Water Transmission FY 20 23/2024 Draft Budget and Rates This draft FY 2023/2024 Water Transmission Budget has been developed based on the prior 12-months of water deliveries of 41,847 Acre-Feet (AF). Due to the drought and the community’s water conservation measures, budgeted deliveries are 8.5% less than FY 2022/2023. The draft budget is shown in the table below:

F
Y 2023/2024 Draft Budget Financial Summary compared to FY 2022/2023 Adopted Budget: Factors affecting the rate increase:

Operations and Maintenance (O&M)
• 8.5% decrease in budgeted deliveries.
• 1% increase in water sales revenue
• FY 2023/2024 budgeted expenditures: $40.41 million. An increase of $1.73 million or 4.5%. • $640,000 in Use of Fund Balance.
• Budgeted expenditures increase is attributable to the tank recoat program, SCADA improvements, and large equipment purchases.
• Must have sufficient net operating revenues to meet 1.15x debt coverage bond covenant requirement. • Water Sales Revenue Shortfall:
o FY 2021/2022: $1 million; FY 2022/2023: estimated $4 million to $6 million below budget. • Actual Expenditures plus Encumbrances compared to Budgeted Expenditures tracked very closely in FY 2 021/2022 and are anticipated to align closely in FY 2022/2023 with the exception of several projects that experienced unforeseen delays: Cathodic Protection, Tank Maintenance Program, SCADA improvements. Unspent budget from these projects is rolled forward to subsequent budget years to avoid being included in the rate calculation more than once. The FY 2023/2024 budget shows increased costs for these projects over prior years.
• Budgeted projects have been thoroughly reviewed and edited, and represent the budgeted work that can reasonably occur in FY 2023/2024. Budgeted maintenance projects are a priority and cannot be deferred further.
• 10.70% rate increase compared to 18.97% increase in FY 2022/2023.

DRAFT

Sonoma Water iii Draft 2/28/2023
Biological Opinion
• 8.5% decrease in deliveries
• 3% increase in revenue
• 44% decrease in expenditures
• $3.50 million in Use of Fund Balance reduces rate increase from 266% to 9.94% • 9.94% rate increase compared to -75.35% increase in FY 2022/2023 when $7.5 million in Use of Fund Balance was budgeted.

Dry Creek Habitat Enhancement Phase 4 design activities have been completed. The U.S Army Corps anticipates construction of Phase 4 in the summer of 2023. Right-of-way activities are ongoing for all three phases. Sonoma Water has pending expenditure credits under review by the U.S. Army Corp. The credits may offset a portion of Sonoma Water’s 35% cost share for Phases 4, 5, and 6 construction costs. The draft budget includes the addition of design, right-of way, and construction for Dry Creek Habitat Enhancement Phase 4 inlet 13B, ongoing costs for Phases 5 and 6 design, right-of way, and construction and other required biological opinion activities.

Among other ongoing biological opinion activities, Sonoma Water staff are currently working on revisions in anticipation of recirculating the Draft EIR in 2023.

In FY23/24, a $150,000 match contribution has also been included for the Potter Valley Project Russian River Water Forum Grant application submitted to DWR under the 2022 Urban Community Drought Relief Grant Program. If the grant is awarded additional match would also be provided by the County of Sonoma, County of Mendocino, and the Sonoma Water Russian River Projects Fund.

Water Conservation
• 8.5% decrease in deliveries
• 0% increase in revenue
• 3% decrease in expenditures
• $418,000 in Use of Fund Balance. Reduces rate increase from 34.88% to 13.85%. o FY 2022/2023 Adopted Budget used $568,000 in Fund Balance to reduce the Water Conservation Rate Increase to 6.89%.
o Without the Use of Fund Balance in the FY 2022/2023 Adopted budget, the Water Conservation rate increase would have been 34.88%.
o Due to decreased deliveries, there is limited capacity to use Fund Balance in the FY 2023/2024 Adopted Budget.
• 13.85% rate increase compared to 6.89% increase in FY 2022/2023 when $568,000 in Use of Fund Balance was budgeted.

Programmatic Summary an d Effect on Rate Increase:

Sonoma Water and the Sonoma Marin Saving Water Partnership plan to continue work on drought related initiatives and corresponding outreach and education activities.

There was an expansion of programs (at the direction of the Water Contractors) to respond to the historical drought conditions after rates were set in FY21/22 and FY22/23. The costs of these programs were not captured in the previous years’ rates and the expenses we therefore paid for by fund balance. These programs included a $66,000 increase for Drought kits and prize giveaways, as well as $40,000 in printed drought outreach materials, $195,000 in advertising, and $28,000 in ad-design services (photography, videos, and graphic design).

This year we are also proposing to apply for and if awarded administer a Department of Water Resources (DWR) grant through the Urban Community Drought Relief Grant Program. Pursuing this grant does increase the proposed rate in the subfund for FY23/24 by approximately 8.5% due to upfront match costs, which includes not only programmatic match, but also match from grant administration staff expenses that disproportionately fall DRAFT

Sonoma Water iv Draft 2/28/2023
in FY23/24 (due to required agreements needed with the Partners) that are only 55 percent reimbursable. The programmatic costs also hit FY23/24 disproportionally due to the match requirements of the grant program.

However, the grant ultimately covers 75% of total programmatic costs and the added benefit to the water contractors vastly outweighs the extra 8.5% rate increase that would be incurred. Additional benefits that will be realized for this cost include a commercial, industrial, and institutional (CII) sector Spatial Analysis to provide landscape area measurements (and non-functional turf measurement) needed for the CII standard of the statewide water conservation framework, a regional WaterSmart Plant Kit Program to convert 1.2 million square feet of turf to low water use landscaping, residential Water Smart Home Assessments, and additional QWEL trainings and development of a new QWEL greywater manual. Grant funds will be able to offset costs we would have incurred anyway for ongoing regional programs such as QWEL trainings, the annual Eco-Friendly Garden Tour, and the WaterSmart Plant Label Program, with some small expansion of this program included in the grant in direct support of marketing the WaterSmart Plant Kit program. Overall, however, these ongoing program costs will be significantly lower for the three-year period of the grant. Lastly, we are maximizing pre-award cost match to keep the programmatic match costs low.

The Water Conservation Subfund budget is otherwise only inclusive of what is needed to maintain existing successful regional programs of the Partnership, including the Water Education Program, Green Business Program, Garden Sense Program, Water Loss Working Group and Validation Services, QWEL Program, DIY Toolkit, Eco-Friendly Garden Tour, Russian River Friendly Landscaping, and the WaterSmart Plant Label Program.

Additional funding is included to sustain the Partnership regional outreach campaigns, website, and regional representation for the developing Urban Water Use Objectives. No expanded services would be included for the plant label program ($10,000) without the grant, and no reimbursement of future program costs for these ongoing programs would occur. The table below summarizes the budget and rates with and without the DWR grant.

S&P assigned a rating of “AAA” to the 2022 Bonds, the highest possible rating, which represented an affirmation of the existing credit rating on parity bonds. The 2022 Bonds were issued at a total interest cost of 3.32%. The refunding of the 2012 Bonds generated $311,771 of present value savings or approximately 4.04% of the par amount refunded.

Summary
The draft proposed budget for FY 2023/2024 is based on accomplishing the required elements of the Biological Opinion, maintenance of facilities, and continued implementation of hazard mitigation and reliability projects, and projects responsive to the drought conditions.

Sonoma Water recognizes the profound impact of natural hazards and the COVID-19 pandemic to many residents, businesses, and our retail water contractors throughout our county and beyond. In response to the far-reaching financial hardships, Sonoma Water made a conscious effort to keep rate increases at a minimum while continuing to maintain system reliability and public health and safety. Sonoma Water has consistently kept DRAFT

Sonoma Water vi Draft 2/28/2023
average rate increases at 4.62% and 4.68% over the past five and ten years respectively, lower than a 5% average rate increase, even with the 6.05% rate increase in FY 2022/2023.

Rate increases following the events impacting the county averaged 4.26% and were as follows:

• Rates collect 1.15x debt service in accordance with the provisions of the Water Transmission System Master Ordinance.

Budget and Rate Reduction Measures reflected in the March 1 draft budget:
• Decreased rate increase from 20% to 10.56% in part by deferring $2.4 million in operations and maintenance projects. Sonoma Water has been deferring millions of dollars of capital and maintenance projects annually to reduce rate increases. The $2.4 million in deferred maintenance projects in this FY 2023/2024 Draft Budget is the maximum that can reasonably be deferred. • Total expenditures budget is 4.91% lower than FY 2022/2023. • Capital Program is fully funded by the 2022 sale of $15 million in Revenue Bonds, grants, and fund balance. No contribution from Water Transmission O&M Fund.

DRAFT

Sonoma Water vii Draft 2/28/2023
• The contractors on the Santa Rosa AQ maintained their discretionary capital charge at $11 resulting in a rate of 10.56%. The contractors on the Petaluma AQ have decreased their capital charge to $0 reducing their rate to 9.42%. The contractors on the Sonoma AQ reduced their capital change from $38 to $34.90 reducing their rate to 10.56%.
• Use of $18.15 million in grants, fund balance, and bond proceeds reduces the rate increase from 51.44% to 10.56%.
o Use of Fund Balance: $12.3 million. Unable to use more prudent reserve and remain compliant with debt coverage covenant.
o Grant revenue: $2.99 million
o Bond proceeds: $2.86 million
• Water Transmission System Total Cost per Gallon is $0.004.

Factors affecting the Rate Increase:
• 8.5% decrease in budgeted water deliveries.
• Two years with actual water deliveries between 4% and an estimated 9% less than budget. • 2.5% decrease in total revenue.
• 4.5% increase in O&M costs.
• 77% of the rate increase is attributable to the O&M budget, 14% to debt service, and 8% to the subfunds (Water Management, Watershed Planning and Restoration, Recycled Water and Local Supply, and Water Conservation).
• The net effect of the Water Conservation Rate Increase (including or excluding the proposed Department of Water Resources grant) on the Total Water Transmission Rate Increase is 0.39%. • Increases in material and equipment costs for aging infrastructure and priority maintenance projects that can no longer be deferred, continued supply chain disruptions, long lead times on equipment, and the current inflationary environment are putting upward pressure on the Water Transmission System budget.
