Design Standards Manual
The City of Happy Valley’s Engineering Design Manual has been developed to provide a uniform set of standards and procedures to assist the City and private consulting engineers in coordinating, designing and constructing public improvement projects. These standards apply to all improvements within the existing and proposed public right-of-way and easements, to all improvements intended for maintenance by the City, and to all other improvements for which the Municipal City Code requires the approval of the City Engineer. Standards for site grading, erosion control, pedestrian and bike facilities, parking lots, and driveway construction on private property are also contained in this manual and referenced in the City Code. All files are PDF files. If you need AutoCAD files, please contact Karleen Aichele with your specific detail request.
