TENW Transportation Engineering NorthWest Transportation Planning I Design I Traffic Impact & Operations 11400 SE 8th Street, Suite 200, Bellevue, WA 98004 I Office (425) 889-6747 MEMORANDUM DATE: October 20, 2017 TO: Larry Martin Davis Wright Tremaine LLP FROM: Cutis Chin, P.E. TENW SUBJECT: 2017 Updated RTC Traffic Counts Redmond Town Center TENW Project No. 5559 This memorandum documents a comparison of the entitled p.m. peak hour trips associated with the Redmond Town Center (RTC) development and the actual trips generated by the RTC site based on current traffic counts. The RTC site is located in downtown Redmond between Leary Way, Bear Creek Parkway, and NE 76th Street. This memo is an update to the previous trip generation analysis for the RTC site completed in 2001. Approved Trip Generation The approved master plan for the RTC site includes a cumulative p.m. peak hour trip generation of 3,336 driveway trips (2,367 net new trips + 969 pass-by trips). As a condition of the approved master plan, the RTC development was required by the City of Redmond to mitigate the off-site impacts associated with these trips. In addition to the p.m. peak hour trips associated with the approved master plan, 281 p.m. peak hour trips from the RTC West site (located west of Leary Way) were transferred to the RTC site in December 1998. Current Traffic Counts To determine the actual number of p.m. peak hour trips generated by the existing RTC site, a trip generation study was conducted in September 2017 (see Attachment The study was conducted in accordance with industry standards established by the Institute of Transportation Engineers (ITE). Data was collected for three consecutive weekdays (September 19 - 21, 2017) between the hours of 4:00 p.m. and 6:00 p.m. at all entrances providing access to the RTC site. At the time of the study, the RTC development included the following land uses: • 614,488 square feet of retail space • 687,453 square feet of office space • 308,000 square feet of hotel space The results of the trip generation study show that during the weekday p.m. peak hour, the existing RTC site currently generates 2,445 p.m. peak hour driveway trips. ---PAGE BREAK--- 2017 Updated RTC Traffic Counts Redmond Town Center TENW October 20, 2017 Page 2 Current Vacancy and Future Developments Vacancy rate information for the retail and mixed-use portion of RTC was provided by the property manager. At the time the study was conducted, vacant retail space included the former 35,000 SF REI. Excluding the former REI building, the current vacancy rate for the remainder of the development falls within the typical range of vacancy for similar development types and thus did not require any adjustment in the observed traffic counts. To account for the existing vacancy in the former REI building, trip generation attributable to the vacant former REI space was estimated based on methodology documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th edition for Land Use Code (LUC) 820 (Shopping Center). Additionally, trips associated with the currently under construction Archer Hotel (160 room hotel) and the future planned Redmond Town Center Apartments (mixed-use) project were accounted for in our trip generation analysis. Table 1 summarizes the estimated trips associated with the current retail vacancy and future development currently under construction or planned. Table 1 Trip Generation Current Vacancy and Next Phase of Development Development Size Weekday PM Peak Hour Trips Vacant Retail Space 35,000 SF 250 Archer Hotel (currently under construction) 160 Rooms 82 RTC Apartments (future planned project) 286 Units + 9,100 SF Retail 148 TOTAL 480 Summary Table 2 compares the entitled RTC trip generation (including the transfer of trips from RTC West) to the current traffic counts with additional trips to account for current vacancy and future development on the RTC site.
