Executive Summary
This report presents the results of a speed survey analysis completed in the City of Saratoga, California. This
study analyzes the sufficiency of posted speed limits on 44 roadway segments within the Saratoga City
limits. Speed limits for the roadway segments were evaluated and compared to the 85th percentile speed to
make recommendations on whether the speed limit is appropriate and can be radar enforced per California
law. Locations where the 85th percentile speed deviates from the posted speed limit by at least 2.5 miles per
hour were analyzed in more detail.
Overall, the observed 85th percentile speeds have increased slightly as compared to the data from the 2013
Speed Survey. Speeds have increased in one or both directions on 29 of the 44 roadway segments (65%)
and decreased or stayed the same on 14 roadway segments. One new segment (Miller Avenue) was added
to this speed survey and has no recorded 2013 speed data. Based on the observed 85th percentile speeds
alone, speed limits on the following eight roadway segments could be 10 mph higher than the posted limit:
• Chester Avenue from Allendale Avenue to Ten Acres Road (Segment 8)
• Glen Brae Drive from Scotland Drive to Cox Avenue (Segment 17)
• Herriman Avenue from Saratoga-Sunnyvale Avenue to Saratoga Avenue (Segment 18)
• Miller Avenue from Prospect Road to Cox Avenue (Segment 19)
• Pierce Road from Highway 9 to Mount Eden Road (Segment 20)
• Quito Road from Southerly City limit to Bicknell Road (Segment 27)
• Quito Road from Bicknell Road to Pollard Road (Segment 28)
• Scotland Drive from Saratoga Avenue to Cumberland Drive (Segment 42)
The California Vehicle Code (CVC) and Manual on Uniform Traffic Control Devices (MUTCD) allow
consideration of other factors besides the 85th percentile speed when setting posted speed limits. These
factors include existing roadway conditions (e.g., pavement width), on-street residential density, pedestrian
and bicycle safety, and speed-related collision data. Incorporating these factors into the speed survey
evaluation, we recommend the existing speed limits be maintained on all study roadway segments in the
City of Saratoga, except we recommend the City reduce the posted speed limit on the following roadway
segment from 40 mph to 35 mph:
• Saratoga Avenue from Fruitvale Avenue to Dagmar Drive (Segment 35).
The City should continue to monitor speeds on the following eight roadway segments and implement traffic
calming measures as needed to at least maintain and possibly decrease the 85th percentile speeds:

3. Average Daily Traffic Volumes
This section of the report presents the Average Daily Traffic (ADT) volumes for the roadway segments
analyzed for this report. Figure 3 graphically presents the ADT for the 44 study roadway segments analyzed.
All but four of the roadway segments analyzed in this report serve fewer than 25,000 ADT. The following
four roadway segments in the City serve between 25,000 and 40,000 ADT:
• Saratoga Avenue between Fruitvale Avenue and Dagmar Drive (32,300 ADT)
• Saratoga Avenue between Vineyard Lane and Cox Avenue (34,278 ADT)
• Saratoga Avenue between Cox Avenue and Northerly City limit (29,161 ADT)
• Saratoga-Sunnyvale Road between Union Pacific Railroad and Prospect Road (25,550 ADT)
Saratoga Avenue is a major arterial in the City of Saratoga and provides direct access to State Route 85, the
downtown village, and many local schools; therefore, the higher volumes on this roadway are expected.
Similarly, Saratoga-Sunnyvale Road is a major arterial that provides north-south connectivity toward the
western border of the City of Saratoga.

4. Speed Survey Analysis
This section represents the results of a speed survey conducted in Saratoga starting in October 2018
through January 2020. The data from the survey is presented first, followed by the analysis of each segment.
The key measure for analysis is the 85th percentile or critical speed of a roadway segment. The 85th percentile
speed is that speed at which 85 percent of free-flowing vehicles are traveling at or below the posted speed
limit. Special attention is paid to those roadway segments where the 85th percentile speed exceeds the
posted speed limit by 2.5 miles per hour (mph) or greater.
Appendix A contains individual data sheets for all 44 roadway segments analyzed for the 2020 Saratoga
Speed Survey.
Data Collection
Speed surveys were conducted at 44 locations within the City of Saratoga. Some study roadways have
multiple study segments to reflect the changes in posted speeds, traffic volumes, streets width or other
significant factors that vary on a roadway. Automated machine equipment was used to capture existing
average daily traffic (ADT) volumes. Per guidelines from the MUTCD, speeds for high-volume locations were
collected with radar equipment. For those roadway segments that have lower roadway volumes that do not
allow for effective radar observations, automated machine equipment that continually collects traffic data
was used to capture observed travel speeds. The approximate locations of the volume data collection points
are indicated in Figure 1 and correspond with the location number indicator for each roadway segment.
Figure 4 and Figure 5 visually show the 85th percentile speeds for the 44 study roadway segments analyzed.
Based on the speed survey analysis, the posted speed limit at each location was evaluated and
recommendations made on whether the speed limit is appropriate. Specifically, the 85th percentile speed
was used as a baseline comparison to the posted speed limit.
California Vehicle Code
Division 11, Chapter 7, of the California Vehicle Code (CVC) defines the California Speed Laws (also known
as Sections 22348-22413). Relevant sections of the CVC are used to determine speed limits in local
jurisdictions are discussed below.
City of Saratoga
2020 Speed Survey
April 2020

Prima Facie Speed limits
Prima facie speed limits are the innate speed limits on the roadway and shall be applicable unless changed
as authorized in the CVC. Section 22352 of the CVC indicates the following prima facie speed limits.
• 15 mph: at railway crossings, when traversing any intersection with site restrictions, or on
any alley.
• 25 mph: in any business or residence district as defined by Division 1 of the CVC, when
approaching or passing a school building or grounds, or when passing a senior center or other
facility primarily used by senior citizens.
These prima facie speed limits are set by the CVC and the prima facie speed limit of 25 mph can only be
changed based on an Engineering and Traffic Survey.
Engineering and Traffic Survey
In order for the court systems and the public to accept and respect the posting and enforcement, by radar,
of posted speed limits, an Engineering and Traffic Survey must incorporate sound, repeatable methods
conforming to the CVC and engineering principles.
Section 22357(a) stipulates that local authorities may set speed limits greater than 25 mph if an Engineering
and Traffic Survey, such as this, determines that speeds greater than 25 mph would facilitate the orderly
movement of vehicular traffic and would be reasonable and safe upon any street excluding those subject
to a prima facie limit of 25 miles per hour. Based on the Engineering and Traffic Survey, the local authority
may, by ordinance, determine and declare a speed limit of 30, 35, 40, 45, 50, 55, or 60 miles per hour or a
maximum speed limit of 65 miles per hour, whichever is found most appropriate to facilitate the orderly
movement of traffic, and is reasonable and safe.
An Engineering and Traffic Study shall include the consideration of all the following as defined in Section
627 of the CVC:
• Prevailing speeds as determined by the traffic engineering measurements,
• Accident records, and
• Highway, traffic, and roadside conditions not readily apparent to the driver.
In addition to the metrics identified above, local authorities may consider the following:
• Residential density, if any of the following conditions exist on a portion of highway, other than a
business district:
City of Saratoga
2020 Speed Survey
April 2020
13
◦ Upon one side of the highway, within one-quarter mile, the contiguous property fronting
thereon is occupied by 13 or more separate dwelling houses or business structures,
◦ Upon both sides of the highway, collectively, within one-quarter of a mile, the contiguous
property fronting thereon is occupied by 16 or more separate dwelling houses or business
structures, or
◦ The portion of highway is longer than one-quarter of a mile but has the ratio of separate
dwelling houses or business structures to the length of the highway described in the earlier
two points above; and
• Pedestrian and bicycle safety.
The declared speed limits become effective when appropriate speed limit signs are erected on the street.
This does not apply to any 25 mph prima facie limit as it relates to passing a school building, senior center,
or other facility primarily used by senior citizens.
Methodology for Modifying Prima Facie Speed limits
When conducting an Engineering and Traffic Survey to establish speed limits, Section 21400 of the CVC,
and Section 2B.13 of the California Manual of Uniform Traffic Control Devices (MUTCD), requires that local
authorities round the 85th percentile free flow speed to the nearest 5 mph increment to set the appropriate
speed limit, except:
1. The posted speed limit may be reduced by five mph from the nearest five mph increment of the
85th percentile speed, based on guidelines from CVC Section 627 and 22358.5, or
2. In cases where the 85th percentile speed would be rounded up the nearest five miles per hour
increment, local authority may decide to instead round down and set the speed limit to the lower
five miles per hour increment. If the speed limit is set at the lower five mph increment the local
authority shall not reduce the speed limit any further for any reason, including those set forth in
CVC Section 627 and 22358.5.
In addition, the speed limit shall be established at the same level in both directions at a given point on a
roadway for uniformity purposes. Thus, the lower of the two critical speeds may be used to determine the
overall segment speed limit.
In addition to the CVC Section 627 description above, Appendix B contains the text of CVC Section 627
and describes in detail what factors should be taken into consideration when establishing speed limits. A
speed limit can be lowered by five mph to account for these special factors. Establishment of a speed limit
of more than five mph below the 85th percentile speed should only be done after careful consideration.

Segments Summaries
This section of the report analyzes all roadway segments and provides an explanation for necessary speed
adjustments. Where the 85th percentile speed exceeds the posted speed limit by 2.5 mph or greater,
additional information is provided to determine the adequacy of the posted speed limit. Other factors such
as collision records, roadside conditions, and residential density along the roadway, as well as pedestrian
and bicyclist safety are also used in determining the adequacy of the posted speed limits.
Segment 1. Allendale Avenue from Fruitvale Avenue to Portos Court
The posted speed limit on Allendale Avenue from Fruitvale Avenue to Portos Drive is 35 mph. In the
eastbound direction, the 85th percentile speed was measured at 1.0 mph over the posted limit, while in the
westbound direction the 85th percentile speed was measured equal to the current posted speed limit.
The 85th percentile speeds in both eastbound and westbound directions indicate an initial speed limit of 35
mph which is equal to the current posted speed limit. Therefore, we recommend the City maintain the
existing speed limit of 35 mph.
Segment 2. Allendale Avenue from Portos Court to Chester Avenue
The posted speed limit on Allendale Avenue from Portos Court to Chester Avenue is 35 mph. In the
eastbound direction, the 85th percentile speed was measured at 4.0 mph over the posted limit, while in the
westbound direction the 85th percentile speed was measured at 2.0 mph over the posted speed limit.
Since the lower of the two 85th percentile speeds can be used to set the speed limit, the 85th percentile
speeds in the westbound direction indicates an initial speed limit of 35 mph which is equal to the current
posted speed limit. Therefore, we recommend the City maintain the existing speed limit of 35 mph.
Segment 3. Allendale Avenue from Chester Avenue to Quito Road
The posted speed limit on Allendale Avenue from Chester Avenue to Quito Road is 25 mph. The observed
85th percentile speeds were 5.3 mph and 8.8 mph greater than the posted speed limit in the eastbound and
westbound directions respectively, which would initially indicate a posted speed limit of 30 mph.
In the quarter mile distance between Quito Road and Harleigh Drive there are 16 driveways fronting
Allendale Avenue. In accordance with CVC Section 627, the City has the authority to establish the speed
limit at five miles per hour below the limit established by the 85th percentile speed. This section of Allendale
Avenue has no sidewalks and the existing driveways end at the curb of the roadway, and bushes provide
limited visibility to/of vehicles exiting at approximately 13 driveways. There is a dip in the road that is not
apparent to drivers. In the summer of 2013, the City of Saratoga installed a radar feedback sign in the

eastbound direction of this segment of Allendale Avenue as a traffic calming measures to reduce the 85th
percentile speeds. No speed-related collisions have been reported on this section of Allendale for the five-
year period analyzed for this report.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has
the authority to establish the speed limit at five miles per hour below the limit established by the observed
85th percentile speeds. Therefore, due to the residential nature of Allendale Avenue and lack of pedestrian
facilities, we recommend that the City maintain current speed limit of 25 mph.
Segment 4. Arroyo De Arguello from Comer Drive to Via Roncole
The posted speed limit on Arroyo De Arguello from Comer Drive to Via Roncole is 25 mph. The observed
85th percentile speeds were 6.8 mph and 8.1 mph greater than the posted speed limit in the northbound
and southbound directions, respectively, which would initially indicate a posted speed limit of 30 mph.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this
roadway segment. Additionally, Arroyo De Arguello has discontinuous sidewalks on the west side of the
street and no bicycle facilities on either side of the roadway. In accordance with CVC Section 627, the City
has the authority to establish the speed limit at five miles per hour below the limit established by the 85th
percentile speed. No speed-related collisions have been reported on this section of Arroyo De Arguello for
the five-year period analyzed for this report.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has
the authority to establish the speed limit at five miles per hour below the limit established by the observed
85th percentile speeds. Therefore, due to the residential nature of Arroyo De Arguello and lack of
pedestrian/bicycle facilities, we recommend that the City maintain current speed limit of 25 mph.
Segment 5. Beaumont Avenue from Herriman Avenue to Glasgow Drive
The posted speed limit on Beaumont Avenue from Herriman Avenue to Glasgow Drive is 25 mph. The 85th
percentile speeds were observed to be 4.3 mph and 4.6 mph in excess of the posted speed limit in the
northbound and southbound directions, respectively, which would initially indicate a posted speed limit of
30 mph.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per
hour increment of the 85th percentile speed would require rounding up, then the speed limit may be
rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no further
reduction is used. The 85th percentile speeds in both northbound and southbound directions were rounded
up to indicate an initial speed limit of 30 mph, which can be rounded down to 25 mph. Therefore, we
recommend the City maintain the existing speed limit of 25 mph.

The posted speed limit of Bucknall Road from Saratoga Avenue to Quito Road is 25 mph. In the eastbound
direction the 85th percentile speed was measured at 6.0 mph over the posted limit, while in the westbound
direction the 85th percentile speed was measured at 4.0 mph over the posted speed limit, which would
initially indicate a posted speed limit of 30 mph.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per
hour increment of the 85th percentile speed would require rounding up, then the speed limit may be
rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no further
reduction is used. The 85th percentile speeds in both northbound and southbound directions were rounded
up to indicate an initial speed limit of 30 mph, which can be rounded down to 25 mph. Therefore, we
recommend the City maintain the existing speed limit of 25 mph.

85th percentile speeds were observed to be 4.0 mph and 5.0 mph in excess of the posted speed limit in the
City of Saratoga
2020 Speed Survey

northbound and southbound directions, respectively, which would initially indicate a posted speed limit of
45 mph.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per
hour increment of the 85th percentile speed would require rounding up, then the speed limit may be
rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no further
reduction is used. The 85th percentile speeds in both northbound and southbound directions were rounded
up to indicate an initial speed limit of 45 mph, which can be rounded down to 40 mph. Therefore, we
recommend the City maintain the existing speed limit of 40 mph.
Segment 40. Saratoga-Sunnyvale Road from Blauer Drive to Union Pacific Railroad
The posted speed limit on Saratoga-Sunnyvale Road from Blauer Drive to Union Pacific Railroad is 40 mph.
In the northbound direction, the 85th percentile speed was measured at 3.0 mph over the posted limit, while
in the southbound direction the 85th percentile speed was measured at 1.0 mph over the posted speed limit.
Since the lower of the two 85th percentile speeds can be used to set the speed limit, the 85th percentile
speeds in the southbound direction indicate an initial speed of 40 mph which is equal to the current posted
speed limit. Therefore, we recommend the City maintain the existing speed limit of 40 mph.
Segment 41. Saratoga-Sunnyvale Road from Union Pacific Railroad to Prospect Road
The posted speed limit on Saratoga-Sunnyvale Road from Union Pacific Railroad to Prospect Road is 40
mph. In the northbound direction, the 85th percentile speed was measured equal to the current posted
speed limit, while in the southbound direction the 85th percentile speed was measured 1.0 mph over the
posted speed limit.
The 85th percentile speeds in both northbound and southbound directions indicate an initial speed limit of
40 mph which is equal to the current posted speed limit. Therefore, we recommend the City maintain
the existing speed limit of 40 mph.
Segment 42. Scotland Drive from Saratoga Avenue to Cumberland Drive
The posted speed limit on Scotland Drive from Saratoga Avenue to Cumberland Drive is 25 mph. The
observed 85th percentile speeds were 8.3 mph and 9.1 mph greater than the posted speed limit in the
northbound and southbound directions, respectively, which would initially indicate a posted speed limit of
35 mph.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this
roadway segment. Scotland Drive has no sidewalks or bicycle facilities on either side of the roadway. No

speed-related collisions have been reported on this section of Scotland Drive for the five-year period
analyzed for this report.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per
hour increment of the 85th percentile speed would require a rounding up, then the speed limit may be
rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no further
reduction is used. The 85th percentile speeds in both northbound and southbound directions were rounded
up to indicate an initial speed limit of 35 mph, which can be rounded down to 30 mph. However, due to
the segment properties explained above such as the residential nature of the segment and the lack
of adequate bicycle and pedestrian facilities, we recommend that the City maintain the current speed
limit of 25 mph. The City should monitor this segment of Scotland Drive for possible traffic calming
measures to reduce the 85th percentile speeds.
Segment 43. Seagull Way from Saratoga-Sunnyvale Road to Cox Avenue
The posted speed limit of Seagull Way from Saratoga-Sunnyvale Road to Cox Avenue is 25 mph. In the
eastbound direction the 85th percentile speed was measured at 7.0 mph over the posted limit, while in the
westbound direction the 85th percentile speed was measured at 6.4 mph over the posted speed limit. The
85th percentile speeds would initially indicate raising the speed limit to 30 mph.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this
roadway segment. Seagull Way has sidewalks on the west side of the street, with inconsistent sidewalks on
the east side of the street. There are no bicycle facilities on either side of the roadway. Additionally based
on the CVC (CVC 40802 (b)) and the existing roadway geometries, this segment of Seagull Way qualifies as
a local street with a prima facie speed of 25 mph. No speed-related collisions have been reported for this
segment of Seagull Way for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has
the authority to establish the speed limit at five miles per hour below the limit established by the observed
85th percentile speeds. Therefore, due to the residential nature of Seagull Way and lack of adequate
pedestrian/ bicycle facilities, we recommend that the City maintain current speed limit of 25 mph.
Segment 44. Sobey Road from Northerly Quito Road to Southerly Quito Road
The posted speed limit of Sobey Road from Northerly Quito Road to Southerly Quito Road is 30 mph. In
the northbound direction the 85th percentile speed was measured at 7.7 mph over the posted limit, while
in the southbound direction the 85th percentile speed was measured at 6.6 mph over the posted speed limit.
The 85th percentile speeds would initially indicate raising the speed limit to 35 mph.

Sobey Road is a winding local road that fronts private residents. The roadway width of the roadway varies
between 20 and 40 feet. In terms of pedestrian and bicycle safety, Sobey Road does not provide any bike
lanes or any continuous sidewalks. No speed-related collisions have been reported for this segment of
Sobey Road for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has
the authority to establish the speed limit at five miles per hour below the limit established by the observed
85th percentile speeds. Therefore, due to the lack of adequate pedestrian/ bicycle facilities, we recommend
that the City maintain current speed limit of 30 mph.

5. Comparison of 2020 Speeds to
2013 Survey
This section of the report compares the observed 85th percentile speeds collected for this report, to those
observed in the 2013 speed survey. Specifically, this section presents a comparison of the trends in observed
speeds in the City. Table 2 compares the 85th percentile speeds for the 2013 and 2020 speed data and
Figure 7 shows the difference in the observed 85th percentile speeds between year 2013 and year 2020
data (2020 minus 2013).
As shown in Table 2, more than half of the 85th percentile speeds have increased as compared to data from
2013. On the following 29 roadway segments the 85th percentile speeds increased in one or both directions
as compared to data collected in 2013.

The greatest increase in the 85th percentile speed between 2013 and 2020 occurred on Prospect Road from
Lawrence Expressway to Easterly City limit (Segment 26) with a four miles per hour increase in the eastbound
direction. The speeds on Prospect Road from Lawrence Expressway to Easterly City limit however, only
increased by three miles per hour in the westbound direction. The largest decrease in speed occurred on
Beaumont Avenue from Herriman Ave to Glasgow Dr (Segment 5), which decreased by 4.0 and 6.0 mph in
eastbound and westbound directions, respectively.
For those segments where the 85th percentile speeds increase compared to 2013 data, the average increase
was approximately by 1.35 mph. Conversely, the 85th percentile speeds decreased on average by about 1.67
mph for those segments where the speeds decreased as compared to 2013.

California Vehicle Code (CVC) Section 40802 requires speed limits be justified by an Engineering and Traffic Survey conducted in accordance with
methods determined by the Department of Transportation. Speed limits are legally required to be established at the nearest five (5) mph increment to the
85th percentile speed. The 85th percentile speed is defined as that speed at or below which 85 percent of the traffic is moving. This means that a
segment with an 85th percentile speed of 27.4 miles per hour can be posted for 25 mph, while a segment with a critical speed of 27.5 mph must be posted
at 30 mph. However, Section 627 of the California Vehicle Code (CVC) stipulates that other factors besides the 85th percentile speed such as accident
records, roadside conditions, residential density along the roadway, as well as pedestrian and bicyclist safety can be considered when determining speed
limits.

Summary and Justification:
In the eastbound direction, the 85th percentile speed was measured at 1.0 mph over the posted limit, while in the westbound direction the 85th percentile
speed was measured equal to the current posted speed limit.
The 85th percentile speeds in both eastbound and westbound directions indicate an initial speed limit of 35 mph which is equal to the current posted
speed limit. Therefore, we recommend the City maintain the existing speed limit of 35 mph.
Notes: This roadway segment is close to one or multiple schools. The speed limit is twenty-five miles per hour when approaching or passing a school
building or the grounds while children are going to or leaving the school either during school hours or during the noon recess period.

NumberAccident History:
The observed 85th percentile speeds were 5.3 mph and 8.8 mph greater than the posted speed limit in the eastbound and westbound directions respectively, which would initially require a posted speed
limit of 30 mph.
In the quarter mile distance between Quito Road and Harleigh Drive there are 16 driveways fronting Allendale Avenue. In accordance with CVC Section 627, the City has the authority to establish the
speed limit at five miles per hour below the limit established by the 85th percentile speed. This section of Allendale Avenue has no sidewalks and the existing driveways end at the curb of the roadway,
and bushes provide limited visibility to/of vehicles exiting at approximately 13 driveways. There is a dip in the road that is not apparent to drivers. In the summer of 2013, the City of Saratoga installed a
radar feedback sign in the eastbound direction of this segment of Allendale Avenue as a traffic calming measures to reduce the 85th percentile speeds. No speed-related collisions have been reported on
this section of Allendale for the five-year period analyzed for this report.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five miles per hour below the limit established by the
observed 85th percentile speeds. Therefore, due to the residential nature of Allendale Avenue and lack of pedestrian facilities, we recommend that the City maintain current speed limit of 25 mph.

California Vehicle Code (CVC) Section 40802 requires speed limits be justified by an Engineering and Traffic Survey conducted in accordance with
methods determined by the Department of Transportation. Speed limits are legally required to be established at the nearest five (5) mph increment to the
85th percentile speed. The 85th percentile speed is defined as that speed at or below which 85 percent of the traffic is moving. This means that a
segment with an 85th percentile speed of 27.4 miles per hour can be posted for 25 mph, while a segment with a critical speed of 27.5 mph must be posted
at 30 mph. However, Section 627 of the California Vehicle Code (CVC) stipulates that other factors besides the 85th percentile speed such as accident
records, roadside conditions, residential density along the roadway, as well as pedestrian and bicyclist safety can be considered when determining speed
limits.

The observed 85th percentile speeds were 8.3 mph and 7.8 mph greater than the posted speed limit in the northbound and southbound directions respectively which would initially require
a posted speed limit of 35 mph.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway segment. Additionally, Arroyo De Arguello has discontinuous sidewalks
on the west side of the street and no bicycle facilities on either side of the roadway. In accordance with CVC Section 627, the City has the authority to establish the speed limit at five miles
per hour below the limit established by the 85th percentile speed. No speed-related collisions have been reported on this section of Arroyo De Arguello for the five-year period analyzed for
this report.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per hour increment of the 85th percentile speed would require a rounding up, then
the speed limit may be rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no further reduction is used. The 85th percentile speeds in both
northbound and southbound directions were rounded up to indicate an initial speed limit of 35 mph, which can be rounded down to 30 mph. However, due to the segment properties
explained above such as residential nature of the segment and the lack of adequate bicycle and pedestrian facilities along the segment, we recommend that the City maintain the current
speed limit of 25 mph.

The 85th percentile speeds were observed to be 4.3 mph and 4.6 mph in excess of the posted speed limit in the northbound and southbound directions
respectively.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per hour increment of the 85th percentile speed

school on the other side of the street. A raised, mid-block crosswalk is located approximately halfway between Saratoga Avenue and Paseo Presada to guide
pedestrians, especially elderly residents. In addition, El Quito Park is located on Paseo Presada north of Cox Avenue and is also a pedestrian attractor. No speed-
related collisions have been reported for this segment of Cox Avenue for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five miles per hour
below the limit established by the observed 85th percentile speeds. Therefore, to provide improved environment for pedestrians and bicyclists, we recommend that the
City maintain current speed limit of 25 mph .

California Vehicle Code (CVC) Section 40802 requires speed limits be justified by an Engineering and Traffic Survey conducted in accordance with
methods determined by the Department of Transportation. Speed limits are legally required to be established at the nearest five (5) mph increment to the
85th percentile speed. The 85th percentile speed is defined as that speed at or below which 85 percent of the traffic is moving. This means that a
segment with an 85th percentile speed of 27.4 miles per hour can be posted for 25 mph, while a segment with a critical speed of 27.5 mph must be posted
at 30 mph. However, Section 627 of the California Vehicle Code (CVC) stipulates that other factors besides the 85th percentile speed such as accident
records, roadside conditions, residential density along the roadway, as well as pedestrian and bicyclist safety can be considered when determining speed
limits.

In the northbound direction the 85th percentile speed was measured at 8.3 mph over the posted limit, while in the southbound direction the 85th percentile
speed was measured at 5.9 mph over the posted speed limit. The 85th percentile speeds would initially indicate raising the speed limit to 30 mph.
Farwell Avenue is a narrow, 0.6-mile long local road that bends at ninety degrees at its halfway point. Additionally, Farwell Avenue does not include
sidewalks or bicycle lanes, which forces pedestrians and cyclists to use the roadway with vehicles. No speed-related collisions have been reported for this
segment of Farwell Avenue for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five
miles per hour below the limit established by the observed 85th percentile speeds. Therefore, due to the roadway conditions of Farwell Avenue and lack of
pedestrian/ bicycle facilities, we recommend that the City maintain current speed limit of 25 mph.

The 85th percentile speeds were observed to be 3.0 mph and 4.0 mph in excess of the posted speed limit in the northbound and southbound directions
respectively.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per hour increment of the 85th percentile speed
would require rounding up, then the speed limit may be rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no
further reduction is used. The 85th percentile speeds in both northbound and southbound directions were rounded up to indicate an initial speed limit of 40
mph, which can be rounded down to 35 mph. Therefore, we recommend the City maintain the existing speed limit of 35 mph.

California Vehicle Code (CVC) Section 40802 requires speed limits be justified by an Engineering and Traffic Survey conducted in accordance with
methods determined by the Department of Transportation. Speed limits are legally required to be established at the nearest five (5) mph increment to the
85th percentile speed. The 85th percentile speed is defined as that speed at or below which 85 percent of the traffic is moving. This means that a
segment with an 85th percentile speed of 27.4 miles per hour can be posted for 25 mph, while a segment with a critical speed of 27.5 mph must be posted
at 30 mph. However, Section 627 of the California Vehicle Code (CVC) stipulates that other factors besides the 85th percentile speed such as accident

In the northbound direction the 85th percentile speed was measured at 12.2 mph over the posted speed limit, while in the southbound direction the 85th percentile
speed was measured at 10.6 mph over the posted speed limit. The 85th percentile speeds would initially indicate raising the speed limit to 35 mph.
Pierce Road is a winding roadway with limited visibility at curves that has narrow shoulders, and no sidewalks are provided. Bicyclists and pedestrians frequently use
Pierce Road for recreational activities. Additionally, six speed-related collisions have been reported for this segment of Pierce Road for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five miles per hour
below the limit established by the observed 85th percentile speed, which would be 30 mph. However due to the roadway conditions, limited sight distance at numerous

In the northbound direction the 85th percentile speed was measured at 7.3 mph over the posted limit, while in the southbound direction the 85th percentile
speed was measured at 6.8 mph over the posted speed limit. The 85th percentile speeds would initially indicate raising the speed limit to 30 mph.
This section of Pierce Road is similar to the Segment 32: Pierce Road from Highway 9 to Mount Eden Road described above. In addition, two speed-
related collisions have been reported for this segment of Pierce Road for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five
miles per hour below the limit established by the observed 85th percentile speeds. Therefore, we recommend that the City maintain current speed limit of
25 mph.

California Vehicle Code (CVC) Section 40802 requires speed limits be justified by an Engineering and Traffic Survey conducted in accordance with
methods determined by the Department of Transportation. Speed limits are legally required to be established at the nearest five (5) mph increment to the
85th percentile speed. The 85th percentile speed is defined as that speed at or below which 85 percent of the traffic is moving. This means that a
segment with an 85th percentile speed of 27.4 miles per hour can be posted for 25 mph, while a segment with a critical speed of 27.5 mph must be posted
at 30 mph. However, Section 627 of the California Vehicle Code (CVC) stipulates that other factors besides the 85th percentile speed such as accident
records, roadside conditions, residential density along the roadway, as well as pedestrian and bicyclist safety can be considered when determining speed
limits.

In the eastbound direction, the 85th percentile speed was measured at 3.0 mph over the posted speed limit, while in the westbound direction the 85th
percentile speed was at 2.0 mph over the posted speed.
Since the lower of the two 85th percentile speeds can be used to set the speed limit, the 85th percentile speeds in the westbound direction indicate an
initial speed limit of 40 mph which is equal to the current posted speed limit. Therefore, we recommend the City maintain the existing speed limit of 40
mph.
Notes: This roadway segment is close to one or multiple schools. The speed limit is twenty-five miles per hour when approaching or passing a school

The observed 85th percentile speeds were 10.0 mph and 8.0 mph greater than the posted speed limit in the northbound and southbound directions, respectively, which would initially
require a posted speed limit of 40 mph.
Quito Road is a two-lane collector street that connects Saratoga-Los Gatos Road with Saratoga Road. No continuous sidewalks or pathways are provided on the entire segment of Quito
Road. Additionally, this segment of Quito Road is fairly straight and narrow, and only includes one ten- to twelve-foot travel lane in each direction, for a total pavement width of 24-feet. No
speed-related collisions have been reported on this section of Quito Road for the five-year period analyzed for this report.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per hour increment of the 85th percentile speed would require a rounding up, then
the speed limit may be rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no further reduction is used. The 85th percentile speeds in both

In both northbound and southbound directions the 85th percentile speed was measured at 12.0 mph over the posted speed limit. The 85th percentile
speeds would initially indicate raising the speed limit to 35 mph.
This segment of Quito Road is very narrow and does not provide additional pedestrian and bicycle facilities. This 25-mph section of road is located in
between two 30-mph sections of roadway which may be confusing to drivers along Quito Road. Three speed-related collisions have been reported for this
segment of Quito Road for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five
miles per hour below the limit established by the observed 85th percentile speed, which would be 30 mph. However due to the segment properties
identified above such as the roadway conditions, limited sight distance at numerous locations, and lack of pedestrian and bicycle facilities, we recommend
that the City maintain current speed limit of 25 mph.

measured at 6.0 mph over the posted speed limit. The 85th percentile speeds would initially indicate raising the speed limit to 35 mph.
Marshall Lane Elementary School is located just west of Quito Road, and therefore Quito Road serves as an access route for vehicles, bicycles, and pedestrians
traveling to the school. There are separated pedestrian paths along both sides of this section of Quito Road to accommodate the large amount of pedestrian activity.
Quito Road experiences a large amount of recreational bicycle traffic that travels along the narrow roadway. Additionally, three speed-related collisions have been
reported for this segment of Quito Road for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five miles per hour
below the limit established by the observed 85th percentile speeds. Therefore, we recommend that the City maintain current speed limit of 30 mph.

The 85th percentile speeds were observed to be 5.0 mph in excess of the posted speed limit in both directions.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per hour increment of the 85th percentile speed
would require rounding up, then the speed limit may be rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no
further reduction is used. The 85th percentile speeds in both directions were rounded up to indicate an initial speed limit of 40 mph, which can be rounded
down to 35 mph. Therefore, we recommend the City maintain the existing speed limit of 35 mph.

California Vehicle Code (CVC) Section 40802 requires speed limits be justified by an Engineering and Traffic Survey conducted in accordance with
methods determined by the Department of Transportation. Speed limits are legally required to be established at the nearest five (5) mph increment to the
85th percentile speed. The 85th percentile speed is defined as that speed at or below which 85 percent of the traffic is moving. This means that a
segment with an 85th percentile speed of 27.4 miles per hour can be posted for 25 mph, while a segment with a critical speed of 27.5 mph must be posted
at 30 mph. However, Section 627 of the California Vehicle Code (CVC) stipulates that other factors besides the 85th percentile speed such as accident
records, roadside conditions, residential density along the roadway, as well as pedestrian and bicyclist safety can be considered when determining speed
limits.

Saratoga Avenue provides direct access to downtown Saratoga, which is located just south of Saratoga-Sunnyvale Avenue. Pedestrian and bicycle access is limited to
a path on the east side of Saratoga Avenue. Residents from the west side of Saratoga Avenue need to cross Saratoga Avenue mid-block to access the path, which also
provides connection to City services north on Saratoga Avenue, such as the Library and Community Center. No speed-related collisions have been reported for this
segment of Saratoga Avenue for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five miles per hour
below the limit established by the observed 85th percentile speeds. Therefore, due to the proximity of Saratoga Avenue to pedestrian generated land uses and lack of
adequate pedestrian/ bicycle facilities, we recommend that the City maintain current speed limit of 35 mph.

In both northbound and southbound directions the 85th percentile speed was measured at 6.0 mph over the posted speed limit. The 85th percentile
speeds would initially indicate raising the speed limit to 40 mph.
In the quarter mile distance between Westerly Shadow Oaks Way and before arriving at Baroni Court, there are over 16 driveways fronting Saratoga
Avenue. In addition, the existing driveways end at the curb of roadway where bushes provide limited visibility to/of vehicles exiting the driveways. School
crossings are provided across Saratoga Avenue at Herriman Way and full sidewalks are not provided continuously on both sides of the roadway. Three
speed-related collisions have been reported for this segment of Saratoga Avenue for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five
miles per hour below the limit established by the observed 85th percentile speeds. Therefore, due to the residential nature of Saratoga Avenue and lack of

In the northbound direction, the 85th percentile speed was measured at 1.0 mph over the posted limit, while in the southbound direction the 85th percentile speed was
measured at 2.0 mph over the posted speed limit. The 85th percentile speeds in both directions indicate an initial speed limit of 40 mph.
Saratoga Avenue is split between the segments north and south of the State Route 85 interchange. Currently, the speed limits along Saratoga Avenue start at 35 mph
at the south end of the roadway and increase to 40 mph at Fruitvale Avenue and continue through the interchange to the northern end of Saratoga Avenue. The City
has expressed interest in maintaining a consistent speed limit on Saratoga Avenue south of the SR 85 interchange which would indicate a speed limit of 35 mph. In
addition, fifteen speed related collisions have been reported for this segment of Saratoga Avenue for the five-year period analyzed.
In accordance with CVC Section 627, the City has the authority to establish the speed limit at five miles per hour below the limit established by the observed 85th

The 85th percentile speeds were observed to be 3.0 mph and 4.0 mph in excess of the posted speed limit in the northbound and southbound directions
respectively.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per hour increment of the 85th percentile speed
would require rounding up, then the speed limit may be rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no
further reduction is used. The 85th percentile speeds in both northbound and southbound directions were rounded up to indicate an initial speed limit of 45
mph, which can be rounded down to 40 mph. Therefore, we recommend the City maintain the existing speed limit of 40 mph.
Notes: This roadway segment is close to one or multiple schools. The speed limit is twenty-five miles per hour when approaching or passing a school
building or the grounds while children are going to or leaving the school either during school hours or during the noon recess period.

California Vehicle Code (CVC) Section 40802 requires speed limits be justified by an Engineering and Traffic Survey conducted in accordance with
methods determined by the Department of Transportation. Speed limits are legally required to be established at the nearest five (5) mph increment to the
85th percentile speed. The 85th percentile speed is defined as that speed at or below which 85 percent of the traffic is moving. This means that a
segment with an 85th percentile speed of 27.4 miles per hour can be posted for 25 mph, while a segment with a critical speed of 27.5 mph must be posted
at 30 mph. However, Section 627 of the California Vehicle Code (CVC) stipulates that other factors besides the 85th percentile speed such as accident
records, roadside conditions, residential density along the roadway, as well as pedestrian and bicyclist safety can be considered when determining speed
limits.

In the northbound direction, the 85th percentile speed was measured at 3.0 mph over the posted limit, while in the southbound direction the 85th
percentile speed was measured at 1.0 mph over the posted speed limit.
Since the lower of the two 85th percentile speeds can be used to set the speed limit, the 85th percentile speeds in the southbound direction indicate an
initial speed of 40 mph which is equal to the current posted speed limit. Therefore, we recommend the City maintain the existing speed limit of 40 mph.

The observed 85th percentile speeds were 8.3 mph and 9.1 mph greater than the posted speed limit in the northbound and southbound directions respectively which
would initially require a posted speed limit of 35 mph.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway segment. Scotland Drive has no sidewalks or bicycle
facilities on either side of the roadway. No speed-related collisions have been reported on this section of Scotland Drive for the five-year period analyzed for this report.
According to the California MUTCD 2014 Edition, Revision 3, for cases in which the nearest five miles per hour increment of the 85th percentile speed would require a
rounding up, then the speed limit may be rounded down to the nearest five miles per hour increment below the 85th percentile speed, if no further reduction is used. The
85th percentile speeds in both northbound and southbound directions were rounded up to indicate an initial speed limit of 35 mph, which can be rounded down to 30
mph. However, due to the segment properties explained above such as residential nature of the segment and the lack of adequate bicycle and pedestrian facilities, we
recommend that the City maintain the current speed limit of 25 mph.

In the eastbound direction the 85th percentile speed was measured at 7.0 mph over the posted limit, while in the westbound direction the 85th percentile
speed was measured at 6.4 mph over the posted speed limit. The 85th percentile speeds would initially indicate raising the speed limit to 30 mph.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway segment. Seagull Way has sidewalks on
the west side of the street, with inconsistent sidewalks on the east side of the street. There are no bicycle facilities on either side of the roadway.
Additionally based on the CVC (CVC 40802 (b)) and the existing roadway geometries, this segment of Seagull Way qualifies as a local street with a prima
facie speed of 25 mph. No speed-related collisions have been reported for this segment of Seagull Way for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five
miles per hour below the limit established by the observed 85th percentile speeds. Therefore, due to the residential nature of Seagull Way and lack of
adequate pedestrian/ bicycle facilities, we recommend that the City maintain current speed limit of 25 mph.

Sobey Road is a winding local road that fronts private residents. The roadway width of the roadway varies between 20 and 40 feet. In terms of pedestrian
and bicycle safety, Sobey Road does not provide any bike lanes or any continuous sidewalks. No speed-related collisions have been reported for this
segment of Sobey Road for the five-year period analyzed.
Based on the segment properties explained above and in accordance with CVC Section 627, the City has the authority to establish the speed limit at five
