About this file

Written by GovTribe AI · Jul 28, 2026

This file consists of preliminary construction plans for the Gifford Pinchot ERFO Repairs 2022 project, a Federal Highway Administration project in Lewis County, Washington, located on NF-2801 in Gifford Pinchot National Forest. The project involves roadway reconditioning, drainage improvements, excavation, grading, and aggregate work over a 0.75-mile length with design specifications conforming to FP-24 Standard Specifications for Construction of Roads and Bridges on Federal Highway Projects.

The plans include survey control data establishing coordinate system references (Washington South SPCS NAD83 2011) with field work conducted in June 2023 and final adjustment in June 2023. The project features multiple horizontal and vertical curves with design speeds of 20 MPH, anticipated average daily traffic of less than 400 vehicles in 2024 and 2044. Key construction elements include 18-inch and 24-inch pipe culverts with modified protective aprons, riprap ditches, Type 7A and 7B inlet structures, spillway assemblies with down drains, curve widening up to 5.25 feet, turnouts (10 to 14 feet wide), soil erosion control measures (fiber rolls, silt fence, check dams), and permanent and temporary traffic control signage. Standard drainage details specify Class 2 riprap with geotextile separation at culvert outlets. The plans reference Western Federal Lands Highway Division standards for design approval and include comprehensive erosion and sediment control specifications complying with federal land highway office requirements.
