Engineering Design and Development Standards (EDDS)

Designing and Building Olympia's Vision

The EDDS are the standards that govern new constructionThe Engineering Design and Development Standards (EDDS) are the technical standards used by the City and private developers to design and construct drinking water, reclaimed water, sewer, transportation, stormwater, and solid waste collection systems. The City has a process for requesting a deviation from these standards. Here is the Deviation form.

The EDDS are usually updated annually* after a public hearing and upon City Council approval. The 2018 EDDS update was adopted by City Council and became effective January 23, 2019. The City's Code Publishing site hosts the current EDDS, as well as previous versions of the EDDS that may apply to some vested private development projects.

*In 2019 there were no updates to the EDDS.
