Memo, Sue Iverson May 13, 2008 2. Utility Rate Study, Water and Sanitary Sewer prepared by Ehiers & Associates, Inc ~ ~~HILLS MEMORANDUM DATE: May 13, 2008 TO: Honorable Mayor and City Council FROM: Sue Iverson, Finance Directo~ SUBJECT: 2008 Utility Rate Study Background/Discussiou: As previously discussed, the enterprise funds have excess expenditures over revenues in the 2008 budget. 1 met with our financial consultants from Ehlers & Associates, Inc. in November to review the Financial Management Plan and to discuss conducting a Utility Rate Study. (This was to be part of last year's Financial Management Plan, but was postponed in order to get accurate numbers and accurately assess what our major problem areas were.) At our December work session, Mark Ruff and Jonathan North from Ehlers & Associates, Inc. were present to discuss policy direction to be used in the rate study. It was also noted that part of this study would be used for the TCAAP resource plan and could be charged back to the developer as it was part of the PDA agreement. In January 2008, the Council authorized Ehlers & Associate, Inc. to conduct the rate study. Elizabeth Diaz and Jonathan North of Ehlers will be presenting the Water and Sewer portion of this study at the May work session. The Storm Water portion will be presented at a later date, as it is not completed at this time. Attached you will find the Water and Sanitary Sewer Study prepared by Ehlers & Associates, Inc. They have presented three options and a tiered rate system as requested by the Council. One of the problems with the existing rate structure is the impact of the Senior Citizen Discount. The tiered rate system attempts to address this problem with minimal impact. At a preliminary look, the water rates need a 6% increase, the sewer rates need a 6% increase to the base charge and an 18% increase to the usage charge. The current rate structure has not accounted for the increases in the Metropolitan Council Environmental Services charges which have increased 5 - 9% each of the last four years. We have also factored in the 1&1 needs for this fund. STAFF RECOMMENDATION: Staff's recommendation would be to adopt Option II for both the water and sewer rates. This option gives the City more protection in low usage or "wet" years, as 41 % of the revenue is captured in the base charge and 59% is captured in the usage charges. It also provides incentive for water conservation. Memo City Council 2008 Utility Rate Study 2 When looking at this option for sewer rates it is also possible to phase in the increase to senior citizens over time. . . , City of Arden Hills Water & Sanitary Sewer Utility Rate Study May 19, 2008 Prepared By: City Staff and EHLERS LEADERS IN PUBLIC FINANCE I. Introduction The City of Arden Hills requested that Ehlers & Associates assist staff in preparing financial projections for the water and sanitary sewer system utilities. The purpose of the rate study is to ensure that: I. Rates are sufficient to pay for the ongoing operations and capital improvements, and to maintain adequate cash balances; and, 2. The rate structure distributes the costs of operating the system across utility users consistent with the policy objectives of the Council. Background The City has maintained a comprehensive long-range capital improvement program for many years focusing upon replacement of existing infrastructure. The City's has paid for cash for improvements. As a result, the City has relatively low cash balances, but no debt obligations. Municipal utility funds are considered "enterprise funds," meaning they are intended to be operated as a private enterprise in which the fee revenue pays for all expenses. For purposes of this study, we refer to each segregated utility as its own fund. This base model incorporates expected capital improvements for the existing population of the City. The draft capital improvement plans for water and sewer are located in Appendices D and E, respectively, and include water utility repair costs in conjunction with pavement management projects, water tower repainting, lift station improvements and a SCADA system. The report demonstrates potential rate tiering options. A second model to be completed as additional infoTIllation becomes available, will incorporate additional grow1h, capital and operating costs for the Twin Cities Army Ammunition Plant site development. Assumptiolls Following is a chart that summarizes the significant assumptions in the rate study.

Rate Structure Current billing structure is a fixed Currently residents are billed year- rate 01'$2.86 per 1,000 gallons for round based on water consumption at usage over the 10,000 gallons per $3.24 per 1,000 gallons over a base quarter base, and a base meter usage of 15,000 gallons. The base charge 01'$29.22. Seniors are billed meter charge is $67.83 per quarter. at $2.93 per 1,000 gallons with no Seniors are billed at a base rate of base meter charge. Additionally, $45.20 with no additional usage there is a residential stand by charge charge. of $6.60 per quarter for residential accounts. Two of the proposed rate structures on Appendix F move to a three- tiered rate svstem for all users. Development The City currently does not charge The City currently does not charge a Fees area fees for development. The City sewer area fee for development. currently charges a water connection fee of $80 per connection. 3 Water Utility Water Fees The City of Arden Hills currently purchases water from the City of Roseville. There are three primary components to the City's water utility revenues: J.,,feler Charges are a fixed quarterly fee based on the size of the meter in the home or business. Most residential meters are at $29.22 per quarter and the fee includes a base usage of I 0,000 gallons per quarter. The meter charge is established to recover certain fixed expenses, such as the billing system, that the City must incur for a customer regardless of the amount of water consumed. This meter charge raises approximately $296,000 per year. Additionally, there is a stand by charge of $6.60 per quarter for residential accounts which raises approximately $158,500 per year. These two charges pay for utility staff, operating costs and a general fund administration charge. Usage Fees are based on the metered use of water. Currently the billing structure is a fixed rate of $2.86 per 1 ,000 gallons for usage over the base usage of 1 0,000 gallons per quarter. The usage fees pay for the cost of purchasing water from the City of Roseville. In 2007, usage fees generated approximately 69% of total water revenues. Below is a chart which demonstrates the breakdown of types of users in the water utility. Type of Water Utility User by Number 100% 60% 40% 2007 Of the single family residential customers, approximately 60% of the usage was billed at the higher usage rate, or for usages over 10,000 gallons per quarter. The typical single family home uses 20,000 to 25,000 gallons per quarter on average and the average senior residence uses approximately 16,000 gallons per quarter. The following graph depicts the distribution of all residential water users by amount of water used in one year and incl udes all residential users. r 4 Gallons Used per Year by Number of Households 350 300 250 '" "C "0 "" 200 ~ '" ~ 0 :I: 150.

These fees typically are intended to cover the cost of expanding the water utility system to the users who will benefit from it. The City currently does not charge a WAC fee. We would recommend that the City establish hook up charges for in- fill development and for business expansion. We would also recommend that the City study the costs of extending city utilities to the TCAAP area and detemline and adopt a TCAAP WAC fee. This fee would be applicable to the TCAAP area only and would be designed to recover the cost or a portion of the cost to extend services to that area, according to City Council policy direction. The City does, however charge a water connection fee of $80 and is designed to cover the cost of the connection from the property to the water main. Tiered Rale Syslem Beginning in 2009, we are recommending that the City consider revisiting its usage fee structure. With a multi tiered rate system, the typical resident will pay morc pcr gallon for water used for sprinkling than they will for water used in daily activities. Most metro area suburbs have adopted a tiered rate system for the following reasons: J 5 1. To promote conservation effor1s. 2. To allocate costs appropriately to those who are generating them. Cities construct water systems to meet the capacity of peak watering days in the heat of the summer. In Arden Hills, the peak demand in the summer is approximately 2.4 times the average daily winter demand. A tiered rate system charges more per gallon for peak use, thereby allocating the cost of "oversizing" the system for peak days to the peak users. Residential Water and Sewer Rate Options The three rate options were designed in order to provide sufficient resources for projected operating expenses and capital costs and to build cash balances where necessary. The following graph shows the historic trend in cash balances for the Water Utility and the Sewer Utility. Historic Trend in Cash Balances S1,800.0001' 'W.

As is apparent. the Water Fund has been operating at a deficit during the years of 2004-2006, resulting in a total operating deficit of $493,800 from 2004 to 2006. Capital costs during that time totaled $1,022,300. Water operating revenues have not kept pace with expenses.

It is also apparent that operating revenues have not kept pace with expenses and capital outlays. This fund operated at a loss from 2002 to 2006. The combined operating loss from this time period was $672,800 and the total capital expenses during that time equaled $696,500.

Proposed Residential Water Rates The City cUITently spends approximately $655,000 in fixed costs such as salaries, contractual and depreciation and an additional $960,000 in purchasing water from the City of Roseville. For all the rate tier options for both water and sewer, we explored changes to the residential rates and held the commercial rates relatively constant in order to avoid discouraging development or redevelopment from occurring. 7 While commercial entities pay the same rate for water usage as a residence, they pay higher fixed monthly meter and stand by charges, in essence paying a higher rate per gallon for water used. Existing Residential Rate Structure-Rate Option I: This rate structure would apply to single family and multi-family residential and senior residents. If the existing rate structure is not modified, the quarterly meter charge would increase by $1.75 to $30.97 per quarter for a residential home in 2009, $32.83 in 2010, $34.80 in 201 I, and $36.89 in 2012, or a 6.0% increase per year. Commercial and industrial users would pay an increase of 6.0% based on the meter size. The City has seen water consumption increase with the popularity of lawn sprinkler systems, and staff has emphasized the increasing importance of water conservation and the need to charge those who necessitate over sizing of the system for peak usage. The Minnesota DNR is putting pressure on cities to implement conservation measures, and is reluctant to issue permits to cities for new wells if conservation measures are not in place. A pricing structure that makes heavy lawn watering more expensive is one way to encourage conservation. The current rate structure does not provide incentives for water conservation Rate structure Options II and 1ll do provide an incentive for conserving water resources as is shown on Appendix F. Residential Rate Option II This tier option would keep the existing base usage of 10,000 gallons, but institute two tiers above it. The first tier above the base usage would be for usage up to 35,000 gallons, or the next 25,000 gallons of usage, and would be charged at $2.73 per thousand gallons. The second tier above the base usage would be for all usage over 35,000 gallons and would be charged at $4.78 per thousand gallons. This tier option produces $1,040,000 in usage revenues, or roughly equal to the amount of purchased water charges paid to the City of Roseville. The meter charge increases slightly for a residential user from the present amount of $29.22 to $32 and for a senior residence from no current charge to $17. The fixed charges, (meter charge and stand by charge) generates $505,800 in revenues, or equal to the amount of fixed charges such as salaries, contractual and general fund admin charge. Total revenues then, equal approximately $1,546,000. This option captures 41 % of the water usage in the base, 40% in the second tier and 19% in the top tier. The average residential user then has a usage charge which represents approximately 51 % of their water bill. The proportion becomes higher as the usage goes up and the rate per gallon becomes higher with greater usage, which provides an incentive to conserve water. The average residential user of 25,000 gallons per quarter pays $.0032 per gallon and a higher residential user of 50,000 gallons per quarter pays $.0071 per gallon. The low senior user (16,000 gallons) would pay $.0016 per gallon. l' 8 This rate tier option would provide an incentive for water conservation and would likely provide a buffer to the city for lower usages which would occur during wet weather summers because there is an even split between usage charges and fixed fees. The proposed rate for Option 11 is shown in greater detail on Appendix F. Residential Rate Option III This tier option shows a meter charge for all usage and the corresponding fixed meter charge decreases dramatically. A residential user meter charge decreases from $29.22 to $9 and the senior residence increases from no charge to $9. The first tier would include all usage to 15,000 gallons at $1.50 per thousand gallons. The second tier would be for the next 20,000 gallon usage or from 15,001 to 35,000 at $3.25 per thousand gallons. The third and final tier would be for usage over 35,001 gallons billed at $4.88 per thousand gallons. The revenues generated equal $311,900 in fixed charges and $1,285,700 in usage charges for a total of $1 ,597,600. Under this option, usage charges represent a higher percentage of the total bill than Option 11. The average residential user then has a usage charge which represents approximately 81 % of their water bill. The proportion becomes higher as the usage goes up and the rate per gallon becomes higher with greater usage, which provides an incentive to conserve water. The average residential user of 25,000 gallons per quarter pays $.0027 per gallon and a higher residential user of 50,000 gallons per quarter pays $.0070 per gallon. The low senior user (16,000 gallons) would pay $.0016 per gallon. This option captures 56% of the water usage in the first tier, 26% in the second tier and the remainder in the top tier. The proposed rate for Option III is shown in greater detail on Appendix F WAC Fees We are recommending that the City study the costs of extending water utility services to the TCAAP area and institute development fees in order to recoup costs of the improvement. Some cities in the metro area have made it a policy decision to recover a targeted percentage of construction costs through WAC and SAC charges. The remainder of the costs would be recovered through user charges. Cash Balallces Operating Reserve We recommend the water fund carry a m1l11mUm cash balance for operations of an amount equal to 50% of operating expenses excluding depreciation plus annual debt service. Cash balances are available to accommodate fluctuations in revenue depending on weather and higher than anticipated operating expenses. /, I 9 All of the three rate options above are designed to meet this operating reserve goal. Capifal Reserve The remaining cash balance should be held for 10ng-teTIl1 replacement of the system, which will not be able to be funded with grow1h. The model builds the ending cash balance over time. The recommended measure of a goal for the capital portion of cash reserves is the target working capital as outlined in the city's annual financial report. A graph below demonstrates the projected capital cash balance compared to actual working capital assets of the water enterprise fund: 2,000,000 1,800.000 1,600,000 1.400,000 1,200,000 1,000,000 800,000 600,000 400,000 200,000 o Water Fund Capital Cash Reserves "GlTarget working capital Ii iOActual working capital .1: o ~ ~ ~ ~ ~ v ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ 0,." f5 0,." 0,." 0,." f> 0,." f> 0,." f> 0,." 0,." 0,." f> f> f> f> I, 10 Sanitary Sewer Utility Sewer Fees The City of Arden Hills participates in the Metropolitan Council Environmental Services (MCES) sanitary sewer system. The City is responsible for the sewer collection system within the City limits and then pays MCES disposal fees for treatment. The MCES disposal fees have increased 5 - 9% each of the last four years. The rate study anticipates that future increases for these fees will be 5%, annually. The MCES disposal fees comprise 54% of the sewer utility's operating expenses based on the 2008 budget. Another 10% of expenditures represent depreciation, while only 36% of operating expenditures are within the City's control. From the graphs shown on page 6 and 7, it is readily apparent that Sewer Utility revenues have not kept pace with operating expenses and capital costs. The rate options outlined below are designed to reverse this trend and build cash balances. Sewer Rate Structure The current rate structure is $3.24 per 1,000 gallons of non winter sewer usage over water usage of ] 5,000 gallons. Seniors pay a base quarterly charger of $45.20 and other residents pay a base quarterly charge of $67.83. The minimum charge helps pay for the fixed costs of the system as outlined in the water utility description. Existing Residential Rate Structure-Rate Option I The projected usage rate increase under the existing rate structure for sanitary sewer is 18% per year for the next three years. It appears that the reason for the increase is that the pace of MCES rate increases has been higher than City user rate increases. It also appears that rate increases adopted in the past have not kept up with the cost of capital improvements. The proposed rates are shown in the chart below. Base charge Usage charge 6.00% 6.00% 6.00% 6.00% 6.00% 6.00% 6.00% 18.00% 18.00% 18.00% 6.00% 6.00% 6.00% 6.00% 2008 2009 2010 2011 2012 2013 2014 2015 45.20 47.91 50.79 53.83 57.06 60.49 64.12 67.96 67.83 71.90 76.21 80.79 85.63 90.77 96.22 101.99 Senior Non Senior Usage-over 15.000 gallons (per thousand gallons) 3.24 3.82 4.51 5.32 5.64 5.98 6.34 6.72 As mentioned above, the MCES charges are increasing at 5% per year. We are concemed about the long term cash balances of the sewer fund. I II The proposed rate for Option I is shown in greater detail on Appendix F. Residelltial Rate Option II As with Option II for Water, the sewer charges would be based on water usage and the first 10,000 gallons would be included in a proposed meter charge of $70.50 for residential and senior residential users. Usage over 10,000 gallons would be charged at $3.75 per thousand gallons. Commercial user would be charged $3 per thousand gallons. Given our concerns regarding the existing and future cash balances of this fund, rate increases were intentionally shifted from water to sewer charges by offsetting the faster pace of sewer charge increases for the average residential user and the senior user with a slower water charge increase. The utility user views their water and sewer bill in total and we attempted to control the overall increase in the combined bill by shifting the majority of the increases to the Sewer Fund. Option II provides $1,453,900 in total revenues. In some cases, a user would see a decrease in the water portion of their bill, but an increase in the sewer portion of the bill. The proposed rate for Option II is shown in greater detail on Appendix F. Residential Rate Optioll III Rate tier option 1II would impose a charge for all usage. The base charge would then be decreased from the current base charge of $67.83 for residential and $45.20 for seniors to $50 for residential and $25 for seniors. All usage would be charged at $3.50 per thousand gallons. Commercial users would be charged $3.50 per gallon. Option 1II provides $1,432,300 in total revenues. The proposed rate for Option 1II is shown in greater detail on Appendix F. Sanitary Sewer City Connection Fees The City currently has not instituted a SAC fee. We would recommend that the City study and determine the costs associated with the TCAAP area and adopt applicable rates. As with WAC fees, some cities have chosen to make it a policy decision to recover a targeted percentage of construction costs through SAC fees, which may be paid at the time the permit is pulled or the plat approved. There are differing levels of risk regarding the timing. Collecting WAC and SAC fees when the plat is approved insulates the City against market downturns and places the carrying costs on the developer. We are also recommending that the City adopt a SAC fee to future in-fill development and business expansion. Cash Balances Operating Reserve We recommend the sewer fund carry a minimum cash balance for operations of aJ) amount equal to 50% of operating expenses, excluding depreciation, plus annual debl 12 service. Cash balances are available to accommodate fluctuations in revenue depending on weather and higher than anticipated operating expenses. Capital Reserve The remaining cash balance should be held for long-term replacement of the system, which will not be able to be funded with groW1h. The recommended measure of a goal for the capital portion of cash reserves is the accumulated depreciation of assets as outlined in the city's annual financial report. The following graph demonstrates the projected capital cash balance related to the target working capital amount: Sewer Fund Capital Cash Reserves 1,600,000 1.400,000 1,200,000 1,000,000 800,000 600.000 400.000 200.000 .i....'..<............>\'/: ~~.~~0 ~ ~ ~ ~ w ~ '1) 1''),'>'),'>1'1'1'1'1'1''),'> ';CC:.()CCi t:"~'U,0'~"" . I. 13 Summary The City of Arden Hills has managed its utility funds well, and as a result has been able to pay for all improvements on a cash basis. However, doing so has caused a steady decrease in cash balances. The need to upgrade and expand the water utility system over the next several years will introduce new financial pressures along with the need to increase cash balances. The rate study indicates that water rate increases are necessary in 2009 (implemented at the end of 2008) to maintain cash balances and pay for capital improvements and debt. Steady and fairly significant rate increases will be needed for the sanitary sewer fund, beginning in 2009, to keep pace with the MCES disposal fees and to pay for City operating costs and capital improvements. While this analysis proposes the use of debt to allow for steady and predictable rate increases, it is not a debt plan. The City should review whether it has sufficient cash to pay for capital improvements prior to issuing debt. Debt options include interfimd borrowing and issue general obligation bonds. As with all other bonding decisions, the City's decision to issue debt for any given improvement will be based on many factors, including the City's cash balances, rating, and other fjnancing needs.
