Workshop #7 Review & Public Comment• 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 input of the CIP and Cash, asking for input on DRAFT rate adjustments

Increases necessary to support Debt Coverage. Low DSCR of 1.30x in FYE 2022.
Should Desal not move forward following proposed adjustments, increases could be lessened without new 218 Process
Min forecasted DSCR is 1.63x.
Predicting demand “Bounce Back” timing and rate could impact proposed revenue adjustmentsWith 25% cutback, 33% increase would be 100% Bounce Back
Alt #1 (Baseline)No Bounce back
• Maintain CY 2015 levels
• Conservative approach and assumes any uptick in demand will be offset by further efficiency and conservation
• No revenue impact
Alt #2: 25% Bounce Back
• Drought and el Niño continue to impact 2017 demands
• 8% demand increase in 2018
• Est. revenue impact• $1.5M increase in 2018• $7M through 2021
Alt #3: 50% Bounce Back
• Drought and el Niño continue to impact 2017 demands
• 16% demand increase in 2018
• Est. revenue impact• $3M increase in 2018• $14M through 2021
District always maintains the ability to not implement the full proposed increase.
Water Rate Design
Water: Based on previous workshops, modeled water rate design responds to the Board’s request
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 $10.7 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
