TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL FROM: George Murdoch, Acting Municipal Operations Department Director - (949) 644- 3011, gmurdoch @newportbeachca.gov PREPARED BY: Rachell Wilfert PHONE: 949 - 644 -3010 TITLE: Recycled Water Rate Establishment ABSTRACT: The City of Newport Beach provides non - potable (recycled) water to five customers for the purposes of irrigating parks, schools, center medians and golf courses. Recycled water is purchased from the Orange County Water District through the Green Acres Project. The current charge for recycled water includes fixed fees and a commodity rate set at 80% of the potable water rate. The Municipal Operations Department retained the consulting services of HF &H Consultants, LLC (HF &H) to prepare a recycled water rate study. The study analyzed the cost of service and made recommendations regarding the rate and structure in compliance with State law. The study concluded that a rate adjustment is recommended as well as a different structure moving away from tracking the potable water rate. RECOMMENDATION: a) Review the results and proposed recommendations of the recycled water rate study; b) Direct staff to send rate notices to customers in compliance with Proposition 218 and Resolution No. 2009 -58; and c) Set the date of August 12, 2014 for tabulation of protests and public hearing of proposed rates pending results of protests. FUNDING REQUIREMENTS: There are no funding requirements required for this action. Should Council approve of the recommendations, a recycled water rate and structure may be established unless written protests against the proposed rate are presented by a majority of owners of the parcels subject 611 to the rate. DISCUSSION: Background: Recycled water is treated wastewater provided by the Orange County Water District (OCWD) under the Green Acres Project (GAP). GAP is a water conservation effort that provides recycled water for landscape irrigation at parks, schools, center medians, and golf courses. The City currently has five recycled water customers totaling 14 connections. The customers include Big Canyon and Newport Beach Country Club golf courses; East Bluff School, Our Lady Queen of Angels School, and the City which uses recycled water for irrigation of some roadway medians and parks. In 1991, the City entered into an agreement with OCWD for the distribution and sale of GAP water. The agreement stipulates that recycled water rates may not exceed 80% of the potable water rate. The agreement term is for 25 years with five 5 -year automatic extensions, with an estimated ending term year of 2041. Following the 1991 agreement, the City entered into "End User Agreements" with customers in 1996 for a 10 -year term. These agreements, now expired, included provisions that OCWD and the City would provide funding to modify golf courses and construct pump stations to facilitate the use of recycled water. In 2011, the City and the Big Canyon Country Club entered into a new agreement that provided for the delivery and sale of recycled water, and a pump station license agreement. All past and current agreements set the recycled commodity rate at 80% of the potable water rate. In 1995, the potable water rate was $1.94 per Hundred Cubic Foot (HCF). Eighty percent of that rate was $1.53 /HCF. Currently the potable water rate is $3.08 /HCF and the recycled rate is $2.47 /HCF. In the last nineteen years the potable water rates have increased significantly mostly due to increased import water costs from Northern California and Colorado River. Recycled water rates have tracked these rate increases. Our customers and staff recognized the need to set the recycled rate to the true cost to provide this service. Staff conducted a Request for Proposal (RFP) in 2013 to study the rate and selected HF &H. Recycled Water Rate Study: HF &H collected data from staff including past, present and estimated expenditures and revenue requirements; the 2011 cost allocation plan prepared by MGT America, Inc.; and the 2013 Fee Schedule adopted by City Council on October 22, 2013. Staff provided pump station maintenance costs and manpower to operate and maintain the system. HF &H has prepared the attached memorandum for review and comment. As a result of this analysis, staff is recommending an adoption of a five -year rate with a 2% annual adjustment to reflect the anticipated future increases in costs associated with operations and maintenance of the system. Additionally, in the event OCWD increases the cost of recycled water by more than 2 %, staff recommends that the rate structure include an adjustment to reflect the actual commodity cost charged by OCWD. Staff presented these results to the Finance Committee on April 29, 2014. The Committee approved the recommendation to move the item to the City Council for discussion. Below is a summary of the analysis and recommendations. 612 The current rates for recycled water are divided into two components: Fixed charge - a monthly service charge based on size of connection. Commodity charge - a monthly charge for all customers based on 80% of the potable water rates. Under the new rate structure the recycled commodity costs will not be linked to potable water rates. The proposed methodology for the new rate structure has three components: Fixed charge - a monthly service charge based on size of connection. Commodity charge - a monthly charge for all customers based on the actual commodity cost charged by OCWD Pump Station charge - a monthly charge for users of recycled water pump stations based on the cost to operate, maintain, and replace the stations. The total revenue requirement for fiscal year 2014 -15 is estimated to be $279,366 and consists of: Fixed costs o Meter Reading ($1,514) o Meter Replacement ($2,543) o Overhead - Other City Departments ($12,208) o Administration - MOD Staff Time ($25,433) o Other agency fees - Health, County, etc. ($2,034) Commodity cost o The cost to purchase recycled water from OCWD ($173,417) or $0.86 /HCF Pump Station costs o Inspections ($7,021) o Maintenance - Production, SCADA, Corrective ($13,109) o Rehab & Replacement ($42,087) Proposed Five Year Rate Establishment Monthly Service Charge Current Year 1 Year 2 Year 3 Year 4 Year 5 5/8" or 3/4" $13.82 $18.91 $19.29 $19.68 $20.07 $20.47 1" $23.03 $31.53 $32.16 $32.80 $33.46 $34.13 1 W, $46.06 $63.05 $64.32 $65.60 $66.91 $68.25 2" $73.70 $100.88 $102.90 $104.95 $107.05 $109.19 3" $138.18 $189.15 $192.94 $196.80 $200.73 $204.75 4" $230.30 $315.25 $321.56 $327.99 $334.55 $341.24 6" $460.61 $630.50 $643.11 $655.98 $669.10 $682.48 8" $736.98 $1,008.81 $1,028.99 $1,049.57 $1,070.56 $1,091.97 Commodity Charge Per HCF $2.46 $0.855 $0.872 $0.890 $0.907 $0.926 613 Pump Station Charge Per HCF none $0.361 $0.368 $0.375 $0.383 $0.391 Under the proposed rate structure, recycled water users will see a reduction in their bill. Even accounting for a two percent annual increase beginning in the second year of the new structure, the updated rates provide a significant savings for the City's recycled water users, while still allowing the City to maintain infrastructure to provide recycled water service. The City invested Water Enterprise funding to construct the pump stations, service connections, backflow devices, swivel ells, and piping. City and OCWD contributed funding to golf courses for modifications to accept the recycled water. Staff feels the revenue generated above the cost of service since 1995 has reimbursed the water fund for these expenditures.

There will be a 45 -day public notice period. Following the public notice period, written protests will be tabulated at the August 12, 2014 Council meeting. City Council may then conduct a public hearing on the proposed rate and proceed with rate establishment unless written protests against the proposed rate are presented by a majority of owners of the parcels subject to the rate. ENVIRONMENTAL REVIEW: Staff recommends the City Council find this action is not subject to the California Environmental Quality Act ( "CEQA ") pursuant to Sections 15060(c)(2) (the activity will not result in a direct or reasonably foreseeable indirect physical change in the environment) and 15060(c)(3) (the activity is not a project as defined in Section 15378) of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no potential for resulting in physical change to the environment, directly or indirectly. NOTICING: The agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at which the City Council considers the item). 614 ATTACHMENTS: Description Attachment A - HF &H Recycled Water Technical Memorandum 615 ,HF H CONSULTANTS, LLC 201 North Civic Drive, Suite 230 Walnut Creek, California 94596 Telephone: 925 /977 -6950 Fax: 925/977 -6955 www.hfh- consultants.com ATTACHMENT A Managing Tomorrow's Resources Today TECHNICAL MEMORANDUM To: George Murdoch, City of Newport Beach From: John Farnkopf, Sima Mostafaei, HF &H Consultants Subject: Recycled Water Rate Update Date: May 30, 2014 Robert D. Hilton, CMC John W. Farnkopf, PE Laith B. Ezzet, CMC Richard J. Simonson, CMC Marva M. Sheehan, CPA Robert C. Hilton, CMC In preparing this recycled water rate update, expenses and revenues were projected through FY 2018 -19. Based on these projections, revenue increases were derived to meet the funding requirements. The recycled water rate structure was also redesigned to better align the revenue with actual costs. The following findings and recommendations were made. I. FINDINGS AND RECOMMENDATIONS 1. Key Assumptions. Rates were set to generate revenue sufficient to fund the City's recycled water systems operations and maintenance expense, the cost of purchasing recycled water from Orange County Water District (OCWD), and capital replacement expense related to pump stations and meters. 2. Rate Design. The City's current recycled water customers pay the sum of two charges: a monthly fixed charge that is based on the size of the connection, and a commodity charge based on metered water use during the monthly period. The rate charged is based on 80% of the potable water rate. We recommend unlinking the recycled water rate from the potable water rate and aligning the recycled fixed and commodity charges with the fixed costs and the cost of purchased water from OCWD, respectively. In addition to the fixed and commodity charges, pump station users will be charged a pump station charge based on the cost to operate and maintain the stations and convey recycled water. 3. Projected Rates. The rate projections are shown in Figure 1 -1. 616 ,HF H CONSULTANTS LLC Managing Tomorrow's Resources Today MEMORANDUM Page 2 of 7 Figure 1 -1.

During the projection period, the City's operating expenses are projected to increase gradually at about 1.73% per year, based on the five -year historical average of general inflation for the Los Angeles area. • Purchased Water -This cost category for FY 13 -14 was based on the actual water purchases in FY 12 -13 multiplied by the cost of purchased water from OCWD of $360 per acre foot. During the projection period, the City's purchased water costs are projected to increase gradually at about 1.88% per year, based on the five -year historical average of OCWD purchased water charges per acre foot. • Pump Station Operating and Maintenance - This cost category for FY 13 -14 was based on the actual cost of inspections, scheduled and corrective maintenance, source changeovers and pump station rehabilitation and maintenance as provided by the city. During the projection period, the City's pump station operating and maintenance costs are expected to increase gradually at about 1.73% per year, based on the five -year historical average of general inflation for the Los Angeles area. • Depreciation - This cost category includes replacement costs for pump station facilities and water meters. The annual pump station facility replacement cost was based on $600,000 in construction costs, amortized over 40 years. The annual meter replacement cost was based on the American Water Works Association's standard cost of $259 per meter per year, amortized over 15 years. During the projection period, the City's pump station facility replacement costs are held constant at $15,000 per year, while the meter replacement costs are projected to increase gradually at about 1.73% per year, based on the five -year historical average of inflation for the Los Angeles area. III. RATE DESIGN Current Rate The City currently has five recycled water customers totaling 14 connections. These customers pay the sum of two charges every month for water service: a basic service charge based on the size of the service connection plus a commodity charge based on metered water use during the billing period. In 1991, the City entered into an agreement with OCWD for the distribution and sale of recycled water. The agreement stipulated that the recycled water rate may not exceed 80% of the potable water rate. It is the City's current practice to charge customers 80% of the potable water rate based on that agreement. M. ,HF H CONSULTANTS LLC Managing Tomorrow's Resources Today MEMORANDUM Page 4 of 7 Proposed Rate Structure Under the new rate structure, the recycled water rates will no longer be linked to 80% of the potable water rates. The proposed rate structure is based on the FY 2014 -15 revenue requirement, and categorizes the expenses into three categories: fixed costs, variable costs and pump station - related costs. Fixed costs are considered fixed because they do not vary based on flow, and include the annual cost of meter reading and replacement, as well as administrative and overhead. Variable costs vary because they are based on the amount of water purchased, and therefore, are solely comprised of the annual cost of purchased water from OCWD. Pump station - related costs are comprised of inspections, maintenance, and rehabilitation & replacement that are directly related to the pump stations. Figure 3 -1 presents the breakdown of the FY 2014 -15 revenue requirement by cost category: Figure 3-1. FY 2014 -15 Revenue Requirement by Cost Category FY2014 -15 Ixed Costs Administration $25,433 Overhead $12,208 Meter Reading $1,514 Meter replacement $2,543 Other agency fees $2,035 otal Fixed Costs $43,732 ariable Costs Purchased Water $173,417 >tal Variable Costs $173,417 xmp Station Costs Inspections $7,021 Maintenance $13,109 Rehab & Replacement $42,087 >tal Pump Station Costs $62,218 Total Revenue Requirement $279,366 In order to determine the monthly charge by size of connection, we first converted the number of active meters to equivalent meter units (EMU) as shown in Figure 3 -2. The EMU multiplier by meter size is the same multipliers used to determine the fixed charge by meter size for potable water rates. The monthly charge for an EMU of 1.00 is derived by dividing the total 619 —`E Managing Tomorrow's Resources Today MEMORANDUM Page 5 of 7 fixed costs of $43,732 by the total number of EMUS or 192.70. This quotient was then divided by 12 to convert from an annual charge of $226.94 to a monthly charge of $18.91. The service charges were then graduated using the EMU multipliers, the effect of which is to increase the service charges for the larger services. Note the total annual revenue from fixed charges in Figure 3 -2 is equal to the total fixed costs presented in Figure 3 -1. Figure 3 -2. Calculation of Proposed Monthly Fixed Charges The commodity and pump station charges were derived using the FY 2012 -13 monthly meter readings in HCF for all customers, and FY 2012 -13 monthly meter readings for pump station customers in HCF, respectively. Figure 3 -3 presents the derivation of the proposed commodity and pump station charges for FY 2014 -15: Figure 3-3.
