New
Approaches for Stormwater Management
Public Presentation and Workshop by Ken Potter,
University of Wisconsin
October 4, 2002
Urban growth has
often been associated with negative impacts on water resources. As an
example, storm-water discharges can introduce large flows with high levels
of contaminants to streams, rivers, lakes and ground water systems.
‘Low-impact development’ offers potential as a means to accommodate urban
population growth without sacrificing environmental quality. One promising
strategy is to design and construct impervious and pervious developed areas
so as to maintain natural rates of infiltration and groundwater recharge
from stormwater flows.

A morning presentation by Ken Potter on the following themes will
explain the history of stormwater management, problems that have been
historically associated with past and existing stormwater management
practices, and the development of alternative ecologically-based strategies
for stormwater management.
-
History of
stormwater management
-
Inadequacies of
detention-based stormwater management approaches
-
Ecologic
considerations
-
Tailoring
management practices to local ecologic needs and local expectations
-
Design and
evaluation of various strategies for low-impact land development
-
Infiltration
practices and rain gardens
-
Integrated water
management
Afternoon Workshop -

Powerpoint
An afternoon workshop will offer much
greater depth on these same themes, with emphasis on methods for reliably
estimating the benefits of infiltration practices, particularly rain
gardens, in semi-arid environments. Workshop participants will have an
opportunity to use a computer model that has been developed by Ken and his
group at the University of Wisconsin. Participants will also have time to
visit with Ken.
