STAFF REPORT
COMMISSION MEETING OF: November 7, 1994 ITEMNO. 6A
LOCATION:
INITIATED BY:
Palomar Airport Road, El Camino Real to Easterly City Limits
City Traffic Engineer
REQUESTED ACTION: Establish a prima facie speed limit of 55 miles per hour on
Palomar Airport Road from El Camino Real to Easterly City
Limits.
BACKGROUND:
Palomar Airport Road is identified on the City's Circulation Element of the General Plan
as a prime arterial. The road width varies from approximately 100' on the west end of
the subject segment to 78' on the east end of the subject segment. Completion of
construction recently has widened and improved the roadway. Two traffic lanes are
provided in each direction except west of Loker A venue East there are three westbound
lanes. Bike lanes are provided from El Camino Real into San Marcos. The median area
is improved with curb and gutter, but absent of landscape and finished surface/concrete.
There are sidewalks only on the north side, west of Loker A venue East and continuing
to El Camino Real.
El Camino Real, El Fuerte Street and Business Park Drive each intersect Palomar Airport
Road and are signalized. The intersections of Business Park Drive and El Camino Real
have dual left-tum lanes to accommodate the heavy traffic. The El Fuerte intersection
has the Bressi Ranch agricultural access road as the southern leg of the intersection.
Existing improvements are shown on Exhibit 2 (attached).
The Cities of Carlsbad, Vista, and San Marcos have just finished a $6 million
improvement project on this roadway extending beyond the limits of the City of Carlsbad.
The previous alignment has been improved, the shoulders graded and widened, and many
of the roadside hazards eliminated. The roadway is built to prime arterial standards in
all locations. Two travel lanes, street lights, sidewalks, and median improvements are the
primary features missing on this arterial. The additional improvements will occur in the
future as parcels develop or as funds become available.
DATA:
Sections 22357 and 22358 of the California Vehicle Code authorizes local authorities to
establish a prima facie speed limit on the basis of the results of an engineering and traffic
survey.

ITEMNO. 6A
The traffic volumes on Palomar Airport Road have increased dramatically over the past
several years. In 1994, 24-hour vehicle counts show a total of 31,725 vehicles using this
roadway. Over the past three years, there have been 57 reported midblock collisions
between Business Park Drive and El Camino Real on the old alignment. Of the 57
collisions, 25 were related to excessive speed, and 19 of the 57 were during the recent
construction activity. The accident rate per million vehicle miles is 0.59 for this three
year period. This is less than half of the expected accident rate for this class of
unimproved roadway.
In October 1994, staff conducted a speed survey on this segment of Palomar Airport Road
(survey attached). Table 1, below, lists the results of this survey.
TABLE 1 -SPEED SURVEY RESULTS
PERCENT CRITICAL
DATE LOCATION 10 MPH PACE IN PACE SPEED
10/18/94 0.4 mi. w/o El Fuerte Street 46 to 56 MPH 76% 56MPH
10/18/94 0. 7 mi. e/o El Fuerte Street 48 to 58 and 49 to 59 MPH 80% 58MPH
The existing 45 MPH prima facie speed limit on Palomar Airport Road between
El Camino Real and the easterly City limits was established several years ago and was
based on a narrow, constricted roadway. Conditions have changed with the new
construction. The roadway, as mentioned above, has been improved and the established
prima facie speed limit needs to be revised.
The segment of Palomar Airport Road from the Price Club entrance to El Camino Real
currently has a prima facie 55 mile per hour speed limit. Six traffic lanes are constructed
from the Price Club entrance to approximately Yarrow Drive. Four traffic lanes are
provided between Yarrow Drive to approximately 500 feet westerly of El Camino Real.
RECOMMENDATION:
The Traffic Safety Coordinating Committee recommends that the prima facie speed limit
on the new segment of Palomar Airport Road from El Camino Real to East City Limits
be established at 55 miles per hour and the portion from the Price Club entrance to El
Camino Real remain at 55 miles per hour.
NECESSARY CITY COUNCIL ACTION:
An ordinance will be required to be adopted by the City Council to establish the prima
facie speed limit as recommended.

F. Remarks: Roadway is used by regional commuters to access the 1-5 corridor. Adjacent industrial and business parks are
rapidly developing. A.M. and P.M. peak hour traffic is heavy.
G. Traffic Engineer's Recommendation (Explanation): This speed zone satisfies the conditions of Section 627 of the California
Vehicle Code and has been prepared and evaluated in accordance with the CAL TRANS Traffic Manual with respect to design
and prevailing speeds, accident history, pedestrian activity, driveway spacing, stopping sight distance, and roadway and traffic
conditions. A speed limit posting of §§ MPH is found to be appropriate and justified.
NOTE: Appropriate speed survey(s) is/are attached hereto and made a part hereof.
