INITIATED BY:
Camino de los Coches between Calle Timiteo and Maverick Way
Police Department Traffic Division
REQUESTED ACTION: To modify the existing striping on eastbound Camino de los
Coches between Calle Timiteo and Maverick Way, increasing the
number of eastbound through lanes from one to two.
BACKGROUND:
This request was initiated by the Police Department Traffic Division based upon traffic
operations in the vicinity of La Costa Canyon High School. The Police Department has
observed the illegal use of the existing parking/bike lane area of eastbound Camino de los
Coches as a vehicle through lane between Calle Timiteo and Maverick Way during the
morning hours prior to the start of the high school. Based on these observations and
considering the high volume of vehicular traffic entering the La Costa Canyon High
School in the morning, the Police Department has requested that the Engineering
Department Transportation Division investigate the possibility of re-striping this portion
of Camino de los Coches, increasing the number of eastbound through lanes from one to
two.
DATA:
Camino de los Coches is classified as a secondary arterial and has a curb to curb width of
64 feet. This roadway is fully improved with curb/gutter, sidewalks and streetlights on
both sides of the road. There are two travel lanes in each direction from Rancho Santa Fe
Road to Calle Timiteo. East of Calle Timiteo, eastbound Camino de los Coches
transitions from two travel lanes to a single travel lane with a parking lane and bicycle
lane provided. The eastbound parking lane and bicycle lane ends approximately
300' west of Maverick Way in order to accommodate a RIGHT TURN ONLY lane that
serves the high school. In the westbound direction, there is a single travel lane, a parking
lane and a bicycle lane from Maverick Way to approximately 335' east of Calle Timiteo.
From approximately 335' east of Calle Timiteo to Rancho Santa Fe Road, there are two
westbound travel lanes. Exhibit 1 shows the project location.
Traffic control on this portion of Camino de los Coches is provided by traffic signals at
Rancho Santa Fe Road, Calle Timiteo, Calle Acervo, and Maverick Way. The average
daily traffic volume on Camino de los Coches east of Rancho Santa Fe Road is 9,790 as
measured on May 9, 2006. Camino de los Coches serves as the only access to
Stagecoach Park and as the primary access to La Costa Canyon High School. The normal
school hours for La Costa Canyon High School are from 7:45 a.m. to 2:30 p.m.

ITEMNO. 6B
The mid-block collision rate, as measured from September 1, 2005 to August 31, 2007, is
1.68 accidents per million vehicle miles. This compares favorably to the statewide
averages of 2.03 and 2.14 accidents per million vehicle miles for 2 lane roadways and
4 lane divided roadways, respectively.
On a typical school morning, vehicles from the west utilize the parking/bike lane area of
eastbound Camino de los Caches to access La Costa Canyon High School at
Maverick Way. The eastbound queue in the parking/bike lane area of Camino de los
Caches resulting from the right turning vehicles into the school driveway has been
observed to extend to Calle Timiteo and beyond. As typical with most schools, the
majority of the congestion is confined to a relatively short period of time, with the peak
being observed to be approximately 7:15 a.m. to 7:45 a.m. Vehicles from the east use the
westbound left turn lane on Camino de las Caches at the traffic signal to enter the school
grounds. A number of students also access the school from Stagecoach Park.
The majority of these students turn right into Stagecoach Park from westbound Camino
de los Caches and either use the parking lot to make a u-turn and access the school from
the southbound approach of the Stagecoach Park driveway, or they park in the
Stagecoach Park parking lot and walk to school.
The proposed re-striping would encompass approximately 1400 linear feet of roadway
and require the removal of existing striping, new striping, signing modifications and
reconfiguration of the video detection zones on eastbound Camino de los Coches at Calle
Acervo. The proposed re-striping would eliminate on-street parking on the south side of
Camino de los Coches between Calle Timiteo and Maverick Way. Currently, there is
approximately 565 feet of curb available for parking on the south side of Camino de los
Caches. Assuming an average parallel parking space of 25 feet, this is equivalent to
approximately 22 parked vehicles. The north side of Camino de los Coches would be
unaffected by the proposed re-striping and the existing on-street parking would remain.
There is approximately 915 feet of curb available for parking on the north side of Camino
de los Caches between Calle Timiteo and Maverick Way, which can accommodate
approximately 36 parking spaces. Exhibit 2 shows the existing striping on Camino de los
Coches as well as the proposed striping changes.
The on-street parking demand on the subject segment of Camino de los Caches is
relatively light, especially on the south side. The only parking generators in the vicinity,
Stagecoach Park and La Costa Canyon High School, both have off-street parking. Based
on staff observations, the parking area along the south side of Camino de los Caches is
minimally utilized. However, special events at Stagecoach Park do result in on-street
parking to be fully utilized.
The City of Carlsbad has an annual pavement management program that either provides
an asphalt overlay or slurry seal on designated streets. Camino de los Coches is not
scheduled to be overlayed or slurry sealed for approximately four years.

RECOMMENDATION:
ITEMNO. 6B
Based on these findings, the Traffic Safety Coordinationg Committee recommends that
eastbound Camino de los Coches be re-striped between Calle Timiteo and Maverick Way
to increase the number of eastbound travel lanes from one to two. This proposed striping
will result in two eastbound travel lanes on Camino de los Coches, from Rancho Santa Fe
Road to Maverick Way, with the new lane terminating at the existing RIGHT TURN
ONLY lane on eastbound Camino de los Coches at Maverick Way.
NECESSARY CITY COUNCIL ACTION:
City Council approval of establishing the no parking zone on the south side of Camino de
los Coches that will result by re-striping the road will be required by adoption of an
ordinance.
