.jpg "27th Street Redmond") As part of an upgrade of SW 27th Street from “Local Street” to “Minor Arterial” roadway classification, NW Engineers provided design services for 2.1-mile roadway and sanitary sewer design. The limits of the project are from SW Cascade Ave to SW Canal Street. Creative design included careful selection of a practical and cost-efficient vertical and horizontal alignment. NW Engineers design team carefully analyzed and weighed the advantages and disadvantages of related issues such as elevations, slopes of connecting streets and driveways, depths of existing and proposed utilities, surface drainage patterns, amounts of cut and fill, and proposed retaining wall heights. A study comparing a signalized intersection and roundabout was included.
