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 61 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 enforced by California law. Specifically,
roadway segments were analyzed in more detail where the 85th percentile speed exceeds the posted speed limit
by 2.5 miles per hour (mph) or more to determine the adequacy of the posted speed limit. Table 1 summarizes
the posted speed limit and observed 85th percentile speeds of the study roadway segments and highlights those
segments where the 85th percentile speeds exceeded the posted speed limit by 2.5 mph or more.
Overall, the observed 85th percentile speeds have increased slightly as compared to the data from the 2006 Speed
Survey. Speeds have increased on 31 of the 61 roadway segments, while speeds decreased on the remaining 30
segments. The observed 85th percentile speeds on the following 15 roadway segments indicated that the speed
limit should be 10 mph higher than the posted limit without considering other factors:
• Beaumont Avenue from Herriman Avenue to Glasgow Drive
• Bohlman Road from Southerly City Limit to Sixth Street
• Braemar Drive from Howen Drive to Scotland Drive
• Chester Avenue from Allendale Avenue to Ten Acres Road
• Cumberland Drive from Cox Avenue to Scotland Drive
• Glen Brae Drive from Scotland Drive to Cox Avenue
• Herriman Avenue from Saratoga - Sunnyvale Avenue to Saratoga Avenue
• Mendelsohn Lane from Saratoga -Los Gatos Road to Saratoga -Los Gatos Road
• Mount Eden Road from Pierce Road to Westerly City Limits
• Pierce Road from Highway 9 to Mount Eden Road
• Pierce Road from Mount Eden Road to Surrey Lane
• Pierce Road from Surrey Lane to Saratoga - Sunnyvale Road
• Prospect Road from Lawrence Expressway to Easterly City Limit

However, 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. When these factors are incorporated into the speed survey evaluation, we
recommend that the existing speed limits be maintained on all study roadway segments in the City of Saratoga.
Additionally, we recommend that the City continue to monitor speeds on the following five roadway segments
and implement traffic calming measures as needed to at least maintain and possibly decrease the 85th percentile
speeds:
• Allendale Avenue from Chester Avenue to Quito Road
• Mt. Eden Road from Pierce Road to the Westerly City Limit
• Pierce Road from Highway 9 to Mount Eden Road

INTRODUCTION
This report presents the speed survey analysis completed in the City of Saratoga, California. This study analyzes
the sufficiency of posted speed limits on various 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. Specifically, roadway segments where the 85th percentile speed exceeds
the posted speed limit by 2.5 miles per hour (mph) or more are analyzed in more detail to determine the
adequacy of the posted limit.

SPEED SURVEY ANALYSIS
This section represents the results of a speed survey conducted in Saratoga in April and May 2013. 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. 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 61 roadway segments analyzed for the 2013 Saratoga Speed
Survey.
DATA COLLECTION
Speed survey data was collected on selected street sections in which traffic speeds, traffic volumes, streets width
or other significant factors were different from adjacent sections. Speed surveys were conducted in April and May
2013 at sixty -one (61) locations within the City of Saratoga. Automated machine equipment was used to capture
existing average daily traffic (ADT) volumes. Per guidelines from the MUTCD, speeds for most 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 speed surveys are indicated in Figure 1 and
correspond with the location number indicator for each roadway segment. Table 1 summarizes the posted speed
limit and observed 85th percentile speeds of the study roadway segments. Figure 3 graphically compares the 85th
percentile speeds to the posted speed limit. Figure 4 shows the locations of the observed 85th percentile speeds.
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 2013 California Vehicle Code (CVC) defined the California Speed Laws. Relevant
sections of the CVC to determine speed limits in local jurisdiction are discussed below.

City of Saratoga — DRAFT 2013 Speed Survey

PRIMA FACIE SPEED LIMITS
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 ally.
• 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 only be changed
based on an Engineering and Traffic Survey.
ENGINEERING AND TRAFFIC SURVEY
Section 22357(a) stipulates that local authorities can set speed limits greater than 25 mph if they on the basis of
an engineering and traffic survey determine 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 prima facie 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.
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 Determining Speed Limits
When conducting Engineering and Traffic Survey to establish speed limits, Section 21400 of the CVC requires that
local authorities round speed limits to the nearest be five mph increment to the 85th percentile speed of free -
flowing traffic, except:
1. The posted speed limit may be reduced by 5 mph from the nearest 5 mph increment of the 85th
percentile speed, based on guidelines from CVC Section 627 and 22358.5, or
2. In cases in which the speed limit needs to be rounded up to the nearest five miles per hour increment of
the 85thpercentile speed, local authority may decide to instead round down the speed limit to the lower
five miles per hour increment, but then 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.

/A
City of Saratoga — DRAFT 2013 Speed Survey
November 2013 - -
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.
Section 627 of the CVC stipulates that other factors besides the 85th percentile speed such as collision records,
roadside conditions, residential density along the roadway, as well as pedestrian and bicyclist safety can be
considered when determining speed limits. Appendix B contains the text of CVC 627 and describes in detail what
factors should be taken into consideration when establishing speed limits. A speed limit can be lowered by five (5)
mph to account for these special factors. Establishment of a speed limit of more than 5 mph below the 85th
percentile speed should be done only after careful consideration.
COLLISSION DATA
Collision data was obtained from the Statewide Integrated Traffic Records System (SWITRS) for the five -year
window between August 1, 2006 and August 30, 2011. Specifically, collision data where the primary collision factor
was related to speed were used to augment the analysis in this report. Figure 4 shows the locations and
frequencies of speed - related collisions for the five -year window analyzed.

ANALYSIS
This section of the report analyses in more detail those roadway segments where the 85th percentile speed
exceeds the posted speed limit by 2.5 mph or greater to determine the adequacy of the posted speed limit. Other
factors such as 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
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 3.0 mph over the posted speed limit. The posted
speed limit is 35 mph. Speed limits must be established at the nearest five mph increment to the 85th percentile
speed and be established the same in both directions. The lower of the two critical speeds can be used to
determine the speed limit, which in this case is also above 2.5 mph from the posted speed limit. No mid -block
speed - related collisions have been reported for this segment of Allendale Avenue for the five -year period
analyzed.
West Valley College is located on south side of this segment of Allendale Avenue, and is frequently used by
pedestrians and bicyclist for access to the school, as well as by residents. Additionally, this segment of Allendale
Avenue does not have sidewalks on either side of the roadway. The CVC gives cities the jurisdiction to establish
the speed limit five mph below the nearest five mph increment indicated by the 85th percentile speeds when
additional factors support such action. Thus, the speed limit should be maintained at 35 mph on this segment
due to pedestrian and bicycle activity on this roadway segment.
Segment 2. Allendale Avenue from Portos Court to Chester Avenue
The posted speed limit on Allendale Avenue is 35 mph. The 85th percentile speed measured in the eastbound
direction is 3.0 mph over the posted speed limit, while the westbound speed was measured 2.0 mph over the
posted speed limit. The lower of the two critical speeds can be used to determine the speed limit. Therefore, we
recommend that the speed limit be maintained at the current posted limit of 35 mph.
No mid -block speed - related collisions have been reported for this segment of Allendale Avenue for the five -year
period analyzed for this report.
Segment 3. Allendale Avenue from Chester Avenue to Quito Road
Speeds in excess of 9.0 mph and 8.0 mph over the posted speed limit of 25 mph were observed in the eastbound
and westbound directions, respectively. This is the only section of Allendale Avenue where the speed limit is set to
25 mph; the remaining sections of Allendale Avenue have a posted speed limit of 35 mph. The observed 85th
i!' 20
City of Saratoga — DRAFT 2013 Speed Survey
November 2013 - -
percentile speed indicates that the speed limit should be 35 mph. No mid -block speed - related collisions have
been reported on this segment of Allendale Avenue for the five -year period analyzed for this report.
In the quarter mile distance between Quito Road and Harleigh Drive there are 16 driveways fronting Allendale
Avenue. Therefore, under CVC the City has the authority to maintain a speed limit at five mph below the observed
85th percentile speeds (CVC 627). 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. Thus, we recommend that the City maintain the 25 mph speed
limit and the City shall continue to monitor this segment of Allendale Avenue.
Segment 4. Arroyo De Arguello from Comer Drive to Via Roncole
In the northbound direction the 85th percentile speed was measured at 7.2 mph over the posted limit, while in the
southbound direction the 85th percentile speed was measured at 7.9 mph over the posted speed limit. The posted
speed limit is 25 mph. Speed limits must be established at the nearest five mph increment to the 85th percentile
speed and be established the same in both directions. The lower of the two critical speeds can be used to
determine the speed limit. Thus the observed 85th percentile speeds would indicate that the speed limit should be
posted at 30 mph. No mid -block speed - related collisions have been reported for this segment of Arroyo De
Arguello for the five -year period analyzed.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Additionally, Arroyo De Arguello has discontinuous sidewalks
on the west side of the street and no bicycle facilities on either side of the roadway. Thus, we recommend that
the City not change the current speed limit of 25 mph due to the residential nature of Arroyo De Arguello.
Segment 5. Beaumont Avenue from Herriman Avenue to Glasgow Drive
Beaumont Avenue has a posted speed limit of 25 mph. The 85th percentile speeds were observed to be 8.3 mph
and 10.6 mph in excess of the posted speed limit in the north and southbound direction respectively. Speed limits
must be established at the nearest five mph increment to the 85th percentile speed and be established the same in
both directions. The lower of the two critical speeds can be used to determine the speed limit. Thus the observed
85th percentile speeds would indicate that the speed limit should be posted at 35 mph. No speed - related mid -
block collisions have been reported on this section of Beaumont Avenue for the five -year period analyzed for this
report.
r� 21
City of Saratoga — DRAFT 2013 Speed Survey
November 2013 ---jdW-� - -
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Additionally, Beaumont Avenue serves as a main access route
for Saratoga High School, and is frequently used by pedestrians and bicyclist for access to the school, as well as by
residents. Beaumont Avenue does not have sidewalks or designated bicycle facilities on either side of the roadway.
Thus, the speed limit should be maintained at 25 mph on this segment due the residential nature as well as
the pedestrian and bicycle activity on Beaumont Avenue.
Segment 6. Bohlman Road from Southerly City Limit to Sixth Street
Bohlman Road has a posted speed limit of 25 mph. The 85th percentile speeds were observed to be 10.1 mph and
9.2 mph in excess of the posted speed limit in the north and southbound direction respectively. Speed limits must
be established at the nearest five mph increment to the 85th percentile speed and be established the same in both
directions. The lower of the two critical speeds can be used to determine the speed limit. Thus the observed 85th
percentile speeds would indicate that the speed limit should be posted at 35 mph. On this section of Bohlman
Road, three speed - related mid -block collisions have been reported for the five -year period analyzed for this
report.
Bohlman Road is a narrow (20 feet) local and winding road with limited visibility at curves. This segment of
Bohlman Road has no sidewalks or pedestrian facilities. Given the roadway geometries the speed limit could
be set to 20 mph based on code in the CVC (CVC 22358.3) and we recommend that the City maintain the
existing speed limit of 25 mph.
Segment 7. Braemar Drive from Howen Drive to Scotland Drive
In the eastbound direction the 85th percentile speed was measured at 8.1 mph over the posted limit, while in the
westbound direction the critical speed was measured at 8.6 mph over the posted speed limit. The posted speed
limit is 25 mph. Speed limits must be established at the nearest five mph increment to the 85th percentile speed
and be established the same in both directions. Thus the observed 85th percentile speeds would indicate that the
speed limit should be posted at 35 mph. No mid -block speed - related collisions have been reported for this
segment of Braemar Drive for the five -year period analyzed.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Additionally, Braemar Drive has no sidewalks or bicycle
facilities on either side of the roadway. Thus, we recommend that the City not change the current speed limit
of 25 mph due to the residential nature as well as the pedestrian and bicycle activity on Braemar Drive.

Segment 8. Bucknall Road from Saratoga Avenue to Quito Road
The posted speed limit on this segment of Bucknall Road is 25 mph. In both the east and westbound direction the
85th percentile speed was measured at 7.0 mph over the posted limit. Speed limits must be established at the
nearest five mph increment to the 85th percentile speed and be established the same in both directions. Thus the
observed 85th percentile speeds would indicate that the speed limit should be posted at 30 mph. No mid -block
speed - related collisions have been reported for this segment of Bucknall Road for the five -year period analyzed
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Bucknall Primary School is located at the corner of Bucknall
Road and Paseo Presada Road, and a school crosswalk is located just west of the school on Bucknall Road
approximately 350 feet east of Saratoga Avenue. Additionally, this segment of Bucknall Road has discontinuous
sidewalks on the south sides of the roadway and no bicycle facilities on both sides of the roadway. Thus, the
speed limit should be maintained at 25 mph on this segment due the residential nature of Bucknall Road.
Segment 9. Canyon View Drive from Reid Lane to Toll Gate Road
The posted speed limit on this segment of Canyon View Drive is 25 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 4.5 mph over the posted speed limit. The posted speed limit is 25 mph. Speed
limits must be established at the nearest five mph increment to the 85th percentile speed and be established the
same in both directions. The lower of the two critical speeds can be used to determine the speed limit. Thus the
observed 85th percentile speeds would indicate that the speed limit should be posted at 30 mph. No mid -block
speed - related collisions have been reported for this segment of Canyon View Drive for the five -year period
analyzed.
Canyon View Drive is a narrow (20 feet) and winding, local road. This segment of Canyon View Drive has no
sidewalks or pedestrian facilities. Given the roadway geometries the speed limit could be set to 20 mph based
on code in the CVC (CVC 22358.3) and we recommend that the City maintain the existing speed limit of 25
mph.
Segment 10. Chateau Drive from Regan Lane to southern Argonaut Drive
In the eastbound direction the 85th percentile speed was measured at 3.4 mph over the posted limit, while in the
westbound direction the 85th percentile speed was measured at 4.3 mph over the posted speed limit. The posted
speed limit is 25 mph. Speed limits must be established at the nearest five mph increment to the 85th percentile
speed and be established the same in both directions. The lower of the two critical speeds can be used to
determine the speed limit. Thus the observed 85th percentile speeds would indicate that the speed limit should be

posted at 30 mph. No mid -block speed - related collisions have been reported for this segment of Chateau Drive
for the five -year period analyzed.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Argonaut Elementary School is located at the corner of
Chateau Drive and Shadow Mountain Drive, and a school crosswalk is located just north of the school on Chateau
Drive approximately 350 feet east of Argonaut Drive. Additionally, this segment of Bucknall Road has no sidewalks
or bicycle facilities. Thus, we recommend that the City maintain the current speed limit of 25 mph due to the
residential nature of Chateau Drive.
Segment 11. Chester Avenue from Allendale Avenue to Ten Acres Road
The posted speed limit on Chester Avenue is 25 mph. The 85th percentile speed survey at Chester Avenue between
Allendale Avenue and Ten Acres Road is 10.3 mph over the posted speed limit in the northbound and southbound
direction. This would typically require a posted limit of 35 mph. No mid -block speed - related collisions have been
reported for this segment of Chester Avenue for the five -year period analyzed for this report.
Since Chester Avenue is a narrow, 25 -foot wide residential street with no separate sidewalks or paths for
pedestrians or bicyclists, it warrants a reduction in the speed limit. Therefore, the speed limit should be
maintained at 25 mph to better accommodate all travel modes on this narrow winding roadway.
Segment 12. Chester Avenue from Ten Acres Road to Sobey Road
The 85th percentile speeds surveyed on this segment of Chester Avenue is 5.4 mph and 4.3 mph higher than the
posted speed limit in the northbound and southbound directions, respectively. Thus the observed 85th percentile
speeds would indicate that the speed limit should be posted at 30 mph. No mid -block speed - related collisions
have been reported for this segment of Chester Avenue for the five -year period analyzed for this report.
This section of Chester Avenue is narrow and winding residential roadway with no separate sidewalks or paths for
pedestrians or bicyclists. Therefore, under the CVC, the speed limit can be established at five mph below the
speed limit indicated by 85th percentile speeds. Thus, the speed limit should be maintained at 25 mph on this
segment of Chester Avenue.
Segment 13. Cox Avenue from Saratoga - Sunnyvale Road to the UPRR Crossing
The posted speed limit on Cox Avenue is 35 mph but the eastbound and westbound 85th percentile speeds were
both surveyed at 5.0 mph greater than the posted speed limit. Speed limits must be established at the nearest five
mph increment to the 85th percentile speed and be established the same in both directions. Thus the observed
M24
/A
City of Saratoga - DRAFT 2013 Speed Survey
November 2013 - — -
85th percentile speeds would indicate that the speed limit should be posted at 40 mph. No speed - related
collisions have been reported on this segment of Cox Avenue for the five -year period analyzed for this report.
Joe's Trail crosses this segment of Cox Avenue just west of the UPRR crossing and serves as an important link for
pedestrians and bicyclists. Maintaining reasonable travel speeds is critical to providing an improved environment
for bicyclists and pedestrians. Additionally, the posted speed limit on the Cox Avenue segment east of the railroad
tracks is 35 mph as justified by the 85th percentile speeds on that segment. To enhance the pedestrian and
bicycle safety and to maintain continuity in the corridor, we recommend that the speed limit remain at 35
mph on this segment of Cox Avenue.
Segment 14. Cox Avenue from the UPRR Crossing to Saratoga Avenue
Vehicles were observed traveling 5.0 mph in both directions in excess of the posted speed limit of 35 mph. The
observed 85th percentile speeds would typically require that the speed limit be raised to 40 mph. One speed -
related mid -block collision has been reported on this section of Cox Avenue for the five -year period analyzed for
this report.
This segment of Cox Avenue has sidewalks and bike lanes in both directions. However, a marked uncontrolled
crosswalk is provided at Miller Avenue, which serves as a major connection point between the neighborhoods
north and south of Cox Avenue. The Miller Avenue intersection is not controlled, and this connection point
attracts pedestrians traveling to Brookglen Park, Kevin Moran Park, and the elementary and middle school located
north of Cox Avenue. Therefore, we recommend that the City maintain the current speed limit of 35 mph to
enhance pedestrian and bicycle travel and maintain reasonable crossing travel speeds approaching the
crosswalk.
Segment 15. Cox Avenue from Saratoga Avenue to Paseo Presada
The 85" percentile speed on this section of Cox Avenue with four travel lanes is 8.0 and 7.0 mph more than the
posted speed limit of 25 mph in the eastbound and westbound directions, respectively. These measurements
would require posting a limit of 30 mph based on CVC without any consideration for pedestrian /bicycle safety and
other neighborhood issues. One mid -block speed - related collision has been reported on this segment of Cox
Avenue between 2006 and 2010.
This section of Cox Road is currently posted for 25 mph due to the proximity of the existing shopping center
(including Gene's Market) on one side of the street and elderly residences and a pre - school on the other side of
the street. A mid -block crosswalk is located approximately halfway between Saratoga Avenue and Paseo Presada
to guide pedestrians, especially elderly residents. In May 2013, after the speed surveys were conducted, the City of
Saratoga enhanced the mid -block crosswalk, by raising the crosswalk and providing pedestrian activated in-
roadway warning lights. In addition, El Quito Park is located on Paseo Presada north of Cox Avenue and is also a
r� 25

pedestrian attractor. Due to these factors, we recommend maintaining the speed limit at 25 mph on this
stretch.
Segment 16. Cumberland Drive from Cox Avenue to Scotland Drive
The posted speed limit on this segment of Cumberland Drive is 25 mph. In the northbound direction the 85th
percentile speed was measured at 9.2 mph over the posted limit, while in the southbound direction the 85th
percentile speed was measured at 9.4 mph over the posted speed limit. Thus the observed 85th percentile speeds
would indicate that the speed limit should be posted at 35 mph. No mid -block speed - related collisions have been
reported for this segment of Cumberland Drive for the five -year period analyzed.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Additionally, Cumberland Drive has no sidewalks or bicycle
facilities on either side of the roadway. Thus, we recommend that the City maintain the current speed limit of
25 mph due to the residential nature as well as the pedestrian and bicycle activity on Cumberland Drive.
Segment 17. Farwell Avenue from Fruitvale to Saratoga -Los Gatos Road
The posted speed limit on Farwell Avenue is 25 mph. The 85th percentile speeds on Farwell Avenue exceed the
posted speed limit by 9.4 mph (northbound) and 7.2 mph (southbound). The posted speed limit is 25 mph. Speed
limits must be established at the nearest five mph increment to the 85th percentile speed and be established the
same in both directions. The lower of the two critical speeds can be used to determine the speed limit. Thus, the
observed 85th percentile speeds would typically require that the speed limit be raised to 30 mph. No mid -block
speed - related collisions have been reported between 2008 and 2011.
Farwell Avenue is a 0.6 -mile long local road that bends at ninety degrees at its halfway point. Given the local
nature of Farwell Avenue and its narrow width the City has the authority under the CVC to maintain a speed limit
at five mph below the observed 85th percentile speeds. Additionally, Farwell Avenue does not include sidewalks or
bicycle lanes, which forces pedestrians and cyclists to use the roadway with vehicles. We recommend that the
City maintain the existing posted speed limit of 25 mph due to the residential nature of Farewell Avenue.
Segment 18. Fruitvale Avenue from Saratoga -Los Gatos Road to Burgundy Way
The observed 85th percentile speeds surveyed on this segment of Fruitvale Avenue are 42.0 mph in the
northbound and 41.0 mph southbound direction. The posted speed limit on Fruitvale Avenue is 35 mph, resulting
in excess speeds in northbound and southbound of 7.0 mph and 6.0 mph, respectively. Since the lower of the two
critical speeds can be used to determine the appropriate speed limit, the 85th percentile in the southbound
M26

direction indicates a speed limit of 40 mph. One speed - related mid -block collision has been reported on this
section of Fruitvale Avenue for the five -year period analyzed for this report.
However, this section of Fruitvale Avenue does not provide continuous bicycle and pedestrian facilities on the
roadway. Based on this information and allowances under the CVC, the City has the authority to maintain the
speed limit at five mph below the 85th percentile speed. Therefore, we recommend that the City maintain the
existing speed limit of 35 mph.
Segment 19. Fruitvale Avenue from Burgundy Way to Allendale Avenue
On this study roadway segment the 85th percentile speeds were observed to be 6.0 mph over the posted speed
limit of 35 mph in both directions. This would initially indicate the need for a speed limit of 40 mph. A review of
collision data for this roadway segment shows that there have been four collisions where the primary collision
factor was speed.
Several factors support maintaining the current speed limit of 35 mph on this segment of Fruitvale Avenue.
Redwood Middle School and West Valley College are located along this roadway segment of Fruitvale Avenue and
attract a substantial level of pedestrian and bicycle activity throughout the day. Additionally, the posted speed
limit on Fruitvale Avenue north and south of this segment is 35 mph as supported by the 85th percentile speeds
on those two roadway segments. To enhance the pedestrian and bicycle environment per CVC and to
maintain speed limit continuity in this corridor, we recommend that the posted speed limit remain at 35
mph.
Segment 20. Fruitvale Avenue from Allendale Avenue to Saratoga Avenue
The observed 85th percentile speed surveys on this 35 mph segment of Fruitvale Avenue show an excess of 3.0
mph in both directions of. The observed 85th percentile speeds would typically indicate raising the speed limit
from 35 to 40 mph. Four speed - related mid -block collisions have been reported on this section of Fruitvale
Avenue for the five -year period analyzed for this report
This section of Fruitvale Avenue has significant numbers of pedestrian and bicycle activity, due to the proximity of
the City Hall and Community Center facilities, Redwood Middle School, West Valley College, and other community
attractions. Additionally, this section of Fruitvale Avenue has narrow sidewalks and sub - standard bike lanes on
both sides of the roadway. Therefore, the City has the authority under the CVC to maintain the speed limit at
five mph below the 85th percentile speed, and the City should maintain the existing speed limit of 35 mph.
Segment 21. Glasgow Drive from Argonne Drive to Cumberland Drive
In the northbound direction the 85th percentile speed was measured at 7.4 mph over the posted limit, while in the
southbound direction the 85th percentile speed was measured at 7.9 mph over the posted speed limit. The posted
M27

speed limit is 25 mph. The 85th percentile speeds would indicate raising the speed limit to 30 mph. No mid -block
speed - related collisions have been reported for this segment of Glasgow Drive for the five -year period analyzed.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Further, Glasgow Drive has no sidewalks or bicycle facilities on
either side of the roadway. Thus, we recommend that the City maintain current speed limit of 25 mph due to
the residential nature of Glasgow Drive.
Segment 22. Glen Brae Drive from Scotland Drive to Cox Avenue
The posted speed limit on this segment of Glen Brea Drive is 25 mph. The observed 85th percentile speeds were
9.0 mph and 8.1 mph greater than the posted speed limit in the northbound and southbound directions
respectively. This would initially require a posted limit of 35 mph. No speed - related mid -block collisions have been
reported on this section of Glen Brae Drive for the five -year period analyzed for this report.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Additionally, Glen Brae Drive has no sidewalks or bicycle
facilities on either side of the roadway. Thus, we recommend that the City maintain the current speed limit of
25 mph due to the residential nature as well as the pedestrian and bicycle activity on Glen Brae Drive.
Segment 23. Harleigh Drive from Allendale Avenue to Fortuna Court
The posted speed limit on this segment of Harleigh Drive is 25 mph. The observed 85th percentile speeds were 4.1
mph and 3.4 mph greater than the posted speed limit in the eastbound and westbound directions, respectively.
This would initially require a posted limit of 30mph. No speed - related mid -block collisions have been reported on
this section of Glen Brae Drive for the five -year period analyzed for this report.
Under CVC, the City has the authority to establish the speed limit at five mph below the 85th percentile speed if
more than 16 housing units front the roadway within a distance of a quarter of a mile. This section of Harleigh
Drive meets this requirement. Thus, the initial limit of 30 mph based on the observed 85th percentile speeds can
be reduced up to 5 mph given the residential nature of the roadway, lack of bicycle lanes, and the discontinuous
sidewalks. Thus, we recommend that the City maintain the 25 mph speed limit on Harleigh Drive due to its
residential nature.
Segment 24. Herriman Avenue from Saratoga - Sunnyvale Avenue to Saratoga Avenue
The 85th percentile speed surveys on Herriman Avenue are 8.0 mph (eastbound) and 7.0 mph (westbound) in
excess of the 25 mph posted speed limit. Since, the lower of the two critical speeds can be used to determine the
M28
/A
City of Saratoga — DRAFT 2013 Speed Survey
November 2013
speed limit, this would indicate that the speed limit should be increased to 30 mph. One speed - related mid -block
collision has been reported on this section of Herriman Avenue for the five -year period analyzed for this report.
Saratoga High School is located at the corner of Saratoga - Sunnyvale Avenue and Herriman Avenue, and primary
school access is provided by driveways on Herriman Avenue. A sidewalk or path is only provided on the south side
of Herriman Avenue, so some residents on the north side may walk in or near the travel lane. Based on the
proximity to the school, it is recommended that the speed limit on Herriman Avenue be maintained at 25
mph, which is five mph below the speed limit indicated by the observed 85th percentile speeds.
Segment 25. Horseshoe Drive from eastern SR 9 to western SR 9
In the northbound direction the 85th percentile speed was measured at 6.1 mph over the posted limit, while in the
southbound direction the 85th percentile speed was measured at 6.5 mph over the posted speed limit. The posted
speed limit is 25 mph. Speed limits must be established at the nearest five mph increment to the 85th percentile
speed and be established the same in both directions. The lower of the two critical speeds can be used to
determine the speed limit. Thus the observed 85th percentile speeds would indicate that the speed limit should be
posted at 30 mph. No mid -block speed - related collisions have been reported for this segment of Horseshoe Drive
for the five -year period analyzed.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below

facilities on either side of the roadway. Thus, we recommend that the City maintain the current speed limit of
25 mph due to the residential nature of Horseshoe Drive.
Segment 26. Johnson Avenue from Prospect Boulevard to Northerly City Limits
The speed limit on this segment of Johnson Avenue is 35 mph and the 85th percentile speeds were observed at 3.0
mph and 2.0 mph above the posted speed limit in the northbound and southbound directions, respectively. Since
the lower of the two critical speeds can be used to set the speed limit, the 85th percentile speeds in the
northbound direction indicate an initial speed limit of 35 mph. Therefore, the City should maintain the existing
speed limit of 35 mph. No mid -block speed - related collisions have been reported between 2008 and 2011.
Segment 27. McFarland Avenue from Saratoga Avenue to Devon Avenue
The posted speed limit on this segment of McFarland Avenue is 25 mph. In the northbound direction the 85th
percentile speed was measured at 2.0 mph below the posted limit, while in the southbound direction the 85th
percentile speed was measured at 0.9 mph over the posted speed limit. This indicates that the speed limit should
remain posted at 25 mph and we recommend that the City maintain the current speed limit of 25 mph. No

mid -block speed - related collisions have been reported for this segment of McFarland Avenue for the five -year
period analyzed.
Segment 28. Mendelsohn Lane from Saratoga -Los Gatos Road to Saratoga -Los Gatos Road
The speed survey results show that vehicles are traveling in excess speeds of 8.1 and 10.8 mph over the posted
speed limit of 25 mph in the east and westbound directions, respectively. This would require a change in the
posted limit to 35 mph. No mid -block speed - related collisions have been reported for Mendelsohn Lane for the
five -year period analyzed for this report.
Mendelsohn Lane meets the state requirements for a prima facie speed of 20 mph due to its narrow roadway
(22358.3 CVC). Additionally, no sidewalks or bicycle facilities are provided on Mendelsohn Lane. This roadway is
relatively short (0.5 miles) and includes a 90- degree turn at the halfway point. Therefore, in consideration of the
roadway geometries it is recommended that the City maintain the existing posted speed limit of 25 mph.
Segment 29. Montalvo Road from Saratoga -Los Gatos Road to Villa Montalvo Entrance
The posted speed limit on Montalvo Road is 25 mph. The northbound 85th percentile speed was observed at 8.1
mph over the posted speed limit in the northbound direction and 6.1 mph in the southbound direction. Since the
lower of the two critical speeds can be used to set the speed limit, the 85th percentile speeds in the southbound
direction requires an initial posted speed limit of 30 mph. No mid -block speed - related collisions have been
reported for Montalvo Road Lane for the five -year period analyzed for this report.
Montalvo Road is a residential street that connects Saratoga -Los Gatos Road with Villa Montalvo. The roadway
width varies from 20 feet to 40 feet, includes numerous curves and grade changes, and does not include any
sidewalks or formal paths. Under CVC, the City can maintain the speed limit at five mph below the limit indicated
by the 85th percentile speeds when existing conditions justify the reduction. Therefore, we recommend that the
City maintain the current posted speed limit of 25 mph.
Segment 30. Mount Eden Road from Pierce Road to Westerly City Limits
Mount Eden Road has a posted speed limit of 25 mph. The 85th percentile speeds were observed to be 39.6 mph
and 39.1 mph in the northbound and southbound directions, respectively. This results in speeds of approximately
14.6 mph and 14.1 mph in excess of the existing posted speed limit in the north and southbound directions,
respectively. These speeds would require an initial posted limit of 40 mph. One mid -block speed - related collision
has been reported on this section of Mount Eden Road for the five -year period analyzed for this report.
Mount Eden Road is a narrow (20 feet) local and winding road with limited visibility at curves. This segment of
Mount Eden Road is frequently used by bicyclists and pedestrian, but no sidewalks or pedestrian facilities. Given
the roadway geometries the speed limit could be set to 20 mph based on code in the CVC (CVC 22358.3) and we
M30
/A
City of Saratoga — DRAFT 2013 Speed Survey

recommend that the City maintain the existing speed limit of 25 mph. The City should monitor this
segment of Mount Eden Road for possible traffic calming measures to reduce the 85`h percentile speeds.
Segment 31. Paseo Presada from Bucknall Road to Dundee Avenue
The posted speed limit on this segment of Paseo Presada is 25 mph. In both the northbound and southbound
directions the 85th percentile speeds were measured at 3.0 mph over the posted limit. Thus the observed 85th
percentile speeds would indicate that the speed limit should be posted at 30 mph. No mid -block speed - related
collisions have been reported for this segment of Paseo Presada for the five -year period analyzed.
Bucknall Elementary School is located at the corner of Bucknall Road and Paseo Presada, with mid -block school
crosswalk located approximately 150 feet south of the intersection. There are discontinuous sidewalks and no
bicycle facilities on either side of Paseo Presada. Additionally based on the CVC (CVC 40802 (b)) and the existing
roadway geometries, this segment of Paseo Presada qualifies as a local street with a prima facie speed of 25 mph.
Thus, we recommend that the City maintain the current speed limit of 25 mph due to the residential nature
of Paseo Presada.
Segment 32. Pierce Road from Highway 9 to Mount Eden Road

exceed the posted speed limit by 11.5 mph in the northbound and 12.4 mph in the southbound direction. This
requires an initial posted limit of 35 mph. One mid -block speed - related collision has been reported for this
segment of Pierce Road for the five -year period analyzed.
Pierce Road is a winding roadway with limited visibility at curves that has narrow shoulders, and no sidewalks are
provided. Regardless, bicyclists and pedestrians frequently use Pierce Road for recreational activities. Given the
lack of pedestrian and bicycle facilities and limited sight distance at numerous locations, we recommend that the
City maintain the current speed limit of 25 mph and that the City continue to monitor this section of Pierce
Road for additional traffic calming measures as appropriate.
Segment 33. Pierce Road from Mount Eden Road to Surrey Lane
The posted speed limit is 25 mph. The 85th percentile speed surveys on this section were in excess of 7.9 mph of
the posted limit in both the northbound and southbound directions. This data would typically indicate posting a
speed limit of 35 mph. Two mid -block speed - related collisions have been reported for this segment of Pierce
Road for the five -year period analyzed for this report.

reduced by 5 mph and we recommend maintaining the posted speed limit of 30 mph.
Segment 35. Prospect Road from Westerly City Limit to Stelling Road
The speed survey results show that vehicles are traveling at 6.3 and 5.4 mph in excess of the posted speed limit of
25 mph in the eastbound and westbound directions, respectively. This data would require posting a speed limit of
30 mph. No mid -block speed - related collisions have been reported for this segment of Prospect Road for the five -
year period analyzed for this report.
This is a narrow roadway that has narrow shoulder striping and no sidewalks. Pedestrians and bicyclists both use
this roadway to access to Fremont Older County Park at the end of the road. Therefore, increased speeds would
potentially represent an increase safety concern. It is not recommended that the speed limit be raised to 30 mph
as the observed speeds indicate on this section of Prospect Road. We recommend that the City maintain the
current speed limit of 25 mph.
Segment 36. Prospect Road from Stelling Road to Saratoga - Sunnyvale Road
On this section of Prospect Road the posted speed limit is 35 mph. The 85th percentile speeds were observed to
be 3.0 mph in excess of the posted speed limit in both directions and would initially indicate a speed limit of 40
mph. One mid -block speed - related collision has been reported for this segment of Prospect Road for the five -year

The 85th percentile speed surveys on this section of Saratoga - Sunnyvale Road are 43.0 mph in the northbound
direction and 42.0 mph in the southbound direction. The posted speed limit is 40 mph, resulting in excess speeds
in both the northbound and southbound direction of 3.0 mph and 2.0 mph in the north and southbound
directions, respectively. Since the lower of the two 85th percentile speeds can be used to set the new speed limit,
the posted limit should remain at 40 mph. Therefore, it is recommended that the City maintain the current
speed limit of 40 mph. Four mid -block speed - related collisions have been reported on this segment of Saratoga-
Sunnyvale Road.

Segment 54. Saratoga - Sunnyvale Road from Verde Vista Lane to Blauer Drive
The 85t" percentile speed surveys on this section of Saratoga - Sunnyvale Road are 47.0 mph in the northbound
direction and 45.0 mph in the southbound direction. The posted speed limit is 40 mph, resulting in excess speeds
in both the northbound and southbound direction of 5.0 and 7.0 mph. These observed speeds would indicate a
speed limit of 45 mph. Two mid -block speed - related collisions have been reported on this segment of Saratoga -
Sunnyvale Road.
This section of Saratoga - Sunnyvale Road begins at the northern end of Saratoga High School, and therefore is
close to a school zone. Additionally, this segment of Saratoga - Sunnyvale Road is nearly one mile long and has
several unmarked legal crosswalks. Signalized crosswalks are provided only at Blauer Drive. Therefore, it is
recommended that the City maintain the current speed limit of 40 mph, which is five mph below the speed
limit indicated by the observed critical speeds.
Segment 55. Saratoga - Sunnyvale Road from Blauer Drive to Union Pacific Rail Road
On this section of Saratoga - Sunnyvale Road speed limits were observed at approximately 44.0 mph in the
northbound direction and 43.0 mph in the southbound direction. The posted speed limit is 40 mph. Since vehicles
are traveling in excess of 2.5 mph of the posted speed limit, the critical speeds indicate that the speed limit should
be posted at 45 mph. No mid -block speed - related collisions have been reported on this segment of Saratoga -
Sunnyvale Road.
A shopping center is located at the corner of Saratoga - Sunnyvale Road and Blauer Drive and an elementary
school is located just east of Saratoga - Sunnyvale Road. Additionally, since it is recommended that the speed limit
be maintained at 40 mph at the two roadway segments of Saratoga - Sunnyvale Road south of this segment, we
recommend that the speed limit on this section of Saratoga - Sunnyvale Road be maintained at 40 mph to
provide a consistent speed limit on Saratoga - Sunnyvale Road.
Segment 56. Saratoga - Sunnyvale Road from Union Pacific Railroad to Prospect Road
On this section of Saratoga - Sunnyvale Road speed limits were observed at approximately 40.0 mph in the
northbound direction and 42.0 mph in the southbound direction. The posted speed limit is 40 mph. Since neither
direction of travel is in excess of 2.5 mph of the posted speed limit, the critical speeds indicate that the speed limit
should remain at 45 mph. Three mid -block speed - related collisions have been reported on this segment of
Saratoga - Sunnyvale Road.
Due to the critical speeds, we recommend that the speed limit on this section of Saratoga - Sunnyvale Road
be maintained at 40 mph.

Segment 57. Scotland Drive from Saratoga Avenue to Cumberland Drive
The posted speed limit on this segment of Scotland Drive is 25 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 8.6 mph over the posted speed limit. Thus the observed 85th percentile speeds
would indicate that the speed limit should be posted at 35 mph. No mid -block speed - related collisions have been
reported for this segment of Scotland Drive for the five -year period analyzed.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Scotland Drive has no sidewalks or bicycle facilities on either
side of the roadway. Thus, we recommend that the City not change the current speed limit of 25 mph due to
the residential nature as well as pedestrian and bicycle activity on Scotland Drive.
Segment 58. Seagull Way from Saratoga - Sunnyvale Road to Cox Avenue
The posted speed limit on this segment of Seagull Way is 25 mph. In the eastbound direction the 85th percentile
speed was measured at 4.5 mph over the posted limit, while in the westbound direction the 85th percentile speed
was measured at 6.3 mph over the posted speed limit. Thus the observed 85th percentile speeds would indicate
that the speed limit should be posted at 30 mph. No mid -block speed - related collisions have been reported for
this segment of Seagull Way for the five -year period analyzed.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. 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. Thus, we recommend that the City maintain the
current speed limit of 25 mph due to the residential nature of Seagull Way.
Segment 59. Sobey Road from Northerly Quito Road to Southerly Quito Road
The posted speed limit on Sobey Road is 30 mph and the 85th percentile speeds were observed to exceed the
posted speed limit by 8.0 mph in the northbound and 7.6 mph in the southbound direction. The critical speeds
indicate that the speed limit should be posted at 40 mph. No mid -block speed - related collisions have been
reported between 2008 and 2011.
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
M39

City of Saratoga — DRAFT 2013 Speed Survey

any continuous sidewalks. Due to the nature of the roadway it is not recommended that the speed limit be
increased to 40 mph as the observed 85th percentile speed would indicate. Rather, it is recommended that the
City maintain the current posted speed limit of 30 mph.
Segment 60. Toll Gate Road from Big Basin Way to Saratoga Heights Drive
The posted speed limit on this segment of Toll Gate Road Avenue is 25 mph. The 85th percentile speed was
measured at 12.8 mph over the posted limit in the northbound direction and 9.7 southbound directions. Thus the
observed 85th percentile speeds would indicate that the speed limit should be posted at 35 mph. No mid -block
speed - related collisions have been reported for this segment of Toll Gate Road for the five -year period analyzed
Toll Gate Road is a narrow (24 feet) and winding local road and meets the state requirements for a prima facie
speed of 20 mph due to its narrow roadway (22358.3 CVC). Additionally, no sidewalks or bicycle facilities are
provided on Toll Gate Road. Therefore, in consideration of the roadway geometries we recommend that the
City maintain the existing speed limit of 25 mph on Toll Gate Road.
Segment 61. Woodside Drive from Bellwood Drive to Prospect Road
The posted speed limit on this segment of Woodside Drive is 25 mph. In the northbound direction the 85th
percentile speed was measured at 5.6 mph over the posted limit, while in the southbound direction the 85th
percentile speed was measured at 4.3 mph over the posted speed limit. Thus the observed 85th percentile speeds
would indicate that the speed limit should be posted at 30 mph. No mid -block speed - related collisions have been
reported for this segment of Woodside Drive for the five -year period analyzed.
More than 16 separate dwelling units exist on both sides of the roadway within a quarter mile along this roadway
segment. In accordance with the CVC 627, the City has the authority to establish the speed limit at five mph below
the limit established by the observed critical speed. Additionally, Woodside Drive has no sidewalks or bicycle
facilities on either side of the roadway. Thus, we recommend that the City maintain the current speed limit of
25 mph due to the residential nature of Woodside Drive.

COMPARISON OF 2013 SPEEDS TO 2006 SURVEY
This section of the report compares the observed 85th percentile speeds collected for this report, to those
observed in the 2006 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 2006 and 2013 speed data and Figure 6
graphically shows the difference in the observed 85th percentile speeds between year 2006 and year 2013 data
(2013 minus 2006).
As shown on Figure 6, about half of the 85th percentile speeds have increased as compared to data from 2006. On
the following 31 roadway segments the 85th percentile speeds increased in one or both directions as compared to
data collected in 2006.

On the remaining 30 roadway segments the 85th percentile speeds either decreased or were unchanged compared
to the 2006 data.
The greatest change in the 85th percentile speed between 2006 and 2013 occurred on Sarahills Drive (Segment 45)
with a 13 mph increase in the eastbound direction. The speeds on Sarahills however, only increased by 5 mph in
the westbound direction. The largest decreases in speed occurred on McFarland Avenue and Prospect Road
(between Miller Avenue and Lawrence Expressway), whose speeds decreased by 6 and 5 mph respectively.
For those segments where the 85th percentile speeds increases over the year 2006 data, the average increase was
approximately by 2.5 mph. Conversely, the 85th percentile speeds decreased on average by about 1.8 mph for
those segments where the speeds decreased as compared to 2006.

November 2013 -- -
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 7 graphically presents the ADT for the 61 study roadway segments analyzed and compares
those to the data collected in 2006.
All but five of the roadway segments analyzed in this report serve less than 25,000 ADT. The following five
roadway segments in the City serve between 25,000 and 40,000 ADT:
• Prospect Road from Lawrence Expressway to the Easterly City Limit (25,300 ADT)
• Saratoga Avenue from Fruitvale Avenue to Dagmar Drive (34,200 ADT)
• Saratoga Avenue from Vineyard Lane to Cox Avenue (37,100 ADT)
• Saratoga Avenue from Cox Avenue to Northerly City Limit (31,800 ADT)
• Saratoga - Sunnyvale Road from Union Pacific Railroad to Prospect Road (26,600 ADT)
Saratoga Avenue is a major arterial in the City of Saratoga and provides direct access to State Route 85 and the
downtown village; therefore the higher volumes on this roadway are expected. Prospect Road is also a major
arterial in the City and provides east -west access from S De Anza Boulevard to Lawrence Expressway and Saratoga
Avenue. Similarly, Saratoga - Sunnyvale Road is a major arterial that provides north -south connectivity towards the
western border of the City of Saratoga.

City of Saratoga - DRAFT 2013 Speed Survey
November 2013 - - -
SUMMARY AND CONCLUSION
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 61 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 enforced by California law. Specifically,
roadway segments where the 85th percentile speed exceeds the posted speed limit by 2.5 miles per hour (mph) or
more were analyzed in more detail to determine the adequacy of the posted speed limit.
Based on the analysis in this report, we recommend that the City of Saratoga maintain the existing speed limits,
and that the City monitor speeds on the following three roadway segments and implement traffic calming
measures to maintain and possibly decrease the 85th percentile speeds:
• Allendale Avenue from Chester Avenue to Quito Road
• Mt. Eden Road from Pierce Road to the Westerly City Limit
• Pierce Road from Highway 9 to Mount Eden Road
FURTHER RECOMMENDATIONS
Based on CVC Section 40802, city roadways not defined as a collector or arterial street are classified as a local
roadway with a prima facie speed limit of 25 mph if the local roadway primarily provides access to abutting
residential property and meets the following three conditions:
a) Roadway width of not more than 40 feet
b) Not more than one -half of a mile of uninterrupted length. Interruptions include official traffic control
signals as defined in CVC Section 445 and include among other control devices stop -signs and signals.
c) Not more than one traffic lane in each direction
The following roadway segments analyzed in the 2013 Saratoga Speed Survey qualify as local roadways as defined
by CVC Section 40802 and should be posted with a prima facie speed of 25 mph:
• Beaumont Avenue from Herriman Avenue to Glasgow Drive
Bucknall Road from Saratoga Avenue to Quito Road
• Chateau Drive from Regan Lane to Southern Argonaut Drive

City of Saratoga - DRAFT 2013 Speed Survey
November 2013 - - - -
• Cumberland Drive from Cox Avenue to Scotland Drive
• Glasgow Drive from Argonne Drive to Cumberland Drive
• Harleigh Drive from Allendale Avenue to Fortuna Court
• Horseshoe Drive from Eastern SR 9 to Western SR 9
• McFarland Avenue from Saratoga Avenue to Devon Avenue
• Paseo Presada from Bucknall Road to Dundee Avenue
• Saratoga Creek Drive from Cox Avenue to Kosich Drive

We recommend that the City of Saratoga amend section article 9- 30.060 to exclude the roadway segments listed
above from future speed surveys. This will set the prima facie speed on the roadway segments listed above to 25
mph and they would not need to be included in the next update to the Citywide Speed Survey.
