NW 185 TH AVE PROJECT FOCUS GROUP MEETING #1
Transportation Plan History & Background • Washington County has grown considerably in the past 30 years. – From 1980-2000 the population increased 74% – From 1985-1996 the employment increased 103% ������ ��������������������������
Transportation Plan History & Background • To accommodate future growth and transportation needs the County has an adopted Transportation Plan that provides specific information about transportation needs and how they might be met. • The complete Washington County 2020 Transportation Plan is available online: http://www.co.washington.or.us/LUT/Divisions/LongRangePlanning/Publications/transportation-plan.cfm ������ ��������������������������
Transportation Plan History & Background • The Washington County Transportation Plan was first adopted in 1988 by the Board of County Commissioners. • The 1988 Plan was amended periodically to reflect changes in growth patterns and policy changes in planning regulations. • The Plan was updated in 2002 and was based upon forecasts and analysis for the year 2020. ������ ��������������������������
Project History & Background NW 185 th Ave between Westview High School and Springville Road: • 1988 Plan - This section was identified in the Plan as a 3 lane roadway – This was based on 2005 growth and traffic projections. 2002 Plan Update – This section changed to 5 lanes. – This was a result of ongoing planning efforts by PCC – PCC Rock Creek Campus was added to the UGB – Development north of Hwy 26 became a factor ������ ��������������������������
Project History & Background • In 2005 the Washington County Board of County Commissioners approved the Major Streets Transportation Improvement Program (MSTIP 3c), which included the NW 185 th Ave project. The NW 185 th Ave project falls under the MSTIP policy and funding • program. ������ ��������������������������
MSTIP – What it is & How it works • A program that funds road improvement projects to address local and regional transportation issues. • A program that gives residents local control of improvements to their transportation network. • The first three MSTIP programs (1986, 1989 and 1995) were each approved by voters as short-term property tax levies. ������ ��������������������������
MSTIP – What it is & How it works • In 1997 voters approved Measure 50, which made this temporary tax became part of the county’s fixed tax rate. • MSTIP money goes to the county to design and manage projects. • MSTIP money goes back to the private sector on a competitive basis to build projects under the county’s supervision. ������ ��������������������������
MSTIP – Program Development • MSTIP development is a joint effort of Washington County local governments. • Elected officials from each local jurisdiction meet regularly as the Washington County Coordinating Committee (WCCC). • The WCCC meets to address local and regional transportation issues and selects projects for potential funding using MSTIP. • The Board of County Commissioners (BCC) approves the final MSTIP project list and funding amounts are decided annually. ������ ��������������������������
MSTIP – Project Selection • MSTIP eligible projects have to meet certain criteria: • Improve safety • Remove bottlenecks • Be major roadways used by many residents • Rank as high local government priorities • Address multiple transportation demands (cars, trucks, bikes, pedestrian and transit) • Be geographically balanced, providing benefit to residents all around the county ������ ��������������������������
MSTIP Funding & Results • Every year through 2012 the BCC anticipates providing $26 million for county transportation projects. • Since 1986 MSTIP has: – Built 110 projects in Washington County • 67 Centerline Miles • 110 Miles of Sidewalks • 121 Miles of Bike Lanes – By 2012 will have completed $555 million worth of transportation projects ������ ��������������������������
185 th Ave Project Needs • Safety improvement needs: – Continuous bike lanes and sidewalks – Improve roadway drainage system – Continuous street lighting • Traffic Needs: – Reduce congestion due to bottleneck north of Westview High School – Increased number of travel lanes to handle capacity of existing and future traffic – Increase West Union/185 th Ave intersection capacity ������ ��������������������������
