Mitigation Monitoring and Reporting Program
Section 21081.6 of the California Environmental Quality Act ( CEQA) Guidelines requires that a Mitigation Monitoring and Reporting Program (MMRP) be adopted upon certification of an Environmental Impact Report ( EIR) to ensure that the mitigation measures are implemented. The MMRP specifies the mitigation measures that have been identified to address potential impacts that would result from adoption of the City of Chino (City) 2045 General Plan Update (project) and future site-specific development. The MMRP additionally identifies the entity responsible for implementing and/or monitoring the mitigation; and when in the process it should be accomplished.
The Program EIR (PEIR) prepared for the project focuses on issues determined to be potentially significant by the City. The issues addressed in the PEIR include aesthetics, air quality, biological resources, cultural and tribal cultural resources, geology and soils, greenhouse gas (GHG) emissions, hazards and hazardous materials, hydrology and water quality, land use and planning, noise, population and housing, public services and recreation, transportation, utilities and service systems, and wildfire.
Public Resources Code Section 21081.6 requires monitoring of only those impacts identified as significant or potentially significant. After analysis, potentially significant impacts were identified for air quality, biological resources, cultural and tribal cultural resources, geology and soils, GHG emissions, noise, and transportation.
Implementation of the mitigation measures identified in this PEIR would reduce potentially significant impacts, but not to below a level of significance for all the environmental issue areas. Mitigation measures have been identified for significant impacts related to air quality (air quality plans; criteria pollutants; sensitive receptors), biological resources (special status species, sensitive riparian habitats, jurisdictional wetlands and waters ), cultural and tribal cultural resources (historic resources ; archaeological resources; tribal cultural resources) , geology and soils (paleontological resources), GHG emissions (GHG emissions; policy consistency), and noise (ambient noise [traffic noise/land use compatibility/stationary noise/construction noise] ; groundborne noise and vibration) . No feasible mitigation was identified for impacts to transportation (circulation system: roadway system vehicle miles traveled). Impacts related to air quality (air quality plans; criteria pollutants; sensitive receptors), cultural and tribal resources (historic resources), greenhouse gas (emissions; policy consistency), noise ( ambient noise: traffic noise/land use compatibility ; groundborne noise and vibration:
construction), and transportation (circulation system: roadway system; vehicle miles traveled) would remain significant and unavoidable at the program level.
The MMRP for the project is under the jurisdiction of the City . As specified in Table 1, t he MMRP summarizes the potentially significant impacts and lists the associated mitigation measures and the monitoring efforts necessary to ensure that the measures are properly implemented.

Issue 1: Conflict with Air Quality Plan:
Construction Emissions
AQ-1: Construction Air Quality
Applications for future development and redevelopment, wherein the City’s Director of the Development Services Department or their designee has determined a potential for air quality impacts associated with construction, shall prepare and submit a technical assessment evaluating potential project construction-related air quality impacts to the City for review and approval. The City’s Director of the Development Services Department or their designee shall make this determination based on the size of the project, whether the project would require a transportation impact analysis, or other criteria. The evaluation shall be prepared in conformance with SCAQMD methodology for assessing air quality impacts. The City shall require that applicants for new development projects with the potential to exceed the SCAQMD’s adopted thresholds of significance to incorporate the measures listed below to reduce air pollutant emissions during construction activities. These identified measures shall be incorporated into all appropriate construction documents (e.g., construction management plans) submitted to the City and shall be verified by the City.
Mitigation measures to reduce construction-related emissions could include, but are not limited to:
• During all construction activities, construction contractors shall use low emission mobile construction equipment where feasible to reduce the release of undesirable emissions.
• During all construction activities, construction contractors shall encourage rideshare and transit programs for project construction personnel to reduce automobile emissions.
• During all grading and site disturbance activities, construction contractors shall water active grading sites at least twice a day, and clean construction equipment in the morning and/or evening to reduce particulate emissions and fugitive dust.
• During all construction activities, construction contractors shall, as necessary, wash truck tires leaving the site to reduce the amount of particulate matter transferred to paved streets as required by SCAQMD Rule 403.
• During all construction activities, construction contractors shall sweep on- and off-site streets if silt is carried over to adjacent public thoroughfares, as determined by the City Engineer to reduce the amount of particulate matter on public streets.

• During all construction activities, construction contractors shall limit traffic speeds on all unpaved road surfaces to 15 mph or less to reduce fugitive dust.
• During grading and all site disturbance activities, at the discretion of the City’s Director of the Development Services Department, construction contractors shall suspend grading operations during first and second stage smog alerts to reduce fugitive dust.
• During grading and all site disturbance activities, at the discretion of the City’s Director of the Development Services Department, construction contractors shall suspend all grading operations when wind speeds (including instantaneous gusts) exceed 25 mph to reduce fugitive dust. • During all construction activities, the construction contractors shall maintain construction equipment engines by keeping them tuned.
• During all construction activities, the construction contractors shall use low sulfur fuel for stationary construction equipment as required by SCAQMD Rules 431.1 and 431.2 to reduce the release of undesirable emissions. • During all construction activities, the construction contractors shall use existing on-site electrical power sources to the maximum extent practicable. Where such power is not available, the Contractor shall use clean fuel generators during the early stages of construction to minimize or eliminate the use of portable generators and reduce the release of undesirable emissions.
• During all construction activities, the construction contractors shall use low emission, on site stationary equipment (e.g., clean fuels) to the maximum extent practicable to reduce emissions, as determined by the City Engineer. • During all construction activities, the construction contractors, in conjunction with the City Engineer, shall locate construction parking to minimize traffic interference on local roads.
• During all construction activities, the construction contractors shall ensure that all trucks hauling dirt, sand, soil or other loose materials are covered or should maintain at least two feet of freeboard (i.e., minimum vertical distance between top of the load and the top of the trailer) in accordance with the requirements of the California Vehicle Code Section 23114 to reduce spilling of material on area roads.
• During architectural coating activities, use Super-Compliant VOC paints for coating of architectural surfaces whenever possible. A list of

Issue 1: Conflict with Air Quality Plan:
Operational Emissions
AQ-2: Operational Air Quality
Applications for future development and redevelopment, wherein the City’s Director of the Development Services Department or their designee has determined a potential for air quality impacts associated with operation, shall prepare and submit a technical assessment evaluating potential project operational-related air quality impacts to the City for review and approval. For individual projects that may exceed the daily operational emissions thresholds established by the SCAQMD, the owner/permitee shall conduct an analysis of the project’s operational air quality impacts using the latest available CalEEMod mode, or other analytical method determined in conjunction with the City. The City’s Director of the Development Services Department or their designee shall make this determination based on the size of the project, whether the project would require a transportation impact analysis, or other criteria. The evaluation shall be prepared in conformance with SCAQMD methodology for assessing air quality impacts. If such analyses identify potentially significant regional or local air quality impacts, project-level mitigation and/or project design features would be required to reduce operational impacts to less than significant. Mitigation to reduce operational impacts depends on the specific project, but may include measures such as, but not limited to:
• Demonstrate net zero energy expenditure.
• Implementation of transportation demand management measures. • Prohibit the installation of woodstoves, hearths, and fireplaces in new construction facilitated by the General Plan Update.
• Expand and facilitate completion of planned networks of active transportation infrastructure.
• Implement electric vehicle charging infrastructure beyond requirements set forth in the 2022 CALGreen mandatory measures, such as Tier 2 voluntary measures set forth in 2022 CALGreen (or future more stringent) standards. • Implement traffic demand measures, such as unbundling parking fees from rent/lease options, encouraging/developing a ride-share program for the community, and provide car/bike sharing services, that will reduce daily individual car usage and reduce project VMT.

Applications for future development, wherein the City’s Director of Development Services or their designee has determined a potential for impacts to mature trees and/or native vegetation suitable for nesting birds, shall be required to restrict removal of sensitive habitat and vegetation to outside the breeding seasons of any sensitive species identified within adjacent properties (typical bird breeding season is January 15 to September 15, as early as January 1 for some raptors). If vegetation clearing must begin during the breeding season, a qualified biologist shall provide recommendations to avoid impacts to nesting birds which typically includes a pre-construction survey within three days of the start of construction to determine the presence of active nests.
If active nests are found, avoidance measures shall be implemented to ensure protection of the nesting birds. Avoidance measures may include a no-activity buffer zone, typically 300 feet from the area of disturbance or 500 feet for raptors, established at the discretion of the qualified biologist in consultation with the City, If activity buffer zones are not feasible, temporary noise barriers may be installed to attenuate construction noise. Noise wall height and adequacy shall be supported by a noise analysis to determine the anticipated construction noise levels with attenuation measures as recommended by the biologist and approved by the City. Periodic noise monitoring shall be conducted during construction to ensure noise attenuation standards are met. Accepted noise levels are species dependent and existing ambient noise levels can play a factor in establishing baseline acceptable noise.

Cultural Resources
Issue 1: Historic Resources CUL-1: Historic Evaluation
Prior to approval of a future site-specific project that would directly or indirectly affect a building/structure in excess of 50 years of age, the City or a qualified architectural historian shall determine whether the affected building/structure is historically significant. The evaluation shall be based on criteria such as age, location, context, association with an important person or event, uniqueness, or structural integrity, as indicated in the CEQA guidelines. If the evaluation determines that building/structure is not historic, no further evaluation or mitigation would be required. If the building/structure is determined to be historically significant, the preferred mitigation would be to avoid the resource through project redesign. If the resource cannot be avoided, all prudent and feasible measures to minimize or mitigate harm to the resource shall be taken per recommendations of the qualified architectural historian.

Greenhouses Gas Emissions
Issue 1: GHG Emissions GHG-1: Greenhouse Gas
All future site-specific projects shall be required to demonstrate consistency with the City’s CAP. As stated in Appendix A of the CAP, analysis of site-specific projects can either be done through emissions calculations or by using the Screening Tables. Site-specific projects that obtain at least 100 points would be consistent with the reduction quantities anticipated in the CAP. Those site-specific projects that do not obtain 100 points using the Screening Tables would need to provide additional analysis to determine the significance of GHG emissions.
Per Section 15.45.070 of the City’s Municipal Code, GHG Performance Standards for New Development, all new development not utilizing the Screening Tables shall contribute to the reduction of GHG emissions by demonstrating consistency with the CAP by implementing one or a combination of the following three options:
1. Exceed the mandatory California Energy Code Title 24, Part 6 standards, in effect at the time of application submittal by five percent; or
2. Achieve an equivalent reduction through voluntary measures in the California Green Building Standards Code, Title 24, Part 11 (CALGreen) in effect at the time of development application submittal for discretionary review; or
3. Provide other equivalent GHG reductions through measures including, but not limited to, non-vehicle transportation infrastructure, transit, ZEV (zero emission vehicle) infrastructure or other incentives, waste diversion, water conservation, tree planting, renewable energy option packages, or any combination of these or other measures such that GHG emissions are reduced by 0.074 MT CO
2E per residential dwelling unit per year and/or
per thousand square feet of commercial/industrial use per year.
Applicants that choose Option 1 described above would be required to verify that their site-specific project meets the five percent improvement above the mandatory standards through the appropriate certificate of compliance form for residential construction (CF-1R) or for commercial/industrial construction (PERF- 1C). Applicants that choose Options 2 or 3 described above would be required to utilize the GHG Performance Standard Checklist developed by the City, or provide other valid documentation, such as CalEEMod or other methodologies, as verified by the director of development services to demonstrate the required GHG reductions consistent with the City's CAP.

Construction contractors shall implement the following measures for construction activities conducted in the Planning Area. These measures shall be identified on demolition, grading, and construction plans submitted to the City:
• The City’s Development Services Department shall verify that grading, demolition, and/or construction plans submitted to the City include these notations prior to issuance of demolition, grading, and/or building permits. • Construction activity is limited to the hours: Between 7:00 a.m. and 8:00 p.m. Monday through Saturday as prescribed in Municipal Code Section
15.44.030. No construction activities shall be permitted outside of these hours or on Sundays and federal holidays.
• During the entire active construction period, equipment and trucks used for project construction shall use the best-available noise control techniques (e.g., improved mufflers, equipment redesign, use of intake silencers, ducts, engine enclosures, and acoustically attenuating shields or shrouds), wherever feasible.
• Impact tools (e.g., jack hammers and hoe rams) shall be hydraulically or electrically powered wherever possible. Where the use of pneumatic tools is unavoidable, an exhaust muffler on the compressed air exhaust shall be used along with external noise jackets on the tools.
• Stationary equipment, such as generators and air compressors shall be located as far as feasible from nearby noise sensitive land uses. • Stockpiling shall be located as far as feasible from nearby noise sensitive land uses.
• Construction traffic shall be limited, to the extent feasible, to approved haul routes established by the City’s Development Services Department. • At least 10 days prior to the start of construction activities, a sign shall be posted at the entrance(s) to the job site, clearly visible to the public, that includes permitted construction days and hours, as well as the telephone numbers of the City’s and contractor’s authorized representatives that are assigned to respond in the event of a noise or vibration complaint.

authorized contractor’s representative receives a complaint, he/she shall investigate, take appropriate corrective action, and report the action to the City.
• Signs shall be posted at the job site entrance(s), within the on-site construction zones, and along queueing lanes (if any) to reinforce the prohibition of unnecessary engine idling. All other equipment shall be turned off if not in use for more than 5 minutes.
• During the entire active construction period and to the extent feasible, the use of noise-producing signals, including horns, whistles, alarms, and bells, shall be for safety warning purposes only. The construction manager shall use smart backup alarms, which automatically adjust the alarm level based on the background noise level or switch off backup alarms and replace with human spotters in compliance with all safety requirements and laws. • Erect temporary noise barriers (at least as high as the exhaust of equipment and breaking line-of-sight between noise sources and sensitive receptors), as necessary and feasible, to maintain construction noise levels at or below the noise level limits established in the Municipal Code.
Issue 2: Groundborne Noise and

NOI-5: Construction Vibration
Prior to issuance of a building permit for a project requiring pile driving during construction within 135 feet of fragile structures, such as historical resources, 100 feet of non-engineered timber and masonry buildings (e.g., most residential buildings), or within 75 feet of engineered concrete and masonry (no plaster); or a vibratory roller within 25 feet of any structure, the project applicant shall prepare a noise and vibration analysis to assess and mitigate potential noise and vibration impacts related to these activities. This noise and vibration analysis shall be conducted by a qualified and experienced acoustical consultant or engineer. The vibration levels shall not exceed FTA architectural damage thresholds (e.g., 0.12 in/sec PPV for fragile or historical resources, 0.2 in/sec PPV for non-engineered timber and masonry buildings, and 0.3 in/sec PPV for engineered concrete and masonry). If vibration levels would exceed this threshold, alternative uses such as drilling piles as opposed to pile driving and static rollers as opposed to vibratory rollers shall be used. If necessary, construction vibration monitoring shall be conducted to ensure vibration thresholds are not exceeded.
