the minimum acceptable performance standard (often described in terms of Level of Service standards or volume/capacity ratios). If a local government determines that an amendment would significantly affect a transportation facility, the local government must put in place measures to assure that the allowed land uses are consistent with the identified "function, capacity and performance standards" of the facility (OAR 660-012-0060(1)). An example of such a measure is conditioning approval on the construction of a minor street improvement. The applicant's March 8,2007, Traffic Impact Analysis (TIA) provided the traffic levels that would be generated by the uses in the approved PUD for Summer Oaks-Crescent Center and the traffic levels that the applicant anticipated would be generated by the land uses that the applicant would like to establish on the site. (Original TIA is dated January 4,2001, revised February 21,2001.) Regarding traffic generation estimations based on the approved PUD, the applicant's TIA provided traffic data for a 4-story, 80,000 s.f. office building and a 6,000 s.f. restaurant on the portion of the PUD site that is the subject of this application.\ In response to staff's request for additional information, on August 9, 2007, the applicant submitted a supplemental TIA. The August 9 TIA provided a comparison of "worst case" scenarios under the existing C-l designation and the proposed C-2 designation, and included data on existing levels of service (LOS) for nearby streets, and how those levels may be affected by traffic generated by allowable uses if the amendments and zone change were approved. All of the traffic impact data in the applicant's supplemental TIA relates to traffic conditions 2008. Based on the analyses in the TIA, the number of PM peak hour trips in 2008 if the site is developed under the current PUD approval (which could occur without the proposed amendments and zone change) ranges from 234 to 322. The number of PM peak hour trips anticipated in a worst case scenario under the existing C-l zone and plan designation is 714. The traffic generated by the proposed C-2 designation is anticipated to be 1,196 PM peak hour trips. Pursuant to Table 6 of the applicant's supplemental TIA, in 2008 the proposed amendment would significantly effect a transportation facility (Crescent A venue at Coburg Road). The applicant provides that "the proposed amendments will have a significant effect on the transportation system at the beginning of the planning period and thus at the end of the planning period. " To mitigate the proposed amendment's significant affect on the transportation facility the applicant proposes that the land use density and designation be required to limit the total number of PM peak hour trips, as measured by the ITE Trip Generation Manual, so as not to exceed the number of PM peak hour trips expected under the reasonable worst case under the existing C-l zoning. Specifically, the applicant proposes a trip cap of 1588 daily trips and 213 PM peak hour trips on future uses of the site to mitigate the effect of the proposed amendment on the impacted transportation facilities.2 The proposed trip cap reduces the number of trips to an amount less than is currently allowed under the existing C-l zone. Accordingly, it is reasonable to conclude that the net effect of the proposed plan amendment and zone change with the trip cap will result in an overall reduction in the total number of trips on the surrounding transportation facilities; thus, with the trip cap, the allowed land uses would be 1 The PUD for Summer Oaks-Crescent Center approval is currently in effect and governs development on this site. All new uses proposed for the site will be required to comply with the existing PUD; any significant change will require a new PUD. The proposed zone change to C-2 would accommodate the property owners' plans for a new extended stay hotel of approx. 100,000 s.f. (139 units), and a catering business of approx. 15,000 s.f., with 10,000 s.f. of office and 5,000 s.f. of specialty retail. 2 The applicant's new desired uses for the site (hotel and catering business, etc.) are expected to generate up to 300 fewer daily vehicle trips than the approved PUD, and up to 27 fewer during the PM peak hour, with an expected 213 PM peak hour trips. While these uses were the basis for the applicant's proposed trip cap, the trip cap would apply to any future uses on the site.
