About this file
This document is a set of plans and standard drawings prepared by the Oregon Department of Transportation for the US 101 Coos County Stockpile Site Project in Coos County, Oregon. The project involves the installation of 130 linear feet of 18-inch HDPE culvert pipe distributed across three locations: 57 feet at Station 24+25, 45 feet at Station 18+00, and 25 feet at Station 13+44. The scope includes culvert embankment and slope protection at inlet and outlet locations using Class 200 riprap (totaling 35 cubic yards), general excavation for ditches and roadway construction, installation of subgrade geotextile, and 12 inches of aggregate base. The project is located along Highway 101 at Milepost 245.56 in Coos County, Oregon. The plans indicate total excavation of approximately 9,047 cubic yards with embankment of 5,036 cubic yards, with various grade percentages ranging from -3.01% to +10.82% along the project corridor.
The technical drawings include plan and profile views depicting horizontal and vertical alignment with stationing, curve data (including chord lengths, deflection angles, and tangent lengths), slopes designated as 1:4 and 1:2 for cut and fill areas, and minimum 4% longitudinal slope for drainage. The design incorporates 18-inch HDPE culvert pipe meeting Class 200 specifications for riprap protection, with minimum 5-foot depth requirements. Cross-sectional details show the aggregate base construction with subgrade geotextile installation. The project documentation references additional drawing numbers (RD300, RD317, and RD390) for detailed culvert specifications and embankment protection details. The plans were prepared by designer Jered Carpenter and reviewed by Judy Hardin, with CADD technology documentation dated February 2, 2026.
