Discussion focuses on Iowa's historic hydrology and native ecosystems
(DES MOINES) – The State Historical Society of Iowa’s History for Lunch lecture series continues next week with a discussion about the history of hydrology and native ecosystems in Iowa.
Wayne Petersen will present “Low Impact Development and Utilizing Green Stormwater Infrastructure: A Virtual Tour of Project Sites Throughout Iowa” at noon on Wednesday, March 20, 2013, at the State Historical Society of Iowa’s Centennial Building, 402 Iowa Avenue in Iowa City. The presentation is free and open to the public. Seating is limited. Call 319-335-3911 for more information.
During his presentation, Petersen will focus on the following topics:
Historic hydrology of Iowa and how the sustainable hydrologic cycle worked when the state’s native ecosystems were intact.
Land use changes that have altered the hydrologic cycle and created water quality and flooding problems.
A new paradigm for managing urban runoff in ways that mimic the sustainable historic hydrology.
Practices that help infiltrate runoff from streets, alleys, parking lots and other urban landscapes.
Infiltration-based practices that protect water quality, reduce the volume of runoff and reduce urban stream flows.
Petersen is the Urban Conservation Program Coordinator for the Iowa Department of Agriculture and Land Stewardship, Division of Soil Conservation. He has worked in the field of soil and water conservation for 37 years, including 21 years working on agricultural landscapes.
For the past 16 years, he has worked with urban and urbanizing landscapes – promoting low impact development and the utilization of green infrastructure. These “still new” strategies and practices help reduce the volume of runoff, improve water quality and stabilize stream flows.
Petersen also helps manage a property for the Johnson County Heritage Trust – a land trust that owns eight properties in Johnson County and focuses on the reconstruction of Iowa’s native ecosystems.
Petersen’s presentation is offered in partnership with the Johnson County Heritage Trust. New Pioneer Coop will provide refreshments. The State Historical Society of Iowa is a division of the Iowa Department of Cultural Affairs.
