Re: Request of San Pacifico Community Assoc, et al, for Stop Signs on Avenida
Encinas at Portage Way/Marlin Lane, Windrose and at Dory Ln. / Meridian Way
Dear Mayor Lewis:
On behalf of the members of the San Pacifico Community Association, the Vistamat @ San
Pacifico Homeowners Association, Santalina Homeowners Association, and the San Pacifico -
Area A Homeowners Association, request is made that the matter of Stop Signs on Avenida
Encinas at Portage WayMarlin Lane, Avenida Encinas at Windrose Circle, and Avenida Encinas
at Dory Lane/Meridian Way be placed on the agenda of the Carlsbad City Council per the attached petitions, which are incorporated by reference (Exhibit # 1).
Avenida Encinas runs through our community, making it necessary for approximately half of the
residents to cross Avenida Encinas in order to use the pool or tennis courts. In the past,
community members have requested a traffic control device to provide safe crossing for
pedestrians crossing Avenida fincinas at the intersection of Portage Way/Marlin Lane. The city’s
response was to install a “PEDESTRIAN” symbol sign in both directions on Avenida Encinas
approaching Portage WayMarlin Lane, as evidenced by the letter dated August 28,2001, a copy
of which is attached. This action, while appreciated, has not reduced the risk of personal injury or
property damage posed by traffic on Avenida Encinas. The risk for our community members
exists whether they are on foot or in a vehicle.
Stopping D~S~BCCS The reasons given by the city’s Transportation Engineer (the Engineer) was that there were “360
feet of stopping sight distance” and 300 feet would allow a motorist traveling at 45 mph to react
and slow or stop. Avenida Encinas is described by the Engineer as an arterial roadway with a
critical speed of 40 mph &e., 85’ percentile speed) (Exhibit # 2). Where and how these
measurements were taken was not set forth in the materials presented in response to our records
request. Presumably, the stopping distances employed assumed dry pavement and a -75 second
reaction time. These, of course, are optimal conditions. Unfortunately, we do not live in an ideal
world. The stopping distance would increase substantially if the surface of the roadway were wet
or slippery (approximately 20%). Reaction times can exceed 2 seconds in elderly people, who are
a significant part of our community. Whether the downgrade of Avenida Encinas compels a 20%
increase in the stopping distance required by Table 201.1 must also be addressed?
Vision Obstruction Impacts Stopping Distance
Further, when the bus stop to the southleast of Portage WayMarlin Lane is occupied by a bus, a
motorist approaching in a northerly direction is unable to see a pedestrian crossing at that
intersection. The attached photosraph show a bus northbound on Avenida Encinas just south of
the intersection at Portage WayMarlin Lane (Exhibit # 3). The second photo simulates the same
bus in the bus stop cut-out (Exhibit # 4). The vision obstruction created for northbound motorists
precludes seeing pedestrians or vehicles approaching to enter Avenida Encinas from Marlin Lane.
The NCTD bus schedules show they run approximately every half hour=
Decision Sight Distance
Further, the CalTrans Traffc Manual, the acknowledged benchmark for highway design, provides
that there should be specified distances for Corner Sight Distance at intersections such as
Windrose, Portage Way and Meridian. This must be determined in light of the critical speed of
40mph. The corner sight distance set forth in Table 405.1A for 40 mph is 440 feet to allow the
driver making a left turn fnwn the crossroad a 7.5 second time window. The Decision Sight
Disrrrnccs set out in Table 405.1B ~tfe: 30 mpb ... 450 feet; 40 mph ... 600 feet. Clearly, even at
the posted speed limit of 35 mph, the 360 fix4 cited by the city’s Transportation Engineer is not
enough distance for drivers to see and react to cars or pedestrians entering Avenida Encinas at
those intersections.
Accident Hkrtory & Tnffic Volume The section on Trstffic Signal Warrants (9-01.2), to which the Ensineer may have alluded in
responding to the earlier request, lists sevd hetors to support the installation of an electrically -
powered traffic signal - such as traffic volume and a history of five or more accidents within a
year. By the data provided in response to our records request, the traffic volume criteria have
been met. The accident history is as follows:
1) 1/7/00 Meridian Way; 2) 8/15/00 Windrose Cir;
3) 10/7/00 Winch.ose Ck 4) 1 1/19/00 Wimbrwe Cir;
5) 12/2/00 Windrose Ciq 6) 5/25/01 W&e Ciq
7) 10/8/02 Meridian Way; 8) a ColIision occurred 4-6 weeks ago at Portage Way, but
does not’appear as reported
ColrclPsioa
While the combination of accident history, traffic volume and sight distance probably warrants a
b.affic signal under the CalTtans manual, installation of stop signs would be an economical
interim step toward reduction of the risk. In combination with a Flashing Beacun (9-05-1 3) and a
Cross Road Siga (W9) there should be a substantial improvement in the safety of our
community.
Wherefore, it is requested that this matter be set on the City Council’s agenda at the earliest
available date unless this renewed request for stop signs on Avenida Encinas is approved without
necessi of such further action. Y

The Board of Directors of the San Pacifico, Community Association, unanimously petitions the City of Carlsbad to erect
a four way stop sign controlled intersection at the comer of Portage way and Avenida Encinas and Avenida Encinas
ad Dory Lo. / Meridian Way. Both of the locations are a tram hazard to pedestrian trafic and vehicular traffic. This
request grows out of a fear for the safety of ouf COmmuRity member approximately ?4 of which live on each side of
Avenida Encinas and must cross this street to use facilities. There has been both reported and unreported accidents at
both intersections.
Portage Way and Avenida Encinas is the location of the San Pacifico Community Recreation Center on the north side of
Avenida Encinas and one of the San Pacifico pedestrian trails on the south side of Avenida Encinas. There are also
vehicle entrances and exits from Portage way onto Avenida Encinas. Pedestrians crossing at this location can't see far
enough east on Avenida Enciaas to determine if crossing the street is de. Vehicular Mi has the same problem
Avenida Encinas and Dory Ln. is the location of the San Pacific0 RV storage lot. The drivers of Large slow moving
vehicle can not see far enough in either direction on Avenida Encinas to determine if a motor vehicle is approaching that
would be a hazard. Pedestrims have the same difficulty.
The San Pacifico community consists of 398 singlefamily detached homes and 56 condominiunis located West of HWY
5 between Poinsettia and Avenida Encinas. San Pacifico is a common interest development as defined in section 135 I of

Dear Sir
The Board of Directors of San Pacifica Area Auuaqhouslypetitionsthe City ofcarlsbadto erect athx way stop sign at the comer of Avenida Encinas and Windrose Cucb h addition to the four way stop signs proposed for the
intersections of Avaida Encmas and Portage Way (Marlin Lane) and Avenida Encb and Dory Lane (Meridian Way) requested by the San Pacific0 Community Association, which we also support. All intersections present a
dangerous conditioa3 because of the prevailing speeds on Avenida Embas and impairad sight distance (vertical and
horizontal) due tothe curves and hills that make up the roadway.
Windrose is the only entrance to Santalha, Rosalina and Areas A-2,3and 4 of our Association. It is also the only exit for Santalina and Rosalina. Left turns onto Win&- are Mow due to the speed of oncoming traffic, which is sight impaired. Rightturns and leftturns onto Encinas are an adventute, oh requiring drag strip acceleration to enter on the traffic breaks. When one side laoks clear, it seems another speeding vehicle appears fmm the other
dw accelerator everytime we want to use Encinas.
There are a number of close calls and unreported accidents in addition to the reported accidents at these
intersections. We are confident that your traffic analysis will show that a significant factor in the cause of these accidents is the lack of effective traffic control. Stop signs will at least give us a fair chance.

AVENIDA ENCINAS PEDESTRIAN CROSSING CONCERNS
me purpose of this letter is to follow Up to your Mer regarding your concerns fat the safety of pedestn'ans who cross Aven'ida Encinas at the MarlinLandPortage Way
intersectioni You are requesthg'that the City install a traffic control devk on Avenida Endnas at this intersection to provlds a safe crossing for pedestrians,
- strsr has completed the traffic studies necessary to dmte the situation and address your concerns. The traffic studies induded ahview of current traffic vofumes,
pedestrian crossing volumes, pedestrian. gap studies and intersection geomtridsight distance evaluation.
Based on the rieSults of the studies, a work order has been Issued to instan' 8 'PEDESTRIAN' symbol sign in both dimns on Avenida Encbras approaching the intersection of f%rtage WayMarlhr-Lane. These-sigris witl giva an advanced warning ta- mtcjffsfs to exped pedestrians to be crossing in thki area
The traffic studies found that during the study periods (it15 a.m. to 12:45 p.m. and
1:45 p.m. to 315 p.m.), there are an average of3 usable gaps for pedestrianre to caws
Avenicta Encinas every minute. Duting this s8m 3 hour time pew, a total of 15 pedestrians were obsewed crossing Avenida Endnas at this intersection without incident. Field measurements of the existing "comer and %bpping' sight distance at this intersection found that the minimum required stopping sight distance of 300 feet (for 40 mph) is being pmvkfed of exceeded. Avenida Encinas, being a secondary
arterial roadway, has a design speed and also a'acr#cal speed" of 40 miles per hour. The *critical speed" (also known as the "85 percentile speed"), is the speed at which
85% of the motorists surveyed we- driving at or Mow. Motorists approaching this intetsedbn on Aven'Kta Enanas CBR see a pedestrian ctossing approximately 360 feet
in advance of the crossing location. This 360 feet of stopping sight distance provides
enough time for a motorist traveling at 45mph to read and elow dawn or stop for a
pedestrian. I

You also mentioned your concerns about motorists exceeding the speed limit on Avenida Encinas. 'You might want to contact .Sgt. Kelly Cain of the Carlsbad
Police Department, Traffic Division at (760) 931-2106, to discuss your concerns and
perhaps request the scheduling of the '%adat trailer' and some enforcement on this
section of Avenida Encinas. The "radar trailer" is an educational device that shows the
posted speed limit and also radars and displays the current speed ofeach appmaching
ve hide.
In closing, the two 'PEDESTRIAN" symbol signs should be installed within the next few
weeks and will give motorists on Avenida Encinas an advanced warning to expect pedestrians to be crossing in the area. Pedestrians need to also be reminded to be alert and cautious when crossing this and any street.
Thank you for your concerns regarding pedestrian safe^ and for your patience while staff completed the traffic studies. If you have any questions, please give me a call at
(760) 602-2734.
