IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

FIRST APPELLATE DISTRICT

DIVISION FOUR

CITY OF PETALUMA et al.,
Plaintiffs and Appellants,
A134559
v.
COUNTY OF SONOMA et al., (Sonoma County
Super. Ct. No. SCV248948)
Defendants and Respondents.

In this action, plaintiffs City of Petaluma (the City), Petaluma River Council, and
other organizations and individuals (collectively plaintiffs) challenge the decisions of the
County of Sonoma (the County) and its Board of Supervisors and Planning Commission
(collectively defendants) to certify an environmental impact report (EIR), rezone portions
of the project site and make corresponding amendments to the County’s General Plan and
an area plan, and approve construction and operation of an asphalt plant.1 Plaintiffs

The petitioners and plaintiffs named in the operative complaint were the City,
Petaluma River Council, an unincorporated association, Madrone Audubon Society, a
California nonprofit corporation, Friends of Shollenberger Park, an unincorporated
association, Moms for Clean Air, an unincorporated association, Petaluma Tomorrow, an
unincorporated association, David Keller, Andrew Packard, Ryan Phelan, Stewart Brand,
and Marjorie Helm. The named respondents and defendants were the County, the Board
of Supervisors of the County of Sonoma, and the Planning Commission of the County of
Sonoma. The named real parties in interest and respondents were The Dutra Group, a
California corporation, CSW/Stuber-Stroeh Engineering Group, Inc., a California
corporation, Corto Meno Sand & Gravel, LLC, a California limited liability company,
Peach Tree Terrace, a California general partnership, and Shamrock Materials, Inc., a
California corporation.

appeal the judgment entered after the trial court denied their petition for writ of mandate
and complaint for declaratory and injunctive relief. They contend defendants’ actions
violated the California Environmental Quality Act (Pub. Resources Code, § 21000 et
seq.) (CEQA) and the Ralph M. Brown Act (Gov. Code, § 54950 et seq.) (Brown Act)
and that the project conflicts with and violates the County’s General Plan. We affirm the
trial court’s judgment.
I. BACKGROUND
The County, as lead agency, published a draft EIR (DEIR) in January 2008 for the
Dutra Haystack Landing Asphalt and Recycling Facility (the project). The DEIR
described the project as “construction and operation of an asphalt batch plant, an asphalt
recycling area, and an aggregate materials off-loading, storage and distribution facility
for Dutra Materials (aka The Dutra Group). The proposal [originally] include[d] the
construction and operation of new dock facilities within and adjacent to the Petaluma
River for the receipt of barged aggregate materials, a conveyer and distribution system,
stockpiled aggregate materials, sand and recycled asphalt and concrete, an asphalt mixing
and loading facility, a portable asphalt and concrete recycling plant, and related office
with truck scale.”
The project site is located on three parcels (019-220-001, 019-230-022, and 019-
230-023) totaling 38 acres, between Highway 101 on the west and the Petaluma River on
the east. Shamrock Materials, Inc. (Shamrock) occupies an adjacent parcel to the north.
Shamrock provides aggregate storage and distribution to the construction trade, and has a
barge off-loading facility on the Petaluma river. According to the DEIR, The Dutra
Group (Dutra) had an existing temporary asphalt batch plant at another site, which it
would relocate to the project site.
In approving the project in December 2010, the board certified a final EIR (FEIR),
which consisted of the DEIR, responses to comments on the DEIR, and several other
documents. As approved in 2010, the project included amendments to the County’s
General Plan to designate two of the parcels Limited Industrial, and a use permit for the
asphalt batch plant. Five hundred thousand tons of aggregate materials and sand for the

2
plant were to be imported through the existing barge off-loading facility on the Petaluma
River, rather than through the new dock facility originally proposed. The materials would
then be brought to the plant by conveyor. Until the conveyor was operational, for an
interim period of no more than three years, these materials would be trucked to the site.2
Plaintiffs brought a petition for writ of mandate and complaint for declaratory and
injunctive relief, challenging the County’s approval of the project, and alleging
procedural and substantive deficiencies in the administrative proceedings. The trial court
denied the petition.
II. DISCUSSION
A. Standard of Review
“ ‘An appellate court’s review of the administrative record for legal error and
substantial evidence in a CEQA case, as in other mandamus cases, is the same as the trial
court’s: The appellate court reviews the agency’s action, not the trial court’s decision; in
that sense appellate judicial review under CEQA is de novo. [Citations.] We therefore
resolve the substantive CEQA issues . . . by independently determining whether the
administrative record demonstrates any legal error by the [agency] and whether it
contains substantial evidence to support the [agency’s] factual determinations.’
[Citation.]” (Madera Oversight Coalition, Inc. v. County of Madera (2011) 199
Cal.App.4th 48, 76 (Madera), overruled on another ground in Neighbors for Smart Rail v.
Exposition Metro Line Construction Authority (2013) 57 Cal.4th 439, 457 (Neighbors for
Smart Rail).)
“When the inquiry into legal error involves an EIR, the question can be phrased
generally as ‘whether the EIR is sufficient as an information document.’ [Citation.]
When the specific claim of legal error concerns an omission of required information from

2
As we will discuss below, the project underwent a number of changes during the
environmental review process, among them the deletion of a proposed new barge dock on
the Petaluma River to import aggregate materials; the extension of the proposed conveyor
system to convey materials from an existing barge dock on neighboring property to the
project site; and the use of trucks to import materials from the existing dock to the project
site during construction of the new conveyor system.

the EIR, the plaintiff must demonstrate that (1) the EIR did not contain information
required by law and (2) the omission precluded informed decisionmaking by the lead
agency or informed participation by the public. [Citation.] These two elements
constitute an abuse of discretion and prejudice, respectively, and together form reversible
error.” (Madera, supra, 199 Cal.App.4th at pp. 76–77.)
B. General Plan Consistency
In approving the project, the County approved a general plan amendment to
change the land use designation for two of the parcels at the project site (Assessor Parcels
019-320-022 and 019-320-023) from Limited Commercial to Limited Industrial, as well
as a corresponding zoning change.3 Plaintiffs contend this approval was inconsistent
with two policies of the County’s general plan.
Every city and county must adopt a “ ‘comprehensive, long-term general plan for
the physical development of the county or city, and of any land outside its boundaries
which in the planning agency’s judgment bears relation to its planning.’ (Gov. Code,
§ 65300.) The general plan has been aptly described as the ‘constitution for all future
developments’ within the city or county. [Citations.] ‘[T]he propriety of virtually any
local decision affecting land use and development depends upon consistency with the
applicable general plan and its elements.’ [Citation.]” (Citizens of Goleta Valley v.
Board of Supervisors (1990) 52 Cal.3d 553, 570–571.) “A zoning ordinance that
conflicts with a general plan is invalid at the time it is passed.” (Lesher Communications,
Inc. v. City of Walnut Creek (1990) 52 Cal.3d 531, 544.) Moreover, general plans must
be internally consistent. (Gov. Code, § 65300.5; see also Woodward Park Homeowners
Assn., Inc. v. City of Fresno (2007) 150 Cal.App.4th 683, 732; Citizens Assn. for Sensible
Development of Bishop Area v. County of Inyo (1985) 172 Cal.App.3d 151, 156, 175–
176.)

3
According to the County’s General Plan, “The ‘Limited Industrial’ land use
category provides sites for development to meet service and employment needs where the
range or scale of industrial uses is limited.” This category includes asphalt plants.

4
 In reviewing a claim that a project is inconsistent with a general plan, we are
mindful “that no project could completely satisfy every policy stated in the [general
plan], and that state law does not impose such a requirement. . . . Once a general plan is
in place, it is the province of elected . . . officials to examine the specifics of a proposed
project to determine whether it would be ‘in harmony’ with the policies stated in the plan.
[Citation.] It is, emphatically, not the role of the courts to micromanage these
development decisions. Our function is simply to decide whether the [officials]
considered the applicable policies and the extent to which the proposed project conforms
with those policies, whether the . . . officials made appropriate findings on this issue, and
whether those findings are supported by substantial evidence.” (Sequoyah Hills
Homeowners Assn. v. City of Oakland (1993) 23 Cal.App.4th 704, 719–720 (Sequoyah);
see also Endangered Habitats League, Inc. v. County of Orange (2005) 131 Cal.App.4th
777, 782 (Endangered Habitats League).) In other words, “ ‘[a] project is consistent with
the general plan “ ‘if, considering all its aspects, it will further the objectives and policies
of the general plan and not obstruct their attainment.’ ” [Citation.] A given project need
not be in perfect conformity with each and every general plan policy. [Citation.] To be
consistent, a subdivision development must be “compatible with” the objectives, policies,
general land uses and programs specified in the general plan. [Citation.] ’ [Citation.]
[¶] A city’s determination that a project is consistent with the city’s general plan ‘carries
a strong presumption of regularity.’ ” (Clover Valley Foundation v. City of Rocklin
(2011) 197 Cal.App.4th 200, 238 (Clover Valley).) In considering a general plan
amendment, we are mindful that such an amendment is a legislative act, and our review
“focuses on whether the Board acted arbitrarily, capriciously, or without any evidentiary
basis.” (Environmental Council v. Board of Supervisors (1982) 135 Cal.App.3d 428,
439–440.)
1. Development in Areas Subject to Flood
Policy 2.4 of the general plan establishes several criteria that “must” be met
before amending the plan to add a Limited Industrial designation. Among those is
criterion number 5, under which: “Lands shall not be in areas subject to flood, fire, and

5
geologic hazards or in areas constrained by groundwater availability or septic
suitability.”4 (Italics added.) The Board found specifically that the project site was not
subject to these constraints, stating in part, “The area proposed for development of the
asphalt plant is currently elevated . . . above the 100 year flood elevation . . . .” Plaintiffs
point out that the majority of the project site is in the Federal Emergency Management
Agency’s 100-year flood hazard zone as well as the County’s flood hazard zone. By
definition, they argue, areas within a floodplain are subject to flood.
One of the environmental impacts the EIR identifies is that the project would
“place within a 100-year flood hazard area structures which would impede or redirect
flood flows.” The EIR notes, however, that, “[a]lthough the project site is located within
the 100-year flood zone, the elevation of the proposed processing facilities would be
above the base flood elevation of 7 feet msl. Additionally, the base of the proposed
aggregate storage stockpiles would also be above the base flood elevation. Therefore, the
proposed facilities would not be expected to be flooded during the 100-year event.
Although the proposed grading for the site would result in placement of fill within
portions of the flood zone, excavation within the zone would occur as part of wetland

4
Under an earlier version of the General Plan, which was in effect at the time the
DEIR was prepared, this criterion provided that Limited Industrial “[l]ands shall not be in
environmentally sensitive or hazardous areas.” The preparers of the DEIR noted that the
proposed general plan amendment would include land that was in an environmentally
sensitive area and that was subject to floods and seismic hazards, and noted that the
mitigation measures did not all “involve avoidance of the environmentally sensitive and
hazardous areas, which appears to be the intent of Criterion #5.” The preparers of the
DEIR concluded this impact was significant and unavoidable. The County later found
that the general plan amendment was consistent with the goals, objectives, and policies of
the general plan. We reject plaintiffs’ contention that the County was bound by the
conclusions of the DEIR. For one thing, the DEIR considered a different general plan
provision than was in effect at the time of project approval. In any case, the authority
plaintiffs cite stands for the proposition that an earlier version of an initial study may
provide evidence to support a fair argument that a project may have a significant effect
on the environment. (Stanislaus Audubon Society, Inc. v. County of Stanislaus (1995) 33
Cal.App.4th 144, 152–154.) It does not persuade us that a county is bound by the
conclusions of the preparers of the DEIR on the ultimate question of whether a project is
consistent with the county’s unamended general plan.

6
enhancement. Analysis prepared for the project indicates that the proposed project would
increase the flood storage volume below elevation 7 feet msl [mean sea level] from 28.57
acre-feet (existing) to 32.53 acre-feet. The increases in flood storage would be expected
to incrementally reduce flood hazards within the Petaluma River by retaining more water
on-site during flooding events.” (Italics added.) The EIR thus concluded that changes to
flood hazard conditions would be less than significant.
In approving the project, the County found impacts from conflicts with land use
plans, policies, and regulations to be less than significant. As pertinent here, the County
agreed with the EIR, and concluded that “[t]he area proposed for development of the
asphalt plant is currently elevated (around 10 feet above mean sea level) above the 100
year flood elevation (7 feet above mean sea level)” and therefore met the criteria for an
amendment to the General Plan designation to Limited Industrial.
Plaintiffs contend this finding was improper because, even if the portion of the
parcels to be developed would be above the flood level, other portions of the rezoned
parcels would remain below that level, particularly “Area D,” a portion of Parcel 019-
320-022, which was to be preserved and restored as open space. As we have noted, a
project is consistent with a general plan “ ‘ “ ‘if, considering all its aspects, it will further
the objectives and policies of the general plan and not obstruct their attainment,’ ” ’ ”
even if it is not “in perfect conformity with each and every general plan policy.” (Clover
Valley, supra, 197 Cal.App.4th at p. 238.)
As plaintiffs point out, a public entity’s flexibility in interpreting its own general
plan is not limitless, and “[a] project is inconsistent if it conflicts with a general plan
policy that is fundamental, mandatory, and clear.” (Endangered Habitats League, supra,
131 Cal.App.4th at p. 782.) In Endangered Habitats League, the court ordered a
county’s approval of a project to be set aside where the project was inconsistent with the
county’s general plan in three ways. First, it would cause an unacceptable increase in
traffic on a local road when measured using the methodology specified in the general
plan. (Endangered Habitats League, supra, 131 Cal.App.4th at pp. 783–784.) Second, a
specific plan amendment allowing regulations to be “balanced,” conflicted with the

7
general plan policy that new developments must comply with all specific plan policies in
order to maintain a buffer between urban development and a national forest. (Id. at
pp. 785, 787.) Finally, the amendment exempted the project from otherwise mandatory,
more stringent, specific plan requirements regarding tree preservation, grading, and open
space, in violation of the general plan policy that all new development comply with all
specific plan policies. (Id. at pp. 785–787, 789.)
In the second case on which plaintiffs rely, Families Unafraid to Uphold Rural
etc. County v. Board of Supervisors (1998) 62 Cal.App.4th 1332 (Families Unafraid), the
court concluded a project was inconsistent with a county’s general plan’s policies that
required land designated low-density residential to be contiguous to the community
regions (larger towns or areas of development) or rural centers (smaller towns or areas of
development), and that required low-density residential lands not to be separated from
these areas by rural residential land-use designations. (Id. at pp. 1338–1339, 1341.) The
court reasoned, “the land use policy at issue here is fundamental (a policy of contiguous
development, and the Draft General Plan states that the ‘Land Use Element is directly
related to all other elements contained within the General Plan’); the policy is also
mandatory and anything but amorphous . . . . [¶] Moreover [the development’s]
inconsistency with this fundamental, mandatory and specific land use policy is clear—
this is not an issue of conflicting evidence.” (Id. at pp. 1341–1342.)
Thus, in both Families Unafraid and Endangered Habitats League, the projects
undermined the general plans’ fundamental land use policies. Here, on the other hand,
the area to be developed would be above flood level, and the excavation would increase
flood storage on-site and thereby reduce flood hazards within the Petaluma River.
Nor have plaintiffs convinced us that the General Plan’s prohibition on Limited
Industrial zoning in areas subject to flood is a “fundamental” policy, where the areas of
the property that will actually be developed lie above the flood level and flood storage as
a whole will be increased. On the facts of this case, the Board could reasonably conclude
the project, would not violate a “fundamental, mandatory, and clear” general plan policy
related to flooding.

8
 We also are not convinced by plaintiff’s argument that if the project does not go
forward, any subsequent purchaser of the property would be allowed to develop it in any
way permitted in the Limited Industrial zone despite the potential for flooding. Any such
development would, of course, be subject to any necessary review of its environmental
effects and its consistency with applicable general and area plans.
Plaintiff argues, however, that some of the area to be developed had not yet been
filled to above the flood level at the time of project approval, and that the County
therefore could not properly designate the property light industrial. The County found
that the area proposed for development of the plan “is elevated above the 100-year flood
elevation,” (italics added) and the record contains evidence that this area was already
elevated to that level. In any case, even if the filling was not yet complete, it is clear that
it will take place as part of the project, and we reject plaintiff’s contention that the project
is therefore inconsistent with the general plan.
2. River Dependent Uses
The portion of the General Plan’s Land Use Element that considers Petaluma and
its environs includes several objectives, including making Petaluma the commercial and
industrial center for the area. (Objective LU-19.2.) Among the policies to be used to
achieve these objectives is the following: “Policy LU-19c: Apply the ‘General
Commercial’ and ‘General Industrial’ categories only to appropriate uses existing as of
1986 inside the Urban Service Boundary. Apply the ‘Limited Commercial’ and ‘Limited
Industrial’ categories only to appropriate uses existing as of 1986. However, consider
additional river dependent commercial and industrial uses along the Petaluma River,
where necessary to maintain the river as a navigable waterway connecting the Bay to
downtown Petaluma.” (Italics added.)
The County found the project was consistent with these policies in that it “includes
the delivery of aggregates and sand from an existing adjacent barge off-loading facility
on Landing Way, and will maintain a link between the new facility and the Petaluma
River. The Board finds that the Proposed Project is river dependent because the
approved conveyor provides a permanent, fixed connection to river importation that must

9
be in close proximity to the river. The Board further finds that having a long-term, high-
volume customer connected with a fixed conveyor system increases the likelihood that
significant river-based aggregate importation will continue into the future, and the
Proposed Project is thus necessary to maintain the river as a navigable waterway.”
The EIR explains that “[t]he Petaluma River is actually a tidewater slough that
was designated a river in 1959 by Congress, which allowed the Army Corps of Engineers
(Corps) to permit dredging for commercial navigability access.” It also explains that
dredging occurs approximately every four years. However, as of 2010, the Corps
classified the river as “a shallow draft waterway with low commercial use,” and had not
dredged it since fiscal year 2003. The Corps explained in a letter to a County employee
that “while there is no action being taken to de-Authorize the Petaluma River channel
from the list of federally-maintained navigation channels, Federal projects with this
classification are low on the national priority list for fiscal year Appropriations.” Water
dependent industries along the riverfront formed part of the economic justification for the
Corps to dredge the river.
As approved, the project does not include any new barge docking facilities or off-
loading equipment along the Petaluma River. Rather, sand and aggregates would be
transported to the asphalt plant from an existing facility, Shamrock’s Landing Way
Depot, which imports materials from the river by barge. For the first three years (during
which the conveyor would be constructed) trucks would carry materials from the Landing
Way site to the asphalt plant. Thereafter, the new conveyor would carry materials from
the Landing Way Depot to the asphalt plant. A County staff report opined that the
conveyor option “provides a permanent, fixed connection to river importation that must
be in close proximity to the river and is therefore considered to be river-dependent.”
Plaintiffs contend the Board abused its discretion in finding the project fell within
Policy LU-19c’s provision that the County could consider the Limited Industrial category
for “river dependent” industrial uses that did not exist as of 1986. They argue that for the
three years that trucks are used to carry materials from the Landing Way Depot, the
project will not be river dependent because it will have no direct connection to the river.

10
Plaintiffs acknowledge that under the conditions of approval, the project will not continue
if the conveyor system is not constructed after three years; however, they contend, there
is no evidence that Dutra will in fact be able to construct a conveyor system to
Shamrock’s facility, and Shamrock has disclaimed any interest in the project. If the
conveyor system is not built, they argue, the project site will still retain its designation as
Limited Industrial, and this will violate the General Plan’s Policy LU-19c.
As we have already explained, a public entity’s finding that a project is consistent
with its general plan is entitled to a strong presumption of regularity. (Clover Valley,
supra, 197 Cal.App.4th at p. 238.) The applicable policy—that the County “consider
additional river dependent . . . industrial uses along the Petaluma River, where necessary
to maintain the river as a navigable waterway connecting the Bay to downtown
Petaluma”—by its nature vests discretion in the Board to determine whether a given
project is river dependent, and whether it will assist in maintaining the river as a
navigable waterway. There is conflicting evidence of whether the project would in fact
rely on the Petaluma River, and we will not reweigh that evidence. (See Sequoyah,
supra, 23 Cal.App.4th at p. 720.) We conclude that it was within the County’s discretion
to find that the project as a whole—including a limited period of trucking materials from
a depot on the river, followed by importing materials from the depot by a permanent,
fixed conveyor system—was river dependent for purposes of the general plan.
C. Baseline Conditions
The notice of preparation (NOP) for the Dutra project was published on February
17, 2006. The EIR explained that Dutra had previously operated an asphalt plant for 20
years and was currently operating its facility at another site, 1601 Petaluma Boulevard
South, under a temporary permit that would expire in 2008.5 The project would involve
relocating the temporary asphalt batch plant to the project site at 3355 Petaluma

5
It appears that the applicant had sold the property and its lease had expired with
no possibility of an extension, and that operations at the temporary facility ceased in
September 2007.

11
Boulevard South. It appears that the project site is between one-half mile and one mile
away from the site of the temporary plant.
In its discussion of air quality impacts, the EIR explained that “[b]ecause the
project involves the relocation and shutdown of the existing asphalt facility, the impact is
evaluated based on the net increase in emissions due to construction and operation of the
new facility.” Plaintiffs contend it was improper for the EIR to base its analysis on the
difference between the new plant’s anticipated emissions and the emissions of the
existing plant. Rather, they argue, since the existing facility was scheduled to cease
operations in 2008, the EIR should not have included emissions from that facility in its
baseline.
The State CEQA Guidelines (Cal. Code Regs., tit. 14, § 15000 et seq.
(Guidelines))6 require an EIR to “include a description of the physical environmental
conditions in the vicinity of the project, as they exist at the time the notice of preparation
is published, or if no notice of preparation is published, at the time environmental
analysis is commenced, from both a local and regional perspective. This environmental
setting will normally constitute the baseline physical conditions by which a lead agency
determines whether an impact is significant.” (Guidelines, § 15125(a), italics added.)
The Guidelines also provide that “[i]n assessing the impact of a proposed project on the
environment, the lead agency should normally limit its examination to changes in the
existing physical conditions in the affected area as they existed at the time the notice of
preparation is published, or where no notice of preparation is published, at the time
environmental analysis is commenced.” (Guidelines, § 15126.2, subd. (a); see also
County of Amador v. El Dorado County Water Agency (1999) 76 Cal.App.4th 931, 952.)
The Guidelines also require an EIR to evaluate a “no project” alternative, and provide,

6
“The CEQA Guidelines, promulgated by the state’s Resources Agency, are
authorized by Public Resources Code section 21083. In interpreting CEQA, we accord
the Guidelines great weight except where they are clearly unauthorized or erroneous.”
(Vineyard Area Citizens for Responsible Growth, Inc. v. City of Rancho Cordova (2007)
40 Cal.4th 412, 428, fn. 5 (Vineyard).

12
“[t]he no project alternative analysis is not the baseline for determining whether the
proposed project’s environmental impacts may be significant, unless it is identical to the
existing environmental setting analysis which does establish that baseline (see Section
15125).” (Guidelines, § 15126.6, subd. (e)(1).)
“[A]n inappropriate baseline may skew the environmental analysis flowing from
it, resulting in an EIR that fails to comply with CEQA.” (Citizens for East Shore Parks v.
State Lands Com. (2011) 202 Cal.App.4th 549, 557 (Citizens for East Shore Parks); see
also Cadiz Land Co. v. Rail Cycle (2000) 83 Cal.App.4th 74, 87.) An agency has
discretion to decide how existing physical conditions can best be measured, subject to
review for substantial evidence. (Communities for a Better Environment v. South Coast
Air Quality Management Dist. (2010) 48 Cal.4th 310, 328 (Communities).)
Plaintiffs in essence contend the County abused its discretion in failing to use
conditions that would exist after the time of the NOP as the baseline for evaluating the
project’s effects on air quality. The court in Citizens for East Shore Parks considered a
similar contention. There, the State Lands Commission approved a lease for the
applicant, Chevron U.S.A. Inc., to continue operating a marine terminal. (Citizens for
East Shore Parks, supra, 202 Cal.App.4th at pp. 553–554.) The EIR used a baseline that
reflected the current condition of the terminal, and—in an argument similar to the one
plaintiffs make here—the project opponents contended the baseline should have excluded
any operational use of the terminal, because the agency could have eliminated the current
conditions by refusing the renewal. (Id. at pp. 558, 560.) The Court of Appeal rejected
this argument, noting that under the CEQA Guidelines, the environmental setting at the
time of the NOP normally constituted the baseline. (Id. at p. 561.)
More recently, our Supreme Court addressed the question of whether an agency
has discretion to use projected future conditions, rather than existing conditions, as a
baseline. In Neighbors for Smart Rail, an EIR for a project had exclusively employed an
analytic baseline of conditions in the year 2030 to assess a project’s likely impacts on
traffic congestion and air quality. (Neighbors for Smart Rail, supra, 57 Cal.4th at
p. 445.) After reviewing appellate authority on the propriety of using future conditions as

13
a sole baseline, the court announced the following rule: “Projected future conditions may
be used as the sole baseline for impacts analysis if their use in place of measured existing
conditions—a departure from the norm stated in Guidelines section 15125(a)—is justified
by unusual aspects of the project or the surrounding conditions. That the future
conditions analysis would be informative is insufficient, but an agency does have
discretion to completely omit an analysis of impacts on existing conditions when
inclusion of such an analysis would detract from an EIR’s effectiveness as an
informational document, either because an analysis based on existing conditions would
be uninformative or because it would be misleading to decision makers and the public.”
(Neighbors, at pp. 451–452; see also id. at p. 457.)
Thus, in appropriate circumstances an agency may “adjust its existing conditions
baseline to account for a major change in environmental conditions that is expected to
occur before project implementation. In so adjusting its existing conditions baseline, an
agency exercises its discretion on how best to define such a baseline under the
circumstances of rapidly changing environmental conditions.” (Neighbors for Smart
Rail, at p. 452.) For example, the court went on: “in an EIR for a new office building, the
analysis of impacts on sunlight and views in the surrounding neighborhood might
reasonably take account of a larger tower already under construction on an adjacent site
at the time of EIR preparation.” (Id. at p. 453.) The court also noted that an agency’s
determination that an existing conditions impact would provide little or no relevant
information or would be misleading as to a project’s true impacts is reviewed for
substantial evidence. (Id. at p. 457.)
Thus, while Neighbors for Smart Rail recognizes the discretion of an agency to
include projected future conditions in a baseline in unusual circumstances, it does not
change the usual rule, expressed in the Guidelines section 15125, subdivision (a), that
baseline conditions are normally the physical conditions that exist at the time the NOP is
published. Whether or not the County could permissibly have exercised its discretion to
use other conditions as the baseline, an issue we do not decide, nothing in Neighbors for
Smart Rail leads to the conclusion that the County was required here to depart from the

14
usual rule. In light of the clear directive of the Guidelines and the decisions in Neighbors
for Smart Rail and Citizens for East Store Parks, we reject the contention that the County
violated CEQA by using conditions at the time the NOP was published as the baseline for
air quality impacts.
Plaintiffs attempt to distinguish Citizens for East Shore Parks on the grounds that
the project here will be located on a different site, and that the existing facility would
necessarily shut down. We are not persuaded that a project that involves the relocation of
a plant—even after an interim closure—takes this case outside the usual rule that baseline
conditions are measured at the time of the NOP.
Plaintiffs argue, however, that it was inappropriate to include the emissions from
the temporary plant in the baseline because the effects of certain pollutants—namely
PM10 and reactive organic gasses (ROGs)—are localized. Because the project site was
between one-half mile and one mile from the temporary plant, plaintiffs argue, it was
illusory for the impact analysis to assume those localized pollutants existed at the site of
the proposed new plant. They contend “[i]t defies reality that PM10 and ROGs emissions
half-mile away would accurately reflect the adverse impact of those emissions on the
residents living 300-feet downwind of the proposed Project site.”
However, the County points out that this contention does not appear to have been
raised at the administrative level. Public Resources Code section 21177, subdivision (a),
provides: “An action or proceeding shall not be brought pursuant to Section 21167
unless the alleged grounds for noncompliance with this division were presented to the
public agency orally or in writing by any person during the public comment period
provided by this division or prior to the close of the public hearing on the project before
the issuance of the notice of determination.” Under this rule, “ ‘[w]hen a ground for
noncompliance with CEQA was not raised during the comment period or during the
public hearing on project approval, the right to raise the issue in a subsequent legal action
is waived. The petitioner bears the burden of demonstrating that the issues raised in the
judicial proceeding were first raised at the administrative level. [Citation.] “[T]he
objections must be sufficiently specific so that the agency has the opportunity to evaluate

15
and respond to them” [Citation.] This requirement is known as the exhaustion doctrine.
[Citation.] The rationale behind this rule is that the public agency should have the
opportunity to receive and respond to articulated factual issues and legal theories before
its actions are subjected to judicial review.’ ” (Planning & Conservation League v.
Castaic Lake Water Agency (2009) 180 Cal.App.4th 210, 250; see also State Water
Resources Control Bd. Cases (2006) 136 Cal.App.4th 674, 794.)
Responding to the County’s assertion that the issue of localized impacts of PM10
and ROG had been raised for the first time on appeal, plaintiffs point in their reply brief
only to their briefing in the trial court. In doing so, they fail to meet their burden to show
the issue was raised at the administrative level. Our own review of the administrative
record shows that plaintiffs and their consultants submitted comments contending that
because the project was “an entirely new facility on a new parcel of property,” the project
was not a modification of an existing project and the baseline should therefore be zero;
and that as a result of including emissions from the temporary plant in the baseline, the
EIR failed to identify impacts due to emissions of ROGs, nitrogen oxides, and PM10.
However, these comments fail to make the point that certain substances, namely ROGs
and PM10, have a particularly localized impact that the EIR should have taken into
account in setting its baseline. Nor is there any indication plaintiffs drew the County’s
attention to any air quality effects that would be different at the location of the new plant
than at the temporary plant less than a mile away.
D. Changes to Project During Environmental Review
1. Background
As we have already noted, certain aspects of the project changed during the
environmental review process. The project as originally described in the January 2008
DEIR included the construction of “a barge facility on a fixed pier in and along the edge
of the Petaluma River to accommodate off-loading of aggregate materials for asphalt
production.” An enclosed conveyor system would carry the material approximately 940
feet over areas A and B before stockpiling it in Area C, the main operational area of the
project.

16
 After a number of hearings before the Board and the Planning Commission—and
after the FEIR had been presented—Dutra asked the Board to allow it to revise the
original project to address concerns that had been raised regarding noise, air emissions,
and aesthetic impacts. Dutra then proposed a revised project (Revised Project I), which
would reduce peak production by 25 percent, from 400 tons per hour to 300 tons per
hour; reduce the height of the silos at the project site from 76 feet to 62 feet, and
eliminate on-site crushing of recycled materials.
The United States Coast Guard later determined that the barges moored at the
facility would intrude into the federally maintained navigation channel and create a
navigational hazard to other users. In response, Dutra proposed a second revision to the
project (Revised Project II). In a staff memorandum to the Board prepared for an
October 12, 2010 hearing, Steve Padovan of the County’s Permit and Resource
Management Department explained that Revised Project II had been received by staff in
three letters, dated January 29, 2010, April 8, 2010, and June 10, 2010. Revised Project
II involved several changes from the original project: in addition to the changes already
discussed as part of Revised Project I, Revised Project II would include importation of up
to 500,000 tons annually of sand and aggregates from the existing Landing Way Depot
by truck and/or a conveyor system.7 The memorandum described this as the “most
substantial change” included in Revised Project II.
The staff memorandum explained, “[T]he proposed trucking route for materials
would consist of a short haul west on Landing Way, turning south on Petaluma
Boulevard South, left into the proposed facility and then returning back in the opposite
direction. If a conveyor system is utilized, the project would extend the originally
proposed conveyor that linked the facility to the river parcel (Area A) approximately 815
feet northward up to the existing barge off-loading facilities at Landing Way Depot. The
conveyor extension would be constructed a few feet above grade and parallel to the

7
Revised Project II also included a number of other changes: raising the pad
elevation of a portion of Area C of the project site, reconfiguring certain project
components, and redesigning a sound wall.

17
Petaluma River, over previously designated wetlands on the Landing Way Depot site, to
a joint use hopper that would serve both facilities. All off-loading, trucking and conveyor
operations for the new facility would be subject to the same hourly and seasonal
restrictions as those indicated in the Draft EIR, Response to Comments Document and in
Landing Way Depot’s existing Use Permit []. . . . Staff has . . . assumed that under the
conveyor option, materials would have to be trucked for an interim period as the
conveyor requires obtaining some type of easement over the SMART railroad tracks
which could delay construction. The interim trucking period proposed by staff is for
three years.”
The staff memorandum concluded, and the Board found, that Revised Project II
“would not result in any new significant impacts, any substantial increase in the severity
of any previously-identified significant impacts, any new, feasible alternatives or
mitigation measures that [Dutra] declines to adopt, nor otherwise trigger recirculation” of
the EIR under CEQA Guideline section 15088.5. Instead, the Board found, Revised
Project II would “result in fewer significant unavoidable impacts and significantly
reduced adverse impacts overall as compared with the Original Project.”8
Three of the potential impacts of Revised Project II are important to our review of
this case. First, the memorandum reported that Dutra’s consultant had found that the
construction of the extended conveyor system would affect a .48 acre wetland mitigation
area on the Landing Way Depot site, an impact that was considered potentially significant
absent mitigation. However, the wetland area was of poor quality, and only a small
portion of it would be filled. Dutra’s wetland specialist proposed mitigating the impact
through the purchase of mitigation credits at a wetland bank, about four miles from the
site, that had been authorized by state and federal resource agencies to provide in-kind
mitigation credit for local projects. The staff concluded that decommissioning the

8
The Board concluded the revisions would reduce the project’s impacts on
aesthetics, air pollution, biological resources, hydrology and water quality, noise, and
transportation and traffic, particularly with the adoption of the conveyor option.

18
wetlands and securing credits at the wetland bank would mitigate the effects on wetlands
to a less-than-significant level.
Second, Revised Project II could include truck traffic that was not part of the
original project or Revised Project I. The staff memorandum reported that the DEIR’s
consultant on air quality, BASELINE, had evaluated Dutra’s studies, the DEIR and
responses to comments, and information provided by Dutra, staff, and the truck engineer
on truck trips and site operations. The memorandum explained, “If the conveyor option
is utilized, there will be only minimal impacts to air quality from dust as the material is
conveyed and in the form of added GHGs [greenhouse gas] due to the production of
electricity to power the conveyor. However, the trucking operation will result in 43,478
additional truck trips per year (500,000 tons/23 tons per truck x 2).” The memorandum
noted that Dutra had provided several studies evaluating the changes to air quality
impacts that would result from Revised Project II.
An independent evaluation of Dutra’s studies, carried out by BASELINE, showed
that, “[u]nder the conveyor option, there are additional PM10 emissions not quantified in
the DEIR. If the conveyor system has no dust suppression equipment, then an additional
3.3 pounds of PM10 per day, or 0.28 tons per year would be produced. If sprayers are
used, PM10 emissions would be reduced to an estimated 0.14 pounds per day, or 0.011
tons per year. Based on the mitigation measures in the DEIR, sprayers would be
required. Furthermore, due to noise issues the conveyor will be enclosed. Indirect GHG
emission from the conveyor system would be approximately 24 tons of CO2eq annually,
assuming a 60 horse-power electrical motor would be required to run the conveyor
system. [¶] With regard to the trucking option, additional emissions of PM10, ROG,
NOx, and CO will be produced from the trucks transporting the raw materials the one-
half mile distance to the facility from the Landing Way Depot. These trucks would emit
an estimated 1.2 tons of PM10 (0.015 tons from vehicle exhaust and 1.2 tons from road
dust), 0.026 tons of ROG, 0.38 tons of NOx, and 0.11 tons of CO per year.” Using what
it characterized as a conservative approach, the memorandum reported that “the Revised
Project II, under the conveyor option, would result in a reduction in emissions relative to

19
the first revised project (which was an estimated 19 to 30% reduction in emissions from
the Original Project). Under the trucking option, the PM10 and CO numbers would
increase but still remain under the thresholds established by the Air District.” The
memorandum went on, “Excess cancer risk would not increase with the conveyor option
but may increase with the trucking option, remaining below the BAAQMD significance
threshold in either case. Cumulative impacts would also be reduced with the conveyor
option as materials would be transported to the project site using electric machinery.
[¶] Under either option, NOx emissions would remain significant and unavoidable but the
emissions would not violate any adopted thresholds. Significant cumulative effects
discussed in the DEIR would remain significant and unavoidable.”
Third, as to the effects of the additional truck trips on traffic, the staff
memorandum reported: “The Revised Project II, with the elimination of all barge
operations on Area A, substantially alters how materials are delivered to the site. Up to
500,000 tons per year of materials will now be imported from the Landing Way Depot
facility either by truck or conveyor. Under the conveyor option, the total number of truck
trips will remain the same as under the first revised project (101,304 trips). However,
under the trucking option, the total number of truck trips will increase to 144,782 or 16%
more than was projected in the Original Project in the DEIR []. Truck transfer of import
materials would consist of trucks exiting onto Petaluma Boulevard South at the Landing
Way Depot driveway traveling south to the Dutra Haystack Landing driveway and
returning. The present analysis treats this flow of traffic as added traffic above any
entitlement already accounted for in the Landing Way Depot Mitigated Negative
Declaration dated June 17, 2004.”
The original traffic consultant for the DEIR, Dowling Associates, analyzed the
traffic impacts of Revised Project II. Dowling found that under anticipated conditions for
2010 in addition to Revised Project II, the level of service (LOS) at the intersection of
Petaluma Boulevard South and Landing Way would fall from LOS E to F during the

20
morning peak hour.9 The staff memorandum concluded that the installation of a signal at
the intersection of Petaluma Boulevard South and Landing Way would mitigate the
impact, and that with the mitigation, the intersection would have a morning LOS of D,
and an afternoon LOS of C. Dutra would be required to install the signal before
beginning operations. Dutra would also be required to provide a fair share toward
providing a right turn lane which would reduce the delay at the intersection of Petaluma
Boulevard and the northbound ramp to US highway 101; as a result of this measure,
traffic conditions would be better than under the conditions analyzed in the DEIR.
In certifying the FEIR and approving the project, the County found that the
revisions to the project would not result in any new or substantially more severe
environmental impacts, any new, feasible mitigation measures or alternatives that the
applicant declined to adopt, or otherwise trigger recirculation of the FEIR. Rather, the
county found, the Revised Project II would result in reduced environmental impacts.
2. Accurate and Stable Project Description
Plaintiffs contend that the above-described changes to the project after the EIR had
been circulated were extensive enough that the EIR lacked an accurate and stable project
description. “The Guidelines specify that every EIR must set forth a project description
that is sufficient to allow an adequate evaluation and review of the environmental impact.
(Guidelines, § 15124.) . . . [¶] ‘[A]n accurate, stable and finite project description is the
sine qua non of an informative and legally sufficient EIR.’ . . . ‘[O]nly through an
accurate view of the project may the public and interested parties and public agencies
balance the proposed project’s benefits against its environmental cost, consider
appropriate mitigation measures, assess the advantages of terminating the proposal and
properly weigh other alternatives . . . .’ ” (San Joaquin Raptor Rescue Center v. County
of Merced (2007) 149 Cal.App.4th 645, 654–655.) However, “[t]he CEQA reporting
process is not designed to freeze the ultimate proposal in the precise mold of the initial

9
The EIR explains that “[f]acilities that operate at LOS E or worse are considered
deficient.”

21
project; indeed, new and unforeseen insights may emerge during investigation, evoking
revision of the original proposal.” (County of Inyo v. City of Los Angeles (1977) 71
Cal.App.3d 185, 199 (County of Inyo); see also Kings County Farm Bureau v. City of
Hanford (1990) 221 Cal.App.3d 692, 736.)
Plaintiffs contend the EIR does not meet these standards because it fails to
describe significant aspects of the project, particularly the extension of the conveyor
system and the temporary truck traffic as a result of the use of the existing Shamrock
barge dock to replace the proposed construction of a new barge dock closer to the asphalt
plant. In fact, they point out, the EIR states that an alternative to use the Shamrock barge
dock was considered and rejected as infeasible after Shamrock indicated that its facility
had no excess capacity available for asphalt aggregate. Thus, they argue, “a member of
the public reading the EIR would reasonably assume that the Shamrock barge dock
alternative was rejected.”
The court in Western Placer Citizens for an Agricultural & Rural Environment v.
County of Placer (2006) 144 Cal.App.4th 890, 898–899 (Western Placer) discussed the
effect of changes to a project during the environmental review process. The applicant
there proposed a project to mine and process sand, gravel, and granite, with mining and
reclamation to occur in nine successive phases. (Id. at p. 893.) Some of the land was
covered by California Land Conservation Act of 1965 (Williamson Act) contracts that
prohibited mining. (Id. at p. 894.) After the DEIR and a revised DEIR were circulated,
the developer met with county staff and proposed to implement one of the project
alternatives, but with a change in the phasing of the project that allowed it to avoid
mining on lands affected by Williamson Act contracts until the contract expired. (Ibid.)
The FEIR mentioned that the project could avoid Williamson Act conflicts by delaying
mining on lands affected by the contracts, but did not include a revised description of the
project reflecting the new phasing or analyze whether the change in phasing created
additional impacts. (Ibid.) The county certified the FEIR and approved the revised
project, and the trial court granted a writ of mandate, concluding the EIR had to be

22
revised to include the changes made to the project before the county decided whether the
changes were significant enough to require recirculation. (Id. at pp. 895, 899.)
The Court of Appeal reversed the judgment, reasoning, “The parties have directed
us to no provision in CEQA or the Guidelines, and we have found none, that requires all
changes made to a project after the final EIR is released but prior to certification to be
included in the EIR. [¶] The closest CEQA comes to addressing this issue is when it
discusses the requirement to recirculate an EIR. The relevant provision of CEQA,
section 21092.1, reads in part: ‘When significant new information is added to an
environmental impact report after notice has been given pursuant to Section 21092
[notice of availability of DEIR for public review] and consultation has occurred pursuant
to Sections 21104 and 21153, but prior to certification, the public agency shall give
notice again pursuant to Section 21092, and consult again pursuant to Sections 21104 and
21153 before certifying the environmental impact report.’ (Pub. Resources Code,
§ 21092.1.)” (Western Placer, supra, 144 Cal.App.4th at p. 899; see also Save Our
Peninsula Committee v. Monterey County Bd. of Supervisors (2001) 87 Cal.App.4th 99,
131 [if lead agency adds “ ‘significant new information’ ” to EIR after review, it must
recirculate revised EIR]; Chaparral Greens v. City of Chula Vista (1996) 50 Cal.App.4th
1134, 1146–1147.)
The court in Western Placer then reviewed the Guidelines on recirculation, and
explained that the statute and Guidelines “explain what to do when significant
information is added to an EIR, but they do not address whether an agency must add all
information to an EIR before determining whether the information is significant and
triggers recirculation.” (Western Placer, supra, 144 Cal.App.4th at p. 900.) After
reviewing the case law, the court concluded, “CEQA does not require a lead agency to
revise a final EIR to include any new information or project changes that arise after the
EIR is released but prior to certification before the agency determines whether the
information is significant enough to require the EIR to be recirculated.” (Id. at p. 903.)
Moreover, the county’s determination that the new phasing was not significant new
information requiring revision and recirculation of the EIR was given substantial

23
deference, and the challenger bore the burden of showing substantial evidence did not
support the determination. (Ibid.) Under Western Placer, we conclude the County was
not required to revise the EIR based on the changes to the project before determining
whether the new information was significant and required recirculation.
The two principal cases relied on by plaintiffs are inapposite. In Bakersfield
Citizens for Local Control v. City of Bakersfield (2004) 124 Cal.App.4th 1184, 1208, an
EIR failed to discuss why it had been determined that urban decay was not a significant
effect of the proposed project. In Russian Hill Improvement Assn. v Board of Permit
Appeals (1974) 44 Cal.App.3d 158, 167–168, no EIR was prepared for a project, and the
public entity made a post hoc effort to treat a collection of reports and hearings as the
equivalent of an EIR. Neither case concerned a project that underwent changes due to
concerns raised during the environmental review process, after circulation of the EIR.
But, we still must address the question of whether the changes to the project
constituted significant, new information that required the County to revise and recirculate
the EIR. As we have explained, the County’s decision not to do so is entitled to
substantial deference, and plaintiffs bear the burden of showing it is not supported by
substantial evidence. (Western Placer, supra, 144 Cal.App.4th at p. 903; see also North
Coast Rivers Alliance v. Marin Municipal Water Dist. Bd. of Directors (2013) 216
Cal.App.4th 614, 655–656 [recirculation unnecessary because substantial evidence
supported determination that new alternative added to FEIR was not feasible].) The
Guidelines provide that recirculation is required where “significant new information is
added to the EIR after public notice is given of the availability of the draft EIR for public
review under Section 51087 but before certification. As used in this section,
‘information’ can include changes in the project or environmental setting as well as
additional data or other information. New information added to an EIR is not
‘significant’ unless the EIR is changed in a way that deprives the public of a meaningful
opportunity to comment upon a substantial adverse environmental effect of the project or
a feasible way to mitigate or avoid such an effect (including a feasible project alternative)
that the project’s proponents have declined to implement. ‘Significant new information’

24
requiring recirculation include, for example, a disclosure showing that: [¶] (1) A new
significant environmental impact would result from the project or from a new mitigation
measure proposed to be implemented. [¶] (2) A substantial increase in the severity of an
environmental impact would result unless mitigation measures are adopted that reduce
the impact to a level of insignificance. [¶] (3) A feasible project alternative or mitigation
measure considerably different from others previously analyzed would clearly lessen the
significant environmental impacts of the project, but the project’s proponents decline to
adopt it. [¶] (4) The draft EIR was so fundamentally and basically inadequate and
conclusory in nature that meaningful public review and comment were precluded.”
(Guidelines, § 15088.5, subd. (a).) As our Supreme Court has explained, recirculation is
not mandated “when the new information merely clarifies or amplifies the previously
circulated draft EIR, but is required when it reveals, for example, a new substantial
impact or a substantially increased impact on the environment. [Citation.] . . . [T]he lead
agency’s determination that a newly disclosed impact is not ‘significant’ so as to warrant
recirculation is reviewed only for support by substantial evidence.” (Vineyard, supra, 40
Cal.4th at p. 447.)
Plaintiffs first point to Revised Project II’s effects on traffic. The DEIR had
discussed “Intersection Level of Service Impacts” and concluded that although the
project would affect the LOS at various intersections, including Petaluma Boulevard
South at Landing Way, the impact was less than significant and did not require
mitigation. The staff memorandum on Revised Project II reported that during the three-
year period when material would be imported from the Shamrock barge dock to the
asphalt plant by truck, the effects on traffic and the intersection of Petaluma Boulevard
South and Landing Way under 2012 conditions would be significant without mitigation,
but that the addition of a traffic signal at that intersection would mitigate the project’s
impacts. Plaintiffs do not argue substantial evidence does not support this conclusion,
but instead contend that even if mitigation reduced the impact to a less-than-significant
level, the EIR should have been revised and recirculated to address it. The plain wording
of the Guidelines persuades us otherwise. Although there would be an increase in traffic

25
impacts, substantial evidence supports the conclusion that the proposed mitigation would
reduce the impact to a level of insignificance. (See Guidelines, § 15088.5, subd. (a)(2).)10
We likewise reject the contention that the air quality impacts required recirculation
of the EIR. Despite the disagreement of plaintiffs’ consultant on the amount of road dust
that would be generated under the trucking option, the staff memorandum discussed
above points to substantial evidence that most of the air quality impacts of Revised
Project II would be lower than those of the original project, and that where there were
increased emissions under the temporary trucking option, they did not rise to a level of
significance.
Plaintiffs also assert the EIR should have been recirculated to examine the effects
of the conveyor on the Landing Way Depot wetland. In support they point out that the
conveyor will be built over a .48-acre wetland area that was created as part of the
mitigation required in connection with the 2004 approval of Shamrock’s Landing Way
facility. The 2004 Shamrock mitigation measure had provided: “Wetlands-related
impacts will be developed in consultation with the Corps in accordance with their
mitigation policies. . . . The creation of seasonal wetlands on the project site must be
approved by the Corps. As an alternative, if the Corps does not approve the creation of

10
Plaintiffs also point out that a consultant’s summary report prepared in
September 2010 describing Revised Project II stated incorrectly that one truck trip in and
one trip out would be required to transport 56,250 tons of “Recycled Input to/from
Landing Way Depot,” when in fact more than 2000 truck trips in each direction would be
necessary to import that amount of material. Plaintiffs raised this question below.
Drury’s consultants responded by acknowledging that the summary report had made
typographical and transcription errors, and stated that under Revised Project II, no
recycled products would be imported from the Landing Way Depot to the Dutra site, that
the recycled materials would come instead from “a variety of places throughout Sonoma
and Marin Counties similar to the original project,” and that “[t]he truck distribution is
similar to what was analyzed in the Draft EIR but with 15,625 fewer trips because Dutra
would be importing 93,750 fewer tons of recycled materials than previously proposed
and analyzed in the Draft EIR.” This provides substantial evidence that importation of
the recycled material does not substantially increase the traffic impacts analyzed in the
EIR.

26
the onsite seasonal wetlands, the applicant will purchase wetland creation credits at an
approved wetland mitigation bank equal to the size and kind of wetland habitat lost.”
The staff memorandum prepared for Revised Project II concluded that “[t]he
construction of the conveyor would impact the entire .48 acres, a potentially significant
impact absent mitigation. However, given the relatively low habitat quality of the
wetlands and the fact that only a small portion of the wetland area will be filled (piers to
support the conveyor), decommissioning of these wetlands and the securing of credits at
the Burdell Wetland bank would serve to adequately mitigate the impacts to these
jurisdictional wetlands to a less than significant level.”
The staff memorandum relied for this conclusion in part on a September 24, 2010
summary report for Revised Project II prepared by WRA, an environmental consulting
firm. The summary report explained that Shamrock’s seasonal wetland was of relatively
poor habitat quality and was dominated by non-native species. The report continued,
“Perhaps the greatest value of the seasonal wetland is its current function for filtering
surface runoff from the processing area before entering the river.” According to the
summary report, the Burdell Wetland Bank had been authorized by state and federal
resource agencies to provide in-kind wetland mitigation credits for projects within its
service area, which included the project site. The report concluded: “The loss of existing
wetlands in the wetland mitigation area on the Landing Way Depot site would be a
potentially significant impact under the Conveyor Option for the Revised Project II
beyond those impacts under the original project. However, given the relatively low
habitat quality of the existing wetland mitigation area, decommissioning this feature and
securing credits at the Burdell Wetland Bank would adequately mitigate this impact to a
less-than-significant level.” This provides substantial evidence to support a conclusion
that the impacts of Revised Project II on the Shamrock wetlands would not be significant.
We also reject plaintiffs’ argument that in allowing Shamrock’s wetlands to be
decommissioned, the County effectively deleted a mitigation required in 2004 for the
Shamrock project. This is not a case, like Katzeff v. Department of Forestry & Fire
Protection (2010) 181 Cal.App.4th 601, 614, or Lincoln Place Tenants Assn. v. City of

27
Los Angeles (2005) 130 Cal.App.4th 1491, 1508–1509, in which a previously ordered
mitigation measure was cancelled or disregarded without further environmental review.
Rather, the County allowed the use of the alternate means of satisfying the 2004
Shamrock wetlands mitigation measure—that is, the purchase of wetland credits, which
was expressly contemplated by that mitigation measure.
Additionally, plaintiffs argue that the EIR should have been revised to analyze the
potential adverse effect of noise and vibration from the conveyor on the endangered salt
marsh harvest mouse and other animals using the Shamrock wetlands. They point to a
letter from a biologist, James Castle, commenting on the conveyor option. Castle noted
that in 1990 the salt marsh harvest mouse had been found at the Alman Marsh, across the
river from the Dutra site, and that other species, such as the California clapper rail, the
California black rail, the white-tailed kite, and other species had also been found in the
Alman Marsh. There is evidence, however, that the conveyors are a “relatively minor
noise contributor as compared to the other noise sources,” that the noise generated by the
conveyors, as measured by nearby noise receptors, is below the existing ambient noise
levels in the area, and indeed, lower than the noise level in an office environment, that
vibration levels from the entire operation at an existing Dutra facility at another site
showed vibration levels below the level of perception, and that vibration levels from the
conveyor to endangered and threatened species at Alman Marsh and Shollenberger Park
would be negligible due to the distance between them and the Landing Way Depot site.
Moreover, a letter from WRA to the County reports that suitable habitat for the salt marsh
harvest mouse was absent from area A of the project site, and that the salt marsh harvest
mouse had not been found during surveys of the other areas. There was substantial
evidence to support a conclusion that the EIR did not need to be revised and recirculated
to address the effects of noise and vibration from the conveyor.
Thus, the County could reasonably conclude that none of the environmental
effects of Revised Project II’s extended conveyor constituted significant new information
that required recirculation. There is substantial evidence that none involved a new
significant environmental effect or a substantial increase in the severity of an

28
environmental effect absent mitigation, and we are not persuaded that extension of the
proposed conveyor to the existing Landing Way Depot site rendered the EIR’s project
description so inadequate as to preclude meaningful review. (Guidelines, § 15088.5,
subd. (a)(1), (2), & (4).) As we have explained, CEQA is not designed to freeze a project
description in place, but rather allows changes in response to concerns raised during the
review process. (County of Inyo, supra, 71 Cal.App.3d at p. 199.) That is what happened
here.
Finally, plaintiffs claim the EIR was inadequate because it failed to analyze the
effects of the project on the health of workers at the asphalt plant. One of the comments
on the FEIR stated that concentrations of particulate matter and silica would likely be
highest on the project site, where project employees and truck drivers would be exposed
to these contaminants; the commenter argued that the EIR should have evaluated these
health risks. In response, the County noted: “Worker health and safety is regulated by
the federal Occupational Safety and Health Administration (OSHA) and California’s
Division of Occupational Safety and Health (Cal-OSHA). The regulatory bodies set the
maximum permissible exposure limits (PELs) for worker exposure to toxic air
contaminants and the law requires that employers do not expose workers to
concentrations above these levels. Section 5(a)(1) of the Occupational Safety and Health
Act, often referred to as the General Duty Clause, requires employers to ‘furnish to each
of [their] employees employment and a place of employment which are free from
recognized hazards that are causing or are likely to cause death or serious physical harm
to [their] employees’. Section 5(a)(2) requires employers to ‘comply with occupational
safety and health standards promulgated under this Act’. The proposed project would be
required to provide training and equipment necessary to reduce exposure to acceptable
levels in accordance with federal OSHA and Cal-OSHA. As such, impacts related to the
worker exposure to toxic air contaminants during operation would be less than
significant.”
Likewise, the EIR contained a discussion of worker health and safety regulations,
which noted that worker health and safety was regulated by OSHA and Cal-OSHA; that

29
federal regulations required workers who came into contact with hazardous wastes to
receive specialized training and medical supervision; that California’s regulations for
workers dealing with hazardous material included specific practices for construction and
hazardous waste operation and emergency response, and that Cal-OSHA conducted on-
site evaluations and issued notices of violation to improve health and safety practices.
Plaintiffs contend this discussion was inadequate, and that the EIR was required to
make an independent evaluation of the effects of the project on workers’ health. We
disagree. An agency may properly rely on another agency’s regulatory scheme in
concluding an impact is less than significant. (See, e.g., Oakland Heritage Alliance v.
City of Oakland (2011) 195 Cal.App.4th 884, 903–904 [Building Code standards for
seismic safety]; Tracy First v. City of Tracy (2009) 177 Cal.App.4th 912, 930–934
[energy efficiency standards].) The EIR and responses to comments on the FEIR provide
substantial evidence to support the conclusion that the project would not cause significant
effects on worker health and safety.11
E. Brown Act
On October 12, 2010, the Board held a public meeting on Revised Project II, and
heard comments from the public. At the end of the hearing, the Board took a “straw
vote” on a motion to certify the EIR, adopt a statement of overriding considerations, and
approve the project with the conveyor option. The straw vote resulted in three votes in
favor of certification and approval, and two votes opposed. The Board continued the
matter for final approval until December 14, 2010 to allow County staff time to prepare
resolutions. At the December 14 meeting, the Board certified the EIR, adopted a
statement of overriding considerations and a mitigation monitoring program, and

Citing CEQA Guideline 15360, which defines “ ‘environment’ ” as “the
physical conditions which exist within the area which will be affected by a proposed
project including land, air, water, minerals, flora, fauna, ambient noise, and objects of
historic or aesthetic significance,” the trial court concluded CEQA does not require an
EIR to address worker health. We express no opinion on the propriety of this view, but
rather conclude that assuming CEQA encompasses worker safety, the EIR was not
inadequate for failing to address this issue further.

approved the project, general plan amendment, and rezoning.12 It appears that certain
documents were released to the public on the morning of the meeting. According to
plaintiffs, those documents included the conditions of approval of the project. The Board
did not allow additional public comments at the December 14 hearing.
Plaintiffs contend the Board violated the Brown Act by failing to allow further
public comments at the December 14, 2010 hearing. Government Code13 section
54954.3 provides in pertinent part: “Every agenda for regular meetings shall provide an
opportunity for members of the public to directly address the legislative body on any item
of interest to the public, before or during the legislative body’s consideration of the item
. . . . However, the agenda need not provide an opportunity for members of the public to
address the legislative body on any item that has already been considered by a committee,
composed exclusively of members of the legislative body, at a public meeting wherein all
interested members of the public were afforded the opportunity to address the committee
on the item, before or during the committee’s consideration of the item, unless the item
has been substantially changed since the committee heard the item, as determined by the
legislative body.”
The parties disagree on whether the Board violated this provision: according to
defendants, at the October 12, 2010 hearing when public comments were heard, the
Board was effectively acting as a “committee of the whole,” and therefore it was not
required to allow further public comments at the December hearing under section
54954.3. Plaintiffs, on the other hand, supported by amicus curiae John McGinnis, reject
the proposition that the Board acted as a committee at the October hearing, and contend

12
According to a resolution, the FEIR consisted of the DEIR, the responses to
comments circulated in July 2008, and three other documents: a January 19, 2009
response to a letter submitted by plaintiffs’ counsel and a summary report by the EIR
consultant, Christopher A. Joseph & Associates, and the September 24, 2010 summary
report on Revised Project II prepared by WRA.

All further undesignated statutory references are to the Government Code.

31
that its action in approving the project in December without hearing further public
comments should therefore be vacated.14
We need not resolve this issue, however, because we conclude that even if the
Board should have allowed further public comments at the December 14, 2010 meeting,
the remedy plaintiffs seek—a writ of mandate vacating the project approvals and related
decisions—is unavailable for a violation of the public comment requirement.
Section 54960.1, subdivision (a) provides in pertinent part: “The district attorney or any
interested person may commence an action by mandamus or injunction for the purpose of
obtaining a judicial determination that an action taken by a legislative body of a local
agency in violation of Section 54953, 54954.2, 54954.5, 54954.6, 54956, or 54956.5 is
null and void under this section.” Those sections establish requirements for local
legislative bodies’ meetings to be open and public (§ 54953), for agendas to be posted
before meetings (§ 54954.2), for descriptions of closed session items on agendas
(§ 54954.5), for meetings held before adoption of new or increased taxes or assessments
(§ 54954.6), for calling and providing notice of special meetings (§ 54956), and for
emergency meetings (§ 54956.5). Section 54954.3, which requires legislative bodies to

14
Defendants also contend we should not consider this issue because plaintiffs did
not raise it adequately before the Board or the trial court. We disagree. Before the
December 14, 2010 hearing, plaintiffs’ counsel sent a letter to the Board asserting that
section 54954.3, subdivision (a) required the Board to allow public comments. After the
hearing, they sent letters demanding that the Board cure the alleged Brown Act violation,
and pointing out that local agency representatives and members of the public were
precluded from addressing the Board at the December meeting. The County responded
by asserting that it had not violated the Brown Act, and quoted the portion of
section 54954.3, subdivision (a), that provides an exception for matters that had
previously been considered by a committee. In the trial court, plaintiffs asserted a cause
of action for violation of the Brown Act and alleged that defendants did not cite any
applicable exemption for statutory public hearing requirements, and argued in their
briefing below that the County violated the Brown Act by not allowing public comments
at the December meeting. Although plaintiffs never explicitly addressed below the
applicability of the “committee” exception of section 54954.3, subdivision (a), they
adequately preserved the issue of whether the County violated the Brown Act by refusing
to allow public comment at the December meeting.

provide an opportunity for public comment, is not among the provisions enumerated in
section 54960.1, subdivision (a).
Plaintiffs argue that nullification of the Board’s actions is nevertheless an
available remedy under the court’s general power to grant mandamus relief. (Code Civ.
Proc., § 1085.) In a similar argument, amicus curiae McGinnis contends this remedy is
authorized by another provision of the Brown Act, section 54960, which provides in
pertinent part: “The district attorney or any interested person may commence an action
by mandamus, injunction, or declaratory relief for the purpose of stopping or preventing
violations or threatened violations of this chapter by members of the legislative body of a
local agency or to determine the applicability of this chapter to ongoing actions or
threatened future actions of the legislative body . . . .”
We reject this contention. Under the principle of statutory construction that
expressio unius est exclusio alterius, or “ ‘to express or include one thing implies the
exclusion of the other,’ ” (Imperial Merchant Services Inc. v. Hunt (2009) 47 Cal.4th
381, 389) we conclude the Legislature intended to limit the remedy of declaring an
agency’s action null and void to violations of the enumerated statutory provisions. If the
Legislature had intended this remedy to be available for violations of any provision of the
Brown Act, its action in enumerating certain provisions in section 95460.1 would have
been superfluous. (See id. at p. 390.) The fact that the Legislature expressly designated
this remedy for violations of some provisions of the Brown Act indicates that it did not
intend nullification to be available as a remedy for violations of other portions of the
same statutory scheme.15

15
In any case, it appears that section 54960 applies primarily prospectively, that is,
that it applies to past violations only to the extent that “the showing of past violations that
was made related specifically to present or future ones.” (Shapiro v. San Diego City
Council (2002) 96 Cal.App.4th 904, 916, fn. 6.) Plaintiffs make no argument that any
alleged violation of the public comments requirement is related to a present or future
violation.
