    What are the EDDS?

    The 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 2018 EDDS update was adopted by City Council and became effective January 23, 2019.

    The EDDS are usually updated annually after a public hearing and upon City Council approval. In 2020 there were no updates to the EDDS.
