The
SFPUC
conducted
its
own
initial
technical
assessment
of
the
potential
effects
of
climate
change
on
its
Regional
Water
System
and
found
that
through
2025
a
projected
temperature
increase
of
1.5
degrees
Celsius
would
result
in
about
7
percent
of
the
runoff
that
now
drains
into
Hetch
Hetchy
Reservoir
shifting
from
the
spring/summer
season
to
the
fall/winter
season.
The
percentage
change
is
within
the
annual
variation
in
spring/summer
runoff
that
already
occurs
and
is
accounted
for
by
the
SFPUC’s
supply
system
management
and
planning
such
that
it
would
not
adversely
affect
supply
delivery
projections
or
capabilities.
The
SFPUC
is
now
proceeding
in
partnership
with
other
water
utilities
across
the
country
and
research
programs
to
develop
additional
evaluation
methods
to
further
evaluate
potential
climate
change
effects
on
water
supply.
Information
from
Draft
EIR
Section
4.N,
Traffic
and
Circulation
,
relevant
to
the
analysis
of
potential
GHG
impacts
consist
primarily
of
the
vehicle
trips
generation
assumed
for
each
development
scenario.
This
data
was
presented
in
Tables
4.N-12
and
4.N-13
of
the
Draft
EIR.
Please
see
and
The
BAAQMD
CEQA
website
identifies
CalEEMod
as
the
model
to
be
used
in
CEQA
analysis
as
of
August
5,
2013,
which
was
subsequent
to
the
release
of
the
Draft
EIR
in
June
of
2013.
The
Final
EIR
includes
an
updated
estimation
of
Project
Site
development-related
GHG
emissions
based
on
the
latest
version
of
the
CalEEMod
model.
The
updated
emission
inventory
is
provided
Section
4.F,
Greenhouse
Gas
Emissions
,
of
Volume
III
of
the
Final
EIR.
Based
on
the
latest
version
of
the
CalEEMod
model,
GHG
emissions
under
the
CPP
and
CPP-V
scenarios
are
estimated
at
3.2
metric
tons
per
year
per
service
population,
and
are
below
the
GHG
significance
threshold.
Consequently,
the
CPP
and
CPP-V
scenarios
are
now
identified
as
having
a
less
than
significant
impact
with
regard
to
GHG
emissions.
Models
used
to
calculate
GHG
emissions
from
the
developer-sponsored
plan
included
in
the
Draft
EIR
were
URBEMIS
and
the
Bay
Area
Greenhouse
Gas
Model.
The
CalEEMod
land
use
emissions
model
of
the
California
Air
Pollution
Control
Officers
Association
was
also
used
for
the
revised
calculations
included
in
this
Final
EIR.
These
models
were
the
recommended
models
for
GHG
analysis
at
the
time
of
the
Draft
EIR
and
Final
EIR,
respectively.
Input
data
for
vehicle
trip
generation
was
derived
in
the
Transportation
analysis
using
the
Institute
of
Transportation
Engineers
(ITE)
Trip
Generation.
