Mitigation Monitoring and
Reporting Program
Introduction
California Public Resources Code, Section 21081.6, requires that, upon certification of an Environmental Impact
Report, “the public agency shall adopt a reporting or monitoring program for the changes made to the project or
conditions of project approval, adopted in order to mitigate or avoid significant effects on the environment. The
reporting or monitoring program shall be designed to ensure compliance during project implementation.”1
This Mitigation Monitoring and Reporting Program has been developed in compliance with Section 21081.6 of the
California Public Resources Code and Section 15097 of the California Environmental Quality Act Guidelines,2 and
includes the following information:
• A list of mitigation measures
• The timing for implementation of the mitigation measures
• The party responsible for implementing or monitoring the mitigation measures
• The date of completion of monitoring
The City of Chula Vista must adopt this Mitigation Monitoring and Reporting Program, or an equally effective
program, if it approves the proposed Sunbow Sectional Planning Area Plan Amendment for the Sunbow II, Phase 3
Project (project) with the mitigation measures that were adopted or made conditions of project approval.

approval and implemented to the satisfaction of the City. The
City’s mitigation monitor shall verify and approve that all
measures identified in the report or mitigation plan are in
place prior to and/or during construction.
To reduce potential impacts to burrowing owl during
construction, the City-approved biologist shall perform pre-
construction inspection of potential habitat, and, at minimum,
twice weekly inspections be performed while rough grading is
ongoing. All pre-construction survey efforts shall be conducted
prior to any project activities that could result in habitat
disturbance to soil, vegetation or other sheltering habitat for
burrowing owl. If any burrowing owls or sign of burrowing owls
are detected, the Wildlife Agencies (jointly, CDFW and USFWS)
shall be contacted; efforts shall be made to determine the
breeding status of the species on site, and whether it is safe
at that point to exclude burrowing owls from occupied
burrows. Active or passive relocation methods shall only be
employed with concurrence by CDFW and USFWS.

Geology and Soils
MM-GEO-1: Paleontological Monitoring Program. Prior to the
issuance of grading permits, the applicant shall provide
written confirmation to the City that a qualified paleontologist
has been retained to carry out an appropriate mitigation
program. (A qualified paleontologist is defined as an individual
with an MS or PhD in paleontology or geology who is familiar
with paleontological procedures and techniques.) A pre-
grading meeting shall be held that shall include the
paleontologist and the grading and excavation contractors.
A paleontological monitor shall be on site at all times during
the original cutting of previously undisturbed sediments of
highly sensitive geologic formations (i.e., Otay Formation and
San Diego Formation) to inspect cuts for contained fossils. (A
paleontological monitor is defined as an individual who has
experience in the collection and salvage of fossil materials.)
The paleontological monitor shall work under the direction of a
qualified paleontologist. The monitor shall be on site on at
least a half-time basis during the original cutting of previously
undisturbed sediments of moderately sensitive geologic
formations (e.g., unnamed river terrace deposits and the
Mission Valley Formation) to inspect cuts for contained fossils.
However, neither of these rock units have been mapped
within the project area of potential effect (APE) and are
therefore not anticipated to be impacted during construction.
The monitor shall be on site on at least a quarter-time basis
during the original cutting of previously undisturbed sediments
of low sensitivity geologic formations (e.g., Lindavista Formation

and Santiago Peak Volcanics [metasedimentary portion only])
to inspect cuts for contained fossils. However, these deposits
have not been mapped within the project APE and are
therefore not anticipated to be impacted during construction.
The monitor shall periodically (every several weeks) inspect
original cuts in deposits with an unknown resource sensitivity
(i.e., Quaternary alluvium).
In the event that fossils are discovered in unknown, low, or
moderately sensitive formations, the Applicant shall increase
the per-day field monitoring time. Conversely, if fossils are not
discovered, the monitoring, at the discretion of the City’s
Deputy City Manager/Development Services Director or its
designee, shall be reduced. A paleontological monitor is not
needed during grading of rocks with no resource sensitivity
(i.e., Santiago Peak Volcanics, metavolcanic portion).
When fossils are discovered, the paleontologist (or
paleontological monitor) shall recover them. In most cases,
this fossil salvage can be completed in a short period of time.
However, some fossil specimens (such as a complete whale
skeleton) may require an extended salvage time. In these
instances, the paleontologist (or paleontological monitor) shall
be allowed to temporarily direct, divert, or halt grading to allow
recovery of fossil remains in a timely manner. Because of the
potential for the recovery of small fossil remains such as
isolated mammal teeth, it may be necessary in certain
instances and at the discretion of the paleontological monitor
to set up a screen-washing operation on the site.
Prepared fossils along with copies of all pertinent field notes,
photos, and maps shall be deposited in a scientific institution
with paleontological collections such as the San Diego Natural
History Museum. A final summary report shall be completed.
This report shall include discussions of the methods used,
stratigraphy exposed, fossils collected, and significance of
recovered fossils.

Wildfire/Hazards and Hazardous Materials
MM-WF-1:
Site Access
Site access, including fire lane, driveway, and entrance road
widths, primary and secondary access, gates, turnarounds,
dead end lengths, signage, aerial fire apparatus access,
surface, and other requirements will comply with the
requirements of the 2019 California Fire Code and the Chula
Vista Fire Department (CVFD) Standards. Fire access will be
reviewed and approved by CVFD prior to construction (see the
FPP, Appendix H3, for additional details).
The developer will provide information illustrating the new
roads, in a format acceptable to the City, for updating of City
maps.
Ignition Resistant Construction
All new structures within the Proposed Project will be
constructed to at least the California Fire Code standard. Each
of the proposed buildings will comply with the enhanced
ignition-resistant construction standards of the 2019 CBC
(Chapter 7A) and Chapter 5 of the Urban-Wildland Interface
code, except where buildings require enhanced ignition
resistance as part of an alternative material and method
proposal. These requirements address roofs, eaves, exterior
walls, vents, appendages, windows, and doors and result in
hardened structures that have been proven to perform at high
levels (resist ignition) during the typically short duration of
exposure to burning vegetation from wildfires (see the FPP,
Appendix H3, for additional details).
Fire Protection Systems

provided for the proposed project.
2. Hydrants shall be located along fire access roadways and
cul-de-sacs as determined by the CVFD Fire Marshal to meet
operational needs. Hydrants will be consistent with CVFD
Design Standards and provided every 500 feet (on-center).
3. All structures within the Proposed Project will include
interior sprinklers, per code requirements (see FPP,
Appendix H3, for additional details). Sprinklers will be
specific to each occupancy type and based on the most
recent National Fire Protection Association (NFPA) 13,
13R, or 13D, requirements.
4. All residential units shall have a fire alarm system be
installed in accordance with NFPA 72, Fire Protection
Signaling System and CVFD requirements. The fire alarm
system will be supervised by a third-party alarm company.
The system will be tested annually, or as needed, with test
results provided to CVFD.
Additionally, all residences will be equipped with residential
smoke detectors and carbon monoxide detectors and comply
with current CBC, CFC, and California Residential Code
standards.
All residential dwelling units shall have electric-powered, hard-
wired smoke detectors with battery backup per CVFD.
Defensible Space and Vegetation Management
Fuel Modification Zones (FMZs) would be located on the
perimeter of all structures and along both ingress/egress
roadways to and from Olympic Parkway. All brush
management zones and related fuel modification activities
shall occur outside of the Preserve. FMZs shall be a minimum
of 100 feet in width. A 100-foot-wide FMZ will be installed for
lots abutting designated Preserve Lands to the north and west
of the Project Site. To ensure long-term identification and

maintenance, each respective FMZ shall be identified by a
permanent marker system meeting the approval of CVFD.
Other Vegetation Management
1. New roads will be subject to fuel modification zones with
Zone 1 and/or Zone 2 standards described above. The
combustible vegetation will be modified within 30 feet
from each side of Streets A and B. Roadway-adjacent fuel
modification does not preclude the planting of street trees
in these fuel modification zones, as long as they are not
found on the Prohibited Plant List (Appendix D of the FPP)
and are included in the Approved Plant Palette (Appendix
C of the FPP).
2. Pre-Construction Requirements:
o Perimeter fuel modification areas must be implemented
and approved by the CVFD prior to combustible
materials being brought on site.
o Existing flammable vegetation shall be reduced by 50%
on vacant lots upon commencement of construction.
o Dead fuel, ladder fuel (fuel which can spread fire from
ground to trees), and downed fuel shall be removed, and
trees/shrubs shall be properly limbed, pruned, and
spaced per this plan.
1. Undesirable Plants. Certain plants are considered to be
undesirable in the landscape due to characteristics that
make them highly flammable. These characteristics can
be physical (structure promotes ignition or combustion) or
chemical (volatile chemicals increase flammability or
combustion characteristics). The plants included in the
Prohibited Plant List (Appendix D of Appendix H3, FPP) are
unacceptable from a fire safety standpoint and will not be
planted on the site or allowed to establish
opportunistically within fuel modification zones or
landscaped areas. No fuel modification zones are

proposed within the MSCP areas, thus no vegetation
within the MSCP will be removed.
2. Tree Notes for Publicly Owned Areas.
The project shall maintain all trees in publicly owned areas,
per the project's FPP. These requirements include, but are not
limited to (see Appendix H3 for additional details):
• All standard form (single trunk) trees to include a single
strong central leader with no branches extending at an
angle narrower than 30 degrees from the main trunk. If
the tree does not display a single strong central leader, a
tree may be approved if the Developer’s arborist or
landscape architect of record can demonstrate that a
single strong central leader can be achieved through
structural pruning.
• No grafted species that sucker from the base stock will be
allowed as a street tree.
1. Vacant Parcels and Lots
The project shall comply with requirements of the project's
FPP related to vacant parcels and lots. These requirements
include, but are not limited to:
• Vegetation management would not be required on vacant
lots until construction begins. However, perimeter FMZs
must be implemented prior to commencement of
construction utilizing combustible materials.
• Vacant lots adjacent to active construction areas/lots
would be required to implement vegetation management
if they are within 50 feet of the active construction area.
Perimeter areas of the vacant lot would be maintained as
a vegetation management zone extending 50 feet from
roadways and adjacent construction areas.
• Prior to issuance of a permit for any construction, grading,
digging, installation of fences, etc., on a vacant lot, the 50
feet at the perimeter of the lot is to be maintained as a
vegetation management zone.

• FMZ on slope L&I does not have to be completed prior to
construction starting, but all flammable vegetation and
plants found on the Prohibited Plant List, needs to
grubbed and graded or mowed prior to any construction.
Fuel Modification Area Vegetation Maintenance
All fuel modification area vegetation management shall be
completed annually by May 1 of each year and more often as
needed for fire safety, as determined by the CVFD.
Annual Fuel Modification Area Vegetation Maintenance
The property owner would obtain an FMZ inspection and
report from a qualified CVFD-approved 3rd party inspector in
May of each year certifying that vegetation management
activities throughout the Project Site have been performed
pursuant to this FPP. A copy of the annual inspection report
would be provided to the proposed project homeowner
association (HOA) and a copy made available to CVFD, if
requested.
Reduced Fuel Modification Zone Discussion
Due to site constraints, it is not feasible to achieve a 100-foot
FMZ width on the south side of the proposed development.
This FPP incorporates additional fire protection measures as
described in this mitigation measure that shall be
implemented to compensate for potential fire related threats.
These measures were customized for this site based on the
analysis results and focus on providing functional equivalency
for reduced defensible space.
Landscape and Building Hardening.

3. Install 1-hour rated walls (Type X- 5/8-inch thickness of
gypsum) behind non-combustible covering (stucco, fiber
cement siding) for a façade facing the open space areas to
the east and south.
4. Conduct a formal landscaping plan review for structures
with a façade facing open space area. Landscape plans
shall be reviewed and approved by the Chula Vista Fire
Department.
5. Annually hire a third-party inspector to evaluate whether
designated fuel modification zone areas meet the
requirements of the project Fire Protection Plan.
6. Provide a non-combustible fire-rated 6-foot-tall masonry
block or view wall at the property line on the south and
east sides of the proposed project to provide a physical,
non-combustible barrier that would deflect heat and flame
and would capture ground-blowing embers before they
reached the proposed project’s developed areas.
The proposed project’s slopes to the south provide an
opportunity to place a non-combustible, 6-foot-tall, heat-
deflecting wall (or view wall with lower 1 to 2 feet block wall
and upper 4 to 5 feet dual-pane, one pane tempered glazing)
to provide additional deflection for these lots to compensate
for the reduced fuel modification zones. The wall shall meet
any of the following specifications:
• Be constructed of multi-pane glazing with a minimum of
one tempered pane meeting the requirements of Section
2406 Safety Glazing, or
• Have a fire-resistance rating of not less than 20 minutes
when tested according to NFPA 257, or
