Washington County Council Creek Regional Trail RFFA Grant

Major Project Tasks and Deliverables

Project Area

The Project Area includes the Portland & Western (PNWR) railroad right-of-way (ROW) between Douglas Street in Forest Grove and Dennis Avenue in Hillsboro (northern spur, north of Tualatin Valley Highway).

Analysis will extend east and west to the Hillsboro Regional Center (specifically, the Mark O. Hatfield Government Center Light Rail Station) and Forest Grove Town Center (e.g. Pacific University and downtown Forest Grove). The centers are major destinations for Council Creek Regional Trail potential users and for travelers in the Tualatin Valley Highway corridor.

Major Project Tasks and Deliverables

Task 1. Data Collection

Building from the adopted Master Plan Framework collect and prepare information needed to develop and evaluate the design alternatives and understand potential implications, including planning level cost estimates to address significant issues.

Task 1.1 Corridor Survey and Mapping

Surveys of railroad rights of way (ROW) and topography to collect data relevant to developing design alternatives including property considerations (e.g. fences, accessory structures, etc.), wetlands/flood plains, and all utilities both parallel and crossing that could pose cost risks.

Task 1.2 Bridge and Railroad Trestles Report

Conduct and document structural assessment in report. Consider use of existing bridge and railroad trestles for trail and/or transit use, documenting potential and limitations of both.

Task 1.3 Geotechnical Report

Catalog areas of concern with known geotechnical issues along the corridor based on research and review of existing geotechnical documents and studies.

Task 1.4 Hazardous materials corridor report

Washington County staff

Task 3 Finalize Trail Cross-Sectional Plans Along Entire Corridor Alignment

The primary objective of this task is to determine the preferred cross-section and placement of the trail within the rail corridor ROW. In order to achieve that outcome, this task also includes several elements:

development of performance measures and design criteria, development of alternatives, alternatives analysis, selection of a preferred alternative and development of a corridor plan delivery and implementation strategy.

Task 3.1 Performance Measures and Design Criteria

Identify systemwide outcomes, desired corridor functions and uniform design criteria. This task will involve engaging the public and coordinating with partners to confirm and refine corridor-wide goals, vision and clearly define the needs to guide project development and prioritization. Metro’s “Designing Livable Streets and Trails Guide” should be considered and referenced.

Task 3.2 Preliminary Design Plans

Develop draft corridor plan view with cross-sections for up to three alternatives:

1. Rail-to-trail

This alternative assumes the entire corridor would be dedicated to trail use only. This alternative would not preclude use of the existing railbed for trail use, nor would it require the trail alignment to reserve right-of-way for transit use. Specific trail alignment could make use of entire right-of-way.

2. Transit-with-trail

This alternative assumes a portion of the right-of-way would be preserved for potential future transit use. A determination would need to be made for how much right-of-way should be reserved for transit and the trail would likely be pushed to either the north or south side of the ROW. The CCRT Master Plan indicated that a 16-foot trail section (10-12 foot for the multiuse trail plus two-foot shoulders on either side) would allow for both single track and dual track light-rail line, including room for a station stop. However, a wider trail facility may be considered to accommodate micromobility devices (e.g. scooters, e-bikes and other potential devices), including motorized micromobility devices with a significant speed differential relative to walking.

3. A phased construction hybrid design

This alternative assumes a portion of the right-of-way would be preserved for potential future transit use, however, it takes advantage of the existing railroad trestle and potentially other infrastructure until such time as transit is provided in the corridor. As in option 2, the trail would likely be pushed to either of the north or south side of the ROW, but would transition back to the existing rail placement at the trestle over Dairy Creek (and any other areas, as needed).

Consideration of transit accounts for dedicated right-of-way for transit only. None of the alternatives include transit mode or operational analysis.

Task 3.3 Alternatives Analysis

Evaluate draft cross-section alternatives by segment throughout the entire corridor. Analysis to be informed by concurrent TV Highway transit analysis. Evaluation based on data collected in Task 1 and performance measures and design evaluation criteria identified in Task 3.1 and will include planning-level cost estimates.

Task 3.4 Traffic and Intersection Treatment Alternatives Analysis

Report will include forecasting trail user volumes. Prototype, and some specific, crossings shall be analyzed and typical treatments recommended. Prototype crossings could include:

• State highway (OR 47)

• Arterial/collector intersections

• Driveways

Task 3.5 Preferred Alternative

Identify a project preferred alternative based on the Alternatives Analysis and public and agency comment.

Task 3.6 Corridor Plan Delivery and Implementation Strategy

Identify and evaluate potential strategies for financing, phasing rail to trail and transit with trail, permitting, construction, ownership and maintenance.
