(To be completed by the Lead Agency)
I find that the proposed project COULD NOT have a significant effect on the
environment, and a NEGATIVE DECLARATION will be prepared.
c] 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.
0 I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
0 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 EIR/Neg Dec
is required, but it must analyze only the effects that remain to be addressed.
0 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 EIR/Neg Dec pursuant
to applicable standards and (b) have been voided or mitigated pursuant to that earlier
EIR/Neg Dec, including revisions or mitigation measures that are imposed upon the
proposed project. Therefore, a Notice of Prior Compliance has been prepared.

I. ENVIRONMENTAL IMPACTS
STATE CEQA GUIDELINES, Chapter 3, Article 5, Section 15063
conduct an Environmental Impact Assessment to determine if a project
requires that the City
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.
8 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.
e “Potentially Significant Impact” is appropriate if there is substantial evidence that an
effect is significant.
e 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).
e 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.
e 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
I.
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.
e 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.

Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA
process, one or more effects have been adequately analyzed in an earlier EIR or negative
declaration. Section 15063(c)(3)(D). In this case a discussion should identify the
following on attached sheets:
a) Earlier analyses used. Identifjl earlier analyses and state where they are available
for review.
b) Impacts adequately addressed. Identifjl which effects from the above checklist
were within the scope of and adequately analyzed in an earlier document pursuant
to applicable legal standards, and state whether such effects were addressed by
mitigation measures based on the earlier analysis.
c) Mitigation measures. For effects that are “Less than Significant with Mitigation

.. DISCUSSION OF ENVIRONMENTAL EVALUATION
The subject site is located within an existing 20-lot industrial located along Palomar Oaks Way.
Eighteen of the 20 lots have been developed with industrial land uses. This subdivision, located
along Palomar Oaks Way, was created by Tentative Tract Map CT 80-38 and Planned Unit
Development PUD 22. Palomar Oaks Architectural. Development and Maintenance Standards,
administratively approved, regulates development within the industrial park. The subject
amendment proposes minor revisions to which update the document to better reflect Planned
Industrial Zone standards as well as existing development. Revisions include amendment of the
plan review process to require the processing of a planned industrial permit for future
development and a modification eliminating the requirement for landscaping of interior side and
rear yard setbacks to more accurately reflect existing conditions and the pattern of development
that has occurred over the years. Through a planned industrial permit, the applicant is also
proposing to add 1,440 square feet to an existing 62,357 light industrial building and to enclose
an outdoor mechanical equipment area. This action is considered exempt from further
environmental review per Section 15301(e)(2) of CEQA and therefore, is not discussed further.
Due to the nature of this project and its location, the following EIA Part I1 Checklist categories
have been fully addressed within other documents which have been cited. No further discussion
is required.

IV. WATER
The proposed changes to the PUD are text changes only related to utilization of setbacks as well
as the requirement for a Planned Industrial Permit. As such, these revisions will not result in
development itself but will instead regulate development. Future projects will require individual
project review with regard to impacts to water. The proposed text changes will not result in
changes in absorption rates, drainage patters, or the rate and amount of surface runoff. Since no
major physical development is proposed with this project, there will no exposure of people or
property to flooding, no discharge into or changes to surface water, or water currents.
AIR OUALITY:
a. 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.
10 Rev. 03/28/96
I
I
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
(2) measures to reduce vehicle trips through the implementation of Congestion and
(3) provisions to encourage alternative modes of transportation including mass transit
(4) conditions to promote energy efficient building and site design; and
(5) participation in regional growth management strategies when adopted.
development;
Transportation Demand Management;
services;
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
z!.pproval.
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 93-0 1, 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.
b. There is no evidence that there are sensitive receptors (people susceptible to respiratory
distress) proposed as part of the project.
c. Experience has shown that typical industrial buildings in the City will not have an effect
on the movement of air or cause a change in climate.
d. The project description has not identified any use within the proposed building which
would create objectionable odors.
TRANSPORTATION/CIRCULATION:
a. 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 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
11 Rev. 03/28/96
CL
i
..
-5 include:
(1) 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 Wher environmental review of circulation impacts is required.
b. The project has been designed consistent with the design guidelines for PUD 22. No
changes have been made that would create conflict or safety hazards.
d. Parking has been provided according to the standards identified in the Carlsbad Parking
Ordinance and/or the provisions of PUD 22.
f. Palomar Airport Road has bike lanes and a bus route that are convenient to the project.
g. The proposed project complies with the McClellan-Palomar Airport Comprehensive Land
Use Plan regarding location of buildings relative to air traffic. No conflict has been
identified.
IX. NOISE:
The proposed revisions to the regulatory design guidelines and development standards approved
in conjunction with PUD 22 include noise provisions to ensure a maximum 60db(A). Noise
emanating from outdoor equipment, which is operated on a 24-hour basis, currently measures
from 81 dBA at scrubber FS-4 to 65 dBA opposite scrubber FS-5. This is above the 61 dBA (or
65 Ldn) maximum allowed by the Zoning Ordinance or the 60dBA permitted by the design
guidelines. Noise mitigation measures have been included at the end of this document to reduce
noise levels to permitted levels. These measures include:
12 Rev. 03/28/96
.- (1) the addition of an Industrial Acoustics type 7L silencer to the Greenheck exhaust fan on
scrubber FS-4;
equipment area;
proposed mitigation measures; and
equipment area without.
(2) the construction of an Empire Acoustical Systems sound barrier screen wall around the
(3) submittal of a final noise survey by the acoustical consultant to determine compliance with
(4) restrictions prohibiting the placement of additional equipment within the existing
Implementation of these measures will reduce noise levels to 59 dBA thereby eliminating any
adverse environmental impacts related to noise.
XIV. CULTURAL RESOURCES
The 20-lot subdivision has been previously graded and was found not to impact any cultural
resources. No grading is proposed at the present time either through the minor expansion of the
Air Chemicals and Products facilities or the text changes to the design guidelines. Development
of the two remaining lots will include environmental review at the time development is
proposed; however, indications fiom the prior tentative maps and environmental review indicate
no likelihood of cultural resources on these sites. This includes paleontological, archaeological,
or historical resources.
XVI. MANDATORY FINDINGS OF SIGNIFICANCE:
See the discussion under Air Quality and Traffic/Circulation.
XVII. EARLIER ANALYSES:
This project site is within a planned industrial park which was analyzed in an earlier
environmental review (Negative Declaration). The current project is consistent with the site
development as originally anticipated and analyzed in that Negative Declaration.
