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 II", if a proposed project could have a potentially significant effect on
the environment, but all 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.
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.
• 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 II 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.

Rev. 03/28/96
DISCUSSION OF ENVIRONMENTAL EVALUATION
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 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 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.
9 Rev. 03/28/96
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.
LAND USE AND PLANNING:
The project is the development of a 142 single family lot subdivision. Development will include the
construction of a portion of Cannon Road. The General Plan, Zoning, Local Coastal Program and a
Master Plan identify this site as a residential area for single family development. Cannon Road has
been included on the General Plan Land Use Map and in the General Plan text as a Major Arterial.
Development of the site will not be inconsistent with existing land use designations.
BIOLOGICAL RESOURCES:
The majority of the site has been disturbed and major portions of the road have been graded. Some
isolated vegetation exists interior to the site and a limited amount of significant plant community
exists within the Cannon Road right-of-way.
The interior vegetation is largely mixed chaparral. The pockets of chaparral are separated by graded
areas resulting in isolation from vegetated hillsides to the west and southwest. These interior
pockets are therefore not considered to have any significant biological value.
The plant communities found within the Cannon Road right-of-way have been identified in previous
studies as having significant biological value. Disturbance of these communities will require
mitigation if impacts are to be considered less than significant. Impacts to plant communities within
the Cannon Road right-of-way were identified in a report prepared by Tetra Tech, Inc. in January
1996. Direct impacts were identified as 0.16 acres of southern willow scrub; 0.14 acres of open
water; 0.13 acres of disturbed riparian scrub; 1.41 acres of coastal sage scrub; 0.51 acres of disturbed
coastal sage scrub; 0.14 acres of baccharis scrub; and 9.66 acres of disturbed area.
Specific mitigation measures for this disturbance have been identified and are included within the
Mitigation Measures section of this Environmental Impacts Assessment.
POPULATION AND HOUSING:
The City's Growth Management Plan and the General Plan make projections on housing and
population. The development of this area will only implement those plans which have determined
the maximum capacity for housing and population within the surrounding area. The development
itself will not be a contributor to increases in housing or population above what has already been
accounted for within the General Plan.
10 Rev. 03/28/96
GEOLOGIC:
There are no active faults identified within the limits of the City. Soils preparation for the
development will be per standard procedure which will reduce the potential for impacts to the road
once completed.
WATER:
The residential development of the site will not impact existing bodies of water other than the
bridging at the eastern edge of the project area for Cannon Road at El Camino Real. Standard
measures to implement the National Pollution Discharge Standards will capture harmful runoff from
the development prior to its discharge into Agua Hedionda Lagoon. Disturbance of open water, at
the bridge crossing, will require the issuance of an Army Corps of Engineers 404 permit.
ENERGY AND MINERAL RESOURCES:
No impacts have been identified.
HAZARDS:
No impacts have been identified.
NOISE:
Noise associated with the project will be created by vehicles traveling Cannon Road. A noise study
was prepared for the project. Mitigation measures have been incorporated into the project which
will reduce traffic related noise impacts on future residents to a level of less than significant.
Construction noise impacts can be reduced to levels of insignificance by scheduling work outside of
the breeding season.
PUBLIC SERVICES, UTILITIES AND SERVICE SYSTEMS:
The project is within the Zone 8 Local Facilities Management Plan. All services demanded by the
development of the project will be provided prior to or concurrently with development. No
significant impact has been identified.
AESTHETICS:
Development of the site has been proposed consistent with the regulations of the City's Hillside
Development Ordinance. The project occurs in an area that has been disturbed. Views of the site
are from the east. Because of the height of the hills east of the site, there will be no ridge line
disturbance. The road is designated to pass Agua Hedionda Lagoon on the south side. The road can
be designed to take advantage of the available views to the greatest extent possible.
CULTURAL RESOURCES:
Resources were identified onsite for the Kelly Ranch when an EIR was prepared in 1983. Those
resources were recovered through a data recovery program. No further known resources are onsite.
There will not be any significant impact to cultural resources.
11 Rev. 03/28/96
RECREATION:
Individual recreation lots are proposed within the subdivision. The development of the site will not
preclude community recreational resources. No impact has been identified.
ALTERNATIVES:
Project alternatives are required when there is evidence that the project will have a significant
adverse impact of the environment and an alternative would lessen or mitigate those adverse
impacts. Public Resources Code section 21002 forbids the approval of projects with significant
adverse impacts when feasible alternatives or mitigation measures can substantially lessen such
impacts. A "significant effect" is defined as one which has a substantial adverse impact. Mitigation
measures required as conditions of project approval will reduce the identified potentially significant
impacts to insignificant levels; therefore, no discussion of alternatives is necessary.

LIST OF MITIGATING MEASURES CIF APPLICABLE)
Direct Impacts from Cannon Road
1. Impacts to coastal sage scrub habitat shall be mitigated either through the City's HMP 4D
process, or through a separate Section 7 consultation with the USFWS. Mitigation may
include revegetation of a particular suitable area or the purchase of habitat in a mitigation
bank within the City of Carlsbad.
2. Impacts to regenerating disturbed coastal sage scrub may be considered significant and will
be mitigated by the same method and at the same rate as coastal sage scrub habitat.
3. The intersection of Cannon Road and El Camino Real necessitates a bridge across Agua
Hedionda Creek. This will impact southern willow riparian scrub, open water, and disturbed
riparian scrub. Southern willow scrub is a no net loss habitat and mitigation will be required
at a ratio of at least 2:1. Prior to the issuance of a grading permit, a 404 permit will be
required from the USAGE and a Streambed Alteration Agreement pursuant to 1601 will be
required from the CDFG.
Indirect Impacts from Cannon Road
4. The right-of-way for Canon Road should be clearly flagged, staked and fenced prior to
initiation of clearing, grubbing, or grading. The right-of-way should be fenced with a visual
barrier such as a drift fence. The purpose of the barrier is to protect the adjacent habitat
during construction. This includes protection of coastal sage scrub habitat as well as the
riparian habitats associated with the Agua Hedionda Creek. The right-of-way does not need
to be flagged or fenced on the south side except where it is adjacent to native habitat. The
placement of the fencing should be based on survey stakes at the site and not on the
biological resource maps.
5. Initiation of construction should occur outside of the least Bell's vireo breeding and nesting
season (May 15 through July 15). If this is not possible, a qualified biologist should survey
the areas that occur in or near the southern willow scrub habitat, prior to construction. If the
least Bell's vireo is not observed within the habitat, then construction can be initiated.
6. Storm water runoff should be directed into an oil separator and/or desiltation basin. This will
ensure protection of off-site resources in the Agua Hedionda Creek and the lagoon
downstream.
7. Indirect impacts to nesting birds can be avoided by initiating construction in late summer,
fall, or winter. If this is not possible, then a nesting bird survey may need to be conducted
prior to brushing, clearing, or grading.
Geology/Soils
8. Detailed geotechnical and soils studies will be prepared and engineering solutions approved
by the City prior to development. Erosion control measures will be required during project
construction.
9. Further slope stability investigations will be conducted. Any unfavorable conditions will be
removed or stabilized by buttressing or reorientation of slope direction.

A runoff control plan will be prepared which demonstrates that there will be no significant
increase in peak runoff rate from the development site over the greatest discharge expected
from the existing undeveloped site as from a 6-hour, 10-year frequency storm.
Vr
Development approvals shall include detailed provisions for emplacement, repair and
maintenance of approved drainage and erosion facilities. Permanent runoff and erosion
control devices shall be installed prior to or concurrent with onsite grading activities.
Noise barriers shall be provided along Cannon Road and El Camino Real frontages as
described in TABLE S-l of "Exterior Noise Analysis for Kelly Ranch Area E" prepared by
Mestre Greve Associates; Report # 96-173 Dated November 19, 1996.

Mitigation Measure
The intersection of Cannon Road and El Camino Real
necessitates a bridge across Agua Hedionda Creek. This
will impact southern willow riparian scrub, open water, and
disturbed riparian scrub. Southern willow scrub is a no
net loss habitat and mitigation will be required at a ratio of
at least 2:1. Prior to the issuance of a grading permit, a
404 permit will be required from the USAGE and a
Streambed Alteration Agreement pursuant to 1601 will be
required from the CDFG.
The right-of-way for Canon Road should be clearly
flagged, staked and fenced prior to initiation of clearing,
grubbing, or grading. The right-of-way should be fenced
with a visual barrier such as a drift fence. The purpose of
the barrier is to protect the adjacent habitat during
construction. This includes protection of coastal sage
scrub habitat as well as the riparian habitats associated
with the Agua Hedionda Creek. The right-of-way does not
need to be flagged or fenced on the south side except
where it is adjacent to native habitat. The placement of
the fencing should be based on survey stakes at the site
and not on the biological resource maps.

Mitigation Measure
Initiation of construction should occur outside of the least
Bell's vireo breeding and nesting season (May 15 through
July 15). If this is not possible, a qualified biologist should
survey the areas that occur in or near the southern willow
scrub habitat, prior to construction. If the least Bell's vireo
is not observed within the habitat, then construction can
be initiated.
•storm water runoff should be directed into an oil separator
! and/or desiltation basin. This will ensure protection of off-
site resources in the Agua Hedionda Creek and the
lagoon downstream.
Indirect impacts to nesting birds can be avoided by
initiating construction in late summer, fall, or winter. If this
is not possible, then a nesting bird survey may need to be
conducted prior to brushing, clearing, or grading.
Detailed geotechnical and soils studies will be prepared
and engineering solutions approved by the City prior to
Development. Erosion control measures will be required
during project construction.
Further slope stability investigations will be conducted.
Any unfavorable conditions will be removed or stabilized
by buttressing or reorientation of slope direction.

Mitigation Measure
A runoff control plan will be prepared which demonstrates
that there will be no significant increase in peak runoff
rate from the development site over the greatest
discharge expected from the existing undeveloped site as
from a 6-hour, 10-year frequency storm.
Development approvals shall include detailed provisions
wor emplacement, repair and maintenance of approved
Wrainage and erosion facilities. Permanent runoff and
erosion control devices shall be installed prior to or
concurrent with onsite grading activities.
Noise barriers shall be provided along Cannon Road and
El Camino Real frontages as described in TABLE S-1 of
"Exterior Noise Analysis for Kelly Ranch Area E" prepared
by Mestre Greve Associates; Report # 96-173 Dated
November 19, 1996.
