Background
Carlsbad utilizes the Carlsbad Residential Traffic Management Program, or CRTMP, to address
speeding concerns on residential streets. The program was adopted by the City Council in 2001 and
revised in 2011. Staff have collaborated with residents of Park Drive, Black Rail Road, Plum Tree Road
and Carrillo Way, located in various parts of the city as shown in Exhibit 1, to complete the process
outlined in the CRTMP. Additionally, all of these traffic calming plans have met the criteria for
neighborhood support as described in the approved program. Table 1 provides a summary of the
proposed improvements for the four streets.

In response to Commissioner Kohl’s inquiry about lowering the speed limit further to 40 mph,

lowering speed limits. He further added that towards early next year staff should have
recommendations regarding the possibility of lowering speed limits based on AB43.
In response to Commissioner Kohl’s inquiry about performing another traffic study, if the 45-
mph speed limit were implemented, to see if the 85th percentile drops below 40 mph, City
Traffic Engineer Kim explained that engineering studies have shown that critical speeds do not
typically vary over time unless the conditions of the road have changed or traffic volumes
change. He further explained that if everything were to stay the same, there would be no
reason to believe that the roadway speed would change.
