HomeMy WebLinkAboutPRESIDIO APARTMENTS - PDP - 25-09 - SUBMITTAL DOCUMENTS - ROUND 1 - TRAFFIC STUDY' IV. CONCLUSIONS
' This study assessed the impacts of the Presidio Apartments
development on the short range street system in the vicinity of the
proposed development. As a result of this analysis, the following is
' concluded:
The development of the Presidio Apartments is feasible from a
' traffic engineering standpoint. At full development, the Presidio
Apartments will generate approximately 1580 daily trip ends, 121
morning peak hour trip ends, and 150 afternoon peak hour trip
ends.
Current operation at the key intersections is acceptable.
' - In the short range (2014) future, given development of the
Presidio Apartments and an increase in background traffic, the key
intersections will operate acceptably with the recommended
geometry.
Acceptable level of service is achieved for pedestrian, bicycle,
and transit modes based upon the measures in the multi -modal
' transportation guidelines.
The Presidio Apartments will be required to build Precision Drive
' to the north, as well as the adjacent pedestrian facilities along
its frontage.
18
residential uses to the east and north of the site; and 4) the future
commercial/industrial uses within the Harmony Tech Park. In most
cases, sidewalks do not exist within the pedestrian influence area,
except along developed properties. It is assumed that sidewalks will
be completed as properties develop. Appendix E contains a Pedestrian
LOS Worksheet.
Bicycle Level of Service
Based upon Fort Collins bicycle LOS criteria, Fossil Ridge High
School is the only destination area within 1320 feet of the Presidio
Apartments. The bicycle level of service is acceptable.
Transit Level of Service
Currently, Transfort serves this area of Fort Collins with Routes
16 and 17. Routes 16 and 17 run along Harmony Road and Ziegler Road,
0.5 miles to the west of the Presidio Apartments site. These routes
are considered not to be within walking distance of the proposed
Presidio Apartments.

Trip Assignment
Trip assignment is how the generated and distributed trips are
expected to be loaded on the street system. The assigned trips are
the resultant of the trip distribution process. The site generated
trip assignment for the Presidia Apartments is shown in Figure 6. The
site generated traffic was combined with the background traffic to
determine the total forecasted traffic at the key intersections.
Figure 7 shows the short range (2014) total peak hour traffic at the
key intersections.
Signal Warrants
As a matter of policy, traffic signals are not installed
location unless warrants are met according to the Manual on
Traffic Control Devices (MUTCD). None of the stop sign controlled
intersections are expected to meet peak hour signal warrants.
Operation Analysis
at any
Uniform
Operation analyses were performed at the key intersections. The
operation analyses were conducted for the short range analysis,
reflecting a year 2014 condition.
Using the short range (2014) background peak hour traffic volumes,
the key intersections operate as indicated in Table 3. Calculation
forms for these analyses are provided in Appendix C. The key
intersections operate acceptably during the peak hours.
Using the traffic volumes shown in Figure 7, the key intersections
operate in the short range (2014) total condition as indicated in Table
4. Calculation forms for these analyses are provided in Appendix D.
The key intersections operate acceptably during the peak hours.
Geometry
The short range (2014) geometry is shown in Figure 8.
Pedestrian Level of Service
Appendix E shows a map of the area that is within 1320 feet of
' the Presidia Apartments. The Presidia Apartments site is located
within an area termed as a "other," which sets the level of service
threshold at LOS C for all measured factors. There are four
' destination areas within 1320 feet of the proposed Presidia Apartments:
1) Fossil Ridge High School; 2) the residential neighborhood to the
south and southeast of the site; 3) the future commercial and

III. PROPOSED DEVELOPMENT
The Presidio Apartments is proposed to have 240 dwelling units.
Figure 3 shows a site plan of the Presidio Apartments. The site plan
shows access to/from Rock Creek Drive and Precision Drive. The short
range analysis (Year 2014) includes development of the Presidio
Apartments and an appropriate increase in background traffic, due to
normal growth and other potential developments in the area. With this
level of development, Precision Drive would be built between Lady Moon
Drive and Cinquefoil Lane.
Trip Generation
Trip generation is important in considering the impact of a
development such as this upon the existing and proposed street system. A
compilation of trip generation information contained in Trip Generation,
8th Edition, ITE was used to estimate trips that would be generated by
the proposed/expected use at this site. Table 2 shows the expected trip
generation on a daily and peak hour basis.

Trip Distribution
Directional distribution of the generated trips was determined for
the Presidio Apartments. Future year data was obtained from the NFRRTP
and other traffic studies. Figure 4 shows the trip distribution used
for the Presidio Apartments.
Background Traffic Projections
Figure 5 shows the short range (2014) background traffic
projections. Background traffic projections for the short range future
horizon were obtained by reviewing the NFRRTP, reviewing traffic studies
for other developments, and reviewing historic count data for this area
of Fort Collins. Other developments include: Remaining Front Range
Village, MAVD Building, and the Panattoni Buildings. Approximately 70
percent of the Front Range Village is built.

' The traffic data at the Ziegler/Rock Creek intersection was collected
in May 2008. The traffic data at the Lady Moon/Rock Creek and Lady
Moon/Precision intersections was collected in July 2009. It is
important to note that most of the traffic counts were performed when
Fossil Ridge High School was not in session. Historic counts at the
' key intersections and previous transportation impact studies will be
used in developing the future traffic forecasts.
Existing Operation
The key intersections were evaluated using techniques provided in
the 2000 Highway Capacity Manual. Using the recent peak hour traffic
shown in Figure 2, the current peak hour operation is shown in Table
1. Calculation forms are provided in Appendix B. A description of
1 level of service for signalized and unsignalized intersections from
the 2000 Highway Capacity Manual and a table showing the Fort Collins
Motor Vehicle LOS Standards (Intersections) are provided in Appendix
B. The key intersections operate acceptably during both the morning
and afternoon peak hours. This site is in an area termed "other."
Only the Harmony/Lady Moon intersection is in a commercial corridor.
In "other" areas, acceptable operation at unsignalized
' arterial/collector or local intersections is level of service E and at
collector/local intersections is level of service C. Acceptable
operation at signalized intersections during the peak hours in
' commercial corridors and in "other" areas is defined as level of
service D or better, overall. Any leg or movement can operate at
level of service E. At unsignalized intersections, acceptable
I operation is shown as note applicable for arterial/local or
arterial/collector intersections.
' Pedestrian Facilities
There are pedestrian facilities adjacent to developed properties.
' As roads are built to arterial/collector standards, sidewalks will be
included in the street cross sections. Sidewalks will be incorporated
within and adjacent to this development.
Bicycle Facilities
Bicycle lanes exist on Harmony Road, Ziegler Road, Rock Creek
Drive, and Lady Moon Drive. Bike lanes are not required on local or
connector streets.
Transit Facilities
' Currently, Transfort serves this area of Fort Collins with Routes
16 and 17. Routes 16 and 17 run along Harmony Road and Ziegler Road,
' approximately 0.5 miles to the west of the Presidio Apartments site.

II. EXISTING CONDITIONS
The location of the Presidio Apartments is shown in Figure 1. It
is important that a thorough understanding of the existing conditions be
presented.
Land Use
Land uses in the area are primarily commercial, industrial, or
residential. Land adjacent to the site is flat (<2% grade) from a
traffic operations perspective. The center of Fort Collins lies to the
northwest of the proposed Presidio Apartments.
Roads
The primary streets near the Presidio Apartments site are Harmony
Road, Ziegler Road, Lady Moon Drive, and Rock Creek Drive.
tHarmony Road is to the north of the Presidio Apartments site. It
is an east -west street designated as a six -lane arterial street on the
1 Fort Collins Master Street Plan. Currently, it has a four -lane cross.
section with appropriate auxiliary lanes. Some segments are being
expanded to three lanes in each direction in conjunction with the
Front Range Village development. The existing speed limit in this
1 area is 50 mph.
Ziegler Road is classified as a four -lane arterial street, north
of Rock Creek Drive and a two-lane arterial street, south of Rock
Creek Drive on the Fort Collins Master Street Plan. Currently,
Ziegler Road has a two-lane cross section with auxiliary lanes north
' and south of Rock Creek Drive. The Ziegler/Rock Creek intersection
has signal control. The existing speed limit in this area is 40 mph.
' Lady Moon Drive is a north -south street designated as a collector
street south of Harmony Road on the Fort Collins Master Street Plan.
Currently, Lady Moon Drive has a two-lane cross section, with a
continuous two-way left -turn lane, south of Harmony Road. The north
' leg (of Lady Moon Drive) serves the Hewlett-Packard campus. The
Harmony/Lady Moon intersection has signal control.
Rock Creek Drive is an east -west street designated as a collector
street on the Fort Collins Master Street Plan. Currently, Rock Creek
Drive has a two-lane cross section east of Ziegler Road. The Rock
Creek/Lady Moon intersection has all -way stop sign control.
Existing Traffic
Recent peak hour traffic counts at the key intersections are shown
in Figure 2. Raw traffic data is provided in Appendix A. The traffic
' data at the Harmony/Lady Moon intersection was collected in July 2008.

I. INTRODUCTION
This intermediate transportation impact study (TIS) addresses the
capacity, geometric, and control requirements at and near the proposed
Presidio Apartments. The proposed Presidio Apartments site is located
in the northeast quadrant of the Lady Moon/Rock Creek intersection in
Fort Collins, Colorado. The "Harmony Tech Park ODP Master
Transportation Impact Study," (MTIS) December 2007 was submitted and
accepted by the City of Fort Collins. This MTIS addressed the operation
at the key intersections for the long range (2030) future.
During the course of the analysis, numerous contacts were made
with the project developer (Milestone Development Group), the project
engineering consultant (Northern Engineering), and the Fort Collins
Traffic Engineering staff. This study generally conforms to the format
set forth in the Fort Collins transportation impact study guidelines
contained in the "Larimer County Urban Area Street Standards" (LCUASS).
A Base Assumptions Form and related information are provided in Appendix
A. The study involved the following steps:
- Collect physical, traffic, and development
- Perform trip generation, trip distribution,
- Determine peak hour traffic volumes;
- Conduct capacity and operational level of
intersections;
- Analyze signal warrants;
data;
and trip assignment;
service analyses on key
- Conduct level of service evaluation of pedestrian, bicycle, and
transit modes of transportation.
