Brownfields Conference E&EM doctoral candidate Jerry Sherk
and E&EM professor Jonathan Deason made presentations at the national
Brownfields conference held in the Adams Mark Hotel in Dallas, Texas during
the period December 6-8, 1999. The presentations
were made during the conference session
on “Greening Brownfields: Protecting Greenspace and Cultivating Quality
of Life,” Chaired by the Honorable Lee R. Clancey, Mayor of Cedar Rapids,
Iowa and co-Chair of the U.S. Conference of Mayors. This session,
which proved to be a popular one with the conference’s 3,000 attendees,
included discussions on solutions to urban sprawl, greenspace protection,
and financing of non-economic uses in brownfields redevelopment.
The GW presentations addressed the interim
results yielded by the EPA-sponsored research project on brownfields redevelopment
that is the subject of Jerry’s doctoral dissertation research. While
the project has four major thrusts, most attendees were interested in the
brownfields/greenfields trade-off ratios that are being derived in the
research. These ratios indicated the degree to which the redevelopment
of urban brownfield sites reduces developmental pressures on undisturbed,
of “greenfield” sites.

While the results presented were preliminary
in nature, study results to date indicate that brownfield/greenfield trade-off
ratios for industrial and manufacturing facilities raged from 1:0.64 to
1:3.28, with a mean of 1:1.60. For mixed industrial, manufacturing
and commercial developments, the ratios ranged from 1:2.87 to 1:60.52,
with a mean of 1:29.67. For residential and commercial developments
the rations ranged from 1:12.21 to 1:35.7, with a mean of 1:21.54.
These results were characterized as very
preliminary estimates of the magnitude of reduced developmental pressures
on previously undeveloped areas resulting from increased redevelopment
of brownfield areas because a significant portion of the work remains to
be performed.
In addition to these key ratios, the researchers
also explained that the research also is drawing important insights into
the existence of federal policies that pose obstacles to brownfields redevelopment
efforts, as well as the identification and evaluation of options to remove
or reduce the effects of such obstacles. The research also is uncovering
ways in which innovative land use policies and actions, particularly at
the state and municipal levels, can enhance brownfields redevelopment efforts.
Deason and Sherk hope to have their work wrapped up and presented to EPA in a final report by the end of this summer. |
