RECENT (11/01) PEAK HOUR TRAFFIC Figure 1
criteria, the delay at the Prospect/Timberline intersection could not
exceed 122.8 seconds and 119.4 seconds in the respective peak hours. These
values reflect a 2 percent increase in delay at this intersection with the
current geometry.
In the course of conducting these evaluations, it was determined that
full development of Centerpoint Plaza (Buildings A, B, and C) would not
meet the APF criteria. In fact, development of Buildings A and B would
meet the APF criteria in the morning peak hour, but would not meet the APF
criteria in the afternoon peak hour. In light of this, an assignment was
conducted using just Building A. The trip generation for Building A is
provided in Table 2. The total floor area in Building A is 7062 square
feet. As analyzed in this memorandum, the use within Building A was 3000
square feet of medical office, 2000 square feet of business services (print
shop), and 2062 square feet of light industrial (workshop). Trip
Generation, 6th Edition, ITE was used as the reference to calculate the
trip generation for Building A. This trip generation was assigned to the
Prospect/ Timberline intersection using the accepted trip distribution
shown in the cited TIS. The forecasted (2006) peak hour volumes are shown
in Figure 3. Table 3 shows the intersection level of service and delay
using the volumes shown in Figure 3. Calculation forms are provided in
Appendix B. The increase in delay is 0.7 percent and 1.9 percent in the
respective peak hours. Based upon this analysis, it is concluded that
Centerpoint Plaza, Building A will meet the APF criteria at the
Prospect/Timberline intersection.
If, after Building A was approved for development by the City of Fort
Collins, Building B was proposed as a PDP or FDP to the City, an APF
analysis would be required. That analysis, like the Building A analysis,
would need to include the current traffic factored to reflect the analysis
year plus all approved developments which are not built at the time of the
Building B proposal. This would include Building A. From the foregoing
analyses reflected in this memorandum, it is likely that Building B would
meet the APF criteria.

This memorandum addresses the adequate public facilities (APF)
z
T
issues at the Prospect/Timberline intersection for Building A within
aCenterpoint
Plaza. The transportation impact study guidelines
_
indicate that significant impact is defined in Section 4.5.2.A.2 in
z

the "Larimer County Urban Area Street Standards," as follows: "When
w
0
the background traffic conditions (without project traffic) causes
an intersection to fail the minimum acceptable level of service
N
rl-
standards; and when the project traffic causes more than a 2 percent
N
increase in the intersection delay."
The "Centerpoint Plaza Transportation Impact Study," August
2001 demonstrated that all of the key intersections would operate
acceptably with full development of Centerpoint Plaza in the short
range (2006) future. Given this analysis timeframe, it was assumed
that the Prospect/Timberline intersection would be improved beyond
that which exists today. This analysis included a number of
developments which have approved overall development plans, but no
approved preliminary development plans or final development plans.
The assumed improvements at the Prospect/Timberline intersection were
reasonable for this analysis.

The analyses contained in this memorandum use more recent traffic

Since improvements to this intersection are not on a capital

improvement program, City staff requested an APF analysis that

included existing traffic factored to the year 2006 at 1.5 percent

intersection. These projects are: Rigden Farm 6 Filing, Spring

Creek Center, and Midpoint Self Storage. The base (2006) peak hour

ad
traffic at the Prospect/Timberline intersection is shown in Figure

Table 1 shows the intersection level of service and

using the volumes shown in Figure 2. Calculation forms are
QF-
provided in Appendix A. Clearly, this intersection will operate

unacceptably with the existing geometry. In order to meet the APF
