peak -hour conditions.
4. The existing geometry will adequately serve site
traffic as well as the anticipated growth in traf-
fic volumes up to the year 2010.
5, while a significant percentage increase in traffic
volumes on First, Second, and Third Streets is
expected, it is in reality insignificant given the
frequency of vehicles on these streets during peak -
hours.
6. Truck traffic using the site is not considered
excessive or significant since only 3 semi -tractor
trailer combinations per week are expected.
7. Driveway operations and the impacts thereof are
considered insignificant given the low site and
roadway volumes.
8. The existing stop sign controls at the Buckingham
intersections with Lemay and Linden appear capable
of handling traffic for the foreseeable future._

significant, the actual increase in street traffic is numer-
ically insignificant. For example, the number of vehicles
using First Street during the afternoon peak -hour is cur-
rently 35 vehicles or one vehicle approximately every 1.7
minutes. After the cabinet facility is fully operational,
the number of vehicles using First Street during the after-
noon peak -hour is expected to rise to 38 or one every 1.6
minutes. The change in frequency of vehicles on Second and
Third Streets is one vehicle every 2.5 minutes to one every
2.3 minutes and one vehicle every 5.4 minutes to one every
4.6.minutes,. respectively.
CONCLUSIONS
Based upon the previously discussed, noted, and documented
findings, the following can be concluded.
1. Site traffic volumes are considered minor with only
35 + during peak -hour conditions and approximately
170 per day.
2. The proposed project will not produce a noticeable
deterioration in the operating levels -of -service of
the existing roadway system.
' 3. For the most part, intersection levels -of -service
' at the Buckingham intersections with Linden and
Lemay will remain unchanged whether the manufactur-
ing facility is constructed or not. Where drops in
levels -of -service are expected, they will drop to
8
The westbound left -turn movement would operate at LOS "D"
whether or not the facility were constructed. .The westbound
i through movement LOS is expected to drop to LOS "D" in the
year 2010 with the project fully operational; otherwise,
this movement would likely operate at LOS "C". It should be
stated that the westbound through movement does not contain
any site traffic; however, the increase in traffic on Lemay
due to the site is likely the reason for the drop in LOS.
In any event, this reduction in LOS is considered acceptable
under peak -hour conditions given the conservative nature of
the projected traffic volumes.
The eastbound left -turn movement is expected to drop from
LOS "C" to "D" in 1993 or as soon as the cabinet facility is
fully operational. This is not considered significant since
it is expected to drop to LOS "D" at some point between 1993
and 2000 whether or not the cabinet facility is constructed.
As previously stated a visual review of site driveways and
First-, Second-, and Third Streets traffic volumes was
conducted. Site traffic volumes using the proposed drive-
ways are minimal and are considered inconsequential. The
same is true of site traffic expected to use First, Second,
and Third Streets. While, on a percentage basis, the in-
crease in traffic using First, Second, and Third Streets is

IMPACT OF SITE TRAFFIC
Site generated traffic was added to current and future
traffic volumes and analyzed. The argument could be made
that future traffic volume projections already include site
generated traffic; however, in the interest of a conserva-
tive analysis (higher traffic volumes), the additive ap-
proach was taken.
A visual review of traffic volumes was conducted. This
resulted in the realization that traffic volumes on Bucking-
ham, First, Second and Third are minor under any circum-
stance and therefore, further analysis was not considered
necessary. These roadways can best be addressed quantita-
tively rather than undertaking a formal numerical analysis.
The Buckingham intersections with Linden and Lemay carry
higher traffic volumes and, therefore, were fully evaluated
using Highway Capacity Manual techniques. Total traffic
volumes for these intersections, as well as, site driveways
are indicated on Figures 6 and 7 for the current, 2000, and
2010 A.M. and P.M. peak -hour evaluation periods.
ICapacity analyses results at the Buckingham intersections
with Lemay and Linden for the various analysis periods and
conditions are as indicated on the following page.

SITE TRAFFIC DISTRIBUTION
The vast majority of site generated traffic stream will be
comprised of passenger cars. Three rubbish collections and
three semi -tractor and trailer vehicles are anticipated on a
weekly basis. Additionally, 5 - 6 step vans or 20 - 30 foot
truck trips are expected per day. These vehicles will
likely be UPS deliveries and other inter -city delivery
vehicles.
The facility is expected to have 40 manufacturing employees
and 12 office employees. Shifts will typically be from 6:00
A.M. to 2:30 P.M. for manufacturing employees and 8:00 A.M.
to 5:00 P.M. for office staff. For the most part, the site
peak -hours will occur well in advance of the highway peak -
hours.
DISTRIBUTION OF SITE GENERATED TRAFFIC
Given the site's geographic location within the Fort Collins
metropolitan area, the current pattern of the City street
system, and the proposed site access (2 drives along Buck-
ingham), site traffic was assigned to the available roadway
network. The assignment was made on the assumption that 75
percent of the demand would come from areas directly south
and west of the site. The remaining 25 percent would be
from the north and east. Morning and afternoon peak -hour
site generated traffic is shown on Figure 5.

PEAK -HOUR TRAFFIC
Future traffic volumes were estimated for the 2000 and 2010
evaluation years. These volumes are shown on Figures 3 and
4 for the morning and afternoon peak -hour periods. Daily
traffic volumes in 2010 are estimated at 12,200 on Lemay and
1,300 on Buckingham.
For analyses purposes, no geometric roadway improvements are
assumed under design year conditions. Additionally, inter-
section traffic controls are assumed to reflect those cur-
rently in place.
SITE GENERATED TRAFFIC
The Institute of Transportation Engineers' (ITE) publica-
tion, "Trip Generation", was reviewed. Per this 1991 publi-
cation, the proposed project can be expected to generate the
following trip ends.

mated daily traffic on Linden is 1700 vehicles per day. On
Buckingham, some 750 vehicles per day are estimated with the
same geometry and posted speed limit as the north -south
streets. Buckingham is under stop sign control at both the
Lemay and Linden intersections.
First, Second and Third Streets extend from Buckingham to
the south. These local streets have posted speed limits of
25 miles per hour and are two lane roadways. Daily traffic
volume estimates for First, Second and Third Streets are
700, 275, and 120, respectively. Peak -hour turning movement
traffic volumes are shown on Figure 2.
FUTURE ROADWAY CONDITIONS
The City of Fort Collins has provided daily traffic volume
projections for major city roadways for the year 2010. A
review of this information indicated that daily traffic on
Lemay in'the immediate area of the site is expected to grow
at a straight line rate of 3/4 of one percent per year.
Buckingham is not displayed on the City map of 2010 traffic
volumes; however, other collector roadways such as Vine were
reviewed. It appears that a 5 percent per year straight
line growth rate is somewhat typical. Current traffic
volumes on Buckingham, First, Second, Third, and Linden were
escalated 'accordingly.

INTRODUCTION
Phelps-Tointon, Incorporated is planning to construct a
manufacturing facility along the south side of Buckingham
some 400 feet west of Lemay in Fort Collins, Colorado (See
Figure 1). The facility will be used to build and store
cabinets for wholesale trade. The facility, as currently
planned, will be 45,000+ square feet on approximately 6
acres.
The area surrounding the site is mostly vacant land. On the
west side of Lemay, a residential area starts approximately
one -quarter mile west of the project site.
EXISTING ROADWAY CONDITIONS
The facility will be served in the north -south direction by
Linden Street and Lemay Avenue. In the east -west direction,
direct access will be via Buckingham Street. Some minor
developed areas exist to the east across Lemay but these
areas are relatively obscure.
Current daily traffic volume on Lemay in the area of Buck-
ingham is 11,000 vehicles per day. This two-lane facility,
one lane in each travel direction, has a posted speed limit
of 30 miles per hour. No auxiliary lanes exist at the
Lemay-Buckingham intersection. Linden street is also a two-
lane facility having a 30 mile per hour speed limit. Esti-
