STAFF REPORT
COMMISSION MEETING OF: October 2, 1989 ITEM NO . ....QA_
LOCATION: Harwich Drive
INITIATED BY: Franklin A. Weston, 3625 Harwich Drive, Carlsbad, CA 92008
REQUESTED ACTION: Terminate Harwich Drive at Tamarack Avenue by constructing
Harwich Drive as a cul-de-sac street.
BACKGROUND:
DATA:
Mr. Weston has indicated in letters dated May 18, 1989 and September 5., 1989
that a speeding problem exists on Harwich Drive. To eliminate the prob1em he
is requesting tbat Harwich Drive be constructed as a cul-de-sac street at the
intersection of Tamarack Avenue.
Tamarack Avenue is constructed full width from Chatham Road to its terminus at
the intersection of Harwich Drive. The curb to curb width of Tamarack Avenue
is 40 feet and it serves the residential area in the northeast portion of Carlsbad.
This portion of Tamarack Avenue was constructed within the past four years.
Harwich Drive begins at the terminus of Glasgow Drive that is located 600 feet
northerly of Elm Avenue and continues for a total distance of 0.40 miles from Elm
Avenue to the intersection of Tamarack Avenue. It is constructed full width for
a distance of approximately 1.,000 feet westerly and southerly of Tamarack Avenue
and was also constructed witnin the past four years. There are 29 residences that
front directly onto Harwich Drive near Tamarack Avenue.
The portion of Glasgow Drive northerly of Elm Avenue and the southerly portion
of Harwich Drive are both constructed to one-half the ultimate street width.
Future development in the area will construct the remaining one-half of each
street.
Due to the remote location within the City of Carlsbad and no connections to
streets outside of the City of Carlsbad, traffic volumes on Harwich Drive are very
low. A traffic count on Harwich Drive near Tamarack Avenue conducted in June
1989 found 754 vehicles using Harwich Drive in a 24-hour period, 441 vehicles
in an eastbound direction and 313 vehicles in a westbound direction.
Harwich Drive serves as a portion of the circulation system of the housing
development in the Calavera Hills area of Carlsbad. Access to the homes is from
Tamarack Avenue or Harwich Drive. An extensive roadway system will be
constructed to serve this area in the future, as shown on Exhibit 1.
In the interim, the incomplete roadway network provides two points of access to
the subdivision. To av01d long circmtous travel and to proVIde for emergency
services with a minimum of travel time, the City of Carlsbad requires housing
developments to be served from two access roads. This requirement is established
in the City of Carlsbad Engineering Department Policy Number 1 attached.
TRAFFIC SAFE1Y COMMISSION
COMMISSION MEETING OF: October 2, 1989
(Continued)
ITEM NO.~
Constructing Harwich Drive as a cul-de-sac at the Tamarack Avenue intersection
would violate the cul-de-sac policy and establish lon_ger travel routes and longer
response time for emergency vehicles. Both Tamarac!< Avenue and Harwich Dnve
would become a sing1e point access if the construction were implemented.
Tamarack Avenue has an A.D.T. in excess of 2,200 vehicles in the vicimty of Hope
Elementary School near Wilshire Street.
If the cul-de-sac concept were implemented, Tamarack Avenue from Chatham Road
to the Harwich Drive mtersection would be a cul-de-sac 0.70 miles in length and
would serve approximately 205 residences. Harwich Drive from Elm Avenue to the
intersection of Tamarack Avenue would be a cul-de-sac 0.40 miles in length. Items
1 and 2 of the policy are not met by the existing conditions and construction of
a cul-de-sac street would result in a v10lation of the Engineering Department policy
for cul-de-sac streets.
RECOMMENDATION:
The Traffic Safecy Coordinating Committee recommends denial of the request to
construct a cul-de-sac on Harwich Drive at the intersection of Tamarack Avenue.
However1 to remind drivers of the prima fade speed limit in this residence district
on Harwich Drive., staff has issued a work order to install a 25 mile per hour speed
limit sign for eacn direction of travel.
NECESSARY CI1Y COUNCIL ACTION:
No action required at this time.

Dear Mr. Lauber:
Harwich Drive in the Trails area of Calavera Hills is fast
becoming an unsafe throughway due to people driving on it at an
unsafe speed at all hours of the day and night. We fear for the
safety of our children, pedestrians, joggers, and pets. The
homeowners who live in other areas of the Trails drive from Elm
Avenue east on Harwich Drive to Tamarack, then to their homes.
Many of these drivers travel far above the speed limit for a
residential area with tires screeching as they negotiate the
......_,
many turns with an air of abandon. Often, homeowners yell at the
speeding drivers to slow down, but they just drive on unconcerned.
The answer to this problem is not by posting a speed-limit sign,
"slow" sign, or a ''stop" sign. The best solution would be to make
Harwich Drive a cul de sac by placing some sort of appropriately
aesthetic barrier at Harwich Drive and Tamarack. This would not
interfere with the homeowners living in other sections of the Trails
since all streets in that area run off Tamarack. It would, however,
prevent the inevitable death of a child or other person or pet by
carless speeders. We hope to prevent this event by careful planning
and foresight.
We, the undersigned homeowners and residents of Harwich Drive
and Ashby Court request that the City of Carlsbad make Harwich Drive
a cul de sac as outlined above.

Dear Mr. Lauber:
3625 Harwich Drive
Carlsbad, CA 92008
September 5, 1989
In response to our recent correspondance and our telephone
conversation today, the homeowners and residents on Harwich
Drive and Ashby Court renew our request for Harwich Drive to be
made a cul-de-sac at the Tamarack intersection.
Yesterday, there was another accident at Ashby Court and
Harwich Drive where two automobiles crashed and knocked over a
mail box post on the sidewalk. The mailbox could easily have
been a child or pet. Neither automobile was from this neighbor-
hood, and one of the drivers is known by the residents as a
chronic speeder -one who many of the residents have asked to
please slow down in her speed. Her reaction was to tell some
young students that she would report them to their mother that
they were harrassing her.
We request that you follow through on our request for a cul-
de-sac with hearings in the Traffic Coordination Committee and the
Traffic Safty Commission. We feel that this is a very important
request, and that for the good of the neighborhood we must do
something to avoid someone being killed in speeding traffic.
We were very disappointed that our initial request was so
quickly dismissed as unimportant and not possible because of the
overall plan for the proposed neighborhood. Our concern is the
disregard of the drivers who use Harwich Drive as a shortcut speed-
way, and we feel that there is no hope of the situation getting
any better in the future when more houses are built in the area.
Please consider this request as serious, important, and as a
life saver. As citizens of Carlsbad, we request the administration
to follow through on this request.

Thank you for your prompt reply to my letter concerning the
proposed Cul-de-Sac at the Harwich Drive-Tamarack Avenue inter-
section.
Enclosed is a copy of the neighborhood map showing the
desired location of the cul-de-sac, and also the other streets
in the neighborhood showing that a cul-de-sac would not be out-
of-line or unusual in this neighborhood. As you can see, a
cul-de-sac on Harwich Drive would not be inconsistant with the
ones on Hastings Drive, Landsford Way, or Milford Place.
We look forward to the meeting on s@~tGb~eJL. 2 ;, 1989.

Dear Mr . Johnson :
3662 Harwich Drive
Carlsbad, CA 92008
September 26, 1989
We are writing this letter since we will be unable to attend
the October 2, 1989 meeting of the Traffic Safety Commission .
Please do eve r ything you can to help us improve the traffic
situation on Harwich Drive. The average speed seems to be 45-
50 MPH . There are many children and pets on our street, and
it's just a matter of time before one of them is killed. It
is difficult t o back out of one's driveway because the sight
distance to the curve is short and the traffic moves so fast .
Harwich Drive could reasonable be made a cul-de-sac at either
the Northern or Southern end . At the very least , speed bumps
must be instal led. We are very concerned and urge the Traffic
Safety Commiss ion to help correct this dangerous situation as
soon as possib le.
