Work Program

Surveying / Base Mapping

Aerial and terrestrial surveying methods will be used to develop topographic base maps. These maps will include above ground features such as curbs, sidewalks, buildings, light poles, trees and fences. Underground facilities such as wells, utilities and storage tanks will be mapped by using the terrestrial surveying methods as well as using historical as-built records. The right-of-way edges and centerlines, throughout the project corridor, will also be resolved to document their existing locations. The surveyors will recover monuments, such as iron rods and brass disks, in both the center and edge of the roadway, to calculate and map the right-of-way locations.

These different maps will be used by the design engineers for planning and alternatives analysis purposes.

Preliminary Analysis

Working cooperatively with the various stakeholders, such as the Project Advisory Committee, the Project Management Team will develop various alternatives for making the connection between Walker Road and Baseline Road. Analysis of the alternatives will take several items into consideration such as functional classification, design speed curvatures, sight and stopping distance requirements, environmental impacts, and costs.

This project was designated a “Study Area” in the County’s 2020 Transportation Plan update. The Transportation Plan indicates a need for the project and indicated that Alternatives 1 and 2 be among those considered during the project development phase of the project.

Technical Studies

Several technical studies will be prepared during the course of the project. These reports will cover environmental, engineering, and land use topics.

Permits

Even though this is a public improvement project and it is identified in the Transportation Plan of the both Washington County and the City of Beaverton, land use and environmental permits will need to be acquired through local, state, and federal agencies.

Right-of-Way

It is anticipated that some right-of-way will be needed to build this project. The County has a formal right-of-way acquisition process that works with individual property owners whose property is directly impacted by the proposed improvements.

Construction

Construction of the improvements is currently scheduled to begin in May 2008 and conclude in December 2009. Several factors can influence the construction schedule and this is just a preliminary estimate for planning purposes only.
