<br /> Figure 4 provides a snapshot of Table 11. The table shows that for the 1995 Proposed
<br /> Action with 33,500 employees, the PM peak hour trips would be 2,700 inbound and
<br /> 9,615 outbound, which added together results in 12,315 total PM peak hour trips.
<br /> Figure 4-DEIS Section 4.2.2 & Table 11
<br /> 4.2.2 Traffic volumes
<br /> Trip generation rates are assumed to follow current patterns. Because of the increase in site
<br /> employment,there would be a substantial increase in the tips generated,as shown in Table 11.
<br /> Note that because of a decrease in employment in the year 2000,there could be a slight decrease
<br /> in trip generation as compared to 1995.

<br /> Note also that Section 1.4.2 shown in Figure 3 above cites 9,400 current trips which is a
<br /> rounding of the 9,430 calculated for 1989 peak employment from Table 1 1 (2,065 +
<br /> 7,365 = 9,430).
<br /> Figure 5 provides a simplification of the key PM peak hour trip numbers with totals
<br /> shown.

<br /> Though the 2000 Proposed Action with employment of 32,000 is shown in Table 11, for
<br /> the purpose of analysis 33,500 was used.
