Agenda Item #4.F DATE: March 20, 2017 TO: Honorable M and Members of the City Council through City Manager FROM: D St. E — Director, Public Works and Utilities Department SUBJECT: Discussion and Direction Regarding the 2017 Water and Sewer Utilities Rate Study RECOMMENDATION It is recommended that the City Council Discuss and Provide Direction Regarding the 2017 Water and Sewer Utility Rate Study. BACKGROUND On November 14, 2016 and February 13, 2017, the City Council held workshops to discuss the utilities rate study. Topics discussed included the current Capital Improvement Plan (CIP) and cash flow analysis that establishes future revenue targets, issues affecting rate design and revenue stability, and customer impacts. A rate proposal, referred to as Option 1 herein, was presented based on a "full CIP" scenario. The Council expressed concerns about significant rate increases and their impacts on particular classes of customers. To address this, a reduced CIP scenario was used in developing the proposed rates for two new rate options, referred to as Options 2 and 3. The purpose of the proposed action is to review the three rate options and finalize selection of the water and sewer utilities rate structure for the next five years beginning on July 1, 2017. To facilitate this goal, the report provides an analysis of impacts to various customer classes and benchmarking to other agencies. Once the desired rate alternative is selected, the rate study can be finalized and the public hearing for the Prop 218 process can be scheduled where the new rates can be considered for adoption with passage of a new rate resolution. The existing rates were adopted by Resolution Nos. 2011 -165 and 2011 -166 N.C.S. on December 5, 2011. These rates included an automatic pass through for both Consumer Price Index (CPI) inflationary changes and increases in the wholesale price of water charged by the Sonoma County Water Agency (SCWA). By law, the City is required to prepare a new rate study and adopt new rates every five years if it wishes to rely on automatic cost adjustments. Therefore, the new rates will need to be adopted before the existing rates, last adjusted on July 1, 2016, can be adjusted again. DISCUSSION The major elements of the rate development process have proceeded with the completion of the following key steps: • Finalization of the cash flow projections for water and sewer enterprise funds through fiscal year 2026/27 using full and reduced CIP scenarios. (Attachment 1) • Design of a rate structure sufficient to meet projected expenses taking into consideration direction provided at the November and February workshops. Three alternative rate structures have been developed for the Council's consideration. (Attachment 2) • Evaluation of proposed rate changes on key customer categories and bench marking to other agencies within our region. (Attachment 3) The cash flow projections indicate a need for rate increases for both the water and sewer enterprise funds. In the case of water, increased revenue is needed to offset losses in revenue due to water conservation during the recent drought, and for the City's participation in the emerging groundwater sustainability agency and the groundwater study. For both enterprise funds, the need to support the proposed CIP, even without most of the recycled water expansion projects, and the new pavement maintenance fee, will require an increase in revenues. On the wastewater side projected increases in maintenance and capital replacement costs at the wastewater treatment plant, along with the fiscal impact of the proposed bio- methane to compressed natural gas conversion program, are taken into account. The cash flow projections include the following assumptions for future -year expenses and revenues: • Operating Costs are generally escalated at the projected Consumer Price Index plus 1.5 %. • Pass - through of wholesale water rate increases from the Sonoma County WaterAgency for a total assumed inflation rate of 3.5% and the CPI. • Low to Moderate growth of customer base per City of Petaluma General Plan. • Enterprise funds reserve target is equal to three months operating expenses plus the average year's CIP expenses and in the case of Sewer an additional 3.5 Million is added in for rate stabilization. • Minor water demand "bounce back" after drought. • New debt issuance with new debt payments for water and for refinancing the 2011 wastewater bonds in sewer. • Draw down of sewer reserves to targeted levels by building reliable upgrades to the treatment plant and downtown sewers. For water, limited use of debt until new rates are phased in and to offset losses in revenue from the past few years of water conservation. Attachment 1 includes the detailed tables that summarize the CIP assumptions and the cash flow analysis that was used to develop the new rate options contained herein. The following figures illustrate the cash flow projections for the reduced CIP scenarios for both utility funds that were used in developing rate options 2 and 3: 2 $35 $30 2 $25 M $20 (D 0 C: 0 CL $16 is $10 $6 $0 City of Petaluma Water Projected Revenues & Expenses, Reduced CIP 2016117 2017/18 2018/19 2019120 2020M 2021122 2022123 2023124 2024125 2025/26 2026127 Excludes grant and debt-funded capital Improvements, but Includes projected new debt service on debt-financed projects.

Rate proposals were developed based on the parameters discussed at the November and February Council workshops, namely: • Shift the percentage of fixed revenue from less than 20% to a more stable target of 28 to 30% in the water fund, and from around 25% to 38 to 40% in the sewer fund. • Utilize the industry standard American Water Works Association (AWWA) Meter Capacity Ratio tables for establishing rates for non - residential customers. • Establish a new multi- family unit (MFU) fixed water rate, similar to that used in sewer rates, based on the single- family unit rate multiplied by a demand factor of 0.6 to account for lower average usage. Adjust the MFU sewer demand factor, currently at 0.87, to 0.85 based on metered winter use. • Introduce a fixed monthly Account and Metering Charge for all accounts. • For single- family unit (SFU) water customers, reduce the breakpoints in the water commodity charges for Tier 1 and 2 from eight to four hundred cubic foot units (one HCF equals 748 gallons). Changes in breakpoints allows the Tier 1 rate to remain the same as the existing rate for the next five years. • Other aspects of the rate design are similar to those used in previous rate studies and rate resolutions. Three rate options were developed to meet the following conditions and are summarized for residential and 2 -inch commercial meter categories in the following tables. For the sake of clarity, rates are shown assuming no CPI or SCWA wholesale rate increases: Option 1: Rates presented at February workshop for full CIP scenario and targeting 30 %, and 40% fixed revenue for water and sewer funds, respectively. Fixed charge does not include any water or sewer use. Option 2 (recommended): Rates based on reduced CIP scenario and targeting 28 %, and 38% fixed revenue for water and sewer funds, respectively. Fixed charge does not include any consumptive water or sewer use. Option 3 Water only_ Similar to Option 2 except SFU fixed charge includes the first HCF unit of water usage. Commodity charges for SFU's would start with the second HCF of water usage in a month. The detailed rate schedules for Options 1 and 2 are included in Attachment 2. The rate schedule for Option 3 is identical to Option 2 except the SFU fixed and tiered commodity charges are as shown in the following table: M sw a) .}+ m w L 4- O to E E v / J m Q UL M + M M 00 m m m LL �' _ o w N1 � 00 cyi t tin t4i�, ttii tMii M 0 � M `-� m «`ti m m oho rn H cu O c F4 r tr} 4j)- v tip V)- 00 00 7 M c-i h M to m ll7 cr Q) O N 6 14 0�0 v } ciI�Ti tip O M ro �, � U O d e ' H vhi a E � 00 °' m m o m m z o o� � 14 ,�, tM/� 44 Kam /} tM/} N H M M CO h 1-I 00 H' N LL .Q I d ca � �- tlN/0 � t/� V1. in t} i C v H p U NI cn 0 0 N tO _ m an d Ln m Z -- ih, �w Q n c *' u m ul h o N cn rj ON N a) G1 Lu O ct m to N 00 m H v Q v t/} t!} tf} V _ V).

By lowering revenue requirements and by reducing the targeted fixed revenue slightly in Option 2, the fixed rates shifted downward to lessen the impact on customers with low water use when compared to Option 1. While the percentage increases for multi- family water, customers appear high, it is related to the existing, very favorable rate structure for this customer class. Actual increases for MFU customers are lower than with SFU customers over the long run. Low -use customers would continue to benefit from the Option 2 rate design due to the still low fixed rate revenue recovery strategy and the revision to the tiered commodity charges. Option 3, whereas SFU customers would only be charged a commodity charge for any use over one HCF. is believed to be more difficult to communicate and will require re- programming of the City's billing system to accommodate. While Option 3 would benefit the very low SFU water customer, the financial impact to most residential customers is similar for both Options 2 and 3 because they are based on a common computation of fixed and commodity charges. In Option 3, one HCF unit of water is included in the fixed rate charge for the SFU customers. To accomplish this, the wholesale cost of that HCF was added to the fixed charge calculated under Option 2 to address the concern that another user group might otherwise be subsidizing the rates for this low - use category. In addition, the tiered rates were adjusted accordingly to offset the projected loss of revenue caused by not charging the Tier I rate for the first HCF used by SFU customers. A downside to Option 3 is that a low -use customer using less than one HCF per month would be paying the wholesale rate for a full HCF unit as part of their fixed charge whether they use it all or not. A more thorough analysis, assuming projected CPI and SCWA rate pass- throughs, was conducted on Option 2 rates to predict impacts on key customer categories as summarized in the following tables and detailed in Attachment 3: G Summary of Water Rate Impact - Option 2 (Z) Customer Description Monthly Use (HCF) Current JUIV 2017 Increase July 2021 5 Increase July 2021 July 2017 SFU - Low User: 25th Percentile 3 $17.95 $20.13 $2.18 $31.17 $13.22 SFU - Median User 6 $28.51 $31.55 $3.04 $44.99 $16.48 SFU - High User: 90th Percentile 13 $56.55 $61.95 $5.40 $81.66 $25.11 MFU, per dwelling unit (1) 4 $17.10 $21.54 $4.44 $30.44 $13.34 Small Business 10 $46.49 $49.07 $2.58 $66.97 $20.48 Medium Business 25 $108.50 $113.15 $4.65 $150.76 $42.26 Large Industry 5,000 $19,720 $19,994 $274.00 $24,889 $5,169 Notes: 1) Analysis based on a 20 unit apartment with a 2-inch meter using 80 HCF per month. 2) Assumes projected CPI and 5CWA Wholesale Rate pass thru.

A comparison of the new debt requirement and average annual rate increase is summarized in the following table for the three rate options: Option 1 Options 2 or 3 Annual Rate Increase 5% 3.5% Borrowing $17 M $11.8 M SEWER FUND Borrowing $13 M $0 M It is recommended that the Council direct staff to complete the rate study in accordance with the information and rate design presented herein for Option 2 or as otherwise directed. Option 2 seems to best balance the direction of the Council to be sensitive to impacts on the low water user customers while supporting an ample CIP, albeit reduced from what was originally presented in earlier workshops, and while moving the rate structure to a more stable platform with higher percentages of fixed revenue than in the current rate structure. When directed by Council, the rate study will be completed in accordance with the Proposition 218 process. Public noticing of the proposed rates would be mailed 45 days or more prior to a public hearing scheduled to allow for the protest voting procedure. It is recommended that the Proposition 218 hearing and adoption of new rate resolution be scheduled for the Council meeting of May 15. The new rates would apply to water and sewer services billed after July 1, 2017. A 30 -day notice for implementation of the new rates would not be required this year due to the Prop 218 notice but would be sent in subsequent year in accordance with State law. The new rate resolutions would address updated language and necessary changes to the existing rate resolution, including: Setting of the recycled water rate at 50% of the "other customer class" potable water commodity charge, resulting in a FY 17/18 rate of $1.98 per HCF compared to $1.88 per HCF currently. This would allow recycled water rates, unchanged for 5 years, to be automatically adjusted annually as potable water commodity charges increase over time. Establishing an "all -in" rate for water haulers based on the total cost of service. While the use in this category is very small at less than 1 % of the total, water haulers currently only pay the commodity charge and do not pay a fixed charge, other than a meter rental fee. For equity with other users, the "all -in water hauler rate, estimated to be about $5.50 per HCF, would include their fair share of fixed costs and capacity (i.e. impact) fees. The final computation of this rate will be included in the rate study. While considered, it is not recommended to pursue higher out -of- service area rates for customers residing outside of City limits. Limitation of Proposition 26 appears to restrict the City's ability to do so. FINANCIAL IMPACTS The proposed water and sewer rate structures, discussed herein as Options 1, 2 and 3, will increase revenues above what would be generated by the existing rate structure to meet cash needs, which include all existing programs and the CIP scenarios. The following table shows the increase in cumulative revenue over the 5 -year rate period ending on June 30, 2021 for Options 1, 2 and 3 compared to the existing rate structure: Increase in Cumulative Revenue Through FY 21122 Increased CIP spending Options Option 1 Option 2 or 3 WATER 17,123,000 13,209,000 SEWER 14,144,000 5,237,000 Total 31,267,000 18,446,000 CIP funding will increase over current levels to make necessary infrastructure enhancements with all three rate options.
