ARCHITECTS/PLANNERS CONSTRUCTION MANAGEMENT 135 West Swallow Road Fort Collins, CO 80525 April 4, 1988 (303) 223-7335 Mr. Rick Ensdorff City of Fort Collins Traffic Department Box 580 Fort Collins, CO 80522 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. SITE SUMMARY Car Wash: 8 Cars Washing 8 Cars Vacuuming 8 Cars Stacking - Auto Bay 14 Cars Stacking - Self -Serve Detail Shop 4 Cars Inside 4 Cars Waiting Lube Shop 3 Cars Inside 3 Cars Completed (Out Cycle) 12 Cars Stacking Parking On Site 14 Cars Mr. Rick Ensdorff April 4, 1988 Page 2 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.
