Agenda packet — Ontario City Council, November 4, 2025 (part 4 of 15)

construction requirements would minimize odor impacts from construction. The construction odor emissions would be temporary, short-term, and intermittent in nature and would cease upon completion of the respective phase of construction and is thus considered less than significant.

Project-generated refuse would be stored in covered containers and removed at regular intervals in compliance with the City’s solid waste regulations. The Project would also be required to comply with SCAQMD Rule 402 to prevent occurrences of public nuisances. Therefore, odors associated with the Project construction and operations would be less than significant. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

4. BIOLOGICAL RESOURCES. Would the project:
a. Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service?
Summary of Certified SEIR Finding: The Certified SEIR recognizes that development in accordance with TOP 2050 could impact sensitive species. Projects considered for approval under TOP 2050 would be subject to independent CEQA review to determine whether there is potential habitat on-site for sensitive species. The Certified SEIR did not identify any significant impacts in this regard (Certified SEIR, pp. 5.4-28 – 5.4-34).

Project Impacts: A General Biological Resources Assessment was conducted for the entire Esperanza Specific Plan area, inclusive of the Project site, as part of the Esperanza DEIR. The Assessment concluded that no natural or native plant communities were present within the Specific Plan area, and only a few scattered remnants of native vegetation remained due to long-standing agricultural uses.

No special-status plant species were identified within the Specific Plan area, nor were any expected to occur due to the overall absence of suitable habitat.

Several special-status wildlife species were either recorded during the Assessment or had the potential to occur within the Specific Plan area. These species included the loggerhead shrike (Lanius ludovicianus), burrowing owl (Athene cunicularia), white-tailed kite (Elanus leucurus), Northern harrier (Circus cyaneus), Ferruginous hawk (Buteo regalis), Golden eagle (Aquila chrysaetos), California horned lark (Eremophila alpestfis actia), and the San Diego black-tailed jackrabbit (Lepus californicus benettii). Impacts to these species, and potential foraging/nesting habitat within the Specific Plan area, were reduced to less than significant through the application of mitigation.

All mitigation measures protecting biological resources required of the Esperanza Specific Plan (see Appendix B) would be implemented by the Project, precluding the Project’s potential to have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

c. Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?
Summary of Certified SEIR Finding: The Certified SEIR concluded that individual projects subject to CEQA environmental review would be required to determine whether there is potential habitat on-site for sensitive species. The Certified SEIR did not identify any significant impacts in this regard (Certified SEIR, p. 5.4-28).

Project Impacts: The Esperanza Specific Plan DEIR concluded that no riparian or wetlands were located within the Specific Plan area, inclusive of the Project site.

The site is surrounded by roadways, including gutters. No drainage courses or streams exist within the Project site. Therefore, the Project would not result in significant impacts to riparian habitat, wetlands, or other sensitive natural communities. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Mitigation:

Certified SEIR Measure(s) Project Applicability
None. -
d. Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?
Summary of Certified SEIR Finding: The Certified SEIR states that no regional wildlife movement corridors have been identified in the City, and most of the City is illsuited for the purposes of wildlife movement. Additionally, compliance with existing policies and regulations ensures impacts in this regard would be maintained at levels that would be less than significant (Certified SEIR, p. 5.4-30). 805
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Page 57 of 152 ends

Project Impacts: No wildlife corridors or linkages are located on-site. Further, the site is bounded on all sides by roads and/or urban development, diminishing its potential to function as a wildlife movement corridor. Consistent with the conclusion of the Certified SEIR, the Project would not interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors or impede the use of native wildlife nursery sites. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Mitigation:

Certified SEIR Measure(s) Project Applicability

e. Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? f. Conflict with the provisions of an adopted Habitat Conservation Plan (HCP), Natural Community Conservation Plan (NCCP), or other approved local, regional, or state habitat conservation plan?
Summary of Certified SEIR Finding: The Certified SEIR did not identify any conflicts with any local policies or ordinances protecting biological resources, adopted Habitat Conservation Plan, Natural Community Plan, or other approved local, regional, or state habitat conservation plan (Certified SEIR, pp. 5.4-30 – 5.4-31).

Project Impacts: Section 10-2 of the Ontario Municipal Code addresses tree protection, maintenance, and replacement policies for trees within the City’s parkways and rights-of-way. Additionally, the City has published landscape guidelines that must be followed when developing new or existing sites. The Project would be implemented consistent with all applicable guidelines in this regard.

Page 58 of 152 ends

The Project site is not part of an adopted HCP, NCCP or other approved habitat conservation plan (CDFW, 2019). As a result, no adverse environmental impacts are anticipated. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

5. CULTURAL RESOURCES. The analysis in this section is based on the following technical analysis:
• Cultural Resources Study for the Eucalyptus and Amherst Avenues Project, City of Ontario, San Bernardino County, California (BFSA Environmental Services) April 1, 2025.

The report (BFSA, 2025a) is provided in its entirety as Appendix D of this Addendum.
a. Cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5?
Summary of Certified SEIR Finding: Historic resources in the City include historic districts, historic landmarks or points of historical interest, and other buildings, structures, objects, and sites that appear eligible for listing on the National, California, or Local Registers of Historic Places. The Certified SEIR concluded that adoption of TOP 2050 would not itself directly affect any historical structures; however, identified and potential historic structures and sites may be vulnerable as development occurs. Mitigation Measure 5-1 would require historic or potentially historic resources to be evaluated for historic significance through the City’s Development Code tier system. Impacts to historical resources would remain significant and unavoidable (Certified SEIR, pp. 5.5-18 – 5.5-23). 807
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Page 59 of 152 ends

Project Impacts: No on-site historical resources were identified as part of the Project-specific Cultural Resources Study. The Cultural Resources Study concluded that no further study or mitigation would be required (BFSAa, 2025).

Therefore, the Project would not cause a substantial adverse change in the significance of a historical resource as defined in Section 15064.5, and no impacts would occur. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

7.01.050 (Unsafe or Dangerous
Conditions) of this Development
Code.

In an effort to preserve features and
artifacts from historic resources, a
determination whether items within or
on the resource should be salvaged
must be made by the Planning
Department and may include the
local historical society prior to the
issuance of the demolition permit. The

include a list of each item name,
description, and dimension (as
necessary), and the location of each
item on a floor plan.
b. Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5?
Summary of Certified SEIR Finding: Adoption of TOP 2050 would not of itself directly affect archaeological resources. However, buildout of TOP 2050 land use plan would allow development activities and ground disturbance affecting known and potential areas of archaeological sensitivity. These activities could potentially cause the disturbance of archeological resources. Therefore, future development that would be accommodated by TOP 2050 could potentially unearth previously unrecorded resources; see Mitigation Measure 5-2, below. (Certified SEIR, p. 5.5- 19).

Project Impacts: No cultural resources were identified within the Project site during the Cultural Resources Study. Further, no natural resources associated with archaeological sites, such as natural water sources or bedrock outcroppings are present within the Project site. Due to the prior ground disturbance and the 810
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Page 62 of 152 ends

absence of identified cultural resources within the Project site vicinity, the potential for any significant resources to be present or impacted by the Project was determined to be minimal. Given that no archaeological sites, features, or artifacts have been identified within or directly adjacent to the Project site, the Cultural Resources Study determined that no potential impacts to cultural resources are anticipated. The Cultural Resources Study concluded that no further archaeological study or mitigation would be required (BFSA, 2025a).

The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Mitigation:

for permanent curation; and provide a
comprehensive final report including a
catalog with museum numbers.
c. Disturb any human remains, including those interred outside of dedicated cemeteries?
Summary of Certified SEIR Finding: The Certified SEIR concluded that compliance with existing regulations would ensure that the potential for TOP 2050 to disturb any human remains, including those interred outside of formal cemeteries was less than significant (Certified SEIR, p. 5.5-21).

Project Impacts: The Project would be required to comply with all existing regulations, including the California Public Resources Code Section 5097.98, which would provide protection for any human remains discovered during development activities. On this basis, the potential for the Project to result in disturbance of any human remains, including those interred outside of formal cemeteries would be less than significant. When compared to the Certified SEIR findings, no new or substantially increased impacts related to potential disturbance of human remains would result from the Project. 812

6. ENERGY. Would the project:
a. Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation?
Summary of Certified SEIR Finding: The Certified SEIR concluded that regulatory compliance under TOP 2050 buildout conditions would promote building energy efficiency and vehicle fuel efficiency and reduce building energy demand and transportation-related fuel usage. Additionally, TOP 2050 includes policies related to land use and transportation planning and design, energy efficiency, public and active transit, and renewable energy generation that would contribute to enhanced building and transportation-related energy efficiencies and thereby reduce demands on nonrenewable sources of energy. Implementation of TOP 2050 Policies, energy efficiency and conservation measures articulated in the Community Climate Action Plan (CCAP), and compliance with regulatory requirements would ensure that energy consumption resulting from TOP 2050 buildout would not be inefficient, wasteful, or unnecessary. On this basis, the potential for TOP 2050 to result in a potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources would be less than significant (Certified SEIR, pp. 5.6-9 – 5.6-12).

Project Impacts: The Project would be implemented consistent with all applicable regulations in this regard, including applicable efficiency/conservation provisions of the CCAP and applicable CCAP updates. Additionally, the Project would adhere to all applicable TOP 2050 policies related to land use and transportation planning and design, energy efficiency, public and active transit, and renewable energy generation that would contribute to enhanced building and transportation-related energy efficiencies and thereby reduce demands on nonrenewable sources of energy. Based on the preceding, the Project would not 813

When compared to impacts addressed in the Certified SEIR, no new or substantially increased energy impacts would occur under the Project.

Mitigation:

b. Conflict with or obstruct a state or local plan for renewable energy or energy efficiency?
Summary of Certified SEIR Finding: The Certified SEIR notes that TOP 2050 would comply with applicable provisions of the California Renewables Portfolio Standard Program (RPS); and current and future iterations of CALGreen.

Additionally TOP 2050 includes policies supporting statewide goals to transition the electricity grid to renewable sources. Mandated compliance with the CCAP and its updates would also be required for all new development under TOP 2050. On this basis, the Certified SEIR concluded that the potential for TOP 2050 to conflict with or obstruct a state or local plan for renewable energy or energy efficiency would be less than significant (Certified SEIR, pp. 5.6-13, 5.6-14).

Project Impacts: The Project would be required to comply with incumbent Building Energy Efficiency Standards contained in the California Code of Regulations (CCR), Title 24, Part 6, Energy Efficiency Standards, including applicable CALGreen provisions. CALGreen supports the goals of the State’s greenhouse gas reduction and building energy efficiency programs. The Project would also be required to implement applicable energy efficiency/conservation measures of the CCAP and its updates. Based on the preceding, the Project would not conflict with or obstruct a state or local plan for renewable energy or energy efficiency.

7. GEOLOGY & SOILS. The following discussions are based primarily on information presented in the following analyses:
• Geotechnical Evaluation of Mass Graded Site and Grading Plan Review of Proposed 10-Acre “Esperanza Townhomes” Residential Development, Buildings 1 through 28, Tentative Tract No. 20730, located North of Eucalyptus & Amherst Avenues, City of Ontario, County of San Bernardino, California (LGC Geotechnical, Inc.) April 18, 2025.
• Paleontological Assessment for the Eucalyptus and Amherst Avenues Project, City Of Ontario, San Bernardino County, California (BFSA Environmental Services) April 1, 2025.

These reports are presented as Appendix E and F, respectively. a. Expose people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving:
i. Rupture of a known earthquake fault, as delineated on the most recent AlquistPriolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42.

Summary of Certified SEIR Finding: The Certified SEIR concluded that the City of Ontario is not within any Alquist-Priolo Earthquake Fault Zone. Therefore, impacts would be less than significant, and TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR, pp. 5.7-18 – 5.7-19).

Project Impacts: Ground rupture is the visible offset of the ground surface when an earthquake rupture along a fault affects the Earth’s surface. Southern California, including the City of Ontario, is subject to the effects of seismic activity due to the active faults that traverse the area. Active faults are defined as those that have experienced surface displacement within Holocene time (approximately the last 11,000 years) and/or are in a State-designated AlquistPriolo Earthquake Fault Zone. The Project site is not located with an Alquist-Priolo Earthquake Fault Zone; no known active faults traverse the Project site. The Geotechnical Evaluation concluded that the possibility of damage due to ground rupture is considered low since no active faults are known to cross the site (LGC Geotechnical, 2025). The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Mitigation:

Certified SEIR Measure(s) Project Applicability

ii. Strong seismic ground shaking?
Summary of Certified SEIR Finding: The Certified SEIR concluded that projects considered for approval under TOP 2050 would be required to comply with seismic safety provisions of the CBC (Title 24, Part 2 of the California Code of Regulations). Such compliance would reduce hazards arising from ground shaking to less than significant. Therefore, impacts would be less than significant, and TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR, pp. 5.7-18 – 5.7-19).

Project Impacts: Southern California is a seismically active area and properties in the City of Ontario, including the Project site, are subject to periodic ground shaking and other effects from earthquake activity along nearby regional faults.

The Project site is not at an increased risk relative to the surrounding areas. 816
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Ontario Municipal Code Section 1803.2 requires a geotechnical investigation to evaluate soil classification, slope stability, soil strength, position and adequacy of load-bearing soils, the effect of moisture variation on soil-bearing capacity, compressibility, liquefaction, and expansiveness, as necessary, determined by the City building official. To this end, the Geotechnical Evaluation includes sitespecific recommendations that would be implemented during grading and earthwork operations at the Project site. The geotechnical recommendations would provide adequate protection for the proposed development to the extent required to reduce seismic risk to an “acceptable level,” as defined by the California Code of Regulations.

Additionally, the City requires compliance with the CBC through Title 8, Chapter 1, Section 8-1.01 of the Ontario Municipal Code. The CBC contains provisions for earthquake safety based on factors including occupancy type, the types of soil and rock on-site, and the probable strength of ground motion.

As structures would be designed to meet or exceed CBC standards for earthquake resistance, development of the Project would not create significant impacts related to seismic ground shaking. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Mitigation:

iii. Seismic-related ground failure, including liquefaction? Summary of Certified SEIR Finding: The Certified SEIR concluded that there is currently no potential for liquefaction based on groundwater levels throughout the City being greater than 50 feet below ground surface. Therefore, no impact would occur (Certified SEIR, pp. 5.7-18 – 5.7-19).

Project Impacts: Liquefaction occurs when three general conditions coexist: 1) shallow groundwater, 2) low-density non-cohesive (granular) soils and 3) high817 Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Page 69 of 152 ends

intensity ground motion. Groundwater at the Project site is estimated to be at a depth of approximately 120 to 130 feet below ground surface based on available water well data. As such, the Geotechnical Evaluation concluded that the onsite soils are generally not susceptible to liquefaction due to a lack of groundwater and the relatively dense native soils in the upper 50 feet, and liquefaction potential is considered very low (LGC Geotechnical, 2025).Therefore, consistent with the findings in the Certified SEIR, the Project does not have the potential to expose people or structures to significant seismic-related liquefaction.

The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

iv. Landslides?
Summary of Certified SEIR Finding: The Certified SEIR did not identify any specific constraints regarding landslides (Certified SEIR, pp. 5.7-20 – 5.7-21).

Project Impacts: The Project site and surrounding area are generally flat with no significant slopes. Additionally, the Esperanza Specific Plan DEIR concluded that no significant landslide risk exists within the Specific Plan area. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Page 70 of 152 ends

b. Result in substantial soil erosion or the loss of topsoil? Summary of Certified SEIR Finding: The Certified SEIR concluded that the young alluvial sediment and wind-blown sand underlying the City are generally granular, poorly consolidated, and very susceptible to erosion. However, compliance with the CBC and review of grading plans for individual projects by the City Engineer would ensure no significant impacts would occur. In addition, construction activities on project sites larger than one acre are required to prepare a Stormwater Pollution Prevention Plan (SWPPP) that details best management practices (BMPs) to reduce the potential for erosion during construction activities.

Furthermore, TOP 2050 includes policies addressing erosion and loss of topsoil.

Therefore, impacts would be less than significant, and TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR, pp. 5.7-19 – 5.7-20).

Project Impacts: The State Water Resources Control Board (SWRCB) Order No. 2009-0009-DWQ (General Construction Permit) contains water quality standards and stormwater discharge requirements that apply to construction projects of one acre or more. The General Construction Permit was issued pursuant to the National Pollutant Discharge Elimination System (NPDES) regulations for implementing part of the federal Clean Water Act. The General Construction Permit requires preparation of a SWPPP that identifies the sources of pollution that may affect the quality of stormwater discharges and describes and ensures the implementation of BMPs to reduce the pollutants, including silt and soil, in construction stormwater discharges.

The Project would be required to comply with the NPDES permit by preparing and implementing a SWPPP specifying BMPs for minimizing pollution of stormwater with soil and sediment during Project construction.

Implementation of site-specific BMPs, as well as mandatory compliance with the recommendations set forth in the Geotechnical Evaluation, would reduce, prevent, or minimize soil erosion from Project-related demolition, site preparation and grading, and construction activities. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

c. Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? Summary of Certified SEIR Finding: The Certified SEIR concluded that the thick alluvial deposits comprising the Chino Subbasin may be susceptible to compaction, with resulting subsidence at the surface, in the event of rapid groundwater withdrawal. Projects considered for approval under TOP 2050 could expose structures or persons to potentially significant hazards from ground subsidence. However, compliance with the CBC and review of grading plans for individual projects by the City Engineer would ensure no significant impacts would occur.

Additionally, the young sediments underlying the City are generally dry and loose in the upper few feet, and therefore are susceptible to compression. Much of the Ontario Ranch has been intensively farmed and is especially susceptible to compression. Developments approved pursuant to TOP 2050 could expose persons or structures to potentially significant hazards from compressible soils.

However, compliance with the CBC and review of grading plans for individual projects by the City Engineer would ensure no significant impacts would occur.

Therefore, impacts would be less than significant, and TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR. (Certified SEIR, pp. 5.7-20 – 5.7-21).

Project Impacts: The Project Geotechnical Evaluation provides recommendations that would ensure the Project would not be adversely affected by any unstable soils that may be encountered during the course of Project development. The Evaluation concludes that the Project is feasible from a geotechnical standpoint, provided the recommendations are undertaken (LGC Geotechnical, 2025).

Additionally, the City requires compliance with the CBC through Title 8, Chapter 820

1, Section 8-1.01 of the Ontario Municipal Code. Mandatory compliance with the recommendations of the Geotechnical Evaluation and CBC requirements, as well as review of grading plans by the City Engineer would reduce, prevent, or minimize unstable soil conditions that may be present at the site. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

d. Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial risks to life or property? Summary of Certified SEIR Finding: The Certified SEIR concluded that expansive soils are likely in the southern parts of the City, where there are silts, sandy silts, and silty clays. Projects in the southern part of the City under TOP 2050 could expose persons or structures to potentially significant hazards from expansive soils.

However, compliance with the CBC and review of grading plans for individual projects by the City Engineer would ensure no significant impacts would occur.

Therefore, impacts related to expansive soils would be less than significant and TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR, p. 5.7-21).

Project Impacts: Expansive soils are defined as soils possessing clay particles that react to moisture changes by shrinking or swelling. Based on the results of the expansion index testing presented in the Project Geotechnical Evaluation, on-site soils are anticipated to have a “very low” expansion potential (LGC Geotechnical, 2025). As such, the Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

e. Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater?
Summary of Certified SEIR Finding: Wastewater generated by new development pursuant to buildout of TOP 2050 would be conveyed to and treated at wastewater treatment facilities owned and operated by the Inland Empire Utilities Agency (Regional Plant No. 1 in the City of Ontario and Regional Plant No. 5 in the City of Chino).

The use of septic tanks for new development would be restricted to areas not “in practical proximity existing sewer mains . . .” (Certified SEIR, p. 5.7-22).

Based on the preceding, the Certified SEIR concluded that TOP 2050 would not result in adverse impacts related to use of septic tanks or alternative wastewater disposal systems and ability of soils to accept these systems.

Project Impacts: No septic tanks will be used as part of the proposed Project. The Project would connect to the existing wastewater disposal system. Accordingly, no impact would occur. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

f. Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
Summary of Certified SEIR Finding: The Certified SEIR concluded that the City is underlain by deposits of Quaternary and upper-Pleistocene sediments deposited during Pliocene and early Pleistocene time. Quaternary Older Alluvial sediments may contain significant, nonrenewable, paleontological resources and are therefore considered to have high sensitivity. Older Pleistocene alluvial sediments can yield fossil remains, often found at depths of 10 feet or more below existing ground surface. As a result, the possibility of finding additional paleontological resources within City boundaries is moderate to high at depths of 10 feet or more below ground surface. Therefore, future development that would be accommodated by TOP 2050 could potentially unearth previously unrecorded resources. Mitigation Measure 5-2 requires that in the event of an unanticipated discovery of paleontological resources during grading and excavation of the site, a qualified paleontologist would assess the find and develop a course of action to preserve the find. With application of mitigation, the Certified SEIR concluded that TOP 2050 impacts to paleontological resources would be less than significant (Certified SEIR, pp. 5.7-22 – 5.7-25).

Project Impacts: The Paleontological Assessment identified potentially fossiliferous late Pleistocene alluvial wash or fan deposits at a depth below the Project site.

The occurrence of terrestrial vertebrate fossils at shallow depths from Pleistocene alluvial fan sediments across the Inland Empire is well documented. Due to the high paleontological sensitivity rating typically assigned to Pleistocene alluvial fan sediments, the Paleontological Assessment concluded that paleontological monitoring should be implemented during mass grading and excavation activities in undisturbed Pleistocene alluvial fan sediments, as required by Mitigation Measure 7-1, below.

With the incorporation of Mitigation Measure 7-1, the Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

8. GREENHOUSE GAS EMISSIONS. Would the project:

Information presented within the section is summarized from:
• Esperanza Specific Plan Amendment Greenhouse Gas Assessment (Urban Crossroads, Inc.) March 28, 2025.

The Project-specific Greenhouse Gas Assessment (Urban Crossroads, 2025b) is presented in its entirety as Appendix G to this Addendum. a. Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
b. Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
Summary of Certified SEIR Finding: The Certified SEIR substantiates that TOP 2050 would yield a net decrease in GHG emissions when compared to the previous General Plan (TOP 2009) GHG emissions forecasts. Further, under TOP 2050 and the Community Climate Action Plan (CCAP), the City would achieve State emissions reductions targets and would progress toward attainment of the State’s carbon neutrality goals. On this basis, the Certified SEIR concluded that the potential for TOP 2050 to generate greenhouse gas emissions, either directly or indirectly, that may have an adverse impact on the environment would be less than significant (Certified SEIR, pp. 5.8-25, 5.8-26).

Project Impacts: The Project’s annual GHG emissions are summarized in Table 8- 1, Project GHG Emissions.

As shown in Table 8-1, the Project will result in total GHG emissions of approximately 2,238.00 MTCO2e/yr.

There are currently no published Statewide thresholds of significance for measuring the impact of GHG emissions generated by a proposed project. CEQA Guidelines § 15064.7(b) indicates “each public agency is encouraged to develop and publish thresholds of significance that the agency uses in the determination of the significance of environmental effects.” To this end, the City’s 2022 CCAP contains guidance on the City of Ontario’s GHG Inventory reduction goals, policies, guidelines, and implementation programs.

The CCAP contains Screening Tables which assign points for each option incorporated into a project as mitigation or a project design feature. The point values correspond to the minimum emissions reduction expected from each feature. The menu of features allows flexibility and options for how development projects can implement the GHG reduction measures. Projects that achieve at least 100 points per applicable Screening Table will be consistent with the reduction quantities consistent with the CCAP. Consistent with CEQA Guidelines, such projects would be determined to have a less than significant individual and cumulative impact for GHG emissions.

9. HAZARDS & HAZARDOUS MATERIALS.

Project site information presented in the following discussions is summarized from:
• Phase I Environmental Site Assessment Report, 10.02 Acre Site at Northeast Corner of Amherst and Eucalyptus Avenues, Ontario, California 91761 (SCS Engineers) March 14, 2025.

The Phase I Environmental Site Assessment (ESA) is provided as Addendum Appendix H.
a. Create a significant hazard to the public or the environment through the routine transport, use or disposal of hazardous materials? b. Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment?
Summary of Certified SEIR Finding: The Certified SEIR determined that buildout in accordance with TOP 2050 would involve the transport, use, and/or disposal of hazardous materials. However, federal and State regulations, City ordinances, and TOP 2050 Policies would appropriately control handling of hazardous substances to reduce potential releases; exposure; and risks of transporting, storing, treating, and disposing of hazardous materials and wastes. On this basis, the Certified SEIR concluded that the potential for TOP 2050 to result in adverse impacts related to transport, use, and/or disposal of hazardous materials; creation of significant hazards, or result in hazardous emissions affecting schools, would be less than significant (Certified SEIR, pp. 5.1-4 – 5.1-10). 828

Project Impacts:

Historical Uses of the Project Site
According to the Phase I ESA prepared for the Project site, the site was historically used for agricultural purposes from approximately 1902 through 2012. Around 2016, grading activities were first visible on the eastern portion of the site, associated with activities on the adjoining site to the east. Following 2016, much more extensive grading occurred and in 2020, hundreds of soil stockpiles were placed on the central and northern portions of the site. The appearance of the stockpiles coincided with the grading and paving of the adjoining streets, it is likely that the soil was from sites with similar history (undeveloped and/or agricultural land). Further grading occurred in 2021, which likely resulted in the export or blending of that that stockpiled soil.

Current Conditions
The site is currently a vacant, undeveloped lot. A chain-link fence surrounds the site with gate access in the northeastern corner. The site is covered in low, grassy vegetation and bare soil, with small amounts of wind-blown trash observed on the outer edges of the Property (against the fence).

Regulatory database information did not identify known or suspected contamination sites in the area surrounding the Project site. No evidence of hazardous materials was noted on-site; and the Phase I determined that it was unlikely the site had been affected by activities or releases of hazardous substances from surrounding properties.
829
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Page 81 of 152 ends

The Phase I concluded that no recognized environmental conditions, controlled recognized environmental conditions, or significant data gaps in connection with the site exist, and no further investigation is warranted (SCS, 2025).

Project Construction
During the normal course of construction and operation activities, there would be limited transport of potentially hazardous materials (e.g., gasoline, diesel fuel, paints, solvents, fertilizer, etc.) to and from the Project site. However, as presented within the Certified SEIR, the Project would be required to comply with all City and County Hazardous Materials Management Plans and regulations addressing transport, use, storage and disposal of these materials. The Project does not propose or require uses or activities that would result in atypical transportation, use, storage, or disposal of hazardous or potentially hazardous materials not addressed under current regulations and policies.

Project Operation
The Project would not result in or cause exposure(s) to hazards or potentially hazardous conditions. That is, uses proposed by the Project are not considered hazardous. Nor does the Project propose or require facilities or operations involving inherent substantial hazards.

Consistent with the findings of the Certified SEIR, with mandatory compliance City and County Hazardous Materials regulations, potential hazardous materials impacts associated with the Project is not expected to pose a significant hazard to the public or environment through the routine transport, use, or disposal of hazardous materials, nor would the Project increase the potential for accident operations which could result in the release of hazardous materials into the environment. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

c. Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances or waste within one-quarter mile of an existing or proposed school?
Summary of Certified SEIR Finding: The Certified SEIR determined that buildout in accordance with TOP 2050 would involve the transport, use, and/or disposal of hazardous materials. However, federal and state regulations, City ordinances, and TOP 2050 Policies would appropriately control handling of hazardous substances to reduce potential releases; exposure; and risks of transporting, storing, treating, and disposing of hazardous materials and wastes. On this basis, the Certified SEIR concluded that the potential for TOP 2050 to result in adverse impacts related to transport, use, and/or disposal of hazardous materials; creation of significant hazards, or result in hazardous emissions affecting schools, would be less-than-significant (Certified SEIR, pp. 5.1-4 – 5.1-10).

Project Impacts: The Project site is not located within one quarter mile of an existing or proposed school. The closest school to the Project site is Colony High School, located approximately 1.5 miles to the north. The Project does not propose or require uses that would handle hazardous or acutely hazardous materials, substances, or waste. Implementation of the Project would not have the potential to emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one quarter mile of an existing or proposed school. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

d. Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? Summary of Certified SEIR Finding: Development in accordance with TOP 2050 would involve redevelopment and reuse of some sites listed as hazardous materials sites on environmental databases. The environmental databases document the presence of hazardous materials on those sites, but do not document hazardous releases. Redevelopment of the affected sites could potentially expose future residents and workers to hazards from known hazardous materials releases on and near the sites. Should environmental database listed sites be proposed for development, site assessments for hazardous materials and remediation of hazardous materials releases would be required in accordance with TOP 2050 Policies, federal, state, and local regulations. On this basis, the Certified SEIR concluded that the potential for development pursuant to TOP 2050 to be located on hazardous materials sites, and thereby create adverse hazard impacts affecting the public or environment would be less than significant (Certified SEIR, pp. 5.9-38, 5.9-39).

Project Impacts: A records review conducted as part of the Phase I Environmental Site Assessment did not identify the site as a hazardous material site pursuant to Government Code Section 65962.5. Additionally, no adjacent sites were identified as potentially affecting the Project site (SCS, 2025). Therefore, the Project would not create a hazard to the public or the environment and no impact is anticipated. When compared to the Certified SEIR findings, no new or substantially increased impacts related to development affecting Government Code Section 65962.5-listed sites would result from the Project.

e. For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area?
Summary of Certified SEIR Finding: Ontario International Airport (ONT), as well as a small portion of the Chino Airport property, is located within the City of Ontario.

The Certified SEIR determined that TOP 2050 Policies and established processes for consistency reviews of new development with the appropriate Airport Land Use Compatibility Plan (ALUCP) would be sufficient to prevent significant impacts (Certified SEIR, p. 5.8-27).

Project Impacts: The Project site is located approximately four miles south of the Ontario International Airport (ONT). The ONT Airport Land Use Compatibility Plan (ALUCP) was adopted by Ontario City Council on April 19, 2011 (amended 2018) to promote compatibility between the airport and the land uses that surround it.

The Project site is located within the area subject to provisions of The ONT ALUCP, which defines the ONT Airport Influence Area (AIA) as an area in which current and future airport-related noise, overflight, safety, and airspace protection factors may significantly affect land uses or necessitate restriction on those uses.

The Project site is located outside the ONT safety zones (see: TOP 2050 Policy Plan Figure LU-06, Airport Safety Zones & Influence Areas). As with the development anticipated under TOP 2050, and evaluated in the Certified SEIR, the Project would comply with all requirements set forth within the ALUCP. Based on the preceding, the potential for the Project to result in airport-related safety hazard impacts would be less than significant.

The Project site is located approximately 2.5 miles east of the Chino Airport (CNO).

The Project site is located outside the CNO airport influence area and airport safety zones. At this distance, airport hazards from CNO would be less than significant.

The Project would not result in a safety hazard for people residing or working in the Project area. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

f. Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
Summary of Certified SEIR Finding: In 2018, the City of Ontario prepared a Local Hazard Mitigation Plan (LHMP) to identify the City’s hazards, review and assess past disaster occurrences, estimate the probability of future occurrences, and set goals to reduce or eliminate long-term risk to people and property from natural and man-made hazards. Wildfire hazard is rated the highest risk of the 23 hazards evaluated, followed by flooding. Under the LHMP, interstate highways would serve as major emergency response and evacuation routes. TOP 2050 Policies and local roadways are designed and constructed so as to facilitate access under normal and emergency conditions.

A review of emergency access is included as part of the standard City’s Design Review process. Additionally, the Ontario Fire Department reviews development applications to ensure that adequate emergency accessibility is provided based on local and state guidance.

Based on the preceding, the Certified SEIR concluded that buildout of the City in accordance with TOP 2050 would not impair implementation of, or physically interfere with, an adopted emergency response plan or emergency evacuation plan. Impacts in these regards would be less than significant (Certified SEIR, p. 5.9- 41).

Project Impacts: The Project does not propose or require permanent alteration of vehicle circulation routes, and would not interfere with any identified emergency response or emergency evacuation plan. Standard City design review processes include coordination with fire and police departments during pre-construction review of plans to ensure that potential interference with emergency response plans and evacuation plans are avoided. Based on the preceding, the Project 834

g. Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires?
Summary of Certified SEIR Finding: The Certified SEIR identifies available resources addressing wildland fires and associated potential impacts. These resources include: CAL FIRE 2019 Strategic Fire Plan for California, the California Fire Code, County of San Bernardino Multi-jurisdiction Hazard Management Plan, the Ontario LHMP, and fire services from the Ontario Fire Department. The Certified SEIR determined that adherence to existing regulations and review of building plans by the Ontario Fire Department, development and infrastructure associated with TOP 2050 would not exacerbate risk or result in post-wildfire hazards. No significant impacts were identified (Certified SEIR, p. 5.9-41).

Project Impacts: The Project site is located in an urbanized area, and no wildlands are located in the vicinity of the site. Fire protection services are provided by the Ontario Fire Department. Pre-construction coordination with Ontario Fire Department staff and adherence to local fire department regulations during construction and operation of the Project would be required. As such, no new or substantially increased impacts related to wildland fire impacts would result from the Project. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

10.HYDROLOGY & WATER QUALITY. Would the project:

Project-specific information presented in the following discussions is primarily based on information contained within the following documents:
• Drainage Study for Tract No. 20730 Esperanza – PA 11, Eucalyptus Avenue & Amherst Avenue, Ontario, CA (Walden & Associates) March 2025. • Preliminary Water Quality Management Plan (PWQMP), March 12, 2025.

These reports are presented as Appendices I1 and I2 to this Addendum. a. Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? Summary of Certified SEIR Finding: The Certified SEIR recognizes that buildout of the City pursuant to TOP 2050 would increase concentrations of pollutants during construction and post-construction activities. To address potential water quality impacts resulting from project construction and operations, projects are required to comply with provisions of the City’s National Pollutant Discharge Elimination System (NPDES) permit. NPDES permit requirements include, but are not limited to, mandated preparation of a Stormwater Pollution Prevention Plan (SWPPP) and Water Quality Management Plan (WQMP). Mandated SWPPPs and WQMPs are required to develop and implement Best Management Practices (BMPs) to reduce construction-source and operational-source stormwater pollutant discharges. Based on compliance with the City NPDES Permit and implementation of required SWPPPs and WQMPs, the Certified SEIR did not identify any significant water quality impacts (Certified SEIR, p. 5.10-21). 836

Page 88 of 152 ends

Project Impacts: Consistent with City requirements, a Preliminary WQMP has been prepared for the Project. The WQMP identifies the Source Control and Treatment Control BMPs to be implemented by the Project, including:

Source Control BMPs
• Minimize non-stormwater site runoff through efficient irrigation system design and controllers.
• Minimize trash and debris in storm runoff through a regular parking lot, storage yard and roadway sweeping program.
• Provide solid roofs over all trash enclosures.
• Site Owner(s)/Property Manager/HOA or POA will be familiar with the Project WQMP and stormwater BMPs.
• Owner or HOA or POA to provide education/training of site occupants and employees on stormwater BMPs.
• Install stormwater placards/stenciled messages with a “No Dumping” message on all on-site/off-site storm drain inlets.

Treatment Control BMPs
• Proprietary Filter Inserts for on-site storm drain inlets or retention basin/trench overflow drains
City review and approval of the WQMP and SWPPP documents is required prior to issuance of grading permits. As determined by the Certified SEIR, implementation of an approved SWPPP and WQMP would reduce the potential for the development under the Project to violate water quality standards or otherwise adversely affect water quality to levels that would be less than significant.

Based on the preceding, the Project’s potential to violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality is considered less than significant. When compared to the Certified SEIR findings, no new or substantially increased water quality impacts would result from the Project.

b. Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin?
Summary of Certified SEIR Finding: As discussed in the Certified SEIR, “[a]pproximately 46 percent of the City’s water supply is groundwater pumped by the City from the Chino Groundwater Basin; groundwater pumping is managed by OMUC so that domestic demands do not exceed the safe yield for the basin, consistent with the Chino Basin Watermaster’s Optimum Basin Management Program, commonly called the ‘OBMP Peace Agreement’” (Certified SEIR, p. 5.10-22). The Certified SEIR notes further “the Chino Groundwater Basin is adjudicated and is considered by DWR to be a very low priority groundwater basin. Each water purveyor has an allotted amount of water that can be pumped from the basin so that the safe yield is not exceeded. The City has access to additional water supplies that can accommodate the proposed increase in growth with buildout of [TOP 2050] and would not interfere with sustainable management of the groundwater basin” (Certified SEIR, p. 5.10-22).

The Certified SEIR recognizes that development pursuant to TOP 2050 would increase the amount of impervious surface within the City. However, groundwater recharge efforts would not be hindered. To these ends, all development projects within the City would be required to prepare project-specific hydrology studies, implement low impact development BMPs and comply with NPDES regulations supporting TOP 2050 Policies promoting infiltration of runoff and groundwater recharge.

Based on the preceding, TOP 2050 would not result in substantial adverse impacts affecting groundwater supplies, groundwater recharge, or groundwater sustainability (Certified SEIR, p. 5.10-23).

Project Impacts: Direct additions to or withdrawals of groundwater are not proposed or required by the Project. Construction proposed by the Project would not involve massive substructures at depths that would significantly impair or alter the direction or rate of flow of groundwater. The Project does not propose or require uses or facilities that would affect designated groundwater recharge areas. The Project has prepared a Drainage Study and Preliminary WQMP, and would comply with NPDES regulations supporting TOP 2050 Policies promoting groundwater recharge.

Based on the preceding, the Project would not result in substantial adverse impacts affecting groundwater supplies, groundwater recharge, or groundwater sustainability. When compared to the Certified SEIR findings, no new or substantially increased water quality impacts would result from the Project.

c. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would? i. Result in substantial erosion or siltation on- or off-site; Summary of Certified SEIR Finding: Consistent with NPDES requirements, runoff quantities would not be permitted to substantially increase as a result of a development under TOP 2050. In this regard, projects would be required to prepare project-specific hydrology studies. Further, existing City policies encourage the use of low impact development strategies to intercept runoff, reduce stormwater discharge rates, increase infiltration and ultimately reduce discharge volumes to traditional storm drain systems.

The Certified SEIR notes that while the amount of impervious surfaces would be increased under TOP 2050 (and thus surface water flows into drainage systems), 839
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Page 91 of 152 ends

compliance with existing City and County requirements would ensure significant impacts related to alteration of drainage patterns do not occur. Additionally, City policies and regulations act to minimize or avoid development or other actions that would potentially result in impedance or redirection of flood flows (Certified SEIR, pp. 5.10-23 – 5.10-27).

Project Impacts: The Project site currently drains in a southwesterly direction towards the intersection of Eucalyptus Avenue and Amherst Avenue where an onsite detention basin is located. The basin has a 36-inch inlet that joins a public storm drain in Amherst Avenue. The Project would implement an on-site storm drain system that generally maintains the existing drainage pattern and connects to the existing storm drain in Amherst Avenue.

Additionally, compliance with construction-related BMPs and the SWPPP would control and minimize erosion and siltation, resulting in a less than significant impact. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

ii. Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on or off-site;
Summary of Certified SEIR Finding: The Certified SEIR concluded that future development would increase the amount of impermeable surfaces in the City, which could result in future on- and off-site flooding. The City’s standard conditions of approval for new development also require the preparation of hydrology studies and drainage analyses that document the peak runoff rates from the developed site and evaluate the capacity of the storm drain system to accept these flow rates. Additionally, TOP 2050 policies would direct the City to incorporate strategies to capture, slow, or treat run-off and to reduce the flooding 840
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

potential down-gradient of new development. These policies would reduce the potential for on- and off-site flooding during the operational phase of future development projects. Therefore, impacts would be less than significant and TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR pp. 5.10-23 – 5.10-26).

Project Impacts: Based on the capacity of the surrounding storm drain system, the maximum permitted outflow from the developed site is 15.64 cubic feet per second (cfs). The Project-specific Drainage Study documents the postdevelopment peak runoff rates and verifies that the Projects on-site storm drainage system would function as a flow restriction by oversizing the on-site system capacity and providing on-site storage. Outflow would be released from the site at no more than 15.64 cfs at any time. As such, runoff from the Project site would not have an adverse effect to the existing storm drain system downstream.

The Project would not substantially increase the rate or amount of surface runoff in a manner which would result in flooding on or off-site. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

iii. Create or contribute runoff water which would exceed the capacity or existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff;
Summary of Certified SEIR Finding: The Certified SEIR concluded that projects considered for approval under TOP 2050 would be required to prepare projectspecific hydrology and hydraulic studies as required by the City. In compliance with the MS4 Permit and San Bernardino County Stormwater Program, new development projects would also be mandated to install stormwater treatment BMPs that retain the 2-year, 24-hour rainfall event. Because new development in the City would be required to prepare a hydrology study and drainage analysis 841
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Page 93 of 152 ends

in accordance with the San Bernardino County Hydrology Manual, no significant impacts would occur. Therefore, TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR pp. 5.10-23 – 5.10-26).

Project Impacts: As stated above, the proposed on-site storm drainage system would function as a flow restriction by oversizing the on-site system capacity and providing on-site storage. Outflow would be released from the site consistent with the capacity of the surrounding storm drain system.

Accordingly, the Project would not create or contribute runoff that would exceed the capacity of any existing stormwater drainage system. Consistent with the finding of the Certified SEIR, stormwater generated by the Project will be discharged in compliance with the Statewide NPDES General Construction Activities Stormwater Permit and San Bernardino County MS4 permit requirements.

The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

iv. Impede or redirect flood flows?
Summary of Certified SEIR Finding: The Certified SEIR concluded that only small portions of the City adjacent to flood control channels, detention basins, and creeks are in the 100-year floodplain. The western portion of Ontario Ranch is labeled Zone D, undetermined flood hazard, and no hazard analysis has been completed for this area. TOP 2050 includes policies to reduce impacts of potential development within 100-year flood zones. Additionally, Chapter 13 of the Ontario Municipal Code requires that a development permit be obtained prior to development in a special flood hazard area to ensure that the site is reasonably safe from flooding and flood hazards. With implementation of existing policies, the 842

potential for the project to impede or redirect flood flows is considered less than significant. Therefore, TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR pp. 5.10-23 – 5.10-26).

Project Impacts: According to the Federal Emergency Management Agency (FEMA) flood map No. 06071C9375J, the Project site is located within Zone X, an area of minimal flood hazard (FEMA, 2024). Additionally, as shown in Figure 5.10- 2 of the Certified SEIR, the Project site is not located within an identified flood hazard zone. Therefore, the Project would not impede or redirect flood flows and no impact would occur. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

d. In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation?
Summary of Certified SEIR Finding: As discussed in the Certified SEIR, “there are no large bodies of water that would result in a seiche during seismic activity.

Additionally, the reservoirs/aboveground water tanks within the City are enclosed, thereby minimizing the possibility of a seiche. The [City] is inland and approximately 30 miles from the ocean and is not at risk of flooding due to tsunamis.

The western and southern portions of the City are in the dam inundation zone of San Antonio Dam. The probability of dam failure is very low, and Ontario has never been impacted by a major dam failure. In addition, dam owners are required to maintain emergency action plans that include procedures for damage assessment and emergency warnings. Because the likelihood of catastrophic failure of the San Antonio Dam is very low and the City has emergency action 843
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

plan (EAP) notification procedures, impacts of release of pollutants due to dam inundation are considered less than significant.

Based on the preceding, the Certified SEIR concluded that TOP 2050 would not result in adverse impacts related to flood hazard, tsunami, or seiche zones, risk release of pollutants due to inundation (Certified SEIR, pp. 5.10-26, 5.10-27).

Project Impacts: Conditions at the Project site with regard flood hazard impacts, tsunami hazard impacts, or seiche hazard impacts have not changed since preparation of the Certified SEIR – the site remains unaffected by substantial potential flood hazards, tsunami hazards, or seiche hazards. The potential for the Project to result in release of pollutants due to an inundation event would be less than significant. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

e. Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan?
Summary of Certified SEIR Finding: As discussed in the Certified SEIR, “[p]rojects approved under TOP 2050 would be required to comply with the Santa Ana River Basin Plan and to control pollutants in discharges of stormwater from postconstruction activities under NPDES Permit No. CAS618036 through preparation of a WQMP identifying BMPs for prevention of stormwater pollution during the postconstruction phase, including site-design, source-control, and/or treatment BMPs.

Therefore, [TOP 2050] would not obstruct or conflict with the RWQCB’s Basin Plan or any groundwater management plan, and impacts would be less than significant” (Certified SEIR, p. 5.10-27).

Project Impacts: Project-related construction and operational activities would be required to comply with the Santa Ana RWQCB’s Santa Ana River Basin Water Quality Control Plan by preparing and adhering to an SWPPP and WQMP.

The Project site is located within the Chino Groundwater Basin. Upon development, the Project site will be connected to the City’s public water supply and there will be no on-site wells for use of groundwater. The City manages both the potable and non-potable supplies to ensure withdrawals from the Chino Groundwater Basin do not exceed the safe yield for the Basin, as per the Chino Basin Watermaster's Optimum Basin Management Program (OBMP). Therefore, the Project would not obstruct or conflict with the OBMP. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

11. LAND USE & PLANNING. Would the project:
a. Physically divide an established community?
Summary of Certified SEIR Finding: The Certified SEIR concluded that the changes in land use that would occur upon the implementation of TOP 2050 Land Use Plan would not result in the physical division of an established community. The Land Use Element of TOP 2050 contains policies and programs that encourage the preservation or enhancement of the existing, primarily residential community through infill development, open space opportunities, and development of compatible uses that would reduce the amount of conflict between contradicting land uses and enhance the existing character of Ontario. TOP 2050 would avoid conflicting land uses and would not divide an established community (Certified SEIR, p. 5.11-6).

Page 97 of 152 ends

Project Impacts: The Project site is currently vacant; No established community is located within the site. The Esperanza Specific Plan assumed the site would be developed with residential uses, should the Mountain View School District choose not to acquire the site. The site is surrounded by existing/proposed residential development, and the Project represents the logical continuation of such uses.

The Project would not otherwise result in potential division of an established community. The Project would have no impacts in this regard.

b. Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?
Summary of Certified SEIR Finding: The Certified SEIR concluded that implementation of TOP 2050 would not result in significant land use impacts (Certified SEIR, p. 5.11-11).

Project Impacts: The Project site is designated for School use by the TOP 2050 and the Esperanza Specific Plan. To accommodate the proposed uses, the Project would require a General Plan Amendment and Specific Plan Amendment to redesignate the site as Medium Density Residential (MDR). The Project would be implemented consistent with all Design Guidelines and Development Regulations presented in the Esperanza Specific Plan for MDR uses. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

12.MINERAL RESOURCES. Would the project:
a. Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state?
b. Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan?
Summary of Certified SEIR Finding: The Certified SEIR concluded that implementation of TOP 2050 would have a less than significant potential to result in the loss of a known mineral resource of value to the region or the state; or result in the loss of availability of a locally-important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan (Certified SEIR, p. 5.12-6).

Project Impacts: Underlying conditions at the subject site have not changed since preparation of the Certified SEIR or the Esperanza Specific Plan DEIR. The Project site is located within a mostly developed area surrounded by urban land uses. As shown in Figure 5.12-1 of the Ontario Plan 2050 Draft SEIR, the Project site is designated as MRZ-3. The Certified SEIR states, “[d]evelopment in an MRZ-3 area would not result in significant impacts because mineral resources of statewide or local importance are not identified on the California Geological Survey’s P-C maps.” Additionally, the Esperanza Specific Plan DEIR concluded that buildout of the Specific Plan area would not result in significant impacts to mineral resources.

The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

a. Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?
Summary of Certified SEIR Finding: The Certified SEIR determined that new development implemented pursuant to TOP 2050 would result in temporary noise increases at sensitive receptors during construction activities (Certified SEIR, p.

5.13-28). Certified SEIR Mitigation Measure 12-4, below, would reduce construction noise but would not avoid this impact or reduce the impact to levels that would be less than significant. No other significant impacts in this regard were identified.

Construction-Source Noise Impacts
In the evaluation of construction-source noise impacts, the Noise Impact Analysis employs empirical reference noise measurements obtained from similar construction activities. Based on the reference construction noise levels, maximum received noise levels attributable to the Project construction activities were calculated and are summarized at Table 13-2. Compliance with applicable significance thresholds is also presented.

Operational-Source Noise Impacts
The Project is considered a noise-sensitive receiving land use and is not expected to include any specific type of operational noise levels beyond those typically associated with residential land uses in the Project study area. Additionally, Section 21085 of the California Public Resources Code states in part, “…for residential projects, the effects of noise generated by project occupants and their guests on human beings is not a significant effect on the environment.” A review of the legislative record indicates the author’s intent for Section 21085 was to “remove the potential for litigants to challenge residential development based on the speculation that the new residents will create unwanted noises. It would also reestablish existing precedent that minor and intermittent noise nuisances, such as from unamplified human voices, be addressed through local nuisance ordinances and not via CEQA. Consequently, activities solely associated with occupants and quests, such as the swimming pool/spa activities, dog park activities, and outdoor activities in common spaces, are not considered part of this operational noise analysis for CEQA.”
Based on the intent of the author of Section 21085, the operational noise sources are limited to the mechanical and non-verbal noise sources that occur on-site, including air conditioning units, trash enclosure activity, and parking lot movements. The Noise Impact Analysis employs empirical reference noise measurements obtained from similar operational activities. Based on the reference noise levels, maximum received noise levels attributable to the Project operational activities were calculated and are summarized at Table 13-3.

Compliance with applicable significance thresholds is also presented. 851

As shown above, the operational noise levels associated with the Project will satisfy the City of Ontario 65 dBA Leq daytime and 45 dBA Leq nighttime exterior noise level standards at all the nearest receiver locations. Therefore, the operational noise impacts are considered less than significant at the nearest noise-sensitive receiver locations.

To describe the Project operational noise level increases, the Project operational noise levels are combined with the existing ambient noise level measurements for the nearest receiver locations potentially impacted by Project operational noise sources. Noise levels that would be experienced at receiver locations when Project-source noise is added to the daytime and nighttime ambient conditions are presented in Tables 13-4 and 13-5, respectively.

Vehicular-Source Noise Impacts
Off-Site Traffic Noise
Based on the Project trip generation analysis, the Project’s traffic volumes would not result in an increase on vicinity roadways greater than those assumed under TOP 2050 or analyzed within the Esperanza Specific Plan DEIR. As such, off-site traffic noise impacts would be less than significant.

On-Site Traffic Noise
An on-site noise impact analysis has been completed to determine the noise exposure levels resulting from adjacent transportation noise sources in the Project study area and identify potential noise attenuation measures that would achieve acceptable Project exterior and interior noise levels.

The on-site exterior traffic noise analysis indicates that all buildings would experience exterior noise levels ranging from 59.3 to 64.4 CNEL. Based on the City of Ontario Land Use Compatibility for Community Noise Exposure (Noise Impact Analysis Exhibit 3-A), the Project land uses would be considered clearly acceptable to normally acceptable with exterior noise levels of less than 65 dBA CNEL.

To ensure that the interior noise levels comply with the interior noise level standards, future exterior noise levels were calculated at the first, second, and 853

third floor building façade/balcony locations. The interior noise level is the difference between the predicted exterior noise level at the building facade and the noise reduction of the structure. Typical building construction will provide a noise reduction of approximately 12 dBA with "windows open" and a minimum 25 dBA noise reduction with "windows closed." With standard construction, the following interior noise levels are expected:
• First Floor: 33.9 to 39.4 dBA CNEL
• Second Floor: 38.5 to 40.5 dBA CNEL
• Third Floor: 35.4 to 40.3 dBA CNEL
Based on the preceding, on-site interior traffic noise levels will not exceed the City of Ontario 45 dBA CNEL interior noise level standard for residential development.

Summary
As demonstrated in the preceding analysis, Project construction-source, operational-source, and/or vehicular-source noise would not result in the generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the Project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies.

b. Generation of excessive groundborne vibration or groundborne noise levels?
Summary of Certified SEIR Finding: The Certified SEIR determined that mobilesource and stationary/area-source vibration impacts associated with buildout of TOP 2050 would be less-than-significant. However, construction activities associated with buildout of the individual land uses could expose sensitive uses to strong levels of groundborne vibration. The Certified SEIR concluded even with the implementation of Mitigation Measure 12-2, construction-source groundborne vibration impacts would be significant and unavoidable (Certified SEIR, pp. 5.13-38 – 5.13-41).

Project Impacts: Using reference vibration levels and methods defined by the FTA, Table 13-6 presents the expected Project-related vibration levels at the nearby receiver locations.

Source: Urban Crossroads, 2025c
As shown above, at distances ranging from 75 to 202 feet from Project construction activities, construction vibration velocity levels are estimated to range from less than 0.01 to 0.02 in/sec PPV. Based on the Caltrans maximum acceptable continuous vibration threshold of 0.30 PPV (in/sec), the typical Project construction vibration levels will fall below applicable thresholds at all the receiver locations. Moreover, the vibration levels at the sensitive receiver locations are unlikely to be sustained during the entire construction period but will occur rather only during the times that heavy construction equipment is operating adjacent to the Project site perimeter.

Based on the preceding, the Project would not result in any new or increased groundborne vibration or groundborne noise impacts than those previously considered and addressed in the Certified SEIR.

c. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? Summary of Certified SEIR Finding: The Certified SEIR concluded that Chino Airport does not significantly affect sensitive receptors within the City of Ontario.

However, sensitive land uses within the 65 dBA CNEL noise contour of the Ontario International Airport would be exposed to substantial levels of airport-related 859
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

noise. Even with the implementation of Mitigation Measure 12-1, airport-related noise was deemed a significant and unavoidable impact of TOP 2050 (Certified SEIR, pp. 5.13-38 – 5.13-41).

Project Impacts: The Project site is located approximately four miles south of the Ontario International Airport (ONT). The Ontario International Airport Land Use Compatibility Plan was adopted by Ontario City Council on April 19, 2011 (amended 2018) to promote compatibility between the airport and the land uses that surround it. The Project site is located within the ONT airport influence area, but is not located within a designated noise impact zone. The Project would therefore not be exposed to excessive airport/airfield-source noise levels associated with ONT operations.

The Project site is located approximately 2.5 miles east of the Chino Airport (CNO).

The Project site is not located within a designated CNO noise impact zone. At this distance, airport noise level impacts would be less than significant.

The Project would not otherwise be exposed to potentially adverse airport/airfield-source noise levels, nor does the Project propose or require uses that would contribute to or exacerbate airport-source noise impacts. Based on the preceding, the Project would not be adversely affected by airport/airfield noise, nor would the Project contribute to or result in adverse airport/airfield noise impacts. When compared to the Certified SEIR findings, no new or substantially increased airport/airfield noise impacts would result from the Project.

14.POPULATION & HOUSING. Would the project:
a. Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of road or other infrastructure)? Summary of Certified SEIR Finding: The Certified SEIR concluded that implementation of TOP 2050 accommodates population growth through land use designations, goals, and policies that provide a vision and guide growth in the City. TOP 2050 would increase population, dwelling units, and nonresidential buildings but would result in a small decrease in employment. Although the increase in population, housing, and employment under TOP 2050 would exceed SCAG’s regional forecasts for the City of Ontario, TOP 2050 would improve the job-housing balance. Consequently, impacts would be less than significant, and TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR, pp. 5.14-9 – 5.14-12).

Project Impacts: The Project would result in the development of 161 residential units. The Esperanza Specific Plan noted that 46 residential units could be developed within the Project site, should the school not be developed. This means that the Project would result in 115 residential units not originally anticipated by the Specific Plan.

According to the SCAG’s Connect SoCal 2024, housing production within the region has historically lagged behind the growing population. While housing unit production has increased since 2000, the region still has a backlog of unmet 861
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

housing needs from previous decades. (SCAG, 2024) As further detailed in the Certified SEIR, the City of Ontario has an imbalanced jobs-housing ratio of 2.3 (ideal range is 1.3 to 1.7). The population in Ontario is expected to increase from 172,200 in 2020 to 269,100 persons, a difference of 96,900 persons (a 56.3 percent increase) between 2016 and 2045. The number of housing units in the City are forecast to increase from 48,269 to 78,174, a difference of 29,906 (a 62 percent increase) between 2016 and 2045.

The addition of the 161 residential units proposed by the Project in a jobs-rich region such as Ontario would not induce substantial unplanned population growth in the area. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Mitigation:

Certified SEIR Measure(s) Project Applicability

b. Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?
Summary of Certified SEIR Finding: The Certified SEIR concluded that land use changes under TOP 2050 would increase opportunities for housing in the City. The TOP 2050 Land Use Plan would provide land use designations for a variety of housing types and provide for additional residential opportunities throughout Ontario. TOP 2050 includes policies supporting an increase in the provision of housing and diversity of housing opportunities in the City. Therefore, impacts would be less than significant and would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR, pp. 5.14- 9 – 5.14-12).

Project Impacts: The Project site does not contain any housing and there are no people living at the Project site that would be displaced by the Project. Therefore, no impacts are anticipated. The Project would not result in any new, increased or 862

15.PUBLIC SERVICES. Would the project:
a. Result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services:
i. Fire protection?
Summary of Certified SEIR Finding The Certified SEIR concluded that existing Ontario Fire Department facilities would not be adequate to meet increased demands from the implementation of TOP 2050. While the construction of future facilities could result in potential environmental impacts, future environmental review would occur once specific locations have been determined. Without a definitive location for the development of future facilities, the analysis of potential impacts is too speculative to conduct. Future projects would be reviewed by the City and the Ontario Fire Department on an individual basis and would be required to comply with requirements in effect at the time building permits are issued, including the payment of Development Impact Fees that contribute to funding for additional staffing, facilities, and equipment. Therefore, impacts to fire protection services would be less than significant (Certified SEIR, pp. 5.15-3 5.15- 5).

Project Impacts: The Project does not propose or require construction or modification of fire protection facilities. The Project site is not designated or 863
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

proposed as the location for new or modified fire protection facilities. Incremental fire protection service demands generated by the Project are offset through the payment of Development Impact Fees. A portion of the City’s Development Impact Fees are allocated for fire protection services. The Project Applicant would pay incumbent City Development Impact Fees at issuance of building permit(s).

To the satisfaction of the Ontario Fire Department, the Project would comply with City and Fire Department fire prevention and suppression requirements, including building/site design requirements, fire flow adequacy, and provisions for emergency access, thereby reducing potential increased demands for fire protection services.

Based on the preceding, the potential for the Project to result in substantial adverse physical impacts associated with the provision of the new or physically altered fire protection facilities is considered less than significant. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Mitigation:

Certified SEIR Measure(s) Project Applicability

ii. Police protection?
Summary of Certified SEIR Finding: The Certified SEIR concluded that the Ontario Police Department has enough staffing to meet current demands, but would require additional staffing as population increases to accommodate buildout of TOP 2050. While the construction of future facilities could result in potential environmental impacts, future environmental review would occur once specific locations have been determined. Without a definitive location for the development of future facilities, the analysis of potential impacts is too speculative to conduct. Future development would also be subject to development impact fees which pay for police services. Therefore, impacts to police protection services would be less than significant (Certified SEIR pp. 5.15-6 – 5.15-7).
864
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Page 116 of 152 ends

Project Impacts: The Project does not propose or require construction or modification of police protection facilities. The Project site is not designated or proposed as the location for new or modified police protection facilities.

Incremental police protection service demands generated by the Project are offset through the payment of Development Impact Fees. A portion of the City’s Development Impact Fees are allocated for police protection services. The Project Applicant would pay incumbent City Development Impact Fees at issuance of building permit(s).

Additionally, the Project site plan concept and proposed building designs would be reviewed by the Ontario Police Department to ensure incorporation of appropriate safety and security elements. Such design features would include secure building designs, defensible spaces, and area and facility security lighting.

These design features would act to reduce Project demands for police protection services.

Based on the preceding, the potential for the Project to result in substantial adverse physical impacts associated with the provision of the new or physically altered police protection facilities is considered less than significant. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Mitigation:

iii. Schools?
Summary of Certified SEIR Finding: The Certified SEIR concluded that although the increased demand on school facilities would have the potential to impact one or more of the school districts that serve Ontario, payment of impact fees in compliance with SB 50 would reduce the impacts to an acceptable level.

Therefore, impacts to school services would be less than significant and implementation of TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR, p. 5.15-14) 865
Addendum to The Ontario Plan 2050 Supplemental Environmental Impact Report File No(s).: PPA24-0139, PGPA24-004, PSPA24-004, PDEV24-017, PMTT24-008, PDA25-003

Page 117 of 152 ends

Project Impacts: The Project would develop 161 residential units that could result in populations of resident school-aged children. As determined by the Certified SEIR, Project incremental impacts to school services would be offset through payment of school impact fees. The Project Applicant would pay incumbent school impact fees at issuance of building permit(s). Payment of school impact fees would reduce the Project’s potential impacts to school services to levels that would be less than significant.

The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

iv. Parks?
Summary of Certified SEIR Finding: Park service was discussed under the Recreation section of the Certified SEIR. The Certified SEIR concluded that impacts to recreation would be less than significant, and implementation of TOP 2050 would not result in new or a substantial increase in magnitude of impacts compared to the Certified SEIR (Certified SEIR, pp. 5.16-12 – 5.16-14). Details of the summary findings are discussed below in Section 16, Recreation.

Project Impacts: As discussed in Section 16, Recreation, the Project proposes residential uses that could increase the use of neighborhood and regional parks or other recreational facilities. As presented within the Certified SEIR, the Project would be required to provide sufficient public parkland or pay in-lieu fees.

Additionally, the development would provide on-site recreational amenities to serve future residents, including a pool/spa, playground, shaded barbeque/picnic area, fitness stations, and open turf areas. As such, the Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR. 866

v. Other public facilities?
Summary of Certified SEIR Finding: The Certified SEIR concluded that implementation of TOP 2050 would not result in potentially significant other public services impacts (Certified SEIR, pp. 5.15-17 – 5.15-18) Project Impacts: Development of the Project would require established public agency oversight including, but not limited to, various plan check and permitting actions by the City. Impacts of the Project would fall within routine tasks of these agencies/departments and are paid for via plan check and inspection fees.

Impacts of the Project would not be of such magnitude that new or physically altered facilities would be required. There are no known or probable other public facilities that would be substantially affected by the Project. Based on the preceding, the potential for the Project to result in substantial adverse physical impacts associated with the provision of the new or physically altered other public facilities is considered less than significant. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Page 119 of 152 ends

Summary of Certified SEIR Finding: The Certified SEIR concluded that future growth in the City in accordance with buildout of TOP 2050 would increase the demand for parks and increase existing park usage. The Certified SEIR determined that because new development would be required to provide sufficient public parkland or pay in-lieu fees, impacts to recreational facilities would be less than significant (Certified SEIR, pp. 5.16-12 – 5.16-14).

Project Impacts: The Project proposes residential uses that could increase the use of neighborhood and regional parks or other recreational facilities. As presented within the Certified SEIR, the Project would be required to provide sufficient public parkland or pay in-lieu fees. Additionally, the development would provide on-site recreational amenities to serve future residents, including a pool/spa, playground, shaded barbeque/picnic area, fitness stations, and open turf areas. In total, these active common open space amenities would encompass 60,950 sf (1.40 acre).

As such, the Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

c. Does the project include recreational facilities or require the construction or expansion of recreational facilities that have an adverse physical effect on the environment?
Summary of Certified SEIR Finding: The Certified SEIR concluded that TOP 2050 includes planned park facilities; however, it is speculative to determine the location of proposed park facilities in the City and impacts arising from development of individual park projects. Existing federal, State, and local regulations as well as goals, policies, and actions in TOP 2050 would mitigate potential adverse impacts to the environment that may result from buildout of TOP 2050, including expansion of parks, recreational facilities, and multiuse trails.

Furthermore, subsequent environmental review would be required for development of park projects under the TOP 2050 Land Use Plan. Therefore, 868

impacts would be less than significant (Certified SEIR, pp. 5.16-12 – 5.16-14).

Project Impacts: As mentioned above, the Project would include recreational amenities to serve future residents, including a pool/spa, playground, shaded barbeque/picnic area, fitness stations, and open turf areas. These amenities are part of the Project; the disturbance footprint, construction techniques, and associated impacts have been accounted for within this Addendum (and associated technical analyses). Potential impacts addressed within this Addendum are substantiated to be less than significant, or less than significant as mitigated. As such, implementation of the Project would not result in any adverse physical effects on the environment due to the construction of recreational facilities. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

a. Conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities?
Summary of Certified SEIR Finding: TOP 2050 includes policies to encourage and provide access to the regional transit network, to enhance connectivity to the City’s nonmotorized transportation network, and proposes the changes to the Mobility Element that have the potential to affect infrastructure projects identified in the Regional Transportation Plan. As such, Certified SEIR Section 5.17, Transportation, concluded that implementation of TOP 2050 would not conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities (Certified SEIR, pp.

5.17-18 – 5.17-23).

Project Impacts:

Project Trip Generation
Trip generation represents the amount of traffic that is attracted to and produced by a development project. The Project’s Trip Generation Assessment compared the trips anticipated from the proposed Project with those of the approved elementary school use, as shown in Table17-1.

Alternative Transportation
The Project does not propose elements or aspects that would conflict with adopted alternative transportation policies. Transit services are currently provided to the City and the Project vicinity by Omnitrans, with a stop located at the corner of Eucalyptus Avenue and Hamner Avenue, less than 1,000 feet from the Project site. The Project would provide internal driveways and pedestrian paths that connect to the existing street and sidewalk network surrounding the Project site.

Transit agencies routinely review and adjust their ridership schedules to accommodate shifts in demand for services. As part of the City’s standard development review processes, the need for transit-related facilities, bicycle, and pedestrian access would be coordinated between the City and the Applicant.

The Project would not interfere with the City Multipurpose Trails and Bikeway Corridor Plan. The Project would provide internal and perimeter pedestrian and bicycle amenities consistent with provisions of Esperanza Specific Plan and City Conditions of Approval.

Goals and Policies
Applicable goals and policies addressing the circulation system are established under TOP 2050. Project consistency with applicable provisions of TOP 2050 is summarized in Table 5 of the VMT Analysis provided as Addendum Appendix K2.

As presented therein, no conflicts would occur.

Conclusion
Based on the preceding, the potential for the Project to conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities would be less than significant. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

b. Conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b)?
Summary of Certified SEIR Finding: The Certified SEIR concluded that there is a net increase in citywide Boundary VMT primarily due to the increase in population accommodated by TOP 2050. Mitigation Measure T-1 would reduce potential impacts for future development projects to the extent feasible. Future development projects consistent with TOP 2050 would need to consider transportation demand management (TDM) measures consistent with those identified in the Mobility Element. TDM techniques include incentives to use transit; incentives to form carpools rather than drive alone; and making home, work, and shopping closer together to shorten travel distances. Because the VMT impact is citywide, mitigation measures to reduce VMT would need to focus on changing or improving the citywide travel patterns, transportation network, or infrastructure.

Given the uncertainty of the effectiveness of implementing these types of mitigation measures at a citywide level and of their effectiveness at reducing citywide VMT, VMT impacts would remain significant and unavoidable (Certified SEIR, p. 5.17-34).

Project Impacts: The City of Ontario developed and adopted their own VMT methodologies and thresholds (Resolution No. 2020-071) (City Guidelines) in June 2020. Projects that do not result in significant VMT impacts per City Guidelines would not conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b).

Project-generated VMT has been estimated using the Origin/Destination Method and Boundary Method, consistent with City Guidelines, VMT has been presented as total VMT and total VMT per Service Population (i.e., population and employees). Total VMT encompasses all VMT generated in the City of Ontario or by the Project on a typical weekday, while total VMT per Service Population (SP) 872

is an efficiency metric representing VMT generated on a typical weekday per person who resides and/or works in the City or who resides within the Project.

The City of Ontario has adopted the following thresholds of significance related to VMT for land use projects:
• A significant impact would occur if the project VMT per SP exceeds the Citywide average VMP per SP under General Plan Buildout Conditions. • A significant impact would occur if the project caused total daily VMT per SP within the City to be higher than the no project scenario under cumulative conditions.

The City of Ontario's average VMT per SP under General Plan Buildout conditions was calculated using the TOP General Plan Buildout (2050) model, and is presented in Table 17-2.

Based on the preceding, the following findings are made:
• Project-generated VMT per SP was found to be below the City’s adopted impact threshold of Citywide average VMT per SP under General Plan Buildout Conditions and is considered less than significant.
• Total daily VMT per SP within the City is forecast to remain unchanged with the addition of the proposed Project and is considered less than significant.

Based on the preceding discussion, no new significant, substantially increased, or substantially different VMT impacts would occur as a result of the Project. No changed or new information has been identified to indicate that any potential VMT impacts resulting from the Project would be different from those that would result under the Certified SEIR.

c. Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)?
d. Result in inadequate emergency access?
Summary of Certified SEIR Finding: The Certified SEIR concluded that buildout of the City pursuant to TOP 2050 would result in changes to the circulation network.

Such changes would however be implemented consistent with City roadway classification and roadway design standards, acting to preclude potential design hazards. Additionally, City Design Review processes ensure that adequate emergency access is provided for all new development projects. On this basis, there would be no impacts related to hazardous design features, or emergency access provisions (Certified SEIR, pp. 5.17-25, 5.17-26).

Project Impacts: The Project does not propose elements or aspects that would substantially increase transportation/traffic hazards. Moreover, all improvements under the Project would be designed and implemented consistent with City traffic engineering and safety standards, thereby minimizing the potential to result in or cause hazardous traffic/transportation conditions.

The Project would generate urban traffic comparable to and compatible with the vehicle mix and vehicle categories present within the area roadway system.

Residential uses proposed by the Project would therefore not cause or result in incompatible vehicle movements or traffic that would substantively increase hazards. Further, based on the projected trip generation under the Project, no new or different traffic hazards would occur when compared to the Certified SEIR.

All Project plans would be reviewed and approved by the Ontario Fire Department to ensure design standards related to adequate emergency access are met. Based on the preceding, the potential for the Project to substantially increase hazards due to a geometric design feature, incompatible uses, or inadequate emergency access is considered less than significant. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR. 878

17. TRIBAL CULTURAL RESOURCES. Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is:
a. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code section 5020.1(k)?
b. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision(c) of Public Resources Code section 5024.1. In applying the criteria set forth in subdivision(c) of Public Resources Code section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.

Summary of Certified SEIR Finding: The Certified SEIR concluded that grading and construction activities in undeveloped areas or redevelopment that requires deeper soil excavation than in the past have the potential to disturb tribal cultural resources. With the implementation of mitigation, the Certified SEIR concluded that impacts to prehistoric archeological resources, including tribal cultural resources, would be less than significant (Certified SEIR, pp. 5.18-8 – 5.18-11).

Project Impacts: No resources that are eligible for listing in the California Register of Historical Resources or in a local register of historical resources as defined by Public Resources Code Section 5020.1(k) were identified as part of the Cultural Resources Study conducted for the Project site. Implementation of the Project would not result in a substantial adverse change in the significance of a listed historical resource.

Senate Bill 18 (SB 18) requires local (city and county) governments to consult with California Native American tribes to aid in the protection of traditional tribal cultural places (“cultural places”) through local land use planning. The consultation and notice requirements apply to adoption and amendment of both general plans (defined in Government Code Section 65300 et seq.) and specific plans (defined in Government Code 65450 et seq.), and not the CEQA process. To this end, outreach letters were sent to 21 individuals representing local Native American tribal groups to elicit information on Native American cultural resources that may be in the vicinity of the Project site. In response, the Gabrieleno Band of Mission Indians – Kizh Nation (Kizh Nation) requested consultation with the City.

Similar to the findings of the Certified SEIR, the Kizh Nation has requested mitigation measures be implemented to preclude impacts in this regard. Specifically, the Tribe has proposed Measures 18-1 through 18-3, which require Native American monitoring of ground-disturbing activities, as well as protocol for the treatment and disposition of tribal cultural resources should they be discovered during Project development. These Tribe-specific measures shall replace Certified SEIR Measures 5-4, TCR-1, and TCR-2.

As a result, consistent with the findings of the Certified SEIR, mitigation would preclude potential impacts to tribal cultural resources as defined in Public Resources Code 5024.1(c). Therefore, the Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

that the developer, City, Tribes,
and project archaeologist will
follow in the event of
inadvertent cultural resources
discoveries, including any newly
discovered cultural resource
deposits that shall be subject to
a cultural resource’s evaluation.

At least 30 days prior to application for
a grading permit and before any brush
clearance, grading, excavation,
and/or ground disturbing activities on
the site, the developer shall retain a
tribal cultural monitor to monitor all
ground-disturbing activities in an effort
to identify any unknown
archaeological resources.

Pursuant to the AMP, a tribal monitor
from the consulting tribe shall be
present during the initial grading
activities. If tribal resources are found
during grubbing activities, the tribal
monitoring shall be present during site
grading activities.

TCR-2 Treatment and Disposition of
Cultural Resources. In the event that
Native American cultural resources are
inadvertently discovered during the
course of any ground-disturbing
activities, including but not limited to
brush clearance, grading, trenching,
etc., for the proposed project, the
following procedures will be carried
out for treatment and disposition of the
discoveries:

1. Temporary Curation and
Storage: During the course of
construction, all discovered
resources shall be temporarily
curated in a secure location onsite or at the offices of the Revised. At the request of the Kizh
Nation (the consulting Tribe), Measure
TCR-2 is replaced with Measures 18-2
and 18-3.
18-2: Unanticipated Discovery of Tribal
Cultural Resource Objects (NonFunerary/Non-Ceremonial) A. Upon discovery of any TCRs, all
construction activities in the
immediate vicinity of the discovery
shall cease (i.e., not less than the
surrounding 50 feet) and shall not
resume until the discovered TCR has
been fully assessed by the Kizh monitor
and/or Kizh archaeologist. The Kizh will
recover and retain all discovered TCRs

project archaeologist. The
removal of any artifacts from the
project site will need to be
thoroughly inventoried with
tribal monitor oversight of the
process;

2. Treatment and Final Disposition:

The landowner(s) shall relinquish
ownership of all cultural
resources, including sacred
items, burial goods, and all
archaeological artifacts and
nonhuman remains as part of
the required mitigation for
impacts to cultural resources.

The applicant shall relinquish the
artifacts through one or more of
the following methods and
provide the City of Ontario with
evidence of same:
a. Accommodate the process
for on-site reburial of the
discovered items with the
consulting Native American
tribes or bands. This shall
include measures and
provisions to protect the
future reburial area from any
future impacts. Reburial shall
not occur until all cataloging,
basic analysis, other analyses
as recommended by the
project archaeologist and
approved by consulting
tribes, and basic recordation
have been completed; all
documentation should be at
a level of standard
professional practice to allow
the writing of a report of
professional quality;
in the form and/or manner the Tribe
deems appropriate, in the Tribe’s sole
discretion, and for any purpose the
Tribe deems appropriate, including for
educational, cultural, and/or historic
purposes.
18-3: Unanticipated Discovery of
Human Remains and Associated
Funerary or Ceremonial Objects
A. Native American human remains
are defined in PRC 5097.98(d)(1) as an
inhumation or cremation, and in any
state of decomposition or skeletal
completeness. Funerary objects,
called associated grave goods in
Public Resources Code Section
5097.98, are also to be treated
according to this statute.

B. If Native American human remains
and/or grave goods are discovered or
recognized on the Project site, then
Public Resource Code 5097.9 as well as
Health and Safety Code Section
7050.5 shall be followed.

C. Human remains and grave/burial
goods shall be treated alike per
California Public Resources Code
Section 5097.98(d)(1) and (2).

Information presented within the following discussions was obtained from the following Project-specific analyses:
• Water System Analysis For The Esperanza PA 11 Project in Ontario Ranch in the City of Ontario (Dexter Wilson Engineering, Inc.) April 17, 2025. • Sewer System Analysis for the Esperanza PA 11 Project in Ontario Ranch in the City Of Ontario (Dexter Wilson Engineering, Inc.) April 17, 2025.

These reports are provided as Appendices L and M, respectively, to this Addendum.
a. Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects?
Summary of Certified SEIR Finding: The Certified SEIR concluded that, although buildout of TOP 2050 would generate additional wastewater, it would be adequately treated in accordance with Regional Water Quality Control Board and California Department of Public Health requirements. City sanitary sewer 887

systems, and stormwater management would be expanded to accommodate growth associated with the buildout of TOP 2050.

Other utilities systems would be extended and improved consistent with purveyor master plans and as warranted by market conditions. Compliance with regulatory requirements and standard conditions of approval acts to reduce impacts on utilities systems generally, improve system efficiencies, and reduce system maintenance requirements. Collectively, this diminishes the requirement to construct new systems or replace existing systems.

Construction of utilities systems serving the City under TOP 2050 buildout conditions would not result in substantially different impacts than would result from development of TOP 2050 land uses generally.

The Certified SEIR concluded that with implementation of regulatory requirements and standard conditions of approval, the potential for TOP 2050 to require or result in the relocation or construction of new or expanded utilities systems, the construction or relocation of which would result in adverse environmental impacts would be less than significant (Certified SEIR, p. 5.19-11).

Project Impacts:

Water and Wastewater
The Project would include the installation of water and wastewater lines within the Project site. The Project on-site water system would connect to two existing 8-inch water lines in Amherst Avenue and Chatham Street, adjacent to the site. The Water System Analysis concluded that the existing and proposed water infrastructure has adequate capacity to serve the Project and necessary fire flow.

The proposed on-site sewer collection system would connect to an existing 8-inch line located in south Amherst Avenue, adjacent to the site. The Sewer System Analysis concluded that all existing and proposed sewer lines have adequate capacity to convey peak flows from existing development plus the proposed Project while maintaining City criteria.

Page 140 of 152 ends

Although the Project would result in new water and wastewater line connections, these connections would occur on-site and would be part of the Project’s construction phase, which is evaluated throughout this Addendum. The construction of the Project’s water and wastewater lines necessary to serve the Project would not result in any significant physical effects on the environment that are not already identified and disclosed as part of this Addendum. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Stormwater Drainage
The Project site currently drains in a southwesterly direction towards the intersection of Eucalyptus Avenue and Amherst Avenue where an on-site detention basin is located. The basin has a 36-inch inlet that joins a public storm drain in Amherst Avenue. The Project would implement an on-site storm drain system that generally maintains the existing drainage pattern and connects to the existing storm drain in Amherst Avenue. The Projects on-site storm drainage system would function as a flow restriction by oversizing the on-site capacity and providing on-site storage to ensure outflow would be consistent with the capacity of the surrounding storm drainage system. As such, the Project would not require relocation or construction of new or expanded storm water drainage infrastructure which could cause significant environmental effects. The Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

Dry Utilities
Dry utilities serving the Project area include Southern California Edison, Southern California Gas Company (although natural gas service is not required for the Project), and various telecommunication providers. The Project would include installation of on-site dry utility infrastructure that is anticipated to connect with the existing infrastructure available in the vicinity.

Connection is inherent to the Project’s construction phase and has been evaluated throughout this Addendum. The Project would not result in any new, 889

b. Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? Summary of Certified SEIR Finding: The City of Ontario 2020 Urban Water Management Plan (UWMP) substantiates that there would be sufficient and reliable water supplies available to the City through 2045. The Certified SEIR concludes that buildout of the City under TOP 2050 would incrementally increase water demands. However, water demands of the City would remain below 2020 UWMP water demand projections. On this basis, there would be sufficient water supplies available to the City under TOP 2050 buildout conditions. The potential for there to be insufficient water supplies available to serve the City and reasonably foreseeable future development during normal, dry and multiple dry years is therefore considered less than significant (Certified SEIR, pp. 5.19-30, 5.19- 31).

Project Impacts: Ontario Municipal Utilities Company (OMUC) is responsible for supplying potable water to the Project site. The UWMP includes an analysis of water supply reliability projected through 2045 under normal years, single dry year, and multiple dry years. As stated above, the City is anticipated to have adequate water supplies to meet all its demands from the implementation of TOP 2050 at buildout until the year 2045 under a normal year, single dry year, and multiple dry years.

Based on the Water System Analysis calculations, the water demand of the proposed residential uses can be compared to that of the approved school use, as shown in Table 19-1.

2 Dexter Wilson, 2025a
As shown above, the Project would result in an increased water demand of 16,933 gpd.

The Water Supply Assessment (WSA) prepared for the New Model Colony (NMC) determined that water demand for the NMC, as a whole, would be approximately 10.2 mgd. The City’s projected 2025 water demand is 100.9 mgd, and the 2025 supply is projected at 166.1 mgd (Esperanza SP DEIR, p.III-12-14).

Based on the City’s surplus water supply, as determined by the WSA for the NMC, sufficient water supply exists to accommodate the Project-related increase. As such, the Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

c. Result in a determination by the wastewater treatment provider that serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
Summary of Certified SEIR Finding: The Certified SEIR recognizes that buildout of the City under TOP 2050 would result in increased wastewater treatment demands. However, existing wastewater treatment plants have excess capacity sufficient to meet these increased demands. Planned wastewater treatment 891

plant expansion would provide additional capacity available to serve the City under TOP 2050 buildout conditions. Treated wastewater meets or exceeds RWQCB and NPDES standards and requirements. On this basis, the Certified SEIR concluded that the potential for buildout of City under TOP 2050 to result in or cause insufficient or inadequate wastewater treatment would be less than significant.

Project Impacts: Based on the Sewer System Analysis prepared for the Project, Table 19-2 presents a comparison of the wastewater generation associated with the approved elementary school and the Project.

2 Dexter Wilson, 2025b
As shown above, the Project would result in a wastewater generation increase of 8,014 gpd when compared to the approved school use.

Wastewater from the site would be treated at IEUA Regional Water Recycling Plant No. 5 (RP-5) located in Chino. RP-5 currently treats about 9 million gallons per day (mgd), with a total treatment capacity of 16.3 mgd. RP-5 is currently undergoing an expansion which will increase capacity to 22.5 mgd. Ultimately, RP-5 will treat 30 mgd with a peak flow of 60 mgd. (IEUA, 2024) The Project increase represents approximately 0.05 percent of RP-5’s current treatment capacity. Given the existing freeboard, in addition to the ongoing expansion of RP-5, the IEUA’s existing wastewater treatment facilities are anticipated to have adequate capacity to serve the Project’s demand in addition to its existing commitments. Therefore, the Project would not result in any new, increased or substantially different impacts, other than those previously considered and addressed in the Certified SEIR.

d. Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals?
e. Comply with federal, state, and local management and reduction statutes and regulations related to solid waste?
Summary of Certified SEIR Finding: The Certified SEIR concluded that buildout of TOP 2050 would be served by landfills with sufficient permitted capacities to accommodate all solid waste disposal needs. Additionally, no conflicts with federal, State, and local management and reduction statutes and regulations related to solid waste were identified. The Certified SEIR determined that impacts related to solid waste would be less than significant (Certified SEIR, p. 5.17-31).

Project Impacts: Using a solid waste generation factor from CalRecycle, the operational solid waste anticipated from the proposed Project can be compared to that of the approved school use, as evaluated in the Esperanza Specific Plan DEIR (p. III-12-16). This comparison is presented in Table 19-3.

Solid waste generation anticipated by the Project represents approximately 0.065 percent (0.32 ton/day) of the current daily maximum throughput for the Badlands Landfill and 0.002 percent of the current daily maximum throughput for the El Sobrante Landfill. Given the excess daily capacity, solid waste generated by the proposed uses can be accommodated by either of these existing landfill facilities.

Additionally, the Project would comply with applicable solid waste management and reduction statutes and regulations (summarized below), acting to reduce solid waste management impacts of the Project.
• City of Ontario Construction & Demolition Recycling Plan (CDRP) Pursuant to Ontario Municipal Ordinance (OMC) Sec. 6-3.602 Construction & Demolition Recycling Plan and the 2016 California Green Building Standards Code (CALGreen), all building and demolition permit applicants are required to prepare and submit a Construction & Demolition Recycling Plan (CDRP) and a CDRP Summary Report. OMC Sec. 6-3.602 and CALGreen require all construction and qualifying renovation and demolition projects to divert at least 65% of all generated waste materials. The City oversees compliance with OMC Sec. 6-3.602 and CALGreen construction waste diversion mandates. 894

• AB 939 - California Integrated Waste Management Act of 1989 Solid waste management is guided by the California Integrated Waste Management Act of 1989 (AB 939), which emphasizes resource conservation through reduction, recycling, and reuse of solid waste. AB 939 requires that localities conduct a Solid Waste Generation Study (SWGS) and develop a Source Reduction Recycling Element (SRRE), providing for a minimum 50 percent reduction in waste sent to landfills.

Diversion rates are calculated and tracked by the California Integrated Waste Management Board (Board). Alternatively, the Board can determine that a jurisdiction’s “good faith efforts” to implement comprehensive diversion programs have satisfied the requirement even if diversion levels are below 50 percent.

To reduce waste disposal, AB 939 requires every California city and county to divert 50 percent of its waste from landfills. Residential, commercial and governmental waste recycling programs in support of the SRRE have been implemented by the City. The City is currently meeting or exceeding all AB 939 solid waste diversion targets. • AB 341 - Commercial Recycling
Assembly Bill 341 mandates recycling for businesses producing four or more cubic yards of solid waste per week, and multifamily dwellings of five units or more. Under the law, business must separate recyclables from trash and then either subscribe to City of Ontario recycling services, self-haul their recyclables, or contract with a permitted private recycler. • SB 1383 - Organic Waste Management Requirements
SB 1383 establishes targets to achieve a 50 percent reduction in the level of the Statewide disposal of organic waste from the 2014 level by 2020 and a 75 percent reduction by 2025. The law grants CalRecycle the regulatory authority required to achieve the organic waste disposal reduction targets and establishes an additional target that not less than 20 percent of currently disposed edible food is recovered for human consumption by 2025.

The City is currently developing programs and strategies to address the requirements of SB 1383, the Project would be required to ultimately abide by those requirements.

As stated in the Certified SEIR, impacts to solid waste services and facilities from new development are further addressed through the payment of development impact fees as outlined in the City of Ontario Development Impact Fee Calculation and Nexus Fee Schedules. With the payment of required development impact fees and compliance with existing solid waste regulations, the Project would not result in any new or substantially increased solid waste impacts not previously identified within the Certified SEIR.

Based on the preceding, the Project would not generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals would be less than significant. Additionally, the Project would comply with applicable solid waste management and reduction statutes and regulations. On this basis, the Project would result in less than significant solid waste management impacts. The Project would not result in solid waste management impacts substantially greater than solid waste management impacts considered and addressed in the Certified SEIR.

wildfire or the uncontrolled spread of a wildfire?
c. Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment?
d. Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes?
Summary of Certified SEIR Finding: As discussed in the Certified SEIR, CAL FIRE has determined that the City contains no areas subject to very high wildfire risk. The City recognizes that even though fuel loading is light in Ontario and fire risk comes primarily from urban fires, not wildfires, there is some risk related to wildfires. There are many resources available to address wildland fires should they arise - CAL FIRE’s 2019 Strategic Fire Plan for California, the CFC, County of San Bernardino MJHMP, City of Ontario LHMP, and fire services from the City of Ontario Fire Department. With adherence to these building practices, development and infrastructure associated with TOP 2050 would not exacerbate risk or result in postwildfire hazards (e.g., landslides, mudflows, and flooding). In addition, TOP 2050 incorporates policies to prevent wildfire hazards and support the community during wildfire events (Certified SEIR, pp. 5.20-15, 5.20-16). On this basis, the Certified SEIR concluded that potential wildfire impacts resulting from TOP 2050 would be less than significant.

Project Impacts: Development of the site has been anticipated under TOP 2050.

By extension, potential wildfire impacts affecting the Project site are reflected in the assessment of wildfire impacts affecting the City under TOP 2050, as considered and addressed in the Certified SEIR. Per CAL FIRE, Fire Hazard Severity Zone Maps, the City and the Project site are not located within or near a state responsibility area, or within an area classified as a very high fire hazard severity zone.

Fire protection services for the Project site and vicinity are currently provided by the Ontario Fire Department. Adherence to Fire Department building and site 897

20.MANDATORY FINDINGS OF SIGNIFICANCE.
a. Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat or a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? b. Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current project, and the effects of probable future projects.)
c. Does the project have environmental effects that will cause substantial adverse effects on human beings, either directly or indirectly? Project Impacts: This Addendum defines, describes, compares, and contrasts potential environmental impacts of the Project in the context of the environmental impacts assessed in the Certified SEIR. In so doing, this Addendum substantiates consistency with applicable CEQA Guidelines provisions addressing preparation of an Addendum to a previously-Certified SEIR.

As supported by the discussions presented herein, the Project would not result in or cause any new significant impacts, substantively increased impacts, or 898

MM 3-1
Prior to discretionary approval by the City of Ontario for development projects subject to CEQA (California Environmental Quality Act) review (i.e., nonexempt projects), project applicants shall prepare and submit a technical assessment evaluating potential project construction-related air quality impacts to the City of Ontario Planning Department for review and approval. The evaluation shall be prepared in conformance with South Coast Air Quality Management District (South Coast AQMD) methodology for assessing air quality impacts. If construction-related criteria air pollutants are determined to have the potential to exceed the South Coast AQMD–adopted thresholds of significance, City of Ontario Building Department shall require feasible mitigation measures to reduce air quality emissions. Potential measures shall be incorporated as conditions of approval for a project and may include:
• Require fugitive dust control measures that exceed South Coast Air Quality Management District’s Rule 403, such as:
o Requiring use of nontoxic soil stabilizers to reduce wind erosion. o Applying water every four hours to active soil disturbing activities. o Tarping and/or maintaining a minimum of 24 inches of freeboard on trucks hauling dirt, sand, soil, or other loose materials. • Using construction equipment rated by the United States Environmental Protection Agency as having Tier 4 interim or higher exhaust emission limits. • Ensuring construction equipment is properly serviced and maintained to the manufacturer’s standards.
• Limiting nonessential idling of construction equipment to no more than five consecutive minutes.
• Using Super-Compliant VOC paints for coating of architectural surfaces whenever possible. A list of Super-Compliant architectural coating manufactures can be found on the South Coast Air Quality Management District’s website at: http://www.aqmd.gov/prdas/brochures/SuperCompliant_AIM.pdf.

There is a possibility of owl colonization within the project site prior to site grading.

To ensure that no direct loss of individuals occurs, mitigation will be carried prior to initiation of on-site grading activities for each development phase. A pre-construction survey for resident burrowing owls shall be conducted by a qualified biologist. The survey shall be conducted 30 days prior to construction activities. If grounddisturbing activities are delayed or suspended for more than 30 days after the preconstruction survey, the site shall be resurveyed for owls.

If owls are determined to be present within the construction footprint, they shall be captured and relocated. If non-breeding owls must be moved away from the disturbance area, passive relocation techniques will be used. The pre-construction survey and any relocation activity shall be conducted in accordance with the CDFG Report on Burrowing Owl Mitigation, 1995. According to CDFG guidelines, mitigation actions will be conducted from September 1 to January 31, which is prior to the nesting season. However, burrowing owl nesting activity is variable, and as such the time frame will be adjusted accordingly. Should eggs or fledglings be discovered in any owl burrow, the burrow cannot be disturbed (pursuant to CDFG guidelines) until Project Applicant

the young have hatched and fledged (matured to a stage that they can leave the nest on their own).

Occupied burrows shall not be disturbed during the nesting season (February 1 through August 31) unless a qualified biologist approved by the Department of Fish and Game verifies through non-invasive methods that either: a) the adult birds have not begun egg-laying and incubation; or b) the juveniles from the occupied burrows are foraging independently and are capable of independent survival. If a biologist is unable to verify one of the above conditions, then no disturbance shall occur within 300 feet of the burrowing owl’s nest during the breeding season to avoid abandonment of the young.

Passive relocation can be used to exclude owls from their burrows (outside the breeding season or once the young are able to leave the nest and fly) by installing one-way doors in burrow entrances. These one-way doors allow the owl to exit the burrow, but not enter it. These doors should be left in place 48 hours to ensure owls have left the burrow. Artificial burrows should be provided nearby. The project area should be monitored daily for one week to confirm owl use of burrows before excavating burrows in the impact area. Burrows should be excavated using hand tools and refilled to prevent reoccupation. Sections of flexible pipe should be inserted into the tunnels during excavation to maintain an escape route for any animals inside the burrow.

C. The monitor will complete daily monitoring logs that will provide descriptions of the relevant ground-disturbing activities, the type of construction activities performed, locations of ground-disturbing activities, soil types, cultural-related materials, and any other facts, conditions, materials, or discoveries of significance to the Tribe. Monitor logs will identify and describe any discovered TCRs, including but not limited to, Native American cultural and historical artifacts, remains, places of significance, etc. (collectively, tribal cultural resources, or “TCR”), as well as any discovered Native American (ancestral) human remains and burial goods. Copies of monitor logs will be provided to the Project Applicant/ Lead Agency upon written request to the Tribe.

D. On-site tribal monitoring shall conclude upon the latter of the following: (1) written confirmation to the Kizh from a designated point of contact for the Project Applicant/Lead Agency that all ground-disturbing activities and phases that may involve ground-disturbing activities on the Project site or in connection with the Project are complete; or (2) a determination and written notification by the Kizh to the Project Applicant/Lead Agency that no future, planned construction activity and/or development/ construction phase at the Project site possesses the potential to impact Kizh TCRs.

Section 1. Executive Summary
The Esperanza Specific Plan is a proposal for
the development of approximately 223 acres
located within the City of Ontario New Model
Colony (NMC) Ontario Ranch. The master
plan for Esperanza will provide for development
of a distinctive residential planned community
offering a variety of housing types within
walking distance to parks and private recreational
amenities. The regional context and local setting
of the Esperanza Specific Plan are illustrated in
Exhibit 1, “Regional Location Map” and Exhibit
2, “Vicinity Map.”
The Esperanza Specific Plan comprises all of
Planning Subarea 25 as depicted on the City of
Ontario New Model Colony (NMC) Ontario
Ranch General Plan Land Use Map. The
Esperanza Specific Plan reflects the current Land
Use Plan in The Ontario Plan (General Plan).

It encompasses the eastern edge of The Ontario
Ranch Master Planned Community. The Specific
Plan is bounded by Bellegrave Avenue to the
south, Milliken Hamner Avenue to the east,
and Mill Creek Avenue to the west. Old Edison
Road abuts the Specific Plan area on the north.

Approximately 174.10 net acres of Esperanza are
proposed for residential uses along with 9.89 net
acres of park uses.

The Esperanza Specific Plan establishes the
regulations and guidelines which will govern
development of the master planned community
within the Ontario Ranch General Plan. The
development plan as illustrated in Exhibit 3
“Land Use Plan,” is consistent with the goals
and policies of the NMC Ontario Ranch
General Plan combining livable residential
neighborhoods served by public and recreational
facilities as well as active open space offering
opportunities for social interaction among
residents.

Pedestrian accessibility is provided throughout
Esperanza, through a system of sidewalks
separated from the street by landscaped parkways
and landscaped buffer areas. Bicycle mobility
is provided within the community through a
system of on-street bicycle trails.

The NMC The Ontario Ranch General Plan,
adopted by the City of Ontario, designates
The Esperanza Specific Plan for development
of up to 1,456 residential dwelling units,
however, 46 161 residential dwelling units will
be developed within the Specific Plan area
originally anticipated to be a 10.02 acre school
site within Esperanza. On XX-XX-2020 10-20-
2020, a request to increase PA4 to 14DU/AC
was approved in order to accommodate a more
efficient, economical sized design, and more
appropriate product type. The increase allows for
the development of up to 1,640 1,652 units.

GoverningDocuments
Development of Esperanza will be governed by
the following: • The City of Ontario NMC Ontario Ranch
General Plan, as amended, which establishes
policies governing land use, circulation,
housing, conservation and open space,
noise, safety, and public facilities within the
Esperanza Specific Plan area.
• The Esperanza Specific Plan which includes
a Land Use Plan, Infrastructure Plan, Design
Guidelines, and Development Regulations.

Where the Esperanza Specific Plan is silent,
the City of Ontario Development Code shall
govern.
• The City of Ontario Subdivision Ordinance
regulating the subdivision of land within the
Esperanza Specific Plan area.
• A development agreement to include methods
for financing, acquisition, and construction of
infrastructure, acquisition and development
of parks and schools, as well as the provision
for housing opportunities consistent with the
regional housing needs assessment.
• Covenants, Conditions, and Restrictions
(CC&R’s) to be established by the developers
of Esperanza as a means of ensuring and
enforcing quality design and development of
the master planned community.

Introduction
The Esperanza Specific Plan (Specific Plan)
includes 223 acres of land designated for
residential uses as part of the Ontario Ranch
area within the City of Ontario. Esperanza, at
build out will be a residential master planned
community within the City of Ontario with a
traditional neighborhood design similar to that
found in older established communities.

2.1 Community Vision
and Objectives
The community vision for the Esperanza Specific
Plan is implemented through the application of
key design objectives guiding the development of
the Specific Plan as discussed below.

Objective: Create a Livable Environment
The Esperanza Specific Plan combines
residential, recreation and public facilities
designed to create a livable community and
includes features such as:
• A design which allows for alternative modes
of travel such as biking and walking.
• Opportunities for informal neighborhood
interaction.
• Diverse architectural design of a high quality.
• Connectivity among neighborhoods.
• Diversity and choice of housing types and
opportunities to address a variety of lifestyles
and economic segments of the marketplace.
• Residential neighborhoods developed
at a human scale oriented to pedestrian
activities with connectivity among residential
neighborhoods, parks, and schools.
• A simple and well-designed street system
providing street separated sidewalks and
active and passive recreational opportunities
allowing residents to experience increased
outdoor living opportunities.
• A variety of housing types incorporated
into the land use plan addressing lifestyle
considerations of singles, families, and empty
nesters.
• Residential neighborhoods designed around a
network of centrally located parks, promoting
outdoor activity and casual social interaction
among neighbors.

Objective: Plan for a Circulation System
Serving Motorists, Bicyclists and
Pedestrians
The circulation plan for the Esperanza Specific
Plan provides a comprehensive system of arterial,
collector, and local streets accommodating bicycle
and pedestrian travel as well as the safe and
efficient movement of automobiles within the
Specific Plan area:
• Street design includes landscaped buffer areas
and pedestrian walkways, separated from
the street, to create an intimate environment
promoting social interaction.
• Internal project streets are designed to slow
vehicular traffic through the use of traffic
calming devices such as a roundabout at “A”
Street adjacent to the neighborhood park,
landscaped areas adjacent to local streets, and
narrowed intersections to influence a driver’s
peripheral vision and encourage drivers to
proceed more slowly.
• A system of bikeways is integrated into the
design of the community to encourage bicycle
travel as an alternative to the automobile.
934
Section 2.

Introduction Section 2. Introduction

2.2 2.3
Objective: Provide for Adequate Public
Community Facilities
The Esperanza Specific Plan provides for the
development of needed public facilities to serve
the community as follows: • New water, sewer, and storm drain facilities to serve the Specific Plan area.
• New planned bike paths connecting to the
City of Ontario bikeway master plan bike
paths.

Objective: Provision of New Parks
and Open Space
New public park and open space amenities
are provided to enhance outdoor recreational
opportunities to residents of Esperanza and the
surrounding community. • Provision of approximately 9.89 acres of public parks, distributed throughout the
community, will offer active and passive
recreational opportunities within walking
distance of all residential areas.
• Approximately 4.4 acres adjacent to Mill
Creek Avenue, including a Southern
California Edison Easement, will be
landscaped for use as linear open space.
• Approximately 6.62 acres of landscaped open
space to include pedestrian trails adjacent to
public arterial and collector streets will be
provided
.
• A bicycle/pedestrian trail system will be
developed within the street system of the
Specific Plan area connecting the residential
areas of the Specific Plan to parks and points
surrounding the community providing
accessibility to bicyclists and pedestrians
throughout the community.

Objective: Promote Exceptional Architecture
and Site Planning
Diverse and varied architecture combined
with comprehensive site planning within
the Esperanza Specific Plan will produce
neighborhoods that have aesthetic and functional
harmony, preserve residents privacy, and
encourage neighborhood interaction. • Streets will be linked together in a manner, which is pedestrian friendly, but also autoaccessible connecting homes with other neighborhoods, open space, public facilities,
and recreational areas for residents to either
walk, bike, or drive to.
• A variety of housing types, including attached
and detached single family homes, will be
provided within the Specific Plan area, all
of which are located close to parks and open
space.
• Residential planning areas include a
variety of housing types oriented toward
the street adding interest and encouraging
neighborhood interaction along the street.
• Residential neighborhoods are designed with
houses addressing the street by: • Designing homes to a more human level with porches, stoops, and walkways
creating opportunities for neighborly
interaction.
• Homes fronting the street with garages
accessed from rear alleys.
• Minimizing views of garage doors through
setback requirements, location, design
elements, and landscaping.
• Incorporating varied architectural styles
and elements within each neighborhood.

2.2SpecificPlanPurpose
The City of Ontario will adopt the Esperanza
Specific Plan by ordinance thereby establishing
the land use plan, development standards,
infrastructure requirements, and implementation
requirements for the Specific Plan area. The
Esperanza Specific Plan establishes the type and
distribution of residential land uses, defines the
development regulations and design guidelines
for residential land use, establishes appropriate
locations for development of public parks,
and describes the infrastructure requirements
and the level of improvements necessary to
support development of the Specific Plan area.

The Esperanza Specific Plan establishes the
procedures and requirements to approve new
development within the Specific Plan area and
identifies, where applicable, City of Ontario
Development Code requirements.

2.3SpecificPlanProposal

2.3.1 Project Summary
The Esperanza Land Use Plan is described below
and in the Specific Plan “Statistical Summary,”
Table 1.

2.3.1.1 Residential Uses
Esperanza will provide for development of a
variety of residential housing types oriented
toward open space amenities and designed to
promote walkability and interaction among
residents. Residential development within the
approximately 223 acre Specific Plan area will
contain up to 1.594 1,652 residential dwelling
units, providing a mix of single family detached
and single family attached housing types as
described below. In the event Planning Area 11,
reserved as for a 10.02 acre school site, is not
purchased by the Mountain View School District
Planning Area 11 may revert to a residential
zoning district for development of up to 46 161
additional dwelling units subject to approval by
the City of a Specific Plan Amendment.

2.3.2.2 Residential Detached
Esperanza offers six different types of single
family detached residential products for
development within the Specific Plan area. • SFD Conventional – Conventional single family detached residential units are proposed
on lots ranging from 3,900 square feet to
4,900 square feet in size. Vehicular access is
provided from interior streets and garages
are set back from the front of the residence
emphasizing the architectural elements
forming the streetscene. These residential
types will be developed at density levels
between 5.56 to 6.18 dwelling units per net
acre.
• SFD Cottage – Alley served single family
detached residential dwelling units will be
developed in two planning areas designed
with an architectural orientation to the street
by locating garages to the rear of residential
units. Alley loaded residential areas will be
developed at an average density of 7.89
dwelling units per net acre with a minimum
lot size of 2,400 square feet.
• SFD 2 Pack – Residential single family
detached development on minimum lots of
3,400 square feet in size will be developed in
a 2 Pack configuration. Residential 2 Pack
housing will be developed at a density of 6.84
dwelling units per net acre. Garages within
this housing type are alternately placed to the
rear of the lot or placed a significant distance
from the street maintaining an architecture
forward streetscene.
935
Section 2. Introduction Section 2. Introduction

2.4 2.5
• SFD Courtyard – Two types of single
family detached courtyard housing types
are planned for Esperanza. Courtyard
single family residential consisting of four
units per courtyard will be developed at
approximately 8.9 dwelling units per net
acre. This type of housing will be developed
around a 1 acre public park and will be
served by public streets with private drive
aisles accessing residential units developed
around a common motorcourt. Courtyard
single family residential courts of six units per
courtyard will be developed at approximately

7.48 dwelling units per net acre. This type of
courtyard housing will be developed around
private streets and parks with private drive
aisles serving residential units developed
around a common motorcourt. The courtyard
design planned for both housing types places
garages in alternating side on and street facing
conditions either minimizing or eliminating
visibility of garages from the street.

2.3.1.3 Residential Attached
Two types of single family attached residential
development products are planned within
Esperanza. Alley loaded row townhomes
designed around a private common green will be
developed at approximately 14.05 dwelling units
per net acre within PA 3 and at approximately

16.07 dwelling units per net acre in PA 11.

Single family attached motorcourt townhomes
will be developed at approximately 13.76
dwelling units per net acre. The motorcourt
townhome residential housing type will be
served by private streets with drive aisles
providing access to a motorcourt serving 10 to 12
residential dwelling units. Both the alley loaded
row townhome and the motorcourt townhome
residential housing types are designed with
garages located to the rear or turned to side on to
the street preserving an architecturally interesting
streetscene.

2.3.1.4 Parks, Trails, and Open
Space
A centrally located 5.36 acre neighborhood
park is planned to serve the Specific Plan area
providing opportunities for informal active
recreation such as soccer and baseball. Four
additional parks ranging in size from .84 to

1.39 acres are provided offering opportunities
for active and passive recreation and informal
gathering among neighbors. Approximately 6.62
acres of the Specific Plan area will be developed
as enhanced landscaped parkways along major
streets serving the community. These enhanced
parkways will include pedestrian walkways
providing connectivity to and from the Specific
Plan area and to the pedestrian network to be
developed within the community, connecting all
residential neighborhoods to parks. Within the
townhome residential areas, private open space as
well as private active recreation centers, including
swimming pools and spas, will be provided.

2.4 Authority and
Requirements

2.4.1 Authority
State of California Government Code, Title
7, Division 1, Chapter 3, Article 8, Section
65450-57 grants authority to cities to adopt
Specific Plans for purposes of implementing
the goals and policies of their General Plans.

The Government Code specifies that Specific
Plans may be adopted either by resolution
or by ordinance and that the Specific Plan is
required to be consistent with the General Plan.

The City of Ontario will adopt the Esperanza
Specific Plan by ordinance thereby establishing
the zoning regulations for development of the
Specific Plan area. The requirements of the
Esperanza Specific Plan shall take precedence
over the City of Ontario Development Code. In
instances where the Esperanza Specific Plan is
silent, the City of Ontario Development Code
shall prevail.

2.4.2 Requirements of
the Specific Plan
California Government Code Section 65451
sets forth the minimum requirements and review
procedures for Specific Plans as follows.

A Specific Plan shall include a text and a
diagram or diagrams, which specify all of the
following in detail:

1. The distribution, location, and extent of the
uses of land, including open space, within the
area covered by the plan;

2. The proposed distribution, location, and
extent and intensity of major components
of public and private transportation, sewage,
water, drainage, solid waste disposal, energy,
and other essential facilities proposed to be
located within the area covered by the plan
and needed to support the land uses described
in the plan;

3. Standards and criteria by which
improvements will proceed, and standards for
the conservation, development, and utilization
of natural resources, where applicable;

4. A program of implementation measures
including regulations, programs, public works
projects and the financing measures necessary
to carry out paragraphs 1, 2, and 3 above.

5. A statement of the relationship of the Specific
Plan to the General Plan.

The Esperanza Specific Plan meets the
requirements of the State of California
Government Code.

NOTES:

1. Net acres excludes all streets and uses listed
as “Other Uses” but includes interior local
streets and drive aisles.

2.5 Development Approval
Components
The components of the development approval
process for Esperanza are discussed below.

2.5.1 Specific Plan
The Esperanza Specific Plan, when adopted,
provides the zoning for the Specific Plan area.

It serves as a “blueprint” for development by
establishing the distribution of land use and
criteria for development as set forth herein. The
Esperanza Specific Plan also serves as the legal
document to implement the City’s General Plan.

2.5.2 Development
Agreement
Unless done in a coordinated manner and with
adequate fiscal planning, development projects
within the NMC Ontario Ranch are likely to
present a challenge in their implementation
because of the lack of existing public facilities
including street, sewerage, transportation,
drinking water, school and utility facilities.

California law has established a mechanism
for ensuring the adequate provision of such
facilities while at the same time providing
assurances to applicants that, upon approval
of the project, the applicants can proceed with
their projects. Approval of this Specific Plan
without a development agreement may result in
a waste of resources, escalate the cost of housing
to the consumer, and discourage investment in
and commitment to comprehensive planning
as envisioned by the City, which seeks to make
maximum efficient utilization of resources at the
least economic cost to the public.

Therefore, a statutory development agreement,
authorized pursuant to California Government
Code sections 65864 et seq., shall be required
as part of the approval of this Specific Plan. For
the above-mentioned reasons, the development
agreement for this Specific Plan shall include,
among other things, methods for financing
acquisition and construction of infrastructure,
acquisition and development of adequate levels
of parkland, and schools, as well as the provision
of adequate housing opportunities for various
segments of the community consistent with
the regional housing needs assessment. Such
development agreement shall have been fully
approved before the issuance of the first building
permit for this project.

2.5.3 Subdivision Maps
A tentative tract map(s) will be approved by
the City of Ontario for the Specific Plan area
indicating the approximate location of lot lines,
streets, and proposed grading. Following approval
by the City of the tentative tract map(s), a
final map(s) will be prepared. The final map(s)
becomes a legal document that is recorded and
defines legal parcels and lots that can be sold for
development.

2.5.4 Development Plan
Review
All development proposals for individual
Planning Areas within the Specific Plan will be
subject to the Development Plan Review process
pursuant to Article 8 of the City’s Development
Code.

2.6 CEQA Compliance
A Project Environmental Impact Report
(EIR) prepared by the City of Ontario for the
Esperanza Specific Plan, in accordance with
the California Environmental Quality Act
(CEQA), addresses impacts associated with the
Specific Plan and subdivision map(s). The EIR
recommends mitigation measures to reduce
impacts of the project to a less than significant
level. The EIR has been prepared as a basis for
the environmental review for all subsequent
discretionary and ministerial actions.

2.7 Relationship To General
Plan And Zoning
The City of Ontario NMC Ontario Ranch
General Plan designates the Specific Plan area
for development of the following land uses:

The General Plan establishes a target
development capacity of 1.456 1,652 residential
dwelling units as further described below:

3.1 Section 2. Introduction

2.8 The General Plan allows for development of
multi-family residential units as small lot, single
family detached units with a variety of parcel
sizes and product types on property designated
for multi-family uses, including “ResidentialMedium” and “Residential-High” density housing.

The City of Ontario has pre-zoned the Specific
Plan area as SP/AG (Specific Plan AG preserve).

The zoning designation of “SP” requires the
Specific Plan area to implement the objectives
of the NMC Ontario Ranch General Plan land
uses.

The Esperanza Specific Plan is designed to
meet the requirements of the State of California
Government Code and the City of Ontario
NMC Ontario Ranch General Plan. The City of
Ontario will adopt the Esperanza Specific Plan
by ordinance, thereby establishing the zoning
regulations for the development of the Specific
Plan area. The requirements of the Specific
Plan shall take precedence over the City of
Ontario Development Code. In instances where
the Specific Plan is silent, the City of Ontario
Development Code shall prevail.

Section 3. EExisstingg CCondition onditionss

3.7.1 Water
The Specific Plan area is located within the
925’ Zone. The City of Ontario does not have
water facilities in the vicinity of the project.

The nearest City of Ontario water mains are in
Riverside Drive, approximately 1.5 miles north of
the Specific Plan area. These existing water mains
have not been sized to serve development in the
925’ Zone. On site residential use on the site are
served by private wells. Existing well locations
within the Specific Plan area are illustrated on
Exhibit 7, “Existing Site Topography and Well
Locations.” A well use/destruction plan and
schedule for all existing private or agricultural
wells shall be submitted prior to issuance of
permits for any construction activity. If a
private well is actively used for water supply,
the developer shall submit a plan to abandon
the well and connect residential users to the
City’s domestic water system and agricultural
users to the City’s recycled water system when
available. Well destruction requires permitting
from the County Health Department. A copy
of the permit and Well Completion Report
DWR form 188 shall be provided to the City’s
Development Engineering Department and
the Utilities Engineering Department prior to
issuance of grading and/or building permits.

If the developer proposes temporary use of an
existing agricultural well for purposes other
than agriculture, such as grading or dust control
during project construction, the developer shall
make a formal request to the City of Ontario
for such use prior to issuance of permits for
the construction activity. Upon approval, the
developer shall enter into an agreement with the
City of Ontario and pay any applicable fees as set
forth by the agreement.

An existing 16” high-pressure water main is
located along the east side of Milliken Hamner
Avenue, adjacent to the Specific Plan area, in
the County of Riverside, and is owned by Jurupa
Community Services District, ( JCSD). JCSD
also owns a 30” water main in Bellegrave Avenue
east of Milliken Hamner Avenue and a 30” water
main in Hamner Avenue south of Bellegrave
Avenue which provides water to the existing
residential areas on the south side of Bellegrave
Avenue.

3.7.2 Sewer
The City of Ontario does not have sewer facilities
in the vicinity of the Specific Plan area. Existing
on site residences utilize private septic systems.

Prior to grading operations, existing septic tanks
and subsurface disposal fields will need to be
abandoned in accordance with Department of
Health Services requirements. An existing 42”
Santa Ana Regional Interceptor (SARI) sewer
main extends southerly in Hamner Avenue south
of Bellegrave Avenue. The SARI line is primarily
available for industrial wastewater, which is
conveyed to Orange County for treatment and
disposal. JCSD is currently utilizing the SARI
line for the disposal of residential wastewater,
and has excess capacity for this purpose.

3.7.3 Drainage
The County Line Channel is located within
Bellegrave Avenue. The channel is a City of
Ontario Master Plan facility intended to carry
urban runoff from those properties tributary to
the north, to the Cucamonga Creek Channel.

With the exception of the County Line Channel,
the existing storm drain system throughout
the Specific Plan area, is generally unimproved
and consists primarily of open earthen swales
along area roadways and the earthen drainage
interceptor ditch paralleling the southerly
boundary of the Specific Plan area which outlets
into the existing drainage basin located at the
southwest corner of the site. The drainage basin
outlets into an existing Riverside County storm
drain line in Mill Creek Avenue, formerly known
as Cleveland Avenue. The on site basin and
the connection to the Riverside County storm
drain line are interim improvements. Upon
development of the Specific Plan area the basin
will be eliminated and the storm flows from the
Specific Plan area will be tributary to the County
Line Channel.

3.7.4 Recycled Water
The Specific Plan area is located within the
930 Zone. The City of Ontario does not have
recycled water facilities in the vicinity of the
project. As a part of the development of the
Specific Plan area, the construction of new
recycled water system facilities will be required
by the developer consistent with the City’s
approved Recycled Water Master Plan.

3.7.5 Electricity
The Esperanza Specific Plan is located within the
service territory of Southern California Edison
Company.

3.7.6 Natural Gas
The Southern California Gas Company provides
natural gas service within the Specific Plan area.

Facilities in this area include an existing 6-inch
main on Milliken Hamner Avenue; an existing
2-inch main on Eucalyptus Avenue; and an
existing 2inch main on Cleveland Avenue (future
Mill Creek Avenue).

3.7.7 Communication
Systems
Verizon provides telephone service within the
Specific Plan area.

3.7.8 Solid Waste
The City of Ontario Public Works Agency
currently, by request, provides solid waste
collection and disposal to the NMC Ontario
Ranch.

3.8Hydrology
Since most of the Specific Plan area has been
in agricultural use, only a limited portion of
the Specific Plan area is now covered with
impervious surfaces. Normal rainfall to the area
is able to percolate through on-site soils and does
not result in high volumes of surface runoff as
is typically associated with urban use. During
periods of heavy rainfall, when ground surfaces
are saturated, surface runoff is collected in the
existing storm drains, culverts, and retention
basins located within the Specific Plan area.

With the exception of major regional flood
control channels such as the Cucamonga
Creek Channel, intended primarily to carry
urban runoff, the existing storm drain system
throughout the Specific Plan area is generally
unimproved and consists primarily of open
earthen swales along area roadways or curbed
roadway surfaces.

Ground waters within the NMC Ontario Ranch
,
as a whole, contain high concentrations of salt,
attributable to historic agricultural activities
such as dairy farming. The high organic content
of on-site soils has contributed incrementally
to the degradation of surface and groundwater
quality. Removal of the organic materials, which
constitute by-products of those dairy operations,
and compliance with National Pollution
Discharge Elimination System (NPDES) and
other storm water permit requirements, will
beneficially impact regional water quality.

3.9GeologyAnd Soils
The City of Ontario NMC Ontario Ranch
General Plan EIR identifies the Specific Plan
area as underlain by Pleistocene age (older
than 12,000 years) and Holocene age (less than
12,000 years old) alluvial deposits. The youngest
surficial deposit is eolian sands (Qhs), comprising
wind-blown sands having fine- to medium-sized
grains.
941
Section 4.

Land Use

4.1 Section 3. Existing Conditions

3.8 These loose sands form sheets and low-dune
deposits that have been stabilized by vegetation.

These deposits are exposed in the eastern portion
of the NMC Ontario Ranch area and extend
westward to an area defined generally by a
diagonal line extending from Harrison Avenue,
within Riverside County, on the south to
Vineyard Avenue on the north.

It is expected that most of these materials will
be uncemented and subject to consolidation
when saturated under structural loads. Erosion
potential is considered high. Foundation and
backfill suitability should be satisfactory with
proper over-excavation, mixing with a finergrained binder material, and compaction.

The Specific Plan area contains delhi series soils,
as mapped by the United States Department of
Agriculture, Soil Conservation Service in 1971
and 1980. Delhi series soils have been used for
agriculture, primarily for grapes and citrus, since
the 1800’s. As part of the EIR prepared for the
Esperanza Specific Plan additional geologic and
soils information for the Specific Plan area will
be provided.

3.10Seismicity
The City of Ontario NMC Ontario Ranch
General Plan EIR identified numerous
earthquake faults within a 50-mile radius of the
Specific Plan area. Major mapped faults include,
but are not limited to, the Chino, Whittier and
North Elsinore, and Cucamonga Faults. For the
“maximum probable earthquake” (MPE), defined
as the 100-year event normally considered in the
design of noncritical structures, the values range
from about 0.13 to 0.20 g (i.e., the unit force
of gravity). In the design of certain critical or
important facilities such as hospitals and dams,
the “maximum credible earthquake” (MCE)
event is considered. For the three faults, the
MCE should yield an estimated peak horizontal
acceleration in the range of 0.33 to 0.52 g.

A zone of concentrated, relatively low-magnitude
seismicity extends to the southwest from the
San Jacinto fault zone (Rialto-Colton branch)
along what is referred to an “inferred fault near
Fontana.” Where the “inferred fault” (Fontana
trend) stops, this zone of micro-seismicity
continues in a southwesterly to westerly direction
terminating in the Sphere of Influence area. It
is expected that the MPE for this fault structure
could produce horizontal accelerations in the
range of 0.3 to 0.5g. More distant faults are
capable of larger earthquakes with a higher
probability of occurrence. The San Andreas fault
is expected to generate a MCE event every 150
to 200 years, yielding a peak horizontal ground
acceleration of approximately 0.21 to 0.26 g in
the NMC Ontario Ranch
.

In accordance with the “Uniform Building
Code” (UBC), the Esperanza Specific Plan area
is located within Seismic Zone No. 4. UBC
procedures have been designed to ensure that all
subsequent development occurs in a safe manner
relative to those known hazards. As part of the
EIR prepared for the Esperanza Specific Plan,
additional seismicity analysis will be prepared.

3.11Vegetation
The Specific Plan area has been extensively used
for agricultural operations including dairy use.

Those areas not in active agricultural production
are occupied by rural residential housing. The
natural vegetation and soils conditions that once
occurred throughout the Specific Plan area have
been significantly altered through agricultural
uses, leaving little or no native vegetation. As
part of the EIR prepared for the Esperanza
Specific Plan, additional vegetation analysis will
be prepared.

4.1Introduction
The Esperanza Specific Plan offers a variety of
residential housing types within a community
designed around a system of parks located
within easy walking distance from each
residential Planning Area. Pedestrian and bicycle
connectivity is provided through a system of
street separated walkways and on-street bicycle
trails linking each residential Planning Area and
connecting to parks located within Esperanza.

Residential development, comprised of
approximately 164.08 174.10 net acres, is
designed to address a variety of lifestyles, such
as singles, families, executives and “empty
nesters.” Single family detached housing types
will include conventional detached homes on lots
varying between 3,900 and 4,900 square feet in
size, homes designed in a 2-Pack configuration,
alley loaded cottage homes, and two types of
courtyard homes. Attached housing will include
row townhomes and motorcourt townhomes
designed around a common motorcourt.

Parks comprise approximately 9.89 net acres of
Esperanza and are distributed throughout the
community offering recreational opportunities
within close proximity to each residential
neighborhood.

The Land Use Plan shown in Exhibit 8, “Land
Use Plan” depicts the proposed land uses for
Esperanza. The “Land Use Summary,” Table 2,
provides a tabulation of land uses by acreage and
residential density.

4.2ResidentialUse
The Esperanza Specific Plan permits the
development of up to 1.594 1,652 residential
dwelling units providing single-family detached
homes and single family attached homes.

Residential land use areas are contained within
11 distinctive Planning Areas linked by a
network of street separated sidewalks and onstreet bicycle paths connecting all the Planning Areas to a centrally located park.

4.2.1 Variety of Housing Types
Esperanza provides a mix of housing types
to address a variety of lifestyle choices and
economic segments. Single family detached and
single family attached residential products, with
a variety of architectural styles, will be offered
within Esperanza. Altogether, a total of 1.594
1,652 residential dwelling units will be developed
at an overall average density of 7.657.41
dwelling units per gross acre.

4.2.1.1 Single Family Detached –
RD-1 (50’ wide lots)
The Esperanza Specific Plan allows for the
development of approximately 158 conventional
single-family detached dwelling units at an
average density of approximately 6.12 dwelling
units per net acre. The RD-1 neighborhoods
will be designed with access to homes from the
local street with an emphasis on architectural
orientation toward the street. Garage
configurations will include shallow recessed
garages, mid or deep recessed garages, split
garages, and tandem garages, to highlight the
home’s architecture and create a more attractive
streetscene. RD-1 homes are located within

RD-2 (55’ wide lots)
The Esperanza Specific Plan allows for the
development of approximately 107 conventional
single-family dwelling units at a density of
approximately 5.56 dwelling units per net acre.

The RD-2 neighborhood is designed with access
from the local street with garage configurations
which include recessed garages, mid or deep
recessed garages, split garages and tandem
garages to present an architecture forward
streetscene. RD-2 homes are planned within
Planning Area 8.

4.2.1.3 Single Family Detached –

Approximately 100 residential 2-Pack dwelling
units will be developed on approximately 14.62
acres at a density of 6.84 dwelling units per net
acre with a minimum lot size of 3,400 square
feet. By configuring the units in a 2 Pack design,
a larger usable sideyard area is provided for each
unit and garages can be either located to the rear
of the lot or set back from the front of the homes
at a distance, which preserves the streetscene for
home frontage. Residential housing in a 2 Pack
design is planned for Planning Area 10.

4.2.1.4 Single Family Detached –
RD-4 (Cottage Homes)
Esperanza will allow for approximately 243
single family detached cottage home residential
dwelling units developed on approximately 30.81
acres on lots of approximately 2,400 minimum
square feet at an average density of 7
.89 dwelling
units per net acre. This alley loaded residential
development will be designed to embrace the
street and maintain an architectural orientation
for the street. Cottage single family detached
residential dwelling units are proposed for
Planning Areas 2 and 6 within Esperanza.

4.2.1.5 Single Family Detached
or Attached – RD-5 and
RD-6 (Courtyard & RowTownhomes)
Two types of single family detached housing in
a courtyard design are proposed for Esperanza.

A total of 157 dwelling units will be developed
as RD-5 residential housing within a module
comprised of 4 residential units surrounding a
common motorcourt. RD-5 residential products
are proposed for 17.64 acres of Esperanza within
Planning Area 5 at a density of 8.90 dwelling
units per net acre. A total of 303 dwelling units
will be developed as RD-6 residential housing
within a module comprised of 6 residential
units surrounding a common motorcourt or
row townhomes. RD-6 residential products are
proposed for 19.92 acres of Esperanza within
Planning Areas 2 and 4 at a density of 16.72
dwelling units per net acre. Garages are accessed
from the motorcourt or alley, which allows for
the fronts of garages to be turned away from the
street or set back far enough from the street that
the residential architecture is the predominant
streetscene feature.

4.2.1.6 Single Family Attached –
RD-7 (Row Townhomes)
RD-7 residential product proposed for
Esperanza consists of 319 units of attached row
and motorcourt townhomes within Planning
Area 1, 156 units of attached row townhomes
to be developed on approximately 11.1 acres
at density of 14.05 dwelling units per net
acre within Planning Area 3 and 46 161 row
townhomes at approximately 16.07 dwelling
units per net acre in PA 11
. RD-7 residential
product is designed with alley access maintaining
an architectural streetscene.

4.2.1.7 Single Family Attached
– RD-8 (Motorcourt
Townhomes)
RD-8 residential product proposed for
Esperanza consists of 238 units of attached
townhomes designed around a common
motorcourt. RD-8 residential product will be
developed on approximately 19.42 acres at a
density of 13.76 dwelling units per net acre
within Planning Area 3.

4.2.2 Neighborhood Design
The community plan for Esperanza offers a
neighborhood design reminiscent of older
traditional Southern California neighborhoods.

The design features described below are
intended to create a strong identity and sense of
neighborhood for the residents of Esperanza.

A “modified grid” style of street design in
residential neighborhoods with sidewalks
separated by landscaped parkways provide visual
interest, slow traffic on each street by providing
alternate routes, and enhance a pedestrian
orientation for neighborhoods. Sidewalks
separated from streets by landscaped parkways
promote pedestrian mobility and encourage
opportunities for neighbors to meet and greet
each other along the street.

A human scale of architecture within Esperanza
will enhance the pedestrian friendly character of
the community. Architectural features such as
front porches, railings, enhanced entries, a mix of
materials and textures, and authentic detailing on
elements such as windows and doors, columns,
balconies, and lighting combine to create a
human scale of residential architecture.

Innovative garage designs will be utilized in
order to de-emphasize the visual impact of
garage doors on the streetscene. Such design
techniques will include shallow, mid, or deep
recessed garages , split-garages, turn-in garages,
tandem garages, garages located on rear alleys,
and garages located around a common courtyard
in order to de-emphasize their view from the
street
.

4.3Parks
Parks are provided throughout the Esperanza
Specific Plan area within easy walking distance
to any residential neighborhood. Exhibit 9,
“Master Plan of Parks,” illustrates the types and
locations of parks planned for Esperanza.

4.3.1 Neighborhood Park
An approximately 5.39 net acre centrally located
neighborhood park will be developed as part of
Esperanza. The neighborhood park will include
picnic areas, tot lots, trails, and open play fields.

4.3.2 Pocket Parks
An approximately .84 net acre park will be
provided for recreational use within Planning
Area 9. An approximately 1.29 net acre park
will be located within Planning Area 6, a one
acre park will be provided within Planning Area
5, and an approximately 1.39 net acre linear park
will be provided in Planning Area 10. Private
open space areas of approximately ½ acre in size
will be provided as part of the development of
Planning Areas 1, 3 and 4. The exact size and
locations of these private open space areas will
be determined as part of the final site design for
these neighborhoods.

4.4School Site
A 10.02 net acre site was originally reserved
within the Esperanza Specific Plan for the
development of an elementary school to serve the
K-5 school age needs of the Ontario community.

In the event the school site in Esperanza is not
purchased by the Mountain View School District
the 10.02 acre site may revert to a residential
zone for the development of an additional 46
161 row townhome residential dwelling units
pursuant to the provisions established in Section
7, “Implementation.”

ss
The infrastructure, utilities, and public services
to be provided as part of the development of the
Esperanza Specific Plan are discussed in this
section.

5.1Circulation
The circulation plan for Esperanza reinforces
the objectives of providing a traditional
neighborhood design. In addition to providing
safe and efficient movement of vehicular traffic
through the project, the Circulation Plan also
provides a safe environment for pedestrian
movement and bicycle traffic reducing the
reliance on the automobile as a means of travel.

In addition, transit stops and bus turnouts will
be provided as required by Omnitrans, along
the Master Plan streets, which are a part of the
Esperanza community. The “Master Circulation
Plan,” Exhibit 10 establishes the hierarchy and
general location of roadways within Esperanza.

The minimum design speeds to be used for
centerline curve radii, super elevation, corner
sight distance; vertical and horizontal alignment
and sight distance, etc. are listed below:

5.1.1 Master Planned
Roadways
The Esperanza Specific Plan is bounded on
the east, south, west, and is bisected by four
City of Ontario Master Plan roadways, which
will provide access to and from the Specific
Plan area. Additional rights of way may be
needed at critical intersections to accommodate
additional left and right turn lanes pursuant
to the recommendations of the traffic study
prepared for the Ontario Ranch. Hamner
Avenue bounds the Specific Plan area to the east
and is the county line between San Bernardino
and Riverside Counties; Bellegrave Avenue
bounds the Specific Plan area to the south and
is also the county line between San Bernardino
and Riverside Counties; Mill Creek Avenue
bounds the Specific Plan area to the west, and
Eucalyptus Avenue bisects the Specific Plan area
in an east/west direction.

Where the Specific Plan limits extend to the
centerline of any roadway, the development
project shall construct the full half-width street
improvement, plus a 14-foot travel lane with a
5-foot paved shoulder beyond the centerline.

If the roadway includes a raised median, the
project shall construct the full median, and the
additional 14-foot travel lane with a 5-foot paved
shoulder. The 14-foot travel lane is a minimum
that may be increased as necessary pursuant to
the requirements of the City Engineer.

5.1.1.1 Hamner Avenue
Hamner Avenue abuts the Specific Plan area
on the east. Hamner Avenue is a designated
Divided Arterial Parkway 1-1 roadway with a
total right-of-way of 148 feet. Hamner Avenue
will carry regional traffic to and from Esperanza
and will provide access to the specific plan area
along the eastern boundary of the specific plan
area. Exhibit 11, “Hamner Avenue” illustrates
the improvements for Hamner Avenue. The
developer of the Specific Plan area adjacent to
Hamner Avenue will be responsible for all on site
improvements for the westerly half of Hamner
Avenue as determined by the City Engineer and
pursuant to the mitigation measures identified
in the EIR and the Conditions of Approval
established on the approved tentative maps
for the project. Bus turnouts will be required
along Hamner Avenue to the satisfaction of the
City Engineering Department and Omnitrans.

Parking will be prohibited on Hamner Avenue.

Bellegrave Avenue, a Standard Arterial roadway,
abuts the Specific Plan area on the south and
carries regional east/west traffic to and from
Esperanza. Improvements to the south side
of Bellegrave Avenue currently exist. Exhibit
12, “Bellegrave Avenue” illustrates the halfstreet improvements for Bellegrave Avenue.

The developer will be responsible for all on
site improvements for the northerly half of
Bellegrave Avenue. Phasing of the improvements
will be determined by the City Engineer and
pursuant to the mitigation measures identified
in the EIR and the Conditions of Approval
established on the approved tentative maps for
the project. Bus turnouts will be required along
Bellegrave Avenue to the satisfaction of the City
and Omnitrans.

5.1.1.3 Mill Creek Avenue
Mill Creek Avenue abuts the Specific Plan area
on the west. Mill Creek Avenue is a designated
Collector Street with an ultimate right-ofway
of 88 feet, with 64 feet of paved area and a
12-foot parkway on each side of the street, to
include a 5-foot sidewalk separated from the
street by a 7-foot landscaped area. In addition
a landscaped buffer of 18 feet in width will be
provided between the back of the sidewalk and
the residential community wall. The rightofway improvements required to Mill Creek Avenue are illustrated in Exhibit 13, “Mill Creek
Avenue.” The developer(s) will be responsible
for the off site improvements as determined
by the City Engineer and pursuant to the
mitigation measures identified in the EIR and
the Conditions of Approval established on the
approved tentative maps for the project. Bus
turnouts will be required along Mill Creek
Avenue to the satisfaction of the City and
Omnitrans. Parking will be prohibited on Mill
Creek Avenue. Exhibit 13, “Mill Creek Avenue”
illustrates these improvements.

5.1.1.4 Eucalyptus Avenue
Eucalyptus Avenue bisects the Specific Plan
area and is designated as a Standard Arterial
roadway. Exhibit 14, “Eucalyptus Avenue”
illustrates the Eucalyptus Avenue full-street
improvements. The developer will be responsible
for all improvements to Eucalyptus Avenue.

The phasing of these improvements will be
determined by the City Engineer and pursuant
to the mitigation measures identified in the EIR
and the Conditions of Approval established on
the tentative maps for the project. Parking will
be prohibited on Eucalyptus Avenue.

5.1.2 Local Streets and Alleys
Within the Specific Plan area neighborhood
streets of varying design will provide access and
circulation through the community. Many of the
neighborhoods will be served by private alleys,
which are located in the rear of residences, in
order to maintain a traditional, “architecture
forward” streetscape for the community. Public
and private local streets within residential
areas are designed to distribute vehicular traffic
from the public arterial and collector streets
adjacent to the Specific Plan area into and
through residential neighborhoods. Local streets
and private alleys proposed for Esperanza are
illustrated on Exhibit 15, “A Street” – Primary
Local Street” Exhibit 16, “Local Streets and
Cul-De-Sac Sections;” Exhibit 17, “Private
Neighborhood Streets;” and Exhibit 18, “Private

5.1.2.2 Local Neighborhood Streets
and Cul-De-Sac Streets
A network of local public neighborhood streets
and cul-de-sac streets will provide internal
circulation throughout Esperanza for residents.

Exhibit 16, “Local Streets and Cul-de-sac
Sections” illustrates these street concepts.

5.1.2.3 Private Neighborhood
Streets
Private neighborhood streets will provide
internal circulation within single family attached
and single family courtyard product areas.

Water, recycled water, and sewer utilities may be
designated as “public utilities” if located within
public or private streets. All public utilities
within private streets shall be designed per
City standards and contained within acceptable
easements. The CC&Rs for the project shall
contain language requiring all work proposed
by the HOA within such easements to be plan
checked and inspected by the City, including
applicable fees. Generally, utilities will not be
accepted as public within alleys, parking areas
or driveways. The extent to which said utilities
will be accepted as public utilities shall be at the
full discretion of the City during final design
review. Private Neighborhood Streets planned for
Esperanza are illustrated in Exhibit 17, “Private
Neighborhood Streets.”

5.1.2.4 Private Alleys
Private alleys within the residential development
will have a minimum of 20 feet of paved area
with 5 feet of landscaping on each side. In
areas where fire access is required, the minimum
paved area will be 24 feet with 3 feet of
landscaping on each side. Alleys with “dead end”
conditions will be a maximum length of 150
feet. Parking is prohibited along alleys. Tapers
will be incorporated at the point where private
alleys intersect with public streets. The taper
width will be determined per the approval of
City of Ontario Fire Department, Engineering
Department and Planning Department.

5.1.2.5 Private Drive Aisles
Private drive aisles are planned with a total paved
width of 24 feet and an 18 foot deep parking area
on each side.

Water, recycled water, and sewer utilities may be
designated as “public utilities” if located within
public or private streets. All public utilities
within private streets shall be designed per
City standards and contained within acceptable
easements. The CC&Rs for the project shall
contain language requiring all work proposed
by the HOA within such easements to be plan
checked and inspected by the City, including
applicable fees. Generally, utilities will not be

5.1.3 Traffic Calming
The Esperanza Specific Plan includes design
features within residential neighborhoods to
encourage drivers to proceed slowly and reduce
traffic noise on streets contributing to safe and
livable neighborhoods in which to walk, bike,
and drive.

Traffic calming within the Esperanza Specific
Plan is designed to address the following goals:
• Reduction in traffic speeds.
• Reduction in traffic related noise.
• A safe and pedestrian friendly circulation
system to encourage walking.

The following design features will be
implemented in the roadways within Esperanza.

Local Neighborhood Street Design
Neighborhood streets within Esperanza are
designed in a “modified grid” with landscaping
on either side within parkways to add interest
in the street encouraging drivers to slow their
travel speed and observe their surroundings.

Incorporating tapered intersections for
local streets as illustrated in Exhibit 19,
“Neighborhood Street Tapers,” may reduce traffic
speeds on local residential streets.

Alleys Tapers
Private alleys within Esperanza will consist of
20-24 feet of paved travel area with 3-5 feet
of landscaping on each side. Speeds for traffic
entering the alleys and cut through traffic can be
reduced by incorporating tapers at the entrance
to these alleys as illustrated on Exhibit 20, “Alley
Tapers.”
Landscaping
Landscaping adjacent to streets within the
Specific Plan area will combine the use of shade
trees, shrubs, and groundcover adjacent to
sidewalks to create a more intimate streetscape
encouraging drivers to reduce driving speeds.

The landscape concept for Esperanza is designed
to contribute to a sense of the street system as
a pedestrian protected area to promote slower
traffic speeds.

Roundabouts
A roundabout will be incorporated into the street
design at the intersection of two local streets as
illustrated in Exhibit 10, “Master Circulation
Plan.” The use of a roundabout rather than a
conventional all-way stop at this intersection will
maintain traffic flow by requiring traffic entering
the roundabout to yield to traffic traveling within
the roundabout. The lack of a stop sign allows
entering traffic to merge with the flow of traffic.

5.1.4 Pedestrian Circulation
Off-street pedestrian circulation will be
available throughout Esperanza by means of
the interconnected, paved sidewalk system
within the roadway right-of-way, separated from
vehicular travel lanes by a landscaped parkway.

The Esperanza pedestrian system provides
connectivity among residential neighborhoods to
the Neighborhood Park and pocket parks within
the Specific Plan area.

5.1.5 Bicycle Trails
Bicycle trails are an integral element to creating
accessibility and mobility within Esperanza. A
Class 1 bike trail will be provided within the
parkway on the north side of Eucalyptus Avenue
and an on-street bike trail will be provided on
both sides of Eucalyptus Avenue connecting to
on-street bike trails provided on local residential
streets within the Specific Plan to connect all
residential neighborhoods to one another, and
to the Neighborhood Park located towards the
center of the Specific Plan boundary.

Class II on-street striped bike lanes shall be
provided on roadways within the Esperanza
Specific Plan area as determined by City
Engineer.

The Master Plan for pedestrian and bicycle
circulation for Esperanza is illustrated on Exhibit
21, “Pedestrian and Bicycle Circulation Plan.”
Private Drive Aisle
Private Alley

Notes:

1. Final Alley Design is subject to approval by the City Engineer, Fire Department and Planning Department.

2. All public utilities within private streets shall be designed per City standards and contained within acceptable easements. The extent to which said utilities will be accepted as public utilities shall be determined at the full discretion of the City during final design review.

5.2Domestic andRecycled
Water
MasterPlan
Domestic water will be provided by the City
of Ontario. The Ontario Ranch Water Master
Plan Phase 1 (Phases 1a–1d) identifies new
water facilities to include one reservoir, three
groundwater wells and potable and reclaimed
transmission water lines. Construction of the
on site and off site Master Plan water service
improvements shall be the responsibility of the
developer(s) and is required prior to issuance
of building permits for Esperanza. Two of the
waterlines included in the Phase 1 improvements
are a 24 inch water line in Hamner Avenue,
adjacent to the site on the east, and a 24-inch
water main in Eucalyptus Avenue, which goes
through the center of the project.

5.2.1 Domestic Water
The project lies within the 925 Zone. New
domestic water mains to be constructed as part
of the development of Esperanza will include a
12-inch Master Plan water main in Mill Creek
Avenue, from the northerly boundary of the
Specific Plan to Eucalyptus Avenue. Within the
Specific Plan area, a network of 8-inch and 12’
inch water lines will be installed. The On Site
water system will include connections to two
different transmission mains.

The City is in the process of updating the Water
Master Plan. Any changes resulting from the
updated Master Plan will be incorporated into
the Esperanza Water Master Plan.

There are two groundwater wells located
adjacent to Bellegrave Avenue to the north.

These wells and water transmission lines in
Bellegrave Avenue, are owned and operated by
the Chino Basin Desalter Authority (CDA).

As part of the development of the Specific
Plan area, improvements shall be made, to the
satisfaction of the CDA and the City of Ontario,
surrounding the two existing well sites located
at the north side of the ultimate right of way
of Bellegrave Avenue. Improvements shall
include, but are not limited to, perimeter fencing,
relocation of existing utilities within the ultimate
right of way, street landscaping within the
right of way fronting the project, and driveway
approaches. The Master Plan for domestic
water for Esperanza is illustrated on Exhibit
22, “Conceptual Domestic Water Master Plan.”
The conceptual on site domestic water system
is illustrated on Exhibit 23 “On Site Domestic
Water Plan.”

5.2.2 Recycled Water System
The Inland Empire Utilities Agency (IEUA)
will ultimately provide recycled water from
IEUA’s RP-1 and RP-1 outfall parallel located in
Carpenter Avenue via City of Ontario recycled
water mains as presented in the Water Master
Plan for the Ontario Ranch. The Specific
Plan area is located within the 930 Zone. The
construction phase source of recycled water to
serve the Specific Plan area will be conveyed
to the 930 Zone from the 1050 Zone via a
Master Plan pressure reducing station located
in Archibald Avenue north of Chino Avenue.

The master planned recycled water mains to
be constructed as part of the development of
Esperanza will include the following:

Within the Specific Plan area, 8-inch recycled
water mains are proposed to serve the
development. The City’s goal is to maximize the
use of recycled water including but not limited
to irrigation of parks, schools, street landscaping,
recreation trails, common area residential
landscaping and commercial/industrial
landscaping edges. The parks and landscaped
areas that will be irrigated with recycled water
and the calculated recycled water demand are
contained in the report titled, “Esperanza Water
and Recycled Water Hydraulic Analysis.” An
Engineer’s Report approved by the City and the
Department of Health is required prior to the
use of recycled water.

The conceptual Master Plan for recycled
water for Esperanza is illustrated on Exhibit
24, “Conceptual Recycled Water Plan.” The
conceptual on site recycled water system is
illustrated on Exhibit 25, “Conceptual On Site
Recycled Water System.”

5.3SewerMasterPlan
Sewer service for Esperanza will be provided by
the City of Ontario. The City’s Sewer Master
Plan identifies ultimate sewer facilities from
the Specific Plan area to the Eastern Trunk
Sewer. These Master Planned facilities include a
15inch sewer main extending from the northerly
boundary of the Specific Plan area, along Mill
Creek Avenue increasing to a 21-inch sewer
main at Eucalyptus Avenue and a 24-inch
sewer main along Bellegrave Avenue westerly
to the Master Planned Eastern Trunk Sewer.

Completion of these Master Plan improvements
is required to provide the ultimate sewer service
to Esperanza. Within the Specific Plan area
a network of 8-inch and 15-inch sewer lines
will be installed. The sizing and alignment of
all off site sewer improvements necessary for
mitigation of impacts shall follow the results of
the approved Sanitary Sewer Technical Study.

The Conceptual Sewer Master Plan for
Esperanza is illustrated on Exhibit 26, “Sewer
Master Plan.” The conceptual on site sewer lines
are illustrated on Exhibit 27, “Conceptual On
Site Sewer.”

5.4Drainage
The City’s Storm Drain Master Plan identifies
new storm drain facilities to serve the Specific
Plan area extending northerly from the County
Line Channel within Mill Creek Avenue.

Completion of these Master Plan improvements
will provide permanent storm drain service to
Esperanza.

That portion of the Master Planned line, which
lies within Esperanza, will be constructed as a
part of the development of the project. These
improvements include a 90-inch storm drain in
Mill Creek Avenue transitioning to a 102inch
storm drain, connecting to the County Line
Channel.

On site storm drains will be constructed
to convey the on site flows to the proposed
Master Planned storm drain line in Mill Creek
Avenue. The locations and size of on site storm
drains within Esperanza will be established in
accordance with City requirements as part of the
approval by the City of Ontario of tentative tract
maps for the Esperanza Specific Plan area.

The Drainage Master Plan for Esperanza is
illustrated in Exhibit 28, “Storm Drain Master
Plan.” The size and location of the proposed
storm drain may change based on the final
design
.

5.4.1 NPDES Compliance
The grading and drainage of the Esperanza
Specific Plan area shall be designed to detain,
filter and treat surface runoff, in a manner and
combination which is practical, to comply
with the most recent requirements of the San
Bernardino County NPDES Storm Water
Program’s Quality Management (WQMP) for
significant new development projects. The
objective of the WQMP for this project is to
minimize the detrimental effects of urbanization
on the beneficial uses of receiving waters,
including effects caused by increased pollutants
and changes in hydrology. These effects may
be minimized through the implementation of
site designs that reduce runoff and pollutant
transport by minimizing impervious surfaces and
maximizing on-site infiltration, Source Control
Best Management Practices (BMP’s) and/or
either on-site Structural Treatment Control
BMP’s, or participation in regional or watershedbased Treatment Control BMP’s.

Prior to the issuance of a grading or construction
permit, a Storm Water Pollution Prevention Plan
(SWPPP) will also be prepared. The SWPPP
will be prepared to comply with the California
State Water Resources Control Board’s (State
Water Board) current, “General Permit to
Discharge Storm Water Associated With
Construction Activity” and the current Area
Wide Urban Storm Water Runoff (Regional
NPDES Permit). The SWPPP will identify and
detail all appropriate Best Management Practices
(BMP’s) to be implemented or installed during
construction of the project.

In addition to the preparation of a SWPPP for
construction-related activities, and as part of
the approval of any grading plans within the
Specific Plan Area, the applicant will be required
to submit a Water Quality Management Plan
(WQMP) on the regional model form provided
by the City. The WQMP shall identify and
detail all Site Design BMP’s, Source Control
BMP’s and Treatment Control BMP’s to be
implemented or installed at this site in order to
reduce storm water pollutants and site runoff.

An off site regional stormwater runoff
treatment facility with capacity to accept and
treat drainage from portions of the Specific
Plan Area has been constructed. This regional
treatment facility will be part of an overall
solution for storm water treatment within
this planned development area. Projects with
reserved treatment capacity allocations sin the
regional facility will utilize this off-site facility
as their primary BMP for addressing urban
runoff water quality and hydro-modification
impacts, in their respective WQMPs. If a project
cannot obtain treatment capacity in the regional
stormwater treatment facility, alternative on-site
or off-site Low Impact Design BMBs will be
required based on the must current MS4 Permit
requirements.

5.5Schools
The Mountain View School District is the
school district serving the K-8 school needs
of Esperanza. The Chaffey Joint Union High
School District serves the 9-12 school age needs
of the Specific Plan area. Additional elementary,
middle, and high schools are needed to serve the
needs of school age children within the Ontario
Ranch. An elementary school site has been
proposed within the Esperanza Specific Plan
and a middle school site has been proposed in
Planning Subarea 24. Colony High School is
located at the southwest intersection of Mill
Creek Avenue and Riverside Drive and a future
high school has been proposed in Planning
Subarea 23. Development of the Esperanza
Specific Plan area will generate an estimated
student population as follows (based on student
generation numbers supplied by the City of
Ontario, “School Generation for Ontario Ranch
Subareas,” July 2, 2004. The developer(s) of
Esperanza will be required to pay school fees as
required by State of California.

5.6PublicUtilities

5.6.1 Natural Gas
The Gas Company will provide natural gas to the
Specific Plan area. Gas mains will be installed
to the Specific Plan area by the Gas Company as
necessary.

5.6.2 Electricity
Southern California Edison will provide
electricity to the Specific Plan area from existing
facilities in the vicinity of the Specific Plan
area. Proposed new facilities to serve the project
will be owned and operated by the City of
Ontario and located underground. Existing lines
within the Specific Plan area shall be placed
underground by developer and according to the
City of Ontario adopted ordinance.

5.6.3 Telecommunications
The City of Ontario will be providing
OntarioNet, fiber-to-the-home. OntarioNet is a

providing advanced Internet/data services to all
homes and businesses within the Ontario Ranch.

OntarioNet will provide community related
services including: traffic management; on-line
civic services; meter reading; educational services;
and a variety of other community services. Based
on the demographics of the Ontario Ranch and
the traffic issues into Orange and Los Angeles
Counties, the demand for telecommuting in the
Ontario Ranch is anticipated to be significant.

OntarioNet and the high-speed data services it
provides will allow residents of the Esperanza
Specific Plan to effectively telecommute to
their jobs and in general provide a significant
economic benefit to Ontario. Verizon currently
provides telephone service within the Specific
Plan area and can provide telecommunication
service if they choose to do so.

including Organics.

5.7GradingConcept
The site falls at an average slope of approximately
two percent (2%). The Grading Concept
for Esperanza is to work with the existing
topography to maintain natural grade and
elevations wherever possible. The grading
operation for the Specific Plan area will generally
consist of the removal of any manure remaining
from dairy operations, clearing and grubbing,
demolition of existing structures, and moving
of surface soils to construct building pads and
streets. Additionally, where slope conditions are
present, the property shall be located at the top
of the slope. In areas adjacent to a ridgeline
or in moderate slope areas, dwelling units and
structures should be sited to: • Use the natural ridgeline as a backdrop for structures;
• Use landscape plant materials as a backdrop;
and
• Use structure to maximize concealment of cut
slope.

If retaining walls are required, the following
criteria shall be used: • Exposed walls and fences facing roadways shall be no greater than 3-feet retaining (9-
foot total wall) in height, except as necessary
for acoustical purposes to satisfy the intent of
the noise ordinance.
• Where retaining walls or fences face
roadways, they shall be built, when feasible, of
decorative materials consistent with the wall
theme of the neighborhood.

The Conceptual Grading Plan, as illustrated in
Exhibit 29, “Conceptual Grading Plan,” will
provide for a balance of cut/fills for the site
Grading plans for each tract in the Specific Plan
area will be reviewed and approved by the City
of Ontario Building, Planning, and Engineering
Departments prior to the issuance of grading
permits. All grading plans and activities will
conform to the City grading ordinance and dust
and erosion control requirements.

6. Transfer of Dwelling Units -The Esperanza Specific Plan allocates a total number of units to each Planning Area as indicated in
the “Land Use Summary” Table 2, Section
4, of the Esperanza Specific Plan. Variations
in the number and type of dwelling units
within each residential Planning Area may
occur at the time of final design of the
neighborhood depending upon the residential
product identified for development. Changes
in allocation of residential units, up to a
maximum of fifteen percent (15%), are
permitted among the residential planning
areas within the Esperanza Specific Plan,
subject to approval by the City and upon
agreement of each respective property owner/
developer, provided the total number of units
established for the Esperanza Specific Plan
area is not exceeded.

7. Best Management Practices – Development
of storm water runoff improvements, within
the Esperanza Specific Plan, shall adhere
to currently adopted Best Management
Practices (BMP’s). The Site Design BMP’s
may include but not be limited to creating
landscape strips and landscaped setback areas
that can be swaled and depressed to retain
and infiltrate irrigation water and runoff
from smaller storm events, drain rooftops
into rain gutters which would drain into an
area of porous subgrade, and depressing the
park areas to provide storm water infiltration
and water quality treatment. Common area
landscaping and parks shall be designed to
function as a series of shallow storm water
treatment basins and infiltration zones for
storm water runoff from surrounding areas
wherever moderately well draining soils exist.

Currently the City of Ontario is considering
construction of a regional storm water runoff
treatment facility for the sub-watershed area
that this project lies within. If the treatment
facility is constructed, it may satisfy the
requirement for on-site treatment control
BMP’s for the Esperanza project.

8. Maximum Number of Dwelling Units - The
maximum number of residential dwelling
units permitted within the Esperanza Specific
Plan is 1,594 1,491 unless the 10.02 acre
elementary school site is not purchased by the

8.1Introduction
On a sunny morning in the fall of 1882, George
Chaffey stands on a mesa between the floodwater
washes of Cucamonga Canyon to the east and
San Antonio Canyon on the west, gazing at the
country directly in front of him lying at the foot
of snow-capped Old Baldy, beneath the Sierra
Madre Mountain Range. Having little capital,
George would rely on his powers of leadership
and vision and, at that moment, would throw
his heart and soul into the new colonizing
movement sweeping Southern California. With
help of his brother William and surveyor J. C.

Dunlap, he would purchase 6,218 acres and
design what would become the “City of Ontario,”
named after his former home in Ontario,
Canada. His vision of a model colony featured
the first reclamation irrigation system, abundant
electricity power and a beautiful parkway that
captured the imagination and interest of people
throughout the world. His vision was one of
hope for a great community. “Esperanza,” which
means “hope” in Spanish and accurately describes
the original vision intended for the “new”
Ontario.

Ontario is a thriving city today, although the
orchards and packing houses have since given
way to new landmarks such as Ontario Mills,
Ontario Convention Center and Ontario
International Airport. Hundreds of new
businesses have discovered that Ontario is “The
Gateway” to Southern California, conveniently
located 35 miles east of Los Angeles, and easily
accessible to I-10, I-15 and I-60 freeways.

Ontario spans nearly 28,000 square miles,
with a population of over 168,000, and is one
of Southern California’s fastest growing cities.

Ontario’s sun-belt mild weather and 312 days
of sunshine, allows you to enjoy the many
parks as well as the nearby mountains, beaches,
and deserts. The world-class Empire Lakes
Golf Course, designed by Arnold Palmer, will
challenge the avid golfer. The wine aficionados
will love sampling California’s finest at Galleano
Winery, Joseph Filippi Winery, and Vineyards.

8.2Design Guidelines for
Architectura
lCharacter
Architectural design should provide for high
quality neighborhoods. • Residential project design should consider the total context of the site with the incorporation
of appropriate scale and proportions of
building massing and details.
• The use of transitional spaces between
common and private areas such as entry
courtyards, private patios, low walls, and
porches is encouraged.
• The variation of both front and rear building
setbacks should be implemented to create
visual variety.
• The variation of garage placement on adjacent
lots is encouraged to provide a more diverse
street scene.
• Residential structures should be varied in
massing and articulation to provide visual
interest.
971
Section 8.

Design GGuiddelines Section 8. Design GGuiddelines

8.2 8.3
Neighborhoods should be sustained over time. • Architectural design themes should reflect historic Southern California styles.
• The use of natural indigenous building
materials and colors is encouraged.
• Structures should incorporate genuine
architectural details and decorative features.
• Architectural design should relate to human
scale.
• The location of doors and windows should
consider indoor/outdoor relationships to
create intimate and secure spaces.
• Architectural designs should create a cohesive
community without dominating the overall
street scene.

Building design should be sensitive to climatic
conditions and context. • Building elevations should consider sun orientation by including shaded and sheltered
areas.
• Variation of architectural designs should
include methods of protection from inclement
weather.
• Residential structures should be compatible
with, and responsive to, the environmental
setting.
• Building designs should incorporate spaces
that encourage outdoor use to take advantage
of temperate climatic conditions.

Architectural design should incorporate
materials and techniques that are cost effective. • The use of building materials should reflect the implementation of efficient construction
methods.
• Building elevations should include compatible
window and doors sizes that create a
consistent design theme.
• Construction techniques should incorporate
the use of standard components and
dimensions.

Varied floor plans and elevations in single-family
detached residential architectural packages
should be incorporated as follows:

Reverse elevations and floor plans are considered
as a separate elevation and floor plan. Reverse
floor plans and elevations are considered as a
separate floor plan and/or elevation for purposes
of implementing the table below.

Diversity is a fundamental guiding principle at
Esperanza. This ensures that neighborhoods are
varied and that blanket uniformity is avoided.

Builders are required to produce a minimum of
two styles for a 3-plan design program, and three
styles for a 4-plan or more design program.

8.3ArchitecturalContext
The original model colony of Ontario has a
rich agricultural legacy of farming including
citrus orchards, grape vineyards and alfalfa
fields. Typical of Southern California farming
communities, Ontario has a variety of traditional
architectural styles. Western European and
East Coast architectural details and forms
were incorporated into the farm houses and
local styles evolved from Country French
and Tuscan styles and new interpretations of
Monterey, Traditional, Craftsman and Ranch
styles were erected. Architectural styles,
elements and massing were reinvented utilizing
available indigenous building materials. Plan
designs and elements such as window sizes
and proportions were modified to address local
climatic conditions which were warmer and drier.

Materials were plaster, stucco and siding with
brick, stone or other masonry accent materials.

The sunny Southern California climate allowed
year round use of outdoor spaces and inspired
covered porches and balconies.

Southern California was also influenced by
Spanish architectural styles brought to the region
by Spanish settlers and missionaries. These
homes were well suited for the temperate climate
of Southern California. The architectural theme
for Esperanza is based upon these historical
styles found in Ontario and the architectural
styles have been selected in order to be reflective
of older neighborhoods of historic Ontario.

Each architectural style outlined in these
guidelines should be detailed with elements
that represent the authentic character of that
particular style.

Together the styles should be designed to create
a neighborhood character that will be sustainable
over time. Each home should contribute to the
architectural character of the neighborhood.

Design elements such as porches, recessed
windows, architectural details and accents,
alternate garage configurations / orientations,
covered balconies, and articulated elevations are
encouraged to enhance individual homes and to
promote the overall neighborhood character.

8.3.1 Residential Design
Objectives
• Interpret architectural styles that are authentic
and reflect the historical character of the
region.
• Emphasize styles of architecture that are
compatible, yet vary enough to create interest
and diversity.
• Create visually interesting neighborhood
streets by varying elevation and floor plan
plotting.
• Utilize authentic materials and colors that
reinforce the overall design theme.
• Emphasize front elevations that relate
strongly to the street and contribute to the
livability of that realm.
• Provide alternative garage configurations.

The Esperanza Design Guidelines are to be
used as a tool to ensure the character and design
quality anticipated for the Community. The
Guidelines express objectives and approaches
rather than formulas and standards, allowing
certain architectural creativity and flexibility. The
images and sketches illustrated in the Guidelines
are intended to be conceptual in nature and are
to be used as general visual aids in understanding
the basic architectural design intent of
Esperanza. They are not meant to depict specific
floor plans or architectural elevations.

These Guidelines are organized into the
following sections: • Architectural Styles • Massing Principles • Materials & Detailing • Home Types • Landscape Design

8.3.2 Architectural Styles
The architectural character within each
neighborhood shall consist of complementary
traditional architectural styles. The materials and
colors of these home styles shall complement the
overall neighborhood design.

Architectural styles within each neighborhood
and product area within each neighborhood
should be compatible with one another and
blend with the character of each neighborhood.

Within cluster court style residential products,
a consistent architectural style shall be used
throughout the individual cluster.

Acceptable architectural styles within Esperanza
include: • Country French • Tuscany • Monterey • Spanish Colonial • Craftsman • Traditional • Western Ranch The styles selected share similar design attributes
and have been selected in response to the
following considerations: • They have a historic relevance to the region. • They are compatible and complementary. • They can be interpreted in a variety of ways. • They are generally accepted by the market. • They can be constructed using current building materials and methods.

Note: Additional styles proposed by the homebuilder
must be submitted to, and approved by, the City
of Ontario. Builders may submit home designs
using alternative architectural styles that
meet the design objectives of the specific plan,
provided they are appropriate to the region and
compatible with the character of Esperanza.

8.3.2.1 Country French
History and Character:

French Country architectural style is based
upon early American interpretations of French
Medieval architecture that made their way across
the United States from the Mississippi regions
around the turn of the century. Usually taking
the form of larger manor homes and estates,
this architectural style was adapted to fit smaller
rural homes. The French Country style conveys a
romantic and picturesque architecture. American
interpretations include houses with simple forms
with steeply-pitched roofs.

Massing: • Simple massing with asymmetrical forms and
gable roofs.

General Materials: • Stucco finished walls. • Deep recessed accents. • Vertical windows. • Simple detailing. • Stucco or masonry chimneys. • Decorative chimney caps. • Carriage garage doors or roll-up doors with a variety of panel patterns to reflect

8.4MassingPrinciples
This section provides suggestions for creating
neighborhoods and street scenes that have a
variety of building forms that are proportionate
to a human-scale and inviting to the pedestrian.

General Elements:

The general elements of building massing
include: • Front Articulation. • Rear Articulation. • Garage Placement. • Roof Form. • Balconies and Projections. • Building Offsets/Variable Setbacks.

Objectives: • Incorporate single-story elements. • Avoid large flat two-story walls. • Minimize two-story dominance on street scene, sidewalks and open spaces.
• Vary building setbacks along the street. • Minimize visual impact of garages.

8.4.1 Front Articulation
Intent:

The front elevation of the home is an important
element in creating a quality community at
Esperanza. Close attention will be placed on the
elevations and how they address the streetscene.

Emphasis on location and entry designs, living
areas and garages will provide a special street
appeal. Emphasis on a variety of building
massing will create a diverse street scene.

Guidelines: • Building massing should reflect the
architectural style.
• Massing elements should project enough to
avoid elevations that appear to be “tacked on.”
• Building details such as doors and windows
should be in proportion to the overall
massing.
• Building form is encouraged to reflect the
interior uses of the home.
• Front elevations for two-story homes should
incorporate a single-story element.
• Recessed two-story elements should create
human-scale buildings.
• All homes should have at least two plane
variations (excluding the garage) in front
elevation massing.

8.4.2 Rear Articulation
Intent:

Special attention shall be given to the design of
those dwellings adjacent to, or in close proximity
of, major community roadways, common
areas, open spaces, or entry features. Whether
viewed from distant or close range, massing
requirements will be implemented to ensure
positive community character in these conditions.

Generally, repetitious elements such as similar
building profiles and continuous gable ends are
to be avoided.

Guidelines: • Architectural massing and articulation should be consistent with the style of the home.
• Plans shall incorporate projections and/or
offsets that extend from the main wall lane.
• Vertical and horizontal plane breaks are
encouraged.
• Homes directly adjacent to arterial roadways,
collector roads, entry drives, common
areas, and open spaces should be given
particular attention in their rear articulation,
contributing positively to these edges.

8.5GaragePlacement
Intent:

The configuration, location and orientation of the
garage on the lot are integral design elements,
both for the composition of the home and its
contribution to the streetscene. Deemphasizing
the garage is important in order to maintain
the overall community design. Emphasizing the
living areas of the home as they address the street
will achieve this goal.

Placing living areas forward promotes social
interaction and facilitates ‘eyes on the street’ for
neighborhood security, while at the same time
establishing neighborhood orientation to the
pedestrian instead of the automobile.

Guidelines: • Garage door patterns should vary among
elevation types and reinforce the architectural
theme of the home.
• Standard 3-car garage configurations are
discouraged.

8.5.1 Garage Treatments
The home and the yard rather than the garage
must be the primary emphasis of the elevation as
seen from the street. Each plan shall incorporate
one of the garage design techniques listed below
and each parcel shall include at least two of these
techniques to reduce the emphasis on the garage;
and therefore, enhance the variable massing of
the streetscene.

8.5.1.1 Shallow Recessed Garages
Setting the garage back a minimum of three feet
in relationship to the front of the house/ or porch
is intended to reduce the overall visual mass of
the garage. The number of homes with shallow
recess garage configurations shall be limited to
25% of the total number of units in each builder
package.

8.5.1.2 Mid or Deep Recessed
Garages
Setting the garage back to the middle or rear
of the lot. This design treatment is intended to
expose more living space areas toward the street,
further reducing the visual impact of the garage
along the street.

8.5.1.3 Alley Loaded
The use of the alleyways locates garages off a
main loop road and creates a more traditional
streetscene, with the fronts of the houses facing
the street.

8.5.1.4 Split Garage
This treatment de-emphasizes the garage by
reducing the length of the continuous door.

Typically a one car garage and a one or two car
garage are split to provide a variation in the
appearance of the home. The single car garage
elements in this split condition may option into
living space that further enhances the streetscene
by replacing the garage door with windows.

8.5.1.5 Tandem Garage
This garage layout de-emphasizes the third
garage by concealing it behind a standard twocar garage condition. The tandem space is located so that it may option into living space. The two
car garage is typically either shallow or deeply
recessed into the lot and incorporated into the
architecture of the home.

8.5.1.6 Setbacks
A varied setback is encouraged along the street
frontage. Refrain from strict compliance to the
minimum garage setback so as not to contribute
to a repetitious and monotonous appearance
along the street.

Where garages are adjacent to one another at
common property lines, a two-foot minimum
difference in setbacks shall occur.

8.6Accessory Structures
Intent:

Accessory structures should be designed to
reinforce the architectural style of the primary
residence.

Guidelines: • Detached structures, such as casitas, pool cabanas and guest quarters associated with the single-family lot shall be designed to
match the style, detail, roof material/pitch and
massing criteria of the primary home.
• Detached garages, storage buildings and
outdoor sheds should incorporate design
features, materials and colors compatible with
the primary home.

8.7RoofForm/Pitch
Intent: • Roof form is another important design
element as it relates to the character of the
community, observed from both the external
edges and inside the neighborhood.
• Variety of roof form along streets creates a
positive visual edge.
• Appropriate massing of roof forms helps to
create human scale architecture to the street.

Guidelines: • Roof forms/pitch should reinforce the
architectural style of the homes.
• Roofs shall be composed of a series of simple
roof forms.
• Primary roof forms should be gable or hip
designs.
• Roofs shall vary in massing along street scene
and open spaces.
• Changes in the primary roof (ridge)
orientation are encouraged.
• Flat roof elements should be minimized
and incorporated only if appropriate to the
architectural style.

8.8BalconiesAnd
Projection
s
Intent:

As part of the overall design of a two-story
dwelling, balconies and projections provide
relief and interest at the second story. Balcony
projections shall be consistent with the
architectural character of the home. Additionally,
these elements create ideal outdoor spaces.

8.9BuildingOffsets/
Variab
le Setbacks
Intent:

Quality neighborhood design orients the
‘living’ areas of the home towards the street. To
encourage this orientation, alternative setbacks
are allowed for living areas as measured from the
back of walk.

The development standards for each planning
area/home type including building setbacks
are established by the Esperanza Specific Plan.

Additionally, building offsets or variable setbacks
for both living and garages are encouraged to
create variety in street scenes.

Guidelines: • Setbacks shall be appropriate and
proportionate to the housing type and lot size.
• Front setback should be varied along the
street. A front offset of a minimum of two
feet (2’) is encouraged between the front walls
of adjacent homes.
• Edge conditions such as homes backing to
collector roads and back-to-back homes
should incorporate variable rear setbacks to
create variety.

8.10Materials andDetails
Architectural materials and detailing are central
elements to creating quality communities.

Appropriate focus should be given to the
architectural details and the design of the details
and architectural elements of the home.

General Elements:

The general elements comprising the materials
and details of a building are: • Wall Materials/Finishes. • Doors and Windows. • Roofing Materials and Slope. • Fascias, Eaves and Rakes. • Accent Materials. • Exterior Colors.

inside corner or extend to the location of the
lateral fence.
• Masonry elements and accents should reflect
building forms and not appear as an applied
veneer.
• Footings shall be exposed no higher than six
inches (6”) above finished grade.

8.10.2 Accent Materials
Accent materials promote individuality in each
home and ensure diverse character within the
neighborhood. Accents can be used to reinforce
the architectural theme of the home.

Guidelines: • Accent materials should complement the overall color and style of the home. • Accent materials shall terminate at inside corners and be wrapped to coincide with an
architectural element.
• Accent materials may terminate at location of
the lateral fence or at logical end.
• Architectural trim applied to all elevations
should be consistent with front elevation of
the home.

8.10.3 Doors and Windows
The design and detail of the doors and windows
on a home reinforce the architectural style and
are key elements in the composition of the
exterior elevation of the home.
981

recesses are encouraged in keeping with the
architectural style.

8.10.4 Roofing Materials and
Details
Roofing materials as well as roof forms, pitch and
design details are integral elements that reinforce
the intended architectural style of the home.

Proposed roofs should be reflective of the
architectural style of the home.

Attention should be given to address the context
of the roof of each home relative to the adjacent
homes along the street.

Approved Roofing Materials:
(Subject to compatibility with the intended
architectural style) • Concrete tile (flat or curved profile) • Clay tile • Slate • High profile composition shingle (3-Dimensional)

Land
scapeArchitectural
Character
Careful consideration has been given to the
design of the community landscape architectural
character for the Ontario Esperanza Specific
Plan. The following design guidelines are
organized to help define the basic landscape
design principles for the Ontario Esperanza
Specific Plan. Observing these guidelines will
help to assure the “design vision” and integrity of
this planned community.

All landscape plans, streetscape plans, and
graphic designs with regard to community
identity, neighborhood identity, or entry
monumentation shall conform to the guidelines
as set forth herein, and shall be subject to review
and approval by the City of Ontario.

The “Conceptual Landscape Master Plan,”
Exhibit 30 on the next page shows the perimeter
streetscape design, Community entries and
monumentation, neighborhood park and
mini parks, pedestrian greenbelts, and general
landscape features of the Ontario Esperanza
Specific Plan area.

8.12.1 Perimeter Streetscape
Design
Streetscape design guidelines establish a
hierarchy for the landscape development along
the surrounding roadways, as well as establishing
a framework for consistency of design. Three

8.12.5 Interior Streetscape Design
Streetscape design within the interior of the
Ontario Esperanza Specific Plan community
shall be consistent in character with the
perimeter streetscapes and should help to
promote pedestrian circulation into the
“Community Core.”
Where interior streetscapes interface with
neighborhood/mini parks and open space, special
consideration should be taken to integrate
pedestrian circulation into these areas via a
streetside pedestrian system that links city
sidewalks to active walking trails and open space
uses. This is especially important within the
multi-family/high density residential planning
areas.

Two interior roadways bring residents into the
“Community Core,” Eucalyptus Avenue, running
East/West, and “Street A” that intersects with
Eucalyptus Avenue, running North/South.

8.13 City of Ontario
“Gateway” Monument
At the corner of Hamner Avenue and Bellegrave
Avenue, a city “Gateway” monument will be
located. Special consideration should be made
to integrate the perimeter landscaping along
Hamner and Bellegrave Avenue into the final
monument design and landscape character. The
City of Ontario is currently developing the
“Gateway” monument program for the Ontario
Ranch. Additional coordination with the City of
Ontario will be needed prior to developing this
area.

8.14 Entries and
Monumentation
Monumentation occurs throughout the Ontario
Esperanza Specific Plan community and is
designed to establish a basic hierarchy for
entering each area of the community. Along the
perimeter edges there are several entry points
into the community. At key entries a landscape
and monumentation program will be utilized to
help identify the community as well as convey
a “welcoming” feeling for both vehicular and
pedestrian traffic. Inspired by the local historical
village of “Guasti,” home of the Italian Vineyard
Company, the project monuments for Ontario
Esperanza embody some of the character of
this Ontario icon, through the use of similar
materials, architectural styles/detailing and
landscaping.

Three basic monument treatments are
used to set the hierarchy of the entries and
monumentation: the Primary Community
Entry and Monumentation, the Secondary
Community Entry and Monumentation, and the
Neighborhood Entry and Monumentation.

should occur on interior corner entries within the
Ontario Esperanza Specific Plan Community.

These entries should be used to help continue
the landscape character theme to the “core”
of the community. Each neighborhood built
within the project will have the opportunity to
identify their individual project character while
providing the basic design features of the other
monuments. Refer to The Neighborhood Entry
and Monumentation shall include the following: • Freestanding large entry pilaster set within the landscaped parkway. This pilaster should
embody the same character as that of the
Primary Community Entry Monument

8.15Parks andOpen Space
The Ontario Esperanza Specific Plan
Community will have a central “Community
Core” that centers on the Neighborhood Park
and the School. Exterior walkways and trails
should lead to this centralized area. Exhibit
46, “Pedestrian Circulation Plan” illustrates
the pedestrian accessibility and connectivity
throughout the Esperanza Specific Plan area.

Exhibits 47 through 50 illustrate the planning
concepts for the Neighborhood Park and MiniParks planned for the Esperanza Specific Plan area. • All project sites shall be designed to meet
all the Integrated Waste Department’s
requirements, including the requirements for

8.16CommunityWalls
andFencing
Walls are a major component in achieving an
overall community theme within the Ontario
Esperanza Specific Plan. A strong cohesive
appearance is achieved through the use of
“community walls” and general overall wall
guidelines as illustrated in Exhibit 52, “Master
Walls and Fence Plan” and Exhibit 53, “Wall and
Fence Details.”
All walls that adjoin community street scenes
(major streetscapes identified under Perimeter/
Interior Streetscapes) shall be deemed
“community walls.” All wall and fencing designs
and layout shall be approved by the City of
Ontario prior to construction.

8.16.1 Community Walls
Community walls shall be decorative in nature.

Community walls shall incorporate the use of
pilasters of a design consistent with the materials
of the community walls. The location and
spacing of pilasters shall be subject to Planning
Department review and approval.

8.16.2 Solid Walls and Fencing
Solid walls shall be decorative. The use of vinyl
fencing and wood fencing is prohibited. Reverse
frontage walls and any wall return that is visible
from public view, shall be constructed of splitface block or precision block that is veneered, burnished (using color other than common gray),
plastered or stuccoed, and should complement
color scheme dictated in Ontario Esperanza
Specific Plan color palette. Decorative caps and
the use of pilasters to help enhance the perimeter
appeal of the walls are encouraged. Walls visible
from the community streets may not be made of
exposed or painted precision block or slumped
block.

8.16.3 View Fencing
If applicable, view fences should be located in the
rear yards of those properties abutting large slope
areas where the adjacent property is a minimum
of 15’ above/below the house pad. These fences
allow open views but not physical access; they
shall be 5’-6” high and made of tubular steel
or lexan glass panel construction. Areas where
view fencing occurs will be subject to review by
the City of Ontario. The use of tubular steel
view fencing shall incorporate pilasters utilizing
materials consistent with adjacent walls.

8.17Outdoor Lighting
Lighting standards within the Ontario
Esperanza community shall be consistent in
style, color, and materials in order to maintain
uniformity throughout. Lighting should be
subtle, providing a soft wash of light over
illuminated objects such as monumentation.

Hierarchy shall be established by using a variety
of lighting fixtures and illumination levels based
off of lighting design intent. Lighting styles shall
tie into architectural styles and provide sufficient
illumination for the safety and well being of
the community. Preservation of “Night-Sky”
should be considered in lighting design layout
and fixture selection. Use of “cutoff ” or louvered
lamps to preserve ambiance of “Night-Sky” is
highly encouraged. Fixture locations should be
designed so that light source is not visible by
pedestrian or vehicular traffic. Frosted, louvered,
or prismatic lens should be considered where
decorative lighting fixtures are visible and part of
the aesthetic lighting program. Accent lighting
of landscape and monumentation shall be
incorporated into the following areas:

8.17.1 Entry Monument Lighting:

Avoid intensely bright or “hot” lighting of
monuments; rather, each should be lit to provide
a soft wash of light across the monument
signage. Specimen trees should be up-lit with
several fixtures into the canopy to avoid creating
dark sides of the trees.

8.17.2 Neighborhood Park/ Mini Parks/ Walkway Lighting
Lighting of the walkways, tot lots, restroom
facility, and parking areas within the Parks should
be considered for safety and security. All planned
parking areas shall have a minimum maintained
lighting level of one-foot candle (1 F.C.) or
greater. The lighting shall be from sunset to
sunrise and be operated by a photocell. The site
plan shall be provided to the Police Department.

It shall show all buildings, parking areas,
walkways, detailed landscape areas and point-bypoint photometry calculation of required light levels. Utilization of a traditional Globe/Acorn
Post mounted light fixture should be considered
for both the park open space areas as well as
interior street lighting fixtures. Keeping with
the character of traditional materials, (like those
found in the “Model Colony” in Downtown
Ontario) this will help to create a better sense of
scale to the pedestrian. Fixtures shall be vandal
resistant, not less than (8) eight feet from ground
level. Luminaries of not less than (42”) may
be utilized to illuminate a walkway if adjacent
landscaping is of a variety which does not mature
higher than (2) two feet.

8.18LandscapeDesign

8.18.1 Public Landscapes • Landscape plantings in public areas should reflect a commitment to both developing a “sense of place” and maintaining harmony
with the Ontario Ranch.
• Community Facilities District (CFD) areas
shall be separated with a 6” by 6” concrete
mow strip when adjacent to private property.
• A landscape architect licensed in California
shall be retained to prepare planting
and irrigation plans for all public areas.

Arrangement of plants should incorporate the
concepts of mass planting; plants should be
placed to allow them to grow to their natural
sizes and forms, and sheared hedges should be
kept to a minimum.

The plant matrix at the end of this section offers
a suggested plant palette for Ontario Esperanza;
while it is by no means all-inclusive, plantings
in public areas should draw primarily from this
palette for visual community continuity.

8.18.2 Front Yard Landscapes
Plantings in front yards may vary substantially
from the Ontario Esperanza palette, but should
retain some of the character and style of the
public plantings. No more than 25% of the
total square footage of any front yard shall be
lawn Turf shall not exceed 25% of the landscape
area in residential front yards; the balance shall
be composed of shrubs and groundcovers, with
an emphasis on drought tolerant plant species.

No more than 55% 45% of the front yard area
shall be hardscape. Turf areas shall be sized and
shaped to optimize irrigation efficiency. If turf
is used in isolated areas such as driveway strips,
subsurface irrigation or microspray heads shall
be required to avoid overspraying of these areas.

Irregular shapes that cannot be irrigated should
be avoided. • Each single-family lot shall be provided with front yard landscaping and a permanent
automatic irrigation system. At a minimum, a
seeded turf lawn, appropriate shrubs and trees
shall be provided as landscaping materials.

A variety of typical landscape designs shall
be provided for use on each lot within the
subdivision.
• Multiple family residential product areas shall
be provided with full landscape improvements
throughout the development. At a
minimum, a seeded turf lawn, appropriate
shrubs and trees, and a permanent irrigation

drive entries, parking, or approved outdoor
uses shall be fully landscaped; all unpaved
areas shall be landscaped; and all future
development phase areas shall be hydroseeded.

8.18.3 Soil Testing
Soil samples shall be taken from several locations
after the completion of rough grading operations,
and a reputable soil-testing laboratory shall
perform an agronomic soils test. The test
shall assess soil fertility needs for water-wise
California native and Mediterranean plant
types. No planting shall take place until the
soil has been properly prepared based on the
recommendations of the soils testing laboratory.

Organic soils amendments shall be incorporated
as necessary to achieve a recommended
percolation rate of one inch per hour.

CD-2 Design Quality
Goal A high level of design quality resulting in neighborhoods, commercial areas, public spaces, parks, and streetscapes that are attractive, safe, functional, human- scale, and distinct.

CD-2.1 Quality Building Design and Architecture. We encourage all development projects to convey visual interest and character through:

1. Building volume, massing, and height to provide context-appropriate scale and proportion;

2. A true architectural style which is carried out in plan, section, and elevation through all aspects of the building and site design and appropriate for its setting; and

3. Exterior building materials that are articulated, high quality, durable, and appropriate for the architectural style.

CD-2.2 Neighborhood Design. We create distinct residential neighborhoods that promote a sense of community and identity by emphasizing access, connectivity, livability, and social interaction through such elements as:

1. A pattern of smaller, walkable blocks that promote activity, safety, and access to nearby amenities and services;

2. Varied parcel sizes and lot configurations to accommodate a diversity of housing types;

3. Traffic calming measures to slow traffic and promote walkability while maintaining acceptable traffic flows and emergency evacuation access;

4. Floor plans that encourage views onto the street and de-emphasize the visual and physical dominance of garages (introducing the front porch as the “outdoor living room”), as appropriate; and

5. Landscaped parkways, with sidewalks separated from the curb and designed to maximize safety, comfort, and aesthetics for all users.

COMMUNITY DESIGN ELEMENT
CD-1 Image & Identity
Goal A dynamic, progressive city containing distinct and complete places that foster a positive sense of identity and belonging among residents, visitors, and businesses.

CD-1.1 City Identity. We take actions that are consistent with the City being a leading urban center in Southern California while recognizing, enhancing, and preserving the character of our existing viable neighborhoods.

Comments:

CD-1.2 Place Types. We establish Place Types in urban, mixed use, and transit-oriented areas to foster the City’s identity as a premier community and require new development within each Place Type to incorporate prescribed urban patterns, forms, and placemaking priorities.

X
Comments:

CD-1.3 Existing Neighborhoods. We require the existing character of viable residential and nonresidential neighborhoods be preserved, protected, and enhanced. X Comments:

CD-1.4 Transportation Corridors. We will enhance our major transportation corridors within the City through landscape, hardscape, signage and lighting. The extent of enhancement should be appropriate to the use, type, and context of each corridor.

X 7
Comments:

CD-1.5 View Corridors. We require all major north-south streets be designed and redeveloped to feature views of the San Gabriel Mountains, which are part of the City’s visual identity and a key to geographic orientation. Such views should be free of visual clutter, including billboards and may be enhanced by framing with trees.

CD-2.8 Safe Design. We incorporate defensible space design into new and existing developments to ensure the maximum safe travel and visibility on pathways, corridors, and open space and at building entrances and parking areas by avoiding physically and visually isolated spaces, maintaining visibility and accessibility, and using lighting.

CD-2.9 Landscape Design. We encourage durable, sustainable, and drought-tolerant landscaping materials and designs that enhance the aesthetics of structures, create and define public and private spaces, and provide shade and environmental benefits.

X 6 and 8
Comments:

CD-2.10 Parking Areas. We require all development, including single-family residential, to minimize the visual impact of surface, structured, and garage parking areas visible from the public realm in an aesthetically pleasing, safe and environmentally sensitive manner. Examples include:

1. Surface parking: Shade trees, pervious surfaces, urban run-off capture and infiltration, and pedestrian paths to guide users through the parking field.

2. Structured parking: facade articulation, screening, appropriate lighting, and landscaping.

3. Garage parking: providing access to single-family residential garages through alley access, recessing garages from the frontage to emphasize front doors or active living spaces.

Comments:

CD-2.12 Site and Building Signage. We encourage the use of sign programs that utilize complementary materials, colors, and themes. Project signage should be designed to effectively communicate and direct users to various aspects of the development and complement the character of the structures.

CD-2.4 Urban, Mixed Use, and Transit-oriented Areas. We establish Place Types to require mixed use, urban, and transit-oriented areas to be designed and developed as pedestrian oriented areas that are integrated with adjacent neighborhoods and promote a vibrant, comfortable, and functional environment, as defined for each Place Type.

Comments:

CD-2.5 Streetscapes. We design new and, when necessary, retrofit existing streets to improve walkability, bicycling and transit integration, strengthen connectivity, and enhance community identity through improvements to the public right-of-way such as sidewalks, street trees, parkways, curbs, street lighting and street furniture.

X 6 and 8
Comments:

CD-2.6 Connectivity. We promote development of local street patterns, multimodal networks, and connected public spaces that create and unify neighborhoods, rather than divide them, and create cohesive and continuous corridors, rather than independent “islands” through the following means:

1. Local street networks that provide access both between subdivisions and within neighborhoods and discourage through traffic;

2. A local street system that is logical and understandable for the user. A grid system is preferred to avoid circuitous and confusing travel paths between internal neighborhood areas and adjacent arterials and to provide adequate emergency and evacuation access; and

3. Pedestrian and bicycle networks that provide convenient access to neighborhoods and nearby destinations, such as schools, parks, other public spaces, commercial areas, and transit stops.

X 6 and 8
Comments:

CD-2.7 Sustainability. We collaborate with the development community to design and build neighborhoods, streetscapes, sites, outdoor spaces, landscaping, and buildings to reduce energy demand through solar orientation, maximum use of natural daylight, passive solar and natural ventilation, building form, mechanical and structural systems, building materials, and construction techniques.

Comments:

CD-3.5 Active Frontages. We create lively pedestrian streetscapes by requiring primary building, business, and residential entrances, outdoor dining, and storefronts be located on ground floors adjacent to sidewalks or public spaces and designed to maximize safety, comfort, aesthetics, and the intended functionality (as defined by the Place Type).
