NW 185 TH AVE PROJECT FOCUS GROUP MEETING #1 Transportation Plan - - PowerPoint PPT Presentation

NW 185TH 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 185th 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 185th Ave project.

• The NW 185th 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

185th 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/185th Ave intersection capacity

Project Requirements

• The project elements and improvements are defined by various local

and regional plans and provisions: – Transportation Plan, – Community plans – Rural/Natural Resource Plan – Community Development Code – City comprehensive plans – And more…

Project Requirements

– Street Classification: Arterial (streets that link major commercial, residential, industrial and institutional areas) – Design speed: 45 mph – Proposed number of lanes: 5 – Lane widths: 12 feet (travel); 14 feet (center turn lane) – Proposed right-of-way width: 90-98 feet – Sidewalks: 5 feet (typical) – both sides – Bike lanes: 6 feet (typical) – on street, both sides – Traffic Signals: As warranted (needs to meet criteria) – Landscaping: yes – Illumination: yes – Transit (Tri-Met): yes – Bike Route: yes – Truck Route: no – Project Budget: $5.1 Million

Existing Conditions

• Lane Configurations:

– 3 lane roadway – see roadway section in binder – Bike lanes and sidewalks are not continuous along project

• Right of Way:

– Existing right of way varies from 95 to 98 feet

• Natural Features:

– Bethany Lake Park – wetlands and natural resource area

Traffic

• Existing Conditions
• Forecasts
• Traffic Signal Warrant Analysis

Planned Improvements

• Description of Project Limits

– 185th: Westview HS & Rock Creek Elementary to West Union – West Union Improvements – 185th: Improvements at Springville Rd.

Planned Improvements

• Design Considerations:

– Street trees – Storm water system improvements – Safety improvements – ADA improvements – Culvert extensions at Bethany Creek – Regional water quality facility at Bethany Creek – Continuous bike lanes and sidewalks – Continuous street lighting

Planned Improvements

• Design Considerations:

– NW Adrian St.

• Improve sight distance

– NW Tamarack

• Maintain center turn lane

– West Union Intersection

• Adding northbound right turn lane on 185th
• Combining westbound left turn lanes on West Union
• Continuing 2 through lanes eastbound on West Union
• Providing bicycle lanes on all approaches

Planned Improvements

• Design Considerations:

– Springville Rd Intersection

• Adding northbound travel lane on 185th between Chemeketa

Ln and Springville Rd.

• Traffic control remains as is
• Typical 5-lane Section
