I refer to it as "Best of Intentions Ordinance" in that we had intended to have this ordinance in place effective for this summer's water I consumption. However, we also intended to ensure that the general public was fully knowledgeable as to the ordinance prior to it becoming effective. The item was first considered in April and then resubmitted in June. The Council desired to see a public I hearing set which was then established for July 23rd. Unfortunately, although the hearing notice was published, the item did not appear in the printed agenda and tabling to this agenda was I necessary. I am not aware of any persons who came to City Hall on July 23rd to provide testimony on the proposed rate change. Recommendation I As this is a public hearing, a formal "opening" and "closing" of the hearing should occur. If the Council agrees with overall II purposes being presented, staff should be instructed to include the resolution establishing the excess usage charge on an upcoming agenda. It should be noted that the "excess usage" portion of the I rate adjustment would not become effective until 1991. This action will ensure that we can publish the effective rate schedule changes both this fall and next spring.

Water rates have not I increased for the past five years. No change is being proposed to the sewer fee schedule. The "excess water usage" charge is being recommended to discourage unnecessary sprinkling during the summer months. The proposed charging method would be based on each I individual's water const}mption during the winter quarter. Once usage exceeded 30% of that base, the excess water charge would then apply. An analysis of the effects of these charges to average II customer groups is included at the rear of the Finance Department report. Generally, senior citizens would see a reduction in their bills. Two and three person families would see a 5%-10% increase in their total bill due to the rate increase and, if they watered 11 in a similar fashion io last year, they would be paying an additional $10 to $20 per year for that excess water usage. [Note: The above figures are based on a current average of approximately I $200 per year in annual Oilling,] ;� .; The proposed rate modifications were primarily a result of meetings 11 between staff and our auditors, Deloitte-Touche. It is their belief that the City should not continue to operate its utility system in a deficit position. The deficit has been decreasing over the years, but still remains relatively high. IAs noted earlier Cliff Hoffman and Dan Mayleben will be present to discuss the audit report. Hopefully we can use the question I portion of that item to respond to Council questions regarding the proposed utility rate modifications. Recognizing that it has been five years since a rate adjustment was sought and that the rate adjustment is relatively minor, the City Council should strongly I I/ Mayor and City Council 1 June 25, 1990 Page 2 consider making the change as recommended. This statement is made recognizing the fact that the Council has placed a priority on not increasing general property taxes. If we are to do such, we must make sure that other revenues do keep pace with our growing community. Accordingly, this office would recommend that the City Council I authorize the City Attorney to draft a resolution which incorporates the proposed rate changes. • I I 1 f f 1 I 1 1 CITY OF CHANHASSEN WATER AND SEWER UTILITY i 1 I .

Three of the wells have pumping capacity of 1 ,000 gallons per minute each. The fourth well is located in the Minnetonka Intermediate School , and has an estimated pumping capacity of 150 gallons per minute. Water quality tests are done monthly for bacteria -and turbidity. The most recent water analysis testing of these wells was done in 1984 (figure 1 test results attached) . A new analysis is planned for mid-1990. I These wells are located at: 1 . Well #1 - W 76th Street (abandoned) 2. Well #2 - W 77th Street at South Shore Drive 3. Well #3 - Galpin Blvd south of Lake Lucy -Road 4. Well #4 - Lake Susan park shelter B. The city currently is in the process of drilling well No. 5 near the site of well No. 2 at an estimated construction cost of $155,000. This well is anticipated to be on-line by July, 1990. Well No. 6 has also been authorized by the City Council at an estimated construction cost of $400,000. C. There are 3 water towers with a total storage capacity of 1 3,800,000 gallons, of which 1 ,800,000 gallons is considered "useable" . Locations and total capacity are: 1 . Cty Rd 17 at Lk Lucy Road - 3.5 million gallons (2.0 million gallons below service pressure zone) 2. Murray Hill Road - 200,000 gallons 3. W 76th Street - 100,000 gallons D. There are currently 67 miles of sanitary sewer and force I main in the city of Chanhassen and 67 miles of watermain. The city maintains 22 wastewater lift stations. E. Roughly 8 square miles or 1/3 of the city is currently serviced by city sanitary sewer and water. F. The city is presently in the process of installing a I $200,000 + supervisory control and data acquisition (SCADA) telemetry system to provide more efficient and cost effective management of the utility system and emergency response. 11 -1- rL I pct,y-f5/ i- ii n'1 1 iuy.Linkr1it`r 1 f/ s FIGURE 1 r I61713th AVE.

GEOGRAPHIC DESCRIPTION A. Districts/Billing Cycles: I To allow for a reasonably level flow of work volumes associated with the utility billing process (i.e. , meter reading, statement preparation, payment processing) and provide a reasonably consistent cash flow, the city has been split into 3 separate districts. Billing a different district each month for the previous quarter, provides a smooth cyclical flow of work levels and revenues. The districts and geographic area are depicted on Figure. 2 and are described as follows: 1 . District *1 South of Lotus Lake, East of Kerber Boulevard, the Downtown area, Lake Riley area, and Near Mountain. 2. District *2 East of Galpin Boulevard, West of Kerber Boulevard, the Industrial Park and Shadowmere Development. 3. District *3 I West of Galpin Boulevard, North of Lyman Boulevard, South of Highway 7, Lake Susan Hills Development and Pheasant Hill area. B.

If my interpretation of this plan is correct, I hope you'll give a little deeper thought to more sides of the issue. I'm away a good deal of the winter. Therefore, my winter water r ll consumption is quite a bit less than in the summer. Normal [ summer bathing and washing activities - without any lawn sprinkling t at all-could throw me into the excess usage category. I could ill leave the water running while I'm out of town in the winter, but I don't think this is what you have in mind. E What about a family where children are away at school in winter? 11 Augmentation of household size on a seasonal basis for whatever f reason could create an "excess usage" situation if the city uses a variable base level. Again, no lawn sprinkling is involved. 1 r A family of 5 uses far more of the earth's resources than my family of 2 and my family of 2 uses more than a household of 1. Tying II conservation to family/household size (which a variable excess rate does by legitimizing a larger base rate for some) is a very E i II sticky issue and one I don't think you want to get into. i II Please understand I'm not quarreling with the idea of paying more f for excess water usage. Graduated or accelerated rates are accept- able to me and to promote conservation. What I'm taking issue II with is the idea that "excess" will vary from household to house- hold. NSP charges more for increasedelectrical use in the summer, but the point at which electricity consumed starts to cost more II is the same for every household or subscriber. Likewise, the base level of water use should be the same for all residences in the city and not vary from household to household. ` Does the city even have the computer system that can vary the ) I base level from household to household and year to year? Please think this proposed plan through very carefully. II Sincerely, f r II II"Pane S. Partridge • II 11 3 I . CITY OF 1 of CHANHASSEN 690 COULTER DRIVE • P.O. BOX 147• CHANHASSEN, MINNESOTA 55317 1 (612) 937-1900 • FAX (612) 937-5739 II August 6, 1990 1 Ms. Jane S. Partridge 6280 Hummingbird Road 1 Excelsior, MN 55331 Dear Ms. Partridge: I Thank you for your letter of July 9, 1990. Your letter has been forwarded to the Chanhassen City Council and will be a part of their consideration prior to adopting an excess usage water charge Iordinance. Let me start by responding to your last questions first. II Specifically, the city does have a computer system that currently keeps track of the base level of every resident's water consumption. This system has been operational for the past ten years. The reason individual usage is maintained is to more 1 accurately establish sanitary sewer charges for each of our customers. Specifically, the winter quarter (the quarter encompassing the month of January) has been found to most I accurately represent sewer discharge volumes on a yearly basis. To even our workload for meter readers/utility clerk personnel, the city has adopted a series system of quarterly billings. Accordingly, a portion of our community may be billed for the 1 period of November, December and January; whereas another portion of the community may be billed for the months December, January and February. Again, the computer system maintains not only the series 1 records, but the utility usage during those time frames. The winter quarter reasonably assures that the sewer charge, during the remainder of the year, is set during a time frame when typically no I lawn sprinkling, car washing, swimming pool filling, etc. is occurring. The reason the city places an emphasis on the winter quarter usage II is because it costs approximately twice as much to clean dirty water as it does to produce clean water. To charge a customer a sewer charge for water used during the summer would most likely be Ian overcharge as most of that consumption would be attributable to sprinkling, car washing, etc. The current system attempts to be as reasonable as possible for a majority of our utility customers. IIYou are correct in noting that not all customers have the same II II Ms. Jane S. Partridge August 6, 1990 Page 2 I habits/usage. Customers taking winter time vacations or having students in school during the winter quarter do have a winter quarter usae which probably is not typical of their actual usage on a yearly basis. Accordingly, their sanitary sewer charge for the year has been inappropriately set too low. However, I believe that the number of customers falling into this category is small in comparison to the total customer base. Ironically, the excess water use charge could in fact have the results of more equitably recouping total costs for those people who do have inordinately low winter quarter usage. While it is true that the city could establish a fixed minimum charge for all users, the variable system does appear to have greater equity for all customers. Fortunately, I will not vote on this issue. As stated earlier, the City Council does have your letter and this response. If I understand you correctly, you are not opposed to the excess usage charge, but believe that such should be set based on a certain minimum. Again, I disagree, but respect your opinion. Sincerely, '<(2 DaLeZ) Don Ashworth City Manager DA:k 1 1 1 I 1 I City Council Meeting - June 25, 1990 II Resolution #90-71: Councilman Workman moved, Councilman Johnson seconded to accept the feasibility study for the upgrading of County Road 17 from Trunk Highway 5 south to Lake Drive West and to call the public hearing for July 23, II1990. All voted in favor and the motion carried unanimously. CONSIDER ACCELERATED WATER RATE SCHEDULE FOR WATER UTILITY. I/1( Don Ashworth: Jean Meuwissen and Tom Chaffee are both here. I thought that they did an excellent job in putting together the report you have in front of II you there. It's more information regarding our utility system than you probably ever wanted to know but it does show a number of interesting items and I think that the primary one is that the City Council started talking about oh, 3-4 I months ago and maybe even going into this past year trying to find some mechanism to ensure that as a community we were making a statement that we wanted to see our natural resources, more specifically our water, preserved and II that any of the existing water schedules where you would see a reduction in water rates with the more water you consummed is actually counter productive to any environmental type of efforts. I think we'll probably be tracking in some new area. here. I do not know of any city in the State of Minnesota and this II was again part of the thing that Deloitte had brought up, that has taken this type of a step to put into place a rate structure that will in fact establish a penalty for excess water useage during the summer months. As a part of that, I you've got a great deal of flexibility. What do you pick out as the quantifiers that you're going to use. What we used was establishing, and it's a good thing we have computers today, but the computer will go in and analyze each individual account. Determine your. . .water- consumption which is basically your winter II consumption and will then establish a rate that produces a quantity. We will provide 30% above that during the summer months but anything .in excess of that 30% useage over your normal winter quarter would go at this higher accelerated II schedule. What has been used for, in-house purposes is a 50 cents surcharge on that additional useage. In that process we also reduce the minimums to insure that senior citizens, those people who were are the very low end of the schedule II would not have, right now you have certain disadvantages. Disincentives. So for example if you're hit into the elderly area and you can use 10 or 20,000 gallons at a minimum charge, what advantage is there for you to use less water. So our rationale was let's cut that down to as minimal a minimum as we can and II in fact provide some type of an incentive again for those seniors who do not use that much water. There is a general rate increase. The general rate increase is, if you take into account that there has not been a rate increase during the I past 5 years, is actually literally nothing in terms of the overall affects. With the surcharge, with the rate increase, I think we're still looking and we could go since I wrote the cover report and as mine's still on here, you're II looking at a 5% to 10% increase in their total bill. This would be for general rates. And an average family looking at potentially $10.00 to $20.00 increase if they maintain the same water useage rates that they did this past summer. So for Tom's analysis, he had the computer go in. Calculate what the low quarter II would have been from a year ago. Then provide the 30%. Then analyze what you actually used this past summer and what your actual surcharge would have been. Those statistics are what is used to produce the averages on page 8. ICouncilman Johnson: We should have done Tom and Don's houses and seen what our actuals would have been. II 46 I City Council Meeting - June 25, 1990 Mayor Chmiel: I said look at my bill for an example. 11 Don Ashworth: One is? Jean Meuwissen: One is your house. bon Ashworth: My house or Oon's house? Jean Meuwissen: You. Ashworth. Tom Chaffee: We were going to use the term normal too. . .but normalcy. Councilman Johnson: Not if you had Don's included on there. How much was Don's increase then? I Tom Chaffee: In order to compensate for the variances in the schedule we put in the fact that the City Manager's bill would increase by 230%. I Councilman Johnson: Well one of his daughters is in college now so the water useagc and phone useage is way down. Jean Meuwissen: Except for the summer when they're home. Don Ashworth: I'm a 3 person household? 1 Jean Meuwissen: Yes. Mayor Chmiel: Your's looks pretty much like mine. I think mine comes to about 1 90 something per month. Or per 3 months. Excuse me. Ton Chaffee: These are annual figures here. Don Ashworth: Recognize that when I give my 5% to 10%, I am using the total billing that goes out from the City. So we're not proposing any increases in the sewer rates and so when I'm making those types of comparisons, I'm saying that the average is $200.00 per year for sewer and water and so the increase in water rate in comparison to your total bill is the 5; to 10%. Councilman Workman: Are you saying that no other community in the State has done this? Don Ashworth: I'm not aware of any that has an incentive or disincentive program or penalty to. Councilman Johnson: It's an incentive to conserve. 1 Mayor Chmiel: Basically to save water. Don Ashworth: Most rate schedules still go on the older philosophy that the more you use, the less you'd get some type of a cost breakdown. Councilman Workman: NSP works like that. I think it's a good idea. I'd be waiting to hear some of the flack on it but it certainly is a good idea. I just have one question and that is how it relates to water consumption by industry I 47 11 City Council Meeting - June 25, 1990 • that , like Rosemount uses I think an awful lot of water down there for cooling, IIetc. . How is that going to impact them? Are they going to go through the roof? Mayor Chmiel: Are many of these people aware as to how it 's going to affect IItheir particular balance? Cary Warren: We're taking their winter quarter use and giving them that plus 30% so unless they outrageously change some process or something. ICouncilman Johnson: I think that they chose to. . . I Councilman Workman: But 30% of $100,000.00 water bill or whatever is a lot of bill. Councilman Johnson: Rosemount uses a lot of water but in their final IIdevelopment they chose to go with a recirculating system versus a once through non-contact for their cooling which is what would have really increased in the summer. I don't know if they've switched back on that . 1 Gary Warren: We haven't seen that . The Rosemount useage was pretty up there the last quarter. IIJean Meuwissen: 16 million. II Gary Warren: So maybe they haven't got that system going yet but there's a l of Ovate,-. lot Cc::ncilman Workman: We're talking about a large financial impact . IIDon ,,:shuorth: Out Councilman Workman, just so you understand. See you calculate the winter quarter. Say during the summer months, the first 130% of I that would be calculated at the lower rate. So you would not pay at the higher- rate until you get to that. Councilman Workman: But it 's going to impact them proportionally like an IIindividual. Don Ashworth: Until you brought out the question I really hadn't thought about I it but I think you might have just the opposite situation. If you had a large industrial type of user and you give them 30% for their winter quarter, you can . almost assuredly, they would not pay any additional for watering during the II . summer just because of the size of that account. Probably the watering would be very minor in comparison. Gary Warren: They have such a large base that they're working from. IIDon Ashworth: Tom, did I make a mis-statement? I Tom Chaffee: I wanted to point out that in the process of our study, and I did point out that there were 92 unique connections here if you will here in the City that sprinkler meters, homeowners associations, etc. and we didn't I specifically address to the 130% item because the example of a sprinkler meter, ill you don't run in it in the winter. So typically then, depending upon the position that the Council wanted to take, all of their useage for the second and II 48 City Council Meeting - June 25, 1990 • fourth quarter could be considered excessive useage. You look at it purely from a conservationist standpoint . Or again going back to using our sophisticated computers for analyzing, we can come up with a median or a means from which to derive their 130; basis to work from for the excess useage. Councilman Workman: Well we've got that same bridge to cross for the storm water utility somewhat don't we? Who to assess, the individual or the homeowner's association. Councilman Johnson: We have homeowner's associations that have water meters? 1 Mayor Chmiel: Sure. Councilman Johnson: So for their sprinkling it's all. . . Councilman Workman: All the outdoor spigots are homeowner association controlled and so I would then therefore have no storm water utility problem would I? Councilman Johnson: No. ' Councilman Workman: But that 's the thing. Councilman Johnson: Yeah, because there there would be. Now Rosemount would I have an average winter useage and if they've got also a watering system that's on a separate meter, which if they don't they should have, I would say that their watering would be part of the 30% above their normal flow. The homeowners association, I have no idea how to handle that because there won't be any flow in the winter. Jean Meuwisen: Rosemount would not be. . . Councilman Johnson: Yeah, but you would take their industrial use and allow them 30% for their sprinklers. So you add them to because they're both at physically the same location. You could add them together. Tom Chaffee: You add the consumption together in order to arrive at your 130% though. Councilman Johnson: Right . You could do that with the homeowner's association except you have to add everybody's water use together throughout the neighborhood or somehow or another. Gary Warren: Well even like in the storm water utility district we're saying 1 that there's an opportunity for somebody to appeal on a rate. There are some exceptions that maybe need to be specifically looked at and calculated but the idea is to get at giving some credit for the fact that you've got a base useage which everybody needs and then you've got people who can get excessive and I think that 's the policy that we're looking at. Councilman Johnson: There are a lot of people out there, I don't know how many 1 in this town, but in various other suburbs that use drinking water to cool their buildings with. They run it through a chilling system. One time through and then dump it down the storm sewer. It 's something that is wasting our ground , 49 I 11 . City. Council Meeting - June 25, 1990 water considerably. I think there's a shopping center right over there that does a couple million gallons a day for just cooling the shopping center. ' Because ground water is so cheap, it encourages that and this is the proper step and is an example for the whole State to take. The legislature ought to be looking at something like this in requiring this so that they discourage that type of abuse of ground water. • ' Councilman Workman: Well I would move to authorize the City Attorney to draft a resolution which incorporates the proposed rate changes. Councilman Johnson: What kind of public notice should we do on this? ' Mayor Chmiel: That 's one of the things my concern is. Making sure that everybody is aware as to what we're proposing and having some kind of a public notice for this. ' Councilman Workman: We're going to need to have something drafted. Mayor Chmiel : And I'd like to see some comparisons rather than just one or two ' or three to look at it from residential as well as commercial and industrial. Tom Chaffee: Would you like to see those now? Mayor Chmiel: No. I'd like to have them ready at that time. Don Ashworth: So you're saying probably the second meeting in July and we have a larger notice in the newspaper. Councilman Johnson: Did I second that yet? ' Mayor Chmiel: Yes. Cary Warren: No. Councilman Workman: Did you? ' Councilman Johnson: No I didn't. Jim Chaffee: Gary did. 1 Mayor Chmiel: Okay, there's a motion on the floor with a second. Councilman Workman moved, Councilman Johnson seconded to authorize the City Attorney to draft a resolution which incorporates the proposed rate changes. All voted in favor and the motion carried unanimously. 1 CONSIDER PURCHASE OF BUILDING INSPECTION VEHICLE. Don Ashworth: We did get a very excellent bid from earlier this evening. That process did save us, I would say $4,000.00 to $5,000.00 over what we originally looked to. I sincerely believe that we could look to again that same type of dollar savings if we literally went back out again. That coupled with the fact that we have both the Escort and the Lynx that are really on their last legs. 50
