Vantage Bay PUD <br />Updated Traffic Impact Study <br /> <br /> <br /> TENW September 1, 2017 <br />Page 4 <br /> <br />Operations of Proposed Access <br />The operations of the proposed access on Huntzinger Road including level of service (LOS) and queuing are <br />not expected to be an issue. This assessment is based on the 2019 projected ADT of 453 vehicles on <br />Huntzinger Road. Using a K factor (proportion of daily traffic occurring in the analysis hour) of 0.10, the <br />estimated peak hour volume on Huntzinger Road would be approximately 45 vehicles. With a peak hour <br />volume of 45 vehicles on Huntzinger Road, we would not expect LOS or queuing to be an issue with the <br />additional traffic from the proposed Vantage Bay PUD development. <br />Summary/Conclusion <br />Based on the analysis included in the memorandum, the greatest number of peak hour trips is estimated to <br />occur on a Saturday. During the peak hour of the generator on a Saturday, the Vantage Bay PUD <br />development is estimated to generate 215 peak hour trips (114 entering, 101 exiting). Based on guidelines <br />included in the WSDOT Design Manual, turn lanes would not be recommended on Huntzinger Road along <br />the project frontage. The operations of the proposed access on Huntzinger Road including LOS and queuing <br />are not expected to be an issue. <br />If you have any questions with the information presented in this memo, please feel free to contact me at (425) <br />250-5003 or chin@tenw.com. <br /> <br />cc: Matt Reider – ESM Consulting Engineers, LLC <br /> Jeff Haynie, P.E. – Principal, TENW <br /> <br />Attachments <br /> <br />Index #5
