California Environmental
Quality Act
Principles and Process
City of Dublin Planning Commission
September 8, 2009
Presented by:
Kathleen Faubion, AICP, Of Counsel, Meyers Nave
&
Jaimee Bourgeois, PE, Senior Civil Engineer (Traffic)
2
Study Session Goals
Provide an overview of the principles
and processes of CEQA;
Role of CEQA in the decision making
process; and
Role of the Planning Commission in
CEQA
3
Purpose of CEQA Review
Inform decision makers and public
about environmental effects of
proposed activities.
Identify ways to avoid or reduce
environmental damage.
Prevent environmental damage
through mitigation or alternatives.
Disclose reasons agency approved
project with significant effects.
4
Implementation of CEQA
Purposes
Governmental action on proposed
projects:
Private projects that require
discretionary action
Public projects.
Planning Commission is part of CEQA
process as decision maker,
recommending body on private
projects, some public projects.
5
CEQA Applies to Approval of
“Projects”
Project: an activity undertaken by a public
agency, or, proposed by a person but
requires public agency approval, such as a
lease, permit or other entitlement.
Informed decision making: decision
makers should consider the environmental
consequences of approving and
implementing the project.
Lead Agency: public agency that carries
out or approves project, controls the
process, certifies compliance with CEQA.
6
Is the Project Exempt from
CEQA?
Statutory exemptions.
Categorical exemptions.
General or common sense exemption
under § 15061(b)(3) where it can be
seen with certainty that there is no
possibility that the activity may have
a significant effect on the
environment.
CEQA compliance complete upon
finding of exemption.
7
Activity is a “Project” and is
Not Exempt – What Next?
Complete an initial study checklist
questionnaire to determine whether the
project has the potential for significant
effects on the environment.
Will the project cause a change in the
environment?
Is the change significant?
Evaluate significance by comparing project
changes to thresholds of significance.
8
Initial Study Questionnaire Organized by
16 Resource Topic Areas
Aesthetics Geology/soils Noise
Agriculture Hazards/hazmat Population/housing
Air Quality Hydrology/water quality Public services
Biological resources Recreation Land use/planning
Cultural resources Mineral resources Transportation
Utilities
9
Thresholds of Significance
No single, correct threshold for the resource
areas; thresholds depend on nature of project,
circumstances, local priorities and policies.
Some thresholds contained in Initial Study
questionnaire:
Example: Will the project substantially alter existing
drainage patterns?
Regulatory standards may be used if appropriate:
Example: Will the project violate water quality
standards?
City practice is to develop thresholds for each
project review to retain flexibility.
Standards may be qualitative or quantitative
depending on the resource.
10
Initial Study Process May or May Not
Require Technical Reports to Evaluate
Potential Impacts
Commonly prepared technical
reports for Dublin projects:
Traffic
Aesthetics
Biology
Geology, hydrology
Noise
Preparing a technical report.
11
Start with a regional model developed at the County level that includes major roadway improvements and land development planned for within the region.
The model is calibrated and validated to replicate existing volumes within an allowable margin of error.
Using the regional model as a starting point, a City-wide model is created with more detailed roadway network and land use data within the City of Dublin and immediately surrounding areas.
The model is then ready to be executed to project future volumes.
Traffic Modeling
12
Project Trip Generation
The project trip generation is an estimate of the
number of trips (daily or peak hour) that the
project will generate.
An inbound and outbound trip each equal one
trip.
Trip generation rates developed from actual
surveys available in ITE’s Trip Generation and
SANDAG’s Traffic Generators.
When adequate published data is not available, it
will be necessary to collect new data at a similar
existing site or estimate trip generation based on
the characteristics of the proposed development.
13
Project Trip Generation (cont’d.)
Examples of various developments that
generate about 1,000 daily trips:
100 single family homes
150 apartments
20,000 square-foot shopping center
70,000 square-foot office building
14
Level of Service Analysis
The concept of level of service (LOS)
is commonly used to describe the
operating conditions of an intersection
or roadway segment.
The LOS grading system is a rating
scale ranging from LOS A to LOS F.
LOS A represents limited delay traffic
conditions and LOS F represents highly
congested conditions.
15
Level of Service Analysis
(cont’d.)
In Dublin, we utilize a vehicle delay-based
approach for determining LOS at
intersections according to procedures set
forth in the Transportation Research
Board’s Highway Capacity Manual (2000).
For a GPA and projects requiring an EIR, a
CMA Analysis of Metropolitan
Transportation System roadway segments
is required if the project generates 100 or
more PM peak hour trips.
16
Signalized Intersection LOS
Definitions
LOS Average Delay per Vehicle (seconds)
Description of Traffic Conditions
A ≤ 10 Very little delay; all waiting vehicles clear when the light is green
and many vehicles do not have to stop at all.
B >10 and ≤ 20 Little delay; most waiting vehicles clear when the light is green.
C >20 and ≤ 35 Noticeable delay; occasional congestion and backups on busy
approaches.
D
>35 and ≤ 55 Influence of congestion more noticeable; significant congestion of
busy approaches and vehicles could wait through more than one red
light during short periods but no excessive backups.
E >55 and ≤ 80
Significant congestion with long backups on busy approaches;
vehicles could wait up to several red lights; traffic backups may
interfere with nearby intersections; overall traffic demand is near
intersection capacity.
F > 80 Delay unacceptable to motorists; stop-and-go operation; overall
traffic demand exceeds intersection capacity.
17
Process for Completing a
Transportation Impact Analysis
The City commissions a traffic consultant to
complete the study, approves the scope of work,
and provides oversight of the study.
The study typically examines AM and PM peak
hour conditions for the following scenarios:
Existing Conditions
Existing + Project Conditions
Cumulative Without Project Conditions
Cumulative + Project Conditions
18
Process for Completing a Transportation Impact Analysis
(cont’d.)
The study might also examine midday or
weekend peak hour conditions depending on the
characteristics of the project and the local traffic
patterns.
Although not required by CEQA, the study might
also consider a near-term future scenario.
The impacts of the project on key intersections
and roadways are identified based on the
significance criteria.
Feasible mitigation measures are developed.
19
Significance Criteria
City of Dublin General Plan:
Requires that a good faith effort be made to
maintain LOS D on road segments and at
intersections located on Routes of Regional
Significance as established in the Tri-Valley
Transportation Plan and Action Plan.
Requires that for non-Routes of Regional
Significance, strive to maintain LOS D or
better.
20
Results of Initial Study
Prepare a Negative Declaration.
Prepare a Mitigated Negative
Declaration.
Prepare an Environmental Impact
Report.
21
Negative Declaration
Prepared when there is no
substantial evidence that a project
may have a significant effect on the
environment.
ND is a written statement of no
potential significant effect plus the
Initial Study providing evidence in
support.
22
Mitigated Negative Declaration
Prepared when a project may have a
significant effect on the environment
but measures are incorporated into
the project to mitigate the impact.
Measures must be agreed to by the
applicant.
Mitigated ND is also a written
statement of no potential significant
effect of the project, as mitigated,
plus the Initial Study providing
evidence in support.
23
Environmental Impact Report
Prepared when a project may have a
significant effect on the environment and
adequate mitigations were not identified
through the Initial Study process.
Fair argument standard applies to EIR
determination and creates a low threshold
favoring preparation of an EIR.
EIR process begins with Notice of Preparation
and initial scoping meeting to solicit guidance
from other agencies and the public as to the
scope and contents of a Draft EIR.
24
Environmental Impact Report
(cont’d.)
Draft EIR contains impact and
mitigation analysis for the resource
topics.
Draft EIR must identify a reasonable
range of project alternatives,
including No Project alternative.
25
Public Review and Comment
Period
CEQA requires a public review and
comment period for draft NDs and EIRs.
CEQA “notice” commences review and
comment period.
Time for public review period:
20-30 days for an ND
30-45 days for an EIR
Note: Caselaw provides that comments on
the draft ND or EIR can be submitted up
until the close of the public hearing on the
project, if any.
26
Responses to Comments Received
During the Public Review Period
ND or Mitigated ND: Responses to comments not required, but City may want to provide responses in particular situations.
Draft EIR: Written responses to comments are required. Comments and responses are compiled in a Final EIR.
Responses should dispose of the environmental issues raised in the comments and provide explanation where comments are at variance with lead agency position. Responses should provide good faith, reasoned analysis of issue supported by factual evidence.
No public review required for responses to comments.
27
Adopting the CEQA Document and
Approving the Project
Decisions and recommendations
should consider the environmental
consequences of the project, so…
CEQA action should be the first action.
CEQA findings may be required for
project approval.
28
CEQA Streamlining Techniques
CEQA encourages reuse of certified EIRs
or adopted NDs, MNDs.
Valuable tool for multi-layered land use
permit process:
Subsequent or supplemental ND or EIR allows
consideration of changes to original project.
Tiering allows consideration of more detailed
site or project information and design in later
steps of permitting process.
Addendum allows consideration of minor
changes that do not result in new or more
severe impacts than original ND or EIR.
29
CEQA Streamlining in Dublin
Large scale EIRs in Dublin facilitate streamlining.
Eastern Dublin EIR:
Certified in 1993 for 30 year buildout horizon.
Assumed urbanization of Eastern Dublin.
Comprehensive review based on additional detail in
EDSP.
Allows updating rather than new CEQA review for
many development projects that implement the
EDSP.
EDPO EIR, Fallon Village EIR, Transit Village EIR are
other examples.
30
Role of Planning Commission in
CEQA
Project is exempt: exemption determination
included in resolution approving project.
ND: Planning Commission reviews and adopts
ND before approving project:
Finding: a) There is no substantial evidence, in
light of the whole record, that the project may
have a significant effect on the environment,
and
b) The ND reflects the City’s independent
judgment and analysis.
31
Role of Planning Commission in
CEQA (cont’d.)
Mitigated ND: Planning Commission reviews MND and any comments received and adopts MND before approving project:
Finding: a) There are significant or potentially significant
effects identified for the project but revisions in the project
plans made by or agreed to by the applicant before the
proposed MND and initial study were released for public
review would avoid or mitigate to a point where clearly no
significant effects would occur, and
b) There is no substantial evidence, in light of the whole
record, that the project as revised may have a significant
effect on the environment, and
c) The Mitigated ND reflects the City’s independent judgment
and analysis.
MND also requires adoption of a Mitigation Monitoring and Reporting Program.
32
Role of Planning Commission in
CEQA (cont’d.)
When Planning Commission is
recommending body on a project, the
Commission considers the draft document
and recommends adoption of the ND, MND
or certification of the EIR to the Council.
Commission does not recommend on
mitigation monitoring program or other
CEQA findings that are required only if a
project is approved.
