Iowa Public Works Service Bureau, Phase 2
SUDAS staff received a research grant from the Iowa Highway Research Board for Phase 2 of the Iowa Public Works Service Bureau project. The proposal can be found here. This phase is a 2 year project and will include the first steps in developing the actual service bureau. We envision this Public Works Service Bureau to be an organization that provides public works staff from cities of all sizes across Iowa a direct way to communicate among themselves and other agencies, such as the Iowa DOT. It will also provide a location to input information for a central clearinghouse on any number of topics, which will then be used to provide statewide data to improve decision making and efficiency of operations. The final report of the feasibility study (Phase 1) can be found here.
Seed Change Memo
Due to a ryegrass crop failure last fall in Minnesota, it may be necessary to modify the rural area permanent seed rates on current contracts and other rural seeding applications in 2021. Minnesota is the primary supplier of seed used in Iowa. The Iowa DOT has suggested that for the 2021 construction season, the seed mixture can be modified by reducing the ryegrass to 30 pounds per acre if the fescue rate is increased to 150 pounds per acre.
2021 Edition Revisions
Remember, we do not print and mail revision packets anymore. Electronic versions of the 2021 Edition revision packets can be found under Design Manual -> Latest Design Revisions or Specifications Manual -> Latest Specifications Revisions.
Iowa DNR Review
The Iowa DNR Water Supply Engineering Section conducted a review of the 2021 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.”
