Traffic Analysis
November 9, 2012
Introduction
The purpose of this analysis is to provide an evaluation of the traffic impacts of the proposed
re‐model of the Vail Golf Course Club House. The re‐model project involves a relatively small
increase to the size of the Club House from 18,667 SF to 21,627 SF. All current uses within the
existing Club House will be maintained and no new uses will be added as a result of this re‐
model. A more detailed discussion of the use of the Club House is provided below.
Existing Conditions
Access to the subject site is provided by Vail Valley Drive/Sunburst Drive (herein referred to as
Sunburst Drive). Sunburst Drive is a two‐lane road that dead‐ends approximately ½ mile past
the Club House. Bike lanes are striped on both sides of Sunburst Drive from the intersection of
Vail Valley Drive and Sunburst to just past the Club House.
Between the Frontage Road/Vail Valley Drive intersection to the Club House there is only one
stop‐sign controlled intersection (Vail Valley Drive and Sunburst). There are five private
driveways that intersect with Sunburst Drive along this same section of roadway. In addition to
the Vail Golf Course, Sunburst Drive provides access to approximately 139 residential units and
a small amount of office use (in Fall Ridge Condominiums).
There are no current traffic counts available for Sunburst Drive.
The Vail Golf Course is an 18‐hole public golf course with a driving range, pro shop locker
rooms, a 120 seat restaurant/bar and an auxiliary meeting room when combined with the
restaurant can seat up to 140 persons for banquet functions. In winter months the Vail Nordic
Center operates out of the Club House, however traffic related to the nordic center is
significantly less than what is generated by the golf course and as such the focus of this analysis
is on the summer use of the Club House.
Vail Golf Course Existing Traffic Generation
The Institute of Transportation Engineers (ITE) Trip Generation 6th Edition includes trip
generation rates for a wide variety of different land uses. These generation rates are based on
actual traffic counts and reflect weighted averages for the peak hour of the land use. The ITE
trip generation rate take into account all trips to the subject land use including employees,
deliveries and other uses as listed in the description for each land use.
“Golf Course” is a land use (430) in the ITE reference . The description is as follows:
“The golf courses contained in the land use include 9, 18, 27, and 36, hole
municipal courses and private county clubs. Some clubs have driving ranges and
clubhouses with a pro shop and/or restaurant, lounge and banquet facilities.”
The Vail Golf Club uses are consistent with the land use description in the ITE manual.
Golf courses are a unique land use in terms of estimating trip generation. The following
evaluations have been completed in order to estimate existing peak hour trip generation from
the Club House.
ITE Saturday Peak Hour
The ITE trip generation rate for a Saturday PM peak hour is 4.59 trips per hole x 18 holes, or 83
total trips with 49% entering and 51 % exiting. This peak would occur in the early afternoon as
verified with Vail Golf Course use numbers.
ITE Weekday Peak Hour
The ITE trip generation rate for the 4‐6 pm period during weekdays is 2.74 trips per hole x 18
holes or 49 total trips.
The ITE PM peak hour trip generation rate is greater than the ITE PM peak hour trip generation
rate between the hours of 4pm‐6pm. This trend is similar to the Vail Golf Course as the peak
golf course activity times occur during the late morning‐ early afternoon time frame.

Even though the ITE rate for Golf Course describes the existing and proposed facilities exactly, a
comparison analysis is provided here to better under stand the trip generation as it relates to specific
operations in Vail
At the Vail Golf Course there are shot gun start tournaments where the golf course itself generates a
significant amount of traffic in the peak hour. A typical 140 person tournament with a 1.5 person per car
average would generate 93 vehicular trips just by itself. Whereas the typical hour of turnover of the golf
course is only 48 golfers. At 1.5 persons per car this generates 32 vehicles trips for typical golfer
turnover.

Existing Banquet Facility
Looking then at the banquet use separately, contrary to the ITE rates, one could add additional trips.
The current Golf Clubhouse with a 120 seat restaurant and bar with the additional capacity of the
Krueger room provides 140 seat capacity, for sit down functions and the existing capacity for receptions
is well over 200 people. There is little data on the average use, but it is assumed to be around 100
people. This would generate an additional number of evening (4pm – 6 pm) peak hour trips calculated as
follows: 100 people/3 people per car or 33 vehicle trips for functions.
This was compared to a known banquet use at the Donovan Park Pavilion. The average function size at
this facility is between 140‐150 people of the 250 advertised capacity. Most all functions start within the
4‐6 pm time frame, based on information provided by Donovan Management the arrival of patrons to
the facility averages 3 per car, as assumed above. The average wedding party is approximately 140
people with a noted 45 cars in the parking lot.
By combing both the typical golfer turnover and estimated banquet use trip the existing peak hour trip
generation of the Golf Course and Clubhouse during an event during the hours of 4pm‐6pm is 49 trips
for the golf course and 33 trips for the banquet function for a total of 82 trips. This is similar to the ITE
rate for Saturday peak of the golf course demand, therefore we believe the more specific comparison
assumptions and relations are appropriate.

Proposed Conditions/Traffic Generation
The remodel includes a new, dedicated banquet room. The banquet room is expected to host a variety
of functions, including but not limited to banquets, receptions, parties, lectures and other community
events. Occupancy of this room is capped at 200 persons. For the past thirty years to the present time
the 120 seat restaurant/bar of the existing Club House along with the Krueger Room has hosted these
same functions. As previously stated the capacity of this existing space for sit‐down dinners is 140
people and the existing capacity for receptions is well over 200 people. As such, the “peak event” at
the existing Club House could be larger than what could occur in the new banquet room.
In the recent past approximately 25 functions per year have been held in the restaurant space. Planners
for the remodeled Club House anticipate 60‐70 functions per year in the new banquet room. . So there
is an expectation of more frequent functions in the remodeled Club House. Seventy Five percent of all
functions will be occurring in the months from May to October.
The new banquet room, would cap the peak capacity to 200 persons with an average of events being
130 persons. The 200 peak persons would be equivalent to the current situation. Using the banquet
specific trip generation methodology described above for the average peak hour trip generator the
calculation would be as follows: 130 persons arriving at a rate of 3 people per car is equal to 43 evening
(4‐6pm) vehicular trips. The increase in average peak hour traffic demand is the difference between 43
and 33 trips or 10 additional trips in the peak hour during events.
A conservative total average evening (4‐6pm)peak hour trip generation of the Golf Course, combining
both the ITE rate and an additional banquet room facility, is 49 golf course trips (ITE) plus 43 banquet
room function trips or 92 trips. This is an increase of 10 trips over the existing evening (4‐6pm) period. It
is also similar to the shot gun start tournament scenario.

Nordic
There are no ITE trip generation rate references for Nordic Centers. The Nordic Center generates
significantly less traffic than the golf Course operations and its operation in the winter does not conflict
with Golf Course operations, as such was not analyzed any further with regard to peak traffic
generation.
Bicycle and Pedestrian Traffic
The Town’s existing Gore Valley Trail bike path currently runs along this section of Sunburst Drive. It is
not expected that the remodel of the Golf Course will add to bicycle and pedestrian traffic along the
Gore Valley Trail. It is suggested that “Share the Road” signs be placed on Sunburst Drive to warn
motorists of the bicycle traffic.
Effect on Local Road System
Based on road capacity standards. Sunburst Drive in its existing condition is capable of accommodating
the potential traffic increase from the proposed remodeling of the Vail Golf Course Club House.Nordic
There are no ITE trip generation rate references for Nordic Centers. The Nordic Center
generates significantly less traffic than the golf Course operations and as such was not analyzed
any further with regard to peak traffic generation.
