City of San Dimas Municipal Code
Regulation to avoid or mitigate an environmental effect is found throughout the Municipal Code, but primarily in the following chapters:

1. Title 14, Water and Sewer: This section requires that the Project Proponent prepare an urban stormwater mitigation plan that implements to the maximum extent practicable, requirements established by appropriate government agencies under CEQA, Section 401 of the Clean Water Act, local ordinances, and other legal authorities intended to minimize impacts from stormwater runoff on the biological integrity of natural drainage systems and water bodies.

2. Title 15, Buildings and Construction: Contained within the Building Code is the CALGreen Code. The purpose of CALGreen is to improve public health, safety, and general welfare through enhanced design and construction of buildings using concepts that reduce negative impacts promote those principles that have a positive environmental impact and encourage sustainable construction practices.

3. Title 17, Subdivisions: These regulations govern the subdivision of land and stipulate that no land shall be divided and developed for any purpose that is not in conformity with the general plan, specific plan, or zoning code provision of the city adopted to avoid or mitigate an environmental effect. In addition, this chapter of the code specifically requires that no tentative map application shall be deemed to be complete until all documentation, determined to be necessary by the Director of the Department of Community Development, is submitted to the director and is determined by the Director to be complete, including environmental documentation required under the California Environmental Quality Act. (Ord. 795 §1, 1983)

4. Title 18, Zoning Ordinance: These regulations ensure that development is consistent with all elements of the General Plan and is in compliance with all applicable provisions of the Exhibit A

zoning code and other ordinances and regulations of the city to avoid or mitigate an environmental effect.

City of San Dimas Tree Preservation
In 1990, the City Council adopted Ordinance No. 913, which serves to preserve and protect any mature significant trees growing in the City. A tree may only be removed or relocated due to disease, development of the subject property, or health and safety concerns affecting the general public.

Other Environmental Plans

1. South Coast Air Quality Management District 2022 Air Quality Management Plan: The Air Quality Management Plan (AQMP or Plan) is a regional blueprint for achieving air quality standards and healthful air. The 2022 AQMP represents a comprehensive analysis of emissions, meteorology, regional air quality modeling, regional growth projections, and the impact of control measures.22

2. California Air Resources Board 2022 Scoping Plan: The 2022 Scoping Plan for Achieving Carbon Neutrality (2022 Scoping Plan) lays out a path to achieve targets for carbon neutrality and reduce anthropogenic greenhouse gas (GHG) emissions by 85 percent below 1990 levels no later than 2045, as directed by Assembly Bill 1279. The actions and outcomes in the plan will achieve significant reductions in fossil fuel combustion by deploying clean technologies and fuels, further reductions in short-lived climate pollutants, support for sustainable development, increased action on natural and working lands to reduce emissions and sequester carbon, and the capture and storage of carbon.23

3. Los Angeles Regional Water Quality Control Board’s Basin Plan. The Basin Plan is designed to preserve and enhance water quality and protect the beneficial uses of all regional waters. Specifically, the Basin Plan (i) designates beneficial uses for surface and ground waters, (ii) sets narrative and numerical objectives that must be attained or maintained to protect the designated beneficial uses and conform to the state's antidegradation policy, and (iii) describes implementation programs to protect all waters in the Region. In addition, the Basin Plan incorporates (by reference) all applicable State and Regional Board plans and policies and other pertinent water quality policies and regulations.24
As demonstrated throughout this Initial Study/Mitigated Negative Declaration document, the Project would not conflict with any applicable land use plan, policy, or regulation for purposes of avoiding or mitigating an environmental effect. Therefore, impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500. 22 http://www.aqmd.gov/home/air-quality/clean-air-plans/air-quality-mgt-plan 23 https://ww2.arb.ca.gov/our-work/programs/ab-32-climate-change-scoping-plan/2022-scoping-plan-documents 24 https://www.waterboards.ca.gov/losangeles/water_issues/programs/basin_plan/ Exhibit A

Impact Analysis
Project Area A is approximately 1.59 net acres and contains a single-family residence, a garage, and a shed. The General Plan and zoning designations are for single-family homes. Project Area A is surrounded on the east, west, and south by single-family residences, and to the north by a landscaping contractor business. Additionally, the California Department of Conservation’s Department of Mines and Geology has determined that mineral deposits are primarily found in the San Dimas Wash area of the City.
25 For these reasons, the development of Project Area A will not result in the loss of availability of a known mineral resource that would be of value to the region, and there are no impacts. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
The current General Plan Land Use designation for Project Area A is Single-Family Very Low (0.2-3 du/ac). The proposed General Plan Land Use designation is Single-Family Low (3.1 -6 du/ac).

These designations do not allow mineral resource recovery as an allowable use. As such, there will be no loss of a mineral resource recovery site and there are no impacts associated with the development of Project Area A. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500. 25 Initial Study for the 2021-2029 Housing Element Update City of San Dimas March 2022. https://files.sandimasca.gov/Document_Center/Department/Community%20development/San%20Dimas%20Hou sing%20Element%20Update_InitialStudy_Final%20Signed.pdf Exhibit A

Impact Analysis
Noise analysis for projects under CEQA centers on whether a project would result in significant adverse environmental effects. Whether an increase in future noise level would result in a significant effect for purposes of CEQA is determined by comparing the existing noise level (or baseline environmental setting) to the predicted noise level with the project.

City of San Dimas Noise Ordinance
The City of San Dimas Municipal Code Chapter 8.36, Noise Ordinance, sets standards for noise levels citywide and provides the means to enforce the reduction of obnoxious or offensive noises.

Regulations that are relevant to the proposed development associated with Project Area A are listed below in Table 4.13-1.

Existing Ambient Noise Levels
Traffic along East Baseline Road is the dominant source of ambient noise in the vicinity of Project Area A. One long-term and two 15-minute short-term noise measurements were taken in the vicinity of Project Area A on January 12, 2022. The purpose of the measurements was to characterize existing noise levels adjacent to Project Area A and at sensitive receptors. Figure 4-3, Noise Measurement Locations, provides an aerial photograph showing the ambient noise measurement and sensitive receiver locations, and Table 4.13-1 provides the existing ambient noise at these sites.

Construction Noise Impact Analysis
Construction of residential land uses requires heavy equipment that would increase noise levels in the immediate area. The noise from construction activity associated with the development of Project Area A would fluctuate depending on the particular type, number, and duration of use of construction equipment. Table 4.13-3, Construction Activity Noise, provides the average (Leq) noise levels produced by various construction activities at a distance of 50 feet between the construction activity and the receptor.

The City of San Dimas General Plan Noise Element states: “The impact of construction noise which occurs during the daytime is considered minimal for no more than two or three months of activity.

However, late night and weekend disturbance caused by construction noise may cause a significant impact when experienced at nearby residential locations.”26 The main source of construction noise will be from the operation of heavy equipment during grading. Project Area A is 1.59 acres, and grading is estimated to take up to 3 days.

Because neither the City of San Dimas General Plan nor Municipal Code establishes numeric maximum acceptable construction source noise levels at potentially affected receivers for CEQA analysis purposes, a numerical construction threshold based on the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual was used for analysis of daytime construction noise impacts. The FTA considers a daytime exterior construction noise level of 80 dBA Leq as a reasonable threshold for noise-sensitive residential land use.

A worst-case scenario was developed to estimate construction noise levels from the proposed development of the seven single-family homes on Project Area A, using the United States Environmental Protection Agency (USEPA) noise levels for land use construction activities at a reference distance of 50 feet. The loudest phase of construction was selected and assumed to be operating continuously. The maximum noise level for this construction phase was predicted at distances representative of locations of nearby residential homes using the sound propagation principle that states noise levels would diminish rapidly with distance from the construction site at a rate of approximately 6 dBA per doubling of distance. 26 City of San Dimas General Plan, Chapter VIII, Noise Element. https://sandimasca.gov/departments/community_development/planning_division/general_plan/general_plan_se ctions.php

Cherokee Court Residential Project
The Roadway Constriction Noise Model (RCNM) was used to determine which phase of construction activity for Project Area A would generate the greatest construction noise level. It was assumed that each construction activity would occur within a distance of 60 feet of the nearest residential receiver. The highest noise level that would be experienced at the nearest residential property is 83 dBA Leq. This noise level occurs during the project’s grading construction phase.

As noted above, the 83 dBA noise level would occur 60 feet from the homes on the east side of Cherokee Court, which is the eastern property line on Project Area A, as shown in Figure 2-1, Project Area. Because this is the edge of Project Area A, the noise level will be reduced by 6 dBA at 120 feet (which is in the middle of Project Area A) from the existing homes to the east. Therefore, it is expected the noise levels will be 77 dBA at this point, which is below the 80 dBA threshold. To the extent that construction activities were to take place, especially with heavy equipment operation, they would create noise effects on and adjacent to the construction site. However, given that the proposed development associated with Project Area A would only allow a minor incremental increase in grading activity, since Project Area A is small (1.59 acres) and grading would be minimal given the flat topography of the site, the noise impacts associated with the development of Project Area A could be considered less than significant.

Additionally, per Section 8.36.100 of the City’s Municipal Code, noise sources associated with construction are exempted from the City’s established noise standards as long as they do not take place between the hours of 8:00 p.m. and 7:00 a.m. on weekdays, including Saturday, or any time on a Sunday or public holiday. Because construction activities associated with the development of Project Area A would only occur during the allowable construction hours, the proposed Project would be consistent with the City’s Municipal Code.

However, to ensure impacts are less than significant, the following mitigation measure is required.

Mitigation Measures NOI-1. Grading Noise Reduction. The following notes shall be placed on the grading plan:
“The construction contractor will use the following source controls when working within 60 feet of occupied residential buildings:
- Use of noise-producing equipment will be limited to the interval from 7:00 a.m. to 6:00 p.m. on weekdays, 8:00 a.m. to 5:00 p.m. on Saturdays, with no construction on Sundays. - For all noise-producing equipment, use types and models that have the lowest horsepower and the lowest noise-generating potential practical for their intended use. - The construction contractor will ensure that all construction equipment, fixed or mobile, is properly operating (tuned-up) and lubricated and that mufflers are working adequately. - Have only necessary equipment onsite.
- Use manually adjustable or ambient-sensitive backup alarms”.

With the implementation of Mitigation Measure NOI-1, Grading Noise Reduction, impacts associated with the development of Project Area A would be less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Traffic Noise Impact Analysis
The increase in traffic associated with the development of Project Area A would result in noise increases on Project area roadways. In general, a traffic noise increase of 3 dBA is barely perceptible to people, while a 5‐dBA increase is readily noticeable. 27 Traffic volumes on Project area roadways
would have to approximately double for the resulting traffic noise levels to increase by 3 dBA. The proposed development associated with Project Area A would generate new vehicle trips, increasing traffic on area roadways. The CalEEMod model was used to determine the number of generated vehicle trips using the Institute of Transportation Engineers (ITE) trip rates for residential land uses.

It was determined that the proposed development associated with Project Area A would increase traffic by 66 daily trips (CalEEMod, 2020).

The proposed Project would generate new vehicle trips, thereby contributing to traffic on area roadways. Caltrans identifies Baseline Road as a major connector segment near Project Area A with an approximate ADT of 10,000. Adding 66 daily vehicle trips to the nearest segment of East Baseline Road would increase traffic along this roadway by less than 1%. Therefore, the proposed development associated with Project Area A would not generate enough traffic to result in a permanent 3‐dBA increase in ambient noise levels, and traffic noise would not exceed any local standards. Impacts associated with the development of Project Area A would be less than significant in this regard. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Stationary Equipment Noise Impact Analysis
Heating, Ventilating, and Air Conditioning Equipment Noise After Project Area A is developed with seven homes, a constant noise source may be generated from the operation of heating, ventilating, and air conditioning (HVAC) systems. However, as an industry practice, the design of the onsite HVAC units and other noise-generating mechanical equipment associated with the Cherokee Court development would typically be installed in the attics of residential units and located either within an enclosure or behind other intervening structures that would provide a level of noise shielding for nearby noise-sensitive uses. Although the operation of this equipment would generate noise, the design of these onsite HVAC units and exhaust fans would be required to comply with the regulations of the City’s Municipal Code Section 8.36.030, which states that fixed and mobile equipment or machinery noise is not allowed to exceed the noise limits outlined in Section 8.36.040 (the City’s Noise Ordinance listed above). Onsite equipment would be required, through the plan check process, to be designed and/or installed to limit noise levels that could affect nearby uses (according to the Municipal Code regulations). In addition, nighttime noise limits would apply to any equipment items required to operate between the hours of 8:00 p.m. and 7:00 a.m. When these design measures are considered with the existing urban noise environment, the noise generated from HVAC systems and other mechanical equipment at the new development site will not increase ambient noise levels by 3 dBA or greater. As a result, noise impacts on the existing and future adjacent residential uses in the area from HVAC or other mechanical equipment 27 Caltrans, Traffic Noise Analysis Protocol, April 2020, p.7-1. https://dot.ca.gov/-/media/dotmedia/programs/environmental-analysis/documents/env/traffic-noise-protocol-april-2020-a11y.pdf Exhibit A

b) Generation of excessive groundborne vibration or

✓
Impact Analysis
The proposed development of Project Area A would involve the temporary and intermittent use of construction equipment for various construction activities, resulting in the generation of groundborne vibration levels. Groundborne vibration is a concern when sensitive receptors, such as homes, are in proximity to the vibration sources. No pile driving or blasting, which are major sources of vibration levels, would be required for the proposed Project.

City of San Dimas Noise Ordinance
Section 8.36.110 Loud and/or unusual noises, H. Vibration states: “It is unlawful to operate or permit the operation of any device that creates a vibration which is above the vibration perception threshold of an individual at or beyond the property boundary of the source if on private property or at one hundred fifty feet from the source if on a public space or public right-of-way. (Ord. 868 §1, 1987)”
The background vibration velocity level in residential areas is usually around 50 vibration decibels (VdB). The vibration velocity level threshold of perception for humans is approximately 65 VdB. A vibration velocity level of 75 VdB is the approximate dividing line between barely perceptible and distinctly perceptible levels for most people. Most perceptible indoor vibration is caused by sources within buildings such as the operation of mechanical equipment, movement of people, or the slamming of doors. Typical outdoor sources of perceptible groundborne vibration are construction equipment, steel-wheeled trains, and traffic on rough roads. If a roadway is smooth, the groundborne vibration from traffic is rarely perceptible. The range of interest is from approximately 50 VdB to 100 VdB, which is the general threshold where minor damage can occur in fragile buildings.28

Construction Vibration
Groundborne vibration levels resulting from construction activities within Project Area A were estimated using data published by the FTA in its Transit Noise and Vibration Impact Assessment (2018) document. Potential vibration levels resulting from construction are identified at the nearest off-site sensitive receptor location, which consists of the adjacent single-family residential uses. vibration velocities could range from approximately 0.003 to 0.089 inch-per-second PPV at 25 feet from the source activity, depending on the type of construction equipment used, which corresponds to RMS velocity levels of 58 to 87 VdB at 25 feet, respectively, from the source activity. For this analysis, the construction vibration noise level at the nearest residential residence would be approximately 79 VdB at a distance of 60 feet. As the existing single-family residence on Project Area A would not be exposed to PPV groundborne vibration levels that exceed the 0.5 in/sec PPV threshold and the 87 VdB threshold for continuous/frequent intermittent vibration sources, vibration impacts associated with building damage and human annoyance associated with the development of Project Area A would be less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Additionally, based on previously adopted CEQA documents by the City, the vibration levels experienced at the single-family residences would be between distinctly and strongly perceptible (below 0.04 in/sec). However, construction activities would only be temporary. Any construction activities occurring along the Project Area A site boundary directly adjacent to the single-family residences would only happen for a short duration concerning the overall Project construction schedule. In addition, construction associated with the development of Project Area A would occur according to the permitted construction hours established by the City. Thus, vibration impacts associated with human annoyance would be less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Operational Vibration
The proposed residential land uses associated with the development of Project Area A would not involve stationary or mobile equipment activities that would result in high vibration levels, which are more typical for large industrial projects that employ heavy machinery. The primary vibration source would likely be vehicle circulation within and adjacent to the Project area during Project operations. However, the FTA’s Transit Noise and Vibration Impact Assessment states that it is unusual for vibration from vehicular sources (including buses and trucks) to be perceptible, even in locations close to major roads. As such, no sources of “excessive” groundborne vibration or noise levels are anticipated during the operations associated with the development of Project Area A, and there are no impacts. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

✓
Impact Analysis
As discussed in Section 4.9, Hazards and Hazardous Materials, of this Initial Study, the nearest airport is Brackett Field Airport located approximately 2 miles southeast of Project Area A. According to the Brackett Field Airport Compatibility Plan, Map 2A, Project Area A is located within Compatibility Zone E29 (see Figure 4-1, Brackett Field Airport Compatibility Zones). As shown in Figure 4-1, the noise impact associated with the development of Project Area A is “Low.” Because the proposed development is beyond the CNEL 55 dB contour, it is compatible with the Plan and will not result in excessive noise for people residing on Project Area A. As such, there are no impacts associated with the development of Project Area A. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

✓
Impact Analysis
Project Area A is located in a developed area of San Dimas and is served by existing water and sewer facilities, gas and electric utilities, and improved roadways. No additional infrastructure will be needed to serve the proposed development on Project Area A area other than connection to infrastructure adjacent to any new homes constructed.

The Project proposes to amend the General Plan Land Use Map from Single-Family Very Low (0.2-3 du/ac) to Single-Family Low (3.1-6 du/ac). Because only seven new homes would be constructed, an increase in population would result from the increase in the allowable density for VTM No. 83304.

Under the existing General Plan land use designation of Single-Family Very Low, development at the maximum density of 3 du/ac would yield up to 4 homes. Because development at the maximum density is typically not achieved because of site configuration, zoning requirements for lot depth, width, and setback requirements the realistic yield would be 2 homes. Under the proposed General Plan land use designation of Single-Family Low, development at the maximum density of 6 du/ac would yield up to 9 homes. Because development at the maximum density is typically not achieved because of site configuration, zoning requirements for lot depth, width, and setback requirements, upon approval of VTM No. 83304, the yield would be 7 homes: an increase of 5 homes over the Single-Family Very Low Land Use. The 7 homes proposed in VTM No. 83304, including the existing SF residence, will result in a net increase of 6 homes.

Based on the California Department of Finance, E-5 Population and Housing Estimates for Cities, Counties, and the State, 2020-2022, San Dimas’ population as of January 1, 2022, the persons per household is 2.66. Thus, 6 new homes would add 16 persons to the city’s population, assuming all the new residents came from outside the City limits. The current population is 34,079. 30 An
additional 16 persons would increase the population to 34,095, which is a 0.05% increase.

An increase in population of 0.05% would not result in substantial population growth. Therefore, impacts associated with the development of Project Area A are less than significant.

Additionally, because no development is proposed for Project Area B, there are no current impacts caused by the GPA and ZC to Single-Family Low and SF-7500. Regarding the impact on future 30 https://dof.ca.gov/forecasting/demographics/estimates/e-5-population-and-housing-estimates-for-citiescounties-and-the-state-2020-2023/ Exhibit A

development caused by the GPA and ZC to Single-Family Low and SF-7500; two of the three sections of Project Area B have already been fully developed. The third section, lying immediately adjacent to the west of Project Area A, currently supports two residences on approximately 1.59 acres. Under the existing General Plan land use designation of Single-Family Very Low, development at the maximum density of 3 du/ac would yield up to 4 homes. Because development at the maximum density is typically not achieved because of site configuration, zoning requirements for lot depth, width, and setback requirements, a realistic yield would be 3 homes. Under the proposed General Plan land use designation of Single-Family Low, development at the maximum density of 6 du/ac would yield up to 9 homes. Because development at the maximum density is typically not achieved because of site configuration, zoning requirements for lot depth, width, setback requirements and access issues, a more realistic yield might be 5 homes: an increase of 1 home over the Single-Family Very Low Land Use. The 5 homes, including the two existing SF residences, will result in a net increase of 3 homes.

Three new homes would add 8 people to the city’s population, assuming all the new residents came from outside the city limits. The current population is 34,079. 31 An additional 8 persons would
increase the population to 34,087, which is a 0.02% increase.

An increase in population of 0.02% would not result in substantial population growth. Therefore, impacts associated with the development of Project Area B are less than significant.

Impact Analysis
Project Area A has one home that will be demolished but replaced with seven new homes.

Therefore, implementation of the proposed Project would not displace a substantial number of existing housing, nor would it necessitate the construction of replacement housing elsewhere, and impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
As noted in Section 4.14, Population and Housing, the increase in density allowed by the General Plan amendment could result in an additional 3 homes and a population increase of 16 persons (+0.05%). The additional structures and added population would increase the demand for public services.

Fire Protection
The Los Angeles County Fire Department provides fire protection services to San Dimas. The development associated with Project Area A would be primarily served by Station No. 64, located approximately 2 miles from the Project site at 164 S. Walnut Avenue in San Dimas.

Development of Project Area A would impact fire protection services by placing an additional demand on existing fire protection resources if its resources are not augmented. To offset the increased demand for fire protection services, the Project would be conditioned by the City to provide a minimum of fire safety and support fire suppression activities, including compliance with state and local fire codes, fire sprinklers, a fire hydrant system, and paved access. The Project plans were also routed to the Fire Department for review and comment on the impacts of providing fire protection services. The Fire Department did not indicate that the Project would result in the need for new or physically altered fire facilities to maintain acceptable service ratios, response times, or other performance objectives.

Additionally, before the issuance of any building permit, a Project Proponent is required to pay development impact fees, which would address potential impacts on public services. Payment of the impact fees is required regardless of whether the project is subject to CEQA.32 Payment of the Development Impact Fee would ensure that the Project provides fair share funds for the provision of additional public services, including fire protection services, which may be applied to fire facilities and/or equipment, to offset the incremental increase in the demand for fire protection services that would be created by the Project. Based on the above analysis, impacts associated with the development of Project Area A related to fire protection are less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Police Protection
The Los Angeles County Sheriff’s Department provides community policing to San Dimas. The Project would increase the demand for police protection services. The Project plans were routed to the Sheriff’s Department for review and comment on the impacts of providing police protection services. The Sheriff’s Department did not indicate that the Project would result in the need for new or physically altered sheriff facilities to maintain acceptable service ratios, response times, or other performance objectives.

Additionally, before the issuance of any building permit, a Project Proponent is required to pay development impact fees, which would address potential impacts on public services. Payment of the impact fees is required regardless of whether the project is subject to CEQA.33 Payment of the Development Impact Fee would ensure that the Project provides fair share funds for the provision of additional public services, including sheriff protection services, which may be applied to sheriff facilities and/or equipment, to offset the incremental increase in the demand for fire protection services that would be created by the Project. Based on the above analysis, impacts associated with the development of Project Area A related to police protection are less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Schools
The Project proposes seven homes, a net increase of 6 homes, on Project Area A that may directly create additional students to be served by the Bonita Unified School District. However, the Project would be required to contribute fees to the Bonita Unified School District following the Leroy F.

Greene School Facilities Act of 1998 (Senate Bill 50). According to Senate Bill 50, payment of school impact fees constitutes complete mitigation under CEQA for Project‐related impacts on school services. As such, impacts associated with the development of Project Area A are less than 32 Initial Study for the 2021-2029 Housing Element Update City of San Dimas March 2022, p. 46. https://files.sandimasca.gov/Document_Center/Department/Community%20development/San%20Dimas%20Hou sing%20Element%20Update_InitialStudy_Final%20Signed.pdf 33 Initial Study for the 2021-2029 Housing Element Update City of San Dimas March 2022, p.46. https://files.sandimasca.gov/Document_Center/Department/Community%20development/San%20Dimas%20Hou sing%20Element%20Update_InitialStudy_Final%20Signed.pdf Exhibit A

significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Parks
Section 17.36.030, Relation of land required to population density, of the San Dimas Municipal Code establishes a parkland dedication standard of 1 acre per 100 people for recreational programs as it relates to available facilities and 3 acres per 1,000 people for neighborhood parks. However, according to Section 17.36.060, Choice of land or fee, of the San Dimas Municipal Code, the City Council may determine that an in-lieu fee payment is appropriate. Because Project Area A is only

1.59 acres, the dedication of parkland on site is not feasible. As such, payment of the in-lieu fee will compensate for the Project’s demand for additional parkland, and impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Other Public Facilities
As noted in the response to Threshold 4.14(a), Population and Housing, of this Initial Study, the development of Project Area A could add approximately 16 persons to the population of the City assuming that all new residents come from outside the City limits. This low number of persons concerning the current population of 34,079 (an increase of 0.05%), would not significantly increase the demand for public services, including public health services and library services that would require the construction of new or expanded public facilities. As such, impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
The City of San Dimas General Plan Circulation Element designates East Baseline Road as a Collector street. Cherokee Court functions as a Local street. East Baseline Road has an existing equestrian trail that abuts the southern boundary of Project Area A. The trail will remain, but Project Area A will provide a curb and gutter adjacent to the trail along the southern boundary of the site. The west side of Cherokee Court will be improved with curbs, gutters, sidewalks, and parkway landscaping.

These improvements are consistent with the programs, plans, ordinances, or policies addressing roadway, bicycle, and pedestrian facilities. Additionally, East Baseline Road does not serve as a bus line for Foothill Transit.

Based on the analysis above, the proposed development of Project Area A would not impede transit, pedestrian, or bicycle modes of travel or interfere with the operation of the roadway system. As such, impacts associated with the development of Project Area A are less than significant.

Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
Changes to CEQA Guidelines were adopted in December 2018 that require all lead agencies to adopt Vehicle Miles Traveled (VMT) as a replacement for automobile delay-based level of service (LOS) as the new measure for identifying transportation impacts for land use projects. This statewide mandate took effect July 1, 2020.

As a result, the City established VMT thresholds of significance for purposes of analyzing transportation impacts for projects subject to CEQA review and adopted Transportation Study Guidelines for Vehicle Miles Traveled and Level of Service Assessment (TS Guidelines). All projects must include a VMT assessment that explains either why the project screens out or provides a full Exhibit A

VMT impact analysis. A proposed project may screen out of full VMT analysis if it meets one or more of the following project screening criteria:

1. Transit Priority Areas Screening

2. Low VMT-generating Areas Screening

3. Project Type Screening
According to the TS Guidelines, projects generating less than 110 daily vehicle trips (e.g., 11 singlefamily housing units) can be presumed to have a less than significant impact absent substantial evidence to the contrary. The Project proposes seven single-family housing units on Project Area A; therefore, the proposed development of Project Area A is considered to have a less than significant impact, and no further VMT analysis is required. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
Access to Project Area A is already in place from East Baseline Road and Cherokee Court. The Project is proposing to construct street improvements to the west side of Cherokee Court that will meet City standards. In addition, the proposed development of Project Area A is located in an area developed with commercial and residential uses. The Project would not be incompatible with existing development in the surrounding area to the extent that it would create a transportation hazard because of an incompatible use. Therefore, impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

✓
Impact Analysis
Under Threshold 4.18 (a), the analysis considers if there are any historic resources that may also be identified as tribal cultural resources. As detailed in Section 4.5, Cultural Resources, the existing home on Project Area A is not considered eligible for the CRHR, and is not considered a historic resource under CEQA. As such, the proposed development of Project Area A will have no adverse impact on historic resources within Project Area A and no mitigation is required. Additionally, during the tribal consultation process, the home site was not identified as a tribal cultural resource by the consulting tribe(s).

However, construction of the homes allowed by VTM No. 83304 if approved, may encounter cultural resources that may also be identified as tribal cultural resources during construction-related earthmoving activities. To reduce the potential impact of an inadvertent finding of cultural resources, Mitigation Measures CUL-1 and CUL-2 under Section 4.5, Cultural Resources, require the Project Proponent to retain a qualified archaeologist to remain on call during the entirety of Project-related earth-moving operations and notify the Gabrieleño Band of Mission Indians – Kizh Nation if cultural resources are encountered during construction related earth moving activities. This would allow the Gabrieleño Band of Mission Indians – Kizh Nation to determine if the cultural resource(s) may be a tribal cultural resource(s).

With the implementation of Mitigation Measures CUL-1 and CUL-2, impacts associated with the development of Project Area A would be less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
Per the requirements identified in Table 4.18-1 Native American Tribal Consultation Notification Process under SB18 and AB52, described above, letters were sent by the City to seven local Native American Tribes on May 22, 2023, asking if they wished to participate in AB 52/SB18 consultation concerning the proposed Project.

The City received a request on September 7, 2023, from the Gabrieleño Band of Mission Indians – Kizh Nation to conduct a consultation. The Kizh nation indicated that there is a possibility that tribal cultural resources may be encountered during grading activities on Project Area A. Therefore, the following mitigation measure is required.

Mitigation Measure TCR-1: Retain a Native American Monitor. Prior to Commencement of GroundDisturbing Activities:

A. The project applicant shall retain a Native American Monitor from or approved by the Gabrieleño Band of Mission Indians – Kizh Nation. The monitor shall be retained prior to the commencement of any “ground-disturbing activity” for the subject project at all project locations (i.e., both on-site and any off-site locations that are included in the project description/definition and/or required in connection with the project, such as public improvement work). “Ground-disturbing activity” shall include, but is not limited to, demolition, pavement removal, potholing, auguring, grubbing, tree removal, boring, grading, excavation, drilling, and trenching.

B. A copy of the executed monitoring agreement shall be submitted to the lead agency prior to the commencement of any ground-disturbing activity, or the issuance of any permit necessary to commence a ground-disturbing activity.

C. The Tribal 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 Exhibit A

Vesting Tentative Tract No. 83304
Initial Study/Mitigated Negative Declaration 4.18 Tribal Cultural Resources City of San Dimas page 100
Cherokee Court Residential Project
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 and the lead agency.

D. On-site Tribal monitoring shall conclude upon the either 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 grounddisturbing 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 TCRs.

E. Upon discovery of any TCRs, all construction activities in the immediate vicinity of the discovery shall cease (i.e., 50 feet) and shall not resume until the discovered TCR has been fully assessed by the Kizh monitor and/or Kizh archaeologist and the project archaeologist.

After any necessary assessment and analysis and recordation of the finds by the Project archaeologist, the resources will be transferred to the Kizh for any purpose the Tribe deems appropriate, including for educational, cultural, and/or historic purposes.

TCR-2: Unanticipated Discovery of Human Remains and Associated Funerary 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 all construction activities in the immediate vicinity of the remains shall immediately cease. Health and Safety Code §7050.5 dictates that there shall be no further excavation of disturbance of the burial or any nearby area reasonably suspected overlie adjacent remains until the County Coroner has determined the nature of the remains. If the coroner recognizes the human remains to be those of a Native American or has reason to believe they are Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission and Public Resources Code §5097.98 shall be followed.

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

D. Construction activities may continue in other parts of the project away from discovered human remains and/or burial goods. Allowance for a time allotment sufficient to allow for Exhibit A

Vesting Tentative Tract No. 83304
Initial Study/Mitigated Negative Declaration 4.18 Tribal Cultural Resources City of San Dimas page 101
Cherokee Court Residential Project
implementation of any avoidance measures or appropriate mitigation shall occur. (CEQA Guidelines §15064.5(f).)
E. Preservation in place (i.e., avoidance) is the preferred manner of treatment for discovered human remains and/or burial goods. Any historic archaeological material that is not Native American in origin (non-TCR) shall be curated at a public, non-profit institution with a research interest in the materials, such as the Natural History Museum of Los Angeles County or the Fowler Museum if such an institution agrees to accept the material. If no institution accepts the archaeological material, it shall be offered to a local school or historical society in the area for educational purposes.

F. Any discovery of human remains/burial goods shall be kept confidential to prevent further disturbance.

TCR-3: Procedures for Burials and Funerary Remains
A. Human remains and grave/burial goods are treated the same under the California Public Resources Code. It includes soil immediately surrounding the burial or cremation, the funerary objects placed with the deceased and the ceremonial objects.

B. If the discovery of human remains includes four or more burials, the discovery location shall be evaluated as a cemetery and a separate treatment plan shall be created.

C. Associated funerary objects are objects that, as part of the death rite or ceremony of a culture, are reasonably believed to have been placed with individual human remains either at the time of death or later. Other items made exclusively for burial purposes or to contain human remains can also be considered as associated funerary objects.

D. In the case where discovered human remains cannot be fully documented and recovered on the same day, the remains will be covered with muslin cloth and a steel plate that can be moved by heavy equipment will be placed over the excavation opening to protect the remains. If this type of steel plate is not available, a 24-hour guard should be posted outside of working hours, until the burial can be suitably secured.

E. The Tribe will work with the project proponent (applicant/developer and/or landowner) to recommend measures to keep the human remains in situ and protected in place. In the event that preservation in place is not possible, despite a good faith effort by the project proponent, before ground-disturbing activities may resume in the immediate area, the landowner will designate a reburial / repatriation site. This location will be agreed upon by the Tribe and the landowner and shall be protected in place in perpetuity. There shall be no publicity regarding any cultural materials, human remains, or associated funerary objects.

F. Any occurrence of human remains and associated funerary objects that are moved from a burial location will be placed into opaque cloth bags together with any funerary objects, sacred objects, or objects of cultural patrimony. The bags will be secured in a container on Exhibit A

Vesting Tentative Tract No. 83304
Initial Study/Mitigated Negative Declaration 4.18 Tribal Cultural Resources City of San Dimas page 102
Cherokee Court Residential Project
site or in a location agreed upon by the Tribe and the project proponent. All recovered remains will be reburied within six months of recovery.

G. The Tribe will work closely with the project’s qualified archaeologist to ensure any excavation of a burial is treated carefully, ethically, and respectfully. If reburial involves data recovery approved by the Tribe, documentation shall be prepared and shall include (at a minimum) detailed descriptive notes and sketches. All data recovery data documentation related to the human remains or associated burial goods shall be approved in advance by the Tribe. If any data recovery is performed by the project archaeologist, once complete, a final report shall be submitted to the Tribe and the NAHC. Unless expressly agreed to by the Kizh, the Tribe does NOT authorize any scientific study or the utilization of any invasive and/or destructive diagnostics on human remains.

With the implementation of Mitigation Measures TCR-1 through TCR-3, impacts associated with the development of Project Area A would be less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
As detailed in Section 3.0, Project Description, and discussed throughout this Initial Study, the proposed development of Project Area A will require the installation and connection to existing utilities and service systems such as water, sewer, storm drain, electrical, natural gas, and telecommunication facilities. The construction/installation/connection of these facilities will result in some level of ground disturbance, either onsite or in the adjacent public streets. All environmental topics have either no impact or a less than significant impact except for Biological Resources, Cultural Resources, Noise, and Tribal Cultural Resources which require mitigation measures as described below.

With the implementation of Mitigation Measures BIO-1, BIO-2, CUL-1, CUL-2, NOI-1, and TCR-1 through TCR-3, impacts associated with the development of Project Area A would be less‐than‐ significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
Golden State Water Company (GSWC) provides water service to the City of San Dimas, portions of the cities of La Verne, Walnut, and Covina, and adjacent unincorporated areas of Los Angeles County. GSWC obtains its water supplies from the Main San Gabriel Basin (Main Basin) for local groundwater and treated water from Covina Irrigating Company (CIC.). GSWC also purchases treated imported water from the Metropolitan Water District of Southern California (MWD) through the Three Valleys Municipal Water District. GSWC also purchases treated water from Walnut Valley Water District (WVWD).

In addition, groundwater replenishment is delivered through the flood control channels and diverted and spread at spreading grounds through the Main Basin Watermaster’s agreement with DPW. Because the Project Site is not used as a spreading ground, it will not impede the replenishment of the Main Basin. As such, impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Project Area B, there is no increase in water demand caused by the GPA and ZC to Single-Family Low and SF-7500.

Urban Water Management Plan
Golden State Water Company – San Dimas (GSWC) is classified as an urban water supplier because it serves more than 3,000 customers (i.e., individual metered accounts) and it supplies more than 3,000 acre-feet of water annually to its customers for municipal purposes. Per the “Urban Water Management Planning Act,” which was enacted by the California Legislature in 1983, every urban water supplier (including GSWC) is required to prepare and adopt an Urban Water Management Plan (UWMP), periodically review its UWMP, and incorporate updated and new information into an updated UWMP at least once every 5 years.
34 GSWC’s UWMP projected dry-year water supplies over the next 25 years were based on the minimum supplies needed by GSWC to meet projected single-dry-year demands. Table 7-4 of the UWMP summarizes GSWC’s projected water demands and supplies over the next 25 years in 5-year increments, including during normal years, single dry years, and 5-consecutive-year drought periods. The average water demand over this period is 11,370 AFY.

The proposed development of Project Area A is forecast to generate a water demand of 4.9 acre feet per year (AFY). (600 gpd × 7 units = 4,200 gpd × 365 days = 1,533,000 gallons per year or = 4.9 AFY.35 This water demand represents only 0.04% of the average available water supply (11,370 AFY) during the next 5 years. Because the existing home on Project Area A is receiving water, the Project results in a net increase of six homes. As such, the net water demand is 3,600 gpd or 4.03 AFY, which represents 0.03% of the average available water supply (11,370 AFY) during the next 5 years.

As shown below in Table 7-4 of the UWMP, GSWC can meet water demands during normal years, single dry years, and 5-consecutive-year drought periods over the next 25 years.36 As such, impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Project Area B, there is no increase in water demand caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
GSWC wastewater is collected by gravity sewers and lift stations owned by the cities of San Dimas, Covina, La Verne, Walnut, and the Sanitation Districts of Los Angeles County (LACSD). Wastewater is transported through LACSD trunk sewers to LACSD’s San Jose Creek Water Reclamation Plant (SJCWRP).

The SJCWRP currently provides primary, secondary, and tertiary treatment for a design capacity of 100 million gallons of wastewater per day (MGD) and serves a large residential population of approximately 1,000,000 people. The City has identified a wastewater generation rate of 270 gal/day for single-family residential units.37 The Project is forecast to generate 1,890 gal/day of wastewater. 270 gal/day × 7 units = 1,890 gal/day). This represents 0.001% of the daily total wastewater treatment capacity of the SJCWRP. Because the existing home on Project Area A is served by sewer, the proposed development of Project Area A results in a net increase of six homes.

As such, the net wastewater treatment demand is 1,620 gpd which represents 0.001% of the daily total wastewater treatment capacity of the SJCWRP. As such, there is adequate capacity to serve the Project's projected demand in addition to the provider's existing commitments. As such, impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Project Area B, there is no increase in wastewater demand caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
Solid waste disposal services for San Dimas are provided by Waste Management, Inc., a private company under contract with the City. According to CalRecycle’s Jurisdiction Disposal and Alternative Daily Cover (ADC) Tons by Facility report, in 2019, the latest year for which data are 37 Project Application Materials, Environmental Information Form Part I-Initial Study, July 14, 2022.

available, approximately 94% of the solid waste landfilled from San Dimas was disposed of at the three landfills described below in Table 4.19-1. This report provides annual estimates of the disposal amounts for jurisdictions in California as reported by county and regional agency disposal reporting coordinators. The report shows the total amount disposed of by the jurisdiction at each disposal facility for a requested year.38
Construction Related Impacts
The California Green Building Standards Code (CALGreen) requires all newly constructed buildings to prepare a Waste Management Plan and divert construction waste through recycling and source reduction methods. The City of San Dimas Building and Safety Department reviews and approves all new construction projects required to submit a Waste Management Plan. Mandatory compliance with CALGreen solid waste requirements will ensure that construction waste impacts are less than significant.

In addition, as shown in Table 4.19-1 below, the landfills serving Project Area A receive well below their maximum permitted daily disposal volume and demolition, and construction waste generated by the proposed development of Project Area A is not anticipated to cause these landfills to exceed their maximum permitted daily disposal volume. Furthermore, none of these regional landfill facilities are expected to reach their total maximum permitted disposal capacities during the Project’s construction period. As such, these regional landfill facilities would have sufficient daily capacity to accept construction solid waste generated by the Project, and impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Operational Related Impacts
Based on solid waste generation usage obtained from the Project’s Summary of CalEEMod Model Runs and Output,
39 the Project would generate approximately 95.68 tons of solid waste per year or

0.26 tons per day. Table 4.19-1 compares the proposed Project development’s waste generation against the remaining landfill capacity.

Based on solid waste generation rates obtained from the California Emissions Estimator Model (CalEEMod), the Project is forecast to generate 8.2 tons of solid waste per year (or 0.02 tons per day). As shown in Table 4.19-1 above, the proposed Project development’s solid waste generation will add a minimal amount of additional solid waste to the remaining capacity of the landfills serving San Dimas. As such, the proposed Project is not anticipated to cause these landfills to exceed their remaining capacities, and impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Project Area B, there is no increase in solid waste caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
Construction Waste
Section 5.408 (Construction Waste Reduction, Disposal, and Recycling) of the 2019 California Green Building Standards Code (CALGreen; Title 24, California Code of Regulations, Part 11) requires that at least 65% of the nonhazardous construction and demolition waste from nonresidential construction operations be recycled and/or salvaged for reuse. Any future construction would include the diversion of at least 65% of demolition and construction waste for recycling or salvage in compliance with CALGreen Section 5.408. Accordingly, impacts associated with the development of Project Area A would be less than significant. Additionally, because no development is proposed for Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Operational Waste
The City’s waste hauler, Waste Management, is required to implement all applicable elements of AB 1327, Chapter 18 (California Solid Waste Reuse and Recycling Act of 1991; Public Resources Code §42901) and other applicable local, state, and federal solid waste disposal standards. This would ensure that the solid waste stream to regional landfills is reduced in accordance with existing regulations. As such, impacts associated with the development of Project Area A are less than significant. Additionally, because no development is proposed for Area B, there is no increase in solid waste caused by the GPA and ZC to Single-Family Low and SF-7500.

✓
Impact Analysis
The cumulative impacts analysis provided here is consistent with §15130(a) of the CEQA Guidelines, in which the study of the cumulative effects of a project is based on two determinations:
1) Are the combined impact of this project and other projects significant? 2) If so, is the project’s incremental effect cumulatively considerable, causing the combined impact of the projects evaluated to become significant? The cumulative impact must be analyzed only if the combined effects are significant, and the Project’s incremental effect is found to be cumulatively considerable (CEQA Guidelines 15130(a)(2) and (3)).

Cherokee Court Residential Project
The analysis of potential environmental impacts in Section 4.0, Environmental Analysis, of this Initial Study, concluded that the proposed development of Project Area A would have no impact or a less than significant impact for all environmental topics, except Biological Resources, Cultural Resources, Noise, and Tribal Cultural Resources. Mitigation Measures are required to reduce impacts to less than significant levels as discussed below. Based on the preceding analysis, the Project’s impacts associated with the development of Project Area A would not be cumulatively considerable.

Additionally, because no development is proposed for Project Area B, and the operational aspects of the existing development in these areas are part of the baseline conditions, there are no new impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Biological Resources
As discussed in Section 4.4, Biological Resources, of this Initial Study, habitat for nesting birds is present on and adjacent to Project Area A, including vegetation, open ground, stored vehicles, and structures. A red-tailed hawk (Buteo jamaicensis) was observed perched on a transmission line tower about 150 feet to the northeast of Project Area A; however, no raptor nests were observed in the tower or anywhere on or adjacent to the site. No active or inactive songbird nests were observed on or adjacent to the site during the survey. However, there is a suitable habitat for nesting birds on and adjacent to the site. Nesting birds are protected under state and federal laws.

Therefore, the Mitigation Measure BIO-1 was required to reduce impacts to a less-than-significant level.

Additionally, the trees and structures of Project Area A provide potentially suitable roosting habitat for special-status bats. No evidence of bat roosting was observed during the survey. However, the survey did not include an examination of the interior of structures. Therefore, Mitigation Measure BIO-2 was required to reduce impacts to a less-than-significant level.

Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Cultural Resources
As discussed in Section 4.5, Cultural Resources, of this Initial Study, the records search, and field survey did not identify any cultural resources, including historic and prehistoric sites or historicperiod buildings within Project Area A boundaries. The research results, combined with surface conditions, have failed to indicate sensitivity for buried cultural resources. No additional cultural resources work or monitoring are necessary during proposed activities associated with the development of the earth-moving activities. If previously undocumented cultural resources are identified during earth-moving activities, a qualified archaeologist shall be contacted to assess the nature and significance of the find, diverting construction excavation, if necessary, as required by Mitigation Measure CUL-2. Based on the preceding analysis, impacts associated with the development of Project Area A would not be cumulatively considerable. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Noise
As discussed in Section 4.13, Noise, the 83 dBA noise level would occur 60 feet from the homes on the east side of Cherokee Court, which is the eastern property line on Project Area A, as shown in Figure 2-1, Project Area. Because this is the edge of Project Area A, the noise level will be reduced by 6 dBA at 120 feet (which is in the middle of Project Area A) from the existing homes to the east.

Therefore, it is expected the noise levels will be 77 dBA at this point, which is below the 80 dBA threshold. To the extent that construction activities were to take place, especially with heavy equipment operation, they would create noise effects on and adjacent to the construction site.

However, given that the proposed development associated with Project Area A would only allow a minor incremental increase in grading activity, since Project Area A is small (1.59 acres) and grading would be minimal given the flat topography of the site, the noise impacts associated with the development of Project Area A could be considered less than significant. However, to ensure noise impacts are reduced to the maximum extent feasible, Mitigation Measure NOI-1 is required.

Tribal Cultural Resources
As discussed in Section 4.18, Tribal Cultural Resources, of this Initial Study, construction, and operation of the proposed development on Project Area A would include activities limited to the confines of Project Area A. The tribal consultation conducted through the AB 52 consultation process determined that the development of Project Area A is unlikely to adversely affect tribal cultural resources by implementing Mitigation Measures TCR-1 through TCR-3. Based on the preceding analysis, impacts associated with the development of Project Area A would not be cumulatively considerable. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Utilities and Service Systems
As discussed in Section 4.19, Utilities and Service Systems, of this Initial Study, the installation and construction of the sewer, water, and storm drainage facilities described below will result in earthmoving that may impact Biological Resources, Cultural Resources, and Tribal Cultural Resources.

Potential impacts to these resources are mitigated by Mitigation Measures BIO-1, BIO-2, CUL-1, CUL-2, and TCR-1 through TCR-3. Based on the preceding analysis, impacts associated with the development of Project Area A would not be cumulatively considerable. Additionally, because no development is proposed for Project Area B, and the operational aspects of the existing development in these areas are part of the baseline conditions, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

Impact Analysis
Under this threshold, the types of impacts analyzed consist of those that affect human health and well-being. As indicated by this Initial Study, the Project will not cause or result in certain potentially significant environmental impacts that directly affect human beings except for construction noise.

Mitigation Measure NOI-1 is required to reduce impacts associated with the development of Project Area A to less than significant levels. Additionally, because no development is proposed for Project Area B, there are no impacts caused by the GPA and ZC to Single-Family Low and SF-7500.

This section includes a list of persons, organizations and public agencies that submitted comments on the IS/MND and their respective responses. When comments did not address the completeness or adequacy of the environmental documentation, or when they did not raise environmental issues, the receipt of the comment is noted; no further response is provided as CEQA does not require a response in these instances.

The following written comments were received on the IS/MND, during the public review period. The comment letters are provided in Attachments A and B of this document.

A Caltrans, District 7 3-11-2024
Comment A-1: The Project proposes adding curbs, gutters, sidewalks, and parkway landscaping to the west side of Cherokee Court, while East Baseline Road will get only a curb and gutter. These improvements are consistent with the City of San Dimas’s programs, plans, policies, or ordinances focusing on transportation facilities. Caltrans encourages adding overall programs, plans, policies, or ordinances that focus on bicycle and pedestrian facilities. We recommend implementing additional bicycle and pedestrian elements, such as high-visibility continental crosswalk markings, high-visibility bike lane pavement markings, continuous sidewalks, and Rectangular Rapid Flashing Beacons (RRFB). Caltrans recognizes the existing pedestrian elements that enhance safety, particularly near Interstate 210 on/off-ramps. With our additional recommendations, we hope to continue enhancing the safety of pedestrians within the City of San Dimas Although the MND contains a Transportation Impact Analysis, Section 4.17, there is no analysis or determination of transportation and construction traffic impacts on Interstate 210 on/off-ramps located in the vicinity of the proposed project.

In reviewing traffic safety investigations, there are no known safety issues or concerns at the on/off-ramps at San Dimas Ave or Foothill Blvd (SR66).

Response A-1: This comment is noted. This comment is not relevant to a CEQA as traffic congestion is no longer an environmental impact per SB 743.

Comment A-2 As a reminder, construction vehicles should transport equipment to and from construction sites during non-peak hours and avoid congested freeways. Hauling trucks should be covered with a tarpaulin to avoid debris spillage onto the roadways.

Response A-2 This comment is noted.

B Eric Contreras 3/19/2024
Comment B-1: Changing the designation from SF-A 16000 to SF-7500 would have significant implications for the use and value of my property, and I believe it is not in the best interest of myself or the community.

Downzoning my parcel would likely diminish its value, as it restricts the potential uses and development options. This could have long-term financial repercussions for me and my family.

Response B-1 CEQA requires an analysis of physical impacts to the environment; it does not require analysis of social and economic impacts. Under CEQA, “an economic or social change by itself shall not be considered a significant effect on the environment.” (14 CCR §§ 15131 & 15382.) Effects analyzed under CEQA must be related to a physical change. (14 CCR § 15358(b).) Social and economic impacts alone do not constitute a significant effect on the environment. (14 CCR §§ 15064(e), 15131 & 15382.) Potential property value loss is a type of social and economic impact that in and of themselves are not physical impacts required to be included in a CEQA analysis.

Comment B-2 When I purchased this parcel, one of the primary factors influencing my decision was its current designation as SF-A 16000. Any alteration to this zoning designation undermines the expectations I had when making this significant investment.

Response B-2 This comment is noted. This comment is not relevant to a CEQA as social and economic impacts alone do not constitute a significant effect on the environment. (14 CCR §§ 15064(e), 15131 & 15382.)

ORDINANCE 1308

AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF SAN DIMAS, COUNTY OF LOS

ANGELES, CALIFORNIA, AMENDING THE OFFICIAL ZONING MAP TO CHANGE THE ZONE FROM SINGLE FAMILY AGRICULTURE 16,000 (SF-A 16,000) TO SINGLE FAMILY 7,500 (SF 7,500) FOR THE PROPERTIES LOCATED AT 327, 315 & 245 E. BASELINE ROAD (APNS:
8661-017-010, 8661-017-009 AND 8661-014-005), 1102, 1108, 1114, 1120, 1126, 1132 & 1136 CHEROKEE COURT (APNS: 8661-017-021, -022, -023, -024, -028, -029 & -027), 1117, 1121, 1129, 1139, 1145, 1151 & 1150 N. WALNUT AVENUE (APNS: 8661-014-006, -007, -008, -009, -010, -011 & 8661-017-007, AND UNADDRESSED PARCELS (APNS: 8661-017-008 & -011) WHEREAS, A Zone Change has been duly initiated by:

Development 1 Group, Inc.
2001 E. Financial Way, Ste 101
Glendora, Ca 91741
WHEREAS, the Applicant submitted a Zone Change Application (ZC 22-0001) to change the zoning of two (2) parcels from Single Family Agriculture 16,000 to Single Family 7,500; and WHEREAS, the City identified seventeen additional parcels during the initial review of the project to have the zoning changed from Single Family Agriculture 16,000 to Single Family 7,500; and
WHEREAS, the Zone Change would affect the real properties at 327, 315 & 245 E.

Baseline Road (APNs: 8661-017-010, 8661-017-009 AND 8661-014-005), 1102, 1108, 1114, 1120, 1126, 1132 & 1136 Cherokee Court (APNs: 8661-017-021, -022, -023, -024, -028, -029 & -027), 1117, 1121, 1129, 1139, 1145, 1151 & 1150 N. Walnut Avenue (APNs: 8661-014-006, - 007, -008, -009, -010, -011 & 8661-017-007, and unaddressed parcels (APNs: 8661-017-008 & - 011); and
WHEREAS, the Zone Change consists of upzoning two (2) properties, increasing the residential capacity from two (2) single-family residences to seven (7) single-family residences, an increase of four (4) potential single-family residences. This increase serves to negate the loss of three (3) separate residences, that were on three (3) separate lots zoned Light Agriculture (AL) which allowed for one (1) single-family residence per lot that was caused by Zone Change 21- 0001 (309 W. Allen Ave., 917 and 929 N. Cataract Ave.), which changed the zone from Light Agriculture (AL) to Light Manufacturing (M-1), meeting the No Net Loss provisions as required by Government Code section 66300; and
WHEREAS, at its meeting on April 18, 2024, the Planning Commission adopted Resolution PC-1677, recommending approval to the City Council of the Zone Change; and WHEREAS, notice was duly given of the City Council public hearing on the matter and that a public hearing was held on May 14, 2024, at the hour of 7:00 p.m.; and WHEREAS, the application is a project pursuant to the California Environmental Quality Act (Public Resources Code Section 21000 et seq.) ("CEQA") and an initial study was prepared to determine possible environmental impacts. On the basis of the initial study, which indicated that all potential environmental impacts from the Project were less than significant or could be

Ordinance 1308 Page 2
Zone Change 22-0001
mitigated to a level of insignificance, a Mitigated Negative Declaration was prepared pursuant to CEQA Guidelines: and
WHEREAS, a draft Mitigated Negative Declaration was prepared in accordance with CEQA Guidelines by L&L Environmental to evaluate the physical environmental impacts of the Proposed Project. The Mitigated Negative Declaration was circulated for a 30-day public/responsible agency review on February 19, 2024 through March 20, 2024 and was also made available for review on the City’s website at www.cityofsandimas.com. A complete copy of the Mitigated Negative Declaration is on file and can be viewed at the Development Services Department, 245 E. Bonita Avenue, San Dimas, California; and WHEREAS, the City gave notice of its intent to adopt the Mitigated Negative Declaration to (a) the public pursuant to Section 15072(b) of the CEQA Guidelines, (b) individuals and organizations, if any, that previously submitted written requests for notice pursuant to Section 15072(b) of the CEQA Guidelines, (c) responsible and trustee and other agencies with jurisdiction over resources that will be affected by the Proposed Project pursuant to Section 15073(c) of the CEQA Guidelines, and (d) the Clerk of the County of Los Angeles pursuant to Section 15072(a) of the CEQA Guidelines; and
WHEREAS, failure to adopt Ordinance 1308 constitutes a denial for the Proposed Project as all other associated applications are predicated on the zone change to SF-7,500.

NOW, THEREFORE, the CITY COUNCIL of the CITY OF SAN DIMAS, California, does ordain as follows:

A. The proposed zone change will not adversely affect the adjoining property as to value, precedent or be detrimental to any area.

The proposed zone change does not change the primary permitted use of single-family residences or the development standards for any of the affected properties. No new uses will be allowed that could be detrimental to surrounding properties. The primary allowed use of singlefamily residences will be consistent with the surrounding neighborhoods and should have a negligible effect on the value nor be detrimental to adjoining properties.

B. The zone change will further the public health, safety and general welfare.

The amendment will create the ability to add seven (7) new single-family residences along Cherokee Court. These houses will provide more housing options within the City, furthering the general welfare of San Dimas residents. The new residences will create more ‘eyes on the street’ along Cherokee Court and help dissuade property crime in the area. For the parcels which are not a part of the subdivision, the amended Zoning will bring the parcels into alignment with the way in which they were developed and eliminate potential animal keeping, which the parcels were not designed to accommodate, protecting the health and welfare of surrounding neighbors.

C. The zone change is consistent with the General Plan and any applicable special plans.

The density which the zone change will allow is consistent with the proposed General Plan Land Use designation of Single Family Low. It also furthers Policy HE-2.1 of the Housing Element to “Provide opportunities for new housing that responds to community needs in terms of housing type, cost, and location by providing appropriate zoning and development standards” by allowing

Ordinance 1308 Page 3
Zone Change 22-0001
for new, smaller lot residences that will provide residents with opportunities for new, more affordable housing within the City.

NOW, THEREFORE, BE IT FURTHER RESOLVED, PURSUANT TO THE ABOVE FINDINGS, that the City Council approves Zone Change 22-0001 changing the zoning classification for the subject properties as set forth on the Zone Maps in Exhibit “A” attached hereto.

SECTION 1. SEVERABILITY. If any section, subsection, subdivision, sentence, clause, phrase, or portion of this Ordinance is, for any reason, held to be invalid or unconstitutional by the decision of any court of competent jurisdiction, such decision shall not affect the validity of the remaining portions of this Ordinance. The City Council hereby declares that it would have adopted this Ordinance and each section, subsection, subdivision, sentence, clause, phrase, or portion thereof, irrespective of the fact that any one or more section, subsection, subdivision, sentence, clause, phrase, or portion thereof be declared invalid or unconstitutional.

SECTION 2. CEQA DETERMINATION. The City Council hereby finds and determines that is can be seen with certainty that there is no possibility that this ordinance may have a significant adverse effect on the environment. Thus, the adoption of this ordinance is exempt from the requirements of the California Environmental Quality Act (CEQA) pursuant to Section 15061(b)(3) of the CEQA Guidelines.

SECTION 3. EFFECTIVE DATE AND PUBLICATION. This Ordinance shall take effect 30 days after its final passage. The City Clerk shall certify to the adoption of this Ordinance and cause the same to be posted at the duly designated posting places within the City and published once within 15 days after passage and adoption as may be required by law in a newspaper of general circulation in the City of San Dimas hereby designated for that purpose; or, in the alternative, the City Clerk may cause to be published a summary of this Ordinance and certified copy of the text of this Ordinance shall be posted in the Office of the City Clerk five days prior to the date of adoption of this Ordinance; and, within 15 days after adoption, the City Clerk shall cause to be published, the aforementioned summary and shall post a certified copy of this Ordinance, together with the vote for and against the same, in the Office of the City Clerk.

WHEREAS, a draft Mitigated Negative Declaration was prepared in accordance with CEQA Guidelines by L&L Environmental to evaluate the physical environmental impacts of the Proposed Project. The Mitigated Negative Declaration was circulated for a 30-day public/responsible agency review on February 19, 2024 through March 20, 2024 and was also made available for review on the City’s website at www.cityofsandimas.com. A complete copy of the Mitigated Negative Declaration is on file and can be viewed in the Community Development Department at 245 E. Bonita Avenue, San Dimas, California; and NOW, THEREFORE, in consideration of the evidence received at the hearing, and for the reasons discussed by the City Council at the hearing, and subject to the Conditions attached as “Exhibit A”, the City Council now finds as follows:

Tentative Tract Map Findings
A. That the proposed Tract Map is consistent with the General Plan and the applicable Land Use Zone.

Resolution 2024-29 Page 3
Tentative Tract Map 22-0001
May 14, 2024
The proposed Tentative Tract Map is consistent with the proposed City of San Dimas General Plan Land Use Designation Single Family Low, which allows a density of 3.1 - 6 units per acre. The land use designation of Single Family Low is intended to provide for single-family detached units. The proposed Project will have a density of 5 units per acre and consist of detached single-family residences.

The proposed Tentative Tract Map is located within a developed area where infrastructure and utilities are readily available to serve the future development. In addition, the proposed Tentative Tract Map will be compatible with the existing residential uses that surround the Project site. The proposed seven (7) detached single-family residences will help San Dimas meet its RHNA goals and will give both San Dimas residents and prospective residents with additional housing opportunities. The design of the proposed residences have been reviewed and approval recommended by the Development Plan Review Board and will uphold the high design standards found throughout San Dimas, as well as fit into the architectural themes found in the community.

B. That the site is physically suitable for the type of development proposed.

The approximately 1.4-acre site is adequate in size for the proposed seven (7) residential parcels. All seven (7) parcels will be developed with single-family detached residences with total proposed density of 5 units per acre. The site can adequately accommodate the proposed public street, adequate vehicular and emergency vehicle access, infrastructure and all on-site and off-site improvements required of the City of San Dimas Municipal Code.

C. That the site is physically suitable for the proposed density of the development.

The site is physically suitable for the type and density of development proposed in the Tentative Tract Map. The proposed density is 5 units per acre, and will be in compliance with the proposed Land Use Designation of Single Family Low, which allows a density of 3.1 - 6 units per acre. The proposed seven (7) lot subdivision is surrounded by residential uses on three sides; therefore, the proposed infill development would be compatible with the existing fabric of the neighborhood and infrastructure can easily be extended to the Project site to serve the new land uses.

D. That the design of the subdivision or the proposed improvements is not likely to cause substantial environmental damage or substantially and avoidably injure wildlife or their habitat.

The subdivision design and improvements proposed in the Tentative Tract Map are not likely to cause substantial environmental damage nor substantially injure fish or wildlife or their habitat as none exist on the subdivision subject sites. The Project site consists of a singlefamily home with front and back yards and a field which is routinely mowed for brush abatement purposes. The development of the residences will therefore not destroy or damage any viable wildlife habitat nor, per the prepared Initial Study/Mitigated Negative Declaration, cause harm to any protected species. As such, it is not anticipated that the proposed Project will cause a substantial environmental injury to wildlife or their habitat. A Mitigated Negative Declaration has been completed for the project to comply with CEQA. The Mitigated Negative Declaration includes mitigation measures, added to the Conditions of Approval, which must be undertaken by the developer and will further ensure that any environmental impacts are minimal.

Resolution 2024-29 Page 4
Tentative Tract Map 22-0001
May 14, 2024
E. That the design of the subdivision or the type of improvements are not likely to cause serious public health problems.

The subdivision design and type of improvements proposed in the Tentative Tract Map are not likely to cause serious public health problems because all development and public improvements will be performed per the requirements of all applicable standards and codes, including the zoning and building codes. The proposed development will add seven (7) new single-family residences along a street which has already been developed with single-family residences along the opposite side of the street. In addition, the project will complete the existing cul-de-sac and add sidewalks along the western side of the street, creating a safer environment for new and existing residents.

F. That the design of the subdivision or the type of improvements will not conflict with easements, acquired by the public for access through or use of property within the proposed subdivision.

A forty-foot Metropolitan Water District (MWD) easement runs across the northern section of Lot 7, as shown on Tentative Vesting Tract Map No. 83304. No construction is being proposed in this area and Condition of Approval number 60 states that any improvements in the area will require permits from MWD. A gate will be provided by the developer to ensure that MWD has open access to the easement.

G. That the discharge of waste from the proposed subdivision into the existing sewer system will not result in a violation of existing requirements prescribed by the Regional Water Quality Control Board. Conditions are imposed to protect the public health, safety and general welfare and to implement the intent and purpose of the General Plan.

The discharge of waste into an existing sewer system from development proposed in the Tentative Tract Map will not cause a violation of existing requirements prescribed by the local water quality control board because future development must comply with County Sanitation Districts and Los Angeles County Public Works Department requirements placed on the Project at the Development Plan Design level of project review.

General Plan Amendment Findings
A. The proposed General Plan Amendment will not adversely affect the adjoining property as to value, precedent or be detrimental to any area.

The change in General Plan Land Use designation from Single Family Very Low to Single Family Low does not change the primary allowed use of the properties, which will remain detached singlefamily residences, or the way in which the properties can develop. It will also not allow new uses which could be detrimental to the surrounding properties. This should ensure that adjoining properties are not affected in any adverse way. There is also a single property with a General Plan designation of Commercial, which is developed with a residence and is part of a residential development. Amending this property to have a land use designation of Single Family Low will protect the other properties on the street by ensuring that future uses will be residential in nature, and will make the existing residential use consistent with the land use.

B. The General Plan Amendment will further the public health, safety and general welfare.

Resolution 2024-29 Page 5
Tentative Tract Map 22-0001
May 14, 2024
The amendment will create the ability to add seven (7) new single-family residences along Cherokee Court. These houses will provide more housing options within the City, furthering the general welfare of San Dimas residents. The new residences will create more ‘eyes on the street’ along Cherokee Court and help dissuade property crime in the area. For the parcels which are not a part of the subdivision, the amended General Plan designation will bring the parcels into alignment with the way in which they were developed.

C. The General Plan Amendment is consistent with the General Plan and any applicable special plans.

The General Plan amendment is consistent with Goal HE-2 of the Housing Element, to provide “Opportunities for well-designed and appropriate housing that is diverse in type, location, affordability, and tenure and that meets the full spectrum of current and future housing needs in San Dimas.” The amendment will allow for the development of four (4) more parcels than can currently be developed on the subject parcels based on the current land use, and the smaller lot size will provide more affordability than recent developments within the City.

Development Plan Review Findings
A. The development of the site in accordance with the development plan is suitable for the use or development intended.

The Project consists of seven (7) new detached single-family homes, located on land that is currently zoned for single-family residences and is surrounded to the east, south and west by tracts of single-family homes. The proposed residences will maintain the feel and character of the surrounding neighborhoods. The development of the site is suitable for single-family residences, and the development has been designed to minimize any negative effects of the new homes on the surrounding neighborhoods.

B. The total development is so arranged as to avoid traffic congestion, ensure the public health, safety and general welfare, and prevent adverse effects on neighboring property.

The seven (7) new residences have been developed to avoid traffic congestion on East Gladstone Street by taking ingress and egress off of Cherokee Court, rather than causing traffic problems and potentially harming the health, safety and general welfare by taking ingress/egress off of West Gladstone Street, a busy thoroughfare. In addition, as a condition of the development, the Project will provide for new sidewalks along the west side of Cherokee Court, improving the neighborhood for all residents and providing safer conditions for both vehicular traffic and pedestrians.

C. The development is consistent with all elements of the general plan and is in compliance with all applicable provisions of the zoning code and other ordinances and regulations of the City.

The Project is consistent with the General Plan Housing Element Goals, Policy HE 2.3, which calls on the City to “Continue to encourage housing designs, site planning, landscaping, and architectural features consistent with the General Plan, design standards, and community context.” Staff has worked with the developer to provide high quality designs that fit within the architectural themes found within the community and San Dimas. The new residences are consistent with the proposed General Plan land use designation of Single Family Low and meet all applicable provisions of the San Dimas Municipal Code.

Resolution 2024-29 Page 6
Tentative Tract Map 22-0001
May 14, 2024
Tree Removal Findings
A. It is reasonable to remove the trees because the continued existence at the location prevents the reasonable development of the subject property.

The eleven protected trees that are proposed for removal prevent the reasonable development of the property. The majority of the trees are located along the eastern property line of the property and prevent the installation of the new City sidewalks. The remaining trees are in locations that conflict with the proposed locations for the future residences.

Therefore, removal of all eleven protected trees is warranted.

MITAGATION MEASURES

65. BIO-1. Nesting Bird Survey. Project activities, including initial vegetation trimming/clearing, tree trimming/removal, ground disturbance, and demolition, shall be avoided during the nesting season (January 1 to September 15). If the nesting season cannot be avoided, a nesting bird clearance survey is required within three (3) days prior to the start of Project activities during the nesting season. If active nests are present, avoidance of nest sites is required and a buffer of 300 to 500 feet (or as determined by a biologist) is recommended until a biologist has verified that juvenile birds are no longer dependent on the nest, or the nest has otherwise become inactive. An active nest is defined as a nest with eggs, chicks, or dependent juveniles, or a nest utilized for reproduction.

66. BIO-2. Pre-Construction Bat Survey. To the extent feasible, demolition or disturbance to suitable bat roosting habitat shall be scheduled between October 1 and February 28, outside of the maternity roosting season. If trees must be removed during the maternity season (March 1 to September 30), or if structures must be removed at any time of the year, a pre-construction survey by a qualified bat specialist is required within seven (7) days prior to disturbance. Maternity season lasts from March 1 to September 30 and trees or structures determined to be maternity roosts shall be left in place until the end of the maternity season.

Hibernating colonies shall be left in place until a qualified biologist determines that the bats are no longer hibernating. Bats shall be allowed to escape prior to demolition of structures.

This may be accomplished by placing one-way exclusionary devices into areas where bats are entering a structure that allows bats to exit but not re-enter.

67. CUL-1: Worker Environmental Awareness Program. Prior to the commencement of grading or excavation, workers conducting construction activities and their foremen will receive Worker Environmental Awareness Program (WEAP) training from a qualified

Resolution 2024-29 Page 16
Tentative Tract Map 22-0001
May 14, 2024
archaeologist regarding the potential for sensitive archaeological and paleontological resources to be unearthed during grading activities. The workers will be directed to report any specimens of bone, stone, ceramics, or other archaeological artifacts or features observed during grading and/or other construction activities to their foremen and to cease grading activities in the immediate vicinity of the discovery until a qualified archaeologist and Native American cultural monitor is notified of the discovery and can assess their significance. The WEAP shall be implemented to educate all construction personnel of the area’s environmental conditions and the environmental protection measures that must be adhered to by all workers throughout the duration of Project construction. Training materials shall be language-appropriate for all construction personnel. Upon completion of the WEAP, workers shall sign a form stating that they attended the program, understand all protection measures, and shall abide by all the rules of the WEAP. A record of all trained personnel shall be kept with the construction foreman at the Project field construction office and shall be made available to any resource agency personnel. If new construction personnel are added to the Project later, the construction foreman shall ensure that new personnel receive training before they start working. The archaeologist shall provide hard copies of the WEAP presentation to the construction foreman.

68. CUL-2: Archaeological Treatment Plan. If historical or unique archaeological resources are discovered during construction, the contractor shall halt construction activities in the immediate area and notify the City. A qualified archaeologist shall be notified and afforded the necessary time to recover, analyze, and curate the find(s). Additionally, any Native American Tribe who consulted on the Project as provided for in Public Resources Code §21080.3.1(b) (AB52), shall be contacted regarding any pre-contact finds and be provided information after the archaeologist makes his/her initial assessment of the nature of the discovery. The Tribe may provide input with regard to significance and treatment. A Monitoring and Treatment Plan shall be prepared by the qualified archaeologist. The qualified archaeologist shall recommend the extent of archaeological monitoring necessary to ensure the protection of any other resources that may be in the area and afforded the necessary time and funds to recover, analyze, and curate the find(s). Construction activities may continue on other parts of the site while evaluation and treatment of historical or unique archaeological resources takes place.

69. NOI-1. Grading Noise Reduction. The following notes shall be placed on the grading plan:
a. “The construction contractor will use the following source controls when working within 60 feet of occupied residential buildings:
i. Use of noise-producing equipment will be limited to the interval from 7:00 a.m. to 6:00 p.m. on weekdays, 8:00 a.m. to 5:00 p.m. on Saturdays, with no construction on Sundays.
ii. For all noise-producing equipment, use types and models that have the lowest horsepower and the lowest noise-generating potential practical for their intended use.
iii. The construction contractor will ensure that all construction equipment, fixed or mobile, is properly operating (tuned-up) and lubricated and that mufflers are working adequately.
iv. Have only necessary equipment onsite.
v. Use manually adjustable or ambient-sensitive backup alarms”.

70. TCR-1: Retain a Native American Monitor. Prior to Commencement of Ground-Disturbing Activities:
a. The project applicant shall retain a Native American Monitor from or approved by the Gabrieleño Band of Mission Indians – Kizh Nation. The monitor shall be retained prior to the commencement of any “ground-disturbing activity” for the subject project at all project locations (i.e., both on-site and any off-site locations that are included in the project description/definition and/or required in connection with the project, such as public improvement work). “Ground-disturbing activity” shall include, but is not limited to, demolition, pavement removal, potholing, auguring, grubbing, tree removal, boring, grading, excavation, drilling, and trenching.
b. A copy of the executed monitoring agreement shall be submitted to the lead agency prior to the commencement of any ground-disturbing activity, or the issuance of any permit necessary to commence a ground-disturbing activity. c. The Tribal 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 and to the lead agency.
d. Tribal monitoring shall conclude upon the following: (1) written confirmation to the Kizh from a designated point of contact for the project applicant or lead agency that all ground-disturbing activities and phases that may involve ground-disturbing activities on the project or in connection with the project are complete; or (2) a determination and written notification by the Kizh to the project applicant and lead agency that no future, planned construction activity and/or development/construction phase at the project site possesses the potential to impact TCRs.
e. Upon discovery of any TCRs, all construction activities in the immediate vicinity of the discovery shall cease (i.e., 50 feet) and shall not resume until the discovered TCR has been fully assessed by the Kizh monitor and the Kizh archaeologist. After any necessary assessment and analysis and reporting of the finds by the project archaeologist, the resources will be transferred to the Kizh for any purpose the Tribe deems appropriate, including for educational, cultural, and/or historical purposes.

71. TCR-2: Unanticipated Discovery of Human Remains and Associated Funerary Objects a. Native American human remains are defined in PRC §5097.98 (d)(1) as an inhumation or cremation in any state of decomposition or skeletal completeness.

Funerary objects, called associated grave goods in Public Resources Code §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 all construction activities in the vicinity of the discovery shall immediately cease. Health and Safety Code §7050.5 dictates that there shall be no further excavation of disturbance of the burial or any nearby area reasonably suspected overlie adjacent remains until the County Coroner has

Resolution 2024-29 Page 18
Tentative Tract Map 22-0001
May 14, 2024
determined the nature of the remains. If the coroner recognizes the human remains to be those of a Native American or has reason to believe they are Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission and Public Resources Code §5097.98 shall be followed.
c. Human remains and grave/burial goods shall be treated alike per California Public Resources Code §5097.98(d)(1) and (2).
d. Construction activities may resume in other parts of the project site away from discovered human remains and/or burial goods. (CEQA Guidelines §15064.5(f).) e. Preservation in place (i.e., avoidance) is the preferred manner of treatment for discovered human remains and/or burial goods. Any historic archaeological material that is not Native American in origin (non-TCR) shall be curated at a public, non-profit institution with a research interest in the materials, such as the Natural History Museum of Los Angeles County or the Fowler Museum, if such an institution agrees to accept the material. If no institution accepts the archaeological material, it shall be offered to a local school or historical society in the area for educational purposes.
f. Any discovery of human remains/burial goods shall be kept confidential to prevent further disturbance.

72. TCR-3: Procedures for Burials and Funerary Remains:
a. The term “human remains” encompasses more than human bones and includes the soil immediately surrounding the burial or cremation, the funerary objects placed with the deceased and ceremonial objects.
b. If the discovery of human remains includes four or more burials, the discovery location shall be evaluated as a cemetery and a separate treatment plan shall be created.
c. Associated funerary objects are objects that, as part of the death rite or ceremony of a culture, are reasonably believed to have been placed with individual human remains either at the time of death or later. Other items made exclusively for burial purposes or to contain human remains can also be considered as associated funerary objects.
d. In the case where discovered human remains cannot be fully documented and recovered on the same day, the remains will be covered with muslin cloth and a steel plate that can only be moved by heavy equipment will be placed over the excavation opening to protect the remains. If this type of steel plate is not available or suitable for use, a 24-hour guard should be posted outside of working hours until the remains can be suitably secured from disturbance. e. The Tribe will work with the project proponent (project applicant/developer and/or landowner) to recommend measures to keep the human remains in situ and protected in place. In the event that preservation in place is not possible, despite a good faith effort by the project proponent, before ground-disturbing activities may resume in the immediate area, the landowner will designate a reburial /repatriation site. This location will be agreed upon by the Tribe and the landowner and shall be protected in perpetuity. There shall be no publicity regarding any cultural materials, human remains, or associated funerary objects. f. Any human remains and associated funerary objects that are moved from a burial location will be placed into opaque cloth bags together with any associated funerary objects, sacred objects, and objects of cultural patrimony. The bags will be secured in a container on site or in a location agreed upon by the Tribe and the

project proponent. All recovered remains will be reburied within six months of recovery.
g. The Tribe will work closely with the project’s qualified archaeologist to ensure any excavation is treated carefully, ethically, and respectfully. If reburial involves data recovery approved by the Tribe, documentation shall include (at a minimum) detailed descriptive notes and sketches. All data recovery documentation related to the human remains or associated burial goods shall be approved in advance by the Tribe. If any data recovery is performed by the project archaeologist, once analysis is complete, a final report shall be written and submitted to the Tribe and the NAHC. Unless expressly agreed to by the Kizh, the Tribe does NOT authorize any scientific study or the utilization of any invasive and/or destructive diagnostics on human remains.

SUMMARY
The Applicant, Stan Stringfellow on behalf of Development 1 Group, has submitted an application for the development of a seven (7) parcel subdivision, to be associated with the construction of seven (7) detached single-family residences. The development will require a General Plan Amendment to change the underlying land use from Single-Family Very Low to Single-Family Low, a Zone Change from Single-Family Agriculture (SF-A) 16,000 to SingleFamily (S-F) 7,500, and the removal of 11 mature protected trees. 17 additional properties near the two (2) properties which make up the subdivision site will also have their General Plan designation and Zoning changed as a part of the project. The subdivision project will be located at 327 E. Baseline Road and the unaddressed parcel directly to the north, on the northeast corner of E. Gladstone Street and Cherokee Court. The additional 17 properties are located at 1102, 1108, 1114, 1120, 1126, 1132 & 1136 Cherokee Court, 315 E. Baseline Road and an Attachment 4

TTM 22-0001, GPA 23-0001, ZC 22-0001, DPRB 22-0015 and TRP 22-0029 Page 2 For the Meeting of April 18, 2024
unaddressed parcel, 245 E. Baseline Road, and 1117, 1121, 1129, 1139, 1145, 1151 & 1150 N. Walnut Avenue. The properties are currently developed with single-family residences, which would be demolished as a part of the proposed development.

On March 28, 2024, the Development Plan Review Board, at a regularly scheduled meeting, recommended approval to the Planning Commission of DPRB No. 22-0015 and TRP 22-0029 for the design and construction of seven (7) detached single-family residences along with the associated removal of 11 mature trees.

RECOMMENDATION
Staff and the Development Plan Review Board recommend that the Planning Commission • Adopt Resolution PC-1677, recommending approval of DPRB Case No. 22-0015 and TRP 22-0029 to the City Council.

Staff recommends that the Planning Commission
• Adopt Resolution PC-1676, recommending adoption of the Initial Study/Mitigated Negative Declaration to the City Council, and Resolution PC-1677, recommending approval of TTM 22-0001, GPA 23-0001 and ZC 22-0001 to the City Council.

FISCAL IMPACT
The scope of the project includes expanding the width of Cherokee Court from the cul-de-sac to Baseline Road as well as adding sidewalks and trees that are not currently in place. The additional increase in street size and the new sidewalks and trees would have to be maintained by the City moving forward. While the new developments would generate property tax income, it is unlikely to generate enough revenue to support future maintenance and replacement costs of the additional assets.

BACKGROUND
The Applicant, Stan Stringfellow, on behalf of Development 1 Group, submitted an application for the construction of seven (7) detached single-family residences and the associated removal of 11 mature trees in conjunction with Tentative Vesting Tract Map 22-0001 (83304), General Plan Amendment 23-0001 and Zone Change 22-0001. The development will be located at 327 E.

Baseline and the vacant lot directly to the north, located on the northwest corner of E. Baseline Road and Cherokee Court. The property is located within the Single-Family Agriculture (SF-A) 16,000 Zone. 327 E. Baseline Road is currently developed with a single-family residence, while the attached lot is vacant.

During review of the proposed project, Staff determined that 17 surrounding properties should have their Zoning and Land Use designation updated to create a single area of Single-Family zoned parcels with a Single Family Low land use designation, as well as to be in compliance with their current development and minimum parcel size. At a City Council Study Session on March 23, 2021, the Council agreed with Staff’s recommendation and found that there was merit to allow for the formal submittal of applications to request a General Plan Amendment and Zone Change for all the affected parcels, as well as the associated development applications.

At its March 28, 2024, regular meeting, the Development Plan Review Board (DPRB) considered DPRB No. 22-0015 for the design and construction of seven (7) detached single family residences

TTM 22-0001, GPA 23-0001, ZC 22-0001, DPRB 22-0015 and TRP 22-0029 Page 3 For the Meeting of April 18, 2024
and TRP No. 22-0029 for the associated removal of 11 mature trees. After consideration, the DPRB recommended approval of the two applications to the Planning Commission, subject to the attached Conditions of Approval. The DPRB modified Condition 25, associated with the replacement of trees on the property, to call out the total number of replacement trees, add that 25% of the replacement trees must be 24” box, and to add for three (3) oak trees among the replacement trees to account for the removal of three (3) mature oaks due to the project. The DPRB did not take action on the Vesting Tentative Tract Map, General Plan Amendment or the Zone Change, as it was not under their purview.

The Planning Commission will consider and take action on all five applications (TTM 22-0001, GPA No. 23-0001, ZC No. 22-0001, DPRB No. 22-0015, and TRP No. 22-0029) in addition to the associated Initial Study/Mitigated Negative Declaration (IS/MND).

DISCUSSION/ANALYSIS
The proposed subdivision project site is 1.4 acres in size and is located at the northwest corner of E. Baseline Road and Cherokee Court (See Figure 1). The property is currently zoned SF-A 16,000, as are the properties across Cherokee Court to the east and the adjacent property to the west. Zone Change 22-0001, which is associated with the project, seeks to rezone these properties, along with others along Walnut Avenue, to SF-7,500, thus the proposed development has been designed to meet the SF-7500 development standards.

Vesting Tentative Tract Map
The proposed subdivision will subdivide two (2) parcels to create seven (7) new lots and complete the end of the cul-de-sac street, bringing it up to Public Works’ standards (See Attachment 3 – Tentative Tract Map 83304). The Applicant has submitted a vesting Tentative Tract Map, which locks in place the development standards and regulations that may be applied to the properties.

All seven (7) new residences will front on and have vehicular access from Cherokee Court.

The new lots will range in area from 7,920 square feet to 11,293 square feet, which will meet the minimum lot area required for the SF-7,500 zone. The table below shows the proposed lot size for each lot, with residence size and lot coverage.

(4,843 Sq Ft Option) 23.72%
Per the development standards for the proposed SF-7500 zone, lots of 7,500 square feet to 9,999 square feet must have a minimum width of 70 feet at the street. This minimum width may be reduced to thirty-five (35) feet for lots on a cul-de-sac, provided that the lot expands to at least the minimum width otherwise required (SDMC 18.24.040(C)(1). As seen in Attachment 3 - Vesting Tentative Tract Map 83304, Lots One through Six meet the required 70-foot minimum width, while Lot Seven is less than 70 feet, but as it is located on a cul-de-sac and does expand to be greater than the 70-foot minimum width, meets the width requirements of the San Dimas Municipal Code.

As a condition of the development, the Applicant will be responsible for completing the existing public cul-de-sac street to Public Works’ standards. The project will require a ten (10) foot dedication along the west side of Cherokee Court for a sidewalk and public right-of-way. The Applicant will also be required to construct all sidewalks and plant public trees which will then be dedicated to and maintained by the City.

General Plan Amendment
All properties in San Dimas have been identified in the San Dimas General Plan Land Use Element and been assigned a land use. This land use designation controls what new uses can be developed on a given property at a basic level, such as commercial, industrial or residential.

For residential properties, the General Plan designation can also dictate the density of a given parcel. For example, San Dimas uses the General Plan designations of, among others, SingleFamily Very Low, which allows 0.2 to 3 units per acre, Single-Family Low which allows 3.1 to 6 units per acre and Low/Medium, which allows 6.1 to 8 units per acre. It is important to note that

TTM 22-0001, GPA 23-0001, ZC 22-0001, DPRB 22-0015 and TRP 22-0029 Page 5 For the Meeting of April 18, 2024
the General Plan designation only dictates the general use for a property, not the specific uses which will be allowed or the development standards that would apply to a property. The specifics on how a property may develop are contained within the zoning code, which must not contradict the General Plan designation.

Currently, the proposed subdivision project site at 327 E. Baseline Rd. and the adjacent lot to the north, have a General Plan designation of Single-Family Very Low, which allows for 0.2 to 3 units per acre. In order to reach the density proposed for the development, five (5) units per acre, the properties will need to have their General Plan designation changed to Single-Family Low, which allows for 3.1 to 6 units per acre.

In addition to the two (2) subject parcels, Staff is proposing to amend the General Plan designation for the six (6) lots on the east side of Cherokee, the three (3) adjacent lots directly to the west of the subject property, and the seven (7) lots on the west side of N. Walnut Avenue from SingleFamily Very Low to Single-Family Low as a part of the project. There is one lot at the end of Cherokee Court that is designated as Commercial but has been developed with a residence that will also have its Land Use designation changed to Single-Family Low. This will create a contiguous area of Single-Family Low designated properties north of E. Baseline Road from the east side of N. Dixie Drive to the west side of N. Walnut Avenue. The seven (7) lots on N. Walnut range from 7,500 to 9,386 square feet and are not in compliance with the density limits prescribed by the current General Plan designation. Amending the General Plan designation for these lots to Single-Family Low corrects the situation, bringing the lots into compliance with the General Plan. The seven (7) lots on the east side of Cherokee are fully developed and do not have the street frontage to be subdivided any further. Changing the General Plan designation for these lots would not, even with the increased density provided by the Single-Family Low designation, allow for any further residential development, besides that already allowed by law, for these lots. Only the lots directly to the west could potentially be subdivided and take advantage of the extra density provided by the General Plan amendment. However, as these lots will be landlocked with no direct access to a residential street, the redevelopment possibilities for these lots, even with the increase in potential density, will be limited. While the amendment is required to allow the development to move forward, the amendment will also bring some consistency to the neighborhood and correct existing noncompliance density situations discussed above.

Zone Change
In order for the development to be allowed, the Applicant is requesting a zone change for the two (2) subject lots from Single-Family Agriculture 16,000 to Single-Family 7,500. When Staff completed a preliminary review of the Applicant’s application, Staff requested that the seven (7) parcels along the east side of Cherokee Court, the three (3) parcels directly to the west of the subject site, and seven (7) parcels on the west side of N. Walnut Avenue to be included in the rezoning in order to create a contiguous area of SF-7,500 zoning and to correct the zoning on properties that are currently non-conforming with the San Dimas Municipal Code. For SingleFamily zoning, the numbers after the zone indicate the minimum lot size for any new developments. In this case, the Applicant is asking for Single-Family zoning with a 7,500 square foot minimum lot size. The development standards for Single-Family and Single-Family Agriculture are identical; the Single-Family Agriculture section of the code refers to the SingleFamily section for all development standards. Changing the zoning on any lot currently zoned SFA 16,000 will not create any non-conforming residences, as all residences were designed to meet the SF zone standards, including minimum lot size.

Per the standards of the SF-A Zone, Horse keeping is allowed on SF-A lots as long as they are at least 16,000 square feet in total area. The change of zoning from SF-A 16,000 to S-F 7,500 would eliminate the ability to keep horses on the properties to be rezoned. However, the seven (7) lots on N. Walnut Ave and six (6) of the seven existing (7) lots on Cherokee are under 16,000 square feet, meaning that horse keeping would not be an option even with the SF-A zoning. The northernmost lot on Cherokee Court, at 21,511 square feet, is large enough to keep horses, but is developed in such a way that meeting the distance requirements for corrals, 80 feet from residential structures on adjacent lots and 35 feet from residential structures on the subject lot, would be difficult to achieve, effectively eliminating the ability to keep horses. Of the three (3) adjacent lots to the west, only the bottom two (2) are large enough to currently keep horses.

Rezoning these properties would remove the ability to keep horses from these parcels.

Figure 3 – Existing Zoning Map (on left) and Proposed Zoning Map (on right). Areas to be rezoned are outlined in dashed lines.

TTM 22-0001, GPA 23-0001, ZC 22-0001, DPRB 22-0015 and TRP 22-0029 Page 7 For the Meeting of April 18, 2024
The Single-Family Agriculture zone also allows for the keeping of potbellied pigs and other domestic animals. Potbellied pigs are subject to the same lot size requirements as horses, therefore only the two (2) large lots directly to the west would lose the ability to keep these pigs as pets. Other domestic animals, such as rabbits, fowl (excluding chickens), calves, goats and sheep, are allowed to be kept on any parcel greater than 11,000 square feet. All of the parcels on the east side of Cherokee Court and the three (3) parcels directly to the west are larger than 11,000 square feet. The rezoning would remove the right for these lots to keep the above animals.

Chickens, ducks and geese are allowed in the SF zone on any lot over 11,000 square feet, so properties would not lose the right to keep the above fowl, although the number of birds allowed would be reduced from a maximum of 20 to a maximum of 4.

Grading and Fencing
Cherokee Court currently sits slightly higher than the two lots on which development is proposed.

This difference runs from four (4’) feet to portions where the street is basically level with the property. To allow for level lots and proper drainage, the parcels will be raised to be slightly higher than Cherokee Court. The parcels will also be graded to be slightly higher along the western property line to allow for drainage from the rear of the property towards Cherokee Court. Due to this, there will be an elevation difference between the newly created parcels and the existing parcels to the west.

A six (6) foot decorative masonry wall (tan split face with finished cap) is proposed to run along the rear (western) and street side (southern) property lines of the development. Due to the differences in elevation between the two properties, the masonry retaining walls (tan split face) may reach up to four (4) feet if measured from the adjacent property which, as described above, will sit lower than the proposed parcels. The combined height of the masonry wall and the retaining wall will be 10 feet at its highest level measured from the adjacent property to the west.

The interior walls separating the individual lots will be tan split face masonry walls to match the perimeter walls.

House Design
Two (2) different floor plans are being proposed for the project. Each floor plan is a two-story residence and will have two (2) different exterior treatments, a Spanish style and a “Del Norte” style, to provide variety among the residences (See Attachment 4 – Project Plans). Each floor plan will also have options to increase the livable space of a residence; these optional areas do not increase the lot coverage for any given parcel. The table below provides an overview for each plan.

four (4) bedrooms and 3.5 baths, with a primary bedroom with en suite bathroom and walk-in closet being on the first floor. An optional home office/playroom removes the tandem parking space in the garage to add a 166 square foot room to the first floor.

Floor plan ‘A’ will be offered in two (2) exterior treatments; a Spanish style and a “Del Norte” style.

The Spanish style will feature a sand stucco finish, S-tile concrete roof tiles, decorative iron vents, and decorative accent shutters (See Figure 4). The front door, garage door and window shutters will be a dark wood to provide contrast to the light stucco. The “Del Norte” style will feature a sand stucco finish, S-tile concrete roof tiles, foam accent trim around the front windows, and a brick accent wall on the front façade (See Figure 5). Exposed corbels will accent the roof line on all facades. Refer to Attachment 5 for the color and material boards.

Floor plan ‘B’ has a standard layout with 3,321 square feet of floor area and a 658 square foot three-car garage. The standard plan includes four (4) bedrooms and 3.5 baths, with a primary bedroom with en suite bathroom and walk-in closet on the first floor. An optional addition to the residence will add 864 square feet of space to the second floor with options for a second primary bedroom, or an additional two (2) bedrooms with upstairs laundry.

Floor plan ‘B’ will also be offered in two (2) exterior treatments. The Spanish style will feature a sand stucco finish, S-tile concrete roof tiles, foam accents around the windows, a brick accent wall and decorative tiles along the front façade (See Figure 6). The front door, window trim, roof and front accent walls are a dark color to provide contrast with the light stucco. The “Del Norte” style will feature S-tile concrete roof tiles, a stone accent wall on the front façade with a half stone wall under the front window, foam corbels, and foam trim around the windows (See Figure 7).

Development Standards
The proposed project is associated with Zone Change 22-0001, which seeks to change the existing zoning of Single-Family Agriculture (SF-A) 16,000 to Single-Family (SF) 7,500. Per the proposed zoning, all residences must have a front yard setback of at least 20 feet, side setbacks of 12 feet on the driveway side and 5 feet on the opposite side, street side setback 10 feet, and a maximum building height of 35 feet. As illustrated in the table below, all of the proposed residences meet these standards.

Tree Removal
The proposed development will require the removal of 21 trees; one dead tree, nine (9) trees which do not meet the minimum size criteria set forth in the San Dimas Municipal Code and 11 mature trees. Of the 11 mature trees, there are five (5) oaks and one (1) each of Xylosma, Tillea, Chorissia, Liquidambar, Mexican Fan Palm and Pecan (See Attachment 6 – Arborist Report).

Of the 11 mature trees to be removed, five (5) trees, which includes four (4) oak trees, are along the eastern property line adjacent to Cherokee Court. As a condition of approval for the tract map, the applicant is being required to complete the street and provide a sidewalk on the west side of Cherokee Court. This condition necessitates the removal of the trees along Cherokee Court. The remaining six (6) trees are located in locations that either prevent the demolition of the existing residence or constrain the development of the new residences. See Attachment 7 – Tree Mitigation Plan for the locations of all existing and proposed trees.

The Applicant has provided a landscape plan that proposes 42 new trees spread among the seven (7) parcels. The removal of the 11 mature trees will require 22 replacement trees. The Development Plan Review Board called for 25% of the replacement trees to be a minimum of 24- inch box in size and for three (3) oaks to be replanted on the property due to the removal of three (3) mature oak trees. The remaining 20 trees are being provided as part of the landscape plan for the development. Of the 42 trees, 17 will be California Sycamore trees that will be planted as street trees. The remaining trees will consist of 20 trees to be planted in the front yards of the seven (7) parcels, and five (5) trees being planted as screening along the northern most property line. Parks and Recreation has reviewed the proposed tree plan and has not expressed any issues to Staff.

ALTERNATIVES
There are no alternative proposed for this request. The Planning Commission may recommend changes to the project or may recommend denial of the General Plan Amendment, the Zone

TTM 22-0001, GPA 23-0001, ZC 22-0001, DPRB 22-0015 and TRP 22-0029 Page 11 For the Meeting of April 18, 2024
Change and/or the Mitigated Negative Declaration. However, denying any individual action is recommending denial of the project, as the project may not move forward without all of the actions being approved.

ENVIRONMENTAL REVIEW
The proposed development is a project pursuant to the California Environmental Quality Act (CEQA) and an Initial Study was prepared to determine possible environmental impacts. On the basis of the Initial Study, which indicated that all potential environmental impacts from the project were less than significant or could be mitigated to a level of insignificance, a MND was prepared pursuant to CEQA guidelines. The MND was circulated for the required 30-day public review period from February 19, 2024 until March 20, 2024. Staff received two comments during the comment period, one from Caltrans encouraging bicycle and pedestrian facilities/improvements and recommendations for construction vehicles and one from an affected resident which did not agree with the rezoning. These comments, and any responses, have been provided in Exhibit A to Attachment 1, Responses to Comments.

RESOLUTION PC-1677 Page 3
NOW, THEREFORE, in consideration of the evidence received at the hearing, and for the reasons discussed by the Commissioners at the hearing, and subject to the Conditions attached as “Exhibit A”, the Planning Commission now finds as follows:

Tentative Tract Map Findings
A. That the proposed Tract Map is consistent with the General Plan and the applicable Land Use Zone.

The proposed Tentative Tract Map is consistent with the proposed City of San Dimas General Plan Land Use Designation Single Family Low, which allows a density of 3.1 - 6 units per acre. The land use designation of Single Family Low is intended to provide for single-family detached units. The proposed Project will have a density of 5 units per acre and consist of detached single-family residences.

The proposed Tentative Tract Map is located within a developed area where infrastructure and utilities are readily available to serve the future development. In addition, the proposed Tentative Tract Map will be compatible with the existing residential uses that surround the Project site. The proposed seven (7) detached single-family residences will help San Dimas meet its RHNA goals and will give both San Dimas residents and prospective residents with additional housing opportunities. The design of the proposed residences have been reviewed and approval recommended by the Development Plan Review Board and will uphold the high design standards found throughout San Dimas, as well as fit into the architectural themes found in the community.

B. That the site is physically suitable for the type of development proposed.

The approximately 1.4-acre site is adequate in size for the proposed seven (7) residential parcels. All seven (7) parcels will be developed with single-family detached residences with total proposed density of 5 units per acre. The site can adequately accommodate the proposed public street, adequate vehicular and emergency vehicle access, infrastructure and all on-site and off-site improvements required of the City of San Dimas Municipal Code.

C. That the site is physically suitable for the proposed density of the development.

The site is physically suitable for the type and density of development proposed in the Tentative Tract Map. The proposed density is 5 units per acre, and will be in compliance with the proposed Land Use Designation of Single Family Low, which allows a density of 3.1 - 6 units per acre. The proposed seven (7) lot subdivision is surrounded by residential uses on three sides; therefore, the proposed infill development would be compatible with the existing fabric of the neighborhood and infrastructure can easily be extended to the Project site to serve the new land uses.

D. That the design of the subdivision or the proposed improvements is not likely to cause substantial environmental damage or substantially and avoidably injure wildlife or their habitat.

The subdivision design and improvements proposed in the Tentative Tract Map are not likely to cause substantial environmental damage nor substantially injure fish or wildlife or their habitat as none exist on the subdivision subject sites. The Project site consists of a singlefamily home with front and back yards and a field which is routinely mowed for brush

RESOLUTION PC-1677 Page 4
abatement purposes. The development of the residences will therefore not destroy or damage any viable wildlife habitat nor, per the prepared Initial Study/Mitigated Negative Declaration, cause harm to any protected species. As such, it is not anticipated that the proposed Project will cause a substantial environmental injury to wildlife or their habitat. A Mitigated Negative Declaration has been completed for the project to comply with CEQA. The Mitigated Negative Declaration includes mitigation measures, added to the Conditions of Approval, which must be undertaken by the developer and will further ensure that any environmental impacts are minimal.

E. That the design of the subdivision or the type of improvements are not likely to cause serious public health problems.

The subdivision design and type of improvements proposed in the Tentative Tract Map are not likely to cause serious public health problems because all development and public improvements will be performed per the requirements of all applicable standards and codes, including the zoning and building codes. The proposed development will add seven (7) new single-family residences along a street which has already been developed with single-family residences along the opposite side of the street. In addition, the project will complete the existing cul-de-sac and add sidewalks along the western side of the street, creating a safer environment for new and existing residents.

F. That the design of the subdivision or the type of improvements will not conflict with easements, acquired by the public for access through or use of property within the proposed subdivision.

A forty-foot Metropolitan Water District (MWD) easement runs across the northern section of Lot 7, as shown on Tentative Vesting Tract Map No. 83304. No construction is being proposed in this area and Condition of Approval number 60 states that any improvements in the area will require permits from MWD. A gate will be provided by the developer to ensure that MWD has open access to the easement.

G. That the discharge of waste from the proposed subdivision into the existing sewer system will not result in a violation of existing requirements prescribed by the Regional Water Quality Control Board. Conditions are imposed to protect the public health, safety and general welfare and to implement the intent and purpose of the General Plan.

The discharge of waste into an existing sewer system from development proposed in the Tentative Tract Map will not cause a violation of existing requirements prescribed by the local water quality control board because future development must comply with County Sanitation Districts and Los Angeles County Public Works Department requirements placed on the Project at the Development Plan Design level of project review.

General Plan Amendment Findings
A. The proposed General Plan Amendment will not adversely affect the adjoining property as to value, precedent or be detrimental to any area.

The change in General Plan Land Use designation from Single Family Very Low to Single Family Low does not change the primary allowed use of the properties, which will remain detached singlefamily residences, or the way in which the properties can develop. It will also not allow new uses which could be detrimental to the surrounding properties. This should ensure that adjoining properties are not affected in any adverse way. There is also a single property with a General

RESOLUTION PC-1677 Page 5
Plan designation of Commercial, which is developed with a residence and is part of a residential development. Amending this property to have a land use designation of Single Family Low will protect the other properties on the street by ensuring that future uses will be residential in nature, and will make the existing residential use consistent with the land use.

B. The General Plan Amendment will further the public health, safety and general welfare.

The amendment will create the ability to add seven (7) new single-family residences along Cherokee Court. These houses will provide more housing options within the City, furthering the general welfare of San Dimas residents. The new residences will create more ‘eyes on the street’ along Cherokee Court and help dissuade property crime in the area. For the parcels which are not a part of the subdivision, the amended General Plan designation will bring the parcels into alignment with the way in which they were developed.

C. The General Plan Amendment is consistent with the General Plan and any applicable special plans.

The General Plan amendment is consistent with Goal HE-2 of the Housing Element, to provide “Opportunities for well-designed and appropriate housing that is diverse in type, location, affordability, and tenure and that meets the full spectrum of current and future housing needs in San Dimas.” The amendment will allow for the development of four (4) more parcels than can currently be developed on the subject parcels based on the current land use, and the smaller lot size will provide more affordability than recent developments within the City.

Zone Change Findings
A. The proposed zone change will not adversely affect the adjoining property as to value, precedent or be detrimental to any area.

The proposed zone change does not change the primary permitted use of single-family residences or the development standards for any of the affected properties. No new uses will be allowed that could be detrimental to surrounding properties. The primary allowed use of singlefamily residences will be consistent with the surrounding neighborhoods and should have a negligible effect on the value nor be detrimental to adjoining properties.

B. The zone change will further the public health, safety and general welfare.

The amendment will create the ability to add seven (7) new single-family residences along Cherokee Court. These houses will provide more housing options within the City, furthering the general welfare of San Dimas residents. The new residences will create more ‘eyes on the street’ along Cherokee Court and help dissuade property crime in the area. For the parcels which are not a part of the subdivision, the amended Zoning will bring the parcels into alignment with the way in which they were developed and eliminate potential animal keeping, which the parcels were not designed to accommodate, protecting the health and welfare of surrounding neighbors.

C. The zone change is consistent with the General Plan and any applicable special plans.

The density which the zone change will allow is consistent with the proposed General Plan Land Use designation of Single Family Low. It also furthers Policy HE-2.1 of the Housing Element to “Provide opportunities for new housing that responds to community needs in terms of housing type, cost, and location by providing appropriate zoning and development standards” by allowing

RESOLUTION PC-1677 Page 6
for new, smaller lot residences that will provide residents with opportunities for new, more affordable housing within the City.

Development Plan Review Findings
A. The development of the site in accordance with the development plan is suitable for the use or development intended.

The Project consists of seven (7) new detached single-family homes, located on land that is currently zoned for single-family residences and is surrounded to the east, south and west by tracts of single-family homes. The proposed residences will maintain the feel and character of the surrounding neighborhoods. The development of the site is suitable for single-family residences, and the development has been designed to minimize any negative effects of the new homes on the surrounding neighborhoods.

B. The total development is so arranged as to avoid traffic congestion, ensure the public health, safety and general welfare, and prevent adverse effects on neighboring property.

The seven (7) new residences have been developed to avoid traffic congestion on East Gladstone Street by taking ingress and egress off of Cherokee Court, rather than causing traffic problems and potentially harming the health, safety and general welfare by taking ingress/egress off of West Gladstone Street, a busy thoroughfare. In addition, as a condition of the development, the Project will provide for new sidewalks along the west side of Cherokee Court, improving the neighborhood for all residents and providing safer conditions for both vehicular traffic and pedestrians.

C. The development is consistent with all elements of the general plan and is in compliance with all applicable provisions of the zoning code and other ordinances and regulations of the City.

The Project is consistent with the General Plan Housing Element Goals, Policy HE 2.3, which calls on the City to “Continue to encourage housing designs, site planning, landscaping, and architectural features consistent with the General Plan, design standards, and community context.” Staff has worked with the developer to provide high quality designs that fit within the architectural themes found within the community and San Dimas. The new residences are consistent with the proposed General Plan land use designation of Single Family Low and meet all applicable provisions of the San Dimas Municipal Code.

Tree Removal Findings
A. It is reasonable to remove the trees because the continued existence at the location prevents the reasonable development of the subject property.

The eleven protected trees that are proposed for removal prevent the reasonable development of the property. The majority of the trees are located along the eastern property line of the property and prevent the installation of the new City sidewalks. The remaining trees are in locations that conflict with the proposed locations for the future residences.

Therefore, removal of all eleven protected trees is warranted. As required by the City’s Tree Preservation ordinance, the Applicant will be required to plant a minimum of 22 replacement canopy-type trees as part of the approval. The approval will also require that 25% of the replacement trees must be 24” box in size and a minimum of three Oak trees to further mitigate the removal of the mature trees.

RESOLUTION PC-1677 Page 7
PURSUANT TO THE ABOVE FINDINGS, IT IS RESOLVED that the Planning Commission recommends to the City Council approval of Tentative Tract Map 22-0001 (TTM 83304), General Plan Amendment 23-0001, amending the land use designations as set forth on the Land Use Map in Exhibit “B”, Zone Change 22-0001,amending the zoning map as set forth on the Zoning Map in Exhibit “C”, Development Plan Review Board No. 22-0015 and Tree Removal Permit 22-0029, subject to the Applicant’s compliance with Conditions in “Exhibit A”, attached hereto and incorporated herein.

MITIGATION MEASURES

65. BIO-1. Nesting Bird Survey. Project activities, including initial vegetation trimming/clearing, tree trimming/removal, ground disturbance, and demolition, shall be avoided during the nesting season (January 1 to September 15). If the nesting season cannot be avoided, a nesting bird clearance survey is required within three (3) days prior to the start of Project activities during the nesting season. If active nests are present, avoidance of nest sites is required and a buffer of 300 to 500 feet (or as determined by a biologist) is recommended until a biologist has verified that juvenile birds are no longer dependent on the nest, or the nest has otherwise become inactive. An active nest is defined as a nest with eggs, chicks, or dependent juveniles, or a nest utilized for reproduction.

66. BIO-2. Pre-Construction Bat Survey. To the extent feasible, demolition or disturbance to suitable bat roosting habitat shall be scheduled between October 1 and February 28, outside of the maternity roosting season. If trees must be removed during the maternity season (March 1 to September 30), or if structures must be removed at any time of the year, a pre-construction survey by a qualified bat specialist is required within seven (7) days prior to disturbance. Maternity season lasts from March 1 to September 30 and trees or structures determined to be maternity roosts shall be left in place until the end of the maternity season.

Hibernating colonies shall be left in place until a qualified biologist determines that the bats are no longer hibernating. Bats shall be allowed to escape prior to demolition of structures.

This may be accomplished by placing one-way exclusionary devices into areas where bats are entering a structure that allows bats to exit but not re-enter.

67. CUL-1: Worker Environmental Awareness Program. Prior to the commencement of grading or excavation, workers conducting construction activities and their foremen will receive Worker Environmental Awareness Program (WEAP) training from a qualified archaeologist regarding the potential for sensitive archaeological and paleontological resources to be unearthed during grading activities. The workers will be directed to report any specimens of bone, stone, ceramics, or other archaeological artifacts or features observed during grading and/or other construction activities to their foremen and to cease grading activities in the immediate vicinity of the discovery until a qualified archaeologist and Native American cultural monitor is notified of the discovery and can assess their significance. The WEAP shall be implemented to educate all construction personnel of the area’s environmental conditions and the environmental protection measures that must be

RESOLUTION PC-1677 Page 16
adhered to by all workers throughout the duration of Project construction. Training materials shall be language-appropriate for all construction personnel. Upon completion of the WEAP, workers shall sign a form stating that they attended the program, understand all protection measures, and shall abide by all the rules of the WEAP. A record of all trained personnel shall be kept with the construction foreman at the Project field construction office and shall be made available to any resource agency personnel. If new construction personnel are added to the Project later, the construction foreman shall ensure that new personnel receive training before they start working. The archaeologist shall provide hard copies of the WEAP presentation to the construction foreman.

68. CUL-2: Archaeological Treatment Plan. If historical or unique archaeological resources are discovered during construction, the contractor shall halt construction activities in the immediate area and notify the City. A qualified archaeologist shall be notified and afforded the necessary time to recover, analyze, and curate the find(s). Additionally, any Native American Tribe who consulted on the Project as provided for in Public Resources Code §21080.3.1(b) (AB52), shall be contacted regarding any pre-contact finds and be provided information after the archaeologist makes his/her initial assessment of the nature of the discovery. The Tribe may provide input with regard to significance and treatment. A Monitoring and Treatment Plan shall be prepared by the qualified archaeologist. The qualified archaeologist shall recommend the extent of archaeological monitoring necessary to ensure the protection of any other resources that may be in the area and afforded the necessary time and funds to recover, analyze, and curate the find(s). Construction activities may continue on other parts of the site while evaluation and treatment of historical or unique archaeological resources takes place.

69. NOI-1. Grading Noise Reduction. The following notes shall be placed on the grading plan:
a. “The construction contractor will use the following source controls when working within 60 feet of occupied residential buildings:
i. Use of noise-producing equipment will be limited to the interval from 7:00 a.m. to 6:00 p.m. on weekdays, 8:00 a.m. to 5:00 p.m. on Saturdays, with no construction on Sundays.
ii. For all noise-producing equipment, use types and models that have the lowest horsepower and the lowest noise-generating potential practical for their intended use.
iii. The construction contractor will ensure that all construction equipment, fixed or mobile, is properly operating (tuned-up) and lubricated and that mufflers are working adequately.
iv. Have only necessary equipment onsite.
v. Use manually adjustable or ambient-sensitive backup alarms”.

70. TCR-1: Retain a Native American Monitor. Prior to Commencement of Ground-Disturbing Activities:
a. The project applicant shall retain a Native American Monitor from or approved by the Gabrieleño Band of Mission Indians – Kizh Nation. The monitor shall be retained prior to the commencement of any “ground-disturbing activity” for the subject project at all project locations (i.e., both on-site and any off-site locations that are included in the project description/definition and/or required in connection with the project, such as public improvement work). “Ground-disturbing activity” shall include, but is not limited to, demolition, pavement removal, potholing, auguring, grubbing, tree removal, boring, grading, excavation, drilling, and trenching.

RESOLUTION PC-1677 Page 17
b. A copy of the executed monitoring agreement shall be submitted to the lead agency prior to the commencement of any ground-disturbing activity, or the issuance of any permit necessary to commence a ground-disturbing activity. c. The Tribal 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 and to the lead agency.
d. Tribal monitoring shall conclude upon the following: (1) written confirmation to the Kizh from a designated point of contact for the project applicant or lead agency that all ground-disturbing activities and phases that may involve ground-disturbing activities on the project or in connection with the project are complete; or (2) a determination and written notification by the Kizh to the project applicant and lead agency that no future, planned construction activity and/or development/construction phase at the project site possesses the potential to impact TCRs.
e. Upon discovery of any TCRs, all construction activities in the immediate vicinity of the discovery shall cease (i.e., 50 feet) and shall not resume until the discovered TCR has been fully assessed by the Kizh monitor and the Kizh archaeologist. After any necessary assessment and analysis and reporting of the finds by the project archaeologist, the resources will be transferred to the Kizh for any purpose the Tribe deems appropriate, including for educational, cultural, and/or historical purposes.

71. TCR-2: Unanticipated Discovery of Human Remains and Associated Funerary Objects a. Native American human remains are defined in PRC §5097.98 (d)(1) as an inhumation or cremation in any state of decomposition or skeletal completeness.

Funerary objects, called associated grave goods in Public Resources Code §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 all construction activities in the vicinity of the discovery shall immediately cease. Health and Safety Code §7050.5 dictates that there shall be no further excavation of disturbance of the burial or any nearby area reasonably suspected overlie adjacent remains until the County Coroner has determined the nature of the remains. If the coroner recognizes the human remains to be those of a Native American or has reason to believe they are Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission and Public Resources Code §5097.98 shall be followed.
c. Human remains and grave/burial goods shall be treated alike per California Public Resources Code §5097.98(d)(1) and (2).
d. Construction activities may resume in other parts of the project site away from discovered human remains and/or burial goods. (CEQA Guidelines §15064.5(f).) e. Preservation in place (i.e., avoidance) is the preferred manner of treatment for discovered human remains and/or burial goods. Any historic archaeological material that is not Native American in origin (non-TCR) shall be curated at a

RESOLUTION PC-1677 Page 18
public, non-profit institution with a research interest in the materials, such as the Natural History Museum of Los Angeles County or the Fowler Museum, if such an institution agrees to accept the material. If no institution accepts the archaeological material, it shall be offered to a local school or historical society in the area for educational purposes.
f. Any discovery of human remains/burial goods shall be kept confidential to prevent further disturbance.

72. TCR-3: Procedures for Burials and Funerary Remains:
a. The term “human remains” encompasses more than human bones and includes the soil immediately surrounding the burial or cremation, the funerary objects placed with the deceased and ceremonial objects.
b. If the discovery of human remains includes four or more burials, the discovery location shall be evaluated as a cemetery and a separate treatment plan shall be created.
c. Associated funerary objects are objects that, as part of the death rite or ceremony of a culture, are reasonably believed to have been placed with individual human remains either at the time of death or later. Other items made exclusively for burial purposes or to contain human remains can also be considered as associated funerary objects.
d. In the case where discovered human remains cannot be fully documented and recovered on the same day, the remains will be covered with muslin cloth and a steel plate that can only be moved by heavy equipment will be placed over the excavation opening to protect the remains. If this type of steel plate is not available or suitable for use, a 24-hour guard should be posted outside of working hours until the remains can be suitably secured from disturbance. e. The Tribe will work with the project proponent (project applicant/developer and/or landowner) to recommend measures to keep the human remains in situ and protected in place. In the event that preservation in place is not possible, despite a good faith effort by the project proponent, before ground-disturbing activities may resume in the immediate area, the landowner will designate a reburial /repatriation site. This location will be agreed upon by the Tribe and the landowner and shall be protected in perpetuity. There shall be no publicity regarding any cultural materials, human remains, or associated funerary objects. f. Any human remains and associated funerary objects that are moved from a burial location will be placed into opaque cloth bags together with any associated funerary objects, sacred objects, and objects of cultural patrimony. The bags will be secured in a container on site or in a location agreed upon by the Tribe and the project proponent. All recovered remains will be reburied within six months of recovery.
g. The Tribe will work closely with the project’s qualified archaeologist to ensure any excavation is treated carefully, ethically, and respectfully. If reburial involves data recovery approved by the Tribe, documentation shall include (at a minimum) detailed descriptive notes and sketches. All data recovery documentation related to the human remains or associated burial goods shall be approved in advance by the Tribe. If any data recovery is performed by the project archaeologist, once analysis is complete, a final report shall be written and submitted to the Tribe and the NAHC. Unless expressly agreed to by the Kizh, the Tribe does NOT authorize any scientific study or the utilization of any invasive and/or destructive diagnostics on human remains.

WHEREAS, failure to adopt Resolution PC-1676 constitutes a denial for the Proposed Project as all other associated applications cannot be approved without the adoption of the Mitigated Negative Declaration and Mitigation Monitoring and Reporting Program.

NOW, THEREFORE, in consideration of the evidence received at its hearings on April 18, 2024, and for the reasons discussed by the Commissioners at the hearing, and subject to the Conditions attached as “Exhibit A” to Resolution PC-1676, the Planning Commission now finds as follows:

A. The above recitals are true and correct and are incorporated herein by this reference.

B. All actions required to be taken by applicable law related to the preparation circulation, and review of the MND have been taken.

C. A Mitigated Negative Declaration has been prepared consisting of the Initial Study, all comments and recommendations received during the public review period, and a Mitigation and Reporting Program. The MND was posted on the City’s Website at www.cityofsandimas.com on February 19, 2024. On the basis of the Initial Study prepared for the Proposed Project it has been determined that the Proposed Project may have a potential significant effect on the environment which, however, will be mitigated to a level that is less than significant and therefore, a Mitigated Negative Declaration was circulated for a period of not less than 30 days pursuant to State CEQA Guidelines Section 15105(b). Therefore the Planning Commission finds the Mitigated Negative Declaration as adequate to assess the environmental impacts of the Proposed Project, based on the findings contained herein and in the Mitigated Negative Declaration, and finds, on the basis of the whole record that there is no substantial evidence that the Proposed Project will have a significant

effect on the environment and that the recommended adoption of the Mitigated Negative Declaration reflects the City of San Dimas Planning Commission’s independent judgment and analysis.

D. The Planning Commission further recommends the City Council adopt the Mitigated Negative Declaration and the Mitigation Monitoring and Reporting Program (attached hereto as Exhibit A), as this Proposed Project would not result in any significant, adverse environmental impacts with the mitigation imposed. The full record is available for review in the Planning Division.

NOW, THEREFORE, BE IT FURTHER RESOLVED, PURSUANT TO THE ABOVE FINDINGS, that:

SECTION 1. The Initial Study/Mitigated Negative Declaration is adequate to assess the environmental impacts of the Proposed Project, based on the findings contained herein and in the Mitigated Negative Declaration, and, on the basis of the whole record, there is no substantial evidence that the Proposed Project will have a significant effect on the environment. This determination reflects the City of San Dimas Planning Commission’s independent judgment and analysis.

SECTION 2. The Planning Commission recommends to the City Council adoption and approval of the Initial Study/Mitigated Negative Declaration and the Mitigation Monitoring and Reporting Program as set forth in “Exhibit A” attached hereto and incorporated herein, and that the decision shall be final unless a timely appeal is filed with the City Council. A copy of this Resolution shall be mailed to the Applicant/Property Owner.

The Planning Commission recommends that the City Council direct the Director of Community Development, located at the Community Development Department, 245 E.

Bonita Ave., San Dimas, CA 91773, to serve as the custodian of all documents or other material which constitutes the record of proceedings upon which the Council's adoption of the Mitigated Negative Declaration would be based. The Planning Commission further recommends that the City Council authorize and direct the Director of Community Development, or designee, to execute and file with the Los Angeles County Clerk, within five business days of the adoption of a resolution approving the Mitigated Negative Declaration, a Notice of Determination that complies with CEQA Guidelines, section 15075.

Re: Tentative Tract Number 83304
Cherokee Court
San Dimas, Ca.

Dear Stan,
I am writing as a follow-up to my January 31, 2022, on-site inspection of the trees within the subject tentative tract location within the city of San Dimas, California.

Assignment
Travel to the site, review the existing trees, and prepare an inventory of the individual trees that meet or approach meeting the city of San Dimas’ size standards to be considered Mature Significant Trees. Prepare ‘Excel’ spreadsheet and ‘Word’ document executive summary of the spreadsheet.

Observations
There are a total of 22 individual trees that are included in the attached ‘Excel’ spreadsheet inventory. Of these one is off-site (No.1), one is dead (NO.15), nine individuals do not meet the minimum size criteria to be considered Mature Significant Trees, and eleven are Mature Significant Trees by their status as oaks that are greater than eight inches in diameter, non-oaks that are minimum of ten inches in diameter, and multi trunk trees that are a combined 38 inches in diameter with at least one trunk that is four inches in diameter or larger. All trunk diameter measurements are at 36” height above the soil level as established by the city’s tree ordinance.

The eleven mature significant trees are scheduled for removal to allow for the site engineering and improvements including widening Cherokee Court. Tree numbers 11, 12, 16, 18, and 20 are oaks that are mature significant trees that are among the proposed removals. The other six Mature Significant Trees scheduled for removal are all nonnative species, Xylosma, Tillea, Chorissia, Liquidambar, and Carya.

____________________________________________________________________________

SUMMARY
The Applicant, Ignacio Crespo of OC Design & Engineering, on behalf of Allen Industrial Investors LLC, is requesting approval of a Zone Change to change the zoning land use designation from Light Agriculture (AL) to Light Manufacturing (M-1), a Lot Merger to consolidate three (3) contiguous lots, a Development Plan Review Board application for a 63,749 square-foot concrete tilt-up warehouse/office multi-tenant building, and a Tree Removal Permit to remove 17 mature trees in conjunction with the project located on a 2.58 acre site located at the northwest corner of Allen Avenue and Cataract Avenue.

On March 23, 2023, the Development Plan Review board, at a regularly scheduled meeting, recommended approval to the Planning Commission of DPRB 21-0002 and TRP 21-0004 for the design and construction of the tilt-up warehouse/office multi-tenant building along with the associated removal of 17 mature trees.

On May 4, 2023, the Planning Commission, at a regularly scheduled meeting, voted 4-1 to recommend to the City Council approval of Zone Change 21-0001 for the change of zoning from Light Agricultural to Light Manufacturing, Lot Merger 21-0001 for the merger of three contiguous lots, Development Plan Review Board 21-0002 for the design and construction of the tilt-up warehouse/office multi-tenant building, and Tree Removal Permit 21-0004 for the associated removal of 17 mature trees, along with recommending adoption of the associated Initial Study/Mitigated Negative Declaration.

ZC 21-0001, LM 21-0001, DPRB No. 21-0002, & TRP21-0003 Page 2 For the Meeting of May 14, 2024

RECOMMENDATION
Staff and the Planning Commission recommend that the City Council:

1. Adopt Resolution 2024-28, approving the Initial Study/Mitigated Negative Declaration.

2. Introduce Ordinance 1306, approving Zone Change 21-0001, changing the zoning designation of the parcels from Light Agriculture (AL) to Light Manufacturing (M-1).

3. Adopt Resolution 2024-27, approving Lot Merger 21-0001, the merger of three contiguous lots; and as recommended by Development Plan Review Board DPRB Case No. 21-0002 design and construction of the tilt-up warehouse/office multi-tenant building and Tree Removal Permit 21-0004 for the removal of 17 mature trees, with the adoption of the associated Initial Study/Mitigated Negative.

FISCAL IMPACT
There is no fiscal impact for the recommended action. All costs associated with the cost to prepare the Initial Study/Mitigated Negative Declaration (IS/MND) for the project were borne by the Applicant.

BACKGROUND
On November 24, 2020, City Council authorized the initiation of a Zone Change from Light Agriculture (A-L) to Light Manufacturing (M-1) to allow the Applicant, Ignacio Crespo, O.C.

Engineering & Design, on behalf of the property owner, Allen Industrial Investors LLC to submit entitlement applications to develop a 2.58-acre site comprised of three (3) contiguous parcels that are currently developed with nine (9) single-family homes into a warehouse building.

On January 25, 2021, the Applicant submitted the following applications for the development of the warehouse project:

1. Zone Change No. 21-0001 – A request to change the zoning land use classification from Light Agriculture (AL) to Light Manufacturing (M-1).

2. Lot Merger 21-0001 – A request to consolidate three (3) contiguous lots together.

3. DPRB Case No. 21-0002 – A request for development of a 63,749 square-foot concrete tilt-up warehouse/office multi-tenant building.

4. Tree Removal Permit No. 21-0004 – A request to remove 17 mature trees in conjunction with the project.

The 2.58-acre subject site consists of three (3) contiguous lots, which will be merged as part of the development process and was developed with nine (9) vacant single-family residences (See Figure 1). Typically, existing structures are not demolished until after the project has received all approvals and building permits have been issued. However, since the homes were vacant, there was several issues related to people occupying the vacant structures that resulted in several responses by the Sheriff’s Department. Therefore, a demolition permit was issued on March 13, 2023, to address the health and safety issues and concerns that have resulted from the structures being vacant. No other activity, including removal of trees, will occur until after the project has been approved and all permits have been issued.

ZC 21-0001, LM 21-0001, DPRB No. 21-0002, & TRP21-0003 Page 3 For the Meeting of May 14, 2024
At its March 23, 2023, regular meeting, the Development Plan Review board (DPRB) considered DPRB No. 21-0002 and TRP 21-0004 for the design and construction of the tilt-up warehouse/office multi-tenant building along with the associated removal of 17 mature trees. After consideration, the DPRB recommended approval of the two (2) applications to the Planning Commission, subject to the recommended Conditions of Approval. The DPRB did not act on the Zone Change or Lot Merger, as the actions are not under DPRB purview.

At the May 4, 2023, regular meeting, the Planning Commission considered the project applications, along with the associated Initial Study/Mitigated Negative Declaration. The Commission raised concerns with the height (41 feet) of the warehouse building and with the heavy truck traffic that could result from the new warehouse use. In addition, during the public comment period, two (2) residents raised concerns with traffic and noise associated with the trucks for the proposed warehouse use, and concerns that employees would park on the street.

After conducting a public hearing, the Planning Commission voted 4-1 to recommend approval of all project and the IS/MND to the City Council, with an added condition that no truck ingress or egress shall be allowed on the Allen Avenue driveway. Chairman Bratt voted against the project citing concerns with the height of the building and increased traffic. See Attachment 5 for the Commission staff report, the resolutions and minutes.

DISCUSSION/ANALYSIS
Zone Change and Lot Merger
The Applicant is requesting approval of a Zone Change from the existing zoning of Light Agriculture (A-L) to Light Manufacturing (M-1). The proposed Zone Change consists of three (3) contiguous parcels all of which are owned by the same owner. The Applicant is also requesting Figure 1 – Aerial Map

ZC 21-0001, LM 21-0001, DPRB No. 21-0002, & TRP21-0003 Page 4 For the Meeting of May 14, 2024
approval of a Lot Merger to consolidate the three (3) contiguous lots together in order to complete the project. The proposed 2.58-acre lot will meet the minimum lot size requirement of 10,000 square feet and the minimum lot dept of 100 feet as required by the proposed M-1 Zone. The Zoning and General Plan designations for the site and surrounding areas are shown in the following maps (Figure 2) and Table 1 below.

ZC 21-0001, LM 21-0001, DPRB No. 21-0002, & TRP21-0003 Page 5 For the Meeting of May 14, 2024
The site is surrounded by developed single-family residences to the south and developed light industrial buildings to the north, east, and west. The proposed zone change will bring the site into compliance with the General Plan Land Use designation of Industrial and will integrate the parcel to the surrounding industrial zoning thereby making it consistent with the adjacent buildings and uses.

The existing AL land use classification allows for one single-family residential unit per lot. The subject lots are considered to be non-conforming lots due to the fact that they were developed with nine (9) single-family residences; six (6) more than what is currently allowed in the AL zone.

By changing the current zone of AL to M-1, which does not allow residential uses, there will be a net loss of three (3) residential units in the City. Pursuant to Government Code Section 66300, as amended by Senate Bill (SB) 8 in 2021, the zone change from AL to M-1 cannot occur unless another property is rezoned to increase the residential density in the City by at least three (3) units, one per parcel that were allowed under the AL zoning. Furthermore, the final action to approve the rezoning must occur concurrently at the same meeting of the legislative body, in this case, the City Council. The Commission can recommend approval to the City Council of the zone change for the project before them, but the City Council will need to consider another property to upzone residential density at the same meeting. Staff is processing an application for a sevenunit residential subdivision which meets the no net loss criteria and is being considered at this same meeting.

Site Description/Improvements
The proposed building will be located at the southeast corner of the site, and a new drive aisle with parking will wrap around the building along the west and north property lines and will be accessed from Allen Avenue and Cataract Street. A truck loading dock will be located along the west elevation of the building and will service both proposed units within the new warehouse building, and a trash enclosure will also be constructed adjacent to the drive aisle along the west property line. A new ten-foot-high concrete tilt up screen wall to match the building finish, and an eight-foot-high wrought iron sliding gate will be installed at two (2) locations to secure the parking lot. The first one will be located approximately 86 feet north of the Allen Avenue driveway entrance, and the second one will be located in approximately 253 feet west of the Cataract Avenue driveway entrance. There is an existing masonry wall that is shared with the adjacent lots to the west (327 W. Allen Avenue) and north (949 N. Cataract Avenue); therefore, no new perimeter walls will be incorporated into the project. The existing walls will be required to be finished to match the proposed building finish. All site lighting will be required to install fixtures that direct light downward and does not spillover onto adjacent properties. In addition, as part of the project, the Applicant will be required to install a new sidewalk along their Cataract Avenue frontage and will be required to underground all existing overhead utility lines that are located along the project frontages.

The project requires a total of 54 parking spaces and four (4) motorcycle spaces, and the project is proposing 56 parking spaces and four (4) motorcycle spaces in compliance with the Code requirement. As previously mentioned, the project will be accessed via two (2) driveways located on Allen Avenue and Cataract Avenue. In an effort to reduce impacts to Allen Avenue, Condition of approval No. 72 has been included to require that truck ingress be limited to the Cataract Avenue driveway and that the Applicant also install signing and striping improvements to prevent truck ingress from Allen Avenue. Lastly, the project will provide a bicycle rack near the entrance to each unit, with each rack securing up to five (5) bicycles.
