Construction
Construction activity can cause varying degrees of ground vibration, depending on the equipment and methods used, the distance to receptors, and soil type. Construction vibrations are intermittent, localized intrusions. The use of heavy construction equipment, particularly large bulldozers, and large loaded trucks hauling materials to or from the site generate construction-period vibration impacts.
The Noise and Vibration Impact Analysis (Appendix G) uses vibration standards in the FTA Manual to analyze ground-borne vibration impacts on human annoyance. The Analysis discusses the level of human annoyance using vibration levels in VdB and assesses the potential for building damages using vibration levels in PPV (in/sec). Vibration levels calculated in VdB are best for characterizing human response to building vibration, while vibration level in PPV is best for characterizing potential for damage. The FTA guidelines indicated that for a non-engineered timber and masonry building, the construction vibration damage criterion is 0.2 in/sec in PPV. The threshold at which vibration levels would result in annoyance would be 78 VdB for daytime residential uses. Table N-6 shows the PPV and VdB values at 25 feet from the construction vibration source.
Table N-6: Vibration Source Amplitudes for Construction Equipment Equipment Reference PPV/Lv at 25 ft

1 RMS vibration velocity in decibels (VdB) is 1 μin/sec. μin/sec = microinches per second; ft = foot/feet; in/sec = inch/inches per second; LV = velocity in decibels; PPV = peak particle velocity; VdB = vibration velocity decibels
Source: Noise and Vibration Impact Analysis (Appendix G) Table N-7 shows the summary of vibration annoyance levels due to construction equipment to the closest structure to the Project site. The distance to the nearest building for vibration impact analysis is measured between the nearest off-site buildings and the Project construction boundary. Using the following formula, the Noise and Vibration Impact Analysis calculated anticipated vibration levels at the nearest structure and sensitive receptors.
LvdB (D) = LvdB (25 feet) – 30 Log (D/25)
PPVequip = PPVref x (25/D)1.5
The closest structure to the Project site is the residential use located approximately 33 feet from the limits of construction disturbance. At a distance of 33 feet, the structure would experience vibration levels of 0.059 PPV (in/sec) from the use of heavy equipment at the limits of construction disturbance. Therefore, vibration levels experienced at the closest structure to the limits of construction disturbance would not exceed the 0.2 PPC (in/sec) damage threshold. Vibration levels at all other structures near the Project site would be lower Mitigated Negative Declaration
City of Glendora North Glendora Reservoir Replacement Project 134
due to increases in distance. Therefore, construction would result in a less than significant impact related to vibration damage.
The existing residential use to the southwest of the Project site is the nearest sensitive receptor at approximately 150 feet from the center of the Project site. The Noise and Vibration Impact Analysis estimates the nearest residence would experience vibration levels approaching 64 VdB, which is below the threshold of 78 VdB for residential uses during the day. Therefore, Project construction would not result in vibration levels that would typically result in human annoyance. Impacts would be less than significant.
Operation
Once operational, the Project would not be a significant source of groundborne vibration. Groundborne vibration surrounding the Project currently result from heavy-duty vehicular travel (e.g., refuse trucks, heavy duty trucks, delivery trucks, and transit buses) on the nearby local roadways. Operations of the Project would not involve heavy duty trucks but would involve weekly maintenance vehicles visiting the site. Due to the rapid drop-off rate of ground-borne vibration and the short duration of the associated events, vehicular traffic-induced ground-borne vibration is rarely perceptible beyond the roadway right-of-way, and rarely results in vibration levels that cause damage to buildings in the vicinity. Additionally, since the use of the Project would not change with implementation of the proposed Project, maintenance trips associated with operation of the proposed reservoirs would not increase beyond those that are already occurring. Therefore, the Project would result in less than significant impacts related to ground born vibration. c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? Less Than Significant Impact. The proposed Project site is located approximately 6.37 miles northwest of Brackett Airfield and is outside the boundaries of the Bracket Field Airport Land Use Compatibility Plan and thus is located outside of the 60 dBA CNEL noise contours of Brackett Airfield (Los Angeles Airport Land Use Commission 2015). Therefore, the proposed Project would not expose people residing or working in the Project area to excessive noise levels from airports. Impacts would be less than significant.

a) Induce substantial unplanned population growth in an area, either directly or indirectly? Less Than Significant Impact. The proposed Project would demolish an existing reservoir and construct two new reservoirs. The Project would not create permanent jobs but would require a temporary minimal labor force during construction. These construction workers are anticipated to come from the local workforce within the region. Additionally, although the Project is adding a second water reservoir to the site, the second reservoir would be utilized for reliability purposes and would not induce growth. Therefore, impacts related to unplanned population growth from the Project would be less than significant. b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?
No Impact. There is no housing on the Project site and implementation of the Project would not displace any existing numbers of people. Thus, no impact would occur.

Other public facilities?
a) Fire Protection and Emergency Services
b) Police Protection
c) School Services
d) Parks
e) Other Public Facilities
Less Than Significant Impact. Construction of the proposed water tanks would not create significant additional demand for, or alteration of, government facilities or services (including fire and emergency services, police protection, schools, parks, or other public facilities). The Project would facilitate the provision of water and fire protection in the water service area by replacing a failing water reservoir with two new reservoirs. The proposed Project would not result in an increase in the City’s population and the site would be used for the same purposes as existing conditions. It should also be noted that the City’s budget to fund the Project would include funding for the operation and maintenance of the facility.
The Los Angeles County Fire Department already provides fire suppression and emergency medical services to the site and surrounding area and would continue to provide these services with implementation of the Project. The closest fire station to the Project site is Los Angeles County Fire Dept. Station 151, located approximately 1.25 miles south of the site. Additionally, the Glendora Police Department already provides police services to the site and surrounding area and would continue to provide these services with Mitigated Negative Declaration

implementation of the Project. The Glendora Police Department is located approximately 1.5 miles south of the Project site.
During Project construction, there could be occasional calls for fire protection, emergency services, or police protection, in the cases of medical emergency or construction equipment theft. However, because these calls for service would be temporary, if they occur, and because the site would not be occupied at Project completion such that calls for service are generated, impacts would be less than significant.
Additionally, reservoir B would be online during the construction of reservoir NGR-A, thus, adequate fire protection would be available to the area if needed. Overall, impacts related to public services would be less than significant.

a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that physical deterioration of the facility would be accelerated? No Impact. The proposed Project involves the demolishing of an existing water reservoir, the construction of two new reservoirs within the same Project site and associated onsite pipeline improvements. The proposed Project would not increase population or housing in the area, which drives the demand for recreational facilities. Therefore, there would not be an increased demand for recreational facilities and no physical deterioration of existing recreational facilities in the area would occur. b) Require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment?
No Impact. As stated above, the proposed Project involves the demolishing of an existing water reservoir, the construction of two new reservoirs within the same Project site and associated onsite pipeline improvements. The Project would not construct any residential facilities, nor create an additional need for housing. The Project would not directly increase the residential population of the City or generate additional need for parkland. The Project does not include or require the construction or expansion of recreational facilities which could negatively impact the environment, and no offsite parks or recreational improvements are proposed or required as part of the Project. Thus, no impacts would occur.

Less Than Significant Impact.
Construction.
The Project site would replace the existing reservoir with two new reservoirs. The existing use on the site would not change upon Project implementation. Construction activities associated with the Project would generate vehicular trips from construction workers traveling to and from the Project site, delivery of construction supplies and import materials to, and export of debris from, the Project site. However, these construction activities would be temporary in nature and only occur during the anticipated 22-month construction period. Additionally, all construction equipment would be staged within the construction staging area as shown on Figure 3-1, Conceptual Site Plan, which would eliminate the need for daily transport of equipment through the surrounding residential area. Further, Project construction would not require any lane closures and all construction work would occur off public roadways. Impacts related to a temporary increase in traffic due to construction would be less than significant.
Operation
Operation of the Project is not expected to generate any additional trips. Since the use of the site would not change with implementation of the Project, the existing routine maintenance trips would not increase with operation of the new reservoirs. Impacts related to operational trips would be less than significant.
Alternative Transportation
The Project is not anticipated to generate pedestrian or bicycle traffic or transit usage due to the nature of the Project and the isolated location. The Project would not conflict with alternative transportation and Project impacts to transit, bicycle, and pedestrian facilities would be less than significant. b) Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)?
No Impact. Senate Bill (SB) 743 was signed by Governor Brown in 2013 and required the Governor’s Office of Planning and Research (OPR) to amend the State CEQA Guidelines to provide an alternative to LOS for Mitigated Negative Declaration
City of Glendora North Glendora Reservoir Replacement Project 140
evaluating transportation impacts. SB743 specified that the new criteria should promote the reduction of GHGs, the development of multimodal transportation networks and a diversity of land uses. In response, Section 15064.3 was added to the CEQA Guidelines beginning January 1, 2019. Section 15064.3(c) states that the provisions of the section shall apply statewide beginning on July 1, 2020. State CEQA Guidelines Section 15064.3 - Determining the Significance of Transportation Impacts states that VMT is the most appropriate measure of transportation impacts and provides lead agencies with the discretion to choose the most appropriate methodology and thresholds for evaluating VMT.
The Project would replace an existing water reservoir with two new reservoirs. The Project would not change the use of the site and the use is not a traffic generating land use. The Project would require a maintenance vehicle to travel to the site on an approximately weekly basis. However, trips required during operation would be negligible and would not increase vehicle miles traveled. For the reasons above, the Project would not conflict or be inconsistent with CEQA transportation guidelines and no impacts related to CEQA Guidelines Section 15064.3, Subdivision (b) would occur c) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Less Than Significant Impact. Access to the site would be improved by widening the existing access road off North Glendora Avenue to increase safety of maintenance vehicle access to the site. Additionally, prior to demolition and construction of the reservoirs, North Glendora Avenue or Easley Canyon Road would be improved and widened in order to adequately handle construction equipment and vehicles travelling to the site. Compliance with existing regulations would be ensured through the City’s development permitting process. The proposed Project would not substantially increase hazards due to a design feature or incompatible uses. Therefore, there would be a less than significant impact related to increased hazards, and no mitigation measures would be required.
d) Result in inadequate emergency access?
Less Than Significant Impact.
Construction
The proposed construction activities, including equipment and supply staging and storage, would occur within the Project site which includes an approximately 0.25-acre staging area located 150 feet southwest of the existing reservoir pad (see Figure 3-1, Conceptual Site Plan), and would not restrict access of emergency vehicles to the Project site or adjacent areas. The widening of the offsite construction access route, existing reservoir access road, and connections to existing infrastructure systems that would be implemented during construction of the proposed Project could require the temporary closure of one side or portions of North Glendora Avenue and/or Easley Canyon Road for a short period of time (i.e., hours or a few days).
However, the construction activities would be required to ensure emergency access in accordance with Section 503 of the California Fire Code (Title 24, California Code of Regulations, Part 9), which would be ensured through the City’s permitting process. Thus, implementation of the Project through the City’s permitting process would ensure existing regulations are adhered to and would reduce potential construction related emergency access impacts to a less than significant level.
Operation
As described previously, the proposed Project site would be accessed on a weekly basis for maintenance purposes from North Glendora Road. Once in operation, the proposed reservoirs would not result in inadequate emergency access at the Project site or in the local vicinity. Impacts would be less than significant.

Less than Significant with Mitigation Incorporated. The Project is required to comply with AB 52 regarding tribal consultation. Chapter 532, Statutes of 2014 (i.e., AB 52), requires that Lead Agencies evaluate a project’s potential to impact “tribal cultural resources.” Such resources include sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are eligible for inclusion in the California Register or included in a local register of historical resources (PRC Section 21074). AB 52 also gives Lead Agencies the discretion to determine, supported by substantial evidence, whether a resource falling outside the definition stated above nonetheless qualifies as a “tribal cultural resource.” Also, per AB 52 (specifically PRC 21080.3.1), Native American consultation is required upon request by a California Native American tribe that has previously requested that the City provide it with notice of such projects.
An archaeological records search was completed in order to identify any previously recorded archaeological sites within the Project boundary or in the immediate vicinity. According to the records search three resources were identified within a one-mile radius, none of which are located on the Project site.
Additionally, on August 24, 2022, Brian F. Smith and Associates requested a SLF search from the NAHC. On September 29, 2022, the NAHC responded that the SLF search yielded positive results for known tribal Mitigated Negative Declaration

cultural resources or sacred lands within a one-mile radius of the Project site. Pursuant to the requirements of AB 52, on April 4, 2023, the City sent informational letters about the proposed Project and requests for consultation to the tribes who may have traditional and cultural affiliation with the Project site. The City received responses from the following tribes:
• Fort Yuma Quechan Indian Tribe responded on April 12, 2023, and stated they do not have comments on the Project and defer to more local tribes. • Yuhaaviatam of San Manuel Nation (YSMN) (formerly known as the San Manuel Band of Mission Indians) responded on May 1, 2023, and stated they do not have concerns with the Project’s implementation. YSMN provided mitigation measures to be incorporated into the Project. • Gabrieleño Band of Mission Indians - Kizh Nation responded on April 17, 2023, requesting consultation. Consultation occurred on May 10, 2023, where Gabrieleño provided local tribal knowledge of the Project area and provided mitigation measures to be incorporated into the Project.
Mitigation Measures TCR-1, TCR-2, TCR-3, and TCR-4 have been included to require both YSMN and Gabrieleño Band of Mission Indians-Kizh Nation to be contacted in the event of a tribal cultural resource discovery. Coordination with both tribes on potential tribal cultural resource discoveries and would ensure proper precaution and handling of such resources, and further, minimize potential impacts to resources.
Therefore, with implementation of Mitigation Measures TCR-1, TCR-2, TCR-3, and TCR-4, impacts to tribal cultural resources would be less than significant.
b) Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is a resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision include of Public Resources Code Section 5024.1. In applying the criteria set forth in subdivisiinclude(c) of Public Resources Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.
Less Than Significant Impact with Mitigation Incorporated. As discussed above, to avoid potential adverse effects to tribal cultural resources, Mitigation Measures CUL-1, TCR-1, TCR-2, TCR-3 and TCR-4 have been included to require coordination with YSMN and Gabrieleño Band of Mission Indians-Kizh Nation to avoid potential impacts to tribal cultural resources that may be unearthed by Project construction activities. During consultation, Gabrieleño Band of Mission Indians – Kizh Nation provided information to the Lead Agency indicating the potential of uncovering tribal cultural resources on the Project site. However, with implementation of Mitigation Measures CUL-1, TCR-1, TCR-2, TCR-3 and TCR-4, impacts related to these potentially discovered resources would be reduced to less than significant.
Additionally, as described previously California Health and Safety Code, Section 7050.5, included as PPP CUL-1, requires that if human remains are discovered in the Project site, disturbance of the site shall halt and remain halted until the coroner has conducted an investigation. If the coroner determines that the remains are those of a Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission. Therefore, with implementation of Mitigation Measures TCR-1, TCR-2 and Mitigation Measure CUL-1, impacts to TCRs would be less than significant.

Water Infrastructure
The Project site is currently served by City of Glendora Water Division’s water infrastructure. The Project proposes the replacement of one water reservoir with two new reservoirs which would increase the overall reliability of the City’s existing water system. During construction, the existing reservoir would be kept online and operational to provide water service to the surrounding community. The proposed reservoirs would tie into to the City’s water system via a proposed 12-inch water line that would be constructed within the access road. The proposed 12-inch waterline would then be connected to the existing 8-inch waterline in North Glendora Avenue (see Figure 3-1, Conceptual Site Plan).
No expansion of the water pipelines that convey water to the surrounding community would be required.
Installation of the new water distribution lines would only serve the proposed Project and would not provide new water supplies to any off-site areas.
Mitigated Negative Declaration
City of Glendora North Glendora Reservoir Replacement Project 146
The construction activities related to the onsite water infrastructure that would be needed to serve the proposed Project is included as part of the Project and would not result in any physical environmental effects beyond those identified throughout this IS/MND. For example, analysis of construction emissions from excavation and installation of the water infrastructure is included in Sections 3, Air Quality and 8, Greenhouse Gas Emissions. Therefore, the proposed Project would not result in the construction of new water facilities or expansion of existing facilities, the construction of which could cause significant environmental effects, and impacts would be less than significant.
Wastewater
Similar to existing conditions, the proposed Project would not utilize wastewater services. Therefore, the Project would not require or result in the construction of new or expanded wastewater treatment facilities.
Storm Drainage
Site runoff would be collected in grated inlets and would flow into a 12-inch diameter PVC drainpipe, which would outlet the existing grouted riprap outlet on the east side of the site. Due to the appropriate sizing of the onsite drainage features, as ensured through the Project permitting process, operation of the proposed Project would not substantially increase stormwater runoff, and the Project would not require or result in the construction of new offsite storm water drainage facilities or expansion of existing offsite facilities, the construction of which could cause significant environmental effects. The required installation of the proposed drainage features is included as part of the proposed Project and would not result in any physical environmental effects beyond those identified in other sections of this IS/MND. Overall, impacts related to stormwater drainage facilities would be less than significant.
Electric Power
The Project would connect to the existing Southern California Edison facilities adjacent to the Project site.
Electric service for the Project would be obtained from the existing single phase pole mounted meter south of the reservoir site which would be relocated to the southwest corner of the improved pad. The meter would provide power to tank mixers, site lighting, security camera system, instrumentation, intrusion alarms, PLC, SCADA system, and the gate controller. Additionally, a 10kW diesel generator and an automatic transfer switch would be included to provide power during outages of the Southern California Edison system. The Project would not require the construction of new electrical facilities. Overall, impacts related to electric power would be less than significant.
Natural Gas
The Project would not utilize natural gas. Therefore, the Project would not require or result in the construction of new or expanded natural gas facilities.
Telecommunications
Data and alarms from the site would be transmitted to the City’s central SCADA system through radio communication. The Project would not require the construction of new telecommunications facilities. b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry, and multiple dry years? No Impact. The proposed Project would improve the City’s water supply system by replacing a failing water reservoir with two new reservoirs. No water supply is necessary to serve the Project because the Project itself would not involve the increase of population or consumption of water. Therefore, there would be no impact with regard to having sufficient water supplies to serve the proposed Project. c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
Mitigated Negative Declaration
City of Glendora North Glendora Reservoir Replacement Project 147
No Impact. As with existing conditions, the proposed reservoirs would not generate wastewater and would not demand any wastewater treatment capacity. Therefore, there would be no impact. d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? Less Than Significant Impact. Athens Services provides solid waste collection and recycling services to the City of Glendora. The refuse is collected and hauled to Athens Material Recovery Facility in the City of Industry. Prior to being transported to the landfill, the waste is processed to separate recyclables from the waste stream.
The City’s Municipal Code Section 6.09, Construction and Demolition Waste Management, outlines requirements for certain covered projects to divert a minimum of 50 present by weight of construction and demolition debris resulting from that project. Section 6.09.030, Threshold for covered projects, indicates that City-sponsored projects, such as the proposed Project, are considered covered projects and therefore must comply with the provisions of Section 6.09. The Project would be required to submit a waste management plan to explain how the developer would recycle a minimum of 50 percent of all waste materials generated by the Project. The developer must provide evidence of compliance with the approved waste management plan at Project completion. The provisions of Municipal Code Section 6.09 have been incorporated into the Project as PPP U-1.
Construction
The proposed Project involves demolition of an existing reservoir and construction of two new reservoirs.
Demolition of the proposed Project is expected to result in approximately 2,538.5 tons of debris (Appendix A). According to the City of Glendora 2006 General Plan Initial Study, solid waste in the City would be disposed of at the Puente Hills Landfill, the Mesquite Regional Landfill or the Eagle Mountain Landfill.
However, upon further research, it was found that all of those landfills have either been permanently closed or are currently inactive.
The next closest landfill to the Project site is Scholl Canyon Landfill in the City of Glendale. The Scholl Canyon Landfill is permitted to accept 3,400 tons of solid waste per day and has a remaining capacity of 9,900,000 tons. As of March 2023, the landfill accepted approximately 1,257.8 tons of solid waste per day. Thus, the daily remaining capacity is approximately 2,242.2 tons per day. Since the Project would be required to recycle a minimum of 50 percent of the Project’s construction and demolition debris, the remaining solid waste in need of disposal would be easily accommodated by Scholl Canyon Landfill.
Therefore, compliance with the City's Municipal Code requirements and with all federal, State, and local regulations related to solid waste, the Project would not generate solid waste in excess of State and local standards. Impacts would be less than significant.
Operation
Similar to existing conditions, operation of the new reservoirs would not generate solid waste. No significant impacts would occur, and no mitigation is required.
e) Comply with federal, state, and local statutes and regulations related to solid waste? Less Than Significant Impact. The proposed Project would result in temporary demolition and construction activities that would generate an increased amount of solid waste. All solid waste-generating activities within the City are subject to the requirements set forth in Section 5.408.1 of the 2022 California Green Building Standards Code that requires demolition and construction activities to recycle or reuse a minimum of 65 percent of the nonhazardous construction and demolition waste.
In addition, as stated in Response 5.19(d) above, the Project would be required to comply with the City’s Municipal Code Section 6.09, Construction and Demolition Waste Management, which requires that City- Mitigated Negative Declaration
City of Glendora North Glendora Reservoir Replacement Project 148
sponsored projects prepare a waste management plan indicating how the project developer would divert a minimum of fifty percent by weight of the construction and demolition debris resulting from the project. In addition, the proposed Project would be required to comply with all federal, State, and local regulations related to solid waste. Therefore, the proposed Project is anticipated to result in less than significant impacts related to potential conflicts with federal, State, and local management and reduction statutes and regulations pertaining to solid waste.
Plans, Programs, or Policies (PPPs)

WILDFIRES. If located in or near state
responsibility areas or lands classified as very
high fire hazard severity zones, would the
project:
a) Substantially impair an adopted emergency
response plan or emergency evacuation plan?
b) Due to slope, prevailing winds, and other
factors, exacerbate wildfire risks, and thereby
expose project occupants to, pollutant
concentrations from a wildfire or the uncontrolled
spread of a wildfire?
c) Require the installation or maintenance of
associated infrastructure (such as roads, fuel
breaks, emergency water sources, power lines or
other utilities) that may exacerbate fire risk or
that may result in temporary or ongoing impacts
to the environment?
d) Expose people or structures to significant risks,
including downslope or downstream flooding or
landslides, as a result of runoff, post-fire slope
instability, or drainage changes?
a) Substantially impair an adopted emergency response plan or emergency evacuation plan? Less Than Significant Impact. According to the CAL FIRE Hazard Severity Zone map, the Project site is within a Local Responsibility Area (LRA) and within an area identified as a VFHSZ (CALFIRE 2023). Additionally, as stated in Section 5.9 of this IS/MND, the proposed Project would not physically interfere with an adopted emergency response plan or emergency evacuation plan. The proposed Project does not include any characteristics (e.g., permanent road closures or long-term blocking of road access) that would substantially impair or otherwise conflict with an emergency response plan or emergency evacuation plan. Further, the proposed Project would not obstruct or alter any transportation routes that could be used as evacuation routes during emergency events.
During construction, construction worker parking and equipment staging would occur on the area in front of the existing City-owned single-family residence, approximately 300 feet southwest of the reservoir area.
Thus, construction of the Project would not impair access to North Glendora Avenue.
During operation of the proposed Project, the reservoirs would be accessed on a weekly basis to collect residuals and maintain the site. Maintenance operators would access the site via the existing access road off North Glendora Avenue.
Additionally, access to and from the Project site for emergency vehicles would be reviewed and approved by the Los Angeles County Fire Department and the City as part of the Project approval process to ensure the proposed Project is compliant with all applicable codes and ordinances for emergency vehicle access.
Further, the nearest fire station to the Project site is Los Angeles County Fire Dept. Station 151, located Mitigated Negative Declaration
City of Glendora North Glendora Reservoir Replacement Project 150
approximately 1.25 miles south of the site. Since the Project is required to comply with all applicable City codes, as verified by the City, any potential impacts related to an emergency response or evacuation (if any) would be less than significant.
b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollution concentrations from a wildfire or the uncontrolled spread of a wildfire?
Less than Significant Impact. As stated previously, the Project site is located within a VHFHSZ. However, the proposed Project would not change existing land uses on the Project site. As such, the Project would not introduce habitable structures or change activities at the Project site such that new hazards associated with wildfire would be introduced.
During construction of the Project, heavy duty equipment and machinery would be used to demolish the existing reservoir, install replacement reservoirs, and implement utility improvements along the access road from North Glendora Avenue. In accordance with PRC Section 4442, the use of spark arrestors is mandated on earth-moving and portable construction equipment with internal combustion engines operating on any forest-covered, brush-covered, or grass-covered land, to prevent the emission of flammable debris from exhaust. In addition, PRC Section 4431 specifies standards for conducting construction activities on days when a burning permit is required, and PRC Section 4428 requires construction contractors to maintain fire suppression equipment during the highest fire danger period (April through November) when operating on or near any forest-covered, brush-covered, or grass-covered land, such as the adjacent open space. Strict adherence to PRC standards during construction (incorporated into the Project as PPP W-1, PPP W-2, and PPP W-3, respectively) would further reduce the risk of wildfire. Therefore, Project construction would not exacerbate wildfire risk. Impacts would be less than significant. c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines, or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? No Impact. The Project does not require the installation or maintenance of associated infrastructure (including roads, fuel breaks, emergency water sources, power lines, or other utilities) that would exacerbate fire risk or that would result in impacts to the environment. During construction of reservoir NGR-A, the existing reservoir B would remain in operation, thus sufficient water would be available for firefighting purposes during Project construction. While the Project includes widening of the access road off North Glendora Avenue within the Project site, the Project does not include any changes to public or private roadways that would exacerbate fire risk or that would result in impacts to the environment. Further, although utility improvements, including construction of inlet/outlet pipelines, overflow and bottom drain pipelines proposed as part of the Project, these utility improvements would be underground and would not exacerbate fire risk.
Project design and implementation of utility improvements would be reviewed and approved by the City as part of the Project approval process to ensure the proposed Project is compliant with all applicable design standards and regulations. Therefore, the proposed Project would not include infrastructure (such as roads, fuel breaks, emergency water sources, power lines, or other utilities), that would exacerbate fire risk or that would result in impacts to the environment and no impacts would occur. d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? Less Than Significant Impact. According to the FEMA FIRM map #06037C1440F, the Project site is zoned as Flood Zone D, area with flood risk due to levee.
The Project consists of the construction of two new 0.3 MG reservoirs. The proposed reservoirs would be designed and constructed in accordance with the AWWA Standard D100-21 and the most current version Mitigated Negative Declaration
City of Glendora North Glendora Reservoir Replacement Project 151
of the CBC. This would safeguard against major structural failures. Adherence to these standards would reduce potential impacts associated with new construction to a less than significant level.
As established in Section 5.10 of this IS/MND, during Project construction soil would be compacted and drainage patterns would be temporarily altered due to grading, and there would be an increased potential for flooding compared to existing conditions. However, construction BMPs would be identified and implemented as part of the proposed Project. Implementation of construction BMPs would control and direct surface runoff to prevent flooding, and as such, Project construction would not expose people or structures to significant risks related to downslope and downstream flooding. Therefore, impacts would be less than significant.
During operation, the proposed Project would not substantially alter the existing onsite drainage patterns.
Additionally, drainage runoff from the Project site would be adequately handled by the proposed Project’s drainage system. Onsite drainage would be collected via grated catch basins located adjacent to each reservoir before flowing into a 12-inch diameter PVC drain pipe, which would outlet to the existing grouted riprap outlet on the east side of the site. Therefore, impacts would be less than significant.
As established in Section 5.7 of this IS/MND, the risk of slope failure represents a limited level of concern on the Project site. Further, projects in the City of Glendora are required to comply with the CBC, which would include the incorporation of: 1) seismic safety features to minimize the potential for significant effects as a result of earthquakes; 2) proper building footings and foundations; and 3) construction of the building structures so that it would withstand the effects of strong ground shaking. These features would reduce potential impacts related to landslides to a less than significant level. Therefore, with implementation of the CBC, the Project would not expose people or structures to significant risks, including downslope or downstream landslides, and impacts (if any) would be less than significant.
Plans, Programs, or Policies (PPPs)
PPP W-1: PRC Section 4442. The Project is required to comply with the provisions of California Public Resources Code (PRC) Section 4442 which states no person shall use, operate, or allow to be used or operated, any internal combustion engine which uses hydrocarbon fuels on any forest-covered land, brushcovered land, or grass-covered land unless the engine is equipped with a spark arrester.
PPP W-2: PRC Section 4431: The Project is required to comply with the provisions of California Public Resources Code (PRC) Section 4431 which specifies that during any time of the year when burning permits are required, no person shall use or operate any portable saw, auger, drill, tamper, or other portable tool powered by a gasoline-fueled internal combustion engine on or near any forest-covered land, brush-covered land, or grass-covered land, within 25 feet of any flammable material, without providing and maintaining at the immediate locations of use or operation of the saw or tool, for firefighting purposes one serviceable round point shovel, with an overall length of not less than 46 inches, or one serviceable fire extinguisher.
PPP W-3: PRC Section 4428: The Project is required to comply with the provisions of California Public Resources Code (PRC) Section 4428 which requires construction contractors to maintain fire suppression equipment during the highest fire danger period (April 1 through December 1) when operating on or near any forest-covered, brush-covered, or grass-covered land, such as the adjacent open space.

Less Than Significant Impact with Mitigation Incorporated. Based on the discussion in Section 5.4, Biological Resources, with implementation of mitigation measures, the proposed Project would not result in significant impacts related to habitat, wildlife species, and/or plant and animal communities. No special-status plant species were identified onsite, however, one special-status wildlife species was identified in the Study Area:
Southern California rufous-crowned sparrow. Additionally coastal California gnatcatcher, Pallid bat, western mastiff bat and Big free-tailed bat were identified as having the potential to occur onsite. Further, the Project contains two habitat types deemed sensitive by the City of Glendora: Coastal Sage Scrub and Woodlands.
As a result, Mitigation Measure BIO-1 is incorporated to require delineation of Project impact areas to prevent the unauthorized impact of habitat outside of Project impact areas. Mitigation Measure BIO-2 is incorporated to require that vegetation clearing, and initial grading is conducted outside of the nesting bird breeding season (February 15 – September 15) or to conduct pre-construction nesting bird surveys.
Mitigation Measure BIO-3 is incorporated to require preparation of a Habitat Restoration Plan that will detail requirements for mitigating impacts to Open Coast Live Oak Woodland and Diegan Coastal Sage scrub, deemed sensitive within the Glendora Community Plan. Implementation of Mitigation Measures BIO1, BIO-2 and BIO-3 would reduce potential impacts to important examples of California prehistory to a less than significant level.
As described in Section 5.5, Cultural Resources, the Project site does not contain any buildings or structures that meet any of the California Register of Historical Resources (California Register) criteria or qualify as “historical resources” as defined by CEQA. Therefore, the proposed Project would not cause a substantial Mitigated Negative Declaration
City of Glendora North Glendora Reservoir Replacement Project 153
adverse change in the significance of a historical resource. The records search conducted as part of the Cultural Resources Assessment did not identify any historic, archaeological, or cultural resources on the Project site. However, it did reveal previously identified resources within one-half mile of the Project site. As a result of proximity to historic resources and a positive SLF result, there is a potential for archaeological resources to exist on site. However, Mitigation Measure CUL-1 has been included to require archaeological evaluation in the event a resource is inadvertently discovered. Additionally, Mitigation Measures TCR-1, TCR-2, TCR-3 and TCR-4 have been included to require a qualified archaeologist to coordinate with YSMN and Kizh Nation in the event of a pre-contact and/or historic-era cultural resource discovery. Implementation of Mitigation Measures TCR-1, TCR-2, TCR-3 and TCR-4 would reduce potential impacts to important examples of California prehistory to a less than significant level. b) Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)?
Less Than Significant with Mitigation Incorporated. As presented in this document, potential Project-related impacts are either less than significant or would be less than significant with mitigation incorporated. Given that the potential Project-related impacts would be mitigated to a less than significant level, implementation of the proposed Project would not result in impacts that are cumulatively considerable when evaluated with the impacts of other current projects, or the effects of probable future projects. Therefore, the proposed Project’s contribution to any significant cumulative impacts would be less than cumulatively considerable. As discussed in Sections 5.1 through 5.20 of this document, mitigation would be required and incorporated as necessary. Therefore, impacts would be less than significant with mitigation incorporated. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?
Less Than Significant with Mitigation Incorporated. Based on the Project Description and the preceding responses in Sections 5.1 through 5.20 of this document, implementation of the proposed Project would not cause substantial adverse effects to human beings because all potentially significant impacts of the proposed Project would be mitigated to a less than significant level. Therefore, since all potentially significant impacts of the proposed Project are expected to be mitigated to a less than significant level, implementation of the proposed Project would not cause substantial adverse effects on human beings.
