Traffic Impact Analysis Riverview Apartments Project Trip Generation Trip generation rates compiled by the Institute of Transportation Engineers (ITE) Trip Generation, I& Edition, 2017, were used to estimate daily, a.m. peak hour, and p.m. peak hour traffic that would be generated by the proposed action. Fitted curve equations for the Mid -Rise Apartments (ITE Land Use Code 221 were applied without any discount given the affordable nature of the housing units) for the proposed use and rates for Single Family Homes (ITE Land Use Code 210), Building Materials Store (ITE Land Use Code 812), and local rates for Drive-Thru Coffee (ITE Land Use Code 937) were used to estimate net new trips generated by the proposed development. Table 3 summarizes estimated trip generation by the proposed action. An estimated total of 766 daily, 51 a.m. peak hour trips (9 entering and 42 exiting), and 68 p.m. peak hour vehicular trips (44 entering and 24 exiting) would be generated at full build -out of the project. A detailed summary of trip generation calculations is provided in Attachment C.

Generally, distribution and assignment of project trips were assumed as: ➢ 15 percent north E Marine View Drive; ➢ 20 percent west via 16th Street and 5 percent west via Summit Ave/ 19th Street; ➢ 45 percent via 1-5 to/from the south; and ➢ 15 percent south E Marine View Drive/E Grand Avenue. Figure 4 illustrates trip distribution during the p.m. peak hour at the study intersections the 2020 horizon year. Figure 5 summarizes traffic volume impacts of the proposed Riverview Apartments project during the p.m. peak hour in 2020. Detailed turning movement forecasts are provided in Attachment D. Intersection Level of Service Impacts Table 4 summarizes level of service impacts in 2020 assuming full buildout of the proposed Riverview Apartments project. As shown, in 2020 all study intersections are projected to operate at LOS C or better with or without the project, meeting adopted level of service standards. Detailed LOS summary worksheets are included in Attachment B. TEN W April 10, 2018 Page 7
