Executive Summary:
Sonoma County Public Infrastructure (SPI) is requesting Board award of a construction contract to Pat Nelson Construction, Inc., in the amount of $543,210, authorize a 10% contingency of $54,321, and adoption of the project plans and specifications. The project will stabilize an existing landslide on County-owned real property along Eagle Nest Lane in Guerneville through installation of engineered ground support, shotcrete slope protection, drainage improvements, erosion control and site restoration to protect the adjacent roadway and improve long term slope stability.
Discussion:
The Eagle Nest Slide Repair Project is intended to address an existing landslide and improve the stability of the affected slope and adjacent roadway area. The existing slope has experienced movement and erosion that require stabilization measures to protect the roadway and mitigate impacts to the surrounding area. To address these conditions, the Department of Public Infrastructure initiated the Eagle Nest Slide Repair Project.
The project was developed to best stabilize the affected slope through the installation of engineered ground support and slope protection measures. The work includes installation of rock dowels and related ground support, shotcrete slope protection, drainage improvements, erosion control measures, and restoration of disturbed areas.
An invitation to bid for the project was posted through the County’s competitive procurement system. Bids were due September 29, 2026, and three bids were received.
The submitted bids were as follows:
1. Pat Nelson Construction, Inc. - $543,210
2. Rock Supremacy LLC - $658,690
3. Argonaut Constructors - $1,040,025
Pat Nelson Construction, Inc. was determined to be the lowest responsive and responsible bidder and County staff is recommending the Board award the contract to Pat Nelson Construction, Inc. Construction is anticipated to start in late November 2026 and be completed by the end of January 2027.
