County-State Traffic Engineering Program (C-STEP)
Intent of program
Solve traffic operation and safety problems on primary roads outside incorporated cities
Who is eligible to sponsor?
Any Iowa county
Qualifications for funding
The county must engineer and administer the project. Improvements must involve a primary road outside any corporate limits.
The two types of projects eligible are spot improvements and linear improvements -
- Spot improvements are those limited to single locations. County match is 45 percent of the construction cost (55 percent is state funded).
- Linear improvements are those for which a single spot improvement is inadequate. County match determined by jurisdiction, as follows:
- State retains jurisdiction upon completion of project – county match 70 percent
- County accepts jurisdiction – county match 40 percent
An engineering analysis of the problem area is required.
- The Iowa Traffic Engineering Assistance Program (TEAP) can be used for analysis.
- A county engineer can provide the engineering analysis.
- DOT’s Brown Design Manual can be cited for turning warrants when the request includes turning lanes.
- The Manual for Uniform Traffic Control Devices has warrants for traffic signals.
