SHORT RANGE PEAK HOUR TOTAL TRAFFIC Figure 3
right -turn movement operates at level of service E. This
operation is shown on line 1 of Table 2. Provision of an
eastbound right -turn lane will achieve acceptable intersection
operation overall, but some movements will continue to operate
at level of service E. This is shown on line 2 of Table 2.
Provision of the eastbound right -turn lane and adjustments in
the signal phasing will achieve acceptable operation on all
movements during the peak hours. This is shown on line 3 of
Table 2.
It is concluded that the current operation at the
Harmony/Shields intersection is a short duration concern that
can be remedied by providing an eastbound right -turn lane on
Harmony Road. This geometric improvement and adjustments in
the signal phasing will achieve acceptable operation during
the peak hours in the short range future. These improvements
will achieve acceptable operation with the increased traffic
from both Harmony Ridge and the Overlook at Arapahoe Farms.

MEMORANDUM
Fort Collins Traffic Engineer
Planning Department
SUBJECT: Harmony Ridge traffic study update
(File: 9585MEM1)
This memorandum provides an update to the "Harmony Ridge
Site Access Study," September 1995. When Harmony Ridge was
approved by the Fort Collins Planning and Zoning Board, an
issue was raised regarding the operation of the Harmony/
Shields intersection. Analysis of this intersection was not
requested as part of the scope of the site access study.
However, it was agreed that when Harmony Ridge came back for
further approvals, this intersection would be analyzed. L.Per
City staff direction, this memorandum only covers the
operation of this interse�n. Tn a-dTition o ony
edge development, the Over oo at Arapahoe Farms generated
n this analysis.
Figure 1 shows recent peak hour counts at the Harmony/
Shields intersection. Figure 2 shows a schematic of the
approach geometry at this signalized intersection. Table 1
shows the peak hour operation at this intersection using the
peak hour volumes shown in Figure 1.. Calculation forms are
provided in Appendix A. For analysis purposes, a 90 second
cycle was assumed with left -turn phases on all legs.
Acceptable operation can be achieved overall, however, as
noted on the calculation forms, selected movements operate at
levels of service E and F. This is caused primarily by
deficient geometry on the west leg. Observation indicates
that it is a 1120 minute" problem that occurs during the
morning peak hour. This can be remedied by adding an
eastbound right -turn lane and adjusting the signal phasing to
account for this peaking condition within the peak hour.
Figure 3 shows the short range (1998+) peak hour traffic
at the Harmony/Shields intersection. As stated earlier, this
traffic includes traffic from Harmony Ridge and the Overlook
at Arapahoe Farms, as well as, a factored increase in
background traffic (3.5%/year). Table 2 shows the peak hour
operation at this intersection using the volumes shown in
Figure 3. Calculation forms are provided in Appendix B.
Using the existing geometry and phasing in the Table 1
analysis, the morning peak hour operation is unacceptable and
the afternoon peak hour analysis indicates that the westbound
