HomeMy WebLinkAboutSTODDARD PROPERTY - OVERALL DEVELOPMENT PLAN - 42-00 - SUBMITTAL DOCUMENTS - ROUND 1 - TRAFFIC STUDYCONCLUSIONS
Based upon the site investigation, current and projected operating conditions, and the preceding
analysis, the following can be concluded:
• Under existing conditions, each of the key study intersection is operating at acceptable
levels of service.
• For the year 2005 background and total traffic conditions, the study intersection was
found to operate acceptably with the current geometry.
• For the 2020 background and total projected conditions, the study intersection will
operate acceptably with 2 through lanes in each of the north and south directions.
• Additional access points to the development will be pursued at the locations specified in
Figure 7.
SECURITY
The key requirement for achieving a LOS C for security is adequate lighting and line -of sight for
visibility. Both of these will be included in the design of the proposed project.
BICYCLE LEVEL OF SERVICE
Typically, bicycle facilities within the study area are primarily on street bike lanes. On -street
connections to Timberline and the bike lanes on Timberline will provide for good levels of
service to the north and south, which will exceed the minimum LOS C standard for residential
areas.
TRANSIT LEVEL OF SERVICE
There is currently a Transfort transit stop on the Lime Route (14) near the corner of Timberline
and Lincoln with hourly service. Service runs from 6:00 am to 10:00 pm on an hourly schedule,
providing approximately 16 hours of weekday service with a 60-minute headway.
The development is not located in a "mixed use center or commercial corridor" as designated by
the City of Fort Collins Multimodal Transportation Level of Service Manual. Accordingly, LOS
D minimum is met with the above conditions.
PEDESTRIAN LEVELS OF SERVICE
The City of Fort Collins Multi -Modal Transportation Level of Service Manual was used to assess
future pedestrian conditions. Based on requests by the City Traffic Engineer, the project to
proximate residential destinations was analyzed. The key residential elements within the study
area are the adjacent mobile home developments. The westerly edge of the project offers a
number of opportunities for connection to existing residential area, while connections to the east
would require crossing of the ditch.
DIRECTNESS
The goal of LOS C for direct pedestrian access to proximate residential developments is
achieved with the proposed project. The street and pedestrian system is designed to provide
direct connections to the adjacent residential neighborhoods and provide sidewalk connections to
Morroccan Way.
CONTINUITY
The goal of LOS C for continuity is achieved through a sidewalk system along the streets and the
west and east pedestrian connections to the adjacent residential areas, and the industrial area to
the south.
STREET CROSSINGS
The goal of LOS C will be met for the street crossings at International and Timberline, as these
street crossings will be for facilities with three or less lanes in the short run, with appropriate
signing and crosswalks and standard directional curb ramps as the intersection is improved.
VISUAL INTEREST AND AMENITY
The proposed new development, required to meet current development and landscape standards
will achieve or exceed the LOS C threshold.

Long-term operations were assessed for both background traffic growth and total traffic growth
scenarios. Operating conditions are illustrated in Table 5 and Table 6, which represent
conditions with background only, and total traffic, respectively. Long-term improvements such
as the addition of through lanes on Timberline were considered for level of service analysis. As
shown in the following tables, the intersection fails operates at acceptable levels of service for
the critical movements.

IMPACT ANALYSIS
Roadway Improvements
There are no short-term roadway improvements planned for the project area, however, relevant
long-term improvements identified in the City of Fort Collins Master Street Plan include the
widening of Timberline to a 6-lane major arterial.
Traffic Impacts
The key intersection identified by the City Traffic Engineer was analyzed for operating
conditions with the full buildout of the Stoddard project. Total traffic projections reflecting the
background traffic with the addition of the project traffic were developed for both the short-term
and long-term operating conditions. These projections are presented in Figure 10 and Figure 11,
respectively.
Short -Term Operations
The current network should adequately support both the projected background short-term traffic
growth and the project related traffic growth in the study area. The study intersection was
evaluated with and without the project traffic for the short-term study year of 2005. It operates at
acceptable levels of service in the short run. Intersection geometry is generally consistent with
the existing network in the short run. This resulted in the following operating condition seen in
Table 3 and Table 4.

Construction is expected to begin by 2002, with full development expected over 4 years.
Access to the site is planned via Morroccon Way. In addition, a second access point from the
industrial park area to the south or the mobile home park to the west is possible. An emergency
access crossing the ditch to the east may also be provided, connecting to the existing mobile
home park private street as illustrated in Figure 7.
Project Traffic
Site traffic projections were estimated using the 6th Edition of the ITE Trip Generation Manual,
as requested by the City Traffic Engineer. The Single Family Detached ITE category (210) was
used to generate trips for all of the units to provide a conservative estimate of trip generation.
Daily, AM, and PM peak hour trip generation associated with the development is specified in
Table 2. The analysis assumes no transit, ridesharing, bicycle commuting, or telecommuting
mode split adjustments.

Trip Distribution and Assignment
Distribution assumptions for the trips generated by the Stoddard development site are based on
existing land uses, activity and employment center locations, and the existing trip distribution
observed during the peak hour traffic counts. There are no major changes in distribution
anticipated between the short and long-term projections that are associated with the planned
roadway improvements. The distribution is presented in Figure 8 and expected project traffic
assignment is illustrated in Figure 9.

FUTURE BACKGROUND TRAFFIC PROJECTIONS
Short Term Background Traffic
Background traffic was projected using an annual growth rate of 2% on the surrounding roadway
network. Existing traffic volumes were factored using this growth rate to approximate traffic
conditions in 2005. The full development of the Stoddard site was assumed for the short-term
calculations. Short-term background traffic conditions are shown in Figure 5. The study
intersection also continues to operate at acceptable levels of service (LOS B or better).
Long Term Background Traffic
Long-term background traffic projections were arrived at through the application of the 2%
annual growth rate to a 20-year period. Improvements identified in the South College Access
Control Plan were incorporated for analysis of geometry and lane requirements. Changes to the
existing geometrics include the addition of 2 through lanes in the north and south directions on
Timberline per the City of Fort Collins Master Street Plan. Long-term background traffic
conditions are shown in Figure 6.
PROJECT TRAFFIC PROJECTIONS
Development Character
The Stoddard development will add up to 200 multi and single-family homes to the project area.
Surrounding land uses to the east and west are residential, with industrial uses to the south. The
site is bordered on the north by a railroad switching yard.

ANALYSIS OF EXISTING CONDITIONS
Existing Transportation System
The Stoddard development is bordered on the west by an existing mobile home park, on the
north by a railroad switching yard, on the east by another mobile home park, and on the south by
an industrial park. The specific situation of the 50-acre parcel is illustrated in Figure 2.
International Drive is currently a 2-lane facility with a large median, which begins approximately
200 feet west of the International and Timberline intersection. The roadway serves the industrial
development along its frontage and provides the main access to the existing mobile home park
west of the Stoddard property and to the proposed development. Sidewalks are provided
intermittently in the industrial area along International Drive.
Timberline is 4-lane arterial from Mulberry to Donella, a 2-lane arterial with left and right turn
lanes to International Drive, and a 2-lane section with no turn lanes north of the International
intersection. Timberline also has a striped and signed bike lane on both sides from Mulberry to
Vine and beyond. A sidewalk is present on the east side of Timberline between Donella and
International.
Existing Traffic
Weekday morning and afternoon peak hour traffic counts were taken at the study intersection to
establish current intersection conditions. The intersection is currently unsignalized with the lane
geometry identified in Figure 3. Existing traffic conditions are presented in Figure 4.
Existing Level of Service
The study intersection is currently operating at level of service B or better as shown in Table 1.
Relatively low traffic volumes in and out of the project area do not create significant delays at
the study intersection. Level of Service calculations for the unsignalized intersection reflect the
Highway Capacity Manual procedures and are included in the Technical Appendix.

INTRODUCTION
This transportation impact analysis study describes the transportation implications of the
Stroddard Overall Development Plan. The 40-acre site is located generally north of the Fort
Collins Airport, and specifically, just north of the intersection of International Drive and
Morroccan Way. The development will include a mix of single and multifamily homes, adding
up to 200 dwelling units to the area. A map of the project location is presented in Figure 1.
The City of Fort Collins Transportation Impact Study Guidelines (Revised March 27, 1998)
document was used to prepare this report. Accordingly, the analysis includes the following
sections:
• Analysis of Existing Conditions
• Future Background Traffic Projections
• Project Traffic Projections
• Impact Analysis
• Conclusions
• Technical Appendix
Per the TIS Guidelines, an initial scoping meeting with Eric Bracke, the City Traffic Engineer,
was held to establish the scope of this analysis, identify study intersections, and determine base
assumptions for the study. It was agreed that the analysis should incorporate the following
elements:
• Projections for 2005 and 2020
• A 2% future traffic growth rate
• Impact analysis for the intersection of International and Timberline
• Pedestrian analysis for Residential to Residential destinations
