost from lower cost assumptions to higher cost assumptions . . . irrespective of what project the WAC recommends to City Council.
Stay tuned . . . the WAC is your government very much in action. Its fun. It’s lively. Most of all it is very informative. If you want to know more about water, don’t miss it.
Watched last night and have a few comments. Seemed only a few WAC members commented until there was a round robin which surprised me.
. Was very impressed with the ones who questioned the consultant, but he who sonewhat clueless as to the purpose of the committee. How much and who is paying him for his work? Until the questioning turned things around, it seemed to be a description of the surface water project as proposed and I thought I was on the moon!
Thx Matt. The subcommittee work will be interesting. I especially liked the 9 risks of not proceeding which one member stated. Very thoughtful approach.
SODA, the whole discussion of the risks list read by WAC member David Purkey will be the topic of a second WAC article on Sunday or Monday. I felt it deserved its own article.
[b]For anyone who is interested, the WAC will be having another meeting tomorrow starting at 9:00 AM in the Council Chambers.[/b]
The meeting topic is:
[b][i]2011 Summary of Evaluated Alternatives to the Davis Woodland Water Supply Project – with emphasis on the Deep Aquifer – Background/Discussion[/i][/b]
Rob Beggs from Brown and Caldwell, who has studied the Deep Aquifer will be the presenter. His presentation should be informed and informative. I look forward to hearing him. Come join us if you want to know more about the Deep Aquifer and how it figures in the future of the water supply in Davis.

Doug Dove, is the representative/spokeperson of Bartle & Wells, the consulting firm hired to do the rate study. I did not see Mr. Dove’s choice of words as problematic at all. If folks were paying attention, it has already been revealed in previous meetings and last night that the rate structure model created specifically for Davis will be GENERIC in nature. Whatever alternatives are chosen for consideration are plugged into the rate structure model to determine resultant rates needed to generate a particular amount of revenue required for the particular project chosen. As a place holder, Mr. Dove chose three possible alternatives that there were hard numbers for – the surface water project; the surface water project paid for with some existing funds already collected from the wastewater side; and doing nothing. IMO, it was inappropriate to read anything more into that than these were mere placeholders to use as examples, and it was my understanding of the reasons for those particular choices.
The WAC and every member on it is well aware we are exploring various alternatives to the surface water project that will be very much included as part of the rate study. In fact, and I’m sure Matt will get to the rest of the WAC discussion, the various alternatives and how to analyze them were debated at great length in the second half of the meeting. Mr. Dove’s comments must be taken in context; Mr. Dove is not well versed in the controversies surrounding the proposed surface water project and how to frame everything he says to be politically correct; so Mr. Dove would have no idea that his chosen placeholders would be attacked as somehow emblematic of an attempt to foster one choice over another, when I very much doubt that was the case.

I guess I am surprised the presenter wasn’t given more info on the history of how the WAC was formed and the objective of its work. It just seemed the questions of the committee illustrated that his report wasn’t as generic ad they had hoped.

I’m not quite sure I understand your point. How was the presenter’s report not “generic”, as you put it? All the presenter did was use three examples to illustrate the rate principles: surface water project; surface water project partially paid for by the wastewater side; no project. The three choices were merely place holders that the consultant had dollar figures for. It will be up to the WAC to let the consultant know what alternatives other than the surface water project as proposed we would like the consultant to plug into the rate structure model – but WAC members have not made that decision yet… stay tuned!
