Subject: Brice PUD traffic study
(File: 9219MEM1)
The Brice PUD is a dentist office located on the
northeast corner of the McHugh/Elizabeth intersection in Fort
Collins. The current use is that of a dentist. It is
proposed that a second dentist be added to this building.
Since this is a single family residence converted to a dentist
office, the City .of Fort Collins has requested a PUD review
of this use with this proposal.
Trip generation information was requested by the City.
It was investigated using scheduling data from the existing
use and Trip Generation, 4th Edition, ITE, 1987. The
scheduling data yielded the highest rate and was, therefore,
used. Table 1 shows the trip generation which occurs on the
two highest days of the week when the full complement of
employees is at the office. Other days of the week would be
lower. There are three operatory stations at this building
with no plans to increase this. Therefore, the patient load
could not be higher than the present highest load with one
dentist and two hygienists. The additional dentist would
allow this highest daily load to be extended to the other
three days of the week. It would also allow for potential
evening and Saturday appointment hours. On a given day, the
trip generation would not be different than that which
currently exists.

n the driveway, the

remainder of the
employees park on the street to the south of this office. There
are six spaces marked in the driveway that are used by patients.
It is recommended that the parking layout in the driveway be
changed as indicated in Figure 1. It is recommended that the six
spaces on the west side of the driveway be striped to have five
spaces. This will allow 9 foot wide stalls. The one space
adjacent to the sidewalk can be striped "no parking," which
improves sight lines to the west and will have less impact on the
sidewalk. Since the garage is used by employees, the spaces in
front of the garage can be striped as patient parking. This
parking scheme will increase the number of designated patient
parking spaces from 6 to 7. Comparing the trip generation and the
recommended parking scheme, there appears to be adequate on -site
parking.
I made a site visit to check sight lines and observe
conditions. During the period of my site visit, there were no
patient vehicles in the driveway. There were vehicles parked on
McHugh to the south of the office. There is three-way stop sign
control at this intersection. The existing dentist office driveway
comes off McHugh opposite Elizabeth Street. Traffic volumes in the
area are light. Even with increases forecasted in the area,
traffic will be light from an operations perspective. Operation
will be acceptable (level of service A) using the forecasted
traffic with the three-way stop control.
Fort Collins street standards indicate that the corner sight
distance on local streets should be 300 feet. This cannot be
physically achieved. However, the two recommendations below, along
with the elimination of the driveway parking space closest to the
street, will maximize the available sight distance.:
- There is a short segment of curb between the Brice driveway
and the driveway of the property to the north. This should
be designated "no parking."
- The curb area on the east leg of McHugh approaching the stop
sign should be designated "no parking." Due to the horizontal
curve, this no parking area should extend approximately 30
feet from the stop sign.
These recommendations are shown graphically in Figure 1. Given the
three-way stop condition, adherence to the 300 foot sight distance
standard is not critical.
During my site visit, it was noted that the driveway ramp is
approximately 35 feet wide. For the amount of traffic using this
driveway and in consideration of its location with respect to the
intersection, it is recommended that the ramp area be narrowed to
about 20 feet. This will direct ingressing and egressing vehicles
to a smaller area which will better control vehicle operation at
the driveway.
