I found this story courtesy of the Smart Growth Network. It describes a bill that has been authored by Energy and Commerce Chairman, Congressman Henry Waxman, and the Subcommittee Chairman of the Energy and Enviornment Committee, Congressman Ed Markley. The bill would, according to the story, required that "ll states, assisted by U.S. EPA, would have three years to assess their transportation and land use, and set 10- and 20-year targets for related greenhouse gas emission cuts both throughout a state and in any metro area of at least 200,000 residents, while EPA, working with the Department of Transportation, would create a competitive grant program to help finance projects designed to meet the reduction targets." It would also encourage the expansion of public transportation systems and reexamine land use planning.
The federal government, it appears, is getting more involved in land use and planning efforts.
