SUBJECT
Resolution 2015-043 Determining That a Single-Lane, Modern Roundabout is the Preferred Alternative for the
Intersection of Lincoln Avenue and the North-South Extension of “International Boulevard.”
EXECUTIVE SUMMARY
The purpose of this item is to approve a single-lane, modern roundabout intersection at Lincoln Avenue and
the north-south extension of International Boulevard. The adopted Master Street Plan anticipates a new
arterial-arterial intersection between Lincoln Avenue east of Lemay Avenue and a north-south extension of
‘International Boulevard’. In accordance with Resolution 2001-120, an Alternatives Analysis was completed for
this intersection. The conclusions of the Alternatives Analysis show that a single-lane, modern roundabout is
the preferred alternative for this intersection. This project is not a part of, or within, the boundaries of the
recently approved Lincoln Corridor Improvement Project.
STAFF RECOMMENDATION
Staff recommends adoption of the Resolution.
BACKGROUND / DISCUSSION
The proposal of a development plan known as Capstone Cottages in the northeast vicinity of Lincoln Avenue
and Lemay Avenue has prompted City staff to review how Lincoln Avenue will connect to a new north-south
leg of “International Boulevard” (Vicinity Map, Attachment 2), which would be renamed by City Council in a
future resolution. The City’s Master Street Plan (Attachment 3) graphically depicts that east of Lemay
Avenue, Lincoln Avenue would curve to the northeast to become a new north-south street that would connect
to an extension of International Boulevard, with existing Lincoln Avenue tying in at a T-intersection east of this
sweeping curve. This new arterial-arterial intersection was evaluated by Wilson & Company, Inc. as a
signalized intersection with turn lanes compared to a single-lane modern roundabout. This Alternatives
Analysis report (Attachment 4) compares the two intersection improvement options in terms of safety, right-of-
way requirements, cost, constructability, multi-modal enhancements and operations.
Conceptual Level exhibits for both improvement options are shown on pages 15 and 16 of the Alternatives
Analysis Report. The roundabout outperformed the signalized intersection in the categories of: safety, right-
of-way impacts, costs, access management and operational efficiency. The categories of environmental
impacts and multi-modal enhancements were neutral. The City’s Engineering staff is recommending a single-
lane roundabout as the preferred option.
Note that the decision regarding traffic control at this intersection is independent of the proposed development.
This traffic control recommendation will stand regardless of whether the development proposal moves forward
and is approved or not.
Agenda Item 10
Item # 10 Page 2
CITY FINANCIAL IMPACTS
Preliminary cost estimates in the Alternatives Analysis report demonstrate that it will cost approximately
$723,000 less to construct the roundabout than the signalized intersection, and that right-of-way costs for the
roundabout are approximately $239,000 less than for the signalized intersection. If the Capstone Cottages
development plan moves forward and is approved, the construction of the roundabout would be the
responsibility of the developer with reimbursement of the oversized portion through Street Oversizing. Should
this development plan, for whatever reason, not move forward, City staff would want to ensure that the
roundabout option remains the required intersection control to be built, whether by a future development or a
City capital project. Additionally, the roundabout provides short and long term economic benefits by easing
traffic congestion, resulting in reduced fuel consumption and multi-modal safety improvements with fewer and
less severe accidents.
BOARD / COMMISSION RECOMMENDATION
At its February 18, 2015 meeting, the Transportation Board unanimously recommended approval for a
roundabout at this intersection (Attachment 6).
PUBLIC OUTREACH
Neighborhood meetings for the Capstone Cottages development plan were conducted in February, July, and
December 2014. With the proposal of a roundabout as part of the development plan, questions and comments
were made regarding the roundabout, as well as a signalized intersection. Comparisons between a roundabout
and a signalized intersection on the topics of costs, accidents rates, and operational design were discussed.
There was general support for the roundabout provided that it is designed to address the traffic volumes and
handle large vehicles and trucks.

1.0 Introduction
Growth is expected to occur in the area of the Lemay/Lincoln intersection in Fort Collins, Colorado. As
this area develops International Boulevard will be constructed and connect with Lincoln Avenue east of
Lemay Avenue. Several ultimate alignment concepts for these roads have been developed. The
intersection control needs to be determined for the Lincoln Avenue/International Boulevard therefore
the purpose of this report is to compare intersection options for this intersection in terms of operations,
safety, intersection impacts and right-of-way requirements, environmental, cost, constructability, and
multi-modal enhancements
The two options that are being considered for the Lincoln Avenue/International Boulevard intersection:
Option 1 a sweeping curve alignment for Lincoln Avenue/International Boulevard, as shown in the City
of Fort Collins Master Street Plan, with a signalized Lincoln Avenue/International Boulevard “Tee”
intersection; Option 2 a modern roundabout intersection along the current alignment of Lincoln Avenue.
Figure 1 shows the intersection location area.

1.1 Existing conditions
Lincoln Avenue west of Lemay Avenue is an east-west street classified as a two-lane arterial according to
the Fort Collins Master Street plan. Currently, Lincoln Avenue at the Buffalo Run apartment
access/proposed International Blvd. intersection has a three-lane cross section, one through lane in
each direction and a continuous left turn lane. The posted speed limit in the vicinity of the identified
intersection is 35 mph. The existing Buffalo Run access/Lincoln intersection is presently STOP sign
controlled with STOP control for the northbound approach.
Lincoln Avenue carries approximately 8,300 vehicles per day (vpd). There is a detached sidewalk located
along the south side and bicycle lanes along both sides of Lincoln Avenue east of Lemay Avenue.
Transfort bus route 14 operates in both directions along Lincoln Avenue in the area.
1.2 Intersection Options
As noted previously, two intersection options were evaluated for the Lincoln Avenue/International
Boulevard intersection 1) a sweeping curve alignment for Lincoln Avenue/International Boulevard, as
shown in the City of Fort Collins Master Street Plan, with a signalized Lincoln Avenue/International
Boulevard “Tee” intersection, 2) a modern roundabout intersection along the current alignment of
Lincoln Avenue. Conceptual layouts of each of these options were prepared and are included in
Appendix A.

2.0 Intersection Operations
Year 2035 AM and PM peak hour traffic operation analyses were performed for each of the intersection
concepts.
2.1 Signalized Intersection Analysis
Utilizing the traffic volumes noted above, a signal warrant analysis was conducted for the study
intersection. Warrant-3 Peak Hour from the Manual on Uniform Traffic Control Devices (MUTCD), 2009
was applied at the intersection since these peak hour forecasts were readily available. Based on the
evaluation year 2035 traffic volumes at the study intersection would be at and/or approaching the need
to signalize the study intersection. Therefore a signalized intersection analysis of the intersection was
conducted. The signalized intersection operations analyses were performed using Synchro 8 software,
which uses the methodologies outlined in the 2010 Highway Capacity Manual (HCM).
The Level of Service (LOS) for intersections is defined in terms of delay, which is a measure of driver
discomfort, frustration, fuel consumption, and loss of travel time. Specifically, LOS criteria are stated in
terms of the average control delay per vehicle for the peak 15-minute period within the hour state in
terms of the average control delay per vehicle for the 15-minute period within the hour analyzed. The
average control delay includes initial deceleration delay, queue move-up time, and final acceleration
time in addition to the stop delay.
Table 1 summarizes the HCM criteria and ratings for signalized intersection LOS. Table 2 summarizes the
2035 AM and PM peak hour signalized intersection traffic operations.
Table 1: HCM LOS Criteria for Intersections
LOS
Control Delay
(sec/veh) Description
A <10
Operations with very low delay and most vehicles do not
stop.
B >10 and <20
Operations with good progression but with some
restricted movements.
C >20 and <35
Operations where a significant number of vehicles are
stopping with some backup and light congestion.
D >35 and <55
Operations where congestion is noticeable, longer
delays occur, and many vehicles stop. The proportion of
vehicles not stopping declines.
E >55 and <80
Operations where there is significant delay, extensive
queuing, and poor progression.
F >80
Operations that are unacceptable to most drivers, when
the arrival rates exceed the capacity of the intersection.

2.2 Roundabout Analysis
Operational analysis for the roundabout alternative was performed using Roundabout Delay (RODEL).
RODEL is nationally recognized standard software for empirical geometric design that interactively
generates and assesses roundabout geometry and operations. The year 2035 AM and PM base peak
hour traffic volumes were input into RODEL along with the roundabout geometrics at the intersection.
Table 2 tabulates the roundabout operational analyses.

3.0 Safety
A well-designed roundabout promotes speed consistency and reduces vehicle speeds upon entry and
achieves consistency in the relative speeds between conflicting traffic streams by requiring vehicles to
negotiate the roundabout along a curved path compared other intersection configurations. The risk of
being involved in a severe collision is lower at roundabouts than at other forms of intersections,
including signalized intersections, due to the slower vehicle speeds. In addition the number of vehicle-
vehicle conflict points for roundabouts decreases from 32 to 8 for four-leg intersections, a reduction of
75%. Likewise, the number of conflict points for pedestrians-vehicles is lower at roundabouts than at
other intersections.
4.0 Right of Way
The conceptual layouts were used to determine the intersection impact area, illustrated in Figures 2 and
3, and right-of-way requirements, illustrated in Figures 4 and 5, for each of the intersection concepts.
The right-of-way for the intersection area was obtained from the City of Fort Collins GIS. The alignment
of Lincoln Avenue and International Boulevard are not consistent between the options therefore for
comparative purposes the future east-west road (Duff Drive), located to the north, was used as the
northern ROW limits.
Option 1 will require approximately 110,220 SF of additional right-of-way, while Option 2 will require
approximately 80,370 SF of additional right-of-way.

5.0 Environmental
From an environmental impact perspective the options are fairly similar and summarized below.
x Wetlands: The roundabout option will have less impact to the ditch wetlands north of Lincoln
Avenue compared to the signal option. These are not expected to be jurisdictional but a review
by a certified biologist is required. Mitigation for wetlands impacts, if required, can be
developed within future detention ponds.
x Traffic Noise: Both options will generate similar noise profiles which may impact the outdoor
use areas, e.g. balconies/porches, of Buffalo Run apartments. The roundabout would provide a
consistent travel speed, without vehicles starting/stopping that would be associated with a
signalized intersection which would provide a minor advantage over the signalized intersection
option. The signalized intersection being slightly farther away from the apartments provides a
minor noise advantage over the roundabout option.
x Trees/Vegetation: Both of these alternatives have the potential for impacts to the existing urban
forest on the north and possibly south sides of Lincoln Avenue. The north side impacts are
primarily to trees which are considered nuisance/invasive species. These trees would be
replaced with trees approved by the City of Ft Collins forester. Impacts to the older growth trees
on the south side of Lincoln Avenue should be avoided. The signalized intersection does provide
a greater buffer to these trees and minimizes the potential to impact their roots.
x Air Quality: Roundabouts are generally better for air quality because they eliminate stopping
and idling at the intersection. A detailed analysis has not been provided.

7.0 Multi-Modal
As noted previously there is a detached sidewalk located along the south side and bicycle lanes along
both sides of Lincoln Avenue east of Lemay Avenue. The signalized option would add sidewalks; curb
ramps, and crosswalks at all four legs of the study intersection. On street bike lanes would be provided
on International Boulevard.
The roundabout would also provide sidewalks and curb ramps on all legs of the roundabout. A
roundabout is generally viewed as safe or safer for pedestrians when compared to a signalized
intersection, based on studies of other single lane roundabouts in the United States. Single lane
roundabouts also have a good safety record for bicyclists. The proposed concept design provides a
widened path for cyclists who prefer to not travel through the circulating roadway. More experience
riders may choose to stay in the street and “claim the lane” while traveling through the roundabout. The
performance of a roundabout for visually impaired pedestrians is not as good as a traditional
intersection. This is because visually impaired pedestrians have greater difficulty in determining the
movements of approaching traffic in the roundabout.
8.0 Summary and Conclusion
Option 2 (Roundabout Intersection) provides better intersection traffic operations and safety for both
pedestrians and vehicles than Option 1 (Signalized Intersection). From the environmental overview
evaluation the Roundabout Intersection Option would be less impactful compared to the Signalized
Intersection Option primarily from a noise and air quality perspective since there will be less
stopping/starting and idling at the intersection. The Signalized Intersection Option would have fewer
impacts to trees and minimize noise impacts to the residents in the Buffalo Run apartments. The overall
construction costs, including ROW, would be less for the Roundabout option. The Signalized option
would require the existing Buffalo Run full movement access onto Lincoln Avenue to be reconstructed
and potential restricted to right in/right out movements only.

*The Fort Collins SAT was developed by modifying the Triple Bottom Line (TBL) Analysis Tool developed by Eugene, Oregon, July 2009. 1
City of Fort Collins SUSTAINABILITY ASSESSMENT TOOL (SAT)
(November 2014)
Creating a sustainable community
Plan Fort Collins is an expression of the community’s resolve to act sustainably: to systemically, creatively, and thoughtfully utilize environmental,
human, and economic resources to meet our present needs and those of future generations without compromising the ecosystems upon which we
depend.
How to use the tool
The Sustainability Assessment Tool (SAT) is designed to inform a deeper understanding of how policy and program choices affect the social
equity, environmental health and economic health of the community. The City of Fort Collins has developed a Sustainability Assessment
Framework that describes the purpose, objectives, and guidelines to assist City Program/Project Managers to determine:
• The process for cross-department collaboration in using the SAT
• Timing for applying a SAT
• When to apply a SAT
• How to document the results of the SAT and present at City Council Work Sessions and Regular Council Meetings
Further detailed guidance is available at: http://citynet.fcgov.com/sustainability/sustainabilityassessments.php
The SAT does not dictate a particular course of action; rather, the analysis provides policy makers and staff with a greater awareness of some
of the trade-offs, benefits and consequences associated with a proposal, leading to more mindful decision-making.
Brief description of proposal
To analyze a roundabout as the type of intersection at Lincoln Avenue and the north-south extension of “International Boulevard”. (This extension of
International Boulevard will be renamed in a future City Council action.)

Social Equity
Described: Placing priority upon protecting, respecting, and fulfilling the full range of universal human rights, including those pertaining to civil,
political, social, economic, and cultural concerns. Providing adequate access to employment, food, housing, clothing, recreational opportunities, a
safe and healthy environment and social services. Eliminating systemic barriers to equitable treatment and inclusion, and accommodating the
differences among people. Emphasizing justice, impartiality, and equal opportunity for all.
Goal/Outcome: It is our priority to support an equitable and adequate social system that ensures access to employment, food, housing, clothing,
education, recreational opportunities, a safe and healthy environment and social services. Additionally, we support equal access to services and
seek to avoid negative impact for all people regardless of age, economic status, ability, immigration or citizenship status, race/ethnicity, gender,
relationship status, religion, or sexual orientation. Equal opportunities for all people are sought. A community in which basic human rights are
addressed, basic human needs are met, and all people have access to tools and resources to develop their capacity. This tool will help identify how
the proposal affects community members and if there is a difference in how the decisions affect one or more social groups. Areas of consideration in
creating a vibrant socially equitable Fort Collins are: basic needs, inclusion, community safety, culture, neighborhoods, and advancing social equity.
Analysis Prompts
• The prompts below are examples of the issues that need to be addressed.
They are not a checklist. Not all prompts and issues will be relevant for any
one project. Issues not covered by these prompts may be very pertinent to a
proposal - please include them in the analysis.
x Is this proposal affected by any current policy, procedure or action plan?
Has advice been sought from organizations that have a high level of
expertise, or may be significantly affected by this proposal?
Proposal Description
To identify a roundabout as the preferred intersection control at Lincoln
Avenue and the north-south extension of “International Boulevard” (both
minor arterial roadways). (This extension of International Boulevard will be
renamed in a future City Council action.)
1. Meeting Basic Human Needs

RESOLUTION 2015-043
OF THE COUNCIL OF THE CITY OF FORT COLLINS
DETERMINING THAT A SINGLE-LANE, MODERN ROUNDABOUT IS THE PREFERRED
ALTERNATIVE FOR THE INTERSECTION OF LINCOLN AVENUE AND THE
NORTH-SOUTH EXTENSION OF “INTERNATIONAL BOULEVARD”
WHEREAS, the planned intersection of Lemay Avenue with the north-south extension of
“International Boulevard” (to be renamed by City Council Resolution in a future action) has been
identified as a possible intersection for implementation as a roundabout; and
WHEREAS, City staff has conducted an analysis of the establishment of a single-lane,
modern roundabout at said intersection in accordance with Resolution 2001-120, which calls for
an Intersection Alternative Analysis to be conducted before roundabout improvements are
approved; and
WHEREAS, the Intersection Alternative Analysis reviewed by City staff considers the
six criteria of safety, capacity, air quality, cost, alternative mode mobility and special
requirements, and concludes that the single-lane, modern roundabout design is favored or neutral
in every criteria; and
WHEREAS, the City Council’s determination of the appropriateness of a single-lane,
modern roundabout at this location is independent of the proposed Capstone Cottages
development that may construct it, and this determination will continue in effect regardless of the
outcome of that proposed development; and
WHEREAS, after public outreach and receipt of the recommendation from the
Transportation Board, the City Council has determined that a single-lane, modern roundabout at
the intersection of Lincoln Avenue and the north-south extension of “International Boulevard” is
in the best interests of the City and should be authorized.
NOW, THEREFORE, BE IT RESOLVED BY THE COUNCIL OF THE CITY OF
FORT COLLINS that the Intersection Alternative Analysis described in Resolution 2001-120
shows that a modern, single-lane roundabout is the preferred alternative for the intersection of
Lincoln Avenue and the north-south extension of “International Boulevard”, and that a
roundabout as described is appropriate for construction at that location.
Passed and adopted at a regular meeting of the Council of the City of Fort Collins this
21st day of April, A.D. 2015.
