Request for Proposals (RFP) for Professional Engineering Services 2022 - 2023 Storm Damage Repair Projects

The County is seeking a qualified Consulting firm to provide engineering design, geotechnical, and environmental permitting services for a total of five (5) December 2022 through March 2023 storm damage sites that were identified along Bear Creek Road, Eureka Canyon Road, Mountain View Road, and Redwood Lodge Road. Descriptions of the damage in addition to the anticipated repairs for the sites are described below. Hazell Dell Road at PM 2.35 (2022 December) - Heavy rain caused water to run over the roadway and down the embankment. The saturated soils and could not handle the volume of runoff causing a portion of the road embankment to lose stability and fall into the creek. The slipout has been faced with shotcrete to stabilize the remaining travel lane and the proposed project is to construct an MSE wall to restore the roadway embankment. Services needed: Design, Geotech, Permits (Water Board, F&W, Army Corps., Riparian Exception-County Planning) Bear Creek Road at PM 7.41 (2023 March) - Heavy rain caused water to run over the roadway and down the embankment. The saturated soils could not handle the volume of runoff causing the embankment to lose stability and fall down the hillside. The proposed project is to construct a soldier pile wall. Services needed: Design, Geotech, Permits (Water Board, F&W, Army Corps., Riparian Exception-County Planning) Eureka Canyon Road at PM 5.17 (2023 March) - Heavy rain caused water to flow in high volume over the roadway and down the embankment, resulting in a slipout on the West Bound shoulder. The proposed project is to construct rock slope protection and drainage improvements. Services needed: Design, Geotech, Permits (Water Board, F&W, Army Corps., Riparian Exception-County Planning) Hazell Dell Road PM 2.57 (2023 March) - Heavy rain caused water to run over the roadway and down the embankment. The saturated soils could not handle the volume of runoff causing the road embankment to lose stability and fail. The proposed project is to construct rock slope protection or a retaining structure and drainage improvements. Services needed: Design, Geotech, Permits (Water Board, F&W, Army Corps., Riparian Exception-County Planning) Ice Cream Garde PM 1.24 (March 2023) - Heavy rain caused water to run over the roadway, over a log retaining wall, and down the embankment. The saturated soils could not handle the volume of runoff causing the road and retaining wall to lose stability and fail. The proposed project is to construct rock slope protection and drainage improvements. Services needed: Design, Geotech, Permits (Water Board, F&W, Army Corps., Riparian Exception-County Planning) Jamison Creek Road PM 1.09 (March 2023) - Heavy rain caused water to run over the roadway and down the embankment creating a 40 foot long slipout. The saturated soils and failed culvert could not handle the volume of runoff causing the road to lose stability and slump. The proposed project is to construct a soldier pile wall. Services needed: Design, Geotech, Permits (Water Board, F&W, Army Corps., Riparian Exception-County Planning) Spreckels Drive south of Soquel Drive (March 2023) – Heavy rain caused water to run over the roadway and down the embankment. The saturated soils could not handle the volume of runoff causing the road side to lose stability and fail. The proposed project is to construct a soldier pile wall. Services needed: Design, Geotech, Permits (Water Board, F&W, Army Corps., Riparian Exception-County Planning) Upper East Zayante Road PM 1.18 (March 2023) - heavy rains caused water to run over the roadway and down the embankment. The saturated soils and could not handle the volume of runoff causing the road to lose stability and fall into the creek. The proposed project is to construct a soldier pile wall.
