Consider Approval of the Preliminary Design of the
Intersection of Moorpark Road, Tierra Rejada and Miller
Parkway
The Ventura County Department of Public Works proposes to construct
a realigned Moorpark Road that will join with Tierra Rejada Road and
Miller Parkway at their existing intersection. During the City
Council's meeting of September 19, 2001, a number of design features
for the proposed intersection were discussed. Various measures to
limit north -south travel through the intersection were considered.
The City Council determined that insufficient data had been offered
for its consideration and directed that additional studies of the
intersection be performed and that the City Engineer recommend a
design for the intersection.
DISCUSSION
Willdan, the County's engineering consultant for this project, has
prepared alternative design proposals to address the City's concern
that the realignment of Moorpark Road mitigate the impact of traffic
on Miller Parkway and the traffic entering the existing intersection
of Tierra Rejada Road and Miller Parkway from Moorpark Road. To
address the City's concerns, Willdan has provided three preliminary
designs that prevent traffic to and from Moorpark Road from using
Miller Parkway as a north /south access route. Four potential
designs are described and analyzed in the following sections. The
first three designs incorporate features that prohibit through
north -south traffic between Moorpark Road and Miller Parkway. The
fourth proposal is the original plan proposed by the County. Willdan
completed their submittal of data for the conceptual designs on
January 15, 2002.

1.Proposed Option 1 - Exhibit 1
The features of this option provide a combination of raised
traffic islands, striping, traffic signs and traffic signal
lights that will prohibit through north -south movement of
traffic. The east -west movement and left turn movement of
traffic on Tierra Rejada Road is not impeded. The raised island
in Miller Parkway, on the north side of Tierra Rejada Road is
minimized. This design is functional but can be enhanced to
provide clearer direction to the southbound motorists on Miller
Parkway that their only options are to turn right or left.
2.Proposed Option 2 - Exhibit 2
The features of this option provide the same type of traffic
control facilities of proposed option 1 in a "maxxed out"
configuration. This plan will prohibit through north -south
movement of traffic to a greater degree than any of the other
proposals. The raised island in Miller Parkway, on the north
side of Tierra Rejada Road is maximized. The east -west movement
and left turn movement of traffic on Tierra Rejada Road are
somewhat impeded by the island located in the intersection.
This mid - intersection island is a raised island. The raised
island in the middle of the intersection poses significant
problems. It will result in inefficient operation of the
intersection and poses potential hazard to the motorist with
limited or impaired driving skills. This design, while it will
function, is a classic example of too much traffic control.
3.Proposed Option 3 - Exhibit 3
The features of this option provide the same type of traffic
control facilities of proposed option 1 in a more controlling
configuration. The raised island in Miller Parkway, on the
north side of Tierra Rejada Road is maximized. This plan will
prohibit through north -south movement of traffic to the same
degree as proposed option 1 but has more operational freedom
than proposed option 2. The raised island in the middle of the
intersection is not included in this design. This design should
function well. It offers balanced features that should guide
motorists through the intersection and clearly communicate the
prohibition of north -south through traffic without overwhelming
them with an excess of information.
4.Original Proposal - Exhibit 4
This design represents an enhanced generic intersection design
that includes the addition of right -hand turn lanes for each leg
of the intersection and double left turn lanes for the westbound
to southbound turn movements. These enhancements provide a
better level of intersection capacity. This design was found to

be unacceptable because of the impacts of through north -south
bound traffic to the Intersection of Moorpark Road /Miller
Parkway and Tierra Rejada Road and to the segment of Miller
Parkway north of the intersection.
STAFF RECOMMENDATION
Approve the conceptual design shown on staff report Exhibit 3,
"Proposed Option 3 ".
