Metropolitan Planning Areas
(INDOT Greenfield District)

Important Boundaries

There are several important boundaries that define Metropolitan Planning Organizations (MPOs).

Urbanized Area (UA) - This is the area defined by the US Census that is used to determine that amount of funds received by each MPO based on a per capita calculation.

Metropolitan Planning Area (MPA) - This is the area defined by the MPO and approved by its Policy Board where analysis is conducted to develop a long-range plans and related activities to support its overall "Transportation System" including:
  1. local, county, and state managed roads, corridors, and intersections
  2. rural, urban, and regional transit and associated amenities
  3. local, county, and state bicycle and pedestrian paths, trails, and bikeways and associated amenities
  4. rail and other freight transportation routes, methods, and amenities
  5. ADA & Title VI related transportation access concerns and improvements
  6. impacts of land use, economic development, and redevelopment activities 
Adjusted Urbanized Area (A-UA) - This is an area where two (2) or more MPOs share boundaries and enter inter an agreement to provide services (often retention of services) to a boundary area or municipality that has officially shifted into or out of a given urbanized area per the Decennial Census and per definitions provided by the US Census Bureau.  The agreement generally includes the percentage of per capita funds that are also shifted to provide those services.

Airshed - Some MPOs and other areas within a state may be affected by Airsheds as defined by the EPA that might affect the process by which FHWA Funds, whether programmed by an MPO or INDOT, are obligated.

The link to the ESRI Web Application provides the Airsheds, MPAs, and Approved UA Boundaries (UA or A-UA).

IMPORTANT
  • This resource is intended to provide guidance to INDOT regarding projects as they are programmed.  
  • All projects using FHWA or FTA Funding that are located or will be used with in an MPA must be included the respective TIP of that MPO.  
  • If the project adds capacity to the transportation system within an airshed, the process to initially include, amend, or modify into an MPO TIP will take significantly more time.  
  • Please contact the respective MPO to identify the required processes.
