Engineering Design and Development Standards

The Engineering Design and Development Standards (EDDS) are a ordinance adopted by City Council that sets the requirements for civil engineering infrastructure. The EDDS is comprised of both written text and standard details that specify how infrastructure is constructed. These improvements include streets, driveways, sidewalks, curbs, street lighting, street trees, water, sewer, storm drainage, and solid waste.
