The Act requires the preparation and adoption of a countywide stormwater management plan. On February 15, 2007, the District's Board of Commissioners adopted the Cook County Stormwater Management Plan (CCSMP) by ordinance. The CCSMP is not a regulatory ordinance and does not set forth any rules, regulations, or standards to which a municipality will be held to or be required to enforce. The CCSMP is a high level organizational plan wherein the overall framework for the countywide program is established and which the District was required per the Act to adopt as a first step in establishing the District's countywide stormwater management program.

The CCSMP was amended on July 10, 2014 to be consistent with P.A. 98-0652, which amends the District’s statutory authority to allow for acquisition of flood-prone properties and to plan, implement, finance, and operate local stormwater management projects.
