Revenue Requirement
Revenue Requirement Overview Determines the amount of revenue necessary to meet all utility financial obligations on a stand-alone basis – Operating costs – Capital costs – Financial policies and targets Evaluates existing revenue levels for sufficiency Develops a multi-year rate implementation strategy

Storm Considerations Existing Storm rates are not sufficient to meet ongoing obligations – Operating expenses are subsidized by Streets – Capital costs are paid for through the infrastructure fee – All customers pay an equal Storm fee per account Items for consideration: – Transition Storm utility to self-sufficiency • Eliminate Streets subsidy and infrastructure fees – Bill customers based on Equivalent Service Units (ESUs) • Tied to impervious surface area for Non Single Family customers • Very common industry rate structure • Shifts revenue collection from Single Family to Non Single Family (Commercial) customers commensurate with their impervious surface area FCS GROUP
Page 11
Storm Scenarios Scenario 1 (S1): – Self sufficient Storm rates starting March FY2018 • Not enough time to convert billing system to ESU billing – Convert to ESU rates starting September FY2019 followed by increases in July of 2020 and thereafter Scenario 2 (S2): – Delay rate implementation until July FY2019, and July of every year thereafter • Allows time for conversion to ESU rates • Requires an additional subsidy to meet expenses in FY2018 of $328,700.

Cost of Service
Cost of Service An equitable distribution of cost shares that considers utility specific data: – Measures of usage and demand – Planning, engineering and design criteria – Facility requirements Total cost by customer class (equity) Unit costs ($/usage; $/customer) Fundamental question: do cost differences exist to serve different customer classes of service
FCS GROUP
Page 20
Cost of Service Process Step 1: Allocate total utility cost by function
Water Utility Functions** Customer Meters & Services Base Demand (average use) Peak Demand (peak use) Fire Protection
Sewer Utility Functions** Customer Flow Strength
Step 2: Assign allocation factors using class specific information Step 3: Allocate costs to customer classes
** Industry Standard Methodologies; AWWA Principles of Water Rates, Fees and Charges, M1 Manual and the Water Environment Federation Financing and Charges for Wastewater Systems Manual 27

Rate Design
Rate Design
Produce sufficient revenue to meet utility financial requirements Cost based and equitable Collect the target revenue level for each class of service Meet the goals and objectives of the utility Rate design considerations: – Phase-in cost of service overall increases – Eliminate water allowance of 1,000 gallons
FCS GROUP
Page 28
Water Rate Design Options Option 1: Across the board – uniform percentage increases to fixed and variable charges – No structure changes Option 2: Phase in towards cost of service – Eliminate allowance for all classes of service – Differentiate rates by class of service (existing rates are the same)
