Milton staff unveils consolidated public works design standards after decade-long update

Public Works Director Madden told the council at a June 8 study session that city staff and consultant engineers have completed a multi-year effort to modernize Milton’s public works design standards, cutting the number of graphical details from 171 to 87 and converting drawings into searchable AutoCAD files.

Madden said the update was intended to bring Milton’s standards into line with current engineering practice and reduce conflicts and contractor confusion. “We started out with 171 standard details … we ended up with 87 details,” Madden said, and added that the city relied on Washington DOT standards where appropriate to reduce liability and keep details current.

The revision program also included coordination with utility and stormwater specialists; Madden said he worked with Ryan Graves of Gray and Osborne and city utility staff (including the new utility director, Patrick) during the graphical redesign. Graves was present for the presentation and Madden said he led the project for the city.

Madden told council staff will complete a final pass through the written verbiage attached to the standards and expects roughly three months of internal work to finalize the text and bring a consolidated document back to council. He said the searchable format will allow staff to make incremental edits going forward rather than the multi-year, wholesale updates done historically.

Council members asked clarifying questions about consulting attribution and the timeline. Council Member Mounts thanked staff for cutting the document in roughly half; Council Member Hall asked who contributed to the work and Madden listed internal specialists in stormwater and electric as well as consultants.

The update is informational at this session and not a decision item. Madden said the city will return with the full, final document after staff completes the verbiage and internal review.

The council moved on after receiving the presentation; no formal action was taken on the standards during the June 8 session.
