AASHTO -Somewhat Vague
FHWA - Internal
House - T+I Committee, HR ____
Senate -
100K - Threshold
Grandfathering
200K - Project Selection Authority
1 Million+ Special Funding and Requirements

9. Census Defined Urban Area (UA)
2000 density based, automated process, identified urban clusters (2,500 pop), ignored place boundaries and built from Census Blocks
2010 Census Bureau still deciding process
Investigating use of place of work data via ACS, reviewing land use covers and digital elevation maps and satellite imagery, thinking about using household densities and building from Census Tracts.
Look for criteria for defining urbanized areas and clusters in Spring 2010 in Federal Register
