  3. Planning Framework • WA Growth Management Act • Vision 2040 • King County Countywide Planning Policies • City of Sammamish • Transportation Goals and Polices • Concurrency Management • Public Works Standards • Capital Improvement Plan • Impact Fees • Six-Year Transportation Improvement Program

  4. PSRC /Growth Management Act Key Requirements • Adopted levels of service (LOS) standards • A forecast of traffic for at least 10 years, including land use assumptions used in estimating travel • A pedestrian and bicycle component • A description of any existing and planned transportation demand management (TDM) strategies • An analysis of future funding capability 4

  5. Vision 2040 King County Countywide Planning Policies • Supporting Growth – focusing on serving the region with a transportation system that furthers the Regional Growth Strategy • Mobility– addressing the full range of travel modes necessary to move people and goods efficiently within the region and beyond • System Operations – encompassing the design, maintenance and operation of the transportation system to provide for safety, efficiency, and sustainability 5

  6. Land Use Creates Travel Demand 6

  7. Transportation and KCPP Growth Targets 7

  8. Auto Trips Created by Increase in Sammamish Growth Target • 640 additional housing units create 300 to 640 new PM peak trips • 288 additional jobs create 100 to 400 new PM peak trips • Current housing creates over 16,000 PM peak hour trips • Reducing current residential travel demand 6.5% would result in no increase in auto traffic 8

  9. Existing Transportation Conditions • Majority of travel is automobile oriented • Access to and from Sammamish is significantly impacted by land use and transportation policies of other agencies (Issaquah , Redmond, WSDOT) • Non-motorized travel is limited by lack of connectivity and distance between origins and destinations 9

  10. Walking to Dinner 10

  11. Walking to the Bus 11

  12. Past Transportation Investments • Major investments have been made in arterial improvements • 228th Ave , 244th Ave, and East Lake Sammamish Pkwy • Transit Investments - Park & Ride at 228th Ave SE/IPL Road • Sound Transit Funded • More recent investments have been made in non-motorized projects • 244th Ave, Sahalee Way, SE 20th Street, SE 24th Street 12

  13. Regional Transportation Trends • Travel per capita in Vehicle Miles of Travel (VMT) is decreasing 13

  14. Regional Transportation Trends:Commute Trip Reduction Works 14

  15. Regional Transportation Trends:People are making longer trips by bicycle 15

  16. Regional Transportation Trends:People are literally moving by bicycle 16

  17. Sammamish Transportation Trends • Traffic volumes continue to increase and shift to other routes as demand increases • Transit service at risk due to funding shortfalls • No travel time savings with transit since buses use general purpose lanes • More interest in non-motorized/active transportation • Town Center will support non-motorized travel, trip sharing, and internal capture 17

  18. Transportation Level of Service and Capacity • Level of Service is based upon the volume on arterial streets and intersections and is already multi-modal • The arterial system is near capacity using 2031 growth targets • There is likely adequate capacity to meet LOS standards for 2035 18

  19. Key Policy Considerations • Support Planned Growth – focusing on a transportation system that supports desired growth • Mobility – address the full range of travel modes necessary to move people and goods efficiently within the city and beyond • System Operations –strive to maximize the efficiency of the existing system rather than look to expansion first. Emphasize auto demand reduction and mode shift over auto capacity expansion 19
