LOCATION: Cassia Road Traffic Calming
INITIATED BY: Eric Osterberg
1710 Fairlead Ave
Carlsbad, CA 92011
STAFF RECOMMENDATION: Information Only
BACKGROUND:
Staff has heard various traffic concerns on Cassia Road between Poinsettia Lane and El
Camino Real and has been working with residents to address those concerns. Cassia
Road serves as a highly traveled connection between Poinsettia Lane and El Camino
Real. The concerns reported to staff included high speeds on Cassia Road as well on the
90 degree turn at Poinsettia Lane, the presence of and excessive noise from oversize
trucks, and the lack of available pedestrian crossings. Staff has implemented various
improvements to address these concerns and is currently implementing a traffic calming
plan for the corridor that utilizes performance-based practical design elements including
cost-effective traffic circles.
DATA:
Cassia Road is classified as a Local/Neighborhood Street according to the Mobility
Element of the Carlsbad General Plan. It serves as the existing connection for eastbound
and westbound traffic traveling between Poinsettia Lane and El Camino Real (See Exhibit
1). According to the Mobility Element, Poinsettia Lane is classified as an Arterial
Connector Street in the proximity of Cassia Road, while El Camino Real is classified as an
Arterial Street. Although Cassia Road is classified as a Local/Neighborhood Street, the
unconstructed section of Poinsettia Lane between Cassia Road and Skimmer
Court/Oriole Court diverts traffic to Cassia Road and as a result, it functions as an
Arterial Connector.
Cassia Road has a curb-to-curb width of 40 feet. The roadway is fully improved with
curb, gutter, sidewalk and street lights on both sides of the road. The roadway is striped
with painted centerline and a bike lane in each direction. Parking is currently prohibited
on both sides of Cassia Road. The speed limit on Cassia Road between EL Camino Real
and Poinsettia Lane is currently posted at 35 miles per hour. The speed zone is based on
a valid Engineering and Traffic Survey conducted in 2013. There are approximately 8,000
vehicles a day that travel on Cassia Road between Poinsettia Lane and El Camino Real.

In response to reported concerns of the 90 degree curve on Poinsettia Lane at Cassia Road,
staff has completed the following improvements:
Reconfiguration of the eastbound left turn on Poinsettia Lane at Cassia
Road
Curve warning signs and speed advisory plates (15 mph) for each
direction of travel
Concrete barriers installed along the outside of the curve
Bike lanes and pedestrian travel routed behind concrete barriers to
provide protection for bicyclists and pedestrians
In response to concerns about vehicle speeding on Cassia Road, staff has completed the
following improvements:
Vehicle lane narrowing via installation of bike lanes in both directions
“35” pavement legends installed to augment posted speed limit signs
Two permanent speed feedback signs installed, one for each direction of
travel
In response to concerns about excessive noise from oversize trucks on Cassia Road, staff has
completed the following improvements:
Installation of truck prohibition signs on Cassia Road, Poinsettia Lane and
El Camino Real
Police Department notification of companies in violation of truck
prohibition
On August 9, 2016, city staff met with residents to discuss on-going concerns about speeding on
Cassia Road. At this meeting, staff committed to preparing a traffic calming plan for Cassia
Road using cost-effective traffic calming measures such as painted traffic circles, similar to what
was implemented on Kelly Drive in the vicinity of Kelly Elementary School.
Key objectives of the proposed traffic calming plan include 1) lowering speeds on the corridor
by introducing traffic calming features at regularly-spaced intervals, 2) not penalizing drivers
traveling at the speed limit, 3) using devices that are self-enforcing, 4) improving the roadway
environment for all users, and 5) enhancing the residential character of the roadway. To meet
these objectives and address resident concerns on the corridor, a traffic calming plan for the
corridor was drafted that included three traffic circles.

STAFF REPORT
COMMISSION MEETING OF: December 5, 2016 ITEM NO. 6C-1
(continued)
Page 3
An important factor for the success of traffic calming projects is the spacing of features at
regular intervals of approximately 500 feet to 700 feet. This spacing encourages consistent, low
speeds on the corridor and discourages drivers from speeding between devices. It also
encourages overall compliance by avoiding a roadway experience that may be irritating to
drivers. Based on the recommended spacing, cost-effective traffic circles were proposed at
Kalmia Circle (West), Kalmia Circle (East), and Nicolia Drive. The reverse curve between Kalmia
Circle (East) and Nicolia Drive functions similarly to a traffic calming “chicane” and this portion
of Cassia Road has been historically where the lowest speeds have been measured. In order to
enhance the traffic calming characteristics of this reverse curve, staff is planning to relocate the
existing speed feedback signs to help reduce speeds even more. (See Exhibit 2)
The traffic circles are performance-based practical elements and will be constructed using
striping and supplemented with ceramic domes. Painted extensions will narrow the roadway
while providing horizontal deflection to reduce speed. Large, reflectorized ceramic domes (8”
diameter with a 3” height) are designed to encourage compliance and accommodate the
turning movements of larger vehicles. Curb ramps will be constructed for pedestrian use and
also to allow bicyclists to and use the sidewalk to bypass each traffic circle. YIELD-control
provided on each approach will improve vehicular access from the side streets and pedestrian
crossings at the intersections.
On October 18, 2016, a public meeting was held at the Dove Library Auditorium. Over 800
notifications were mailed out to residents two weeks in advance of the meeting date and
approximately 50 residents attended the meeting. Staff presented the proposed traffic calming
plan and gave residents an opportunity to provide feedback on the proposed plan, identify
concerns and ask staff questions regarding specific features. Feedback was collected on
comments that were evaluated by staff. Comments were found to be mostly positive and staff
incorporated suggestions if they were feasible and were in line with the project’s traffic calming
objectives.
Staff developed final signing and striping design plans based on the public outreach. Staff is in
the process of implementing the traffic calming plan on Cassia Road. In order to expedite
implementation, components of the work will be conducted by different parties. The majority
of the signing and striping will be performed by our Streets Maintenance crews and other work
will be done by contractors.

LOCATION: Estrella De Mar Road between Poinsettia Lane and approximately 600’
south of Olivine Court
INITIATED BY: Mehdi Sarram
6760 Estrella de Mar Road
Carlsbad, CA 92009
STAFF RECOMMENDATION: Approve an exception to the Carlsbad Residential Traffic
Management Program for Estrella De Mar Road between
Poinsettia Lane and approximately 600’ south of Olivine Court.
BACKGROUND:
Estrella De Mar Road between Poinsettia Lane and Alga Road is a Local/Neighborhood
Street according to the City of Carlsbad Mobility Element. The portion of Estrella De Mar
Road between Poinsettia Lane and approximately 600’ south of Olivine Court features
single family homes fronting the east side of the street. The roadway is 40 feet wide and
is fully improved, featuring curb, gutter, sidewalk and street lights on both sides of the
street. The roadway is unmarked and uncontrolled at its intersections with Cobalt
Drive, Marcasite Place, Peridot Court and Olivine Court. Traffic is controlled by traffic
signals at the intersections of Poinsettia Lane and Estrella De Mar Road and Alga Road
and Estrella De Mar Road. Estrella De Mar Road is curvilinear and features varying
grades approaching 9%.
The portion of Estrella De Mar Road between Poinsettia Lane and 600’ feet south of
Olivine Court meets the residence district definition found in the California Vehicle Code
and is appropriately posted as a 25 mph speed zone. The portion of roadway from 600’
feet south of Olivine Court to Alga Road serves several multi-family developments and
does not meet the California Vehicle Code definition of a residence district, and there is
no speed limit currently posted. The section of Estrella De Mar Road under
consideration as an exception to the program is the segment between Poinsettia Lane
and 600’ south of Olivine Court that meets the definition of a residence district and is
currently posted at 25 mph.
The Carlsbad Residential Traffic Management Plan was designed to address speeding on
residential streets. The program defines a residential street as one that meets the
residence district requirement of the California Vehicle Code and has a curb-to-curb
width of 40 feet or less. The program is a three-phase process, which offer solutions at
increasing levels of cost and complexity. Phase I: Enforcement and Education includes
measures such as the installation of speed limit signs and pavement legends, the
temporary deployment of speed feedback signs, and police enforcement. Phase II:
Traffic Management features performance based practical design using enhanced
signing and striping to help reduce speeds. Due to the increased cost of implementing

these types of features on multiple streets throughout the city, a qualifying criteria has
been established to help prioritize staff resources and budget expenditures. The
program allows Phase II to be considered on streets having a critical speed (the speed at
which 85% of the vehicles surveyed are driving at or below) of 32 miles per hour or
higher. Typically, speed data, including determination of critical speed, is collected
during Phase I.
DATA:
On September 14, 2016, staff met with Mehdi Sarram and other residents to discuss
their concerns of speeding on Estrella De Mar Road between Poinsettia Lane and Alga
Road. Staff outlined the Carlsbad Residential Traffic Management Plan (CRTMP) and
informed the residents that speed studies would be conducted to help quantify the
reported issues and to determine possible solutions.
As part of the Phase I process, it was confirmed that Estrella De Mar Road between
Poinsettia Lane and 600’ south of Olivine Court met the Phase I requirements, including
a curb-to-curb street width of 40’, meeting the legal definition of a residence district,
and staff receiving a request from a resident to consider the street for inclusion in the
CRTMP process.
Speed feedback signs were deployed on Estrella De Mar Road. Locations of the speed
feedback signs were determined during the meeting with Mr. Sarram and other
residents to ensure that the signs were placed where speeds were perceived to be the
highest. Speed feedback signs are commonly deployed for a two-week period. The
display is turned off during the first week of deployment to obtain speed data. The
display is turned on during the second week.
The speed feedback signs were deployed with the display turned off during the week of

The critical speed of 30 mph is less than the qualifying criteria of 32 mph needed to
consider Phase II features on Estrella De Mar Road. However, the Carlsbad Residential
Traffic Management Program allows exceptions to this criteria. It states,
“Any street that does not meet the program eligibility criteria but is nevertheless
considered by city staff to be a candidate for traffic calming will be scheduled for review
and possible approval by the Traffic Safety Commission. If the Commission’s review
leads to the conclusion that the street merits an exception, it will be processed through
the CRTMP as if program eligibility criteria were met. Any street recommended by the
Traffic Safety Commission as not qualifying for an exception may be requested by a
citizen to be reviewed by the City Council for a final determination.”
As Estrella De Mar Road between Poinsettia Lane and 600’ south of Olivine Court meets
the geometric requirements of the CRTMP program, meets the definition of a residence
district, has demonstrated neighborhood support for improvements, and experiences
prevailing speeds that are compatible with traffic calming devices, it is considered by
city staff to be a candidate for traffic calming.
If the exception is approved by the Traffic Safety Commission, staff would proceed with
Phase II on Estrella De Mar Road. Phase II would include a public meeting to formulate
a concept plan and a mail survey to all residents to determine support for the concept
plan. The CRTMP requires a minimum 50% return on mailed surveys and an approval
rate of at least 67% on returned surveys in order to proceed with the plan. The program
requires that the resident-supported plan be approved by City Council prior to
implementation. Since there are other streets currently under Phase II consideration,
staff would incorporate Estrella De Mar Road between Poinsettia Lane and 600’ south of
Olivine Court into the list of active streets. A current list of streets qualified for Phase II
of the program is provided below:

Based on staff resources, funding availability, and other approved streets waiting for
implementation of Phase II, if Estrella De Mar between Poinsettia Lane and 600’ south
of Olivine Court is approved as an exception to the Carlsbad Residential Traffic
Management Program, a public meeting with the neighborhood would likely be held in
the second half of 2017.
Based on the findings contained in this report, and the allowances contained in the
Carlsbad Residential Traffic Management Program, the Traffic Safety Coordinating
Committee supports the exception of Estrella De Mar Road between Poinsettia Lane and
approximately 600’ south of Olivine Court to be eligible for Phase II consideration.
