SKAGIT COUNTY COMPREHENSIVE PLAN UPDATE 2016 TRANSPORTATION TECHNICAL APPENDIX SKAGIT COUNTY TRANSPORTATION ELEMENT TECHNICAL APPENDIX The review and proposed revisions to the Transportation Element for the 2016 Skagit County Comprehensive Plan Update are focused on complying with Growth Management Act (GMA) requirements, updating the plan data and policies, and streamlining documents that make up the element. Regarding that final point, the attached 2016 Transportation Element Technical Appendix is proposed to replace the existing Transportation Systems Plan (TSP) and consists of the following: transportation system inventory, land use assumptions, travel forecasts, Level of Service (LOS) Standards, current and future transportation needs, and a transportation financial plan. Many details not required by GMA and not being used by Skagit County are proposed for removal as the Transportation Systems Plan becomes the Transportation Technical Appendix.
