Subject: Trip Generation Letter
AAA Car Wash - Ogden, North Carolina
Dear Mr. Simmons:
This letter provides trip generation information for the proposed AAA Car Wash site proposed along Market
Street in Ogden, North Carolina. The proposed development is anticipated to consist of an automated car wash
and car care facility.
Average weekday daily, AM peak hour, PM peak hour, Saturday daily, and Saturday peak hour trips for the
proposed development were determined by the NCDOT based on methodology contained within the ITE Trip
Generation Manual, 9th Edition. Table 1 provides a summary of the trip generation potential for the proposed
development. It should be noted that Table 1 provides two alternatives for the automobile care/service portion
of the development. As shown in Table 1, the alternative using land use code 943 results in a total Saturday
peak hour trip generation of 105 trips. The weekday AM and PM peak hour trip generation is less than 100
peak hour trips. The trip calculations in Table 1 do not account for the reduction in trips that occur for the
current use.
The property is currently occupied as a landscaping nursery. Since these trips will be removed when the new
AAA car wash is constructed, the existing trips were calculated and subtracted from the new trip generation to
determine the net trip increase on the roadway network. Trips for the existing nursery use were calculated
based on methodology contained within the ITE Trip Generation Manual, 9th Edition. The total number of
acres of the nursery property were estimated based on New Hanover County GIS property data.
As shown in Table 2, it is estimated the nursery site currently generates a total of 58 peak hour trips on a
Saturday. Weekday AM and PM peak hour trips are much less. Also shown in Table 2 is the net new trips that
would be added to the roadway network. The net new trips were calculated by subtracting the existing trips
(nursery) from the proposed trips (AAA car wash). As shown in Table 2, the net new trips are well below the
City’s threshold for requiring a Traffic Impact Analysis (TIA), which is 100 peak hour trips.
