operating conditions. From a traffic operations perspective, all
of the intersections meet City of Fort Collins standards.
Improvements
The road improvements that will be done by this development
are:
1. Widen Douglas Road from the site access road to SH1. This
widening will provide a 36 foot width for Douglas Road,
including striped bicycle lanes on both sides of the street.
2. Construct a site access road from the property to Douglas
Road. This access road will be a collector street that will
intersect with Douglas Road approximately 1200 feet east of
CR13.
3. County Road 13 will be paved adjacent to the site to a width
of 24 feet, with a sidewalk on the project side (east) of the
road.
4. If not already built as part of the Richard's Lake Development
to the southeast, a collector street will be constructed that
connects .to CR11. This connection will occur when the
Hearthfire PUD reaches 90 dwelling units.
In addition to the above, the following road improvements are
planned and/or designed to be constructed in the near future:
1. Improvements to the SH1/Douglas intersection include the
provision of auxiliary lanes on a number of legs of this
intersection. These improvements are being funded by private
developers and Larimer County.
2. Improvements to the US287/SH1 intersection include
realignment, geometric, and signal changes. The improvements
are intended to improve the operation at this intersection.
This intersection improvement will be completed prior to
occupancy of any dwelling unit in the Hearthfire PUD. This
improvement is funded by public entities, primarily the
Colorado Department of Transportation.
Traffic Impacts
The Hearthfire PUD will impact area streets and intersections.
Prior to the completion of the street connection to CR11 (through
the Richard's Lake Development), the site generated traffic will
utilize Douglas Road and CR13. Most of the "attractions" for
future residents of Hearthfire will be in and toward the central
area of Fort Collins. This includes the downtown area, CSU, and
points to the south along College Avenue. Based upon travel time
studies, the shortest route is via Douglas Road/SHl/College Avenue.
Some traffic will use CR13/Gregory/Lemay because of a perceived
lower travel time. This was considered in the traffic study.
Other Traffic
In conducting operational analyses at various intersections
and on various road segments, traffic from other known proposed
developments are included as part of the background traffic.
Background traffic is defined as traffic that is or will be on the
road system that is not attributed to this (Hearthfire PUD)
specific development. In addition, some growth of the existing
traffic is also included. This is generally done by factoring the
existing traffic by an annual percentage rate, typically 2-4
percent depending upon location. This allows for isolated homes
that are not part of a larger known development.
Level of Service
The concept of level of service uses qualitative measures that
characterize operational conditions within a traffic stream and
their perception by motorists and passengers. The descriptions of
individual levels of service characterize these conditions in terms
of such factors as speed, travel time, delay, freedom to maneuver,
traffic interruptions, and comfort and convenience. Level of
service is designated by letters A through F. Level of service A
represents the best operating conditions and level of service F
represents the worst operating conditions. There is also a range
of operating conditions within each level of service category.
The City of Fort Collins has established level of service D
as the minimum acceptable level of service at signalized
intersections, with the exception of arterial intersections along
commercial corridors and intersections with activity centers. The
minimum acceptable level of service at arterial intersections
within these areas is level of service E.
Tables 1 and 2 show the intersection level of service in the
respective short range and long range futures with the improvements
described below. As can be seen in these two tables, the operation
at the key intersections is acceptable, with most movements in
level of service categories A and B, which represent the best

Trip Generation
The Hearthfire PUD is proposed to consist of 148 single
family detached dwelling units. By City of Fort Collins
traffic study guidelines, the reference document Trip
Generation, 5th Edition, ITE is used to determine the expected
vehicle trips to/from a proposed development. The single
LLB
family dwelling unit use is the highest residential trip
generator from the reference document. It is expected that
