Hagg Lake Perimeter Roads

About

Hagg Lake Projects May 2017

Scoggins Valley Road and West Shore Drive make up the perimeter roads around Scoggins Valley Park and Henry Hagg Lake, with widened shoulders for bicyclists and pedestrians. The park is a popular destination in Washington County, experiencing nearly one million visitors annually. The roads around the lake are in need of maintenance due to numerous active landslides, and culverts and a road surface that are reaching the end of their life cycle.

The projects around Hagg Lake will:

  • Stabilize five active landslides.
  • Improve subsurface drainage at the Stepien Road intersection.
  • Replace five failing culverts on non-fish bearing streams.
  • Replace one failing culvert to provide fish passage.
  • Upgrade the guardrail to current standards.
  • Overlay (pave) Scoggins Valley Road and West Shore Drive, including the widened shoulders.

The work around the lake is scheduled to be carried out in three phases to minimize conflicts with organized events at the park and the busy summer season.

Phase 1 will improve the paved section of Scoggins Valley Road between West Shore Drive at the dam and Stepien Road. The work will include two landslide mitigation projects, improvement of subsurface drainage at Stepien Road, two culvert replacements including one fish passage culvert, an asphalt overlay, and guardrail upgrades. Construction of the culvert replacements and landslide mitigations were completed in 2015. The guardrail upgrades and asphalt overlay were completed in 2016.

Phase 2 will stabilize the landslide at Hankins Road and rebuild the failed lane. Construction of the landslide mitigation is scheduled for Sept. 6-Dec. 4, 2017.

Phase 3 will improve the 6 miles of West Shore Drive. The anticipated work will include stabilizing an active landslide north of Scott Hill Road, replacing three culverts on nonfish-bearing streams, overlaying West Shore Drive and upgrading the West Shore Drive guardrail. 

Construction of Phase 3 is planned to begin in spring 2018 with the landslide mitigation and culvert replacements. The asphalt overlay and guardrail upgrades are anticipated to be completed by the fall 2018.

The $11.5 million project is being funded between Road Fund and Washington County's Department of Support Services. In addition, Washington County has been awarded $5.8 million in federal funding through the Federal Lands Access Program (FLAP). The total project cost includes the estimated cost of design and construction and is subject to change.

Update 5/23/17:

Design of the landslide mitigation at Hankins Road is complete. Construction is anticipated to begin this August. West Shore Drive north of Hankins Road will remain open through Labor Day, and then be closed for an extended period of time during construction. A 10-ton weight limit has been placed on this section of road in an attempt to keep one lane open as long as possible.

Design of Phase 3 is nearing completion with construction anticipated to begin in spring 2018.

Update 8/23/16:

Guardrail upgrades and paving work on Scoggins Valley Road is complete and final road striping and hydroseeding will wrap up by end of the week. This completes work planned for Scoggins Valley Road for this year. 

Work on Phase 2 of the Hagg Lake Perimeter Roads project is expected to continue next year with work on West Shore Drive.

Update 8/9/16:

Additional work on guardrail at slides at Milepost 4 and Milepost 7 will extend work on Scoggins Valley Road for two more weeks. Work is now planned to continue through the end of August. Final road striping and hydroseeding will be delayed until after the guardrail work is complete.

Meanwhile, the lane closure on West Shore Drive across Scoggins Dam has been extended one week to Aug. 26. Bureau of Reclamation's seismic testing of Scoggins Dam required the extension.

Update 7/27/16:

Final paving work is wrapping up. Road striping is scheduled for Aug. 10-11. Guardrail upgrades continue through Aug. 12. The overlay paving and guardrail upgrades are the last planned construction activities for Scoggins Valley Road in 2016.

Plans are being developed for work on West Shore Drive. Construction is expected to begin spring 2017 and will include stabilizing multiple landslides, replacing culverts, upgrading guardrails, and overlay paving. The work will be done as a joint effort by Washington County and the Western Federal Lands division of the Federal Highway Administration under the Federal Lands Access Program (FLAP).

Update 6/20/16:

Baker Rock Resources returns to work on Scoggins Valley Road this week. Starting Wednesday, they will be finishing the paving of guardrail flares and preparing the road for the upcoming overlay. Paving of Scoggins Valley Road is expected to start the week of June 27 and continue for two weeks.

Bureau of Reclamation's work on the dam continues, maintaining the existing traffic restrictions.

Update 6/10/16:

Scoggins Valley Road gets a break while the contractor waits out wet weather. The plan is to return the week of June 20 to finish paving around the guardrail upgrades (mostly shoulder work). Roadway paving is now scheduled the week of June 27, pending weather.

Meanwhile, Reclamation's seismic testing of Scoggins Dam will restrict traffic across the dam starting June 13.

Update 5/11/16:

Work continues on Scoggins Valley Road with a culvert replacement on May 16. Guardrail upgrades continue. Paving is scheduled June 10 through June 29, with final road striping and cleanup wrapping up mid- to late July. Expect lane closures and daytime delays.

Meanwhile, Bureau of Reclamation's seismic testing of Scoggins Dam will also impact traffic during June. West Shore Drive across the dam will remain open, but only one-way traffic will be allowed.

Update 5/6/16:

Scoggins Valley Road reopened this afternoon. Road striping will be restored at both recent repair locations - the Milepost 4.7 landslide and the West Shore / Stepien intersection - on Tuesday, May 10, which will complete both of these projects.

Update 5/2/16:

Pihl Excavating is on track to complete work at the intersection of Scoggins Valley Road and West Shore Drive / Stepien Road. The road should reopen to traffic on Friday, May 6.

The next phase of work will be the paving of Scoggins Valley Road and adjacent guardrail upgrades. That work is expected to begin mid-May and continue into July. Baker Rock Resources will be doing this work.

Starting May 31, the Bureau of Reclamation's seismic testing of Scoggins Dam will require closure of the southbound lane of West Shore Drive across the dam. To reach West Shore Drive, follow Scoggins Valley Road around the lake perimeter.

Update 4/20/16:

Construction on Scoggins Valley Road at Milepost 4.6 was completed on April 19 and the road was reopened. Road striping will occur later.
