SB 1789
SB 1789 sets statewide riparian buffers to cut erosion and runoff: 50-ft vegetated buffers on public waters (30-ft min) or 16.5-ft cultivated-land option, phased by 2026-27.
Status & key dates
- Bill: SB 1789 — "Riparian Protection and Water Quality Practices Act"
- Primary sponsor: Sen. Laura Ellman; Co-sponsor added: Sen. Graciela Guzmán
- Introduced: February 5, 2025 (filed Feb 6, 2025); co-sponsor added Apr 4, 2025
- Companion: HB 4627
- Enacted: Signed by Governor June 20, 2025
- Effective date: September 1, 2025
Purpose
- Establish statewide minimum riparian buffer and alternative water-quality practices to protect State water resources from erosion and runoff pollution, stabilize soils/shores/banks, and protect or create riparian corridors.
Major provisions
- Buffer requirement (land adjacent to water bodies mapped on Department buffer‑protection maps):
- Public waters: continuous vegetated buffer averaged 50 feet in width, minimum 30 feet; composed of perennial vegetation (no invasive plants or noxious weeds). Measurement from top/crown of bank or edge of normal water level.
- Public drainage systems: buffer minimum to be set consistent with applicable drainage district rules and must not impede future maintenance. Measurement follows drainage authority guidelines.
- Cultivated land alternative: landowners engaged in cultivation adjacent to mapped water bodies may meet requirements by establishing a 16.5‑foot continuous buffer or by implementing approved alternative practices (e.g., retention practices, ponds, NRCS Field Office Technical Guide practices, Department‑ or locally‑approved practices).
- Implementation deadlines:
- Buffers/alternatives for public waters: must be in place by November 1, 2026.
- Buffers/alternatives for public drainage systems: must be in place by November 1, 2027.
- Mapping and local planning:
- Department of Natural Resources to establish and maintain buffer‑protection maps.
- Soil and Water Conservation Districts (SWCDs), in consultation with local water management authorities, must submit summaries of watercourses within their jurisdiction by July 1, 2026.
- Local water management authorities must incorporate SWCD recommendations into comprehensive water management plans by July 1, 2027 (without formal plan amendment if recommendations are distributed to stakeholders).
- Assistance and funding:
- SWCDs to provide planning and technical assistance to landowners.
- Department required to provide funding sufficient to implement the Act; may withhold state funding from local authorities that fail to implement the Act until a corrective action plan is approved.
- Planting standards:
- Seed mixes used to establish buffers must be approved by the Department of Agriculture to prevent invasive species/noxious weeds.
- Enforcement, appeals, and penalties:
- Local water management authorities issue notices and require corrective actions; may pursue administrative enforcement and penalties (which may be forgiven upon satisfactory corrective measures).
- Landowners may appeal Department notifications or penalties; the Director must issue a final administrative decision within 60 days; decisions appealable to Illinois courts under the Administrative Review Law.
- Exemptions:
- Lands enrolled in the federal Conservation Reserve Program (CRP), public/private water access or recreation areas, land covered by road/trail/building/structures, lands regulated by an NPDES permit, lands part of a water‑inundation cropping system, and land temporarily nonvegetated due to authorized construction/maintenance/conservation projects.
Who is affected
- Private and public landowners with property adjacent to water bodies mapped on the Department’s buffer‑protection maps (including State property).
- Local water management authorities, drainage districts, counties, and SWCDs (responsible for mapping, planning, assistance, and enforcement).
- Agricultural producers: options to comply via smaller buffers (16.5 ft) or approved alternative conservation practices.
- State agencies responsible for funding, mapping, and oversight (DNR, Department of Agriculture).
Potential impacts
- Environmental: expected reductions in nutrient and sediment runoff and improved bank stability and habitat continuity.
- Administrative/financial: local authorities and SWCDs will need resources and technical support to map watercourses, assist landowners, and enforce standards; Department funding and potential funding‑withholding create implementation incentives.
- Landowner compliance costs: costs of establishing buffers or alternative practices, offset by technical and financial assistance programs referenced in the Act.
Limitations / notes
- Full text for applicability to State lands was truncated in the provided document but the bill states it applies to State property.
- Specifics for buffers on drainage systems rely on local drainage authority rules; the Act preserves maintenance needs for drainage infrastructure.
