There is no posted speed limit on Yarrow Drive and there a r e
many near misses as a result of the speeding vehicles.
DA TA:
A request for speed limit posting on Yarrow Drive was
discus sed at the Traffic Safety Commission meeting of July 7,
1986. The Traffic Safet y Commission unanimously denied the
speed limit posting request.
Si nce t hat time, staff has received both formal and informal
requests to have a speed limit posted on Yarrow Drive. In
the i ndu strial park where Yarrow Drive is located, Camino
Vida Rob le is posted for 40 mi les per hour. Yarrow Drive
does not qualify as a business district and therefore does
not ha ve a prime facia speed limit of 25 miles per hour.
Yarrow Drive is a one-half mile long industrial street
located within a 62-foot right-of-way and a maximum grade of
4.20% fr om Palomar Airport Road to Camino Vida Roble. One
side s tr eet is located at approximately the middle of Yarrow
Drive. Driveways were built at various locations along the
road to serve the business on Yarrow Drive . Sight distance
is res tr icted for the driveway on the west side of the road
immed iately south of the curve at Corte De La Pina.
Otherwise, sight distance is good.

I TEM N0.6-B
During t he past three (3) years (1984-86), there have been
s i x (6) reported traffic accidents, none of which were
associ ated with excess i ve speed according to police records
(colli sion diagram attached). In August, 1984 a traffi c
count showed an ADT of 3,400 vehicles on the road.
A spee d survey taken on June 5, 1986 found the critical speed
to be 4 6 miles per hour on Yarrow Drive. This indicates that
85% of th e drivers travel at or below that speed and perceive
this t o be a reasonable and prudent speed. Speed limit
signs, when posted, are generally placed at one-hal f mile
interv al s in the City of Carlsbad.
REC OMM END ATIO N:
Based upon the existing roadway, traffic volumes, acciden t
histor y and the results of the speed survey, the Traffic
Safety Coordinating Committee recommends a speed limit of 40
miles pe r hour on Yarrow Drive. In add i tion, the Coordinat-
ing Co mmittee recommends that the property owner at 6211
Yarrow Drive clearly post the two (2) one-way driveways as
"Enter/E xit Only" and "Wrong Way" and notify employees and
vendor s of the one-way status of each driveway .
NECES SARY COU NCIL ACTION:
An ordin ance will be requi r ed for City Council action if the
speed zone is recommended by the Traffic Safety Commission.
