FEASIBILITY OF RESTRIPING RED HILL AVENUE FROM VALENCIA AVENUE TO
EDINGER STREET (EASTBOUND DIRECTION)
RECOMME#DATION:
Restrtpe Red Hill Avenue from Valencia Avenue to Edlnger Street (eastbound
direction) to a three lane cross section.
BACKGROUND:
Pursuant to a request from City Council, an engineering study was initiated for the
subject location. The purpose was to determine if it is feasible to install a
three lane cf'oss section on Red Hill Avenue within the subject limits.
EXISTING CONDITIONS:
Presently,-Red Hill Avenue is classified as a major arterial on the County of
Orange's Master Plan of Arterial Highways. As such, it has a designated
right-of-way (R. O. W.) width of 120 feet and an existing street width varying
between 84 to 102 feet (measured between curb faces) within the defined subject
limits. In addition, there are several median left-turn pockets which provide
access to the collector streets and commercial centers located along Red Hill
Avenue.
Based on a 1986 traffic count, Red Hill Avenue carries an average daily traffic
volume of 30,020 vehicles per day. This volume would relate to Level of Service
"D" (low side) for this type of roadway facility. Level of Service "D" is defined
as traffic volumes equal to approximately 90% of the roadway's theoretical
capacity. Hence, the roadway encompasses a zone of increasing restriction
approaching instability. Delays to approaching vehicles may be substantial during
short peaks within the peak hours of operation.

EVALUATION:
A review was made of the existing stgntng and striping plan for Red Hill Avenue
between the subject 11mits. Based upon this engineering revtew it was concluded
that a three lane cross section can be Installed on Red Hi11 Avenue between
Valencia Avenue and Edtnger Street. The Installation would require the restriplng
of Red Hill Avenue and removing the conflicting pavement markings at Parkway loop
and other driveways. However, the new third lane would terminate at Edlnger Street
by belng designated as a right-turn only lane.
It should be noted that there will be no increase in the carrytng capacity of Red
Htll Avenue with the additional third lane. Furthermore, it should be stated that
there will be some impact to bicyclists slnce they will share the new third lane
([3 feet wtde) with the other motorists using Red Htll Avenue. Red Hill Avenue is
unclassified on the City Master Plan of Bikeways.
In view of the previous discussion, it is staff's recommendation that Red Hill
Avenue be restriped to install a .three lane cross section (eastbound direction)
between Valencia Avenue and Edinger Street.
