Variance DRC2018-00566 • The maximum height of walls permitted in residential districts is 6 feet. • Noise attenuation walls are identified as the principal means for mitigating noise impacts generated by traffic on the Foothill Freeway. • Variance to allow the construction of noise attenuating walls along the south, and portions of the east perimeter of the project that will be exceed the 6 foot height limit. • The proposed walls will be approximately 12 to 13.7 feet above the pad elevations of the lots adjacent to the southerly border of the project, which will be approximately 23 feet in height as seen from the south of the project. • Wall height is consistent with the existing wall to the west. Environmental Review • Pursuant to CEQA and the City's local CEQA Guidelines, City staff prepared an Initial Study (IS) of the potential environmental effects of the project. • Based on the findings contained in that IS, we determined that with the imposition of mitigation measures related to Aesthetics, Agricultural Resources, Air Quality, Biological Resources, Cultural Resources, Geology and Soils, Greenhouse Gas Emissions, Hydrology and Water Quality, Noise, and Tribal Cultural Resources there would be no substantial evidence that the project would have a significant effect on the environment. Based on that determination, a Mitigated Negative Declaration (MND) was prepared. • The City provided public notice of the public comment period and of the intent to adopt the Mitigated Negative Declaration. • A Mitigation Monitoring Program has been prepared to ensure implementation of, and compliance with, the mitigation measures for the project. Environmental Review • On August 7, 2018, staff received a comment letter from the San Bernardino County Department of Public Works regarding the IS/MND. • That letter identifies that the project is near the San Bernardino County Flood Control District's Etiwanda Channel facility, and that any proposed activity within the right-of-way would need a Flood Control Permit. • All project improvements are proposed within the project site and no improvements or activity is proposed within the District's right-of-way. Recommendation • Staff recommends the Planning Commission take the following actions: o Adopt the Mitigated Negative Declaration for the project; and o Approve Tentative Tract Map SUBTT19917 and Variance DRC2018-00566 through adoption of the attached Resolutions with Conditions of Approval.

Box 807 Rancho Cucamonga, Ca 91729 Re: Tentative Tract Map SubTT 19917 This letter has been prepared by the Habitat Defense Council ("HDC") in connection with the Tentative Tract Map SubTT 19917 within the City of Rancho Cucamonga ("City"). The HDC is concerned with the preservation and protection of unique natural ecosystems that contain the rich biodiversity that makes the California Floristic Province one of only thirty-five biodiversity hotspots on the planet (Myers 2000; Lamoreux, J. F., et al. 2006; Pimm, S. L., et al. 2014). The California Floristic Province earned inclusion into the original hotspot study for having high rates of endemism (42% of the California Floristic Province's plant species are found nowhere else on the planet, Burge et al. 2016) and being extremely threatened and/or having lost most of its historic species and/or natural ranges. The HDC has identified several legal and technical oversights with the initial study and the intention to adopt a mitigated negative declaration for this particular project. 1. Sensitive Vegetation The biological resource assessment identifies the Prunus llicifolia Shrubland Alliance as being the dominant vegetation community and occupying 3.3 acres of the project site (3.2.1. & Figure 6); it is worth noting that the entire project site, of approximately 7 acres likely contained this vegetation type before the unauthorized grading by KB homes took place. The biological assessment report, however, does not state the fact that the Prunus ilicifolia Shrubland Alliance holds an S3 and a G3 rating per A Manual of California Vegetation, 2nd Ed. (2008)("MCV2"); "Natural Communities with ranks of Sl-S3 are considered Rare and Sensitive Natural Communities to be addressed in the environmental review processes of California Environmental Quality Act and its equivalents" (California Department of Fish and Wildlife, Natural Communities). The omission of the rarity status of this vegetation community is a tremendous oversight and impacts to this vegetation type, however small, should be addressed either through the preparation of an Environmental Impact Report ("EIR") which is recommended, or redetermination to include proper and adequate mitigation and avoidance measures as a part of the Mitigated Negative Declaration. II. Riversidean Alluvial Fan Sage Scrub Important preliminary note: The above section describes the vegetation type according to A Manual of California Vegetation, 2nd Ed. (2008) and should not be confused with the descriptions in this section taken from Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland 1986). These two texts represent two different ways of describing vegetation and while Holland is being used less and less, the biological resource assessment references Holland descriptions and it is therefore addressed in this comment section: "The project site no longer supports RAFSS", as stated in the biological document is false statement for the simple reason that Riversidean alluvial fan sage scrub ("RAFSS") is present on the project site. RAFSS communities vary greatly in form and composition according to stand age as well as other factors. It has been demonstrated that RAFSS is a dynamic habitat that evolves over long periods of time sometimes going hundreds of years without successional reset. Papers produced by Hanes et al, Smith, and Barbour indicate this point well. The paper, Alluvial Scrub Vegetation in Coastal Southern California (Hanes, T.L., et al. 1988) which was referenced in the biological assessment states very clearly that mature alluvial scrub is distinguished by "species commonly found in chaparral or desert plant assemblages, such as California redberry (Rhamnus crocea), mountain mahogany (Cercosarpus beuloides), holly -leaved cherry (Prunus ilicifolia)", all of which occur across the proposed project site. The statement, "the project site no longer supports RAFSS", is a failure of the biological assessment report in that the report content is contradicted by its references. In fact, in section 3.2.2 this point is conceded by the report preparers before linguistic gymnastics are pursued in defining RAFSS in terms of MCV2. To put it simply: using Holland (1986), this area is correctly defined as RAFSS; using MCV2, this area is Prunus ilicifolia Shrubland Alliance (2), which holds a similar sensitive status. Either way, as was mentioned above, impacts to this vegetation type, however small, should be addressed either through the preparation of an EIR and avoided or mitigated for. III. Mandatory Findings of Significance Excerpt from the biological assessment (Summary section iii) regarding CEQA §15065: No federally listed threatened or endangered species were observed or will be impacted by the proposed development. However, impacts to observed sensitive or special status wildlife species could occur, including to those with a high or moderate potential of occurrence, as a result of project implementation. Loss of these individuals will not cause the population to drop below self-sustaining levels or threaten to eliminate a plant or animal community" and is therefore "less -than -significant' under the California Environmental Quality Act (CEQA) (CCR § 21083 CEQA § 15065 Mandatory Findings of Significance). CEQA section 15065 states the parameters that should be used in order to determine whether a lead agency should prepare an EIR. Relevant CEQA sections seemingly not considered in the biological assessment determination are as follows: §15065(a) states that, a lead agency shall find that a project may have a significant effect on the environment and thereby require an EIR to be prepared for the project where there is substantial evidence, in light of the whole record, that any of the following conditions may occur: • §15O65(a) (1) The project has the potential to: substantially degrade the quality of the environment substantially reduce the habitat of a fish or wildlife species; cause o fish or wildlife population to drop below self-sustaining levels,; threaten to eliminate a plant or animal community; substantially reduce the number or restrict the range of an endangered, rare or threatened species; or eliminate important examples of the major periods of California history or prehistory. • § 15065(a)(3) The project has possible environmental effects that are individually limited but cumulatively considerable. "Cumulatively considerable" means that the incremental effects of an individual project are significant when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects. This project threatens to locally eliminate 3 acres of Prunus ilicifolia Shrubland Alliance (S3); adjacent properties were assessed by HDC contract biologist in a good faith effort to determine the existence of any proximity stands of this vegetation type with no success. An EIR is required for any project where it may be fairly argued a project will have a significant impact on the environment. (No Oil, Inc. v. City of Los Angeles, supra, 13 Cal.3d 68, 75,118 Cal.Rptr. 34, 529 P.2d 66; Pub.Resources Code, § 21151.) IV. Recommendations As stated above, this project presents clear significant impacts in the form of (1) destruction of a sensitive vegetation community (2) clear contribution to cumulative impacts to the exceedingly disappearing rare vegetation types of the Etiwanda alluvial fan. A mitigated negative declaration is inappropriate for this project, which on the surface appears to be very obvious piecemeal development. The HDC recommends preparing a full EIR or reexamining mitigation measures to include avoidance or compensatory measure for the Prunus ilicifolia Shrubland. The HDC is grateful for the opportunity to provide comments on this project and is always available to assist private individuals, local governments, public agencies and others in ecologically responsible planning and designing truly effective mitigation measures Habitat Defense Council PO Box 7821 Laguna Niguel, Ca, 92607-7821 References California Department of Fish and Wildlife, Natural Communities. https://www.wildlife.ca,gov/Data/VegCAMP/NaturaI-Communities Hanes, T., R.

AESTHETICS. Would the project. - a) Have a substantial adverse effect on a scenic vista? () () () (✓) b) Substantially damage scenic resources, including, but () () () (✓) not limited to, trees, rock outcroppings, and historic buildings within a State Scenic Highway? c) Substantially degrade the existing visual character or () () () (✓) quality of the site and its surroundings? d) Create a new source of substantial light or glare, which () () (✓) ( ) would adversely affect day or nighttime views in the area? Comments: a) There are no significant vistas within or adjacent to the project site. The site is not within a view corridor according to General Plan Figure LU-6. Therefore, no adverse impacts are anticipated. b) The project site contains no scenic resources and no historic buildings within a State Scenic Highway. There are no State Scenic Highways within the City of Rancho Cucamonga. Therefore, no adverse impacts are anticipated. c) The project site is located on the north side of the 210 Freeway, south of Banyan Street, east of East Avenue, at the southeast corner of the intersection of Gypsum Drive and Raindrop Place and is characterized by existing single-family homes to the north, a tract of single-family homes under construction to the west, the San Sevaine Flood Control Basin to the east, and the 210 Freeway to the south. The proposed project is similar in scale and massing as the existing single-family housing to the north and west and the visual quality of the area will not be degraded as a result of this project. Design review and incorporation of established design guidelines is required prior to approval. City standards require the developer to underground existing and new utility lines and facilities to minimize unsightly appearance of overhead utility lines and utility enclosures in accordance with Planning Commission Resolution No.87-96, unless exempted by said Resolution. There, no adverse impacts are anticipated. d) The project would increase the number of streetlights and security lighting used in the immediate vicinity. The design and placement of light fixtures require compliance with City standards that require shielding, diffusing, or indirect lighting to avoid glare. Lighting will be selected and located to confine the area of illumination to within the project site. Therefore, no adverse impacts are anticipated.

Comments: a) The site is not designated as Prime Farmlands, Unique Farmland, or Farmland of Statewide Importance. The proposed project is located on the north side of the 210 Freeway, south of Banyan Street, east of East Avenue, at the southeast corner of the intersection of Gypsum Drive and Raindrop Place and is characterized by existing single- family homes to the north, a tract of single-family homes under construction to the west, the San Sevaine Flood Control Basin to the east, and the 210 Freeway to the south. The project proposes the subdivision of 7.17 acres into 10 single-family lots. There are approximately 209 acres of Farmland of Local Importance, Prime Farmland, Unique Farmland, or Farmland of Statewide Importance within the City of Rancho Cucamonga according to the General Plan and the California Department of Conservation Farmland Map 2010. Concentrations of Important Farmland are sparsely located in the southern and eastern parts of the City that is characterized by existing and planned development. Farmland in the southern portion of the City is characterized by industrial, residential, and commercial land uses and Farmland in the eastern portion of the City is within the Etiwanda area and planned for development. Further, a large number of the designated farmland parcels are small, ranging from 3 acres to 30 acres, and their economic viability is doubtful; therefore, they are not intended to be retained as farmland in the General Plan Land Use Plan. The General Plan FPEIR identified the conversion of farmlands to urban uses as a significant unavoidable adverse impact forwhich a Statement of Overriding Considerations was ultimately adopted by the City Council. The proposed project is consistent with the General Plan for which the FPEIR was prepared and impacts evaluated. Therefore, no adverse impacts are anticipated. b) There is no agriculturally zoned land within the City of Rancho Cucamonga. There are no Williamson Act contracts within the City. Therefore, no adverse impacts are anticipated.

Therefore, no adverse impacts are anticipated. d) There are no lands within the City of Rancho Cucamonga that qualify as forest land or timberland. No impacts would occur related of the loss or conversion of forest land to non - forest use. Further, there are no areas within the City of Rancho Cucamonga that are zoned as forest land, timberland, or Timberland Production.

Furthermore, there are no lands within the City of Rancho Cucamonga that qualify as forest land and therefore, there is no potential for conversion of forest land to a non -forest use. Therefore, no adverse impacts are anticipated. 3. AIR QUALITY. Would the project: a) Conflict with or obstruct implementation of the () () () (✓) applicable air quality plan? b) Violate any air quality standard or contribute () (✓) () ( ) substantially to an existing or projected air quality violation? c) Result in a cumulatively considerable net increase of () (✓) () ( ) any criteria pollutant for which the project region is non - attainment under an applicable Federal or State ambient air quality standard (including releasing emissions that exceed quantitative thresholds for ozone precursors? d) Expose sensitive receptors to substantial pollutant () (✓) () ( ) concentrations? e) Create objectionable odors affecting a substantial () () () (✓) number of people? Comments: a) As discussed in subsection b, the project would not exceed any air quality standards and would not interfere with the region's ability to comply with Federal and State air quality standards for Criterion 1 Increase in the Frequency or Severity of Violations (local air quality impacts) or Criterion 2 Exceed Assumptions in the AQMP (consistency with the 2003 AQMP). Therefore, the project is consistent with the 2003 AQMP. b) Both the State of California and the Federal government have established health -based ambient air quality standards (AAQS) for seven air pollutants. These pollutants include ozone (03), carbon monoxide (CO), nitrogen dioxide (NOz), sulfur dioxide (S02), coarse Rev 4-17 Initial Study for SUBTT19917 City of Rancho Cucamonga Page 6 Less Than I Significant Less Issues and Supporting Information Potentially Wth Than PP 9 Sources: Significant anp l Miligalion I d Sign, cant t No aaaot particulate matter with a diameter or 10 microns or less (PMto), fine particulate matter less than 2.5 (PM2.5) microns in diameter, and lead. Among these pollutants, ozone and particulate matter (PMio and PM2.5) are considered regional pollutants while the others have more localized effects. In addition, the State of California has set standards for sulfates, hydrogen sulfide (1-12S), vinyl chloride, and visibility reducing particles. These standards are designed to protect the health and welfare of the populace with a reasonable margin of safety. The City of Rancho Cucamonga area is within the South Coast Air Basin, which is under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). The California Clean Air Act (CCAA) provides the SCAQMD with the authority to manage transportation activities at indirect sources. Indirect sources of pollution are generated when minor sources collectively emit a substantial amount of pollution. Examples of this include motor vehicles at an intersection, a mall, and on highways. SCAQMD also regulates stationary sources of pollution within a jurisdictional area. Direct emissions from motor vehicles are regulated by the Air Resources Board (ARB). The combination of topography, low mixing height, abundant sunshine, and emissions from the second largest urban area in the United States gives the Basin the worst air pollution problem in the nation. The Basin experiences a persistent temperature inversion (increasing temperature with increasing altitude); this inversion (coupled with low wind speeds) limits the vertical dispersion of air contaminants, holding them relatively near the ground. Pursuant to the Federal Clean Air Act (FCAA) of 1970, the EPA established national ambient air quality standards (NAAQS) for six major pollutants, termed criteria pollutants: ozone (03), coarse particulate matter with a diameter or 10 microns or less (PMto), fine particulate matter less than 2.5 (PM2.5) microns in diameter, carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and lead. Criteria pollutants are defined as those pollutants for which the Federal and State governments have established AAQS, or criteria, for outdoor concentrations in order to protect public health. Data collected at permanent monitoring stations are used by the EPA to classify regions as "attainment" or "non -attainment" depending on whether the regions met the requirements stated in the primary NAAQS. Nonattainment areas have additional restrictions as required by the EPA. The EPA has designated the Southern California Association of Governments (SCAG) as the Metropolitan Planning Organization (MPO) responsible for ensuring the Basin's compliance with the FCAA. The South Coast Air Basin is in Non -Attainment Status for Ozone, PMio and PM2.5- Specific criteria for determining whether the potential air quality impacts of a project are significant are set forth in the SCAQMD's CEQA Air Quality Handbook. The criteria include daily emissions thresholds, compliance with State and national air quality standards, and consistency with the current AQMP. As prescribed by SCAQMD, an Air Quality and Greenhouse Gas Impact Analysis (Giroux & Associates, March 2015, updated December 2017) was prepared that utilizes CalEEMod (Version 2016.3.2) to evaluate short-term construction emissions and short-term construction emissions for localized significant thresholds, long-term operational emissions, operation emissions for localized significant thresholds, and Greenhouse Gas Emissions. Rev 4-17 Initial Study for SUBTT19917 City of Rancho Cucamonga Page 7 Less Than Significant Less Potentially With Than Issues and Supporting Information Sources: Significant Mitigation Significant No Impact Incarporated Impact Impact Short Term (Construction): Project Emissions and Impacts The project proposes the subdivision of 7.17 acres into 10 single-family lots ranging in size from 23,276 square feet to 26,557 square feet, with an average lot size of 25,078 square feet. These lot sizes exceed both the 20,000 square foot minimum lot size and 25,000 minimum net average lot size requirements of the Etiwanda Specific Plan. The potential emissions associated with construction of the project are described in the following sections.

Exhaust emissions from construction activities envisioned on site would vary daily as construction activity levels change. The use of construction equipment on site would result in localized exhaust emissions; however, as shown in the tables above, the amount will not exceed any threshold of significance. Fugitive Dust Fugitive dust emissions are generally emissions associated with land clearing and exposure of soils to the air and wind, and cut -and -fill grading operations. Dust generated during construction varies substantially on a project -by project basis, depending on the level of activity, the specific operation and weather conditions at the time of construction. Construction emissions can vary greatly depending on the level of activity, the specific Rev 4-17 Initial Study for SUBTT19917 City of Rancho Cucamonga Page 8 Less Than Significant Less Potentially With Than Issues and Supporting Information Sources: Significant Mitigation Significant No Impact Incor orated Impact Impact operations taking place, the equipment being operated, local soils, weather conditions and other factors. The proposed project will be required to comply with SCAQMD Rules 402 and 403 to control fugitive dust. Architectural Coatings Architectural coatings contain VOCs that are similar to ROCS and are part of the 03 precursors. Based on the proposed project, it is estimated that the proposed project will result in a maximum of approximately 11.6 Ibs of VOC per day (combined for all construction sources) during construction. Therefore, this VOC emission is the principal air emission and is less than the SCAQMD VOC threshold of 75 Ibs/day. Odors Heavy-duty equipment in the project area during construction would emit odors. However, the construction activity would cease to occur after individual construction is completed. No other sources of objectionable odors have been identified for the proposed project, and no mitigation measures are required. In compliance with SCAQMD Rule 402 the proposed uses are not anticipated to emit any objectionable odors. Therefore, objectionable odors posing a health risk to potential on -site and existing off -site uses would not occur as a result of the proposed project. Naturally Occurring Asbestos The proposed project is located in San Bernardino County and it is not among the counties that are found to have serpentine and ultramafic rock in their soils. In addition, there has been no serpentine or ultramafic rock found in the project area. Therefore, the potential risk for naturally occurring asbestos (NOA) during project construction is small and less than significant. Based on the discussion above and with implementation of the following Best Available Control Measures (BACM) identified in the Air Quality and Greenhouse Gas Impact Analysis (Giroux & Associates, March 2015, updated December 2017) as mitigation measures, short-term, construction impacts will be less -than -significant: 1) All clearing, grading, earth -moving, or excavation activities shall cease when winds exceed 25 mph per SCAQMD guidelines in order to limit fugitive dust emissions. 2) The contractor shall ensure that all disturbed unpaved roads and disturbed areas within the Project are watered at least three (3) times daily during dry weather. Watering, with complete coverage of disturbed areas, shall occur at least three times a day, preferably in the midmorning, afternoon, and after work is done for the day. 3) The contractor shall ensure that traffic speeds on unpaved roads and Project site areas are reduced to 15 miles per hour or less. Cumulative Impacts: Short -Term Construction Emissions Continued development will contribute to the pollutant levels in the Rancho Cucamonga Rev 4-17 Initial Study for SUBTT19917 City of Rancho Cucamonga Page 9 Less Than Signifcant Less Issues and Supporting Information Sources: Potentially Sgmfi, l wlh Mitigation Than Sfcant No Innipact Incur oraled Im act Im act area, which already exceed Federal and State standards. During the construction phases of development, on -site stationary sources, heavy-duty construction vehicles, construction worker vehicles, and energy use will generate emissions. In addition, fugitive dust would also be generated during grading and construction activities. While mostof the dustwould settle on or near the project site, smaller particles would remain in the atmosphere, increasing particle levels within the surrounding area. Construction is an on -going industry in the Rancho Cucamonga area. Construction workers and equipment work and operate at one development site until their tasks are complete. Nevertheless, fugitive dust and equipment emissions are required to be assessed. The General Plan Final Program Environmental Impact Report (FPEIR) analyzed the impacts of Air Quality based on the future build out of the City. Based upon on the Urban Emissions Model (URBEMIS7G) estimates in Table 4.3-3 of the General Plan (FPEIR), Nitrogen Dioxide (NO2), Ozone (Os), and Particulate Matter (PM2.s and PMto) would exceed SCAQMD thresholds for significance; therefore, they would all be cumulatively considerable if they cannot be mitigated on a project basis to a level less -than -significant. This city-wide increase in emissions was identified as a significant unavoidable adverse impact forwhich a Statement of Overriding Considerations was ultimately adopted by the City Council as noted in the Section 4.3 of the General Plan FPEIR. Based on the Air Quality and Greenhouse Gas Impact Analysis (Giroux & Associates, March 2015, updated December 2017), no short-term, operational impacts would occur as a result of the project. Because the project would result in minimal emissions that do not exceed any thresholds of significance, the project's contribution to cumulative impacts is also considered minimal. With implementation of the following best practices and mitigation measures from the City's 2010 General Plan FPEIR that are designed to minimize short-term air quality impacts, the project's contribution to cumulative impacts will be less -than -significant: 4) All construction equipment shall be maintained in good operating condition so as to reduce operational emissions. The contractor shall ensure that all construction equipment is being properly serviced and maintained as per manufacturers' specifications. Maintenance records shall be available at the construction site for City verification. 5) Prior to the issuance of any grading permits, the developer shall submit construction plans to the City denoting the proposed schedule and projected equipment use. Construction contractors shall provide evidence that low emission mobile construction equipment will be utilized, or that their use was investigated and found to be infeasible for the project. Contractors shall also conform to any construction measures imposed by the South Coast Air Quality Management District (SCAQMD) as well as City Planning Staff. 6) The construction contractor shall utilize electric or clean alternative fuel powered equipment where feasible. 7) The construction contractor shall ensure that construction -grading plans include a statement that work crews will shut off equipment when not in use. 8) All asphalt shall meet or exceed performance standards noted in SCAQMD Rule 1108.

Paints and coatings shall be applied either by hand or high -volume, low-pressure spray. 10) All construction equipment shall comply with SCAQMD Rules 402 and 403. Additionally, contractors shall include the following provisions: • Reestablish ground cover on the construction site through seeding and watering. • Pave or apply gravel to any on -site haul roads. • Phase grading to prevent the susceptibility of large areas to erosion over extended periods of time. • Schedule activities to minimize the amounts of exposed excavated soil during and after the end of work periods. • Dispose of surplus excavated material in accordance with local ordinances and use sound engineering practices. • Sweep streets according to a schedule established by the City if silt is carried over to adjacent public thoroughfares or occurs as a result of hauling. Timing may vary depending upon the time of year of construction. • Suspend grading operations during high winds (i.e., wind speeds exceeding 25mph) in accordance with Rule 403 requirements. • Maintain a minimum 24-inch freeboard ratio on soils haul trucks or cover payloads using tarps or other suitable means. 11) The site shall be treated with water or other soil -stabilizing agent (approved by SCAQMD and Regional Water Quality Control Board (RWQCB)) daily to reduce PM10 emissions, in accordance with SCAQMD Rule 403. 12) Chemical soil -stabilizers (approved by SCAQMD and RWQCB) shall be applied to all inactive construction areas that remain inactive for 96 hours or more to reduce PMIO emissions. Project Long Term (Operational) Emissions and impacts Long-term air pollutant emissions are those associated with stationary sources and mobile sources involving any project -related changes. The proposed project would result in a net increase in the amount of development in the area; therefore, the proposed project would result in net increases in both stationary and mobile source emissions. The stationary source emissions would come from additional natural gas consumption for on -site buildings and electricity for the lighting in the buildings and at the parking area. As shown in the following tables, project implementation will not exceed any significance thresholds. No long-term, operational impacts will occur as a result of the project.

In the long-term, continued development would result in significant operational vehicle emissions based upon on the URBEMIS7G model estimates in Table 4.3-3 of the General Plan FPEIR; therefore, all developments would be cumulatively significant if they cannot be mitigated on a project basis to a less -than -significant level. This City-wide increase in emissions was identified as a significant unavoidable adverse impact for which a Statement of Overriding Considerations was ultimately adopted by the City Council as noted in the Section 4.3 of the General Plan FPEIR. Based on the Air Quality and Greenhouse Gas Impact Analysis (Giroux & Associates, March 2015, updated December 2017), no long-term, operational impacts would occur as a result of the project. Because the project would result in minimal emissions that do not exceed any thresholds of significance, the project's contribution to cumulative impacts is also considered minimal. With implementation of the following mitigation measures from the City's 2010 General Plan FPEIR that are designed to minimize long-term, operational air quality impacts, the project's contribution to cumulative impacts will be less -than - significant: 13) Improve thermal integrity of the buildings and reduce thermal load with automated time clocks or occupant sensors. 14) Landscape with native and/or drought -resistant species to reduce water consumption and to provide passive solar benefits. 15) Provide lighter color roofing and road materials and tree planting programs to comply with the AQMP Miscellaneous Sources MSC-01 measure. 16) All residential structures shall be required to incorporate high- efficiency/low-polluting heating, air conditioning, appliances, and water heaters. 17) All residential structures shall be required to incorporate thermal pane windows and weather-stripping. c) As noted in the General Plan FEIR (Section 4.3), continued development would contribute to the pollutant levels in the Rancho Cucamonga area, which already exceed Federal and State standards. The General Plan FPEIR identified the citywide increase in emissions as Rev 4-17 Initial Study for SUBTT19917 City of Rancho Cucamonga Page 12 Less Than Significant Less Issues and Supporting Information Sources: Potentially Signlrcent With Mitigation Than SlgniBcanl No Im act Incur orafetl Im act Im act a significant and adverse impact for which a Statement of Overriding Considerations was ultimately adopted by the City Council. With implementation of mitigation measures listed in subsection b) above from the City's 2010 General Plan FPEIR, which are designed to minimize long-term, operational air quality impacts, cumulative impacts will be less -than -significant. d) Sensitive receptors are defined as populations that are more susceptible to the effects of pollution than the population at large. The SCAQMD identifies the following as sensitive receptors: long-term health care facilities, rehabilitation centers, convalescent centers, retirement homes, residences, schools, playgrounds, child care centers, and athletic facilities. According to the SCAQMD, projects have the potential to create significant impacts if they are located within 1/4 mile of sensitive receptors and would emit toxic air contaminants identified in SCAQMD Rule 1401. The project site is located within % mile of a sensitive receptor. There are existing residences immediately west and adjacent to the project site; however, as the proposed project is a single family residential development, it will not generate toxic air contaminants. During construction, there is the possibility of fugitive dust to be generated from grading the site. The mitigation measures listed under subsection b above and the following mitigation measure will reduce any potential impact to less -than -significant levels. 18) All new development in the City of Rancho Cucamonga shall comply with South Coast Air Quality Management District's Rule 445, Wood Burning Devices. Rule 445 was adopted in March 2008 to reduce emissions of PM2.5 and precludes the installation of indoor or outdoor wood burning devices (i.e. fireplaces/hearths) in new development on or after March 9, 2009. e) Construction odors (Short-term) may include odors associated with equipment use including diesel exhaust or roofing, painting and paving. These odors are temporary and would dissipate rapidly. Operational odors (Long-term) are typically associated with the type of use. Odors from the proposed single-family residential use would most likely be from activities such as cooking; however, these odors would be minimal and not considered to be significant. No adverse impacts are anticipated. 4. BIOLOGICAL RESOURCES.
