FORT COLLINS CITY COUNCIL STAFF:
Eric Bracke
SUBJECT:
Postponement of the Second Reading of Ordinance No. 112, 2000, Appropriating Unanticipated
Revenue in the Transportation Services Fund State Highway 14 and Lemay Avenue Intersection
Project, until September 19.
RECOMMENDATION:
Staff recommends postponing the Second Reading to September 19.
EXECUTIVE SUMMARY:
On January 18,2000,the City Council voted unanimously to move ahead with a modem roundabout
at the intersection of State Highway 14(SH 14)and Lemay Avenue.The decision was based on the
superior performance of the modern roundabout in virtually all aspects of the evaluation criteria.
On June 9, 2000, the Colorado Department of Transportation (CDOT) gave its approval of the
modern roundabout contingent upon entering into an Intergovernmental Agreement with the City
regarding the operation and maintenance of the intersection. Ordinance No. 112, 2000, which was
unanimously adopted on First Reading on August 15, 2000, appropriates unanticipated revenue to
be used to construct improvements associated with the roundabout for the State Highway 14 and
Lemay Avenue Intersection project.
Because the final costs for the Wal-Mart development have not been fully determined, staff
recommends that the Second Reading of Ordinance No. 112, 2000 be postponed to September 19.

SUBJECT:
Items Relating to the Proposed Roundabout at the Intersection of State Highway 14 and Lemay
Avenue.
RECOMMENDATION:
Staff recommends adoption o e Reso tion option yofeOrdinance on First Reading.
FIVtAf�a'. s opinttoof ft rIN financial obligations or risk for the City to bear regarding the Intergovernmental Agreement with
CDOT are minimal. The IGA states that the City will fund the replacement (estimated at $1.5 million) if the roundabout
should fail to operate within certain parameters in the first five years. In years 6-10, the City agrees to share equally with
CDOT the replacement of the roundabout i uld as Pya
ummary below. There are other normal
operating costs such as snow removal,si g an s ing City now maintains on the state highway
ystem within the Urban Growth Area.
The$1,000,000 in revenue is the Mulberry-Lemay Crossings contribution to the project.The$1,000,000 includes $800,000
in roadway improvements and utility work,and$200,000 as the developer's share of the cost of the pedestrian bridge over the
Poudre River, that the developer is responsible for if we were building the traditional four-lane arterial/arterial intersection

BACKGROUND:
On January 18,2000,the City Council voted unanimously to move ahead with a modern roundabout
at the intersection of State Highway 14(SH 14)and Lemay Avenue.The decision was based on the
superior performance of the modem roundabout in virtually all aspects of the evaluation criteria.
On June 9, 2000, the Colorado Department of Transportation (CDOT) gave its approval of the
modern roundabout contingent upon entering into an Intergovernmental Agreement with the City
regarding the operation and maintenance of the intersection. Stated below is a summary of the terms
of the recommended IGA.
DATE: August 15, 2000 2 ITEM NUMBER: 37 A-B
Section 1: The City has agreed to maintain a contractual relationship with roundabout design
expert,Mr. Barry Crown of the United Kingdom, for a three-year period. If any adjustments to the
roundabout are necessary such as deflection or striping changes, Mr. Crown will assist the City in
making the appropriate adjustments. (It is staff's intention to keep Mr. Crown on a retainer basis
regardless of the IGA provision.)
Section 2: The financial risk of this IGA is found in this particular section. The City is agreeing
to replace the roundabout with a standard four-lane design, signalized intersection if it should fail
according to the agreed upon criteria within the first five years of operation. If the roundabout
should fail in the 6th through loth year, the City and CDOT will share equally in the cost of
replacing the intersection. The Qpst-4thwerive t ti n today's dollars is estimated
at $1.5 million.
If for some reason the City has ce n ut,the would use any source available,
including Federal funds, to pay for the project.
Section 3: This section of the IGA defines"failure"as it pertains to Section 2. Failure has been
defined in terms of accidents and delay time. As for the accident failure,the intersection currently
has an accident rate of 1.9 accidents per million vehicles entering the intersection and staff has
stated that if the accident rate exceeds 2.0 per million, Barry Crown will be consulted for an
evaluation. City staff does not believe that this issue will arise. In all of the research conducted by
the staff and the Federal Highway Administration,accidents always decrease by up to 60%with the
installation of a roundabout. Cretiso )eay
da dr n as to assume this roundabout will
increase the accident rateThe second area of failure deamen evels of service. The modeling estimates that
the roundabout will fall well within the City's Level of Service (LOS) guidelines and out-perform
the traditional intersection design. The traditional four-lane intersection is expected to fail at peak
periods within a 7-10 year time period,and the roundabout is predicted to operate at LOS B or better
during the peak hours throughout the 20-year time period. This far out-performs any intersection
that the City has operating today. As CDOT and the City evaluate the actual operation of the
roundabout,the LOS analysis must show that a traditional intersection would operate better than the
roundabout for failure to occur. Throughout the City's analysis, staff consistently found that
congestion and delay were Sig ' ' y bo over a signalized intersection.
Staff believes that the risk of ilure is trem tiimal, es cially in the short-term (10 year)
time frame. Staff estimates tha oun t ave b n a 20 and 30 year life. Normal
design life is calculated at 20 years.
Section 4: This particular section is in regards to the 3/4 access on Mulberry at 12th Street
(access to Super Market Liquor). The roundabout/intersection design allows for an eastbound left
turn into 12th Street. If the left turn becomes problematic, the city has agreed to eliminate this
movement.
As an informational item, the design of the roundabout also necessitates a minor revision to the
recently adopted Mulberry Street(State Highway 14)Access Management Plan. This revision is for
the 3/4 access on the south side of Mulberry Street (SH14), which currently exists approximately
500 ' east of Lemay Avenue. The roundabout design requires that this 3/4 access be shifted

approximately 200' eastward in order to provide sufficient distance for deceleration lane design
requirements.
Section 5: This section addresses the maintenance of the roundabout in areas such as signing,
striping, landscaping, sweeping, etc. These maintenance costs are minimal and the City already
maintains much of the state highway system in Fort. Collins under contract with CDOT. The
maintenance includes such things as potholes but not any major items such as overlays.
Section 6: The City has agreed to develop an Incident Management Plan for the roundabout.
This plan will be written in cooperation with CDOT, Poudre Fire Authority, Police Services,
Sheriff's Department, and the o a i accident in the roundabout,
emergency response personne ill ha a ecifi eli s al/in agreement on how to clear the
roundabout efficiently. IL
Section 7: An intensive public outreach program has begun that is aimed at keeping people
informed of the roundabout progress and how to drive roundabouts safely and effectively. The
program also requests that the State Department of Revenue add provisions in the drivers' manual
on roundabouts.
Sections 8 and 9: These paragraphs protect both the City and the State from violating the
TABOR Amendment to the Colorado Constitution that prohibits multi-year fiscal obligations.
In summary, roundabouts hav en p in to do o the world to reduce congestion,
accidents, and air pollution o r stand sign rsec s. The risk that the Fort Collins
roundabout at the intersection ul and will fail a agreed-upon criteria is less than
minimal. One of the best experts in the fie as been hired to assist the City in this endeavor, and
staff is confident that the project will be a success.
Item `B" deals with appropriating revenue from the Mulberry-Lemay Crossings project in the
amount of $1,000,000. These are the funds that the developer agreed to pay to the City if this
project were being built as a traditional intersection. Congestion Mitigation and Air Quality funds
(CMAQ) and Street Oversizing funds are paying for the remaining portion of the project (total
estimated cost is approximately $2,000,000). The remaining part of the project budget was
appropriated last fall. COPY
