MITIGATED NEGATIVE DECLARATION
CASE NAME:
CASE NO: CDP 03-41
PROJECT LOCATION:
Dunn Property Storm Drain Replacement
Northern terminus of Highland Drive/APN 156-05 1-24
PROJECT DESCRIPTION: The project consists of replacement of a deteriorated and failed storm drain
pipeline on private property. The original pipeline was part of storm drain improvements constructed in
approximately 1965. The system was designed to collect storm drain runoff from the northern end of
Highland Drive and direct it via a 24 inch underground pipeline down a steep slope to undeveloped portions
of the Hosp Grove property. The upper portion of the slope has been affected by undocumented fill and
subsequent erosion. Over time erosion has exposed portions of the galvanized steel pipeline. The exposed
portions rusted, and pieces have broken off, resulting in accelerated erosion of the lower part of the slope.
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
(EIA Part 2) identified potentially significant effects on the environment, and the City of Carlsbad finds as
follows:
IXI
0
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.
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).
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 further is
required.
A copy of the initial study (EIA Part 2) documenting reasons to support the Negative Declaration is on file
in the Planning Department, 1635 Faraday Avenue, Carlsbad, California 92008.

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 (EIA 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 Commission.
A copy of the initial study (EM 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
approval/adoption by the City of Carlsbad Planning Commission. Additional public notices will
be issued when those public hearings are scheduled. If you have any questions, please call Anne
Hysong in the Planning Department at (760) 602-4622.

PROJECT DESCRIPTION/ ENVIRONMENTAL SETTING AND SURROUNDING LAND
USES:
PROJECT DESCRIPTION: The project consists of replacement of a deteriorated and failed
storm drain pipeline on private property. The original pipeline was part of storm drain
improvements constructed in approximately 1965. The system was designed to collect storm
drain runoff from the northern end of Highland Drive and direct it via a 24 inch underground
pipeline down a steep slope to undeveloped portions of the Hosp Grove property. The upper
portion of the slope has been affected by undocumented fill and subsequent erosion. Over time
erosion has exposed portions of the galvanized steel pipeline. The exposed portions rusted, and
pieces have broken off, resulting in accelerated erosion of the lower part of the slope. In the past
three years erosion has been severe. Although the situation has not reached the level of an
emergency, replacement of the pipeline is an urgent matter to prevent further damage to the
slope. Construction will involve removal of the exposed and broken pipeline, removal or
abandonment-in-place of the remaining buried pipeline, trenching down the slope , installation of
a new 36 inch pipeline with appropriate soil cover, and repair of the most severely damaged
lower slope area. The storm drain replacement will be realigned and all work will be done within
a 20’ wide drainage easement to be dedicated to the City by the property owner. The existing
drainage easement held by the City will be abandoned. The work will be coordinated with
remedial grading of the developable residential pad at the top of the slope. A new energy
dissipater will be installed at the outlet of the pipeline on the property line. The existing inlet
structure on Highland Drive will be modified.
1 Rev. 07/03/02
ENVIRONMENTAL SETTING: The project location is a north-facing bluff composed of
relatively fragile sandstone overlain by undocumented, unconsolidated fill. Geologically, the site
is underlain by Formational rock units that range from Pleistocene age terrace deposits at the
near surface to Eocene age sandstone units at depth. Site topography ranges from nearly level in
the upper southwesterly reaches of the site to steeply sloping, and locally vertical, canyon terrain
within the northwestern margin of the property, with more than 50 ft. of vertical relief. The lower
slope failure has not yet affected the upper graded slope. However, future local impacts within
the storm drain alignment are considered likely, particularly in an event of heavy rainfall. The
upper, more level part of the site is less stable due to the unconsolidated fill. A single family
home is proposed for this part of the site (Coastal Development Permit CDP 02-42). Remedial
grading is proposed to stabilize the building pad area. Some retaining walls will be constructed to
further stabilize the slope. The face of the slope supports sparse vegetation consisting of a mix
of native and non-native plant species. There are no permanent streams on the site, but an open
channel has formed due to the combination of natural and accelerated runoff fiom above. The
open channel carries water during storm events but contains no wetland or riparian vegetation.
No cultural features or remains are known or expected to occur on the site.
SURROUNDING LAND USES: The project site is located on the edge of an older residential
area that borders the undeveloped Hosp Grove. To the west, south and east of the project site,
uses are entirely residential, with General Plan designation of Residential Low Medium (RLM)
and Zoning of R-1. Lots range in size fiom approximately 8,000 sq. ft. to over 2 acres. To the
north of the site is the City-owned Hosp Grove which has a General Plan Designation and Zoning
of Open Space. All existing residential uses are located on a flat mesa and are geologically
stable.

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 IMPACT 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.

4 Rev. 07/03/02
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.
0 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.
0 “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.
0 “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.
0 “Potentially Significant Impact” is appropriate if there is substantial evidence that an
effect is significantly adverse.
0 Based on an “EM-Part 11”, 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.
0 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.
5 Rev. 07/03/02
8 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.
e 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 1.mpact Unless
Mitigation Incorporated” may be checked and a Mitigated Negative Declaration may be
prepared.
8 An EIR must 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
VII. AESTHETICS
Less Than Significant Impact. The project will have a slight but insignificant affect on
aesthetics by modifying the appearance of a bluff face. This impact is less than significant
because it is not an entirely natural geologic feature, having been created in part by the
accelerated erosion due to failure of the storm drain. In addition, the slope is not visible fiom any
public road or public viewpoint. Although Jefferson Street is identified as a Natural Open Space
Corridor by the City's Scenic Corridor Guidelines, the site is not visible from Jefferson Street
and the project would not obstruct lagoon views along the roadway. It is do.wnslope from
existing homes and unlikely to be visible from any existing homes. Therefore, any effect on
aesthetics as a result of the project would be less than significant.
11. AGRICULTURAL RESOURCES
No Impact. There is no agriculture on the site or in the vicinity.
111. 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 fiom 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 9" through loth 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:
17 Rev. 07/03/02
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?
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. The
project would involve minimal short-term emissions associated with grading and
construction. Such emissions would be minimized through standard construction measures
such as the use of properly tuned equipment and watering the site for dust control. Long-
term emissions associated with travel to and from the project will be minimal. Although air
pollutant emissions would be associated with the project; they would neither result in the
violation of any air quality standard (comprising only an incremental contribution to overall
air basin quality readings), nor contribute substantially to an existing or projected air quality
violation. Any impact is assessed as less than significant.
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 15 130 (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. The construction of the proposed project 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.
18 Rev. 07/03/02
IV. 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. A biological resources letter report
was prepared for the project by Cathleen Weigand of Dudek and Associates (see Reference 2).
The project site is highly disturbed by a variety of past events. The report finds no presence of
sensitive plant or animal species on the site and low potential for any sensitive species to occur
due to the state of disturbance of the site. However, some disturbed and sparse Coastal Sage Scrub
remains on the site, and this is a sensitive plant community that is subject to regulation by the U.S.
Fish and Wildlife Service and California Department of Fish and Game. Focused, protocol
surveys for California gnatcatcher were conducted in September 2003, and no gnatcatchers were
found.
Direct impacts to approximately 0.21 acre of sparse coastal sage scrub and disturbed coastal sage
scrub/southern mixed chaparral vegetation will occur within the proposed 30’ wide impact area.
However, this vegetation is not connected with or part of a larger block of habitat. Using the flow
chart for evaluating coastal sage scrub impacts provided in the Natural Community Conservation
Planning Guidelines (see Reference 3), this site rates low potential value for long-term
conservation.
The impact to .21 acre sparse coastal sage scrub and disturbed coastal sage scrub/southem mixed
chaparral vegetation shall be mitigated at a ratio of 2:l by creation of 0.21 acres of native habitat
onsite, offsite on the adjacent Hosp Grove property, or offsite at a location acceptable to the City
and wildlife agencies, and preservation of .21 acre offsite in a coastal habitat mitigation bank
such as Whelan Ranch in Oceanside, such that the result is no net loss of habitat in the Coastal
Zone. The project will require a Section 4(d) de minimus habitat loss permit exemption should
the HMP not be approved prior to issuance of a grading permit.
Substantial restoration may be substituted for creation if the area proposed for restoration is
severely disturbed, severely infested with invasive non-native species, or otherwise devoid of
habitat value. Restoration shall reestablish habitat type(s) that were historically present but have
suffered habitat conversion or such extreme degradation that most of the current dominant
species are not part of the original vegetation. All habitat creation or restoration work shall be
carried out by a licensed landscape contractor under the direct supervision of a biologist,
botanist, ecologist, or landscape architect with documented experience in native plant restoration.
A revegetation plan shall be prepared to the satisfaction of the City and any regulatory agencies
having jurisdiction over the project. The revegetation plan shall include specific success criteria.
The area of habitat creation or restoration shall be monitored for a period of 1 year to ensure that ,
success criteria are met. If success criteria are not met within 1 year, the monitoring period shall
be extended until success criteria are met. Thereafter, the City of Carlsbad Public Works
Department shall maintain the mitigation area in a healthy and thriving condition.
Pursuant to Government Code section 65871 and Carlsbad Municipal Code Title 20, Chapter
20.04, section 20.04.140 the applicant shall record a conservation easement over the mitigation
area in favor of the City of Carlsbad, with the California Coastal Commission named as a third
party beneficiary.
Temporary indirect impacts to adjacent vegetations communities such as coastal sage scrub
would potentially result from edge effects. The potential indirect impacts resulting from
construction activities include dust, noise, and general human presence that may temporarily
19 Rev. 07/03/02
disrupt species and habitat vitality and lead to construction related soil erosion and run-off.
However, temporary indirect impacts will be avoided in that all project grading will be subject to
the typical restrictions (BMPs) and requirements that address erosion and runoff (NPDES,
SWPPP). BMPs would include but are not limited to placement of silt fencing, haybales and/or
sandbags in potential drainage areas, watering of grading area, and snow fencing of the limits of
grading. Due to the grading restrictions and requirements mentioned above, the project would
not result in significant short term indirect impacts to sensitive biological resources.
. The project will also impact .01 acre of eucalyptus woodland and .1 acre of
developedomamental. Eucalyptus woodland is not native to California and is not considered a
sensitive habitat type; however, non-developed lands, including eucalyptus woodland, are
covered under the HMP. In accordance with the HMP, the City has adopted an In-lieu Mitigation
Fee consistent with Section E.6 of the Habitat Management Plan and City Council Resolution
No. 2000-223 to fund mitigation for impacts to certain categories of vegetation and animal
species. The City has determined that all projects will be required to pay the fee in order to be
found consistent with the Habitat Management Plan and the Open Space and Conservation
Element of the General Plan. The fee becomes effective following final approval of the Habitat
Management Plan.
Eucalyptus trees may be used for roosting or nesting by raptors and other birds, but no nests were
observed during the gnatcatcher surveys. The breeding season for nesting birds occurs
approximately February 15 through August 3 1; however raptors may begin breeding as early as
January. Several bird species may nest in the habitat onsite. Indirect impacts to breeding birds
may occur if activities occur during the breeding season. The indirect impact would be
associated with grading activities and temporary. Indirect impacts can be avoided by
constructing outside the breeding season or assuring that construction activity will not result in
noise levels above 60 dBA leq at the nest site. If construction is planned during the bird breeding
season, vegetation should be cleared prior to the breeding season. Additionally, if construction
occurs during raptor breeding season (approximately February 1 to August 30) a qualified
biologist should conduct a pre-construction survey of the project site and surrounding habitat to
determine whether there are active raptor nests within the area. If an active raptor nest is
observed, a buffer should be established between the construction activities and the nest so that
nesting activities are not interrupted. The buffer should be a .minimum of 500 feet and should be
in effect as long as construction is occurring and until the nest is no longer active.
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?
Less Than Significant Impact. The Dudek report indicates no riparian, aquatic, or wetland
habitat on the site. An open channel exists but it is unvegetated.
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, filling, hydrological interruption, or other means?
Potentially Significant Unless Mitigation Incorporated Impact. As indicated in the response
above, the biological report by Dudek indicated no wetland, marsh, vernal pool, or other wetland
habitat exists onsite. 0.06 acre of open channel that carries water during storm events is located to
the west of the storm drain impact area. The project will not impact the open channel; however,
due to project’s proximity to the open channel, indirect impacts shall be avoided through the
installation by hand of rip-rap (outside of the channel only), silt fencing shall be installed, and a
biological monitor shall be present during construction in this area to ensure no impacts occur to
downstream waters.
20 Rev. 07/03/02
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?
No Impact. As noted above, the site is not part of a wildlife corridor. It is on the edge of existing
urban development which has been developed for approximately 40 or more years. The site is
adjacent to Hosp Grove which is a relatively large, undeveloped grove of eucalyptus woodland.
Nearby but further removed from the site are Buena Vista Creek and Lagoon. However, the
eucalyptus woodland has very limited usefulness for wildlife and does not provide a comdor or
linkage for wildlife movement. Therefore, the project will not have a significant impact on the
movement of any wildlife species.
e. Conflict with any local policies or ordinances protecting biological resources, such as a tree
preservation policy or ordinance?
No Impact. The City of Carlsbad has a local plan, the Habitat Management Plan (HMP), which
describes the actions necessary to adequately conserve self-sustaining populations of native
wildlife and plant species (see Reference 4). The HMP includes provisions for allowing impacts
to small, isolated pockets of disturbed habitat such as this site. Because this site has such low
value for conservation, the HMP allows public and private projects to impact the habitat in
exchange for mitigation as specified in the plan. The City has no tree preservation policy that
would apply in this case. Therefore, the project will not conflict with local policies or
ordinances.
f. 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 Impact. The Carlsbad HMP is a part of the Natural Community
Conservation Plan (NCCP) and the North San Diego Multiple Habitat Conservation Plan
(MHCP)(see Reference 5). The project has been analyzed by the Carlsbad Planning Department
for consistency with these adopted plans, and the Department finds that it is fully consistent
with the provisions of NCCP and MHCP. Both the HMP and NCCPMHCP allow for incidental
impacts to small, isolated fragments of habitat in exchange for adequate mitigation (see
response to item b above). The impacts of this project are small (less than 0.21 acre of coastal
sage scrub), isolated from other habitat areas, and possessing low potential value for
conservation. Therefore, the project does not conflict with the provisions of the adopted HMP,
MHCP or NCCP.
The project is also located within the Coastal Zone of Carlsbad and is subject to the jurisdiction
of the California Coastal Commission and the Mello II segment of the Carlsbad Local Coastal
Program (LCP). Recently, the Coastal Commission approved new policies for permitting
impacts to environmentally sensitive habitat in the coastal zone (Carlsbad LCPA 02-10)(see
Reference 6). While the Coastal Act generally prohibits impacts to any area designated by the
Commission as environmentally sensitive, Carlsbad LCP 02-10 includes provisions for ,
incidental take of habitat if the impact is part of a larger scale conservation plan such as the
HMP, MHCP, or NCCP. LCPA 02-10 also provides specific standards for mitigation when
impacts are allowed. The mitigation emphasizes creation of habitat to replace what is lost due to
impacts, resulting in “no net loss” of sensitive habitat in the coastal zone. The proposed project
is consistent with the criteria for allowing impacts stated in LCPA 02-10, and mitigation
measures incorporated in this MND will ensure that the mitigation requirements of LCPA 02-10
are complied with (see List of Mitigating Measures below). The project will be subject to
approval of a Coastal Development Permit to be issued by the City of Carlsbad following a duly
noticed public hearing. With the mitigation measures incorporated in this MND, the question of
conflict with provisions of adopted plans is reduced to less than significant.
21 Rev. 07/03/02
g. Impact tributary areas that are environmentally sensitive?
Less Than Significant Impact. As noted above, the project site includes an open channel that
carries stormwater. The channel is not vegetated and is not environmentally sensitive.
V. CULTURAL RESOURCES
Less Than Significant Impact. The geological report of the project (see Reference 7) gives no
indication of subsurface cultural or historical resources. There are no historic structures on the
site. The proposed development will occur on previously disturbed area of the site where there
are no known cultural resources. The project will alter a natural bluff face which could be
considered a unique geological feature. However, the bluff face is highly disturbed and eroded
and does not rise to the level of significance, as described in the Aesthetics discussion.
Therefore, the impact to the bluff face is considered less than significant.
VI. GEOLOGY/SOILS. Would the project:
a) Expose people or structures to potential substantial adverse effects, including the risk
of loss, injury or death involving:
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.
Seismic-related ground failure, including liquefaction?
i.
ii. Strong seismic ground shaking?
iii.
iv. Landslides?
Potentially Significant unless mitigation incorporated: 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 risk from
ground shaking is not significant when structures are built pursuant to the Uniform Building
Code (earthquake standards). According to the Geotechnical Update Report prepared by Vinje &
Middleton Engineering for the residential project on this site, the existing northern slope where
the drain pipeline is to be installed is considered marginally stable (low safety factor) and subject
to failure upon saturation, surcharging or a significant seismic event. Provided that the
recommendations specified for remedial grading and foundations by the Geotechnical Update
Report are implemented during construction of the residential project, liquefaction and
seismically induced settlements will not be a factor in the development of the project site.
Therefore, mitigation to avoid significant impacts resulting from unstable soils shall consist of
the implementation of the Geotechnical Update Report recommendations for remedial grading
and foundations as stated in the Vinje & Middleton Engineering Report dated October 1,2003.
According to the a Geotechnical Investigation performed for the project by Ron Gutier and Erik
Nelson in 1989, one relatively large landslide and an area of bedrock downslope creep were
observed on the property. In both the 1989 Geotechnical Investigation and the Geotechnical
Update Report dated October 1, 2003, the site is determined to be favorable for the proposed
development provided the recommendations for remedial grading summarized in the preliminary
geotechnical report are followed.
b) Result in substantial soil erosion or the loss of topsoil?
No Impact: The project’s compliance with standards in the City’s Excavation and Grading
Ordinance that prevent erosion through slope planting and installation of temporary erosion
control means will avoid substantial soil erosion impacts.
22 Rev. 07/03/02
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?
No Impact - The geotechnical analysis performed for the site by Vinje & Middleton finds that
although the site is underlain by loose undocumented fills within the pad and northern slope
areas over Formational sandstone units which are exposed in an overly steepened slope condition
within the lower terrain below, the proposed development is feasible; i.e., unstable soil
conditions will not occur provided the recommendations summarized in the preliminary
geotechnical report are followed.
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?
Less than Significant Impact - The site is favorable for the proposed development provided the
remedial grading and foundation recommendations summarized in the preliminary geotechnical
report are followed.
HAZARDS AND HAZARDOUS MATERIALS
No Impact: Construction of the project has no potential to expose the public to hazards or hazardous
materials.
VIII. HYDROLOGY AND WATER QUALITY
No Impact (a - g) - The project will replace an existing public storm drain system and is subject to City
standards regarding water quality, drainage and erosion control, including storm water permit (NPDES)
requirements and best management practices. The residential project related to this pipeline is
conditioned to require a Storm Water Management Plan (SWMP) that will ensure that it is designed and
constructed in compliance with the City's NPDES General Permit for Storm Water Discharges
Associated with Construction Activity issued by the State Water Resources Control Board and the San
Diego NPDES Municipal Storm Water Permit issued to San Diego County and Cities by the California
Regional Water Quality Control Board.
Therefore, the project will not violate any water quality standards, deplete groundwater supplies or
quality, substantially alter existing drainage patterns, cause substantial erosion or flooding, or
significantly impact the capacity of stormwater drainage systems.
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 development 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?
23 Rev. 07/03/02
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. Therefore, the project will not result in exposing people or
structures to significant risk from flooding as a result of a dam failure, or from inundation by seiche,
tsunami, or mudflow.
Increased erosion (sediment) into receiving surface waters.
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)?
Changes to receiving water quality (marine, fresh or wetland waters) during or
following construction?
Increase in any pollutant to an already impaired water body as listed on the Clean
Water Act Section 303(d) list?
The exceedance of applicable surface or groundwater receiving water quality objectives
or degradation of beneficial uses?
No Impact (1, m, n, o & p) - The project site is not located adjacent to any body of water. Drainage
from the site is subject to the City’s drainage and storm water pollution control standards (NPDES and
best management practices), which ensure that sediment and pollutants from any development of the site
will not discharge into any downstream receiving surface waters. 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. The project is designed to drain into an existing storm drain,
and the project will be conditioned to prepare a Storm Water Management Plan (SWMP) to ensure that
City standards are met.
IX. LAND USE AND PLANNING
b) Conflict with any applicable land use plan, policy; or regulation of an agency with jurisdiction
over the project (including but not limited to the general plan, specific plan, local coastal
program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an
environmental effect?
Less Than Significant Impact. See Biological Resources, Item IV.(f) above.
X. MINERAL RESOURCES
No Impact. The project site does not contain any mineral resources; therefore, the project will not result
in the loss of availability of a known mineral resource or mineral resource recovery site.
XI. NOISE
Less Than significant Impact. Construction of the project will result in some temporarily elevated noise
levels. This impact is less than significant.
XII. POPULATION AND HOUSING
No Impact. Replacement of the existing drainage pipeline raises no issues with regard to population or
housing.
24 Rev. 07/03/02
XIII. PUBLIC SERVICES
No Impact. The drainage pipeline when replaced will create no new demand for public services. Only
routine inspection and maintenance will be needed.
XIV. RECREATION
No Impact. There are no existing or proposed recreational facilities on the project site. The adjacent
Hosp Grove property owned by the City of Carlsbad is used for recreational purposes. However,
replacement of the existing drainage pipeline will not have any’ impact on the public’s ability to continue
to use Hosp Grove for recreational purposes.
XV. TRANSPORTATION/TRAFFIC-Would the project:
a) Cause an increase in traffic that is substantial in relation to the existing traffic load’and
capacity of the street system?
Less Than Significant Impact. The project will temporarily generate an estimated 10 Average Daily
Trips (ADT) and an estimated 4 peak hour trips. This traffic will utilize the following roadways:
Jefferson Street and Highland Drive. Existing traffic on these streets is within the acceptable range and
the peak hour level of service at the arterial intersection(s) impacted by the project is within the
acceptable range. The increase in traffic from the proposed project will not be noticeable, and the street
system has been designed and sized to accommodate traffic from the project and cumulative development
in the City of Carlsbad. The proposed project would not, therefore, cause an increase in traffic that is
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.
b) Exceed, either individually or cumulatively, a level of service standard established by
the county congestion management agency for designated roads or highways?
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* 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 ai2 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)
25 Rev. 07l03l02
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.
a) Result in a change in air traffic patterns, including either an increase in traffic levels or
a change in location that results in substantial safety risks?
No Impact. The proposed project does not include any aviation components. The project is consistent
with the Comprehensive Land Use Plan for the McClellan-Palomar Airport. It would not, therefore,
result in a change of air traffic patterns or result in substantial safety risks. No impact assessed.
b) Substantially increase hazards due to a design feature or incompatible uses?
No Impact. 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. Therefore, it would not increase hazards due to an incompatible use. No
impact assessed.
c) Result in inadequate emergency access?
No Impact. The proposed project has been designed to satisfy the emergency requirements of the Fire
and Police Departments. No impact assessed.
d) Result in inadequate parking capacity?
No Impact. Although temporary construction parking will be needed, after construction there is no
parking requirement associated with the project.
e) Conflict with adopted policies, plans or programs supporting alternative transportation
(e.g., bus turnouts, bicycle racks, etc.)?
No Impact. The project will cerate no permanent traffic demands, and therefore does not have the
potential to conflict with adopted policies.
XVI. UTILITIES AND SERVICES SYSTEMS
No Impact. Replacement of the existing drainage pipleline raises no issues with regard to provision of
water, wastewater, or landfill services to the public. Because the project is replacement of an existing
drainage pipeline, it will not result in any increased need for stormwater conveyance or treatment.
XVII. MANDATORY FINDINGS OF SIGNIFICANCE
0 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 - With the required mitigation, the project will not degrade
the quality of the physical environment. The disturbance of .21 acre of sparse and disturbed CSS habitat
will be mitigated at a ratio of 2:l through revegetation of .21 acre of CSS habitat onsite, on the adjacent
hosp grove property, or offsite at a location accceptable to the city, and preservation of .21 acre offsite
in a coastal habitat mitigation bank, in accordance with Carlsbad Local Coastal Program
Amendment LCPA 02- 10.
26 Rev. 07/03/02
A Federal de minimus “take” permit issued by the USFWS is required for this minor impact prior to
grading. A Coastal Development Permit will also be required.
There are no historic structures on the site.
disturbed and highly eroded bluff face where there are no known cultural resources.
The proposed development will occur on previously
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.
With regard to any other potential impact associated with the project, City standards and regulations
regarding construction of public works projects will ensure that the project will not result in a significant
cumulative considerable impact.
c) Does the project have environmental effects, which will cause the substantial adverse
effects on human beings, either directly or indirectly?
Potentially Significant Unless Mitigation Incorporated - Replacement of the existing drainage
pipeline will comply with the City’s standard public works specifications which are designed to avoid
adverse environmental effects to the public. The project site is located in an area where human beings
could be exposed to hazardous conditions due to unstable soils. The unstable soils can be mitigated
through strict adherence to the recommendations of the Plan Review Geotechnical Update Report for
remedial grading and foundations. Additionally, the residential development will be required to comply
with all applicable federal, state, regional and City regulations, which will ensure that development of the
site will not result in an adverse impact on human beings, either directly or indirectly.

Impact to .21 acre of sparse coastal sage scrub and disturbed coastal sage scrub/southern mixed
chaparral vegetation shall be mitigated at a ratio of 2:l by creation of 0.21 acres of native
habitat onsite, offsite on the adjacent Hosp Grove property, or offsite at a location acceptable
to the City, and preservation of .21 acre offsite in a coastal habitat mitigation bank such as
Whelan Ranch in Oceanside, such that the result is no net loss of habitat in the Coastal Zone.
The project will require a Section 4(d) de minimus habitat loss permit exemption should the
HMP not be approved prior to issuance of a grading permit.
Substantial restoration may be substituted for creation if the area proposed for restoration is
severely disturbed, severely infested with invasive non-native species, or otherwise devoid of
habitat value. Restoration shall reestablish habitat type(s) that were historically present but
have suffered habitat conversion or such extreme degradation that most of the current
dominant species are not part of the original vegetation. All habitat creation or restoration
work shall be carried out by a licensed landscape contractor under the direct supervision of a
biologist, botanist, ecologist, or landscape architect with documented experience in native
plant restoration. A revegetation plan shall be prepared to the satisfaction of the City and any
regulatory agencies having jurisdiction over the project. The revegetation plan shall include
specific success criteria. The area of habitat creation or restoration shall be monitored for a
period of 1 year to ensure that success criteria are met. If success criteria are not met within
1 year, the monitoring period shall be extended until success criteria are met. Thereafter, the
City of Carlsbad Public Works Department shall maintain the mitigation area in a healthy
