BACKGROUND:

Within the past six (6) months, Hillside Drive roadway improvements have been
completed between Sunnyhill Drive and Skyline Drive as part of Carlsbad
Tract 85-18 subdivision. The road has been opened to traffic and Hillside
Drive is essentially a Through Street from Highland Drive to Kelly Drive .
Section 40802 of the California Vehicle Code (CVC) requires that a traffic
and engineering survey be conducted to establish a prima facie speed limit
on a roadway having a width greater than 40 feet and not qualifying as a
local street or road if radar is to be used for speed enforcement. Hillside
Drive has a curb to curb width between 48 and 64 feet and does not qualify
as a local street or road per Section 40802 of the CVC.
Hi 11 side Drive serves as a local co 11 ector street and is 1. 05 mil es in
length between Park Drive and Kelly Drive. The road follows a curvilinear
alignment with roadway grades ranging up to a maximum of 9. 76%. The
easterly portion of Hillside Drive traverses through a residential area
for a distance of 0.55 miles. A school zone is located on the east end of
Hillside Drive at Kelly Drive, the terminus of Hillside Drive.
There were no reported accidents on Hillside Drive during 1987. Eleven
(11) streets intersect Hillside Drive between Park Drive and Kelly Drive
with all intersecting streets controlled by STOP signs.
A speed survey was recently conducted on Hillside Drive at three (3)
locations. Results of the survey are indicated on Table A. The current
24 hour Average Daily Traffic (ADT) volume on Hillside Drive based upon a
recent count is 1,991 vehicles.
