NOTICE OF INTENT TO ADOPT A
MITIGATED NEGATIVE DECLARATION
CASE NAME: ST. CLAIRE RESIDENCE
CASE NO: CDP 02-24/SDU 02-23
PROJECT LOCATION: West side of Adams Street, south of Park Drive (APN 206-192-38)
PROJECT DESCRIPTION: Request for approval of a Coastal Development Permit and
Second Dwelling Unit Permit for the construction of a single-family residence and attached
second dwelling unit.
PROPOSED DETERMINATION: The City of Carlsbad has conducted an environmental
review of the above described project pursuant to the Guidelines for Implementation of the
California Environmental Quality Act and the Environmental Protection Ordinance of the City of
Carlsbad. As a result of said review, the initial study (EM Part 2) identified potentially
significant effects on the environment, but (1) revisions in the project plans or proposals made
by, or agreed to by, the applicant before the proposed negative declaration and initial study are
released for public review would avoid the effects or mitigate the effects to a point where clearly
no significant effect on the environment would occur, and (2) there is no substantial evidence in
light of the whole record before the City that the project "as revised" may have a significant
effect on the environment. Therefore, a Mitigated Negative Declaration will be recommended
for adoption by the City of Carlsbad Planning Director.
A copy of the initial study (EIA Part 2) documenting reasons to support the proposed Mitigated
Negative Declaration are on file in the Planning Department, 1635 Faraday Avenue, Carlsbad,
California 92008. Comments from the public are invited. Please submit comments in writing to
the Planning Department within 30 days of the date of this notice.
The proposed project and Mitigated Negative Declaration are subject to review and
approvaVadoption by the City of Carlsbad Planning Commission and City Council. Additional
public notices will be issued when those public hearings are scheduled. If you have any
questions, please call Barbara Kennedy in the Planning Department at (760) 602-4626.

DETERMINATION: The City of Carlsbad has conducted an environmental review of the above described
project pursuant to the Guidelines for Implementation of the California Environmental Quality Act and the
Environmental Protection Ordinance of the City of Carlsbad. As a result of said review, the initial study
(EL4 Part 2) identified potentially significant effects on the environment, and the City of Carlsbad finds as
follows:
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.
0 The proposed project MAY have “potentially significant impact(s)” on the environment, but at least
one potentially significant impact 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. (Mitigated Negative Declaration applies only to the effects
that remained to be addressed).
[7 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 ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION
pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier
ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION, including revisions or
mitigation measures that are imposed upon the proposed project. Therefore, nothing Mer is
required.

MAY 13,2003 ADDENDUM
EIA FOR CDP 02-24 - ST. CLAIRE RESIDENCE
The California Environmental Quality Act (CEQA) Section 15074.1 and Section 15073.5
addresses the circumstances under which substitution of mitigation measures in a proposed
Mitigated Negative Declaration (MND) can occur and when re-circulation of a proposed MND is
required. Pursuant to these sections, mitigation measures may be substituted or added which will
avoid or reduce the significant effect to at least the same degree as, or to a greater degree than the
original measure and will create no more adverse effect of it’s own than would the original
measure. No re-circulation of the proposed MND is required when 1) Mitigation measures are
replaced with equal or more effective measures pursuant to Section 15074.1; 2) New project
revisions are added in response to written or verbal comments on the project’s effects identified
in the proposed MND which are not new avoidable significant effects; 3) Measures or conditions
of project approval are added after circulation of the MND which are not required by CEQA,
which do not create new significant environmental effects and are not necessary to mitigate an
avoidable significant effect; and 4) New information is added to the MND which merely
clarifies, amplifies, or makes insignificant modifications to the MND.
This addendum is in response to a joint comment letter from USFWS and CDFG received on
May 5, 2003, which is attached for reference to this addendum. New information is included
which clarifies and responds to the comment letter and additional mitigation measures are
included as follows:
1. Reswonse: The biological report submitted for the project analyzed both the subject
parcel and the parcel immediately adjacent to the north. The report indicates that
approximately 100+ individual plants of summer holly occur on this site and 200+
individual plants occur on the adjacent site. The report firther states that
approximately 50 individual plants would be directly impacted within the 50’ brush
management zone (total for both parcels). According to a follow-up conversation
with the biologist, there is an even distribution of the impacted summer holly between
the two parcels. Therefore, approximately 25 of the loo+ individual plants would be
impacted which would result in conservation of over 75% of summer holly on the
subject site, consistent with the goals and conservation measures under the draft
HMP. No additional mitigation required.
2. Response: The Mandatory Finding of Significance statement of the MND stating
“the project does not contain any fish or wildlife species.” is a typographical error and
should read “The site does not contain any fish or simificant wildlife species.” The
CSS habitat in this location is an isolated parcel surrounded by residential
development. The biological report prepared for the project states that regionally,
CSS provides habitat for numerous sensitive plant and wildlife species. Animals
confined primarily to this habitat include California gnatcatcher, cactus wren, orange-
throated whiptail, and San Diego homed lizard. The CSS habitat in this location
likely does not function as a habitat corridor due to its lack of connectivity at its
northern and southern termini. The habitat may act as a linkage, owing to its
geographical proximity to Agua Hedionda Lagoon, providing a stepping stone for
species dispersal. A Gnatcatcher Field Survey was conducted for the site and no
1
Gnatcatchers were detected. The biology report states that because of the geographic
position of the site in the context of surrounding development and the dominance of
steep slopes, it is unlikely that the property receives significant use from larger
mammals such as mule deer, coyote, and bobcat.
The project will impact 0.116 of the 0.36 acres of CSS and impacts will be mitigated
through conservation of 67% (0.244 acres) of CSS, consistent with the City’s draft
HMP. A subsequent Gnatcatcher survey will be conducted prior to grading to
mitigate potential disturbances to breeding pairs. If active nests are found, no grading
or removal of habitat may take place within 200 feet of active nesting sites during the
nestinghreeding season. With these mitigation measures in place, the project does
not have the potential to degrade the quality of the environment, substantially reduce
the habitat of a fish or wildlife species, cause a fish or wildlife population to drop
below self-sustaining levels, threaten to eliminate a plant or animal community,
reduce the number or restrict the range of a rare or endangered plant or animal or
eliminate important examples of the major periods of California history or prehistory.
Given the above discussion, City staff and the project biologist agreed that a
zoological study was not required since the site is a small isolated pocket of
vegetation surrounded on all sides by residential development. The Wildlife
Agencies are requesting a general zoological survey of the site. In follow-up
conversation with John Martin, USFWS, this survey can be performed prior to
issuance of a de minimis permit for take of CSS habitat from the Wildlife Agencies, if
after further review and discussion, it is still required by the Wildlife Agencies.
3. Response: The originally proposed mitigation measures require a qualified biologist
to survey the site prior to commencement of grading activities to locate active
gnatcatcher nests. If nests are present, no grading or removal of habitat may take
place within 200 feet of active nests during the Gnatcatcher breeding season. The
requested mitigation measures would restrict clearing and grubbing in existing
vegetation during the bird breeding season whether Gnatcatchers were observed or
not, to avoid impacts to other nesting migratory birds. This condition would only
affect clearing and grubbing necessary for grading and thinning of the fire
suppression zone, not the actual grading operation itself.
The second request would require noise attenuation of construction activities (grading
and building) only if active Gnatcatcher nests are found within a distance that would
be affected by noise from these activities. Mitigation measures will be included.
4. Resvonse:
included.
Mitigation measure requiring shielding of outdoor lighting will be
5. Response: Mitigation measure requiring the use of native plants, to the greatest
extent feasible, in the landscape areas adjacent to and/or near the mitigationlopen
space areas will be included.

Re: Comments on the Mitigated Negative Declaration for the St. Claire Residence Project in
the City of Carlsbad, San Diego County, California
Dear Ms. Kennedy:
The California Department of Fish and Game (Department) and U. S. Fish and Wildlife Service
(Service) (collectively, “Wildlife Agencies”) have reviewed the above-referenced mitigated
negative declaration (MND), dated April 4,2003 and received on April 2,2003. The Wildlife
Agencies have identified concerns regarding the potential effects of this project on wildlife and
regional conservation planning. The comments provided herein are based on the information
provided in the MND; the Results of a California Gnatcatcher Field Survey for the Adams Street
Single Family Residence (SFR) Project, prepared by Vince Scheidt and dated April 18,2001; the
Updated Biological Resources Impact Assessment for the Adams Street Residential Parcels 206-
192-34 and 206-192-38, City of Carlsbad, San Diego County, California, prepared by Jeff L.
Thomas and dated October 24,2002; addenda to the Biological Resources Impact Assessment,
also prepared by Mr. Thomas and dated November 15,2002 and January 14,2003; the Wildlife
Agencies’ knowledge of sensitive and declining vegetation communities in San Diego County
(County); and our participation in regional conservation planning efforts,
.
The primary concern and mandate of the Service is the protection of public fish and wildlife
resources and their habitats. The Service has legal responsibility for the welfare of migratory
birds, anadromous fish, and endangered animals and plants occurring in the United States. The
Service is also responsible for administering the Endangered Species Act of 1973, as amended
(Act) (16 U.S.C. 1531 et seq.). The Department is a Trustee Agency and a Responsible Agency
pursuant to the California Environmental Quality Act (CEQA) and is responsible for ensuring
appropriate conservation of fish and wildlife resources including rare, threatened, and
endangered plant and animal species, pursuant to the California Endangered Species Act
(CESA). The Department also administers the Natural Community Conservation Planning
(NCCP) program. The City of Carlsbad (City) is currently participating in the NCCP program
through the preparation of a draft Multiple Habitat Conservation Program Habitat Management
Plan (HMP).
Ms. Barbara Kennedy (FWS-SDG-3482.1) 2
The proposed project is the construction of a dehched single-family home and attached second
dwelling unit on an 0.64-acre site (parcel 206-192-38) in the City. The project site is located
west of the intersection of Park Drive and Adams Street, approximately 280 yards from the north
shore of Agua Hedionda Lagoon. A strip of native habitat, approximately 150 to 300 feet wide
by 1,500 feet long, runs north to south and includes habitat in the western side of the project site.
Residential development surrounds the strip of native habitat and exists north and east of the
project site.
Mr. Thomas’ January 14,2003 revised addendum to the Updated Biological Resources Impact
Assessment identifies the following vegetative communities on-site: 0.36 acre of Diegan coastal
sage scrub (CSS), 0.06 acre of developed land, and 0.22 acre of ruderal land. Surveys for coastal
California gnatcatcher (Polioptila califomica califarnica; gnatcatcher), conducted in February
and March 200 1 , were negative. Approximately 100 individual California adolphia (Adolphia
califomica) and 100 individual summer holly (Comarostaphylis diversifolia) were found on the
project site.
According to the MND, the proposed development would directly impact approximately 0.166
acre of CSS, all of the ruderal land, 50 California adolphia, and 50 summer holly. To mitigate
impacts to CSS, the applicant proposes to conserve 0.244 acres of CSS on-site in an open space
easement.
The Wildlife Agencies offer our recommendations and comments to help the City adequately
analyze and mitigate potentially significant project impacts to biological resources pursuant to
CEQA, and ensure that the project is consistent with ongoing regional habitat conservation
planning efforts. We have the following concerns about the proposed project as described in the
MND:
1. The CEQA Guidelines, Section 15070, establish criteria for which an MND may be
prepared, including: “...There is no substantial evidence, in light of the whole record
before the agency, that the project as revised may have a significant effect on the
environment.” Although the project may have been revised to avoid a portion of the
sensitive plants on-site, we reconmend that the project minimize impacts to summer
holly and be consistent with the conservation goals and measures for species proposed for
coverage under the draft HMP. The draft HMP states that at least 75 percent of the major
population of summer holly in the vicinity of Agua Hedionda Lagoon will be conserved,
yet only half of the individual summer holly on-site are proposed to be conserved.
Increasing the conservation from 50 percent to 75 percent would substantially improve
the species’ conservation on-site.
2. The October 24,2002 Updated Biological Resources Impact Assessment states that
“expected wildlife use of the site was not formally determined and site specific wildlife
surveys were not conducted...”, yet the Mandatory Findings of Significance section of the
Initial Study Checklist for the MND states that, ‘The project site does not contain any fish
or wildlife species. Therefore, the project will not reduce the habitat of a fish or wildlife
species.” Before the MND is finalized, please clarify this discrepancy and provide us
with a list of species with the potential to occur on-site and the results of a general
zoological survey of the site.
Ms. Barbara Ktnotdy (PWS-SDQ-3482.1) 3
3. We recommend that all clearing and grubbing in existing vegetation avoid &e bird
breeding season (Febxuary 15 to August 31), in order to avoid take of migratory birds.
Nesting birds and their young are susceptible to impacts from clearing, grubbing, grading,
or other constmction activity. Nesting birds include those that have nests with eggs,
juveniles (nestlings), and dependemt juveniles of limited mobility (fledglings). In addition
prior to construction activities, a qualified biologist should survey the habitat areas
adjacent to the project site to determine if any gnatcatcher nests are within a distance
potentially affected by noise from these activities; If no nesting gnatcatchers are located,
no additional rnwwes will need to be taken to mitigate indirect impacts. However, if
nesting gnatcatchers a= observed, no activity will OCCUT without noise attenuation (e.g.,
noise baniem) to ens= that noise levels within occupied gnatcatcher habitat do not
exceed 60 dBA Lq,
4. In order to reduce the potential for indirect lighting effectsfrom the proposed project, we
recommend that all outdoor lighting be shielded and directed away from the open space.
5. The Wildlife Agencies recommend the use of native plants to the greatest extent feasible
in the landscape anm adjacent to andlor near mitigatiodopen space areas. The applicant
should not plant, seed or otherwise inoroduce invasive exotic plant species to the
landscaped area3 adjacent and/or near the mitigatidopen space area. Exotic plant
species not to be used include those species listed on fists A & B of the California Exotic
Pest Plant Council's list of "Exotic Pest Plants of Greatest Ecological Concern in
California RS of October 1999." This list includes such species as: pepper trees, pampas
grass, fountain grass, ice plant, rnyoporum, black locust, capewaxl, tree of heaven,
periwinkle, sweet alyssum, Enghsh ivy, French broom, Scotch broom, and Spanish
broom. A copy of the complete list can be obtained by contacting the California Exotic
Pest Plant Council at 32912 Calle del Tesm, San Juan Capistrano, California
-
926754427, or by accessing their web site at .o .
The Wildlife Agencies appreciate the opportunity to comment on the St. Claire MND and are
available to work with the City, the applicant, and their consultants to address our concern.
Please contact John Martin of the Service at (760) 431-9440 or Nancy Froat of the Department at
(858) 637-55 11, if you have any questions or comments concerning this letter.

DETERTvUNATION.
(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.
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 MITIGATED NEGATIVE DECLARATION will be prepared.
I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMF'ACT REPORT is required.
I find that the proposed project MAY have "potentially significant impact(s)" on the environment, but at
least one potentially significant impact 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. A Negative Declaration 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 ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION
pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier
EWONMENTAL IMPACT REPORT or NEGATIVE DECLARATION, including revisions or
mitigation measures that are imposed upon the proposed project. Therefore, nothing further is required.

ENVTRONMENTAL 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 significantly adverse, 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
significantly adverse.
Based on an “EM-Part II”, if a proposed project could have a potentially significant adverse
effect on the environment, but potentially significant adverse 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.
When “Potentially Significant Impact” is checked the project is not necessarily required to
prepare an EIR if the significant adverse 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 adverse effect on the environment.
If there are one or more potentially significant adverse effects, the City may avoid preparing an
EIR if there are mitigation measures to clearly reduce adverse 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.
4 Rev. 07/03/02
a An EIR be prepared if “Potentially Significant Impact” is checked, and including but not
limited to the following circumstances: (1) the potentially significant adverse 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 adverse impact to less than significant; (2) a
“Statement of Overriding Considerations” for the significant adverse impact has not been made
pursuant to an earlier EIR, (3) proposed mitigation measures do not reduce the adverse impact to
less than significant; or (4) through the EIA-Part 11 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.

DISCUSSION OF ENVIRONMENTAL EVALUATION
# AESTHETICS
No Impact. The project will have not have a substantial adverse effect on a scenic vista since the site is
located in an existing residential area and will be constructed in compliance with the maximum 30’ height
limitation allowed in the R-1-15,000 zone. Development of the site with a single family residence and
attached second dwelling unit would be consistent with the surrounding development pattern.
AGRICULTURAL RESOURCES
No Impact. There will be no impact on agricultural resources due to the proposed project as the site is
not designated as or used as farmland. The subject site is zoned for single-family residential projects (R-
1-15,000) and is not subject to a Williamson Act Contract. The project would not result in other changes
to the environment that would result in the conversion of farmland to non-agricultural uses. The project
would be characterized as infill development and has been surrounded by residential development for
many years.
AIR QUALITY-Would the project:
a) Conflict with or obstruct implementation of the applicable air quality plan?
No Impact. The project site is located in the San Diego Air Basin which is a federal and state non-
attainment area for ozone (03), and a state non-attainment area for particulate matter less than or equal to
10 microns in diameter (PM,,,). The periodic violations of national Ambient Air Quality Standards
(AAQS) in the San Diego Air Basin (SDAB), particularly for ozone in inland foothill areas, requires that
a plan be developed outlining the pollution controls that will be undertaken to improve air quality. In San
Diego County, this attainment planning process is embodied in the Regional Air Quality Strategies
(RAQS) developed jointly by the Air Pollution Control District (APCD) and the San Diego Association
of Governments (SNAG).
A plan to meet the federal standard for ozone was developed in 1994 during the process of updating the
1991 state-mandated plan. This local plan was combined with plans from all other California non-
attainment areas having serious ozone problems and used to create the California State Implementation
Plan (SIP). The SIP was adopted by the Air Resources Board (ARB) after public hearings on November
9th through 10th in 1994, and was forwarded to the Environmental Protection Agency (EPA) for
approval. After considerable analysis and debate, particularly regarding airsheds with the worst smog
problems, EPA approved the SIP in mid-1996.
The proposed project relates to the SIP and/or RAQS through the land use and growth assumptions that
are incorporated into the air quality planning document. These growth assumptions are based on each
city’s and the County’s general plan. If a proposed project is consistent with its applicable General Plan,
then the project presumably has been anticipated with the regional air quality planning process. Such
consistency would ensure that the project would not have an adverse regional air quality impact.
.
Section 15125(B) of the State of California Environment Quality Act (CEQA) Guidelines contains
specific reference to the need to evaluate any inconsistencies between the proposed project and the
applicable air quality management plan. Transportation Control Measures (TCMs) are part of the RAQS.
The RAQS and TCM plan set forth the steps needed to accomplish attainment of state and federal
ambient air quality standards. The California Air Resources Board provides criteria for determining
whether a project conforms with the RAQS which include the following:
Is a regional air quality plan being implemented in the project area?
Is the project consistent with the growth assumptions in the regional air quality plan?
15 Rev. 07/03/02
The project area is located in the San Diego Air Basin, and as such, is located in an area where ‘a RAQS is
being implemented. The project is consistent with the growth assumptions of the City’s General Plan and
the RAQS. Therefore, the project is consistent with the regional air quality plan and will in no way
conflict or obstruct implementation of the regional plan.
b) Violate any air quality standard or contribute substantially to an existing or projected
air quality violation?
Less Than Significant Impact. The closest air quality monitoring station to the project site is in the City
of Oceanside. Data available for this monitoring site through April, 2002 indicate that the most recent air
quality violations recorded were for the state one hour standard for ozone (one day in both 2000 and
2001) and one day in 2001 for the federal 8-hour average for ozone and one day for the 24-hour state
standard for suspended particulates in 1996. No violations of any other air quality standards have been
recorded recently.
c) Result in a cumulatively considerable net increase of any criteria pollutant for which the
project region is non-attainment under an applicable federal or state ambient air
quality standard?
Less Than Significant Impact. The Air Basin is currently in a non-attainment zone for ozone and
suspended fine particulates. The proposed project would represent a contribution to a cumulatively
considerable potential net increase in emissions throughout the air basin. As described above, however,
emissions associated with the proposed project would be minimal. Given the limited emissions
potentially associated with the proposed project, air quality would be essentially the same whether or not
the proposed project is implemented. According to the CEQA Guidelines Section 15130 (a)(4), the
proposed project’s contribution to the cumulative impact is considered de minimus. Any impact is
assessed as less than significant.
d) ’ Expose sensitive receptors to substantial pollutant concentrations?
No Impact. As noted above, the proposed project would not result in substantial pollutant emissions or
concentrations. In addition, there are no sensitive receptors (e.g., schools or hospitals) located in the
vicinity of the project. No impact is assessed.
e) Create objectionable odors affecting a substantial number of people?
No Impact. Construction of future residential development could generate fumes from the operation of
construction equipment, which may be considered objectionable by some people. Such exposure would
be short-term or transient. In addition, the number of people exposed to such transient impacts is not
considered substantial.
BIOLOGICAL RESOURCES - Would the project:
a) Have a substantial adverse effect, either directly or through habitat modifications, on
any species identified as a candidate, sensitive, or special status species in local or
regional plans, policies, or regulations, or by California Department of Fish and Game
or U.S. Fish and Wildlife Service?
Potentially Significant Unless Mitigation Incorporated: According to the biology report, the 0.64 acre
site contains 0.36 acres of Coastal Sage Scrub, 0.22 acres of ruderal land, and 0.06 acres of developed
land (existing driveway). California adolphia and summer holly are found in significant numbers
throughout the coastal sage scrub habitat on this site and on the adjacent 0.78 acre undeveloped site to the north. Approximately 50 individuals of each species would be impacted directly within the 50 foot brush
management zone (total for both projects). However, according to the report, these impacts are
I
16 Rev. 07/03/02
considered less than significant due to the regional presence of these species within other conserved
portions of the City’s draft Habitat Management Plan.
The project would not encroach into sensitive vegetation andor habitats except for disturbance to a total
of 0.1 I6 acre of CSS to be removed by grading. The proposed mitigation for the removal/disturbance of
CSS consists of the preservation onsite of 0.244 acres of CSS. The undisturbed coastal sage scrub will be
preserved within a dedicated open space easement. To mitigate potential disturbances to the California
gnatcatcher resulting from grading activities, prior to the commencement of grading activities, direct
surveys to locate active gnatcatcher nests shall be conducted by a qualified biologist. If nests are present,
no grading or removal of habitat may take place within 200 feet of active nesting sites during the
nestinghreeding season (mid-February through mid-July).
b) Have a substantial adverse effect on any riparian, aquatic or wetland habitat or other
sensitive natural community identified in local or regional plans, policies, or regulations
or by California Department of Fish and Game or U.S. Fish and Wildlife Service?
c) Have a substantial adverse effect on federally protected wetlands as defined by Section
404 of the Clean Water Act (including but not limited to marsh, vernal pool, coastal,
etc.) through direct removal, filing, hydrological interruption, or other means?
No Impact (b & c) - The project site contains no riparian or wetland habitat or wetlands as defined by
Section 404 of the Clean Water Act.
d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the
use of native wildlife nursery sites?
Less than Significant Impact - The biology report states that because of the geographic position of the
site in the context of surrounding urban development and the dominance of steep slopes, it is unlikely
that the property receives significant use from larger mammals such as mule deer, coyote, and bobcat.
The CSS habitat in this location most likely does not function as a habitat corridor due to it’s lack of
connectivity at it’s northern and southern temini. This habitat may act as a linkage, owing to its
geographical proximity to Agua Hedionda Lagoon, providing a stepping stone for species dispersal.
e) Conflict with any local policies or ordinances protecting biological resources, such as a
tree preservation policy or ordinance?
No Impact - The project 1s consistent with the preservation and mitigation requirements of the City’s
Draft Habitat Management Plan which is used as a standard of review for biological impacts.
0 Conflict with the provisions of an adopted Habitat Conservation Plan, Natural
Community Conservation Plan, or other approved local, regional, or state habitat
conservation plan?
Less than Significant. The subject site is a previously graded infill site which is surrounded by
residential development and is designated as an “Urbafleveloped” area on the City’s Draft Habitat Management Plan. The proposed development would occur primarily within the previously graded
ruderal lands. The project is consistent with the HMP standards in that it preserves 67.7% of the CSS
habitat existing on the site. The HMP does not require off-site mitigation for projects which conserve at
least 67% of the habitat on-site, therefore, additional off-site mitigation should not be required.
g) Impact tributary areas that are environmentally sensitive?
No Impact - The site does not contain any environmentally sensitive tributary area.
17 Rev. 07/03/02
CULTURAL RESOURCES
No Impact. The subject site is a previously graded infill site which is surrounded by residential
development and there will be no impacts on cultural resources. There are no known historical,
archeological, paleontological, or human remains on the project site.
GEOLOGY AND SOILS - Would the project:
a) Expose people or structures to potential substantial adverse effects, including the risk of
loss, injury or death involving:
i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-
Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area
or based on other substantial evidence of a known fault? Refer to Division of
Mines and Geology Special Publication 42.
ii. Strong seismic ground shaking?
iii. I Seismic-related ground failure, including liquefaction?
Less than Significant Impact (a.i. to a.iii.). There are no Alquist-Priolo Earthquake Fault zones within
the City of Carlsbad and there is no other evidence of active or potentially active faults within the City.
However, there are several active faults throughout Southern California, and these potential earthquakes
could affect Carlsbad. The project site is located in an area of stable soil conditions and the risk of
seismic-related ground failure or liquefaction is very minimal (according to City of Carlsbad
Geotechnical Hazards Analysis and Mapping Study, November 1992). In addition, a project specific
Preliminary Geotechnical Investigation was prepared by Vinje & Middleton Engineering, Inc., dated
February 11, 2002. The report states that faults or sheer zones are not indicated on or near proximity to
the project site.
iv. Landslides?
No Impact. The report prepared by Vinje & Middleton Engineering, Inc., stated that landslides or other
forms of slope instability were not indicated in surface exposures nor were they suggested in project
exploratory test excavations. Inclined structure along which bedding failures could develop is not in
evidence at the property.
b) Result in substantial soil erosion or the loss of topsoil?
Less than significant impact. According to the City of Carlsbad Geotechnical Hazards Analysis and
Mapping Study, November 1992, the project site is in an area of low to moderate erosion potential. The
applicant is required to prepare a grading and erosion control plans prior to any construction and it is
anticipated that the latest technologies will be used to eliminate the potential of soil erosion and
sedimentation from the site, both during and post construction.
c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading,
subsidence, liquefaction, or collapse?
d) Be located on expansive soils, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property?
No Impact. .The report prepared by Vinje & Middleton Engineering, Inc. showed no evidence of
landslides or other forms of slope instability on the subject site. The report also included laboratory test
results of soil samples taken from the site. These results showed the onsite soils are generally non-
18 Rev. 07/03/02
expansive to very low expansive sandy deposits. Underlying bedrock and terrace deposit are
predominantly dense and stable units which will provide good support for planned improvements and
engineered fill sections. However, some of the underlying terrace deposits locally occur in a weathered
soft condition near the surface and will be removed and recompacted as part of the project remedial
grading operations as recommended. No substantial risk to life or property is anticipated due to hazards
typically found in expansive soils.
e) Have soils incapable of adequately supporting the use of septic tanks or alternative
wastewater disposal systems where sewers are not available for the disposal of wastewater?
No Impact. Sewers are available to the subject site and the project will be served by a public wastewater
system.
HAZARDS AND HAZARDOUS MATERIALS
No Impact. Based on the nature of a residential land use, there is no routine transport, use or disposal of
hazardous materials associated with residential uses. Therefore, there is no potential of a significant hazard associated with the project fiom accidents involving the release of hazardous materials into the
environment, or from the emission of hazardous substances within the proximity of a school.
The project site is not located within an airport land use plan or where such a plan has not been adopted.
However, the project site is located approximately 2.3 miles from the McClellan-Palomar Airport (public
general aviation airport). The project site is not located within any flight, crash, or safety hazard zones
associated with the airport. Therefore, the project will not result in a safety hazard for people residing on
the project site.
The project will not impair the implementation or physically interfere with any adopted emergency
response plan or emergency evacuation since the project site is an infill site surrounded by urban
development which is adequately served by emergency services. There are no wildlands adjacent to the
site that could expose people to significant risk &om wildland fires.
HYDROLOGY AND WATER QUALITY - Would the project:
a) Violate any water quality standards or waste discharge requirements?
No Impact. An erosion control plan and storm water management plan will be prepared prior to
construction of the project. These plans will ensure acceptable water quality standards will be maintained
both during the construction phase as well as post-development.
b) Substantially deplete groundwater supplies or interfere substantially with ground water recharge such that there would be a net deficit in aquifer volume or a lowering of the local
ground water table level (i.e., the production rate of pre-existing nearby wells would drop to
a level which would not support existing land uses or planned uses for which permits have
been granted)?
c) Impacts to groundwater quality?
No Impact. This project does not propose to directly draw any groundwater. The project will be served
via existing public water distribution lines adjacent to the site. Groundwater was not encountered in any
of the exploratory borings made during the soils investigation.
d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner, which would result in substantial
erosion or siltation on- or off-site?
19 Rev. 07/03/02
No impact. The project does not propose to alter existing drainage patterns or the course of a stream or
river that would result in erosion or siltation on or off site.
e) Substantially alter the existing drainage pattern of the site or area, including through the
alteration of the course of a stream or river, or substantially increase the flow rate or
amount (volume) of surface runoff in a manner, which would result in flooding on- or off-
site?
Less than significant impact. On-site drainage will generally flow in the same direction as it flowed
before - down the access portion of the panhandle to Adams Street. No flooding is anticipated due to an
increase in runoff as the percent grade proposed is more than adequate for proper flow of water. In
addition, the street and storm drain system on Adams Street and Park Drive is designed to accommodate
the quantity of water anticipated at buildout.
f) Create or contribute runoff water, which would exceed the capacity of existing or planned
stormwater drainage systems or provide substantial additional sources of polluted runoff?
Less than significant impact. The existing storm drain system as identified in the City’s Master
Drainage and Storm Water Quality Management Plan will adequately convey runoff from the subject site.
According to the Master Plan, no additional upgrades to the storm drain system are necessary as the
existing system can accommodate runoff from a drainage basin developed to its fbll potential.
g) Otherwise substantially degrade water quality?
No ,Impact. The proposed project will not substantially degrade water quality of adjacent receiving
waters.
h) Place housing within a 100-year flood hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood delineation map?
i) Place within 100-year flood hazard area structures, which would impede or redirect flood flows?
No Impact (h & i) - The project site is not located within a 100-year flood hazard area according to the
Flood Insurance Rate Map. Therefore, the proposed project will not result in housing or structures within
a 100-year flood hazard area.
j) Expose people or structures to a significant risk of loss injury or death involving flooding, including flooding as a result of the failure of a levee or dam?
k) Inundation by seiche, tsunami, or mudflow?
No Impact (j & k) - According to the City of Carlsbad Geotechnical Hazards Analysis and Mapping
Study, November 1992, the project site is not located within any dam failure inundation area, or area
subject to inundation by seiche or tsunami.
1) Increased erosion (sediment) into receiving surface waters.
m) Increased pollutant discharges (e.g., heavy metals, pathogens, petroleum derivatives, synthetic organics, nutrients, oxygen-demanding substances and trash) into receiving
surface waters or other alteration of receiving surface water quality (e.g., temperature,
dissolved oxygen or turbidity)?
20 Rev. 07/03/02
n) Changes to receiving water quality (marine, fresh or wetland waters) during or following construction?
0) Increase in any pollutant to an already impaired water body as listed on the Clean Water Act Section 303(d) list?
p) The exceedance of applicable surface or groundwater receiving water quality objectives or degradation of beneficial uses?
No Impact (1, my n, o & p) - The project site is not located immediately adjacent to any body of water.
Drainage from the site is subject to the City’s drainage and storm water pollution control standards
(”DES and best management practices), which ensure that sediment and pollutants discharged fiom
development of the site will be reduced to the maximum extent possible. Also, the City’s drainage and
storm water pollution control standards ensure that development does not reduce water quality of any
marine, fresh or wetland waters or groundwater. Therefore, the project will not adversely impact water
quality.
LAND USE AND PLANNING
No Impact. The subject site is a previously graded infill site which is surrounded by single-family
residential development on the south, east, and west and by a vacant residential parcel land on the north.
Future residential development of the site will be compatible with and will integrate into the existing
community.
The project does not conflict with the property’s General Plan designation (RLM). The density permitted
on the site (3.2 du./ac.) would allow development of the proposed residence and accessory dwelling unit.
The City’s Inclusionary Housing Ordinance requires that 15% if the units be reserved as affordable
housing units for low income households (80% of the AMI) or allows the developers of projects with less
than seven units to pay an Impact Fee. The developer may either designate the Second Dwelling as an
affordable unit by entering into an affordable housing agreement with the City or the Impact Fee may be
paid to satisfy the Inclusionary Housing requirement.
The subject site does not conflict with any habitat conservation plans or natural communities plans in that
the property is designated as “Development” area in the City’s Draft Habitat Management Plan.
The project as proposed and conditioned is consistent with the applicable policies and implementation
standards for land use consistency, preservation of steep slopes and vegetation, drainage, stormwater
runoff and erosion control of the Mello I1 segment of Carlsbad’s Local Coastal Program (LCP). A winter
grading restriction will be added as a project condition of approval. The project is consistent with the
dual criterion provisions allowing a maximum of 10% removal of CSS from steep slopes in that the
project proposes a 7.1% encroachment into dual criteria slopes to allow access and reasonable use of the
property-
MINERAL RESOURCES
No Impact. According to the City of Carlsbad Geotechnical Hazards Analysis and Mapping Study,
November 1992, the project site does not contain any mineral resources. Therefore, the proposed project
will not result in the loss of availability of a known mineral resource or mineral resource recovery site.
NOISE
No Impact (a & b). Based upon the nature of the proposed residential use, the project will not result in
any activity that would generate excessive noise levels, groundbourne vibration, or groundbourne noise
21 Rev. 07/03/02
levels. In addition, the project site is not located adjacent to any use that generates excessive noise or
vibration levels.
Less Than Significant (c & d). Other than traffic generated noise, typical residential land uses do not
generate a substantial amount of noise. With regard to temporary or periodic increase in noise levels, the
only potential increase in noise would be fiom construction activity associated with a future development
project. The City incorporates standard regulations on all project construction activity to ensure that noise
and other potential impacts to surrounding properties are not significant. Therefore, the proposed land
use and zone change will not result in a substantial permanent or temporary increase in ambient noise
levels in the project vicinity above levels existing without the project.
No Impact (e & f) - The project site is located approximately 2.3 miles fiom the McClellan-Palomar
Airport. However, the site is not located within an area impacted by excessive noise levels generated by
the airport. The site is not located near any other public or private airport. Therefore, the proposed
project will not expose people to excessive noise levels generated fiom an airport.
POPULATION AND HOUSING
No Impact. The project would result in the development of one single family residence and a second
dwelling unit on an infill site that is served by existing roads and utilities and therefore, the project would
not induce substantial growth either directly or indirectly. The project is proposed on a vacant lot and
would not displace any existing housing or individuals.
PUBLIC SERVICES
No Impact. The project will result in the construction of one residence and an accessory dwelling unit
which is consistent with the Growth Management Control Point of 2.3 ddac which would allow the
proposed development. The provisions of public facilities within the Zone 1 LFMP including fire &
police protection, parks, libraries and other public facilities, have been planned to accommodate the
projected growth in that area. Because the project will not exceed the total growth projections anticipated
within the Zone 1 LFMP, all public facilities will be adequate to serve the proposed residential
development on the site. Therefore, the project will not result in substantial adverse impacts to or result
in the need for additional government facilities.
RECREATION
No Impacts. As part of the City's Growth Management Program, a performance standard for parks was
adopted. The park performance standard requires that 3 acres of Community Park and Special Use Area
per 1,000 population within a park district (quadrant) must be provided. The project site is located within
Park District #1 in the Northwest 0 Quadrant. The necessary park acreage to achieve the GMP
standard (3 acres/1,000 population) for Park District #1 was based upon the GMP dwelling unit limitation
for the Northwest Quadrant. The project is consistent with the density permitted by the GMP and parks
demand in the NW quadrant currently does not exceed that supply. Therefore, parks facilities are
sufficient to accommodate the project.
TRANSPORTATION/TRAFFIC
Less Than Significant Impact (a). The project will generate 10 Average Daily Trips (ADT) and one
peak hour trip. This traffic will utilize Adam Street. Existing traffic on this street based on an October
2002 count is 1,158 ADT. Since Adams Street is a collector street and collector streets are designed to
accommodate up to 10,000 ADT, the existing street can accommodate the insignificant amount of traffic
generated by the project The proposed project would not, therefore, cause an increase in traffic that is
22 Rev. 07/03/02
substantial in relation to the existing traffic load and capacity of the street system. The impacts from the
proposed project are, therefore, less than significant.
Less Than Significant Impact @). SANDAG acting as the County Congestion Management Agency
has designated three roads (Rancho Santa Fe Rd., El Camino Real and Palomar Airport Rd.) and two
highway segments in Carlsbad as part of the regional circulation system. The Existing and Buildout
average daily traffic (ADT) and Existing LOS on these designated roads and highways in Carlsbad is:
Existing ADT* - LOS Buildout ADT*
Rancho Santa Fe Road 15-32 “A-C’’ 28-43
El Camino Real 21-50 “A-C” 32-65
Palomar Airport Road 10-52 “A-B” 29-77
SR 78 120 “F” 144
1-5 183-198 “D 2 19-249
*The numbers are in thousands of daily trips.
The Congestion Management Program’s (CMP) acceptable Level of Service (LOS) standard is “E”, or
LOS “F” if that was the LOS in the 1990 base year (e.g., SR 78 in Carlsbad was LOS “F” in 1990).
Accordingly, all designated roads and highways are currently operating at or better than the acceptable
standard LOS.
Note that the buildout ADT projections are based on the full implementation of the region’s general and
community plans. The proposed project is consistent with the general plan and, therefore, its traffic was
used in modeling the buildout projections. Achievement of the CMP acceptable Level of Service (LOS)
“E” standard assumes implementation of the adopted CMP strategies. Based on the design capacity(ies)
of the designated roads and highways and implementation of the CMP strategies, they will function at
acceptable level(s) of service in the short-term and at buildout.
No Impact (c, d, e, f). The proposed project does not include any aviation components. The project is
consistent with the Comprehensive Land Use Plan for the McClellan-Palomar Airport and would not,
therefore, result in a change of air traffic patterns or result in substantial safety risks.
All project circulation improvements will be designed and constructed to City standards; and, therefore,
would not result in design hazards. The proposed project is consistent with the City’s General Plan and
zoning and would not increase hazards due to an incompatible use.
The proposed project has been designed to satisfy the emergency requirements of the Fire and Police
Departments. The project complies with the City’s parking requirements to ensure an adequate parking
supply. The project is located in an area which is not planned to be served by public transportation.
UTILITIES AND SERVICES SYSTEMS
No Impact - The proposed residential development will be required to comply with all Regional Water
Quality Control Board Requirements. In addition, the Zone 1 LFMP anticipated that the project site
would be developed with a residential use and wastewater treatment facilities were planned and designed
to accommodate future residential uses on the site. All public facilities, including water facilities,
wastewater treatment facilities and drainage facilities, have been planned and designed to accommodate
the growth projections for the City at build-out. The proposed development on the site will increase the
demand for these facilities. However, the proposed density would not result in an overall increase in the
City’s growth projection in the NW quadrant. Therefore, the project will not result in development that
will result in a significant need to expand or construct new water facilities/supplies, wastewater treatment
or storm water drainage facilities.
23 Rev. 07/03/02
The project has been reviewed by the local solid waste disposal provider (Coast Waste). Existing waste
disposal services are adequate to serve the proposed residential use on the site without exceeding landfill
capacities. In addition, the proposed residential development will be required to comply with all federal,
state, and local statutes and regulations related to solid waste.
MANDATORY FINDINGS OF SIGNIFICANCE
a) Does the project have the potential to degrade the quality of the environment,
substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife
population to drop below self-sustaining levels, threaten to eliminate a plant or animal
community, reduce the number or restrict the range of a rare or endangered plant or
animal or eliminate important examples of the major periods of California history or
prehistory?
Significant Unless Mitigation Incorporated -The proposed residential project will not degrade the
quality of the environment. The project site does not contain any fish or wildlife species. Therefore, the
project will not reduce the habitat of a fish or wildlife species. The project site is a vacant site which was
previously graded and is surrounded by single-family development. The site will conserve 67% of the
coastal sage scrub, consistent with the City’s draft Habitat Management Plan, and this area will be
preserved under a dedicated open space easement. In order to mitigate potential disturbances to the
California gnatcatchers resulting from grading activities, direct surveys will be performed prior to grading
operations. If nests are present, grading will not be permitted during the nestinghreeding season.
Therefore, the project will not threaten or reduce the number a plant or animal community.
There are no historic structures on the site and there are no known cultural resources on the site. The
project will not result in the elimination of any important examples of California History or prehistory.
b) Does the project have impacts that are individually limited, but cumulatively
considerable? (‘(Cumulatively considerable” means that the incremental effects of a
project are considerable when viewed in connection with the effects of past projects, the
effects of other current projects, and the effects of probable future projects?)
. Less than Significant Impact - San Diego Association of Governments (SANDAG) projects regional
growth for the greater San Diego area, and local general plan land use policies are incorporated into
SANDAG projections. Based upon those projections, region-wide standards, including storm water
quality control, air quality standards, habitat conservation, congestion management standards, etc, are
established to reduce the cumulative impacts of development in the region. All of the City’s development
standards and regulations are consistent with the region-wide standards. The City’s standards and
regulations, including grading standards, water quality and drainage standards, traffic standards, habitat
and cultural resource protection regulations, and public facility standards, ensure that development within
the City will not result in a significant cumulatively considerable impact.
There are two regional issues that development within the City of Carlsbad has the potential to have a
cumulatively considerable impact on. Those issues are air quality and regional circulation. As discussed
above, the project would contribute to a cumulatively considerable potential net increase in emissions
throughout the air basin. As described above, however, emissions associated with the residential
development would be minimal. Given the limited emissions potentially associated with the residential
development of the site, air quality would be essentially the same whether or not the residential
development is implemented. According to the CEQA Guidelines Section 15 130 (a)(4), the project’s
contribution to the cumulative impact is considered de minimus. Any impact is assessed as less than
significant.
Also, as discussed above, the County Congestion Management Agency (CMA) has designated three roads
(Rancho Santa Fe Rd., El Camino Real and Palomar Airport Rd.) and two highway segments in Carlsbad
as part of the regional circulation system. The CMA has determined, based on the City’s growth
24 Rev. 07/03/02
projections in the General Plan, that these designated roadways will function at acceptable levels of
service in the short-term and at build-out. The pfoject is consistent with the City’s growth projections,
and therefore, the cumulative impact from the project to the regional circulation system is less than
significant.
With regard to any other potential impact associated with the project, City standards and regulations will
ensure that residential development of the site will not result in a significant cumulatively considerable
impact.
c) Does the project have environmental effects, which will cause the substantial adverse effects on human beings, either directly or indirectly?
Less than Significant Impact - Based upon residential nature of the project and the fact that future
development of the site will comply with City standards, the project will not result in any direct or
indirect substantial adverse environmental effects on human beings.

REVISED Mitigation Measures
4. To mitigate potential disturbances to the California gnatcatcher
resulting from grading activities, prior to the commencement of
grading activities, direct surveys to locate active gnatcatcher
nests shall be conducted by a qualified biologist. If nests are
present, no grading or removal of habitat may take place within
200 feet of active nesting sites during the nesting/breeding
season (February 15 to August 31).
5. Prior to construction activities, a qualified biologist shall survey
the habitat areas adjacent to the project site to determine if any
gnatcatcher nests are within a distance potentially affected by
noise from these activities. If no nesting gnatcatchers are
located no additional measures will need to be taken to mitigate
indirect impacts. However, if nesting gnatcatchers are observed,
no actability will occur without noise attenuation (e.g. noise
barriers) to ensure that noise levels within occupied gnatcatcher
habitat do not exceed 60 dBA.
6. All outdoor lighting shall be shielded and directed away from the open space in order to reduce the potential for indirect lighting
effects fro the proposed project.
