Schaumburg, IL Environmental Rules: Grading & Drainage (2026)

Schaumburg's grading regulations require a permit for significant changes to the grade or elevation of residential property. This includes projects such as regrading yards, adding fill material, constructing retaining walls, and any site work that alters existing drainage patterns. The Village requires that all lots maintain positive drainage away from building foundations and toward approved discharge points such as streets, swales, or storm sewers. Grading must not direct stormwater onto neighboring properties. A grading plan prepared by a licensed engineer may be required for larger projects, showing existing and proposed contours, drainage flow direction, and erosion control measures. The Cook County Watershed Management Ordinance applies to projects that add significant impervious area or disturb large areas, potentially requiring stormwater detention. Backfill around foundations must be properly compacted to prevent settling that creates negative drainage toward the structure. Sump pump discharge must comply with Village regulations and generally must be directed to the yard, not directly to the storm sewer in some areas. Given Schaumburg's relatively flat terrain and clay soils, proper grading is critical to prevent basement flooding and foundation issues. The Village Engineering Division reviews grading permits and conducts inspections.
