Recent Progress
A Cost Risk Assessment (CRA) was completed in late August. The CRA examined numerous risk factors in the project, including among others the potential for environmental/permitting complications and rising materials costs. The goal of a CRA is not only to find cost savings but to indentify area's of the project that can be identified that will lead to the highest cost saving or create the highest risks if left under managed. This report identified the crossing of Wiser Lake and the need to insure that the plans contain as much information as needed to minimize uncertainty as two areas that can be targeted to minimize potential risk as the project moves forward. In that regard we will be administering a test pile project in early 2006 near the Nooksack River in order to be able to obtain better data for the design and construction of structures in this area.
Project design continues to steadily move ahead, focusing now on structures and finalizing the proposed alignment and associated elements. In response to comments received during the public Open House held early last spring, a fifth roundabout has been added to the project at the intersection of River Road. After conversations between WSDOT and the City of Lynden, the roundabout which had been under consideration at the intersection of Main Street in Lynden will not be added to the project. The intersection will still be widened in conjunction with the rest of the project, but a traditional traffic signal will control traffic flow. Foundation selection for the structures (the five bridges and a retaining wall) continues to evolve, as does the final preferred alternative for the Nooksack River Bridge. The recently-available geotechnical recommendations indicate very poor soils; WSDOT Bridge is now working closely with the Design Office and Pan-Geo to refine the Nooksack Bridge and foundation configuration in order to provide a final design which clear-spans the river while minimizing settlement issues stemming from poor soils.
Another Open House was held in late July for two consecutive nights, with information focused on the R/W appraisal and acquisition process highlighted at the presentation.
Appraisals in the southern half of the project are now underway, and administrative offers (AO’s) are being readied. Representatives of the Real Estate Office have started contacting property owners with property offers on the southern portion of this project. The southern R/W plan was revised somewhat to reflect a shift in alignment at the southern end of the project, between Tenmile Road and King Tut Road. The alignment shift was made in order to avoid impact on a parcel where the Guide Meridian Water Association wells were located. These revisions have been submitted for approval. R/W plans for the northern half of the project were recently approved.
In response to the unexpected increase in the R/W estimate reported earlier this year, $9.8M was shifted from the CN budget to the RW budget in order to fund the anticipated costs of R/W acquisition for the entire corridor. In doing this, the project was split into two phases – Stage 1, which includes PS&E and R/W acquisition for the entire project corridor but limits construction to the 4.5 mile segment between Tenmile Road (MP 6.00) and the south edge of Lynden (MP 10.39), and Stage 2, which encompasses the construction of the remainder of the project, from MP 10.39 to Badger Road at MP 12.54.
