1.0 - Background on the Government’s Requirement

The Bureau of Land Management (BLM) Arcata Field Office requires roads-related construction services to replace deteriorated culverts along Prosper Ridge Road in the King Range National Conservation Area (Map 1). The project will install new culverts and upgrade associated surface drainage conditions along approximately one mile of rural dirt and aggregate-surface road in Humboldt County near the community of Petrolia. The road provides access to both public and private lands. Specific actions include culvert replacements, rolling dip construction, aggregate base installation, road reshaping, and rock armoring of vulnerable fill slopes. The contractor will have to supply culverts, rock and water for compaction purposes at each of the treatment sites. The government will provide culvert pipe for one of the sites as detailed below. The work will be in a relatively remote setting with poor to nonexistent cell phone coverage.

2.0 - General Scope of Work

Services include the removal and installation of culverts at three sites along Prosper Ridge Road. The site locations are shown on the map in Figure 1 and the table below lists the general scope of work entailed for each site. Culvert replacement sites will be accompanied by installation of rolling dips, critical dips and rock armoring on the approaches. Specifications for rolling dips and critical dips are provided in Appendix A and contractor will be required to adhere to these in order to provide all season vehicle passage. Prior to the start of work, the BLM will stake and/or flag individual treatment sites.

Required Treatment Sites:

Install 54” culvert on new alignment, Install rock armor along fillslope and at inlet, Install one rock-armored rolling dip, Install and compact 3” class II base rock 40’x20’

Replace with 36” culvert, Install rock armor along fillslope and at inlet, Install one rock-armored rolling dip, Install and compact 3” class II base rock 60’x20’

Replace with 24”x33’ culvert provided by government Install two rock-armored rolling dips, Install one rock-armored critical dip, Install and compact 3” class II base rock 70’x 20’ though crossing

Additive Items:

Depending on funding availability, two additional treatments will be performed as defined below. The possible locations are also shown on Figure 1:

Additive Item A – Add Rolling Dip (cost per site)

· Install additional rocked, rolling dip along the road. Rolling dip installation shall be consistent with specifications in Appendix A. Rock shall consist of 3” ballast rock placed through the axis of the dip and then surfaced with Class II base or suitable substitute along the entire disturbed length.

· Cost for Additive Item A shall be for a single rolling dip, added at any location along the road. Two potential sites are shown in the attached map. Specific locations along Prosper Ridge Road will be identified by the COR depending on the quantity awarded and funding availability.

Additive Item B – Enhance Outslope along 125-feet of Road

· Enhance outslope along 125 feet at the point indicated in attached map adjacent to site #1. Contractor will make efforts to salvage existing rock on the road tread and apply additional 3” subbase to achieve a minimum of 6” depth. Treated segment will then be surfaced with a minimum of 3” Class II base or equivalent.

General Specifications:

· New culverts shall be Aluminized, Type 2 corrugated metal pipe for all culvert sites. Culverts 42" or smaller shall be 12 gauge aluminized corrugated metal pipe. Culverts 48" and larger shall be 10 gauge aluminized corrugated metal pipe.

· Culvert coupling bands shall be made of the same material as the culvert.

· Culverts shall be set into prepared native material free of visible organic debris and rock particles >3”. Compaction shall conform to requitements in Appendix A.

· Contractor shall provide sufficient water to achieve compaction at all treatment sites.

· Ballast rock and Class II base rock shall be angular, crushed particles. Substitutions may be proposed for road base materials to meet the Class II base rock objective of providing a durable all-season running surface.

· Ballast rock shall be 3” max and shall be placed through the axis of the rolling dip / critical dip and then surfaced with Class II base or suitable substitute along the entire disturbed length.

· Rolling Dip/Critical Dip: Assume a 20-foot wide, 80-foot long, 3-inch thick course of Class II base, and one full dump truck load (8yards or x-tons) of 3” ballast rock placed in the center. Install in accordance with the standard typical drawings (Appendix A).

Local Quarries for rock material supplies:

· Billy Eddars in Honeydew, California

· Bear Butte Rock Quarry in Miranda, California

Place of Performance:

Work will be performed along Prosper Ridge Road, located approximately 6 miles SW of the community of Petrolia, California in Humboldt County. One map is provided showing the treatment locations.

For general orientation purposes, Site # 1 is located at the following coordinates:

Latitude: 40.27369 Longitude: -124.34514

Period of Performance:

The period of performance shall be 60 days, commencing at the time of award and completed no later than October 31, 2024.

3.0 - Overall Objective(s) The objectives of this work are:

(1) Replace deteriorated culverts along Prosper Ridge Road to maintain road-stream crossing functions; and

(2) Install rocked, rolling dips on relevant road sections to minimize road surface erosion, disperse runoff and provide for safe vehicle passage conditions that includes trailers and logging trucks.
