PROJECT SUMMARY
A coastal development permit and mitigated negative declaration for the Phase 2a habitat
restoration at an 11.3-acre site located at the mouth of Big Canyon (APN#440-092-79).
The City of Newport Beach and the Newport Bay Conservancy propose to restore historic
riparian habitat by removing non-native vegetation and replanting native species, creating
a mosaic of native and sustainable habitats, stabilizing the creek and floodplain with
erosion control measures, and enhancing public access and education within the Big
Canyon Nature Park with improved trails and closure of illegal trails. The project also
includes maintenance of the restored habitat area and erosion control measures to
ensure that the plants are established and erosion control features function as designed.
Appropriate management of the natural resources within Big Canyon Park are important
to meet the City’s goal of enhancing habitat and recreational resources in their open
space. The proposed habitat restoration project is planned in coordination with the
Resource and Recreation Management Plan (RRMP) prepared by the Irvine Ranch
Conservancy under contract with the City of Newport Beach for the Big Canyon Nature
Park. The RRMP provides a framework for restoration and recreational improvements in
the Nature Park that will be consistent with the requirements of the Natural Community

Conservation Plan/Habitat Conservation Plan (NCCP) for the Central and Coastal sub -
region of Orange County in the event the City elects to incorporate the Nature Park into
the NCCP.
As shown in Attachment No. ZA 3, Phase 1 of the habitat restoration project was
completed in mid-2017. Currently, the City has funding to initiate the restoration efforts
that are part of Phase 2a (proposed project). Future restoration phases will be proposed
as a separate project, as future funding is available. Potential future restoration efforts
within Big Canyon would also be coordinated with the RRMP.
RECOMMENDATION
1) Conduct a public hearing;
2) Adopt Draft Zoning Administrator Resolution No. _ adopting Mitigated Negative
Declaration No. MD2018-001 (SCH No. 2018081098) and approving Coastal
Development Permit No. CD2018-027 (Attachment No. ZA 1).
DISCUSSION
General Plan
The subject property is located in the OS (Open Space) land use designation in
the Land Use Element of the General Plan. The OS designation is intended to
provide areas for a range of public and private uses to protect, maintain, and
enhance the community’s natural resources. The existing Big Canyon Park and
proposed habitat restoration are consistent with the public use intended for this
land use designation.
Natural Resources Policy NR16.2, of the General Plan Big Canyon Creek
Restoration Project, states,
“Coordinate the Big Canyon Creek Restoration Project so that its outcomes are
consistent with goals for Upper Newport Bay established by Orange County and
the Department of Fish and Game. (Imp 14.3, 14.7)”
As shown in Attachment No. ZA 3, Phase 1 of the habitat restoration project was
completed in mid-2017. The proposed habitat restoration project is planned in
coordination with the RRMP for the Big Canyon Nature Park. Phase 2a of the habitat
restoration project for Big Canyon is designed in such a way that it is consistent with
the nearby NCCP/HCP and may be petitioned to be designated in the future.

Coastal Land Use Plan/Local Coastal Program
The subject property is located in the OS (Open Space) Coastal Zoning District,
which provides areas for a range of public and private uses to protect, maintain, and
enhance the community’s natural resources and maintain and protect landscaped
open space areas located within residential and nonresidential developments, where
no further development is allowed. Passive parks such as the one found in Big
Canyon Park are permitted and consistent with the OS coastal zoning district.
A coastal development permit is required for the proposed habitat restoration and the
property is not eligible for a waiver for de minimis development because the property
is located in the Coastal Commission appeal area.
The project site is described as “Study Area No. 7: Mouth of Big Canyon” in the
Coastal Land Use Plan, being a portion of the 52.0-acre site on the east side of
Newport Bay, between Back Bay Drive and Jamboree Road and bordered by Upper
Newport Bay to the west and residential development to the east, north, and south
of the site. Potential impacts to the natural habitats in this area include erosion, creek
water quality runoff, sedimentation, erosion, increased human activity, ambient
noise, invasive species, and uncontrolled public access. The proposed restoration of
riparian habitat, restoration, and creation of a mosaic of native and sustainable
habitats, stabilization of the creek and floodplain, and inclusion of preventative
erosion features will provide a higher quality habitat and improve the hydrology and
quality of the creek.
Big Canyon is identified as an Environmental Study Area (ESA) in Figure NR2 of the
Natural Resources Element in the General Plan and in Policy 4.1.3 (Environmental
Study Areas) of the Coastal Land Use Plan. Coastal Land Use Plan Policy 4.1.3-1
(B-G, N), states the following applicable policy relative to ESA at the Mouth of Big
Canyon.
“Utilize the following mitigation measures to reduce the potential for adverse
impacts to ESA natural habitats from sources including, but not limited to, those
identified in Table 4.1.1:
B. Where pedestrian access is permitted, avoid adverse impacts to sensitive areas
from pedestrian traffic through the use of well-defined footpaths, boardwalks,
protective fencing, signage, and similar methods.
C. Prohibit the planting of non-native plant species and require the removal of non-
natives in conjunction with landscaping or revegetation projects in natural habitat
areas.
D. Strictly control encroachments into natural habitats to prevent impacts that
would significantly degrade the habitat.
E. Limit encroachments into wetlands to development that is consistent with
Section 30233 of the Coastal Act and Policy 4.2.3-1 of the Coastal Land Use Plan.
3

F. Regulate landscaping or revegetation of blufftop areas to control erosion and
invasive plant species and provide a transition area between developed areas and
natural habitats.
G. Require irrigation practices on blufftops that minimize erosion of bluffs …
N. Prohibit invasive species and require removal in new development.”
The project includes public access enhancements such as surface improvements
along the existing trail at the northerly edge of the project site, additional interpretive
signage, and new limited fencing to delineate sensitive habitat areas. The proposed
habitat restoration plan includes the removal of exotic and invasive plants, replanting
with native vegetation to create a mosaic of coastal habitats, restoring, enhancing,
and improving the resiliency of riparian habitat, and creating wet and high alkali
meadow habitat to improve resiliency of restored habitats. The project area is largely
limited to the lower portions of the Big Canyon Park and does not involve
landscaping, revegetation, or irrigation of any of the surrounding bluff areas.
Section 21.30B.030 (Environmentally Sensitive Habitat Areas) of the Local Coastal
Program Implementation Plan regulates any area in which plant or animal life or
their habitats are either rare or especially valuable because of their special nature
or role in an ecosystem and which could be easily distubed or degraded by human
activities and developments. Several habitat types identified as ESHA occur in Big
Canyon. Within the Phase 2A area (project site), there are four ESHA habitat’s
including southern willow scrub, southern arroyo willow forest, freshwater marsh ,
and a version of alkali meadows. The project will result in the restoration of the
areas that contain the mixed arroyo willow/pepper tree grove vegetation
community. Development and siting within 100 feet of an ESHA is required to
minimize impacts to wildlife and habitat and incorporate low-impact land uses such
as open space and passive recreation whenever feasible. The proposed project
would restore existing open space and passive recreation areas with native
plantings and habitat to accommodate wildlife. The project does not include any
urbanized development such as new buildings or outdoor lighting. Uncontrolled
access to the project site will be improved through the clearing of the invasive
Pepper Tree groves, signage, and fencing. This will help open the area for better
sight lines and enforcement of park hours.
The project will minimize impacts to ESHA areas on-site and ultimately improve
upon the native habitat found on the project site. No adverse effects would occur
to the existing freshwater marsh and alkali meadow ESHA areas. Selective
removal of exotic pepper trees would occur within 2.41 acres of the 2.90 acres of
mixed arroyo willow/pepper tree grove. This work would involve tree removal and
may also include substantial pruning or removal of native willow trees if they are
badly infested with Polyphagous Shot Hole Borer. Wher e feasible, existing
southern willow scrub and southern arroyo forest will be maintained on -site that
have not been impacted by the Polyphagous Shot Hole Borer.

The proposed habitat restoration and minor accessory structures conform to all
applicable development standards. Setbacks for the OS coastal zoning district are
established through coastal development permit process. The proposed project does
not involve the addition of any new habitable structures. Thus, the established
setbacks for the site and habitat restoration are zero feet.
Cultural Resources
Chapter 21.30.105 (Cultural Resources Protection) of the Local Coastal Program
requires the preparation of an Archaeological Research Plan (ARP) for projects
where evidence of potentially significant paleontological/archaeological resources
are found in an initial study pursuant to the California Environmental Quality Act
(CEQA). An ARP has been prepared and peer reviewed by three archaeologists, the
Native American Heritage Commission (NAHC), and the State Historic Preservation
Officer. The ARP includes an analysis of the extent of potential on-site cultural
resources, potential impacts, a mitigation plan, and recommendations for monitoring
and mitigation during any approved grading for the site. The recommendations of
these reviewers will be incorporated into an errata for the final MND prior to the
Zoning Administrator hearing.
Hazards
The property is located in an area known for the potential of seismic activity and
liquefaction. The project will not introduce physical or habitable structures, therefore,
it would not expose people or structures to new potential substantial adverse impacts
related to seismic activity and liquefaction.
Elevations on the Phase 2a project site range from 23 feet up to 60 feet NAVD88
above mean sea level. These site elevations are well above projected sea level rise
in Newport Bay for the next 75 years. Future habitat restoration project phases are
lower lying and may require the preparation of a Coastal Hazards Report to analyze
potential habitat impacts as a result of sea level rise. These future project phases will
be analyzed through a separate coastal development permit application.
Water Quality
The proposed project is required to develop and implement a Stormwater Pollution
Prevention Plan (SWPPP) since the proposed project involves clearing, grading, and
ground disturbance of more than one acre. Pursuant to Section 21.35.030
(Construction Pollution Prevention Plan) of the Municipal Code, when a SWPPP is
required, a Construction Pollution Prevention Plan (CPPP) is required to implement
temporary Best Management Practices (BMP’s) during construction to minimize
erosion and sedimentation and to minimize pollution of runoff and coastal waters
derived from construction chemicals and materials. A CPPP has been prepared and
5
Big Canyon Coastal Habitat Restoration and Adaptation – Phase 2A
Zoning Administrator, October 11, 2018
Page 6
Tmplt: 04/03/18
will be reviewed by the City’s Engineer Geologist prior to issuance of grading/building
permits for site grading. Construction plans and activities will be required to adhere
to the approved CPPP/SWPPP.
Due to the proximity of the development to coastal waters (including wetlands, rivers,
and streams), a Water Quality and Hydrology Plan (WQHP) is required Pursuant to
Section 21.35.050 (Water Quality and Hydrology Plan) of the Newport Beach
Municipal Code. The WQHP will be reviewed and approved by the City’s Engineer
Geologist prior to the issuance of building permits for site grading. The WQHP
includes a polluted runoff and hydrologic site characterization, a description of site
design BMPs including stream bank restoration/stabilization and re-vegetation with
native plantings, and documentation of the expected effectiveness of the proposed
BMPs. Construction plans will be reviewed for compliance with the approved WQHP
prior to building permit issuance.
Coastal access
The project site is not located between the nearest public road and the sea or
shoreline. The project will not affect the public’s ability to gain access to, use, and/or
view Big Canyon Park, the coast and nearby recreational facilities. Vertical access to
the Back Bay is available via existing public access trails around the site, which will
be improved with new surfacing and interpretive signage under the proposed project.
Refer to Figure 12, Proposed Recreation Enhancements, provided as Attachment
No. ZA 4.
Coastal Land Use Plan, Policy 4.4.1-6 and Figure 4-3 (Coastal Views) identify the
closest public view corridors as Back Bay Drive, located approximately 900 feet
west of the project site and Jamboree Road (in the vicinity of Big Canyon Park),
located along the east edge of the project site. Additionally, there are two public
view points located adjacent to Back Bay Drive within the mouth of Big Canyon
area. Coastal views from these view corridors and view points are directed toward
the water at Upper Newport Bay. During construction, construction equipment
would not obstruct coastal views from motorists traveling along Back Bay Drive
and Jamboree Road. From Jamboree Road, there is a 20 to 35 -foot grade
difference to the project area below. The proposed habitat restoration project will
remove invasive plants, and replant with native species, improve public trails,
recreation areas, and viewing areas adjacent to these view corridors consistent
with General Plan Natural Resources Policy 20.5 and as designated in the Coastal
Land Use Plan. The project will not impact coastal views.
Public Comments
To date, the City has received one written public comment letter from Citizens of
The Bluffs (Attachment No. ZA 5). They have identified a number of suggestions
6
Big Canyon Coastal Habitat Restoration and Adaptation – Phase 2A
Zoning Administrator, October 11, 2018

Tmplt: 04/03/18
for the proposed project to address site security in Big Canyon Park including the
addition of more directional signage, signage stating park hours, maintaining
existing gates on-site, and the maintenance of healthy trees on-site. City staff have
also received several calls requesting restrictive fencing and added Police
Department patrols in the area for security purposes.
ENVIRONMENTAL REVIEW
An Initial Study and Mitigated Negative Declaration have been prepared in compliance
with the California Environmental Quality Act (CEQA), the State CEQA Guidelines, and
City Council Policy K-3.
Based upon the analysis of the Initial Study, the environmental categories within which
the project would have either no impact or less than significant impact were: Aesthetics,
Agricultural/Forestry Resources, Air Quality, Geology/Soils and Seismicity, Greenhouse
Gas Emissions, Hazards and Hazardous Materials, Hydrology/Water Quality, Land Use/
Planning, Mineral Resources, Population/ Housing, Public Services, Recreation,
Transportation/Traffic, Tribal Cultural Resources, and Utilities/Service Systems. Based
upon the analysis of the Initial Study, there were no environmental categories within which
the project would have potentially significant unavoidable impacts. Specific mitigation
measures have been included to reduce the potentially significant adverse effects to a
less than significant level for Biological Resources, Cultural Resources, and Noise. A
MMRP has been prepared for consideration and is included with the Final Initial
Study/MND as Exhibit “C” of the draft resolution (Attachment No. ZA 1).
The draft Mitigated Negative Declaration was circulated for a 30 -day comment period
beginning on September 4, 2018 and ending on October 5, 2018. To date, one comment
letter has been received for consideration and is included under Attachment No. ZA 5.
Although not required pursuant to CEQA, written responses have been prepared for each
of the comment letters and they will be included in the Final Initial Study/MND. The errata
and final version of the MND will be available for consideration at the Zoning Administrator
hearing. No new significant information has been present to warrant recirculation of the
MND, and staff recommends adoption of the MND and MMRP.
On the basis of the entire environmental review record, the proposed project, with
mitigation measures, will have a less than significant impact upon the environment and
there are no known substantial adverse affects on human beings that would be caused.
Additionally, there are no long-term environmental goals that would be compromised by
the project, nor cumulative impacts anticipated in connection with the project. The
mitigation measures identified and incorporated in the Mitigation Monitoring and
Reporting Program are feasible and will reduce the potential environmental impacts to a
less than significant level.
The Mitigated Negative Declaration and Mitigation Monitoring and Reporting Program are
attached as Exhibit “C” to the draft resolution (Attachment No. ZA 1).

based, are on file with the Planning Division, City Hall, 100 Civic Center Drive, Newport
Beach, California.
SECTION 3. REQUIRED FINDINGS.
A coastal development permit is required for the proposed habitat restoration and the property
is not eligible for a waiver for de minimis development because the property is located in the
Coastal Commission Appeal Area. In accordance with Section 21.52.015 (Coastal
Development Permits, Findings and Decision) of the Newport Beach Municipal Code, the
following findings and facts in support of such findings are set forth:
Finding:
A. Conforms to all applicable sections of the certified Local Coastal Program.
Facts in Support of Finding:
1. The subject property is located in the OS (Open Space) Coastal Zoning District, which
provides areas for a range of public and private uses to protect, maintain, and enhance
the community’s natural resources and maintain and protect landscaped open space
areas located within residential and nonresidential developments, where no further
development is allowed. Passive parks such as the one found in Big Canyon Park are
permitted and consistent with the OS coastal zoning district.
2. The project site is described as “Study Area No. 7: Mouth of Big Canyon” in the Coastal
Land Use Plan, being a portion of the 52.0 -acre site on the east side of Newport Bay,
between Back Bay Drive and Jamboree Road and bordered by Upper Newport Bay to
the west and residential development to the east, north, and south of the site. Potential
impacts to the natural habitats in this area include erosion, creek water quality runoff,
sedimentation, erosion, increased human activity, ambient noise, invasive species, and
uncontrolled public access. The proposed restoration of riparian habitat, restoration, and
creation of a mosaic of native and sustainable habitats, stabilization of the creek and
floodplain, and inclusion of preventative erosion features will provide a higher quality
habitat and improve the hydrology and quality of the creek.
3. The proposed habitat restoration and minor accessory structures conform to all
applicable development standards. Setbacks for the OS coastal zoning district are
established through the coastal development permit process. The proposed project does
not involve the addition of any new habitable structures. Thus, the established setbacks
for the site and habitat restoration are zero feet.
4. Chapter 21.30.105 (Cultural Resources Protection) of the Local Coastal Program
requires the preparation of an Archaeological Research Plan (ARP) for projects where
evidence of potentially significant paleontological/archaeological resources are found in
an initial study pursuant to the California Environmental Quality Act (CEQA). An ARP
has been prepared and peer reviewed by three archaeologists, the Native American
Heritage Commission (NAHC), and the State Historic Preservation Officer. The ARP
includes an analysis of the extent of potential on-site cultural resources, potential
12

impacts, a mitigation plan, and recommendations for monitoring and mitigation during
any approved grading for the site. The recommendations of these reviewers has been
incorporated into an errata.
5. The property is located in an area known for the potential of seismic activity and
liquefaction. The project will not introduce physical or habitable structures ; therefore, it
would not expose people or structures to new potential substantial adverse impacts
related to seismic activity and liquefaction.
6. Elevations on the Phase 2a project site range from 23 feet up to 60 feet NAVD88 above
mean sea level. These site elevations are well above projected sea level rise in Newport
Bay for the next 75 years. Future project phases are lower lying and may require the
preparation of a Coastal Hazards Report to analyze potential habitat impacts as a result
of sea level rise. These future project phases will be analyzed through a separate coastal
development permit application.
7. The proposed project is required to develop and implement a Stormwater Pollution
Prevention Plan (SWPPP) since the proposed project involves clearing, grading, and
ground disturbance of more than one acre. Pursuant to Section 21.35.030 (Construction
Pollution Prevention Plan) of the Municipal Code, when a SWPPP is required, a
Construction Pollution Prevention Plan (CPPP) is required to implement temporary Best
Management Practices (BMP’s) during construction to minimize erosion and
sedimentation and to minimize pollution of runoff and coastal waters derived from
construction chemicals and materials. A CPPP has been prepared and will be reviewed
by the City’s Engineer Geologist prior to the issuance of grading/building permits for site
grading. Construction plans and activities will be required to adhere to the approved
CPPP/SWPPP.
8. Due to the proximity of the development to coastal waters (including wetlands, rivers,
and streams), a Water Quality and Hydrology Plan (WQHP) is required Pursuant to
Section 21.35.050 (Water Quality and Hydrology Plan) of the Municipal Code. The
WQHP will be reviewed and approved by the City’s Engineer Geologist prior to the
issuance of building permits. The WQHP includes a polluted runoff and hydrologic site
characterization, a description of site design BMPs including stream bank
restoration/stabilization and re-vegetation with native plantings, and documentation of
the expected effectiveness of the proposed BMPs. Construction plans will be reviewed
for compliance with the approved WQHP prior to building permit issuance for site
grading.
Finding:
B. Conforms with the public access and public recreation policies of Chapter 3 of the
Coastal Act if the project is located between the nearest public road and the sea or
shoreline of any body of water located within the coastal zone.
13
Zoning Administrator Resolution No. ####
Page 5 of 12
05-01-2018
Fact in Support of Finding:
1. The project site is not located between the nearest public road and the sea or shoreline.
The project will not affect the public’s ability to gain access to, use, and/or view Big Canyon
Park, the coast, and nearby recreational facilities. Vertical access to the Back Bay is
available via existing public access trails around the site, which will be improved with new
surfacing and signage under the proposed project.
2. Coastal Land Use Plan, Policy 4.4.1-6 and Figure 4-3 (Coastal Views) identify the
closest public view corridors as Back Bay Drive, located approximately 900 feet west of
the project site and Jamboree Road in the vicinity of Big Canyon Park, located along the
east edge of the project site. Additionally, there are two public view points located
adjacent to Back Bay Drive within the Mouth of Big Canyon. Coastal views from these
view corridors and view points are directed toward the water at Upper Newport Bay.
During construction, construction equipment would not obstruct coastal views from
motorists traveling along Back Bay Drive and Jamboree Road. From Jamboree Road,
there is a 20 to 35-foot grade difference to the project area below. The proposed habitat
restoration project will remove invasive plants, and replant with native species, improve
public trails, recreation areas, and viewing areas adjacent to these view corridors
consistent with General Plan Natural Resources Policy 20.5 and as designated in the
Coastal Land Use Plan. The project will not impact coastal views.
In accordance with Section 21.30B.030 (Environmentally Sensitive Habitat Areas) of the
Newport Beach Municipal Code, the following findings and facts in support of such findings are
set forth:
Finding:
C. The resource as identified will not be significantly degraded or disrupted by the proposed
development and the development will be compatible with the continuance of the
resource.
Fact in Support of Finding:
1. Big Canyon is identified as an Environmental Study Area (ESA) in Figure NR2 of the
Natural Resources Element in the General Plan and in Policy 4.1.3 (Environmental
Study Areas) of the Coastal Land Use Plan. Coastal Land Use Plan Policy 4.1.3 -1 (B-
G, N), states the following applicable policies relative to ESA at the Mouth of Big Canyon.
“Utilize the following mitigation measures to reduce the potential for adverse impacts to
ESA natural habitats from sources including, but not limited to, those identified in Table
4.1.1:
B. Where pedestrian access is permitted, avoid adverse impacts to sensitive areas from
pedestrian traffic through the use of well-defined footpaths, boardwalks, protective
fencing, signage, and similar methods.
C. Prohibit the planting of non-native plant species and require the removal of non-
natives in conjunction with landscaping or revegetation projects in natural habitat areas.
14

D. Strictly control encroachments into natural habitats to prevent impacts that would
significantly degrade the habitat.
E. Limit encroachments into wetlands to development that is consistent with Section
30233 of the Coastal Act and Policy 4.2.3-1 of the Coastal Land Use Plan.
F. Regulate landscaping or revegetation of blufftop areas to control erosion and invasive
plant species and provide a transition area between developed areas and natural
habitats.
G. Require irrigation practices on blufftops that minimize erosion of bluffs …
N. Prohibit invasive species and require removal in new development.”
The project includes public access enhancements such a s surface improvements along
the existing trail at the northerly edge of the project site, additional interpretive signage,
and limited fencing to delineate sensitive habitat areas. The proposed habitat restoration
plan includes the removal of exotic and invasive plants, replanting with native vegetation
to create a mosaic of coastal habitats, restoring, enhancing, and improving the resiliency
of riparian habitat, and creating wet and high alkali meadow habitat to improve resiliency
of restored habitats. The project area is largely limited to the lower portions of the Big
Canyon Park and does not involve landscaping, revegetation, or irrigation of any of the
surrounding bluff areas.
2. Section 21.30B.030 (Environmentally Sensitive Habitat Areas) of the Local Coastal
Program Implementation Plan regulates any area in which plant or animal life or their
habitats are either rare or especially valuable because of their special nature or role in
an ecosystem and which could be easily distubed or degraded by human activities and
developments. Several habitat types identified as ESHA occur in Big Canyon. Within the
Phase 2A area (project site), there are four ESHA habitats including southern willow
scrub, southern arroyo willow forest, freshwater marsh, and a version of alkali meadows.
The project will result in the restoration of the areas that contain the mixed arroyo
willow/pepper tree grove vegetation community. Development and siting within 100 feet
of an ESHA is required to impacts to wildlife and habitat and incorporate low-impact land
uses such as open space and passive recreation whenever fe asible. The proposed
project would restore existing open space and passive recreation areas with native
plantings and habitat to accommodate wildlife. The project does not include any
urbanized development such as new buildings or outdoor lighting. Uncontrolled access
to the project site will be improved through the clearing of the invasive Pepper Tree
groves, signage, and fencing. This will help open the area for better sight lines and
enforcement of park hours.
Finding:
D. There is no feasible less environmentally damaging alternative.
Fact in Support of Finding:
1. The project will minimize impacts to ESHA areas on-site and ultimately improve upon
the native habitat found on the project site. No adverse effects would occur to the
existing freshwater marsh and alkali meadow ESHA areas. Selective removal of exotic
pepper trees would occur within 2.41 acres of the 2.90 acres of mixed arroyo
15

willow/pepper tree grove. This work would involve tree removal and may also include
substantial pruning or removal of native willow trees if they are badly infested with
Polyphagous Shot Hole Borer. Where feasible, existing southern willow scrub and
southern arroyo forest will be maintained on-site that have not been impacted by the
Polyphagous Shot Hole Borer.
Finding:
E. All feasible mitigation measures capable of reducing or eliminating project -related
impacts have been adopted. (Ord. 2016-19 § 9 (Exh. A)(part), 2016)
Fact in Support of Finding:
1. The proposed project will incorporate all mitigation measures as required by the
Mitigation Monitoring and Reporting Program included as Exhibit “C”. In particular,
Mitigation Measures BIO-1, BIO-2, and BIO-3 will minimize impacts within ESHA’s to
special status plans, nesting birds, and special-status bats.

Comment No. A-1
The comment request that the natural habitats of the Big Canyon Nature Preserve Park and the creek are
maintained by cleaning up all debris from old broken dead trees and graffiti.
Response to Comment No. A-1
The proposed Project encompasses 11.32 acres and includes the removal of the non-native habitat that includes
the pepper trees and replacement with a mosaic of habitat types consisting of native vegetation. The native
habitats on the Project site that includes the freshwater marsh, alkali heath marsh and the Menzies’s goldenbush
scrub are not proposed to be removed. Up to 0.5 acres of mixed habitat containing native arroyo willows and non-
native pepper trees may also be removed, as well as individual willow trees and branches that are infested with
the Polyphagous Shot Hole Borer (PSHB).
The implementation of the proposed restoration would result in the removal of existing debris from old broken
trees as well as the removal of graffiti on the 11.32-acre project site.
Cleaning up all debris from old broken dead trees and graffiti outside of the Project site is not part of the proposed
Project.
Comment No. A-2
The comment requests the installation of appropriate fencing adjacent to the existing trails that extend around the
Big Canyon Creek area to keep the public out of sensitive habitats and for safety purposes.
Response to Comment No. A-2
Currently, there is no fencing along the existing trails around the Big Canyon Creek area. Signs along the trails
will be included to direct visitors to remain on the trails and out of the habitat restoration area as depicted on
Figure 14 in the IS/MND. Fencing is not proposed, however, the City will revisit their determination to not fence
Big Canyon Creek area during the final design of the Project.
Comment No. A-3
The comment requests installation of more signs placed throughout the entire Big Canyon Natural Park area with
the same content as the current signage.
Response to Comment No. A-3
As illustrated on Figure 14 of the IS/MND, the Project includes proposed interpretive signs and signs for rest
areas. The current signs in the Big Canon Nature Park that are located outside of the Project site prohibit certain

activities within the park. The Project does not include additional signs that prohibit activities because these signs
are appropriate at entrances to the park.
Comment No. A-4
This comment requests that signage in the area state that the park is closed and entrance prohibited from dusk to
dawn or 9 pm to 6 am.
Response to Comment No. A-4
Based on discussions with City staff, there will be a recommendation to modify the park hours restrictions by
stating “No Use of Park Between Dusk and Dawn” and eliminate the current restriction which is “No Use of Park
Between 11:00 PM and 6:00 AM.
Comment No. A-5
This comment requests that the currently installed metal pole gate on the Back Bay Drive side of the Big Canyon
Nature Park adjacent to the Newport Back Bay Parking lot is retained for the safety of the neighborhood.
Response to Comment No. A-5
The existing metal pole gate is located off of the Project site. Modification to the existing gate is not included in
the proposed Project.
Comment No. A-6
The comment requests that a regular random patrolling by police officers or rangers of the Big Canyon nature
park is provided to eliminate camp fires, illegal activities, littering, and graffiti, particularly within the eve ning
hours.
Response to Comment No. A-6
According to City staff, the Newport Beach Police Department does not regularly patrol the Big Canyon Nature
Park, but will respond to incidents. After the construction activities for Phase 1 were completed, there have been
no incidents within the Phase 1 area because the area contains substantially less dense trees. The removal of the
pepper trees within the Project site and the establishment of a meadow habitat within the majority of the Project
site would substantially reduce opportunities for illegal activities because these activities would not be hidden
from views.

Comment No. A-7
The comment requests that the existing, healthy trees not be removed to prevent erosion from flooding and not
create an unnatural park setting.
Response to Comment No. A-7
The proposed restoration project would remove non-native trees and selective removal of some native trees that
exhibit infestation by PSHB. In one discrete 0.5-acre area some willow trees may be removed to conduct stream
and bank stabilization. The project as proposed will improve the long term productivity and health of the site by
replacing the invasive pepper trees with native trees within and adjacent to a stabilized stream and floodplain. The
proposed restoration plan includes engineering the creek and adjacent area to reduce the potential for erosion
during floods.

Comment No. B-1
This comment expressed an opinion that the proposed Project will most definitely have significant negative
impacts.
Response to Comment No. B-1
As discussed in the IS/MND, there are potential significant impacts related to biological resources, cultural
resources, and noise; however, mitigation measures have been recommended to reduce the potential significant
impacts to less than significant.
Comment No. B-2
This comment identified that removal of the mature pepper trees on the Project site would remove (kill) the most
beautiful habitat in the park.
Response to Comment No. B-2
This comment expressed an opinion and does not address the contents of the IS/MND. The proposed project
includes restoration with native habitats and the removal of non-native vegetation. Although the restoration would
alter existing views from Jamboree Road, Back Bay Drive, as well as the public viewpoint west of the project
site, the quality of the views of the project site would be subjective, but would remain aesthetically pleasing, and
impacts to the scenic quality of the project area would be less than significant.
Comment No. B-3
This comment identified that removal of the mature pepper trees on the Project site would remove the root
systems that prevent erosion when the creek floods.
Response to Comment No. B-3
Construction activities would remove the root system of the existing pepper trees. The proposed restoration plan
includes engineering the creek and adjacent area to reduce the potential for erosion during floods. The project
includes erosion control measures as part of the Construction Pollution Prevention Plan (CPPP) located on pages
2, 6 and 8 of the 60% Design Plans in Appendix A of the IS/MND. In addition, the project includes long-term
stabilization measures as part of the Water Quality Management Plan.
Comment No. B-4
This comment identified that removal of the mature pepper trees on the Project site would remove the tree cover
for birds, including two endangered species.

Response to Comment No. B-4
One State and federally-listed Endangered species, least Bell’s vireo, may occur occasionally in the vicinity of the
Project site but has not been reported in the project area. California gnatcatcher, which is federally-listed as
Threatened is known to occur in coastal sage scrub habitat to the south and west of the project area but does not
occur on the Project site. The pepper trees are non-native and do not provide suitable habitat for either species.
Current use of the project area by other avian species is very low as compared with areas containing more native
vegetation. Although there may be a temporary disturbance to nesting habitat and permanent removal of non-
native stands of trees, there will be an overall benefit to native avian species, as well as other wildlife, through
implementation of the proposed project by restoring native habitat to the area, which can be utilized for nesting
and foraging.
Comment No. B-5
This comment identified that removal of the mature pepper trees on the Project site would result in intense heat in
summer as there will be no shade from the trees.
Response to Comment No. B-5
This comment expressed an opinion and does not address the contents of the IS/MND. The vegetation proposed
as part of the restoration is better suited to provide habitat for native wildlife than the existing non-native trees
and shrubs.
Comment No. B-6
This comment identified that removal of the mature pepper trees on the Project site would result in removal of
native species that are close to and intermingled with the pepper trees.
Response to Comment No. B-6
The existing pepper trees which are non-native do not provide good habitat value for native plant or wildlife
species. The description of the proposed project acknowledged that some removal or damage of native vegetation
from the Polyphagous Shot Hole Borer would occur. All vegetation removal is temporary since the project
proposes to establish native vegetation throughout the project area, in all areas subject to removal. The vegetation
proposed as part of the restoration is better suited to provide habitat for native wildlife than the existing non -
native trees and shrubs.
Comment No. B-7
This comment identified that removal of the mature pepper trees on the Project site would prevent new evergreen
trees from re-growing.

Response to Comment No. B-7
The proposed Project includes a restoration plan that has specific plant species based on the soil conditions of the
Project site. Furthermore, based on historical records, the native plant species that were located in the Big Canyon
Nature Park in the past did not include evergreen trees.
Comment No. B-8
This comment identified that removal of the mature pepper trees on the Project site would deprive the existing
educational program utilizing the forest to foster adventure, shade and learning experiences for underprivileged
children bussed into the area for nature study.
Response to Comment No. B-8
This comment expressed an opinion and does not address the contents of the IS/MND. Access to the educational
programs would only be restricted during the 5-month construction period of the project.
Comment No. B-9
This comment identified that removal of the mature pepper trees on the Project site would take away protection
for the indigenous animals from surrounding urban intrusion.
Response to Comment No. B-9
This comment identified that the Project would eliminate protection of native animals from surrounding urban
intrusion. The non-native pepper trees provide habitat of relatively low value for local wildlife. Therefore, the
removal of the non-native pepper trees and replacement with native trees, shrubs, succulents, and herbaceous
species in the near term would not eliminate protection of native animals from surrounding urban intrusion.
Comment No. B-10
This comment identified that removal of the mature pepper trees on the Project site would interfere with the
natural symbiosis between plants and animals existing for decades at the Project site.
Response to Comment No. B-10
This comment identified the relationship of the existing pepper trees and plants and animals. The commenter
does not acknowledge that the invasion of non-native pepper trees constitutes an unnatural condition for this area.
Native animals and wildlife are not associated with the non-native pepper trees.

Comment No. B-11
This comment identified that removal of the mature pepper trees on the Project site would replace beautiful green
with ugly, useless brown brush and stunted green desert plants.
Response to Comment No. B-11
There are no desert plants proposed to be planted in association with this project. Every plant species selected for
planting or seeding occurs in the Upper Newport Bay area. The goal of the project is to implement native habitat
rather than supporting existing invasive species that have resulted from urban interference such as irrigation
runoff.
Comment No. B-12
This comment identified that removal of the mature pepper trees on the Project site would eliminate the scenic
beauty of the forest from all directions, including the homes and apartments surrounding the park and individuals
walking through the park.
Response to Comment No. B-12
This comment expressed an opinion of the scenic view of the Project site and does not comment on the contents
of the IS/MND. The City’s General Plan and Coastal Land Use Plan policies protect public views points and do
not protect private property views. A discussion of public viewpoints is provided in the Aesthetics section of the
IS/MND.
Comment No. B-13
This comment identified that removal of the mature pepper trees on the Project site would deplete the oxygen
making capacity of the park’s habitat because green trees make more oxygen than desert bushes and green trees
absorb more carbon dioxide.
Response to Comment No. B-13
This comment regarding the cycle of oxygen is correct, but this comment does not address the contents of the
IS/MND. No further response is necessary.
Comment No. B-14
This comment disagreed with the finding that the proposed Project would not result in the loss of forest land or
conversion of forest land to non-forest use.

Response to Comment No. B-14
As discussed on page 44 of the IS/MND, in determining whether impacts to forest resources, including
timberland, are significant environmental effects, lead agencies may refer to information compiled by the
Department of Forestry and Fire Protection regarding the State’s inventory of forest lands, including the Forest
and Range Assessment Project and the Forest Legacy Assessment project. Forest lands refer to productive land
for timber; and therefore, the Project site is not identified as forest land because it is not used for producing
timber.
Comment No. B-15
This comment refers to the current environmental conditions of Phase 1 after the construction activities were
completed. The comment provided an opinion that the evergreen trees (i.e., the non-native pepper trees) should
remain and not replaced with native vegetation.
Response to Comment No. B-15
This comment expresses an opinion and does not provide a specific comment on the contents of the IS/MND.
There are a number of objectives of the Project as listed on Page 18 of the IS/MND. The primary purpose is to
restore the Big Canyon Nature Park by removing the exotic and invasive plants and create a mosaic of
ecologically appropriate natural coastal habitats as well as restoring the creek. The existing pepper trees are non-
native and do not provide habitat for sensitive wildlife species.
Comment No. B-16
This comment states that the removal of the pepper trees is proposed because the trees are infested with the
PSHB.

non-native and do not provide habitat for sensitive wildlife species. Some of the native arroyo willows trees are
currently infested with PSHB and are proposed to be removed to reduce the spread of infestation.
Comment No. B-17
This comment requests that a fence be constructed along the fire road around Big Canyon Creek area to prevent
people from falling over the cliff.

Response to Comment No. B-17
As stated in Response to Comment No. A-2 above, there is currently no fencing along the existing fire roads
which are trails around the Big Canyon Creek area. Signs along the trails will be included to direct visitors to
remain on the trails and out of the habitat restoration area. Fencing is not proposed, however, the City will revisit
their determination to not fence Big Canyon Creek area during the final design of the Project. The removal of the
pepper trees would increase visibility to the project area and would discourage nefarious activities that currently
occur within the pepper tree grove.
Comment No. B-18
This comment requested that the existing parking lot off of Back Bay Drive be chained off at night.
Response to Comment No. B-18
The Back Bay Drive parking lot is not located on the Project site, and the Project does not include modifications
to the operation of the existing parking lot. As stated in Response to Comment A-4, there will be a
recommendation by City staff to modify the park hours restrictions by stating “No Use of Park Between Dusk and
Dawn” and eliminate the current restriction which is “No Use of Park Between 11:00 PM and 6:00 AM.
However, this restriction would only apply to the Big Canyon Nature Park and not the Back Bay.
Comment No. B-19
This comment states that the construction of the Project would denude the land because hydrologic forces would
remove smaller plantings and that there would be no guarantee that the restoration efforts would prevent erosion
from flood waters.
Response to Comment No. B-19
As described in the IS/MND, the proposed Project includes the re-contouring of the creek and flood area as well
as provide stabilization of the creek channel. These efforts will reduce the potential for erosion during flood
events.
Comment No. B-20
This comment states that the proposed construction activities will substantially increase noise levels during the
approximately 5 months of construction activities.

Response to Comment No. B-20
The comment is correct. Construction activities for the Project will increase noise levels at the nearby residences;
however, as stated on page 122 of the IS/MND, construction activities would comply with the current City noise
ordinance which limits construction hours between 7:00 am and 6:30 pm on any weekdays and between 8:00 am
and 6:00 pm on any Saturday. All construction work would be prohibited on any Sunday or federal holiday.
Although construction noise levels would be less than significant, noise reduction devices and techniques are
recommended as mitigation measures to reduce construction noise as discussed on pages 126 and 127 of the
IS/MND.
Comment No. B-21
This comment raises a concern regarding the increase of air emissions and surface water pollution during
construction activities.
Response to Comment No. B-21
Construction air emissions are discussed on pages 58 through 60 of the IS/MND and determined that the Project
would not exceed the construction air quality significance thresholds established by the South Coast Air Quality
Management District.
The Project includes a Construction Pollution Prevention Plan (CPPP) that would reduce water quality effects
during construction activities of the Project. The CPPP includes a diversion of water if there is flow in the
channel. This diversion would allow grading activities to occur within the area of the previous active channel.
Comment No. B-22
This comment raises a safety concern regarding the use of Back Bay Drive by workers, vendors, trucks, and
equipment to access the park because Back Bay Drive as a multi-use trail.
Response to Comment No. B-22
As discussed on page 136 of the IS/MND, construction vehicles such as the haul trucks as well as construction
employees, vendors and equipment, would use Back Bay Drive. As noted in the comment, the current speed limit
on Back Bay Drive is 15 miles per hour. All vehicles associated with construction activities of the Project would
limit their speeds to 15 miles per hour. Construction employees and haul truck drivers would be advised of the
haul route and staging locations prior to commencing the construction activities. Information would be provided
that identifies access to the site includes vehicles travelling north on Back Bay Drive from Jamboree Road and
access from the Project site includes vehicles travelling north on Back Bay Drive to East Bluff Drive. Pages 134
and 135 of the IS/MND identified peak hour traffic associated with the Project would include about 24 one-way
trips by employees during the peak hour while during the non-peak hour which is when haul truck would operate,

a maximum of 26 one-way trips over 6 hours during the non-peak hours each day would occur. This would result
in a maximum average of 4 to 6 one-way trips per hour. Because the speed limit on Back Bay Drive is 15 miles
per hour, less than significant traffic safety impacts would occur.
Comment No. B-23
The comment identified that animals in the Project area would be impacted during construction activities.
Response to Comment No. B-23
Pages 67 through 71, provided an evaluation of the potential impacts on plant and wildlife species during
construction activities. As discussed, potential impacts to special-status plant, nesting birds and special-status bats
were found to be potentially significant. Mitigation measures BIO-1 through BIO-3 are provided to reduce the
potential impacts to less than significant.
Comment No. B-24
This comment identified the potential for Native American artifacts within the Project area and that the
construction activities could impact them.
Response to Comment No. B-24
As discussed on pages 83 through 85 of the IS/MND, there is a potential for construction activities to impact
currently unknown historical and archaeological resources. Mitigation measures CR-1 (Archaeological
Monitoring) and CR-2 (Native American Monitoring) have been included to reduce the potential impacts to
unknown historical and archaeological resources to less than significant.

Citizen of Newport Beach
This is a message from a City of Newport Beach citizen representing others living around Big
Canyon Nature Park. The commenter states that the City should implement a fence around the
Big Canyon Creek because there is graffiti and trash around the area, and this is disrespectful to
nature. The Park/Creek area looks like it is a disaster. A fence would keep the public out and
stop the graffiti, littering, decrease the chance of fires starting in the area, and prohibit the use of
drugs and other substances in the Park/Creek area. The commenter recommends that if theCity
wants to use the area for educational purposes, then they have someone open the gate for the
group/educational entity, then close it after they are done. The commenter expresses extreme
concern over these issues and states that it is unacceptable what is currently happening in the
Park. The commenter clearly states that a new fence would keep people out and decrease
these existing issues.

Ms. Makana Nova City of Newport Beach Planning Division October 4, 2018 Page 2 of 2 Our primary concern regarding the proposed project is appropriate disposal of cleared vegetation and management of the spread of invasive Polyphagous and Kuroshio shot hole borers (collectively, ISHBs). We offer the following comments and recommendations to assist the City in avoiding or minimizing potential project impacts on biological resources. The Biological Technical Report (Appendix C) states that, “the proposed project will use pest
management techniques in consultation with experts from the University of California Riverside”
(page 8); however, the draft MND states that, “project implementation would result in the need for disposal of vegetative debris from construction and maintenance activities” at Prima
Deshecha Landfill in San Juan Capistrano” (pages 140-141). Currently, this facility does not have the US Composting Council's Seal of Testing Assurance (STA) as recommended by Dr. Eskalen’s lab at the University of Riverside(http://eskalenlab.ucr.edu/pshb.html). The Department, therefore, recommends consideration of a disposal facility that meets this criteria. More information can be found at https://compostingcouncil.org/seal-of-testing-assurance/. We appreciate the opportunity to comment on the MND for this project and to assist the City in further minimizing and mitigating project impacts to biological resources. The Department requests an opportunity to review and comment on any response that the City has to our comments and to receive notification of the forthcoming hearing date for the project (CEQA Guidelines; §15073(e)).

Mitigated Negative Declaration (MND) for the Proposed
Big Canyon Coastal Habitat Restoration and Adaption Project
The South Coast Air Quality Management District (SCAQMD) staff appreciates the opportunity to
comment on the above-mentioned document. The following comments are meant as guidance for the lead
agency and should be incorporated into the final CEQA Document.
SCAQMD Staff’s Summary of Project Description
The lead agency proposes the restoration of the Big Canyon Coastal Habitat through removal of non-native
plants, replanting of native plants, enhancing public access, and stabilizing the creek and floodplain with
erosion control measures, on 11.3 acres (proposed project).1 The proposed project is located at 1900 Back
Bay Drive, south of the State Route 55 and State Route 73 (SR-73) interchange.
SCAQMD Staff’s Summary of Air Quality Analysis
In the air quality analysis, the lead agency quantified emissions resulting from construction and operation
of the proposed project and compared those emissions to SCAQMD’s air quality CEQA significance
thresholds. Upon review of the air quality analysis, SCAQMD staff found multiple inconsistencies between
the MND and the CalEEMod output file. For example, the lead agency quantified emission reductions
resulting from mitigation measures input into CalEEMod2 but SCAQMD staff found that no mitigation
measures or project design features were identified in the MND. Detailed comments are provided below.
General Comments
Based on the CalEEMod output file, the lead agency relied on mitigation measures to reduce the proposed
project’s NOx emissions during construction from 169 pounds per day to 63 pounds per day. However, in
the MND, the lead agency only reports the proposed project’s mitigated construction emissions value of 63
pounds per day3 of NOx and does not include the mitigation measures that are identified in the CalEEMod
output file that reduce the proposed project’s construction emissions to this less than significant level.
Therefore, SCAQMD staff recommends the lead agency revise the air quality analysis to include both
unmitigated and mitigated emissions resulting from the proposed project.
Additionally, the lead agency states in the MND that the construction phase of the proposed project will
occur over a five month period, however, based on the CalEEMod output file4 the construction period is
nine months. Therefore, SCAQMD staff recommends the lead agency clarify which construction schedule
is more accurate and incorporate this clarification in the final CEQA document.

Recommended Mitigation Measures
The lead agency included Tier 4 off road-construction equipment in the CalEEMod file but did not include
it in the MND. Therefore, SCAQMD staff recommends the lead agency incorporate AQ-1(a) to ensure tier
4 standards are met, and AQ-2(b) to further reduce emissions resulting from on-road trucks during all
construction phases of the proposed project in the MND. Details regarding these recommended mitigation
measures are provided below.
AQ-1 Construction equipment maintenance records (including the emission control tier and/or the engine
emission standard of each equipment) shall be kept on site during construction and shall be available
for inspection by the lead agency.
a)Off-road diesel-powered construction equipment greater than 50 horsepower shall meet
United States Environmental Protection Agency Tier 4 off-road emissions standards. A
copy of each unit’s certified tier specification shall be available for inspection by the lead
agency at the time of mobilization of each applicable unit of equipment.
b) All on-road diesel haul trucks used during the construction phase shall meet or exceed 2010
engine emission standards specified in California Code of Regulations Title 13, Article 4.5,
Chapter 1, Section 2025 or be powered by natural gas, electricity, or other diesel alternative.
Operators shall maintain records of all trucks associated with project construction to
document that each truck used meets these emission standards.
Permits and Compliance with SCAQMD Rules
In the event that the proposed project requires a permit from the SCAQMD, the SCAQMD should be
identified as a responsible agency for the proposed project. For more information on permits, please visit
SCAQMD webpage at: http://www.aqmd.gov/home/permits. Questions on permits can be directed to
SCAQMD’s Engineering and Permitting staff at (909) 396-3385.
Conclusion
Please provide the SCAQMD with written responses to all comments contained herein prior to the adoption
of the final CEQA Document. The SCAQMD staff is available to work with the lead agency to address
these issues and any other questions that may arise. Please contact Robert Dalbeck, Assistant Air Quality
Specialist - CEQA IGR Section, at (909) 396-2139, if you have any questions regarding these comments.

The following correction was required to clarify that the vegetation that is currently infested with the
Polyphagous Shot Hole Borer (PSHB) is some of the existing willow trees. The second paragraph on page 42 of
the IS/MND is revised as follows:
Furthermore, the proposed project includes the removal of the existing Brazilian pepper trees that are
approximately 20 to 30 feet in height, non-native and evergreen. Although these tree species could provide a
visually pleasing view, these species are infested with PSHB that will eventually destroy the trees. The
proposed removal of these non-native evergreen species as well as other exotics and invasive species would
alter distant views from Back Bay Drive and limited views from Jamboree Road, as well as distant eastern
views from the nearest public viewpoint located approximately 600 feet west of the project site within the
western portion of Big Canyon Park. Although these current views would be altered, the proposed vegetation
would provide views of native habitat that can be visually pleasing. the presence of PSHB will result in the
ultimate destruction of the existing pepper trees and the visually pleasing resource will be naturally affected.
Therefore, tThe proposed restoration of the project site with alkali wet and high meadow communities with

vegetation heights of two to three feet would include more sustainable natural plant species. The final project
plantings would continue to provide natural and visually pleasing vegetation as viewed from Back Bay Drive
and Jamboree Road. Although the proposed restoration would alter views from Jamboree Road, Back Bay
Drive, as well as the public viewpoint west of the project site, views of the project site would remain
aesthetically pleasing and impacts to the scenic quality of the project area would be less than significant.
Page 28, IS/MND and Appendix C, Page 8
The following correction addresses the comment made by the California Department of Fish and Wildlife who
addressed the need for clarification of vegetation disposal and information provided in third paragraph on page 28
of the IS/MND and page 8 in Appendix C, The Biological Resources Technical Report:
The stream corridor outside of the pepper trees groves is dominated by native willows that exhibited evidence
of infestation by the Polyphagous Shot Hole Borer (PSHB) noted during field surveys conducted during
Phase 1. The potential infested wood chips from the onsite willow trees would be treated through solarization
at locations along the existing trail that are illustrated on Page 6 of the 60% Design Plans in Appendix A. The
remaining wood chips as well as the dead and non-native vegetation would be disposed of at the Prima
Deshecha Landfill. Subsequent to completing the habitat restoration, tThe proposed project will use long-
term pest management techniques in consultation with experts from the University of California Riverside.
Such techniques may include heavy pruning of the existing infested mature trees and application of soil
amendments and tree injections to improve resilience of existing woody plants. These areas also contain
invasive plant species that will be removed selectively and replaced with native plants. To further improve
sustainability of the replanted native riparian vegetation, woody species and herbaceous plants that are not
highly susceptible to PSHB infestation will be selected. Soil amendments will be also used to reduce salinity
levels and improve biological activity in soils. Similarly, the planned re-vegetation after exotic removal along
the creek channel will use a mixed palette of native vegetation that includes smaller stem plants that are less
desirable to the PSHB. Without these management measures, the existing willow trees and proposed riparian
habitat would be likely to be impacted by the PSHB infestation which eventually causes die off of large
mature trees that would provide potentially suitable habitat for important wildlife, including, for example, the
State and federally Endangered least Bell’s vireo (Vireo bellii pusillus).
Page 126, IS/MND
At the end of the second paragraph on page 126 of the IS/MND, the following is revised to address the intended
hours of operation for the Big Canyon Park with the implementation of the proposed project.
Thus, the construction activities associated with the proposed project would be required to adhere to the
applicable permitted hours of operation established under the City of Newport Beach’s Noise Ordinance. In
addition, the City intends to change the hours of operation for Big Canyon Park to close from "dusk till
dawn,” which may require a future ordinance.

The following text has been revised to address the landfilling of the chipped material from the project site. The
second paragraph on page 141 of the IS/MND is revised as follows:
Project implementation would result in the need for disposal of vegetative debris from construction
and maintenance activities. Solid waste removed from the project site would include dead or nonnative
vegetation. Debris would be removed with construction equipment and transported to the
landfill by haul trucks at the designated haul routes discussed above in Section 3.4.16, Impacts a)
and d). The total estimated vegetation removal is approximately 7,500 cubic yards and the total
estimated soil removal is approximately 1,500 cubic yards. It is anticipated that the project’s
generation of solid waste would be at its greatest during initial construction activities due to the
primary removal of non-native habitat vegetation. Thereafter, the project would result in minimal
removal of dead vegetation during operational maintenance activities. Chipped material totaling up to
approximately 800 cubic yards may be used for top dressing within the replanted area as well as on the trail
located along the northern boundary of the project site. A portion of the 800 cubic yards of chip material is
anticipated to be infested by the PSHB. Only the potential infested wood chips which are anticipated to come
from some of the onsite willow trees would be treated through solarization at locations along the existing trail
that are illustrated on Page 6 of the 60% Design Plans in Appendix A. The remaining wood chips that are no
infected as well as the dead and non-native vegetation that are also not infected would be disposed of at the
Prima Deshecha Landfill. Given the project’s scale, it is anticipated that the specified landfill would have the
adequate capacity to accommodate the project’s waste disposal needs. Therefore, the project would result in a
less than significant impact to landfill capacity.

The following is a correction to the cumulative discussion on page 143 of the IS/MND.
Less than Significant with Mitigation. The proposed project along with other related projects such as Phases
1, 2B and 2C would result in several potentially significant project-level cumulative impacts. Impacts
associated with the related projects would be similar to the impacts associated with the proposed project. As a
result, the cumulative impacts regarding Biological Resources, Cultural Resources and Noise would be
significant. Because the proposed project would result in significant impacts associated with these same issues,
the would project-level impacts regarding Biological Resources, Cultural Resources and Noise. The project’s
contribution to cumulative impacts to Biological Resources, Cultural Resources and Noise would be
cumulatively considerable, and therefore, could result in significant cumulative impacts.

Biological Resources (BIO)
BIO-1: Special-Status Plants Special-Status Plants. Impacts to special-status plants
would be avoided by implementing the following:
a. Within two weeks prior to construction activities, preconstruction surveys shall be
conducted by a qualified Project Biologist to confirm presence/absence of special-
status plant species within the project site. The locations of any special-status plant
species identified during the pre-construction botanical survey, including those with
a CRPR of 1, 2, or 3 shall be flagged (or otherwise delineated and marked) by a
biologist and shall be avoided. To verify avoidance during construction, a qualified
biologist shall be onsite during any ground disturbing activities within 10 feet of a
special-status plant species population.
b. If special-status plant species are observed during the preconstruction surveys within
the portion of the project site proposed for restoration and if avoidance of the special-
status plant species is not feasible, coordination with USFWS and/or CDFW will be
required to confirm suitable mitigation prior to ground-disturbing activities. The
mitigation strategy may include on-site or off-site restoration, translocation, and/or
seed collection, and shall be outlined in a restoration/revegetation plan to be
approved by USFWS and/or CDFW. At a minimum, the plan shall include a
description of the existing conditions, site selection criteria, site preparation and
planting methods, maintenance and monitoring schedule, performance standards,
adaptive management strategies, and identification of responsible parties.

and City of Newport Beach
BIO-2: Nesting Birds. Impacts to nesting birds would be avoided by conducting all
grading and construction activities outside of the bird breeding season (February 15 to
August 31; January 15 to August 31 for raptors). If breeding season cannot be avoided,
the following measures would be followed.
a. During the avian breeding season, a qualified Project Biologist shall conduct a
preconstruction avian nesting survey no more than 3 days prior to vegetation
disturbance or site clearing. If grading or other construction activity begins in the
non-breeding season and proceeds continuously into the breeding season, no
surveys shall be required. However, if there is a break of 3 days or more in grading
or construction activities during the breeding season, a new nesting bird survey shall
be conducted before these activities begin again.
b. The nest survey shall cover all reasonably potential nesting locations on and
within 300 feet of the proposed areas where construction activities will occur.
c. If an active nest is found during an avian nest survey, a qualified Project Biologist
shall implement a 300-foot minimum avoidance buffer for special-status species

(e.g., coastal California gnatcatcher, least Bell’s vireo); a 500-foot minimum
avoidance buffer for all raptor species; and 300-foot minimum avoidance buffer
(or other buffer as determined appropriate by the Project Biologist) for other
passerine birds. Buffer distances for other species will be determined by the
Project Biologist based on the species and its breeding or nesting requirements.
The nest site area shall not be disturbed until the nest becomes inactive or the
young have fledged.
BIO-3: Special-Status Bats. Impacts to special-status bat species would be avoided by
conducting all grading and construction activities outside of the maternity roosting
season (mid-March through August). If maternity roosting season cannot be avoided,
the following measures would be followed.
a. If grading/construction activities must occur during the maternity season, a
qualified biologist shall conduct a pre-construction survey to identify potential
active roosts. The pre-construction survey shall occur the night before
grading/construction activities to observe if any bats are exiting suitable habitat
within 100 feet of the proposed work area. The pre-construction survey will be
conducted at sunset for 90 minutes by a qualified biologist with the use of a
thermal imaging camera to observe and record any bats. If no bats are
observed, work may proceed in the proposed work area the following day and
will remain cleared for the duration of the work activity. If active roosts are
observed, no grading/construction activities may take place in the proposed
work area the following day and not until it can be verified with thermal imaging
that bats have left the area or the maternity roosting season is over.
b. Additional pre-construction surveys will be required in new work areas located
more than 100 feet away from the previously surveyed work area.

Cultural Resources (CR)
CR-1: Archaeological Monitoring. An archaeological monitor (working under the direct
supervision of a Secretary of the Interior-qualified archaeologist [USDI, 2008]) shall be
retained to observe all ground-disturbing activities, including but not limited to brush
clearance, vegetation removal, grubbing, grading, and excavation. Prior to start of
ground-disturbing activities, the archaeologist shall conduct cultural resources sensitivity
training for all construction personnel. Construction personnel shall be informed of the
types of archaeological resources that may be encountered, and of the proper
procedures to be enacted in the event of an inadvertent discovery of archaeological
resources or human remains. The City shall ensure that construction personnel are
made available for and attend the training and retain documentation demonstrating
attendance.
Archaeological monitoring shall be conducted by an archaeologist familiar with the types
of archaeological resources that could be encountered within the project site. The

qualified archaeologist, in coordination with the City, may reduce or discontinue
monitoring if it is determined that the possibility of encountering buried archaeological
deposits is low based on observations of soil stratigraphy or other factors. The
archaeological monitor shall be empowered to halt or redirect ground-disturbing
activities away from the vicinity of a discovery until the qualified archaeologist has
evaluated the discovery and determined appropriate treatment. The archaeological
monitor shall keep daily logs detailing the types of activities and soils observed, and any
discoveries. After monitoring has been completed, the qualified archaeologist shall
prepare a monitoring report that details the results of monitoring. The report shall be
submitted to the City, the Corps, and any Native American groups who request a copy.
A copy of the final report shall be filed at the SCCIC.
If archaeological resources are encountered during monitoring, and if it is determined
that the discovered archaeological resource constitutes a historic property under
Section 106 of the National Historic Preservation Act (NHPA) or a historical resource
under CEQA, avoidance and preservation in place is the preferred manner of treatment.
Preservation in place maintains the important relationship between artifacts and their
archaeological context and also serves to avoid conflict with traditional and religious
values of groups who may ascribe meaning to the resource. Preservation in place may
be accomplished by, but is not limited to, avoidance, incorporating the resource into
open space, capping, or deeding the site into a permanent conservation easement. In
the event that preservation in place is demonstrated to be infeasible and data recovery
through excavation is the only feasible mitigation available, a Cultural Resources
Treatment Plan would be prepared and implemented by a qualified archaeologist in
consultation with the Corps and the City. The plan will provide for the adequate recovery
of the scientifically consequential information contained in the archaeological resource.
The Corps and the City shall be required to consult with appropriate Native American
representatives in determining treatment for prehistoric or Native American resources to
ensure cultural values ascribed to the resource, beyond that which is scientifically
important, are considered.
CR-2: Native American Monitoring. The City shall retain a Native American monitor to
observe all ground-disturbing activities, including but not limited to brush clearance,
vegetation removal, grubbing, grading, and excavation. The Native American monitor
shall be selected from amongst the Native American groups identified by the NAHC as
having affiliation with the project area. The Native American representative shall be
allowed to participate in the cultural resources sensitivity training, discusses in
Mitigation Measure CR-1, and all authorities ascribed to the archaeological monitor,
including the authority to stop work in the event of the discovery of cultural resources,
shall also apply to the Native American monitor. In the event that archaeological

materials are encountered, the Native American monitor shall participate in any
discussions involving treatment and subsequent mitigation.
CR-3: Paleontological Monitoring. A qualified paleontologist meeting the Society for
Vertebrate Paleontology (SVP) guidelines for professional paleontologist (SVP, 2010)
shall be retained to oversee all mitigation measures related to paleontological
resources. That said, both the paleontological and archaeological monitoring could be
carried out by the same person, presuming the monitor is qualified in both disciplines.
During ground disturbing activity, the qualified paleontologist or paleontological monitor
shall conduct spot-checks of exposed sediments. The purpose would be to determine
whether the project would impact the paleontologically sensitive Monterey Formation.
The qualified paleontologist may institute paleontological monitoring if, based on
observations of subsurface stratigraphy or other factors, he or she determines that the
possibility of encountering fossiliferous deposits is high. Paleontological monitoring
would be conducted by a paleontological monitor working under the supervision of the
qualified paleontologist. In the event that monitoring is required, the monitor shall have
the authority to temporarily halt or divert work away from exposed fossils in order to
recover the fossil specimens and shall complete daily monitoring logs outlining the day’s
activities. The qualified paleontologist shall prepare a final monitoring report to be
submitted to the City and filed with the local repository, along with any fossils recovered
during construction.
The qualified paleontologist shall also contribute to any construction worker cultural
resources sensitivity training (see Mitigation Measure CR-1) either in person or via a
training module provided to the qualified archaeologist. The training shall include
information of the types of paleontological resources that may be encountered, and the
proper procedures to be enacted in the event of an inadvertent discovery of
paleontological resources.
In the event of unanticipated discovery of paleontological resources, the City shall
cease ground-disturbing activities within 100 feet of the find until it can be assessed by
the qualified paleontologist. The qualified paleontologist shall assess the find,
implement recovery measures if necessary, and determine if paleontological monitoring
is warranted once work resumes.

Subject: Errata/Revisions to the Initial Study/Mitigated Negative Declaration for the Big Canyon Coastal
Habitat Restoration and Adaptation Project - Phase 2A
Dear Ms. Nova, AICP:
The IS/MND for the Big Canyon Coastal Habitat Restoration and Adaptation Project – Phase 2A was circulated
for public review from September 4, 2018 to October 5, 2018. The City of Newport Beach received four
comment letters, one email and one phone message that included a map.
The following provides the corrections and additions to the sections of the Initial Study/Mitigated Negative
Declaration. The corrections and additions are organized by page number. Additional text is shown in underline,
and deleted text is shown in strikethrough format.

The first sentence in the second paragraph on page 1 of Chapter 1, Introduction of the IS/MND is revised as
follows:
Phase 2A is considered a separate project from other identified phases (i.e. Phase 1, Phase 2B, and Phase 2C)
because where specific grant funding was provided to the project applicant, The Newport Bay Conservancy,
to provide a restoration design for the 11.32-acre project site (Phase 2A).
Page 42, IS/MND
The following correction was required to clarify that the vegetation that is currently infested with the
Polyphagous Shot Hole Borer (PSHB) is some of the existing willow trees. The second paragraph on page 42 of
the IS/MND is revised as follows:
Furthermore, the proposed project includes the removal of the existing Brazilian pepper trees that are
approximately 20 to 30 feet in height, non-native and evergreen. Although these tree species could provide a
visually pleasing view, these species are infested with PSHB that will eventually destroy the trees. The
proposed removal of these non-native evergreen species as well as other exotics and invasive species would
alter distant views from Back Bay Drive and limited views from Jamboree Road, as well as distant eastern
views from the nearest public viewpoint located approximately 600 feet west of the project site within the
western portion of Big Canyon Park. Although these current views would be altered, the proposed vegetation
would provide views of native habitat that can be visually pleasing. the presence of PSHB will result in the
ultimate destruction of the existing pepper trees and the visually pleasing resource will be naturally affected.
Therefore, tThe proposed restoration of the project site with alkali wet and high meadow communities with
vegetation heights of two to three feet would include more sustainable natural plant species. The final project
plantings would continue to provide natural and visually pleasing vegetation as viewed from Back Bay Drive
and Jamboree Road. Although the proposed restoration would alter views from Jamboree Road, Back Bay
Drive, as well as the public viewpoint west of the project site, views of the project site would remain
aesthetically pleasing and impacts to the scenic quality of the project area would be less than significant.

The following correction addresses the comment made by the California Department of Fish and Wildlife who
addressed the need for clarification of vegetation disposal and information provided in third paragraph on page 28
of the IS/MND and page 8 in Appendix C, The Biological Resources Technical Report:
The stream corridor outside of the pepper trees groves is dominated by native willows that exhibited evidence
of infestation by the Polyphagous Shot Hole Borer (PSHB) noted during field surveys conducted during
Phase 1. The potential infested wood chips from the onsite willow trees would be treated through solarization
at locations along the existing trail that are illustrated on Page 6 of the 60% Design Plans in Appendix A. The
remaining wood chips as well as the dead and non-native vegetation would be disposed of at the Prima
Deshecha Landfill. Subsequent to completing the habitat restoration, tThe proposed project will use long-
term pest management techniques in consultation with experts from the University of California Riverside.
Such techniques may include heavy pruning of the existing infested mature trees and application of soil

amendments and tree injections to improve resilience of existing woody plants. These areas also contain
invasive plant species that will be removed selectively and replaced with native plants. To further improve
sustainability of the replanted native riparian vegetation, woody species and herbaceous plants that are not
highly susceptible to PSHB infestation will be selected. Soil amendments will be also used to reduce salinity
levels and improve biological activity in soils. Similarly, the planned re-vegetation after exotic removal along
the creek channel will use a mixed palette of native vegetation that includes smaller stem plants that are less
desirable to the PSHB. Without these management measures, the existing willow trees and proposed riparian
habitat would be likely to be impacted by the PSHB infestation which eventually causes die off of large
mature trees that would provide potentially suitable habitat for important wildlife, including, for example, the
State and federally Endangered least Bell’s vireo (Vireo bellii pusillus).
Page 126, IS/MND
At the end of the second paragraph on page 126 of the IS/MND, the following is revised to address the intended
hours of operation for the Big Canyon Park with the implementation of the proposed project.
Thus, the construction activities associated with the proposed project would be required to adhere to the
applicable permitted hours of operation established under the City of Newport Beach’s Noise Ordinance. In
addition, the City intends to change the hours of operation for Big Canyon Park to close from "dusk till
dawn,” which may require a future ordinance.
Page 141, IS/MND
The following text has been revised to address the landfilling of the chipped material from the project site. The
second paragraph on page 141 of the IS/MND is revised as follows:
Project implementation would result in the need for disposal of vegetative debris from construction
and maintenance activities. Solid waste removed from the project site would include dead or nonnative
vegetation. Debris would be removed with construction equipment and transported to the
landfill by haul trucks at the designated haul routes discussed above in Section 3.4.16, Impacts a)
and d). The total estimated vegetation removal is approximately 7,500 cubic yards and the total
estimated soil removal is approximately 1,500 cubic yards. It is anticipated that the project’s
generation of solid waste would be at its greatest during initial construction activities due to the
primary removal of non-native habitat vegetation. Thereafter, the project would result in minimal
removal of dead vegetation during operational maintenance activities. Chipped material totaling up to
approximately 800 cubic yards may be used for top dressing within the replanted area as well as on the trail
located along the northern boundary of the project site. A portion of the 800 cubic yards of chip material is
anticipated to be infested by the PSHB. Only the potential infested wood chips which are anticipated to come
from some of the onsite willow trees would be treated through solarization at locations along the existing trail
that are illustrated on Page 6 of the 60% Design Plans in Appendix A. The remaining wood chips that are no
infected as well as the dead and non-native vegetation that are also not infected would be disposed of at the
Prima Deshecha Landfill. Given the project’s scale, it is anticipated that the specified landfill would have the
adequate capacity to accommodate the project’s waste disposal needs. Therefore, the project would result in a
less than significant impact to landfill capacity.

Early [10,000 13,000 to 8,000 before present (B.P.)], Millingstone (8,000 to 3,000 B.P.), Intermediate
(3,000 to 1,500 B.P.), and Late Prehistoric (1,500 B.P to A.D. 1769) (Wallace 1955; Warren
1968).
The southern California coast may have been settled as early as 10,000 13,000 years ago (Jones 1992 Waters
and Stafford 2007). Evidence of human occupation as early as 13,000 B.P. was found at the southern
California Fairpoint Site located on Point Dume in Malibu, which was validated by the national museum, The
Smithsonian (Stanford 2007).
