Public Participation

The MPO provides a continuous, cooperative, and comprehensive planning process for the area. As part of this process, the MPO solicits public review and comment on the work, projects, and products that it creates and proposes.

The MPO’s public participation process is outlined in the Public Participation Plan. The process aims to provide citizens, stakeholder groups, and other interested parties with reasonable opportunities to be involved in planning processes.

The Passenger Transportation Plan (PTP) process for Iowa’s 9 Metropolitan Planning Organizations (MPOs) and 18 Regional Planning Affiliations (RPAs) is designed to promote joint, coordinated passenger transportation planning programs that further the development of the local and regional public transportation systems. Public transportation systems in Iowa include 35 public transit systems plus a wide array of human service and private transportation providers.

Public comment period is now open through April 1, 2023.

Public asked to help decide which local transportation projects to fund

Residents of Greater Des Moines are invited to share their opinions on which local transportation projects they would like to see receive funding from the Des Moines Area Metropolitan Planning Organization (MPO). 

Nineteen projects are under consideration, ranging from roadways, bridges and transit buses to trails, safe routes to school and on-street facilities. Nearly $39 million has been requested from the Surface Transportation Block Grant Program, which will have approximately $16 million in available funding. The program is funded by the U.S. Department of Transportation and administered by the MPO.  

The public can find project descriptions and an interactive map of the 19 projects online on this Public Input Map and leave comments on the site now through Wednesday, March 8.  

The MPO also scores the projects on how well they help meet the regional performance measures established in Mobilizing Tomorrow, the region’s recently updated long-range transportation plan ( The scores and public comments will be presented to a funding subcommittee of local officials, who will make a funding recommendation. The recommendation will be presented to the MPO Policy Committee in April for review and again in May for final approval. Once awarded, the grants will be allocated in federal fiscal year 2027.  

For more information on the projects, please call or email MPO staff at 515-334-0075 or
