Workshop #4, 5, & 6 Resulting Rates & Customer Impacts• Rate design and calculation

• Review of customer impacts

Workshop #7Cost of Service Refinement• Address received feedback

• Overview of previous presentations

The Board provided general direction on the following items:

• Rates to be increased gradually rather than “just in time”• Greater recovery of fixed expenditures• General Rate Structure Revisions

– Simplify existing structure– Stabilize revenues & cost recovery– Updates based on Cost of Service

Board provided specific direction throughout Workshops 3, 4, and 5.

• Sewer Rate Considerations– SFR: Fixed structure with 3 volumetric blocks– SFR: Sewer usage proxy based on Winter Quarter Average– Commercial: Simplify 20 classes to 3 categories

• Water Rate Structure Alternatives– SFR: Revise structure to 3 tiers (from 5) – Unique uniform rates for MFR, commercial, potable irrigation– Affirmed outlined Fixed & Demand Charge methodology

• Recycled Water– Fixed + Variable structure, with no demand charge

• Preliminary Revenue Requirement Analysis– Desire to move forward assuming funding of O&M, R&R CIP, and both

the Tunnel and Desal Projects– Requested funding alternative if Desal was not moved forward

Workshop #5 outlined three high level revenue scenarios for discussion

• Revenue Requirement Scenarios1. Operation & Maintenance (O&M) and

Repair & Replacement (R&R)2. O&M, R&R, and Tunnel Project Only3. O&M, R&R, Tunnel, and Desal Projects

• Received general consensus for Scenario #3– Although the decision to move forward with Desal is not final,

Scenario #3 provides greater flexibility• Additionally, Board requested Staff review the following:

– Forecasted Draft 5‐year CIP– Reserve Policy– District Debt Policy

Revenue RequirementsAnalysis

Based on refined financial forecast, requesting Board to

approve presentation of final rates at next workshop

Water Rate Design

Water: Rate design updated to reflect changes in water demands and system utilization

Existing Rate Design• Two Components

– Fixed + Variable Charge

• SFR – 5 Tiers

• MFR – Uniform

• Commercial – Uniform

• Potable Irrigation – Tiered Allocation

• Recycled Water – 90% of Commercial Rate

Modeled Rate Design• Three Components (Potable)

– Fixed + Demand + Variable

• Class specific variable design– SFR – 3 Tiers – MFR – Uniform– Commercial – Uniform– Potable Irrigation – Uniform

• Recycled Water– Fixed + Variable

Shown at Workshop #4

Water: Rate design philosophy is founded on cost of service principles and SCWD’s system & utilization

Three rate components designed to reflect Cost of Service (pertains to all potable water classes):1. Fixed Charge

– Recovers fixed costs based on provided capacity– Collected on the tax roll

2. Demand Charge– Recovers fixed costs based on utilized capacity– Collected on the tax roll

3. Variable Charge– Volumetric based charge, per CCF, based on variable costs– Billed monthly

Shown at Workshop #4

Water: Proposed Fixed Service Charges are set to recover half of fixed costs

Fixed Allocation $9.7 Million

** Ratios based on gallon per minute (gpm) flows relative to a ¾” meter. For example, a 1” meter with a flow of 50 gpm is divided by the ¾” flow of 30 gpm to achieve a 1.67 ratio

Water: Remaining fixed costs to be recovered through the new Demand Charge

FY ‘17 Demand Charge Calculation FY ‘17 Methodology

• Blue area represents underutilized fixed costs (capital and distribution)

• Based on 2nd highest month– Minimizes adjustments

• Individualized per account

• Encourages Conservation
