6A: Loker Avenue East, El Fuerte Street to Palomar Airport Road
- request to revise existing prima facie speed limit.
John Kim presented the staff report explaining that the
Engineering and Traffic Survey on file was approved on
September 12, 2003 with a speed survey dated on May 15, 2003
for Loker Avenue East and has since expired and a new
Engineering and Traffic Survey is required. The current posted
speed is 30 miles per hour. Effective July 1 , 2009, Caltrans issued
a policy directive stating the speed limit shall be established at the
nearest 5 mph increment of the 85th percentile.
Three requirements of setting a realistic prima facia speed limit
are:
« 85th percentile speed (critical speed)
• Collision history
• Conditions that may not be readily apparent to the
driver
Of the three the collision history is the most important to the court.

Loker Avenue East is approximately 0.53 miles in length. The road
follows a curvilinear alignment with many closely-spaced
driveways on either side. The roadway width from curb-to-curb is
52 feet. On-street parallel parking is allowed. Traffic control on
Loker Avenue East is provided by two-way stop control at Loker
Avenue East and El Fuerte Street. 24-hour traffic counts were
obtained on September 2, 2010 and indicated a volume of 5,095
vehicles. Speed surveys were also conducted on October 7, 2010.
There have been no reported traffic collisions on Loker Avenue
East from October 1, 2008 through September 30, 2010.
Concluding, John stated since the California MUTCD requires that
the speed limit be established at the nearest 5 mph increment of
the 85"1 percentile and that no justification for a 5 mph reduction is
given, staff recommends revising the speed limit be established at
40 miles per hour.
Erin Letsch asked if the speed limit was raised to 40 miles per
hour and the collision rate then rose would we consider
lowering the speed limit.
John Kim said yes, we would consider.
Erin Letsch stated if we do not raise the speed limit or update
the Engineering and Traffic Survey this section of roadway is
unenforceable.
The TSCC agreed with staffs recommendation to revise the prima
facie speed limit upon Loker Avenue East from El Fuerte Street to
Palomar Airport Road, from 30 to 40 miles per hour.
Sgt. Paul Reyes arrived at 8:18 a.m.

Loker Avenue West is approximately 0.69 miles in length. The
road follows a relatively curvilinear alignment and has a curb-to-
curb width of 52 feet. It has been improved with curb and gutter,
sidewalk and street lights on both sides. On-street parallel parking
is allowed. 24-hour traffic counts were obtained on September 1,
2010 and indicated a volume of 12,517 vehicles. Speed surveys
were also conducted on September 29, 2010. There have been
two reported traffic collisions, none of which was speed-related.
Concluding, John stated based on the results of the Engineering
and Traffic Survey, staff recommends revising the prima facie
speed limit from 30 to 40 miles per hour.
Erin Letsch also asked if the two reported traffic collisions were
speed related would the collision rate be higher. John Kim stated
no. The collision rate calculation also takes the length of the
segment and number of lanes including the number of traffic
collisions.
Dominic Fieri stated the collision rate of 0.63 for Loker Avenue
West includes all types of traffic collisions. John Kim stated any
type of collision is added to attain the collision rate. If a high
number of traffic collisions were speed related it might be a reason
to justify a 5 mile per hour reduction.
Erin Letsch stated for the same reason I can support the
recommendation.
The TSCC agreed with staffs recommendation to revise the prima
facie speed limit upon Loker Avenue West from Palomar Airport
Road to El Fuerte Street, from 30 to 40 miles per hour.
6C: Aviara Parkway, Poinsettia Lane to El Camino Real - request
to revise existing prima facie speed limit.
John Kim presented the staff report explaining that the
Engineering and Traffic Survey on file was approved on December
27, 2007 with a speed survey dated on October 9, 2007 for this
section of Aviara Parkway. The Engineering and Traffic Survey is
not expired but the Police Department has requested that this
speed zone be re-evaluated due to recent experiences in court.
The current posted speed is 40 miles per hour. Effective July 1,
2009, Caltrans issued a policy directive stating the speed limit
shall be established at the nearest 5 mph increment of the 85th
percentile.
Three requirements of setting a realistic prima facia speed limit
are:
• 85th percentile speed (critical speed)
• Collision history
• Conditions that may not be readily apparent to the
driver
