This document is a culvert repair project plan sheet prepared by the Oregon Department of Transportation for Washington County on Highway 217 at mile point 3.34 near Beaverton-Tigard. The project involves rehabilitating an existing 36-inch corrugated metal pipe (CMP) culvert for a total of 175 linear feet, installing an 18-inch polyvinyl chloride (PVC) flared inlet, removing and reinstalling 10 linear feet of 36-inch CMP, installing a 36-inch flared end section, installing Class 50 riprap outlet protection (5 cubic yards), removing and reinstalling 12 linear feet of guard rail, and re-seeding 0.01 acre of disturbed area. The project location is situated in Section 22, Township 01 South, Range 01 West, Willamette Meridian, and includes general construction notes addressing temporary water management, sediment control, site restoration, and full isolation requirements with sandbag barriers for the work area.

The technical specifications detail trench backfill, bedding, pipe zone, and multiple installation requirements for corrugated metal pipe coupling bands, with standardized dimensions and materials in accordance with Oregon Standard Drawings and Specifications effective through May 31, 2025. The plan incorporates safety protocols emphasizing environmental protection and sediment control measures to prevent sediment-laden water from leaving the site during construction and unexpected storm events. All materials and work must comply with current Oregon Standard Specifications, and the contractor bears full responsibility for implementing and maintaining the temporary water management facility until construction is completed and approved. The project includes detailed sandbag barrier calculations for full isolation and dewatering procedures to manage site conditions during construction activities.
