A---T iY'-ij &, -14 -IU To"" \tro>,,--lKj Hi, Mike and Martha I've been thinking about the two following questions for a while and want to give you a preview ahead of tonight's study session. Both involve having the AWAC group specify 'parameters' upon which the study is to be based (this is my version of it). Part of which I'm pondering is whether both of these parameters are policy decisions rather than something that the AWAC group should decide - but beyond that issue are the following questions: 1. Re: How much conservation does the City want? This question seems very broad and unspecified yet picking a number could have major policy implications. So, first of all, what does it mean: reduce annual water usage by X gallons? or Y percent...of what? Etc. And, beyond that, I think there is a general feeling in the community that we waste water, especially during warm weather - but we waste it for a variety of reasons. We may be used to treating water as free and plentiful. We may not have a way of telling how much water we use. We may have landscaping that wasn't planned to be frugal in its use of water but would be expensive to change. We may have inefficient irrigation systems. We may feel it's our right to use as much water as we want if we're willing to pay the price. How in that complex web of issues is a citizens committee supposed to take a position, especially without knowing all the ramifications of picking a particular number? Are we, in effect, going to outlaw lawns? Are we going to provide support to the citizens who really want to conserve (in terms of ways of measuring their water use, for example)? Are we going to change the laws regarding grey water use (or lobby the State to do so)? . 2. What amount of redundancy do we want? Here I'm concerned about two things. First, this should not become a situation in which TAP advocates and opponents feel compelled to take positions because of their preconceived beliefs, i.e. make sure to set the number high or low enough to achieve their goals with respect to TAP. Second, to me it seems as though this is a question that should be asked_after_the overall system has been analyzed. For example, don't we first determine how much water the city will need in coming years and then look at how we deal with uncertainty, variability, and contingencies - all of which will have options and associated costs. At that point there will be difficult trade-offs, not just costwise but operationally, for example, if we use wastewater plant effluent how are we going to control for contamination and won't effluent volume decrease with conservation and with main supply levels, etc? And ultimately we will have an overall cost projection going forward about what it will take to keep a secure and sufficient supply for the city over time so that we avoid digging ourselves a financial hole. This is a big sustainability point. I can see as I try to think this out, that it makes the process much easier to manage if you specify up front some of the things you ultimately want to be able to vary - and maybe that's what our planning people are trying to do - but taking a position on conservation or redundancy has big implications and how do we know that we're not preempting the Council from being able to make key decisions by the assumptions the AWAC is being asked to make now? And, going back to the start: what does X% conservation actually mean? And the same for redundancy? For example, if we want Y% redundancy, is that of current winter water use adjusted for projected population growth? Or is the answer that we want to be able to make it through three years of drought, a major fire in the watershed, and a significant amount of vegetable gardening taking place within the City limits? Hopefully the above gives you an idea of why I'm concerned or unclear about these aspects of the Water Plan process. John '- " ., .2. CD 2.)> 00 < :!: CD Q) < ~ _. c.
