Promoting uniformity of urban design and construction across Iowa.


Iowa DNR Review

The Iowa DNR Water Supply Engineering Section conducted a review of the 2022 Edition of SUDAS Specifications Divisions 3 and 5. In a letter addressed to SUDAS staff, Iowa DNR stated “at the current time, they are in accordance with the design standards of this Department and will be filed accordingly.” Click here for a copy of the letter.

2022 Edition Revisions

Remember, we do not print and mail revision packets anymore. Electronic versions of the 2022 Edition revision packets can be found under Design Manual -> Latest Design Revisions or Specifications Manual -> Latest Specifications Revisions.

Public Works Service Bureau

SUDAS staff has created a Public Works Service Bureau (PWSB). The PWSB provides a resource for public works staff members from cities of all sizes to connect with and learn from others how best to improve work efficiencies, learn new techniques, and maximize available resources.  Our goal is “communicate to innovate!”
