Hagg Lake Perimeter Roads

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 was completed Nov. 30, 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. The work will also mitigate road damage from an active slide south of Sain Creek Road.

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.

Cost of these projects is estimated at $20.3 million. The Federal Lands Access Program (FLAP) is funding $9.8 million. The remaining $10.5 million cost is shared between the Road Fund (gas taxes) and Washington County Department of Support Services.

The total project cost includes the estimated cost of design and construction and is subject to change.
