Mr. Mike Harrah Caribou Industries, Inc. March 9, 2020 Page 2 of 6 13141-04 TG Letter The trip generation from the 2002 Traffic Study was calculated based on the Institute of Transportation Engineers (ITE) Trip Generation Manual, 6th Edition (1997) and the ITE Trip Generation Handbook – An ITE Proposed Recommended Practice (October 1998). As shown in Table 2, the 2002 Traffic Study concluded that the Project would generate 6,686 trip-ends per day, with 744 trips generated during the AM peak hour and 819 trips generated during the PM peak hour. TABLE 2: CURRENTLY APPROVED PROJECT TRIP GENERATION SUMMARY PROPOSED PROJECT The Project is proposing to develop a mixed-use development with both residential and office uses at One Broadway Plaza. The Project requires a General Plan Land Use Element amendment to permit residential development within the OBPDC. The One Broadway Plaza building includes 518,000 square feet of office uses. Approximately 50% (254,472 square feet) is proposed for a total of 402 apartment units. Table 3 presents the trip generation rates obtained from the ITE Trip Generation Manual (10th Edition, 2017) for the proposed multifamily housing use and the remaining other office, retail, and restaurant uses originally contemplated. The ITE trip generation rate utilized for the multifamily housing is for developments located within City Center Core areas (as opposed to rates for developments within a general urban/suburban setting). The average rates for General Office uses located within City Center Core areas has also been utilized to estimate the trip generation for the office uses proposed in the tower, while the average rates for General Office located within general urban/suburban areas have been used to estimate traffic for the rehabilitated structures. The latest ITE Trip Generation Manual does not provide any trip rate data for Specialty Retail, as such, the average rates for the Shopping Center land use (ITE Code 820) have been utilized. Similar to the 2002 Traffic Study, an AM inbound and outbound split is not reported for the Quality Restaurant land use. As such, a 50%/50% split has been assumed for the AM peak hour, consistent with the 2002 Traffic Study.
