• Significantly change to how funds are
distributed:
– Funding is allocated to the Region as Tribal
Shares
– Tribal Shares are determined by the
Relative Need Distribution Factor (RNDF)
– Funds Distributed to Tribes based on
Projects identified in the IRR TIP, derived
from Tribal TIP’s or Tribal Priorities.
IRR FUNDING BREAKOUT
RNDF is a mathematical formula used for
determine Tribal Shares of IRR Program
construction funds based on the following
factors:
50% Cost to Construct
30% Vehicle Miles Traveled (Current ADT)
20% Population
80% of data used in this Formula is derived
from the IRR Inventory
Relative Need Distribution Factor
What IRR System Roads generate IRR
Funding?
Prior to 2005 : Only BIA Roads
After 2005 (25 CFR 170)
• BIA Roads
• Tribal Roads
• County & Township Roads
• State Highways
Relative Need Distribution Factor
IRR Program Funds

– Up to 25% can be used for Road
Maintenance

– Set aside to perform Transportation
Planning activities.
– Distributed as Tribal Shares
IRR Program Funds (cont.)

is insufficient to complete their Highest Priority
Project
- maximum funding per project is $1 million
– OR, for an emergency disaster on any IRR
Transportation Facility
– Competitive selection process

Construction Engineering (Monitoring )
- Funds distributed based on an Approved
Application to Federal Lands Highway (FLH)
IRR Program Funds (cont.)
Alternate
Construction Funding Source
• Public Lands Highway Discretionary
Funds
