About this file
This document is a set of engineering drawings and specifications for the Buckhorn Road Emergency Forest Road Repair project located in Los Padres National Forest, Santa Barbara County, California, within the USDA Forest Service Pacific Southwest Region (R5), Mt. Pinos Ranger District. The project involves repairing erosion-damaged sections of road at two milepost locations (MP 1.4 and MP 3.9) that have experienced stream scour and embankment failure. At MP 1.4, work includes cleaning and stabilizing a low-water crossing with Class 3 grouted riprap over nonwoven geotextile, capped with aggregate and asphalt edge treatment. At MP 3.9, the more extensive repair involves constructing a 4.5-foot-high precast modular block (PMB) gravity wall system with 150 feet of wall length to stabilize streambank erosion, including base course preparation, wall installation with specified block configurations, embankment finishing with 2:1 slopes, and shoulder backing installation.
Additional work requirements include demolition and reconstruction of existing barbed wire fences, installation of erosion control measures such as erosion control matting, silt fence, straw wattles, and check dams, temporary access road construction, excavation completion in dry conditions with approved dewatering plans, and site cleanup and restoration with seeding of disturbed areas. All work must comply with Forest Service Standard Specifications for Construction of Roads and Bridges on Federal Highway Projects (FP-14) and Forest Service Supplemental Specifications (FSSS), with contractor responsibility for obtaining permits, traffic control planning, work scheduling, equipment cleaning, and quality control inspections. Materials may be site-generated if conforming to specifications and approved by the Forest Service, and excess excavation material must be removed or stockpiled offsite. The project includes detailed engineering plans showing site control points, plan views, cross-sections, wall profiles, and erosion control placement details across 19 drawing sheets prepared by the Forest Service in June 2025.

The repair should consist of a 4½-foot-high (exposed wall height) PMB gravity wall system, with the base of the bottom block course embedded at least 3 feet at the front face to mitigate the effects of scour; based on our analysis, two 60-inch-long blocks with 9⅜-inch setbacks, two 41-inch-long blocks with 1⅝-inch setbacks, and a 28-inch-long top block with a 1⅝-inch setback (all measuring 18 inches high) will be needed for stability.
• Our analysis is based on Redi-Rock® style blocks; alternative PMB styles and manufacturers may be appropriate, but changes in the block geometry may require an alternative design.
• The PMB gravity wall should be placed on undisturbed medium dense/stiff or better subgrade soils.
The exposed subgrade should be proofrolled in dry weather or probed in wet weather to evaluate areas of soft, loose, organic or otherwise unsuitable subgrade materials, and to evaluate whether subgrade mitigations are needed.
• We expect that the on-site material should be suitable for use as PMB gravity wall backfill. Imported backfill, if required, should meet the gradation specifications for Select Granular Backfill.
• Regardless of if on-site material or import are used, PMB gravity wall backfill should be moisture-conditioned to within 2 percent of optimum moisture content, and placed in uniform lifts of suitable thickness for the compaction equipment. Backfill should be compacted to a minimum of 95 percent of the maximum dry density according to AASHTO T-180.
• The wall should bear on at least 6 inches of base course aggregate (meeting gradation designation C in FHWA FP-14 Table 703-2) compacted to 95 percent of the maximum dry density as determined by AASHTO Test Method T-180. The base course aggregate pad should extend a minimum of 6 inches beyond all edges of the base block.
• The fill slope above the wall should be inclined no steeper than 2H:1V.
