RE: Cherry Springs Trip Generation
The following provides a trip generation estimate for the proposed Cherry Springs Apartment
complex in Springfield, OR. The proposal is 129 apartment units contained within 16 buildings.
Each building contains 8 units, and there will be one building containing the office and one
residential unit.
The ITE Trip Generation Manual 10th Edition is used to estimate the trip generation for the AM and
PM peak hours and daily trips. ITE Land Use Code 220 Multi-Family Housing (low-rise) is the most
appropriate land use as the proposed development will contain buildings with at least three other
dwelling units and has no more than two levels. The trip generation estimates are shown in Table
1. The estimates use the fitted curve equation as it meets the applicable ITE criteria for use.
TABLE 1: TRIP GENERATION ESTIMATE
Time of Day Units Rate Trips
AM Peak Hour 129 ln(t)=0.95ln(x)-0.51 61
PM Peak Hour 129 ln(t)=0.89ln(x)-0.02 74
ADT 129 T=7.56(x)-40.86 934
As demonstrated in Table 1, the City of Springfield TIA threshold of 100 peak hour trips or 1000
ADT daily trips is not met.
The site was previously subject to a trip cap on the site of a total of 162 PM peak hour trips. The
PM peak hour trips for this proposal is 74 trips resulting in 88 PM peak hour trips for the remaining
undeveloped area.
