(a) An
EIR must include a description of the physical environmental conditions in the
vicinity of the project. This environmental setting will normally constitute
the baseline physical conditions by which a lead agency determines whether an
impact is significant. The description of the environmental setting shall be no
longer than is necessary to provide an understanding of the significant effects
of the proposed project and its alternatives. The purpose of this requirement
is to give the public and decision makers the most accurate and understandable
picture practically possible of the project's likely near-term and long-term
impacts.
(1) Generally, the lead agency
should describe physical environmental conditions 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. Where existing conditions change or fluctuate over
time, and where necessary to provide the most accurate picture practically
possible of the project's impacts, a lead agency may define existing conditions
by referencing historic conditions, or conditions expected when the project
becomes operational, or both, that are supported with substantial evidence. In
addition, a lead agency may also use baselines consisting of both existing
conditions and projected future conditions that are supported by reliable
projections based on substantial evidence in the record.
(2) A lead agency may use projected future
conditions (beyond the date of project operations) baseline as the sole
baseline for analysis only if it demonstrates with substantial evidence that
use of existing conditions would be either misleading or without informative
value to decision-makers and the public. Use of projected future conditions as
the only baseline must be supported by reliable projections based on
substantial evidence in the record.
(3) An existing conditions baseline shall not
include hypothetical conditions, such as those that might be allowed, but have
never actually occurred, under existing permits or plans, as the
baseline.
(b) When
preparing an EIR for a plan for the reuse of a military base, lead agencies
should refer to the special application of the principle of baseline conditions
for determining significant impacts contained in Section
15229.
(c) Knowledge of the regional setting is
critical to the assessment of environmental impacts. Special emphasis should be
placed on environmental resources that are rare or unique to that region and
would be affected by the project. The EIR must demonstrate that the significant
environmental impacts of the proposed project were adequately investigated and
discussed and it must permit the significant effects of the project to be
considered in the full environmental context.
(d) The EIR shall discuss any inconsistencies
between the proposed project and applicable general plans, specific plans and
regional plans. Such regional plans include, but are not limited to, the
applicable air quality attainment or maintenance plan or State Implementation
Plan, area-wide waste treatment and water quality control plans, regional
transportation plans, regional housing allocation plans, regional blueprint
plans, plans for the reduction of greenhouse gas emissions, habitat
conservation plans, natural community conservation plans and regional land use
plans for the protection of the coastal zone, Lake Tahoe Basin, San Francisco
Bay, and Santa Monica Mountains.
(e)
Where a proposed project is compared with an adopted plan, the analysis shall
examine the existing physical conditions at the time the notice of preparation
is published, or if no notice of preparation is published, at the time
environmental analysis is commenced as well as the potential future conditions
discussed in the plan.
