The City Standard Construction Specifications are patterned after the 2018 ODOT/APWA Oregon Standard Specifications for Construction with modifications to accommodate the issues typical to the urban city environment. Special Provisions are updated on a regular basis and posted on this page when standard specifications need modification.
