SLCRO §1005.230 (Grading) and §1114.200 (Design Requirements) require grading permits or approved improvement plans before any grading. Erosion and siltation controls are mandatory. Grading that alters watersheds is prohibited.
St. Louis County coordinates stormwater with the Metropolitan Sewer District (MSD). The county's grading rules prohibit altering natural drainage patterns that would impact neighboring properties or storm-sewer capacity. Storm-water facilities in subdivisions (retention ponds, dry basins) are the subdivision trustees' maintenance responsibility under §1005.290. Construction-site siltation controls must be installed before any earth-moving.
Stop-work; remediation order; up to $1,000/day; MSD enforcement may stack additional penalties.
