FINANCIAL ACCOUNTABILITY PROCESS FOR FHWA & FTA PLANNING FUNDS
3
FTA 5305d (Metropolitan Planning Program (MPP)) funds are apportioned to States by a statutory
formula that is based on the most recent decennial Census data available, and the State’s UZA
population as compared to the UZA population of all States. These funds, in turn, are sub-allocated by
states to MPOs by a formula (developed by the State in cooperation with the MPOs and approved by
FTA) that considers each population, regional planning needs, and a minimum distribution.
For Iowa MPOs, the agreed upon formula is that FTA 5305d funds are distributed one-
third equally among all MPOs, one-third based on each MPO’s share of the total
statewide urbanized area population from the most recent decennial census, and one-
third based on each MPO’s share of the total statewide urbanized area population from
the prior decennial census.
FTA 5305e (State Planning and Research Program (SPRP) funds are apportioned to states under a
formula that includes each state’s urbanized area population in proportion to the total urbanized area
population for the nation, as well as other factors. Additionally, FTA 5311 funds are apportioned to
States based on a formula that includes land area, population, revenue vehicle miles, and low-income
individuals in rural areas. A portion of the state’s FTA 5311 funds is combined with the 5305e funds and,
in turn, are sub-allocated by the state to regional planning affiliations (RPA) by a formula that considers
a minimum distribution, population, and regional planning needs.
For Iowa RPAs, the agreed upon formula is that the combined FTA 5305e and 5311
funds are distributed one-half equally among all RPAs, one-quarter based on each RPA’s
share of the total statewide non-urbanized population from the most recent decennial
census, and one-quarter based on the ratio of the number of counties in each RPA out
of the statewide total counties.
FHWA State Planning and Research (SPR) funds are provided by a 2% set aside of the sums apportioned
to the State’s national highway performance program, surface transportation block grant program,
highway safety improvement program, congestion mitigation and air quality improvement program, and
national highway freight program.
For Iowa RPAs, the agreed upon formula is that FHWA SPR funds are distributed on a 1:1
match of each RPA’s FTA 5305d/5311 funding allocation, after such is determined.
The distribution formulas for these funds are historically revisited after each Census to ensure that the
new Census population figures are being used and that any new metropolitan or regional planning
organizations are a part of the calculation. Changes to, or reaffirmation of, the distribution formulas
must be done in cooperation with the metropolitan and regional planning agencies and approved by the
FHWA and FTA.
It is the Iowa DOT’s responsibility to ensure the expenditures of these federal planning funds are used in
accordance with all applicable federal requirements and are used to conduct transportation planning
