MEMORANDUM
To: City of Sunnyvale
Attn: Deepti Jain
From: Brad Stoneman
Kimley-Horn and Associates, Inc.
Date: April 2025
Subject: Traffic Memorandum Sunnyvale SMaRT Station 2022 Addendum Summary
This memorandum has been prepared to document the potential changes in traffic and circulation that could occur from implementation of the proposed updates to the Sunnyvale SMaRT Station (updated SMaRT Station project). This memorandum provides background information related to traffic impacts that were discussed in the original 1990 EIR for the SMaRT Station. The SMaRT Station is located at 301 Carl, Drive in the City of Sunnyvale (City) and is located within the boundaries of and is a part of the operations of the Sunnyvale Landfill. While this memorandum discusses the past findings in relation to traffic and project effects on level of service, it also discusses the newer requirements of Assembly Bill (AB 743). AB 743 required a discussion of traffic impacts in terms of vehicle miles travelled (VMT).
The EIR for the original SMaRT Station project in 1990 was prepared in accordance with the California Environmental Quality Act (CEQA) Guidelines in effect at that time. Two subsequent EIR Addendums, one in 1992 and one in 2016 were prepared to account for minor changes to the operations and service area of the SMaRT Station. Additional minor changes have been proposed for the SMaRT Station for which a new Addendum is being prepared.
Using the previous documents as references, this memorandum discusses the potential for the updated SMaRT Station project to result in new or more significant traffic impacts. The memorandum is intended to inform t he analysis for the 2025 Addendum. The updated SMaRT Station project includes the following elements as they relate to transportation.
• Replace the existing and outdated electrically powered equipment with new modern electrically powered equipment.
• Alter the permit with the Bay Area Air Quality Management District (BAAQMD) to account for the updated machinery.
• CalRecycle/Local Enforcement Agency (LEA)
• Update the municipal partnership Memorandum of Understanding (MOU) to remove the City of Palo Alto.
Attachment 3
• Minor excavation to remove existing equipment and level the ground surface within the existing SMaRT Station footprint to enable set of new machinery. • Maintain the existing hours of operation in accordance with the existing permit. • Maintain the permitted traffic volumes (total vehicles entering the site) 760 daily trips on weekdays, 519 daily trips on regular weekends, and 1,390 daily trips on extra dump weekend events.
The updated SMaRT Station project would require approval from BAAQMD because the updates to the SMaRT Station and its operations would require an alteration to the existing BAQMND air quality permit.
The proposed improvements would update outdated electrically powered equipment and machinery used to process waste materials. Minor ground disturbance and leveling of pads is needed to enable installation and setting of the new modern electrically powered equipment. The City of Palo Alto would be removed from the service area but the SMaRT station would continue to provide services to the City of Sunnyvale and City of Mountainview. To account for the changes issuance of a new conditional use permit (CUP) would be needed from the City and an updated solid waste facility permit issued by CalRecycle to account for the updated machinery.
The project does not propose any physical expansion of or modifications to the existing structures. The project would maintain the existing 1,500 gross tons per day processing limit and would not change the service area with the exception of the removal of Palo Alto. The project would not increase the vehicle trips either during construction or as a result of continued operations. The number of employee vehicle trips would temporarily decrease during the approximately 6–12-month construction period. This would be due to reduced intake capacity as machinery is switched out. After construction is complete, there would be a permanent decrease of approximately 21 employees because the new equipment and machinery would be more efficient. This would reduce vehicle trips by approximately 50%.
Project Location and Access
The SMaRT Station is located at 301 Carl Road, in the City of Sunnyvale CA. The proposed project takes primary access via Carl Road from Caribbean Drive for both public and truck access. Caribbean Drive is connected with Lawrence Expressway to the east and Mathilda Avenue to the west. These roadways also provide links to State Route 237 (SR 237).
Carl Road would remain the primary roadway used for direct ingress and egress to the SMaRT Station site. This has not changed since the project was proposed and evaluated in the 1990. Vehicles entering the SMaRT Station would turn north to Carl Road and then proceed east to access the SMaRT Station.
To exit, the vehicles would initially use Carl Road and then turn left to Borregas Avenue to return to Caribbean Drive. Borregas Avenue and Carl Ave are parallel one -ways roadways and are separated by a landscaped median. No changes to this roadway configuration or any other are proposed as part of the updated SMaRT Station project.
Project History
Attachment 3
The original SMaRT station service area consisted of the Cities of Sunnyvale, Mountain View, Palo Alto, and an extended service area. The 1990 EIR considered that the SMaRT Station project w ould result in the generation of approximately 1,832 trips (cars and trucks) per weekday and 1,514 trips on weekends. At that time, the 1990 EIR also contemplated a total intake capacity of 2,200 tons of refuse per day, not the current 1,500 tons per day.
In 1992, an addendum to the SMaRT Station project was prepared. The 1992 was needed to evaluate a reduction in the station size (10 to 9 acres), capacity reduction to 1,500 tons per day, a reconfiguration of the main building, and relocation of the wood waste processing and public buy back areas. The main building was proposed to be reduced from 128,000 square feet (sf) to 111,550 sf. The reduction of the intake capacity also would result in a reduction of vehicle trips by approximately 32% which is discussed in additional detail in the Traffic Impacts section, further below. None of these changes were found to result in additional impacts.
The 2016 Addendum was prepared to account for an increase of the SMaRT Station service area and addition of the City of Milpitas to the service area and associated changes to the Memorandum of Understanding (MOU). Although Milpitas ultimately chose not to be added, the potential increase was considered. The impacts associated with these changes were determined to not result in additional impacts.
CEQA Summary
The potential environmental effects of the SMaRT Station were originally contemplated in 1990. At that time, the environmental review process was completed pursuant to the requirements of the then current California Environmental Quality Act (CEQA) . The Draft Environmental Impact Report (EIR) was circulated for public review and comment. The document was subsequently certified and the Final EIR was published in September of 1990. Two addendums to the project (one in 1992 and one in 2016) were prepared to account for minor changes to the SMaRT Station. The changes did not have the potential to increase the significance of any previously disclosed impact or require additional mitigation that could have an effect on the environment. Since the approval of the previous environmental documents, the CEQA Guidelines have been revised. One of the revisions relates to the analysis of traffic impacts and is based on the requirements of Senate Bill 743 and analysis of vehicle miles travelled (VMT). This bill and its requirements are discussed immediately following.
Senate Bill 743
SB 743 is part of a long- standing policy effort by the California legislature to improve California’s sustainability and reduce greenhouse gas emissions through denser infill development, a reduction in single occupancy vehicles, improved mass transit, etc. At the time of the drafting and eventual passing of SB 743, the California legislature concluded that environmental analysis techniques could encourage development that was inconsistent with the above vision. This contributed to the decision to change the basis of environmental analysis for transportation impacts from Level of Service (LOS) to vehicle miles travelled (VMT).
Attachment 3
VMT is understood to be a good proxy for evaluating air quality and other transportation related impacts that the State is actively trying to address. While the use of VMT to determine significant transportation, impacts has only been considered recently, it is not a new performance metric and has long been used as a basis for transportation system evaluations in the past and has been used to evaluate the performance of Travel Demand Models (TDMs).
While there are several ways to assess VMT, TDMs are often used as the basis for VMT evaluation.
TDMs are used primarily because when compared to other VMT calculation tools, they are sensitive to local and regional conditions and are effective at evaluating land uses that are sensitive to the proximity of other land uses. In addition, TDMs consider other spatial and contextual considerations that other tools do not. TDMs are not without limitations, however, especially when they are used to evaluate a relatively small land use change in a regional context, such as the proposed project.
In accordance with the requirements of SB 743, CEQA guidelines underwent revisions that took effect on July 1, 2020. As part of the revision, transportation impacts were to be evaluated using VMT instead of the previously used and traditional LOS.
VMT is a measure of the actual miles that an individual in their vehicle travel as opposed to LOS which measures the relative flow of vehicles as determined by potential delays along roadways and at intersections, and the time it requires to travel from one point to the next. As part of the CEQA update, Jurisdictions were given until the July 1, 2020, date to implement new thresholds of significance based on the guidance. More specifically, the VMT thresholds are shown in the updated State CEQA § 15064.3 Determining the Significance of Transportation Impacts.
CEQA § 15064.3 (b)(3) provides for qualitative a nalysis of VMT impacts and notes that if existing models or methods are not available to estimate the VMT for the particular project being considered, a lead agency may analyze the project’s vehicle miles traveled qualitatively.
At this time the City has not adopted thresholds or standards of significance that include an analysis of VMT. Therefore, due to the nature of the project (because it would not increase the scale or scope of the SMaRT Station operations and does not propose any new vehicle trips), a qualitative analysis of VMT is used as appropriate.
Summary of Previous Analysis
The 1990 EIR evaluated potential traffic impacts to local roadways and highways consider ing the service capacity and anticipated vehicle trips. The subsequent 1992 Addendum, and the 2016 Addendum considered traffic impacts also using LOS. To reduce impacts, from the project and ensure impacts remained less than significant and LOS was not substantially affected, the 1990 EIR proposed mitigation that was adopted as part of the SMaRT Station project . Mitigation included roadway improvements such as lengthened turn-pockets, signal timing improvements, introduction of stop controls, and signage to clarify circulation patterns and to prevent driver confusion and reduce the potential for delays. The mitigation was implemented and as applicable and if further improvements as part of other unrelated projects were not made, remains in place.
Attachment 3
The 1992 Addendum evaluated a reduction in the SMaRT Station project footprint (from 10 to 9 acres).
These modifications also reduced the operational limits and permitted tonnage from 2,200 tons per day to 1,500 tons per day.
The 2016 Addendum was prepared to account for an increase in the SMaRT Station service area with the addition of the City of Milpitas , although the city ultimately chose not to be included. In both instances, it was determined that no additional impacts would occur.
Traffic Impacts
As discussed above, the 1990 EIR evaluated the SMaRT Station with a permitted in take of 2,200 tons of refuse per day. This evaluation also anticipated the generation of a maximum number of 1,832 weekday vehicle trips, and 1,514 weekend vehicle trips. The 1990 Final EIR concluded that the SMaRT Station would not have significant traffic impacts because the projected number of traffic trips would not have a significant adverse impact on the LOS and operations at the study intersections . The document also concluded that the SMaRT Station project would not significantly increase traffic volumes on roadways within the study area. Nonetheless, mitigation measures were proposed and implement. The mitigation was used to further reduce impacts and impacts were found to be less than significant.
The revisions that were evaluated in the 1992 Addendum proposed to reduce the permitted capacity of the SMaRT Station to 1,500 tons per day . The 1992 Addendum concluded that the proposed 32% reduction in capacity also would result in a 32% reduction in traffic, and 586 fewer trips for a total of 1,246 daily trips . This revision was determined to not result in any new or more significant impacts because it would reduce the number of vehicles on the roadway. No new mitigation measures were proposed or required.
The revised project analyzed in the 2016 Addendu m considered the addition of the City of Milpitas to the service area and although, as noted above, the city chose not to be served, the analysis remains valid and is considered for the purposes of this addendum and the current modifications to the SMaRT Station. The previous evaluation maintained the total capacity of 1,500 tons per day and resulted in the addition of approximately 70 additional truck trips. Table -1 - 2016 and Milpitas Project Trip Generation, shows the number of vehicle trips that were occurring in 2016, as well as the additional trips that were anticipated to be generated from Milpitas.

As shown in Table 1, the addition of the Milpitas service area was projected to add approximately 70 truck trips per day. It should be noted that although the 2016 trip counts did not differentiate between weekday and weekend trips (as was done in the previous evaluation), the total average trips, 968, was 278 fewer daily trips compared to the original 1990 estimate.
The current update to the SMaRT Station project would remove Palo Alto service area waste processed at the facility would only be received from the Cities of Mountain View and Sunnyvale. For the moment, this would result in a reduction of trips and reduce the overall VMT. In addition, according to the SMaRT Station, they are currently receiving approximately 700-800 tons per day and generates approximately 230 weekday trips, 80 weekend trips, in addition to the 600-700 trips that occur per day over four days for the weekend special events.
The SMaRT station also generates trips by providing recycling for approximately 35 tons per day of SSO/organic recycling that requires 10 – 11 trips per day. Approximately 3 trips are generated to transport materials to Sustainable Organic Solutions in Santa Clara – 8 miles, 5 trips are needed to take SSO/organic materials to ZBest in Gilroy – 44 miles away, and 2 trips to the Kirby Landfill – 27 miles away. The SMaRT station will increase these total trips to 14, but this trip increase would be short term and temporary as they would be phased out 95% in approximately 2-2.5 years (2024/2025) when the SSO/organic waste will pumped to the adjacent SWPCP. Although the tonnage of SSO may vary depending on materials received and disposal needs may fluctuate, the range of trips and VMT is not anticipated to fluctuate substantially from those listed above.
Thus, when the Palo Alto service area is removed the trips would be temporarily reduced further. It should be noted, however, the SMaRT Station is not reducing the existing 1,500 tons per day capacity and would maintain the previously accounted for 1,246 trips to ensure future services could be provided.
Conclusion
As discussed, the updated SMaRT Station project does not propose nor would it result in any additional vehicle trips and would not result in a greater VMT. The SMaRT Station project is currently receiving 230 trips per weekday day and 80 weekend trips which is substantially less than the 1,246 trips considered in the 2016 Addendum and the 1,832 considered for the SMaRT Station project evaluated in 1990. This is also 530 less trips than the currently permitted 760 trips.
Attachment 3
As noted, the proposed project would not increase but maintain the 1,500 tons per day limit and would not increase VMT . It also would maintain the 1,246- trip standard under which it was previously evaluated to operates but generates substantially less. In addition, the service area from which additional VMT could be generated would not be expanded. It should be noted that the remaining capacity (approximately 700- 800 tons) could be used in the future to provide continued recycling services which is within the scope of the previous analysis. Thus, services could be provided to other surrounding municipalities, or Milpitas if they wished to receive services without resulting in impacts greater than those previously disclosed. If this occurred, this would not result in additional impacts provided the daily trips do not exceed the volume previously evaluated. Lastly, with the improvements and use or modern equipment, the project would require approximately 21 fewer employees, which would reduce VMT from worker commutes by approximately half . Thus, under the updated SMaRT Project operations - no additional impacts to transportation and traffic would occur.
These conclusions and the information provided above, is consistent with the information available and from previous environmental documentation and planning documents. It is important to note that these conclusions are consistent with the former conclusion in the aforementioned environmental documents and impacts would remain less than significant.
