The intent and purpose of this Final Environmental Impact Statement is to satisfy the
procedural requirements of the State Environmental Policy Act (RCW 43.21c) and City
Ordinance 114057. This document is not an authorization for an action, nor does it
constitute a decision or a recommendation for an action; in its final form it will
accompany the final decision on the proposal.

Appendix F Economic Impact Analysis
Updated Port and Non-Port Truck Impacts
Pro Forma Advisors completed a study on the potential impacts of the proposed new SoDo
arena in July, 2013. Subsequent to this date, the transportation analysis in the FEIS was
updated to integrate additional variables and to modify initial assumptions. The revisions
included changes to transit mode split percentages, parallel route reallocations due to possible
reduced capacity from forecasted increases in train activity and related street blockages, and
updated parking assumptions. These modifications changed the calculated operation at
intersections throughout the study area and, as a result, Pro Forma Advisors’ Port
transportation activity cost impacts changed.
The updated transportation analysis results increased the previous estimated annual additional
costs resulting from port truck delays and the estimated annual costs associated with non-port
truck delays.
The related port and non-port truck delay cost impacts are summarized below.
Updated Port Truck Cost Impacts
The updated impacts resulting from the modifications to the transportation analysis for port
truck delay costs are summarized in Exhibit ES-16U below. The modifications to the
transportation analysis increased the annual truck trip delay hours from 2,299 hours to 2,408
hours (or $110,370 to $115,584).
The primary reason that the impact on port truck trips delay costs increased was an overall
increase in the estimated delay on corridors and intersections used by port trucks, most
significantly for Alternative 2 Case S2. When multiplied by the estimated port truck trips on
those routes for the different event cases, the revised intersection delay estimates increased
the projected annual port truck delay by 109 hours (from 2,299 to 2,408), and annual cost by
$5,214 (from $110,370 to $115,584).

Updated Non-Port Truck Impacts
The updated impact of non-port truck costs are summarized in Exhibit ES-18U below. The
modifications to the transportation analysis increased the annual truck trips from 185 to 199,
and increased the estimated delay on affected corridors. Correspondingly, the additional
estimated annual costs increased from $38,351 to $66,141.

The reasons for the increased delay cost impact on non-port trucks include the higher number
of projected daily 2030 truck trips, and longer estimated delays on relevant corridors. The total
trucks trips for 2030 increased from 10,572 to 11,396; the non-port truck total (“cordon
entries”) increased from 1,109 to 1,196; and the estimate of affected (4 PM – 6 PM) non-port
truck trips increased from 185 to 199. When applied to the greater expected corridor travel
time delays in the current FEIS Appendix E Table 2-41 (p. 2-252), the higher number of non-port
trucks results in an estimated annual cost increase of $27,790 (from $38,351 to $66,141).
