RE: EXECUTIVE AUTO CENTER
WEST HARVARD
FORT COLLINS, COLORADO
This letter provides traffic data for the proposed expansion of the Execu-
tive Car Wash located between College Avenue and McClelland on West Harvard.
West Harvard is improved to �0' with curb, gutter and sidewalk. Currently
there is parking on both sides of the street. As a part of our submission
and on behalf of the owner, we request that parking be omitted on the car
wash side (South side) of the street. It is the owner's believe that this
could reduce any potential traffic conflict with the curb cuts and improve
visibility for users entering or leaving the site.
As I mentioned, the 8-bay car wash currently is in operation and has been
for several years. As a part of the expansion, one self-service bay will be
changed to an auto bay. Traffic circulation on site will be basically from
East to West. Vacuums will be relocated to the outgoing sides of the car
wash to increase stacking on site. It is estimated that we can accommodate
eight cars stacking for the auto bay and fourteen cars stacking for the self -
serve bays without causing a backup situation with the lube shop.
The lube shop can accommodate twelve cars in stacking. Employee and custom
parking is provided on site. Since the detail shop is by appointment only,
we have not provided any stacking except that one car can park in front of
each detail bay.

TRIP GENERATION
A. 1-Bay Full Service Automatic Wash:
Operational data indicates that this facility has its peak usage on
Saturdays. Sunday operation would be similar. During the week the us-
age would be less than on Saturdays. The anticipated wash time for
this type of auto bay is four minutes. A 10-hour operation day is used
with 5 hours peak usage. This bay would service 15 cars per hour total-
ing 75 cars per peak five hours. The remaining 5-hour period would
handle seven cars per hour or 35 cars per average 5-hour period.
B. 7-Bay Self -Serve Car Wash:
Again data indicates that peak days occur on Saturdays and Sundays which
are outside of normal working day business hours. The Institute of
Transportation Engineers Trip Generation Summary indicates an hourly
peak of 60 trips to and from the site for an 8-bay car wash. Since we
have seven operational bays, we anticipate 52 trips to and from or 26
cars per hour. One car in each bay every 16 minutes with a 14-car
stacking, 7-car washing, 8-car vacuuming, and 8-car drying up to 37 cars
can be handled on site at any one time. With an average wash time of
six minutes per car, 70 cars can be processed in one hour with 14 cars
waiting.
We could anticipate that this peak loading would occur for a couple of
hours on a few days a year, typically the first weekend which is sunny
following a snow fall or in early spring, but realistically a 5-hour
rush at this volume would be maximum expected. For the remaining 5-
hour period it is expected that 30 trips to and from the site would be
normal, or 15 cars per hour.
C. Detail Shop:
This building functions as an installation garage only. This service is
directly related to the car wash. No service would be performed without
the full -service cleaning process. The owners predict three bays requir-
ing two employees. Six to eight cars per day would be considered a good
trade for this type of use. A total of two cars per hour during peak
periods and one car per hour for normal periods are used.
D. Lube Shop:
The lubrication use would have 3-work bays plus a lobby -sales area. We
see the building operating one 8-hour shift six days a week. Again we
can predict a Saturday peak use for this building and depict the traffic
for the maximum functions. Four employees will contribute 12 average
daily trips to the traffic flow above the building generation or traffic
to the sites. Assuming a turn over of five cars/hour, that is one car
every 12 minutes, in the three bays and this turn over rate occurs for
five hours per day. This contributes 75 average daily trips. The re-
maining operation time could yield two cars/hour/bay which would be 18
average daily trips.
