SECTION 17: PROJECT LISTS - OFF-SITE ROADWAY MITIGATION <br /> Findings: <br /> • The type and scale of projects needed to mitigate Expansion impacts have been identified. <br /> • A list of specific mitigation projects which are required to mitigate impacts on the <br /> Transportation System is contained in the Decision Document, "Mitigation Program and <br /> Improvements", Section VIC, pp. 37-42. <br /> • Many of the roadway projects listed in the Decision Document are represented in <br /> previous studies and documented elsewhere. <br /> • Project designs and details are not generally available for most public capital needs lists <br /> and, therefore, not provided in the Decision Document. Until alignment studies and <br /> preliminary engineering are completed, these projects can only be presented as project <br /> concepts with order-of-magnitude cost estimates. The descriptions define the type of <br /> improvement, its location, dimensions and estimated cost. <br /> • Several non-roadway improvements require additional analysis in order to define specific <br /> locations and/or characteristics. Neighborhood traffic mitigation projects must await <br /> neighborhood analysis, selection of specific projects and design before details are <br /> provided; park-and-ride lots must be located and designed; the High Capacity Transit <br /> "acceleration" study must be defined. The need for these projects is demonstrated by the <br /> analysis contained in the Boeing EIS and the mitigation addresses identified impacts. <br /> Design details will not affect the decision to require these types of improvements as part <br /> of the mitigation. <br /> • Alternative solutions and associated environmental review must be completed for many <br /> of these projects. Project descriptions in these cases, therefore, is conceptual and <br /> necessarily lacks specific detail awaiting required project-level environmental review. <br /> • Planning refinements and design details are deferred to the next phase. The applicant is <br /> not required to await detailed outcomes of these refinements that involve how the <br /> improvement is made, not whether it is made. <br /> • The development of project details through additional engineering may result in changes <br /> in the project or even deletion of the project. The Responsible Official may, as provided <br /> in the Decision Document, redefine the project, shift funding to another project or <br /> projects consistent with SEPA or decide to delete the project (see Mitigation Committee, <br /> Findings and Conclusions). <br /> 29 <br />
