Our History

Soil and water conservation districts (SWCDs) were written into state law in the 1930’s after the devastation of the Dust Bowl – a consequence of drought conditions and farming without conservation. These local units of government were formed across the nation to help citizens conserve soil, water, and other natural resources. They helped create a link between government resources and local landowners to increase the application of conservation on private land.

Polk County officially formed its own soil and water conservation district in 1945. The district is governed by a board of five elected commissioners and appointed assistant commissioners. These individuals make decisions on how federal and state conservation funds should be used across the county. Since it’s formation, the district has expanded their services by providing outreach to the urban community and establishing new partnerships to insure long-term problem solving through the use workshops, trainings, and cost share programs.

Over the past 20 years, Polk SWCD has also taken a lead on watershed based efforts in Central Iowa. By working with local partners and residents to address local issues, the district has taken a part in tackling issues such as bacteria and algae blooms in Big Creek Lake, flooding in Fourmile Creek, stormwater pollution in Easter Lake, and many others. Through grant funding and local partnerships, the district has grown to include a staff of watershed coordinators to better serve Central Iowa.

John Norwood Bio:

Elected to Polk County Soil and Water Conservation District in 2018.

Employment: TBL Ventures, LLC – a business strategy and business operations concern that works across the political spectrum, and public, private and non-profit sectors, to solve complex resource problems in agriculture, business and government.

I have a 20-year professional background that includes work in the agricultural sector both here in Iowa and previously in California and the East Coast.

I have two master’s degrees from Yale University. One is an MBA with an emphasis in public finance. The other is a Master of Environmental Management from the Yale School of Forestry & Environmental Studies (essentially an agriculturally related degree by a fancy name). At Yale, I studied watershed management, soils, and hydrology, and completed a master’s project on financing stream buffers in an urbanizing watershed of the Hudson River. --- John@tblventures.com Visit John's Polk SWCD Facebook Page
