Local Centerline Mileage
• In January 2011, GDOT Commissioner Vance
Smith sent a letter to all of Georgia’s Elected
Officials
– 159 Counties
– 531 Municipalities
• We requested the they report the total local
public road centerline mileage (Paved or
Unpaved)
• This information is needed to comply with
State and Federal Law
• LMIG funds will be distributed to Local
Governments based on paved and unpaved
centerline miles and population
• TIA also requires an accurate accounting of
centerline miles to calculate funding for each
Regional Commission
• As of May 3rd, we received reports from
– 152 Counties (96%)
– 325 Cities (61%)
• We provide the mileage to Local Grants Office
– If local government reported, we provided that
mileage
– If local government did not report, we provided
our recoded mileage
• Confirm that your local government has
reported its Center Line Mileage to GDOT on
the official Reporting Form
• As a Local Government, you are required
within 90 days to inform GDOT when you
have:
– Acquired / Accepted / Abandoned a road
– State Code 32-4-41 and 32-4-91

Begin Summer 2012
After each decennial census, the Census Bureau identifies and
classifies urban and rural areas.
The Census Bureau identifies urban and rural areas solely for
the purpose of tabulating and presenting statistical data.
1906 - Urban areas of at least 2,500 people
1950 - Urbanized areas of 50,000 or more people
2000
Urban places of at least 2,500 people were identified
outside urbanized areas.
Urban clusters of 2,500 - 49,999 were defined

and Small Urban Areas that

• Expands Census boundary to
define boundaries to better
reflect local conditions.
