COMMISSION REPORT OF: April 4, 1988 ITEM NO. 6A
LOCATION: La Costa Avenue -Easterly of commercial area east of El Camino
Real easterly to the Calle Madero intersection.
INITIATED BY: Robert and Kimberly Huntoon, 2320 A La Costa Avenue, Carlsbad,
California 92009

REQUESTED ACTION: Install striping on La Costa Avenue to provide for a
continuous two-way left turn lane from a point easterly of
the commercial area located easterly of El Camino Real and
continuing easterly to Calle Madero.
BACKGROUND:
DATA:
This item was discussed at the March 7, 1988 Traffic Safety Commission
meeting with no action taken on the four alternatives under consideration.
The Commission referred this matter back to staff for analysis of one (1)
additional striping configuration proposed by the Traffic Safety Coomission
shown as Exhibit B.
The Traffic Safety Commission asked staff to investigate one (1) additional
alternative striping configuration for La Costa Avenue within the designated
limits under consideration. The Commission alternative would result in
removal of bicycle lanes, but includes a parking lane on the northerly
side of the road and a continuous 2WL TL in the center of the road, in
addition to maintaining two (2) traffic lanes in each direction. This
striping configuration is designated as Alternative No. 5. Other alter-
natives discussed at the Commission meeting of March 7, 1988 are shown on
Exhibit A, with Alternative No. 1 being a Do Nothing alternative (no
change to existing striping).

ITEM NO. 6A
As with most alternatives, there are advantages and disadvantages to each
possible striping configuration. Alternative No. 5 allows for a continuous
two-way left turn lane on La Costa Avenue and provides the parking lane on
the northerly side of the road requested by the residents. However, a
serious disadvantage to this proposal would be the need to eliminate
bicycle lanes on both sides of the roadway. La Costa Avenue is not of
sufficient width to stripe a parking lane, continuous 2WLTL and two (2)
bicycle lanes in addition to four (4) traffic lanes. Advantages and
disadvantages of this alternate are indicated below.
ADVANTAGES -Alternative No. 5
*
*
Provides parking lane on northerly side of La Costa Avenue.
Provides continuous two-way left-turn lane.
DISADVANTAGES -Alternative No. 5
*
*
*
*
*
*
*
Striping does not conform to secondary arterial roadway standards.
Bicycle lanes are eliminated and bicycle safety decreased.
Bicyclists will continue to use La Costa Avenue and travel in
traffic lanes with high speed vehicles.
Striping west of Calle Madero does not properly align with
striping east of Calle Madero (5' offset occurs see Exhibit B).
Parked vehicles on north side obstruct sight distance when
vehicles exit driveway.
Cars with mechanical problems have no refuge area -breakdowns
occur in the Number 2 traffic lane.
No refuge area for Pol ice to provide speed enforcement when
drivers are stopped. Vehicles would stop in Number 2 traffic lane.
As more vehicles increase yearly on arterial roadways and local streets,
other methods of alleviating congestion are necessary. One such alternative
is for the public to use modes of travel other than the single occupant
vehicle. Bicycles are one such mode and have the advantage of not causing
increases in noise and air pollution. Ridership of bicyclists is increasing
as the public looks to ways to increase phys i ca 1 fitness and reduce
congestion and is a form of transportation that should be encouraged.
Provisions must be made to accommodate safe bicycle travel.

COMMISSION REPORT OF: April 4, 1988
(Continued)
ITEM NO. 6A
The Circulation Element of the General Plan for the City of Carlsbad
designates La Costa Avenue as a bicycle route as indicated on Exhibit C.
Removing the road as a designated bicycle route would require a revision
to the General Plan. Bicyclists can be frequently observed using La Costa
Avenue. Planning and engineering staff cannot support the proposa 1 for
elimination of La Costa Avenue as a bike route and the subsequent removal
of painted bicycle lanes.
The Traffic Safety Coordinating Committee recognizes that not providing a
parking lane on the northerly side of La Costa Avenue would inconvenience
a small number of residents. However, overall safety along La Costa
Avenue would be enhanced by providing a continuous two-way left-turn lane
in combination with bicycle lanes on each side of the roadway.
RECOMMENDATION:
The Traffic Safety Coordinating Committee recommends that the previously
recommended Alternative No. 3 be implemented on La Costa Avenue from a
point easterly of the commercial area located easterly of El Camino Real
and continuing easterly to Calle Madero and that a NO PARKING zone be
established on each side of the roadway.
NECESSARY CITY COUNCIL ACTION:
No City Council action is required to change the striping configuration on
La Costa Avenue. The Traffic Safety Coordinating Committee recommends
that any striping changes proposed be discussed at a City Council meeting
before implementation and that the parking restriction be formalized by
City Council adoption of an ordinance designating the NO PARKING zone on
both sides of La Costa Avenue.

Dear Sirs:
)
I would like to make known to you the feelings of the owners
and tenants of the La Costa Be Marbella complex, 2401-2433
La Costa Ave., Carlsbad.
We are very interested in obtaining a turning lane on La Costa
Ave . opposite our entrance. We have 58 families living in our
condo complex, and every day many of us face serious injuries
or loss of life when attempting to make a left turn into our
driveway. There have been numerous "close calls."
It is convenient to have parking on La Costa Ave. And we
do sympathize with our neighbors. It is too bad we can't
have both. But when weighed against the potential for
tragedy I am sure you will agree that something must be done.
La Costa Ave . is becoming a speedway and the squealing of
brakes is a warning we must respect.
~e~/.z4'
