ted that by the year 2007, Harmony Road was shown to .have a six -lane
oss section. There may be merit in making all the improvements to the
rmony/Ziegler intersection when Harmony Road is widened to the six -lane
oss section.
It is concluded that the key intersections will operate acceptably.
HP HTP, Buildings C and E can be developed and occupied with access at the
Harmony/Technology/HP West Access and Harmony/HP East Access/Cambridge
intersections. A signal will be warranted at the Harmony/Technology/HP
West Access intersection.
eration. Based upon traffic counts at the existing HP facility, the
p generation was factored by 80 percent to account for the use of
ernative modes and the existing transportation demand management
hniques which are currently in use at the existing HP facility.
The directional distribution of the generated trips was determined
by analyzing the current distribution at the HP facility on the north side
of Harmony Road. Since this is a short range (2002) analysis, this is the
most relevant trip distribution available. Figure 5 shows the trip
distribution used for the assignment of site generated traffic for
Buildings C and E. Figure 6 shows the assignment of the site generated
traffic at the key intersections.
Year 2002 background traffic was developed for the key intersections.
The existing traffic counts were adjusted to account for the opening of
Technology Parkway. The Celestica traffic was reassigned to both Ziegler
Road accesses and an access to Technology Parkway. It was assumed that by
the year 2002, at. least 100 dwelling units within proposed developments
(Imago, Willowbrook, Brookfield) to the south and east of HP HTP would be
occupied. However, this development will not have access to Technology
Parkway or to Cambridge Avenue. Therefore, this traffic was assigned to
Harmony Road and Ziegler Road. It was assumed that Harvest Park/Sage Creek
and most of Fossil Lake Village would be developed by the short range
future. Traffic volumes at the Harmony/Ziegler intersection were increased
at the rate of 1.5 percent per year. The Harmony/HP East Access/Cambridge
intersection will be built to allow only right-in/right-out/left-in
movements to the HP East Access and Cambridge Avenue by the year 2002.
Therefore, southbound left turns at the HP East Access were reassigned to
the HP West Access. Traffic volumes to/from the existing HP facility and
Cambridge Avenue were held constant. . Figure 7 shows the short range
background traffic at the key intersections. The site generated traffic
from Buildings C and E was added to the background traffic at the key
intersections and is shown in Figure 8.
As a matter of policy, traffic signals are not at any location unless
warrants are met according to the Manual on Uniform Traffic Control
Devices. Using the traffic forecast shown in Figure 8, a peak hour signal
warrant would be met at the Harmony/Technology/HP West Access intersection.
The peak hour signal warrant analyses are provided in Appendix C.
Using the short range background peak hour traffic (Figure 7), the
key intersections operate as indicate in Table 3. Calculation forms are
provided in Appendix D. The analyses assumed that Harmony Road would
remain as a four -lane facility. The key intersections will operate
acceptably.
Using the short range total peak hour traffic (Figure 8), the key
intersections operate as indicated in Table 4. Calculation forms are
provided in Appendix E. The key intersections will operate acceptably. The
recommended geometry is shown in Figure 9. Even though the conventional
"rule of thumb" indicates that a dual left -turn lane may be needed for the
southbound left -turns at the Harmony/Ziegler intersection, the analysis
indicates that sufficient green time can be provided for Ziegler Road such
that acceptable operation is achieved. It is expected that the 300 left -
turn threshold would only occur during the morning peak hour. If the City
desires to implement dual left -turn lanes on this leg of Ziegler Road, this
can be done. It is noted in the cited traffic study that dual left -turn
lanes were recommended on Ziegler Road in the year 2007 future. It is also

the building and occupancy of two office buildings within the

Hewlett-Packard Harmony Technology Park (HP HTP) located south of

site location is shown in Figure 1. These analyses provide an

Study," November 2000. As discussed with City staff, it specifically

(2002) future. Figure 2 shows the site plan of the two buildings
covered in this development proposal. This proposal is for Buildings
C and E of the HP HTP PDP development proposal which is currently in
the City development review process. It is intended that site access
will be via Technology Parkway, which will be built south of Harmony
Road across from the existing HP West Access, and Cambridge Avenue,
which will be improved and have right-in/right-out/left-in access at
Harmony Road.

intersections. Raw traffic count' data is provided in Appendix A.
