Subject: Carlsbad Boulevard Pedestrian Improvement Project
Recommended Action
Support staff’s recommendations to implement the proposed traffic calming improvements at
six uncontrolled crosswalks on Carlsbad Boulevard, at the Army/Navy Academy (between
Mountain View Drive and Cypress Avenue), Oak Avenue, Sycamore Avenue, Maple Avenue,
Cherry Avenue and Hemlock Avenue.
Background
On Sept. 24, 2019, staff presented to City Council the proposed actions to address traffic
calming concerns on Carlsbad Boulevard, College Boulevard and Tamarack Avenue. Staff
proposed a project to enhance six uncontrolled crosswalks on Carlsbad Boulevard at
Army/Navy Academy, Oak Avenue, Sycamore Avenue, Maple Avenue, Cherry Avenue and
Hemlock Avenue, which currently have existing Rectangular Rapid Flashing Beacons (RRFB)
systems.
On Jan. 6, 2020, staff presented to the Traffic and Mobility Commission an update on the
proposed Traffic Calming Enhancements on Carlsbad Boulevard, College Boulevard and
Tamarack Avenue.
On Aug. 3, 2020, staff presented to the Traffic and Mobility Commission the conceptual design
for the Carlsbad Boulevard Pedestrian Improvement Project and received feedback on the
proposed traffic calming improvements.
Discussion
Carlsbad Boulevard between Agua Hedionda Lagoon trailhead and State Street is designated as
an identity street in the General Plan Mobility Element. Traffic volumes on Carlsbad Boulevard
can range from 12,000 to 20,000 vehicles per day, depending on location. During the last seven
years, many improvements have been implemented along the corridor including:
• 2012 – Pedestrian scrambles were installed at two locations along Carlsbad Boulevard
(intersections at Carlsbad Village Drive and Grand Avenue)
• 2012-13 – Pedestrian medians and RRFBs were installed at five locations along Carlsbad
Boulevard (Oak Avenue, Sycamore Avenue, Maple Avenue, Cherry Avenue and Hemlock
Avenue)
• 2014 – Carlsbad Boulevard and State Street roundabout, multi-use trail and road diet
were installed
• 2014-15 – Carlsbad Boulevard bridge railing, sidewalk and restriping improvements
were completed
• 2018 – Slurry seal, restriping to accommodate more on-street parking and enhanced
crosswalk signage and legends were installed from Beech Avenue to Mountain View
Drive
On Sept. 22, 2015, City Council approved the General Plan Mobility Element that has the
following recommendation for identity streets: Traffic calming devices, such as curb extensions
(Bulb-outs) or enhanced pedestrian crossings should be considered and evaluated for
implementation. Pursuant to prior City Council direction, staff has evaluated Carlsbad Boulevard
for possible traffic calming measures.
Considering the General Plan Mobility Element recommendations for identity streets, staff
proposes traffic calming improvements at the six uncontrolled crosswalks on Carlsbad
Boulevard. These traffic calming improvements will provide additional safety for all modes of
travel while enhancing mobility for pedestrians and bicyclists on Carlsbad Boulevard. The
proposed improvements are listed below and presented in Exhibit 1.
• Curb extensions (where feasible, at five locations)
• Pedestrian-activated in-pavement flashing lights to augment existing RRFBs
• Continental high-visibility crosswalks
• Green bicycle lane treatments through the intersections in conflict areas
• “LOOK” with arrows pavement markings for pedestrians
• New street lights at crosswalk (at two locations based on photometric analysis)
The proposed green dashed bicycle lane treatments through the intersections indicate the
intended path of people bicycling through the intersection and provide a visual cue alerting
motorist entering the intersection or making turns from Carlsbad Boulevard to the presence of
people bicycling. They provide a clear boundary between the paths of through bicyclists and
either through or crossing motor vehicles in the adjacent travel lane.
The “LOOK” with arrows pavement markings are proposed to remind pedestrians to look for
vehicles prior to crossing the street at an uncontrolled crosswalk location. These markings have
been implemented in other cities in the U.S. and this implementation will be a pilot project in
the City of Carlsbad. Staff will monitor pedestrian behavior after project implementation.
ANSI/IES RP-8-141 recommends a certain roadway illumination levels to be maintained at
crosswalk locations to allow comfortable visibility at night for both drivers and pedestrians.
1 American National Standard Institute/Illuminating Engineering Society, ANSI/IES RP-8-14, American National
Standard for Roadway Lighting, 2014.
Photometric analysis was performed at the six uncontrolled crosswalk locations on Carlsbad
Boulevard based on existing street lights in the vicinity. New street lights are proposed at two
crosswalk locations, Oak Avenue and Maple Avenue, to achieve the illumination levels
recommended.
In November 2020, staff applied for the Highway Safety Improvement Program (HSIP) funds in the
amount of $591,600 to help offset the preliminary design/construction estimated at $657,600.
Results of the HSIP funding applications will be released in early April 2021.
Next Steps
Following the Traffic and Mobility Commission’s review, staff will finalize the project
construction plans, specifications, and cost estimates. There are currently insufficient funds for
construction of the project. Based on the results of the HSIP funding applications, staff will
bring the project to City Council for approval of the construction package and appropriation of
the necessary funds for construction. The construction of the project is estimated to occur by
the end of 2021.
