Home My WebLink AboutRexburg Water Sewer and Sanitation Rate and Capitalization Fee Study Presentation 7-3-26 Council Workshop Water, Sewer, and Sanitation Rate Study and Capitalization Fee Analysis Angie Sanchez Virnoche, Principal Angie Hammrich, Project Manager CITY OF REXBURG 1 Overview FCS retained to complete a Water, Sewer, and Sanitation Rate Study and a Capitalization Fee Analysis. Multi-year financial plan providing a forward look at each system’s needs Cost-of-Service Analysis and Rate Design for each system Capitalization Fee Analysis for water and sewer. Focus for today: Overview of the Rate Study Capitalization Fee Analysis results Present key data inputs and assumptions Summary of findings for each system Questions 2 Why A Rate Study? Enables each utility to remain self-sufficient Enables long-term fiscal sustainability Informs financial decisions and their impact Develops capital funding plan and evaluates future needs Living Plan sets rate path to achieve long-term planning objectives 3 Key Rate and Fee Study Components Revenue Requirement Financial Plan “Define Overall system Needs” Cost of Service Analysis “Equitable Cost Allocation” Rate Design “Collect Needed Revenue” Capitalization Fee “Determine Value of system capacity” Meetings, Presentations, Documentation 4 Governing Statutes/Guidance Idaho Code Title 50, Chapter 10 Finances Section 1030(f) allows cities “to prescribe and collect rates, fees, tolls or charges” Section 1032 “shall be and always remain self-supporting” Provide for all expenses of operation and maintenance of such works*, bonds, and interest, including reserves Capitalization Fees 2015 Idaho Supreme Court Ruling NIBCA** v. City of Hayden Identifies methodology to calculate connection/capitalization fees - Loomis v. Hailey Does not allow for including future facility costs *The term “works” shall include water systems, drainage systems, sewerage systems **NIBCA = North Idaho Building Contractors Association Start with statutes as they provide the authority and guidance for what is being requested. 5 Capitalization Fee Analysis 6 Overview of Capitalization Fees One-time charge, not ongoing rates Recovers value of system capacity new user will utilize Based on the replacement cost of system infrastructure investment Includes only existing infrastructure in use Calculated fee represents maximum allowable For capital use only 7 Overview of Capitalization Fees (cont.) Fee based on specific asset investment for each system Focus is value of system capacity rather than revenue producing 8 Capitalization Fee – Water Current Fee $2,403 MAX Capitalization Fee Supply & Pumping: $.30 per GPD Storage: $1.15 per GPD Transmission & Distribution: $1.14 per GPD Residential: 1,825 GPD $4,727 No Outside Cap Fee 9 Capitalization Fee – Sewer MAX Capitalization Fee Current Fee: $1,869 Residential – 198 GPD: $2,151 Rexburg Capitalization Fee: Treatment: $5.45 per GPD + Collection Rexburg: $4.47 per GPD +Shared Collection – Rexburg: $.94 GPD = $10.86 per GPD Shared Collection – Sugar City/Teton: $.94 per GPD each + Treatment $5.45 per GPD for each No Outside Cap Fee 10 Water Utility – Monthly Rates 11 Revenue Requirement Overview Determine the amount of annual revenue necessary to fund all financial obligations on a standalone basis Operating expenses | debt service (principal & interest) | capital Meet financial parameters and targets (coverage | reserves) Evaluate revenue sufficiency over a multi-year period Develop a rate plan to balance financial needs and minimize customer impacts 12 Forecast Basis Study Period: 2025-2030 Budget FY 2025/2026 Used as a baseline Financial Forecast Key Assumptions Customer Growth Water: 2.15% per year Operating Reserve Target Water: 120 days $1.09 – 1.17M Existing Debt Service Water: $6.9M Capital Plan 2025-2030 Water: $33.7M Expense Inflation 3.50% to 4.00% annual cost inflation Annual Rate Revenue Water: $4.6 – 5.0M 13 Capital and Funding 2025-2030 $33.7M capital costs Funding Sources S.
