These are final design drawings for the East Boulder Ditch Fish Passage Design project, prepared by OneFish Engineering, LLC for the City of Boulder's Department of Open Space and Mountain Parks. The comprehensive set of engineering drawings details a fish passage improvement project along South Boulder Creek, involving the construction of a new 470-foot-long 40"x31" aluminized steel pipe arch, a new headgate structure, a diversion structure with removable flashboards, a measurement weir, a gauging station, and various stream restoration elements. The project includes regrading the stream profile, creating constructed riffles, installing rock vanes, implementing toe wood bank protection, and restoring the surrounding landscape.

The drawings specify technical details for stream reconstruction, including a riffle slope of 2.5%, pool depths of 1'6" to 2', and precise elevations ranging from approximately 5284' to 5296'. The design incorporates environmental considerations such as habitat creation, bank stabilization, and erosion control. Specific elements include buried riprap, coir matting, soil restoration, and strategic placement of habitat boulders. The project aims to improve fish passage, stream functionality, and ecological conditions while maintaining the existing water diversion infrastructure. The detailed engineering drawings provide a comprehensive blueprint for contractors, covering everything from structural specifications to materials gradation and installation techniques.
