Recommendation
ON
Receive and file this informational report informing the City Council of the
proposed installation of multi -way stop controls at the intersection of Alessandro
Drive at San Luis Rey Avenue.
Background
The intersection of Alessandro Drive at San Luis Rey Avenue is currently controlled by
two-way stop controls with traffic on San Luis Rey Avenue stopping and yielding to
traffic on Alessandro Avenue. In the past few years, staff has received several requests
for the installation of multi -way stop control at the intersection. Staff's previous studies
of the intersection concluded that multi -way stop controls were not warranted.
However, an engineering study conducted in February this year concluded that
installation of multi -way stop controls at the intersection may slightly improve operation
and will increase safety for vehicles, pedestrians and bicyclists.
Findings from the multi -way stop engineering study include:
• Approach traffic volumes on San Luis Rey exceed the approach volumes on
Alessandro but San Luis Rey is the street with stop controls.
• The northbound approach traffic on San Luis Rey is approximately equal to the
total east -west approach volumes on Alessandro. Operation of the intersection
will improve slightly with the multi -way stop controls, but will reduce delay for the
northbound traffic.
• The approach volumes on both streets satisfy the Multi -Way Minimum Volume
Criteria by approximately 95 percent.

• Only 2 crashes have occurred at the intersection in the last 3 years. Both
collisions occurred in 2011.
• Installation of multi -way stop controls increase safety for all roadway users.
Given that the installation of multi -way stop controls will not have an adverse effect on
the operation of the intersection and will improve safety, staff intends to install multi -way
stop controls at Alessandro Drive and San Luis Rey Avenue.
Fiscal Analysis
The fiscal impact will be the costs incurred to modifying the intersection from two-way to
multi -way stop controls which include material and manpower costs. The materials
needed to complete the modification are available at the City's Corp Yard and the work
will be performed by City crews. Nominal costs will be incurred in the future for
maintenance and up -keep.
