The CIRTPA’s transportation system improvements are funded through a combination of federal, state, and local funds. CIRTPA member governments have access to similar types of federal, state, and local funding. The CIRTPA primarily works with the administration of the Surface Transportation Program (STP) funds. CIRTPA sub-allocates the amount of STP funds to each CIRTPA member government using a modified version of the formula used by the Iowa Department of Transportation to distribute STP funds to regional planning affiliations.
Other federal funds include the Surface Transportation Program | Highway Bridge Program, which is distributed to the CIRTPA Counties by the state. Local funds consist of property taxes, Secondary Road Fund (SRF) , and Farm-to-Market funds (FTM). The SRF and FTM funds come out of the state’s Road Use Tax fund.
