Distribution formula

Local Programs continues to distribute funds based on a formula driven formula developed in coordination with the MPOs and counties, as follows:

• Urbanized areas greater than 200,000 population – Distributed based on 2010 Census data as required.
• Urbanized areas greater than 50,000 but no more than 200,000 – Distributed based on 2010 Census data as required.
• Urban areas greater than 5,000 but no more than 49,999.
• Under 5,000 population – Distributed based on rural lane miles.
• Flexible –
   Distributed based on 75% population/25% total county lane miles
   Local Programs administration costs will be decreased from the initial allocations based on a proportional share of the total allocation for each entity.
