VI. RECOMMENDATIONS
This study assessed the transportation impacts of the proposed
Landings Office Park PUD, consisting of 36,640 square feet of
office use. It will be located along the north side of Boardwalk
Drive between. Landings Drive and JFK Parkway. Based upon the
investigations, analyses, and findings discussed earlier, the
following actions are recommended:
1. Restricting the Boardwalk/access driveway to the site to
right-in/right-out movements.
2. Construction of a full -turn access driveway to Landings Drive.
3. Provision of a temporary full movement driveway along JFK
Parkway, which should be restricted to right-in/right-out
movements when the southbound left -turn movement on JFK
Parkway at Boardwalk approaches 150 vehicles per hour.
4. Construction of large radius curb returns at all driveways to
facilitate easy right turns into the site.
5. In the short range future, provide enhancements to discourage
wrong way movements at the Post Office entrance.
_ 6. In the long range future, monitor the Boardwalk/Landings
i intersection for future traffic signal installation.

considered. Accordingly, monitoring traffic volumes at this
location as the area matures is appropriate. Elimination of both
left -turn movements (ingress and egress) at the JFK driveway
appears to be appropriate with the long term traffic projections
at the JFK/Boardwalk intersection. This is due to the stacking
requirements for the left -turn movement from JFK to Boardwalk.
When and if the left -turn volume approaches 150 vehicles per hour,
restricting the driveway .to right-in/right-out movements is
appropriate. Monitoring traffic at this location is also
Iappropriate.

V. TRANSPORTATION IMPACTS
Key intersections were analyzed using the unsignalized and
signalized analysis techniques as published in the "Highway
Capacity Manual," Special Report 209, TRB, 1985.
' Table 2 shows the level of service analysis using the 1995
morning and afternoon peak hour traffic. Calculation forms are
provided in Appendix B. Key intersections generally operate
acceptably during both peak hours. Acceptable operation is defined
as level of service D or better. The delay associated with level
of service E operation at the Boardwalk/Landings intersection
' during the afternoon peak hour is common and is generally accepted
at stop sign controlled intersections on busy streets in urban
areas.
In the short range future, it is expected that a signal would
be warranted and installed at the Boardwalk/JFK intersection. This
warrant is based upon City traffic projections and the extension
'
of JFK to Horsetooth Road. Table 3
shows the short range peak hour
operation at the key intersections.
Calculation forms are
provided
in Appendix C. With signalization,
the intersection is
expected
to operate at acceptable levels of
hours. Acceptable operation can
service (LOS) during
also be anticipated
the peak
at the
Boardwalk/Landings intersection with
stop sign control.
During
the afternoon peak hour, level of
service E operation will
occur
for southbound left turns at this
intersection. This is
similar
to the current operation. It should be noted that this analysis
assumes that more appropriate signing and striping or site
circulation changes will be installed at the Post Office to clarify
and support one way operation. All site driveways are also
expected to operate acceptably with full -turn movement operation
I , except at the Boardwalk/access driveway intersection, which should
be limited to right-in/right-out movements.
The need for auxiliary lanes at each site driveway was also
' investigated. It was determined that auxiliary lanes are not
required. However, large radius curb returns should be installed
to expedite right -turn movements into the site at all locations.
Table 4 shows the level of service at key intersections in the
long range future. Calculation forms are provided in Appendix D.
All driveways and intersections are expected to operate acceptably
with the geometry and controls described under the short term
evaluation presented above with two exceptions. The exceptions are
the southbound left -turn movement at the Landings/Boardwalk
intersection, which is expected to drop to LOS F, and both left -
turn movements at the JFK/Driveway intersection. At the Landings/
Boardwalk intersection, the anticipated southbound left -turn volume
may or may not be realized, depending upon the actual shift of
traffic to JFK Parkway and traffic growth rates. If and when the
projected traffic volume is realized, signalization should be

A shared access with the property to the north will accommodate
the displaced left -turn movements.
IV. TRAFFIC VOLUMES AND TRIP ASSIGNMENT
Current morning.and afternoon peak hour traffic was obtained
on February 21, 1995, at the JFK Parkway and Landings Drive
intersections with Boardwalk Drive. Raw count data is provided in
Appendix A. The traffic count is shown in Figure 4. Actual counts
were rounded to the nearest 5 vehicles per hour. It should be
noted that 15-30 vehicles were counted exiting the Post Office site
at the Landings/Boardwalk intersection during each peak hour. It
appears that this access was intended to be a one way entrance
(southbound only) into the Post Office. Accordingly, these
movements should be better controlled.
Trip Assignment
The trip assignment is the product of the trip generation and
trip distribution process. Site access points, as indicated on the
site plan, were reviewed. This review resulted in the
determination that left -turn in and left -turn out movements at the
Boardwalk Drive/site access cannot be reasonably accommodated,
given the proximity of. the JFK Parkway intersection and current
traffic volumes. Intersection spacing is also an issue at the JFK
Parkway access to the site. However, current traffic volumes are
low on JFK and, therefore, turn restrictions are not critical at
this time. A full movement access on Landings Drive appears
acceptable.
Figure 5 shows the short range (1997) trip assignment with
Landings Office Park fully constructed. The site generated traffic
was combined with the background traffic to determine the total
traffic at the key intersections. Background traffic was estimated
for both short and long range conditions, assuming the extension
of JFK Parkway to Horsetooth Road. This extension is expected to.
cause a significant shift in traffic from Landings Drive to JFK
Parkway, and a major increase in the importance of JFK Parkway in
the City street system. .The extension is anticipated in late 1995
or 1996, as well as the installation of a traffic signal at the
JFK/Boardwalk intersection.
Long range peak hour traffic volumes are shown in Figure 6.
In the long term (2015), JFK Parkway traffic volumes are expected
to increase significantly. It is expected that JFK Parkway will
have to serve some 10,000-15,000 vehicles per day and provide
access to significant office and retail developments. JFK Parkway
will also serve as a recirculation road in this area, similar to
the function of Mason Street, west of College Avenue. The
completion of JFK Parkway between Harmony Road and Horsetooth Road
is expected to provide some traffic relief for Landings Drive and
Boardwalk Drive. The Landings/Boardwalk intersection is assumed
to remain with stop sign control on Landings Drive. Figure 6
reflects the earlier conclusion that the site access driveway to

III. TRIP DISTRIBUTION
The overall directional distribution of the site generated
traffic was estimated based upon existing travel patterns in the
area of the site, the site's location within the City of Fort
Collins, and the street system serving the immediate area. Trip
distributions were developed and rounded to the nearest 5 percent
as shown in Figure 3.

II. TRIP GENERATION AND DESIGN HOURLY VOLUMES
Trip generation was estimated using Tr p Generation, 5th
Edition, ITE. Table 1 shows the daily and peak hour trip
generation for Landings Office Park. A trip is defined as a one
way vehicle movement from origin to destination. The origin or
destination of a,generated trip would be within the office park
area. The area of each building includes 1000 square feet of
office use in the basement, with the balance of basement space used
for storage/archive purposes.

II. INTRODUCTION
This traffic study for Landings Office Park PUD addresses the
capacity, roadway geometry, and traffic control requirements
associated with a proposed office development. The project will
be situated between JFK Parkway and Landings Drive along the north
side of Boardwalk Drive in Fort Collins, Colorado. The site
location is shown in Figure 1.
Existing and Proposed Site Uses
The land for this development currently has a few structures.
The applicant is proposing to construct eight office buildings
having a total of 36,640 square feet of office space, plus some
support archive storage space, which is considered insignificant
from a traffic engineering standpoint. The entire project is
expected to be fully developed by the end of 1997. Figure 2 shows
a site plan of the Landings Office Park.
Site Access
Access is proposed via driveways to the adjacent street
system: one driveway to JFK Parkway, one to Landings Drive, and
one to Boardwalk Drive. All driveways are shown as full movement
access points on the site plan. This will be further evaluated in
this traffic study. A future connection to the property to the
north is also contemplated when that property is developed. Stop
sign control is anticipated at all driveway intersections with the
city street system.
Ia Existing Land Uses
Land uses in the vicinity of Landings Office Park are
predominantly office, retail, or vacant. There is vacant land
immediately to the east and north of the site. A major Post Office
facility currently occupies the area east of JFK Parkway and south
of the Landings Office Park site. Major retail stores (Toys R Us
and Shopko) are located west and northwest of the site, between JFK
Parkway and College Avenue.
