EXHIBIT 3, ATTACHMENT A
Appendix K — Reporting on Reduced Delta Reliance
Regulatory Background
Urban water suppliers that anticipate participating in or receiving water from a proposed project,
such as a multiyear water transfer, conveyance facility, or new diversion that involves transferring
water through, exporting water from, or using water in the Sacramento-San Joaquin Delta (Delta)
are required to demonstrate reduced reliance on the Delta in their 2015 and 2020 Urban Water
Management Plans (UWMPs) that can then be used in the certification of consistency process to
demonstrate consistency with Delta Plan Policy WR P1, Reduce Reliance on the Delta Through
Improved Regional Water Self-Reliance (California Code Regulations, Title 23, §5003).1 The Delta
Plan Policy WR P1 identifies the UWMP as the tool to demonstrate consistency with the state policy
that suppliers that carry out or take part in covered actions must reduce their reliance on the
Delta.'
Carlsbad Municipal Water District's (CMWD) information on its reduced reliance on the Delta is
documented below and can be used in future certifications of consistency with WR P1 for potential
future water supply covered actions in the Delta.
Carlsbad Municipal Water District Reliance on Delta Watershed
CMWD currently has two local water supplies, recycled water and desalinated seawater. The
remainder of CMWD's potable water supply is purchased from the San Diego County Water
Authority (Water Authority). In 2015,100% of CMWD's potable water was imported water supplied
by the Water Authority. The Water Authority's imported water supplies are primarily sourced from
the Colorado River via transfers from Imperial Irrigation District (IID), and from the State Water
Project (SWP) and Central Valley Project (CVP) via Metropolitan Water District of Southern
California (MWD).
CMWD's only imported water supplies that originate in the Delta watershed are imported water
supplies delivered by the Water Authority via MWD. Recognizing that the Delta supplies are
threatened by uncertain long-term reliability issues associated with drought shortages, climate
change, seismic events, environmental impacts, and flow restrictions, and that imported water
purchases are becoming increasingly expensive, CMWD has taken actions to reduce demand for
imported water from the Water Authority as supplied by MWD, and is continuing to explore future
opportunities to continue to reduce its reliance on imported water.
As part of its Draft 2020 UWMP, the Water Authority completed a Delta Reliance analysis to
evaluate reduced Delta reliance consistent with Appendix C in the California Department of Water
Resources' (DWR) Draft UWMP Guidebook 2020 (DWR Guidebook). Given that CMWD's only
potential source of water from the Delta watershed is water purchased from the Water Authority,
CMWD relies on the Water Authority's Delta reliance analysis to also demonstrate reduced regional
reliance on the Delta.

Water Authority Reduced Reliance on Delta Watershed
The Water Authority’s Draft 2020 UWMP documents consistency with WR P1 by quantifying the
water supplies that contribute to regional self-reliance and demonstrating reduced reliance on the
Delta watershed, as summarized below.
Quantification of Water Supplies that Contribute to Regional Self-Reliance
Water suppliers must report the expected outcome for measurable improvement in regional self-
reliance as a reduction in water used from the Delta watershed. Table 1 lists the sources of water
supplies and volumes that contribute to regional self-reliance.3 As shown in the table, the Water
Authority’s reliance on the Delta watershed, and consequently CMWD’s reliance on the Delta
watershed, decreases over time as the percent of water supplies that contribute to regional self-
reliance increase over time. CMWD’s individual supplies that contribute to regional self- reliance
can be found in Chapter 6 Water Supplies in CMWD’s 2020 UWMP.
Table 1 – Calculation of Supplies Contributing to Regional Self-Reliance
Demonstration of Reduced Reliance on Water Supplies from the Delta Watershed
Water suppliers are required to report on the expected outcomes for measurable reductions in
water supplies from the Delta watershed. For CMWD, the only potential source of water from the
Delta watershed is water purchased from the Water Authority via MWD. Because water provided
by the Water Authority via MWD can include supplies that comingle Delta watershed and CVP
supplies, and because MWD has not provided the anticipated methodology approved by the DSC,
the Water Authority (and therefore CMWD) has incorporated the MWD’s forecast in its entirety as
a reasonable methodology to forecast the percent of MWD water supply from the Delta watershed
and the CVP. Table 2 calculates the reduced reliance on the Delta watershed within the entirety of
the MWD service area, to serve as a regional approach for this requirement.4

Table 2 – Calculation of Reliance on Water Supplies from Delta Watershed 5
The CVP/SWP contract supplies in Table 2 include MWD's SWP Table A and Article 21 supplies. 6 The
values in Table 2 do not include supplies from San Luis Carryover storage or Central Valley storage
programs. The transfers and exchanges of supplies from the Delta watershed shown in Table 2
include supplies from the San Bernardino Valley MWD Program, Yuba River Accord Purchase
Program, the San Gabriel Valley MWD Program, and other generic SWP and Central Valley transfers
and exchanges. Additional information can be found in Section 3.2 and Appendix 3 of MWD's Draft
2020 UWMP.7
