RECOMMENDATION
1.Establish a speed limit of 35 miles per hour on Armaga Spring Road between Indian
Valley Road and the City's easterly limit west of Highridge Road.
2.ADOPT RESOLUTION NO.2010 ESTABLISHING A SPEED LIMIT FOR
ARMAGA SPRING ROAD BETWEEN INDIAN VALLEY ROAD AND THE
EASTERLY CITY LIMITS.
BACKGROUND
In 1997,City Council approved and passed Resolution No.97-88 Establishing speed limits
on various streets,one of which was Armaga Spring Road.At that time,the residents of
the Stoneridge HOA petitioned the Public Works Department to increase the speed limit
from 25 mph to 35 mph,stating a 35-mph speed limit is more reasonable given the
characteristics of Armaga Spring Road.Subsequent to an Engineering and Traffic Survey
of Armaga Spring Road in 1997,the speed limit of 35mph was established and has now
expired.
On March 11,2010,Willdan Engineers conducted a new Engineering and Traffic Survey
that re-establishes the speed limit to 35 mph.The Traffic Commission,at its March 22,
2010 meeting,voted to support staff's recommendation to maintain the existing speed limit
on Armaga Spring Road at 35 mph.
DISCUSSION
Armaga Spring Road,per the City's General Plan and the Federal Classification System
Map,is classified as a local road and typically the prima facie speed limit on a local road is
25 mph.
Although Armaga Spring Road is classified as a local road,it functions as a collector road.
There are only seven direct residential access points (driveways)and it is a feeder street
that serves several residential streets.Armaga Spring Road is 40 feet wide and
approximately 1800 feet in length.

Page 2
An Engineering and Traffic Survey was conducted on March 11,2010 to establish a new
speed limit for Armaga Spring Road.The results of the survey determined that the speed
limit should be maintained at 35 mph and now establishes a speed limit that is radar-
enforceable.
The Engineering and Traffic Survey for Armaga Spring Road is valid for 10 years.
CONCLUSION
Adopting staff's recommendations will establish a reasonable speed limit along Armaga
Spring Road where radar enforcement can continue.
FISCAL IMPACT
Adopting staffs recommendation will not result in a fiscal impact.By adopting
Resolution 2010-XXX,a 35 mph speed limit along Armaga Spring Road between Indian
Valley Road and the easterly City limits will be enforceable.
No additional funds are required for the installation of new speed limit signs.

Dear Ms.Jules:
As requested,Willdan Engineering has completed an Engineering and Traffic Survey (E&T

above segment.The Engineering and Traffic Survey for the above segment was conducted in
accordance with procedures outlined in the California Manual on Uniform Traffic Control
Devices (CA MUTeD)dated January 2010,and as required by Section 627 of the California
Vehicle Code.
We appreciate the opportunity to serve the City of Rancho Palos Verdes and the assistance and
