About this file
These engineering design plan sheets are from the Washington County Department of Land Use and Transportation for the SW Elwert Road Culvert Replacements Design Package, dated May 2024. The project involves replacing two culverts (Culvert No. 2225 at MP 1.166 and Culvert No. 2226 at MP 1.154) with new precast concrete culverts. The design package includes detailed engineering plans for grading, drainage, structures, paving, guardrail, and roadside development, with specific focus on culvert replacement at two locations along SW Elwert Road in Washington County, Oregon.
The project documents specify technical details for the culvert replacements, including a 192" x 108" culvert with specific construction requirements such as removing existing culverts, constructing new culvert sections, installing guardrails, and managing roadway approaches. The design complies with Oregon Revised Statutes, specifically ensuring no utility infrastructure is placed within one foot of survey monuments. The project elevations are based on Washington County Datum, and the basis of bearings uses the Oregon Coordinate Reference System. The culvert replacement is part of the 2024 infrastructure improvement efforts, with precise engineering specifications for material types, placement, and road restoration.

BASIS OF BEARINGS AND ELEVATIONS:
The design complies with ORS 92.044 (7) in that no utility infrastructure is designed to be within (1) foot of a survey monument location shown on a subdivision or partition plat. No design exceptions nor final field location changes shall be permitted if that change would cause any utility infrastructure to be placed within the prohibited area.
