Restore the Delta, Dr. Jeffrey Michael
Respond to Controversial California
WaterFix Benefit-Cost Analysis
O
n September 20, the California Depart-
ment of Water Resources (DWR) released
a Benefit-Cost Analysisfor the Delta Tunnels
written by Dr. David Sunding of the Brattle
Group claiming that the California WaterFix
could bring “billions of dollars in benefits” to
those who receive their water from partici-
pating State Water Project (SWP) contractors.
The benefits include “improved water
quality, more reliable water supplies,
enhanced disaster preparedness, and climate
change resilience,” according to Sunding, a
professor of natural resource economics at
UC Berkeley.
In his initial response, Dr. Jeffrey Michael,
the Executive Director of the Center for
Business and Policy Research at the Univer-
sity of the Pacific, pointed out four major
flaws in the analysis, including the assump-
tion of a “massive new subsidy” for agricul-
tural users cost share from urban water user
and the dependence of the positive bene-
fit-cost on a “dubious new benefit”: the value
of sea-level rise protection benefits.
In Sunding’s report prepared for DWR,
Sunding said, “The analysis described in this
report demonstrates that investment in the
California WaterFix results in positive net
benefits for the SWP urban and agricultural
contractors.”
He claims that economic analysis summa-
rized in the report goes beyond what is legally
required for WaterFix and is “consistent
with methods” described in the department’s
“Economic Analysis Guidebook.”
The analysis concludes that the WaterFix
benefits to SWP water agencies are “substan-
tial.” Urban agencies could see about $3.1
billion in net benefits, while WP agricultural
agencies could see about $400 million in net
benefits, Sunding claims.
“The report compared the benefits and costs
of WaterFix in relation to what would likely
occur if WaterFix were not built, including
further restrictions on existing SWP and CVP
operations designed to minimize harmful
reverse flows and protect species,” according
to Sunding.
“Without WaterFix, State Water Project
contractors will see the continued deteriora-
tion of their water supply reliability,” Sunding
said. “This analysis shows there is substantial
benefit for both urban and agricultural water
users throughout the state, and that the project
will be more affordable for consumers than
local alternatives such as desalination and
recycling.”
He added that the analysis also indicates that
“CVP south of Delta contractors would realize
positive net benefits were they to utilize and pay
for access to the new north Delta conveyance
facilities.”
A controversial feature of the report is that it
monetizes the cost of climate change impacts and
the benefits of offsetting those impacts.
“WaterFix helps mitigate the impacts of
climate change on the state’s water supply
system,” Sunding said. “This feature of the
WaterFix alone is worth several billion dollars
and is an important rationale for implementing
the project.”
The economic analysis is available here.
Dr. Jeffery Michael published blog post of his
initial reaction to Dr. Sunding’s work, focusing
on four errors within Dr. Sunding’s analysis:
1. “It assumes a massive new subsidy for agri-
cultural users cost share from urban water users.
The agricultural subsidy is contained within a
“wheeling rate” that it assumes that Metropolitan
Water District (MWD) would charge the Central
Valley Project (CVP) for using the tunnels’
conveyance capacity.
2. “The positive benefit-cost ratio depends on
a dubious new benefit: the value of sea-level
rise protection benefits. The report estimates the
present value of these sea-level rise benefits at
a whopping $5.7 billion, a value that exceeds
the study’s estimated total net benefit of the
WaterFix. That means the benefit-cost ratio is
negative for all user categories if this dubious
new benefit is removed. This estimated benefit
has never been included in any previous study of
WaterFix, and thus it is a new benefit category
created for this report when the old methodology
fell short of giving a positive benefit-cost ratio.
3. “The report, press release and webpage
falsely claim that this benefit-cost analysis is
consistent with DWR’s Economic Analysis
Guidebook. The Economic Analysis Guidebook
clearly states that “Although economic analyses
can be evaluated from many different perspec-
tives (individuals, communities, etc.), DWR
conducts these analyses from a statewide
perspective.” The report is clear, even in its
title, that it is an analysis from the perspective
of water agencies that participate in WaterFix.
It does not consider statewide impacts—which
include costs to other water users or the envi-
ronment - both of which are very large for this
project.
4. “The single-tunnel scenario is clearly better
for MWD and urban water users if one compares
this study to a February
2018 analysis of single-
tunnel by the same
consulting firm. While
