FINANCIAL STATEMENT:
Sufficient funds for speed limit signs have been budgeted in the
Street Maintenance Operating Budget
DESCRIPTION: This is the second reading of a proposed ordinance that was
introduced at the April 4th City Council meeting. California Vehicle Code Section 40802 specifies that
engineering and traffic surveys (speed surveys) must be conducted every five years for certain types of
roadways in order to allow speed limit enforcement by use of radar (see Attachment 3). Staff recently
conducted speed surveys on a number of City streets for which the surveys had expired, or for which there
were no pre-existing surveys (See Attachment 4).
The engineering (speed) survey results include the 85th percentile or "critical" speed and other pertinent
criteria such as roadway geometrics and accident history. The "85th percentile speed" (85% of the traffic
travels at this speed or less) is generally considered a "safe speed" unless the other criteria indicate that
the safe speed should be less. For example, it is recommended that residential streets retain their 25 mph
speed limit even if the critical speed is higher. The court considers the survey results when determining

survey recommendations as much as possible.
Therefore, posted speed limits should conform to the
Speed limits are not recommended to change on most of the surveyed streets. Following are the
recommended changes or additions and the reasoning for the recommendation:
Existing
Street Segment Posted Speed Recommended Discussion
Limit Speed Limit
Amador Valley Blvd. from When the speed limit was changed on the
Amador ?lazato Village 35 mph 30 mph westerly portion of Amador Valley Blvd., this
Parkway segment was not surveyed due to construction. It
is now recommended that this segment be
changed to 30 mph for consistency with the rest
of the commercial portion of the street.
Arnold Road from Dublin This roadway was not previously surveyed. The
Blvd. to Gleason Drive 35 mph 40 mph posted speed limit is a holdover from Arnold
(not adopted) Road's previous status as part of Camp Parks and
has not been adopted by the City. Speed survey
results indicate that 40 mph is appropriate for this
segment.
Dougherty Road from The previous survey for Dougherty Road
Park Sierra entrance to 35 mph 40 mph identified the transition point from 35 mph to 40
Monterey (4-600 feet) mph as Monterey Drive, which is the
southernmost entrance into Arroyo Vista. The
traffic signal at the Park Sierra entrance (future
Scarlett Drive extension) now provides a more
appropriate divider between the two speed limits.
Gleason Drive (Arnold Gleason Drive does not have a current posted
Road to Hacienda Drive) None 40 mph speed limit. The speed survey results indicate that
40 mph is appropriate for this arterial. The
remainder of Gleason Drive will be surveyed after
construction is complete.
Hacienda Drive (Dublin 45 mph 35 mph When this segment of Hacienda Drive was
Blvd. toi-580) originally constructed, there were no adjacent
businesses. Since that time, both business and
residential uses have been added, and the 85th
percentile speed has decreased.
Hacienda Drive (Dublin None 35 mph This roadway segment has not been previously
Blvd. to Gleason) surveyed. The survey indicates that 35 mph is
appropriate.
St. Patrick Way None 25 mph The 85th percentile speed indicates that a 25 mph
speed limit is appropriate at this time. It is further
recommended that this street be re-surveyed once
the 1-680 ramps are open.
It is proposed to re-survey Dublin Boulevard east of Hacienda Drive after the construction between the
creek and Tassajara Road has been completed. It is not possible to achieve an accurate survey at this
time. It appears that the critical speed will be lower than the current posted 50 mph speed limit, and Staff
will return to the City Council with a recommendation as soon as the new survey can be taken.
Staffrecommends that the City Council conduct a public hearing, deliberate, waive the reading and adopt
the ordinance establishing speed limits on. Amador Valley Boulevard (Amador Plaza to Village Pkwy.),
Arnold Road, Dougherty Road (Park Sierra to Monterey), Gleason Drive (Arnold to Hacienda), Hacienda
Drive, and St. Patrick Way.
