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 Prior to and during construction City of Chula Vista Mitigation Monitoring and Reporting Program Sunbow Sectional Planning Area Plan Amendment for the Sunbow II, Phase 3 Project EIR 12612 July 2021 MMRP-15 Table 1. Mitigation Monitoring and Reporting Program Mitigation Measure Implementation Timing Agency Responsible for Monitoring Date of Completion 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.

Water supply requirements specified in the California Fire Code (see FPP, Appendix H3, for additional details) During construction and operation City of Chula Vista Mitigation Monitoring and Reporting Program Sunbow Sectional Planning Area Plan Amendment for the Sunbow II, Phase 3 Project EIR 12612 July 2021 MMRP-20 Table 1. Mitigation Monitoring and Reporting Program Mitigation Measure Implementation Timing Agency Responsible for Monitoring Date of Completion including for hydrants and interior sprinklers will be 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 Mitigation Monitoring and Reporting Program Sunbow Sectional Planning Area Plan Amendment for the Sunbow II, Phase 3 Project EIR 12612 July 2021 MMRP-21 Table 1. Mitigation Monitoring and Reporting Program Mitigation Measure Implementation Timing Agency Responsible for Monitoring Date of Completion 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 Mitigation Monitoring and Reporting Program Sunbow Sectional Planning Area Plan Amendment for the Sunbow II, Phase 3 Project EIR 12612 July 2021 MMRP-22 Table 1. Mitigation Monitoring and Reporting Program Mitigation Measure Implementation Timing Agency Responsible for Monitoring Date of Completion 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. Mitigation Monitoring and Reporting Program Sunbow Sectional Planning Area Plan Amendment for the Sunbow II, Phase 3 Project EIR 12612 July 2021 MMRP-23 Table 1. Mitigation Monitoring and Reporting Program Mitigation Measure Implementation Timing Agency Responsible for Monitoring Date of Completion • 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. 1. Provide exterior glazing in windows (and sliding glass doors, garage doors, or decorative or leaded glass doors) facing the open space areas to be dual pane with both Mitigation Monitoring and Reporting Program Sunbow Sectional Planning Area Plan Amendment for the Sunbow II, Phase 3 Project EIR 12612 July 2021 MMRP-24 Table 1. Mitigation Monitoring and Reporting Program Mitigation Measure Implementation Timing Agency Responsible for Monitoring Date of Completion panes tempered glass, exceeding the fire-building code requirement. 2. Ensure no eave overhangs and combustible construction in portion of yards facing natural open space areas. 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 Mitigation Monitoring and Reporting Program Sunbow Sectional Planning Area Plan Amendment for the Sunbow II, Phase 3 Project EIR 12612 July 2021 MMRP-25 Table 1. Mitigation Monitoring and Reporting Program Mitigation Measure Implementation Timing Agency Responsible for Monitoring Date of Completion • Be tested to meet the performance requirements of SFM Standard 12-7A-2. Homeowner’s Wildfire Education Program Per the FPP, the proposed project’s residents shall be provided a proactive educational component disclosing the potential wildfire risk and this report’s requirements as part of their purchase documents. Property owners shall be required to sign notice of receiving this information during escrow. This educational information must include maintaining the landscape and structural components according to the appropriate standards and embracing a “Ready, Set, Go” stance on evacuation.
