Doing Business With the Forest Preserve District

While Forest Preserve District employees perform land and facilities' maintenance, we often employ contractors for large-scale construction or restoration projects.

The District purchases required goods and services in conformance with Illinois state law, the DuPage County Forest Preserve Purchasing Ordinance, related resolutions of the Board of Commissioners and administrative policies. The District makes requirements for purchases under $20,000 in accordance with established procedures for small-dollar purchases and informal quotations. For purchases over $20,000, it advertises formal bid announcements in local newspapers and also lists them on this page. 

The District's Board of Commissioners reserves the right to reject any or all bids and to waive technicalities. 

Please see the District's Purchasing Policy (PDF).
