TITLE: ESTABLISH A PRIMA FACIE
SPEED LIMIT UPON CANNON ROAD
FROM EL CAMINO REAL TO COLLEGE BOULEVARD
RECOMMENDED ACTION:
Introduce Ordinance No.
hour speed limit from El Camino Real to College Boulevard.
NS-732 to establish upon Cannon Road a prima facie 50 mile per
ITEM EXPLANATION:
Cannon Road from El Camino Real to College Boulevard was opened to traffic on August 9, 2004.
The road is 0.73 miles in length and is generally flat. This portion of Cannon Road has two traffic
lanes along the majority of its length and is fully widened at its intersection with El Camino Real.
Four driveways intersect this segment of Cannon Road. A future project will widen Cannon Road to
its major arterial classification of four lanes divided, including bicycle lanes, sidewalks, curb and
gutter, and street lights. The current 24-hour Average Daily Traffic (ADT) volume on Cannon Road
is 12,400 vehicles.
In the future, the Cannon Road/College Boulevard intersection is expected to be signalized.
Aspeed survey conducted on Cannon Road found the critical speed to be 53 miles per hour.
The critical speed is the speed at which 85 percent of the vehicles are traveling at or below.
Thespeed limit on Cannon Road west of El Camino Real has previously been established at
50 miles per hour.
Sections 22357 and 22358 of the California Vehicle Code authorize local authorities to establish a
prima facie speed limit on the basis of the results of an Engineering and Traffic Survey. The Engineering and Traffic Survey considers such factors as the number of collisions that have
occurred on the road segment, roadway features, adjacent land uses, driveway locations, traffic
volumes, pedestrian volumes, critical speed, horizontal and vertical alignment, stopping sight
distance, and conditions that may not be readily apparent to the driver.
At their meeting on October 4, 2004, the Traffic Safety Commission considered the results of the
Engineering and Traffic Survey to establish a prima facie speed limit upon Cannon Road. The Commission recommended by a 4-0 vote that a 50 mile per hour prima facie speed limit be
established upon Cannon Road from El Camino Real to its intersection with College Boulevard.
The current version of the Engineering and Traffic Survey is on file in the office of the City Traffic
Engineer.
FISCAL IMPACT:
Installing four speed limit signs upon Cannon Road will cost about $500.

ITEM NO. 6B Establish a prima facie speed limit upon Cannon Road from El
Camino Real to College Boulevard.
Mr. Johnson indicated that the Cannon Road item is also to consider a recommendation to establish a
prima facie speed limit. Referring to Exhibit 1, Mr. Johnson explained that Cannon Road is a major
arterial on the Circulation Element from El Camino Real to Cannon Road. It is about 0.73 miles in
length. At this time, Cannon Road is a two-lane divided roadway. When Robertson Ranch develops,
they will be conditioned to build the other two lanes so that in the future, Cannon Road will be a
four-lane divided roadway with bicycle lanes, curbs, gutters, sidewalks, and streetlights. Currently,
it exists as a two-lane divided roadway with a bicycle lane on each side. In general, there are no
curbs, gutters, sidewalks or streetlights except at the 90 degree turn where there are two street lights
and at a driveway serving the nursery there is a street light. Those three streetlights are solar
powered because the electrical lines have not been run for the street lights at this time. The road has
two lanes except at El Camino Real where it widens out to two lanes plus a dual left-turn lane.
Cannon Road west of El Camino Real has been built to the full major arterial standards.
This portion of Cannon Road also opened on August 9, 2004. There have been no collisions
reported. Setting a speed limit now is the type of situation where depending on when we want to
bring forward the results of an Engineering and Traffk Survey, we can wait for more history on the
roadway, whether its collision history, volumes or so on. It is staff's opinion that the volumes have '
stabilized to the point that there is suffkient data for a good valid Engineering and Traffic Survey.
Mr. Johnson said the public is interested in having a posted speed limit on the roadway. The average
daily traffic volume was approximately 12,400 on September 9, 2004. Generally, the road has a
relatively flat vertical alignment and is fairly straight. Cannon Road has a horizontal curve and the
side friction on the roadway is very minimal. There are three driveways that intersect the road, but
otherwise there are no other homes or driveways or other conditions to affect traffic flow.
'
West of El Camino Real on Cannon Road, the speed limit is posted at 50 miles per hour. The
Engineering and Traffic Survey, in the speed survey portion, found a critical speed of 53 miles per
hour. Based upon the critical speed and the results of the Engineering and Traffic Survey, the Traffic
Safety Coordinating Committee recommends that a 50-mile per hour prima facie speed limit be
posted on Cannon Road from El Camino Real to College Boulevard.
October 4,2004 TrafEc Safety Commission Meeting Page 9
Mr. Johnson stated that the same general comments about setting speed limits in accordance with the
Goulet Case as explained in Item 6A are applicable to Item 6B. In conclusion, it is recommended
that a prima facie 50-mile per hour speed limit be posted on this roadway.
DISCUSSION:
Commissioner Bradshaw asked the cost of installing a speed limit sign.
Mr. Johnson said the price is approximately $125 per sign, which includes the telespar post to mount
the sign.
Chair Cress informed the Commission that he has driven portions of both roads himself and found
the speed limit of 45 and 50 miles per hour to be a reasonable speed.
Commissioner Bradshaw asked if it was not posted at 50 miles per hour, did that mean that drivers
could drive at 65 miles per hour.
Mr. Johnson stated there when not posted, the maximum speed limit prevails, and for a four-lane
divided roadway, the maximum speed is 65 miles per hour. A two-lane divided roadway would be
55 miles per hour. That is what state law mandates.
Commissioner Bradshaw asked if the reason we were posting the speed limit was because of public
interest.
Mr. Johnson stated there is public interest. However, it was being posted, which is normally done on
any new road, so that a prima facie speed limit can be established. With a valid Engineering and
Traffic Survey and a speed limit established by ordinance, radar can be used to enforce the prima
facie speed limit.
MOTION:
ACTION: Motion by Commissioner Gardner and duly seconded by Commissioner
Roney, to establish a prima facie 50 mile per hour speed limit upon Cannon
Road from El Camino Real to College Boulevard.
VOTE: 4-0-0
AYES: Cress, Bradshaw, Gardner, Roney
NOES: None
