I find that the proposed project COULD NOT have a significant effect on the
environment, and a NEGATIVE DECLARATION will be prepared.
I find that although the proposed project could have a significant effect on the
environment, there will not be a significant effect in this case because the mitigation
measures described on an attached sheet have been added to the project. A NEGATIVE
DECLARATION will be prepared.
I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
I find that the proposed project MAY have significant effect(s) on the environment, but at
least one potentially significant effect 1) has been adequately analyzed in an earlier
document pursuant to applicable legal standards, and 2) has been addressed by mitigation
measures based on the earlier analysis as described on attached sheets. An is required,
but it must analyze only the effects that remain to be addressed.
I find that although the proposed project could have a significant effect on the
environment, there WILL NOT be a significant effect in this case because all potentially
significant effects (a) have been analyzed adequately in an earlier MEIR pursuant to
applicable standards and (b) have been voided or mitigated pursuant to that earlier MEIR,
including revisions or mitigation measures that are imposed upon the proposed project.
Therefore, a Notice of Prior Compliance has been prepared.

ENVIRONMENTAL IMPACTS
STATE CEQA GUIDELINES, Chapter 3, Article 5, Section 15063 requires that the City
conduct an Environmental Impact Assessment to determine if a project may have a significant
effect on the environment. The Environmental Impact Assessment appears in the following
pages in the form of a checklist. This checklist identifies any physical, biological and human
factors that might be impacted by the proposed project and provides the City with information to
use as the basis for deciding whether to prepare an Environmental Impact Report (EIR), Negative
Declaration, or to rely on a previously approved EIR or Negative Declaration.
A brief explanation is required for all answers except ‘‘No Impact” answers that are
adequately supported by an information source cited in the parentheses following each
question. A “No Impact” answer is adequately supported if the referenced information
sources show that the impact simply does not apply to projects like the one involved. A
“NO Impact” answer should be explained when there is no source document to refer to, or
it is based on project-specific factors as well as general standards.
“Less Than Significant Impact” applies where there is supporting evidence that the
potential impact is not adversely significant, and the impact does not exceed adopted
general standards and policies.
“Potentially Significant Unless Mitigation Incorporated” applies where the incorporation
of mitigation measures has reduced an effect from “Potentially Significant Impact” to a
“Less Than Significant Impact.” The developer must agree to the mitigation, and the
City must describe the mitigation measures, and briefly explain how they reduce the
effect to a less than significant level.
“Potentially Significant Impact” is appropriate if there is substantial evidence that an
effect is significant,
Based on an “EIA-Part 11”, if a proposed project could have a potentially significant
effect on the environment, but Potentially significant effects (a) have been analyzed
adequately in an earlier EIR or Mitigated Negative Declaration pursuant to applicable
standards and (b) have been avoided or mitigated pursuant to that earlier EIR or Mitigated
Negative Declaration, including revisions or mitigation measures that are imposed upon
the proposed project, and none of the circumstances requiring a supplement to or
supplemental EIR are present and all the mitigation measures required by the prior
environmental document have been incorporated into this project, then no additional
environmental document is required (Prior Compliance).
When “Potentially Significant Impact” is checked the project is not necessarily required
to prepare an EIR if the significant effect has been analyzed adequately in an earlier EIR
pursuant to applicable standards and the effect will be mitigated, or a “Statement of
Overriding Considerations” has been made pursuant to that earlier EIR.
A Negative Declaration may be prepared if the City perceives no substantial evidence that
the project or any of its aspects may cause a significant effect on the environment.
3 Rev. 03/28/96
If there are one or more potentially significant effects, the City may avoid preparing an
EIR if there are mitigation measures to clearly reduce impacts to less than significant, and
those mitigation measures are agreed to by the developer prior to public review. In this
case, the appropriate “Potentially Significant Impact Unless Mitigation Incorporated”
may be checked and a Mitigated Negative Declaration may be prepared.
0 An EIR must be prepared if “Potentially Significant Impact” is checked, and including
but not limited to the following circumstances: (1) the potentially significant effect has
not been discussed or mitigated in an Earlier EIR pursuant to applicable standards, and
the developer does not agree to mitigation measures that reduce the impact to less than
significant; (2) a “Statement of Overriding Considerations” for the significant impact has
not been made pursuant to an earlier EIR; (3) proposed mitigation measures do not reduce
the impact to less than significant, or; (4) through the EIA-Part I1 analysis it is not
possible to determine the level of significance for a potentially adverse effect, or
determine the effectiveness of a mitigation measure in reducing a potentially significant
effect to below a level of significance.
A discussion of potential impacts and the proposed mitigation measures appears at the end of the
form under DISCUSSION OF ENVIRONMENTAL EVALUATION. Particular attention
should be given to discussing mitigation for impacts which would otherwise be determined
significant.

XVII. EARLIER ANALYSES.
Earlier analysis of the proposed infill single family development has been completed through the
General Plan Update (GPA 94-01)and related Master Environmental Impact Report (MEIR 93-
01). The MEIR is cited as source #1 in the preceding checklist. The proposal is consistent with
the applicable portions of the General Plan and is considered a Subsequent Project that was
described in the MEIR 93-01 as within its scope. There will be no additional significant effects
due to this development that were not analyzed in the MEIR and no new or additional mitigation
measures or alternatives are required. This Subsequent Project is, therefore, within the scope of
the prior EIR and no new environmental document nor Public Resources Code 21 081 findings
are required. All feasible mitigation measures or project alternatives identified in the MEIR 93-
01 which are appropriate to this Subsequent Project have been incorporated into this Subsequent
Project.
10 Rev. 03/28/96
DISCUSSION OF ENVIRONMENTAL EVALUATION
The proposed infill single family development is comprised of 3,700 cubic yards of grading on a
0.56 acre lot. All surrounding properties are developed and all public facilities have been
provided to the property. The 12,638 square foot house would take access off of Obelisco Place
and include private recreational facilities. The General Plan and Zoning Ordinance call for single
family development on the site and the proposal meets all applicable provisions of the Carlsbad
Municipal Code.
AIR QUALITY:
The implementation of subsequent projects that are consistent with and included in the updated
1994 General Plan will result in increased gas and electric power consumption and vehicle miles
traveled. These subsequently result in increases in the emission of carbon monoxide, reactive
organic gases, oxides of nitrogen and sulfur, and suspended particulates. These aerosols are the
major contributors to air pollution in the City as well as in the San Diego Air Basin. Since the
San Diego Air Basin is a “non-attainment basin”, any additional air emissions are considered
cumulatively significant: therefore, continued development to buildout as proposed in the
updated General Plan will have cumulative significant impacts on the air quality of the region.
To lessen or minimize the impact on air quality associated with General Plan buildout, a variety
of mitigation measures are recommended in the Final Master EIR. These include: 1) provisions
for roadway and intersection improvements prior to or concurrent with development; 2) measures
to reduce vehicle trips through the implementation of Congestion and Transportation Demand
Management; 3) provisions to encourage alternative modes of transportation including mass
transit services; 4) conditions to promote energy efficient building and site design; and 5)
participation in regional growth management strategies when adopted. The applicable and
appropriate General Plan air quality mitigation measures have either been incorporated into the
design of the project or are included as conditions of project approval.
Operation-related emissions are considered cumulatively significant because the project is
located within a “non-attainment basin”, therefore, the “Initial Study” checklist is marked
“Potentially Significant Impact”. This project is consistent with the General Plan, therefore, the
preparation of an EIR is not required because the certification of Final Master EIR 93-01, by City
Council Resolution No. 94-246, included a “Statement Of Overriding Considerations” for air
quality impacts. This “Statement Of Overriding Considerations” applies to all subsequent
projects covered by the General Plan’s Final Master EIR, including this project, therefore, no
further environmental review of air quality impacts is required. This document is available at the
Planning Department.
CIRCULATION:
The implementation of subsequent projects that are consistent with and included in the updated
1994 General Plan will result in increased traffic volumes. Roadway segments will be adequate
to accommodate buildout traffic; however, 12 full and 2 partial intersections will be severely
impacted by regional through-traffic over which the City has no jurisdictional control. These
generally include all freeway interchange areas and major intersections along Carlsbad
Boulevard. Even with the implementation of roadway improvements, a number of intersections
11 Rev. 03/28/96
are projected to fail the City’s adopted Growth Management performance standards at buildout.
To lessen or minimize the impact on circulation associated with General Plan buildout, numerous
mitigation measures have been recommended in the Final Master EIR. These include measures
to ensure the provision of circulation facilities concurrent with need; 2) provisions to develop
alternative modes of transportation such as trails, bicycle routes, additional sidewalks, pedestrian
linkages, and commuter rail systems; and 3) participation in regional circulation strategies when
adopted. The diversion of regional through-traffic from a failing Interstate or State Highway
onto City streets creates impacts that are not within the jurisdiction of the City to control. The
applicable and appropriate General Plan circulation mitigation measures have either been
incorporated into the design of the project or are included as conditions of project approval.
Regional related circulation impacts are considered cumulatively significant because of the
failure of intersections at buildout of the General Plan due to regional through-traffic, therefore,
the “Initial Study” checklist is marked “Potentially Significant Impact”. This project is
consistent with the General Plan, therefore, the preparation of an EIR is not required because the
recent certification of Final Master EIR 93-01, by City Council Resolution No. 94-246, included
a “Statement Of Overriding Considerations” for circulation impacts. This “Statement Of
Overriding Considerations” applies to all subsequent projects covered by the General Plan’s
Master EIR, including this project, therefore, no further environmental review of circulation
impacts is required.
