<br />Marian Meadows Rezone and Subdivision Final Environmental Impact Statement 3-66 <br />Vehicle trips generated by the future 2020 Alternative 1, Tenure Scenario 1 scenarios were based on the <br />trip generation data provided for single-family residences in the Institute of Transportation Engineers <br />(ITE) Trip Generation, 7th Edition. The PM peak hour trips generated are summarized in Tables 3-6 <br />and 3-7. <br />Table 3-6.

Ten percent of the project trips are expected to use Country Drive to access the <br />development and the other 90 percent are expected to use the proposed access road from the property to <br />Sparks Road. The following trip distribution percentages were obtained from a previously prepared <br />traffic impact study (TENW 2006) and were used to assign the new trips to the study area: <br /> 35 percent to/from Railroad Street <br /> 35 percent to/from eastbound I-90 <br /> 30 percent to/from westbound I-90 <br />Based on this trip generation and distribution, traffic volumes would substantially increase in the study <br />area. Under the No Build Alternative (Figure 3-10), the PM peak hour traffic volume along Sparks Road <br />at Railroad Street is expected to be 144 vph in 2020, a negligible increase over existing volumes. For a <br />226-lot subdivision, this volume is expected to increase to 367 vph as indicated in Figure 3-11, which is <br />about two and a half times greater than the existing volume. With full buildout of the PUD, the PM peak <br />hour volume along Sparks Road would reach 552 vph as shown in Figure 3-12, or about three and a half <br />times greater than the existing volume.
